Abstract: PURPOSE: A method for transmitting and receiving OVSF(Orthogonal Variable Spreading Factor) code information assigned to user data in a high speed downlink packet access communication system is provided to transmit and receive information about all OVSF codes capable of being assigned to the user data by using only separate logical identifiers. CONSTITUTION: A scheduler(502) determines a user data transmission time and an OVSF code to be used in the transmission of user data of a corresponding UE(User Equipment) with reference to the user data quantity or the user data type of other UEs. The scheduler(502) retrieves an OVSF code information table storing unit(509), detects a logical identifier corresponding to the determined OVSF code used in the transmission of the user data, and transmits the detected logical identifier to a control information generator(506). The control information generator(506) converts MCS(Modulation and Coding Scheme) level information and the logical identifier into a format suitable for a wireless channel. A channel encoder(507) performs a channel coding of control information outputted from the control information generator(506), and outputs coded control information to a control data transmitting unit(508). The control data transmitting unit(508) modulates and channelizes control information outputted from the channel encoder(507), and transmits control information to the corresponding UE.
