Abstract: A communication method and apparatus includes a terminal that receives first control information from a network device. The first control information includes a first field. The first field indicates single-carrier scheduling or the multi-carrier scheduling. When the first field indicates the single-carrier scheduling, the terminal communicates with the network device on one scheduled carrier. Alternatively, when the first field indicates the multi-carrier scheduling, the terminal communicates with the network device on a plurality of scheduled carriers. According to the method and the apparatus in this application, the first field in the first control information may explicitly or implicitly indicate the single-carrier scheduling or the multi-carrier scheduling, and the network device does not need to additionally send a notification message, thereby reducing air interface overheads.

Abstract: A data transmission method includes transmitting, by a first communications apparatus, first data with a second communications apparatus on a first frequency resource. The method also includes sending, by the first communications apparatus, control information to the second communications apparatus. The control information is used to schedule a part or all of the first data transmitted between the first communications apparatus and the second communications apparatus on a second frequency resource. A first transmission mode supported by the first frequency resource is different from a second transmission mode supported by the second frequency resource. Alternatively, the first transmission mode is the same as the second transmission mode, and a first feedback quantity supported by the first frequency resource is different from a second feedback quantity supported by the second frequency resource.

Abstract: Embodiments of the present invention disclose a reference signal transmission method. A transmitting apparatus multiplies M first symbol sequences by M coefficients respectively to obtain M second symbol sequences, where M is a positive integer greater than 1, the symbol sequence includes L symbols, L is a positive integer greater than 1, and the M coefficients each have a magnitude of 1. The transmitting apparatus maps the M second symbol sequences onto a first time-frequency resource to obtain a frequency domain signal. The transmitting apparatus performs an IFFT operation on the frequency domain signal to obtain a time domain signal. And the transmitting apparatus sends the time domain signal.
