Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Radio communication systems face inefficiencies in utilizing downlink resources, particularly in relay-based wireless communication systems, where existing methods do not effectively manage resource allocation and signal transmission between base stations and relays.
Innovation Solution
The proposed method involves a relay system that optimizes downlink resource allocation by using a combination of Type 0, Type 1, and Type 2 resource allocation schemes, along with specific techniques for mapping virtual resource blocks to physical resource blocks, and employing demodulation reference signals to enhance signal transmission efficiency.

1Productivity
If existing downlink resource allocation methods are used in relay-based wireless communication systems, then the system can maintain basic communication functionality, but the utilization of downlink resources is inefficient
Solution Approach 1:
The patent segments downlink resource allocation into multiple types (Type 0, Type 1, and Type 2) with different granularity levels. Type 0 allocates resources in resource block groups (RBGs), Type 1 allocates in individual resource blocks (RBs), and Type 2 uses continuous allocation. This segmentation allows the system to select the most appropriate allocation method based on channel conditions and traffic requirements, thereby improving downlink resource utilization efficiency while reducing waste.
2Productivity
If multiple resource allocation schemes are implemented to improve resource utilization, then downlink efficiency improves, but system complexity increases
Solution Approach 1:
The patent implements dynamic resource allocation by allowing the base station to flexibly switch between Type 0, Type 1, and Type 2 allocation schemes based on real-time channel conditions, traffic patterns, and relay requirements. The system dynamically selects the optimal allocation type for each downlink transmission, enabling adaptive resource management that improves transmission efficiency while maintaining manageable complexity through standardized allocation procedures.

AI summary
The present invention relates to A METHOD AND A DEVICE FOR RECEIVING A DOWNLINK SIGNAL IN A WIRELESS COMMUNICATION SYSTEM. More specifically, the method of the present invention comprises the following steps: receiving first control information for downlink scheduling in the first slot of a resource block pair, wherein the first control information includes allocation information on at least one resource unit; receiving a data in the second slot of the resource block pair, when the allocation information on the resource unit having the resource block pair with the first control information has a first value; and attempting to detect second control information for uplink scheduling in the second slot of the resource block pair, when the allocation information on the resource unit having the resource block pair with the first control information has a second value.
