Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a first user equipment (UE) may determine, based at least in part on a channel sensing using a receive beam of the first UE, preferred resources or non-preferred resources of the first UE for a sidelink transmission by a second UE. The UE may transmit, to the second UE, inter-UE coordination (IUC) information that indicates: a transmit beam of the second UE, and the preferred resources or the non-preferred resources of the first UE, wherein the preferred resources or the non-preferred resources of the first UE are to be applied to the transmit beam of the second UE indicated in the IUC information. Numerous other aspects are described.

Abstract: Apparatus, methods, and computer-readable media for facilitating beam management enhancements in model-based channel tracking are disclosed herein. An example method for wireless communication at a first network entity includes receiving from a second network entity, a model configuration indicative of a model condition of a channel between the first network entity and the second network entity for multiple beam pairs. The example method also includes tracking a variation in a channel condition relative to the model condition of the channel based on the model configuration for each of multiple beam pairs separately in multiple tracking sessions that overlap in time. Each beam pair may include a transmission beam and a reception beam.

Abstract: Methods, systems, and devices for wireless communications are described. Generally, the described techniques at a user equipment (UE) provide for indicating multiple beams to a base station for communications with the base station after detecting a beam failure. Using these techniques, the UE may rely on multi-beam operation to recover communications with the base station. The UE may transmit a random-access preamble indicating a first beam for communications with the base station, and the UE may transmit a control element in a data channel indicating a second beam for communications with the base station. In some cases, the messages used to carry the indications of the multiple beams may be based on a type of random-access procedure used to recover communications (e.g., a contention-based random-access (CBRA) procedure, a contention-free random-access (CFRA) procedure, or a two-step random-access procedure).

Abstract: This disclosure provides systems, methods and apparatus for multi-beam operation at a user equipment (UE). In some aspects, a user equipment (UE) may transmit a beam report indicating a number of simultaneous transmit beams supported by the UE. The UE may receive a common beam indication for multiple TCI states. The UE may select at least one TCI state as an uplink component for a common beam and may communicate with a base station (BS) using the common beam. The UE may receive control signaling enabling a group-based beam reporting mode at the UE and an indication to apply a group-based beam reporting configuration for uplink beam reporting. The UE may selectively enable or disable the group-based beam reporting configuration. The UE may report multiple reference signal resource indices for multiple reference signals. The UE may transmit the reference signals using multiple spatial domain transmit filters.

Abstract: Methods, systems, and devices for wireless communications are described. In some systems, abase station may transmit multiple related downlink control information (DCI) transmissions to a user equipment (UE). The base station may transmit a first DCI in a control resource set (CORESET) and may transmit the second DCI in a configured physical downlink shared channel (PDSCH) occasion. The UE may determine the payload and the location of the second DCI for receiving the second DCI based on control signaling from the base station or based on the first DCI, or both. Accordingly, the UE may receive the first DCI and the second DCI and may transmit an uplink transmission to the base station in accordance with the first DCI and the second DCI.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment may receive a physical uplink shared channel (PUSCH) configuration that configures a first waveform and a second waveform that is different than the first waveform; and transmit, based at least in part on the PUSCH configuration, a first PUSCH repetition using one of the first waveform or the second waveform, and a second PUSCH repetition using the other one of the first waveform or the second waveform. Numerous other aspects are provided.

Abstract: Method and apparatus for semi-persistent waveform switching for uplink transmissions. The apparatus receives an indication to switch to a first waveform configuration for uplink transmission over a period of time. The apparatus transmits the uplink transmission based on the first waveform configuration during the period of time. The apparatus switches to uplink communication based on the first waveform configuration after a time period following receipt of the indication. The time period comprises a processing time to switch to the first waveform configuration. The apparatus switches to the first waveform configuration for a current BWP in response to reception of the indication.

Abstract: A method of wireless communication, by a user equipment (UE), includes determining whether conforming input has been received for each of multiple input branches to a neural network. Each input branch represents a different modality of input features to the neural network. The method also includes replacing an activation with a replacement activation for at least one neural network layer of each of the input branches associated with input determined to be non-conforming input. The method further includes predicting an output parameter based on conforming input received at each input branch and the replacement activation.

In some aspects, the method may be performed by a processor of the base station. Various aspects include determining a multicast bandwidth part (BWP) within a carrier bandwidth, sending an indication of the multicast BWP to one or more user equipment (UE) computing devices in communication with the base station, and scheduling transmission of multicast data in the multicast BWP.

Abstract: This disclosure provides systems, methods and apparatus, including computer programs encoded on computer storage media, for wireless communications. In one aspect, a user equipment (UE) may receive, from a base station, a configuration message indicating a first beam associated with an uplink control transmission and downlink control information (DCI) indicating a second beam associated with the uplink data transmission. The UE may select the first beam or the second beam based on an overlap in time between the uplink control transmission and the uplink data transmission. The base station may identify the first beam or the second beam based on the overlap between the uplink control transmission and the uplink data transmission. The UE may transmit, and a base station may receive, at least a portion of the uplink control transmission and at least a portion of the uplink data transmission using the selected first beam or second beam.
