Abstract: Methods, systems, and devices for wireless communication are described. Some wireless communications systems may support a slot transmission detection procedure for sidelink communications. A sidelink user equipment may monitor, during a slot and within one or more subbands, for signaling associated with a first sidelink transmission that corresponds to resources that span a duration of the slot. The signaling may include sidelink control information, a demodulation reference signal, or other sidelink signaling associated with the first sidelink transmission. The user equipment may determine a signal strength or one or more other parameters associated with the signaling. The user equipment may determine whether to transmit a second sidelink transmission having a duration that is less than a first duration of the first sidelink transmission based on the signal strength, the one or more parameters, or both associated with the signaling.

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 performing a clear channel assessment (CCA), transmitting, to a first UE based on the CCA being successful, a first transport block (TB) via a first sub-PSSCH associated with a first sub-slot, and transmitting, to at least one of the first UE or a second UE, a second TB via a PSSCH associated with a slot.

Abstract: This disclosure provides systems, methods, and apparatus, including computer programs encoded on computer storage media, for performing a common channel sensing procedure for transmissions via a mobile termination (MT) role or via a distributed unit (DU) role of an integrated access and backhaul (IAB) node, or both. In one aspect, the IAB node may obtain channel access for transmissions via the MT role or the DU role, or both, using the same channel sensing procedure. The IAB node may select a timing of a sensing slot for the common channel sensing procedure in accordance with a capability of the IAB node and a timing of the transmissions. The IAB node may initiate a channel occupancy time (COT) for the transmissions via the MT role or the DU role, or both, as a result of determining that a measured energy detection (ED) value satisfies an ED threshold.

Abstract: Methods, systems, and devices for wireless communications are described. In some wireless communications systems, a base station may transmit a control channel such as a PDCCH using one or more control resource sets (CORESETs). A CORESET may be associated with a number of different transmission configuration indicator (TCI) states which may specify information that a UE may use to receive the PDCCH. In some cases, the UE may identify an association between resources of the CORESET and a number of TCI states assigned to a CORESET using various different multiplexing techniques, such as time division multiplexing (TDM). Some associations between the resources of the CORESET and the TCI states may include a mapping of the resources of the CORESET to the different TCI states. The UE may decode the PDCCH based on the different TDM techniques used to configure the CORESET.

Abstract: Bi-static radio-based object location detection can include determining, by a wireless device, a location of a remote wireless device; obtaining a ToF and an angle of arrival (AoA) of a reflected WWAN reference signal reflected by a remote object; and determining a location of the remote object based on the location of the remote wireless device, the ToF, and the AoA. In another example, a wireless device includes a wireless transceiver; a non-transitory computer-readable medium; and a processor communicatively coupled to the wireless transceiver and non-transitory computer-readable medium, the processor configured to determine a location of a remote wireless device; obtain a ToF and an angle of arrival (AoA) of a reflected WWAN reference signal reflected by a remote object; and determine a location of the remote object based on the location of the remote wireless device, the ToF, and the AoA.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may determine, based at least in part on a first downlink reference signal transmitted from a first base station using a downlink reference signal frequency, a first frequency offset associated with transmissions between the UE and the first base station. The UE may determine, based at least in part on a second downlink reference signal transmitted from a second base station using the downlink reference signal frequency, a second frequency offset associated with transmissions between the UE and the second base station. The UE may transmit, to the first base station and the second base station, at least one uplink reference signal using an uplink reference signal frequency that is based at least in part on the first frequency offset and the second frequency offset.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive an indication of a set of aggregation levels for a set of physical downlink control channel (PDCCH) candidates within a search space. The UE may decode a first subset of PDCCH candidates, of the set of PDCCH candidates, that are each aggregated within a single PDCCH monitoring occasion, and a second subset of PDCCH candidates, of the set of PDCCH candidates, that are each aggregated across multiple PDCCH monitoring occasions. Numerous other aspects are described.

Abstract: A user equipment (UE) detects a beam switching event and switches, in response to the beam switching event, a beam for communications on a first active component carrier. The UE applies a beam switch interruption time across one or more second active component carriers if a beam switching delay associated with the beam switch exceeds a threshold value.

Abstract: Methods, systems, and devices for wireless communications are described. For example, a first communication device may receive, from a second communication device, control signaling triggering a channel access procedure at the first communication device. In some case, the channel access procedure may be for accessing the shared radio frequency spectrum. The first communication device may then perform the channel access procedure based on the control signaling. In some examples, the first communication device may, based on the channel access procedure, transmit an indication of a channel occupancy initiated by the first communication device to the second communication device. The first communication device may relay communications between the second communication device and a third communication device during a channel occupancy time (COT) based on the transmitted indication of the channel occupancy initiated by the first communication device.

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, an indication that one or more semi-persistent scheduling (SPS) occasions, within a periodic set of SPS occasions, will be skipped. Accordingly, the UE may refrain from monitoring, for signals from the base station, during the one or more SPS occasions that are skipped. Additionally, in some aspects, the UE may refrain from transmitting, to the base station, acknowledgment feedback associated with the one or more SPS occasions that are skipped. Numerous other aspects are provided.
