Abstract

A resource allocation method and a resource allocation device are provided. The first base station receives first information transmitted by the second base station, the first information includes identification information of the UE, identification information of a first serving cell of the UE, and service frequency of the first serving cell, and the second base station is a serving base station of the first serving cell. If the first base station determines that the UE is self-interfered, the first base station transmits notification information to the second base station, the notification information is used to negotiate with the second base station to allocate a different resource to the UE.

First claim

1 . A resource allocation method, wherein a user equipment (UE) accesses a first base station and a second base station, the method comprises:
receiving, by the first base station, first information transmitted by the second base station, wherein the first information comprises identification information of the UE, identification information of a first serving cell of the UE, and service frequency of the first serving cell, and the second base station is a serving base station of the first serving cell; and transmitting, if the first base station determines that the UE is self-interfered based on the first information, notification information to the second base station, wherein the notification information is used to negotiate with the second base station to allocate a different resource to the UE.

2 . The method according to claim 1 , wherein after transmitting the notification information to the second base station, the method further comprise:
receiving a response message from the second base station, wherein the response message is used to indicate the resource allocated by the second base station to the UE.

3 . The method according to claim 1 , wherein the receiving, by the first base station, first information transmitted by the second base station comprises:
receiving, by a centralized unit (CU) of the first base station, first information transmitted by the second base station and transmitting the first information to a distributed unit (DU) of the first base station through a first interface, where the first interface is an interface between the CU and the DU.

4 . The method according to claim 3 , wherein the determining, by the first base station, that the UE is self-interfered based on the first information comprising:
receiving, by the DU, the first information through the first interface, and determining the self-interference of the UE based on the first information.

5 . The method according to claim 4 , wherein transmitting the notification information to the second base station comprises:
transmitting, by the DU, the notification information to the CU through the first interface; receiving, by the CU, the notification information through the first interface and transmitting the notification information to the second base station.

6 . The method according to claim 4 , wherein transmitting the notification information to the second base station comprises:
transmitting, by the DU, second information to the CU through the first interface; wherein the second information includes identification information of the UE, identification information of a second serving cell of the UE, and a first resource allocated by the first base station to the UE, the first base station is a serving base station of the second serving cell; receiving, by the CU, the second information through the first interface and transmitting the notification information to the second base station based on the second information.

7 . The method according to claim 6 , wherein after receiving the response message transmitted by the second base station, the method further comprises:
transmitting, by the CU, resource indication information to the DU through the first interface based on the response message, wherein the resource indication information includes the identification information of the UE, the identification information of the second serving cell of the UE, and the resource allocated by the second base station to the UE; receiving, by the DU, the resource indication information through the first interface and allocating the resource to the UE based on the resource indication information.

8 . The method according to claim 1 , wherein the notification information comprises second information, the second information is used to instruct the second base station to allocate a resource different from the first resource to the UE, the second information includes identification information of the UE, and identification information of a second serving cell and a first resource allocated by the first base station to the UE, the first base station is a serving base station of the second serving cell.

9 . The method according to claim 1 , wherein the notification information comprises information of the second resource, and the information of the second resource is used to instruct the second base station to allocate a second resource to the UE, the second resource is different from the first resource, and the first resource is the resource allocated by the first base station to the UE.

10 . The method according to claim 6 , wherein the notification information further comprises a start use time and a stop use time of the first resource.

11 . The method according to claim 6 , wherein the notification information further comprises second indication information, the second indication information is used to indicate that the first resource is a dedicated resource of the UE; or, is used to indicate that the first resource is a common resource of N UEs, the N UEs include the UE, and the N UEs are all in the second serving cell of the UE, and N is a positive integer greater than or equal to 2.

12 . The method according to claim 1 , wherein the resource comprises at least one of a time slot, a half time slot, a sub-frame, a frame, a physical resource block (PRB), a PRB group, or Bandwidth Part (BWP).

13 . The method according to claim 1 , wherein the first base station is a master serving base station of the UE.

14 . A resource allocation method, wherein a UE accesses a first base station and a second base station, the method comprises:
transmitting, by the second base station, first information to the first base station, wherein the first information includes identification information of the UE, identification information of a first serving cell of the UE, and service frequency of the first serving cell, and the second base station is a serving base station of the first serving cell; receiving, by the second base station, notification information transmitted by the first base station, and the notification information is used to negotiate with the second base station to allocate a different resource to the UE.

15 . The method according to claim 14 , wherein after allocating, by the second base station, a resource to the UE based on the notification information, the method further comprises:
transmitting, by the second base station, a response message to the first base station, wherein the response message is used to indicate the resource allocated by the second base station to the UE.

16 . The method according to claim 14 , wherein the notification information comprises second information, the second information is used to instruct the second base station to allocate a resource different from the first resource to the UE, wherein the second information includes identification information of the UE, the identification information of a second serving cell and a first resource allocated by the first base station to the UE, the first base station is a serving base station of the second serving cell;
the allocating, by the second base station, the resource to the UE based on the notification information comprises allocating, by the second base station, a resource different from the first resources to the UE based on the second information.

17 . The method according to claim 14 , wherein the notification information comprises information of the second resource, and the information of the second resource is used to instruct the second base station to allocate a second resource to the UE,
