Abstract: 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.

Abstract: 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.

Abstract: Coordination of listen before talk (LBT) structure in new radio (NR) unlicensed (NR-U) multi-channel access operations is disclosed. In one aspect, when a base station determines to access shared communication spectrum, it may transmit an LBT structure signal that identifies the current LBT structure. The base station would then attempt access to the shared spectrum according to the LBT structure. In another aspect, a coordination server is used to manage access to the shared spectrum. Each node desiring access registers with the coordination server, which provides access parameters for the accessing node to use that increases the likelihood of successful access. The accessing nodes will transmit the selected access configuration used to access the shared spectrum, wherein the access configuration is selected based on the access parameters.

Abstract: Methods, systems, and devices for wireless communications are described in which a first user equipment (UE) may transmit sidelink communications to a second UE, and the second UE may provide feedback associated with the sidelink communication to the first UE in a sidelink control information (SCI) transmission. In some cases, the SCI is first stage SCI transmitted in a sidelink control channel or second stage SCI transmitted in a sidelink shared channel. The feedback may include one or more of acknowledgment/negative-acknowledgment feedback, channel state information feedback, a scheduling request, or any combinations thereof. In some cases, the first UE may indicate resources of the second slot to the second UE for transmission of the feedback in the SCI, such as by providing a time offset value and resource index that identifies the resources.

Abstract: Wireless communications systems and methods related to discontinuous reception (DRX) extended-on operations and dynamic transmission patterns in sidelink are provided. A first user equipment (UE) determines a transmission pattern for a first sidelink based on an extended DRX on-duration associated with a second sidelink different from the first sidelink, wherein the first sidelink is between the first UE and a second UE, and wherein the second sidelink is between the second UE and a third UE. The first UE transmits, to the second UE over the first sidelink during the extended DRX on-duration based on the transmission pattern, a communication signal.

Abstract: Wireless communications systems and methods related to channel access contention management in a shared radio frequency band are provided. A first wireless communication device performs, during a first time period, a first clear channel assessment (CCA) in a shared radio frequency band based on a first energy detection threshold, wherein performing the first CCA comprises obtaining at least one signal energy measurement. The first wireless communication device then performs, during a second time period subsequent to the first time period, a second CCA in the shared radio frequency band based on a second energy detection threshold, the second energy detection threshold being based on the at least one signal energy measurement. The wireless communication device then transmits, to a second wireless communication device in the shared radio frequency band based on the second CCA, a communication signal.
