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.

An RNC determines parameters available for measurement of a synchronization signal and second Node B information from a second Node B, transmits the determined parameters to a first Node B during radio link setup and to a UE during radio bearer setup, and transmits parameter selection information to the first Node B and the UE, if it is recognized that measurement of the synchronization signal and the second Node B information is necessary. The first Node B changes a position of a downlink time period over which a downlink channel is transmitted from the first Node B to the UE and a position of an uplink time period over which an uplink channel is transmitted from the UE to the first Node B, according to parameters selected from the parameters. The UE receives the synchronization signal and the second Node B information in the remaining time periods except the changed downlink time period and the changed uplink time period among the plurality of time periods.

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.

A device and method for configuring an UL-DPCCH. One or more UL-DPCCHs, especially a UL-DPCCH for supporting HSDPA, are constructed in code division multiplexing and transmitted according to the characteristics of control information. The UL-DPCCH of the present invention that delivers various kinds of control information can be configured flexibly and operate in compatibility with a conventional asynchronous mobile communication system.
摘要:
In a mobile communication system, if a UE enters a SHO (Soft Handover) region, the UE determines weight information for a DPCH and a PDSCH depending on DPCH signals and PDSCH signals received from Node Bs, and transmits the determined weight information to the Node Bs. The Node Bs then determine weights of the DPCH signals and the PDSCH signals to be transmitted to the UE depending on the feedback information received from the UE, and transmit the determined weights to the UE along with the DPCH signals and the PDSCH signals, respectively.
摘要:
Disclosed is a method and apparatus for efficiently transmitting/receiving transmission power status information (TPS) and buffer state information (BO) of a user equipment (UE). Under the assumption that an enhanced uplink dedicated transport channel (EUDCH) is used for an uplink data transmission in an asynchronous code division multiple access (CDMA) system, a scheduler of a Node B performs a scheduling operation such as transmission timing of EUDCH packet data, data rate assignment, and the like. The scheduler receives the EUDCH packet data BO, TPS, and the like, and efficiently performs processes of start/continuation/end of the TPS transmission.

摘要:
Methods and apparatus are provided for communication between a User Equipment (UE) and a Node B in a communication system. The UE generates a Media Access Control-Protocol Data Unit (MAC-PDU) including scheduling information having information representing an amount of packet data to be transmitted. The MAC-PDU including the scheduling information is transmitted to the Node B. The information representing the amount of packet data exists per priority queue.
