摘要： A method for providing visible notification by a device in a visible-light-communication system based on Institute of Electrical and Electronic Engineers (IEEE) standard 802.15.7, wherein higher levels are allowed to invoke through one standardized interface a medium-access-control sub-layer to provide color-function support and enables invocation of a transmission of color, visibility, and dimming frames by a higher layer, which creates a unified interface between the MAC sub-layer and the higher layers, while providing a primitive for requesting, by the at least one upper layer to the at least one interface of the medium-access-control entity layer, a transmission of at least one visibility frame.

摘要： A congestion notification element for indicating a congestion status of a mesh node may include at least one field specifying a mesh destination for which an intra-mesh congestion control is to be applied. This may allow for forwarding data frames on paths that share some links but not the bottleneck link with a path that is congestion controlled, which has not been possible with currently specified congestion notification techniques.

摘要： A method is provided for configuring temporal parameters of an access scheme synchronized with other access schemes in a wireless mesh network based IEEE 802.11s specifications. In conventional access schemes an unsuitable choice of parameters at different neighboring mesh stations, especially an unsuitable choice of different DTIM intervals at the different neighboring mesh stations, will lead to overlapping reservations in some intervals. Thus, a method for setting a DTIM interval of a mesh station is provided, whereby a joining mesh station determines a DTIM interval of at least one mesh station of the wireless mesh network, and whereby the joining mesh station sets its own DTIM interval to the same DTIM interval, to a multiple of the DTIM interval, or to a fraction of the DTIM interval of at least one mesh station of the wireless mesh network, wherein the factor and the divisor are positive integers.
