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： A first access node of a first network utilizes code sequences, assigned to different user devices, to distinguish at least acknowledgements received in parallel or sequentially from those user devices. The first access node determines from received signaling that a root sequence of the code sequences is in use by a second access node of a second network, then changes that root sequence of the code sequences assigned to the different user devices. In certain examples the access nodes are WLAN access points APs and the acknowledgements are received in response to a group probe/poll. In various embodiments the first AP monitors its neighbors' group probes/polls to learn the root sequences/basic service sets in use in those neighbor networks, or the AP's own stations monitor and send the information in neighbor reports. This latter option can be initiated by the stations themselves, or by the AP.
