摘要： Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a transmitter user equipment (UE) may identify a sidelink resource allocation mode that indicates a manner in which one or more sidelink resources are allocated for use by the transmitter UE. The UE may transmit, to a receiver UE, sidelink control information (SCI) that includes an indication that is based at least on part on the sidelink resource allocation mode. Numerous other aspects are described.

摘要： This disclosure provides systems, methods, and devices for wireless communication that support configured reception with sidelink control information (SCI) repetition over a sidelink. In aspects, a receiving user equipment (UE) may be configured to conduct combined reception/decoding of SCI repetitions (received from a transmitting UE over a sidelink) over multiple time-frequency slots at pre-defined occasions (e.g., occasions configured by a base station) to decode a sidelink transmission. In aspects, a receiving UE may receive from a transmitting UE over a sidelink, a sidelink transmission during a reception occasion that includes a plurality of reception opportunities for the receiving UE. Each reception opportunity of the plurality of reception opportunities includes a repetition of an SCI. The receiving UE decodes the SCI by combining the repetitions of the SCI received in one or more reception opportunities, and decodes a data transmission (e.g., a physical sidelink shared channel (PSSCH) transmission) using the decoded SCI.

摘要： Methods, systems, and devices for wireless communications are described. Generally, the described techniques provide for a user equipment (UE) to transmit feedback information via a configurable quantity of interlaced resource blocks (IRBs) in one or more interlaces of a sidelink feedback channel. For example, the UE may transmit feedback via multiple IRBs of an interlace. The UE may determine which IRBs to use in accordance with a configuration, which may indicate a quantity of IRBs, a distribution of the IRBs, a pattern of the IRBs, or any combination thereof. Additionally, or alternatively, the UE may determine to transmit feedback via multiple IRBs of an interlace that is different from a common interlace.

摘要： Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a configuration that indicates multiple time intervals corresponding to multiple physical sidelink shared channels (PSSCHs) within a slot, wherein at least one PSSCH, of the multiple PSSCHs, starts in a symbol other than an initial data symbol of the slot. The UE may communicate in one or more PSSCHs, of the multiple PSSCHs, within the slot based at least in part on the configuration. Numerous other aspects are described.

摘要： Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may encode, for a first set of resource elements (REs), a first layer for sidelink control information. The UE may encode, for a second set of REs, a second layer for sidelink data, wherein the first set of REs and the second set of REs are associated with a same one or more symbols. The UE may transmit, to another UE and based at least in part on applying superposition coded modulation (SCM) to the first layer and the second layer, the sidelink control information using the first set of REs and the sidelink data using the second set of REs. Numerous other aspects are described.

摘要： Methods, systems, and devices for wireless communications are described. In some wireless communications systems, a user equipment (UE) may utilize opportunistic cooperative relaying to support exchanging packets between UEs without establishing or maintaining beamforming alignment between the UEs. Specifically, a source UE may invite nearby UEs (e.g., helper UEs) that receive a sidelink transmission (e.g., a packet meant for a different destination UE) to perform a single frequency network (SFN)-type transmission to opportunistically relay the packet to the destination UE. The helper UEs may receive, decode, and transmit the sidelink signaling from the source UE without establishing or configuring a relay agreement with the source UE. The destination UE may receive the sidelink signaling via cascading, SFN-type transmissions by one or more helper UEs. The destination UE may respond to the sidelink signaling with feedback information via one or more helper UEs or directly to the source UE.

摘要： Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a first UE may receive, from a second UE, resource reserving sidelink control information that indicates a transmit beam of the second UE and a sidelink resource of the second UE.
