Abstract

A frequency spectrum coordination device and method, and a device and a method in a wireless communication system. The frequency spectrum coordination device, used for coordinating usage of shared wireless transmission resources by multiple systems, includes: an acquirement unit, configured to acquire a usage state of the shared wireless transmission resources; and an allocation unit, configured to allocate, according to the usage state, the shared wireless transmission resources for a communication device based on the influence of resource elements to be allocated of one system in multiple systems on the available resource elements of other systems in multiple systems, and the resource allocation granularity of one system is smaller than the resource allocation granularity of other systems.

Claims

1. An electronic apparatus for coordinating use of shared radio transmission resources by a plurality of systems, the electronic apparatus comprising one or more processors configured to:

acquire use status of the shared radio transmission resources; and

allocate, according to the use status, the shared radio transmission resources to communication equipment based on influence of to-be-allocated resource elements of one system of the plurality of systems on available resource elements of an other system in the plurality of systems, such that a sum of a first number of the available resource elements and a second number of occupied resource elements of the other system is not smaller than a third number of preserved resource elements of the other system,

wherein a resource allocation granularity of the one system is finer than a resource allocation granularity of the other system.

2. The electronic apparatus according to claim 1, wherein the one or more processors are further configured to allocate, based on a resource request from communication equipment in the one system of the plurality of systems, the shared radio transmission resources to the communication equipment in the one system.

3. The electronic apparatus according to claim 2, wherein the resource request comprises at least one of a traffic requirement, geographical location information, or a resource use priority.

4. The electronic apparatus according to claim 2, wherein the electronic apparatus is implemented in a base station in the one system, and the electronic apparatus further comprises:

circuitry configured to receive the resource request from the communication equipment in the one system, and notify the allocated resources to the communication equipment in the one system.

5. The electronic apparatus according to claim 1, wherein the one or more processors are further configured to:

divide the shared radio transmission resources based on influence of the one system on resource availability of the other system; and

allocate resources to the communication equipment according to the dividing of the shared radio transmission resources.

6. The electronic apparatus according to claim 2, wherein the one or more processors are further configured to allocate resources to the communication equipment in the one system from the to-be-allocated resource elements according to use conditions of occupied resource elements of the one system, the occupied resource elements of the one system corresponding to same resource element of the other system as the to-be-allocated resource elements, and/or to allocate resources to the communication equipment in the one system according to a resource use habit of the other system to reduce resource use collision with the other system.

7. The electronic apparatus according to claim 3, wherein the one or more processors are further configured to determine a use period of the resources allocated to the communication equipment in the one system according to a use period of the occupied resource elements of the one system.

8. The electronic apparatus according to claim 1, wherein the one or more processors are further configured to acquire the use status in at least one of the following manners:

information interacting, spectrum sensing, or broadcast querying.

9. The electronic apparatus according to claim 1, wherein the use status comprises occupied resources of the shared radio transmission resources.

10. The electronic apparatus according to claim 9, wherein the use status further comprises a type of communication equipment occupying the occupied resources, and in a case that the type of the communication equipment occupying the occupied resources is communication equipment in the one system, the use status further comprises a number of the communication equipment in the one system occupying the occupied resources.

11. The electronic apparatus according to claim 4, wherein the circuitry is further configured to receive information on resources selected to be used from the allocated resources by the communication equipment in the one system.

12. The electronic apparatus according to claim 1, wherein the one system is an LTE system, and the other system is one or more of a WI-FI system, a broadcast television system, a radar system, or an infrared system.

13. An electronic apparatus in a wireless communication system, the electronic apparatus comprising one or more processors configured to:

send a resource request to a spectrum coordinator;

receive resources allocated by the spectrum coordinator in response to the resource request; and

select resources to be used from the allocated resources according to a service quality requirement;

wherein the spectrum coordinator is used for coordinating use of shared radio transmission resources by a plurality of systems comprising the wireless communication system, and the allocated resources are allocated by the spectrum coordinator based on influence of to-be-allocated resource elements of the wireless communication system on available resource elements in an other system of the plurality of systems, such that a sum of a first number of the available resource elements and a second number of occupied resource elements of the other system is not smaller than a third number of preserved resource elements of the other system, and

wherein a resource allocation granularity of the wireless communication system is finer than a resource allocation granularity of the other system.

14. The electronic apparatus according to claim 13, wherein the one or more processors further receive from the spectrum coordinator a use period of the allocated resources.

15. The electronic apparatus according to claim 13, wherein the resource request comprises at least one of a traffic requirement, geographical location information, or a resource use priority.

16. The electronic apparatus according to claim 13, wherein the one or more processors are further configured to notify information on the resources selected to be used to the spectrum coordinator.

17. The electronic apparatus according to claim 13, wherein:

the resource request is a spectrum sensing request; and
