Abstract: Apparatus, methods, and computer-readable media for facilitating support for an increased quantity of sidelink configured grants are disclosed herein. An example method for wireless communication at a user equipment (UE) includes receiving scheduling information corresponding to a first quantity of sidelink configured grants, the first quantity of sidelink configured grants being greater than eight sidelink configured grants. The example method also includes receiving, from a base station, an activation of a sidelink configured grant of the first quantity of sidelink configured grants. The example method also includes transmitting sidelink traffic to a second UE based on the sidelink configured grant.

Abstract: Network-controlled power control for side-link communications is disclosed. According to the described aspects, a power control framework is defined for network-controlled side-band or device-to-device (D2D) communications, in which transmission power for side-link communications may be stepped up enough for a base station in a connected mode with at least one of multiple user equipment (UE) devices to detect side-link communications between the UEs in order to take responsive action to enhance the reliability of the communications. The base station provides the configuration information to the UEs which may be used when preparing for transmissions of side-link traffic and/or feedback.

Abstract: Certain aspects of the present disclosure provide a method for wireless communications by a transmitter UE. The method generally includes receiving, from a network entity, a downlink control information (DCI) allocating resources in an unlicensed frequency band for multiple physical sidelink shared channel (PSSCH) transmissions to at least one receiver UE across transmission time intervals (TTIs), performing a listen-before-talk (LBT) channel access procedure in the TTIs, and transmitting at least one LBT report to the network entity on a physical uplink control channel (PUCCH) resource that occurs before another PUCCH resource used for transmitting acknowledgment feedback for the PSSCH transmissions.

Abstract: Methods, systems, and devices for wireless communications are described that support sidelink cancellation for out of coverage user equipment. Described techniques provide for signaling of cancellation indications to a user equipment (UE) or a group of UEs to refrain from performing sidelink communications on a set of resources. A base station may transmit a cancellation indication to one or more sidelink UEs via an access link that indicates that an allocation of one or more resources for sidelink communications has been canceled. A first UE may receive the cancellation indication from the base station via the access link and transmit a sidelink communication to one or more other UEs that indicates the canceled resource allocation. Based on the sidelink communication of the cancellation indication from the first UE, the one or more other UEs may refrain from transmitting using the canceled resources.

Abstract: Wireless communications systems and methods related to communicating control information are provided. A method of wireless communication performed by a user equipment (UE) may include performing a clear channel assessment (CCA), transmitting, to a first UE based on the CCA being successful, a first transport block (TB) via a first sub-PSSCH associated with a first sub-slot, and transmitting, to at least one of the first UE or a second UE, a second TB via a PSSCH associated with a slot.

Abstract: Certain aspects of the present disclosure provide techniques for autonomous reference signal transmission configuration. Certain aspects provide a method of receiving a configuration message from the base station, wherein the configuration message comprises an indication of a set of candidate resources for transmitting the reference signal. Certain aspects provide a method of detecting a future downlink transmission from the base station, and other aspects provide a method of transmitting, in response to detecting the future downlink transmission, the reference signal utilizing a first resource of the set of candidate resources prior to receiving the future downlink transmission via a second resource in the set of candidate resources.

Abstract: Certain aspects of the present disclosure provide techniques for support response-based resource management. A UE may determine an uplink response to be transmitted in response to a downlink transmission by a first TRP participating in CoMP to the UE with a second TRP. The first UE may select which of the first TRP or the second TRP to transmit the uplink response to, based at least in part on the determined uplink response and may transmit the uplink response to the selected first or second TRP.

Abstract: Example implementations include a method, apparatus and computer-readable medium of wireless communication over a sidelink between a transmitting user equipment (UE) and a receiving UE. The receiving UE may receive a configuration of multiple resource pools for sidelink communications. The transmitting UE may transmit at least two repetitions of a sidelink control information (SCI) on at least two of the multiple resource pools. Each repetition of the SCI includes a reservation for a physical sidelink shared channel (PSSCH) on a respective resource pool. The receiving UE may perform soft combining on the at least two repetitions of the SCI to determine resources for the PSSCH. The receiving UE may decoding the PSSCH based on the SCI, for example, by combining multiple repetitions of the PSSCH on the reservations indicated by the SCI.

Abstract: A first user equipment (UE) is configured to communicate with a second UE in sidelink communications using a sidelink configured grant (CG) configured by a base station. The first UE receives, a radio resource control (RRC) message or physical layer signaling including a sidelink configured grant (CG) configuration indicating at least some parameters configured by a base station for sidelink communications between the first UE and a second UE. The first UE transmits or receives a transport block for the sidelink communications on a physical sidelink shared channel (PSSCH) based on the at least some parameters.
