  • Patent number: 10911170
    Abstract: A method and apparatus for multiplexing demodulation reference signals and a communication system. The method for multiplexing includes: transmitting data and DM-RSs by using one or more time-frequency resource blocks; the DM-RSs of each UE or each data stream occupy a part of frequency-domain resources of the time-frequency resource blocks, the DM-RSs of a part of UEs or data streams are superimposed on identical time-domain resources in a manner of frequency-division multiplexing, and the DM-RSs of a part of the UEs or data streams are superimposed on identical time-frequency resources in a manner of code-division multiplexing. Hence, even if in a case of massive UEs access, the DM-RSs may be multiplexed within given time-frequency resources, while performance of transmission may still be ensured.

  • Patent number: 10660066
    Abstract: An apparatus and method for paging a UE and a communications system. The method includes: calculating a first-grade paging group index based on an inherent identity of the UE, or based on an inherent identity of the UE and a network configuration parameter; calculating a second-grade paging group index based on a network identity allocated by an MME; receiving indication information for indicating paging group indices transmitted by a base station; determining whether the information contained in the indication information is consistent with the first-grade paging group index and the second-grade paging group index; and decoding a downlink data channel to determine whether the UE is paged when it is consistent. Hence, different paging groups may have identical or approximate numbers of UEs, which may reduce a probability of “false paging” of the overall cell.
