Abstract: Wireless communications systems and methods related to network power saving are provided. In one embodiment, a base station (BS) of a wireless communication network determines to enter a sleep mode. The BS transmits, to one or more user equipment (UEs) of the wireless communication network, a communication signal indicating that the BS will enter the sleep mode. The BS operates in the sleep mode for a sleep mode period. In one embodiment, a UE receives, from a BS, a communication signal indicating that the BS will enter a sleep mode for a sleep mode period. The UE refrains, during one or more sleep windows of the sleep mode period, from performing uplink communications.

Abstract: Methods, systems, and devices for wireless communications are described. In one example, a method includes receiving signaling from a base station to activate a semi-persistent scheduling (SPS) configuration for transmission between the base station and the UE, and receiving a hybrid automatic repeat request (HARM) timing for downlink transmissions based at least in part on the SPS configuration being activated. In another example, the method includes establishing a connection with a base station using a component carrier (CC), the CC having a plurality of bandwidth parts (BWPs), receiving signaling that indicates an SPS configuration or other types of pre-configured resources associated with at least a first BWP of the plurality of BWPs and transmitting or receiving using at least the first BWP according to the SPS configuration or other types of pre-configured resources associated with at least the first BWP.

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 downlink control information (DCI) comprising an indication of a bandwidth part (BWP) switch for a secondary cell to a dormant BWP and transition the secondary cell from an active state to a dormant state based on the indication of the BWP switch of the secondary cell to a dormant BWP.

Abstract: Certain aspects of the present disclosure provide techniques for PEI location determination. According to certain aspects, a method of wireless communication by a user equipment (UE) includes receiving, from a network entity, a configuration of a paging early indication (PEI) that indicates, for multiple paging occasions (POs) in multiple paging frames (PFs), whether paging physical downlink control channels (PDCCHs) are scheduled in the multiple POs, identifying a reference PF from one of the multiple PFs, and monitoring for the PEI in a location of a PEI occasion determined based on the reference PF and at least one timing offset.

Abstract: Methods, systems, and devices for wireless communications are described. A base station may implement cross-carrier scheduling. A user equipment (UE) may identify a minimum scheduling delay and may receive a downlink grant on a first CC. The UE may further identify the slot in which a downlink data transmission corresponding to the downlink grant will be received, and may identify the slot such that the minimum scheduling delay is satisfied. The UE may the receive the downlink data transmission, as indicated in the downlink grant, in the identified slot. In some examples, the UE and the base station may alternate between a long minimum scheduling delay and a short minimum scheduling delay. In some examples, the UE and the base station may alternate between a cross-carrier mode, and a self-scheduling mode.

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: Methods, systems, and devices for wireless communication are described related to a duty cycle configuration for power saving. A user equipment (UE) may receive control signaling indicating a duty cycle for cycling between a first power state associated with a first configuration and a second power state associated with a second configuration. In some examples, the first and second configurations may indicate a bandwidth part (BWP) configuration, restricted reception or transmission of one or more channels within the BWP configuration, or both for the UE. The UE may communicate first data traffic in accordance with the first configuration while operating in the first power state. The UE may transition from the first power state to the second power state in accordance with the duty cycle. The UE may communicate second data traffic in accordance with the second configuration while operating in the second power state.
