For a better understanding of the embodiments of the present application, a wake-up related technique is first introduced.

In a wireless communication system, most of the energy of a terminal device is wasted in channel monitoring, i.e. when the terminal device does not have messaging, a lot of energy is consumed if the terminal device continuously monitors the channel. In order to reduce the energy waste, the terminal device may be put in a sleep state, but the sleep state is too long, which increases the information processing/transmission delay, and thus the terminal device must be able to operate in a low power consumption, low delay state. The WUR architecture has been developed, and the core idea is: the terminal device comprises a wake-up receiver section in addition to the conventional primary communication receiver. The main communication receiver is normally closed, the wake-up receiver is utilized to detect paging messages or wake-up information from other devices, and when the wake-up receiver detects the paging messages or the wake-up information which need to wake up the main communication receiver for data communication, the main communication receiver is awakened to communicate with the other devices. The wake-up receiver may be referred to as a low power receiver (Lower power receiver, LPR), or as a low power wake-up receiver (Low power wake up receiver, LPWUR), or as a low power wireless device (also referred to as LPR), or as a low power wake-up wireless device (Low power wake up radio, also referred to as LPWUR), there is no substantial difference in using the radio or receiver concepts for the wake-up device since the wake-up radio has only receive functionality. The wake-up receiver has very low resident power consumption, so that the effect of saving the power consumption of the terminal equipment can be achieved.

In order to reduce power consumption, the modulation scheme corresponding to the wake-up information received by the wake-up receiver is generally relatively simple, for example, on-Off Keying (OOK) which indicates the value of the bit information by whether to send a signal, for example, on indicates that the value of the bit information is "1", off indicates that the value of the bit information is "0", or vice versa. Thus, the receiver can identify the signal only through simple envelope detection, and complex baseband processing is not needed.

For a low data rate scene, the bit information is coded into 1010 by a value of 1, the pulse pattern after the OOK modulation is coded into 0101 by a value of 0, the pulse pattern after the OOK modulation is coded into OFF-ON-OFF-ON by a value of 0101, and the symbol duration after each modulation is 4us, then each bit information is transmitted by 4 OOK symbols, namely 16 us; for a high data rate scene, the bit information is coded to be 10 by a value of 1, the pulse pattern after the OOK modulation is correspondingly ON-OFF, the bit information is coded to be 01 by a value of 0, the pattern after the OOK modulation is correspondingly OFF-ON, and each modulated symbol has a duration of 2us, so that each bit information is transmitted by 4 us. In a communication system, spectrum resources are very precious, and information for WUR is an OOK signal, taking the above high-rate scenario as an example, when the wake-up bandwidth occupies 4MHz, the wake-up bit rate is at most 1bit/16 us=250 kbps, the spectrum efficiency is 1bit/16us/4 mhz=0.0156 bit/s/Hz, so low data information is transmitted by using precious spectrum, and the spectrum use efficiency is reduced.

In view of this, as shown in fig. 3, the present application proposes a method 300 of transmitting information, the method 300 comprising:

in step S310, the first device determines pattern information indicating whether a pulse is transmitted on each of N time units during the first period, and also indicating wake-up information of the second device.

Specifically, the pattern information indicates that a pulse is transmitted over K time units among N time units in the first period, and that no pulse is transmitted over the remaining N-K time units in the first period. The K time units may be continuous or discrete. One or more time units corresponding to one continuous pulse may be used, for example, one pulse may correspond to 2 time units, and the transmission energy is greater than 0 in each of the 2 time units, or one pulse may correspond to more time units. Likewise, the non-pulsing time units may be continuous or discrete.

The pattern information is formed by pattern information of each time unit in the N time units, the pattern information is ON/OFF pattern information, wherein the ON/OFF pattern information of the ith time unit in the N time units is ON, the first device is represented to send a pulse in the ith time unit, the ON/OFF pattern information of the ith time unit is OFF, the first device is represented to not send a pulse in the ith time unit, and i is a positive integer less than or equal to N. Whether to transmit a pulse can also be understood as whether the transmitted energy is 0, when the transmitted energy is greater than 0, it means to transmit a pulse, and when the transmitted energy is equal to 0, it means to not transmit a pulse. For example, the pattern information is ON OFF ON, and the pattern information indicates a pulse condition over n=4 time units, where the first device transmits a pulse over the first, third, and fourth time units and the first device does not transmit a pulse over the second time unit.

Alternatively, whether a pulse is transmitted on each of the N time units during the first period may be understood as whether the first device transmits the first signal on each time unit.

Optionally, the K time units corresponding to the pulses are K first time units, the N-K time units without the pulses are N-K second time units, and the difference between the first time units and the second time units includes at least one of the following:

the first time unit has data/signaling/reference signal transmission, and the second time unit has no data/signaling/reference signal transmission;

the first time unit is an OFDM symbol with energy transmission, and the second time unit is an OFDM symbol without energy transmission;

the receiving device may detect that the energy is above a certain threshold value in the time unit, and the receiving device does not detect that the energy is above a certain threshold value in the second time unit;

the first device has a higher energy at the first time unit than the second time unit, or

The first device has an energy above a first threshold value for a first time unit and an energy below a second threshold value for a second time unit, the first threshold value may be the same or different from the second threshold value.

Specifically, the first device determines style information according to whether to wake up the second device. For example, when the first device needs to wake up the second device, the style information is determined to be style information a, the first device transmits a pulse on a time unit in which the style information a indicates to transmit a pulse, and does not transmit a pulse on a time unit in which the style information a indicates to not transmit a pulse.

The process of determining style information by the first device may specifically include:

1) The first equipment determines wake-up information of the second equipment according to whether the second equipment is to be woken up, wherein the wake-up information of the second equipment is a bit sequence;

2) The first equipment determines style information according to the wake-up information and a pulse modulation mode of the wake-up information; the pulse modulation mode of the wake-up information indicates the corresponding relation between the bit value in the bit sequence and the ON/OFF pattern information of at least one time unit in the N time units, wherein ON indicates to send pulses and OFF indicates not to send pulses.

The wake-up information pulse modulation mode may indicate a correspondence between the bit sequence value and the ON/OFF pattern information. The different bit information may be represented by the width, position, amplitude size or a combination thereof of the pulses, essentially how the information is expressed in pulses as agreed between the network device and the terminal device. Fig. 4 shows several ways of pulsing.

Mode 1: the presence or absence of a pulse is used to indicate different information, for example, binary bit "1" is used to indicate ON, binary bit "0" is used to indicate OFF, or vice versa, i.e., binary bit "0" is used to indicate ON, and binary bit "1" is used to indicate OFF. Fig. 4 (a) is a schematic diagram showing information when the time unit is 1 time unit.

Mode 2: the different information is represented by the width of the pulses. For example, a binary bit "00" is represented by no pulse transmitted for 4 time units, i.e., bit "00" is represented by OFF-OFF, and a binary bit "01" is represented by 1 time unit for the pulse width, i.e., bit "01" is represented by ON-OFF; the binary bit "10" is represented by a pulse width of 2 time units, i.e., the bit "10" is represented by ON-OFF, and one pulse corresponds to two time units in the time domain, i.e., the pulse width is 2 time units; the binary bit "11" is represented by a pulse width of 3 time units, i.e., bit "11" is represented by ON-OFF, as shown in fig. 4 (b). If all OFF is considered to be a pulse width of 0, mode 1 can also be considered as a special form of mode 2.

Mode 3: the different information is represented by the position of the pulse, e.g. an ON pulse preceded by a binary bit "1", an OFF pulse preceded by a "0", and vice versa. As shown in fig. 4 (c), the information indicating schematic diagram of the ON pulse width of 1 time unit is 2 time units in length. As another example, as shown in (d) of fig. 4, binary bit "00" is represented by the first time cell of the ON pulse among the four time cells, binary bit "01" is represented by the second time cell of the ON pulse among the four time cells, binary bit "10" is represented by the third time cell of the ON pulse among the four time cells, and binary bit "11" is represented by the fourth time cell of the ON pulse among the four time cells.

Mode 4: the different information is represented by a combination of the position and the width of the pulse. For example, as shown in FIG. 4 (e), bit "00" is represented by ON-OFF-OFF-and bit "01" is represented by ON-ON-OFF-OFF, bit "10" is represented by OFF-OFF-ON-ON, and bit "11" is represented by OFF-OFF-OFF-ON.

Mode 5: different information is represented by different amplitudes of the pulse, for example binary bit 00 by a pulse amplitude of 0.25, 0.5 of 01, 0.75 of 10, and 1 of binary bit 11 as shown in fig. 4 (f). A pulse amplitude of 0 can be used to represent information, so mode 1 can also be seen as a form of pulse amplitude modulation.

The time unit is a unit representing a time length, specifically, one time unit may be an orthogonal frequency division multiplexing (orthogonal frequency division multiplexing, OFDM) symbol, or a half OFDM symbol, or 1/4 OFDM symbol, one time unit may further include an OFDM symbol and a Cyclic Prefix (CP) corresponding to the OFDM symbol, or the length of one time unit is denoted as n×tc, where Tc is a time unit, and its value may be related to an OFDM subcarrier spacing Δf and a number of fast fourier transform (fast Fourier transform, FFT) points n_f, for example T _C ＝1/(Δf·N _f ) For example, Δf is 480khz, n—f=4096. Alternatively, Δf is 312.5khz and n—f=64. The length of a time cell can also be expressed in absolute time, for example 1 time cell length of 1 microsecond. The embodiment of the application does not limit the representation method and the length of the time unit.

In step S320, the first device transmits style information to the third device, and the third device receives style information from the first device.

And the third device determines which time units in the first period can receive the information from the first device according to the received style information, receives the information in the corresponding time units, and does not receive the information in the time units without pulse transmission indicated by the style information, so that the information receiving efficiency is effectively improved, and the energy waste caused by the information receiving in the time units without signal transmission is avoided.

The first period may be a time period predefined by the protocol, for example directly defining the start time and the end time of the first period, or predefining the start time and the duration of the first period; or the first period may be indicated by signaling sent by the first device, for example, by RRC signaling to indicate the starting time and duration of the first period, and optionally, may further indicate a period corresponding to the first period.

S320 is an optional step. For example, the first device may not send the pattern information to the third device, and at this time, the third device may perform signal reception in each of the N time units in the first period, and reject the symbol with low energy/poor signal quality of the received signal according to the energy and/or signal quality of the received signal. This way, signaling of the first device to send the style information to the third device may be saved.

In step S330, the first device sends first signals to the second device and the third device over K time units, where the K time units belong to N time units, and the K time units are time units of which the pattern information indicates a transmission pulse, and the first signals are used to carry reference signals and/or data information sent to the third device, where N, K are positive integers, and K is less than or equal to N.

The first device transmits power 0 over N-K time units, where the N-K time units belong to N time units of the first period and the N-K time units are time units for which pattern information indicates that no pulse is transmitted.

The first device transmits a first signal on a time unit of which the pattern information indicates a transmission pulse, the first signal being used to carry reference signals and/or data information transmitted to the third device. Wherein the reference signals comprise at least one of channel state information reference signals (channel state information reference signal, CSI-RS) for measuring channel state information and positioning reference signals (positioning reference signal, PRS) for positioning, the data information comprising user data information and/or control signaling.

It will be appreciated that the first device described above transmits the first signal to the second device and the third device, and that the first device does not transmit the first signal to the second device and the third device, respectively. Instead, the first device sends the first signal, and both the second device and the third device attempt to receive. And performing subsequent processing according to the received signal.

In step S340, the third device receives the first signal.

When the first device sends the style information to the third device, the third device receives the first signal from the first device on K time units in N time units according to the style information, and acquires the reference signal and/or the data information from the first device according to the first signal.

When step S320 is an optional step, the first device does not transmit the pattern information to the third device, the third device determines which time unit the first device transmitted the first signal and which time unit the first device did not transmit the first signal according to the energy level and/or the signal quality of the received signal for each of the N time units, and receives the first signal from the first device at those time units determined to have transmitted the first signal, and acquires the reference signal and/or the data information of the third device according to the first signal.

When the reference signal is included in the information carried by the first signal, the reference signal may include at least one of CSI-RS, PRS. For example, if the reference signal is a CSI-RS, the third device may make channel state measurements over part or all of the K time units of the first period, i.e. the third device may make measurements with the reference signal in the first signal while receiving the first signal. If the reference signal is a PRS, the third device may make positioning measurements over some or all of the K time units during the first period. In performing positioning measurement, it is necessary to obtain an arrival time, an arrival angle, and the like of radio waves for measuring a terminal position. In general, signals from multiple cells need to be acquired to obtain location information.

Further, since there are no pulses transmitted over N-K time units in the N time units in the first period, the third device may perform interference measurement, or be configured to avoid interference to other devices over some or all of the N-K time units.

In step S350, the second device determines whether to wake up according to the pulse received from the first device.

The second device may also be referred to as a wake-up device, which may also be referred to as a WUR device.

It will be appreciated that for the second device, the pulse is the first signal from the first device.

The second device receives a pulse from the first device at a wake-up information receiver, wherein the wake-up information receiver comprises a first period. The wake-up signal receiver may include M time units, the first period includes N time units, M is greater than or equal to N, and whether a pulse is received on N time units among the M time units of the wake-up signal receiver is used to indicate the pattern information. Alternatively, the second device receives pulses from the first device over N time units of the first period, and whether a pulse is received over each of the N time units of the first period is used to indicate the pattern information. It is understood that the wake-up information receiver may be referred to as a wake-up information transmitter on the first device side, and the first signal receiver may be referred to as a first signal transmitter on the first device side.

And the second device determines whether to wake up according to the style information.

The second device determines pattern information according to the reception conditions of the pulses over the N time units of the first period, thereby determining whether to wake up the device. When the second device detects an energy signal in one of the N time units, or the detected power in the time unit is greater than 0, or the received energy in the time unit is greater than a threshold, the second device considers that a pulse is received in the time unit, thereby determining that the ON/OFF pattern information corresponding to the time unit is ON. Similarly, when the second device does not detect the energy signal in the time unit, or the detected power in the time unit is equal to 0, or the first signal is not received in the time unit, or the received energy in the time unit is smaller than a threshold value, the second device considers that the pulse is not received in the time unit, thereby determining that the corresponding ON/OFF pattern information is OFF. The second device may determine ON/OFF pattern information of each time unit over the N time units of the first period one by one, thereby determining pattern information, and further determining whether to wake up.

For example, when n=4, the second device receives the pulse in the first time unit and the third time unit of 4 time units, and does not receive the pulse in the second time unit and the fourth time unit, the pattern information is ON-OFF-ON-OFF, and the second device further determines whether to wake up according to the ON-OFF-ON-OFF pattern information. By way of example, the manner of determining whether to wake up may include the following.

In one mode, the second device determines whether to wake up according to the style information. The corresponding relation between the first device and the second device, namely between the network device and the terminal device, can be agreed in advance between the style information and whether to wake up. For example, the style information includes style information a and style information B, which correspond to the wake-up device and the non-wake-up device respectively, and when the second device determines that the style information is style information a according to the received pulse condition, the second device wakes up the device; and when the second device determines that the style information is style information B according to the received pulse condition, the second device does not wake up the device. For example, when the predefined ON-OFF-ON-OFF pattern represents a wake-up device, the second device determines that the pattern information is ON-OFF-ON-OFF according to the condition of the pulse received from the first device, the second device determines to wake up the device. There may be more style information in addition to style information a and style information B.

Through the corresponding relation between the pattern information and the wake-up time, the second device can determine whether to wake-up only by receiving the information in the first period and determining the ON/OFF patterns corresponding to each time unit ON N time units in the first period.

In a second mode, the second device determines wake-up information according to the style information, and the second device determines whether to wake up according to the wake-up information.

In this manner, the second terminal device determines wake-up information according to the style information, including:

the wake-up information is a bit sequence, and the second device determines the wake-up information according to the pattern information and a pulse modulation mode of the wake-up information, wherein the pulse modulation mode indicates a corresponding relation between a bit value in the bit sequence and an ON/OFF pattern of at least one time unit of the N time units. Referring to fig. 4, after the second device determines the pattern information, that is, after a series of ON-OFF patterns (patterns) are determined, a binary bit sequence corresponding to the pattern information may be determined according to a pulse modulation manner, and the determined bit sequence is wake-up information of the second device.

For example, when the second device determines that the pattern information is ON-OFF-ON-OFF using the modulation scheme shown in fig. 4 (a), it determines that the wake-up information is "1010". When the second device determines that the pattern information is ON-OFF-ON-OFF using the modulation scheme shown in fig. 4 (c), it determines that the wake-up information is "01". As exemplified above by n=4, the number N of time units in the actual first period is not limited, nor is the length of the corresponding bit sequence, nor is the modulation scheme.

The composition and structure of the wake-up information is described below.

The wake-up information is composed of wake-up data information; or the wake-up information is composed of wake-up data information and wake-up synchronization information.

Wherein the wake-up data information comprises wake-up message content, the wake-up data information further comprising at least one of: and waking up the area identifier, waking up the cell identifier and checking the cyclic redundancy code.

The following describes information included in the wake-up data information:

wake-up area identification: may also be referred to as WUR zone identification, for indicating that the wake device may reside in a WUR state without waking the mobile zone of the master device. When the WUR device detects a new WUR region identity, it is considered that the WUR device moves out of the previously camped WUR region, at which point the primary radio is awakened and cell reselection is enabled. As shown in fig. 5, cell 1, cell 2, cell 3 constitute one WUR region 1, cell 4, cell 5, and cell 6 constitute another WUR region 2. When WUR device moves from WUR region 1 to WUR region 2, the primary radio needs to be awakened for cell reselection.

Wake-up cell identity: which may also be referred to as WUR cell identification, is used to indicate the cell served by the primary device that wakes up the device. When the WUR device detects a new WUR cell, it is considered that the WUR device moves out of the previously camped WUR cell, at which point the primary radio can be awakened and cell reselection can be performed.

Wake-up message content: also known as WUR wake up information, information indicating wake up. Specifically, the value in table 1 may be one. Wherein if it is indicated that the first device does not wake up any device at the wake-up information reception time, a certain sequence agreed in advance, for example, sequence 1, may be employed, or it may be indicated that it is not wake up by other content than a specific identification. E.g. not any of cell identity, group identity, device identity, it means not to wake up.

TABLE 1

For another example, the wake-up message content may be one of the values in table 2. Wherein, the wake-up device is represented by sequence 2, and the wake-up device is represented by sequence 1 or any other content other than sequence 2.

TABLE 2

Information content	Meaning of
		Sequence 1/non-sequence 2	Not awakening
Sequence 2	Arousal

A counter: and the counter is increased by 1 each time the first device system information is updated, and returns to 0 after being counted to the maximum value. The counter may be used by WUR devices to determine whether the first device updated the system message. A change in the counter is detected indicating that the primary radio is to be awakened to receive the system message. The counter may be changed only when system information related to the configuration information of the wake-up device is updated, and other system message changes do not require the counter to be updated, thus saving power by the second device.

Cyclic redundancy check, CRC: for verifying the aforementioned information. The number of check bits of the CRC can be determined according to the amount of wakeup information transmission information, wakeup information transmission reliability requirements, and the like. For example, the number of bits of the CRC may be 6, 11, 16, or 24 bits. The CRC is calculated in detail in section 38.212 vg.7.0.5.1 of the 3GPP protocol.

The wake-up information can be only composed of wake-up data information, the wake-up data information can only comprise wake-up information content, at the moment, the synchronous and wake-up functions can be realized by directly using a sequence corresponding to the wake-up information content, and the wake-up equipment realizes the synchronous function by detecting the data information which is agreed in advance.

The wake-up synchronization information includes a synchronization signal, which may enable the second device, i.e. the wake-up device, to find the start time of the WUR, avoiding false detection. The wake-up synchronization information may be a synchronization sequence, and the synchronization sequence may be designed as a fixed sequence, so that the detection complexity may be reduced.

For example, the synchronization information may be a predetermined sequence, for example, the synchronization sequence {0101, 1011, 0100, 0100,1110,1000,1100, 0111}, the WUR device may first detect the synchronization sequence, and if the synchronization signal sequence energy is found to be lower than a certain threshold, the WUR device may be considered to move out of the wake-up area, thereby automatically waking up the master device.

When the wake-up information is composed of wake-up data information and wake-up synchronization information, the wake-up data information and the wake-up synchronization information may be respectively modulated by different pulse modulation methods, for example, the wake-up synchronization information may be modulated by a modulation method as shown in fig. 4 (a), the wake-up data information may be modulated by a modulation method as shown in fig. 4 (c), or the wake-up data information and the wake-up synchronization information may be modulated by the same pulse modulation method, for example, both modulated by a modulation method as shown in fig. 4 (a).

Optionally, the information in the wake-up information may be repeated, for example, the wake-up synchronization information may include a repeated synchronization sequence, and by repeating transmission, the reliability of information reception may be improved. When the wake-up information is a bit sequence, the bit sequence may also be repeated, for example, when the wake-up information is a bit sequence of "0110", the 4 bits may be extended, for example, each bit may be repeated to obtain "00,11,11,00", or each bit may be inverted to obtain "01,10,10,01", or a sequence may be repeated, for example, a sequence may be repeated to obtain "0110,0110", or a sequence may be inverted to obtain "0110,1001". In the above description, 4 bits are taken as an example, and the bits in the actual wake-up information may be greater than 4 bits or less than 4 bits, which is not limited in this application. After receiving the pulse, the wake-up device may combine and resume the wake-up information according to predefined rules. Through the design, the coverage performance can be effectively improved, and the transmission reliability is improved.

Fig. 6A-6D illustrate several examples of compositions for wake-up information. In the following example, the subcarrier spacing Δf=2 ^μ ·15[kHz]。

Case a. As shown in fig. 6A, in one example, the first period is 1ms, taking μ=4, that is, the subcarrier spacing Δf=240 kHz, with an extended CP defined by 3GPP 38.211V g.7.0, there is a symbol in 1msAnd if the ON-OFF pattern pair of two symbols can transmit 1 bit of information, one ON/OFF pattern is called one ON/OFF pattern pair, 96 ON/OFF pattern pairs can be provided in 1ms, 96 bits of information can be transmitted in 1ms, wherein the wake-up synchronization information is 32 bits, and the WUR area identifier, the WUR cell identifier, the wake-up message content and the CRC occupy 16 bits respectively. The pulse width can be reduced by adopting larger subcarrier spacingThe time of each bit of information is less, so as to improve the transmission efficiency, and an extended CP is adopted, on one hand, in order to reduce the complexity of wake-up information reception, because the length of the first symbol is different from the length of other symbols in each time slot when a Normal CP is defined by 3GPP 38.211V g.7.0, on the other hand, the length of the extended CP is greater than that of the Normal CP, and the coverage can be improved by adopting the extended CP relative to the Normal CP, because a longer CP can support larger delay spread when the long CP is used for sensing.

Case b. In one example, the first period is 1ms, taking μ=3, i.e. the subcarrier spacing Δf=120 kHz, with extended CP, the first period is 1ms, then 1m is withinEach symbol, two symbols transfer 1 bit of information, in the above figure, one ON/OFF waveform is called one ON/OFF pattern pair, and 48 ON/OFF pattern pairs can be provided in total in 1ms, so that 48 bits of information can be transmitted in 1ms, wherein WUR cell identification and wake-up message content occupy 16 bits respectively, a counter occupies 4 bits, and a CRC occupies 12 bits. In this exemplary system, we do not carry wake-up synchronization information during the wake-up information time, but use WUR cell identification to double as a synchronization function. This design contains a counter that is incremented by 1 each time the first device system information is updated. The counter may be used by WUR devices to determine whether the first device updated the system message. Upon detecting a change in the counter, the primary radio is awakened to receive the system message. One specific WUR format implementation method shown in this application is shown in fig. 6B.

Case c. In one example, the first period is 1ms, taking μ=2, i.e. the subcarrier spacing Δf=60 kHz, with extended CP, the first period is 1ms, then 1m is within Each symbol, two symbols, conveys 1 bit of information, and one ON/OFF waveform in the above figure is called one ON/OFF pattern pair, and there can be 24 ON/OFF pattern pairs in 1 ms. Only the content of the wake-up message is sent, the content of the wake-up message is a 24-bit long sequence, and the sequence takes the sequence1 denotes wake-up, and fetch sequence 2 denotes no wake-up. One specific WUR format implementation method shown in this application is shown in fig. 6C.

Case d. in one example, the first period is 1ms, taking μ=2, i.e. the subcarrier spacing Δf=60 kHz, with extended CP, the first period is 1ms, then 1m is withinEach symbol, two symbols, conveys 1 bit of information, and one ON/OFF waveform in the above figure is called one ON/OFF pattern pair, and there can be 24 ON/OFF pattern pairs in 1 ms. The wake-up message content is represented by 20 bits and the counter is carried by 4 bits. The wake-up message content and the counter function as described above. One specific WUR format implementation method shown in this application is shown in fig. 6D.

By the method, the first device transmits the reference signal and/or the data signal to the third device, and meanwhile, the first device transmits the wake-up information to the second device, the second device determines whether to wake-up according to the receiving condition (pattern) of the first signal, the third device acquires the reference signal and/or the data information according to the first signal, and further uses the reference signal to perform processes such as sensing measurement or acquire the data information carried in the first signal, so that the service efficiency of a frequency spectrum is effectively improved in the system, and the integration of sensing and wake-up and the integration of communication and wake-up are realized.

The present application also provides a method 400 for transmitting signals, as shown in fig. 7, the method 400 includes:

in step S410.1, the first device sends wake-up information configuration information to the second device. Correspondingly, the second device receives wake-up information configuration information.

The wake-up information configuration information is used to indicate a wake-up information receiver (wake up oppotunity), the wake-up information configuration information comprising time domain information of the wake-up information receiver and/or frequency domain information of the wake-up information receiver, the time domain information of the wake-up information receiver comprising a start time of the wake-up information receiver, a period of the wake-up information receiver, and a duration of the wake-up information receiver.

As described with reference to fig. 8, the wake-up information configuration information indicates a start time and a duration of wake-up information in each period, and a period of a wake-up information receiver opportunity. The second device, i.e., the wake-up device, may calculate a start time and an end time of the wake-up information receiver in each period according to the wake-up information configuration information.

It will be appreciated that the wake-up information receiver may also be referred to as a wake-up information transmission opportunity for the second device, i.e. an opportunity for the first device to transmit wake-up information to the second device.

In step S410.2, the first device sends first signal configuration information to the third device. Correspondingly, the third device receives the first signal configuration information.

The first signal configuration information is used for indicating a first signal receiver, the first signal configuration information comprises time domain information of the first signal receiver and/or frequency domain information of a first signal transmission period, and the time information of the first signal receiver comprises starting time of the first signal receiver, period of the first signal receiver and duration of the first signal receiver.

As also described with reference to fig. 7, the third device may determine the start time and duration and the corresponding period according to the first signal configuration information. So that the start and end times of the first signal in each period can be determined.

Optionally, when the first signal receiver indicated by the first signal configuration information and the wake-up information receiver indicated by the wake-up information configuration information overlap completely in the time domain within a certain period, that is, the start time and the end time of the first signal receiver are the same, and the start time and the end time of the first period are the same as the start time and the end time of the wake-up information and the first signal. When the first signal reception opportunity start time is not exactly the same as the wake-up information reception opportunity start time, as shown in fig. 9, the first period is included in the first signal reception opportunity duration, the first period includes N time units, the first signal reception opportunity duration is P time units, N is smaller than P, the first device also transmits the first signal, or a part of the first signal, to the third device over P-N time units among the P time units, and the third device starts to receive the first signal at the first signal reception opportunity start time indicated by the first signal configuration information, and the reception period includes N time units of the first period, that is, it can be understood that the first signal transmitted in the first period is a part of the first signal transmitted from the first device to the third device. The third device determines the first signal based on the received information over P time units, determines reference information and/or data information. Similarly, as shown in fig. 9, when the duration of the wake-up information receiver is M time units, where M is greater than N, that is, in one period, the wake-up information receiver completely includes N time units in the first period, the first device may also determine whether to send a pulse on each time unit according to whether to wake up the second device on other M-N time units in the M time units, and the second device may determine whether to wake up according to the overall pulse receiving condition on the M time units.

The first period is an overlapping portion of the time domain resource of the at least one wake-up information receiver and the time domain resource of the at least one first signal receiver. Alternatively, the first period may be an overlapping portion of the time domain resource in at least one period of the wake-up information receiver and the time domain resource in at least one period of the first signal receiver.

Optionally, the first period is also periodic, the period of which corresponds to the period of the first signal receiver opportunity. Therefore, when the period of the wake-up information receiver is an integer multiple of the period of the first signal receiver, the position of the first period with respect to the wake-up information receiver is the same for the second device, i.e., the wake-up device, in the different periods of the wake-up information, and the position of the first period with respect to the first signal receiver is the same for the third device in the different periods of the first signal.

Referring to fig. 9, when the wake-up information receiver in one wake-up period overlaps with the first signal receiver in one first signal receiver period in the time domain, the overlapping portion in the time domain is a first period, which includes N time units.

The first period overlaps or partially overlaps with the time domain resources of the at least one wake-up information receiver, and the first period overlaps or partially overlaps with the time domain resources of the at least one first signal receiver. Or it may be understood that the first period overlaps wholly or partly with the time domain resources in at least one period of the first signal receiver opportunity and the first period overlaps wholly or partly with the time domain resources in at least one period of the wake-up information receiver opportunity. When all three overlap, namely, the duration of the wake-up information receiver is equal to the duration of the first signal receiver in the wake-up period, the two durations are equal to N time units, the starting time of the wake-up information receiver is equal to the starting time of the first signal receiver, and the ending time of the wake-up information receiver is equal to the ending time of the first signal receiver. The first period is periodic and has the same period as the period of the first signal.

Optionally, the period of the wake-up information receiver is an integer multiple of the period of the first signal receiver. If the period corresponding to the wake-up information is the first period, the period corresponding to the first signal is the second period, and the first period may be an integer multiple of the second period. That is, the interval of the wake-up information is longer than the interval of the reference signal and/or the data signal, thereby reducing the resource occupation corresponding to the wake-up information.

As shown in fig. 10, the wake-up information reception opportunity period of the second device (e.g., UEA) is an integer multiple of the first signal reception opportunity period of the third device, and the wake-up information reception opportunity of the UEA overlaps with the first signal reception opportunity in the time domain during the first signal reception opportunity period, and the overlapping portion is the first period. In the second first signal receiver period, the wake-up information receiver of the fifth device (e.g., ue b) overlaps with the first signal receiver in the time domain, and at this time, the overlapping portion of the two may also be referred to as a first period, and the ue b may receive the pulse from the first device during this first period, and determine whether to wake-up according to the reception situation.

Therefore, when the wake-up information period of one terminal device is an integer multiple of the first signal period of other terminal devices, a plurality of wake-up devices can be introduced, and in the periods of different first signals, whether different wake-up devices wake-up or not can be indicated, so that the utilization rate of the system spectrum is further improved.

It will be appreciated that the first signal receiver opportunity may also be referred to as a first signal transmission opportunity for the third device, i.e. an opportunity for the first device to transmit the first signal to the third device.

The frequency domain information of the wake-up information receiver indicates a first frequency domain bandwidth occupied by the wake-up information, and the frequency domain information of the first signal receiver indicates a second frequency domain bandwidth occupied by the first signal, wherein the first frequency domain bandwidth is smaller than or equal to the second frequency domain bandwidth, and the second frequency domain bandwidth is smaller than or equal to the system bandwidth. The bandwidth corresponding to the first signal is larger than the bandwidth corresponding to the wake-up information, so that the receiving precision of the first signal can be improved, for example, the sensing precision is improved, the bandwidth corresponding to the wake-up information is narrower, and the power consumption can be reduced.

As shown in fig. 11, the second frequency domain bandwidth occupied by the first signal may be an integer multiple of the first frequency domain bandwidth occupied by the wake-up information. The relevant wake-up information of the plurality of wake-up devices may be informed within the frequency band of the first signal. The frequency domain resource may be expressed by a position of a start frequency and a perceived signal Bandwidth, or may be expressed by a position of a center frequency and a perceived Bandwidth, or may be expressed by a position of a start frequency and a position of an end frequency, or the first device may divide the system Bandwidth into several sub-channels (sub-channels) or Bandwidth parts (Bandwidth parts), expressed by sub-channel numbers (sub-channel index) or Bandwidth Part numbers (Bandwidth Part Index).

Step S410.3, the first device sends interference measurement configuration information to the second device;

the fourth device receives interference measurement configuration information from the first device, the interference measurement configuration information being used for indicating interference measurement period configuration information, the interference measurement period configuration information comprising time information of an interference measurement period and/or frequency domain information of the interference measurement period, the time information of the interference measurement period comprising a start time of the interference measurement period, a period of the interference measurement period, and a duration of the interference measurement period.

Step S420.0 the first device determines a first period.

In one embodiment, the first device determines a wake-up information receiver opportunity of the second device based on wake-up information configuration information of the second device. The first device determines a first signal receiver opportunity of the third device according to the first signal configuration information of the third device. When the first signal receiver of the third device overlaps or partially overlaps with the wake-up information receiver of the second device in the time domain, the first device further determines a first period according to the wake-up information receiver of the second device and the first signal receiver of the third device, where the first period is an overlapping part of the wake-up information receiver of the second device and the first signal receiver of the third device in the time domain. Optionally, the frequency domain portion of the first signal transmitted during the first period is a frequency domain overlapping portion of the second device wake-up information receiver with the first signal receiver of the third device. In a specific embodiment, the wake-up information receiver may be M time units, where the first period is N time units, and M is greater than or equal to N.

In one embodiment, the first device determines a wake-up information receiver opportunity of the second device based on wake-up information configuration information of the second device. The first device determines an interference measurement period of the fourth device according to the interference measurement period configuration information of the fourth device. When the interference measurement period of the fourth device overlaps or partially overlaps with the wake-up information receiver of the second device in the time domain, the first device further determines a first period according to the wake-up information receiver of the second device and the interference measurement period of the fourth device, where the first period is a time domain overlapping portion of the wake-up information receiver of the second device and the interference measurement period of the fourth device. The first period is a frequency domain overlapping portion of the second device wake-up information receiver and the first signal receiver of the fourth device in the frequency domain.

Step S420.1, the second device determines a wake-up information receiver;

and the second equipment determines the wake-up information receiving opportunity according to the wake-up information configuration information. The wake-up information receiver may include a first period, but the second device need not determine the first period, the first period being transparent to the wake-up device.

The wake-up information receiver may include a first period, specifically, the first period may overlap with all or part of the time domain resources in at least one period of the wake-up information receiver.

Step S420.2 the third device determines a first signal reception opportunity;

the third device determines a first signal receiving opportunity according to the first signal configuration information, wherein the first signal receiving opportunity comprises a first period; the first signal receiver may comprise a first period, in particular, the first period may overlap entirely or partially with the time domain resource of the first signal receiver in at least one period. When the first period is all overlapping with the first signal receiver opportunity, the first period is equal to the first signal receiver opportunity without additional signaling to the third device. The first signal configuration information is further used to indicate a duration of the first period and a start time of the first period when the first period partially overlaps the first signal receiver.

Specifically, as shown in fig. 9, the first signal configuration information may indicate a start time and an end time of the first period, for example, inform an offset between the start time of the first period and a start time of the first signal receiver, denoted as offset1, and inform an offset between the end time of the first period and the start time of the first signal receiver, denoted as offset2, and the third device may determine the start time and the length of the first period as offset2-offset1 according to the information. Alternatively, the first signal configuration information may notify the offset1 and the length (length) of the first period, that is, N time units, or may complete the indication of the first period.

Alternatively, the indication information of the first period may be sent to the third device through separate signaling, in addition to being carried in the first signal configuration information.

Step S420.2 the fourth device determines an interference measurement period;

the fourth device determines an interference measurement period according to the interference measurement configuration information, wherein the interference measurement period comprises a first period. The interference measurement period comprises a first period, in particular, the first period is fully or partially overlapped with the time domain resources of the interference measurement period in at least one period. Similarly, when the first period is fully overlapped with the first signal receiver, the first period is equal to the interference measurement period. When the first period partially overlaps with the interference measurement period, the interference measurement configuration information may further carry indication information of the first period, and the fourth device determines the first period through the indication. For specific description reference is made to S420.2.

Step S430, the first device determines style information.

And the first device determines wake-up information pattern information of a wake-up information receiver according to the wake-up information, wherein the wake-up information pulse pattern comprises pattern information corresponding to a first period. The step-related description may be referred to as step S310.

The first device determines a pulse transmission pattern in a first period according to the wake-up information.

The pattern information is used to indicate a pulse transmission pattern during the first period when the first period partially overlaps with the wake-up information receiver (see fig. 9 and 10). For example, the duration of the wake-up information receiver is 8 symbols, the wake-up information is 10011010, and the wake-up information pulse pattern is: ON-OFF-ON-OFF, wherein the first symbol to the 6 th symbol are the first period, the pattern information includes only the pulse transmission pattern of the 6 symbols. For example, the pattern information is represented by a bitmap, the burst is represented by "1", and the non-burst is represented by "0", and the bitmap for representing the pattern information at this time is "100110".

And step S440.1, the first device sends the style information to the third device. Accordingly, the third device receives the style information.

And step S440.2, the first device sends the style information to the fourth device. Accordingly, the fourth device receives the style information.

S450, the first device sends first signals on K time units according to the sending mode indicated by the style information in N time units in the first period, and the sending power of the N-K time units is 0.

When the wake-up information receiver overlaps with the first period, one embodiment is: the first device determines wake-up information, and determines wake-up information pattern information corresponding to a wake-up information receiver according to the wake-up information, wherein the wake-up information pattern information indicates whether each of M time units in the wake-up information receiver transmits a pulse or not, and the wake-up information receiver comprises a first period including N time units. The first device transmits a first signal over K of the time units in the transmission manner indicated by the pattern information in N of the time units in the first period, where the transmission power of N-K of the time units is 0. The wake-up information receiver may transmit pulses in the wake-up information pulse pattern at other M-N time units in the first period, transmit pulses with power of 0 at time units marked ON, and transmit pulses at some or all of the M-N time units, and the signals carried by the pulses are not limited herein, and may be data information or other information such as reference signals.

Step S460, the second device determines whether to wake up according to the receiving condition of the first signal or according to the pulse receiving condition.

The second device determines whether to wake up based on the pulse reception situation at the wake up information receiver. When the wake-up information receiver is overlapped with the first period, the second device determines whether to wake up according to the pulse receiving condition in the first period.

When the wake-up information receiver partially overlaps the first period, the second device determines whether to wake up based on the pulse reception situation during the first period and the pulse reception situation outside the first period included in the wake-up information receiver.

And S470, the third device receives the first signal according to the style information.

And S480, the fourth equipment performs interference measurement according to the style information. Specifically, interference measurements are made over some or all of the N-K time units.

In the above described implementation method, the third device and the fourth device are optional in the above described embodiments, that is, may not include steps S410.2, S420.3, S440.1, S470, or steps S410.3, S420.4, S440.2, S480.

It should be understood that the steps described above are merely a specific implementation method, and the steps actually performed are not necessarily strictly in the order listed above.

Optionally, the method may further include, before step S410.1:

The first device receives an enter wake mode request message from the second device, and the enter WUR mode request may further include wake information configuration information suggested by the second device.

The first device sends response information for entering the wake mode to the second device. The wake-up information configuration information may be carried in the wake-up mode response information.

The second device receives the wake-up mode response information of the first device, and if the first device confirms that the second device is authorized to enter the WUR mode, the WUR device is configured according to the response information of the first device, and the WUR mode is entered.

The second device may send a request to enter WUR mode through RRC signaling, for example, by UE assistance information and/or wake-up information configuration information suggested by the second device. The UE auxiliary information is adopted to send the request for entering the WUR mode and/or the wake-up information configuration information suggested by the second equipment, so that the existing protocol can be better compatible.

A specific wake-up device (i.e., a second device) may initiate a request to enter a WUR mode to a serving cell (i.e., a first device) of the primary radio through the primary radio of the wake-up device when it is determined that the low power consumption receiving state is satisfied, where the WUR mode refers to an operation mode in which the device turns off the primary radio and receives wake-up information through the WUR device, where the wake-up device comprehensively considers at least one or more of the following factors to determine whether to enter the low power consumption receiving state:

1) The state in which the device is awake. Preferably, the wake-up device is IN IDLE state, or IN IN-ACTIVE state, more suitable for entering WUR mode

2) The speed of movement of the device is awakened. Preferably, the wake-up device is more adapted to enter WUR mode when in a low speed or stationary state

3) The location of the device in the cell is awakened. Preferably, the wake-up device is more suitable to enter WUR mode when not at the cell edge

4) Traffic to wake up the device. Preferably, the wake-up device has less traffic and is more suitable for entering WUR mode

5) The service quality of service requirement QoS (Quality of service) of the wake-up device is preferably adapted to enter WUR mode when the wake-up device can accept higher delay

6) Power consumption of the device is awakened. Preferably, the wake-up device is more suitable for entering WUR mode when it is in low-medium power.

7) The type of wake-up device. Preferably, a device with a relatively low battery capacity, such as a wearable device or an application type device of the internet of things such as meter reading, is configured, and is more suitable for entering a WUR mode.

Optionally, before determining the wake-up information of the second device, the method further includes:

transmitting at least one of the following identifications to the second device: wake area identification, wake cell identification, wake device group identification.

The process of the first device determining the identity may comprise:

the first device assigns WUR device identification and/or WUR group identification to WUR devices, specifically,

the first step: a WUR is determined to identify a resource pool. The WUR identification resource pool may be determined according to the number of bits of the WUR identification, for example, the bits of the WUR identification are 16 bits, and the first device may determine that all or a part of the 16 bits are the WUR identification resource pool. WUR groups and WUR devices may share one WUR-identified resource pool, or WUR devices and WUR devices may each have a respective resource pool. For example, if the WUR device is identified as 12 bits and the WUR group is identified as 4 bits, the WUR sets the device resource pool to be all or part of the 12 bits and the WUR group resource pool to be all or part of the 4 bits. A portion of the reserved resource pool may be implemented for special purposes, e.g. an identification may be reserved for representing a broadcast group.

And a second step of: an identification allocation WUR device is selected from the WUR identification resource pool that is not used by other devices.

Specifically, there are at least two ways:

mode 1: an unused identifier is randomly selected from the WUR identifier resource pool to be allocated to WUR devices.

Mode 2: the first device determines the identity of the WUR device served by the first device according to WUR identities distributed and used by the neighbor device in the same wake-up information receiving time. For example, if WUR for a neighbor device is identified as 1011,1001,0001, WUR for a first device is identified as 0100,0110,1110, which has the advantage that the interference of the perceived signal can be reduced.

In the case of mode 2, before determining the wake-up information of the second device, the method further includes:

and acquiring wake-up information receiver opportunity configuration of the neighbor equipment, wherein the wake-up information receiver opportunity configuration comprises wake-up information receiver opportunity time configuration information and/or frequency domain configuration information, and acquiring WUR identifications allocated by the neighbor equipment at a wake-up information receiver.

and sending the corresponding relation between the wake-up information and the sequence to the second equipment.

The method for sending the corresponding relation between the wake-up information and the sequence to the second device comprises the following specific implementation steps:

determining a wake-up information format, wherein the wake-up information is composed of wake-up sequences;

the correspondence between wake-up information and wake-up sequences is determined, e.g. sequence 1 indicates wake-up and sequence 2 indicates no wake-up. Alternatively, sequence 1 indicates no wake-up and sequence 2 indicates wake-up.

And sending the corresponding relation between the wake-up information and the sequence to the second equipment. Correspondingly, the second device receives the corresponding relation between the wake-up information and the sequence.

Accordingly, the second device receives the sequence 1 or the sequence 2 at the wake-up information receiver, and determines whether to wake up according to the corresponding relation between the wake-up information and the sequence.

In this implementation method, the first device may configure different wake-up information and sequence correspondence for different wake-up devices, so as to perform interference randomization. Or the first device and the neighbor device respectively configure different corresponding relations of wake-up information and sequences for the wake-up devices respectively served by the first device and the neighbor device so as to avoid interference, namely, avoid interference or conflict generated by information sent on the same or adjacent resources as much as possible.

Alternatively, the fourth device may be the first device, or the third device, or may be another device. The fourth device is optional in embodiments. When the fourth device is the first device, i.e. the network device, S430.3 is not required to be executed, i.e. the interference measurement configuration information is not required to be sent to the fourth device, and the first device performs echo measurement in N-K time units, thereby further improving the spectrum use efficiency of the system.

Optionally, in the embodiments described herein, the receiving device of the content carried by the first signal may not be limited, and/or the content carried by the first signal may not be limited, where the implementing method described herein is a wake-up information sending and receiving method, and the first period is equal to the wake-up information receiving opportunity.

Optionally, when the above method involves multiple cells, in order to further improve the sensing detection performance, inter-cell interference avoidance/avoidance may be further performed between multiple cells supporting the sensing and wake-up integrated design to improve the sensing performance and the wake-up detection performance.

The method comprises the steps of determining a neighbor cell set with interference relation with first equipment, and selecting a cell with strongest interference to the first equipment as a neighbor cell with interference relation with the first equipment, or selecting the first equipment as an interference source to cause interference to other cells as a neighbor cell with interference relation with the first equipment. The device in the neighbor cell set having the interference relationship may also be called a sensing signal when the first signal is a reference signal, where the sensing signal overlaps or partially overlaps with a time-frequency resource of wake-up information reception. Here, the fact that the perceptual signal overlaps or partially overlaps with the wake-up information receiving time-frequency resource means that the perceptual signal overlaps or partially overlaps in the time domain, for example, the overlapping portion is the first period. The frequency bands occupied in the frequency domain are the same or adjacent frequency domain ranges.

And determining the wake-up information transmission contents of devices in the neighbor cell set with interference relationship, so that the number of bits 1 of the value after bit exclusive or of the wake-up signal transmission contents of two cells with the same or adjacent frequency domain and the same time domain resource occupied in the time domain is as large as possible, namely, for the wake-up information conflicting on the resource, the bit sequences of the wake-up information are as different as possible, and signal interference is avoided. For example, two neighbor cells having an interference relationship are respectively cell_i and cell_j, the cell_i cell wake-up signal transmission content sequence is a_i, the cell_j cell wake-up signal transmission content is a_j, a_i and a_j are represented by bits of ON/OFF waveforms of each symbol, the bit 1 is represented by ON, and the bit 0 is represented by OFF. The rule of bit exclusive or can be understood as 01 =1, 0=0, 1=0, 1=0=1. The number of bits 1 in the value after bit exclusive or is as large as possible, and one specific implementation method is that each sequence of the cell_j is a sequence after taking a 'not' for each bit of each sequence of the cell_i. One specific example is shown in table 3. Taking the above 24-bit wake-up message content as an example, if cell_i is used to indicate that bit sequence 1 of no information is {0101, 1011,0100, 0100,1110}, cell_j is used to indicate that bit sequence 1 of no information is {1010, 0100, 1011, 1011, 0001}, if cell identification of cell_i is {1100,0110,1011,0100,1001},

Table 3 neighbor cell wake-up message content

If the number of cells in the neighbor cell set with interference relationship is greater than 2, the specific value of each WUR information of the multiple cells can be determined according to the number of sets and the number of WUR information bits, for example, in the above example, the number of bits of WUR identification is 20 bits, assuming that the number of cells is 3, 4 sequences are required for each cell, and 3×4=12 sequences are involved, and then from any binary sequence with 20 bits, the sequence with the largest code distance between every two of 12 sequences can be selected and allocated to 3 cells respectively. This design may make the possibility that in the same time unit, for example, in a symbol, when the symbol of one cell is ON, the symbol of the other cell is OFF as much as possible, so as to reduce inter-cell interference detected by the sensing signal.

Further, in the WUR information format example, the method further includes a 4-bit counter, so as to minimize perceived interference, we can further construct a 4-bit counter sequence, for example, the content of the counter of the cell_i is an actual value, the content of the counter of the cell_j is a value obtained by taking the actual value as a non-post value according to bits, and 0 is a non-post value of 1. As shown in table 4. The following table exemplifies a counter of 4 bits, and the other counter bit numbers refer to the same rule, namely, when one cell is ON as far as possible, the other cell is OFF so as to reduce inter-cell interference of sensing signal detection.
