| 20080205328 | Method of scaling soft symbols of an uplink enhanced dedicated transport channel (E-DCH) and method for enabling use of a log-map turbo decoding algorithm for processing the E-DCH - A method of scaling soft symbols of an uplink E-DCH is provided, where the E-DCH is received from a user in a network for processing in a base station receiver in the network employing a log-MAP turbo decoding algorithm to process the E-DCH. The E-DCH includes an E-DPDCH from which the soft symbols are generated at the base station receiver, and an E-DPCCH used to transmit control information associated with the E-DPDCH, which along with configuration information from a radio network controller (RNC) of the network enables the base station receiver to determine a reference amplitude ratio linked to the actual power offset of the E-DPDCH from the legacy DPCCH. In the method, a reference E-DPDCH to DPCCH amplitude ratio is multiplied by a value greater than 1 to output a scaling factor, and the soft symbols are scaled by the scaling factor for processing by the log-MAP turbo decoding algorithm in the base station receiver. | 08-28-2008 |
| 20080205329 | Method of scaling soft symbols of an uplink enhanced dedicated transport channel (E-DCH) and method for enabling use of a log-map turbo decoding algorithm for processing the E-DCH - A method of scaling soft symbols of an uplink E-DCH is provided, where the E-DCH is received from a user in a network for processing in a base station receiver in the network employing a log-MAP turbo decoding algorithm to process the E-DCH. The E-DCH includes an E-DPDCH from which the soft symbols are generated at the base station receiver, and an E-DPCCH used to transmit control information associated with the E-DPDCH, which along with configuration information from a radio network controller (RNC) of the network enables the base station receiver to determine a reference amplitude ratio linked to the actual power offset of the E-DPDCH from the legacy DPCCH. In the method, an estimated E-DPDCH to DPCCH amplitude ratio that represents a scaling factor for the soft symbols is determined, and the soft symbols are scaled by the scaling factor to enable the soft symbols to be processed by the log-MAP turbo decoding algorithm in the base station receiver. | 08-28-2008 |
| 20080268918 | Methods and apparatuses for power reduction in transceivers - In a method for power reduction at a receiver, a first radio frame is processed to recover transmitted data based on transport format information. The transport format information is determined based on a combination of transport format information associated with a plurality of received radio frames rather than a single frame. In another method for power reduction at a receiver, whether transport format information associated with a first radio frame is different from transport format information associated with a second radio frame is determined. The transport channel data is then processed based on the determination. The first radio frame is received prior to the second radio frame, and the transport format information indicates a transport format for transport channel data received in the first and second radio frames. | 10-30-2008 |
| 20090034483 | Methods for detecting acknowledgement channels using probabilities - A first transceiver determines whether a second transceiver has properly decoded at least one of a received data packet and control information associated with the corresponding data packet based on an estimated probability. The estimated probability is indicative of whether the second transceiver has properly decoded at least one of the data packet and associated control information. | 02-05-2009 |
