Fig. 1 illustrates a method of wireless communication according to one embodiment of the invention. As shown in fig. 1, the method 100 includes:

It should be noted that the target advance indication channel in S110 may be a Wake-up signal (WUS) in the existing communication protocol or in the discussion of the standardization organization or a sleep signal (Go-to-sleep signal) in the existing communication protocol. The early indication channel is based on PDCCH, e.g. on a new PDCCH.

In this embodiment of the present invention, optionally, the target early indication channel is one of multiple early indication channels, different ones of the multiple early indication channels have different formats, and the format of the early indication channel is characterized by at least one of the following parameters: indicating the DCI format of the channel in advance, indicating the time-frequency domain resources occupied by the channel in advance, indicating the repetition times of the channel in advance, and indicating the aggregation level of the search space of the channel in advance. That is, different formats of the early indication channels differ by at least one of: DCI format, occupied time-frequency domain resource, repetition times and aggregation level of search space. And it can be understood that, since the target early indication channel is one of multiple early indication channels, the terminal device needs to perform detection in a blind detection manner when detecting the target early indication channel.

Further, different parameters for characterizing the format of the target early indication channel have a preset corresponding relationship. It is understood that the preset correspondence between different parameters for characterizing the format of the target early indication channel may be preset by a protocol or configured by the network device to the terminal device. Here, the network device may configure the preset correspondence for the terminal device through the system message.

For example, the aggregation level of the search space of the target early indicator channel has a preset correspondence with the repetition number of the target early indicator channel, or each aggregation level of the search space of the target early indicator channel corresponds to one or more repetition numbers. As shown in table 1, when the aggregation level of the target early indicator channel is 1, the number of repetitions of the target early indicator channel is 1; when the aggregation level of the target early indication channel is 2, the repetition number of the target early indication channel is 10.

TABLE 1

2	10

Or for another example, the DCI format of the target early indication channel and the repetition number of the target early indication channel have a preset correspondence, or each DCI format of the target early indication channel corresponds to one or more repetition numbers. As shown in table 2, the DCI format of the target early indicator channel is 1, and the repetition number of the target early indicator channel is 1; the DCI format of the target advance indicator channel is 2, and the number of repetitions of the target advance indicator channel is 2.

Or for another example, the DCI format of the target early indication channel and the aggregation level of the target early indication channel have a preset correspondence, or each DCI format of the target early indication channel corresponds to one or more aggregation levels. For example, the DCI format of the target early indication channel is 1, and the aggregation level of the target early indication channel is 1cce (control channel element); the DCI format of the target early indication Channel is 2, and the aggregation level of the target early indication Channel is 2 cces (control Channel element).

In the embodiment of the present invention, optionally, the terminal device determines the maximum repetition number or the maximum duration (maximum duration) of the advanced indicator channel according to the system message/Msg 4 message/RRC message/DCI/MAC CE and the like sent by the network device. Or the maximum repetition number of the early indication channel and Rmax (the maximum repetition number of the user-specific PDCCH) have a corresponding relationship, and the terminal device can obtain the maximum repetition number of the early indication channel according to Rmax and the corresponding relationship.

Further, the actual repetition times or the actual duration (actual duration) of the advanced indicator channel of different terminal devices may be notified to the terminal device by the network device through a system message/Msg 4 message/RRC message/DCI/MAC CE, etc., and the terminal device determines the actual repetition times or the actual duration of the advanced indicator channel according to the received message sent by the network device. Or the actual repetition number of the early indication channel and the R (the actual repetition number of the user-specific PDCCH) have a corresponding relation, and the terminal equipment can obtain the actual repetition number of the early indication channel according to the R and the corresponding relation. Or the terminal equipment detects the advanced indication channel in a blind detection mode, so as to determine the actual repetition times or the actual duration of the advanced indication channel.

S120, when the target advanced indication channel indicates to monitor a target Physical Downlink Control Channel (PDCCH), determining the format of the target PDCCH according to the target advanced indication channel, wherein the target PDCCH is a PDCCH related to the target advanced indication channel.

It should be noted that, when the target PDCCH is a PDCCH related to the target early indication channel, it may be understood that the target PDCCH is a PDCCH that the terminal device needs to monitor last when the target early indication channel indicates the terminal device to perform an operation of monitoring the PDCCH, for example, a start time of the related PDCCH is calculated according to a start or end time of the target early indication channel and a preset time interval. The preset time interval is the time interval from the starting or ending time of the target advanced indication channel to the starting time of the related PDCCH. The target PDCCH here may be a Paging PDCCH or a PDCCH other than the Paging PDCCH.

It should be further noted that, if the target advance indication signal indicates to perform the sleep, the terminal device continues to perform the sleep and does not perform the monitoring of 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, the terminal device may 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 comprises indication information for indicating the target-early-indication channel behavior. For example, 1Bit (Bit) may be used to carry the indication information, where the target-early-indication channel indicates to perform PDCCH monitoring when the value of the Bit is 1, and the target-early-indication channel indicates to perform sleep when the value of the Bit is 0.

Optionally, in 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 equipment sends the target early indication channel to the terminal equipment, the target early indication channel indicates to perform PDCCH monitoring, otherwise (for example, the target early indication channel is not sent), the target early indication channel indicates to perform dormancy. In this case, if the terminal device receives the target early 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 early indication channel and the behavior of the indication. Or it can be understood that the early indication channel of one format indicates PDCCH monitoring and the early indication channel of another format indicates sleep. In this case, when determining that the format of the target advanced indication channel is the first format, the terminal device determines that the target advanced indication channel indicates to perform target PDCCH monitoring; and when the terminal equipment determines that the format of the target early indication channel is the second format, determining that the target early indication channel indicates to sleep.
