Paging Bandwidth Synchronization for 5G UE Reception
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In the 5G NR system, User Equipment (UE) faces challenges in accurately receiving paging messages due to increased path loss and limited bandwidth capabilities, which affects the success rate of message reception during multi-beam scanning.
Innovation Solution
The method involves acquiring association relationships between paging bandwidths and synchronization or reference signals, allowing the UE to determine and receive a paging message in the corresponding bandwidth using these signals, thereby improving message reception accuracy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If the network system uses a wideband carrier with multi-beam scanning, then the coverage area is improved, but the path loss increases and message reception accuracy deteriorates
Solution Approach 1:
The patent segments the wideband carrier into multiple Bandwidth Parts (BWPs), each associated with specific synchronization signals and reference signals. This allows the UE to receive paging messages in a dedicated bandwidth portion with appropriate signal quality, rather than attempting to receive across the entire wideband carrier where path loss is higher.
Solution Approach 2:
The patent establishes association relationships between specific paging bandwidths and synchronization/reference signals, enabling the UE to use locally optimized signal quality from reference signals to compensate for path loss in specific bandwidth regions. This local quality enhancement improves message reception accuracy in each BWP.
2Adaptability or versatility
If the UE supports a maximum bandwidth less than the network system bandwidth, then the UE capability limitation is respected, but the paging message reception reliability deteriorates
Solution Approach 1:
The network segments the system bandwidth into multiple BWPs, and the UE is configured with specific BWPs according to its capability. The association relationship between paging bandwidths and reference signals ensures that the UE can reliably receive paging messages within its supported bandwidth, even though the total system bandwidth is larger.
Solution Approach 2:
The patent changes the bandwidth parameter from a single wideband carrier to multiple configurable BWPs. The UE can be dynamically assigned different BWP configurations based on its capability, and the association relationships ensure reliable reception within the assigned bandwidth parameters.
3Area of stationary object
If multi-beam scanning is used to cover the whole cell, then the coverage is improved, but the complexity of determining the correct beam for paging message reception increases
Solution Approach 1:
The patent establishes association relationships between paging bandwidths and synchronization/reference signals in advance, before the actual paging message transmission. This preliminary configuration allows the UE to quickly determine which beam to use for receiving paging messages without having to perform complex beam searching at the time of reception.
Solution Approach 2:
The patent uses synchronization signals and reference signals as intermediaries to link paging bandwidths with specific beams. The UE can use these intermediary signals to identify the correct beam for paging message reception, simplifying the beam determination process compared to direct beam searching.
