1. A wireless communications method in an M2M (machine-to-machine) system, the method comprising:
acquiring a frequency domain spreading factor, a symbol-level spreading factor, and a transmission time interval-level spreading factor; and wherein the method further comprises:
performing frequency domain spreading, symbol-level spreading, and transmission time interval-level spreading on first to-be-sent information according to the acquired frequency domain spreading factor, symbol-level spreading factor, and transmission time interval-level spreading factor, respectively, to obtain first spread information, and sending the first spread information to a base station;or,receiving second spread information sent by a base station, and performing frequency domain despreading, symbol-level dispreading, and transmission time interval-level despreading on the received second spread information according to the acquired frequency domain spreading factor, symbol-level spreading factor, and transmission time interval-level spreading factor, respectively, wherein the second spread information is information obtained after the base station performs frequency domain spreading, symbol-level spreading, and transmission time interval-level spreading on second to-be-sent information according to the frequency domain spreading factor, the symbol-level spreading factor, and the transmission time interval-level spreading factor, respectively.
