Embodiment Construction

[0064] figure 2 An access network protocol stack solution for 5G requirements is shown, and the protocol stack solution is applicable to the embodiment of the present invention. The protocol layer of the control plane includes the RRC (Radio Resource Control, radio resource control) layer, and the protocol layer of the user plane includes the PDCP (Packet Data Convergence Protocol, packet data convergence protocol) layer, RLC (Radio Link Control, radio link control) layer , MAC (Media Access Control, media access control) layer and PHY (Physical Layer, physical layer).

[0065] For the distributed network architecture, the InterCell (inter-cell) MAC protocol layer and the DDR (DataDistribution&Reordering, data distribution / reordering) protocol layer are newly added; the RRC protocol layer adds the function of air interface signaling; the mutually exclusive RLCcenter layer is added And the RLCremote protocol layer, that is, when RLCcenter exists, RLCremote does not exist.

Abstract

The invention discloses an RCC, an RRS and a distributed base station system. The RCC is provided with N functional modules, and links of a first type and / or a second type are built between each functional module and M RRSs (radio remote systems). The links of the first type are used for transmitting control plane data, and the links of the second type are used for transmitting the data of a data plane, wherein N and M are integers greater than or equal to one. The RRS is provided with a user radio resource control distribution intersection module, and a link of the first type or the second type is built between the user radio resource control distribution intersection module and a radio cloud center RRC. The link of the first type is used for transmitting the data of a control plane, and the link of the second type is used for transmitting the data of the data plane. The distributed base station comprises the above RCC and M RRSs.

Description

technical field [0001] The invention relates to the communication field, in particular to an RCC, RRS and distributed base station system. Background technique [0002] Based on the C-RAN (Centralized, Cooperative, Cloud & Clean-Radio Access Network, centralized, collaborative, cloud architecture, green radio access network) cloud platform, the NGFI (Next Generation Fronthaul Interface) network architecture is aimed at 2G / Various 3G / 4G and 5G scenarios can be covered through flexible fronthaul interfaces, such as figure 1 shown. [0003] figure 1 It shows an expected distributed network architecture in a 5G scenario, where RCC (Radio Cloud Center, wireless cloud center) and RRS (Remote Radio System, wireless remote system) are connected through a transmission network. Based on this network architecture, an expected interaction process between RCC and RRS is as follows: RCC completes big data calculations, and then sends instructions to RRS, and RRS completes resource all...
