摘要： In an adaptive feedback method for a cellular communication system having plural terminals feeding back channel information to an access point, the system selects one of an opportunistic mode and a polling mode as a feedback mode between an access point and the terminals on the basis of system and traffic parameters, sets up the access point and the terminals for the selected feedback mode, and feeds back the channel information from the terminals to the access point in the selected feedback mode. The adaptive feedback method changes the feedback mechanism adaptively to the system and traffic environment, making it possible to increase the system throughput as well as to decrease the MAC overhead regardless of the variation of the number of MSs.

摘要： Methods and apparatus for calibrating an antenna array are provided. A limited number of antenna elements of the array are operated to broadcast a signal. The signal carries information relevant to operation of a communication network, for receipt by other devices. By using one or a limited number of antenna elements, a radiation pattern covering a wide area is achieved. Concurrently, transmission of the broadcast signal is monitored using another one or more antenna elements of the array, operating in a receive mode. The monitored signal is used in an antenna array calibration operation. The procedure is repeated for various different transmitting and receiving antenna elements, resulting in a sequence of broadcasts using different parts of the array. The calibration results can be used to correct for operating errors such as phase shifter errors. The corrected phase shifters can then be used for beamforming during another phase of communication.

摘要： Practical methods and apparatuses are provided for determining network clusters in wireless backhaul networks comprising a plurality of hubs (102) and Remote Backhaul Modules (RBM) (104) based on link quality value (LQV) metrics. From an input LQV table of LQV values for each hub-RBM link (110), the link quality values are first ranked. Clusters are then identified from all the possible links based on the order of the highest link quality value to the lowest link quality value, any constraints on the number of RBMs per cluster, and clustering each RBM only once. Links with strong link quality values are chosen to optimize the LQV metric. LQV based clustering achieves a higher average LQV, e.g., average spectrum efficiency or weighted sum spectrum efficiency, for the entire backhaul network compared to the geographic location based clustering. The method is straightforward to implement and has low computational complexity.

摘要： Methods and apparatus are provided for managing interference in a wireless backhaul network comprising a plurality of hubs, each hub serving a plurality of remote backhaul modules (RBM), using power control with a one-power-zone (OPZ) constraint. Each hub uses a transmit frame structure comprising a plurality of zones, each RBM is scheduled on a different zone, and the same power level is maintained across all zones within a transmit frame. Under the OPZ constraint, and for scheduling policies under which the number of zones assigned to each RBM is fixed, the power and scheduling sub-problems are decoupled. This enables power control independent of scheduling, using methods having lower computational complexity. Methods are disclosed comprising iterative function evaluation or Newton's method approaches based on a weighted sum-rate maximization across the network, which can be implemented in a distributed fashion. Some of the methods can be implemented asynchronously at each hub.

摘要： Methods and devices for dynamic sensitivity control (DSC) in wireless networks are provided by adapting a clear channel assessment threshold (CCAT) on a frame-by-frame basis, based on a destination of a head-of-line (HoL) frame in a medium access control (MAC) layer transmission queue. Two different ways of protecting the communication range among devices in a basic serving set (BSS) are disclosed. In the first way, frames received from a node's BSS are differentiated, at the MAC layer, from frames received from an overlapping BSS (OBSS), and different CCATs are used for frames received from the node's BSS versus frames received from OBSS(s). In the second way, a lower bound on the CCAT value is defined based on the average received signal strength indicator (RSSI) of frames previously received from the node's BSS, and the CCAT is periodically reset to its minimum value.
