| 20130010718 | OVERLAY OF BEARERS IN A RADIO COMMUNICATION SYSTEM - A radio system having multiple bearers overlays a relatively narrowband bearer such as P25 on a relatively wideband bearer such as LTE, for transmission of both uplink and downlink signals. The wideband bearer uses a spectrum of subcarriers which form a set of radio frequency blocks. One or more blocks or other related parts of the spectrum may be allocated to the narrowband bearer. In some cases the narrowband bearer may push through the wideband allocation using a relatively high power to dominate signals transmitted by the wideband bearer. Voice calls such as emergency calls using the narrowband bearer may be prioritised. | 01-10-2013 |
| 20130010622 | MULTIPLE BEARER RADIO SYSTEMS - Multiple bearers such as LTE and P25 in a radio system are used to provide diversity and therefore more reliable signal transmissions. The bearers are ranked according to one or more quality characteristics and uplink or downlink messages are transmitted using the best available path at that time. Emergency messages are transmitted simultaneously on all available bearers. | 01-10-2013 |
| 20120282866 | RADIO TRANSCEIVER ARCHITECTURE - A radio transceiver architecture having transmitter and receiver paths. The receiver path has a frequency down conversion stage which creates an incoming IF signal from an incoming RF signal. The transmitter path has a frequency up conversion stage which creates an outgoing RF signal from an outgoing IF signal and a feedback IF signal. The feedback IF signal is created from the outgoing RF signal by the frequency conversion stage in the receiver path. | 11-08-2012 |
