Paging Indicator Grouping for 5G UE Monitoring Efficiency
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In 5G New Radio systems, user equipment experiences high blind detection complexity and low paging monitoring efficiency during paging monitoring processes.
Innovation Solution
The method involves grouping user equipment into cells, allocating group identifiers, and transmitting paging indicators to the equipment, allowing them to monitor paging control information efficiently by utilizing specific time-frequency resources not occupied by synchronization signals, thereby reducing blind detection complexity.

If user equipment directly monitors paging control information on PDCCH, then paging monitoring function is achieved, but blind detection complexity increases and monitoring efficiency decreases
Solution Approach 1:
The patent introduces a paging indicator as an intermediary element between the paging control information and the user equipment. This indicator is transmitted on dedicated time-frequency resources and provides advance notification to user equipment about the presence of paging messages, thereby reducing the need for continuous blind detection on PDCCH and improving monitoring efficiency while lowering detection complexity
Solution Approach 2:
The patent implements preliminary action by transmitting paging indicators in advance before the actual paging control information. User equipment monitors these indicators first, and only when indicated present, does the equipment proceed to decode the corresponding paging messages. This preliminary notification mechanism reduces unnecessary blind detection operations and improves overall paging monitoring efficiency

AI summary
Method, device, base station and user equipment for implementing paging monitoring are described. At a base station side, the method includes: grouping a user equipment in a cell controlled by the base station, and allocating a group identifier to each group; for each user equipment, transmitting the group identifier corresponding to the user equipment and a paging indicator monitoring occasion to the user equipment; transmitting a paging indicator to the user equipment currently required to be paged or scheduled. At a user equipment side, the method includes: receiving a group identifier and a paging indicator monitoring occasion transmitted from a base station; monitoring a paging indicator at the paging indicator monitoring occasion; starting to monitor paging control information, when it is monitored that the paging indicator contains the group identifier.
