Embodiment Construction

[0124] The technical solution in this application will be described below with reference to the accompanying drawings.

[0125] In order to facilitate the understanding of this application, first combine figure 1 Briefly explain the protocol stack structure in LTE. figure 1It is a schematic diagram of the structure of the protocol stack in LTE. As shown in the figure, the current LTE protocol stack structure may include five protocol layers, which are RRC layer, PDCP layer, RLC layer, MAC layer and PHY layer from top to bottom. Signaling generated at any protocol layer of the sending end device (for example, denoted as protocol layer A, it can be understood that protocol layer A can be any protocol layer in the RRC layer, PDCP layer, RLC layer, MAC layer, and PHY layer) All need to be processed by the lower protocol layer, and finally sent to the receiving end device through the physical channel. Correspondingly, the signaling received by the receiving device on the physica...

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...
