Abstract: System and method embodiments are provided for provisioning a quality of cellular user experience (QoE) or quality of service (QoS) specified device in a wireless local area network (LAN). The embodiments enable a QoE or QoS specified by a service agreement for a device to be maintained during periods when the device is transmitting data to and receiving data from the wireless LAN (e.g., a WiFi hotspot). In an embodiment, a method includes determining that at least one QoS-sensitive device is communicating with a wireless LAN access point (AP), reserving a contention free period (CFP) in a superframe for the at least one QoS-sensitive device to communicate with the AP, and allocating a contention period (CP) in the superframe for non-QoS-sensitive devices to communicate with the AP, wherein the non-QoS-sensitive devices are prohibited from transmitting during the CFP.

Abstract: Various devices and methods are provided that use signaling to support advanced wireless receivers. For example, a method includes receiving an input signal at a user equipment. The input signal includes a desired signal and an interfering signal, where the desired signal defines symbols using constellations. The method also includes obtaining information identifying a wireless channel used by the interfering signal and a modulation type used to modulate data in the interfering signal. The method further includes recovering the symbols from the desired signal using the information.

Abstract: A method for configuring a first base station within a cluster in a communications system having a plurality of cluster includes optimizing an operating parameter of the first base station in accordance with first utility function results from a first utility function associated with the first base station and second utility function results from a second utility function associated with a second base station within the cluster, the first utility function results and the second utility function results according to multiple settings for the operating parameter of the first base station, a first initialized setting of the operating parameter for the second base station, and a second initialized setting of the operating parameter for an external base station outside the cluster. The method also includes sharing the optimized operating parameter with the external base station.

Abstract: The present disclosure concerns the harnessing of the effect of a relay to enhance the ability to avoid the effect of interference at mobile stations. This is achieved either by overlaying beamforming for an indirectly reached mobile station so that a relay passes on this beamforming to the mobile station concerned, and retaining orthogonality therewith, or by harnessing a base station and a relay station together so that their combined effect is to provide spatial multiplexing to two or more mobile stations.

Abstract: According to one embodiment there is provided a method performed in a transmitter side of a multiuser minimum square error linear precoding MIMO system that comprises a transmitter with a plurality of transmit antennae and a plurality of receivers. Each receiver of the plurality of receivers comprises a plurality of receive antennae. The method is a method of scheduling receivers from among the plurality of receivers and comprises obtaining, for some or all of the receivers, receiver channel information that quantifies the properties of transmit channels between receiver antennae of the receiver and transmit antennae of the transmitter and establishing an order for determining the receiver combining vectors of the some or all of the receivers. The order is established by selecting as a next receiver in the order a so far unselected receiver from the some or all of the receivers that minimally increases the mean square data transmission error.

Abstract: In a wireless communications system, a method of processing data prior to transmission thereof to a plurality of stations. The method includes determining a channel matrix using a plurality of weighted channel responses, each of which is associated with one of the plurality of stations and weighted by a gain factor corresponding to the station, wherein the gain factor is inversely proportional to a noise power of the station. The data is then processed in accordance with a precoding scheme using the determined channel matrix.
