Abstract: 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.

Abstract: Simplified communication between user equipment and a neighboring cell not the primary cell is achieved by restricting the transmission parameters, such as bandwidth, of the neighboring cell transmission and provision of simplified secondary baseband processor in the user equipment.

Abstract translation: 在访问无线电接入网络的用户设备（UE）中的随机接入过程期间在物理上行链路共享信道（PUSCH）上发送的第一上行链路消息（RACH Msg3）的传输块大小（TBS）可以通过接收路径损耗来确定 阈值参数。 然后确定表示UE和服务于UE的基站（eNB）之间的无线电链路状况的下行链路路径损耗值。 如果确定的路径损耗值大于UE的工作功率级别减去路径损耗阈值参数，则从一组TBS值中选择较小的TBS值。 如果路径损耗值小于UE的工作功率级别减去路径损耗阈值参数，并且发送RACH Msg3所需的TBS超过较小的TBS值，则选择较大的TBS值。
