4 Synchronisation procedures
4.1 Cell search
Cell search is the procedure by which a UE acquires time and frequency synchronization with a cell and detects the
physical layer Cell ID of that cell. E-UTRA cell search supports a scalable overall transmission bandwidth
corresponding to 6 resource blocks and upwards.
The following signals are transmitted in the downlink to facilitate cell search: the primary and secondary
synchronization signals.
4.2 Timing synchronisation
4.2.1 Radio link monitoring
The downlink radio link quality of the serving cell shall be monitored by the UE for the purpose of indicating out-of-
sync/in-sync status to higher layers.
In non-DRX mode operation, the physical layer in the UE shall every radio frame assess the radio link quality,
evaluated over the previous time period defined in [10], against thresholds (Q and Q ) defined by relevant tests in
out in
[10].
In DRX mode operation, the physical layer in the UE shall at least once every DRX period assess the radio link quality,
evaluated over the previous time period defined in [10], against thresholds (Q and Q ) defined by relevant tests in
out in
[10].
The physical layer in the UE shall in radio frames where the radio link quality is assessed indicate out-of-sync to higher
layers when the radio link quality is worse than the threshold Q . When the radio link quality is better than the
out
threshold Q , the physical layer in the UE shall in radio frames where the radio link quality is assessed indicate in-sync
in
to higher layers.
4.2.2 Inter-cell synchronisation
No functionality is specified in this section in this release.
4.2.3 Transmission timing adjustments
Upon reception of a timing advance command, the UE shall adjust its uplink transmission timing for
PUCCH/PUSCH/SRS. The timing advance command indicates the change of the uplink timing relative to the current
uplink timing as multiples of 16 T . The start timing of the random access preamble is specified in [3].
s
In case of random access response, 11-bit timing advance command [8], T , indicates N values by index values of
A TA
T = 0, 1, 2, ., 1282, where an amount of the time alignment is given by N = T ×16. N is defined in [3].
A TA A TA
In other cases, 6-bit timing advance command [8], T , indicates adjustment of the current N value, N , to the new
A TA TA,old
N value, N , by index values of T = 0, 1, 2,., 63, where N = N + (T −31)×16. Here, adjustment of N
TA TA,new A TA,new TA,old A TA
value by a positive or a negative amount indicates advancing or delaying the uplink transmission timing by a given
amount respectively.
For a timing advance command received on subframe n, the corresponding adjustment of the timing shall apply from
the beginning of subframe n+6. When the UE’s uplink PUCCH/PUSCH/SRS transmissions in subframe n and subframe
n+1 are overlapped due to the timing adjustment, the UE shall transmit complete subframe n and not transmit the
overlapped part of subframe n+1.
If the received downlink timing changes and is not compensated or is only partly compensated by the uplink timing
adjustment without timing advance command as specified in [10], the UE changes N accordingly.

5 Power control
Downlink power control determines the energy per resource element (EPRE). The term resource element energy
denotes the energy prior to CP insertion. The term resource element energy also denotes the average energy taken over
all constellation points for the modulation scheme applied. Uplink power control determines the average power over a
SC-FDMA symbol in which the physical channel is transmitted.
5.1 Uplink power control
Uplink power control controls the transmit power of the different uplink physical channels.
A cell wide overload indicator (OI) and a High Interference Indicator (HII) to control UL interference are defined in [9].
5.1.1 Physical uplink shared channel
5.1.1.1 UE behaviour
The setting of the UE Transmit power P for the physical uplink shared channel (PUSCH) transmission in
PUSCH
subframe i is defined by
P (i) = min{P ,10log (M (i)) + P ( j) + α( j) ⋅ PL + Δ (i) + f (i)} [dBm]
PUSCH CMAX 10 PUSCH O_PUSCH TF

layers for j=0 and 1. For PUSCH (re)transmissions corresponding to a semi-persistent grant then j=0 , for
PUSCH (re)transmissions corresponding to a dynamic scheduled grant then j=1 and for PUSCH
(re)transmissions corresponding to the random access response grant then j=2. P (2) = 0 and
O_UE_PUSCH
P (2) = P + Δ , where the parameter
O_NOMINAL_PUSCH O_PRE PREAMBLE _ Msg3
PREAMBLE_INITIAL_RECEIVED_TARGET_POWER [8] ( P ) and Δ are signalled
O_PRE PREAMBLE _ Msg3
from higher layers.

5.2 Downlink power allocation
The eNodeB determines the downlink transmit energy per resource element.
A UE may assume downlink cell-specific RS EPRE is constant across the downlink system bandwidth and constant
across all subframes until different cell-specific RS power information is received. The downlink reference-signal
EPRE can be derived from the downlink reference-signal transmit power given by the parameter Reference-signal-
power provided by higher layers. The downlink reference-signal transmit power is defined as the linear average over the
power contributions (in [W]) of all resource elements that carry cell-specific reference signals within the operating
system bandwidth.
The ratio of PDSCH EPRE to cell-specific RS EPRE among PDSCH REs (not applicable to PDSCH REs with zero
EPRE) for each OFDM symbol is denoted by either ρ or ρ according to the OFDM symbol index as given by
A B
Table 5.2-2. In addition, ρ and ρ are UE-specific.
A B
The UE may assume that for 16 QAM, 64 QAM, spatial multiplexing with more than one layer or for PDSCH
transmissions associated with the multi-user MIMO transmission scheme,
ρ is equal toδ + P +10log (2) [dB] when the UE receives a PDSCH data transmission using
A power-offset A 10
precoding for transmit diversity with 4 cell-specific antenna ports according to Section 6.3.4.3 of [3];
ρ is equal toδ + P [dB] otherwise
A
power-offset A
whereδ is 0 dB for all PDSCH transmission schemes except multi-user MIMO and where P is a UE specific
power-offset A
parameter provided by higher layers.
If UE-specific RSs are present in the PRBs upon which the corresponding PDSCH is mapped, the ratio of PDSCH
EPRE to UE-specific RS EPRE within each OFDM symbol containing UE-specific RSs shall be a constant, and that
constant shall be maintained over all the OFDM symbols containing the UE-specific RSs in the corresponding PRBs. In
addition, the UE may assume that for 16QAM or 64QAM, this ratio is 0 dB.
The cell-specific ratio ρ / ρ is given by Table 5.2-1 according to cell-specific parameter P signalled by higher
B A B
layers and the number of configured eNodeB cell specific antenna ports.

6 Random access procedure
Prior to initiation of the non-synchronized physical random access procedure, Layer 1 shall receive the following
information from the higher layers:
1. Random access channel parameters (PRACH configuration and frequency position)
2. Parameters for determining the root sequences and their cyclic shifts in the preamble sequence set for the cell
(index to logical root sequence table, cyclic shift ( N ), and set type (unrestricted or restricted set))

6.1 Physical non-synchronized random access procedure
From the physical layer perspective, the L1 random access procedure encompasses the transmission of random access
preamble and random access response. The remaining messages are scheduled for transmission by the higher layer on
the shared data channel and are not considered part of the L1 random access procedure. A random access channel
occupies 6 resource blocks in a subframe or set of consecutive subframes reserved for random access preamble
transmissions. The eNodeB is not prohibited from scheduling data in the resource blocks reserved for random access
channel preamble transmission.
The following steps are required for the L1 random access procedure:
ETSI
3GPP TS 36.213 version 8.8.0 Release 8 17 ETSI TS 136 213 V8.8.0 (2009-10)
1. Layer 1 procedure is triggered upon request of a preamble transmission by higher layers.
2. A preamble index, a target preamble received power (PREAMBLE_RECEIVED_TARGET_POWER), a
corresponding RA-RNTI and a PRACH resource are indicated by higher layers as part of the request.
3. A preamble transmission power P is determined as
PRACH
P = min{ P , PREAMBLE_RECEIVED_TARGET_POWER + PL}_[dBm], where P is the
PRACH
CMAX CMAX
configured UE transmitted power defined in [6] and PL is the downlink pathloss estimate calculated in the
UE.
4. A preamble sequence is selected from the preamble sequence set using the preamble index.
5. A single preamble is transmitted using the selected preamble sequence with transmission power P on the
PRACH
indicated PRACH resource.
6. Detection of a PDCCH with the indicated RA-RNTI is attempted during a window controlled by higher layers
(see [8], clause 5.1.4). If detected, the corresponding PDSCH transport block is passed to higher layers. The
higher layers parse the transport block and indicate the 20-bit UL-SCH grant to the physical layer, which is
processed according to section 6.2.
6.1.1 Timing
For the L1 random access procedure, UE’s uplink transmission timing after a random access preamble transmission is
as follows.
a. If a PDCCH with associated RA-RNTI is detected in subframe n, and the corresponding DL-SCH
transport block contains a response to the transmitted preamble sequence, the UE shall, according to
the information in the response, transmit an UL-SCH transport block in the first subframe n + k ,
k ≥ 6 , if the UL delay field in section 6.2 is set
