Base Station Frequency Allocation Control Signal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional wireless communication systems face inefficiencies in resource allocation, particularly when supporting both continuous and discrete frequency allocation schemes, leading to increased processing requirements and reduced transmission efficiency.
Innovation Solution
A communication system that allocates resource blocks using both continuous and discrete schemes, where the base station informs the user terminal of the allocation method through a control signal, allowing discrete allocation only when the number of resource blocks falls within specific thresholds, and dividing resource blocks into sub-blocks with a minimum interval of one resource block.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a base station performs different processing to notify wireless resources for discrete frequency allocation, then discrete frequency allocation can be supported, but the amount of processing increases
Solution Approach 1:
The patent makes the existing continuous allocation notification mechanism serve dual purposes by interpreting the same notification bits differently based on a mode indicator. When the mode indicator shows continuous allocation, the notification works as before; when it shows discrete allocation, the same notification structure is reinterpreted to convey discrete resource block information, eliminating the need for separate processing paths
Solution Approach 2:
The patent changes the interpretation parameter (mode indicator) to switch between continuous and discrete allocation modes. By modifying how the notification bits are interpreted rather than changing the notification structure itself, the system supports both allocation types without increasing processing complexity
2Adaptability or versatility
If a notification other than continuous frequency allocation notification is transmitted for discrete frequency allocation, then discrete resource allocation can be indicated, but transmission efficiency decreases
Solution Approach 1:
The existing continuous allocation notification format is made multi-functional by introducing a mode indicator that determines how the same notification bits are interpreted. This eliminates the need for separate notification messages for discrete allocation, maintaining transmission efficiency while enabling flexible resource allocation
Solution Approach 2:
The patent merges the continuous and discrete allocation notification mechanisms into a single unified notification structure. By combining both allocation types into one notification process with a mode indicator, the system avoids the overhead of separate notification channels while supporting both allocation methods

AI summary
A communication system in which a base station selects any one of a continuous allocation scheme of allocating frequency bands continuously and a discrete allocation scheme of allocating frequency bands discretely and performs allocation of frequency bands to a user terminal. If the discrete allocation scheme is selected, the base station divides the frequency bands to be allocated into sub blocks on the basis of predetermined discrete allocation information for imposing a constraint on a discrete allocation state, and generates a control signal on the basis of the discrete allocation information (S12, S13), the control signal being intended to notify a result of allocation where arrangement on a frequency axis is determined in units of sub blocks. The user terminal determines the frequency bands allocated to the own terminal on the basis of the discrete allocation information retained and a control signal received from the base station.
