2 Set of channels
The radio subsystem provides a certain number of logical channels that can be separated into two categories according
to 3GPP TS 44.003, 3GPP TS 43.064 and 3GPP TS 43.052:
1) The traffic channels (TCH): they are intended to carry two types of user information streams: encoded speech
and data. The following types of traffic channels are defined: Bm or full-rate (TCH/F), Lm or half-rate (TCH/H),
cell broadcast (CBCH), full rate packet data ((EC-)PDTCH/F) and half rate packet data (PDTCH/H) traffic
channels. For the purpose of this series of technical specifications, the following traffic channels are
distinguished:
- full rate speech TCH (TCH/FS);
- enhanced full rate speech TCH (TCH/EFS)
- half rate speech TCH (TCH/HS);
- adaptive full rate speech TCH (TCH/AFS);
- adaptive half rate speech TCH (TCH/AHS);
- adaptive half rate 8-PSK speech TCH (O-TCH/AHS);
- adaptive full rate wideband speech (TCH/WFS)
- adaptive full rate 8-PSK wideband speech (O-TCH/WFS)
- adaptive half rate 8-PSK wideband speech (O-TCH/WHS)
- 28,8 kbit/s full rate data E-TCH (E-TCH/F28.8);
ETSI

---------------------- Page: 8 ----------------------
3GPP TS 45.001 version 13.2.0 Release 13 8 ETSI TS 145 001 V13.2.0 (2016-08)
- 32,0 kbit/s full rate data E-TCH (E-TCH/F32.0);
- 43,2 kbit/s full rate data E-TCH (E-TCH/F43.2);
- 14,4 kbit/s full rate data TCH (TCH/F14.4);
- 9,6 kbit/s full rate data TCH (TCH/F9.6);
- 4,8 kbit/s full rate data TCH (TCH/F4.8);
- 4,8 kbit/s half rate data TCH (TCH/H4.8);
- ≤ 2,4 kbit/s full rate data TCH (TCH/F2.4);
- ≤ 2,4 kbit/s half rate data TCH (TCH/H2.4);
- cell broadcast channel (CBCH);
- full rate packet data traffic channel (PDTCH/F);
- extended coverage full rate packet data traffic channel (EC-PDTCH/F);
- half rate packet data traffic channel (PDTCH/H).
Adaptive speech traffic channels are channels for which part of the radio bandwidth is reserved for transmission
of in band signalling to allow in call adaptation of the speech and channel codec. 8 full rate block structures for
TCH/AFS, 8 half rate block structures for O-TCH/AHS, 6 half rate block structures for TCH/AHS, 3 full rate
block structures for TCH/WFS, 5 full rate block structures for O-TCH/WFS and 3 half rate block structures for
O-TCH/WHS are defined.
All channels are bi-directional unless otherwise stated. Unidirectional downlink full rate channels, TCH/FD are
defined as the downlink part of the corresponding TCH/F. Unidirectional uplink full rate channels are FFS.
The assigned uplink and downlink (EC-)PDTCHs are used independently of each other. Dependent assignment
of uplink and downlink is possible. A PDTCH/F may be defined either in BTTI configuration or in RTTI
configuration. An EC-PDTCH/F shall be defined in BTTI configuration.
Multislot configurations for circuit switched connections are defined as multiple (1 up to 8) full rate channels
assigned to the same MS. At least one channel shall be bi-directional (TCH/F). The multislot configuration is
symmetric if all channels are bi-directional (TCH/F) and asymmetric if at least one channel is unidirectional
(TCH/FD).
High Speed Circuit Switched Data (HSCSD) is an example of multislot configuration, in which all channels shall
have the same channel mode.
NOTE: For the maximum number of timeslots to be used for a HSCSD configuration, see 3GPP TS 23.034.
Multislot configurations for packet switched connections are defined as multiple (1 up to 8) (EC-)PDTCH/Us
and one (EC-)PACCH for one mobile originated communication, or multiple (1 up to 8) (EC-)PDTCH/Ds and
one (EC-)PACCH for one mobile terminated communication respectively, assigned to the same MS. In this
context 'assignment' refers to the list of PDCHs in BTTI configuration or PDCH-pairs in RTTI configuration that
may dynamically carry the (EC-)PDTCHs for that specific MS. One exception applies in case of EC operation
where the PDCHs of a mobile originated communication carry the EC-PDTCHs by means of a fixed uplink
allocation.
The (EC-)PACCH shall have the same TTI configuration as the (EC-)PDTCH that it is associated with. The
rules for mapping of (EC-)PACCH onto physical channels are specified in 3GPP TS 44.060. In the case of point-
to-multipoint transmission for MBMS, multiple (1 up to 5) PDTCH/Ds and one PACCH can be assigned for
simultaneous communication with multiple mobiles.
Multislot configurations for dual transfer mode are defined as one bi-directional, traffic channel (TCH/H,
O-TCH/H, TCH/F, O-TCH/F or E-TCH/F) and one packet channel combination. The packet channel
combination may consist of multiple PDTCH/Us and one PACCH for one mobile originated communication, or
multiple PDTCH/Ds and one PACCH for one mobile terminated communication respectively, assigned to the
same MS. The PDTCHs may be transmitted either in BTTI configuration or in RTTI configuration. The rules for
mapping of PACCH onto physical channels are specified in 3GPP TS 44.060.

3GPP TS 45.001 version 13.2.0 Release 13 9 ETSI TS 145 001 V13.2.0 (2016-08)
An MS capable of dual transfer mode (DTM) shall support, as a minimum, DTM multislot class 5, which utilises
the two-timeslot channelization method, i.e. a single TCH/F or O-TCH/F plus a single PDTCH/F. In addition,
the MS supporting DTM shall support TCH/H + PDCH/F configuration with the adaptive multirate (AMR)
speech coder for voice coding.
2) The signalling channels: these can be sub-divided into BCCH (broadcast control channel, including packet
broadcast control channel (PBCCH), see sub clause 1.3, and extended coverage broadcast control channel (EC-
BCCH)), CCCH (common control channel, including packet common control channel (PCCCH), see sub clause
1.3, and extended coverage common control channel (EC-CCCH)), SDCCH (stand-alone dedicated control
channel), (P)ACCH ((packet) associated control channel, including extended coverage packet associated control
channel (EC-PACCH)), packet timing advance control channel (PTCCH) and CTSCCH (CTS control channel).
An associated control channel is always assigned in conjunction with, either a TCH, or an SDCCH. A packet
associated control channel is always assigned in conjunction to one or multiple (EC-)PDTCH, concurrently
assigned to one MS. Two types of ACCH for circuit switched connections are defined: continuous stream (slow
ACCH) and burst stealing mode (fast ACCH). For the purpose of this series of technical specifications, the
following signalling channels are distinguished:
- stand-alone dedicated control channel, four of them mapped on the same basic physical channel as the CCCH
(SDCCH/4);
- stand-alone dedicated control channel, eight of them mapped on a separate basic physical channel
(SDCCH/8);
- full rate fast associated control channel (FACCH/F);
- enhanced circuit switched full rate fast associated control channel (E-FACCH/F);
- half rate fast associated control channel (FACCH/H);
- full rate octal fast associated control channel (O-FACCH/F);
- half rate octal fast associated control channel (O-FACCH/H);
- slow, TCH/F, O-TCH/F or E-TCH/F associated, control channel (SACCH/TF);
- slow, TCH/F or O-TCH/F associated, control channel for enhanced power control (SACCH/TPF);
- slow, TCH/H or O-TCH/H associated, control channel (SACCH/TH);
- slow, TCH/H or O-TCH/H associated, control channel for enhanced power control (SACCH/TPH);
- slow, TCH/F, O-TCH/F or E-TCH/F associated, control channel for multislot configurations (SACCH/M);
- slow, TCH/F or O-TCH/F associated, control channel for enhanced power control in multislot configurations
(SACCH/MP);
- slow, TCH/F associated, control channel for CTS (SACCH/CTS);
- slow, SDCCH/4 associated, control channel (SACCH/C4);
- slow, SDCCH/8 associated, control channel (SACCH/C8);
- packet associated control channel (PACCH);
- extended coverage packet associated control channel (EC-PACCH);
- packet timing advance control channel (PTCCH);
- broadcast control channel (BCCH);
- packet broadcast control channel (PBCCH);
- extended coverage broadcast control channel (EC-BCCH);
- random access channel (i.e. uplink CCCH) (RACH);
- packet random access channel (i.e. uplink PCCCH) (PRACH);

---------------------- Page: 10 ----------------------
3GPP TS 45.001 version 13.2.0 Release 13 10 ETSI TS 145 001 V13.2.0 (2016-08)
- extended coverage random access channel (i.e. uplink EC-CCCH) (EC-RACH);
- paging channel (part of downlink CCCH) (PCH);
- extended coverage paging channel (part of downlink EC-CCCH) (EC-PCH);
- packet paging channel (part of downlink PCCCH) (PPCH);
- access grant channel (part of downlink CCCH) (AGCH);
- packet access grant channel (part of downlink PCCCH) (PAGCH);
- extended coverage access grant channel (part of downlink EC-CCCH) (EC-AGCH);
- notification channel (part of downlink CCCH) (NCH);
- CTS beacon channel (part of downlink CTSCCH) (CTSBCH-FB and CTSBCH-SB);
- CTS paging channel (part of downlink CTSCCH) (CTSPCH);
- CTS access request channel (part of uplink CTSCCH) (CTSARCH);
- CTS access grant channel (part of downlink CTSCCH) (CTSAGCH);
- enhanced inband associated control channel (E-IACCH);
- enhanced power control channel (EPCCH);
- enhanced power control channel for multislot configurations (EPCCH/M);
- packet random access channel for MBMS (MPRACH).
All associated control channels have the same direction (bi-directional or unidirectional) as the channels they are
associated to. The unidirectional SACCH/MD, SACCH/MPD or EPCCH/MD are defined as the downlink part
of SACCH/M, SACCH/MP or EPCCH/M respectively.
When there is no need to distinguish between different sub-categories of the same logical channel, only the generic
name will be used, meaning also all the sub-categories, irrespective of modulation used (SACCH will mean all
categories of SACCHs, SACCH/T will mean both the slow, TCH associated, control channels with and without
enhanced power control, etc.). Also EC-channels are considered to be a sub-category of the same logical channels as
non-EC-channels, unless otherwise stated.
The logical channels mentioned above are mapped on physical channels that are described in this set of technical
specifications. The different physical channels provide for the transmission of information pertaining to higher layers
according to a block structure.
3 Reference configuration
For the purpose of elaborating the physical layer specification, a reference configuration of the transmission chain is
used as shown in annex A. This reference configuration also indicates which parts are dealt with in details in which
technical specification. It shall be noted that only the transmission part is specified, the receiver being specified only via
the overall performance requirements. With reference to this configuration, the technical specifications in the 45 series
