Abstract (en)

[origin: WO2017111649A1] Described are an eNB and a UE implementing a CSI-RS protocol. The eNB has an ordered set of antenna ports for a wireless communication channel with the UE, a first circuitry operable to compose CSI-RS configuration messages that assign to the UE various CSI-RS groups specifying one or more CSI-RS antenna ports, and a second circuitry to establish an ordered list of CSI-RS antenna ports. The UE has a set of antennas, a first circuitry operable to receive from the eNB various CSI-RS configuration messages assigning to it CSI-RS groups specifying one or more CSI-RS antenna ports, and a second circuitry operable to index CSI-RS antenna ports specified by the CSI-RS groups as an ordered list of CSI-RS antenna ports. The eNB may transmit CSI-RS to the configured UE, and the UE may perform channel state information measurements on the ordered list of CSI-RS antenna ports.
