摘要： A cell within cellular network includes user equipment (UE) that transmits data to a base station (eNB). When a UE does not have data to transmit, it may enter a low power mode (DRX) having silent intervals during which the eNB does not expect to receive a transmission from the UE and the UE is not required to monitor DL control channels from the eNB. While in DRX mode, the UE may detect an event, such as data ready for transmission or a need to request a timing adjustment (TA) update. The UE transmits a scheduling request indicator (SRI) to the eNB in response to detection of the event, wherein the SRI carries information identifying the triggering event.

摘要： A transport block size (TBS) of a first uplink message (RACH Msg3) transmitted on a Physical Uplink Shared Channel (PUSCH) during a random access procedure in a User Equipment (UE) accessing a radio access network may be determined by receiving a pathloss threshold parameter. A downlink pathloss value indicative of radio link conditions between the UE and a base station (eNB) serving the UE is then determined. A smaller value of TBS is selected from a set of TBS values if the determined pathloss value is greater than an operating power level of the UE minus the pathloss threshold parameter. A larger value of TBS is selected if the pathloss value is less than the operating power level of the UE minus the pathloss threshold parameter and the TBS required to transmit the RACH Msg3 exceeds the smaller TBS value.
