Abstract: Aspects of the present disclosure provide techniques for configuring a search space for sidelink communications between a plurality of user equipments (UEs). Particularly, the techniques described herein configure a search space (e.g., subset of all available sub-channels) to decode the sidelink packets (e.g., physical sidelink control channel (PSCCH) and physical sidelink shared channel (PSSCH)) transmitted between a first UE and a second UE over sidelink communication without the need for the receiver UE (e.g., second UE) to perform blind decoding of all sidelink sub-channels as is currently required in conventional systems. Thus, the disclosed techniques reduce latency and maximize the resource utilization (e.g., by using less processing power and bandwidth) for sidelink communications

Abstract: Certain aspects of the present disclosure provide techniques for sending a retransmission via a sidelink wireless communication channel. A method that may be performed by a first user equipment (UE) includes receiving, from a base station, a first data transmission. The method also includes receiving, from the base station, a signal indicating to retransmit at least a portion of the first data transmission to a second UE. The method further includes transmitting, to the second UE, based at least in part on the signal, a second data transmission via one or more resources, the second data transmission comprising at least the portion of the first data transmission.

Abstract: Methods, systems, and devices for wireless communication are described. A wireless device may receive an indicator of resource allocation for a plurality of UEs, determine, based at least on a grouping of the plurality of UEs, resources from the resource allocation for receiving data at the UE, and receive the data on the determined resources. A base station may receive a plurality of acknowledgement reports from a plurality of UEs, determine, based on a grouping of the plurality of UEs, a resource allocation for each UE from which a negative acknowledgement was received, and transmit an indicator of the resource allocation.

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 user equipment (UE) may receive a downlink data communication. The UE may determine a processing time for the downlink data communication based at least in part on at least one of: whether the downlink data communication was scheduled via preconfigured scheduling or via a downlink grant received in a downlink control channel, or whether the downlink data communication is an initial transmission or a retransmission. The UE may transmit acknowledgement or negative acknowledgement (ACK/NACK) feedback, corresponding to the downlink data communication, using a timing indicated by the processing time. Numerous other aspects are provided.

Abstract: Methods and apparatuses are disclosed for intra-cell interference management of device-to-device (D2D) communication. A plurality of user equipments (UEs) in a cell transmit a reference signal in turn in a first rotation. A scheduling entity groups the D2D connections into a plurality of clusters based on measurement reports of the reference signal such that an interference between D2D connections of different clusters is below a predetermined threshold. The scheduling entity requests the UEs of each cluster to transmit the reference signal in turn according to a second rotation such that two or more UEs corresponding to different clusters transmit the reference signal using a same network resource.

Abstract: Wireless communications systems and methods related to managing interference among feedback transmissions are provided. A first wireless communication device receives, from a second wireless communication device, a first forward data transmission request signal over a first link in a first link direction, wherein the first forward data transmission request signal is associated with a first feedback transmission over the first link in a second link direction opposite the first link direction. The first wireless communication device yields, in response to the first forward data transmission request signal, access to a channel resource for the first feedback transmission based on at least an interference tolerance level of the second wireless communication device and an interference level on the first feedback transmission from the first wireless communication device
