Abstract: PURPOSE: An apparatus and method for transmitting RPC(Reverse Power Control) channels in a mobile system supporting an HDR(High Data Rate) system is provided to solve a delay problem in applying RPC channels and to transmit two different RPC channels a slot. CONSTITUTION: An encoder(607) encodes and outputs data traffic channel data. A modulator(609) executes QPSK(Quadrature Phase Shift Keying) for the output of the encoder(607) and outputs I/Q signals. An interleaver(611) interleaves and outputs the output of the modulator(609). A puncture/repeat unit(613) punctures and repeats the output of the interleaver(611) according to a given pattern. A demultiplexer(615) demultiplexes and outputs the output of the puncture/repeat unit(613). An orthogonal spreader(617) multiplies the output of the demultiplexer(615) by a 16-long orthogonal code for orthogonal spreading. A repeater(623) repeats preamble data given times and outputs the data. A multiplier(625) executes orthogonal spreading by multiplying the output of the repeater(623) by a given orthogonal code and outputs a preamble signal. A multiplexer(619) executes time division multiplexing for the data traffic channel signal from the orthogonal spreader(617) and the preamble signal from the multiplier(625).

Abstract: PURPOSE: A forward link data service apparatus and method of a handoff terminal of a CDMA system are provided to improve a reception detection performance and heighten a data transfer rate by reducing an influence of an interference signal between sectors belonging to an active set through scheduling between sectors belonging to the active set. CONSTITUTION: When a terminal 'A' is selected(511), an alpha sector scheduler checks whether itself can transmits a packet by using a data received from an arbiter of a memory storing an idle sector(513). If the alpha sector scheduler recognizes that itself has not been stored through the arbiter of the memory storing the idle sectors, the alpha sector scheduler observes an active set of the terminal 'A' that itself is going to do a service(517). If there is a different sector in the active set of the terminal, the alpha sector scheduler requests an idle sector registration from the arbiter of the memory storing the idle sector. The memory arbiter updates the idle sector according to the idle sector registration request of the alpha sector scheduler(519). The memory arbiter informs each sector scheduler of the data on the updating of the idle sector. When the alpha sector scheduler receives the update data, the alpha sector scheduler transmits a packet data to the terminal 'A'(521). When the packet is completely transmitted, the arbiter of the idle sector memory deletes other sector values of the active set remembered before transmitting the packet stored in the idle sector region(523).

Abstract translation: 目的：提供CDMA系统的切换终端的前向链路数据业务装置和方法，以通过减少属于活动集的扇区之间的干扰信号对干扰信号的影响来提高接收检测性能并提高数据传输速率， 扇区属于活动集。 构成：当选择终端“A”（511）时，α扇区调度器通过使用从存储空闲扇区（513）的存储器的仲裁器接收到的数据来检查自身是否能够发送分组。 如果α扇区调度器识别出自身尚未通过存储空闲扇区的存储器的仲裁器存储，则α扇区调度器观察本身将要进行业务的终端“A”的活动集（517）。 如果在终端的活动集合中存在不同的扇区，则α扇区调度器从存储空闲扇区的存储器的仲裁器请求空闲扇区注册。 存储器仲裁器根据α扇区调度器（519）的空闲扇区注册请求更新空闲扇区。 存储器仲裁器向每个扇区调度器通知关于空闲扇区的更新的数据。 当α扇区调度器接收到更新数据时，α扇区调度器将分组数据发送到终端“A”（521）。 当分组被完全发送时，空闲扇区存储器的仲裁器在发送存储在空闲扇区区域（523）中的分组之前删除所记住的活动集的其他扇区值。

Abstract: PURPOSE: A method and apparatus for selectively requesting packet retransmission in a mobile system is provided to improve the throughput by increasing a channel adaptation speed in a link adaptation method and an ARQ(Automatic Repeat reQuest) method used in a mobile system. CONSTITUTION: A terminal searches a preamble every time a time slot is received and confirms whether a packet is received from a base station(S310). If a packet is received, the terminal checks the length of the preamble in order to confirm whether the received packet has a low data transfer rate(S320). In case that the packet has a low data transfer rate, the terminal measures a pilot C/I(Carrier to Interference ratio) value for a forward pilot channel or a forward pilot symbol corresponding to the time slot interval at which the present packet was transmitted(S330). The measured pilot C/I value is compared with the first threshold(S340). In case that the pilot C/I value is larger than the first threshold, the terminal decodes the present packet and checks an error through the CRC(Cyclic Redundancy Check)(S350). In case that there is no error(S360), the terminal transmits an ACK signal to the base station(S370).
