  • Patent number: 10404345
    Abstract: Measurements and Channel State Information (CSI) feedback are configured using communications between a network and user equipment (UE). The communications includes a first signaling from a network component to the UE indicating one or more reference signal (RS) resource configurations, a second signaling indicating one or more interference measurement (IM) resource configurations, and a third signaling indicating a CSI report configuration, wherein the CSI report configuration indicates a subset of the one or more RS resource configurations and a subset of the one or more IM resource configurations. The UE establishes a RS based measurement according to the subset of the one or more RS resource configurations and an IM according to the subset of the one or more IM resource configurations. The UE then generates and sends to the network a CSI report in accordance with the CSI report configuration and using the RS based measurement and the IM.

  • Patent number: 10389468
    Abstract: A method and apparatus for allocating and processing sequences in a communication system is disclosed. The method includes: dividing sequences in a sequence group into multiple sub-groups, each sub-group corresponding to its own mode of occupying time frequency resources; selecting sequences from a candidate sequence collection corresponding to each sub-group to form the sequences in the sub-group by: the sequences in a sub-group i in a sequence group k being composed of n sequences in the candidate sequence collection, the n sequences making a |ri/Ni?ck/Np1| or |(ri/Ni?ck/Np1) modu mk,i| function value the smallest, second smallest, till the nth smallest respectively; allocating the sequence group to cells, users or channels. It prevents the sequences highly correlated with the sequences of a specific length from appearing in other sequence groups, thus reducing interference, avoiding the trouble of storing the lists of massive sequence groups.
