Abstract

Example methods and apparatus for sending a signal are described. One method includes determining a to-be-sent first signal by a first terminal and determining a first time-frequency resource. Some or all of the first time-frequency resource are second time-frequency resources, and the second time-frequency resource is a time-frequency resource used to send a second signal. The first signal is sent by the first terminal by using the first time-frequency resource, where the first time-frequency resource includes an idle time-frequency resource that is not occupied by the second signal. The first time-frequency resource can also include a common time-frequency resource occupied by the second signal, and the first signal is orthogonal to the second signal in the common time-frequency resource.

Dependent claims

A signal sending method, comprising:

determining, by a first terminal, a first signal to be sent;
determining, by the first terminal, a first time-frequency resource, wherein some or all of the first time-frequency resource are second time-frequency resources, and wherein the second time-frequency resource is a time-frequency resource used to send a second signal;
and
sending, by the first terminal, the first signal by using the first time-frequency resource, wherein the first time-frequency resource comprises at least one of the following:
an idle time-frequency resource that is not occupied by the second signal;
or
a common time-frequency resource occupied by the second signal, wherein the first signal is orthogonal to the second signal in the common time-frequency resource, wherein
both the first signal and the second signal are sequence signals, and wherein a third signal is orthogonal to a fourth signal, wherein
the third signal is a part that is of the first signal and that is sent by the first terminal on the common time-frequency resource, and
wherein the fourth signal is a part that is of the second signal and that is sent by a second terminal on the common time-frequency resource.

7 more elements
