Abstract
A conventional UE in a radio system based on LTE may be boosted for use in an extended geographical cell provided by an eNodeB. The booster may be connected to the UE in various ways which minimise the changes required to an otherwise standard UE device. The booster is activated by control signals from the UE, or by an internal switch, or by a power detector for example. Power headroom reports by the UE to the eNodeB are correct within the larger cell.
Claims21
A radio for use in a mobile radio network, including:
- a user terminal having a transceiver, a power controller and an antenna;
- and
- a power booster having an amplifier and an amplifier bypass, under control of the user terminal;
- wherein the booster is coupled between the transceiver and the antenna to form a signal path for transmission of radio signals by the terminal, and
- the power controller switches the signal path between the amplifier and the amplifier bypass according to transmitter power required from the user terminal.
A radio for use in a mobile radio network, including:
- a user terminal having a transceiver, a power controller and an antenna;
- and
- a power booster having an amplifier which is coupled between the transceiver and the antenna to form a signal path for transmission of radio signals by the terminal to the network,
- wherein the power controller generates a power headroom report for the network including the power available from the booster, and
- the power controller correspondingly calculates power output from the user terminal including a decrease by the power available from the booster.
A radio for use in a mobile radio network, including:
- a user terminal having a transceiver, a power controller and an antenna;
- and
- a power booster having an amplifier which is coupled between the transceiver and the antenna to form a signal path for transmission of radio signals by the terminal to the network,
- wherein the power controller generates a power headroom report for the network not including the power available from the booster, and
- the power controller correspondingly receives control signals from the network which decrease the power output from the user terminal by the power available from the booster.
A radio for use in a mobile radio network, including:
- a user terminal having a transceiver and an antenna;
- and
- a power booster having an amplifier, an amplifier bypass, and a power controller;
- wherein the booster is coupled between the transceiver and the antenna to form a signal path for transmission of radio signals by the terminal, and
- the power controller switches the signal path between the amplifier and the amplifier bypass according to transmitter power received from the transceiver.
A booster for use with a UE terminal, including:
- a pair of switches,
- an RF power input for connection to an output of the UE,
- an RF power output for connection to an antenna,
- an amplifier and an amplifier bypass connected in parallel between the switches, and
- a controller which operates the switches to connect either the amplifier or the bypass between the power input and the power output, according to power requirements of the UE.
