    摘要： For allowing a high level of performance quality within a network while reducing computational method complexity a method for operating a wireless network is claimed, wherein at least one MIMO (Multiple Input Multiple Output) group of different stations will be constructed by means of a grouping algorithm based on a grouping metric for providing a MIMO group of different stations which can be addressed simultaneously in space by a base station using MIMO techniques and meeting a definable level of performance quality and wherein the grouping metric is based on an SINR (Signal-to-lnterference and Noise Ratio) experienced by each station within the MIMO group. The method is characterized by the following steps: computing an SNR (Signal-to-Noise Ratio) that a new station would experience without any interference when added to an already existing MIMO group; computing an SINR estimate by correcting the SNR with the sum of the spatial correlations between the new station and each of the stations already present in the existing MIMO group; and using the SINR estimate for deciding whether the new station can be added to the existing MIMO group meeting the level of performance quality. Further an according network and device is claimed, preferably for carrying out the above mentioned method.

    摘要： A method of scheduling periodic processes for execution in an electronic system, in particular in a network, in a data processor or in a communication device, wherein the electronic system includes a controller for performing the scheduling, wherein a number of N processes Pi are already scheduled with each process Pi having an individual service interval Sli, and wherein an additional process PN+1 is to be scheduled with a service interval SIN+1, is characterized in that the additional process PN+1 is scheduled in such a way that the minimum time lag between the execution times of the additional process PN+1 and the execution times of the number of N already scheduled processes Pi is maximized. Furthermore, a corresponding device for scheduling periodic processes for execution in an electronic system is disclosed.

    摘要： A method for operating a mobile terminal as access point, wherein the access point composes a network together with one or more associated client stations, wherein the access point has an operational mode of alternating awake and sleep periods, and wherein the access point broadcasts beacon frames at regular intervals for signaling communication parameters to the associated client stations, is characterized in that the access point, based on the level of activity in the network, adjusts the communication parameters by slowing down or accelerating the access of the associated client stations to the network. Furthermore, a corresponding mobile terminal is disclosed.

    摘要： For allowing an accurate and reliable estimation of maximum capacity required within a link of a network or within a network at low computational cost a method for controlling the admission of a flow to a network, particularly a WiMAX (Worldwide Interoperability for Microwave Access) network, is claimed, wherein an estimation of maximum capacity required within a link of the network and/or within the network will be performed for examining, whether the flow requesting to enter the network with at least one QoS (Quality of Service) reservation of resources can be admitted, by finding first sets of intersections between all pairs of QoS reservations, i.e. the QoS reservations already accepted within the link and/or within the network and the at least one QoS reservation requested by the flow. The method is characterized by structuring the found sets of intersections by building a matrix of intersections of QoS reservations and - based on said matrix - deriving the rest of the sets of intersections between the intersections found, based on information obtained regarding the QoS reservations involved in each intersection. Further, an according network is claimed, preferably for carrying out the above mentioned method.

    摘要： A method for operating a wireless terminal as an access point - access point terminal (2) - that connects a set of one or more client terminals (4) to an external network, wherein a schedule of absence periods is established during which said connected client terminals (4) are not allowed to transmit data to said access point terminal (2), wherein the absence periods together with corresponding presence periods are scheduled at regular intervals and have certain durations, is characterized in that an adaptation of the absence/presence periods' duration and/or interval parameters is executed on the basis of the bandwidth available in said external network and the amount of traffic transmitted between said access point terminal (2) and said connected client terminals (4). Furthermore, a corresponding wireless terminal is disclosed.
