Abstract: Methods, systems, and devices for wireless communications are described. The method includes receiving a configuration message indicating a group common control resource allocated to a set of UEs that includes the UE, identifying a hashing function assigned to the UE for detecting control messaging communicated via the group common control resource that is addressed to the UE, receiving, via the group common control resource, a control message indicating addressing data and a bitmap, and processing the addressing data using the hashing function and the bitmap to determine applicability of the control message to the UE.

Abstract: Wireless communications systems and methods related to downlink (DL) control channel communications are provided. A wireless communication device identifies a search space set including a plurality of PDCCH candidate search spaces for a downlink control channel. The wireless communication device determines that a first resource associated with a first PDCCH candidate search space of the plurality of PDCCH candidate search spaces overlaps with a preconfigured resource. The wireless communication device monitors for a downlink control message over the downlink control channel by excluding monitoring in at least the first PDCCH candidate search space based on the determining.

Abstract: Methods, systems, and devices for wireless communications are described. Some wireless communications systems may support the transmission of a scheduling request via a physical sidelink feedback channel (PSFCH). In some cases, a user equipment (UE) may determine a configuration of a set of PSFCH resource blocks (RBs). The UE may receive a first bit map that may indicate a subset of the set of PSFCH RBs allocated for transmitting a scheduling request on the PSFCH, and the UE may receive a second bit map that may indicate a second subset of the PSFCH RBs allocated for hybrid automatic repeat request (HARQ) messages. The UE may transmit a scheduling request via one or more RBs of the first subset of the PSFCH RBs. In some cases, the UE may generate a waveform for transmitting the scheduling request message, and the waveform may be based on the number of RBs selected.

Abstract: Certain aspects of the present disclosure provide techniques for beam pair selection. A method that may be performed by a user equipment (UE) includes receiving, from a base station (BS), an indication to report one or more beam pairs to be used for full-duplex (FD) communication based on a timing constraint, wherein the timing constraint comprises a constraint on a time difference between receptions, at the UE, of a downlink (DL) signal and an uplink (UL) signal for each of the one or more beam pairs and transmitting a report specifying the one or more beam pairs in accordance with the indication, in accordance with aspects of the present disclosure.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may determine that a serving base station of the UE has obtained access to a wireless channel of a shared radio frequency spectrum band during a transmission opportunity that is separate from a scheduled uplink transmission by the UE. The UE may perform, based at least in part on the determination, a clear channel assessment (CCA) procedure on the wireless channel during a designated quiet portion of the transmission opportunity. The UE may transmit an unsolicited CCA status report to the serving base station during the transmission opportunity based at least in part on the CCA procedure.

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 (BS), information identifying a core resource set (CORESET) for one or more shared radio frequency spectrum channels. The CORESET may be configured into a plurality of resource blocks based at least in part on a resource block granularity associated with the one or more shared radio frequency spectrum channels. The UE may communicate with the BS using the CORESET. Numerous other aspects are provided.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a wireless communication device may determine that a threshold is satisfied with regard to a search space set mapping, for a plurality of search space sets, for a slot of a downlink control channel, wherein the threshold relates to at least one of: a slot-based control channel element limit, or a slot-based blind decode limit; and perform a mapping of or monitor a subset of search space set occasions, of a search space set of the plurality of search space sets, in the slot in connection with determining that the threshold is satisfied. Numerous other aspects are provided.

Abstract: Methods, systems, and devices for wireless communications are described. In some systems, transmissions from a neighboring base station may interfere with downlink transmissions from a serving base station to a target user equipment (UE). To coordinate interference between the base stations (e.g., mitigate interference, stabilize interference, etc.), the serving base station may generate an interference coordination message and may transmit the message over-the-air (OTA) to one or more neighboring base stations. The message may include parameters indicating a coordination scheme for the neighboring base station(s) to use for modifying one or more scheduling decisions. The coordination scheme may be configured or dynamically selected and may include interfering beam fixation, interfering beam suppression, or interfering beam avoidance. A neighboring base station receiving the OTA interference coordination message may modify a scheduling decision to mitigate or stabilize interference when the serving base station is transmitting to the target UE.

Abstract: Methods, systems, and devices for wireless communications are described. A base station may determine a degradation of a communication beam associated with a user equipment (UE). The base station may transmit a first signal identifying a beam switch occasion for the UE. The UE may receive a second signal identifying the beam switch occasion based on an outcome of the contention-based procedure. In some cases, the UE may transmit a third signal acknowledging the beam switch occasion during an acknowledgment opportunity based on the second signal, and may perform a beam switch during the beam switch occasion based on transmitting the third signal.
