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 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 for management of high-speed dedicated physical control channel decoding in soft handover procedures include various methods that include controlling reverse link transmission power. Different algorithms may be used for controlling transmission power, including algorithms summarized as determining path-loss differences, determining a difference between pilot channel power from HSDPA serving and non-serving NodeBs, and adjusting a signal-to-interference target, an attenuation factor, or similar parameters for controlling reverse link power. Another of the management methods includes selecting a HSDPA serving NodeB for a mobile entity jointly based on the downlink and uplink channel quality, loading, and resource availability. The methods, and aspects of the methods, may be embodied in wireless communications apparatus, for example, in a NodeB or mobile entity.

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： Methods and apparatuses are provided for determining whether to handover a device to mitigate uplink interference while achieving acceptable uplink service quality in a wireless network. One or more parameters related to a device can be evaluated to determine whether to handover the device, such as a number of transmission power reports received from the device over a period of time, a frame error rate, setpoint, or power control commands related to the uplink of the device, a received pilot signal strength at the device, an uplink throughput or buffer size at the device, etc., from which transmit power information of the device can be inferred for determining whether the device potentially interferes with access points or devices. Based on the one or more parameters, an access point can determine whether handing over the device may mitigate such uplink interference while ensuring uplink service quality, and accordingly handover the device.

摘要： Methods and apparatuses are provided for determining one or more parameters of an access point that can be set or adjusted to mitigate interference to other access points. A rise-over-thermal (RoT) threshold can be set at an access point based on one or more parameters, such as pathloss measurements, location of the access point, etc., such that interference from devices communicating with the access point can be mitigated. In addition, a noise floor, RoT threshold, etc., can be adjusted based on determining a transmit power difference, out-of-cell interference, and/or similar measurements.
