It relates to a networking method.

Recently, with the development of communication environment, IMT-2000 (International Mobile Telecommunications-2000) communication system, a third generation communication system, has emerged. Among the wireless transmission technologies of the IMT-2000 communication system, code division multiple access (CDMA) Code Division MultipleAccess technology is a method of spreading spectrum by second-modulating a signal with a spreading code much faster than an information signal, so that all terminals can access the same frequency at the same time and identify the terminals by the difference of spreading codes. .

The duplex scheme of CDMA includes a frequency division duplex (FDD) scheme and a time division duplex (TDD) scheme. The FDD method is a communication method in which a mobile station and a base station, which are terminal apparatuses, allocate and separate different frequencies to Tx and Rx signals when transmitting and receiving signals. On the other hand, the TDD method is a communication method in which a mobile station and a base station allocate the same frequency to the Tx signal and the Rx signal when the mobile station and the base station transmit / receive a signal, and separate them by using different times. That is, one frequency channel is divided into time slot units,

A method of allocating a predetermined number of slots to a forward link between a base station and a mobile station, and assigning the remaining slots to a reverse link between a mobile station and a base station to enable bidirectional communication in one frequency channel. Accordingly, the TDD scheme is superior in terms of frequency efficiency compared to the FDD scheme. However, the TDD scheme and the FDD scheme coexist in a current communication environment.

Hereinafter, the operation of the remote M / W module 180 will be described briefly as follows.

The IF signal input from the remote RF module 120 is applied to the filter unit 30. If the terminal apparatus 2 transmits an FDD signal, the remote M / W module 180 receives the FDD Tx signal from the remote RF module 120 and the signal passes through the first filter 130 to transmit the signal. In step 140, the M / W signal is processed and then transmitted through the antenna 170. This can be said to be processed according to the general microwave relay method. If the terminal device 2 transmits a TDD signal, the remote M / W module 180 receives the TDD Tx signal and the TDD switching signal from the donor RF module 120 and switches according to the TDD switching signal. The TDD Tx signal from the remote RF module 120 passes through the third filter 133 and is processed as an M / W signal by the transmission processor 140 through the switching unit 160 to be transmitted through the antenna 170. will be. This can be said to be processed in connection with the general microwave relay method.

In addition, the M / W signal received through the antenna 170 is processed by the reception processor 150 as an IF signal. If the base station 1 transmits an FDD signal, the TDD Rx signal output from the reception processor 150 passes through the second filter 132 and is output to the remote RF module 120. This can be said to be processed according to the general microwave relay method. If the base station 1 transmits a signal of the TDD method, the switching unit 160 of the remote M / W module 180 switches according to the TDD switching signal to output an output terminal of the reception processor 150 and the third filter 133. Since the TDD Rx signal output from the reception processor 150 passes through the third filter 133, the remote RF module 120 is output. This can be said to be processed in connection with the general microwave relay method.

As described above, the FDD / TDD integrated microwave module, that is, the donor M / W module 80 and the remote M / W module 180, according to the present invention, are used for FDD transmission / reception and TDD transmission / reception. Rather than implementing separate paths, each of the transmitters 40 and 140 and the receivers 50 and 150 is provided so that the signal transmission / reception of the FDD / TDD method between the base station 1 and the terminal device 2 can be achieved. It can support all of them. Accordingly, the present invention can effectively support both FDD and TDD schemes while reducing the cost of the relay network.

Herein, step S30 will be described in detail. As described above, the IF signal input from the donor RF module 20 is applied to the filter unit 30 for filtering the FDD frequency band and the TDD frequency band, respectively ( S30). If the base station 1 transmits a signal of the FDD method, the IF signal, that is, the FDD Tx signal passes through the first filter 31 of the filter unit 30, and if the base station 1 transmits a signal of the TDD method, IF The signal, that is, the TDD Tx signal, passes through the third filter 33. Accordingly, it is determined whether the IF signal of the TDD type passes through the filter unit 30 (S34), and whether the IF signal of the FDD type passes through the filter unit 30 (S36).

Accordingly, as a result of determination, if the IF signal of the FDD method passes through the filter unit 30, the FDD Tx signal passed through is processed as an M / W signal by the transmission processing unit 40 and then transmitted through the antenna 70, and the reverse link In this case, the M / W signal received through the antenna 70 is processed as an IF signal by the reception processor 50, passes through the second filter 32, and is output to the donor RF module 20 (S40).

As a result of the determination in step S34, when the TDD type IF signal passes through the filter unit 30, the passed TDD Tx signal is input to the transmission processing unit 40 according to the TDD switching signal, processed into an M / W signal, and then antenna 70. M / W signal transmitted through the antenna 70 and received through the antenna 70 in the reverse link is processed as an IF signal by the reception processor 50 and passes through the third filter 33 according to the TDD switching signal. Output to the module 20 (S50).

The method of claim 13, In step c), Inputting the IF signal output from the filter unit to the transmission processing unit for processing an IF signal into a microwave signal for output to the antenna, and from the reception processing unit for processing the microwave signal received through the antenna as an IF signal FDD / TDD integrated microwave relay networking method characterized by applying the output IF signal to the filter unit. The method of claim 14, In step d), When the TDD type IF signal is input through the filter unit, the TDD type IF signal path is switched to either the transmitting processor or the receiving processor according to the TDD switching signal. Relay networking method.
