Abstract: Aspects of the disclosure relate to a multi-antenna wireless user equipment (UE) calculating a covariance matrix corresponding to a covariance of signals received from each of its antennas. The UE further calculates the eigenvectors of the covariance matrix, and transmits feedback including information corresponding to the eigenvectors. Based on this information, a base station can determine to alter a number of beams for transmitting information to the UE, efficiently improving the reliability of transmission to the UE. Other aspects, embodiments, and features are also claimed and described.

Abstract: Apparatuses and methods for wireless communication are provided. In an aspect, a user equipment (UE) receives a DCI from a base station, the DCI including an update to a periodically-occurring scheduling, where an absolute time for the update to take effect is specified in an RRC configuration of the DCI. The UE applies the update to the periodically-occurring scheduling for communications of the UE beginning at and following the absolute time. In another aspect, the UE receives at least one downlink communication that updates a plurality of SPS or CG parameters. The UE determines an action time for the update to take effect for each parameter, where the action time is a function of a type of each parameter. The UE applies the update to each parameter for communications of the UE beginning at and following a respective action time.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a network node may apply a crest factor reduction (CFR) to an input signal to generate an output signal, the applying the CFR to the input signal including applying a shaping filter that distributes a first portion of CFR noise within a transmission frequency band of the output signal and a second portion of the CFR noise in at least one air interface resource that is outside of the transmission frequency band of the output signal. The network node may transmit the output signal. Numerous other aspects are described.

Abstract: Methods, systems, and devices for wireless communications are described. Generally, a user equipment (UE) may monitor for semi-persistent scheduling (SPS) transmissions and generate SPS hybrid automatic repeat request (HARQ) bits scheduled for transmission to the base station in a set of uplink symbols. However, a collision may occur during transmission if a physical uplink control channel (PUCCH) carrying the SPS HARQ bits overlaps with downlink symbols. The UE may defer all SPS HARQ bits from collided PUCCHs to a next available PUCCH resource. In some examples, the UE may distribute deferred HARQ bits across multiple available PUCCH resources. The UE may distribute the deferred HARQ bits evenly across the next available PUCCH resources, or the UE may distribute the deferred HARQ bits unevenly according to a pattern. In some examples, the base station may indicate (e.g., via a downlink control information (DCI) message) a deferment pattern to the UE.
