The multi-beam antennas 110 and 410 form a multi-beam to emit a transmitted and received signal. Each beam formed is radiated into equally divided spaces in proportion to the number of beams in all directions. Therefore, each beam has a property of being radiated about a different maximum direction angle direction. The number of the multi-beam antennas 110 and 410 is equal to the number of sectors constituting the base station.

The transmission measurement and coupling stages 160 and 440 are terminals capable of externally measuring a transmission output before the system administrator is radiated to the antenna of the system and matching terminals with a radio frequency (RF) monitoring device for remotely monitoring the system administrator. To provide. In addition, it provides a signal entry path to the call estimation module (180,500) for estimating the amount of downlink (call). The signals introduced into the call estimation module 180,500 are synthesized by the beam switching and synthesis / distribution module 140,480 by the multi-beam synthesis / distribution apparatus of the present invention under the control of the sector control module 190,510. Provide criteria for determining distribution.

The transmission measurement and coupling stages 160 and 440 may be configured as one set for each sector or as one module for all sectors. However, it is preferable to configure one set for each sector for compact implementation of the installation and system. Do.

The duplexer module 120 and 420 integrates a band pass function for a transmission signal and a band pass function for a received signal. The duplexer module 120 and 420 enables transmission and reception of a signal to and from the radio space through a single antenna. . The duplexer modules 120 and 420 consist of one set of duplexers per sector, and the set of duplexers is equal to the number of beams formed by one multi-beam antenna.

The amplifiers 130 and 430 having the transmission amplifiers 131 and 431 and the reception amplifiers 132 and 432 amplify signals of respective beams to be transmitted or received. The number of transmit amplifiers 131, 431 and receive amplifiers 132, 432 is equal to the sum of the beams formed by all the multi-beam antennas 110, 410.

The reception measurement stages 110 and 450 provide a terminal through which a system administrator can externally measure a signal received by an antenna of the system.

The transceiver signal calibration module 210, 230, 460, 520 performs two functions. The first is to guarantee the same path gain (or path loss) with the existing base station, and the second is to ensure path equality between each path in the system. To this end, the transmit / receive signal correction module 210, 230, 460, 520 enables the gain and phase adjustment of each path. Gain and phase adjustment of each path can be implemented automatically or manually.

The outdoor light feed modules 221 and 471 and the indoor light feed modules 222 and 472 are configured in the system of the present invention to compensate for the disadvantages of the existing base station system. The first is an increase in transmit and receive link loss and receive noise figure due to the use of the RF cable, and the second is the installation problem and the cost of installing the RF cable. The optical feeding modules 220 and 470 can minimize signal attenuation by using optical fiber as a transmission medium, and the optical fiber material cost and installation cost are lower than that of an RF cable. In addition, the appearance of the base station pylon can ensure a beautiful appearance compared to the RF cable.

The optical power supply modules 220 and 470 perform photoelectric conversion of RF signals through optical fibers, and convert optical signals into RF signals. In addition, two optical transmission paths are provided per sector to support the delay diversity function of the transmission path, and each electrical length is implemented differently.

The call estimation module 180, 500 provides a criterion for allowing the multi-beam switching and synthesis / distribution system 140, 480 to adaptively synthesize / distribute the beams by using the transmitted and received signals. The call estimation module 180,500 converts the incoming RF signal into a digital signal, and then transmits the signal to the sector control module 190,510. The sector control modules 190 and 510 derive an optimal beam synthesis / distribution format using a beam control algorithm based on the digital signals received from the call estimation modules 180 and 500.

As described above, the call estimation modules 180 and 500 are located outdoors in FIG. 2 as an example of the present invention and indoors in FIG. 3 as another embodiment of the present invention. The call estimation module 180 and 500 considered two aspects in converting the digital signal. The first is transmission and reception path loss, and the second is coupling between multiple paths. The transmission / reception path loss corrects the degree of loss corresponding to the spatial position by the connection relationship in FIGS. 2 and 3. In addition, the coupling between the paths is determined by the coupling due to the radiation pattern of the multiple beams and the coupling between the internal components of the call estimation module 180 and 500, and corrects the combined coupling degree of the two points. The sector control module 190, 510 performs a correction function by a correction algorithm considering two aspects, and then performs a beam synthesis / distribution algorithm.

The repeater inlet and outlet ends 150 and 490 provide a signal transmission path and a matching function with a repeater connected to an existing base station when the system according to the present invention is applied to an existing base station. Since the repeater inlet and outlet ends 150 and 490 are connected and matched with the base station equipment located mostly in the repeater of the existing base station, it can be used more efficiently in the embodiment of the present invention according to FIGS. 4 and 5.                     

The beam switching and (system path) synthesis / distribution modules 140 and 480 are the core modules of the system and perform three important functions under the control of the sector control module.

The first is the adaptive beam synthesis / distribution function, which enables to configure various types of sectors by synthesizing and distributing the beams adaptively according to the call volume.

The second is a sector duplication function, which performs the independent sector configuration function of two heterogeneous base station systems using the same frequency or adjacent frequency resources and supporting different services. That is, each system of the heterogeneous system uses neighboring frequency resources, enables individual estimation of each frequency resource in the call estimation module, and a beam switching and synthesis / distribution module is configured for each heterogeneous system. Independent sector configuration is possible for each of two base station systems.

For example, when a voice-oriented CDMA (IS-95A / B), a CDMA-2000 1x system that simultaneously performs voice and data service, and an EV-DO system that will service only data, the sector duplication according to the present invention is used. The structure's multi-beam synthesis / distribution system enables the two sectors to be configured independently while sharing the RF transceiver and antennas of the two systems. This allows efficient and optimal cell engineering for different user call patterns of the two systems.

The third performs the angle diversity function of the transmit and receive paths. The control signals of the sector control modules 190 and 510 alternately or sequentially synthesize and distribute beams allocated to each sector and provide them to a diversity path.                     

The diversity path splitters 240 and 530 provide a dual path for an output signal of a frequency upconverter (UPC) which is a base station RF generator 300 and 600 to support delay diversity, which is a diversity scheme of a transmission path. Perform the function. As mentioned above, delay diversity is implemented through different lengths of light transmission paths between the indoor light feed modules 222 and 472 and the outdoor light feed modules 221 and 471.

The outdoor monitoring / control matching module (250,540) monitors and controls the status of system configuration modules and system enclosures mounted and installed outdoors, and reports the status to the indoor monitoring / control matching module (260,550), or It collects the status information from the indoor monitoring / control matching module (260,550) and control information of the parent base station (600,700).
