Abstract: Methods, systems, and devices for wireless communications are described. A UE may identify a configuration of sidelink synchronization signal block instances including a first quantity of sidelink synchronization signal block instances for each of a plurality of sidelink synchronization signal block periods. The UE may transmit a second quantity of sidelink synchronization signal block instances over a first sidelink synchronization signal block period. In some aspects, the UE may transmit a sidelink synchronization signal block burst using beams in a sidelink synchronization signal block period. The UE may identify a configuration for a set of resources of a sidelink beam selection resource pool based on transmitting the sidelink synchronization signal block burst. The UE may receive, from another UE over the set of resources, a control message including an indication of preferred beams. The UE may transmit the sidelink data to the other UE using the preferred beams.

Abstract: This disclosure provides methods, devices, and systems for resource selection supporting the identification of resources for receiving two-stage downlink control information (DCI). In some systems, for example, a base station may transmit a first stage DCI and a second stage DCI to a user equipment. The first stage DCI may include control information for a group of UEs including the UE and the second stage DCI may include control information that is specific to the UE. The UE may determine a resource to use for receiving the second stage DCI based on an indication in the first stage DCI. In some examples, the UE may determine a resource from a resource pool based on a resource selector included in the first stage DCI and receive the second stage DCI over the determined resource. The resource pool may be indicated by the first stage DCI or pre-configured at the UE.

Abstract: Certain aspects of the present disclosure provide techniques for differential power parameter reporting in multi-panel uplink transmission. A method that may be performed by a user equipment (UE) includes determining a first transmit power control parameter associated with a first panel of the UE and a differential transmit power control parameter to be used to indicate a second transmit power control parameter associated with a second panel of the UE, the differential transmit power control parameter indicating a difference between the first transmit power control parameter and the second transmit power control parameter generating a reporting message indicating the first transmit power control parameter and the differential transmit power control parameter; and transmitting the reporting message to a base station.

Abstract: Certain aspects of the present disclosure provide techniques for configuring sidelink slots without symbols for automatic gain control. One aspect provides a method for wireless communication by a user equipment, including receiving a first cyclic prefix of a first symbol within a slot at the user equipment. The method further includes configuring a first automatic gain control setting based on a received power in the first cyclic prefix of the first symbol, and receiving a data portion of the first symbol using the first automatic gain control setting.

Abstract: Certain aspects of the present disclosure provide techniques for enabling mini-slot detection in sidelink. A method performed by a user equipment (UE) includes receiving a sidelink configuration comprising a set of configuration parameters. The set of configuration parameters defines a plurality of sidelink mini-slots within a slot structure. The method may further include performing communications in one or more of the plurality of sidelink mini-slots.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment may receive information identifying a shared channel occupancy for a packet transmission resource; determine a range metric for die shared channel occupancy based at least in part on location information; determine whether to share the shared channel occupancy for packet transmission using the packet transmission resource based at least in part on the range metric; and selectively transmit one or more packets in the shared channel occupancy based at least in part on a result of determining whether to share the shared channel occupancy. Numerous other aspects are provided.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may transmit acknowledgment feedback for a combined signal derived from individual downlink signals received on respective radio links, where the acknowledgment feedback is transmitted with a phase shift applied to the transmission. In some cases, the phase shift may indicate which individual downlink signals were unsuccessfully received and decoded on the respective radio links. For example, the acknowledgment feedback message may include acknowledgment feedback for a final decoding of the combined signal on whether the combined signal is successfully received and decoded and side negative acknowledgment information indicating which individual radio links were unsuccessfully received and decoded via the phase shift. The UE may transmit the acknowledgment feedback on a strongest radio link, a subset of the radio links, or on all of the radio links.

Abstract: Aspects relate to techniques for signaling the capability of a wireless communication device (e.g., a UE) to support demodulation reference signal (DMRS) bundling for channel estimation across two or more slots in the sidelink or uplink. In some examples, a transmitting UE may transmit a DMRS bundling indication to a receiving device (e.g., a receiving UE for sidelink DMRS bundling or a base station for uplink DMRS bundling). The DMRS bundling indication may indicate a capability of the transmitting UE to support DMRS bundling. The transmitting UE may then transmit a respective set of DMRSs within each of two or more slots during a DMRS bundling window to the receiving device based on the transmitting wireless communication device and the receiving device supporting DMRS bundling.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a UE may receive an indication that a transmission of first data is to be modified and that second data is to be transmitted in place of a portion of the transmission of the first data; and identify a single time at which the transmission of the first data is to be canceled and transmission of the second data can begin, based at least in part on capabilities of the UE. Numerous other aspects are provided.
