The information determination method, device, sending end and receiving end provided by the embodiments of the present application will be described in detail below with reference to the accompanying drawings through some embodiments and their application scenarios.

Referring to Figure 2, Figure 2 is one of the flow charts of an information determination method provided by an embodiment of the present application. As shown in Figure 2, the information determination method includes the following steps:

Step 101. The receiving end receives the beacon signal;

Step 102: The receiving end determines the time information of the wake-up signal based on the beacon signal.

In one implementation, the receiving end determines the time information of the wake-up signal based on the beacon signal, which may include at least one of the following:

Determine the time information of the wake-up signal through the configuration information of the beacon signal;

The time information of the wake-up signal is determined through the indication information carried by the beacon signal.

In one implementation, the beacon signal may be used to implicitly indicate relative time information of the wake-up signal.

In one implementation, the receiving end may receive beacon signals periodically.

In one implementation, the beacon signal may be a low-power beacon signal.

In one implementation, the beacon signal may be used to indicate at least one of the following:

The length of the beacon period;

The starting position of the beacon period;

The number of beacon signals included in the beacon cycle;

Time offset within the beacon period;

The length of the beacon signal;

The time interval between adjacent beacon signals within the beacon period;

The identification of the beacon signal within the beacon period;

Identification of beacon period;

Global identification of beacon signals;

Period information of wake-up signal;

Wake-up signal duration information;

First offset information, the first offset information is used to indicate an offset of the wake-up signal relative to the starting position of the reference beacon period.

For example, the beacon signal may indicate the identifier of the beacon period. As a simple example, the wake-up signal may be detected when it is detected that the identifier of the beacon period is the first preset value; or the beacon signal may indicate the beacon period. The identification of the beacon signal within the period, as a simple example, can be detected during When it is detected that the identifier of the beacon signal within the beacon period is the second preset value, the wake-up signal is detected; alternatively, the beacon signal can indicate the identifier of the beacon period and the identifier of the beacon signal within the beacon period, as a simple For example, when it is detected that the identifier of the beacon period is a first preset value and the identifier of the beacon signal within the beacon period is a second preset value, the wake-up signal can be detected; or the beacon signal can indicate a beacon. The starting time position of each beacon signal in each beacon cycle can be determined based on the identity of the beacon cycle and the identity of the beacon signal within the beacon cycle. According to a certain The starting time position of a certain beacon signal within a beacon period determines the moment when the wake-up signal is detected; etc., this embodiment does not limit this.

It should be noted that the beacon signal is a signal that is sent periodically to convey time information. By periodically sending beacon signals to convey time information, low power consumption can be maintained to wake up the receiver, that is, the receiving end is synchronized with the transmitting end. In related technology, the beacon signal can carry a total of 12 bits of information [5:16] among the 64 bits of the sending end's Timer Synchronization Function (TSF) clock (timer). After the receiving end receives the 12 bits of information, , according to the defined time update criteria, update the local TSF timer to achieve synchronization with the sending end. By sending a beacon signal (beacon) to carry the TSF information of the sending end, the receiving end updates the local TSF time according to the received TSF information, so that the TSF time of the receiving end and the sending end are consistent. However, the way of sending beacon to carry TSF information needs to be more complicated. Excessive signaling overhead and large receiver decoding power consumption are not conducive to the actual deployment of large-scale machine communications in the fifth generation mobile communication technology (5th Generation Mobile Communication Technology, 5G).

In this embodiment of the present application, the receiving end may be a terminal. The terminal includes a first module and a second module. The first module is a main communication module and is used to receive communication data transmitted by the sending end and send communication data. The second module is a low-level communication module. The power consumption module, the second module can be used to receive a wake-up signal (also called a low-power wake-up signal) sent by the sending end, and the wake-up signal is used to wake up the main communication module of the receiving end. As shown in Figure 3, the first module is always in a closed state and does not send or receive data when it is not awakened by the second module. When downlink data arrives, the second module detects the wake-up signal sent by the transmitter, and the wake-up signal contains this terminal information, the second module triggers the first module to switch from the closed state to the working state to receive and send data. The second module can be turned on continuously or discontinuously. When turned on, the second module can receive a low-power wake-up signal and a beacon signal (which can also be called a low-power beacon signal).

For example, the terminal may include an LP-WUR receiver. Through the LP-WUR receiver, the The terminal shuts down or sleeps the main communication module under certain circumstances. The terminal uses the LP-WUR receiver to receive a low power wake up signal (LP-WUS) and then turns on the main communication module, which can effectively reduce the cost of the terminal. of power consumption. To further reduce the power consumption of the LP-WUR receiver, discontinuous reception can be used. In the discontinuous reception mode, the DRX parameters of the LP-WUR receiver include the cycle length, starting position and reception time length of the discontinuous reception. The discontinuous reception (Discontinuous reception) of the wake-up signal can be determined based on the beacon signal periodically sent by the transmitter. Reception, DRX) parameters.

In addition, the DRX parameters of the wake-up signal can be configured accordingly based on the main communication link (main radio) information on the network side, or can be determined based on the beacon signal sent periodically for synchronization.

Taking the receiving end as User Equipment (UE) as an example, a DRX cycle is shown in Figure 4. The DRX cycle (cycle) consists of "Duration (On Duration)" and "DRX Off (off)": During the "On Duration" time, the UE monitors the target channel/signal, for example, monitors LP-WUS; during "DRX "off" time, the UE does not monitor the target channel/signal to save power consumption.

In LP-WUR, the beacon signal is also a low-power transmission signal, which may have multiple structural formats and carry multiple configuration information in multiple ways. The configuration information may include the cycle length, the starting position of the cycle and the number of cycles in the current cycle, which provides a possible configuration reference for the DRX cycle configuration information. Therefore, through a certain reference or determination method, DRX can at least determine the time starting position of the wake-up signal based on the beacon signal of LP-WUR.

ΔS _d =ΔX-((floor(n _N /M)-T)·P+ΔS+((n _N modM)-1)·(L+G)).

It should be noted that the unit of the above offset can be the number of subframes, the number of time slots, the number of symbols, or milliseconds, etc.

Therefore, when the first target information and the beacon signal configure or indicate the same information at the same time, the receiving end can comply with the configuration or indication of the beacon signal; or, the receiving end can comply with the configuration or indication of the first target information.

Optionally, the receiving end does not expect that both the beacon signal and the first target information include third target information, and the third target information is used to determine the time information of the wake-up signal.

Example 1:

As shown in Figure 5, define the time starting position of the first beacon period, that is, the starting position of the beacon period is S, the length of the beacon period is P, and the number of beacon signals contained in each beacon period is M, the length of each beacon signal is L, the time interval between adjacent beacon signals within a beacon period, that is, the time interval between adjacent beacon signals within a beacon period is G, and the time interval between adjacent beacon signals within each beacon period is G. The time offset of the time starting position of a beacon signal relative to the time starting position of the beacon period in which the first beacon signal is located, that is, the time offset within the beacon period is ΔS, and the time offset ΔS Can be 0.

The time starting position of the Nth beacon period is (N-1)·P+S, and the time starting position of the nth beacon signal in the Nth beacon period is (N-1)·P +S+ΔS+(n-1)·(L+G).

In one implementation, the process of determining the WUR DRX starting position information based on the starting position S of the beacon cycle can be as follows:

As shown in Figure 6, when the absolute time starting position S of the beacon signal is given or can be determined, that is, the starting position S of the beacon cycle, the receiving end can, based on the starting position S of the beacon cycle, Together with the period length of the beacon period and the identification of the beacon signal within the beacon period, the time of the current receiving detection point is determined. Moreover, according to the identifier T of the reference beacon period and the offset relative to T, that is, the first offset information ΔX, and the starting position S of the beacon period, the absolute starting position of the DRX cycle of the wake-up signal can be directly obtained. . In Figure 6, the reference period T is 1.

The time starting position of the first DRX cycle is: S _d =S+(T-1)·P+ΔX,

The time starting position of the m-th DRX cycle is: S _d =S+(T-1)·P+ΔX+(m-1)· _PD ,

Among them, _PD is the cycle length of DRX of the wake-up signal, and P is the length of the beacon cycle.

In another implementation, the process of determining the starting position information of the wake-up signal DRX based on the offset information may be as follows:

As shown in Figure 7, without a given starting position S of the beacon cycle, the receiving end cannot determine the current accurate time domain and can only determine the relative beacon cycle identification and the beacon cycle based on the beacon signal. According to the identification of the beacon signal, the receiving end can use the offset information to determine how long it will take to reach the wake-up signal DRX cycle, thereby determining the starting position of the wake-up signal DRX. Since the offset information is based on a certain beacon period T as the starting point, and the offset of a certain beacon period T relative to the current receiving detection point can be calculated based on the time information of the beacon signal, the receiving detection The offset between the point and the start of the DRX cycle can be calculated.

It should be noted that the specific calculation method varies according to the information indicated by the beacon signal. Given the identifier of the beacon period and the identifier of the beacon signal within the beacon period, it is relatively simple and can be as follows Calculate the offset of the starting position of the first DRX cycle relative to the current reception detection point:
ΔS _d =ΔX-((NT)·P+ΔS+(n-1)·(L+G)),

Wherein, the offset of the starting position of the first DRX cycle relative to the current reception detection point may be the first offset information ΔX minus the second offset information, and the second offset information is the reference beacon period The starting position information is relative to the offset information of the detected beacon signal, and the second offset information is: (N-T)·P+ΔS+(n-1)·(L+G). In Figure 7, the reference period T is N.

It should be noted that the first offset information may be the difference between the time starting position of the wake-up signal and the time starting position of the reference beacon period, and the second offset information may be the difference between the reception detection point and the reference beacon period. The difference between the time starting position of the wake-up signal and the reception detection point is equal to the difference between the first offset information and the second offset information.

The offset of the starting position of the m-th DRX cycle relative to the current reception detection point can be calculated as follows:
ΔS _d =ΔX-((NT)·P+ΔS+(n-1)·(L+G))+(m-1)· _PD ;

Among them, ΔX is the first offset information, N is the identifier of the beacon period in which the detected beacon signal is located, T is the identifier of the reference beacon period, P is the length of the beacon period, and ΔS is the Time offset, n is the identification of the detected beacon signal, L is the length of the beacon signal, G is the time interval of adjacent beacon signals within the beacon period, P _D is the period length of the wake-up signal, m is positive integer.

Given the global identifier of the beacon signal and the number of beacon signals included in each beacon period, the identifier of the beacon period and the identifier of the beacon signal within the beacon period need to be calculated separately. , convert the identifier of the beacon period and the identifier of the beacon signal within the beacon period.

The offset of the starting position of the first DRX cycle relative to the current reception detection point can be calculated as follows:
ΔS _d =ΔX-((floor(n _N /M)-T)·P+ΔS+((n _N modM)-1)·(L+G)),

The offset of the starting position of the m-th DRX cycle relative to the current reception detection point can be calculated as follows:
ΔS _d =ΔX-((floor(n _N /M)-T)·P+ΔS+((n _N modM)-1)·(L+G))+(m-1)·P _D ,

Among them, ΔX is the first offset information, n _N is the global identifier of the beacon signal, M is the number of beacon signals included in the beacon period, T is the identifier of the reference beacon period, and P is the Length, ΔS is the time offset within the beacon period, L is the length of the beacon signal, G is the time interval between adjacent beacon signals within the beacon period, P _D is the period length of the wake-up signal, and m is a positive integer.
