Abstract: Channel access enhancement for new radio-unlicensed (NR-U) operations are disclosed. In attempting access to a shared communication channel, both base stations and user equipments (UEs) may operate similarly to load-based equipment (LBE) devices by performing extended clear channel access (eCCA) operations independently, such that each of the base stations and UEs may independently acquire the channel occupancy time (COT) of the shared communication spectrum.

Abstract: Methods, systems, and devices for wireless communications are described. A wireless device such as a user equipment (UE) may monitor a search space of a control channel for at least one downlink transmission. The UE may perform a plurality of decoding operations on a plurality of decoding candidates associated with the downlink control information format transmitted in a plurality of transmission time intervals (TTIs). In some cases, the plurality of decoding operations may comprise performing a first decoding on a first decoding candidate received in a current TTI, the first decoding operation applying a first descrambling code to the first decoding candidate, and performing a second decoding operation on a combined decoding candidate that comprises soft combined information from the first and second decoding candidate, the second decoding candidate received in a prior TTI.

Abstract: Techniques for alternative semi-persistent scheduling (SPS) parameter implementation in association with preemption of use of resources corresponding to other SPS parameters are described. Wireless devices may be implicitly informed with respect to implementing alternative resources corresponding to one or more alternative SPS parameters when use of resources corresponding to first SPS parameters is preempted. A disruption indication (DI), such as used to indicate preemption of downlink transmission on downlink SPS allocated resources and/or a cancellation indication of uplink transmission on uplink SPS allocated resources, may be used to inform (e.g., implicitly) one or more wireless devices to employ alternative resources corresponding to alternative SPS parameters available to the wireless devices. Other aspects and features are also claimed and described.

Abstract: Methods, systems, and devices for wireless communications are described. A first user equipment (UE) may determine that the first UE is to receive a sidelink transmission from a second UE, the sidelink transmission comprising a sidelink control channel and a sidelink data channel. The first UE may receive, based at least in part on a first resource configuration for a sidelink feedback channel failing to satisfy a resource threshold associated with transmitting a feedback message, an indication of a second resource configuration from the second UE, the second resource configuration for transmitting the feedback message to the second UE for the sidelink transmission, the second resource configuration satisfying the resource threshold. The first UE may receive the sidelink transmission from the second UE. The first UE may transmit, to the second UE, the feedback message using the second resource configuration.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine a power headroom (PHR) value for a component carrier (CC) based at least in part on a physical uplink shared channel (PUSCH) transmission in the CC, wherein the PUSCH transmission includes a first repetition associated with a first set of power control parameters and a second repetition associated with a second set of power control parameters, and wherein the PHR value is determined based at least in part on one or more of the first repetition or the second repetition. The UE may transmit information identifying the PHR value for the CC. Numerous other aspects are provided.

Abstract: Wireless communications systems and methods related to on-demand cell coverage extension for broadcast signals are provided. A first wireless communication device communicates, with a second wireless communication device, a first extended cell coverage request. The first wireless communication device communicates, with the second wireless communication device, a first broadcast communication signal in an extended cell coverage mode in response to the first extended cell coverage request. The first broadcast communication signal includes a system information block repeated in at least one of a time domain or a frequency domain.

Abstract: Systems and methods implementing receiver assisted channel access procedures configured to enable access for a potential transmitter while avoiding introducing unacceptable interference with respect to ongoing communications in a shared channel are described. In examples, a receiver assisted channel access procedure implements a LBT enhanced CCA (eCCA) technique in which receiver assisted transmitter sensing is utilized. A receiver assisted channel access procedure may implement monitoring of a shared channel during a contiguous contention period for one or more instances of a periodic session protection signal.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may obtain a channel occupancy time (COT) in an unlicensed frequency spectrum band. The COT may include an initial time interval for an initial transmission and a subsequent time interval for a subsequent transmission. In the initial time interval, the UE may transmit control information and data to another UE, where the control information indicates the subsequent time interval. The other UE may selectively perform communications during the subsequent time interval. The UE may perform the subsequent transmission during the subsequent time interval.
