Abstract
The present disclosure discloses an example communication method and device. One example communication method includes detecting first downlink control information (DCI) by a terminal device. It is determined, by the terminal device and based on a detection result of the first DCI, whether to receive a reference signal, where the reference signal is used by the terminal device to perform time and frequency synchronization with a network device, and the detection result of the first DCI is further used to indicate whether to detect a first downlink control channel within a first time period.
Claims20
A communication method, comprising:
- detecting, by a terminal device, first downlink control information (DCI);
- and
- determining, by the terminal device based on a detection result of the first DCI, whether to receive a reference signal, wherein the reference signal is used by the terminal device to perform time and frequency synchronization with a network device, and wherein the detection result of the first DCI is further used to indicate whether to detect a first downlink control channel within a first time period.
A communication method, comprising:
- determining, by a network device, an association relationship between first downlink control information (DCI) and a reference signal, wherein the reference signal is used by a terminal device to perform time and frequency synchronization with the network device, and wherein a sending result of the first DCI is used to indicate whether to detect a first downlink control channel within a first time period;
- and
- sending, by the network device, a first message to the terminal device, wherein the first message is used to indicate the association relationship.
A communication device, comprising:
- a transceiver;
- one or more processors;
- and
- a non-transitory computer readable medium storing a program to be executed by the one or more processors, wherein the program comprises instructions that cause the communication device to perform operations comprising:
- detecting, by the transceiver, first downlink control information (DCI);
- and
- determining, based on a detection result of the first DCI, whether to receive a reference signal, wherein the reference signal is used by a terminal device to perform time and frequency synchronization with a network device, and wherein the detection result of the first DCI is further used to indicate whether to detect a first downlink control channel within a first time period.
