摘要： Two types of access probe messages are defined: a first when a mobile station has not yet been assigned a media access code index (MAC ID), and a second when a mobile station already has a MAC ID assigned by the base stations in the active set. Base stations can differentiate between the first and second types of access probes according to the scrambling sequence used. In the second type, while different MAC IDs are used by each of the mobile stations in the sector, they are all scrambled according to a similar scrambling sequence defined specifically for these second types of access probes. The rake receivers used in such networks are configured to repeat the rake finger processing after CP removal, DFT, de-channelizing, and IDFT, thereby reducing their complexity.

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.
