1. A transmission method, comprising:
determining, by a network device, a frequency hopping sequence of each of N terminal devices grouped by the network device into G groups in each of L adjacent slots, wherein a length of the frequency hopping sequence is L, any two terminal devices in each group of terminal devices in each slot use a same frequency resource, any two groups of terminal devices in each slot use different frequency resources, and each group of terminal devices in each slot comprises a maximum of K terminal devices, wherein N>2, G≥2, L≥2, 2≤K<N, pilot signals used by each group of terminal devices in each slot are elements in a set that comprises K different pilot signals, and each terminal device in each group in each slot uses a different pilot signal from the set of K different pilot signals in the frequency hopping sequence; and
sending, by the network device, first indication information to a first terminal device in the N terminal devices, wherein the first indication information determines a frequency hopping sequence of the first terminal device and a pilot signal used by the first terminal device in each slot.
