Abstract: Aspects of the present disclosure provide methods and apparatus for applying transmitter beamforming for self-interference cancellation. According to aspects, a method generally includes in an acquisition phase, iteratively acquiring received power measurements for different receive chains for transmissions sent via a plurality of beam directions; estimating a self-interference subspace eigenvector based, at least in part, on the received power measurements; based on the estimated self-interference subspace eigenvector, performing a local search of a nullspace to identify a filtering eigenvector; and applying the filtering eigenvector to one or more transmission chains to cancel self-interference on one or more receive chains.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from a network node, configuration information for access point communications, wherein the configuration information indicates at least one of a triggering condition or a reporting condition, wherein the triggering condition is a condition for transmitting a control frame to an access point. The UE may receive, from the access point, an access point beacon. The UE may transmit, to the access point, a robust action frame. Numerous other aspects are described.

Abstract: Certain aspects of the present disclosure provide techniques for synchronization signal block (SSB) based spectrum coexistence. An example method, performed at a network entity of a first radio access technology (RAT) network, includes outputting, for transmission, signaling configuring a user equipment (UE) to perform a search and measurement procedure associated with signals on frequency bands that are shared between the first RAT network and a second RAT network, obtaining, from the UE, a report with information indicating results of the search and measurement procedure, and performing one or more actions to mitigate interference based on the information.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a message that includes an indication that a transmission configuration indicator (TCI) state switch for the UE is to be across a serving remote radio head (RRH) and a next RRH. The UE may adjust a tracking of the UE with respect to the serving RRH and the next RRH based at least in part on the indication. Numerous other aspects are described.

Abstract: Certain aspects of the present disclosure provide techniques for improving time division duplexing (TDD) downlink-uplink configuration for new radio (NR) operation with large timing advancements (TAs). An example method by a user equipment (UE) includes transmitting, to a network entity, an indication of a timing advance (TA) value; receiving, from the network entity, information indicating a set of downlink slots of a time division duplexing (TDD) pattern that is dynamically restricted from being scheduled for the UE, wherein the set of downlink slots is based on the TA value; and receiving, from the network entity, downlink transmissions in downlink slots of the TDD pattern except in downlink slots included in the set of downlink slots.

Abstract: Waveforms for wireless communication are shaped asymmetrically according to a complex-valued weighted overlap/add (WOLA) filter. A wireless communication device generates a waveform corresponding to a carrier. The device determines whether neighboring carriers are being used for wireless communication. If one neighboring carrier is occupied and the other is unoccupied, the wireless communication device applies the asymmetrical filter to the waveform such that out-of-band signals which may interfere with the occupied carrier are suppressed to a greater extent than out-of-band signals potentially present in or around the unoccupied carrier. The wireless communication device then transmits the asymmetrically shaped waveform to maximize interference reduction and signal quality.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may detect whether a reference signal is present in a channel at a time instance at which the reference signal is expected. The UE may selectively gate processing of the reference signal based on detecting whether the reference signal is present in the channel. Numerous other aspects are described.
