    摘要: Disclosed is a method and apparatus for providing uplink packet data services through an E-DCH in an asynchronous WCDMA system. A transport block size (TBS) for transmitting uplink transport channel data is determined. A combination of a spreading factor and a modulation scheme for uplink channel data transmission, corresponding to the determined TBS, is selected according to transmittable physical channel data bit sizes and puncturing limit values. The TBS is transmitted by incorporating it into control information of the uplink transport channel data. The modulation scheme and spreading factor combination is determined based on a physical channel data bit size that maximizes transmission efficiency and minimizes the number of punctured bits, without requiring an additional physical channel in transmitting the uplink data having the TBS. This method maximizes uplink transmission efficiency to save transmission resources and reduces signaling overhead required to transmit E-DCH control information.

    摘要: A method is provided for transmitting a control channel for resource allocation to a terminal by a base station in an Orthogonal Frequency Division Multiple Access (OFDMA) wireless communication system. An additional resource allocation indicator is set indicating whether the number of consecutive resource block sets allocated to a terminal is greater than one. A reference control channel is generated including reference resource allocation information for a first consecutive resource block set and the set additional resource allocation indicator. An additional control channel using additional resource allocation information is generated, when there are one or more additional consecutive resource block sets. At least one of the generated reference control channel and the generated additional control channels is encoded before transmission.

    摘要: An encoding method and apparatus for a DCH (Dedicated Channel) encoder and a DSCH (Downlink Shared Channel) encoder in a transmitter for a mobile communication system including the DCH encoder for encoding k bits among 10 input TFCI (Transport Format Combination Indicator) bits and the DSCH encoder for encoding remaining (10-k) bits among the input TFCI bits. The method comprises generating, by the DCH encoder, a first coded bit stream by encoding the k input bits into 32 bits, and outputting a (3k+1)-bit stream by puncturing the first coded bit stream according to a specific mask pattern corresponding to the k value; and generating, by the DSCH encoder, a second coded bit stream by encoding the (10-k) input bits into 32 bits, and outputting a {3*(10-k)+1}-bit stream by puncturing the second coded bit stream according to a specific mask pattern corresponding to the (10-k) value.

    摘要: A method and apparatus for efficiently controlling uplink traffic rates, performing scheduling accompanied by fast rate ramping, and transmitting uplink rate assignment information in an asynchronous WCDMA communication system. A Node B determines an allowed current rate for an uplink channel. If the difference between the current rate and the previous rate is two or more levels, the Node B transmits a rate indication indicating the current rate. If the difference between the current rate and the previous rate is zero or one level, the Node B transmits a rate up/down indicating a rate change from the previous rate to the current rate. Also the Node B may transmit the rate indication instead of the rate up/down, periodically or in an event-triggered manner.

    摘要: Disclosed is a method for transmitting a dedicated physical data channel signal over a dedicated physical data channel in the absence of transmission data to be transmitted over the dedicated physical data channel in order to properly maintain a target SIR (Signal-to-Interference Ratio) when there exists new transmission data after the absence of the transmission data in a CDMA (Code Division Multiple Access) mobile communication system. The method comprises generating a dummy bit generation request signal in the absence of the transmission data; and upon receipt of the dummy bit generation request signal, generating a dummy bit stream, and transmitting a dedicated physical data channel signal created by attaching the CRC bit stream to the dummy bit stream.
