摘要： A location of an access terminal is estimated based on uplink signals that a plurality of femto cells receive from the access terminal. The transmit power of the access terminal may be adjusted in some cases to facilitate the reception of signals at the femto cells during a location determination operation. In some embodiments, a location of an access terminal is estimated based on relative path loss values derived from the signals received by the femto cells.

摘要： Methods and apparatuses are provided for performing power control for a femto node deployed in a wireless network that include adjusting a transmission parameter of the femto node based on one or more signal energy parameters, such as a received signal strength indicator (RSSI). A comparison between the signal energy, a noise floor, and a threshold signal energy can be determined, and a transmission parameter of the femto node is accordingly adjusted based on the comparison.

摘要： Methods and apparatuses are provided that include deploying a femto node in a wireless network. The femto node can measure received signal quality upon initialization in a wireless network and/or according to a timing. The femto node can determine whether to communicate in the wireless network based on comparing the received signal quality to a threshold signal quality. The timing can be determined based on various factors to ensure fairness among femto nodes initializing in the wireless network. A centralized entity can be used to determine the timing and/or whether a femto node should communicate.

摘要： A power calibration scheme adjusts power levels of network of femtocells based on macro signals seen at different points in and around a coverage area and based on the mutual positions of the femtocells (e.g., based on femtocell signals seen at these points). The power calibration scheme thus facilitates a good balance between providing a desired level of coverage and mitigation of interference to nearby macrocells and femtocells.

摘要： Methods and apparatuses are provided for performing power control for a femto node deployed in a wireless network that include adjusting a transmission parameter of the femto node based on one or more radio frequency (RF) environment parameters. An RF environment parameter can be determined for a femto node related to a location in a coverage area. A different RF environment parameter related to other femto nodes at the location in the coverage area can be received from one or more devices, a network listening module, etc. A transmission parameter of the femto node, such as a transmit power, can be adjusted based on the RF environment parameter and the different RF environment parameter.
