18 Claims

1. An energy saving signal transmission method, applied to a base station, and the method comprises:

configuring an energy saving signal for a terminal device, wherein the energy saving signal carries energy saving information used to indicate a first configuration of at least one Discontinuous Reception, DRX, cycle to the terminal device, the at least one DRX cycle comprises at least one first cycle and/or at least one second cycle, wherein the first cycle and the second cycle are long cycles and/or short cycles, and the first cycle is different from the second cycle; the first configuration of the DRX cycle comprises at least one of a maximum quantity N of DRX cycles, a maximum quantity K of first cycles or a quantity Y of first cycles, wherein all of N, K and Y are integers greater than or equal to 1;

sending the energy saving signal to the terminal device;

wherein in response to the first configuration of the DRX cycle comprising the maximum quantity N of DRX cycles, the energy saving information is used to indicate at most N DRX cycles after the energy saving signal currently sent by the base station to the terminal device, wherein the at most N DRX cycles comprise at least one first cycle and/or at least one second cycle, a quantity of DRX cycles indicated by the energy saving signal is N1, a quantity of DRX cycles indicated by an energy saving signal previously sent by the base station to the terminal device is N2, N1 and N2 are same with each other or different from each other, N1 is less than or equal to N, and N2 is less than or equal to N;

in response to the first configuration of the DRX cycle comprising the maximum quantity K of first cycles, the energy saving information is used to indicate at most K first cycles after the energy saving signal currently sent by the base station this time; a quantity of DRX cycles indicated by the energy saving signal currently sent is K1, a quantity of DRX cycles indicated by an energy saving signal previously by the base station to the terminal device is K2, K1 and K2are same with each other or different from each other, K1 is less than or equal to K, and K2 is less than or equal to K;

in response to the first configuration of the DRX cycle comprising the quantity Y of first cycles, the energy saving information is used to indicate a configuration of Y first cycles after the energy saving signal currently sent by the base station.
