Shared Signaling Channel Resource Allocation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Wireless communication systems face challenges in efficiently allocating resources for shared signaling channels, leading to degradation of communication links and increased overhead, which affects system performance.
Innovation Solution
A shared signaling channel is implemented in a wireless communication system, where a predetermined number of sub-carriers are assigned to the channel, with power allocation varying based on communication link requirements, and messages are directed to specific access terminals, minimizing interference and overhead.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If dedicated communication channels are allocated for resource allocation transmission, then resource allocation communication reliability is improved, but system capacity and available resources for data transmission deteriorate
Solution Approach 1:
The patent applies universality by allowing communication channels to serve dual purposes: carrying both resource allocation signaling and data transmission. The base station dynamically multiplexes control information and user data over the same physical channels, eliminating the need for separate dedicated control channels while maintaining allocation reliability through intelligent resource management and signaling design.
2Reliability
If robust resource allocation channels are configured, then resource allocation reliability is improved, but system performance and communication efficiency deteriorate
Solution Approach 1:
The patent implements dynamics by making the resource allocation channel configuration adaptive rather than static. The base station dynamically adjusts the amount of resources allocated to control channels based on real-time system conditions, traffic load, and channel quality, ensuring reliable resource allocation communication while optimizing system performance through flexible resource management.
Solution Approach 2:
The patent applies parameter changes by varying the allocation of time-frequency resources, power, and coding rates for control channels based on system conditions. The base station modifies these parameters dynamically to maintain reliable resource allocation signaling while minimizing the impact on overall system capacity and communication efficiency.
3Stability of the object's composition
If fixed bandwidth is allocated to signaling channel, then channel stability is improved, but system flexibility and resource utilization deteriorate
Solution Approach 1:
The patent implements dynamics by transitioning from fixed to dynamic bandwidth allocation for signaling channels. The base station determines the required signaling channel bandwidth based on the number of active users, traffic patterns, and channel conditions, allocating resources adaptively to maintain channel stability when needed while maximizing system flexibility and resource utilization under varying conditions.

AI summary
A shared signaling channel can be used in an Orthogonal Frequency Division Multiple Access (OFDMA) communication system to provide signaling, acknowledgement, and power control messages to access terminals within the system. The shared signaling channel may comprise reserved logical resources that can be assigned to subcarriers, OFDM symbols, or combinations thereof.
