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.

3. The method of claim 1, wherein the messagePowerOffsetGroupB parameter is received from the eNB serving the UE.
4. The method of claim 1, wherein the parameters PO _ PRE, ?PREAMBLE-Msg3, MESSAGE_SIZE_GROUP_A, and messagePowerOffsetGroupB are received from the eNB serving the UE.
5. A method for a user equipment (UE) to select a random access preamble message size comprising:
receiving at least one system information block (SIB) from a base station (eNB),
wherein the UE has a maximum transmit power (PMAX), a preamble initial received target power (PO _ PRE) at the eNodeB, a delta preamble (?PREAMBLE-Msg3), a message size group A (MESSAGE_SIZE_GROUP_A), a message size group B (MESSAGE_SIZE_GROUP_B), and a message power offset for group B (messagePowerOffsetGroupB),
