3.3 Definitions
Assisting secondary serving HS-DSCH Cell: In addition to the serving HS-DSCH cell, a cell in the secondary
downlink frequency, where the UE is configured to simultaneously monitor a HS-SCCH set and receive HS-DSCH if it
is scheduled in that cell.
Assisting serving HS-DSCH Cell: In addition to the serving HS-DSCH cell, a cell in the same frequency, where the
UE is configured to simultaneously monitor a HS-SCCH set and receive HS-DSCH if it is scheduled in that cell.
HS-DSCH cell set: A set of cells that can be configured together as the serving and secondary serving HS-DSCH cells
for a UE. This term is applicable also to non-serving cells in an active set.
MIMO mode: This term refers to the downlink MIMO configuration with two transmit antennas
MIMO mode with four transmit antennas: This term refers to the downlink MIMO configuration with four transmit
antennas
Multiflow mode: The UE is configured in Multiflow mode when it is configured with an assisting serving HS-DSCH
cell.
Non-time reference cell: An HS-DSCH cell configured for a UE in Multiflow mode that has a different timing than the
time reference cell. If the time reference cell is the Assisting Serving HS-DSCH cell then the non-time reference cell is
the Serving HS-DSCH cell. If the time reference cell is the Serving HS-DSCH Cell, then the non-time reference cell is
the Assisting Serving HS-DSCH cell.
Time reference cell: The (Serving or Assisting Serving, but not Secondary Serving or Assisting Secondary Serving)
HS-DSCH cell acting as the time reference for the uplink HS-DPCCH when the UE is configured in Multiflow mode.
There is only one Time reference cell.
4 Services offered to higher layers
4.1 Transport channels
Transport channels are services offered by Layer 1 to the higher layers. General concepts about transport channels are
described in [12].
A transport channel is defined by how and with what characteristics data is transferred over the air interface. A general
classification of transport channels is into two groups:
- Dedicated channels, using inherent addressing of UE;
- Common channels, using explicit addressing of UE if addressing is needed.
ETSI
3GPP TS 25.211 version 11.5.0 Release 11 9 ETSI TS 125 211 V11.5.0 (2014-07)
4.1.1 Dedicated transport channels
There exists two types of dedicated transport channel, the Dedicated Channel (DCH) and the Enhanced Dedicated
Channel (E-DCH).
4.1.1.1 DCH - Dedicated Channel
The Dedicated Channel (DCH) is a downlink or uplink transport channel. The DCH is transmitted over the entire cell or
over only a part of the cell using e.g. beam-forming antennas.
4.1.1.2 E-DCH – Enhanced Dedicated Channel
The Enhanced Dedicated Channel (E-DCH) is an uplink transport channel in CELL DCH.
4.1.2 Common transport channels
There are six types of common transport channels: BCH, FACH, PCH, RACH, HS-DSCH and E-DCH.
4.1.2.1 BCH - Broadcast Channel
The Broadcast Channel (BCH) is a downlink transport channel that is used to broadcast system- and cell-specific
information. The BCH is always transmitted over the entire cell and has a single transport format.
4.1.2.2 FACH - Forward Access Channel
The Forward Access Channel (FACH) is a downlink transport channel. The FACH is transmitted over the entire cell.
The FACH can be transmitted using power setting described in [16].
4.1.2.3 PCH - Paging Channel
The Paging Channel (PCH) is a downlink transport channel. The PCH is always transmitted over the entire cell. The
transmission of the PCH is associated with the transmission of physical-layer generated Paging Indicators, to support
efficient sleep-mode procedures.
4.1.2.4 RACH - Random Access Channel
The Random Access Channel (RACH) is an uplink transport channel. The RACH is always received from the entire
cell. The RACH is characterized by a collision risk and by being transmitted using open loop power control.
4.1.2.5 Void
4.1.2.6 Void
4.1.2.7 HS-DSCH – High Speed Downlink Shared Channel
The High Speed Downlink Shared Channel is a downlink transport channel shared by several UEs. The HS-DSCH can
be associated with one downlink DPCH or F-DPCH, and one or several Shared Control Channels (HS-SCCH). The HS-
DSCH is transmitted over the entire cell or over only part of the cell using e.g. beam-forming antennas.
4.1.2.7A E-DCH - Enhanced Dedicated Channel
The Enhanced Dedicated Channel (E-DCH) is an uplink transport channel in CELL_FACH state and IDLE mode.
4.2 Indicators
Indicators are means of fast low-level signalling entities which are transmitted without using information blocks sent
over transport channels. The meaning of indicators is specific to the type of indicator.
ETSI
3GPP TS 25.211 version 11.5.0 Release 11 10 ETSI TS 125 211 V11.5.0 (2014-07)
The indicators defined in the current version of the specifications are: Acquisition Indicator (AI), Page Indicator (PI)
and MBMS Notification Indicator (NI).
Indicators may be either boolean (two-valued) or three-valued. Their mapping to indicator channels is channel specific.
Indicators are transmitted on those physical channels that are indicator channels (ICH).
5 Physical channels and physical signals
Physical channels are defined by a specific carrier frequency, scrambling code, channelization code (optional), time
start & stop (giving a duration) and, on the uplink, relative phase (0 or π/2). The downlink E-HICH and E-RGCH are
each further defined by a specific orthogonal signature sequence. Scrambling and channelization codes are specified in
[4]. Time durations are defined by start and stop instants, measured in integer multiples of chips. Suitable multiples of
chips also used in specification are:
Radio frame: A radio frame is a processing duration which consists of 15 slots. The length of a radio
frame corresponds to 38400 chips.
Slot: A slot is a duration which consists of fields containing bits. The length of a slot corresponds
to 2560 chips.
Sub-frame: A sub-frame is the basic time interval for E-DCH and HS-DSCH transmission and E-DCH
and HS-DSCH-related signalling at the physical layer. The length of a sub-frame
corresponds to 3 slots (7680 chips).
The default time duration for a physical channel is continuous from the instant when it is started to the instant when it is
stopped. Physical channels that are not continuous will be explicitly described.
Transport channels are described (in more abstract higher layer models of the physical layer) as being capable of being
mapped to physical channels. Within the physical layer itself the exact mapping is from a composite coded transport
channel (CCTrCH) to the data part of a physical channel. In addition to data parts there also exist channel control parts
and physical signals.
5.1 Physical signals
Physical signals are entities with the same basic on-air attributes as physical channels but do not have transport channels
or indicators mapped to them. Physical signals may be associated with physical channels in order to support the
function of physical channels.
5.2 Uplink physical channels
5.2.1 Dedicated uplink physical channels
There are six types of uplink dedicated physical channels, the uplink Dedicated Physical Data Channel (uplink
DPDCH), the uplink Dedicated Physical Control Channel (uplink DPCCH), the uplink Secondary Dedicated Physical
Control Channel (uplink S-DPCCH), the uplink E-DCH Dedicated Physical Data Channel (uplink E-DPDCH), the
uplink E-DCH Dedicated Physical Control Channel (uplink E-DPCCH) and the uplink Dedicated Control Channel
associated with HS-DSCH transmission (uplink HS-DPCCH).
The DPDCH, the DPCCH, the S-DPCCH, the E-DPDCH, the E-DPCCH and the HS-DPCCH are I/Q code multiplexed
(see [4]).
5.2.1.1 DPCCH, S-DPCCH and DPDCH
The uplink DPDCH is used to carry the DCH transport channel. There may be zero, one, or several uplink DPDCHs on
each radio link.
The uplink DPCCH is used to carry control information generated at Layer 1. The Layer 1 control information consists
of known pilot bits to support channel estimation for coherent detection, transmit power-control (TPC) commands,
ETSI
3GPP TS 25.211 version 11.5.0 Release 11 11 ETSI TS 125 211 V11.5.0 (2014-07)
feedback information (FBI), and an optional transport-format combination indicator (TFCI). The transport-format
combination indicator informs the receiver about the instantaneous transport format combination of the transport
channels mapped to the simultaneously transmitted uplink DPDCH radio frame. There is one and only one uplink
DPCCH on each radio link.
The uplink S-DPCCH is used to carry control information generated at Layer 1. The Layer 1 control information
consists of known pilot bits to support channel sounding and channel estimation for coherent detection. There is up to
one uplink S-DPCCH on each radio link in the case that UL_CLTD_Enabled as defined in [5] is TRUE. Figure 1 shows
the frame structure of the uplink DPDCH, the uplink DPCCH and the uplink S-DPCCH. Each radio frame of length 10
ms is split into 5 subframes, each of 3 slots, each of length T = 2560 chips, corresponding to one power-control
slot
period. The DPDCH, DPCCH and S-DPCCH are always frame aligned with each other.

The parameter k in figure 1 determines the number of bits per uplink DPDCH slot. It is related to the spreading factor
k
SF of the DPDCH as SF = 256/2 . The DPDCH spreading factor may range from 256 down to 4. The spreading factor
of the uplink DPCCH and the uplink S-DPCCH is always equal to 256, i.e. there are 10 bits per uplink DPCCH/S-
DPCCH slot.
The exact number of bits of the uplink DPDCH and the different uplink DPCCH fields (N , N , N , and N ) is

The FBI bits are used to support techniques requiring feedback from the UE to the UTRAN Access Point for operation
of closed loop mode transmit diversity. The use of the FBI bits is described in detail in [5].

There are two types of uplink dedicated physical channels; those that include TFCI (e.g. for several simultaneous
services) and those that do not include TFCI (e.g. for fixed-rate services). These types are reflected by the duplicated
rows of table 2. It is the UTRAN that determines if a TFCI should be transmitted and it is mandatory for all UEs to
support the use of TFCI in the uplink. The mapping of TFCI bits onto slots is described in [3].
In compressed mode, DPCCH slot formats with TFCI fields are changed. There are two possible compressed slot
formats for each normal slot format. They are labelled A and B and the selection between them is dependent on the
number of slots that are transmitted in each frame in compressed mode.
If UL_DTX_Active is TRUE (see [5]), the number of transmitted slots per radio frame may be less than the number
shown in Table 2 and Table 2A.

The pilot bit pattern for S-DPCCH is the same as that for uplink DPCCH with N = 8. The N bits in the S-DPCCH
pilot fixed
are fixed to "10".
The pilot bit patterns are described in table 3 and table 4. The shadowed column part of pilot bit pattern is defined as
FSW and FSWs can be used to confirm frame synchronization. (The value of the pilot bit pattern other than FSWs shall
be "1".)

Multi-code operation is possible for the uplink dedicated physical channels. When multi-code transmission is used,
several parallel DPDCH are transmitted using different channelization codes, see [4]. However, there is only one
DPCCH per radio link, and up to one S-DPCCH in the case that UL_CLTD_Enable is TRUE.
A period of uplink DPCCH transmission prior to the start of the uplink DPDCH transmission (uplink DPCCH power
control preamble) shall be used for initialisation of a DCH. The length of the power control preamble is a higher layer
parameter, N , signalled by the network [5]. The UL DPCCH shall take the same slot format in the power control
pcp
preamble as afterwards, as given in table 2. When N > 0 the pilot patterns of table 3 and table 4 shall be used. The
pcp
timing of the power control preamble is described in [5], subclause 4.3.2.3. The TFCI field is filled with "0" bits.

5.2.1.2 HS-DPCCH
Figure 2A illustrates the frame structure of the HS-DPCCH. The HS-DPCCH carries uplink feedback signalling related
to downlink HS-DSCH transmission and to HS-SCCH orders according to subclause 6A.1.1 in [5]. The feedback
signalling consists of Hybrid-ARQ Acknowledgement (HARQ-ACK) and Channel-Quality Indication (CQI), in case
the UE is configured in MIMO mode or in MIMO mode with four transmit antennas Precoding Control Indication (PCI)
as well and in case the UE is configured in MIMO mode with four transmit antennas the number of transport blocks
preferred (NTBP) as well [3]. Each sub frame of length 2 ms (3*2560 chips) consists of 3 slots, each of length 2560
chips. The HARQ-ACK is carried in the first slot of the HS-DPCCH sub-frame. The CQI, in case the UE is configured
in MIMO mode also the PCI, and in case the UE is configured in MIMO mode with four transmit antennas also the PCI
and the number of UE preferred transport blocks are carried in the second and third slot of a HS-DPCCH sub-frame.
There is at most one HS-DPCCH on each radio link if Secondary_Cell_Enabled as defined in [5] is less than 4 in case
the UE is not configured in MIMO mode with four transmit antennas, 2 in case the UE is configured in MIMO mode
with four transmit antennas and at most two HS-DPCCHs otherwise. The HS-DPCCH(s) can only exist together with an
uplink DPCCH. The timing of the HS-DPCCH relative to the uplink DPCCH is shown in section 7.7 for the case where
one HS-DPCCH exists. In the case where two HS-DPCCH exist, both HS-DPCCHs
