Problems solved by technology

[0004] However, when the UE transmits signals on the 1.8GHz uplink and the 3.5GHz uplink at the same time, the 1.8GHz uplink and the 3.5GHz uplink will generate intermodulation interference, which will affect the UE's 1.8GHz downlink In addition, the second harmonic of the 1.8GHz uplink signal will also affect the reception of the UE's downlink signal at 3.5GHz; that is, intermodulation interference and second harmonic interference will cause UE self-interference

Abstract

Disclosed are a resource allocation method and device, which relate to the technical field of communications, and can avoid the problem of UE self-interference when a UE accesses a first base stationand a second base station at the same time. According to the specific scheme, a first base station receives first information sent by a second base station; Wherein the first information comprises theidentification information of the UE, the identification information of the first serving cell of the UE and the service frequency of the first serving cell, and the second base station is the serving base station of the first serving cell; And if the first base station determines that the UE self-interferes according to the first information, sending notification information to the second base station, the notification information being used for negotiating with the second base station to distribute different resources to the UE.

Description

technical field [0001] The present application relates to the field of communication technologies, and in particular to a resource allocation method and device. Background technique [0002] For the fifth-generation mobile communication technology (5-Generation, 5G), in the standard discussion of the New Radio Access Technology (NR), the 5G system and the LTE system can be coupled in a dual connectivity (Dual Connectivity, DC) manner , forming a double-connection system. [0003] Among them, during dual connectivity, 1.8GHz LTE spectrum and 3.5GHz 5G spectrum can be used for dual connectivity, and user equipment (User Equipment, UE) can simultaneously transmit signals on the 1.8GHz uplink and 3.5GHz uplink . [0004] However, when the UE transmits signals on the 1.8GHz uplink and the 3.5GHz uplink at the same time, the 1.8GHz uplink and the 3.5GHz uplink will generate intermodulation interference, which will affect the UE's 1.8GHz downlink In addition, the second harmonic...
