Wireless Transmission Slot Segmentation for Handoff Resource Optimization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In wireless communication systems, transmissions that overlap with scheduled transmission gaps often result in inefficiencies as entire transmission frames are cancelled, even if the overlap is minor, leading to unnecessary resource wastage.
Innovation Solution
A method is introduced to identify the actual transmission gap within a scheduled gap, allowing only information outside the actual gap to be transmitted, thereby preventing unnecessary cancellations and optimizing resource utilization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If entire transmission frames are cancelled when overlapping with scheduled transmission gaps, then transmission gap functionality is ensured, but resource utilization deteriorates due to unnecessary cancellations
Solution Approach 1:
The patent segments the transmission frame into multiple slots and identifies the actual transmission gap at the slot level rather than cancelling entire frames. This allows partial transmission of slots that do not overlap with the gap, resolving the contradiction by maintaining gap functionality while improving resource utilization through granular control.
Solution Approach 2:
The patent applies different transmission decisions to different parts of the transmission frame based on local overlap conditions with the transmission gap. Slots overlapping with the gap are cancelled while non-overlapping slots are transmitted, creating local quality differentiation that resolves the contradiction between gap reliability and overall resource utilization.
2Reliability
If entire transmission frames are cancelled when overlapping with scheduled transmission gaps, then transmission gap functionality is ensured, but transmission efficiency deteriorates due to unnecessary resource wastage
Solution Approach 1:
The patent divides the transmission frame into selectable slots and applies cancellation decisions at the slot level rather than frame level. This segmentation enables transmission of non-overlapping slots during compression periods, maintaining gap reliability while improving transmission efficiency by eliminating unnecessary cancellations.
Solution Approach 2:
The patent applies partial action by cancelling only the portion of transmission slots that actually overlap with the transmission gap rather than cancelling the entire frame. This partial cancellation approach maintains sufficient gap functionality while preserving transmission efficiency through selective slot transmission.
3Reliability
If scheduled transmission gaps are used for handoff monitoring, then mobile device connectivity is maintained, but resource wastage increases due to conservative transmission cancellation
Solution Approach 1:
The patent segments transmission resources into individual slots and uses the actual transmission gap to determine which specific slots to cancel. This enables mobile devices to maintain connectivity during handoff monitoring while reducing resource wastage by transmitting slots that fall outside the actual gap period.
Solution Approach 2:
The patent changes the parameter of transmission cancellation from frame-level to slot-level based on the actual transmission gap timing. This parameter change allows the system to maintain connectivity reliability while minimizing resource wastage through precise control of transmission cancellation boundaries.

AI summary
A method is provided for controlling communications between a base station and a mobile device. The method comprises determining the actual transmission gap and only discarding slots and / or frames that overlap with the actual transmission gap. Slots and/or frames that overlap with a scheduled transmission gap but are outside the actual transmission gap are transmitted.
