Problems solved by technology

[0009] In the TD-SCDMA system, in order to achieve a better data dynamic range, each data stream in the user data should be sampled with 16 bits. At this time, when using the frame structure of the CPRI protocol to realize the data interaction between the REC node and the RE node, Since the control data occupies one word length in a basic frame, only 15 words are actually used to transmit user data, so that the number of data streams for transmitting user data is less than 24, so it cannot meet the typical requirements of the TD-SCDMA system. smart antenna application scenarios; when REC nodes and RE nodes exchange data in a TD-SCDMA system, the rate at which the radio base station processes data streams is relatively low, and the system performance is relatively poor

Embodiment Construction

[0033] Embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0034] In the TD-SCDMA system, a TD-SCDMA frame consists of two TD-SCDMA subframes, such as image 3 As shown, a TD-SCDMA subframe includes business time slots (TS0~TS6), uplink pilot time slots (UpPTS), downlink pilot time slots (DwPTS) and guard intervals (GP); among them, downlink business time slots and downlink pilot time slots are used to transmit downlink data, called downlink time slots; uplink service time slots and uplink pilot time slots are used to transmit uplink data, called uplink time slots.

[0035] Based on the structural features of the above TD-SCDMA subframe, in the embodiment of the present invention, it is considered to partially separate and transmit the data exchanged between the REC node and the RE node. The specific treatment is as follows:

[0036]Among the data interacted between the REC node and the RE node, the operatio...

Abstract

The invention discloses a method of exchanging data between a radio equipment control node and a radio equipment node. The data comprises user data and control data. The control data comprises operational maintenance data. The radio equipment control node transmits downlink operational maintenance data to the radio equipment node in the uplink time slot of a TD-SCDMA sub frame. The radio equipment node transmits uplink operational maintenance data to the radio equipment control node in the downlink time slot of the TD-SCDMA sub frame. The radio equipment control node, the radio equipment nodeand a radio base station system are also disclosed by the invention. With the method adopted, the rate of data streams between the radio equipment control node and the radio equipment node is improved.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a data interaction method, device and system in a radio base station. Background technique [0002] In recent years, with the development of base station design technology in wireless communication systems, the radio equipment control (REC) node and the radio equipment (RE) node in the radio base station tend to be physically separated. For example, the RE node can be close to the antenna, and the REC node is located in the entrance. The REC nodes perform baseband signal processing, while each RE node converts between baseband and radio frequency and transmits or receives information through one or more antennas. The REC node is connected to multiple remote RE nodes through independent dedicated optical links and / or electrical links. Each link transmits data downlink from the REC node to the RE node, and transmits data uplink from the RE node to the REC node. [0003] T...
