Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from a base station, configuration information including multiple transmission configuration indication (TCI) states associated with a control resource set (CORESET). The UE may receive, from the base station, a physical downlink control channel (PDCCH) in a region associated with the CORESET, wherein the PDCCH includes at least one control channel element (CCE). The UE may perform blind decoding for multiple configured PDCCH candidates based at least in part on a resource element group (REG) bundle included in the at least one CCE, wherein the multiple configured PDCCH candidates are associated with one or more of the multiple TC states associated with the CORESET. Accordingly, the UE may identify the PDCCH transmitted by the base station based at least in part on the blind decoding.

Abstract: Enhancement for bandwidth part (BWP) is disclosed. A base station configures a plurality of BWPs, and activate multiple BWPs for downlink and multiple BWPs for uplink from the plurality of the configured BWPs at a given time. Downlink control information (DCI) that includes BWP activation information can be transmitted on a physical downlink control channel (PDCCH) to a user equipment (UE). The BWP activation information includes a link direction, a schedule of the one or more multiple BWPs for downlink and multiple BWPs for uplink, numerologies, reserved sub-band information, tracking reference signal configuration, or any combination thereof. Correspondingly, a UE receives DCI on a PDCCH that includes BWP activation information, and determines activation of multiple BWPs for downlink and multiple BWPs for uplink at a given time based on the received DCI and its capabilities. Associated enhancement for PDCCH and PDSCH scheduling and LBT procedures are also disclosed.

Abstract: Wireless communications systems and methods related to sidelink communications in a shared radio frequency band are provided. A first user equipment (UE) receives, from a base station (BS), a configuration for frequency-interlaced resources in a shared radio frequency band for sidelink communication between the first UE and a second UE. The first UE communicates, with the second UE, the sidelink communication using the frequency-interlaced resources.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a transmitter node may determine a set of desired transmit beams to use for transmissions during a channel occupancy time (COT), wherein each transmit beam in the set of desired transmit beams is associated with an energy detection threshold (EDT). The transmitter node may configure a sensing beam associated with a directional listen-before-talk (LBT) procedure, wherein the sensing beam is associated with an EDT that is at least as strict as a strictest EDT associated with the set of desired transmit beams. The transmitter node may transmit using the set of desired transmit beams during the COT, wherein the COT is initiated based at least in part on an indication that the directional LBT procedure succeeded using the sensing beam. Numerous other aspects are described.

Abstract: Aspects of the present disclosure relate to wireless communications, and more particularly, to techniques for determining quasi co-location (QCL) and/or transmission configuration information (TCI) state assumption information for a dynamic control resource set (CORESET). In some cases, if certain conditions are met, a user equipment (UE) may follow QCL assumptions for a physical downlink shared channel (PDSCH) scheduled by a same PDCCH that indicated the dynamic CORESET. An example method by a UE generally includes receiving at least one downlink control information (DCI), of a first physical downlink control channel (PDCCH), that schedules at least one dynamic CORESET; and receiving a second PDCCH in the dynamic CORESET, wherein the UE is to apply at least one QCL assumption associated with a PDSCH for the at least one dynamic CORESET if one or more conditions are met.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may monitor a unicast channel for a first downlink transmission from a base station using a first semi-persistent scheduling (SPS) configuration. The UE may receive downlink control information (DCI) from the base station indicating a second SPS configuration associated with a different coverage level than the first SPS configuration. In some cases, the DCI may be DCI that is common to a set of UEs. Here, the DCI may indicate the second SPS configuration and the UE may identify a set of parameters associated with the second SPS configuration based on a radio resource control (RRC) message received prior to the DCI. Based on receiving the indication of the second SPS configuration, the UE may monitor the unicast channel for a second downlink transmission from the base station using the second SPS configuration.
