摘要： In a wireless communication system in which a user using a mobile equipment requests a serving cell handoff from a source cell to a target cell, the mobile equipment monitors authorization for the handoff from the target cell. At the same time, the mobile equipment can decode data from either the source cell or the target cell. Upon receipt of authorization for the handoff, the mobile equipment sends confirmation of the handoff to the target cell.

摘要： Techniques for supporting data transmission on multiple carriers in a wireless communication system are described. A user equipment (UE) may determine available transmit power for data transmission on multiple carriers. The UE may distribute the available transmit power to multiple carriers (e.g., using uniform power distribution, greedy filling, water filling, etc.) to obtain allocated transmit power for data for each carrier. The UE may send at least one resource request with information indicative of the allocated transmit power for each of the multiple carriers to a Node B. The UE may receive at least one resource grant with information indicative of granted transmit power for each of at least one carrier, which may be all or a subset of the multiple carriers. The UE may send data on the at least one carrier and may limit its transmit power for each carrier to the granted transmit power for that carrier.

摘要： Systems and methodologies are described that facilitate dynamic load balancing in a communications network. In particular, one or more mobile devices can send random access preambles on an uplink frequency paired to a downlink frequency employed to connect the one or more mobile devices to a base station. The base station can determine if an uplink frequency load imbalance exists based upon the random access preambles. The base station can transmit an indicator on an acquisition indicator channel to at least one mobile device wherein the indicator includes a command to transition to a new uplink frequency. The mobile device can switch uplink frequencies in response to the command.

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： 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.
