Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, on a particular control resource set (CORESET), downlink control information (DCI) scheduling a physical downlink shared channel (PDSCH) or a physical uplink shared channel (PUSCH). The UE may be configured with multi-DCI based multi-transmission/reception point (TRP) operation. The UE may determine, based at least in part on the UE being configured with multi-DCI based multi-TRP operation, a fixed higher layer index that identifies a CORESET group with which the particular CORESET is associated. The UE may perform an operation, associated with receiving the PDSCH or transmitting the PUSCH, based at least in part on the fixed higher layer index identifying the CORESET group with which the particular CORESET is associated. Numerous other aspects are provided.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a first user equipment (UE) may transmit, to a second UE via a sidelink sub-channel of a primary carrier, an indication that identifies one or more resources on the primary carrier for transmitting one or more hybrid automatic repeat request (HARQ) responses for one or more sidelink communications between the first UE and the second UE on a secondary carrier; and receive, from the second UE, on the one or more resources on the primary carrier, the one or more HARQ responses for the one or more sidelink communications on the secondary carrier. Numerous other aspects are provided.

Abstract: Methods, systems, and devices for wireless communications are described. An example method for wireless communication at a first wireless device, such as a user equipment (UE) may include receiving, at the first wireless device, a first sidelink control information (SCI) message from a second wireless device, wherein the first SCI message indicates a scheduling conflict between a first data transmission of the second wireless device and a second data transmission of the first wireless device. The method may also include transmitting a second SCI message from the first wireless device based at least in part on the scheduling conflict between the first data transmission and the second data transmission, wherein the second SCI message indicates a data resource allocation for the second data transmission that mitigates the scheduling conflict.

Abstract: This disclosure provides systems, methods, and apparatuses for channel occupancy time (COT) sharing arrangements when two or more COTs are associated with different durations, and provides arrangements for base station scheduling of downlink transmissions and selection of a listen-before-talk (LBT) configuration when two or more COTs are associated with different user equipment (UE) transmission endpoints. Furthermore, this disclosure provides systems, methods, and apparatuses for UE-side communication in accordance with scheduling information determined based on such COT sharing arrangements. By providing COT sharing arrangements when two or more COTs are associated with different durations, unlicensed channel utilization may be improved and throughput may be increased relative to when only one UE's COT can be used by the base station. By providing arrangements for scheduling downlink transmissions and selecting an LBT configuration, unlicensed channel utilization may be improved and access to the unlicensed medium may be streamlined.

Abstract: Certain aspects of the present disclosure provide a method for wireless communications by a transmitter UE. The method generally includes receiving, from a network entity, a downlink control information (DCI) allocating resources in an unlicensed frequency band for multiple physical sidelink shared channel (PSSCH) transmissions across multiple transmission time intervals (TTIs), performing a listen-before-talk (LBT) channel access procedure in the TTIs, and transmitting, to at least one receiver UE, one or more PSSCHs in one or more of the TTIs being indicated as passing the LBT channel access procedure based on the performance.

Abstract: Methods, systems, and devices for wireless communications are described. In some systems, a base station may configure allocate resources for sidelink communication between a first user equipment (UE) and a second UE as part of a sidelink communication mode 1 and, in some implementations, may configure the first UE (a sidelink receiver) with a set of periodic reception occasions, each reception occasion including multiple reception opportunities for receiving sidelink control information (SCI) from the second UE (a sidelink transmitter). In some examples, each reception opportunity may be associated with a different receive beam and, as such, the first UE may monitor for the SCI from the second UE over different reception opportunities and using different receive beams. Such configured beam-sweeping reception for SCI may increase sidelink reliability as a result of greater spatial diversity, which may increase the likelihood for successful communication between the first UE and the second UE.

Abstract: Methods, systems, and devices for wireless communication are described. A user equipment (UE) may transmit one or more random access messages during a random access procedure between the UE and a base station. The UE may receive a control signal that includes a spatial relation configuration for transmission, by the UE, of an uplink signal. The spatial relation configuration may indicate that transmission of the uplink signal is via a transmit beam used in transmitting one of the random access messages. The spatial relation configuration may configure a spatial relation information element (IE) to identify the random access message. The UE may receive the spatial relation configuration identifying the random access message, and the UE may transmit the uplink signal using a same transmit beam used for transmission of the random access message.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive a plurality regulation requirement parameters corresponding to an unlicensed carrier, where the unlicensed carrier spans at least a portion of a first unlicensed band associated with a first set of regulation requirements and at least a portion of a second unlicensed band associated with a second set of regulation requirements. The UE may identify, from the plurality of regulation requirement parameters, a set of regulation requirement parameters for an uplink transmission based at least in part on whether a set of frequency resources for the uplink transmission overlaps with the first unlicensed band and the second unlicensed band. The UE may transmit the uplink transmission using the set of regulation requirement parameters.
