Resource Indication Channel for Flexible Wireless Allocation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Next-generation wireless communication systems, such as 5G, require flexible resource allocation and indication to manage large-range changes in bandwidth, delay, mobility, coverage, communication rate, reliability, and user number, which existing systems with fixed communication parameters cannot efficiently support.
Innovation Solution
A resource indication method where a base station generates and sends a resource indication channel to a terminal, configured to indicate time-frequency resources and communication parameters, allowing for improved flexibility in resource allocation and indication, using techniques like multi-antenna transmit diversity and single-carrier transmission to reduce detection complexity and enhance system efficiency.

Engineering Contradiction Analysis
1Adaptability or versatility
If fixed communication parameters are used in existing wireless communication systems, then system complexity is reduced and ease of operation is improved, but adaptability to diverse application requirements deteriorates
Solution Approach 1:
The patent implements dynamic resource indication by allowing the resource indication channel to flexibly indicate different time-frequency resources and communication parameters based on actual system conditions. The resource indication channel can adaptively select from multiple resource configurations, enabling the system to dynamically adjust to varying application requirements such as different bandwidths, delay constraints, mobility patterns, and reliability needs without requiring complex reconfiguration of the entire system architecture.
2Adaptability or versatility
If resource allocation flexibility is improved to support next-generation requirements, then adaptability is enhanced, but terminal detection complexity increases
Solution Approach 1:
The patent manages parameter complexity by changing the representation method of resource allocation information. Instead of terminals detecting and processing multiple independent parameter sets, the base station uses a compact resource indication channel that encodes resource allocation information in a streamlined format. The resource indication channel conveys essential resource information through efficient encoding schemes, allowing terminals to decode resource allocations with reduced detection complexity while still supporting flexible resource allocation for diverse application scenarios.

AI summary
A resource indication method, a base station and a terminal are provided. The method includes that: the base station generates a resource indication channel, the resource indication channel indicating a first time-frequency resource and a communication parameters for using the first time-frequency resource, the resource indication channel occupying a second time-frequency resource and at least one first time-frequency resource corresponding to at least one resource indication channel forming a cell; and the base station sends the resource indication channel to the terminal. The method can improve resource allocation and indication flexibility, and improve performance and applicability of a wireless communication system.
