20110085502 | BLIND DECODING OF UPLINK CONTROL CHANNELS - In 3GPP LTE, the uplink ACK and CQI bits are jointly coded prior to transmission to maintain a low peak to average ratio (PAR) waveform. Further, when data needs to be transmitted, the uplink control channels are multiplexed with data prior to transmission. However, due to errors on downlink (DL) and uplink (UL) assignments, an evolved Base Node (eNB) receiver needs to employ a set of rules to decode the control channels, to minimize the number of blind decoding hypotheses.

20110085595 | SIGNAL COMPRESSING SYSTEM - A multi-scanner scans a signal according to several different patterns. A scanning pattern selector determines which scanning pattern produced the most efficient coding result, for example, for runlength coding, and outputs a coded signal, coded most efficiently, and a selection signal which identifies the scanning pattern found to be most efficient. | 2011-04-14 |
