Therefore, some symbols in the WUS data field are copied and placed in front of the original WUS data to form a new structure, namely the first data field and the second data field. , the receiving end (terminal) detects the second data field based on the first data field.

Embodiment 2

In one solution, the WUS signal adopts the OOK modulation method. At this time, the first data field is a specific value with a determined length, where an takes a value of 0 or 1, an comes from a specific set, and the specific set is {0,1}.

Assuming that the length of the second data field is 100 symbols, the specific value length is determined by one of the following methods:

1) The network configuration or protocol predefines 5 symbols.

2) The length of the second data field is different by N1 times, where N1=1/10, that is, the length of the specific value is 10 symbols.

3) The length of the second data field differs by N2 symbols, where N2=80, that is, the length of the specific value is 20 symbols.

Taking the above 2) as an example, if the specific value is 10 symbols in length and consists of 0 and 1, then the specific value can be 0101010101.

Embodiment 3

Detect WUS data based on the information of a certain downlink signal, taking the beacon signal as an example.

In one solution, as shown in Figure 7, a beacon signal (beacon signal) is sent periodically. The structure contains two parts: a preamble and a data field. The first information is inserted into the data field to indicate the detection of the WUS signal. .

In another solution, the beacon signal does not explicitly indicate the first information through the data field, but binds the first information to the type of the beacon signal in a predefined manner, that is, an implicit indication, and the terminal determines the received The beacon signal can detect the corresponding low-power wake-up signal.

In one solution, as shown in Figure 8, the beacon signal is sent according to a fixed period, and the WUS signal period or on-demand send. Among them, beacon signal 1 and beacon signal 2 are detected successfully, beacon signal 3 fails to be detected, and WUS signal 1 and WUS signal 2 are sent on demand. WUS signal 1 and WUS signal 2 respectively correspond to two methods for the terminal to demodulate the third signal based on the first information of the second signal.

Method 1: After the first information is parsed successfully, the first information is directly used to detect the third signal. Because the beacon signal 1 is successfully demodulated, the first information carried in the beacon signal 1 can be used to directly detect the WUS signal 1 when detecting the WUS signal 1 .

Method 2: After the second signal reception fails and/or the first information parsing fails, the third signal is detected using the historical first information. Since the demodulation of beacon signal 3 fails and the first information content cannot be obtained, the first information at the historical moment is used at this time, that is, the detection of WUS signal 2 depends on the first information in beacon signal 2, or the first information of beacon signal 1 and beacon signal 2 are comprehensively considered, and finally WUS signal 2 is jointly detected.
