摘要： Techniques for controlling data transmission are described. In an aspect, a user equipment (UE) determines whether to send a packet based on available transmit power. The UE determines a first packet size based on the available transmit power and sends a packet of the first packet size if it is equal to or larger than a minimum packet size. The UE sends a packet of a second packet size (e.g., the minimum packet size) if the first packet size is smaller than the minimum packet size and if at least one condition is met, e.g., the available transmit power is greater than a power threshold and the delay of a packet to send is larger than a delay threshold. In another aspect, the UE operates in a discontinuous transmission (DTX) mode and cancels the DTX mode if the delay of a packet to send exceeds a threshold.

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 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： 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： Methods and apparatuses are provided for determining a transmission power cap for one or more devices based at least in part on pathloss measurements to one or more access points received from the one or more devices. A common transmission power cap can also be computed for assigning to devices communicating with an access point, and the transmission power cap for a given device can be adjusted when the transmission power is at or a threshold level from the common power cap to conserve signaling in the wireless network. Adjustment of the transmission power cap can additionally or alternatively be based on a received power at an access point related to signals from the device, an interference report from one or more access points, and/or the like.

摘要： In a multi-level power transmission scheme, an access point transmits at one power level, while repeatedly transmitting at a burst power level for short periods of time. For example, a femto cell may transmit a beacon with periodic high power bursts of short duration, while the femto cell transmit power also undergoes high power bursts aligned with the beacon bursts. In a network listen-based power control scheme, an access point listens for one or more parameters sent over-the-air by the network and then defines transmit power based on the received parameter(s). In some aspects, beacon transmit power may be set based on a defined outage radius parameter and the total received signal power on a channel. In some aspects, access point transmit power may be set based on a defined coverage parameter and the received energy associated with signals from access points of a certain type.
