Abstract: Various aspects of the present disclosure generally relate to wireless communication. A source user equipment (UE) may transmit, to a relay UE, information identifying that the relay UE is one of a plurality of relay UEs selected for cooperative relaying of a communication from the source UE to a destination UE. A channel between the source UE and the relay UE may be one of a plurality of channels comprising a channel between the source UE and each relay UE of the plurality of relay UEs. The plurality of relay UEs may be selected based at least in part on a degree of correlation of the channel between the source UE and the relay UE with at least one other channel of the plurality of channels. The UE may transmit the communication to the plurality of relay UEs for cooperative relaying to the destination UE. Numerous other aspects are described.

Abstract: Aspects are provided for HARQ feedback and retransmission procedures for cooperative relaying in sidelink networks. A relay attempts to decode sidelink data received from a source for relay to a destination. The relay may combine LLRs for the sidelink data and for a retransmission of the sidelink data. The relay determines a resource of a wireless channel for transmitting feedback to the source in response to the decoding attempt. If decoding is successful, the relay transmits the data to the destination. The destination then attempts to decode the data received from the relay. The destination may combine LLRs for the data and for a retransmission of the data. The destination determines a resource of a wireless channel for transmitting feedback to the relay in response to the decoding attempt. The resources are based on a relay identifier associated with the relay.

Abstract: A user equipment (UE) may partition a plurality of channels including physical uplink control channels (PUCCHs) and physical uplink shared channels (PUSCHs) into two groups, the plurality of channels being scheduled for transmission on a first set of component carriers (CCs) for communicating data and a second set of CCs for communicating control information and data, determine a first subset of PUSCHs of the one or more PUSCHs that is in the second set of CCs, determine that a first PUCCH of the one or more PUCCHs overlaps in time with at least a part of at least one PUSCH of the first subset of PUSCHs, and multiplex the first PUCCH with a first PUSCH of the first subset of PUSCH based on the determination that the first PUCCH overlaps in time with at least a part of the at least one PUSCH.

Abstract: To facilitate more efficient sidelink communications, methods, apparatuses, and computer program products are provided. An example method of a user equipment (UE) may include determining a configuration of a set of congestion control measurement resources comprising one or more receiving resources and one or more transmitting resources for transmission of an activity indication signal for sidelink communication. The example method further includes measuring received signal strength indicator (RSSI) on at least one of the one or more receiving resources.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a first user equipment (UE) may communicate with one or more second UEs to identify a resource overlap for a resource for relay communication. The first UE may selectively transmit using the resource with the resource overlap in accordance with a random access procedure. Numerous other aspects are described.

Abstract: Example implementations include a method, apparatus and computer-readable medium of wireless communication over a sidelink between a first user equipment (UE) and a second UE. The first UE may identify a configuration for discontinuous reception (DRX) for direct link communications with a second UE. The first UE may determine a channel busy ratio (CBR) based on a plurality of CBR measurement occasions within a time window prior to a direct link transmission based on the configuration for DRX. The first UE may determine whether to perform a congestion control on the direct link transmission based on the CBR. The first UE may perform a direct link transmission subject to a channel occupancy ratio limit.

Abstract: Aspects presented herein may improve sidelink discovery procedures for resource efficiency and/or power savings, where power consumption at a receiving sidelink device and/or at a transmitting sidelink device may be reduced when the devices are performing sidelink discovery procedures. In one aspect, an apparatus transmits, to a second wireless device, an indication that indicates in physical layer signaling whether a PSSCH carries a discovery message. The apparatus transmits the PSSCH (e.g., including a discovery message or a communication message) based at least in part on the indication.
