Description

METHODS AND SYSTEMS FOR ENERGY SAVING COORDINATION IN A WIRELESS NETWORK

[0001] Embodiments disclosed herein relate to wireless communication networks, and more particularly to enhanced methods and systems for Energy Saving (ES) coordination for User Equipments (UEs) and Network entities.

[0002] Wireless communication network traffic is exponentially increasing, and this is accompanied with increasing energy consumption and costs. The Radio Access Network (RAN) portion of the network traffic contributes up to 73% of overall energy consumption for the networks. At the same time, devices suffer severely due to limited battery life.

[0003] It can be noted that 5G has mainly focused on the reduction of transmission and reception to achieve enhanced energy saving; however, it is invariably accompanied with poor performance and / or limitation of the supported features. Moreover, energy saving on the User Equipment (UE) side, and the network (NW) sides in 5G are not targeted and not designed to work in a synchronized manner; potentially resulting in counteractive approaches when put together. As 6G includes new services and performance requirements, it is important to target substantial energy saving over that was achieved for 5G.

[0004] Hence, there is a need in the art for solutions which will overcome the above mentioned drawback(s), among others.

[0005] The principal object of embodiments herein is to disclose methods and systems for energy saving coordination for UEs and Network entities in a wireless communication network.

The network entity 102 can serve one or more cells.

[0038] FIG. 2 depicts a UE in a 6G network. The UE 101 comprises a processing module 101A, a transceiver module 101B, and a memory module 101C. The processing module 101A may include one or a plurality of processors. The one or the plurality of processors may be a general-purpose processor, such as a central processing unit (CPU), an application processor (AP), or the like, a graphics-only processing unit such as a graphics processing unit (GPU), a visual processing unit (VPU), and / or an AI-dedicated processor such as a neural processing unit (NPU).

The configuration parameters can be related to UE C-DRX, Cell-DRX / Cell-DTX, energy saving modes, on-demand SSB, on-demand SIB1 and wake-up signal or wake-up radio, and can indicate one or more configuration parameters and comprise steps for setup or release or modification of the same. UAI signaling can refer to, such as, but not limited to, RRC message UEAssistanceInformation in New Radio (NR or 5G) Radio Resource Control (RRC), or any other message which provides similar signaling in 6G or other technologies.

[0215] FIG. 12 depicts a process of the network entity managing energy saving in a network. Consider that the network entity 102 has provided the configuration for UAI signaling for energy saving to the UE through an OtherConfig information element in the RRC reconfiguration message. The configuration for an UAI signaling for energy saving comprises one or more preferred configurations for at least one of the UE C-DRX, the Cell-DRX / Cell-DTX, the energy saving mode, the OD-SSB, the on-demand SIB1, and the wake-up signal / radio in a RRC reconfiguration message.

In step 1201, the network entity 102 receives at least one energy saving preference from the UE, wherein the energy saving preference is based on the UAI signaling for energy saving by the UE. In step 1202, the network entity 102 determines a new configuration or reconfiguration for the UE, based on at least one energy saving preference received from the UE. In step 1203, the network entity 102 sends the determined new configuration or reconfiguration to the UE.

[0216] FIG. 13 is a flowchart depicting the process of managing energy saving in a network. In step 1301, a check is made if the UE 101 is configured for UAI signaling for indicating or requesting a preference of energy saving. If the UE 101 is configured for UAI signaling for indicating or requesting a preference of energy saving, in step 1302, the UE 101 determines if at least one triggering condition for one or more preferences for energy saving have been fulfilled. If at least one triggering condition for one or more preferences for energy saving have been fulfilled, in step 1303, the UE 101 checks whether the UE 101 has a preference on a configuration parameter of a call or cell group for energy saving and the UE 101 did not transmit aUEAssistanceInformationmessage with preferences for the cell or cell group since it was configured to provide its preference on configuration parameter of a cell or cell group for energy saving; or whether the current preference on a configuration parameter for the cell or cell group is different from the one indicated in the last transmission of theUEAssistanceInformationmessage including preference on a configuration parameter for the cell or cell group for energy saving and associated timer Txyz for the cell or cell group is running. If yes, in step 1304, the UE 101 starts the timer Txyz with the timer value set to the PreferenceProhibitTimer of preference on a configuration parameter of the cell or cell group for energy saving. In step 1305, the UE 101 initiates transmission of theUEAssistanceInformation messageto provide the current preference on a configuration parameter of the cell or cell group. The various actions in method 1300 may be performed in the order presented, in a different order or simultaneously. Further, in some embodiments, some actions listed in FIG. 13 may be omitted.

andmemory storing instructions,wherein the instructions, when executed by the at least one processor, cause the at least one processor to:provide a configuration for a user equipment (UE) assistance information (UAI) signaling for energy saving to at least one UE through an OtherConfig information element in a radio resource control (RRC) reconfiguration message, wherein the configuration for an UAI signaling for energy saving comprises:one or more preferred configurations for at least one of the UE connected-mode discontinuous reception (C-DRX) configuration, the Cell-DRX / Cell- discontinuous transmission (DTX), an energy saving mode, on-demand synchronization signal block (SSB) (OD-SSB), on-demand system Information block index one (SIB1), and the wake-up signal or wake-up radio in a RRC reconfiguration message, wherein the one or more preferred configurations comprise of setup or release or modification; and at least one parameter for the configuration;receive, through the at least one transceiver, at least one energy saving preference from the UE, wherein the energy saving preference is based on the UAI signaling for energy saving by the UE;determine a new configuration or reconfiguration for the UE, based on at least one energy saving preference received from the UE; andsend, through the at least one transceiver, the determined new configuration or reconfiguration to the UE.
