摘要： A method is described for transmitting data from a mobile station to a wireless network, as is a wireless communications system that operates in accordance with the method. The method includes (a) requesting permission to transmit data using an access channel; (b) in response to receiving a permission message from the wireless network, transmitting the data from the mobile station to the wireless network over a control channel using a modulation and channel coding scheme determined in the wireless network, and communicated to mobile station in the permission message; and (c) in response to receiving the transmitted data at the wireless network, soft combining the received data with previously received data, if any, until a desired decoding result is achieved, and transmitting an acknowledgment of data reception to the mobile station. The steps of transmitting and receiving preferably use a code division, multiple access technique.

摘要： Near-far effect fading is counteracted by changing the spreading factor used for uplink channel spreading. The determination that a radio uplink channel power fade exists can be made in either the radio access network or the mobile station.

摘要： A method and apparatus for power control on a first channel that is shared by multiple mobile stations transmitting to base stations in a telecommunication system. An initial mobile station transmission power level is set on the first channel that is shared in the random access mode. The transmission power level may be determined based on a desired performance level of the first channel. The method and system may be efficiently applied on a channel that carries a transmission in one or more bursts, with each burst including the same or a varying number of frames of varying sizes. The method and apparatus utilizes a second channel that is shared by multiple mobile stations for transmitting the power control signaling from the base stations to the mobile stations.
