Abstract: Methods, systems, and devices for wireless communications are described. The described techniques provide for training a beam for multiple component carriers (CCs) for concurrent communications in a wireless communications system associated with limited user equipment (UE) capabilities. The UE receives, via a first receive beam, a first reference signal on a group of CCs over a first symbol. The UE also receives, via a second receive beam, a second reference signal on the group of CCs over a second symbol. The UE selects a receive beam for a subsequent communication based on determining a value of a parameter for each of the first and the second receive beam.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may transmit, to a base station, information indicating a Layer 1 signal to interference plus noise ratio (L1-SINR) measurement capability of the UE. The UE may receive, from the base station, a reference signal carried on one or more resources based at least in part on the L1-SINR measurement capability. Numerous other aspects are provided.

Abstract: Methods, systems, and devices for wireless communications are described. In one example, a first user equipment (UE) identifies a trigger condition associated with a first communication link with a base station and establishes a second communication link with a second UE. The UE may transmit a relay request to the second UE based on the trigger condition, wherein the relay request instructs the second UE to relay communications for the first UE. The first UE communicates with the base station via the second communication link. In another example, a base station establishes communication links with a first and second UE. The base station receives a data forwarding request that instructs the base station to use the second UE to relay communications between it and the first UE. The base station communicates with the first UE via the second communication link based at least in part on the relay request.

Abstract: Certain aspects of the present disclosure provide methods and apparatus for selecting numerology for sidelink synchronization signals. When one or more user equipment (UE) are in various modes of network signaling with a base station (BS), a first UE may determine a mode of network signaling between the first UE and the BS. The UE may then determine a first numerology based on the mode, and receive, from a second UE, a sidelink signal having a subcarrier spacing corresponding to the first numerology.

Abstract: Methods, systems, and devices for wireless communications are described. In some examples, a first UE may receive an indication of first resources from a second UE. In some examples, the second UE may be a UE configured to receive a transmission from a third UE over the first resources. In some such examples, the first UE may transmit, to a fourth UE, a sidelink transmission over available resources that exclude the first resources. Additionally, or alternatively, the second UE may be a UE that received sidelink control information from the third UE indicating the resources for transmission by the third UE to a fourth UE. In some such examples, the first UE may transmit, to the second UE, a sidelink transmission over available resources that exclude the first resources.

Abstract: Methods, systems, and devices for wireless communications that support power control in full duplex communication are described. In some wireless communications systems, a user equipment (UE) may experience antenna isolation for communication of downlink and uplink data traffic. Based on the antenna isolation, the UE may realize an increased channel capacity for full-duplex communication. As part of the full-duplex communication, the UE may identify characteristics of a potential downlink signal on formatted slots of the channel. The UE may determine an uplink transmit power control configured to account for the characteristics. The determination may include a configured transmit power control for beamformed signaling at the UE, and may be based on signal reception quality for potential downlink transmissions. Based on the determination, the UE may either perform uplink transmission on a resource block allocation of the formatted slots or forgo uplink transmission.

Abstract: Some aspects provide an apparatus for wireless communication, in accordance with some aspects of the present disclosure. The apparatus generally includes at least one processor, and at least one memory communicatively coupled with the at least one processor and storing processor-readable code. The processor-readable code, when executed by the at least one processor, may be configured to transmit a packet including at least one medium access control-control element (MAC-CE), receive hybrid automatic request (HARQ) signaling indicating whether the packet was decoded successfully, determine, in response to the HARQ signaling, whether to retransmit the at least one MAC-CE or transmit at least one other MAC-CE based on whether the packet comprises data, and transmit another packet having the at least one MAC-CE or the at least one other MAC-CE based on the determination.

Abstract: Methods, systems, and devices for wireless communications are described. Sidelink UEs may be configured with a synchronization reference signal that may be used by the UEs to synchronize time and frequency resources. A first and second UE may perform a beam sweeping procedure to identify transmit and receive beams to use for communications between the UEs. A synchronization reference signal procedure may be initiated and the first UE may receive a sidelink synchronization reference signal from the second UE using the established receive beam. The UEs may align time and frequency resources for communications between the UEs and the UEs may communicate via the sidelink channel based on the time synchronization, frequency synchronization, or both, determined using the sidelink synchronization signal. In some cases, a sidelink UE may receive multiple synchronization reference signals from multiple sidelink UEs simultaneously, where each synchronization reference signal may include a UE identifier.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a wireless communication device may transmit an announcement that indicates a plurality of future resource reservations. The wireless communication device may transmit multiple sets of announcements that indicate one or more reservations and may vary the transmission frequency thereof based on proximity to the communications. The wireless communication device may transmit an announcement that indicates a future communication and a cancellation indication that indicates a cancellation of the communication. The wireless communication device may transmit a preemption indication that indicates that resources reserved for an announced future communication have been preempted for another communication. Numerous other aspects are described.
