According to various embodiments, a method of operating a network may include transmitting to a first user equipment (UE) connected to the network, at least one transmission signal for downlink traffic corresponding to the first UE based on a first direction, transmitting a plurality of synchronization signal blocks (SSBs) configured by the network, based on a plurality of directions corresponding respectively to the plurality of SSBs, and identifying a degree of overlap between each of the plurality of directions corresponding respectively to the plurality of SSBs and the first direction.

Methods, systems, and devices for wireless communications at a user equipment (UE) are described. Aspects of the described techniques may include the user equipment measuring signal aspects for a plurality of respective receive beams for receiving communications associated with a synchronization signal block transmitted by a base station on a transmit beam. From the measured signal aspects, the UE may determine that a receive beam from the plurality of receive beams is a preferred beam for receipt of communications from the base station transmitted on the transmit beam. With the determined preferred beam, the UE may initiate a beam-sweeping procedure to re-measure the plurality of UE receive beams, where the UE measures the first UE receive beam before measuring others of the plurality of UE receive beams.

A technique for rotating one or more multi-sector antennas mounted on unmanned aircrafts of a radio access network, RAN, is described. Each of the multi-sector antennas comprises multiple sectors. The multiple sectors of each of the multi-sector antennas are configured to provide radio access to radio devices in different azimuthal directions that are changeable relative to the aircraft and fixed relative to each other when rotating the respective one of the multi-sector antennas. As to a method aspect of the technique, the at least one or each of the aircrafts of the RAN determines signal strengths of radio signals exchanged between a first radio device and at least two of the multiple sectors of the multi-sector antenna mounted on the respective one of the aircrafts Based on the determined signal strengths, a first azimuthal direction is computed for providing radio access to the first radio device. A first sector of the multiple sectors of the multi-sector antenna mounted on the respective one of the aircrafts is rotated in the computed first azimuthal direction.

A method and apparatus for triggering a user equipment beam reconfiguration procedure are disclosed. The method comprises: receiving, at a user equipment, channel parameters relating an uplink channel and a downlink channel; determining, at the user equipment, from the channel parameters whether there is a mismatch in uplink channel and downlink channel performance and, if so; triggering, at the user equipment, a user equipment beam reconfiguration procedure.

A beam management method performed by a moving backhaul hub may comprise: calculating, based on location information at a first time, a first separation distance between the moving backhaul hub and a moving backhaul terminal, a first azimuth angle to which a beam of the moving backhaul hub is directed, and a first elevation angle in which the beam of the moving backhaul hub is directed; determining an operation mode of the moving backhaul terminal using the first separation distance, the first azimuth angle, and/or the first elevation angle; determining whether to transmit a beam search command message to the moving backhaul terminal based on the operation mode of the moving backhaul terminal; and transmitting signals to the moving backhaul terminal in consideration of the operation mode when the beam search command message is transmitted to the moving backhaul terminal.

A wireless base station, via a first wireless beam in a beamforming codebook, transmits communications to multiple communication devices. In one implementation, the wireless base station receives respective channel matrix information from each of the multiple communication devices. The channel matrix information indicates weight coefficients applied to respective receiver antenna hardware to receive the communications. Alternatively, when reciprocity holds, the wireless base station can be configured to generate the channel matrix information based on observation of receiving communications from the one or more communication devices. Via the channel matrix information, a communication management resource associated with the wireless base station adjusts beamforming settings of the first wireless beam to best support communications with the communication devices over the first wireless beam. The communication management resource dynamically updates the beamforming codebook such that a corresponding wireless beam is angularly adjusted towards a centroid of the communication devices.

A base station device (100) transmits, to a terminal device (200), repetition information instructing repetition transmission of a signal in an uplink and beam information instructing a beam to be used for the repetition transmission in association with each other.

This disclosure provides a beam management method and apparatus, to quickly implement beam alignment. The beam management method is applied to a first device and includes: obtaining a first reference signal sent by a second device based on a first set beam, and determining a first beam based thereon such that a signal quality of the first reference signal obtained by the first device based on the first beam is the best; and sending a second reference signal to the second device based on the first beam, where the second reference signal is used to determine a second beam of the second device, and a signal quality of the second reference signal obtained by the second device based on the second beam is the same as that of the first reference signal obtained by the first device based on the first beam.

A user equipment (UE) device may communicate with an access point (AP) at greater than 100 GHz via a reconfigurable intelligent surface. The UE may select tracking beams based on sensor data. The UE may instruct the RIS to sweep over the tracking beams while the UE gathers performance metric data. The UE may identify a serving beam based on the performance metric data. The UE may control the RIS to form the serving beam to reflect wireless data between the AP and the UE. Using the UE to intelligently select tracking beams based on sensor data may greatly reduce the amount of time required to track the UE device as it moves relative to sweeping over all formable signal beams, thereby reducing latency and minimizing disruptions in wireless data transfer between the UE device and the AP.

This application provides communication methods and apparatuses. One method includes: accessing, by a terminal device, an access network device by performing first random access in a radio resource control inactive (RRC inactive) state, and receiving, by the terminal device by using a first receive beam for downlink transmission of the first random access, downlink control information (DCI) transmitted by the access network device.
