Abstract: Methods and apparatus for synchronizing a global time reference for access points over the air are provided. In one aspect, a method for synchronizing a global time of an access point comprises receiving a message comprising a global time indication from a second access point. The method further includes updating the global time of the access point to the global time indication from the second access point by updating a timer of the access point by an increment not to exceed a predetermined value selected small enough to ensure a maintenance of synchronization between the access point and at least one associated wireless station. The global time of the access point is updated to the global time indication from the second access point when the global time indication from the second access point indicated a later global time than the global time of the access point.

Abstract: Systems and methods for multi-hop service discovery within a mobile device cluster are disclosed. A seeker station may be seeking or may have found a desired service available from a provider station. The seeker station may receive the service announcement from the provider station, and become a proxy station, expanding the service area of the provider station. The proxy station may selectively transmit services and advertisements for services on behalf of the provider station based on restrictions placed on selection as a proxy station. Restrictions or conditions may be placed on the proxy station limiting the number of stations that may become proxy stations, limiting traffic within the cluster. Some restrictions may require a proxy station to be a member of the cluster or a member of a group within the cluster. Selection as a proxy station and frequency of transmission of service announcements by proxy stations may also be conditioned on various specific parameters or combinations of parameters as specified by the provider station.

Abstract: A method includes receiving a data fragment of a block of data fragments of a single data unit from a wireless device at a receiver. The method includes, in response to determining that the data fragment is a last data fragment of the block of data fragments, transmitting an acknowledgement to the wireless device. The acknowledgement indicates whether each data fragment of the block of data fragments was received from the wireless device. The method includes, in response to determining that the data fragment is a last data fragment of the single data unit, transmitting the acknowledgment to the wireless device. The method further includes, in response to determining that the data fragment is not the last data fragment of the block of data fragments or the last data fragment of the single data unit, refraining from transmitting the acknowledgement to the wireless device.
