Terminal Activation Signal Resource Allocation Flexibility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In the context of New Radio (NR) and LTE-IoT, there is a need for a flexible arrangement of resources for transmitting and receiving wake-up signals (WUS) between base stations and terminals, particularly to allow coexistence of Rel-15 and Rel-16 WUS in the same resource.
Innovation Solution
A terminal is equipped with a receiver to obtain configuration information for first and second activation signals associated with paging occasions, a controller to determine the time/frequency domain positions of resources allocated for these signals, and a communication unit to receive the signals and associated paging from the base station. The controller associates the positions of the first and second activation signals to allocate resources flexibly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed arrangement for WUS resources is used according to related art, then the system is simple to implement, but the system lacks flexibility in arranging activation signals and cannot support coexistence of multiple release versions
Solution Approach 1:
The patent implements dynamic resource allocation for WUS by allowing the network to flexibly configure time and frequency resources for activation signals through higher-layer signaling. The terminal adapts to different resource arrangements based on received configuration information, enabling the system to dynamically adjust resource allocation according to traffic conditions and coexistence requirements between different release versions.
Solution Approach 2:
The patent creates a universal resource allocation mechanism that can handle multiple scenarios: standalone Rel-15 WUS, standalone Rel-16 WUS, and coexistence of both types. The configuration information structure and resource determination method are designed to be universally applicable across different deployment scenarios, allowing the same framework to support various activation signal arrangements without requiring separate mechanisms for each case.
2Productivity
If separate resources are allocated for Rel-15 WUS and Rel-16 WUS, then coexistence is ensured, but resource utilization efficiency decreases
Solution Approach 1:
The patent merges the resource allocation mechanisms for Rel-15 WUS and Rel-16 WUS into a unified framework. By using a common configuration information structure and resource determination method, the system can allocate resources for both types of activation signals simultaneously. The network can configure resources such that both Rel-15 and Rel-16 terminals can correctly identify and receive their respective activation signals, achieving coexistence while improving resource utilization through shared resource pools.
3Adaptability or versatility
If flexible resource arrangement is implemented, then adaptability improves, but the complexity of determining resource positions increases
Solution Approach 1:
The patent implements feedback mechanisms where the network provides configuration information to terminals through higher-layer signaling, and terminals use this information to determine resource positions. The configuration information includes parameters that directly indicate or enable calculation of time and frequency resource positions for activation signals. This feedback loop allows terminals to accurately identify resource positions without complex blind searches, reducing detection difficulty while maintaining flexible resource arrangement capabilities.

AI summary
A terminal includes a receiver that receives, from a base station, configuration information for at least one of a first activation signal or a second activation signal associated with a paging occasion; a controller that determines, based on the configuration information, a time/frequency domain position of resources on which the first activation signal or the second activation signal is allocated; and a communication unit that receives the first activation signal or the second activation signal on the resources and receives, from the base station, paging associated with the received first activation signal or second activation signal, wherein the controller determines the time/frequency domain position of the resources on which the first activation signal and the second activation signal is allocated, by associating the positions of the resources.
