Problems solved by technology

In this case, if the transmit antennas have different transmit capabilities, and as a result one particular transmit antenna has a small transmit capability, some errors are generated at similar rates in the case of systematic bits and parity bits, which may affect the entire system performance
That is, the system performance may be more severely degraded than in the case where errors occur only in parity bits

[0074] In the first embodiment of the present invention, the transmitter determines the transmission status of each transmission antenna in the transmission antenna array and transmits data according to the transmission status. The receiver determines the reception status of each reception antenna in the reception antenna array and receives data according to the reception status.

[0075] For the above operations, the mobile communication system is configured and operated as follows.

[0076] (1) Measure the transmission state of each transmission antenna in the transmission antenna array and generate control information corresponding to the transmission state.

[0077] (2) The respective transmission antennas are classified into data groups according to the priority and the respective data groups are assigned to the transmission antennas according to the control information.

[0078] (3) Using the received signal to measure the state of each downlink channel and recover the ...

[0112] In the third embodiment of the present invention, each UE determines the status of the downlink channel received through the receiving antennas of the antenna array and feeds back the transmission status information to the BS, so that the transmission status information is under the same control of Node B and MS .

[0113] Figure 13 is a block diagram of a transmitter of a mobile communication system according to a third embodiment of the present invention. refer to Figure 13 , the channel estimator and transmit antenna allocator 308 receives feedback information H about the transmit states of the transmit antennas 312, 314, 316, and 318 of the transmit antenna array from each UE. The feedback information receiver 310 feeds back the sending status information H to the controller 306 . The controller 306 controls the transmit antenna allocator 308 to properly distribute the data groups to the transmit antennas 312 , 314 , 316 and 318 according to the transmission st...

[0130] In the fourth embodiment of the present invention, both the transmitter and the receiver determine the state of the downlink channel established corresponding to each transmit antenna in the transmit antenna array. Thus, it is possible to send transmission status information from the sender to the receiver and vice versa. In this specification, the fourth embodiment is a combination of the second and third embodiments.

[0131] Figure 15 is a block diagram of a transmitter in a mobile communication system according to a fourth embodiment of the present invention. Such as Figure 15 As shown, the transmitter includes two transmission status information transmitters 372 as in the second embodiment and the same feedback information receiver 370 as in the third embodiment, therefore, Node B can send / receive transmission status information to / from each UE.

[0132] refer to Figure 15 , the Node B 10 divides the transmitted data into multiple data groups according to...

Abstract

A data transmitting / receiving apparatus and method using an antenna array in a mobile communication system. A Node B measures a transmission status of each transmission antenna, classifies transmission data according to priority, and transmits to a UE high-priority data through a transmission antenna at a relatively good transmission status and low-priority data through a transmission antenna at a relatively poor transmission status.

Description

[0001] This application claims priority from Application No. 2001-49831, entitled "Apparatus and method for transmitting and receiving data using an antenna array in a mobile communication system" filed with the Korean Industrial Property Office on Aug. 18, 2001 , the contents of which are incorporated herein by reference. technical field [0002] The present invention generally relates to a data transmission / reception apparatus and method in a mobile communication system including an antenna array, and more particularly to a data transmission / reception apparatus and method in a mobile communication system with an antenna array having antenna diversity. Background technique [0003] In general, radio channels have low reliability relative to wired channels due to multipath fading, shadowing, propagation attenuation, time-varying noise, and interference. This is an obstacle to increasing data rates and therefore many techniques have been proposed to overcome the limitations o...
