US 2021/0242912 A1 · WIRELESS COMMUNICATION METHOD AND WIRELESS COMMUNICATION DEVICE

Abstract

A wireless communication method and a wireless communication device. The method comprises: a sending side device generating a common sequence so as to send to a plurality of receiving side devices; each of the plurality of receiving side devices determining a first analogue weight parameter according to a receiving situation of the common sequence, and determining an antenna configuration for sending a pre-determined pilot frequency signal corresponding to the receiving side device according to the determined first analogue weight parameter so as to send the pre-determined pilot frequency signal to the sending side device; and the sending side device determining a second analogue weight parameter regarding the receiving side device according to a receiving situation of the pre-determined pilot frequency signal, and determining an antenna configuration for sending data regarding the receiving side device according to the determined second analogue weight parameter so as to send the data to the receiving side device.

Dependent claims

A User Equipment (UE) with a plurality of antennas in a communication system, comprising one or more processors configured to:

determine, based on reception of channel state information reference signal (CSI-RS) from a Base Station (BS) in the communication system, a downlink receiving beam, the downlink receiving beam being determined in accordance to a criterion of maximizing received signal power or a criterion of maximizing Signal-to-Interference Ratio;
and
determine, based on the downlink receiving beam, an uplink transmitting beam for transmitting Sounding Reference Signal (SRS) corresponding to the UE so as to transmit the SRS to the BS,
wherein the plurality of antennas are configured to receive one or more control instructions from the BS,
wherein the one or more processors are further configured to acquire at least one of the following information based on the one or more control instructions:
the first period of time of transmitting the CSI-RS, the number of times for transmitting the CSI-RS, the second period of time of transmitting the SRS, and the number of times for transmitting the SRS.
