    Abstract: A user equipment (UE) is configured to establish a connection to a base station, wherein the base station configures the UE with a first beam corresponding to a first transmission reception point (TRP) and a second beam corresponding to a second TRP, wherein the first and second beam are in frequency range 2 (FR2) and wherein the UE does not support simultaneous reception of multiple beams in FR2, detect a beam failure during a beam failure detection (BFD) evaluation period, identify one or more candidate beams during a candidate beam detection (CBD) evaluation period and transmit a beam failure recovery (BFR) request to the base station.

    Abstract: Approaches for performing Physical Uplink Shared Channel (PUSCH) transmissions include receiving, by a user equipment (UE) from a base station, an indicator of a plurality of precoders corresponding to M Physical Uplink Shared Channel (PUSCH) repetitions, wherein M is an integer. A plurality of precoders corresponding to two or more of the M PUSCH repetitions are indicated. The UE configures the plurality of precoders based on the indicator and transmits one or more of the M Physical Uplink Shared Channel (PUSCH) repetitions corresponding to one or more of the plurality of precoders. The indicator can be provided in higher layer signaling. One or more transmission rank indicator (TRIs) and transmission precoder matrix indicators (TPMIs) for the M PUSCH repetitions can be provided. The indicator can be provided in a scheduling downlink control indicator (DCI) communication. The indicator can also be provided within N sounding reference signal (SRS) resource indicator(s) (SRIs) of the scheduling DCI.

    Abstract: In a general aspect, a user equipment (UE) in a cellular communications network receives a first Synchronization Signal Block (SSB) corresponding to a first cell of the cellular communications network, and a second SSB corresponding to a second cell of the cellular communications network. The UE clarifies a first cell identifier (ID) of the first cell. The UE clarifies a second cell ID of the second cell. The UE determines an SSB measurement accuracy value using the first cell ID and the second cell ID.

    Abstract: Apparatuses, systems, and methods for SRS antenna switching. A UE may transmit, to a base station, a capability message indicating an antenna configuration associated with SRS antenna switching e.g., via as RRC signaling. The capability message may indicate at least one of (and/or one or more of) a one transmit point (1T) and six receive point (6R) SRS resource set configuration, a 1T8R SRS resource set configuration, a 2T6R SRS resource set configuration, a 2T8R SRS resource set configuration, and/or a 4T8R SRS resource set configuration. The UE may receive, from the base station, a configuration message, e.g., via RRC signaling. The configuration message may indicate an SRS antenna switching configuration based, at least in part, on the capability message. The UE may transmit, to the base station, one or more SRSs, e.g., according to the SRS antenna switching configuration.
