Communication method, network nodes and radio access network system

Abstract

The application provides a communication method, network nodes, and a radio access network system. The method is applied to a radio access network system comprising a first network node and a second network node, wherein the first network node and the second network node communicate with each other through a first communication interface. The method includes the following steps that: the first network node receives first configuration information from the second network node, wherein the first configuration information contains a serving cell set configured for a terminal device, the first configuration information indicates the statuses of auxiliary cells, and the first configuration information is generated by the second network node in a first protocol layer; the first network node sends the first configuration information to the terminal device; the first network node sends first indication information to the terminal device, wherein the first indication information contains the information of the statuses of at least one auxiliary cell which belongs to the serving cell set, and the first indication information is generated by the first network node in a second protocol layer.

Description

technical field [0001] The present application relates to the communication field, and more particularly, to a communication method, a network node and a wireless access network system. Background technique [0002] In order to further increase the transmission bandwidth, a carrier aggregation (carrier aggregation, CA) technology is introduced into Long Term Evolution-Advanced (LTE-A). Carrier aggregation mainly aggregates multiple carrier units (component carriers, CCs, or component carriers, component carriers, etc.) into one carrier with relatively large bandwidth to support high-speed data transmission. In the current technology, the base station can configure the carrier aggregation and determine the activation / deactivation state of the secondary cell, and notify the terminal device through signaling. [0003] However, with the development of the fifth generation (5G) communication network, the network architecture has changed, for example, the introduction of centrali...

Problems solved by technology

[0004] Under the new network architecture, the original carrier aggregation configuration method is no longer applicable. How to configure carrier aggregation for terminal devices under this new network architecture has become an urgent technical problem to be solved.
