Abstract: Aspects are provided which allow a base station to provide RACH configuration(s) indicating RACH occasions which correspond to wake up occasions of a base station according to a power savings mode of the base station. The base station sends one or more RACH configurations indicating ROs to a UE, and then monitors the ROs associated with the power savings mode. The UE determines the ROs associated with the power savings mode, and sends a wake up signal to the base station in at least one of the determined ROs. The base station obtains the wake up signal from the UE in at least one of the monitored ROs. Here, the wake up signal comprises a RACH message. As a result, network power consumption may be optimized through designed configurations which allow a UE to wake up a sleeping base station via a RACH message.

Abstract: Methods, systems, and devices for wireless communications are described. In some systems, a network node (e.g., a user equipment (UE)) may operate according to an operational state during which the network node is unavailable for communicating information. The network node may modify timing to account for the operational state. For example, a first network node (e.g., a UE) may receive, from a second network node (e.g., a network entity or base station), timing information corresponding to a timer. If a duration of the timer at least partially overlaps in time with a duration of the operational state for the first network node, the first network node may modify at least one of the timing information or the duration of the operational state. The first network node may communicate with the second network node in accordance with the modified timing information or the modified duration of the operational state.

Abstract: A user equipment (UE) may request to change its radio resource control (RRC) parameters by transmitting a UE assistance information message to a base station. However, the existing RRC parameters that a UE may request to change via a UE assistance information message may not be inadequate for some UEs and may cause a high signaling overhead. The aspects described herein include an apparatus that obtains configuration information for a UE assistance information message, the configuration information indicating a set of parameters the apparatus is allowed to indicate in the UE assistance information message, the set of parameters including at least one of an operation complexity control parameter, a network coverage control parameter, or a channel monitoring control parameter. The apparatus transmits the UE assistance information message, wherein the UE assistance information message is based on at least a portion of the set of parameters.

Abstract: Methods, systems, and devices for wireless communications are described. Techniques described herein relate to a user equipment (UE) that may include a wakeup radio in addition to a main radio to monitor for wakeup signals while the UE is in a sleep mode. The wakeup radio receiver may use less power than the main radio. In some examples, a first UE may indicate to a wireless node (e.g., a controlling sidelink UE or a network entity) that the UE is capable of sending wakeup signals to a second UE. In such examples, the wireless node may transmit a wakeup signal intended for the second UE to the first UE based on the capability report. The first UE may relay the wakeup signal to the second UE. Responsive to receiving the wakeup signal, the second UE may wake up the main radio of the second UE for communications.

Abstract: Techniques to enable and provide beam failure recovery (BFR) operation for discontinuous reception (DRX) modes with wakeup signal (WUS) monitoring are described. DRX mode operation may be altered based on a BFR procedure implemented by a user equipment (UE). DRX mode operation may be altered for allowing a UE to start a DRX active time after transmitting a BFR request signal of a BFR procedure. Additionally or alternatively, DRX mode operation may be altered for allowing a UE to start an ON duration timer for a next DRX cycle after transmitting a BFR request signal of a BFR procedure. In another example, DRX mode operation may be altered for allowing a UE to monitor a BFR search space set regardless of DRX status, after transmitting a BFR request signal for a BFR procedure. Other aspects and features are also claimed and described.

Abstract: Methods, systems, and devices for wireless communications are described. A communication device, such as a user equipment (UE) may receive control signaling indicating a set of configurations including a set of random access channel (RACH) configurations or a set of scheduling request (SR) configurations. At least one RACH configuration of the set of RACH configurations includes a UE-group common RACH configuration or at least one SR configuration of the set of SR configurations includes a UE-group common SR configuration. The UE may select one or more configurations of the set of RACH configurations or the set of SR configurations based on receiving the control signaling and may perform the wireless communications.

Abstract: Certain aspects of the present disclosure provide techniques for paging early indication (PEI) configuration and monitoring procedures. In particular, the present disclosure provides techniques for configuring a user equipment (UE) for PEI monitoring. A method that may be performed by a network entity generally includes transmitting, to the UE, a configuration for paging early indication (PEI) occasions for the UE to monitor and transmitting, in at least one of the PEI occasions, a physical downlink control channel (PDCCH) with a PEI that indicates, for multiple paging occasions (POs), whether paging messages are scheduled for the UE in the multiple POs.

Abstract: This disclosure provides systems, methods, and apparatuses, including computer programs encoded on computer storage media, for wireless communication. In one aspect of the disclosure, a method of wireless communication includes determining, at a user equipment (UE), that a current data transmission to a network entity is complete. The method further includes transmitting, to the network entity and based on the determination, an indication to terminate a discontinuous reception (DRX) active time assigned to the UE. Other aspects and features are also claimed and described.

Abstract: Methods, systems, and devices for wireless communications are described. In some systems, a user equipment (UE) may perform a random access channel (RACH) procedure with a base station. The UE may receive a message configuring a RACH preamble occasion and an uplink data occasion. The message may be a radio resource control (RRC) message or a system information (SI) message. In some cases, the UE may determine if the RACH preamble occasion, the uplink data occasion, or both are restricted for cancellation based on the message. The UE may determine when to monitor a downlink control channel for dynamic scheduling based on determining which occasions are restricted for cancellation and may transmit a RACH message based on monitoring—or not monitoring—the downlink control channel for dynamic scheduling preempting a RACH occasion. In some other cases, a base station may schedule transmissions to not overlap with configured RACH occasions.
