Wireless Time Slot Allocation for Millimeter Wave Interference
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In wireless communication systems, especially those using millimeter waves, the allocation of time slots for multiple apparatuses in the same receive beam direction often results in communication conflicts, leading to reduced reception quality due to increased interference.
Innovation Solution
The method involves dynamically allocating time for each receive beam direction based on the number and location of apparatuses, allowing for targeted beamforming and reduced interference by dividing the access period into segments corresponding to specific receive beam directions with known apparatuses, thereby minimizing conflicts and enhancing signal-to-noise ratios.

Engineering Contradiction Analysis
1Productivity
If time slots are allocated to multiple apparatuses in the same receive beam direction, then the system can support more simultaneous communications, but communication conflicts and interference increase, reducing reception quality
Solution Approach 1:
The patent segments the receive beam directions into distinct groups, where each group is assigned to a specific time slot. This segmentation prevents multiple apparatuses in the same beam direction from transmitting simultaneously, thereby eliminating interference while still supporting multiple concurrent communications across different time slots and beam directions.
2Ease of operation
If time slots are allocated without considering apparatus locations in beam directions, then the allocation process is simpler, but interference levels increase and reception quality deteriorates
Solution Approach 1:
The patent performs preliminary action by pre-identifying and categorizing apparatuses according to their receive beam directions before time slot allocation. This preliminary classification enables the system to automatically assign time slots based on beam direction groups, maintaining operational simplicity while ensuring that apparatuses in the same beam direction do not transmit simultaneously, thus preserving high reception quality.

AI summary
Various methods and apparatuses for transmitting an allocation of time in a wireless communication system are disclosed. In one aspect, an allocation of time for receiving communications via a receive beam direction is transmitted. The allocation of time may be based on information regarding an apparatus known to be located in the receive beam direction. A unique time for receiving communications from each known apparatus may be allocated, or a duration of time for receiving communications from the known apparatuses may vary based on a number of apparatuses known to located in a receive beam direction.
