摘要： Systems and methodologies are described that provide techniques for generating and utilizing reverse link feedback for interference management in a wireless communication system. Channel quality and/or interference data can be obtained by a terminal from a serving sector and one or more neighboring sectors, from which an interference-based headroom value can be computed that contains interference caused by the terminal to an allowable range. The interference-based headroom value can then be provided with power amplifier (PA) headroom feedback to the serving sector. Based on the provided feedback from the terminal, the serving sector can assign resources for use by the terminal in communication with the serving sector. Further, the serving sector may choose to honor or disregard a received interference-based power value based on quality of service and/or other system parameters.

摘要： System(s) and method(s) that facilitate assignment mismatch recovery are provided. A projected level of resources required to satisfy one or more communication constraints (e.g., inter-cell and intra-cell interference) is generated. The projected resources are contrasted with scheduled resources and a determination is made as to whether a mismatch between assigned and projected resources exists. A mismatch is recovered through an adaptive response that feeds back magnitudes for the communication resources which are compatible with the communication constraints.

摘要： Systems and methods of scheduling sub-carriers in an OFDMA system in which a scheduler takes into account channel conditions experienced by the communication devices to optimize channel conditions. The scheduler can partition a set of sub-carriers spanning an operating bandwidth into a plurality of segments. The segments can include a plurality of global segments that each includes a distinct non-contiguous subset of the sub-carriers spanning substantially the entire operating bandwidth. One or more of the global segments can be further partitioned into a plurality of local segments that each has a bandwidth that is less than a channel coherence bandwidth. The scheduler determines channel characteristics experienced by each communication device via reporting or channel estimation, and allocates one or more segments to communication links for each device according to the channel characteristics.

摘要： Apparatuses and methodologies are described that increase system capacity in a multi-access wireless communication system. Spatial dimensions may be utilized to distinguish between multiple signals utilizing the same channel and thereby increase system capacity. Signals may be separated by applying beamforming weights based upon the spatial signature of the user device-base station pair. Grouping spatially orthogonal or disparate user devices on the same channel facilitates separation of signals and maximization of user device throughput performance. User devices may be reassigned to groups periodically or based upon changes in the spatial relationships between the user devices and the base station.

摘要： Techniques for controlling transmit power and the amount of overlapping in a quasi-orthogonal system are described. A base station for a sector receives transmissions from terminals in that sector and neighbor sectors and determines performance metrics (e.g., overall throughput) and/or QoS metrics (e.g., minimum data rate) for the terminals in the sector. The base station updates an overlapping factor based on the performance metrics and updates a QoS power control parameter based on the QoS metrics. The overlapping factor indicates the average number of overlapping transmissions sent simultaneously on each time-frequency block usable for data transmission. The QoS power control parameter ensures that the terminals in the sector can achieve minimum QoS requirements. A power control mechanism with multiple loops is used to adjust the transmit power of each terminal. The overlapping factor and QoS power control parameter are updated by two of the loops.
