摘要： A method and apparatus for efficiently transmitting and receiving information about spreading codes used for a packet data-transmitting channel in a spread spectrum communication system. A BS determines Walsh codes for spreading a PDCH and transmits on a PDCCH an index of a last determined Walsh code. Also, if the determined Walsh codes cannot be fully represented by the use of the last Walsh code index only, the BS transmits a Walsh space bitmap indicating the availability of the Walsh codes individually on another PDCCH or a WAICH.

摘要： A method for generating a preamble sequence in an OFDM (Orthogonal Frequency Division Multiplexing) communication system that uses A sub-carriers in a frequency domain and uses N Tx (Transmission) antennas, includes the steps of: generating N sequences, each having a length of ‘B/N’, by dividing B sub-carriers from among the A sub-carriers by the ‘N’ indicative of the number of the Tx antennas; and mapping, for each of the N sequences, individual components of the sequence to the B/N sub-carriers from among the A sub-carriers on a one by one basis in order to assign the components of the sequence to the B/N sub-carriers, and assigning null data to remaining sub-carriers other than the B/N sub-carriers from among the A-sub-carriers, such that a preamble sequence of a corresponding Tx antenna is generated.

摘要： An apparatus and method for transmitting/receiving a PDCCH (Packet Data Control Channel) for efficient packet data transmission in a communication system supporting packet data service. To allow both TDM-transmission and TDM/CDM-transmission of packet data, PDCCHs having different control information are transmitted. A 1PDCCH and a 2PDCCH are selectively transmitted according to the channel environments of users to thereby minimize the transmission power of the 1PDCCH and the 2PDCCH. A PDCCH receiver receives the 1PDCCH and the 2PDCCH using Walsh functions assigned to them, demodulates them, and checks errors in them, thereby obtaining control information about packet data to be received.

摘要： There is provided an encoding apparatus and method in a CDMA communication system. To encode input information of a k-bit sequence and generate a codeword with length N>(2k−1), an encoder encodes the input information using an (r, k) simplex code and generates a sequence of code symbols of length r (r=2k−1), a repeater repeats the sequence of code symbols t times ( t = ⌊ N r ⌋ + 1 ) , and a puncturer performs puncturing A times (A=rt−N) on the t repeated code symbol sequences so that the resulting codes have length N. The punctured symbols are distributed uniformly across the repeated code symbol sequences or confined to the tth repeated code symbol sequence.

摘要： Disclosed is provided a method for switching an operation mode from a non-USTS to a USTS mode in a Node B capable of communicating with a UE in both the non-USTS mode and the USTS mode. The Node B calculates a difference value between a start point of a downlink dedicated channel frame in a downlink dedicated channel transmitted to the UE in the non-USTS mode and a start point of an uplink dedicated channel frame in an uplink dedicated channel received from the UE. The Node B determines a first control value for controlling the start point of the uplink dedicated channel frame in the uplink dedicated channel by comparing the difference value with a given reference value, and also determines a second control value such that the second control value for the start point of the downlink dedicated channel frame in the downlink dedicated channel becomes a multiple of a given number of chips. Further, the Node B informs the UE of the determined first and second control values, and then transmits a downlink dedicated channel signal such that the start point of the downlink dedicated channel frame becomes a start point determined based on the second control value.

摘要： A base station PDCCH (Packet Data Control Channel) apparatus for scrambling transmission packet data to prevent other terminals from recognizing the transmission packet data in a base station including a packet data channel device for transmitting packet data to a terminal and a packet data control channel device for transmitting control information needed for demodulation of the packet data to the terminal. In the apparatus, an encoder encodes the control information and generates a coded control information stream comprised of a stream of a plurality of bits. A scrambler generates a scrambling sequence using unique information known to only the terminal and the base station, and scrambles the coded control information stream with the scrambling sequence.
