Communication system, base station and mobile terminal

A mobile communication system capable of reducing energy consumption of a network node in a local area range. When judging that there is a shift trigger, a local eNB shifts from a normal operation to an energy saving operation. In the energy saving operation, the local eNB stops the operation of transmitting at least a part of downlink transmission signals to be transmitted to a user equipment (UE) and performs the operation of receiving an uplink transmission signal transmitted from the UE. When judging that it has received the uplink transmission signal (RACH) in the energy saving operation, the local eNB shifts to the normal operation.

Techniques for transmitting remaining minimum system information

Methods, systems, and devices for wireless communications are described. A base station may determine to operate in accordance with an energy saving mode in which the base station only transmits remaining minimum system information (RMSI) on-demand or reduces transmission of RMSI with respect to when the base station is operating outside of the energy saving mode. A user equipment (UE) may detect the base station that is operating in an energy saving mode. The UE may transmit a request for the base station to transmit the RMSI to the UE, where the UE may transmit the request to the energy saving base station or to a serving base station of the UE. The UE may receive, from the base station operating in the energy saving mode and responsive to the request, a message including the remaining minimum system information.

TECHNIQUES FOR WIRELESS COMMUNICATION IN CONNECTED DISCONTINUOUS RECEPTION MODE

Methods, systems, and devices for wireless communication are described. A user equipment (UE) may receive, from a base station, control signaling indicating a set of connected discontinuous reception (C-DRX) configurations. The set of C-DRX configurations may include a first C-DRX configuration and a second C-DRX configuration, where at least one C-DRX configuration in the set of C-DRX configurations is a UE-group common C-DRX configuration. The set of C-DRX configurations may correspond to a discontinuous transmission (DTX) cycle of the base station. The UE may select a C-DRX configuration from the set of C-DRX configurations based on receiving the control signaling from the base station. Accordingly, the UE may use the selected C-DRX configuration to communicate with the base station. The selected C-DRX configuration may enable the base station to operate with reduced power consumption and higher DTX efficiency, among other benefits.

20230007580 · 2023-01-05 ·

Systems and methods allow access stations to save power when no user equipment (UE) devices require service from the access station. The access station may enter a low power-consumption mode (or “sleep mode”) when the access station is inactive. The access station transmits a beacon signal when in the low power-consumption mode to indicate to UE devices in a coverage area of the access station that the access station is in the low power-consumption mode. The access station receives a wake-up signal from a device and, in response, exits the low power-consumption mode.

Managing power consumption of a network

Examples provided herein describe a method for managing power consumption of a network. For example, a network device may monitor a set of network area zones of a network coverage area, where each network area zone is associated with a set of edge devices. A first occupancy state may be determined for a first network area zone of the set of network area zones based on usage of a first set of edge devices of the first network area zone. Based on the determined first occupancy state, a first power consumption policy for the first network area zone may be determined. Responsive to determining the first power consumption policy, the determined first power consumption policy may be applied to the first set of edge devices in the first network area zone at least edge changing a power consumption mode of a first edge device in the first set of edge devices.

Wake-up signal management

The invention relates to a method for a wireless communication apparatus, and such an apparatus, configured to use a wake-up signal (WUS), transmitted for waking up a main receiver of a wireless communication device responsive to detection of the WUS by a wake-up receiver (WUR) of the wireless communication device. The method comprises controlling a bandwidth associated with the WUS based on a reception condition metric for the WUR. Embodiments may comprise determining the reception condition metric for the WUR by correlating a received signal comprising the WUS with a WUS reference signal to provide an extreme correlation value, and determining the reception condition metric for the WUR based on the extreme correlation value.

An intent state management method, network element, and system are described. A first network element obtains a first network parameter value corresponding to an intent; and determines, based on the first network parameter value corresponding to the intent, that a condition for achieving the intent is not satisfied. In accordance with the determination, the first network element suspends execution of the intent, sends a first notification message to a second network element, where the first notification message notifies the intent to enter a sleep state; and sets the sleep state to an active state when the condition for achieving the intent is satisfied or the intent is modified. Network resources of the first network element can be saved. When the condition for achieving the intent is satisfied or the intent is modified, the intent enters the active state, so that a state of the intent can be adjusted in time.
