The present disclosure relates to wireless communication methods, network devices, and terminal devices. One example method includes receiving, by a terminal device, configuration information sent by a network device, where the configuration information is used to indicate a beam sweeping type, and determining, by the terminal device, the beam sweeping type based on the configuration information.

The present disclosure relates to an electronic device, a method, and a storage medium for a wireless communication system. Various embodiments are described with respect to beam pair link. In one embodiment, the electronic device used at the base station side in the wireless communication system may comprise a processing circuitry configured to monitor status of an uplink signal; determine it necessary to adjust a first uplink beam pair link (BPL) based on the status of the uplink signal, wherein the first uplink BPL comprises a first transmitting beam at a terminal device side and a first receiving beam at the BS side; and perform operations in order to adjust the first uplink BPL.

Embodiments of this disclosure provide techniques for determining a device's beam correspondence status. As used herein, a device is considered to have “beam correspondence” when the device's TX and RX antennas satisfy a calibration criteria. In one example, a device's TX and RX antennas satisfy the calibration criteria when a difference between quality parameters corresponding to reference signals transmitted and received using corresponding TX and RX beams is less than a threshold. In another example, a device's TX and RX antennas satisfy the calibration criteria when a list of indices ranking the device's TX beams matches a list of indices ranking the device's RX beams. The lists of indices may be derived by transmitting and receiving references signals according to the devices RX and TX beams, and then generating list of indices based on quality parameters of the respective RX and TX beams.

The present disclosure comprises a method performed by a wireless device, wherein the wireless device is configured to communicate, using a set of beams, with a network node of a wireless communication system. The method comprises receiving, on one or more receive beams, one or more downlink, DL, signals from the network node. The method comprises determining one or more DL measurement parameters based on the received one or more DL signals. The method comprises determining whether the one or more DL measurement parameters satisfy a criterion. The method comprises, when it is determined that at least one of the one or more DL measurement parameters does not satisfy a criterion, indicating to the network node a beam reciprocity parameter, wherein the beam reciprocity parameter indicates a qualitative measure of one or more transmission beams of the wireless device.

Embodiments of the present disclosure provide a communication method, a terminal device and a network device. The method includes: a terminal device determines beam correspondence information, where the beam correspondence information indicates a beam correspondence between an uplink transmitting beam and a downlink receiving beam of the terminal device; and the terminal device transmits the beam correspondence information to a network device. The communication method according to embodiments of the present disclosure can alleviate the burden on devices.

Techniques for selecting the number of sounding reference signal (SRS) resources to be used by a user equipment (UE) operating in a wireless communications system are provided. The UE determines a degree of partial beam correspondence of the UE and compares the degree to a threshold amount of partial beam correspondence support of the UE. In response to the comparison, UE selects a number of sounding reference signal (SRS) resources to request from a network node and sends a SRS resource request message to the network node to request the selected number of SRS resources.

Provided is a communication method, and a user equipment and a network equipment performing the communication method, communication method performed by a user equipment, comprising: measuring downlink signals; determining a downlink receiving beam and a first uplink transmitting beam according to a measurement result for the downlink signals; generating indication information for beam correspondence according to the measurement result for the downlink signals and/or preset user equipment information, and sending, to a network equipment, the generated indication information for beam correspondence with the determined first uplink transmitting beam; performing uplink transmitting beam sweeping according to a resource for performing uplink transmitting beam sweeping allocated by the network equipment, when an indication to enable uplink transmitting beam sweeping of the user equipment sent by the network equipment is received; receiving, with the determined downlink receiving beam, the measurement result of the uplink transmitting beam sweeping fed back by the network equipment, and determining a second uplink transmitting beam according to the measurement result of the uplink transmitting beam sweeping; transmitting an uplink signal with the determined second uplink transmitting beam.

A first wireless communication device, such as a base station, may include separate transmit and receive antenna arrays. The separation between the transmit and receive antenna arrays may cause a direction of a transmit beam formed at the transmit antenna array to be different from a direction of a receive beam formed at the receive antenna array. The transmit and receive beams may be formed for communication with a second wireless communication device, such as a user equipment (UE). The described aspects enable the first wireless communication device to monitor a difference between a first direction of the transmit beam and a second direction of the receive beam. The first wireless communication device may transmit an indication of a beam correspondence failure to the second wireless communication device when the difference between the first and second directions is greater than or equal to a beam correspondence threshold.

The present application is applied to the communications field and provides a method for obtaining a location of UE, and an apparatus. The method includes: sending, by a base station, at least one beam, where each beam includes first beam identity information, the first beam identity information is used to uniquely identify the beam, and the beam is received by UE that is in coverage of the beam; receiving, by the base station, second beam identity information sent by the UE, and the second beam identity information is used to indicate a beam on which the UE resides; and communicating, by the base station, with the UE according to the beam which the UE resides second beam identity information sent by the UE. By means of the apparatus and the method of embodiments of the present application, location information of UE can be obtained in a millimetric wave scenario.

The present disclosure relates to wireless communication methods, network devices, and terminal devices. One example method includes receiving, by a terminal device, configuration information sent by a network device, where the configuration information is used to indicate a beam sweeping type, and determining, by the terminal device, the beam sweeping type based on the configuration information.
