Method for performing communication by using spectrum resource and communications device
First Claim
1. A method for performing communication by using a spectrum resource, comprising:
- determining, by a first communications device in a first communications system, a first sub-timeslot and a second sub-timeslot in a unit timeslot; and
performing, by the first communications device, communication in the first sub-timeslot by using the spectrum resource, wherein the first communications device has a priority higher than that of a second communications device in a second communications system in the first sub-timeslot, and, wherein the first communications device has a priority lower than that of the second communications device in the second sub-timeslot;
wherein before determining the first sub-timeslot and the second sub-timeslot in the unit timeslot, the method further comprises;
determining, by the first communications device, a duration of the unit timeslot; and
dividing, by the first communications device, the spectrum resource into multiple unit timeslots in a time domain according to the determined duration of the unit timeslot, wherein the unit timeslot is one of the multiple unit timeslots; and
wherein determining the first sub-timeslot and the second sub-timeslot in the unit timeslot comprises;
determining, by the first communications device, percentages of the first sub-timeslot and the second sub-timeslot in the unit timeslot based on current traffic load information of the first communications device and/or current traffic load information of the second communications device; and
dividing, by the first communications device, each unit timeslot of the multiple unit timeslots into the first sub-timeslot and the second sub-timeslot according to the determined percentages of the first sub-timeslot and the second sub-timeslot in the unit timeslot.

Abstract
Embodiments of the present invention provide a method for performing communication by using a spectrum resource, and a communications device. The method includes: determining, by a first communications device in a first communications system, a first sub-timeslot and a second sub-timeslot in a unit timeslot; and performing, by the first communications device, communication in the first sub-timeslot by using a spectrum resource at a priority higher than that of a second communications device in a second communications system, where a priority at which the first communications device uses the spectrum resource in the second sub-timeslot is lower than a priority at which the second communications device uses the spectrum resource in the second sub-timeslot. The embodiments of the present invention can improve utilization of spectrum resources.
