A system and method for an efficient port switching technique for line-of-sight multiple-input multiple-output communications by a base station is provided. The base station includes an antenna array comprising a first number of antenna ports. The base station also includes a transceiver configured to communicate in a wireless communication medium. The base station further includes a processor. The processor is configured to determine, based on the wireless communication medium, one or more parameters of the base station or a receive base station. The processor also is configured to select, based on the one or more first parameters and one or more second parameters, a second number of antenna ports to perform a communication with the receive base station.

Methods, systems, and devices for wireless communications are described. A user equipment (UE) may transmit, to a base station, a control message indicating a capability of the UE to identify and report a reciprocity parameter between downlink communications and uplink communications of a channel between the UE and the base station. In some examples, the base station may request a reciprocity report from the UE. The UE may identify a reciprocity parameter based on one or more parameters associated with an array of antennas at the UE. The reciprocity parameter may indicate a reciprocity between an uplink beam and a downlink beam, such as a degree of overlap between the uplink beam and the downlink beam. The UE may report the reciprocity parameter via a reciprocity report to the base station. In some examples, the base station may identify one or more parameters based on the reciprocity report.

The present disclosure provides a method and device in a User Equipment (UE) and a base station used for wireless communications. The UE receives first information, the first information being used to indicate a first time-domain resource and a second time-domain resource in a first sub-band, wherein the first time-domain resource is reserved for a first radio signal; performs a first access detection to determine whether to transmit the first radio signal on the first time-domain resource in the first sub-band; and transmits the first radio signal on the first time-domain resource in the first sub-band, and does not transmit any radio signal on a reserved time-domain resource in the first sub-band; or, the UE drops transmitting the first radio signal on the first time-domain resource in the first sub-band. The reserved time-domain resource is located between the first time-domain resource and the second time-domain resource in time domain.

A communication technique and a system thereof for are provided fusing a 5G communication system to support higher data rates, which is subsequent to the 4G system, with IoT technology. The disclosure may be applied to intelligent services (e.g., smart homes, smart buildings, smart cities, smart cars or connected cars, healthcare, digital education, retail business, security and safe-related services, etc.) based on 5G communication technology and IoT-related technology. A method of operating a base station in a wireless communication system includes transmitting channel feedback configuration information to a terminal; receiving channel feedback information from the terminal; and performing transmission/reception of data, based on the channel feedback information. The channel feedback information may include information indicating a state of an antenna panel of the terminal.

Methods and systems for citizens broadband radio service (CBRS) device (CBSD) interference management is described. A method for managing shared spectrum network interference includes determining, by a Citizens Broadband Radio Service (CBRS) device (CBSD) granted shared spectrum by a spectrum access system (SAS), a number of mobile devices in a defined number of regions in a cell covered by the CBSD, assigning, by the CBSD, a greater number of antennas to a cell edge region from the defined number of regions than a remaining regions in the defined number of regions, and assigning, by the CBSD, at least 8 antennas to each mobile device of a defined number of mobile devices of the number of mobile devices in the cell edge region to transmit non-overlapping and directive beams to mitigate interference at the cell edge region.

A method for configuring a sounding reference signal (SRS) resource, a base station, and a storage medium are provided. The method includes: obtaining transmit-receive port information of a user equipment (UE) based on a UE capability report; generating corresponding target configuration information based on the transmit-receive port information; and transmitting the target configuration information to the UE for configuration.

Methods and apparatus for increasing channel diversity in a MIMO system, e.g. a massive MIMO system, are described. Some selected sounding reference signal values are applied to control base station transmission for antennas, e.g., randomly or semi-randomly selected antennas, to which they do not actually correspond. The wireless terminal perceives this change as a change in channel conditions, which is subsequently reported in channel status information (CSI) to the base station. This results in increased channel diversity, which is beneficial to the base station scheduler.

The method comprises: a first terminal device receives a configuration message; the configuration message indicates M sounding reference signal (SRS) resource set groups, each SRS resource set group contains at least one SRS resource set, and M is a positive integer; each SRS resource set group corresponds to a corresponding antenna switching configuration, and the antenna switching configuration supports the first terminal device to have more than four receiving antennas. Embodiments of the present disclosure can achieve antenna switching for a terminal device having many (e.g., more than four) receiving antennas.
