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 base station receives feedback for a first data transmission or an indication to retransmit a first data transmission, the first data transmission being transmitted to at least one wireless device from another wireless device. The base station transmits, in response to the feedback or the indication, a retransmission of the first data transmission in a downlink transmission to the at least one wireless device.

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.

Abstract: Methods, systems, and devices for wireless communications are described. A first user equipment (UE) may determine a first set of resources for communications over a sidelink communication link between the first UE and a second UE. The first UE may transmit, to the second UE via the sidelink communication link, a first sidelink control information including a reverse sidelink scheduling indicator based on determining the first set of resources. The first UE may additionally transmit, to the second UE via the sidelink communication link, a second sidelink control information indicating a second set of resources for reverse sidelink transmissions from the second UE to the first UE over the sidelink communication link, where transmitting the second sidelink control information is based on transmitting the first sidelink control information. The first UE may receive, from the second UE, a reverse sidelink message in response to transmitting the second sidelink control information.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a first device may receive, from a second device, a sounding reference signal (SRS) prior to a scheduled communication. The first device may transmit, to the second device, an indication that a measurement of the SRS does not satisfy a threshold, if the measurement of the SRS does not satisfy the threshold. The first device may activate, based at least in part on the transmitting the indication and before the scheduled communication, a multi-point communication mode. Numerous other aspects are described.

Abstract: Methods, systems, and devices for wireless communication are described. Generally, the described techniques provide for forward/retransmitting a data transmission to a target UE through a helper UE. A helper UE may receive a data transmission from a network node, determining whether the received data transmission is intended for a target UE or for the helper UE itself, based on a control message, and retransmitting the data transmission to the target UE upon determining that the data transmission is intended for the target UE. A network node such as a base station may transmit a control message to at least a help UE, the control message comprising an indicator of whether a data transmission is intended for the helper UE or a target UE and transmit the data transmission to at least the helper UE and the target UE.

Abstract: Methods, systems, and devices for wireless communications are described. The method includes receiving, from a second UE, a configuration for receipt of a sidelink resource pool message, determining that the first UE has information to be transmitted to the second UE via sidelink communications, receiving, in accordance with the configuration, the sidelink resource pool message, identifying, based on the sidelink resource pool message, a resource pool that includes sub-channels for sidelink communications to the second UE, and attempting to access a sub-channel of the resource pool in order to transmit the information to the second UE via sidelink communications.

Abstract: Methods, systems, and devices for wireless communications are described. In some systems, a user equipment (UE) may perform single frequency network (SFN) manner relaying in sidelink to support exchanging packets between UEs, for example, without maintaining beamforming alignment between the UEs. A first UE (e.g., a source UE or destination UE) may establish a pre-agreement with a second UE for the second UE to operate as an SFN-manner relay over sidelink for the first UE. The pre-agreement may be reached via a publish-and-subscription procedure, in which the second UE publishes an SFN-type relaying service and the first UE subscribes to the SFN-type relaying service. The second UE may receive sidelink signaling associated with the first UE (e.g., transmitted by or to the first UE) and may relay the sidelink signaling in a resource configured for SFN-type transmission based on the first UE being subscribed to the SFN-type relaying service.
