  • Communication device and method thereof for D2D communications
    Patent number: 10524162
    Abstract: A method for receiving a plurality of data packets is disclosed. The method includes: receiving MAC PDUs from a source UE of the wireless network through a relay UE, a base station and directly from the source UE, wherein the MAC PDUs are composed of RLC PDUs and RLC PDU segments; demultiplexing the MAC PDUs to retrieve the RLC PDUs and the RLC PDU segments based on a header field of each MAC PDU; reordering the RLC PDUs and the RLC PDU segments and performing a duplicate detection of the RLC PDUs and the RLC PDU segments according to TSNs, wherein each TSN is included in a header field of each RLC PDU and each RLC PDU segment; and reassembling the RLC PDUs and the RLC PDU segments into RLC SDUs using information included in the header field of each RLC PDU and each RLC PDU segment.
    Type: Grant
    Filed: June 4, 2018
    Date of Patent: December 31, 2019
    Assignee: Industrial Technology Research Institute
    Inventors: Chun-Yuan Chiu, Ruo-Fei Ma, Nian Xia, Hsiao-Hwa Chen

  • Communication system, communication device, base station and method thereof for D2D communications
    Patent number: 10021596
    Abstract: A method for transmitting a plurality of data packets is disclosed. The method includes: receiving one or more first medium access control (MAC) protocol data units (PDUs) which include a plurality of radio link control (RLC) PDUs intended for a destination UE from a source UE; demultiplexing the first MAC PDUs to retrieve the RLC PDUs based on a header field of each first MAC PDU; generating a plurality of RLC PDU segments from one or more of the RLC PDUs or a plurality of RRLC (Relay RLC) PDUs from all of the RLC PDUs according to one or more MAC PDU sizes, wherein the RRLC is a protocol layer between the MAC layer and the RLC layer; multiplexing the RLC PDUs and the RLC PDU segments or the RRLC PDUs into one or more second MAC PDUs; and transmitting the second MAC PDUs to the destination UE.
