Abstract: Methods, systems, and devices for wireless communications are described. Multiple user equipments (UEs) may communicate as part of a sidelink communications system. The UEs may identify a frame for a sidelink connection. The frame may include a control portion and a data portion. One UE of a pair of UEs may receive a data signal from the other UE of the pair, and the data signal may be received in the data portion of the first instance of the frame and in the control portion of a second instance of the frame. Another pair of UEs may attempt to reserve a subsequent data portion by transmitting a request signal in the control portion in the second instance of the frame, and the second pair of UEs may receive a suppression signal from the first pair of UEs indicating ongoing data transmission by the first pair of UEs.

Abstract: Methods, systems, and devices for wireless communications are described. In one aspect, a first user equipment (UE) may transmit an indication of non-preferred resources to a second UE and an indication of an amount of transmit power reduction for the second UE to observe for a sidelink transmission on the non-preferred resources. In another aspect, a first UE may transmit an indication of an amount of transmit power reduction for a second UE to observe for a sidelink transmission on conflicting resources (e.g., resources reserved by the second UE and a third UE). Because the second UE may transmit on the non-preferred resources or the conflicting resources with reduced power (e.g., rather than suppressing transmissions on the non-preferred resources or the conflicting resources), the utilization of the non-preferred resources or the conflicting resources may be improved.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may identify that an uplink transmission to a base station is to occur in accordance with an uplink timing advance value representing an amount of time that the uplink transmission takes from transmission at the UE to reception at the base station. The UE may perform an autonomous open-loop adjustment to the uplink timing advance value. The UE may transmit the uplink transmission to the base station in accordance with the adjusted uplink timing advance value. The base station may transmit an indication of a set of uplink timing advance values for a UE to use for uplink transmissions, each of the set of uplink timing advance values representing an amount of time that an uplink transmission is expected to take from transmission at the UE to reception at the base station.

Abstract: Aspects of the present disclosure provide techniques for beam failure detection and related timing determinations, such as for applying a default beam after beam failure recovery response (BFRR) message. A method by a user equipment (UE) may include detecting failure of a beam associated with a first cell. The detecting can include performing beam failure detection (BFD) of a beam pair link (BPL) associated with the first cell (e.g., secondary cell (Scell)). The first cell can be in carrier aggregation (CA) with a second cell. The UE may send a beam failure recovery request (BFRQ) message on a second cell (e.g., a primary cell (Pcell)). The BFRQ message can include a candidate recovery beam for the first cell. The UE can receive a BFRR message on the second cell and determine a duration from reception of the BFRR message until using a default beam for communications on the first cell.

The UE may transmit, to the second UE using a beam included in the first beam group, a signal using one or more transmit parameters that are based at least in part on at least one of the first CBR or the second CBR. Numerous other aspects are described.

Abstract: Certain aspects of the present disclosure provide techniques for sidelink operation. A method that may be performed by a first user equipment (UE) includes generating at least one first message indicating a request for resource allocation for sidelink communication between the first UE and a second UE, transmitting the at least one message indicating the request for the resource allocation, receiving at least one second message allocating one or more first component carriers for the sidelink communication, and communicating with the second UE using the one or more first component carriers.

Abstract: Methods, systems, and devices for wireless communications are described. In some systems, a user equipment (UE) may perform path-loss estimation to support uplink transmit power control. The UE may perform path-loss estimations on path-loss reference signals configured by a base station. In some cases, the base station may update (e.g., activate, deactivate, or both) particular path-loss reference signals using a medium access control (MAC) control element (CE). The UE may determine which path-loss reference signal or signals to use for path-loss estimation based on one or more techniques. For example, the UE may filter path-loss measurements over a time duration or may use a single, unfiltered path-loss measurement for path-loss estimation. Additionally or alternatively, the UE may receive deactivated path-loss reference signals (e.g., for a set amount of time or for any amount of time) or may refrain from receiving deactivated path-loss reference signals.

In some aspects, a first user equipment (UE) may receive, from a second UE and via a receive beam of the first UE, an inter-UE coordination (IUC) request, wherein the IUC request is based at least in part on a transmit beam of the second UE that is associated with an intended transmission of the second UE. The UE may transmit, to the second UE, IUC information that indicates preferred resources or non-preferred resources for the intended transmission, wherein the IUC information is based at least in part on a channel sensing by the first UE. Numerous other aspects are described.

Numerous other aspects are described.
