摘要:
An apparatus and method for transmitting and receiving wireless packet data are provided. In a wireless packet data transmitter for transmitting to a wireless packet data receiver data packet on a transport channel and control information for supporting the transport channel on a control channel in a wireless packet data communications system, a padding bit eliminator eliminates optional padding bits of a variable size from a transport block for data packet transmission. A transport channel encoder for transport channel-encodes the transport block without the padding bits and transmits the encoded transport block on the transport channel. A control channel encoder control channel-encodes the control information including a padding bit number indicator indicating the number of the eliminated padding bits and transmits the encoded control information on the control channel.

High Speed Shared Control CHannel (HS-SCCH) communicating apparatus and method in Wideband Code Division Multiple Access (WCDMA) wireless communication system are provided. A receiver of a mobile communication terminal in the WCDMA communication system, which includes a speed estimator for determining a transmission interval of a Channel Quality Indicator (CQI) by measuring a channel change speed of a downlink from the signal fed from the communication module, shortening the CQI transmission interval when channel conditions changes quickly, and lengthening the CQI transmission interval when the channel conditions change slowly; and a decoder for interpreting the signal and providing the signal to an upper layer.

An apparatus and a method for scanning a network in a mobile communication terminal are provided. The method for scanning a network in a mobile communication terminal includes to configure a PLMN list based on a Subscriber Identification Module (SIM) card, to store scanned frequency information and corresponding PLMN information into a database by a previous scanning result, to compare the database with the PLMN list and to perform a scanning corresponding to frequency bandwidths included in the database or performing a scanning entire frequency bandwidths according to a result of comparison.

An apparatus and method for service acquisition in a multimode system are provided. The method includes attempting a first location registration to a mobile communication system having a highest priority according to a priority order and, attempting a next location registration to a mobile communication system of a next priority order from the priority order, if the first location registration is rejected for a specific cause.
