Priority Beam Paging for Wireless Network Power Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The increasing number of beams in communication networks, particularly in densely populated areas, leads to significant signaling overhead and power consumption due to the need for communication devices to scan multiple beams for paging messages, even if no actual message is intended for them, resulting in rapid battery depletion and increased time spent on scanning operations.
Innovation Solution
Identifying a priority set of beams that provides sufficient coverage while reducing the number of beams used for paging, allowing devices to check only the most relevant beams for messages, thereby minimizing signaling overhead and power consumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple beams are used to cover an entire cell in densely populated areas, then signal coverage and capacity are improved, but signaling overhead and power consumption increase significantly
Solution Approach 1:
The patent segments the set of beams into a first set of beams and a second set of beams. The first set of beams is used for transmitting paging messages, while the second set of beams is used for other communication functions. This segmentation allows the system to maintain comprehensive coverage through multiple beams while reducing the number of beams actively used for paging, thereby lowering power consumption and signaling overhead.
2Reliability
If communication devices scan all beams for paging messages, then no paging message is missed, but time spent on scanning operations increases
Solution Approach 1:
The patent extracts the paging message transmission function from all beams and concentrates it into a specific first set of beams. By taking out the paging function from the full beam set and isolating it in a subset, the communication device only needs to scan the first set of beams for paging messages, significantly reducing scanning time while ensuring no paging message is missed.
3Power
If beamforming is used to focus signal energy, then signal-to-noise ratio and throughput are enhanced, but the number of required beams to cover the same area increases
Solution Approach 1:
The patent applies local quality by differentiating the roles of different beam sets. The first set of beams is specifically optimized for paging message transmission with focused signal energy, while the second set of beams handles other communication functions. This local differentiation allows the system to maintain high signal-to-noise ratio where needed while managing the overall number of beams through functional specialization.

AI summary
Aspects of this disclosure may include identifying a priority set of beams from a set of beams associated with an area, wherein a first count of beams included in the priority set of beams is less than a second count of beams included in the set of beams, transmitting, based on the identifying, at least one message that includes an identifier of each beam included in the priority set of beams, subsequent to the transmitting of the at least one message, transmitting a first paging message directed to a communication device in association with a first beam included in the priority set of beams, obtaining a first paging response from the communication device based on the transmitting of the first paging message, and transmitting first payload data associated with a communication service to the communication device based on the obtaining of the first paging response. Other embodiments are disclosed.
