Slotted Radio Station Pause Reception for Multi-Slot Transmission
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In slotted radio data communication systems like GSM, the need to send control acknowledgments or reports during a single time slot limits the allocation of multiple successive time slots for data communication, restricting throughput capacity.
Innovation Solution
A method and apparatus that allow a communication station to pause data reception intermittently and switch operational modes to transmit control acknowledgments or other data, enabling multi-slot communication allocations, including entire frames, by autonomously selecting time slots for transmission and informing the network of its capabilities.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a communication station is allocated multiple successive time slots for data reception, then the data throughput capacity is improved, but the station cannot transmit control acknowledgments or reports in a timely manner
Solution Approach 1:
The communication station dynamically switches between reception mode and transmission mode on different time slots. The station can be allocated multiple time slots for data reception and still transmit control acknowledgments by utilizing other time slots in the frame, allowing flexible adaptation between receiving and transmitting functions to resolve the contradiction between high throughput and reliable control feedback
Solution Approach 2:
The time frame is segmented into multiple time slots with different functions. Some time slots are dedicated to data reception while other time slots are used for control acknowledgment transmission. This segmentation allows the system to maintain high data throughput during reception slots while ensuring reliable control feedback during transmission slots
2Reliability
If a time slot is reserved for control acknowledgments, then control feedback reliability is improved, but the allocation of multiple successive time slots for data communication is limited
Solution Approach 1:
The communication station is designed with multi-functionality, capable of performing both data reception and control acknowledgment transmission. By allocating different time slots for different functions within the same frame structure, the system ensures that control feedback reliability is maintained while maximizing data communication opportunities in other time slots
3Reliability
If the communication station transmits control acknowledgments intermittently, then control feedback is maintained, but reception operations are interrupted
Solution Approach 1:
The communication station employs periodic action by transmitting control acknowledgments at regular intervals using specific time slots allocated for this purpose. This periodic transmission ensures reliable control feedback while the station continues data reception in other time slots, minimizing overall reception interruption by utilizing the structured periodic nature of time-slotted frames
Data Source
AI summary
Apparatus, and an associated method, that facilitates communication of data in a radio communication system that utilizes a slotted communication scheme. Multiple successive time slots are allocable upon which to communicate data to a receiving communication station. At selected intervals, a controller causes the mode of operation of the receiving communication station to be changed to pause operation in a receive mode and, during the pause, to cause operation of the receiving communication station to transmit data, such as control acknowledgments or other responses.
