Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In MIMO communication systems with relays, the inclusion of a relay node increases the consumption of radio resources such as time sections, leading to reduced data rates due to the need for additional time slots for data transmission between the base station, relay, and mobile station.
Innovation Solution

Engineering Contradiction Analysis
1Area of stationary object
If a relay is included in the communication system to extend coverage, then the coverage area is improved, but the consumption of radio resources (time sections) increases and data rate decreases
Solution Approach 1:
The patent merges the transmission of base station data and mobile station data into a single relay data transmission process. The relay station combines both data streams and transmits them simultaneously to the base station and mobile station respectively, eliminating the need for separate time sections for each transmission direction.
Solution Approach 2:
The relay station acts as an intelligent intermediary that receives data from both the base station and mobile station, processes and combines them into relay data, and then transmits the combined data back to both parties. This mediator approach allows efficient resource utilization by coordinating transmissions through the relay.
2Area of stationary object
If a relay is included in the communication system to extend coverage, then the coverage area is improved, but the data rate is reduced due to additional time slots required
Solution Approach 1:
The patent enables continuous useful action by allowing the relay station to transmit combined data to both base station and mobile station in a single operation. This continuous transmission approach eliminates idle time sections and maintains productive data transmission throughout the communication process.
Solution Approach 2:
By merging multiple data transmission tasks into a single relay data transmission operation, the system achieves higher productivity. The relay combines base station data and mobile station data, then transmits the combined relay data to both destinations simultaneously, maximizing data rate efficiency.
3Reliability
If traditional relay transmission is used with separate time sections for base station to relay and relay to mobile station, then signal reliability is maintained, but radio resource efficiency deteriorates
Solution Approach 1:
The relay station serves as an intelligent intermediary that maintains signal reliability through proper data combination and transmission protocols while optimizing time section usage. The relay processes incoming data from base station and mobile station, combines them appropriately, and transmits the result back to both parties in an efficient manner.
Solution Approach 2:
The patent changes the transmission parameter structure by transmitting relay data that contains both base station data and mobile station data in a single time section. This parameter change from separate transmissions to combined transmission maintains reliability while reducing time section consumption.

AI summary
Disclosed is a data transmission system that transmits data using a relay. During a first time slot, a base station may transmit base station data to the relay, and a mobile station may transmit mobile station data to the relay. During a second time slot, the relay may transmit the mobile station data to the base station, and transmit the base station data to the mobile station.
