Abstract: Aspects presented herein provide an enhanced power management solution, such that an apparatus may configure a UE with more than one DRX configuration for different cells. The apparatus determines a configuration of a plurality of discontinuous reception (DRX) groups for communicating with a UE. The apparatus configures the UE with a first DRX group for a first set of serving cells. The apparatus configures the UE with a second DRX group for a second set of serving cells.

Abstract: The present disclosure provides for proactive wake-up beam management for connected mode discontinuous reception (C-DRX) operation. For example, a user equipment (UE) monitor one or more synchronization signal blocks (SSBs) or reference signals received associated with a set of wake-up beams from a network entity. The UE may further determine that the set of wake-up beams satisfies a distress condition. The UE may additionally transmit a distress indication to the network entity based on determining that the set of wake-up beams satisfies the distress condition. Aspects described herein also provide a network entity that receives a distress indication from the UE in response to transmitting a set of wake-up beams and transmits a subsequent set of wake-up beams having at least one wake-up beam different not included in the set of wake-up beams to the UE.

Abstract: Methods, systems, and devices for wireless communications are described. Generally, the described techniques provide for a user equipment (UE) to determine a time gap between receiving a paging early indication (PEI) and receiving a paging message based on a link quality of the UE. The UE may determine the time gap based on a number of reference signals the UE may measure after receiving the PEI to obtain channel information for accurately decoding a forthcoming paging message and a periodicity of the reference signals. The UE may transmit UE assistance information (UAI) to the base station during an active state to indicate the time gap. The UE may receive a configuration message from the base station indicating a configured time gap for the UE based on the UAI. The UE may receive the PEI and monitor a paging occasion for the paging message according to the configured time gap.

Abstract: Methods, systems, and devices for wireless communications are described in which a user equipment (UE) may be configured for discontinuous reception (DRX) operations using wakeup signals. The UE may monitor periodic wakeup signal occasions for wakeup signals and, in the event that the UE detects a wakeup indication that the UE is to initiate an active duration, the UE may power on transmit/receive circuitry for communications with a base station. In an absence of receiving the wakeup indication, the UE may be configured to transmit an uplink reference signal (e.g., a sounding reference signal) to the base station in an inactive duration of a DRX cycle in some cases. The uplink reference signal may be measured at the base station and used to determine one or more parameters for subsequent communications with the UE.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may establish a connection with a base station based at least in part on a synchronization signal block from the base station, wherein the synchronization signal block comprises at least a first synchronization signal. The UE may identify a configuration for a transmission pattern for the first synchronization signal to be transmitted by the base station. The UE may receive one or more instances of the first synchronization signal according to the transmission pattern for the first synchronization signal. The UE may modify the established connection with the base station based at least in part on the received one or more instances of the first synchronization signal.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may transmit to a base station (BS), information indicating a medium access control (MAC) security capability of the UE. The UE may receive from the BS, a communication that includes an indication of a MAC security configuration for communications between the UE and the BS. The indication of the MAC security configuration may be based at least in part on the MAC security capability of the UE. Numerous other aspects are provided.

Abstract: Methods, systems, and devices for wireless communications are described for configuring discontinuous reception (DRX) cycles within a DRX time period at a user equipment (UE). DRX configurations may provide that different DRX cycles have non-uniform cycle durations within the DRX time period. Such non-uniform cycle durations may provide DRX ON-durations that are aligned with a periodicity of downlink traffic to the UE in which the downlink traffic may be unaligned with timing boundaries used for wireless communications between the UE and a base station, such as slot boundaries or symbol boundaries.

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: Generally, the described techniques provide for a user equipment (UE) generating a scheduling request (SR) for a set of data for an uplink transmission from the UE to a base station. The UE may determine whether the SR for the set of data is associated with a grant-free configuration for the UE. The grant-free configuration may indicate a set of time-frequency resources that the UE may use to transmit the set of data. The UE may transmit to the base station an indication of whether the SR is associated with the grant-free configuration. If the SR is associated with a grant-free configuration for the UE, the UE may use the corresponding resources to transmit the set of data to the base station, and the base station may then decode the data based on having received the indication of the resources by way of the grant-free configuration.
