    摘要: A reverse transmission controlling method in a mobile communication system, after receiving forward information, commanding the increase or decrease of the reverse data rate received on a forward control channel from a base station, a mobile station determines whether the previous rate increase available information transmitted to the base station on a reverse control channel before reception of the forward information indicates that a reverse data rate increase is available, if the forward information commands a reverse data rate increase. The mobile station increases the current reverse data rate to a data rate equal to or less than a maximum reverse data rate if the rate increase available information indicates that the reverse data rate increase is available, and transmits reverse data at the increased reverse data rate.

    摘要: A method and apparatus for generating a preamble sequence in an orthogonal frequency division multiplexing (OFDM) communication system having m subcarriers in a frequency domain. The method comprises generating a preamble sequence of length n that is mapped to n subcarriers on a one-to-one basis, where n is less than m; and assigning components constituting the preamble sequence to the n subcarriers among the m subcarriers on a one-to-one mapping basis, assigning null data to the remaining subcarriers excluding the n subcarriers from the m subcarriers, and then IFFT (Inverse Fast Fourier Transform)-transforming the assigned result into time-domain data.

    摘要: A method and apparatus for providing a service based on multiple data rates using scalability of a multimedia CODEC in an asynchronous code division multiple access (CDMA) communication system, which provides a multimedia broadcast and multicast service (MBMS). An entire cell area is divided into a first area and a second area. Specific data is separated into first data and second data. The first data is transmitted to the first area, and the second data is transmitted to the second area. A first electric power controller controls electric power for the first data. A second electric power controller controls electric power for the second data. A user equipment (UE) located in the second area receives the first data and the second data. The UE located in the second area combines the first data and the second data, thereby generating one data item.

    摘要: Provided are an apparatus and a method for providing a concurrent data service to an Mobile Station (MS) through a plurality of heterogeneous networks. In a method for providing a data service to an MS through different wireless networks, the MS measures channel qualities of at least one accessible wireless network (913) and reports the measured channel qualities to an Internet Protocol (IP) packet controller (914). The IP packet controller selects wireless networks for data transmission on the basis of the reported channel qualities (918), distributes data destined for the MS (919), and transmits the distributed data to the selected wireless networks (920). The selected wireless networks receive the data from the IP packet controller and transmit the received data to the MS (922). The MS combines and interprets the data received from the selected wireless networks (923,924). Accordingly, it is possible to provide a seamless data service to the MS in service environments with a mixture of different wireless communication systems.

    摘要: A mobile communication system receives a despread signal of a reception signal, and performs a control operation such that a weight for generating a reception beam is calculated using a first technique if a difference between an error value at a current time and an error value at a previous time is greater than an absolute value of a first threshold or the error value at the current time is greater than or equal to a second threshold, and performs a control operation such that the weight is calculated using a second technique if the different between the error value at the current time and the error value at the previous time is less than or equal to the absolute value of the first threshold and the error value at the current time is less than the second threshold.
