Since the base station needs to cover as large an area as possible, the IoT module needs to be able to communicate even when it is far away from the base station, which makes the IoT device still need to consume up to 30mA of current during wireless communication, so the current IoT module It is still necessary to use a battery with a higher capacity to work, which also makes it difficult to make the size of the IoT module small and increases the cost of the IoT device.

In addition, some low-power terminals play an important role in IoT applications such as medical care, smart home, industrial sensors, and wearable devices. However, due to the limited size of such terminals, it is difficult to simply increase the battery capacity to extend the operating time of these devices. Therefore, in order to prolong the battery life of the terminal, it is necessary to reduce the power consumption of wireless communication, among which the radio transceiver is one of the most power-consuming components.

Therefore, in order to further popularize the IoT, it is impossible to use a higher-capacity battery when the IoT module is implanted into the human body or into a smaller object. Instead, it is necessary to use a smaller battery or even completely get rid of the battery limitation, or Design a method to reduce the power consumption of radio transceivers to overcome the cost, size, power consumption and other limitations of IoT devices.

At present, according to the power-saving mode operation of the wireless LAN standard IEEE 802.11 defined by the Institute of Electrical and Electronics Engineers (IEEE), after the terminal device enters the sleep state, it needs to wake up periodically to receive control information from the AP , according to the indication carried in the control information (such as traffic indication map (traffic indication ma, TIM)), the terminal device can perceive whether there is downlink data from the AP. If the terminal device is in the dormant state for a long time, it can enjoy lower power consumption, but it will increase the delay of receiving data. In order to achieve a balance between power efficiency and data reception delay for battery-driven terminal equipment, the IEEE 802.11TGba organization was established and developed a draft of IEEE 802.11ba (also known as wake-up radio).

The goal of IEEE 802.11ba WUR is to enable active devices that consume less than 1mW. To this end, the terminal equipment is equipped with two radio chains, the primary connection radio (PCR) (also known as the primary receiver) and the companion connection radio (Companion Radio) (also known as the wake-up receiver (WUR) ). Among them, the PCR consumes a lot of power, and it is expected to switch to sleep mode for as long as possible, thereby significantly reducing power consumption; the WUR consumes less power, and is used to monitor the wake-up frame sent by the AP, and perform PCR after the wake-up frame is detected. wake.

As shown in FIG. 2 a , a main receiver 211 and a wake-up receiver 212 are deployed in the receiver device 210 . When the transmitting end device 220 (such as AP or terminal device) is not sending data, the main receiver is turned off, also known as being in a dormant state, and the wake-up receiver is turned on; as shown in FIG. 2b, when the transmitting end device 220 sends data, first Send wake-up data (such as the above-mentioned wake-up frame), and the receiving end device 210 activates the main receiver 212 after receiving the wake-up data through the wake-up receiver 211, so that the main receiver is turned on, also known as being in an active state. At this time, the receiving end device 210 passes The main receiver 211 receives the data sent by the transmitter device 220 after waking up the data.

It should be noted that the information bits of the wake-up machine are modulated into on-off keying (OOK) symbols, and the transmitter device uses these OOK symbols to shield the generated narrowband orthogonal frequency division multiplexing (OFDM) ) waveform (that is, OOK waveform), so as to further optimize the OOK waveform. The OOK symbol is carried on 13 subcarriers. It is called in the wireless local area network standard IEEE 802.11ba defined by the Institute of Electrical and Electronics Engineers (IEEE). Multicarrier (multicarrier, MC) OOK. On the receiving end device side, OOK demodulation does not require any channel equalization in the frequency domain and time domain, so the receiving end device listens by waking up the receiver for non-coherent detection (such as envelope detection). With non-coherent detection, the receiver device does not need to maintain/track the oscillation rate with high precision. Therefore, a phase-locked loop can be avoided, further reducing power consumption at the receiving side.

It should be understood that the OOK symbol is only an example of the WUR wake-up frame, and does not constitute any limitation to the present application.

Based on this, in June 2021, 3GPP discussed the Internet of Things enhancement technology in the R18 potential research direction seminar organized by 3GPP, and disclosed that 5G evolution (5G-Advanced) will start from R18 and introduce WUR in the 5G NR system. However, when the WUR technology is applied in the NR system, how does the wake-up receiver determine the frequency domain resources for receiving the wake-up signal (such as the above-mentioned wake-up frame), in other words, which frequency domain resources the wake-up receiver monitors for the wake-up signal, currently, Effective solutions are lacking.

In view of the above problems, the embodiment of the present application provides a solution for determining frequency domain resources, so that a wake-up signal sender (such as a network device or a terminal device) and a wake-up receiver can transmit a wake-up signal on the determined frequency domain resources.

In order to facilitate the understanding of the embodiments of the present application, the terms involved in the present application are briefly described first.

1. Parameter set (numerology): In the NR system, in order to adapt to OFDM waveforms with different subcarrier spacings, a parameter set is introduced so that the subcarrier spacing is not limited and can be adapted according to different usage scenarios.

The transmission parameter sets supported by the NR system are shown in Table 1 below:

Table 1

Wherein, Δf is the subcarrier spacing, and μ is an integer greater than or equal to 0.

2. Antenna port: An antenna port is defined such that the channel of one symbol transmitted on that antenna port can be inferred from the channel of another symbol transmitted on the same antenna port, in other words, the experience of different signals transmitted on the same antenna port The channel environment is the same.

3. Resource grid (resource grid) or resource grid: a resource grid corresponds to a parameter set and carrier, the resource grid includes

subcarriers and

OFDM symbols, where,

Indicates the number of resource blocks (resource element, RB) in one resource grid when the subcarrier spacing is configured as μ.

Indicates the number of subcarriers in one RB. optional,

consecutive subcarriers.

It should be understood that there is a set of resource cells for each direction of transmission (uplink or downlink). For a given antenna port p, subcarrier spacing configuration μ, and transmission direction (downlink or uplink), there exists one resource grid.

The starting resource block of the resource grid is a common resource block (CRB).

4. Resource element (resource element, RE): Each element in the resource grid used for antenna port p and subcarrier spacing configuration μ is called a resource element, and is uniquely identified by (k,l) _p,μ , where k is The index of the RE in the frequency domain, l is the position of the symbol of the RE in the time domain relative to a certain reference point. Resource element (k,l) _p,μ corresponds to a physical resource and complex value

When there is no risk of confusion, or when no specific antenna port or subcarrier spacing is specified, the indices p and μ may be discarded, resulting in

Or a _k,l .

5. point A: point A is the public reference point of the resource grid.

6. Common resource blocks (common resource blocks): For the subcarrier spacing configuration μ, the common resource blocks are numbered upwards from 0 in the frequency domain. The center frequency point of subcarrier 0 of common resource block 0 of subcarrier spacing configuration μ coincides with point A, see Figure 3.

Common resource block numbering in the frequency domain

The resource elements (k, l) of the subcarrier spacing configuration μ satisfy the following formula (1)

Among them, k is defined relative to point A, so that REs with k=0 correspond to subcarriers centered on point A.

7. Physical resource blocks (physical resource blocks): The physical resource blocks of the subcarrier spacing configuration μ are defined in a partial bandwidth (bandwidth part, BWP), numbered from 0 to

where i is the number of the BWP. Physical resource blocks in BWP i

with common resource block

between satisfy the following formula (2)

in

is the common resource block where the BWP starts relative to common resource block 0. Index μ may be removed when there is no risk of confusion.

8. BWP: For a given parameter set μ _i in a BWP i on a given (given) carrier (carrier), the BWP is a subset of continuous CRBs. The starting position of the BWP

and the number of PRBs of physical resource blocks

should be satisfied respectively

and

in

Indicates the size of the resource grid,

Indicates the starting position of the resource grid. The frequency domain location relationship between the BWP and the carrier can be shown in FIG. 4 .

In general, an end-device can have up to four BWPs configured in the downlink, one of which is active at a given time; an end-device can be configured with up to four BWPs in the uplink, of which one The upstream BWP is active at a given time. If a terminal device is configured with a supplementary uplink, the terminal device may additionally configure up to four bandwidth parts in the supplementary uplink, where a single supplementary uplink BWP is active at a given time.

9. Control resource set (control-resource set, CORESET): time-frequency resource for sending a physical downlink control channel (physical downlink control channel, PDCCH). Generally, the frequency domain configuration granularity of the control resource set is 6RB. A cell can be configured with multiple CORESETs, and CORESETs do not necessarily occupy the entire system bandwidth in the frequency domain. Based on this, NR can support terminal devices with different bandwidth capabilities. As shown in Figure 5, CORESET 0 and CORESET 1 occupy part of the bandwidth in BWP 0 and BWP 1 respectively.

BWP frequency domain resource configuration: In NR systems, BWP configuration information can be configured by network devices through high-level signaling, such as high-level signaling can include radio resource control (radio resource control, RRC) signaling, etc. The specific name of the order is not limited. The configuration information may include, for example, a resource indication value (resource indication value, RIV). Based on the RIV, the terminal device can determine the starting position of the BWP (for example, the starting RB number RB _start ) and the bandwidth (for example, the number of consecutive RBs L _RBs ).

CORESET frequency domain resource configuration: network devices can indicate CORESET frequency domain resources through a bitmap. For example, each bit of the bitmap corresponds to a non-overlapping resource group containing 6 consecutive RBs, and is numbered in the order of increasing RB index in a downlink BWP. The bandwidth of the downlink BWP is

The starting CRB is

The first CRB index of the first resource group containing 6RB is

If the value of the bit in the bitmap is 1, the corresponding RB group is used for the CORESET; if the value of the bit in the bitmap is 0, the corresponding PRB group is not used for the CORESET. Optionally, if some RBs in the resource group of an RB are not included in the BWP where the CORESET is located (for example, the last resource group), then the corresponding bit of the resource group will be set to 0, that is, it will not be used for this CORESET.

10. Downlink resource configuration: NR physical downlink shared channel (physical downlink shared channel, PDSCH), for example, can perform resource configuration based on the following two resource allocation methods:

a. Downlink resource allocation Type 0 (hereinafter referred to as Type 0):

The frequency domain resource granularity configured by the downlink resource allocation Type 0 is related to the size of the resource block group (RBG).

It should be noted that the RBG is a group of continuous virtual resource blocks (virtual resource block, VRB). The size (size) of each RBG, or the number of VRBs included in each RBG, can be determined by the size of the downlink BWP. For example, the corresponding relationship between the size of the downlink BWP and the RBG is shown in Table 2 below. In Table 2, each BWP size corresponds to two different configurations (such as configuration 1 and configuration 2). Whether configuration 1 or configuration 2 is used depends on the network The device is instructed.

Table 2

BWP Size BWP Size		Configuration 1Configuration 1	Configuration 2 Configuration 2
1–361–36	22	44
37–7237–72	44	88
73–14473–144	88	1616
145–275145–275	1616	1616

For Type 0, the network device may use downlink control information (downlink control information, DCI) to instruct to allocate part or all of the RBGs in the BWP to the terminal device. For example, the DCI includes a bitmap (bitmap) with a size of N _RBGs , and each bit in the bitmap corresponds to one RBG. The highest bit (most significant bit, MSB) of the bitmap corresponds to RBG 0, the lowest bit (least significant bit, LSB) corresponds to RBG N _RBG -1, and so on.

For example, when the bit is 1, the RBG corresponding to the bit is allocated to the terminal device, and when the bit is 0, the RBG corresponding to the bit is not allocated to the terminal device.

Optionally, the RBG index starts from the lowest frequency of the BWP and is numbered in ascending order of frequency. For example, the RBG indexes are numbered in ascending order of frequency starting from the lowest frequency of the BWP, which are RBG 0, RBG1...RBG N _RBG -1.

The corresponding relationship between each RBG and VRB can be shown in Table 3 below:

table 3

Assuming that for Type 0, the bitmap in the DCI sent by the network device to the terminal device is 1010111000001, then the terminal device is allocated RBG 0, RBG 2, RBG 4, RBG 5, RBG 6 and RBG12 as shown in Table 3.

It can be seen that Type 0 supports discontinuous VRB allocation in the frequency domain, and the minimum granularity of Type 0 scheduling is one RBG. The size of the RBG can be, for example, 2RB, 4RB, 8RB or 16RB in Table 2.

b. Downlink resource allocation Type 1 (hereinafter referred to as Type 1):

For Type 1, the frequency domain resource allocated by the network device to the terminal device is a segment of continuous VRB in the downlink active BWP, where the size of the BWP is

PRB, the VRB can be interleaved or non-interleaved. For Type 1, the DCI sent by the network device to the terminal device includes a RIV, which is used to indicate downlink frequency domain resources, and the terminal device can determine the starting VRB (RB _start ) and the number of consecutive RBs (L _RBs ) through the RIV. Based on this, Type 1 supports continuous VRB allocation in the frequency domain. Unlike Type 0, whose minimum scheduling granularity is one RBG, the lowest scheduling unit of Type 1 can be one RB.

It should be noted that a VRB is a logical virtual RB and needs to be mapped to a PRB eventually. There are two types of mapping from VRB to PRB: interleaving and non-interleaving. For the non-interleaving mode, VRBs and PRBs are the same; for the interleaving mode, VRBs are mapped to PRBs according to certain rules, and at this time, consecutive VRBs are not necessarily mapped to consecutive PRBs.

In this application,

Indicates rounding down,

It means round up, and mod means modulo operation.

11. Resource allocation of downlink reference signals:

The frequency domain configuration granularity of a downlink reference signal (such as a channel state information reference signal (CSI-RS)) may be an integer multiple of 4 PRBs (such as 0, 4, ...).

The NR system supports multiple downlink reference signal (such as CSI-RS) resources (resources), and the bandwidth and starting PRB of frequency domain resources corresponding to each resource can be configured by network equipment. As mentioned above, the bandwidth of the configured frequency domain resource is an integer multiple of 4, for example, it may be 24 PRBs. The terminal device may determine the smaller bandwidth of the configured downlink reference signal (such as CSI-RS) resource bandwidth and the BWP bandwidth as the actual bandwidth of the downlink reference signal (such as CSI-RS).

12. Synchronization signal and broadcast channel block (synchronization signal and PBCH block, SSB)

The terminal device can realize time-frequency synchronization with the access network device by receiving the SSB from the access network device. In addition, the terminal device can also perform system message demodulation and the like according to the SSB. Here, related technical features involved in SSB will be described in conjunction with FIG. 6a and FIG. 6b.

(1) Composition of SSB

In the embodiment of the present application, a primary synchronization signal (primary synchronization signal, PSS), a secondary synchronization signal (secondary synchronization signal, SSS) and a PBCH together constitute an SSB. As shown in Figure 6a, in the time domain, 1 SSB occupies 4 symbols (symbols), which are symbols 0 to 3, and in the frequency domain, 1 SSB occupies 20 resource blocks (resource block, RB) (one The RB includes 12 subcarriers), that is, 240 subcarriers, and the subcarrier numbers are 0-239. The PSS is located on the middle 127 subcarriers of symbol 0, and the SSS is located on the middle 127 subcarriers of symbol 2. In order to protect the PSS and SSS, there are different protection subcarriers. The protection subcarriers are not used to carry signals, and the subcarriers are reserved on both sides of the SSS as protection subcarriers. The blank areas on both sides of the SSS in Figure 6a are protection subcarriers. carrier. PBCH occupies all the subcarriers of symbol 1 and symbol 3, and occupies all subcarriers of symbol 2 except for the subcarriers occupied by SSS. subcarriers other than the carrier).

Among them, the PSS can be used to transmit the cell ID, and the SSS can be used to transmit the cell group ID. The cell ID and the cell group ID together determine multiple physical cell identities (PCI) in the 5G communication system. Once the terminal device successfully searches the PSS and SSS, it also knows the physical cell number of the 5G carrier, and thus has the ability to parse the system information contained in the SSB.

The system information in the SSB is carried by the physical boardcast channel (PBCH). Since this information is necessary for the terminal device to access the network, it can be called the main information block (MIB). The MIB may contain the system frame number, the initial access subcarrier interval, and other information.

Due to the limited information contained in the MIB, it is not enough to support terminal equipment to access 5G cells. Therefore, the terminal device must obtain some necessary system information, such as system information block (SIB) 1. SIB1 is transmitted on the physical downlink shared channel (PDSCH). Since the terminal device has obtained the parameters used for SIB1 transmission and the distribution of control resources for scheduling it in the MIB carried by the PBCH, it can receive SIB1. In this way, the terminal device can obtain the system information necessary for accessing the 5G cell, and then can access the 5G cell after being paged.

(2) SSB sending mechanism

In the 5G communication system, for a cell (or carrier), the access network device can use a frequency point to send SSB through different beams at different times to complete the broadcast beam coverage of the cell, as shown in Figure 6b.

A set of SSBs sent by an access network device during a beam scanning process may be referred to as a synchronization signal (synchronization signal, SS) burst set (burst set). The period of SS burst set is equivalent to the period of SSB corresponding to a specific beam, which can be configured as 5ms (milliseconds), 10ms, 20ms, 40ms, 80ms or 160ms, etc. Since the terminal device cannot wait for too long on a certain frequency point when performing cell search, the default is 20 ms.

Currently, there are up to 4, 8, or 64 SSBs in an SS burst set cycle. When the carrier frequency band is less than or equal to 3GHz, there are at most 4 SSBs in one SS burst set cycle. Among them, each SS burst set is always located in the time interval of 5ms. For the illustration of SS burst set, please refer to Fig. 6b. In Fig. 6b, the period of SS burst set is 20ms, and an SS burst set includes P SSBs as an example.

The lateral transmission method provided by the embodiment of the present application will be described in detail below with reference to the accompanying drawings.

It should be understood that the following is only for ease of understanding and description, and the method provided by the embodiment of the present application is described in detail by taking the interaction between the network device and the first terminal device as an example. In some embodiments, this embodiment of the present application will also be described by taking the interaction between the second terminal device and the network device, and between the second terminal device and the first terminal device as an example.

Wherein, the first terminal device may be, for example, the above-mentioned wake-up machine, or a terminal device deployed with a wake-up machine. The first terminal device may be, for example, any one of the terminal devices 121 to 126 in FIG. 1, and the network device may be, for example, 111 in FIG. 1; 128. The network device may be, for example, the network device 112 in FIG. 1 .

The first terminal device may receive a wake-up signal (same as the first signal hereinafter) on the frequency domain resource configured by the network device. It should be understood that the wake-up signal received by the first terminal device may come from the network device, for example, the terminal devices 121 to 126 in FIG. Alternatively, the wake-up signal received by the terminal device may come from a second terminal device (such as the transmitting end device 220 in Figures 2a and 2b), for example, the

terminal device

125 or 126 in Figure 1 may receive the terminal device 124 The wakeup signal sent.

In some embodiments, the first terminal device may include a main receiver and a wake-up receiver. For example, the first terminal device may be the receiving end device 210 in FIG. 2a and FIG. 2b, and the main receiver of the first terminal device may be the The main receiver 211 in FIG. 2a and FIG. 2b, and the wake-up receiver of the first terminal device may be the wake-up receiver 212 in FIG. 2a and FIG. 2b.

However, it should be understood that this should not constitute any limitation on the execution subject of the method provided in this application. As long as the method provided by the embodiment of the present application can be executed by running the program recorded with the code of the method provided in the embodiment of the present application, it can be used as the subject of execution of the method provided in the embodiment of the present application. For example, the first terminal device shown in the following embodiments may also be replaced with components in the first terminal device, such as a chip, a chip system, or other functional modules capable of invoking programs and executing programs. A network device may also be replaced with components in the network device, such as a chip, a chip system, or other functional modules capable of invoking programs and executing programs.

It should also be understood that the wake-up signal is only an exemplary description, and the present application does not limit the name of the wake-up signal.

FIG. 7a is a schematic diagram of an interaction process of a communication method 300a provided in an embodiment of the present application.

As shown in Fig. 7a, the method 300a may include S310a and S320a. Each step in the method 300a will be described in detail below.

S310a. The network device sends first resource indication information to the first terminal device, where the first resource indication information is used to indicate at least one first frequency domain resource.

Correspondingly, the first terminal device receives first resource indication information from the network device.

S320a. The network device sends a first signal to the first terminal device, where the first signal is used to wake up the first terminal device.

Correspondingly, the first terminal device receives the first signal from the network device.

It should be noted that, the first signal may be, for example, the above-mentioned wake-up signal or wake-up frame. The first signal is carried on a first frequency domain resource. For example, the first signal may be carried on one first frequency domain resource in at least one first frequency domain resource, but it should be understood that each first frequency domain resource is may be used to bear the first signal.

Waking up the first terminal device generally means that the first terminal device turns on the main receiver to perform data communication with the network device or other terminal devices.

The awakening of the first terminal device by the first signal may also be expressed as that the first terminal device will switch from the first state to the second state after receiving the first signal. Wherein, the first state and the second state correspond to different power states, generally speaking, the power of the first terminal device in the first state is lower than the power in the second state.

For example, when the first terminal device is in the first state, the main receiver of the first terminal device is turned off, or in a dormant state, and the wake-up receiver is turned on; when the first terminal device is in the second state, the main receiver of the first terminal device The receiver is on, or called active, wake up and the receiver remains on.

Specifically, the first terminal device is in the first state when receiving the first resource indication information from the network device, and is in the second state after being awakened by the first signal when receiving the first signal. Generally speaking, when the first terminal device is in the first state, it does not receive or send signals other than the first signal.

Optionally, the first terminal device may receive the first resource indication information from the network device through the main receiver.

Optionally, the first terminal device may receive the first signal on the first frequency domain resource by waking up the receiver.

Optionally, the modulation mode of the first signal is OOK modulation, amplitude keying (ask modulation, ASK) or frequency-shift keying (frequency-shift keying, FSK) modulation.

Optionally, the number of first terminal devices may be one or more. When there are multiple first terminal devices, the network device may send its corresponding first resource indication information to the multiple first terminal devices. A terminal device receives a first signal on a first frequency domain resource indicated by its first resource indication information.

It should be noted that the at least one first frequency domain resource may be a second frequency domain resource (such as a frequency domain resource corresponding to the transmission bandwidth of the first terminal device (such as downlink BWP or downlink carrier bandwidth)), or at least one first frequency domain resource. The domain resources may be a subset of the second frequency domain resources.

The embodiment of the present application provides the following two possible implementation manners to exemplify the configuration of the first frequency domain resource.

Way 1: Divide the frequency domain resources corresponding to the transmission bandwidth of the first terminal device into multiple frequency domain units, and the first resource indication information indicates at least one first frequency domain unit in the multiple frequency domain units. One first frequency domain unit corresponds to one first frequency domain resource, that is, the frequency domain resource included in the first frequency domain unit is the first frequency domain resource.

The bandwidth of each frequency domain unit in the plurality of frequency domain units may be predefined in the network device and/or the first terminal device; or may be preconfigured, for example, when the bandwidth of each frequency domain unit is only in the network When pre-defined in the device, the network device may send signaling to the first terminal device to configure the bandwidth of each frequency domain unit; or the bandwidth of each frequency domain unit may be defined in the protocol. The bandwidth of each frequency domain unit may be the same or different, which is not limited in this application.

Exemplarily, the division of the second frequency domain resource may start from the first frequency domain position and perform division according to a preset bandwidth, so as to obtain multiple frequency domain units.

Optionally, similar to the bandwidth of each frequency domain unit, the preset bandwidth may be predefined, preconfigured, or defined in a protocol.

The first frequency domain position may be, for example, the starting position of the second frequency domain resource, or may not belong to the second frequency domain resource. When the first frequency domain position does not belong to the second frequency domain resource, the first frequency domain position may be any frequency point in the resource pool that does not belong to the second frequency domain resource. Optionally, the first frequency domain position may be a common reference point (such as point A).

Assuming that the first frequency domain location is a common reference point outside the second frequency domain resource, as shown in FIG. A plurality of frequency domain units (0 to 3) corresponding to the second frequency domain resource. Starting from this common reference point, the frequency domain is divided according to the preset bandwidth to obtain a plurality of frequency domain units corresponding to the second frequency domain resource of the first terminal device 2, as shown in FIG. 8a, the frequency domain unit 4 and the frequency domain unit 4 Some of the frequency domain resources in unit 0 do not overlap with the frequency domain resources of the first terminal device 2, then the multiple frequency domain units corresponding to the second frequency domain resources of the first terminal device 2 do not include

frequency domain units

4 and 0, or The multiple frequency domain units corresponding to the second frequency domain resources of the first terminal device 2 include

frequency domain units

4 and 0, and the

frequency domain units

4 and 0 only include frequency domain resources that overlap with the frequency domain resources of the first terminal device 2 .

Assuming that the first frequency domain position is the starting position of the second frequency domain resource, as shown in Figure 8b, starting from the starting position of the second frequency domain resource, the frequency domain is divided according to the preset bandwidth, and the first A plurality of frequency domain units (0 to 3) corresponding to the second frequency domain resource of the terminal device.

Optionally, no two of the multiple frequency domain units obtained by dividing the second frequency domain resource overlap.

When the first frequency domain position is a common reference point outside the second frequency domain resource, the network device may multiplex the first signals of different first terminal devices in the same first frequency domain unit, and send the first signals to each first terminal device corresponding to the first signal. For example, in FIG. 8a , the network device may send respective corresponding first signals to the first terminal device 1 and the first terminal device 2 in the frequency domain unit 1 . The utilization rate of frequency domain resources is improved.

All or part of the frequency domain units in the multiple frequency domain units may be at least one first frequency domain unit. When all the frequency domain units in the multiple frequency domain units are at least one first frequency domain unit, that is, when each frequency domain unit in the multiple frequency domain units is the first frequency domain unit, in some embodiments, The first resource indication information sent by the network device to the first terminal device may indicate the multiple frequency domain units. For example, the first resource indication information may indicate an identifier (such as an index) of each frequency domain unit in multiple frequency domain units. As shown in FIG. 8a, the first resource indication information received by the first terminal device 1 may include, for example, the 0 to 3, the first resource indication information received by the first terminal device 2 may include, for example, the identifications of frequency domain units 0 to 4; for another example, the first resource indication information may use 1 bit to indicate that the multiple frequency domain units are the first A frequency domain unit. In other embodiments, the network device may not send the first resource indication information to the first terminal device, and the first terminal device uses the divided frequency domain units as at least one first frequency domain unit according to a predefined rule, On this basis, the network device may indicate to the first terminal device that one frequency domain unit among the multiple frequency domain units is used to determine the transmission position of the first signal.

When some of the frequency domain units in the multiple frequency domain units are at least one first frequency domain unit, the first resource indication information sent by the network device to the first terminal device may indicate the first frequency domain unit among them.

As an example, the first resource indication information includes at least one piece of first indication information, where the first indication information is used to indicate an identifier (such as an index) of the first frequency domain unit. For example, as shown in FIG. 8a, assuming that the first resource indication information includes two first indication information, and the identifiers of the first frequency domain units respectively indicated by the two first indication information are 1 and 3, then the multiple frequency domain units

Frequency domain units

1 and 3 are at least one first frequency domain unit.

As another example, the first resource indication information includes a first bitmap, and bits in the first bitmap are in one-to-one correspondence with multiple frequency domain units corresponding to the second resource. The bits in the first bitmap are used to indicate whether the corresponding frequency domain unit is the first frequency domain unit. For example, when a bit of the first bitmap is the second value, it indicates that the corresponding frequency domain unit is the first frequency domain unit, and when a bit of the first bitmap is the third value, it indicates that the corresponding frequency domain unit is not the first frequency domain unit. Wherein, the second value may be 0, for example, and the third value may be 1; or the second value may be 1, for example, and the third value may be 0, for example. Assume that the second value is 1 and the third value is 0, see Table 4 below.

Table 4

As shown in FIG. 8b, according to the bitmap shown in Table 4, the

frequency domain units

0, 1 and 2 in the second resource are all the first frequency domain units.

In the first manner above, the transmission bandwidth of the first terminal device may be a downlink BWP or a downlink carrier bandwidth. The downlink BWP may include one of the following: a BWP of the first terminal device for receiving the first signal; an initial downlink BWP; an activated downlink BWP; and a default (default) downlink BWP.

Optionally, the downlink BWP and/or the downlink carrier bandwidth may be configured in a system message or in an RRC message.

Optionally, the subcarrier spacing of the first frequency domain resource may be the same as the subcarrier spacing of the downlink BWP or the downlink carrier bandwidth.

Optionally, the cyclic prefix type of the first frequency domain resource may be the same as the cyclic prefix type of the downlink BWP or the downlink carrier bandwidth.

The network device may send transmission bandwidth indication information to the first terminal device, where the transmission bandwidth indication information is used to indicate an identifier of a transmission bandwidth corresponding to at least one first frequency domain resource. The at least one first frequency domain resource may correspond to the same transmission bandwidth identifier, and the at least one first frequency domain resource may also correspond to a different transmission bandwidth identifier, for example, the transmission bandwidth indication information may be a BWP identifier, and/or, Carrier ID.

It can be understood that the transmission bandwidth indication information may be carried by the first resource indication information, or the transmission bandwidth indication information may be independent indication information.

Manner 2: The first resource indication information indicates the first frequency domain resource in the transmission bandwidth of the first terminal device.

Exemplarily, in manner 2, the first resource indication information includes at least one second indication information, and the second indication information includes a RIV, where the RIV is used to indicate a starting position and bandwidth of a first frequency domain resource.

Before this, the network device needs to generate the RIV according to the starting position RB _start and the bandwidth L _RBS of the first frequency domain resource to be indicated. For example, the network device may have the bandwidth L _RBS of the first frequency domain resource and the transmission bandwidth of the first terminal device as

When the following formula (3) is satisfied, the RIV is obtained according to the following formula (4), and the bandwidth L _RBS of the first frequency domain resource and the transmission bandwidth of the first terminal device are

When the following formula (3) is not satisfied, RIV is obtained according to the following formula (5).

where L _RBS is greater than or equal to 1 and less than

The terminal device may determine the starting position and bandwidth of the first frequency domain resource according to the RIV in the received second indication information. For example, the terminal device can be at the RIV and the transmission bandwidth of the first terminal device is

When the following formula (6) is satisfied, the starting position RB _start and the bandwidth L _RBS of the first frequency domain resource are determined according to the following formula (7a) and formula (7b), and the transmission bandwidth between the RIV and the first terminal device is

When the following formula (6) is not satisfied, the starting position RB _start and the bandwidth L _RBS of the first frequency domain resource are determined according to the following formula (8a) and formula (8b).

The transmission bandwidth of the first terminal device involved in the above-mentioned method 2 has been described in the above-mentioned method 1, and will not be repeated here.

In the second manner above, the network device implements efficient configuration of at least one first frequency domain resource through the RIV coding manner, saving signaling overhead.

FIG. 7b is a schematic diagram of an interaction process of a communication method 300b provided in an embodiment of the present application. As shown in Figure 7a, the method 300b includes:

S310b. The network device sends first resource indication information to the first terminal device and the second terminal device respectively.

Correspondingly, the first terminal device and the second terminal device respectively receive the first resource indication information from the network device.

S320b. The second terminal device sends the first signal to the first terminal device on the first frequency domain resource.

Correspondingly, the first terminal device receives the first signal from the second terminal device on the first frequency domain resource.

The difference between the embodiment shown in FIG. 7b and the embodiment shown in FIG. 7a is that in the above S320b, the second terminal device sends the first signal to the first terminal device instead of the network device sending the first signal to the first terminal device . In this case, in the above S310b, the network device may also send the first resource indication information to the second terminal device.

In the above S310b, the process of the network device sending the first resource indication information to the first terminal device is similar to the above S310a in FIG. 7a , and will not be repeated here. The first resource indication information sent by the network device to the second terminal device is similar to the first resource indication information sent by the network device to the first terminal device, and will not be repeated here.

In the above S320b, both the second terminal device and the first terminal device determine the first frequency domain resource used for transmitting the first signal based on the first resource indication information sent by the network device, so as to implement the second terminal device and the first terminal device The device transmits the first signal on the first frequency domain resource.

In the embodiment shown in Fig. 7a and Fig. 7b, the network device configures multiple first frequency domain resources to the first terminal device (or to the first terminal device and the second terminal device). When the terminal device sends the first signal, it may send the first signal to the corresponding first terminal device on each first frequency domain resource, thereby reducing paging false alarms (UE perspective) or improving paging capacity (gNB perspective).

Optionally, the network device may use a system message to carry the first resource indication information, so as to configure at least one first frequency domain resource.

In some embodiments, the first signal may be transmitted on the above-mentioned first frequency domain resource. However, when the network device needs to send its respective first signal to multiple first terminal devices, in order to ensure improved data transmission efficiency, Multiple first signals may be frequency-division multiplexed. In other words, the network device may send each first signal through different first frequency resources. As mentioned above, the first signal is used as a wake-up signal or a wake-up frame, and the first terminal device often uses non-coherent detection (such as envelope detection) to monitor the first signal. In order to avoid interference between signals, a certain guard band (or called a guard band) needs to be reserved between the first signals. Referring to Fig. 8c, the bandwidth of the first signal of each terminal device (such as the first terminal devices 1 to 4) may be smaller than the bandwidth of the first frequency domain resource carrying the first signal.

Optionally, the center frequency point of the first signal is the same as the center frequency point of the first frequency domain resource carrying the first signal.

Optionally, the relative position of the first signal in the first frequency domain resource may be configured by a network device, and the first frequency domain resource is used to bear the first signal.

In some embodiments, in order to reduce the impact of the first frequency domain resource used to carry the first signal on the existing resource allocation of NR, the resource location of the first frequency domain resource in this embodiment (for example, the starting point of the first frequency domain resource start position and/or end position) and/or the bandwidth of the first frequency domain resource needs to meet the restriction of an integer multiple of the first value. Wherein, the first value is determined based on n first parameters, and n is a positive integer.

Exemplarily, when n is equal to 1, the first value may be the value of the first parameter; when n is greater than 1, the first value may be the least common multiple or the greatest common divisor of the values of n first parameters. In another example, when n is 2, the first value may be the larger or smaller value of the n first parameters. In another example, when n is greater than 2, the first value may be the n first The maximum or minimum value of the parameter's numeric value.

The n first parameters may include at least one of the following, for example:

The frequency domain configuration granularity of the downlink reference signal (such as CSI-RS) of the second frequency domain resource, for example, the frequency domain configuration granularity of the CSI-RS is 4RB;

The frequency domain configuration granularity of the control resource set of the second frequency domain resource, as mentioned above, the frequency domain configuration granularity of the control resource set may be, for example, 6RB;

The size of the resource block group RBG of the second frequency domain resource, for example, the size of the RBG configured for the PDSCH downlink data resource mentioned above may be, for example, 2, 4, 6, 8, 16 RB;

The bandwidth supported by the wake-up receiver of the first terminal device, for example, the bandwidth may be a value of the bandwidth, such as 100kHz, 3MHz or 6RB, etc.;

The bandwidth supported by the radio frequency filter of the wake-up receiver of the first terminal device, which may also be the value of the above-mentioned bandwidth;

The center frequency point of the RF filter of the wake-up receiver of the first terminal device.

Wherein, the bandwidth supported by the wake-up receiver of the first terminal device, the bandwidth supported by the radio frequency filter of the wake-up receiver, and the center frequency point of the radio frequency filter of the wake-up receiver may be the capability information reported by the network device from the first terminal device obtained from .

The resource position of the first frequency domain resource (for example, the start position and/or the end position of the first frequency domain resource) and/or the bandwidth of the first frequency domain resource must meet the above restrictions, which can reduce the The impact of the first frequency domain resources of the signal on the allocation of existing NR resources (such as control resource sets, downlink reference signal resources, and downlink data resources) has less resource fragmentation. An exemplary description will be made below in conjunction with FIG. 8d.

Referring to Fig. 8d, assuming that the bandwidth of the first frequency domain resource is 6 RB, the first frequency domain resource may overlap with a certain frequency domain resource in the control resource set. On this basis, the first frequency domain resource and the control resource set should have a frequency domain resources overlap, but should avoid making the first frequency domain resource cross multiple frequency domain resources in the control resource set.

Optionally, the resource position of the first frequency domain resource (for example, the start position and/or end position of the first frequency domain resource) and/or the bandwidth of the first frequency domain resource, and the above-mentioned constraints that need to be satisfied may be a protocol defined or implemented by network devices.

On the basis of the above-mentioned FIG. 7a or FIG. 7b, some or all of the steps in FIG. 9 may be included.

In order to avoid the influence of the first signal on the NR public signal, the frequency domain resource of the first signal should be far away from the frequency domain resource where the SSB and/or CORESET 0 of the NR are located during configuration.

For example, in a configuration manner, the transmission bandwidth associated with the first signal does not include the SSB, and/or, the transmission bandwidth associated with the first signal does not include CORESET 0. It should be noted that excluding means that there is no overlap in the frequency domain, and the transmission bandwidth associated with the first signal is determined according to the above transmission bandwidth indication information.

For example, in another configuration mode, the transmission bandwidth associated with the first signal includes the SSB, the first signal is configured on the side far away from the SSB in the frequency domain within the transmission bandwidth, and the lowest frequency position of the transmission bandwidth and the SSB between The distance f1, the distance f2 between the highest frequency position of the transmission bandwidth and the SSB, the first signal should be configured on the larger side of f1 and f2 within the transmission bandwidth. And/or, the transmission bandwidth associated with the first signal includes CORESET 0, the first signal is configured on a side far away from CORESET 0 in the frequency domain within the transmission bandwidth, and the distance between the lowest frequency position of the transmission bandwidth and CORESET 0 f1, f2 of the distance between the highest frequency position of the transmission bandwidth and CORESET 0, the first signal should be configured on the larger side of f1 and f2 within the transmission bandwidth. The transmission bandwidth associated with the first signal is determined according to the above transmission bandwidth indication information.

FIG. 9 is a schematic interaction flowchart of a communication method 400 provided by an embodiment of the present application. All or part of the steps in S410, S440 to S460 shown in Figure 9 can be implemented on the basis of the embodiment shown in Figure 7a or Figure 7b, for ease of understanding, Figure 9 is only combined with Figure 7a for example instruction of.

S420 and S430 in FIG. 9 are similar to S310a and S320a in FIG. 7a respectively, and will not be repeated here.

In the foregoing

manners

1 and 2, the quantity of the first frequency domain resources indicated by the first resource indication information may be one or more. If the first resource indication information indicates a first frequency domain resource, the first terminal device may receive the first signal sent by the network device on the first frequency domain resource. If the first resource indication information indicates multiple (including two) first frequency domain resources, the first terminal device may determine a third frequency domain resource used to carry the first signal from at least one first frequency domain resource, That is, S440 in FIG. 9 .

The first terminal device determines the third frequency domain resource for carrying the first signal from at least one first frequency domain resource, which may include the following two possible examples:

Example 1: The network device configures the third frequency domain resource to the first terminal device.

For example, the network device sends third resource indication information to the first terminal device, where the third resource indication information includes an identifier (such as an index) of the third frequency domain resource, and correspondingly, the first terminal device receives the third resource information sent by the network device Instructions. Wherein, each first frequency domain resource corresponds to an index (value).

Optionally, if the second terminal device is the wake-up transmitter device of the first terminal device, the network device may further configure the third frequency domain resource to the second terminal device.

Example 2: The first terminal device determines the third frequency domain resource according to a predefined rule. Specifically, the following four possible implementation manners may be included.

Implementation manner 1: The first terminal device determines the third frequency domain resource according to its identifier and the quantity of the first frequency domain resource configured by the network device.

For example, the first terminal device may determine the third frequency domain resource according to the following formula (9), that is, determine the first frequency domain resource identified as _Q1 among the at least one first frequency domain resource.

Q ₁ = UE_ID mod N _WUR (9)

Assuming that there is a communication connection between the network device and n first terminal devices, the identifiers UE_ID of the n first terminal devices are 1, 2...n in sequence, and the number of first frequency domain resources N _WUR =5, then, when UE_ID is 1 , the third frequency domain resource is the first frequency domain resource with the identifier Q ₁ =1, when the UE_ID is 2, the third frequency domain resource is the first frequency domain resource with the identifier Q ₁ =2, and so on.

Implementation Mode 2: The first terminal device determines the third frequency domain resource according to its service type and a first correspondence relationship, where the first correspondence relationship is a correspondence relationship between the service type and the first frequency domain resource identifier.

Exemplarily, the service type may include reduced capability (reduced capability, REDCAP), enhanced mobile bandwidth (enhanced mobile broadband, eMBB), Internet of Things or non-Internet of Things, and the like.

For example, in the first correspondence, REDCAP corresponds to the first frequency domain resource 1, and eMBB corresponds to the first frequency domain resource 2; or the Internet of Things corresponds to the first frequency domain resource 1, and non-IoT terminals correspond to the first frequency domain resource 2, etc. Assuming that the service type of the first terminal device is REDCAP, the third frequency domain resource is the first frequency domain resource 1 in the at least one first frequency domain resource.

Implementation manner three: the first terminal device determines the third frequency domain resource according to its paging probability and the second corresponding relationship, and the second corresponding relationship is the corresponding relationship between the paging probability and the first frequency domain resource identifier.

For example, in the second correspondence, a paging probability value may correspond to a first frequency domain resource identifier, or a paging probability interval may correspond to a first frequency domain resource identifier. Generally, the paging probability intervals do not overlap. For example, the paging probability interval 1 corresponds to the first frequency domain resource 1, the paging probability interval 2 corresponds to the first frequency domain resource 2, and so on.

Assuming that the paging probability of the first terminal device belongs to the paging probability interval 2, then the third frequency domain resource of the first terminal device is the first frequency domain resource 2 in the at least one first frequency domain resource.

Implementation manner four: the first terminal device determines the third frequency domain resource according to its identifier and the weight corresponding to each first frequency domain resource in the at least one first frequency domain resource.

For example, the weights corresponding to the m first frequency domain resources are W(0), W(1), W(2)...W(m) in sequence. The first terminal device may determine a minimum value i that makes the following formula (10) valid according to the following formula (10), where the minimum value i is an identifier of a first frequency domain resource in at least one first frequency domain resource, and the first The frequency domain resource is the third frequency domain resource.

Minimum value i of UE_ID mod W<W(0)+W(1)+…+W(i) (10)

Wherein, W is the sum of the weights from W(0) to W(i).

For example, assuming m=4, W(0)=1, W(1)=2, W(2)=3, W(3)=4, W(4)=5, then W=15, assuming UE_ID is 0 , then when i=0, UE_ID mod W=0, W(0)=1, the above formula (10) holds true, then the third frequency domain resource of the first terminal device 0 is the first frequency domain resource in at least one first frequency domain resource A frequency domain resource 0; assuming UE_ID is 1, then when i=0, UE_ID mod W=1, W(0)=1, the above formula (10) is not valid, when i=1, UE_ID mod W=1, W( 0)+W(1)=3, the above formula (10) holds true, then the point frequency domain resource of the first terminal device 1 is the first frequency domain resource 1 in at least one first frequency domain resource.

It can be understood that, in the above example 2, if the second terminal device is the wake-up transmitter device of the first terminal device, the second terminal device may determine the third frequency domain resources.

It should be noted that the UE_ID in the above implementation method can be 5G-S-TMSI mod 1024, and 5G-S-TMSI is the abbreviation of 5G S-Temporary Mobile Subscription Identifier. If the first terminal device or the second terminal device does not have 5G-S-TMSI, for example, the first terminal device or the second terminal device has not registered to the network, the first terminal device or the second terminal device shall use the default UE_ID=0. In the above implementation, UE_ID can also be other identifiers assigned by network equipment, which are used to distinguish terminal equipment when receiving the first signal. The value range can be less than or equal to 1024. Here, the network equipment can be an access network equipment or a core network equipment.

It should be noted that, in the above implementation, mod is a mathematical operation symbol, representing a remainder operation, for example, a mod b=c, indicating that the remainder after dividing a by b is c.

The first terminal device may send the first signal on the third frequency domain resource determined in S440 above. As shown above, the first signal may be sent by the network device or by the second terminal device.

In some embodiments, the first signal may be transmitted on the third frequency domain resource determined in S440 above. In order to avoid interference between signals, a certain guard band (or called a guard band) needs to be reserved between the first signals. Based on this, the bandwidth of the first signal may be smaller than the bandwidth of the third frequency domain resource carrying the first signal.

Optionally, the center frequency point of the first signal is the same as the center frequency point of the third frequency domain resource carrying the first signal.

The resource position of the first signal in the third frequency domain resource (for example, the bandwidth of the first signal and/or the position of the center frequency point) may be predefined or configured by the network device.

Referring to S450 in FIG. 9, the network device may send second resource indication information to the first terminal device, where the second resource indication information is used to indicate the resource position of the first signal in the first frequency domain resource (for example, the first signal bandwidth and/or center frequency location). It can be understood that, after the first terminal device determines the third frequency domain resource, the second resource indication information is used to indicate the resource position of the first signal in the third frequency domain resource.

Optionally, the second resource indication information and the first resource indication information may be sent together by the network device, or the second resource indication information may be sent as independent resource indication information.

Optionally, this embodiment of the present application does not limit the order in which the network device sends the first resource indication information and the second resource indication information.

Referring to FIG. 9 , in S410, the first terminal device sends capability information to the network device, and correspondingly, the network device receives the capability information sent by the first terminal device.

Optionally, the capability information may be used to indicate at least one of the following:

Whether the first terminal device supports waking up the receiver;

Frequency band information supported by the wake-up receiver of the first terminal device, for example, the frequency band information may be, for example, a frequency band identifier;

Optionally, S410 may be performed before S420 in the embodiment shown in FIG. 9 , for example.

The network device may determine whether to configure at least one first frequency domain resource for the first terminal device according to the capability information reported by the first terminal device. A terminal device sends at least one of first resource indication information, second resource indication information, and third resource indication information.

The network device may determine the configured frequency band, bandwidth, and/or central frequency point, etc. of the first frequency domain resource according to the capability information reported by the first terminal device.

Optionally, the first terminal device may send the foregoing capability information through the main receiver.

Optionally, the first terminal device may report the above capability information through the four-step random access process or an uplink message in the four-step random access process; or the first terminal device may report the above-mentioned capability information through the terminal device capability information or the terminal device auxiliary message. capability information.

On the basis of the embodiment shown in FIG. 9 , in order to reduce the impact of the first frequency domain resource used to carry the first signal on the existing resource allocation of NR, the resource location of the first frequency domain resource in this embodiment (for example, the first The start position and/or end position of the frequency domain resource) and/or the bandwidth of the first frequency domain resource need to meet the restriction of an integer multiple of the first value. The first numerical value has been described in the foregoing examples, and will not be repeated here.

Therefore, in this embodiment of the present application, the first terminal device may determine the first frequency domain resource used to bear the first signal by receiving the first resource indication information sent by the network device, and receive the resource used for carrying the first signal on the first frequency domain resource. The first signal to wake itself up.
