Abstract: Methods, systems, and devices for wireless communications are described. For example, a method for wireless communications at a transmitting user equipment (UE) may include receiving, from a base station, a resource configuration of sidelink communications. The transmitting UE may transmit, to a receiving UE, sidelink control information (SCI) via one or more SCI messages, the SCI comprising one or more semi-persistent scheduling indications pertaining to a semi-persistent scheduling configuration for communications from the transmitting UE to the receiving UE. The transmitting UE may monitor for feedback information pertaining to the SCI prior to proceeding with semi-persistent scheduled sidelink transmissions in accordance with the one or more semi-persistent scheduling indications.

Abstract: Disclosed are various techniques for wireless communication. In an aspect, a method of wireless communication includes determining, based on environment information about an environment in which a user equipment (UE) that is receiving positioning reference signals (PRSs) using a first bandwidth (BW) is operating, a second BW to be used by the UE for receiving PRSs, and transmitting PRSs using the second BW to be used by the UE for receiving PRSs.

Abstract: Methods, systems, and devices for wireless communications are described. A first device, which may be a user equipment (UE), may transmit a sidelink control information SCI) message (e.g., an SCI-1 message) on a physical sidelink control channel (PSCCH) to a group of devices. The SCI may message may reserve a set of sidelink resources for a sidelink communication between the first device and a second device of the group of devices. The first device may receive an acknowledgment (ACK) message on a physical sidelink feedback channel (PSFCH) from the second device. Based on receiving the ACK message, the first device may release the set of sidelink resources and may transmit a release message (e.g., a physical sidelink release channel (PSRCH) message) on a PSRCH that includes an indication of the released set of sidelink 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: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a base station (BS) may transmit, and a user equipment (UE) may receive, a group-common downlink control information (DCI) message, wherein the group-common DCI message includes information identifying at least one communication parameter for a plurality of UEs. The BS and the UE may communicate in accordance with the at least one communication parameter based at least in part on the BS transmitting the group-common DCI message to the plurality of UEs and the UE receiving the group-common DCI message. Numerous other aspects are provided.

Abstract: Methods, systems, and devices for wireless communications are described. A base station may send coupled configured grants to a transmitter user equipment (UE) and a receiver UE, respectively. For example, when transmitting a pair of configured grants that includes a first configured grant sent to a first UE and a second configured grant sent to a second UE, the base station may include an indication in each of the configured grants that sidelink semi-persistent scheduling resources are activated or deactivated. Additionally, the configured grants may indicate which UE is a receiver and which UE is a transmitter. For instance, the first configured grant may indicate that a first UE is to be the transmitter and a second configured grant indicate that a second UE is to be the receiver.

Abstract: In an aspect of the disclosure, a method, a computer-readable medium, and an apparatus are provided. The apparatus may be a user equipment (UE). The apparatus may transmit a supported configuration of the UE for at least one of SRS transmission or CSI-RS reception for communication with a plurality of TRPs. The apparatus may receive, in response to transmitting the supported configuration, configuration information for at least one of the SRS transmission or the CSI-RS reception, wherein the configuration information is generated based on the supported configuration. The apparatus may communicate, with at least a subset of the plurality of TRPs, using at least one of the SRS transmission or the CSI-RS reception on resource elements assigned based on the configuration information. A base station connected to the TRPs may use the SRS/CSI-RS for cluster management and scheduling or to estimate downlink channels to determine precoding for downlink transmissions.

Abstract: Systems and non-transitory computer-readable mediums for scheduling resources for a specific sidelink are described. Some embodiments provide scheduling of resources for a sidelink between a first user equipment (UE) in communication with a base station and a specified second UE in communication with the first UE, such as using downlink control information (DCI) and/or radio resource control (RRC) signaling. The scheduling of sidelink resources may be with respect to a dynamic grant (DG) or a configured grant (CG). Other aspects and features are also claimed and described.
