Abstract: Methods and apparatuses are provided for causing active hand-in of a device from a macrocell base station to a femto node, which can be an inter-frequency hand-in. The femto node can broadcast a beacon, which can be received and reported by a device to a source base station along with one or more parameters. The source base station can communicate a handover message to the femto node or a related femto gateway along with the one or more parameters. The femto node or femto gateway can disambiguate the intended target femto node based in part on the one or more parameters, which can include applying one or more filters. Applying the one or more filters may include applying an UL RSSI filter to the one or more femto nodes to determine whether presence of the device causes a rise in UL RSSI measured at the one or more femto nodes.

Abstract: Techniques are provided for utilizing selected inter-frame spacing, such as reduced inter-frame spacing (RIFS) or short inter-frame spacing (SIFS) to avoid failed data transmissions in a Wi-Fi network or the like. For example, there is provided a method, operable by a transmitter node or entity, such as, for example, an access point (AP), that may involve sending a data transmission in a data aggregation mode, the data transmission comprising aggregated MAC protocol data units (A-MPDUs). The method may involve monitoring for and detecting potential short interference bursts in the network. The method may involve re-sending the data transmission in a data bursting mode, the data transmission comprising back-to-back data packet bursts separated by a selected inter-frame spacing.
