Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a wireless communication device may transmit an announcement that indicates a plurality of future resource reservations. The wireless communication device may transmit multiple sets of announcements that indicate one or more reservations and may vary the transmission frequency thereof based on proximity to the communications. The wireless communication device may transmit an announcement that indicates a future communication and a cancellation indication that indicates a cancellation of the communication. The wireless communication device may transmit a preemption indication that indicates that resources reserved for an announced future communication have been preempted for another communication. Numerous other aspects are described.

Abstract: Apparatus, methods, and computer-readable media for facilitating sidelink resource pool activation and deactivation for sidelink communication are disclosed herein. An example method for wireless communication at a first sidelink device includes identifying a configuration of a bandwidth part (BWP) for sidelink communication. In some examples, the BWP may comprise at least a first resource pool including a first subset of frequency resources and a second resource pool including a second subset of frequency resources. The example method also includes receiving an activation indication activating the second subset of frequency resources of the second resource pool. Additionally, the example method includes activating the second subset of frequency resources of the second resource pool based on the activation indication.

Abstract: Methods, systems, devices, and apparatuses for wireless communications that support transmission diversity enhancement for uplink control channel are described. Generally, the described techniques provide for enhanced performance of an uplink control channel such as a physical uplink control channel (PUCCH) through the use of transmission diversity. In some cases, multiple input multiple output (MIMO) techniques may be supported for transmission of an uplink control channel for a given format suitable for transmission diversity enhancement. A resource block (RB) used in an uplink control channel transmission may contain a number of resource elements (REs) across one or more resource blocks. According to some aspects, a transmit diversity scheme may be employed at the RE level through application of different spatial precoders for different groups of REs of a given RB.

Abstract: Certain aspects of the present disclosure provide techniques for signaling a user equipment (UE) to put a sidelink (SL) component carrier (CC) into dormancy or take the SL CC out of dormancy, such as mode 1 or mode 2 sidelink communications. In one example, a method performed by a UE includes receiving an indication to put a first CC into dormancy; and putting an SL CC into a dormant state in response to the indication. In another example, a method includes transmitting an indication that the first UE will put an SL CC into a dormant state; and receiving an acknowledgment (ACK) of the indication.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive an indication of a resource configuration for a random access (RA) procedure. The resource configuration may identify multiple sets of transmission resources corresponding to multiple radio resource control (RRC) states. The UE may identify an RRC state and may determine a set of transmission resources and/or a transport format based on the indication of the resource configuration, the identified RRC state, and/or a UE identifier (UE ID). The UE may transmit a first RA procedure message (e.g., a msgA) using the determined transmission resources and/or transport format. The base station may receive the message and may identify the RRC state of the UE based on the first message and transmitted indication of the resource configuration. The base station may transmit a second RA procedure message (e.g., a msgB), which the UE may receive.

Abstract: A method, apparatus, or computer-readable medium with instructions for beam management for radio frequency (RF) sensing at a wireless device. The wireless device performs a first beamsweep of an RF signal and measures a reflection of the RF signal based on the first beamsweep. The wireless device performs a second beamsweep of the RF signal, wherein the first beamsweep is based on a different parameter than the second beamsweep and measures the reflection of the RF signal based on the second beamsweep. The wireless device selects a beam for RF sensing based on the first beamsweep and the second beamsweep.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from a base station and while in a low-power mode, a reference signal, where the reference signal is not a cell-specific reference signal. Additionally, or alternatively, the UE may receive a signal including at least one parameter associated with the reference signal. Accordingly, the UE may initiate, with the base station, a random access procedure based at least in part on measurements of the reference signal. In some aspects, the UE may initiate the random access procedure by transmitting, to the base station, a random access preamble based at least in part on the at least one parameter. Numerous other aspects are provided.
