Abstract: Systems and methods for discontinuous reception (DRX) adaptation in a wireless communication system are provided. A network entity may configure a user equipment (UE) with a long DRX cycle. Under certain conditions, additional short DRX cycles may be activated by the network entity so that data may be transferred before the next DRX active time. Multiple aspects are described wherein short DRX cycle parameters are communicated explicitly or implicitly to the UE. Short DRX cycle parameters may be included and/or indicated by bits in a downlink control information (DCI) or a Medium Access Control (MAC) Control Element (CE) command received by the UE during the long DRX active time.

Abstract: A configuration that enables a UE to process a PDSCH DMRS bundle having a higher density of DMRS symbols at a beginning of the PDSCH DMRS bundle. The apparatus receives a PDSCH and DMRS in each slot of a plurality of slots, the DMRS being bundled across the plurality of slots, a first subset of slots of the plurality of slots each having a higher DMRS symbol density of DMRS than a second subset of slots of the plurality of slots, the second subset of slots being subsequent to the first subset of slots. The apparatus decodes each received PDSCH based on at least a subset of the received DMRS.

Abstract: Aspects are provided that allow a user equipment (UE) to facilitate a joint operation of search space set group switching and bandwidth part switching. The UE may switch from a first bandwidth part (BWP) to a second BWP. The UE also may monitor a first search space set group (SSSG) in the second BWP during a scheduled monitoring occasion based on a downlink monitoring configuration.

Abstract: A user equipment (UE) receives, from a base station, a network power mode configuration and receive control signaling indicating for the UE to switch to the network power mode configuration. The UE communicates with the base station based on the network power mode configuration in response to the control signaling. A base station transmits, to a UE, a network power mode configuration, and transmits control signaling indicating for the UE to switch to the network power mode configuration. The base station communicates with the UE based on the network power mode configuration in response to the control signaling.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a first user equipment (UE) may configure a discontinuous reception (DRX) cycle of the first UE for a sidelink connection with a second UE. The UE may identify a mode that specifies whether the first UE is to receive a communication outside of an on duration of the DRX cycle if the on duration is extended due to receiving sidelink control information (SCI) reserving a resource outside of the on duration. The UE may communicate in accordance with the mode. Numerous other aspects are described.

Abstract: Disclosed are techniques for wireless communication. In an aspect, a user equipment (UE) determines (e.g., based on an indication from base station) one or more physical random access channel (PRACH) preamble transmission parameters associated with one or more PRACH coverage enhancement (CE) levels of a RACH procedure. The UE and the base station perform a RACH procedure in accordance with the one or more PRACH preamble transmission parameters.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from a base station, a configuration message that indicates a radio resource allocation and a transmission scheme for one or more first configured grant-small data transfer (CG-SDT) occasions and one or more second CG-SDT occasions. The one or more second CG-SDT occasions are at least partially nested, in time, frequency, or a combination thereof, within the one or more first CG-SDT occasions. The UE may therefore transmit, to the base station, an uplink communication within the one or more first CG-SDT occasions or the one or more second CG-SDT occasions, using the radio resource allocation and the transmission scheme. Numerous other aspects are provided.

Abstract: Certain aspects of the present disclosure provide techniques for scheduling and bandwidth part (BWP) adaptation for extended reality (XR). A method that may be performed by a user equipment (UE) includes obtaining an indication to change at least one of a minimum control-channel-to-data-channel delay or a bandwidth for receiving a first transmission on a BWP; changing the at least one of the minimum control-channel-to-data-channel delay to a new minimum control-channel-to-data-channel delay or the bandwidth on the BWP to a new bandwidth; and receiving the first transmission on the BWP using the at least one of the new minimum control-channel-to-data-channel delay or the new bandwidth of the BWP.

Abstract: Methods, systems, and devices for wireless communications are described. A UE may receive a first stage wakeup signal (WUS) indicating to monitor for a second stage WUS using a low power radio. For example, the first stage WUS may indicate whether to monitor one or more upcoming monitoring occasions for the second stage WUS using the low power radio. The UE may receive the second stage WUS based on receiving the indication included in the first stage WUS. The second stage WUS may indicate for the UE to activate a main radio to monitor for a control channel to receive data transmitted by the network entity. Based on receiving the second stage WUS, the UE may activate the main radio and receive data from the network entity.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from a base station, a first physical downlink shared channel (PDSCH) transmission transmitted using a first modulation and coding scheme (MCS). The UE may transmit, to the base station, feedback based at least in part on decoding the first PDSCH transmission, wherein the feedback includes an acknowledgement (ACK) or negative acknowledgement (NACK) and a channel state information (CSI) report that includes at least an indication of a second MCS based at least in part on a target block error rate (BLER) and a target charging rate for energy harvesting. Numerous other aspects are described.
