System for wireless communication and a method for providing wireless communication

摘要

The present invention relates to a system for wireless communication comprising a first transceiver circuitry (BS) connected to a plurality of virtual antenna ports of an antenna arrangement; each virtual antenna port is a combination of one or more physical antenna ports. The first transceiver circuitry (BS) is configured to: communicate with a second transceiver circuitry (UE) via the antenna ports of the antenna arrangement; receive primary beamshaping information related to a first link (Downlink) between the first transceiver circuitry (BS) and the second transceiver circuitry (UE); determine secondary beamshaping information related to a second link (Uplink) between the second transceiver circuitry (UE) and the first transceiver circuitry (BS); and apply at least one weight vector based on the primary and secondary beamshaping information for subsequent transmission of signals from the first transceiver circuitry (BS) via the plurality of virtual antenna ports of the antenna arrangement.

1. An apparatus for wireless communication, comprising:
antenna arrangement comprising a set of virtual antenna ports, each virtual antenna port being a combination of one or more physical antenna ports of the antenna arrangement; and a first transceiver circuitry connected to the plurality of virtual antenna ports of the antenna arrangement, said first transceiver circuitry being configured to:
communicate with a second transceiver circuitry via the virtual antenna ports of said antenna arrangement,receive primary beamshaping information related to a first signal transmitted from said first transceiver circuitry to said second transceiver circuitry,determine secondary beamshaping information related to a second signal transmitted from said second transceiver circuitry to said first transceiver circuitry,apply at least one weight vector based on said primary and secondary beamshaping information for subsequent transmission of signals from said first transceiver circuitry via the plurality of virtual antenna ports of said antenna arrangement,measure signal parameters related to said second signal to determine said secondary beamshaping information based on statistics of the measured signal parameters, andcalculate direction of departure (DOD) variances of said primary and secondary beamshaping information to select the weight vector based on the calculated DOD variances.
