9 8 TS V8.7.0 ( ) 4 Sychroisatio procedures 4.1 Cell search Cell search is the procedure by which a UE acquires time ad frequecy sychroizatio with a cell ad detects the physical layer Cell ID of that cell. E-UTRA cell search supports a scalable overall trasmissio badwidth correspodig to 6 resource blocks ad upwards. The followig sigals are trasmitted i the dowlik to facilitate cell search: the primary ad secodary sychroizatio sigals. 4.2 Timig sychroisatio Radio lik moitorig The dowlik radio lik quality of the servig cell shall be moitored by the UE for the purpose of idicatig out-ofsyc/i-syc status to higher layers. I o-drx mode operatio, the physical layer i the UE shall every radio frame assess the radio lik quality, evaluated over the previous time period defied i [10], agaist thresholds (Q out ad Q i ) defied by relevat tests i [10]. I DRX mode operatio, the physical layer i the UE shall at least oce every DRX period assess the radio lik quality, evaluated over the previous time period defied i [10], agaist thresholds (Q out ad Q i ) defied by relevat tests i [10]. The physical layer i the UE shall i radio frames where the radio lik quality is assessed idicate out-of-syc to higher layers whe the radio lik quality is worse tha the threshold Q out. Whe the radio lik quality is better tha the threshold Q i, the physical layer i the UE shall i radio frames where the radio lik quality is assessed idicate i-syc to higher layers Iter-cell sychroisatio [For example, for cell sites with a multicast physical chael] Trasmissio timig adjustmets Upo receptio of a timig advace commad, the UE shall adjust its uplik trasmissio timig for PUCCH/PUSCH/SRS. The timig advace commad idicates the chage of the uplik timig relative to the curret uplik timig as multiples of 16 T s. The start timig of the radom access preamble is specified i [3]. I case of radom access respose, 11-bit timig advace commad [8], T A, idicates TA values by idex values of T A = 0, 1, 2,..., 1282, where a amout of the time aligmet is give by TA = T A 16. TA is defied i [3]. I other cases, 6-bit timig advace commad [8], T A, idicates adjustmet of the curret TA value, TA,old, to the ew TA value, TA,ew, by idex values of T A = 0, 1, 2,..., 63, where TA,ew = TA,old + (T A 31) 16. Here, adjustmet of TA value by a positive or a egative amout idicates advacig or delayig the uplik trasmissio timig by a give amout respectively. For a timig advace commad received o subframe, the correspodig adjustmet of the timig shall apply from the begiig of subframe +6. Whe the UE s uplik PUCCH/PUSCH/SRS trasmissios i subframe ad subframe +1 are overlapped due to the timig adjustmet, the UE shall trasmit complete subframe ad ot trasmit the overlapped part of subframe +1. If the received dowlik timig chages ad is ot compesated or is oly partly compesated by the uplik timig adjustmet without timig advace commad as specified i [10], the UE chages TA accordigly.

The term resource elemet eergy also deotes the average eergy take over all costellatio poits for the modulatio scheme applied. Uplik power cotrol determies the average power over a SC-FDMA symbol i which the physical chael is trasmitted. 5.1 Uplik power cotrol Uplik power cotrol cotrols the trasmit power of the differet uplik physical chaels.
