Abstract: Apparatus, methods, and computer-readable media for facilitating opportunistic CSI for sidelink communication are disclosed herein. An example method for wireless communication at a responding sidelink UE includes receiving, from an initiating sidelink UE, a request to provide CSI feedback to the initiating sidelink UE, the request excluding a CSI-RS. The example method also includes decoding a transmission from the initiating sidelink UE to a neighboring sidelink UE, the transmission including a CSI feedback trigger. The example method also includes transmitting, to the initiating sidelink UE, a CSI report based on the transmission.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine an amount of time between uplink allocations that is needed for performing frequency retuning during operation at a subcarrier spacing (SCS). The UE may perform frequency retuning in association with hopping from a first set of frequency resources, associated with transmitting a first uplink transmission, to a second set of frequency resources, associated with transmitting a second uplink transmission, during operation at the SCS, wherein the frequency retuning is performed during a set of consecutive unallocated resources determined based at least in part on the amount of time between uplink allocations that is needed for performing frequency retuning. Numerous other aspects are described.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive sounding reference signal (SRS) resource set configuration information that indicates an aperiodic SRS resource set, an aperiodic downlink reference signal resource associated with the aperiodic SRS resource set, and a slot offset associated with the aperiodic downlink reference signal resource. The UE may receive downlink control information indicating that the aperiodic SRS resource set is triggered and determine a quasi co-location assumption for the aperiodic downlink reference signal resource based on the slot offset associated with the aperiodic downlink reference signal resource. The UE may measure the aperiodic downlink reference signal resource in a slot indicated by the slot offset based on the quasi co-location assumption.

Abstract: Wireless communications systems and methods related monitoring the start of a transmission opportunity (TXOP) in unlicensed or shared frequency bands are provided. In one embodiment, a first wireless communication device communicates, with a second wireless communication device, a first configuration including a set of first control channel monitoring periods outside of a TXOP. The first wireless communication device communicates, with the second wireless communication device, a communication signal during the TXOP based on a second control channel monitoring period longer than each of the first control channel monitoring periods. In one embodiment, a first wireless communication device communicates, with a second wireless communication device, a configuration including a first search space for a control channel monitoring outside of a TXOP and a second search space for a control channel monitoring within the TXOP, the second search space being partially-overlapped with the first search space.

Abstract: The present disclosure describes various aspects of the implementation and design of Physical Downlink Control Channel (PDCCH) in 5G new radio (NR) applications. Aspects include methods, apparatuses, and computer-readable medium for one or more of multiple PDCCH search spaces, control resource block (CRB), irregular multiple slots or mini-slots grants, or fast control channel signaling for grant-free uplink (UL). For example, different scheduling entities can each have one or two search spaces defined (e.g., common and/or user equipment (UE)-centric search spaces). Also, CRBs can be used as units for PDCCH transmission instead of resource element groups/control channel elements (REGs/CCEs). In addition, irregularities in time domain, frequency domain, or both can be introduced in the granting of resource blocks (RBs) over multiple slots or mini-slots. Moreover, signaling can be used to indicate to a UE configured for grant-free UL the portion of the pool of resources available for grant-free UL.

IPC: H04W72/12
Abstract: Aspects relate to techniques for facilitating sidelink cancellation. A network entity, such as a base station, may schedule a sidelink transmission between a transmitting wireless communication device and a receiving wireless communication device and transmit scheduling information for the sidelink transmission to at least the transmitting wireless communication device. The network entity may further transmit control information including a cancellation indication to at least the transmitting UE. The cancellation indication may indicate at least an overlap between a portion of the resources allocated to the sidelink transmission and an additional transmission. Based on the cancellation indication, the transmitting wireless communication device may modify the sidelink transmission.

Abstract: Aspects relate techniques for facilitating resumption of a sidelink transmission after cancellation of the sidelink transmission within resources that overlap with an additional transmission. A transmitting wireless communication device may receive control information from a network entity including a cancellation indication indicating overlapping resources between the resources scheduled for the sidelink transmission and resources scheduled for the additional transmission. Based on the cancellation indication, the transmitting wireless communication device may cancel the sidelink transmission within cancelled resources including at least the overlapping resources and transmit the sidelink transmission via remaining resources of the scheduled resources for the sidelink transmission outside of the cancelled 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 mapping a transport block (TB) to a first sub-physical sidelink shared channel (sub-PSSCH) of a plurality of sub-PSSCHs of a PSSCH and transmitting, to at least one other UE, the TB via the first sub-PSSCH.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a receiving user equipment (UE) may receive, from a transmitting UE, a sidelink reference signal in a first symbol of a slot. The receiving UE may perform a joint channel estimation and an automatic gain control (AGC) based at least in part on the sidelink reference signal received in the first symbol of the slot. Numerous other aspects are described.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may indicate support of an extended cyclic prefix (ECP), where a duration of the ECP or transmitting the ECP is based on the indication. In some cases, the UE may receive an uplink grant to transmit an uplink message with an indication of the ECP, and the UE may transmit the ECP and uplink message according to a timeline based in part on the ECP. Additionally or alternatively, an uplink channel allocation indicated in the uplink grant may include a starting point for the ECP, where the UE transmits the ECP at the starting point. In some cases, the UE may multiplex uplink control information (UCI) in the uplink channel based on a timeline that is based in part on the ECP.
