摘要： A method includes receiving indications of a wake-up interval assigned to a station and a corresponding group to which the station belongs, wherein all stations assigned to the group are assigned the wake-up interval. The method includes waking the station during the wake-up interval and determining, using at least the indication of the group, whether information received by the station during the wake-up interval corresponds to the group. Another method includes assigning stations to one of multiple groups based on wake-up intervals, in which stations assigned to a group all have a same wake-up interval and each group has a different wake-up interval, sending indications of a corresponding wake-up interval and a corresponding group to each of the stations, and during a interval corresponding to the wake-up interval for a selected group, transmitting the indication of the selected group and associated information meant for the group.

摘要： Various example embodiments are disclosed relating to feedback and link adaptation techniques for wireless networks. According to an example embodiment, an apparatus may include a processor or controller. The controller may be configured to determine a channel quality indication (CQI) value for each of a plurality of wireless sub-channels, discard any of the CQI values older than a threshold time, leaving a set of current CQI values, determine a percentile CQI value based on the set of current CQI values, and transmit the percentile CQI value to an infrastructure node. The infrastructure node, may, for example, determine or select one or more data transmission parameters, such as a modulation scheme and/or coding rate, based at least in part on the received percentile CQI value.
