    • A transmit power control technique within a wireless communication system includes adjusting a transmit power used by a picocell base station unit based upon a position of the picocell within a macrocell. When a picocell base station unit is located relatively close to a macrocell base station or center of the macrocell, the transmit power of the picocell base station unit is increased to avoid downlink interference from the macrocell base station for mobile stations communicating within the picocell. When a picocell base station unit is located relatively close to an edge of a macrocell, the transmit power of the picocell base station is decreased to avoid interference caused by the picocell base station unit for mobile stations communicating within the macrocell in the vicinity of the picocell. In a disclosed example determined downlink interference levels provide an indication of the position of the picocell within the macrocell and provide an indication of how to automatically adjust the transmit power of the picocell base station unit.
    • 无线通信系统内的发射功率控制技术包括:基于微蜂窝小区中的位置来调整微微小区基站单元使用的发射功率。 当微微小区基站单元相对靠近宏小区基站或宏小区的中心位置时,增加微微小区基站单元的发射功率,以避免来自宏小区基站的用于在微微小区内通信的移动站的下行干扰。 当微微小区基站单元位于相对靠近宏小区的边缘时,微微小区基站的发射功率减小,以避免由微微小区基站单元对微微小区附近的宏小区内通信的移动站造成的干扰 。 在公开的示例中,确定的下行链路干扰电平提供微蜂窝在宏小区内的位置的指示,并提供如何自动调整微微小区基站单元的发射功率的指示。
