[0099] With gradual increase of the subcarrier spacing SCS, in the case where the candidate timing values corresponding to the high SCS for SSSG switching cannot be known, energy saving cannot be performed in the activation phase.

[0100] The method for determining candidate timing values provided in the embodiments of the present disclosure includes the following steps.

[0102] In step S202, the user equipment 101 determines candidate timing values corresponding to a first subcarrier spacing SCS for SSSG switching based on the first SCS; wherein the first SCS is greater than or equal to 240 KHz.

[0103] In some possible implementation manners, the downlink channel is a physical downlink control channel (PDCCH).

[0104] In some possible implementation manners, the first SCS is 240 KHz.

[0105] In some possible implementation manners, the first SCS is 480 KHz.

[0106] In some possible implementation manners, the first SCS is 960 KHz.

[0107] In some possible implementation manners, the first SCS is greater than 960 KHz.

[0108] In some possible embodiments, a maximum value in the candidate timing values is greater than a first value, where the first value is a maximum timing duration corresponding to the second SCS for search space set group (SSSG) switching.

[0109] For example, in a possible example, the second SCS is 120 KHz, and a maximum timing duration corresponding to the second SCS for SSSG switching is 800 slots. The first value is 800 slots. For the case that the first SCS is 480 KHz, a maximum value in candidate timing values corresponding to the first SCS is greater than 800 slots. For the case that the first SCS is 960 KHz, a maximum value in candidate timing values corresponding to the first SCS is greater than 800 slots.

[0110] In some possible embodiments, the maximum value in the candidate timing values is N times of a maximum candidate timing value corresponding to the second SCS.

[0111] In an example, N is 2. In another example, N is 4. In another example, N is 8. In another example, N is 16.

[0112] For example, in a possible example, the second SCS is 120 KHz, and a maximum timing duration corresponding to the second SCS for SSSG switching is 800 slots. For the case that the first SCS is 480 KHz, a maximum value in candidate timing values corresponding to the first SCS can be 1600 slots, 3200 slots, 6400 slots, and the like. For the case that the first SCS is 960 KHz, a maximum value in candidate timing values corresponding to the first SCS can be 1600 slots, 3200 slots, 6400 slots, and the like.

[0113] In some possible embodiments, the candidate timing values include N times of all candidate timing values corresponding to the second SCS, where the second SCS is less than the first SCS.

[0114] In a possible example, a number of candidate timing values corresponding to the first SCS for SSSG switching is the same as a number of candidate timing values corresponding to the second SCS for SSSG switching, and the candidate timing values corresponding to the first SCS for SSSG switching include N times of each candidate timing value corresponding to the second SCS for SSSG switching.

[0115] In some possible embodiments, the candidate timing values include N times of part of candidate timing values corresponding to the second SCS, where the second SCS is less than the first SCS.

[0116] In a possible example, the number of candidate timing values for SSSG switching corresponding to the first SCS is less than the number of candidate timing values for SSSG switching corresponding to the second SCS, and the candidate timing values for SSSG switching corresponding to the first SCS are part of the candidate timing values for SSSG switching corresponding to the second SCS. The candidate timing values for SSSG switching corresponding to the first SCS include N times of part of the candidate timing values for SSSG switching corresponding to the second SCS.

[0117] In a possible example, the candidate timing values for SSSG switching corresponding to the first SCS include 4 times of the candidate timing values for SSSG switching corresponding to the second SCS. The second SCS is 120 KHz, and the first SCS is 480 KHz. The candidate timing values for SSSG switching corresponding to the second SCS include: {1, 2, 3, …, 160, 240, 320, 400, 480, 640, 800}, where the ellipsis represents all values between 4 and 159. The candidate timing values for SSSG switching corresponding to the first SCS can be selected from {4, 8, 12, …, 640, 960, 1280, 1600, 1920, 2560, 3200}, for example, the candidate timing values for SSSG switching corresponding to the first SCS can include {4, 160, 640, 960, 1280, 1600, 2560, 3200}.

[0118] In a possible example, the candidate timing values for SSSG switching corresponding to the first SCS include 8 times of the candidate timing values for SSSG switching corresponding to the second SCS. The second SCS is 120 KHz, and the first SCS is 960 KHz. The candidate timing values for SSSG switching corresponding to the second SCS include: {1, 2, 3, …, 160, 240, 320, 400, 480, 640, 800}, where the ellipsis represents all values between 4 and 159. The candidate timing values for SSSG switching corresponding to the first SCS can be selected from {8, 16, 24, …, 1280, 1920, 2560, 3200, 5120, 6400}, for example, the candidate timing values for SSSG switching corresponding to the first SCS can include {8, 320, 1280, 1920, 2560, 3200, 5120, 6400}.

[0119] In a possible example, the N is a ratio of the first SCS to the second SCS.

[0120] For example, in a possible example, the second SCS is 120 KHz, for the case that the first SCS is 480 KHz, N is 4; for the case that the first SCS is 960 KHz, N is 8.

[0121] In a possible implementation, the candidate timing values corresponding to the first SCS for SSSG switching are the same or different when the first SCS is 480 KHz or 960 KHz.

[0122] In a possible implementation, the network device and the user equipment determine the candidate timing values corresponding to the first SCS for SSSG switching based on the same provision in the protocol based on the first SCS, so that the candidate timing values determined by the network device and the user equipment are the same.

[0123] In the embodiments of the present disclosure, the network device and the user equipment can independently determine the candidate timing values corresponding to the first SCS for SSSG switching based on the first SCS, so that the premise of determining the timing value for listening to the downlink channel is obtained, and after a reasonable timing value for listening to the downlink channel is successfully selected, energy can be effectively saved.

The maximum timing duration corresponding to the SSSG switching for the 120 KHz is 800 slots, and the first value is 800. The maximum value in the candidate timing values corresponding to the first SCS is greater than the first value. For example, in an example, the first SCS is 480 KHz, the candidate timing values corresponding to the SSSG switching for the 480 KHz include {4, 160, 640, 960, 1280, 1600, 2560, 3200}, where the maximum value 3200 in the candidate timing values corresponding to the first SCS is greater than the first value 800, which meets the restriction that the maximum value in the candidate timing values corresponding to the first SCS is greater than the first value.

[0134] In a possible example, the second SCS is 120 KHz, the candidate timing values corresponding to the SSSG switching for the 120 KHz include {1, 2, 3, …, 160, 240, 320, 400, 480, 640, 800}, where the ellipsis represents all values between 4 and 159. The maximum timing duration corresponding to the SSSG switching for the 120 KHz is 800 slots, and the first value is 800. The maximum value in the candidate timing values corresponding to the first SCS is greater than the first value. For example, in an example, the first SCS is 960 KHz, the candidate timing values corresponding to the SSSG switching for the 960 KHz include {8, 320, 1280, 1920, 2560, 3200, 5120, 6400}, where the maximum value 6400 in the candidate timing values corresponding to the first SCS is greater than the first value 800, which meets the restriction that the maximum value in the candidate timing values corresponding to the first SCS is greater than the first value.

[0135] In some possible embodiments, the maximum value in the candidate timing values is N times the maximum candidate timing value corresponding to the second SCS, and the second SCS is less than the first SCS.

[0136] In an example, N is 2. In another example, N is 4. In another example, N is 8. In another example, N is 16.

[0137] For example, in a possible example, the second SCS is 120 KHz, and the maximum timing duration for SSSG switching corresponding to 120 KHz is 800 slots. For the case that the first SCS is 480 KHz, the maximum value in the candidate timing values corresponding to the first SCS can be 1600 slots, 3200 slots, 6400 slots, etc. For the case that the first SCS is 960 KHz, the maximum value in the candidate timing values corresponding to the first SCS can be 1600 slots, 3200 slots, 6400 slots, etc.

[0138] In some possible implementations, the candidate timing values include N times of all candidate timing values corresponding to the second SCS, the second SCS being smaller than the first SCS.

[0139] In a possible example, the number of candidate timing values for SSSG switching corresponding to the first SCS is the same as the number of candidate timing values for SSSG switching corresponding to the second SCS, and the candidate timing values for SSSG switching corresponding to the first SCS include N times of each candidate timing value for SSSG switching corresponding to the second SCS.

[0140] In some possible implementations, the candidate timing values include N times of part of candidate timing values corresponding to the second SCS, the second SCS being smaller than the first SCS.

[0141] In a possible example, the number of candidate timing values for SSSG switching corresponding to the first SCS is smaller than the number of candidate timing values for SSSG switching corresponding to the second SCS, and the candidate timing values for SSSG switching corresponding to the first SCS are part of the candidate timing values for SSSG switching corresponding to the second SCS. The candidate timing values for SSSG switching corresponding to the first SCS include N times of part of the candidate timing values for SSSG switching corresponding to the second SCS.

[0142] In a possible example, the candidate timing value corresponding to the first SCS for SSSG switching includes 4 times of the candidate timing value corresponding to the second SCS for SSSG switching. The second SCS is 120 KHz, and the first SCS is 480 KHz. The candidate timing value corresponding to the second SCS for SSSG switching includes {1, 2, 3, …, 160, 240, 320, 400, 480, 640, 800}, where the ellipsis represents all values between 4 and 159. The candidate timing value corresponding to the first SCS for SSSG switching can be selected from {4, 8, 12, …, 640, 960, 1280, 1600, 1920, 2560, 3200}, for example, the candidate timing value corresponding to the first SCS for SSSG switching can include {4, 160, 640, 960, 1280, 1600, 2560, 3200}.

[0143] In a possible example, the candidate timing value corresponding to the first SCS for SSSG switching includes 8 times of the candidate timing value corresponding to the second SCS for SSSG switching. The second SCS is 120 KHz, and the first SCS is 960 KHz. The candidate timing value corresponding to the second SCS for SSSG switching includes {1, 2, 3, …, 160, 240, 320, 400, 480, 640, 800}, where the ellipsis represents all values between 4 and 159. The candidate timing value corresponding to the first SCS for SSSG switching can be selected from {8, 16, 24, …, 1280, 1920, 2560, 3200, 5120, 6400}, for example, the candidate timing value corresponding to the first SCS for SSSG switching can include {8, 320, 1280, 1920, 2560, 3200, 5120, 6400}.

[0144] In a possible example, N is a ratio of the first SCS to the second SCS.

[0145] For example, in a possible example, the second SCS is 120 KHz, N is 4 for the case that the first SCS is 480 KHz, and N is 8 for the case that the first SCS is 960 KHz.

[0146] In a possible implementation, the candidate timing value corresponding to the first SCS for SSSG switching is the same or different when the first SCS is 480 KHz or 960 KHz.

[0147] In the embodiments of the present disclosure, the network device and the user equipment can independently determine the candidate timing value corresponding to the first SCS for SSSG switching based on the first SCS, thereby obtaining the prerequisite for determining the timing value for listening to the downlink channel, and effectively saving energy after a reasonable timing value for listening to the downlink channel is successfully selected.

[0148] The embodiment of the present disclosure provides a method for determining candidate timing values, which is executed by a user equipment or a network equipment, Figure 4 is a flow chart of a method for determining candidate timing values according to an exemplary embodiment, as shown in Figure 4 The method comprises the following steps:

[0149] In step S401, a first subcarrier spacing SCS is determined based on the first SCS to correspond to a candidate timing value for SSSG switching; the maximum value in the candidate timing value is greater than a first value, and the first value is a maximum timing duration corresponding to a second SCS for search space set group SSSG switching, and the second SCS is less than the first SCS.

[0150] Wherein, the first SCS is greater than or equal to 240KHz

[0151] In a possible example, the second SCS is 120KHz, and the maximum timing duration corresponding to 120KHz for SSSG switching is 800 slots, so the first value is 800. For the case that the first SCS is 480KHz, the maximum value in the candidate timing value corresponding to the first SCS is greater than 800 slots. For the case that the first SCS is 960KHz, the maximum value in the candidate timing value corresponding to the first SCS is greater than 800 slots.

[0152] In a possible example, the second SCS is 60KHz, and the maximum timing duration corresponding to 60KHz for SSSG switching is 400 slots, so the first value is 400. For the case that the first SCS is 480KHz, the maximum value in the candidate timing value corresponding to the first SCS is greater than 400 slots. For the case that the first SCS is 960KHz, the maximum value in the candidate timing value corresponding to the first SCS is greater than 400 slots.

[0153] In a possible example, the second SCS is 120 KHz, and the corresponding candidate timing values for SSSG switching include {1, 2, 3, …, 160, 240, 320, 400, 480, 640, 800}, wherein the ellipsis represents all values between 4 and 159. The maximum timing duration for SSSG switching corresponding to the 120 KHz is 800 slots, and the first value is 800. The maximum value in the candidate timing values for SSSG switching corresponding to the first SCS is greater than the first value. For example, in an example, the first SCS is 480 KHz, and the corresponding candidate timing values for SSSG switching include {4, 160, 640, 960, 1280, 1600, 2560, 3200}. In this example, the maximum value 3200 in the candidate timing values for SSSG switching corresponding to the first SCS is greater than the first value 800, which meets the requirement that the maximum value in the candidate timing values for SSSG switching corresponding to the first SCS is greater than the first value.

[0154] In a possible example, the second SCS is 120 KHz, and the corresponding candidate timing values for SSSG switching include {1, 2, 3, …, 160, 240, 320, 400, 480, 640, 800}, wherein the ellipsis represents all values between 4 and 159. The maximum timing duration for SSSG switching corresponding to the 120 KHz is 800 slots, and the first value is 800. The maximum value in the candidate timing values for SSSG switching corresponding to the first SCS is greater than the first value. For example, in an example, the first SCS is 960 KHz, and the corresponding candidate timing values for SSSG switching include {8, 320, 1280, 1920, 2560, 3200, 5120, 6400}. In this example, the maximum value 6400 in the candidate timing values for SSSG switching corresponding to the first SCS is greater than the first value 800, which meets the requirement that the maximum value in the candidate timing values for SSSG switching corresponding to the first SCS is greater than the first value.

[0158] In some possible implementations, the first SCS is 960 KHz.

[0159] In some possible implementations, the first SCS is greater than 960 KHz.

[0160] Optionally, in some possible embodiments, a maximum value in the candidate timing values is N times of a maximum candidate timing value corresponding to a second SCS, the second SCS being smaller than the first SCS.

[0161] In an example, N is 2. In another example, N is 4. In another example, N is 8. In another example, N is 16.

[0162] For example, in a possible example, the second SCS is 120 KHz, and a maximum timing duration for SSSG switching corresponding to 120 KHz is 800 slots. For the case that the first SCS is 480 KHz, a maximum value in the candidate timing values corresponding to the first SCS can be 1600 slots, 3200 slots, 6400 slots, etc. For the case that the first SCS is 960 KHz, a maximum value in the candidate timing values corresponding to the first SCS can be 1600 slots, 3200 slots, 6400 slots, etc.

[0164] In a possible example, the number of candidate timing values for SSSG switching corresponding to the first SCS is the same as the number of candidate timing values for SSSG switching corresponding to the second SCS, and the candidate timing values for SSSG switching corresponding to the first SCS include N times of each candidate timing value for SSSG switching corresponding to the second SCS.

[0165] In some possible embodiments, the candidate timing values include N times of part of candidate timing values corresponding to a second SCS, the second SCS being smaller than the first SCS.

[0166] In a possible example, the number of candidate timing values for SSSG switching corresponding to the first SCS is smaller than the number of candidate timing values for SSSG switching corresponding to the second SCS, and the candidate timing values for SSSG switching corresponding to the first SCS are part of the candidate timing values for SSSG switching corresponding to the second SCS. The candidate timing values for SSSG switching corresponding to the first SCS include N times of part of the candidate timing values for SSSG switching corresponding to the second SCS.

[0167] In a possible example, the candidate timing values for SSSG switching corresponding to the first SCS include 4 times of the candidate timing values for SSSG switching corresponding to the second SCS. The second SCS is 120 KHz, and the first SCS is 480 KHz. The candidate timing values for SSSG switching corresponding to the second SCS include: {1, 2, 3, …, 160, 240, 320, 400, 480, 640, 800}, where the ellipsis represents all values between 4 and 159. The candidate timing values for SSSG switching corresponding to the first SCS can be selected from {4, 8, 12, …, 640, 960, 1280, 1600, 1920, 2560, 3200}, for example, the candidate timing values for SSSG switching corresponding to the first SCS can include {4, 160, 640, 960, 1280, 1600, 2560, 3200}.

[0168] In a possible example, the candidate timing values for SSSG switching corresponding to the first SCS include 8 times of the candidate timing values for SSSG switching corresponding to the second SCS. The second SCS is 120 KHz, and the first SCS is 960 KHz. The candidate timing values for SSSG switching corresponding to the second SCS include: {1, 2, 3, …, 160, 240, 320, 400, 480, 640, 800}, where the ellipsis represents all values between 4 and 159. The candidate timing values for SSSG switching corresponding to the first SCS can be selected from {8, 16, 24, …, 1280, 1920, 2560, 3200, 5120, 6400}, for example, the candidate timing values for SSSG switching corresponding to the first SCS can include {8, 320, 1280, 1920, 2560, 3200, 5120, 6400}.

[0169] In a possible example, N is a ratio of the first SCS to the second SCS.

[0170] In an example, N is 2. In another example, N is 4. In another example, N is 8. In another example, N is 16.

[0171] For example, in a possible example, the second SCS is 120 KHz, N is 4 for the case that the first SCS is 480 KHz, and N is 8 for the case that the first SCS is 960 KHz.

[0172] Optionally, in a possible implementation, the candidate timing values for SSSG switching corresponding to the first SCS are the same or different when the first SCS is 480 KHz or 960 KHz.

[0173] In the embodiments of the present disclosure, the network device and the user equipment can independently determine the candidate timing value corresponding to the first SCS for SSSG switching based on the first SCS, and the maximum value in the candidate timing value is greater than the maximum timing duration corresponding to the second SCS for SSSG switching, so as to maintain the reasonable rule that the larger the SCS is, the larger the maximum value of the candidate timing value is, thereby obtaining the premise of determining the timing value for listening to the downlink channel, and after a reasonable timing value for listening to the downlink channel is successfully selected, energy can be effectively saved.

[0174] The embodiments of the present disclosure provide a method for determining a candidate timing value, which is executed by a user equipment or a network device, Figure 5 FIG. 6 is a flowchart of a method for determining a candidate timing value according to an example embodiment, as shown in Figure 5 The method comprises the following steps:

[0175] In step S501, a candidate timing value corresponding to a first subcarrier spacing (SCS) for SSSG switching is determined based on the first SCS; and a maximum value in the candidate timing value is N times of a maximum candidate timing value corresponding to a second SCS, and the second SCS is smaller than the first SCS.

[0176] In some possible embodiments, the first SCS is greater than or equal to 240 KHz.

[0177] In some possible embodiments, the second SCS is 120 KHz.

[0178] In some possible embodiments, the second SCS is 60 KHz.

[0179] In some possible embodiments, the downlink channel is a physical downlink control channel (PDCCH).

[0180] In some possible embodiments, the first SCS is 240 KHz.

[0181] In some possible embodiments, the first SCS is 480 KHz.

[0182] In some possible embodiments, the first SCS is 960 KHz.

[0183] In some possible embodiments, the first SCS is greater than 960 KHz.

[0184] In a possible example, the second SCS is 120 KHz, the maximum timing duration corresponding to the second SCS for SSSG switching is 800 time slots, and the candidate timing value corresponding to the first SCS for SSSG switching is N times of 800 time slots. In the embodiments of the present disclosure, the network device and the user equipment can independently determine the candidate timing value corresponding to the first SCS for SSSG switching based on the first SCS, and the maximum value in the candidate timing value is greater than the maximum timing duration corresponding to the second SCS for SSSG switching, so as to maintain the reasonable rule that the larger the SCS is, the larger the maximum value of the candidate timing value is, thereby obtaining the premise of determining the timing value for listening to the downlink channel, and after a reasonable timing value for listening to the downlink channel is successfully selected, energy can be effectively saved.

[0185] In a possible example, the second SCS is 60 KHz, and the maximum timing duration corresponding to the SSSG switching is 400 slots for 120 KHz. The candidate timing values corresponding to the first SCS are N times of 400 slots.

[0186] In an example, N is 2. In another example, N is 4. In another example, N is 8. In another example, N is 16.

[0187] For example, in a possible example, the second SCS is 120 KHz, and the maximum timing duration corresponding to the SSSG switching is 800 slots for 120 KHz. For the first SCS being 480 KHz, the maximum value in the candidate timing values corresponding to the first SCS can be 1600 slots, 3200 slots, 6400 slots, etc. For the first SCS being 960 KHz, the maximum value in the candidate timing values corresponding to the first SCS can be 1600 slots, 3200 slots, 6400 slots, etc.

[0188] For example, in a possible example, the second SCS is 120 KHz, and the candidate timing values corresponding to the SSSG switching include {1, 2, 3, …, 160, 240, 320, 400, 480, 640, 800}, where the ellipsis represents all values between 4 and 159. In this case, for example, the first SCS is 480 KHz, and when N is 4, the maximum value in the candidate timing values corresponding to the first SCS for the SSSG switching can be 3200 slots. For example, the candidate timing values corresponding to the first SCS for the SSSG switching can include {4, 160, 640, 960, 1280, 1600, 2560, 3200}. In some possible implementations, the maximum value in the candidate timing values is greater than a first value, where the first value is the maximum timing duration corresponding to the search space set group (SSSG) switching for the second SCS.

[0189] For example, in a possible example, the second SCS is 120 KHz, and the maximum timing duration corresponding to the SSSG switching is 800 slots for 120 KHz. The first value is 800 slots. For the first SCS being 480 KHz, the maximum value in the candidate timing values corresponding to the first SCS is greater than 800 slots. For the first SCS being 960 KHz, the maximum value in the candidate timing values corresponding to the first SCS is greater than 800 slots.

[0190] In some possible implementations, the candidate timing values include N times of all candidate timing values corresponding to the second SCS, where the second SCS is less than the first SCS.

[0191] In a possible example, the number of candidate timing values for SSSG switching corresponding to the first SCS is the same as the number of candidate timing values for SSSG switching corresponding to the second SCS, and the candidate timing values for SSSG switching corresponding to the first SCS include N times of each of the candidate timing values for SSSG switching corresponding to the second SCS.

[0192] In some possible implementation, the candidate timing values include N times of part of the candidate timing values corresponding to the second SCS, and the second SCS is smaller than the first SCS.

[0193] In a possible example, the number of candidate timing values for SSSG switching corresponding to the first SCS is less than the number of candidate timing values for SSSG switching corresponding to the second SCS, and the candidate timing values for SSSG switching corresponding to the first SCS are part of the candidate timing values for SSSG switching corresponding to the second SCS. The candidate timing values for SSSG switching corresponding to the first SCS include N times of part of the candidate timing values for SSSG switching corresponding to the second SCS.

[0194] In a possible example, the candidate timing values for SSSG switching corresponding to the first SCS include 4 times of the candidate timing values for SSSG switching corresponding to the second SCS. The second SCS is 120 KHz, and the first SCS is 480 KHz. The candidate timing values for SSSG switching corresponding to the second SCS include: {1, 2, 3, …, 160, 240, 320, 400, 480, 640, 800}, in which the ellipsis represents all values between 4 and 159. The candidate timing values for SSSG switching corresponding to the first SCS can be selected from {4, 8, 12, …, 640, 960, 1280, 1600, 1920, 2560, 3200}, for example, the candidate timing values for SSSG switching corresponding to the first SCS can include {4, 160, 640, 960, 1280, 1600, 2560, 3200}.

[0195] In a possible example, the candidate timing values for SSSG switching corresponding to the first SCS include 8 times of the candidate timing values for SSSG switching corresponding to the second SCS. The second SCS is 120 KHz, and the first SCS is 960 KHz. The candidate timing values for SSSG switching corresponding to the second SCS include: {1, 2, 3, …, 160, 240, 320, 400, 480, 640, 800}, where the ellipsis represents all values between 4 and 159. The candidate timing values for SSSG switching corresponding to the first SCS can be selected from {8, 16, 24, …, 1280, 1920, 2560, 3200, 5120, 6400}, for example, the candidate timing values for SSSG switching corresponding to the first SCS can include {8, 320, 1280, 1920, 2560, 3200, 5120, 6400}.

[0196] Optionally, in a possible example, N is a ratio of the first SCS to the second SCS.

[0197] For example, in a possible example, the second SCS is 120 KHz, N is 4 for the case that the first SCS is 480 KHz, and N is 8 for the case that the first SCS is 960 KHz.

[0198] Optionally, in a possible implementation, the candidate timing values corresponding to the first SCS are the same or different when the first SCS is 480 KHz or 960 KHz.

[0199] In the embodiments of the present disclosure, the network device and the user equipment can independently determine the candidate timing values for SSSG switching corresponding to the first SCS based on the first SCS, and the maximum value in the candidate timing values is N times of the maximum candidate timing value corresponding to the second SCS, so that the maximum value of the candidate timing values of the higher SCS and the maximum value of the candidate timing values of the lower SCS meet the multiple relationship, thereby obtaining the premise of determining the timing value for monitoring the downlink channel, and after a reasonable timing value for monitoring the downlink channel is successfully selected, energy can be effectively saved.

The candidate timing values corresponding to the first SCS for SSSG switching can be selected from {4, 8, 12, …, 640, 960, 1280, 1600, 1920, 2560, 3200}, for example, the candidate timing values corresponding to the first SCS for SSSG switching can include {4, 160, 640, 960, 1280, 1600, 2560, 3200}.
