1. A method for selecting 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, comprising:
receiving a pathloss threshold parameter;
estimating a downlink pathloss value indicative of radio link conditions between the UE and a base station (eNB) serving the UE;
selecting from a set of TBS values a smaller value of TBS if the determined pathloss value is greater than an operating power level of the UE minus the pathloss threshold parameter; and
sending a random access preamble based on the selected TBS.
