Abstract

The present invention provides an entity configuration method, device and system, and CU-U; wherein, the entity configuration method includes: obtaining, through an Xn interface, the configuration information for each Packet Data Convergence Protocol PDCP entity that processes data radio bearers Specified information, wherein, the Xn interface is the interface between the PDCP entity CU-C on the control plane and the PDCP entity CU-U on the user plane; each PDCP entity is configured according to the specified information. Through the present invention, the problem of how to realize the configuration of the CU‑U protocol entity is solved, and centralized service aggregation is realized.

Description

technical field [0001] The present invention relates to the field of wireless communication, in particular to an entity configuration method, device and system, and a CU-U. Background technique [0002] In the fifth generation (5G for short) mobile communications, massive connections and higher rate requirements for users require the baseband processing unit (Building Baseband Unit, BBU for short) and remote radio frequency in long term evolution (Long Term Evolution, short for LTE). The transmission capacity of the fronthaul interface Common Public Radio Interface (CPRI) between Remote Radio Units (RRU for short) poses a great challenge, because the CPRI interface transmits after processing such as physical layer coding For IQ signals, the CPRI interface has relatively large requirements for transmission delay and bandwidth. If the 5G air interface rate increases to tens of Gbps, the traffic demand of the CPRI interface will rise to the Tbps level, which will bring huge pr...
