Description

Resource indication method, related device and system

Technical field

The present invention relates to the field of communications technologies, and in particular, to a resource indication method, related device, and system.

Background technique

The Cellular-based Narrow Band Internet of Things (NB-IoT) standard was officially announced in September 2015 by the 3rd Generation Partnership Project (English: 3rd Generation Partnership Project, 3GPP). NB-IOT is an emerging technology that can be widely used in the world, focusing on the Low Power Wide Area (LPWA) Internet of Things (English: Internet Of Things, referred to as: IOT) market. It has wide coverage, many connections, low speed, low cost, low power consumption, excellent architecture, etc. It can be widely used in vertical industries such as remote meter reading, asset tracking, intelligent parking, and smart agriculture.

NB-IoT defines many resource units for uplink data transmission of 15 kHz subcarriers, and is no longer limited to the resource unit of {12 subcarriers, 1 millisecond} defined in Long Term Evolution (LTE). Flexible allocation of time-frequency resources of various resource units. As shown in FIG. 1, the resource units defined in NB-IoT include: {1 subcarrier, 8 millisecond} resource unit 101, {3 subcarriers, 4 milliseconds} resource unit 102, {6 subcarriers, 2 milliseconds} Resource unit 103 and {12 subcarriers, 1 millisecond} resource unit 104,

The uplink scheduling signaling in the LTE allocates a time-frequency resource whose resource unit is {12 subcarriers, 1 millisecond} to the user equipment (English: User Equipment, abbreviated as UE) by indicating the frequency domain start point and the frequency domain length. The UE receives the time-frequency resource. After the uplink scheduling signaling, the frequency domain starting point and the frequency domain length indicated in the uplink scheduling signaling are parsed, and then the time domain starting point is determined according to a calculation method for calculating a time domain starting point defined in a communication protocol between the UE and the uplink device, where The time domain length of each time-frequency resource defined by the communication protocol defaults to 1 millisecond; the UE combines the frequency domain start point, the time domain start point, the frequency domain length, and the time domain length to determine that the resource unit allocated to itself is {12 children. Carrier, 1 ms} time-frequency resource.

A disadvantage of the prior art is that the UE can be divided into the UE by indicating the start of the frequency domain and the length of the frequency domain. A time-frequency resource with a resource unit of {12 subcarriers, 1 millisecond} cannot allocate time-frequency resources of multiple resource units defined in the NB-IoT.

The technical solutions in the embodiments of the present invention will be clearly and completely described in the following with reference to the accompanying drawings. The reference terminal described in the embodiment of the present invention is a terminal device capable of performing uplink scheduling, such as a base station. The target terminal described in this embodiment of the present invention is capable of receiving target signaling (the target signaling may also be referred to as an actual application). A terminal device that performs uplink data transmission based on the target signaling, for example, a handheld device with an wireless communication function, an in-vehicle device, a wearable device, a computing device, or Other processing devices connected to the wireless modem, and various forms of user equipment (English: User Equipment, UE for short), mobile station (English: Mobile station, MS for short) and the like.

Referring to FIG. 2, FIG. 2 is a schematic flowchart diagram of a resource indication method according to an embodiment of the present invention. The first implementation based on the flow diagram shown in Figure 2 is as follows:

Step S201: The reference terminal sends the target signaling to the target terminal.

The frequency domain length and time domain length of the time-frequency resource. The target signaling further indicates determining a frequency domain length and a time domain length of the target time-frequency resource based on one of the preset multiple resource units, where the multiple resource units may include {1 subcarrier, 8 milliseconds} , {3 subcarriers, 4 milliseconds}, {6 subcarriers, 2 milliseconds} and {12 subcarriers, 1 millisecond}. Assuming that the time-frequency length of the target time-frequency resource is determined by the time-frequency length of {3 sub-carriers, 4 milliseconds}, the specific manner of determining may be: The sub-carrier, the frequency domain length of 4 milliseconds is used as the frequency domain length of the target time-frequency resource, and the time domain length of {3 sub-carriers, 4 milliseconds} is taken as the time-domain length of the target time-frequency resource; The frequency domain length of {3 subcarriers, 4 milliseconds} is taken as the frequency domain length of the target time-frequency resource, and X times of the time domain length of {3 subcarriers, 4 milliseconds} is taken as the time domain length of the target time-frequency resource, X A predetermined amount in a communication protocol of the reference terminal and the target terminal, or an amount indicated by the target signaling.

In an optional solution, the target signaling may include two types of information, where one information is used to indicate the starting point of the frequency domain, may be represented by a specific frequency value, or may be corresponding to a frequency value by a preset setting. Another identifier is used to indicate the target resource unit in the foregoing multiple resource units, and may be represented by two dimensions of the time domain length and the frequency domain length, or may be preset by the target resource. The unit corresponds to the identifier to indicate. Further, the resource unit {1 subcarrier, 8 milliseconds}, {3 subcarriers, 4 milliseconds}, {6 subcarriers, 2 milliseconds}, and {12 subcarriers, 1 millisecond} may also respectively correspond to their own resource unit identifiers. The target signaling may indicate which resource unit is the target resource unit by the resource unit identifier.

In an optional solution, the target signaling may indicate a time domain starting point in addition to indicating a frequency domain starting point and a time-frequency length, and may pass a specific time domain value (or indicate a reference value for reference calculation). The representation may also be represented by a predetermined identifier corresponding to the time domain value.

If the target signaling indicates the start of the time domain, there are several implementation modes as follows:

The first mode: the target signaling includes a first identifier, where the target signaling indicates, by using the first identifier, a frequency domain start point and a time domain start point of the target time-frequency resource, and the preset frequency domain start point and time Each combination of the starting points of the domain corresponds to a respective first identification.

Optionally, refer to the schematic diagram of the preset resource block shown in FIG. 3. The resource block has a specification of {12 subcarriers, 8 milliseconds}, where each minimum square size is {1 subcarrier, 1 millisecond}. That is, the frequency domain length of each minimum square is 1 subcarrier, and the time domain length is 1 millisecond. Each of the smallest squares in the same column in FIG. 3 has the same time domain and different frequency domains, and each of the smallest squares of the same has the same Frequency domain and different time domain, each minimum square of different rows has different frequency domains; each minimum square in the preset resource block has a unique combination of a frequency domain start point and a time domain start point, which can be given Each combination has a unique first identifier, such that each first identifier implies two pieces of information, one for the frequency domain Point, one is the time domain starting point; in the embodiment of the present invention, the target signaling indicates the frequency domain starting point and the time domain starting point of the scheduled target time-frequency resource by using the first identifier.

In still another optional solution, the target signaling indicates determining a frequency domain length and time of the target time-frequency resource according to a frequency domain length and a time domain length of the target resource unit in the preset multiple resource units. The domain length includes:

The target signaling indicates that X times of the time domain length of the target resource unit in the preset multiple resource units is used as the time domain length of the target time-frequency resource, and Y of the frequency domain length of the target resource unit As the frequency domain length of the target time-frequency resource, X and Y are both natural numbers.

Or the target signaling indicates that the time domain length of the target resource unit in the preset multiple resource units is used as the time domain length of the target time-frequency resource, and Y times of the frequency domain length of the target resource unit is used as The frequency domain length of the target time-frequency resource, and Y is a natural number.

Or the target signaling indicates that X times of the time domain length of the target resource unit in the preset multiple resource units is used as the time domain length of the target time-frequency resource, and the frequency domain length of the target resource unit is used as the The frequency domain length of the target time-frequency resource, and X is a natural number.

Specifically, when the time-frequency length of the target time-frequency resource is related to X, X may be a pre-defined value in a protocol shared by the reference terminal and the target terminal, or may be a value carried in the uplink scheduling; When the time-frequency length of the frequency resource is related to Y, Y may be a pre-defined value in the protocol shared by the reference terminal and the target terminal, or may be a value carried in the uplink scheduling; when the time-frequency length of the target time-frequency resource When X and Y are related, X and Y may be pre-defined values in a protocol shared by the reference terminal and the target terminal, and may also be values carried in the uplink scheduling; of course, X and Y used may also pass other The way to indicate.

When the target signaling indicates that X times of the time domain length of the target resource unit in the preset multiple resource units is used as the time domain length of the target time-frequency resource, the frequency domain length of the target resource unit is used as When the frequency domain length of the target time-frequency resource is assumed, the target resource unit indicated by the target signaling is {6 subcarriers, 2 milliseconds}, and the indicated X is 2, then according to the target resource unit {6 subcarriers, 2 milliseconds} and X can determine that the target time-frequency resource has a frequency domain length of 6 subcarriers, and the time domain length is 2*2=4 milliseconds, that is, {6 subcarriers, 4 milliseconds}.

When the target signaling indicates that the time domain length of the target resource unit in the preset multiple resource units is the time domain length of the target time-frequency resource, and Y times of the frequency domain length of the target resource unit is used as When the frequency domain length of the target time-frequency resource is assumed, the target resource unit indicated by the target signaling is {6 subcarriers, 2 milliseconds}, and the indicated Y is 2, then the frequency domain length of the target time-frequency resource is obtained. 6*2=12 subcarriers, the time domain length is 2 milliseconds, that is, {12 subcarriers, 2 milliseconds};

The rest of the situation can be analogized by analogy.

Further, as an optional solution, the target signaling includes a second identifier, where the target signaling indicates, by using the second identifier, the target resource unit and X, a preset resource unit type and a multiple Each combination corresponds to a respective second identification.

Specifically, due to a resource block in a given preset resource block ({12 subcarriers, 8 milliseconds} as shown in FIG. 3), the target time-frequency resources obtained by adding the plurality of target resource units are in the The situation within a preset resource block is limited, so all cases can be enumerated in an exhaustive manner, and then each case is given a unique second identity. For example, when multiple target resource units are added and added in time domain, {1 subcarrier, 8 milliseconds} can only be 1 in a preset resource block {12 subcarriers, 8 milliseconds}. For a plurality of times, the range of the preset resource block is exceeded, that is, the value of the number X is 1; {3 subcarriers, 4 milliseconds} can be up to 2 in the preset resource block {12 subcarriers, 8 milliseconds} Adding, the frequency domain length and time domain length obtained by adding 2 are {3 subcarriers, 8 milliseconds}, that is, the value of the number X is 1 or 2; {6 subcarriers, 2 milliseconds} in the preset resource block The maximum number of frequency domain lengths and time domain lengths of {12 subcarriers, 8 milliseconds} is {6 subcarriers, 8 milliseconds}, that is, the value of the number X is 1 to 4. The natural number between; {12 subcarriers, 1 millisecond} can be up to 8 additions in the preset resource block {12 subcarriers, 8 milliseconds}, and the frequency domain length and time domain length obtained by 8 additions are { 12 subcarriers, 8 milliseconds}, that is, the number X is a natural number between 1 and 8; refer to Table 1, which lists each case in Table 1, each case corresponding to a unique second identifier.

Table 1

It can be seen from Table 1 that the target resource unit and X can be specifically represented by the second identifier. For example, when the second identifier included in the uplink scheduling is 13, the target resource unit of the uplink scheduling indication is {12 subcarriers, 1 millisecond. }, and the indication X is specifically 6.

Step S202: The target node receives the target signaling.

Step S203: The target terminal parses the target signaling, and determines a target time-frequency resource based on a frequency domain starting point indicated by the target signaling, and a frequency domain length and a time domain length of the indicated target resource unit.

Specifically, after receiving the target signaling, the target terminal parses the target signaling, for example, decoding, demodulating, etc., and obtains information included therein for indicating a frequency domain start point and a time-frequency length, if the target signal If the time domain starting point is also indicated in the command, the target terminal may also parse the information indicating the starting time of the time domain. In the embodiment of the present invention, for the case where the parsed target signaling does not indicate the time domain starting point, the The target terminal may use the time domain of the time-frequency resource occupied by the reference terminal to transmit the target signaling as a reference, and use the Nth millisecond (or subframe) after the time domain as the time domain starting point, N. For a natural number, the N may be a predefined number of communication protocols of the reference terminal and the target terminal, and the N may also be a quantity that the reference terminal sends to the target terminal by using target signaling, and the N may also be m. And n, m and n are both natural numbers, where m is a predefined number of communication protocols of the reference terminal and the target terminal or a quantity calculated according to a calculation rule defined in the communication protocol, n is the reference The terminal indicates to the target terminal a quantity by the target signaling.

It should be noted that the specific meaning of the first identifier (if any) and the second identifier (if any) are predefined in the communication protocol between the reference terminal and the target terminal, and the target signaling passes the first identifier. When the frequency domain start point and the time domain start point are indicated, the target terminal may also correspondingly analyze the frequency domain start point and the time domain start point indicated by the first identifier, and when the target signaling indicates the time-frequency length and the X by the second identifier The target terminal can correspondingly analyze the time-frequency length and X indicated by the second identifier.

When the target terminal analyzes the starting point of the frequency domain indicated in the target signaling, the starting point of the time domain (which may also be derived according to the definition of the protocol) and the time-frequency length, according to the starting point of the frequency domain, the starting time of the time domain (may also The target time-frequency resource indicated by the target signaling is determined according to the definition of the protocol and the time-frequency length.

Step S204: The target terminal transmits uplink data by using the target time-frequency resource.

In the first method embodiment corresponding to FIG. 2, when the reference terminal sends the target signaling to allocate time-frequency resources to the target terminal, the target frequency signaling indicates the target of the frequency domain and the target resource unit of the multiple resource units. (the indicated resource unit is the target resource unit) to the target terminal, the terminal receives the target signaling, and parses out the frequency domain starting point indicated in the target signaling, the frequency domain length of the target resource unit, and the target resource unit. The time domain length and the time domain start point (which may be determined for the target signaling may also be determined according to an algorithm defined in the communication protocol) determine the scheduled time-frequency resource, and in this way, the target terminal may be allocated the multiple The time-frequency resource of any resource unit in the resource unit.

The second implementation based on the flow diagram shown in Figure 2 is as follows:

Specifically, the target signaling includes an identifier, where the target signaling is used to indicate that the target terminal determines the allocated time-frequency resource based on the target time-frequency resource corresponding to the identifier, and presets the multiple time-frequency resources. Each of the time-frequency resources is associated with the identifier of each of the time-frequency resources, and the target time-frequency resource is one of the plurality of time-frequency resources. Optionally, the multiple resource units may be {1 subcarrier, 8 milliseconds}, {3 subcarriers, 4 milliseconds}, {6 subcarriers, 2 milliseconds}, and {12 subcarriers, 1 millisecond}.

The following uses the preset resource block shown in FIG. 3 as an example to explain the meaning of each of the preset time-frequency resources corresponding to the identifier of each of the time-frequency resources. There are 12 kinds of resource units of {1 subcarrier, 8 milliseconds} in the preset resource block, and 8 resource elements of {12 subcarriers and 1 millisecond} are distributed in the preset resource block. There are 50 kinds of resource units of {3 subcarriers, 4 milliseconds} in the preset resource block, and there are 49 kinds of resource units of {6 subcarriers and 2 milliseconds} in the preset resource block. That is, there are a total of 119 types of resource units in a preset resource block, and each mode can be given a unique identifier, so that the time-frequency resources corresponding to each distribution mode can be represented by the identifier.

In an optional solution, the target signaling is used to indicate that the target terminal uses the target time-frequency resource corresponding to the identifier as the allocated time-frequency resource. That is to say, the frequency domain start, the time domain start, the frequency domain length and the time domain length of the allocated time-frequency resource are the same as the frequency domain start, the time domain start, the frequency domain length and the time domain length of the target time-frequency resource. .

In still another optional solution, the target signaling includes a quantity identifier K, and the target signaling is used to indicate that the target terminal is the frequency domain starting point of the target time-frequency resource corresponding to the identifier. a frequency domain start point of the allocated time-frequency resource, a time domain start point of the target time-frequency resource is a time domain start point of the allocated time-frequency resource, and a frequency domain length of the target time-frequency resource is used as the The frequency domain length of the allocated time-frequency resource, the time domain length of the K target frequency-frequency resources is used as the time domain length of the allocated time-frequency resource, and K is a natural number.

Specifically, if the time-frequency length of the target time-frequency resource corresponding to the identifier is {6 subcarriers, 2 milliseconds}, and the number identifier K is equal to 2, the time domain starting point of the allocated time-frequency resource is the same The time domain starting point of the time-frequency resource is the same, the frequency domain starting point of the allocated time-frequency resource is the same as the frequency domain starting point of the target time-frequency resource, and the allocated time-frequency resource has a time domain length of 2*2=4 In milliseconds, the frequency domain length of the allocated time-frequency resource is 6 subcarriers. In addition, the quantity identifier 6 may also be a pre-defined number in the communication protocol between the reference terminal and the target terminal, so that the quantity identifier K does not need to be indicated in the target signaling.

For the foregoing possible implementation, the frequency domain length of any one of the preset time-frequency resources is an integer multiple of the frequency domain length of one of the preset multiple resource units. The time domain length of any one of the time-frequency resources is an integer multiple of the time domain length of the one resource unit.

For example, if the multiple resource units are {12 subcarriers, 1 millisecond} and {3 subcarriers, 4 milliseconds}, the frequency domain length of the time-frequency resource in the preset multiple time-frequency resources is 12 sub-lengths. An integer multiple of the carrier or an integer multiple of three subcarriers, and the time domain length of the time-frequency resources in the plurality of time-frequency resources is an integer multiple of 1 millisecond or an integer multiple of 4 milliseconds. For example, the time-frequency length of the time-frequency resources in the plurality of time-frequency resources may be: {12 sub-carriers, 3 milliseconds}, {3 sub-carriers, 8 milliseconds}.

Step S202: The target node receives the target signaling.

Step S203: The target terminal parses the target signaling, and determines the allocated time-frequency resource based on the target time-frequency resource corresponding to the identifier in the target signaling.

Specifically, after receiving the target signaling, the target terminal parses the target signaling, for example, decoding, demodulating, etc., to obtain an identifier included therein, and if the target signaling further indicates the quantity identifier K, then the target terminal The target terminal may also parse the K; the specific meaning of the identifier and the quantity identifier (if any) is predefined in the communication protocol between the reference terminal and the target terminal, and when the target signaling indicates the time-frequency resource by using the identifier, The target terminal may also correspondingly analyze the time-frequency resource indicated by the identifier (ie, the allocated time-frequency resource).

Step S204: The target terminal transmits uplink data by using the allocated time-frequency resource.

In the second method embodiment corresponding to FIG. 2, an identifier is defined for each time-frequency resource in a communication protocol between the reference terminal and the target terminal, and the reference terminal sends the target signaling to the target terminal to include the target standard, and the target terminal Receiving the target signaling, parsing the identifier in the target signaling, and finding a target time-frequency resource corresponding to the identifier from the communication protocol, and then determining to be adjusted based on the target time-frequency resource. The time-frequency resource of the degree, the resource unit of the time-frequency resource corresponding to each identifier in the communication protocol is not limited, so in this way, the time-frequency resource of various resource units can be allocated to the target terminal.

The third implementation based on the flow diagram shown in Figure 2 is as follows:

Specifically, the target signaling includes a split mode identifier and an area identifier, where the target signaling is used to indicate that the target terminal determines that the target time-frequency resource that is commonly specified by the split mode identifier and the area identifier is allocated. The time-frequency resource, the allocated time-frequency resource is used for the target terminal to transmit uplink data; the preset resource block is divided into multiple regions, and each of the division manners has its own division manner identifier. Each area has its own area identifier, and each divided area in the preset resource block is a time-frequency resource.

It should be noted that the time-frequency resources with the same specifications may exist in the respective regions in which the preset resource blocks are divided, and the time-frequency resources with the same specifications specifically refer to the time-frequency resources with the same frequency domain length and the same time domain length. Each of the division methods has a unique division mode identifier. Each of the division methods has multiple regions, and each region corresponds to its own unique region identifier. Each region has a frequency domain start point, a time domain start point, and a frequency domain. The length and time domain length, that is, each region is a complete time-frequency resource.

The embodiment of the present invention lists two ways of dividing a preset resource block into a plurality of regions by using FIG. 4 and FIG. The division mode corresponding to the division mode shown in FIG. 4 is identified as F1, and the division manner corresponding to the division manner shown in FIG. 5 is identified as F2; and both of FIG. 4 and FIG. 5 include region 1, region 2, region 3, region 4, and region. 5. Region 6, Region 7, and Region 8, and the regions identified by Region 1, Region 2, Region 3, Region 4, Region 5, Region 6, Region 7, and Region 8 are sequentially Q1, Q2, Q3, Q4, and Q5. The Q1, the Q7, the Q7, and the Q8; the target signaling may be used to indicate the time-frequency resource in the preset resource block by using the partitioning mode identifier and the area identifier, for example, the partitioning mode identifier and the area identifier included in the target signaling are ( F1, Q5) indicates the time-frequency resources indicated by the area 5 in the division manner shown in FIG.

In an optional solution, the target signaling is used to indicate that the target terminal uses the target time-frequency resource that the partition mode identifier and the area identifier jointly correspond to as the allocated time-frequency resource. That is to say, the frequency domain start, the time domain start, the frequency domain length and the time domain length of the allocated time-frequency resource and the target time-frequency The frequency domain start, time domain start, frequency domain length, and time domain length of the resource are the same.

In an optional solution, the target signaling includes a quantity identifier T, where the target signaling is used to indicate that the target terminal identifies the target time-frequency corresponding to the area identifier in the partition manner. The frequency domain starting point of the resource is the frequency domain starting point of the allocated time-frequency resource, and the time domain starting point of the target time-frequency resource is the time domain starting point of the allocated time-frequency resource, and the target time-frequency resource is used. The frequency domain length is used as the frequency domain length of the allocated time-frequency resource, and the time domain length of the T target frequency-frequency resources is used as the time domain length of the allocated time-frequency resource, and T is a natural number.

Specifically, it is assumed that the time-frequency length of the target time-frequency resource corresponding to the partition mode identifier and the area identifier is {6 subcarriers, 2 milliseconds}, and the number identifier T is equal to 2, then the allocated time-frequency resource is The time domain starting point is the same as the time domain starting point of the target time-frequency resource, the frequency domain starting point of the allocated time-frequency resource is the same as the frequency domain starting point of the target time-frequency resource, and the allocated time-frequency resource has a time domain length of 2*2=4 milliseconds, the frequency domain length of the allocated time-frequency resource is 6 subcarriers. In addition, the quantity identifier may also be a pre-defined number in the communication protocol between the reference terminal and the target terminal, so that the quantity identifier T does not need to be indicated in the target signaling.

For the above-mentioned possible implementation, the frequency domain length of any one of the preset resource blocks is an integer multiple of the frequency domain length of one of the preset multiple resource units, and the arbitrary one The time domain length of the time-frequency resource is an integer multiple of the time domain length of the one resource unit.

For example, if the multiple resource units are {12 subcarriers, 1 millisecond} and {3 subcarriers, 4 milliseconds}, the frequency domain length of the time-frequency resource in the preset resource block is an integer of 12 subcarriers. The multiple or the integer multiple of 3 subcarriers, and the time domain length of the time-frequency resource in the preset resource block is an integer multiple of 1 millisecond or an integral multiple of 4 milliseconds. For example, the time-frequency length of the time-frequency resource in the preset resource block may be: {12 subcarriers, 3 milliseconds}, {3 subcarriers, 8 milliseconds}. Optionally, the multiple resource units may also be {1 subcarrier, 8 milliseconds}, {3 subcarriers, 4 milliseconds}, {6 subcarriers, 2 milliseconds}, and {12 subcarriers, 1 millisecond}.

Step S202: The target node receives the target signaling.

Step S203: The target terminal parses the target signaling, and determines the allocated time-frequency resource based on the target time-frequency resource corresponding to the division mode identifier and the area identifier in the target signaling.

Specifically, after receiving the target signaling, the target terminal parses the target signaling, for example, decoding, demodulating, etc., and obtains a division mode identifier and an area identifier included therein, if the target signaling further indicates the quantity. The identifier T, the target terminal further parses the T; the division mode identifier, the area identifier, and the quantity identifier (if any) have specific meanings defined in the communication protocol between the reference terminal and the target terminal, when the target letter When the time-frequency resource is indicated by the foregoing division mode identifier and the area identifier, the target terminal may also analyze the time-frequency resource (that is, the allocated time-frequency resource) indicated by the division mode identifier and the area identifier.

In the third method embodiment corresponding to FIG. 2, a division mode identifier and an area identifier are defined for each time-frequency resource in a communication protocol between the reference terminal and the target terminal, and the target terminal sends the target signaling to the target terminal. Defining the mode identifier and the area identifier, the terminal receives the target signaling, parses the partition mode identifier and the area identifier included in the target signaling, and determines, according to the communication protocol, the target time-frequency resource that the partition mode identifier and the area identifier jointly correspond to. And determining, according to the target time-frequency resource, the scheduled time-frequency resource, where the resource unit of the time-frequency resource corresponding to each of the division mode identifier and the area identifier in the communication protocol is not limited, so that various modes can be allocated to the target terminal in this manner. Time-frequency resources of resource units.
