FIG. 1 shows a method of wireless communication according to an embodiment of the present invention. As shown in Figure 1, method 100 includes:

S110: Receive a target advance indication channel.

It should be noted that, in S110, the target advance indication channel may be a wake-up signal (Wake-up signal, WUS) in an existing communication protocol or the standardization organization is discussing, or a sleep signal (Go-to- sleep signal). Here, the advance indication channel is based on PDCCH, for example, based on a new PDCCH.

In this embodiment of the present invention, optionally, the target advance indicator channel is one of multiple advance indicator channels, and different advance indicator channels among the multiple advance indicator channels have different formats, and the format of the advance indicator channel is defined by At least one of the following parameters represents: DCI format of the advance indicator channel, time-frequency domain resources occupied by the advance indicator channel, repetition times of the advance indicator channel, and aggregation level of the search space of the advance indicator channel. That is to say, the advance indication channels of different formats are different in at least one of the following: DCI format, occupied time-frequency domain resources, repetition times, and aggregation level of the search space. And it can be understood that, since the target advance indication channel is one of various advance indication channels, when the terminal device detects the target advance indication channel, it needs to perform detection in a blind detection manner.

Further, there is a preset correspondence between different parameters used to characterize the format of the target advance indication channel. It can be understood that the preset correspondence between different parameters used to represent the format of the target advance indication channel may be preset by the protocol or configured by the network device to the terminal device. Here, the network device may configure the above-mentioned preset correspondence for the terminal device through a system message.

For example, there is a preset correspondence between the aggregation level of the search space of the target advance indication channel and the number of repetitions of the target advance indication channel, or each aggregation level of the search space of the target advance indication channel corresponds to one or more repeat times. As shown in Table 1, when the aggregation level of the target advance indication channel is 1, the repetition number of the target advance indication channel is 1; when the aggregation level of the target advance indication channel is 2, the repetition number of the target advance indication channel is 10 .

Table 1

Aggregation level of target advance indication channel Number of repetitions of the target advance indication channel 1 1 2 10

Or for another example, there is a preset correspondence between the DCI format of the target advance indicator channel and the repetition times of the target advance indicator channel, or each DCI format of the target advance indicator channel corresponds to one or more repetition times. As shown in Table 2, the DCI format of the target advance indication channel is 1, and the repetition number of the target advance indication channel is 1;

Or for another example, there is a preset correspondence between the DCI format of the target advance indicator channel and the aggregation level of the target advance indicator channel, or each DCI format of the target advance indicator channel corresponds to one or more aggregation levels. For example, the DCI format of the target advance indicator channel is 1, and the aggregation level of the target advance indicator channel is 1 CCE (ControlChannel Element); the DCI format of the target advance indicator channel is 2, and the aggregation level of the target advance indicator channel is 2 CCEs ( Control Channel Element).

Table 2

DCI format of target advance indicator channel Number of repetitions of the target advance indication channel 1 1 2 10

In this embodiment of the present invention, optionally, the terminal device determines the maximum number of repetitions or the maximum duration (MaximumDuration) of the advance indication channel according to the system message/Msg4 message/RRC message/DCI/MAC CE sent by the network device. Or the maximum number of repetitions of the advance indication channel and Rmax (the maximum number of repetitions of the user-specific PDCCH) have a corresponding relationship, and the terminal device can obtain the maximum number of repetitions of the advance indication channel according to Rmax and the corresponding relationship.

Further, the actual number of repetitions or the actual duration (ActualDuration) of the advance indication channels of different terminal equipment can be notified to the terminal equipment by the network equipment through a system message/Msg4 message/RRC message/DCI/MAC CE, etc. The above-mentioned message sent determines the actual number of repetitions or the actual duration of the advance indication channel. Or the actual number of repetitions of the advance indication channel has a corresponding relationship with R (the actual number of repetitions of the user-specific PDCCH), and the terminal device can obtain the actual number of repetitions of the advance indication channel according to R and the corresponding relationship. Alternatively, the terminal device detects the advance indication channel by means of blind detection, so as to determine the actual number of repetitions or the actual duration of the advance indication channel.

S120, when the target advance indicator channel indicates to perform PDCCH monitoring on the target physical downlink control channel, determine the format of the target PDCCH according to the target advance indicator channel, where the target PDCCH is a PDCCH related to the target advance indicator channel .

It should be noted that the target PDCCH is the PDCCH related to the target advance indication channel, and it can be understood that the target PDCCH is the PDCCH that the terminal device needs to monitor for the latest time when the target advance indicator channel instructs the terminal device to perform the operation of monitoring the PDCCH. The start or end time of the target advance indication channel and the preset time interval are calculated to obtain the start time of the related PDCCH. The preset time interval is the time interval between the start or end time of the target advance indication channel and the start time of the relevant PDCCH. The target PDCCH here may be the paging Paging PDCCH or other PDCCHs except the Paging PDCCH.

It should also be noted that, if the target advance indication signal indicates to perform dormancy, the terminal device continues to dormant and does not monitor the target PDCCH.

It can be understood that, after the terminal device determines the format of the target PDCCH according to the target advance indication channel in S120, it can monitor the target PDCCH according to the format of the target PDCCH.

Optionally, in some embodiments, the content transmitted by the target early indication channel includes indication information for indicating the behavior of the target early indication channel. For example, 1 bit (Bit) may be used to carry the indication information. When the value of this bit is 1, the target advance indication channel indicates PDCCH monitoring, and when the bit is 0, the target advance indication channel indicates dormancy.

Optionally, in some other embodiments, the network device and the terminal device agree in advance or the network device informs the terminal device of the following rules through signaling: if the network device sends a target advance indication channel to the terminal device, it means that the target advance indicator channel indicates that the PDCCH monitoring, otherwise (for example, the target advance indication channel is not sent), it means that the target advance indication channel instructs to perform dormancy. In this case, if the terminal device receives the target advance indication channel, it is determined that PDCCH monitoring is required, otherwise it is determined that sleep is required.

Optionally, in some embodiments, there is a correspondence between the format of the advance indication channel and the indicated behavior. Alternatively, it can be understood that the advance indication channel in one format indicates PDCCH monitoring, and the advance indication channel in another format indicates dormancy. In this case, when the terminal device determines that the format of the target advance indicator channel is the first format, it determines that the target advance indicator channel indicates to perform target PDCCH monitoring; the terminal device determines that the format of the target advance indicator channel is as follows: In the second format, it is determined that the target advance indication channel indicates to perform dormancy.

For example, as shown in Table 3, the DCI format of the target advance indication channel corresponds to the DCI format of the target PDCCH. In Table 3, when the DCI format of the target advance indicator channel is 1, the DCI format of the target PDCCH is 3, or when the DCI format of the target advance indicator channel is 2, the DCI format of the target PDCCH is 4.
