Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may detect a beam failure associated with a cell of a plurality of cells. The UE may selectively transmit a beam failure recovery request (BFRQ) communication for the cell based at least in part on a determination of whether a threshold time period has elapsed since a previous BFRQ communication was transmitted for the cell or another cell of the plurality of cells. Numerous other aspects are provided.

Abstract: Methods, systems, and devices for wireless communications are described. A set of user equipments (UEs) may communicate with each other on communication links using data resources from a pool of shared resources. The UEs may be configured to multiplex control resources with data resources of a shared resource pool. In some cases, a UE may communicate, in control resources, control signaling to reserve data resources of a shared resource pool. After transmitting the request, the UE may communicate data in one or more data resources. The UE may communicate the data using transmission components while concurrently processing control signaling using other components.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a first user equipment (UE) may identify a first set of resources for an access link communication between the first UE and a base station. The UE may identify a second set of resources for a sidelink communication between the first UE and a second UE. The UE may identify a scheduling conflict between the first set of resources for the access link communication and the second set of resources for the sidelink communication. The UE may drop at least a portion of the first set of resources for the access link communication or the second set of resources for the sidelink communication based at least in part on the identification of the scheduling conflict and a prioritization rule. Numerous other aspects are provided.

Abstract: Methods, systems, and devices for wireless communications are described. Generally, the described techniques provide for determining shared resources associated with one or more user equipments (UEs) for sidelink communications, including control resources and data resources. A first UE may determine a first set of control resources in a first frequency band corresponding to a first group of UEs including the first UE. The first UE may transmit a sidelink request to reserve a subset of data resources to a second UE in the first group of UEs. The first UE may monitor for one or more sidelink responses indicating a positive sidelink response to the sidelink request, a negative sidelink response to the sidelink request, or both. The first UE may determine, based on monitoring for the one or more sidelink responses, whether to transmit a sidelink confirmation indicating a reservation of the data resources to the second UE.

Abstract: Apparatus, methods, and computer-readable media for facilitating a soft in-coverage/out-of-coverage indication for sidelink communications are disclosed herein. An example method for wireless communication at a wireless device includes determining a coverage state with reference to a cell for a timing reference. In some examples, the coverage state may be determined from among a set of states including an in-coverage state, an out-of-coverage state, and at least one additional coverage state. The example method also includes broadcasting a state indicator based on the coverage state determined by the wireless device.

Abstract: Certain aspects of the present disclosure provide techniques for managing beam failure recovery operations. A method that may be performed by a user equipment (UE) generally includes performing beam failure detection (BFD) of a beam pair link (BPL) associated with a secondary cell (Scell) of a base station (BS), sending a beam failure recovery request (BFRQ) message in another cell of the BS, the BFRQ message including an indication of a candidate recovery beam for the Scell, and starting a timer based on sending the BFRQ.

Abstract: Certain aspects of the present disclosure relate to assisting communications with low data payloads with relay nodes. An example method generally includes forming a first cluster with a first wireless node and one or more second wireless nodes, wherein each of the second wireless nodes has a low data rate demand relative to a system bandwidth. The method also includes determining to serve as a relay node for the first cluster, generating a first set of packets for uplink transmission to a base station, receiving a second set of packets from the one or more second wireless nodes, combining the first set of packets and the second set of packets into an uplink payload based on the determination, and transmitting, to the base station, the uplink payload based on the determination.

Abstract: Methods, systems, and devices for wireless communications are described. A base station may transmit a first downlink grant (e.g., a PDCCH transmission) for a first data transmission (e.g., a PDSCH transmission) over a first component carrier; the first data transmission over a second component carrier; and a second downlink grant (e.g., another PDCCH transmission) for a second data transmission (e.g., another PDSCH transmission) over the second component carrier. A user equipment (UE) receives the first data transmission over a first beam and may use the first beam for receiving the second data transmission. Additionally or alternatively, the UE may receive a configuration message indicating a set of TCI states for downlink data transmissions to the UE; identify one or more reference signals monitor for beam failure detection (BFD), identify one or more BFD beams, monitor the identified one or more reference signals; and selectively trigger a beam failure reporting procedure.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may transmit a beam failure recovery scheduling request (BFR-SR) to a primary cell or a primary secondary cell base station based at least in part on detecting a beam failure associated with a secondary cell (SCell) link between the UE and an SCell base station. The UE may start a timer based at least in part on transmitting the BFR-SR. The UE may retransmit the BFR-SR based at least in part on the timer expiring prior to the UE receiving a response to acknowledge the BFR-SR and schedule transmission of a medium access control (MAC) control element (MAC-CE) including information to recover from the beam failure and/or the timer expiring prior to the UE transmitting the MAC-CE. Numerous other aspects are provided.
