Abstract: Methods, systems, and devices for wireless communications are described. In some implementations, a method for wireless communication at a user equipment (UE) is described that includes identifying that the UE is in carrier aggregation communication with a primary and secondary cell. The method may also include monitoring, during one or more time intervals, UE-specific search spaces of the secondary cell for control information scheduling data communications on the primary cell. The method may include switching, during one or more different time intervals, to monitoring UE-specific search spaces of the primary cell. Another method describes wireless communication at a base station that may configure a UE to communicate via carrier aggregation, transmit control information via the secondary cell to the UE during downlink TTIs, and transmit control information via the primary cell to the UE during uplink TTIs.

Abstract: Methods, systems, and devices for wireless communications are described. In some systems, a base station may configure a user equipment (UE) with a control resource set (CORESET) with multiple transmission configuration indicator (TCI) states. The UE may determine TCI state configurations for one or more search space sets associated with the CORESET, where different search space sets associated with the CORESET may have different TCI state configurations. For example, each search space set may be associated with a first TCI state of the CORESET, a second TCI state of the CORESET, or both. The UE may monitor for downlink control information (DCI) messages in physical downlink control channel (PDCCH) candidates of the search space sets according to respective TCI state configurations for the search space sets. Such a configuration may flexibly support a base station transmitting DCI using different TCI state configurations in PDCCH candidates of a single CORESET.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may monitor for downlink control information (DCI) among a plurality of physical downlink control channel (PDCCH) candidates that are associated with each other, the plurality of PDCCH candidates including at least a first PDCCH candidate in a first transmission time period and a last PDCCH candidate in a second transmission time period. The UE may identify a reference timing rule based at least in part on the association between the plurality of PDCCH candidates, the reference timing rule indicating that a reference time is to be determined based at least in part on either the first transmission time period or the second transmission time period. The UE may determine the reference time based at least in part on the reference timing rule and communicate based at least in part on the reference time.

Abstract: Methods, systems, and devices for wireless communication are described. Generally, the described techniques provide for a first user equipment (UE) to manage the reuse of resources reserved for sidelink communications by the UE. The first UE may identify scheduling information for a sidelink shared channel between the first UE and a second UE, and the first UE may reserve a set of resources for subsequent sidelink communications by the first UE. The first UE may transmit a sidelink control message indicating the scheduling information and the reserved resources to one or more neighboring UEs. The sidelink control message may include a reuse allowance indicator that may indicate whether the set of reserved resources is available for spatial reuse by the neighboring UEs. The neighboring UEs may determine whether the reuse the reserved resources based on the control message, the reuse allowance indicator, or both.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive, from a base station, a configuration message which includes one or more parameters pertaining to blind decoding attempts by the UE of repetition-based physical downlink control channel (PDCCH) candidates. The UE may determine, from the configuration message, a blind decoding count mode which indicates a process for counting a number of blind decoding attempts of repetition-based PDCCH candidates. The UE may monitor for one or more repetitions of a downlink control information by attempting to blind decode the one or more repetitions of a PDCCH candidate in accordance with a maximum blind decode count and the blind decoding count mode.

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.
