Abstract
Embodiments of this disclosure provide an indication information transmission method and an apparatus, and relate to the communications field. The method includes: generating, by a network device, indication information, where the indication information is used to indicate an existence status of a downlink control signal in a first time period; and sending, by the network device, the indication information to a terminal device.
Claims20
A method comprising:
- generating, by a network device, indication information when a downlink control signal needs to be transmitted in a first time period;
- and
- sending, by the network device, the indication information to a terminal device when the downlink control signal needs to be transmitted in the first time period, the indication information indicates the terminal device to listen to the downlink control signal in the first time period, and the network device does not send the indication information when no downlink control signal needs to be transmitted in the first time period, wherein a start location of the first time period is a first time location after a transmission end moment of the indication information, and a length of the first time period is a positive integer and is equal to a quantity of discontinuous reception periods.
A method comprising:
- determining, by a terminal device, whether to listen to a downlink control signal in a first time period according to whether indication information is received;
- and
- listening, by the terminal device, to the downlink control signal in the first time period when the indication information is received by the terminal device, and the terminal device does not listen to the downlink control signal when the indication information is not received by the terminal device, wherein a start location of the first time period is a first time location after a transmission end moment of the indication information, and a length of the first time period is a positive integer and is equal to a quantity of discontinuous reception periods.
A network device comprising:
- a processor;
- and
- a non-transitory computer-readable storage medium storing a program to be executed by the processor, the program including instructions to:
- generate indication information when a downlink control signal needs to be transmitted in a first time period;
- and
- a transceiver configured to send the indication information to a terminal device when the downlink control signal needs to be transmitted in the first time period, the indication information indicates the terminal device to listen to the downlink control signal in the first time period, and the transceiver configured not to send the indication information when no downlink control signal needs to be transmitted in the first time period, wherein a start location of the first time period is a first time location after a transmission end moment of the indication information, and a length of the first time period is a positive integer and is equal to a quantity of discontinuous reception periods.
