Summary:A method and apparatus for combined medium access control (MAC) and radio link control (RLC) processing are disclosed. For uplink processing, a combined MAC/RLC (CMR) entity generates an SDU descriptor and allocates protocol data unit (PDU) descriptor resources. A protocol engine (PE) populates a PDU descriptor for each PDU carrying at least a portion of the SDU and generates a MAC PDU in a physical layer shared memory based on the SDU descriptor and the PDU descriptor. The MAC PDU is generated while moving RLC SDU data from the bulk memory to the physical layer shared memory. For downlink processing, received MAC PDUs are stored in the physical layer shared memory. The PE reads MAC and RLC headers in the MAC PDU and populates an SDU segment descriptor (SD) and corresponding PDU descriptors for each SDU segment. The CMR entity merges SDU SDs that comprise a same RLC SDU.
