  • Patent number: 11855718
    Abstract: Channel state information (CSI) feedback in a wireless communication system is disclosed. User equipment transmits a CSI feedback signal via a Physical Uplink Control CHannel (PUCCH). If the UE is configured in a first feedback mode, the CSI comprises a first report jointly coding a Rank Indicator (RI) and a first precoding matrix indicator (PMI1), and a second report coding Channel Quality Indicator (CQI) and a second precoding matrix indicator (PMI2). If the UE is configured in a second feedback mode, the CSI comprises a first report coding RI, and a second report coding CQI, PMI1 and PMI2. The jointly coded RI and PMI1 employs codebook sub-sampling, and the jointly coding PMI1, PMI2 and CQI employs codebook sub-sampling.

  • Publication number: 20220303082
    Abstract: Dual-connectivity for the User Equipment (UE) in a cellular network is performed by monitoring a plurality of cells. During dual-connectivity, the UE may be simultaneously connected to one serving cell for the Control Plane (C-plane) and to another serving cell, controlled by a different eNodeB, for the User Plane (U-plane). In another embodiment, the dual-connected UE monitors a Physical Downlink Control Channel (PDCCH) from the first eNB and monitors an EPDCCH from the second eNB.
