Abstract: Methods, systems, and devices for wireless communications are described. An access point (AP) may configure power parameters for sidelink communications between user equipments (UEs). The power parameters may be configured based on the UEs operating within an AP service area. In some examples, an AP may transmit one or more signals to the first UE, and the first UE may determine the power parameters based on receiving the signals. Additionally or alternatively, the first UE may be configured to transmit one or more reference signals to the AP, and the AP may configure the power parameters based on receiving the reference signals. The first AP may indicate the power parameters in a sidelink configuration transmitted to the first UE. The first UE may communicate with the second UE on a sidelink channel in accordance with the sidelink configuration, which may improve efficiency and reliability of the sidelink communications.

Abstract: Methods, systems, and devices for wireless communications are described. A device may identify a transport block (TB) size for a TB that is scheduled across a set of component carriers (CCs) including a first CC and a second CC. The TB may include a first code block (CB) and a second CB. The device may rate match the TB with the set of CCs. Based on the rate matching, the device may identify redundancy portions of the first CB and redundancy portions of the second CB. The device may allocate a first redundancy portion of the first CB and a first redundancy portion of the second CB to the first CC, and may allocate a second redundancy portion of the first CB and a second redundancy portion of the second CB to the second CC. The device may transmit the TB over the set of CCs based on the allocating.

Abstract: Methods, systems, and devices for wireless communication are described that provide for reduced timing between certain downlink communications and responsive uplink communications relative to certain legacy systems (e.g., legacy LTE systems). A user equipment (UE) or base station may be capable of operating using two or more timing configurations that each include an associated time period between receipt of a downlink communication (e.g., a grant of uplink resources or shared channel data) and a responsive uplink communication (e.g., an uplink transmission using the granted uplink resources or feedback of successful reception of the shared channel data). In cases where a UE or base station are capable of two or more timing configurations, a timing configuration for a transmission may be determined and the responsive uplink communication transmitted according to the determined timing configuration.

Abstract: Methods, systems, and devices for wireless communications are described for prioritization of sidelink communications of a user equipment (UE) with one or more access link communications. A prioritization scheme may provide inter-UE and intra-UE prioritization that may be used to prioritize sidelink communications and one or more access link communications. Inter-UE prioritization may be used at the UE to determine whether to cancel all or a portion of a sidelink communication that uses resources indicated in a cancellation indication from a base station, or to transmit the sidelink communication irrespective of the cancellation indication. Intra-UE prioritization may be used at the UE to determine which of one or more access link communications or a sidelink communication is to be maintained or canceled in the event of overlapping resources between the access link and sidelink communications.

Abstract: Methods, systems, and devices for wireless communications are described. Aspects of the disclosure describe using sidelink resources to identify possible interference (e.g., including cross-link interference) in a first resources used for communications between a base station and a user equipment (UE). With such techniques, a base station may transmit a conditional grant to a UE that schedules resources for the UE to use to communicate with the base station (e.g., either uplink or downlink). The UE may monitor sidelink resources to identify an indication of interference for the resources scheduled by the conditional grant. Different UEs may exchange messages or may transmit energy over the sidelink network to indicate resources are being used to communicate between base stations and UEs. The UE may transmit an acknowledgement or a negative acknowledgement to the base station indicating whether the resources scheduled by the conditional grant are to be used by the UE.

Abstract: Disclosed are techniques for wireless communication. In an aspect, a user equipment (UE) receives a sounding reference signal (SRS) resource configuration, the SRS resource configuration indicating at least a comb pattern for at least one SRS resource allocated to the UE and a puncturing unit for the comb pattern, wherein the comb pattern is divided into one or more puncturing units, wherein each puncturing unit comprises one or more time units of the comb pattern, and wherein each of the one or more time units comprises two or more symbols, and refrains from transmitting all SRS transmissions of the at least one SRS resource within a first puncturing unit of the one or more puncturing units based on a determination that one or more SRS transmissions of the at least one SRS resource within the first puncturing unit are to be dropped.

Abstract: Methods, systems, and devices for wireless communications are described. A first wireless device, such as a user equipment (UE), may be configured to communicate with one or more other wireless devices (e.g., another UE) via sidelink communications. The first wireless device may receive an indication of a schedule of resources for sidelink communications to be performed over a communication beam, the schedule indicating a set of resources corresponding to a beam configuration for the sidelink communications with a second wireless device. The first wireless device may communicate with the second wireless device via one or more sidelink channels based on configuring the communication beam using the beam configuration over the set of resources. In some examples, the indication of the schedule of resources may be received in a confirmation of the schedule established by the second wireless device or, in some examples, in a request to establish the schedule.

Abstract: Methods, systems, and devices for wireless communications are described. A first user equipment (UE) may belong to a group of UEs that includes at least a second UE and a third UE. The first UE may perform a channel access procedure and, when the channel access procedure is successful, may transmit a first positioning reference signal (PRS) over a sidelink communication link to the second and third UEs. The first UE may transmit the first PRS during a first time interval of a transmission window. Based on receiving the first PRS, the second UE may perform a channel access procedure and may transmit a second PRS to the first UE during a second time interval of the transmission window. The second PRS may be multiplexed (e.g., using frequency division multiplexing (FDM) or code division multiplexing (CDM)) with at least a third PRS transmitted by the third UE.

Abstract: Configurations for configured grant (CG) in new radio unlicensed (NR-U) systems is disclosed. CG configurations may, based on a periodicity, be provided either using a bitmap, shorter periodicity, or resource indicator value (RIV) signaling of start/end symbols, longer periodicity. Such CG configurations configure M sets of time division resource allocations. CG configuration may include common start/end symbols from for all contiguous allocations in one configuration. Common LBT starting points may be defined for all configured slots as indicated through a bitmap. The CG configuration allows for mini- and full slot configurations, in which the mini-slots are configured within the already configured CG slots. Repetition configurations include a type 1 for coverage and a type 2 for faster retransmission and reduced downlink feedback information (DFI) overhead. With multiple UEs, a UE identifier is added to the uplink control information (UCI). UEs may further ramp up power in the absence of DFI.
