Partial Cell Resource Activation for Selective SSB Beam Power Saving
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing power-saving mechanisms in radio communication networks waste power by activating entire cells when only partial resources are needed, leading to inefficient resource utilization and increased consumption.
Innovation Solution
A method for activating partial resources of a cell by transmitting a request message to a neighboring base station to determine and activate specific synchronization signal and physical broadcast channel (SSB) beams and bandwidth based on measurement results and configuration information, allowing for more precise resource management.

Engineering Contradiction Analysis
1Quantity of substance
If the entire cell is activated to serve terminals with heavy service volume, then the service capacity is sufficient, but the power consumption increases and resource utilization decreases
Solution Approach 1:
The patent segments the cell resources into multiple SSB beams, allowing selective activation of individual beams based on terminal distribution and service requirements. Instead of activating the entire cell, only the necessary SSB beams are activated to serve the terminals, thereby reducing power consumption while maintaining sufficient service capacity.
Solution Approach 2:
The patent applies local quality by activating SSB beams in specific local areas where terminals are located, rather than uniformly activating the entire cell. The base station determines which SSB beams to activate based on terminal measurement results and locations, ensuring that resources are concentrated where needed while other areas remain in low-power state.
2Use of energy by moving object
If only partial SSB beams are activated to reduce power consumption, then power efficiency improves, but the ability to serve all terminals may be compromised
Solution Approach 1:
The patent implements feedback mechanisms where terminals report measurement results of SSB beams to the base station. The base station uses this feedback information to intelligently determine which SSB beams should be activated to ensure all terminals can be served. This feedback loop maintains service reliability while enabling selective beam activation for power efficiency.
Solution Approach 2:
The patent makes the SSB beam activation dynamic rather than static. The base station can adjust which SSB beams are activated based on changing terminal distributions and service requirements. This dynamic adjustment ensures that the system maintains adequate service coverage while optimizing power consumption according to actual network conditions.

AI summary
Embodiments of the present invention provide a method and device for activating partial resources of a cell. The method is applied to a first base station and comprises: sending a first request message to a second base station to which a target cell belongs, the first request message being used for the second base station to determine an SSB beam needing to be activated in the target cell and/or a bandwidth needing to be activated. By means of the method for activating partial resources of the cell provided in the embodiments of the present invention, information related to measuring and reporting the SSB beam by a terminal is obtained by means of the first base station; when it is determined that the load of the first base station is relatively heavy, a neighboring base station is requested to activate one or more SSB beams in the target cell belonging to said base station and/or is requested to activate part of the bandwidth under said base station, and the neighboring base station avoids activation of the entire target cell on the basis of the request, thereby reducing energy consumption.
