    摘要: Disclosed are a forward multiple scrambling code generating method and apparatus in a communication system. Each base station uses primary scrambling codes and an associated one of secondary scrambling code sets, each consisting of a plurality of secondary scrambling codes. When an n-th one of the primary scrambling codes is to be generated, an initial value of the scrambling code generator is set with a binary value of “n,” so that a desired primary scrambling code is generated using the initial value. When an n-th one of the secondary scrambling codes in an m-th one of the secondary scrambling code sets is to be generated, an initial value of the scrambling code generator is set with a value obtained by shifting the n-th primary scrambling code by m times, thereby generating a desired secondary scrambling code. Since the primary and secondary scrambling codes are simultaneously generated using a single code generator, the manufacturing costs and load are reduced, and the size and power consumption of user elements are reduced. It is also possible to reduce the number of calculations required to set the initial values required for the generation of scrambling codes.

    摘要: A method of transmitting packet data to a receiver in a communication system using a Hybrid ARQ technique is disclosed. In accordance with one illustrative embodiment of the present invention, an index representative of how much the first packet being transmitted such as a signal-to-noise (Eb/No) ratio is compared to a predetermined threshold value when an error is occurred during the step of decoding the packet. If the index is greater than or equal to the threshold value, the first packet transmitted is stored in a buffer and a receiver requests to transmit a second additional packet encoded with a lower code rate. On the other hand, if the index is less than the threshold value, the receiver requests to re-transmit the first packet encoded with the same code rate.

    摘要: Disclosed is a method of transmitting/receiving a broadcast message in a mobile communication system enabling to transmit a broadcast message including a video and the like. The present invention proposes an additional broadcast channel so as to transmit a broadcast message such as a video to a mobile station. Moreover, the present invention proposes a method of enabling a mobile station to confirm a summary or channel information so as to demand a broadcast message selectively by previously transmitting information, which is called a data burst summary message or a data burst message by the present invention, about the summary of the broadcast message or a channel through which the broadcast message will be transmitted prior to transmitting the broadcast message having large traffic volume.
