Abstract

The embodiment of the invention discloses a method for adjusting auxiliary primary cells and an evolved NodeB, and belongs to the field of communication. The auxiliary primary cells can be adjusted in the carrier aggregation process, and communication efficiency is improved. The method for adjusting the auxiliary primary cells comprises the steps that a primary evolved NodeB determines and changes the first auxiliary primary cell with services provided by a secondary radio bearer, and the second auxiliary primary cell is selected from the cells with services provided by the secondary radio bearer; the primary evolved NodeB sends first messages to the secondary radio bearer, and the first messages are used for requesting the secondary radio bearer to adjust the auxiliary primary cells and comprise the identification of the second auxiliary primary cell; the primary evolved NodeB sends second messages to UE, and the second messages are used for requesting the UE to use the secondary auxiliary primary cell.

Description

technical field

[0001] The present invention relates to the communication field, in particular to a method for adjusting an auxiliary primary cell and a base station. Background technique

[0002] With the development of the mobile communication system, the transmission rate and service quality that the communication system can provide are getting higher and higher, and users also put forward higher requirements on the transmission rate. In order to ensure the speed of most users and provide higher throughput for some users without greatly increasing the configured bandwidth, the 3rd Generation Partnership Project (3GPP) introduced carrier aggregation (Carrier Aggregation). Aggregation, referred to as CA) technology. Carrier aggregation means that a user terminal (User Equipment, UE for short) can simultaneously use multiple component carriers (Component Carrier, CC for short) for uplink and downlink communication, thereby supporting high-speed data transmission. When the ...
