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 multi-link access point (AP) device is configured for multi-link operation to communicate with a plurality of non-AP stations (STAs) over a plurality of corresponding links. A multi-link policy element is encoded for transmission to the non-AP STAs to signal a multi-link policy. The multi-link policy element comprises a common policy sub-element and a plurality of link-specific policy sub-elements. The common policy sub-element is applicable to all links. Each of the link-specific policy sub-elements is applicable to a single link. The link-specific policy sub-elements comprise at least a first link-specific policy sub-element applicable to a first link and a second link-specific policy sub-element applicable to a second link. The common policy sub-element defines a link policy for all links that have been set up between the multi-link AP device and the non-AP STAs. Each link-specific policy element defines a link policy specific to an associated link.

摘要： Computing readable media, apparatuses, and methods for random access with carrier sensing are disclosed. An apparatus is disclosed including processing circuitry configured to: decode a trigger frame, the trigger frame to indicate resource units (RUs) for random access and to indicate if a carrier sense (CS) is to be performed. The processing circuitry may be further configured to: decrement a value of an orthogonal frequency division multiple-access (OFDMA) backoff (OBO) field based on a number of the RUs indicated for random access. The processing circuitry may be further configured to: when the value of the OBO field reaches a predetermined value, randomly select one of the RUs indicated for random access, and if the CS is to be performed, determine a virtual CS based on one or more network allocation vectors (NAVs) and perform a physical CS on the selected RU, and if the virtual CS and the physical CS both indicate that the selected RU is idle, configure the wireless device to transmit a physical (PHY) layer convergence procedure (PLCP) protocol data units (PPDU) on the selected RU in accordance with OFDMA.
