With the popularity of 5G NR system MTC and internet of things (internet of things, ioT) communications, more and more IoT devices have been deployed in people's lives. For example: intelligent water meters, shared bicycles, smart cities, environmental monitoring, smart homes, forest fire protection and other devices targeting sensing and data acquisition, and the like. In the future, ioT devices will be ubiquitous, potentially embedded in each garment, each package, each key, and almost all offline items will be online with the internet of things technology enabled. At the same time, however, the process of implementing the internet of things also presents a small challenge to the industry due to the wide and numerous distribution ranges of IoT devices, which is the power supply problem at first. Currently, ioT is still largely driven by operators, and IoT modules need to communicate with base stations using standard cellular protocols. Because the base station needs to cover as large an area as possible, the IoT module needs to be able to still communicate when far from the base station, which still requires up to 30mA of current consumption when the IoT device is in wireless communication, so the current IoT module still needs to use a battery with higher capacity to work, which also makes the IoT module difficult to be small in size and increases the cost of the IoT device.

In addition, some low-power terminals play an important role in medical treatment, smart home, industrial sensors, wearable devices and other internet of things applications. However, since such terminals are limited in size, it is difficult to simply increase the battery capacity if the operation time of these devices is to be prolonged. Therefore, to achieve the prolongation of the terminal duration, the power consumption of wireless communication needs to be reduced, wherein the radio transceiver is one of the most power-consuming components.

Therefore, in order to further popularize IoT, the IoT module is implanted into a human body or a smaller object, it is impossible to match with a higher-capacity battery, and the smaller battery must be used even completely to get rid of the limitation of the battery, or a method for reducing the power consumption of the radio transceiver is designed to overcome the limitation problems of the cost, the size, the power consumption and the like of the IoT device.

Currently, when the terminal device is operated in a power saving mode according to the wireless lan standard IEEE802.11 defined by the institute of electrical and electronics engineers (institute of electrical and electronics engineers, IEEE), the terminal device needs to wake up periodically after entering a sleep state, receive control information from the AP, and according to an indication carried in the control information (such as a traffic indication map (traffic indication ma, TIM)), the terminal device can sense whether there is downlink data from the AP. If the terminal device is in a sleep state for a long time, lower power consumption can be enjoyed, but the delay of receiving data can be increased. In order to enable battery-operated terminal devices to achieve a balance between power efficiency and data reception delay, the IEEE802.11 TGba organization holds true, developing a draft of IEEE802.11ba (also known as wake-up radio).

The goal of IEEE 802.11ba WUR is to enable active devices with power consumption less than 1 mW. For this purpose, the terminal device is equipped with two Radio chains, namely a main connection Radio (primary connection Radio, PCR) (which may also be referred to as main receiver) and a Companion connection Radio (company Radio) (which may also be referred to as wake-up receiver (WUR)). Among them, PCR consumes much power, and it is desirable to switch to sleep mode as long as possible, thereby significantly reducing power consumption; the WUR has smaller power consumption, and is configured to monitor a wake-up frame sent by the AP, and wake-up the PCR after the wake-up frame is monitored.

As shown in connection with fig. 2a, a primary receiver 211 and a wake-up receiver 212 are deployed in a receiving end device 210. When the transmitting end device 220 (e.g., an AP or a terminal device) is not transmitting data, the primary receiver is turned off, also referred to as being in a sleep state, and the wake-up receiver is turned on; as shown in fig. 2b, when the transmitting end device 220 transmits data, wake-up data (e.g., the above wake-up frame) is first transmitted, 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, which is also called in an active state, and at this time, the receiving end device 210 receives, through the main receiver 211, the data transmitted by the transmitting end device 220 after the wake-up data.

It should be noted that, the information bits of the wake-up machine are modulated into on-off key (OOK) symbols, and the transmitting end device uses these OOK symbols to mask the generated narrowband orthogonal frequency division multiplexing (orthogonal frequency division multiplexing, OFDM) waveform (i.e., OOK waveform), so as to further optimize the OOK waveform, where the OOK symbols are carried on 13 subcarriers, which is called multi-carrier (MC) OOK in the wireless lan standard IEEE 802.11ba defined by the institute of electrical and electronics engineers (institute of electrical and electronics engineers, IEEE). On the receiving end device side, OOK demodulation does not require any channel equalization in the frequency and time domains, so the receiving end device listens by waking up the receiver for non-coherent detection (e.g., envelope detection). With incoherent detection, the receiving end device does not need to keep/track of the oscillation rate with high accuracy. Therefore, a phase-locked loop can be avoided, and the power consumption of the receiving side can be further reduced.

It should be understood that OOK symbols are only one example of WUR wakeup frames and do not constitute any limitation to the present application.

Based on this, in the 3GPP at the institute of R18 potential research direction discussion, month 2021, internet of things enhancement technology was discussed and it was disclosed that 5G evolution (5G-Advanced) would start from R18 and introduce WUR in the 5G NR system. However, when WUR techniques are applied in NR systems, there is currently no effective solution for how the wake-up receiver determines the frequency domain resources on which to receive the wake-up signal (e.g. the wake-up frame described above), in other words, on which frequency domain resources the wake-up receiver listens for the wake-up signal.

In view of the foregoing, embodiments of the present application provide a solution for determining frequency domain resources, so that a wake-up signal transmitting end (e.g., a network device or a terminal device) and a wake-up receiver may transmit a wake-up signal on the determined frequency domain resources.

To facilitate an understanding of the embodiments of the present application, the terms referred to in this application are first briefly described.

1. Parameter set (numerology): in an NR system, a parameter set is introduced for adapting to OFDM waveforms with different subcarrier intervals, so that the subcarrier intervals are not limited and can be adapted according to different use scenes.

The set of transmission parameters supported by the NR system is shown in table 1 below:

TABLE 1

μ	Δf＝2 ^μ ·15[kHz]	Cyclic prefix (cyclic prefix)
			0	15	Conventional (normal)
1	30	normal
			2	60	normal, extended (extended)
3	120	normal
			4	240	normal

Where Δf is the subcarrier spacing, 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 channel environment experienced by different signals transmitted on the same antenna port is the same.

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

Sub-carriers and->

A plurality of OFDM symbols, wherein->

Represents the number of Resource Blocks (RBs) within one resource grid when the subcarrier spacing is configured as μ. />

The number of subcarriers in one RB is represented. Optionally, a->

Successive subcarriers.

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

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

4. Resource Element (RE): each element in the resource grid for antenna port p and subcarrier spacing configuration μ is called a resource element and is defined by (k, l) _p,μ A unique identity, where k is the index of the RE in the frequency domain and l is the position of the symbol of the RE in the time domain relative to some reference point. Resource element (k, l) _p,μ Corresponding to a physical resource and complex value

When there is no risk of confusion, or no specific antenna port or subcarrier spacing is specified, the indices p and μmay be discarded, resulting in +.>

Or a _k,l 。

5. Point A: point A is a common reference point for the resource grid.

6. Common resource block (common resource blocks): for a subcarrier spacing configuration μ, the common resource blocks are numbered in the frequency domain starting from 0 up. The center frequency point of subcarrier 0 of common resource block 0 of subcarrier spacing configuration μ coincides with point a, see fig. 3.

Common resource block number (number) in the frequency domain

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

Where k is defined with respect to point a such that RE for k=0 corresponds to a subcarrier centered around point a.

7. Physical resource block (physical resource blocks): the physical resource blocks of the subcarrier spacing configuration mu are defined in a partial Bandwidth (BWP) and numbered from 0 to

Where i is the number of BWP. Physical resource block in BWP i +.>

And common resource block->

8. BWP: for a given set of parameters mu in BWP i on a given (given) carrier (carrier) _i BWP is a subset of consecutive CRBs. Start position of BWP

And->

Wherein->

Representing the size of the resource grid, +.>

Representing the starting position of the resource grid. The frequency domain positional relationship between BWP and carrier may be as shown in fig. 4.

In general, one terminal device may configure up to four BWP in the downlink, one of which is in an active state at a given time; up to four BWP may be configured in the uplink by one terminal device, with one uplink BWP being active at a given time. If a terminal device is configured with a supplemental (supplementary) uplink, the terminal device may additionally configure up to four bandwidth portions in the supplemental uplink, where a single supplemental uplink BWP is active at a given time.

9. Control-resource set (CORESET): is a time-frequency resource for transmitting a physical downlink control channel (physical downlink control channel, PDCCH). In general, the frequency domain configuration granularity of the control resource set is 6RB. A cell may configure multiple CORESETs, and CORESETs do not necessarily occupy the entire system bandwidth in the frequency domain, based on which NR can support terminal devices of different bandwidth capabilities. As shown in fig. 5, CORESET 0 and CORESET 1 occupy a portion of the bandwidth in BWP 0 and BWP 1, respectively.

BWP frequency domain resource configuration: in the NR system, the BWP configuration information may be configured by the network device through higher layer signaling, which may include radio resource control (radio resource control, RRC) signaling, etc., and specific names of the higher layer signaling are not limited in this application. 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 start position of the BWP (e.g., start RB number RB _start ) And bandwidth (e.g. number of consecutive RBs L _RBs )。

CORESET frequency domain resource configuration: the network device may indicate CORESET frequency domain resources via a bitmap (bitmap).For example, each bit of the bitmap corresponds one-to-one to a non-overlapping resource group comprising 6 consecutive RBs and is numbered in increasing order of RB index within a downlink BWP having a bandwidth of

The starting CRB is->

The first CRB index of the first resource group including 6RB is +.>

If the bit in the bitmap has a value of 1, the corresponding RB group is used for CORESET; if the bit in the bitmap has a value of 0, the corresponding PRB group is not used for CORESET. Alternatively, if some RBs within a resource group of one RB are not contained within the BWP where the CORESET is located (e.g., the last resource group), then the corresponding bit of that resource group will be set to 0, i.e., not used for that CORESET.

10. And (3) downlink resource allocation: the NR physical downlink shared channel (physical downlink shared channel, PDSCH) may be configured for example based on two resource allocation schemes listed below:

a. downlink resource allocation Type 0 (hereinafter abbreviated as Type 0):

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

The RBG is a set of consecutive virtual resource blocks (virtual resource block, VRB). The size (size) of each RBG, or the number of VRBs included in each RBG, may be determined by the size of the downstream BWP. For example, the correspondence between the size of the downlink BWP and the RBG is shown in table 2 below, where each BWP size in table 2 corresponds to two different configurations (e.g., configuration (configuration) 1 and configuration (configuration) 2), and the network device indicates whether the configuration 1 or the configuration 2 is adopted.

TABLE 2

For Type 0, the network device may indicate that some or all RBGs in the BWP are allocated to the terminal device through downlink control information (downlink control information, DCI). For example, a DCI includes a single element of size N _RBG A bitmap), each bit in the bitmap corresponding to an RBG. The highest bit (most significant bit, MSB) of the bitmap corresponds to RBG 0, and 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.

Alternatively, RThe BG index starts from the lowest frequency of BWP and is numbered in order of increasing frequency. For example, RBG indexes are numbered in order of increasing frequency starting from the lowest frequency of BWP, RBG 0, RBG1 … RBG N in order _RBG -1。

The correspondence between each RBG and VRB can be as shown in table 3 below:

TABLE 3 Table 3

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

As can be seen, type 0 supports discontinuous VRB allocation on the frequency domain, the minimum granularity of Type 0 scheduling is one RBG, and the size of the RBG may be, for example, 2RB, 4RB, 8RB or 16RB in table 2.

b. Downlink resource allocation Type1 (hereinafter abbreviated as Type 1):

for Type1, the frequency domain resource allocated to the terminal device by the network device activates a segment of continuous VRB in the BWP for downlink, where the BWP has a size of

The number of PRBs, the VRB, may be interleaved or non-interleaved. For Type1, the DCI transmitted by the network device to the terminal device includes an RIV for indicating downlink frequency domain resources, through which the terminal device can determine a start VRB (RB _start ) Number of continuous RBs (L _RBs ). Based on this, type1 supports continuous VRB allocation on the frequency domain, and unlike Type 0 minimum scheduling granularity of one RBG, the lowest scheduling unit of Type1 may be one RB.

The VRB is a logical virtual RB, and eventually needs to be mapped to a PRB. The mapping of VRBs to PRBs is divided into two ways, interleaving and non-interleaving. For the non-interleaving mode, the VRB and the PRB are the same; for the interleaving scheme, VRBs are mapped to PRBs according to a certain rule, and consecutive VRBs are not necessarily mapped to consecutive PRBs.

In the present application,

representing a rounding down, a +.>

Representing an upward rounding, mod represents a modulo operation.

11. Resource allocation of downlink reference signals:

the frequency domain configuration granularity of the downlink reference signal (e.g., channel state information reference signal (channel state information reference signal, CSI-RS)) may be an integer multiple of 4 PRBs (e.g., 0,4, … …).

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

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

The terminal device may achieve time-frequency synchronization with the access network device by receiving SSBs from the access network device. In addition, the terminal device may also perform system message demodulation and the like according to the SSB. Here, the related art features related to SSB will be described with reference to fig. 6a and 6 b.

(1) Construction of SSB

In the embodiment of the present application, the primary synchronization signal (primary synchronisation signal, PSS), the secondary synchronization signal (secondary synchronisation signal, SSS) and the PBCH together form one SSB. As shown in fig. 6a, in the time domain, 1 SSB occupies 4 symbols (symbol), which is symbol 0 to symbol 3, and in the frequency domain, 1 SSB occupies 20 Resource Blocks (RBs) (one RB includes 12 subcarriers), that is, 240 subcarriers, and the subcarrier numbers are 0 to 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 PSS and SSS, there are different guard subcarriers, respectively, which are not used to carry signals, and the guard subcarriers are reserved on both sides of SSS, respectively, as the guard subcarriers, for example, the blank areas on both sides of SSS in fig. 6a are the guard subcarriers. The PBCH occupies all the subcarriers of symbol 1 and symbol 3, and occupies a part of the remaining subcarriers (i.e., the subcarriers other than the guard subcarriers among the remaining subcarriers) among all the subcarriers of symbol 2 except the subcarriers occupied by the SSS.

Wherein the PSS may be used to transmit a cell number and the SSS may be used to transmit a cell group number, the cell number and the cell group number together determining a plurality of physical cell numbers (physical cell identity, PCI) in the 5G communication system. Once the terminal device successfully searches the PSS and SSS, it also knows the physical cell number of this 5G carrier, thus having the capability of parsing the system message contained in the SSB.

The system messages in SSB are carried by the physical broadcast channel (physical boardcast channel, PBCH), which may be referred to as a master message block (main information block, MIB) since this information is the information necessary for the terminal device to access the network. The MIB may include a system frame number, an initial access subcarrier spacing, and other information.

The information contained in MIB is limited and is not sufficient to support access of terminal equipment to 5G cells. Therefore, the terminal device must also get some necessary system messages again, such as the system information block (system information block, SIB) 1.SIB1 is transmitted on a physical downlink shared channel (physical downlink shared channel, PDSCH), and SIB1 can be received because the terminal device has acquired parameters used for SIB1 transmission and control resource distribution conditions for scheduling it in MIB carried by PBCH. In this way, the terminal device can acquire the system information necessary for accessing the 5G cell, and then can access the 5G cell after being paged.

(2) SSB transmission mechanism

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

The set of SSBs transmitted by the access network device during one beam sweep may be referred to as a synchronization signal (synchronization signal, SS) burst set (burst set). The period of SS burst set corresponds to the period of SSB corresponding to one specific beam, and may be configured to be 5ms (millisecond), 10ms, 20ms, 40ms, 80ms, 160ms, or the like. Since the terminal device cannot wait for an excessive time at a certain frequency point when performing cell search, it performs cell search by default in 20 ms.

Currently, there are at most 4, 8 or 64 SSBs within one SS burst set period. When the carrier frequency band is less than or equal to 3GHz, there are at most 4 SSBs in one SS burst set period. Wherein each SS burst set is always located within a 5ms time interval. For an illustration of SS burst set reference is made to fig. 6b, fig. 6b taking the example that the period of SS burst set is 20ms and that one SS burst set comprises P SSBs.

The lateral transmission method provided in 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 details of the method provided in the embodiments of the present application are given only for convenience of understanding and explanation, taking interaction between the network device and the first terminal device as an example. In some embodiments, embodiments of the present application will also be described with reference to an example of interaction between a second terminal device and a network device, and a second terminal device and a first terminal device.

The first terminal device may be, for example, the wake-up machine described above, or a terminal device in which the wake-up machine is deployed. The first terminal device may be any one of the terminal devices 121 to 126 in fig. 1, for example, and the network device may be 111 in fig. 1, for example; or the first terminal device may be, for example,

terminal device

127 or 128 of fig. 1, and the network device may be, for example, network device 112 of fig. 1.

The first terminal device may receive a wake-up signal (as hereinafter the first signal) on the frequency domain resources 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. 1 may receive the wake-up signal sent by the network device 111, and the

terminal device

127 or 128 may receive the wake-up signal sent by the network device 112; alternatively, the wake-up signal received by the terminal device may come from a second terminal device (e.g., the transmitting end device 220 in fig. 2a and 2 b), e.g., the

terminal device

125 or 126 in fig. 1 may receive the wake-up signal sent by the terminal device 124.

In some embodiments, the first terminal device may comprise a primary receiver and a wake-up receiver, e.g. the first terminal device may be the receiving end device 210 in fig. 2a and 2b, the primary receiver of the first terminal device may be the primary receiver 211 in fig. 2a and 2b, and the wake-up receiver of the first terminal device may be the wake-up receiver 212 in fig. 2a and 2 b.

It should be understood that this should not constitute any limitation as to the subject matter of the method provided herein. The method provided in the embodiment of the present application can be executed as a main body of execution of the method provided in the embodiment of the present application, as long as the program recorded with the code of the method provided in the embodiment of the present application can be executed. For example, the first terminal device shown in the following embodiments may be replaced by a component in the first terminal device, such as a chip, a chip system, or other functional modules capable of calling a program and executing the program. The network device may also be replaced by a component in the network device, such as a chip, a system on a chip, or other functional modules capable of calling and executing programs, etc.

It should also be understood that the wake-up signal is only an exemplary illustration and the name of the wake-up signal is not limited in this application.

Fig. 7a is an interaction flow diagram of a communication method 300a according to an embodiment of the present application.

As shown in fig. 7a, the method 300a may include S310a and S320a. The steps in method 300a are 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 the 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 wake-up signal or the wake-up frame above. The first signal is carried on first frequency domain resources, e.g. the first signal may be carried on one of the at least one first frequency domain resource, but it will be appreciated that each of the first frequency domain resources may be used to carry the first signal.

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

The wake-up of the first terminal device by the first signal may also be expressed as a transition from the first state to the second state after the first terminal device receives the first signal. The first state and the second state correspond to different power states, and generally, the power of the first terminal device in the first state is smaller than the power of the first terminal device in the second state.

For example, when the first terminal device is in the first state, the primary receiver of the first terminal device is turned off, otherwise referred to as being in a sleep state, and the wake-up receiver is turned on; when the first terminal device is in the second state, the primary receiver of the first terminal device is turned on, otherwise known as being in an active state, and the wake-up receiver remains on.

Specifically, the first terminal device is in a first state when receiving the first resource indication information from the network device, and is in a second state after being awakened by the first signal when receiving the first signal. In general, when the first terminal device is in the first state, signals other than the first signal are not received or transmitted.

Alternatively, the first terminal device may receive the first resource indication information from the network device through the primary receiver.

Alternatively, 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 Shift Keying (ASK) or Frequency Shift Keying (FSK) modulation.

Alternatively, the number of the first terminal devices may be one or more, and when there are a plurality of first terminal devices, the network device may send first resource indication information corresponding to each of the plurality of first terminal devices, where each first terminal device receives the first signal on the first frequency domain resource indicated by the first resource indication information.

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

The embodiments of the present application provide the following two possible implementations to exemplarily describe the configuration of the first frequency domain resource.

Mode one: dividing a frequency domain resource corresponding to a transmission bandwidth of the first terminal device into a plurality of frequency domain units, wherein the first resource indication information indicates at least one first frequency domain unit in the plurality of 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 of the plurality of frequency domain units may be predefined in the network device and/or the first terminal device; or may be preconfigured, e.g. when the bandwidth of each frequency domain unit is predefined only in the network device, the network device may send signalling 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 bandwidths of each frequency domain unit may be the same or different, which is not limited in this application.

For example, the division of the second frequency domain resource may be from the first frequency domain position, and the division is performed according to a preset bandwidth, so as to obtain a plurality of frequency domain units.

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

The first frequency domain location may be, for example, a starting location of the second frequency domain resource or 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. Alternatively, the first frequency domain location may be a common reference point (e.g., point a).

Assuming that the first frequency domain location is a common reference point other than the second frequency domain resource, as shown in fig. 8a, from this common reference point, the frequency domain is divided according to a preset bandwidth, resulting in a plurality of frequency domain units (0 to 3) corresponding to the second frequency domain resource of the first terminal device 1. Starting from the common reference point, dividing the frequency domain according to a 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, if part of the frequency domain resources in the

frequency domain units

4 and 0 do not overlap with the frequency domain resource of the first terminal device 2, the plurality of frequency domain units corresponding to the second frequency domain resource of the first terminal device 2 do not include the

frequency domain units

4 and 0, or the plurality of frequency domain units corresponding to the second frequency domain resource of the first terminal device 2 include the

frequency domain units

4 and 0, and only the frequency domain resources overlapping with the frequency domain resource of the first terminal device 2 are included in the

frequency domain units

4 and 0.

Assuming that the first frequency domain location is a starting location of the second frequency domain resource, as shown in fig. 8b, frequency domains are divided according to a preset bandwidth from the starting location of the second frequency domain resource, so as to obtain a plurality of frequency domain units (0 to 3) corresponding to the second frequency domain resource of the first terminal device.

Optionally, the plurality of frequency domain units obtained by dividing the second frequency domain resource are not overlapped.

When the first frequency domain position is a common reference point outside the second frequency domain resource, the network device may multiplex first signals of different first terminal devices in the same first frequency domain unit, and send corresponding first signals to each first terminal device. 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, respectively. The utilization rate of the frequency domain resource is improved.

All or part of the plurality of frequency domain units may be at least one first frequency domain unit. When all of the plurality of frequency domain units are at least one first frequency domain unit, that is, each of the plurality of 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 plurality of frequency domain units. For example, the first resource indication information may indicate an identity (such as an index) of each frequency domain unit in the plurality of frequency domain units, and as shown in fig. 8a, the first resource indication information received by the first terminal device 1 may include identities of frequency domain units 0 to 3, and the first resource indication information received by the first terminal device 2 may include identities of frequency domain units 0 to 4, for example; for another example, the first resource indication information may indicate that the plurality of frequency domain units are all the first frequency domain units through 1 bit. In other embodiments, the network device may not send the first resource indication information to the first terminal device, where the first terminal device uses the plurality of frequency domain units obtained by dividing according to the predefined rule as at least one first frequency domain unit, and on the basis of this, the network device may indicate to the first terminal device that one frequency domain unit of the plurality of frequency domain units is used to determine the transmission position of the first signal.

When a part of the frequency domain units in the plurality of 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 therein.

As an example, the first resource indication information includes at least one first indication information for indicating an identity (e.g., 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, the

frequency domain units

1 and 3 in the plurality of frequency domain units are at least one first frequency domain unit.

As another example, the first resource indication information includes a first bitmap having bits corresponding one-to-one to a plurality of 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 one bit of the first bitmap is the second value, the corresponding frequency domain unit is indicated to be the first frequency domain unit, and when one bit of the first bitmap is the third value, the corresponding frequency domain unit is indicated to be not the first frequency domain unit. Wherein the second value may be, for example, 0 and the third value may be, for example, 1; or the second value may be, for example, 1 and the third value may be, for example, 0. Assuming a second value of 1 and a third value of 0, see table 4 below.

TABLE 4 Table 4

Bits	1	1	1	0
					Frequency domain unit	0	1	2	3

Referring to fig. 8b, according to the bitmap shown in table 4,

frequency domain units

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

In the first aspect, the transmission bandwidth of the first terminal device may be a downlink BWP or a downlink carrier bandwidth. The downstream BWP may include one of: BWP of the first terminal device for receiving the first signal; initial downlink BWP; activating downlink BWP; default (default) downstream BWP.

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

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

Alternatively, 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 identification of a transmission bandwidth corresponding to the at least one first frequency domain resource. The at least one first frequency domain resource may correspond to an identification of the same transmission bandwidth, and the at least one first frequency domain resource may also correspond to an identification of a different transmission bandwidth, e.g., the transmission bandwidth indication information may be a BWP identification, and/or a carrier identification.

It is understood that the transmission bandwidth indication information may be carried by the first resource indication information or the transmission bandwidth indication information may be separate indication information.

Mode two: the first resource indication information indicates a first frequency domain resource in a transmission bandwidth of the first terminal device.

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

Before this, the network device needs to determine the start position RB of the first frequency domain resource according to the indication _start Sum bandwidth L _RBS RIV is generated. For example, the network device mayTo a bandwidth L of the first frequency domain resource _RBS And the transmission bandwidth of the first terminal device is

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

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

Wherein L is _RBS Greater than or equal to 1 and less than

The terminal device may determine the starting position and the bandwidth of the first frequency domain resource according to the RIV in the received second indication information. For example, the terminal device may transmit a request for a request to the first terminal device

When the following formula (6) is satisfied, the starting position RB of the first frequency domain resource is determined according to the following formulas (7 a) and (7 b) _start Sum bandwidth L _RBS The transmission bandwidth at RIV and the first terminal device is +.>

Not satisfy the following common formulaIn the case of equation (6), the start position RB of the first frequency domain resource is determined according to the following equations (8 a) and (8 b) _start Sum bandwidth L _RBS 。

The transmission bandwidth of the first terminal device according to the second aspect is already described in the first aspect, and will not be described here again.

In the second mode, the network device realizes efficient configuration of at least one first frequency domain resource by the RIV coding mode, and signaling overhead is saved.

Fig. 7b is an interaction flow diagram of a communication method 300b according to an embodiment of the present application. As shown in fig. 7a, the method 300b includes:

and S310b, the network equipment respectively sends first resource indication information to the first terminal equipment and the second terminal equipment.

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 a 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 embodiment shown in fig. 7b differs from the embodiment shown in fig. 7a in that: in 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 S310b, the network device may further send the first resource indication information to the second terminal device.

In S310b, the process of sending the first resource indication information to the first terminal device by the network device is similar to S310a in fig. 7a, and is not 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 is not described herein.

In S320b, the second terminal device and the first terminal device determine, based on the first resource indication information sent by the network device, a first frequency domain resource for transmitting the first signal, so as to implement transmission of the first signal by the second terminal device and the first terminal device on the first frequency domain resource.

In the embodiment shown in fig. 7a and fig. 7b, the network device configures a plurality of first frequency domain resources to the first terminal device (or to the first terminal device and the second terminal device), when the network device needs to send first signals to the plurality of first terminal devices, the network device may send the first signals to the corresponding first terminal device on each first frequency domain resource, so as to reduce paging false alarm (UE overhead) or improve paging capacity (gNB overhead).

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

In some embodiments, the first signals may be transmitted on the first frequency domain resource, however, when the network device needs to send its respective first signals to the plurality of first terminal devices, in order to ensure that the data transmission efficiency is improved, the plurality of first signals may be frequency division multiplexed, in other words, the network device may send each first signal through a different first frequency resource. As mentioned above, the first signal is used as a wake-up signal or wake-up frame, and the first terminal device usually uses incoherent detection (e.g. envelope detection) for listening to the first signal. In order to avoid interference between the signals, a certain guard band (or guard band) needs to be reserved between the first signals. Referring to fig. 8c, the bandwidth of the first signal of each terminal device (e.g., 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.

Alternatively, the relative position of the first signal in the first frequency domain resource may be configured by the network device, the first frequency domain resource being used to carry 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 NR existing resource allocation, in this embodiment the resource location of the first frequency domain resource (e.g. the starting location and/or the ending location of the first frequency domain resource) and/or the bandwidth of the first frequency domain resource needs to meet a constraint that is an integer multiple of the first value. Wherein the first value is determined based on n first parameters, n being a positive integer.

Illustratively, 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 a least common multiple or a greatest common divisor of the values of the n first parameters. In another example, when n is 2, the first value may be a larger value or a smaller value of the values of the n first parameters, and in yet another example, when n is greater than 2, the first value may be a maximum value or a minimum value of the values of the n first parameters.

The n first parameters may for example comprise at least one of:

the granularity of the frequency domain configuration of the downlink reference signal (e.g., CSI-RS) of the second frequency domain resource, e.g., the granularity of the frequency domain configuration of CSI-RS is 4RB;

the frequency domain configuration granularity of the control resource set of the second frequency domain resource, which has been described above, 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 PDSCH downlink data resources as described above may be, for example, 2, 4, 6, 8, 16 RBs;

the bandwidth supported by the wake-up receiver of the first terminal device may be, for example, 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 may also be the value of the bandwidth;

the first terminal device wakes up a center frequency point of a radio frequency filter of the receiver.

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 acquired by the network device from the capability information reported by the first terminal device.

The above-mentioned limitations to be met by the resource location of the first frequency domain resource (e.g. the starting location and/or the ending location of the first frequency domain resource) and/or the bandwidth of the first frequency domain resource may reduce the impact of the first frequency domain resource for carrying the first signal on the allocation of NR existing resources (e.g. resources of the control resource set, the downlink reference signal, the downlink data resource), with fewer resource fragments. An exemplary description is provided below in connection with fig. 8 d.

Referring to fig. 8d, assuming that the bandwidth of the first frequency domain resource is 6RB, the first frequency domain resource may coincide with one frequency domain resource in the control resource set, on the basis that the first frequency domain resource should be made to coincide with one frequency domain resource in the control resource set, and the first frequency domain resource should be prevented from being made to span multiple frequency domain resources in the control resource set.

Optionally, the above-mentioned limitation to be met by the resource location of the first frequency domain resource (e.g. the starting location and/or the ending location of the first frequency domain resource) and/or the bandwidth of the first frequency domain resource may be protocol-defined or implemented by the network device.

Some or all of the steps of fig. 9 may be included on the basis of fig. 7a or 7b described above.

To avoid the impact of the first signal on the NR common signal, the frequency domain resources of the first signal should be configured away from the frequency domain resources where the SSB and/or CORESET 0 of NR are located.

For example, in one configuration, the transmission bandwidth associated with the first signal does not include SSB and/or the transmission bandwidth associated with the first signal does not include CORESET 0. Note 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 transmission bandwidth indication information.

For example, in another configuration, the transmission bandwidth associated with the first signal includes SSB, the first signal is configured on a side of the transmission bandwidth that is distant from SSB in the frequency domain, f1 is a distance between a lowest frequency position of the transmission bandwidth and SSB, f2 is a distance between a highest frequency position of the transmission bandwidth and SSB, and the first signal should be configured on a side of the transmission bandwidth that is larger than f1 and f 2. And/or the transmission bandwidth associated with the first signal comprises CORESET 0, the first signal is configured on one side of the transmission bandwidth away from CORESET 0 in the frequency domain, f1 is the distance between the lowest frequency position of the transmission bandwidth and CORESET 0, f2 is the distance between the highest frequency position of the transmission bandwidth and CORESET 0, and the first signal should be configured on the larger side of f1 and f2 in the transmission bandwidth. The transmission bandwidth associated with the first signal is determined according to the transmission bandwidth indication information.

Fig. 9 is a schematic interaction flow chart of a communication method 400 provided in an embodiment of the present application. All or part of the steps S410, S440 to S460 shown in fig. 9 may be implemented on the basis of the embodiments shown in fig. 7a or 7b described above, and fig. 9 is only exemplarily described in conjunction with fig. 7a for ease of understanding.

S420 and S430 in fig. 9 are similar to S310a and S320a in fig. 7a, respectively, and are not described here again.

In the first and second modes, the number 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, at the first frequency domain resource, a first signal sent by the network device. If the first resource indication information indicates a plurality of (including two) first frequency domain resources, the first terminal device may determine a third frequency domain resource for carrying the first signal from among the at least one first frequency domain resource, that is, S440 in fig. 9.

The first terminal device determining a third frequency domain resource for carrying the first signal from the at least one first frequency domain resource may comprise two possible examples:

Example one: the network device configures third frequency domain resources 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 (e.g., an index) of a third frequency domain resource, and correspondingly, the first terminal device receives the third resource indication information sent by the network device. Wherein each first frequency domain resource corresponds to an index (value).

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

Example two: the first terminal device determines a third frequency domain resource according to a predefined rule. The following 4 possible implementations may be specifically included.

The implementation mode is as follows: the first terminal equipment determines a third frequency domain resource according to the identification and the number of the first frequency domain resources configured by the network equipment.

For example, the first terminal device may determine the third frequency domain resource according to the following formula (9), i.e. determine that the at least one first frequency domain resource is identified as Q ₁ Is allocated to the first frequency domain resource of the mobile station.

Q ₁ ＝UE_ID mod N _WUR (9)

Assuming that the network device is in communication connection with N first terminal devices, the identifiers ue_id of the N first terminal devices are sequentially 1, 2 … N, and the number N of the first frequency domain resources _WUR =5, then, when ue_id is 1, the third frequency domain resource is the identity Q ₁ First frequency domain resource of=1, when ue_id is 2, third frequency domain resource is identification Q ₁ First frequency domain resource of=2, and so on.

The implementation mode II is as follows: and the first terminal equipment determines a third frequency domain resource according to the service type and a first corresponding relation between the service type and the first frequency domain resource identifier.

By way of example, traffic types may include reduced capability (reduced capability, REDCAP), enhanced mobile bandwidth (enhanced mobile broadband, eMBB), internet of things or non-internet of things, and so forth.

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, the non-internet of things terminal corresponds to the first frequency domain resource 2, and the like. Assuming that the service type of the first terminal device is REDCAP, the third frequency domain resource is a first frequency domain resource 1 of the at least one first frequency domain resource.

And the implementation mode is three: and the first terminal equipment determines a third frequency domain resource according to the paging probability and a second corresponding relation, wherein the second corresponding relation is the corresponding relation between the paging probability and the first frequency domain resource identifier.

For example, in the second correspondence, one paging probability value may correspond to one first frequency domain resource identifier, or one paging probability interval may correspond to one first frequency domain resource identifier. In general, the paging probability intervals do not overlap. If 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, the third frequency domain resource of the first terminal device is the first frequency domain resource 2 of the at least one first frequency domain resource.

The implementation mode is four: and the first terminal equipment determines a third frequency domain resource according to the identification and the weight corresponding to each first frequency domain resource in the at least one first frequency domain resource.

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

Ue_id mod W < W (0) +w (1) + … +w (i) minimum i (10)

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

If assuming that m=4, W (0) =1, W (1) =2, W (2) =3, W (3) =4, W (4) =5, then w=15, if ue_id is 0, then when i=0, ue_id mod w=0, W (0) =1, the above formula (10) holds, then the third frequency domain resource of the first terminal device 0 is the first frequency domain resource 0 of the at least one first frequency domain resource; assuming that ue_id is 1, when i=0, ue_id mod w=1, W (0) =1, the above equation (10) is not satisfied, and when i=1, ue_id mod w=1, W (0) +w (1) =3, and the above equation (10) is satisfied, the point frequency domain resource of the first terminal device 1 is the first frequency domain resource 1 of the at least one first frequency domain resource.

It may be appreciated that, in the above second example, if the second terminal device is a wake-up transmitting end device of the first terminal device, the second terminal device may determine the third frequency domain resource according to any one of the above first to fourth implementations.

It should be noted that the ue_id in the above implementation may be an abbreviation of 5G-S-TMSI mod 1024,5G-S-TMSI of 5GS-Temporary Mobile Subscription Identifier. If the first or second terminal device does not have a 5G-S-TMSI, e.g. the first or second terminal device has not been registered to the network, the first or second terminal device should use a default ue_id=0. In the above implementation manner, the ue_id may also be other identifiers allocated by the network device, which are used to distinguish the terminal device from the terminal device when receiving the first signal, where the value range may be less than or equal to 1024, and the network device may be an access network device or a core network device.

Note that mod is a mathematical operation sign in the above implementation, which represents a remainder operation, for example, a mod b=c, and the remainder of dividing a by b is c.

The first terminal device may transmit the first signal on the third frequency domain resource determined in S440 above, which may be transmitted by the network device or transmitted by the second terminal device as previously described.

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 the signals, a certain guard band (or guard band) needs to be reserved between the first signals. Based on this, the bandwidth of the first signal may be less 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 location of the first signal in the third frequency domain resource (e.g., the bandwidth of the first signal and/or the location of the center frequency point) may be predefined or configured by the network device.

Referring to S450 in fig. 9, the network device may transmit second resource indication information to the first terminal device, where the second resource indication information is used to indicate a resource location of the first signal in the first frequency domain resource (e.g., a bandwidth of the first signal and/or a location of a center frequency point). It may be appreciated that, after the first terminal device determines the third frequency domain resource, the second resource indication information is used to indicate a resource location of the first signal in the third frequency domain resource.

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

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

Referring to fig. 9, in S410, a first terminal device transmits capability information to a network device, and accordingly, the network device receives the capability information transmitted by the first terminal device.

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

whether the first terminal device supports waking up the receiver;

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

Alternatively, this S410 may be performed, for example, before S420 of the embodiment shown in fig. 9.

The network device may determine, according to the capability information reported by the first terminal device, whether to configure at least one first frequency domain resource for the first terminal device, for example, if the capability information indicates that the first terminal device supports waking up the receiver, the network device sends at least one of the first resource indication information, the second resource indication information, and the third resource indication information to the first terminal device.

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

Alternatively, the first terminal device may send the capability information through the primary receiver.

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

In order to reduce the influence of the first frequency domain resource for carrying the first signal on the NR existing resource allocation, the resource location of the first frequency domain resource (e.g., the start location and/or the end location of the first frequency domain resource) and/or the bandwidth of the first frequency domain resource in this embodiment needs to satisfy the constraint of an integer multiple of the first value. The first value has been described in the foregoing examples, and will not be described here again.

Therefore, in the embodiment of the present application, the first terminal device may determine, by receiving the first resource indication information sent by the network device, a first frequency domain resource for carrying the first signal, and receive, on the first frequency domain resource, the first signal for waking up itself, and based on this, the embodiment of the present application provides an effective solution for how the first terminal device determines the frequency domain resource carrying the signal for waking up itself, so that the first terminal device can wake up in each communication system (for example, an NR communication system).
