Abstract: Aspects of the present disclosure provide techniques for beam failure detection and related timing determinations, such as for applying a default beam after beam failure recovery response (BFRR) message. A method by a user equipment (UE) may include detecting failure of a beam associated with a first cell. The detecting can include performing beam failure detection (BFD) of a beam pair link (BPL) associated with the first cell (e.g., secondary cell (Scell)). The first cell can be in carrier aggregation (CA) with a second cell. The UE may send a beam failure recovery request (BFRQ) message on a second cell (e.g., a primary cell (Pcell)). The BFRQ message can include a candidate recovery beam for the first cell. The UE can receive a BFRR message on the second cell and determine a duration from reception of the BFRR message until using a default beam for communications on the first cell.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment may determine a message type for a random access message associated with a two-step random access channel procedure. The message type may be either a first message type or a second message type that is different from the second message type. The message type may be determined based at least in part on whether a signal strength satisfies a signal strength threshold. The user equipment may transmit the random access message based at least in part on the determined message type. Numerous other aspects are provided.

Abstract: Methods, systems, and devices for wireless communications are described. The described techniques relate to improved methods, systems, devices, and apparatuses that support beam preference feedback for data transmissions. Generally, the described techniques provide for wireless communications at a user equipment (UE), that may perform a measurement of one or more reference signals from a base station. The UE may transmit to the base station an indication of a beam preference for communicating with the base station based on the measurement of the one or more reference signals. The UE may receive, based on the indication of the beam preference, downlink control information from the base station, the downlink control information including an indication of a beam for a data transmission. The UE may perform or receive the data transmission using the indicated beam.

Abstract: Methods, systems, and devices for wireless communications are described. A first wireless device may transmit reference signals via a first antenna array of the first wireless device. The first wireless device may perform, according to a reporting configuration for self-interference at the first wireless device, a set of measurements on the reference signals received at a second antenna array of the first wireless device. The first wireless device may determine a priority associated with transmission of measurement reports associated with self-interference at the first wireless device. The first wireless device may then transmit, to a second wireless device and according to the reporting configuration, a measurement report including an indication of self-interference for full-duplex communications at the first wireless device that is based on performing the set of measurements on the reference signals, where the measurement report is transmitted in accordance with the determined priority.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from a base station, a configuration for periodic communications. The UE may determine that the UE has successfully received a respective initial transmission in each transmission cycle of a threshold number of transmission cycles associated with the periodic communications. The UE may deactivate repetitions in one or more transmission cycles based at least in part on the determination. Numerous other aspects are provided.

Abstract: Aspects described herein relate to report of timing difference for different synchronization signal blocks (SSBs) in fifth generation new radio (5G NR). In an example, the aspects may include receiving, from a network entity, a message indicating at least two SSBs, wherein a first of the two SSBs is associated with a first remote radio header (RRH) and a second of the two SSBs is associated with a second RRH; determining a received timing difference for at least the two SSBs; and transmitting the timing difference for at least the two SSBs to the network entity.

Abstract: Methods, systems, and devices for wireless communications are described. In some systems, a user equipment (UE) may perform a dual active link handover procedure from a source base station to a target base station. During the dual active link handover procedure, the UE may have connections to both of the base stations concurrently. In such cases, transmission opportunities for communicating with the base stations may conflict. To handle conflicting transmission opportunities, the UE may drop a monitoring occasion or a packet reception for a base station based on prioritization rules. In some cases, to mitigate packet losses, the base station may configure re-transmissions or slot aggregation to provide the UE with additional opportunities to receive a packet. Additionally or alternatively, the UE may transmit a notification message to a base station indicating dropped monitoring occasions or packets.

The apparatus may transmit, to a base station, an indication including a RLM capability. The apparatus may receive, from the base station, a RLM RS configuration from the UE based on the indication. The apparatus determines the RLM RS configuration for the UE, based on the RLM RS configuration received from the base station.

Abstract: Methods, systems, and devices for wireless communications are described. In some examples, a user equipment (UE) may transmit, to a base station, indications of capability levels of the UE. Each capability level of the UE may correspond to a respective beam group supported by the UE in a UE cooperation mode. The UE may include sets of antenna components at the UE or distributed across the UE and on or more other devices in the UE cooperation mode. Each set of antenna components may form the respective beam groups. The base station may receive the capability levels of the UE and select an activated capability level for the UE from the reported capability levels. The base station may signal the activated capability level to the UE and perform communications with the UE according to the activated capability level and the corresponding beam group.

Abstract: Aspects described herein relate to beam sweep based semi-persistent signaling (SPS) or configured grant (CG) activation. In one aspect, a network entity may determine a beam sweep pattern for at least one of a SPS based downlink periodic transmission, an uplink control transmission for the SPS based downlink periodic transmission, or a CG based uplink periodic transmission. The network entity may further transmit an indication including the beam sweep pattern to a user equipment (UE). In another aspect, a UE may receive a beam sweep pattern for at least one of a SPS based downlink periodic transmission, an uplink control transmission for the SPS based downlink periodic transmission, or a CG based uplink periodic transmission from a network entity.
