`Synchronisation procedures
`
`Cell search
`4.1
`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
`
`Radio link monitoring
`4.2.1
`The downlink radio link quality of the serving cell shall be monitored by the UE for the purpose of indicating radio
`problem detection status to higher layers. The radio problem detection may be based on cell-specific reference signals.
`
`In non-DRX mode operations, the physical layer in the UE shall every radio frame check the quality, measured over the
`previous [200ms] period, against thresholds (Qout and Qin) defined implicitly by relevant tests in [6].
`
`The UE shall indicate radio problem detection to higher layers when the quality is worse than the threshold Qout and
`continue until the quality is better than the threshold Qin.
`
`The start and stop of the radio problem detection monitoring are triggered by higher layers.
`
`Inter-cell synchronisation
`4.2.3
`[For example, for cell sites with a multicast physical channel]
`
`Transmission timing adjustments
`4.2.4
`Upon reception of a timing advance command, the UE shall adjust its uplink transmission timing. The timing advance
`command is expressed in multiples of 16 sT and is relative to the current uplink timing.
`
`For a timing advance command received on subframe n, the corresponding adjustment of the timing shall apply from
`the beginning of subframe n+6.
`

`
`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
`DFT-SOFDM symbol in which the physical channel is transmitted.
`
`Uplink power control
`5.1
`Uplink power control controls the transmit power of the different uplink physical channels.
`
`A cell wide overload indicator (OI) is exchanged over X2 for inter-cell power control. An indication X also exchanged
`over X2 indicates PRBs that an eNodeB scheduler allocates to cell edge UEs and that will be most sensitive to inter-cell
`interference.
`
`[Note: Above lines regarding OI, X and X2 to be moved to an appropriate RAN3 spec when it becomes available]

`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, frequency position and preamble format)
`2. Parameters for determining the root sequences and their cyclic shifts in the preamble sequence set for the cell
`CSN ), and set type (unrestricted or restricted set))
`(index to root sequence table, cyclic shift (
`
`Physical non-synchronized random access procedure
`6.1
`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:
`1. Layer 1 procedure is triggered upon request of a preamble transmission by higher layers.
`2. A preamble index, preamble transmission power (PREAMBLE_TRANSMISSION_POWER), associated RA-
`RNTI, random access window ([RA_WINDOW_BEGIN—RA_WINDOW_END]) and PRACH resource are
`indicated by higher layers as part of the request.
`3. A preamble sequence is then selected from the preamble sequence set using the preamble index.
`4. A single preamble transmission then occurs using the selected preamble sequence with transmission power
`PREAMBLE_TRANSMISSION_POWER on the indicated PRACH resource.
