Methods, systems, and devices for wireless communications are described to enable a mobile access node to enter a new power state based on detection of a second access node. The second access node may be detected by the mobile access node or a central unit (CU). The mobile access node or the CU may determine for the mobile access node to enter a new power state and may notify the other of the determination. The mobile access node may enter a lower power state if the second access node is within a defined proximity or if one or more thresholds are exceeded. The mobile access node may enter a higher power state if no other access nodes are within the defined proximity or if the one or more thresholds are not exceeded. Configuration parameters for a power state change procedure may be configured by control signaling from a CU.

A communications device including a receiver configured to receive signals within sidelink communications resources of a plurality of resource pool instances of a sidelink interface, each of the resource pool instances being arranged in time in accordance with a resource pool periodicity, and a controller. The controller is configured in combination with the receiver to switch at a first periodic rate between a primary active operating mode and a primary reduced power operating mode in accordance with a primary discontinuous reception, DRX, operation, to monitor for signals transmitted by the other communications devices to the receiving communications device in one or more of the resource pool instances during the primary active operating mode, and to stop monitoring for signals transmitted by the other communications devices to the receiving communications device in one or more of the resource pool instances during the primary reduced power operating mode.

A wireless communication method for use in a wireless terminal is disclosed. The wireless communication method comprises determining an intermediate transport block size (TBS) for a transport block transmitted between the wireless terminal and a wireless network node based on a plurality of transmission parameters, modifying the intermediate TBS to generate a modified TBS in response to at least one event, and determining a final TBS based on the modified TBS and a specific step in response to the at least one event, wherein the specific step is determined based on the plurality of transmission parameters

Embodiments of this application provide a configuration information obtaining method and an apparatus, which may be applied to a scenario in which a terminal device obtains an RNTI. The terminal device may be in RRC inactive mode. The method may include: obtaining a cell identifier, and obtaining first configuration information based on the cell identifier, where there is a correspondence between the cell identifier and the first configuration information, and the first configuration information is used to configure an RNTI; and performing one or more of the following operations based on the first configuration information: receiving downlink control information, receiving downlink data, sending uplink control information, or sending uplink data.

A Medium Access Control (MAC) entity of a user equipment (UE) comprises a primary discontinuous reception (DRX) group and a secondary DRX group. A control channel is monitored for receiving downlink control information (DCI) in at least one serving cell in at least one of the primary DRX group or the secondary DRX group.

This disclosure describes systems, methods, and apparatus related to a restrictive target wake time (TWT) service period (SP) system. A device may determine a beacon frame to be sent to one or more power save devices. The device may determine a time duration of a TWT SP associated with the one or more power save devices. The device may determine a first trigger frame including a cascade indication. The device may determine a first time associated with the first trigger frame. The device may cause to send the trigger frame to the one or more power save devices based at least in part on a remaining duration of the TWT SP.

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may generate a wake up signal to wake up a plurality of second UEs. The wake up signal may be based at least in part on location information associated with the UE, location information associated with one or more of the plurality of second UEs, or a combination thereof. The UE may further transmit, to the plurality of second UEs, the wake up signal. Accordingly, the plurality of second UEs may receive the wake up signal and monitor for messages from the second UE based at least in part on receiving the wake up signal. Numerous other aspects are provided.

A first communication device determines whether a second communication device is in a power save mode with respect to a first communication link among a plurality of communication links that correspond to respective frequency segments, and determines whether the second communication device is in a power save mode with respect to a second communication link among the plurality of communication links. The second communication device is permitted to be in the power save mode with respect to the second communication link when the second communication device is not in the power save mode with respect to the first communication link, and vice versa. The first communication device communicates with the second communication device in accordance with the power save modes of the second communication device with respect to the first and second communication links.

A method for monitoring a communications channel between a terminal device and a network device is described. The method includes: obtaining a first search space configuration and a second search space configuration. The first search space configuration includes a first search space set and the second search space configuration includes a second search space set, or the first search space configuration includes a first search space parameter and the second search space configuration includes a second search space parameter. The method further includes monitoring a physical downlink control channel (PDCCH) based on the first search space configuration if a first condition is met. The first condition includes: a first timer is not in a running state; or monitoring, by the terminal device, a PDCCH based on the second search space configuration if a second condition is met. The second condition includes a first timer is in a running state.

Embodiments herein relate e.g. to a method performed by a UE (10) for managing monitoring of a control channel for transmissions from a radio network node (12). The UE activates, upon detection of a triggering event occurrence, a timer, wherein the triggering event occurrence comprises transmitting a scheduling request and/or receiving a RAR. The UE further initiates, upon expiry of the timer, a monitoring of a control channel for one or more transmissions from the radio network node.
