| 20080212612 | Method and system for acknowledgements in wireless communications - A packet communication process for a wireless system that includes a sender and a receiver, is provided. The packet communication process dispenses with the need to send multiple block acknowledgments, one per Traffic Identifier (TID), from the receiver to the sender. This involves aggregating multiple MPDUs having a plurality of different TIDs; for each TID, generating a BAR to request an acknowledgment for one or more MPDUs with that TID from the receiver; transmitting the aggregated MPDUs and the BARs from the sender to the receiver over a wireless channel; receiving the aggregated MPDUs and the BARs at the receiver; in response to the BARs, generating a single block acknowledgement that includes an acknowledgment for each MPDU with a different TID; and transmitting the single block acknowledgement to the sender. | 2008-09-04 |
| 20080212613 | Multilink meshed transport service - One embodiment relates to a method of transporting data packets between a plurality of transport units in a building. Transmit flows are created and associated with source-destination address pairs of new data streams received from outside a network of the transport units. A separate sequence space is provided for each transmit flow. The transmission of the data packets belonging to a same transmit flow is advantageously spread among multiple link-layer links. Other embodiments, aspects and features are also disclosed. | 2008-09-04 |
| 20080212614 | METHOD AND SYSTEM FOR EXTENDING TRANSMISSION DISTANCE OF ADSL SIGNAL - A method for extending transmission distance of an ADSL signal includes: increasing power spectral density (PSD) of an ADSL signal when a parameter of the ADSL signal is equal to or greater than a preset threshold; and sending the ADSL signal with the increased PSD. A system for extending transmission distance of ADSL signal includes a PSD adjustment determining unit, a PSD adjusting unit and a transmitting unit. A method for promoting transmission rate of an ADSL signal is disclosed as well. The solution extends the coverage of the ADSL signal, and when the CO increases the downlink PSD, the CEP need not to be modified, which reduces the cost. | 2008-09-04 |
