Abstract:
1. A data transmission method comprising: segmenting or concatenating, by one or more processors, radio layer control (RLC) service data units (SDUs) to RLC protocol data units (PDUs) that fit within a size of a total size of RLC PDU(s) indicated by a lower protocol layer processor, each RLC PDU having a header and a data field; mapping, by the one or more processors, a single two bit field including a first bit and a second bit to the header for each of the RLC PDUs, wherein a number of bits included in the single two bit field is two regardless of a number of SDUs included in the data field; the first bit and the second bit indicating only (i) whether or not the data field of its corresponding RLC PDU begins with a segment of an RLC SDU, and (ii) whether or not the data field ends with a segment of an RLC SDU; transmitting, by a transmitter, a data packet including one or more of the RLC PDUs.
