A master unit and a remote unit is provided for a multiband transmission system for distributing and combining signals of at least one wireless communication network and at least one digital network. A reference frequency generator is arranged in the master unit, the reference frequency generator being designed to clock a master modem for converting the signals of the at least one digital network. The reference frequency signal emitted by the reference frequency signal is restored via a reference frequency receiver and is used for closing a remote modem that is located there for demodulation.

The invention discloses a method and equipment for data transmission. The method includes: in the uplink direction, subjecting an uplink signal to down-sampling by an RRU (radio remote unit) according to a P/Q ratio to obtain an uplink signal with a second sampling rate, subjecting the down-sampled uplink signal to quantization compressing according to a preset compression ratio, sending the uplink signal subjected to quantization compressing to a BBU (baseband unit), and using the BBU for quantization decompressing of the uplink signal subjected to quantization compressing; and in the downlink direction, using the BBU for quantization compressing of a downlink signal with the second sampling rate according to the compression ratio, sending the downlink signal subjected to quantization compressing to the RRU, using the RRU for quantization decompressing of the downlink signal subjected to quantization compressing, and subjecting the downlink signal after quantization decompressing to up-sampling according to a Q/P ratio. By means of combination of down-sampling and quantization compressing, the volume of data transmitted through an interface Ir is effectively compressed.

The present invention discloses a method for processing IQ data of radio-frequency remote unit (RRU), the method comprising: after receiving IQ data sent by a baseband processing unit (BBU) via a dual carrier, the RRU conducts parallel processing on IQ data on the dual carrier, modulates the processed dual carrier into a radio-frequency signal and outputs the signal to an antenna terminal. The present invention discloses an IQ data processing system and a radio-frequency remote unit at the same time. The technical solution of the present invention enhances the capability of an active antenna for transmitting data and reduces cost.

The invention discloses a method for reallocating resources. The method comprises the following steps that: a node base (NodeB) performs strong channel detection on user equipment (UE) and reports the obtained strong channel information of the UE to a radio network controller (RNC); and the RNC reallocates the resources for the UE according to the strong channel information of the UE reported by the NodeB. By the method, dedicated physical channel (DPCH) space division can be realized so as to improve carrier capacity and service quality; and a cell can be formed by performing path combination on a radio remote unit (RRU) with capacity of supporting different frequency bands.

Wideband digital distributed communications systems (DCSs) employing reconfigurable digital signal processing circuit for scaling supported communications services are disclosed. The DCS includes a head-end unit that includes front end downlink signal processing circuit to receive and distribute downlink communications signals for communications services (i.e., communications bands) to remote units. The remote units also include front end uplink signal processing circuits to receive uplink communications signals to be distributed to the head-end unit. The front end signal processing circuits are either equipped with broadband filters, or such filters are eliminated, to allow the DCS to be scaled to pass added communications bands. The front end processing circuits include analog-to-digital conversion (ADC) circuits for converting received analog communications signals into digital communications signals so that the digital communications signals can be processed by digital signal processing circuit that can flexibly be configured and reconfigured to support the added communications bands.
