摘要： Method and apparatus to rewrite BAP headers in IAB networks. The apparatus receives, from a second base station, a routing configuration indicating a mapping between a first routing ID and a second routing ID. The apparatus receives a packet with a packet header indicating the first routing ID. The apparatus determines the second routing ID based on the routing configuration mapping the first routing ID in the packet header to the second routing ID. The apparatus modifies, based on a determination of the second routing ID, the packet header to replace the first routing ID with the second routing ID. The apparatus transmits the packet based on the second routing ID.

摘要： Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from a base station, an indication of an update associated with a non-serving cell reference signal. The UE may select a first application time duration based at least in part on a determination that the non-serving cell reference signal has been tracked by the UE or a second application time duration based at least in part on a determination that the non-serving cell reference signal has not been tracked by the UE, resulting in a selected application time duration. The UE may apply the update associated with the non-serving cell reference signal after the selected application time duration. Numerous other aspects are described.

摘要： Certain aspects of the present disclosure provide techniques for wireless communication. An example method includes receiving configuration information indicating one or more configurations for an initial sidelink beamforming procedure involving one or more transmit beams, each associated with a respective antenna panel of a first UE, and performing the initial sidelink beamforming procedure based on the configuration information. Performing the initial sidelink beamforming procedure includes transmitting at least a first beamforming burst, comprising transmitting each beamforming transmission of one or more beamforming transmissions using a different respective transmit beam of the one or more transmit beams of one or more antenna panels of a first UE, monitoring for at least one response message from a second UE responding to at least one of the one or more beamforming transmissions, and taking one or more actions based on the monitoring.

摘要： Aspects of the present disclosure relate to signaling between network entities to mitigate, through management of phase shifter or amplitude controller precision, increased interference applied to a network node during uplink beamforming resulting from low phase shift or amplitude control precision. A UE transmits first uplink data in a first beam using a phase shifter or an amplitude controller configured with a first bit precision. The UE receives a message from a network entity indicating to change the first bit precision to a different, second bit precision in response to the first beam interfering with downlink communications from or to a network node. The UE afterwards transmits second uplink data in a second beam using the phase shifter or the amplitude controller reconfigured with the second bit precision. Thus, interference from lower precision phase shifters or amplitude controllers may be avoided.
