Multi-sector Rate Control for Wireless Scheduling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In wireless communication systems, existing technologies face inefficiencies in data transmission due to limited flexibility in scheduling timeslots, leading to potential delays and reduced throughput when multiple access terminals share the same sector.
Innovation Solution
The proposed solution involves an access terminal requesting data transmission from both a primary and a secondary sector, allowing the access network to determine if available timeslots in the secondary sector can be used for data transmission, thereby optimizing scheduling and reducing delays.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the access network uses only the primary sector for data transmission, then the scheduling is simple and straightforward, but the sector throughput is reduced and scheduling delays increase when timeslots are occupied
Solution Approach 1:
The patent introduces a secondary sector as an additional dimension for data transmission. When the primary sector's timeslots are occupied, the access terminal can receive data from the secondary sector, effectively adding a spatial dimension to the communication system to overcome scheduling constraints.
Solution Approach 2:
The patent implements dynamic sector selection where the access terminal can switch between primary and secondary sectors based on real-time availability. The terminal monitors both sectors and dynamically chooses the appropriate sector for data reception, making the system adaptive to changing conditions.
2Productivity
If the access network schedules more timeslots for other access terminals in the primary sector, then other terminals get better service, but the access terminal experiences increased scheduling delays
Solution Approach 1:
The access terminal performs preliminary monitoring of both primary and secondary sector timeslots before data transmission is needed. By advance knowledge of which secondary timeslots are available, the terminal can prepare to receive data from the secondary sector, reducing actual waiting time when primary sector timeslots are occupied.
Solution Approach 2:
The patent creates a backup data transmission path through the secondary sector. The access network can transmit data to the terminal via the secondary sector as a copy or alternative route when the primary path is unavailable, ensuring data delivery without excessive delay.
3Adaptability or versatility
If the access terminal monitors and requests data from multiple sectors, then scheduling flexibility and throughput improve, but the terminal complexity and processing requirements increase
Solution Approach 1:
The patent divides the monitoring and data reception functions into segments: the primary sector handles main data transmission while the secondary sector provides supplementary transmission. The terminal processes each sector separately, managing complexity by segmenting the multi-sector operation into distinct, manageable components.

AI summary
An improved mechanism for managing allocation of air interface timeslots for transmission of data to access terminals. When an access terminal requests an access network to transmit data to the access terminal in a first sector, the access terminal will identify within its request a second sector that the access network can optionally use instead. The access network will then determine whether a threshold number of upcoming timeslots in the first sector are already scheduled to carry data to other access terminals and whether at least one of those timeslots is available for use in the second sector. If so, the access network will then responsively transmit the data to the access terminal in the at least one timeslot on the second sector. Advantageously, this process can help to increase sector throughput.
