Multi-connection, non-simultaneous frequency diversity in radio communication systems
A radio communication system includes a remote device radio, and a base station radio operable to communicate with the remote device radio at a first channel and at a second channel using non-simultaneous frequency diversity. The base station is operable to communicate with a device other than the remote device at the second channel while the remote device radio and the base station radio are communicating at the first channel. A radio using non-simultaneous frequency diversity includes an antenna, a radio frequency module coupled to the antenna such that the radio frequency module is operable to transmit or receive radio frequency signals at a first channel and signals at a second channel using the antenna, and a baseband module coupled to the radio frequency module. The baseband module operable to transmit or receive signals through the radio frequency module, such that signals transmitted or received by the radio employ non-simultaneous frequency diversity using the first channel and the second channel. Additional devices are operable to use the second channel while the radio is transmitting or receiving radio frequency signals at the first channel.
1 . A radio communication system comprising:
a remote device radio; and
a base station radio operable to communicate with the remote device radio at a first channel and at a second channel using non-simultaneous frequency diversity,
wherein the base station is operable to communicate with a device other than the remote device at the second channel while the remote device radio and the base station radio are communicating at the first channel.
2 . The radio communication system of claim 1 wherein the remote device radio is a subscriber station in a wireless network.
3 . The radio communication system of claim 1 wherein the base station radio is a base station in a wireless network.
4 . The radio communication system of claim 1 further comprising a second remote device radio such that the base station radio is operable to communicate with the remote device radio at the first channel while communicating with the second remote device radio at the second channel.
5 . The radio communication system of claim 1 wherein the remote device radio includes a single transmit/receive path.
6 . The radio communication system of claim 1 wherein the frequency separation between the first channel and the second channel is at least 20 MHz.
7 . The radio communication system of claim 6 wherein the information transmitted on the first channel and the information transmitted on the second transmission channel differ by a complex gain.
8 . The radio communication system of claim 1 wherein the first transmission channel and the second transmission channel are wideband channels.
