Abstract: This disclosure provides systems, methods and apparatus, including computer programs encoded on computer storage media, for maintaining, between a user equipment (UE) and a component of a base station (BS), a mutual understanding of multiple sets of linked physical downlink control channel (PDCCH) candidates if some PDCCH candidates of the multiple sets of linked PDCCH candidates occupy a same set of resources. In one aspect, the UE may select to monitor one of the PDCCH candidates that occupy the same set of resources in accordance with a prioritization rule. Upon selecting one of the PDCCH candidates that occupy the same set of resources for monitoring by the UE, the UE and the component of the BS may select a reference PDCCH candidate for one or more of the multiple sets of PDCCH candidates in accordance with a reference selection rule.

Abstract: Aspects described herein relate to sidelink transmissions. In an example, a first user equipment (UE) may receive a multi-opportunity grant from a network entity, the multi-opportunity grant indicating multiple listen-before-talk (LBT) opportunities for scheduling a transmission between the first UE and a second UE; perform a LBT procedure for one or more slots of a plurality of slots indicated by the multiple LBT opportunities; select a first slot of the plurality of slots corresponding to an earliest available LBT based on performing the LBT procedure; and communicate a transmission to the second UE during the transmission time interval (TTI) of the first slot.

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.
