Abstract: In a mobile communication system, an error detection code or a quality frame indicator (e.g., CRC) is generated using selectively frame information, and at least one of a WCA identifier of another terminal, and a corresponding terminal identifier. And the terminal identifier can be implicitly transmitted to the receiver.

Abstract: A method and an apparatus for adjusting a power in a communication system are disclosed. The power control method includes selecting, in an active set, at least two base stations, estimating powers of respective reverse power control bits received from the at least two selected base stations, and transmitting, to the base stations, forward power control commands generated according to the estimated powers over power control groups, respectively.

Abstract: The present invention relates to a mobile communication system, and more particularly, to a method of adjusting a signal power in a variable data rate mode. Accordingly, the present invention includes steps of allocating a reference pilot signal level to each of a plurality of data rates supported by the system and adjusting the reference pilot signal level for a changed data rate based on an external control information and adjusting a power control threshold for secondly adjusting the reference pilot signal level corresponding to the reference pilot signal level.

Abstract: The present invention provides a method for providing multiple services and an apparatus for the same in a wireless packet data communication system. It guarantees various qualities of the services to a plurality of users by determining priorities of the mobile stations and an amount of resource allocated to each mobile station, and determining priorities of the multiple services and an amount of resource allocated to each service based on the resource allocated to each mobile station.

Abstract: A method of transmitting/receiving a packet using a hybrid automatic repeat request in the mobile communication system is disclosed. The packet data transmitting method includes transmitting at least one sub packet divided from plurality of encoded packets generated by repeating a bit stream that is made by encoding information desired to be transmitted with ⅕ rate turbo encoder, and transmission start point information of the sub packet through the sub packet identifier field on the accompanying control channel.

Abstract: Disclosed is a mobile communication systems, and more particularly a method of retransmitting data through a reverse link in a packet data, system, using ARQ (automatic repeat request) The present invention discloses a method for retransmitting data through a reverse link in Packet Data communication system using automatic repeat request(ARQ) adjusting data retransmission energy to be reduced at a predetermined ratio of one receiving energy for an initial data transmission to other receiving energy for a data retransmission.

Abstract: Method for configuring a transmission chain in a 3GPP2 system for supporting a flexible or variable data rate of an information bitstream in a process for mapping an information bitstream of a data rate on a physical layer, including the steps of (1) channel coding the information bitstreams with bit rates different from each other into turbo codes or convolution codes having a value inverse of 1/coding rate, and (2) repeating coded bitstream when the channel coded bitstream is smaller than a desired interleaving size, and puncturing the coded bitstream when the channel coded bitstream is greater than the desired interleaving size, for matching the channel coded bitstream to the interleaving size.

Abstract: A flexible data rate matching method in a 3GPP2 system is disclosed that supports flexible data rate repetition on a physical layer of synchronous cdma2000 in an interleaving process.

Abstract: A code combining soft handoff method is disclosed. A mobile terminal measures a strength of respective pilot signals received from a plurality of base stations. If the strength of the received pilot signal is higher than a given value, a base station controller allocates a new code pattern to the corresponding base station to additionally receive a signal from the base station. If the strength of the received pilot signal is lower than the specified value, it drops a signal of the corresponding base station. The mobile terminal and the base station change the code pattern of one of the signals from the two base stations into a code pattern different from the code pattern of the other signal.
