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： Methods and apparatuses are provided that include adaptively configuring a rise-over-thermal (RoT) threshold at a base station to improve communications with one or more devices while mitigating interference to one or more other base stations. A potential device pathloss to the macrocell can be computed based on a measured pathloss thereto applied with a coverage area of the low power base station to emulate a worst-case device, one or more received measurement reports, and/or the like. The RoT threshold can be computed based at least in part on the pathloss and/or a maximum interference level at the macrocell. In addition, the RoT threshold can be adapted based on a reverse link attenuation level.

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.

摘要翻译： 提供了包括基于检测来自一个或多个设备的干扰来调整上升热（RoT）或噪声上升（NR）阈值的方法和装置。 设备可以在毫微微节点的非常接近的范围内通信，使得设备由于以最小的发射功率运行而不响应来自毫微微节点的掉电命令。 然而，该设备可能导致毫微微节点处的RoT或NR潜在地超过阈值。 因此，毫微微节点可以增加RoT或NR阈值，以允许设备与毫微微节点通信，而不影响与毫微微节点通信的其他设备。 也可以检测来自与其他基站通信的设备的小区外干扰，并且可以基于此来调整RoT或NR阈值。

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： A parameter for transmission by an access point is determined in a manner that facilitates access terminal mobility. For example, a cell reselection parameter and/or a handover parameter may be determined based on the quality of a signal from one access point (e.g., a macro cell) at another access point (e.g., a femto cell). In addition, a cell reselection parameter and/or a handover parameter may be determined based on the proximity of one access point (e.g., a femto cell) to another access point (e.g., a macro cell). Through the use of these techniques, a parameter may be determined in a manner that mitigates access terminal ping-ponging between access points and that mitigates outages that may otherwise occur as a result of an access terminal remaining on an access point too long.

摘要： An access point (e.g., a femto cell) that is connected in an active call with an access terminal may cooperate with that access terminal or another access terminal to derive timing information from one or more neighboring access points (e.g., macro access points). In addition, an access point may cooperate with an idle access terminal to derive timing information from one or more neighboring access points. For example, an access terminal may determine the difference between pilot transmission timing or frame transmission timing of a femto cell and a macro cell, and report this timing difference to the femto cell. Based on this timing difference, the femto cell may adjust the timing and/or frequency of its transmissions so that these transmissions are synchronized in time and/or frequency as per network operation requirements.

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.
