Embodiment Construction

[0023] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the embodiments and accompanying drawings.

[0024] The basic idea of ​​the present invention is that each RRU is composed of one or more radio frequency remote ends and an IR processing unit. Wherein, multiple radio frequency remote ends are placed on the side of the antenna, each radio frequency remote end is connected to an antenna, and the IR processing unit can be placed indoors. The remote radio frequency and the IR processing unit are connected by a Category 5 super cable. Correspondingly, power modules are respectively set in the remote radio frequency and the IR processing unit; the power module included in the IR processing unit provides power to the IR processing unit, and The above-mentioned five-category line is connected, and at the same time, power is supplied to the radio freq...

Abstract

The invention provides a radio remote unit (RRU). The RRU comprises at least one radio remote and an interface (IR) processing unit, wherein each radio remote is connected with the IR processing unit through a CAT5E wire and connected with an antenna to process received uplink analog radio frequency signals into uplink data containing uplink digital intermediate frequency signals and send the data to the IR processing unit from which downlink data containing downlink digital intermediate frequency signals is received and processed into downlink analog radio frequency signals which are sent tothe antenna; and the IR processing unit processes uplink data, which contain uplink digital intermediate frequency signals and are from each radio remote, into uplink digital baseband signals which are sent to a BBU and processes downlink digital baseband signals from the BBU into downlink data which contain downlink digital intermediate frequency signals and send the downlink data through a ratio remote. The RRU can perform the coverage by using a plurality of ratio remotes, thereby expanding the transmission capacity.

Description

technical field [0001] The present invention relates to mobile communication technology, is especially applied in time division synchronous code division multiple access (TD-SCDMA, Time Division-Synchronous Code Division Multiple Access) system and time division long-term evolution (TD-LTE, Time Division-Long Term Evolution) system A remote radio unit (RRU, Radio Remote Unit). Background technique [0002] At present, in the TD-SCDMA system and the TD-LTE system, the RRU and the baseband processing unit (BBU, Building Base band Unit) are commonly used to form a distributed base station architecture. figure 1 It is a schematic diagram of an existing RRU structure. Such as figure 1 As shown, one BBU is connected to one or more RRUs, figure 1 Taking one BBU connected to two RRUs as an example, the BBU and the RRU are connected through an optical fiber. Correspondingly, both the BBU and the RRU include an optical transceiver connected to the optical fiber. The RRU is connect...
