ENABLING FULL-DUPLEX COMMUNICATION IN LEGACY LTE SYSTEMS
First Claim
1. A method for converting from half-duplex communication to full-duplex communication in a legacy wireless cellular system having a base station, the method comprising:
- providing in the base station separate transmit and receive paths for transmit signals and receive signals, respectively;
converting an uplink frequency band and a downlink frequency band for the base station to a same frequency band; and
applying analog signal cancellation techniques at the base station to isolate a full-duplex wireless reception signal from a full-duplex wireless transmission signal.

Abstract
Methods are provided for converting from half-duplex communication to full-duplex communication in a legacy wireless cellular system having a base station. A method includes providing in the base station separate transmit and receive paths for transmit signals and receive signals, respectively. The method further includes converting an uplink frequency band and a downlink frequency band for the base station to a same frequency band. The method also includes applying analog signal cancellation techniques at the base station to isolate a full-duplex wireless reception signal from a full-duplex wireless transmission signal.

19. A method for converting half-duplex communications to full-duplex communications, comprising:
-
providing a first legacy base station and a second legacy base station, each configured to use a same uplink frequency band and a same downlink frequency band for the half-duplex communications; and switching the uplink frequency band with the downlink frequency band for only one of the base stations to provide the full-duplex communications for client devices interconnected through the base stations. - View Dependent Claims (20)
