Abstract

The embodiment of the invention discloses a data transmission method, and the method comprises the following steps that a first wireless network node reminds the bearing type of a downlink data packet; the first wireless network node transmits the downlink data packet to a second wireless network node under the condition that the bearing type is the signaling radio bearing SRB so that the second wireless network node performs the function of a grouped data aggregation protocol PDCP layer for the downlink data packet; or the first wireless network node performs a function of a PDCP layer for the downlink packet and transmits the processed downlink packet to the second radio network node under the condition that the bearing type is a data radio bearer DRB. Correspondingly, the embodiment of the present invention also discloses a wireless network node that can reduce transmission bandwidth and time delay requirements.

Description

technical field [0001] The invention relates to the communication field, in particular to a data transmission method, a wireless network node and a communication system. Background technique [0002] With the exponential growth of services, mobile networks are evolving towards 5G mobile networks. 5G networks need to provide greater bandwidth and higher spectral efficiency to support the explosive growth of services. Higher data volumes can be efficiently delivered using ultra-dense, low-power small cell networks. However, with dense network deployment, inter-cell interference will increase and the interference scenarios will become more complex. In order to solve the above problems, a centralized processing scheme C-RAN is proposed, which can effectively solve the interference problem and load balance among small stations, thereby effectively enhancing the system capacity. The C-RAN system consists of an RRU (Remote Radio Unit, RRU for short) and a BBU pool. The BBU pool ...
