5G new radio (NR) time division duplexing frame structure management for heavy uplink traffic site
According to aspects herein, methods and systems for time division duplexing (TDD) management in New Radio (NR) are provided. The method begins with determining if a cell site has heavy uplink use. This can be shown by the cell site using a heavy uplink TDD pattern, which is indicative of users transmitting more data then they receive. Once a cell site has been found to have heavy uplink use, a list of neighboring cell sites is retrieved. The neighboring cell sites may be analyzed to determine if they have heavy downlink use. The method then proceeds to determine if the neighboring cell sites with heavy downlink use can be downlink blanked. Downlink blanking on the neighboring cell sites may then be turned on.
1. A method for time division duplex (TDD) management, the method comprising the steps of:
determining if a cell site has heavy uplink use, wherein the determining if the cell site has heavy uplink use is based on use of a heavy uplink TDD pattern;
retrieving a list of neighboring cell sites;
determining if the neighboring cell sites have heavy downlink use;
determining if the neighboring cell sites with heavy downlink use also have low uplink use and can be downlink blanked; and
dynamically turning on and off downlink blanking on the neighboring cell sites.
2. The method of claim 1 , wherein dynamically turning downlink blanking on and off uses a self-organizing network.
3. The method of claim 1 , wherein the determining if the neighboring cell sites have heavy downlink use is based on the cell site using a heavy downlink TDD pattern.
4. The method of claim 1 , wherein retrieving a list of neighboring cell sites uses automatic neighbor relations.
5. The method of claim 1 , further comprising turning off downlink blanking on the neighboring cell sites.
6. The method of claim 5 , wherein turning off downlink blanking occurs when the cell site with heavy uplink use no longer has heavy uplink use.
7. The method of claim 6 , further comprising implementing a heavy downlink TDD pattern on the cell site that had heavy uplink use.
8. A non-transitory computer-readable storage media having computer-executable instructions embodied thereon, that when executed by one or more processors, cause the one or more processors to:
determining if a cell site has heavy uplink use, wherein the determining if the cell site has heavy uplink use is based on use of a heavy uplink TDD pattern;
retrieving a list of neighboring cell sites;
determining if the neighboring cell sites have heavy downlink use;
determining if neighboring cell sites with heavy downlink use also have low uplink use and can be downlink blanked; and
dynamically turning on and off downlink blanking on the neighboring cell sites.
9. The computer-readable storage media of claim 8 , wherein dynamically turning downlink blanking on and off uses a self-organizing network.
10. The computer-readable storage media of claim 8 , wherein the determining if the neighboring cell sites have heavy downlink use is based on the cell site having a heavy downlink TDD pattern.
11. The computer-readable storage media of claim 8 , wherein retrieving a list of neighboring cell sites uses automatic neighbor relations.
12. The computer-readable medium of claim 8 , further comprising turning off downlink blanking on the neighboring cell sites.
13. The computer-readable medium of claim 12 , wherein turning off downlink blanking occurs when the cell site with heavy uplink use no longer has heavy uplink use.
14. A system for time division duplex (TDD) management, the system comprising:
a cell site;
multiple neighboring cell sites;
a mobile device having heavy uplink use on the cell site;
a network component configured to communicate with the cell site;
a processor; and
one or more computer storage hardware devices storing computer-useable instructions that, when used by the processor, cause the processor to:
determine if the cell site has heavy uplink use, wherein the determining if the cell site has heavy uplink use is based on use of a heavy uplink TDD pattern;
retrieve a list of neighboring cell sites;
determine if the neighboring cell sites have heavy downlink use;
determine if neighboring cell sites with heavy downlink use also have low uplink use and can be downlink blanked; and
dynamically turning on and off downlink blanking on the neighboring cell sites.
15. The system of claim 14 , wherein dynamically turning downlink blanking one and off uses a self-organizing network.
