Blank Symbol Configuration for Interference Avoidance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current mobile communication technologies face inefficiencies in avoiding interference between base stations, particularly when configuring subframes, leading to resource wastage and delayed communication progress.
Innovation Solution
Configuring specific symbols within a subframe as blank symbols based on received configuration information from adjacent base stations to prevent interference, rather than configuring entire subframes as blank, thereby saving resources and reducing communication delays.

Engineering Contradiction Analysis
1Object-affected harmful factors
If entire subframes are configured as blank subframes to avoid interference, then interference avoidance is improved, but resource utilization deteriorates and communication delay increases
Solution Approach 1:
The patent segments the subframe structure by introducing the concept of blank symbols within subframes. Instead of making entire subframes blank, only specific symbols that cause interference are configured as blank symbols. This segmentation allows non-interfering symbols to remain active for communication, thus improving resource utilization while maintaining interference avoidance.
Solution Approach 2:
The patent applies local quality by differentiating treatment across different symbols within a subframe. Symbols that cause interference to downstream transmissions are configured as blank, while symbols that do not cause interference remain active for communication. This localized approach ensures that only necessary resources are blanked, optimizing both interference avoidance and communication efficiency.

If entire subframes are configured as blank subframes to avoid interference, then interference avoidance is improved, but time resource utilization deteriorates
Solution Approach 1:
The patent segments the subframe structure by introducing the concept of blank symbols within subframes. Instead of making entire subframes blank, only specific symbols that cause interference are configured as blank symbols. This segmentation allows non-interfering symbols to remain active for communication, thus improving resource utilization while maintaining interference avoidance.
Solution Approach 2:
The patent applies partial action by configuring only the necessary symbols as blank that actually cause interference, rather than blanking entire subframes. This partial approach minimizes the loss of time resources while achieving sufficient interference avoidance, thereby reducing communication delay.

AI summary
The present disclosure provides a communication method and device, which belong to a technical field of mobile communication. The communication method includes: receiving, by a second base station, symbol configuration information of a first base station, wherein the symbol configuration information is used to indicate an upstream/downstream symbol configuration in a subframe; configuring, by the second base station, a specified symbol in a subframe of the second base station as a blank symbol according to the symbol configuration information of the first base station and symbol configuration information of the second base station, wherein the specified symbol is a symbol that is predicted to cause interference during communication; and communicating, by the second base station, according to reconfigured symbol configuration information. Embodiments of the present disclosure avoid interference on the communication of the first base station on downstream symbols by configuring a symbol that is predicted to cause interference during the communication of the second base station as a blank symbol. Since a symbol is a smaller time span within a subframe, as compared with related arts, the approach to configure a blank symbol may not only save subframe resources, but also would not cause too much delay in a communication progress of the second base station. Therefore, communication efficiency is improved.
