For ease of understanding, some contents involved in the embodiments of the present application are described below:

1. Low power receiver.

The low-power receiver can be called LP-WUR or almost zero power receiver (AZP-WUR). The basic working principle of LP-WUR is that the receiving end includes a first module and a second module. The first module is the main communication module, which is used for sending and receiving mobile communication data, and the second module is a low-power receiving module (also called a low-power wake-up receiving module), which is used to receive the above wake-up signal, as shown in Figure 2. The terminal turns on the low-power receiving module in the energy-saving state to monitor LP-WUS and turns off the main communication module. When downlink data arrives, the network side device will send a wake-up signal to the terminal. After the terminal monitors the wake-up signal through the low-power receiving module, it triggers the main communication module from off to on after a series of judgments, and at this time the low-power receiving module enters the off state from the working state. The low-power wake-up receiving module can be turned on continuously or intermittently, and can receive the low-power wake-up signal when it is turned on.

2. Low power wake up signal (WUS).

In order to reduce the receiving activity of the terminal in the standby state, the RF and baseband (MODEM) modules are truly turned off, thereby greatly reducing the power consumption of communication reception. This can be achieved by introducing a near "zero" power receiver in the receiving module of the terminal. This near "zero" power receiver does not require complex RF module signal detection (such as amplification, filtering, quantization, etc.) and MODEM signal processing, but only relies on passive matching filtering and signal processing with low power consumption.

On the base station side, by triggering a wake-up signal on demand, the near-zero power receiver can be activated to receive the activation notification, thereby triggering a series of processes inside the terminal, such as turning on the RF transceiver and baseband processing modules.

Such wake-up signals are usually some relatively simple on-off keying signals, and the time domain pattern of the on-off keying signal is shown in Figure 3, so that the receiver can obtain the wake-up notification through simple energy detection and subsequent possible sequence detection and recognition processes. In addition, while the terminal turns on the low-power wake-up receiver to receive the wake-up signal, the main receiver module can maintain a low power consumption level, thereby achieving power saving by receiving the wake-up signal.

The reception of the low-power wake-up signal can be applied to a terminal in a Radio Resource Control (RRC) idle (RRC_idle)/inactive (inactive) state, and can also be applied to a terminal in an RRC connected state (RRC_connected), thereby achieving terminal energy saving.

In one embodiment, the wake-up signal mentioned in the present application is the wake-up signal received by the low-power receiver.

3. Beacon signal.

The beacon signal can also be called a low power synchronization signal (Low power-sync signal, LP-SS). The beacon signal is a signal that is sent periodically to transmit time information. The receiving end can obtain time synchronization information by receiving the beacon signal. In some embodiments, mobility measurement or channel measurement can also be performed by receiving the beacon signal. Both Beacon and LP-WUS are received by a low power receiver. In one embodiment, beacon can be regarded as a downlink synchronization signal for LP-WUS reception. In another embodiment, the beacon signal can also be used for terminal mobility measurement, such as cell selection or cell reselection functions. In addition, optionally, the sequence of the beacon signal can have a certain correlation with the LP-WUS sequence. For example, the beacon signal sequence is part of the LP-WUS sequence.

The frequency hopping processing method provided in the embodiment of the present application is described in detail below through some embodiments and their application scenarios in combination with the accompanying drawings.

Referring to FIG. 4 , an embodiment of the present application provides a transmission processing method. As shown in FIG. 4 , the frequency hopping processing method includes:

Step 401, the terminal obtains frequency hopping configuration information of the target signal;

Step 402: the terminal detects the target signal according to the frequency hopping configuration information;

Among them, the target signal includes at least one of a low-power wake-up signal, a low-power synchronization signal, a sequence part of a low-power wake-up signal and a sequence part of a low-power synchronization signal; the frequency hopping configuration information includes at least one of the following: a frequency hopping mode, a frequency hopping start time offset, a frequency hopping start frequency domain offset, a frequency hopping unit and a frequency hopping mode.

In the embodiment of the present application, the frequency hopping configuration information may be partially or entirely agreed upon by the protocol, or may be partially or entirely indicated by the network side device. After the terminal acquires the frequency hopping configuration information of the target signal, the terminal may detect the target signal according to the frequency hopping configuration information of the target signal; or after the frequency hopping configuration information of the target signal is activated, the terminal may detect the target signal according to the frequency hopping configuration information of the target signal.

The terminal of the embodiment of the present application obtains the frequency hopping configuration information of the target signal, and detects the target signal according to the frequency hopping configuration information; wherein the target signal includes at least one of a low-power wake-up signal, a low-power synchronization signal, a sequence part of a low-power wake-up signal, and a sequence part of a low-power synchronization signal; the frequency hopping configuration information includes at least one of the following: a frequency hopping mode, a frequency hopping start time offset, a frequency hopping start frequency domain offset, a frequency hopping unit, and a frequency hopping mode. Therefore, by using the frequency hopping configuration information to detect the target signal, interference on certain frequencies can be resisted and frequency diversity gain can be obtained. Therefore, the embodiment of the present application achieves resistance to frequency domain fading and interference through frequency hopping, thereby improving the reliability of target signal transmission.

Optionally, in some embodiments, the frequency hopping mode includes a first frequency hopping mode, a second frequency hopping mode or a mixed frequency hopping mode, and the mixed frequency hopping mode includes the first frequency hopping mode and the second frequency hopping mode;

Wherein, the first frequency hopping mode is that the frequency position used for transmission is fixed, and the bits represented by at least two frequency points used for transmission are exchanged with each other;

The second frequency hopping mode is to perform frequency hopping on at least two groups of candidate frequency positions.

In the embodiment of the present application, for the first frequency hopping mode, the fixed frequency position for transmission can be understood as the fixed frequency position of the transmitted bit. For example, bit 0 and bit 1 correspond to two frequency positions respectively. The two frequency positions are fixed, and the two frequency positions corresponding to bit 0 and bit 1 can be interchanged.

With respect to the second frequency hopping mode described above, the intervals between different transmission frequency points corresponding to different bits in each group of candidate frequency positions may be fixed or not, and no further limitation is made here.

Optionally, for the hybrid frequency hopping mode, the frequency hopping sequence can be set according to actual needs, and different frequency hopping sequences have different corresponding frequency hopping patterns. For example, in some embodiments, the frequency hopping sequence of the hybrid frequency hopping mode includes any of the following:

Firstly perform frequency hopping according to the first frequency hopping mode, and then perform frequency hopping according to the second frequency hopping mode;

Firstly perform frequency hopping according to the second frequency hopping mode, and then perform frequency hopping according to the first frequency hopping mode;

Frequency hopping is performed simultaneously according to the first frequency hopping mode and the second frequency hopping mode.

It should be noted that the frequency hopping order of the above hybrid frequency hopping method can be agreed upon by the protocol or indicated by the network side device. For example, the network side device can indicate at least one of the radio resource control (RRC) signaling, the medium access control control element (MAC CE) signaling and the downlink control information (DCI) signaling. The indication method can be implicit indication or explicit indication, which is not further limited here.

Optionally, the frequency hopping configuration information can be used to derive a frequency hopping pattern, and the target signal is detected based on the frequency hopping pattern. In some embodiments, the frequency hopping configuration information used to derive the frequency hopping pattern can be agreed upon by the protocol, and the frequency hopping position is derived based on the frequency hopping configuration information agreed upon by the protocol to obtain the frequency hopping pattern. That is, in some embodiments, the frequency hopping pattern can be configured in a manner agreed upon by the protocol.

It should be understood that in the embodiment of the present application, performing frequency hopping according to the first frequency hopping mode and the second frequency hopping mode at the same time means performing frequency hopping of the first frequency hopping mode and the second frequency hopping mode at the same time in one frequency hopping.

Optionally, in some embodiments, the frequency hopping start time offset includes at least one of the following: a frame offset, a subframe offset, a slot offset, and a symbol offset.

In the embodiment of the present application, the frame offset can be understood as a frame-level offset, the subframe offset can be understood as a subframe-level offset, the slot offset can be understood as a slot-level offset, and the symbol offset can be understood as a symbol-level offset. It can be understood that the offset at a certain level refers to an offset whose time unit is a certain level. For example, the frame-level offset refers to an offset whose time unit is a frame.

Optionally, in some embodiments, the method further comprises:

The terminal determines a starting position of frequency hopping according to at least one of the frequency hopping starting time offset and the frequency hopping period.

In the embodiment of the present application, the starting position of the frequency hopping can be understood as the frequency hopping starting time. The above starting position includes at least one of the frequency hopping starting frame position (such as the frequency hopping starting frame number), the frequency hopping starting subframe position (such as the frequency hopping starting subframe number), the frequency hopping starting slot position (such as the frequency hopping starting slot number) and the frequency hopping starting symbol position (such as the frequency hopping starting symbol number).

Optionally, the start frame offset is determined relative to the start position of a frame with a system frame number (SFN) of 0. Optionally, the start subframe position is determined relative to the start position of a start frame.

For example, the frame offset is X, which is equal to 3, and the frequency hopping period is 10 frames, then the frequency hopping start frame of each period is 10*n+X, where n represents the number of periods.

Optionally, since the protocol in the related art has defined the system frame number, the frequency hopping start frame can be determined according to the frame number. Optionally, the start subframe in the start frame is further determined, and optionally, the start slot in the start subframe is further determined, and optionally, the start symbol in the start slot is further determined.

In some embodiments, multiple time offsets may be defined, for example, the frequency hopping start time offset may include a subframe offset and a symbol offset. The subframe number of each periodic frequency hopping start subframe may be determined according to the following formula:

[(system frame number×10)+subframe number] modulo frequency hopping period=subframe offset of the frequency hopping pattern.

Optionally, in some embodiments, the frequency hopping period is the duration of a complete frequency hopping pattern of the target signal or the monitoring period of the target signal.

In the embodiment of the present application, the frequency hopping period is the duration of a complete frequency hopping pattern of the target signal, which can be understood as follows: the time length of the frequency hopping period is equal to the time length of the duration of a complete frequency hopping pattern of the target signal. The frequency hopping period is the monitoring period of the target signal, which can be understood as follows: the frequency hopping period is the same as the monitoring period of the target signal, or the duration of the frequency hopping period is the same as the duration of the monitoring period of the target signal.

Optionally, in an embodiment of the present application, if the frequency hopping is discontinuous under a certain configuration, that is, the reception of the target signal is not continuous (which can be understood as DRX), the frequency hopping period can be understood as the monitoring period of the target signal, such as the monitoring period of LP-WUS or LP-SS.

It should be understood that the value range of the above frequency hopping start time offset is {0～M1-1}, where M1 is the number of unit time occupied by the frequency hopping period (if it is a frame offset, then this unit time is the frame. And so on).

Optionally, in some embodiments, the frequency hopping start frequency domain offset includes at least one of the following: a resource element (RE) offset, a resource block (RB) offset and a subcarrier offset.

In the embodiment of the present application, the above-mentioned RE offset can be understood as an offset at the RE level, the RB offset can be understood as an offset at the RB level, and the subcarrier offset can be understood as an offset at the subcarrier level.

Some understandings about the frequency hopping frequency domain offset can reuse the above explanations about the frequency hopping time offset, which will not be repeated here.

Optionally, in some embodiments, the frequency hopping start frequency domain offset is:

An offset relative to the lowest frequency domain unit or the highest frequency domain unit of the bandwidth occupied by the target signal;

Or, an offset relative to the lowest frequency domain unit or the highest frequency domain unit of a bandwidth part (Bandwidth Part, BWP) where the target signal is located;

Alternatively, an offset relative to a specific reference frequency domain location.

Optionally, the specific reference frequency domain position may be an absolute frequency point A or a common RB0.

Optionally, in some embodiments, the frequency hopping start frequency domain offset is:

An offset of a frequency domain unit occupied by a preset frequency point in a frequency hopping pattern corresponding to the target signal relative to a lowest frequency domain unit or a highest frequency domain unit of a bandwidth occupied by the target signal;

Alternatively, the offset of the frequency domain unit occupied by the preset frequency point in the frequency hopping pattern corresponding to the target signal relative to the lowest frequency domain unit or the highest frequency domain unit of the BWP where the target signal is located.

In the embodiment of the present application, the preset frequency point may be a specific frequency point agreed upon by the protocol or a specific frequency point indicated by the network side device. For example, the preset frequency point may be f0 or f1 in 1-bit FSK modulation, or any one of f0 to f3 in multi-bit FSK modulation.

It should be understood that the value range of the above-mentioned frequency hopping starting frequency domain offset is {0～M2-1}, where M2 is the unit frequency domain occupied by the target signal (if it is a subcarrier offset, then this unit frequency domain is the subcarrier. And so on).

Optionally, the frequency hopping mode includes at least one of the following:

Frequency hopping within the frequency domain bandwidth; can be understood as frequency hopping within a specific frequency domain bandwidth.

Frequency hopping between at least two frequency domain bandwidths.

It should be understood that in the embodiment of the present application, when the frequency hopping mode includes frequency hopping between at least two frequency domain bandwidths, the terminal low-power receiver needs to achieve reception of target signals on multiple frequency domain bandwidths through frequency tuning (retuning).

Optionally, in some embodiments, the frequency hopping unit may include at least one of the following:

at least one bit;

At least one chip.

It can be understood that the above refers to frequency hopping in units of at least one bit or at least one chip.

In the embodiment of the present application, when the frequency hopping unit is one bit, it can be understood that frequency hopping is performed for each bit, that is, frequency hopping is performed with a single bit as a unit.

In the case where the frequency hopping unit includes at least two bits, it can be understood that frequency hopping is performed for multiple bits, that is, frequency hopping is performed in units of multiple bits. For example, frequency hopping is performed in units of sequences. The sequence can be an LP-WUS preamble sequence or an LP-SS preamble sequence. Optionally, a special example of frequency hopping in units of multiple bits is: repetition in units of multiple bits. That is, the multiple bits are repeatedly sent multiple times. For example, the LP-WUS preamble is repeatedly sent twice, and frequency hopping is performed between the two preambles.

When the frequency hopping unit is one chip, it can be understood that frequency hopping is performed for each chip, that is, frequency hopping is performed in units of a single chip. For example, the encoding method used for the target signal is Manchester encoding, where bit ‘1’ is encoded as ‘01’ and bit ‘0’ is encoded as ‘10’. At this time, ‘01’ or ‘10’ contains two chips respectively. In this example, the frequency hopping in units of a single chip refers to frequency hopping between a single chip ‘0’ and a single chip ‘1’.

When the frequency hopping unit is at least two chips, it can be understood as frequency hopping for multiple chips, that is, frequency hopping is performed in units of multiple chips. For example, the target signal adopts Miller coding and M=4, bit ‘1’ is encoded as ‘0011’, and bit ‘0’ is encoded as ‘1100’. In this example, the frequency hopping in units of multiple chips refers to frequency hopping between multiple chips ‘00’ and ‘11’.

Optionally, in some embodiments, the at least one bit includes: at least one of a sequence portion of a target signal, a preamble sequence of a target signal, and a synchronization sequence of a target signal.

In the embodiment of the present application, it can be understood that frequency hopping is performed in units of a sequence of target signals.

Optionally, in some embodiments, a method of acquiring the frequency hopping configuration information of the target signal includes at least one of the following:

Agreement;

Radio Resource Control RRC signaling;

Media Access Control Element MAC CE signaling;

Downlink control information DCI signaling.

In an embodiment of the present application, the method for obtaining the frequency hopping configuration information of the target signal is a protocol agreement, which can be understood as the terminal obtaining the frequency hopping configuration information of the target signal from the information agreed upon in the protocol to generate a corresponding frequency hopping pattern or frequency hopping style. The method for obtaining the frequency hopping configuration information of the target signal is a protocol agreement, which can be understood as RRC, MAC CE signaling or DCI signaling, and can be understood as the frequency hopping configuration information of the target signal indicated by the network side device through RRC, MAC CE signaling or DCI signaling. For example, in some embodiments, DCI can be used to activate/apply one of the multiple frequency hopping patterns configured by the network through RRC signaling. Among them, a frequency hopping pattern is generated correspondingly by a corresponding frequency hopping configuration. Multiple frequency hopping patterns correspond to multiple groups of frequency hopping configurations.

In order to better understand the present application, some examples are provided below for illustration.

Optionally, in some embodiments, it is assumed that the target signal is modulated using 1-bit FSK, that is, two frequencies f0 and f1 are used to represent binary bits '0' and '1' respectively. The following frequency hopping modes are included:

Frequency hopping mode 1: The frequency positions of f0 and f1 are fixed, and frequency hopping is achieved by exchanging f0 for 0 and f1 for 1 so that f0 represents 1 and f1 represents 0. This is shown in Figure 5. In Figure 5, the frequency hopping pattern satisfies:

Adopt frequency hopping mode within the frequency domain bandwidth;

Frequency hopping in single bit units;

The subframe offset of the frequency hopping pattern is shown in FIG5 . The starting frequency offset is calculated relative to the lowest RE number in the bandwidth, that is, the frequency domain starting position of RE0;

For the subframe offset of the frequency hopping pattern, the subframe number of the starting subframe of each periodic frequency hopping can be calculated according to the following formula:

[(system frame number×10)+subframe number] modulo frequency hopping period=subframe offset of the frequency hopping pattern.

According to frequency hopping mode 1, after receiving the bit FSK target signal segment shown in FIG6, the terminal decodes it into a sequence of 1100. In the case of a scheme without frequency hopping, the terminal receives the signal segment shown in FIG6 and decodes it into a sequence of 0110 or 1001.

It should be understood that for a single-frequency/single-carrier FSK waveform, "0" can be represented by two frequencies, and to some extent there can be some frequency graded gain.

Frequency hopping mode 2: frequency hopping is performed at multiple groups of candidate frequency positions, as shown in FIG7 ; further, the intervals between different information transmission frequency points may be fixed (the interval (gap) between f0 and f1 in the figure is fixed) or not fixed.

In FIG5 , there are four groups of candidate frequency positions, namely f0 and f1, f0’ and f1’, f0” and f1”, f0”’ and f1”’. And f0 is fixed to represent 0 and f1 to represent 1. The starting frequency domain offset of the frequency hopping pattern is shown in FIG7 , which is the offset of f1 relative to the starting frequency position of the lowest RE of the bandwidth.

As can be seen from Figure 7, the four candidate frequency positions of f0 are all in the upper half of fc (which can be considered as the center frequency of the bandwidth), and the four candidate frequency positions of f1 are all in the lower half of fc. For a certain receiver filter architecture, it is possible that the four candidate frequencies of f0 are all within the narrowband filter range of terminal f0, and the network side device specifically sends which candidate f0. Since f0 traverses the four candidate frequency positions, it can get some frequency diversity gain.

Frequency hopping mode 3: A mixed frequency hopping mode of mode 1 + mode 2. In addition, the frequency hopping sequence is as follows:

1. Perform frequency hopping in mode 1 first, and then perform frequency hopping in mode 2. The frequency hopping pattern is shown in FIG8 .

2. Perform frequency hopping in mode 2 first, and then perform frequency hopping in mode 1. The frequency hopping pattern is shown in FIG9 .

3. Perform frequency hopping of mode 1 and mode 2 simultaneously, and the frequency hopping pattern is shown in FIG10 .
