1. Claim1st, a kind of method for transmitting signal, it is characterised in that including:

  • Know in signal radiation pattern, the signal radiation pattern and show that upward signal is launched by multiplex mode;

    According to the signal radiation pattern known, upward signal is launched in upstream band and downstream bands in the way of the multiplexing.2nd, the method for transmission signal according to claim 1, it is characterised in that:

    The upward signal is uplink reference signals;

    AndIt is described that transmitting upward signal includes in upstream band and downstream bands in the way of multiplexing:

    Launch uplink reference signals in upstream band and downstream bands by time-multiplexed mode.3rd, the method for transmission signal according to claim 2, it is characterised in that:

    It is described to launch uplink reference signals in upstream band and downstream bands by time-multiplexed mode and include:

    In units of subframe, in upstream band and downstream bands alternate emission uplink reference signals.4th, the method for the transmission signal according to Claims 2 or 3, it is characterised in that:

    Also include the configuration parameter of uplink reference signals in the signal radiation pattern;

    AndThe signal radiation pattern that the basis is known, transmitting upward signal includes in upstream band and downstream bands in the way of the multiplexing:

    According to the signal radiation pattern known, in upstream band and downstream bands transmitting uplink reference signals in the way of the multiplexing and with reference to the configuration parameter.5th, the method for transmission signal according to claim 4, it is characterised in that:

    The configuration parameter of the uplink reference signals includes the uplink reference signals configuration parameter of upstream band and downstream bands, and the uplink reference signals configuration parameter of the upstream band and downstream bands is identical or different.6th, the method for transmission signal according to claim 5, it is characterised in that:

    Transmit cycle, and/or transmission power, and/or transmitted bandwidth, and/or frequency-hopping mode.7th, a kind of communicator, it is characterised in that including:

    First knows unit, shows that upward signal is launched by multiplex mode for knowing in signal radiation pattern, the signal radiation pattern;

    Transmitter unit, for the signal radiation pattern known according to, upward signal is launched in the way of the multiplexing in upstream band and downstream bands.8th, communicator according to claim 7, it is characterised in that:

    The transmitter unit is specifically for the signal radiation pattern known according to, by time-multiplexed sideFormula launches uplink reference signals in upstream band and downstream bands.9th, communicator according to claim 8, it is characterised in that:

    The transmitter unit further comprises:

    First transmitter unit, in units of subframe, uplink reference signals to be launched by periodicity over-over mode in upstream band and downstream bands;

    And/or,Second transmitter unit, in units of subframe, in upstream band and downstream bands aperiodicity over-over mode transmitting uplink reference signals.10th, communicator according to claim 8 or claim 9, it is characterised in that also include:

    Second knows unit, the configuration parameter for knowing the uplink reference signals that signal radiation pattern further comprises;

    The transmitter unit is specifically in the way of described first knows the multiplexing that unit is known and reference described second knows that the configuration parameter that unit is known launches uplink reference signals in upstream band and downstream bands.11st, a kind of communicator, it is characterised in that including:

    First setting unit, the signal radiation pattern for setting terminal, the signal radiation pattern shows that upward signal is launched by multiplex mode;

    Transmitting element, for sending the signal radiation pattern to terminal, indicates the terminal according to the signal radiation pattern, in upstream band and downstream bands transmitting upward signal in the way of the multiplexing.12nd, communicator according to claim 11, it is characterised in that also include:

    Second setting unit, the configuration parameter for further setting uplink reference signals in signal radiation pattern;
