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: This disclosure provides systems, methods and apparatus, including computer programs encoded on computer storage media, for a scheduled entity to communicate within a wireless communication network. In one aspect, the scheduled entity receives a plurality of neighbor cell measurement relaxation mechanisms from a scheduling entity. The scheduled entity determines one or more channel condition parameters and selects one or more of the pluralities of neighbor cell measurement relaxation mechanisms, based on the determined one or more channel condition parameters. The scheduled entity executes measurement of one or more neighbor cells using the selected one or more neighbor cell measurement relaxation mechanisms.

Abstract: Certain aspects of the present disclosure provide techniques for power savings for reduced capability devices. A method that may be performed by a user equipment (UE) includes receiving a shared bandwidth part (BWP) configuration and a group common BWP configuration. The group common BWP configuration indicates a group common BWP shared by a group of UEs, including the UE, having one or more common capabilities or a common UE type. The method includes communicating using the group common BWP based on the group common BWP configuration.

Abstract: Methods, systems, and devices for wireless communication are described. Generally, the described techniques provide for efficiently signaling configurations of physical resources and transmission parameters to a user equipment (UE) for small data transmissions (for example, data transmissions in an inactive or idle state). A base station may broadcast or multicast downlink control information (DCI) in one or more control channels that schedules data transmissions in a set of data channels. The base station may then multicast one or more configurations in each of the data channels, and a UE may decode one of the data channels to determine a configuration for a small data transmission. Because the configurations may be transmitted in the data channels in addition to system information or paging information, a base station may have access to sufficient resources to provide suitable configurations to a UE for communications in an inactive or idle state.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive switching information to switch from utilizing a first sidelink bandwidth part (SL-BWP) to utilizing a second SL-BWP, the first SL-BWP and the second SL-BWP being configured for sidelink communications. The UE may transmit or receive data associated with a sidelink communication based at least in part on the switching information. Numerous other aspects are provided.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may selectively monitor, based at least in part on a configuration of the UE, a cell of a first discontinuous reception (DRX) group for a wake-up signal (WUS); and selectively start, during a DRX cycle of the first DRX group associated with the WUS, a DRX on duration timer for a second DRX group based at least in part on the WUS and whether the second DRX group has a DRX on duration occasion during the DRX cycle of the first DRX group. Numerous other aspects are provided.

Abstract: Fallback procedures for user equipments (UEs) are described that provide efficient fallback to a four-step random access procedure from a two-step random access procedure. For example, after transmitting a first message of a two-step random access procedure, a UE may start a fallback timer or counter and monitor for a second message of the two-step random access procedure for the duration of the fallback timer or counter. At the expiration of the fallback timer or counter, the UE may fall back to a four-step random access procedure. In some cases, the UE may transmit multiple repetitions of the first message and monitor for responses after transmitting the repetitions or after each repetition. Additionally, or alternatively, the base station may transmit an explicit signal to the UE that may signal to the UE to perform a fallback procedure at a beginning or middle of a random access procedure.

Abstract: In some aspects, a user equipment (UE) determines a transmission gap adjustment (TGA) for a first message (msgA) of a 2 step random access channel (RACH) procedure based on measurement of a reference signal transmitted by a base station as well as the radio resource configuration (RRC) configurations for msgA. In other aspects, a base station transmits a system information block (SIB) or RRC signaling that indicates at least one possible configuration of the TGA, and UEs determine the TGA depending on RRC state. Connected mode UEs having a timing alignment (TA) timer running may determine the TGA based on a previous TA. UEs in other RRC modes determine the TGA based on the possible configuration transmitted in the SIB or RRC signaling. Advantageously, 2 step RACH UEs are able to communicate with the base station without the closed loop TA information provided by a 4 step RACH.
