    摘要： A method for transmitting data from a radio network subsystem to user equipment in a mobile telephone system, a radio network subsystem and user equipment. In the method, the radio network subsystem transmits a dedicated control channel to the user equipment and a dedicated traffic channel of variable data transmission rate to the user equipment. During transmission, the radio network subsystem spreads each channel with a spreading code, and the spreading code used to spread the traffic channel is changed according to the required data transmission rate. According to the invention, each control channel frame indicates the spreading code with which the corresponding traffic channel is spread when transmitted.

    摘要： System and methods for improved uplink signal detection where when a mobile device detects signaling indicating the presence of a packet for that mobile device from a network node, the mobile device may transmit one or more NACKs in a sub-frame before the one in which the mobile device would transmit the normal ACK/NACK for the packet. Additionally, the mobile device may transmit one or more NACKs in the sub-frame immediately following the normal ACK/NACK for a packet (unless a packet was transmitted in the immediately following sub-frame and successfully decoded by the mobile device, in which case an ACK would obviously be transmitted). Therefore, extra uplink (UL) interference is eliminated. Moreover, the amount that a network node must offset its ACK/NACK decision threshold is significantly reduced. This results in a reduction of required ACK power by a mobile device.

    摘要： A base station (Node B) 12 provides information to a Radio Network Controller (RNC) 16 on how well User Equipment (UE) 14 subject to Node B scheduling is served for an Enhanced Dedicated Uplink Channel (E-DCH). This may be done for instance by the Node B measuring or estimating 22 the requested data rate per UE/cell, and communicating 24 the measured or estimated information to the RNC for enabling the RNC to perform Radio Resource Management (RRM). The RNC is thereby enabled to know the quality of the E-DCH transmission service per UE/cell. In addition to helping Admission Control and Load Control, it also enables the RNC to reconfigure the transport format combination set (TFCS) for E-DCH with more accurate timing. The UE and the Node B exchange information such as rate request/grant or UE Buffer and Transmit Power Status/Scheduling Assignment.

    摘要： A wireless communications network has a plurality of terminals and at least one base station which transmits data to each one of said plurality of terminals on a wireless downlink and receives data from each one of said plurality of terminals on a wireless uplink. One of the terminals sends a rate request to the base station. The rate request requests that the data rate on the wireless uplink for the terminal be changed. In response to the rate request, the base station sends a rate grant to the terminal. The rate grant indicates whether or not the terminal may change the data rate on the wireless uplink.
