  • Patent number: 7953104
    Abstract: A technique to allow enhanced stations and legacy stations to work with each other without the inefficiencies of signaling overhead in the prior art is disclosed. An enhanced station transmits an initial, short frame using a modulation compatible with legacy stations. The frame sets the duration for a frame exchange—consisting of a data frame, followed by acknowledgement frame—in which the data frame is transmitted using an enhanced modulation format. The duration specified in the transmitted initial frame covers the time interval of the subsequent frame exchange. All stations, including legacy stations, listen in on the frame exchange and refrain subsequently from transmitting spontaneously for the time interval covered by the duration. Alternatively, the frame exchange can comprise multiple data frames with corresponding acknowledgement frames. The enhanced station can also transmit, during the remaining frame exchange, one or more intermediate frames that indicate duration.

  • Patent number: 7953064
    Abstract: A system is proposed to provide buffer status reporting in a mobile telecommunications environment, particularly applicable to 3GPP networks, which allows the base station to perform Quality of Service aware uplink resource allocation. The system uses two types of buffer status reports—Absolute Buffer Status Reports and Relative Buffer Status Reports. Absolute Buffer Status Reports are sent at application start up or when the buffer level is above or below set threshold values. Otherwise Relative Buffer Status Reports are sent, which encode the present buffer level in terms of the difference from the last transmitted Absolute Buffer Status Report.
