UPLINK TIMING MANAGEMENT IN COMMUNICATIONS SYSTEMS
Methods, systems, and devices for wireless communication at a user equipment (UE) are described. A UE may receive, at a source cell served by a network entity, signaling that triggers a handover to a target cell. The UE may also receive a first set of parameters associated with the target cell, the first set of parameters indicating that the target cell is served by the network entity. The UE may then transmit, to the target cell, an uplink communication in accordance with a timing advance value for the target cell. In some examples, the timing advance value for the target cell may be derived using a timing advance value for the source cell based on the target cell being served by the network entity.
MULTILINK DEVICE FOR SWITCHING OPERATION
Switching operations are described that provide greater reliability for multilink operations between an access point multilink device (AP MLD) and a non-AP MLD in a wireless communications network. The AP MLD announces that the AP MLD switches one of the multilinks necessary for the multilink operation. The non-AP MLD determines whether an AP operating on a switching link has resumed basic service set (BSS) operation on a target channel.

WIRELESS DEVICE, RADIO NETWORK NODE, AND METHODS PERFORMED THEREIN FOR COMMUNICATING IN A WIRELESS COMMUNICATION NETWORK
Some embodiments herein relate to a method performed by a wireless device (10) for handling communication of the wireless device (10) in a wireless communication network (1), wherein a first radio network node serves the wireless device (10) and the wireless communication network (1) further comprises a second radio network node (13). The wireless device receives a handover command from the first radio network node (12) indicating a handover to a cell served by the second radio network node (13), the handover command comprises a beam indication, such as a threshold, controlling which beam of the cell to select by the wireless device (10). The wireless device (10) further selects a beam of the cell based on at least the beam indication.

Methods and related devices for channel state information (CSI) reporting for bandwidth part (BWP) switch operation
A method performed by a BS for configuring CSI reporting is provided. The method includes transmitting a CSI reporting configuration to a UE on a first BWP; transmitting a first BWP switch indication to the UE on the first BWP, the first BWP switch indication being used to request the UE to switch to a second BWP; transmitting a second BWP switch indication to the UE after the UE switches from the first BWP to the second BWP, the second BWP switch indication being used to request the UE to switch back to the first BWP; and receiving a CSI report from the UE based on the CSI reporting configuration, without providing any CSI reporting activation command to the UE after the UE switches back to the first BWP according to the second BWP switch indication. A BS using the same is also provided.
BEAM FAILURE RECOVERY METHOD, DEVICE, AND SYSTEM
Embodiments of this application provide example beam failure recovery methods, example devices, and example systems to perform beam failure recovery. In one example method, a terminal device receives configuration information. The terminal device can determine M beam failure detection resource groups and N candidate beam resource groups based on the configuration information, where M and N are positive integers greater than 1. In response to determining that quality of each beam failure detection resource in any of the M beam failure detection resource groups is lower than a first threshold, the terminal device can determine, from a candidate beam resource group that is associated with the beam failure detection resource group and that is in the N candidate beam resource groups, one or more candidate beam resources whose quality is higher than a second threshold, and send first indication information.

METHODS AND APPARATUS FOR SUPPORTING BAND STEERING AND/OR CHANNEL STEERING IN WIFI COMMUNICATIONS SYSTEMS
Methods and apparatus for supporting band steering and/or channel steering in wireless communications systems, e.g. WiFi communications systems, are described. An access point aggregates information, e.g., from messages being communicated between the access point and client devices being serviced by the access point, and generates reports. The generated reports are communicated to a control device, e.g. a radio resource management (RRM) device. In some embodiments, generated reports include one or more of: i) message header information, e.g. resource unit (RU) allocation and/or use information and/or BSS color information, ii) collision reports, iii) received signal strength indicator (RSSI) reports, signal to noise ratio (SNR) reports, iv) interference reports; v) power information; vi) access point measurement information; and vii) access point control information. The control device uses the received reports from APs, in making bandsteering decisions with regard to individual client devices, and channel change decisions with regard to access points.
