Abstract

Techniques for asymmetric dynamic spectrum sharing are discussed herein. A first portion of spectrum can share spectrum between Long Term Evolution (LTE) and New Radio (NR) radio access technologies (RATs). A second portion of spectrum can be allocated to a particular RAT without sharing. Thus, control signals associated with both RATs can be associated with the shared portion. However, for the portion not shared, control signals for the particular RAT (e.g., NR) can be used without the control signals from the other RAT (e.g., LTE), thereby increasing capacity in the portion not shared.

First claim

What is claimed is:

1. A system comprising:
one or more processors;
one or more non-transitory computer-readable media storing computer-executable that, when executed, cause the one or more processors to perform operations comprising:
receiving capability information associated with a plurality of user devices associated with a coverage area;
allocating, based at least in part on the capability information, a first portion of a wireless resource to a first radio access technology and a second radio access technology and a second portion of the wireless resource to the second radio access technology, wherein:
the first portion of the wireless resource includes first pilot signals associated with the first radio access technology and second pilot signals associated with the second radio access technology;
the second portion of the wireless resource includes the second pilot signals;
the first portion of the wireless resource is associated with a first portion of spectrum; and
the second portion of the wireless resource is associated with a second portion of spectrum that is asymmetric to the first portion of spectrum;

causing a first base station to transmit the first pilot signals associated with the first portion of the wireless resource; and
causing a second base station to transmit the second pilot signals associated with the first portion and the second portion of the wireless resource.

2. The system of claim 1 , wherein:
the first radio access technology is Long Term Evolution (LTE); and
the second radio access technology is New Radio (NR).

3. The system of claim 1 , wherein the capability information is indicative of:
a first number of the plurality of user devices that support the first radio access technology and the second radio access technology; and
a second number of the plurality of user devices that support dynamic spectrum sharing.

4. The system of claim 1 , wherein a first size of the first portion is different than a second size of the second portion.

5. The system of claim 4 , wherein:
the first portion of the wireless resource comprises 20 MHz of spectrum; and
the second portion of the wireless resource comprises 15 MHz of spectrum that is adjacent to and different from the first portion of the wireless resource.

6. The system of claim 1 , the operations further comprising:
determining at least one of a bandwidth metric or a handover metric associated with the plurality of user devices; and
allocating the first portion and the second portion of the wireless resource based at least in part on the at least one of the bandwidth metric or the handover metric.

7. The system of claim 1 , the operations further comprising:
wherein the capability information is first capability information associated with a first period of time, the operations further comprising:
determining second capability information associated with a second period of time after the first period of time; and
allocating the wireless resource further based at least in part on the second capability information.

8. A method comprising:
receiving capability information associated with a plurality of user devices associated with a coverage area;
performing a first allocation, based at least in part on the capability information, of a first portion of a wireless resource to a first radio access technology and a second radio access technology and a second portion of the wireless resource to the second radio access technology, wherein a first size of the first portion has a first degree of asymmetry to a second size of the second portion;
causing a first base station to transmit with the first portion of the wireless resource;
causing a second base station to transmit with the first portion and the second portion of the wireless resource;
performing a second allocation, based at least in part on the capability information, of the first portion of the wireless resource to the first radio access technology and the second radio access technology and the second portion of the wireless resource to the second radio access technology, wherein, in response to the second allocation, the first size of the first portion has a second degree of asymmetry to the second size of the second portion, the first degree of asymmetry and the second degree of asymmetry being different;
causing the first base station to transmit with the first portion of the wireless resource; and
causing the second base station to transmit with the first portion and the second portion of the wireless resource.

9. The method of claim 8 , wherein:
the first radio access technology is Long Term Evolution (LTE); and
the second radio access technology is New Radio (NR).

10. The method of claim 8 , wherein the capability information is indicative of:
a first number of the plurality of user devices that support the first radio access technology and the second radio access technology; and
a second number of the plurality of user devices that support dynamic spectrum sharing.

11. The method of claim 8 , wherein:
the first portion of the wireless resource includes first pilot signals associated with the first radio access technology and second pilot signals associated with the second radio access technology; and
the second portion of the wireless resource includes the second pilot signals.

12. The method of claim 11 , wherein:
the first portion of the wireless resource comprises 20 MHz of spectrum; and
the second portion of the wireless resource comprises 15 MHz of spectrum that is adjacent to and different from the first portion of the wireless resource.

13. The method of claim 8 , further comprising:
determining at least one of a bandwidth metric or a handover metric associated with the plurality of user devices; and
allocating the first portion and the second portion of the wireless resource based at least in part on the at least one of the bandwidth metric or the handover metric.

14. The method of claim 8 , wherein the capability information is first capability information associated with a first period of time, the method further comprising:
determining second capability information associated with a second period of time after the first period of time; and
allocating the wireless resource further based at least in part on the second capability information.

15. A method comprising:
receiving capability information associated with a plurality of user devices associated with a coverage area;
allocating, based at least in part on the capability information, a first portion of a wireless resource to a first radio access technology and a second radio access technology and a second portion of the wireless resource to the second radio access technology, wherein:
the first portion of the wireless resource includes first pilot signals associated with the first radio access technology and second pilot signals associated with the second radio access technology;
the second portion of the wireless resource includes the second pilot signals;
