Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may determine resource selection priority levels associated with available resources for sidelink signaling in an unlicensed radio frequency spectrum band, the resources selection priority levels may be determined based on resource reservation information of the available resources, a time domain location of the available resources, or both. For example, a first resource of the available resources may be associated with a higher priority than a second resource of the available resources in resource selection. The UE may select one or more resources for the sidelink signaling from the available resources based on the resource selection priority levels associated with the available resources. The UE may transmit the sidelink signaling on the unlicensed radio frequency spectrum band using the one or more selected resources.

Abstract: Aspects of the present disclosure provide techniques configuring half duplex UEs (HD-UEs) to implement supplementary downlink (SDL) in band combination that may be in same or different frequency range designations (e.g., FR1 or FR2). Particularly, in order to compensate for the loss of downlink coverage and improve load balancing, aspects of the present disclosure configure the UE to perform random-access channel (RACH), a procedure that is a shared channel used by wireless terminals to access the mobile network, on the anchor carrier in time division duplex (TDD) band and after initial access, the UE may be configured to switch to SDL to receive subsequent downlink signals.

Abstract: Certain aspects of the present disclosure provide techniques for configuring sidelink slots with multiple automatic gain control symbols. One aspect provides a method for wireless communication by a user equipment, including enabling a slot configuration comprising at least two symbols configured for use by a receiver for automatic gain control in preconfigured symbol locations within a slot, and transmitting the at least two symbols while transmitting symbols within the slot.

Abstract: Certain aspects of the present disclosure provide techniques for unlicensed channel occupancy time sharing based on received signal strength. A method that may be performed by a first user equipment (UE) includes receiving a first transmission from a second UE, the first transmission indicating the second UE has acquired a frequency band for a channel occupancy time (COT). The method may also include transmitting a signal within the frequency band during the COT in response to a signal strength of the first transmission as received by the first UE being greater than at least one threshold.

Abstract: Certain aspects of the present disclosure provide techniques for receiving an uplink cancelation indication (ULCI) with a number of bits that indicate resources on which one or more uplink channels are to be modified; determining, from at least two uplink transmission groups characterized by different spatial parameters, at least one uplink transmission group to which a received ULCI applies in a component charrier; and modifying the one or more uplink channels that belong to the determined uplink transmission group in accordance with the ULCI. For example, modifying the one or more uplink channels includes at least partially canceling the one or more uplink channels if the resources indicated in the ULCI overlap with the resources of the one or more uplink channels. The one or more uplink channels may include at least one of: one or more physical uplink shared channels (PUSCHs) or one or more PUSCH repetitions.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive, from a base station, a downlink control information (DCI) message associated with scheduling transmissions for the UE on a plurality of component carriers. The UE may determine, for at least a first component carrier of the plurality of component carriers, that a frequency resource allocation field of the DCI message comprises an indication of a value that is invalid for frequency resource allocation on the first component carrier. The UE may determine, based at least in part on the invalid indication and using a subset of fields of the DCI message corresponding to the first component carrier, that one or more component carriers of the plurality of component carriers are dormant.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment may determine respective sets of time domain resources that are to be used for multiple repetitions of an uplink control information transmission in multiple slots; and transmit one or more of the multiple repetitions using the respective sets of time domain resources, or one or more other resources, in the multiple slots based at least in part on determining the respective sets of time domain resources. Numerous other aspects are provided.

Abstract: Methods, systems, and devices for wireless communications are described. A first user equipment (UE) may determine that that the first UE is scheduled to transmit a control signal and a synchronization signal associated with a synchronization signal block. The first UE may transmit, to a second UE during a first set of symbols within a time period, the control signal associated with a sidelink communication. In some examples, the first UE may transmit, to the second UE during a symbol subsequent to the first set of symbols, the synchronization signal associated with the synchronization signal block, and may communicate with the second UE according to the transmitted control signal and the transmitted synchronization signal.

Abstract: Aspects relate to transmission of physical uplink control channel (PUCCH) information. A user equipment may receive a first physical downlink control channel (PDCCH) candidate carried by a control resource set that also carries a second PDCCH candidate, where these PDCCH candidates are associated with different aggregation levels. The user equipment may identify a PUCCH resource for transmission of information (e.g., an ACK or a NACK) that is associated with a physical downlink shared channel (PDSCH) transmission scheduled by the first PDCCH candidate. For example, the user equipment may identify the PUCCH resource based on a control channel element (CCE) index that corresponds to a starting CCE of the first PDCCH candidate and the second PDCCH candidate.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment may transmit, in a first slot within a channel occupancy time (COT), a first communication; determine whether one or more transmission criteria are satisfied for transmission of a second communication in a second slot within the COT; and selectively transmit the second communication in the second slot within the COT based at least in part on a result of determining whether the one or more transmission criteria are satisfied. Numerous other aspects are provided.
