Abstract: A wireless device may receive system information block 1 (SIB1) message of a cell. The SIB1 message may indicate a plurality of configuration parameters comprising a common uplink configuration of an uplink bandwidth part (BWP). The common uplink configuration of the uplink BWP may comprise: a common random access channel (RACH) configuration; a first threshold for determining whether to select a resource associated with a first message 1 (msg1) repetition number, wherein msg1 corresponds to physical random access channel (PRACH) preamble; a second threshold for determining whether to select a resource associated with a second msg1 repetition number; and a second RACH configuration associated with feature combination. The second RACH configuration may comprise a first feature combination preamble parameter that indicates the first msg1 repetition number. The wireless device may determine, based on the first threshold, the first msg1 repetition number, and repeatedly transmit, based on the determined first msg1 repetition number, a PRACH preamble of a random access procedure associated with the first feature combination preamble parameter.

Abstract: A method and apparatus for supporting XR services is provided. The method of a terminal includes receiving from a base station a Radio Resource Control (RRC) message, wherein the RRC message comprises a set of Packet Data Convergence Protocol (PDCP) parameters for a Data Radio Bearer (DRB), establishing a Data Radio Bearer (DRB) based on the set of PDCP parameters, starting a discard timer for a Service Data Unit (SDU) of the DRB and discarding one or more SDUs. In case that the discard timer expires, the terminal performs a first discard operation. In case that successful delivery of the SDU is confirmed by the PDCP status report, the terminal performs a second discard operation.
