orthogonal frequency division multiplexing symbols used by the base station for transmitting the evolved control signaling on the M subframes are different from orthogonal frequency division multiplexing symbols used by the base station for transmitting basic control signaling.

2. The method according to claim 1 , wherein,
N is divisible by M;
or the M downlink subframes are first M downlink subframes in the radio frame;
or when N is divisible by M and M is greater than 1, two adjacent downlink subframes in the M downlink subframes for transmitting the evolved control signaling are spaced by ((N/M)−1) subframes;
or when N is not divisible by M and M is greater than 1, two adjacent downlink subframes in the M downlink subframes for transmitting the evolved control signaling are spaced by floor((N/M)−1) subframes, wherein, floor is a round down function;
or when N is not divisible by M and M is greater than 1, two adjacent downlink subframes in the M downlink subframes for transmitting the evolved control signaling are spaced by floor(N/M) subframes, wherein, floor is a round down function.

3. The method according to claim 1 , wherein,
positions of the M downlink subframes for transmitting the evolved control signaling in the radio frame are configured by default; or the base station notifies the evolved terminal of the positions of the M downlink sufbrames for transmitting the evolved control signaling in the radio frame through signaling.

4. The method according to claim 1 , further comprising:
the base station transmitting basic control signaling only on other downlink subframes except the M downlink subframes in the radio frame; or the base station transmitting the basic control signaling only on the M downlink subframes.

8. The method according to claim 1 , wherein,
the base station only transmits the evolved control signaling in the radio frame.

9. The method according to claim 1 , wherein,
time-frequency resources used by the base station for transmitting the evolved control signaling are configured by default, or are notified by the base station to the evolved terminal through signaling.

10. The method according to claim 1 , wherein,
downlink time-frequency resources allocated to the evolved terminal in the evolved control signaling are located on multicast broadcast single frequency network subframes of the radio frame; or the downlink time-frequency resources allocated to the evolved terminal in the evolved control signaling are inter-subframe resources or inter-frame resources.

11. The method according to claim 1 , wherein,
the basic control signaling is basic control signaling related to the evolved terminal.
