Abstract: Adaptive delay management means and method for allocating resources having different Quality of Service (QoS) requirements. A Forward Link (FL) scheduler prepares transmission instances by treating pending data queues according to a priority class, such as Best Effort (BE) and Expedited Forwarding (EF). Data bits from multiple queues are stuffed into a transmission instance. Various metrics are used to generate a set of candidates for transmission and then select and build a next transmission instance from the set of candidates.

Abstract: A method and an apparatus of dynamically setting a rise-over-thermal (ROT) threshold to control user-to-user interferences in a wireless communication system are disclosed. The ROT threshold is set by determining whether an outage of communication has occurred, increasing the ROT threshold by a predetermined increment if the outage has not occurred, and decreasing the ROT threshold by a predetermined decrement if the outage has occurred.

Abstract: Interference that occurs during wireless communication may be managed through the use of fractional reuse and other techniques. In some aspects fractional reuse may relate to HARQ interlaces, portions of a timeslot, frequency spectrum, and spreading codes. Interference may be managed through the use of a transmit power profile and/or an attenuation profile. Interference also may be managed through the use of power management-related techniques.

IPC: H04W52/24

Abstract: Transmit power (e.g., maximum transmit power) may be defined based on the maximum received signal strength allowed by a receiver and a minimum coupling loss from a transmitting node to a 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. Transmit power may be defined based on channel quality. Transmit power may be defined based on a signal-to-noise ratio at an access terminal. The transmit power of neighboring access nodes also may be controlled by inter-access node signaling.

Abstract: A method and apparatus for determining the data rate of a reverse link communication of an access terminal includes receiving a reverse activity bit (RAB) from an access network in the communication system, and passing the RAB to multiple digital filters to produce filtered RABs. The reverse link data rate is determined based on these filtered values of the RABs. From the filtered RAB values a continuous fluid power level is determined for each rate update. The access terminal maps the continuous fluid power level to actual physical transmissions by dithering among discrete power levels allowed by the physical layer.

Abstract: A receiver operates to AGC a multi-carrier signal through a corresponding number of inner loops and an outer loop AGC processes. A first number of bits for representing the multi-carrier signal with a limited amount of interference is determined through a calibration mode process. The first number of bits provides for quantization of the multi-carrier signal at an outer loop AGC to a maximum quantization level. After the received signal power estimate is reached a predetermined "ON" threshold, the outer loop AGC is operated at a second number of bits higher than the first number of bits to allow a quantization of possible interference in accordance with a difference of the first and second number of bits. The outer loop AGC switches back to use the first number of bits when the received signal power estimate falls below a predetermined "OFF" threshold.
