Assignee: GUANGDONG OPPO MOBILE TELECOMMUNICATIONS CORP., LTD.
Field: Digital communication (Electrical engineering)
Classification: CPC H | IPC H

Claim 0:
1. A communication method, comprising:
receiving, by a terminal device, a first signal sent by a network device over an unlicensed spectrum, wherein the first signal is used for indicating that the network device obtains a channel resource of the unlicensed spectrum;
determining, by the terminal device, a first time-domain resource position of a second signal based on the first signal, wherein the second signal is used for indicating information needed to be obtained by the network device for implementing communication with the terminal device by using the channel resource of the unlicensed spectrum, or the second signal is a downlink reference signal; and
receiving, by the terminal device, the second signal sent by the network device over the unlicensed spectrum based on the first time-domain resource position,
wherein the determining, by the terminal device, the first time-domain resource position of the second signal based on the first signal comprises:
determining, by the terminal device, a time slot where the second signal is located based on a symbol position occupied by the first signal in a time slot where the first signal is located,
wherein the determining, by the terminal device, the time slot where the second signal is located based on the symbol position occupied by the first signal in the time slot where the first signal is located comprises:
determining, by the terminal device, a remaining symbol in the time slot where the first signal is located based on the symbol position; and
determining, by the terminal device, the time slot where the second signal is located based on the remaining symbol.
