Embodiment Construction
[0047] figure 1 It is a schematic flowchart of a wireless network access method in the prior art. First, in step 101, the mobile station synchronizes with the downlink channel of the base station, and sends a ranging request message to the base station using dedicated resources. Next, in step 102, the base station sends a ranging response message to the mobile station. Then, if figure 1 As shown, the access process ends. Although figure 1 Exemplary only, but it can be easily seen that figure 1 The wireless network access method shown does not involve relay stations. In some application situations, a small number of shadowing holes exist in cells such as base stations, or base stations are deployed in low-density areas, and at this time mobile stations cannot communicate normally. In addition, when the mobile station is located at the edge of the cell or in a deep fading area, the mobile station should adjust the transmit power to the maximum value, at this time, the batt...
