Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may support various extended reality (XR) applications. In some examples of XR applications, features from the real and virtual environments may be overlaid and displayed to a user for consumption via the UE. To avoid visual conflicts, such as misaligning objects from the real and virtual environments, and other visual conflicts, the UE may generate and send pose information to a network (e.g., a server hosting the XR application). The UE may be configured to manage transmission of pose information to the network, which may result in reduced power consumption. For example, the UE may determine a downlink burst occasion for the XR application, generate pose information associated with the UE and the XR application, and transmit the pose information only during the downlink burst occasion.

Abstract: Wake-up signal (WUS) downlink control information (DCI) may be configured to convey a wake-up indication as well as UE wake-up behavior configuration information. For example, WUS DCI may include one or more wake-up indications for one or more UEs via wake-up indication bits (e.g., wake-up indication bits may be conveyed in locations of the WUS DCI associated with monitoring indices of the one or more UEs to be activated). For example, WUS DCI may be encoded to include a wake-up indication and an indication of behavior configuration information for a group of one or more UEs. UE wake-up behavior configuration information may indicate some BWP to activate, may trigger a CSI report, etc. A UE may decode the wake-up indication and the wake-up behavior configuration information based on a monitoring index and the WUS configuration.

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 techniques for wake-up resource randomization for discontinuous reception operation. An example method generally includes obtaining configuration information for receiving at least one wake up signal (WUS) during an OFF duration of a discontinuous reception (DRX) mode of the UE; monitoring, during a WUS monitoring occasion occurring during the OFF duration of the DRX mode, the one or more resources for the at least one WUS based on the configuration information; and transitioning to an ON state of the DRX mode when the at least one WUS is detected in the one or more resources during the monitoring; or remaining in an OFF state of the DRX mode when the at least one WUS is not detected in the one or more resources during the monitoring.

Abstract: A UE may enter a dormant state, e.g., for power savings. The systems, methods, and apparatus described herein may provide ways for the UE to transition between an active state and a dormant state, as well as UE behavior in a dormant state. The apparatus may be a UE configured to receive an indication of a bandwidth part (BWP) switch for a secondary cell and to transition between an active state and a dormant state for the secondary cell based on the indication of the BWP switch.

Abstract: Certain aspects of the present disclosure provide techniques for channel state information measurement adaptation to maximum multiple-input multiple-output layers. A method that may be performed by a user equipment (UE) includes receiving a first channel state information (CSI) report configuration including one or more first CSI reference signal (CSI-RS) resources, wherein each first CSI-RS resource comprises a first resource set; determining, based on an indication of a maximum number of multiple-input multiple-output (MIMO) layers that the UE is expected to receive, a first resource subset on which to report first CSI; and reporting the first CSI to a base station (BS), wherein the first CSI is based on the determined first resource subset.

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: Techniques and apparatus for a control plane design for bandwidth part (BWP) in new radio (NR) are provided. One technique includes sending information with an indication of a BWP capability of a user equipment (UE) to a base station (BS). A configuration from the BS indicating a set of BWPs available to use for communication is received in response to the indication. Communications are performed on at least one of the set of BWPs. Another technique includes receiving information having an indication of a BWP capability of the UE. A configuration indicating a set of BWPs available for the UE to use for communication is determined. The configuration is sent to the UE.

Abstract: Aspects of the present disclosure provide a time division duplex (TDD) subframe structure that supports both single and multiple interlace modes of operation. In a single interlace mode, control information, data information corresponding to the control information and acknowledgement information corresponding to the data information are included in a single subframe. In a multiple interlace mode, at least one of the control information, the data information corresponding to the control information or the acknowledgement information corresponding to the data information is included in a different subframe. Both single and multiple interlace modes can be multiplexed together within the TDD subframe structure.

Abstract: Certain aspects of the present disclosure provide techniques for adapting cross-slot scheduling based on carrier groups. For example, certain aspects provide techniques for receiving a time-domain configuration comprising one or more offset values of time-domain resources relative to reception of physical downlink control channel (PDCCH), determining which at least one offset value of the one or more offset values are greater than or equal to a minimum offset value of the corresponding carrier, and for each carrier of the group of carriers, one or more of transmitting over a physical uplink shared channel (PUSCH) or monitoring a physical downlink shared channel (PDSCH).
