Abstract: A method and apparatus may be used for assigning groups of stations in wireless communications to one or more groups. Groups may be assigned by an access point (AP) based on information received from a station (STA). Group information may be signaled to each station and a group identifier may be indicated in a frame. The group information may be applied to a performance enhancement, for example power savings for the station, wherein the station enters a power saving mode on a condition that the station determines that it is not a member of the group.

Abstract: The application relates to various aspects for modeling software, preferably for use in wireless communication devices. One aspect relates to targeting a software model to a plurality of different operating systems/operating system combinations. Another aspect relates to abstracting the operating environment to an operating system/operating system combination. Another aspect relates to handling inter-processor communication. Another aspect relates to a common time manager.
