Aspects of the present disclosure provide a method for wireless communication at a user equipment (UE). The method includes selecting, for each of a plurality of periodic search opportunities, one receive beam of a plurality of receive beams for receiving at least one synchronization signal. The plurality of periodic search opportunities includes a plurality of regular search opportunities and a plurality of prioritized search opportunities. The plurality of receive beams includes at least one prioritized receive beam and at least one additional receive beam. The selecting includes selecting from the at least one prioritized receive beam for each of the plurality of prioritized search opportunities; and selecting from the plurality of receive beams for each of the plurality of regular search opportunities. The method further includes receiving, at each of the plurality of periodic search opportunities, the corresponding at least one synchronization signal using the corresponding selected receive beam.

A base station switches, for a wireless device, from a first downlink bandwidth part (BWP) to a second downlink BWP identified with a downlink BWP index. The base station, switches, for the wireless device and based on the second downlink BWP being configured with beam failure recovery (BFR) for the wireless device, from a first uplink BWP to a second uplink BWP identified with an uplink BWP index that is the same as the downlink BWP index. The base station switches, for the wireless device, from the second downlink BWP to a third downlink BWP. Based on the third downlink BWP not being configured with BFR, the base station keeps the second uplink BWP as an active uplink BWP for the wireless device.

A method and apparatus for non-terrestrial network beam switching is provided. A non-terrestrial network base station includes a transmitter configured to transmit downlink data to user equipment and a receiver configured to receive uplink data from the user equipment. A channel bandwidth of the non-terrestrial network base station is divided into a plurality of bandwidth parts respectively corresponding to a plurality of geographic areas, and each bandwidth part is respectively associated with a satellite beam. When the user equipment is located in a first geographic area, the transmitter transmits the downlink data to the user equipment over a corresponding first bandwidth part. After the user equipment transitions from the first geographic area to a second geographic area, the transmitter transmits the downlink data to the user equipment over a corresponding second bandwidth part of the plurality of bandwidth parts.

An Information Handling System (IHS) includes executable instructions for establishing a communication session conveyed through a first band provided by an access point having a multi-band simultaneous protocol. During the communication session, when the instructions determine that the communication session should be conveyed through a second band provided by the access point (AP), they transmit one or more communication session parameters associated with the communication session to the access point to prepare a second band MAC component of a second band provided by the AP to convey the communication session, and transmit the communication session parameters to a second band MAC component of the IHS to prepare the second band MAC component of the IHS to convey the communication session over the second band. After transmitting the communication session parameters to the second band MAC component of the IHS and the second band MAC component of the AP, the instructions then initiate a switch over to the second band.

A beam switching method includes: a network device sending a network device beam switching information to a terminal according to position information and channel measurement information of the terminal, where the beam switching information includes information of a beam switching requirement and/or a destination beam.

A method includes composing, after a beam failure has been detected by a user equipment on a resource provided by a first serving cell of the user equipment, beam recovery signaling, the beam recovery signaling indicating at least one candidate beam to be used in beam failure recovery and transmitting, to a network entity, the beam recovery signaling on a resource provided by a second serving cell.

Embodiments provide a beam switching method and a related device. Under the method a first subframe sent by a base station by using a first beam can be received by a terminal device. The first subframe includes first-order downlink control information and second-order downlink control information. The terminal device can search for the second-order downlink control information based on the first-order downlink control information. The first-order downlink control information includes location indication information of the second-order downlink control information in the first subframe. The terminal device can switch from the first beam to a second beam based on the found second-order downlink control information to receive a second subframe. The downlink control information includes a switching indication field of the second beam. In this way, flexibility of beam switching is improved, load balancing of a control channel is implemented, and a latency of beam switching is reduced.
