    摘要: Power control in a spread spectrum communication system takes place by determining a speed of a remote unit (405) and assigning as a power-control threshold a target threshold based on the determined speed (410). An instantaneous threshold value is created (415) based on frame-quality information and the target threshold. An energy of a power-control group transmitted (430) from a remote unit is compared to the instantaneous threshold value and a power-adjustment command is determined. The power-adjustment command is transmitted to the remote unit instructing the remote unit to adjust its power accordingly.

    摘要: A method and apparatus is provided for use in a radio communication system having a first and second base site communication unit (116, 118) operatively coupled to a first and second transcoder (106, 108), respectively. This system also includes a mobile communication unit which is requesting to enter a linked-communication mode with the first and second base site units. In order to perform a linked-communication, a transcoder-base site interface link is established between the second base site and the second transcoder. In addition, the second transcoder is configured to operate in a bypass mode such that it relays information within the transcoder-base site interface link through a communication across regional entity (CARE)-Link in conjunction with a CARE-Control-Link between the first and second transcoder. Finally, the first transcoder is configured to operate in linked-communication mode by relaying information within the CARE-Link which is controlled by the CARE-Control-Link.

    摘要: A method for updating power control at a base transceiver station in a communication system (100) is provided. A base transceiver station (104) transmits a signal frame (201). A mobile station (102) receives the signal frame (203). The mobile station (102) determines whether the signal frame was accurately received (205) and sets a metric bit in a quality metric (207, 209). The metric bit indicates whether the signal frame was received correctly by the mobile station (102). The mobile station (102) transmits the quality metric (211), which is received by the base transceiver station (104). It is then determined whether to update power control, the determination based at least in part upon the quality metric.
