Abstract: Methods, systems, and devices for wireless communications are described. In some examples, a base station may send signaling to multiple user equipments (UEs) indicating for the UEs to switch to a radio frequency bandwidth. The UEs may operate according to a reduced set of communication operations in accordance with the radio frequency bandwidth. For example, the UEs may refrain from monitoring one or more channels, may not transmit on one or more channels, or the like. The UEs may switch out of the radio frequency bandwidth based on a trigger event, such as a timer expiring, receiving an indication in a downlink control information (DCI) message, or the like.

Abstract: In a legacy gNB (e.g., pre-Rel. 17 gNB), RC UEs with only 1 or 2 receive antennas may have a geographic coverage area for control data and traffic data that is smaller than their geographic coverage area for SSB with respect to certain legacy gNBs. By contrast, at least some new gNBs (e.g., Rel. 17+ gNBs) have the capability to provide uniform geographic coverage for RC UEs with respect to SSB, control data and traffic data. In an aspect of the disclosure, a particular class of UEs (such as RC UEs) is steered towards particular cells (e.g., Rel. 17+ gNBs) via one or more biased class-specific cell selection parameters included in system information from the cells.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a system information block (SIB) indicating a plurality of subband configurations. The UE may identify, based at least in part on one or more of the plurality of subband configurations, one or more uplink subbands in a time division duplexing (TDD) component carrier and one or more downlink subbands in the TDD component carrier. The one or more uplink subbands and the one or more downlink subbands may be frequency division duplexed within the TDD component carrier. Numerous other aspects are provided.

Abstract: Methods, systems, nodes, and devices for wireless communication are described. The method may include a first network node (e.g., a user equipment (UE)) receiving a first message that indicates a first preamble and transmitting a random access request message indicative of a request by the first network node for repetition based transmission of a second message. In response to the random access request, the first network node may receive a random access response message including an indication that the second message is to be transmitted with repetition and transmit the second message in accordance with repetition.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may identify one or more radio frequency (RF) spectrum bands for full-duplex communications, and may signal an indication of the UE's capability to support full-duplex communications for each RF spectrum band. The UE may further receive one or more configurations for full-duplex communications, which, in some examples, may be based on the UE's indicated capabilities. As an example, the UE may identify a guard band configuration for full-duplex communications, where the guard band configuration may be based on one or more aspects of resources used for the full-duplex communications. In other cases, the UE may identify a transmission hopping or antenna switching configuration for full-duplex communications. In any case, the UE may communicate with a base station in accordance with the one or more configurations and the UE's capabilities.

Abstract: Aspects presented herein may enable a UE to determine whether phase continuity is to be maintained for one or more uplink transmissions when the UE is configured with a frequency-hopping with zero frequency offset. In one aspect, a UE receives, from a network entity, an indication of frequency hopping with zero frequency offset. The UE determines whether phase continuity is to be applied to UL transmissions based on the indication of the frequency hopping with zero frequency offset. The UE transmits, to the network entity, at least one uplink channel with no phase continuity based on the determination to not apply phase continuity to the UL transmissions.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may be configured to receive, from a base station, control signaling indicating a proactive traffic reporting configuration identifying a trigger condition for proactively reporting expected data traffic for the UE. The UE may transmit, to the base station based on a satisfaction of the trigger condition, an uplink message including an indication of an expected amount of data traffic for the UE, where the satisfaction of the trigger condition is based on the expected amount of data traffic. The UE may subsequently receive, in response to the uplink message, a downlink message indicating a resource allocated for communicating the expected amount of data traffic, and may communicate at least a portion of the expected amount of data traffic with the base station via the indicated resource.

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: This disclosure provides systems, methods, and apparatuses for a user equipment (UE) to activate a bandwidth part (BWP) during a dual active protocol stack (DAPS) handover with a supplementary uplink (SUL). In one aspect, a base station may receive an indication that the UE supports DAPS handover. The base station may transmit a configuration or an instruction that indicates an active BWP for the UE to use for a target cell or target master cell group (MCG). In another aspect, the UE may transmit on a normal uplink (NUL) in an active BWP for a NUL carrier and transmit on a SUL in an active BWP for a SUL carrier. The UE may establish, in association with a DAPS handover being triggered, an active UL BWP that is within an active UL BWP for the NUL carrier or an active UL BWP for the SUL carrier.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine a number of repetitions of a message 3 (msg3) communication of a four-step random access channel (RACH) procedure that are to be transmitted to a base station. The UE may transmit, to the base station, the repetitions of the msg3 communication based at least in part on determining the number of the repetitions of the msg3 communication. Numerous other aspects are provided.
