Abstract: Wireless communications systems and methods related to communicating control information are provided. A method of wireless communication performed by a first sidelink user equipment (UE) may include transmitting, to a second sidelink UE, a first sidelink synchronization block (S-SSB) in a scheduled S-SSB slot, performing a first listen-before-talk (LBT) procedure in an unlicensed frequency band, and transmitting, to the second sidelink UE, a second S-SSB in a slot before a next scheduled S-SSB slot based on the first LBT procedure being unsuccessful.

Abstract: Methods, systems, and devices for wireless communication are described. A user equipment may receive an indication of a pre-paging signal configuration for reception of a pre-paging signal associated with a first cell. The UE may monitor for the pre-paging signal from the first cell in response to one or more conditions being satisfied, the one or more conditions based at least in part on the pre-paging signal configuration. In some examples, the UE may receive, based on the monitoring, the pre-paging signal from the first cell, and the UE may output an alert message associated with receiving the pre-paging signal, the alert message indicating for the UE to be relocated to improve coverage.

Abstract: Some techniques described herein provide autonomous modification of a modulation and coding scheme (MCS) of a grant for a transmission by a user equipment UE. For example, the UE may receive a grant (e.g., a configured grant) indicating a resource allocation and a first MCS for a transmission on the resource allocation. The UE may use the resource allocation for a transmission of a number of transport blocks (e.g., one or more transport blocks), and may use a second MCS, different than the first MCS, for the transmission. In some examples, the second MCS may be a lower MCS, associated with a lower modulation scheme and/or code rate, than the first MCS. Thus, a per-resource-block power consumption of the transmission is decreased by using the second MCS, which provides power savings while reducing or eliminating padding of the uplink communication.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from a network entity, a configuration that indicates a time alignment timer associated with a timing advance group (TAG) for a bandwidth part (BWP) or a component carrier (CC) configured for multiple downlink control information (multi-DCI) based multiple transmission reception point (multi-TRP) communications. The UE may start the time alignment timer for a TRP. The UE may flush one or more hybrid automatic repeat request (HARQ) identifiers (IDs) from a HARQ buffer associated with the TRP based at least in part on an expiration of the time alignment timer. Numerous other aspects are described.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a sidelink configuration that indicates a set of sidelink slots comprising a first subset of sidelink slots to be used for first transmissions of sidelink communications and a second subset of sidelink slots to be used for second transmissions of the sidelink communications. The UE may communicate based at least in part on the sidelink configuration. Numerous other aspects are described.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may transmit an indication of a capability of the UE to receive downlink transmissions over a plurality of component carriers with a first quantity of antennas. The UE may receive, in accordance with the indication of the capability of the UE, the downlink transmissions with at least a subset of the first quantity of antennas and over at least a subset of the plurality of component carriers.

Abstract: Methods, systems, and devices for wireless communications are described in which multiple devices may implement sidelink communications for direct device-to-device exchange of information. Such devices (e.g., user equipment (UE) devices) may be configured with resources for sidelink communications, and may monitor for a sidelink preemption indication (SPI) from a base station and determine whether one or more sidelink communications is preempted based on the SPI. The sidelink communications may include a feedback communication that is transmitted using sidelink feedback resources. Based on an indication in a received SPI, it may be determined whether or not to transmit sidelink feedback. The sidelink feedback may be transmitted to one or more other sidelink devices, or to a base station, and preemption of the sidelink feedback may be determined based on one or more parameters associated with the sidelink communications, associated with the SPI, or any combinations thereof.

In some aspects, a user equipment (UE) may receive configuration information for a serving cell associated with a first transmission reception point (TRP) and for two or more other cells associated with two or more other TRPs, the serving cell and the two or more other cells associated with a same component carrier. The UE may receive a first timing advance configuration associated with the serving cell and a second one or more timing advance configurations associated with the two or more other cells. The UE may transmit an uplink communication in accordance with the first timing advance configuration or the second one or more timing advance configurations. Numerous other aspects are provided.

Abstract: Methods, systems, and devices for wireless communication at a user equipment (UE) are described. A UE may establish communication with a set of transmission reception points including a first transmission reception point and a second transmission reception point. The UE may receive a single control message including one or more respective timing advance indications for uplink channel transmissions to one or more respective transmission reception points. In some examples, each timing advance indication may identify a respective transmission reception point using a respective timing advance value. The UE may determine a first timing advance value for the uplink channel transmissions based on the one or more respective timing advance indications identifying a respective transmission reception point. The UE may then transmit, to the first transmission reception point, an uplink channel transmission over an uplink channel using the first timing advance value determined for the first transmission reception point.

Abstract: Certain aspects of the present disclosure provide techniques for configuring a user equipment (UE) to communicate with a network entity based on a selected antenna panel reported to a network entity. An example method generally includes transmitting, to a network entity, a report including information associated with an antenna panel selected for communications between the user equipment and the network entity; selecting a starting time and a wait time to apply a configuration associated with the selected antenna panel; activating an update timer based on the starting time and the wait time; and communicating with the network entity based on the configuration associated with the selected antenna panel after expiry of the update timer.
