摘要： A cell reselection parameter is transmitted on one carrier frequency for a defined period of time to cause access terminals operating on that carrier frequency to more aggressively search for access points on at least one other carrier frequency. For example, a femto cell operating on one carrier frequency may transmit a broadcast channel including a cell reselection parameter such as Sintersearch on another carrier frequency that is used by a macro cell. Here, the value of the cell reselection parameter (e.g., Sintersearch) is chosen so that the access terminals will more aggressively conduct inter-frequency searches. In addition, the cell reselection parameter is transmitted for a period of time that ensures that a nearby access terminal will receive the parameter during its wakeup interval.

摘要： Transmit power for an access point is controlled based on information received by the access point. For example, an access point may employ one or more algorithms that use messages received from nearby access terminals to maintain an acceptable tradeoff between providing an adequate coverage area for access point transmissions and mitigating interference that these transmissions cause at nearby access terminals. Here, the access point may employ a network listen-based algorithm upon initialization of the access terminal to provide preliminary transmit power control until sufficient information is collected for another transmit power control algorithm (e.g., an access terminal assisted algorithm). Also, the access terminal may employ an active access terminal protection scheme to mitigate interference the access point may otherwise cause to a nearby access terminal that is in active communication with another access point.

摘要： Transmit power (e.g., maximum transmit power) may be defined based on the maximum received signal strength allowed by a receiver and a total received signal strength from transmitting nodes at the receiver. Transmit power may be defined for an access node (e.g., a femto node) such that a corresponding outage created in a cell (e.g., a macro cell) is limited while still providing an acceptable level of coverage for access terminals associated with the access node. An access node may autonomously adjust its transmit power based on channel measurement and a defined coverage hole to mitigate interference and perform a self-calibration process.

摘要： A carrier for a femtocell is selected from a set of carriers available to femtocells. The femto node determines a preference order for the set and measures received signal strength (RSS) for each carrier. The femto node determines a least interference carrier from the set based on the RSS for each carrier, then defines a selected carrier for the femtocell by comparing the RSS of the least interference carrier to the RSS of other carriers in the set. The selected carrier may have a RSS larger than or equal to the RSS of the least interference carrier offset by a predefined margin. The comparisons may be performed in the preference order. The set available to femto nodes may be a subset of all carriers available to a combination of femtocells and macrocells and one or more of the carriers available to femtocells also may be a carrier available to macrocells.
