Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine whether a sidelink to another UE is inactive, and disable the sidelink based at least in part on determining that the sidelink is inactive. Numerous other aspects are provided.

Abstract: In the examples described herein, a user equipment (UE) may identify multiple carriers configured for communications with a base station, and the UE may group the carriers into one or more preferred groups for synchronized scheduling at the base station. The preferred groups of carriers for synchronized scheduling may represent a recommendation that carriers within a preferred group are to be scheduled for communications with the base station on at least partially overlapping resources to maximize power savings at the UE. The UE may transmit an indication of the preferred groups of carriers to the base station, and the base station may identify an actual group of carriers for synchronized scheduling based on the indication received from the UE. The base station may then schedule communications with the UE based on the actual group of carriers.

Abstract: Some techniques and apparatuses described herein permit a user equipment (UE) to transition among different power configurations, which include different values for different power parameters, that impact an amount of power consumed by the UE. In some aspects, these transitions may be signaled by a base station based at least in part on traffic volume for the UE, which may assist with improving throughput and/or extending battery life of the UE. Furthermore, these transitions may be signaled dynamically, such as in downlink control information (DCI) and/or a medium access control (MAC) control element (CE) MAC-CE, which may conserve battery power and/or network resources as compared to reconfiguring the UE using an RRC message, and which may allow the UE to be reconfigured quickly as conditions associated with the UE change.

Abstract: Certain aspects of the present disclosure provide a technique for signaling user equipment (UE) assistance information (UAI) that is specific to a particular cell group (CG) (e.g., a secondary CG (SCG)). For example, the technique may be executed to generate CG specific UAI, which may indicate a configuration parameter for the UE when operating in a multiple radio dual connectivity (MR-DC) mode. The UE may signal the UAI to a network entity along with an indication of the CG to which the UAI is to be applied.

Abstract: The present disclosure provides systems, methods, and apparatuses for maintaining continuity of a buffer status report (BSR) from a user equipment (UE) when the UE is handed over between base stations. In one aspect, a base station or a component thereof may be configured to allocate a set of resources for transmission by a UE. The set of resources may have a capacity that is insufficient for an amount of data indicated by a BSR from the UE. The base station or component thereof may be further configured to transmit, to another base station in association with handover of the UE, an indication that the capacity of the set of resources is insufficient for the amount of the data indicated by the BSR.

Abstract: Certain aspects of the present disclosure provide techniques for sending uplink control information. A method that may be performed by a user equipment (UE) includes receiving an uplink grant for transmission on a plurality of physical uplink shared channels (PUSCHs), the plurality of PUSCHs being located on different component carriers (CCs); identifying one or more PUSCHs of the plurality of PUSCHs on which uplink control information (UCI) can be transmitted in a slot; assigning PUSCH data to the one or more identified PUSCHs on which the UCI can be transmitted before assigning PUSCH data to remaining PUSCHs of the plurality of PUSCHs; and transmitting the UCI and the PUSCH data in the slot on the assigned PUSCHs.

Abstract: Certain aspects of the present disclosure provide techniques for performing radio link monitoring (RLM) and radio link failure procedures in multiple-TRP (mTRP) communications, wherein the first TRP is part of a first cell group comprising the first TRP and one or more additional TRPs. The techniques include a method of wireless communication by a user equipment (UE), comprising establishing a plurality of radio links between the UE and a first transmission reception point (TRP) and a second TRP, determining an RLM resource of a first radio link of the plurality of radio links, monitoring the first radio link according to the determined RLM resource, detecting an RLF of the first radio link, determining that the first TRP is associated with the RLF of the first radio link based on the RLM resource of the first radio link, and transmitting an RLF notification indicating the RLF of the first radio link.

Abstract: Certain aspects of the present disclosure provide techniques for validation rules for message transmission occasions. In some cases, a user equipment (UE) may select a random access message transmission occasion for a preamble and a payload of a random access message, wherein the random access message transmission occasion comprises a preamble occasion and a payload occasion, select a preamble sequence for the preamble to transmit in the preamble occasion of the random access message transmission occasion of a two-step random access channel (RACH) procedure, select at least one resource unit (RU) for transmitting the payload in the payload occasion, validate the selected random access message transmission occasion based on one or more criteria, and transmit the preamble sequence and the payload in the selected message transmission occasion if the selected random access message transmission occasion is validated.

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: Certain aspects of the present disclosure provide techniques for an enhanced query and response message for a recommended bit rate for uplink and/or downlink streaming. The techniques generally include generating a query message indicating a requested data rate for streaming services, wherein the requested data rate is indicated via a bit rate field and one or more additional bits, and sending the query message to a base station.
