CSI-RS ENHANCEMENT FOR PORT SELECTION CODEBOOK WITH CHANNEL RECIPROCITY - A simplified explanation of the abstract
This abstract first appeared for US patent application 17442035 titled 'CSI-RS ENHANCEMENT FOR PORT SELECTION CODEBOOK WITH CHANNEL RECIPROCITY
Simplified Explanation
The present disclosure is about enhancing the Channel State Information-Reference Signal (CSI-RS) for Port Selection Codebook with Channel Reciprocity in a cellular base station.
- The cellular base station includes at least one antenna, at least one radio, and a processor.
- The base station sends a Radio Resource Control (RRC) message to a wireless device.
- The base station provides a CSI-RS to the wireless device through one or more ports based on the RRC message.
- The RRC message contains information about the density of the CSI-RS, time domain locations of the CSI-RS, subset of ports for the wireless device to measure the CSI-RS, and subset of Code Division Multiplexing (CDM) groups for the wireless device to measure the CSI-RS.
Original Abstract Submitted
The present disclosure relates to apparatus, methods, computer-readable storage medium and computer program product for CSI-RS enhancement for Port Selection Codebook with Channel Reciprocity. A cellular base station, comprising: at least one antenna; at least one radio coupled to the at least one antenna; and a processor coupled to the at least one radio; wherein the cellular base station is configured to: provide a Radio Resource Control (RRC) message to a wireless device; and provide a Channel State Information-Reference Signal (CSI-RS) to the wireless device via one or more ports based on the RRC message, wherein, the RRC message at least indicates one or more of: information on a density of the CSI-RS, information on time domain locations of the CSI-RS, information on a subset of ports for the wireless device to measure the CSI-RS, and information on a subset of Code Division Multiplexing (CDM) groups for the wireless device to measure the CSI-RS.
