Methods and apparatuses for fast power control of signals transmitted on a multiple access channel

一种方法，用于控制在多个M多址联接信道上从多个移动站(1300)中的一个或多个移动站到基站(1400)的信号发送。从基站(1400)到一个或多个移动站(1300)发送从多个功率控制位形成的功率控制信息分组。在功率控制信息分组中的每个功率控制位具有一个位置，使所述位置映射到所选择的接入信道和在所选择的接入信道内的时间偏移。在第一移动站(1300)处接收功率控制信息分组。然后在第一接入信道上和与第一接入信道相关联的第一时间偏移处把消息从第一移动站(1300)发送到基站(1400)。在根据功率控制信息分组中的第一功率控制位确定的功率电平处从第一移动站(1300)发送消息。使第一功率控制位位于功率控制信息分组中的第一位置，所述第一位置是映射到第一接入信道和第一时间偏移的。 A method and apparatus for controlling the transmission of signals from one or more of a plurality of mobile stations (1300) to a base station (1400) on a plurality of M multiple access channels. A power control information packet formed from a plurality of power control bits is transmitted from the base station (1400) to the one or more mobile stations (1300). Each of the power control bits in the power control information packet has a position that is mapped to a selected access channel and to a time offset within the selected access channel. The power control information packet is received at a first mobile station (1300). A message is then transmitted from the first mobile station (1300) to the base station (1400) on a first access channel and at a first time offset associated with the first access channel. The message is transmitted from the first mobile station (1300) at a power level determined in response to a first power control bit in the power control information packet. The first power control bit is located in a first position in the power control information packet, the first position being mapped to the first access channel and the first time offset.
