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： Methods and apparatuses are provided for adjusting a scheduled load for one or more user equipment (UE) in a wireless network. A comparison of each of one or more control parameters related to signals received from one or more UEs to a corresponding threshold can be determined. The control parameters can correspond to an in-cell load, rise-over-thermal, etc. The scheduled load of a base station can be adjusted based in part on the comparison. This adjustment can include adjusting the scheduled load by a step-size increase value or step-size decrease value, which can be computed based in part on a target tail probability for the one or more control parameters.

摘要： Grant channel resources are allocated based on the number of access terminals that use different types of transmission time intervals (TTIs) for data transmissions. For example, if the number of access terminals using a first type of TTI exceeds the number of access terminals using a second type of TTI, more grant channel resources are allocated to the access terminals that use the first type of TTI.

摘要： Methods and apparatuses are provided that include adjusting rise-over-thermal (RoT) or noise rise (NR) threshold based on detecting interference from one or more devices. A device can communicate within close proximity of a femto node such that the device does not respond to power down commands from the femto node due to operating at a minimum transmit power. The device can cause the RoT or NR at the femto node to potentially rise over a threshold, however. Thus, the femto node can increase the RoT or NR threshold to allow the device to communicate with the femto node without impacting other devices communicating with the femto node. Out-of-cell interference from devices communicating with other base stations can be detected as well, and the RoT or NR threshold can be adjusted based thereon.

摘要： A small base node such as a Home Base Node (HNB), or femto cell, may reduce its transmit power in order to prevent co-channel or adjacent channel interference, or to limit its coverage area. Once the power is set, the HNB signal to a served Home User Equipment (HUE) its transmit Common Pilot Channel (CPICH) transmit power for accurate path loss estimation. When this power is outside of the permissible range, the HNB adjusts other parameters (such as Random Access Channel (RACH) constant value) to compensate for the error in signaled CPICH power, and thus compensate in that process the error in determining path loss. Similarly, if the uplink sensitivity is adjusted, to prevent interference, parameters would also be adjusted and signaled to the HUE to reflect the link imbalance.

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.
