Description

Resource indication method, related equipment and system

Technical Field

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

Background

The cellular-based narrowband Internet of Things (NB-IoT) standard promulgated by the third Generation Partnership Project (3 rd Generation Partnership Project, 3GPP) in 2015 at 9 months. The NB-IOT is a new technology which can be widely applied in the global scope, focuses on the market Of Low Power Wide Area (LPWA) Internet Of Things (IOT), has the characteristics Of Wide coverage, more connections, Low speed, Low cost, less Power consumption, excellent architecture and the like, and can be widely applied to vertical industries such as remote meter reading, asset tracking, intelligent parking, intelligent agriculture and the like.

The NB-IoT defines many resource units for uplink data transmission of the 15kHz subcarrier, and is not limited to the resource unit of {12 subcarriers, 1 millisecond } defined in Long Term Evolution (LTE), so as to more flexibly allocate time-frequency resources of various resource units. As shown in fig. 1, the resource units defined in NB-IoT include: resource unit 101 of {1 subcarrier, 8 msec }, resource unit 102 of {3 subcarriers, 4 msec }, resource unit 103 of {6 subcarriers, 2 msec } and resource unit 104 of {12 subcarriers, 1 msec },

uplink scheduling signaling in LTE allocates time-frequency resources with resource units of {12 subcarriers, 1 millisecond } to User Equipment (UE) by indicating a frequency domain starting point and a frequency domain length, and after receiving the uplink scheduling signaling, the UE parses the frequency domain starting point and the frequency domain length indicated in the uplink scheduling signaling, and then determines a time domain starting point according to a calculation method for calculating a time domain starting point defined in a communication protocol between the UE and the uplink Equipment, where the time domain length of each time-frequency resource defined by the communication protocol is defaulted to 1 millisecond; the UE can determine the time-frequency resource with the resource unit of {12 subcarriers, 1 millisecond } by combining the frequency domain starting point, the time domain starting point, the frequency domain length and the time domain length.

The prior art has the defect that only time-frequency resources with resource units of {12 subcarriers, 1 millisecond } can be allocated to the UE by indicating a frequency domain starting point and a frequency domain length, and time-frequency resources of various resource units defined in NB-IoT cannot be allocated.

Detailed Description

The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. The reference terminal described in the embodiments of the present invention is a terminal device capable of performing uplink scheduling, such as a base station; the target terminal described in the embodiment of the present invention is a terminal device capable of receiving a target signaling (the target signaling may also be referred to as an uplink authorization signaling, an uplink scheduling signaling, downlink control information, and the like in practical applications), and performing uplink data transmission based on the target signaling, for example, a handheld device, a vehicle-mounted device, a wearable device, a computing device, or other processing devices connected to a wireless modem with a wireless communication function, various forms of User Equipment (UE), a Mobile Station (MS), and the like.

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

step S201: and the reference terminal sends the target signaling to the target terminal.

The target signaling in the embodiment of the invention indicates the frequency domain starting point of the target time-frequency resource and indicates that the frequency domain length and the time domain length of the target time-frequency resource are determined according to the frequency domain length and the time domain length of a target resource unit in a plurality of preset resource units. The target signaling further indicates that the frequency domain length and the time domain length of the target time-frequency resource are determined based on one of a plurality of preset resource units, wherein the plurality of resource units may include {1 subcarrier, 8 msec }, {3 subcarriers, 4 msec }, {6 subcarriers, 2 msec } and {12 subcarriers, 1 msec }. Assuming that the time-frequency length of the target time-frequency resource is determined by the time-frequency length of {3 subcarriers, 4 milliseconds }, the specific manner of determining may be: taking the frequency domain length of the {3 subcarriers, 4 milliseconds } as the frequency domain length of the target time frequency resource, and taking the time domain length of the {3 subcarriers, 4 milliseconds } as the time domain length of the target time frequency resource; the following steps can be also included: and taking the frequency domain length of the {3 subcarriers, 4 milliseconds } as the frequency domain length of the target time-frequency resource, taking X times of the time domain length of the {3 subcarriers, 4 milliseconds } as the time domain length of the target time-frequency resource, wherein X is a quantity predefined in a communication protocol between the reference terminal and the target terminal or a quantity indicated by the target signaling.

In an alternative, the target signaling may include two kinds of information, one kind of information is used to indicate the starting point of the frequency domain, and may be represented by a specific frequency value or may be represented by a predetermined identifier corresponding to the frequency value; the other information is used to indicate a target resource unit of the plurality of resource units, and may be represented by two dimensions, i.e., a time domain length and a frequency domain length, or may be represented by a preset identifier corresponding to the target resource unit. Further, the resource units {1 subcarrier, 8 msec }, {3 subcarriers, 4 msec }, {6 subcarriers, 2 msec } and {12 subcarriers, 1 msec } may also respectively correspond to their own resource unit identifiers, and the target signaling may indicate which resource unit is the target resource unit through the resource unit identifiers.

In an optional scheme, the target signaling may indicate a time domain starting point in addition to a frequency domain starting point and a time-frequency length, and may be represented by a specific time domain value (or indicate a reference value for reference calculation), or may be represented by a preset identifier corresponding to the time domain value.

If the target signaling indicates the time domain starting point, there may be several following embodiments:

the first mode is as follows: the target signaling comprises a first identifier, the target signaling indicates a frequency domain starting point and a time domain starting point of the target time frequency resource through the first identifier, and each combination of the preset frequency domain starting point and the preset time domain starting point corresponds to a respective first identifier.

Optionally, please refer to the schematic diagram of the preset resource block shown in fig. 3, where the specification of the resource block is {12 subcarriers, 8 milliseconds }, where each minimum square is {1 subcarrier, 1 millisecond }, that is, the frequency domain length of each minimum square is 1 subcarrier, the time domain length is 1 millisecond, each minimum square in the same column in fig. 3 has the same time domain and different frequency domains, each minimum square in the same row has the same frequency domain and different time domains, and each minimum square in different rows has different frequency domains; each minimum square in the preset resource block is provided with a unique combination of a frequency domain starting point and a time domain starting point, and each combination can be endowed with a unique first identifier, so that each first identifier implies two pieces of information, one is the frequency domain starting point and the other is the time domain starting point; in the embodiment of the invention, the target signaling indicates the frequency domain starting point and the time domain starting point of the scheduled target time frequency resource through the first identifier.

In another optional scheme, the determining, by the target signaling instruction, the frequency domain length and the time domain length of the target time-frequency resource according to the frequency domain length and the time domain length of a target resource unit of preset multiple resource units includes:

the target signaling indicates that X times of the time domain length of a target resource unit in 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, wherein X, Y are all natural numbers.

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

Or the target signaling indicates that the time domain length of the target time frequency resource is X times of the time domain length of a target resource unit in preset multiple resource units, the frequency domain length of the target resource unit is used as 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 predefined 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 target time-frequency resource is related to Y, Y may be a value predefined 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 target time-frequency resource is related to X and Y, X and Y may be predefined values in a protocol shared by the reference terminal and the target terminal, or values carried in the uplink scheduling; of course the X, Y used may be indicated in other ways.

When the target signaling indicates that X times of the time domain length of a target resource unit in 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 frequency domain length of the target time-frequency resource, assuming that the target resource unit indicated by the target signaling is {6 subcarriers, 2 milliseconds }, and the indicated X is 2, then the frequency domain length of the target time-frequency resource can be determined to be 6 subcarriers according to the target resource unit {6 subcarriers, 2 milliseconds } and X, 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 a target resource unit in 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, assuming that the target resource unit indicated by the target signaling is {6 subcarriers, 2 milliseconds }, and the indicated Y is 2, then obtaining that the frequency domain length of the target time-frequency resource is 6 × 2 ═ 12 subcarriers, and the time domain length is 2 milliseconds, namely {12 subcarriers, 2 milliseconds };

the rest of the cases can be analogized, and no examples are given here.

Further, as an optional scheme, the target signaling includes a second identifier, the target signaling represents the target resource unit and the target resource unit X through the second identifier, and each combination of the preset resource unit type and the multiple corresponds to the respective second identifier.

Specifically, since the target time-frequency resource obtained by adding a plurality of target resource units in a given preset resource block (e.g., {12 subcarriers, 8 msec } resource block as shown in fig. 3) is limited in the preset resource block, all cases may be enumerated in an exhaustive manner, and then a unique second identifier is assigned to each case. For example, when the sum of a plurality of target resource units is specifically a time-domain sum, only 1 subcarrier, 8 milliseconds can be added in a preset resource block {12 subcarriers, 8 milliseconds }, and when a plurality of target resource units are added, the number of target resource units exceeds the range of the preset resource block, that is, the value of the number X is 1; {3 subcarriers, 4 milliseconds } can be added by 2 at most in a preset resource block {12 subcarriers, 8 milliseconds }, the frequency domain length and the time domain length obtained by 2 additions are {3 subcarriers, 8 milliseconds }, that is, the value of the quantity X is 1 or 2; at most 4 additions can be made in a preset resource block {12 subcarriers, 8 milliseconds } {6 subcarriers, 2 milliseconds }, the frequency domain length and the time domain length obtained by the 4 additions are {6 subcarriers, 8 milliseconds }, namely the value of the quantity X is a natural number between 1 and 4; at most 8 additions can be made in a preset resource block {12 subcarriers, 8 milliseconds }, the frequency domain length and the time domain length obtained by 8 additions are {12 subcarriers, 8 milliseconds }, namely the value of the quantity X is a natural number between 1 and 8; referring to table 1, each instance is listed in table 1, each instance corresponding to a unique second identifier.

TABLE 1

As can be seen from table 1, the target resource unit and X may be specifically represented by the second identifier, for example, when the uplink schedule includes the second identifier of 13, the target resource unit indicated by the uplink schedule is {12 subcarriers, 1 millisecond }, and the indication X is specifically 6.

Step S202: the target node receives the target signaling.

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

Specifically, after receiving the target signaling, the target terminal analyzes the target signaling, for example, decodes, demodulates, and obtains information included therein for indicating a frequency domain starting point and a time-frequency length, and if the target signaling also indicates a time domain starting point, the target terminal also analyzes to obtain information indicating the time domain starting point; in the embodiment of the present invention, for the case that the parsed target signaling does not indicate the time domain starting point, the target terminal may, as in the prior art, the time domain of the time frequency resource occupied by the reference terminal for sending the target signaling is taken as a reference, the Nth millisecond (or subframe) after the time domain is taken as a time domain starting point, N is a natural number, the N may be a number predefined for a communication protocol between the reference terminal and the target terminal, the N may also be a number sent to the target terminal by the reference terminal through a target signaling, the N may also be composed of m and N, both of which are natural numbers, wherein m is a number predefined by a communication protocol of the reference terminal and the target terminal or a number calculated according to a calculation rule defined in the communication protocol, and n is a number indicated to the target terminal by the reference terminal through the target signaling.

It should be noted that specific meanings of the first identifier (if any) and the second identifier (if any) are predefined in a communication protocol between the reference terminal and the target terminal, when the target signaling indicates a frequency domain starting point and a time domain starting point through the first identifier, the target terminal may also analyze the frequency domain starting point and the time domain starting point indicated by the first identifier, and when the target signaling indicates a time-frequency length and an X through the second identifier, the target terminal may correspondingly analyze the time-frequency length and the X indicated by the second identifier.

After the target terminal analyzes the frequency domain starting point, the time domain starting point (possibly deduced according to the definition of the protocol) and the time-frequency length indicated in the target signaling, the target time-frequency resource indicated by the target signaling is determined according to the frequency domain starting point, the time domain starting point (possibly deduced according to the definition of the protocol), the time-frequency length and the like.

Step S204: and the target terminal transmits uplink data through the target time-frequency resource.

In the first method embodiment corresponding to fig. 2, when the reference terminal allocates a time-frequency resource to the target terminal to send a target signaling, the target signaling indicates a frequency domain starting point and a target resource unit (one indicated resource unit is a target resource unit) in multiple resource units to the target terminal, the terminal receives the target signaling, and parses the frequency domain starting point indicated in the target signaling, the frequency domain length of the target resource unit, the time domain length of the target resource unit, and a time domain starting point (which may be indicated by the target signaling or determined according to an algorithm defined in a communication protocol) to determine a scheduled time-frequency resource, so that the time-frequency resource of any resource unit in the multiple resource units can be allocated to the target terminal.

A second embodiment based on the flow diagram shown in fig. 2 is as follows:

Specifically, the target signaling includes an identifier, where the target signaling is used to instruct the target terminal to determine a time-frequency resource to be allocated based on a target time-frequency resource corresponding to the identifier, where each of a plurality of time-frequency resources is preset to have the identifier of the time-frequency resource, and the target time-frequency resource is one of the time-frequency resources. Optionally, the plurality of resource units may be {1 subcarrier, 8 msec }, {3 subcarriers, 4 msec }, {6 subcarriers, 2 msec } and {12 subcarriers, 1 msec }.

The meaning that each time frequency resource in the multiple time frequency resources corresponds to the identifier of each time frequency resource is explained below by taking the preset resource block shown in fig. 3 as an example. The distribution modes of the resource units of {1 subcarrier, 8 msec } in the preset resource block are 12, the distribution modes of the resource units of {12 subcarrier, 1 msec } in the preset resource block are 8, the distribution modes of the resource units of {3 subcarrier, 4 msec } in the preset resource block are 50, and the distribution modes of the resource units of {6 subcarrier, 2 msec } in the preset resource block are 49, that is, the distribution modes of the resource units in the preset resource block are 119 in total, a unique identifier can be given to each mode, so that the time-frequency resources corresponding to the distribution modes can be represented by the identifier.

In an optional scheme, the target signaling is used to instruct the target terminal to use the target time-frequency resource corresponding to the identifier as the allocated time-frequency resource. That is, the frequency domain starting point, the time domain starting point, the frequency domain length and the time domain length of the allocated time frequency resource are the same as those of the target time frequency resource.

In yet another alternative, the target signaling contains a number identifier K; the target signaling is used for indicating the target terminal to use the frequency domain starting point of the target time frequency resource corresponding to the identifier as the frequency domain starting point of the allocated time frequency resource, use the time domain starting point of the target time frequency resource as the time domain starting point of the allocated time frequency resource, use the frequency domain length of the target time frequency resource as the frequency domain length of the allocated time frequency resource, use the time domain lengths of K target time frequency resources as the time domain length of the allocated time frequency resource, and use K as a natural number.

Specifically, it is assumed that 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, then the time-domain starting point of the allocated time-frequency resource 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, the time-domain length of the allocated time-frequency resource is 2 × 2 milliseconds, and the frequency-domain length of the allocated time-frequency resource is 6 subcarriers. In addition, the number identifier 6 may also be a number predefined in the communication protocol between the reference terminal and the target terminal, so that the number identifier K does not need to be indicated in the target signaling.

For the possible implementation scheme, the frequency domain length of any one of the preset multiple time-frequency resources is an integer multiple of the frequency domain length of one of the preset multiple resource units, and 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, assuming that the resource units are {12 subcarriers, 1 millisecond } and {3 subcarriers, 4 milliseconds }, the frequency domain length of the time-frequency resource in the predetermined plurality of time-frequency resources is an integer multiple of 12 subcarriers or an integer multiple of 3 subcarriers, and the time domain length of the time-frequency resource in the predetermined 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 resource in the plurality of time-frequency resources may be: {12 subcarriers, 3 milliseconds }, {3 subcarriers, 8 milliseconds }, and so on.

Step S202: the target node receives the target signaling.

Step S203: and the target terminal analyzes 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 analyzes the target signaling, for example, decodes, demodulates, and obtains an identifier included in the target signaling, and if the target signaling further indicates a number identifier K, the target terminal also analyzes to obtain K; the specific meaning of the identifier and the quantity identifier (if present) is predefined in the communication protocol between the reference terminal and the target terminal, and when the target signaling indicates the time-frequency resource through the identifier, the target terminal may also analyze the time-frequency resource (i.e., the allocated time-frequency resource) indicated by the identifier correspondingly.

Step S204: and the target terminal transmits uplink data through the allocated time-frequency resource.

In the second method embodiment corresponding to fig. 2, an identifier is defined in advance for each time-frequency resource in a communication protocol between a reference terminal and a target terminal, the reference terminal sends a target signaling to the target terminal, the target terminal receives the target signaling, analyzes the identifier in the target signaling, finds the target time-frequency resource corresponding to the identifier from the communication protocol, and then determines a scheduled time-frequency resource based on the target time-frequency resource, and resource units of the time-frequency resource corresponding to each identifier in the communication protocol are not limited, so that the time-frequency resources of various resource units can be allocated to the target terminal in this way.

A third embodiment based on the flow diagram shown in fig. 2 is as follows:

Specifically, the target signaling includes a partition mode identifier and a region identifier, where the target signaling is used to instruct the target terminal to determine an allocated time-frequency resource based on a target time-frequency resource commonly specified by the partition mode identifier and the region identifier, and the allocated time-frequency resource is used for the target terminal to transmit uplink data; the preset resource block is divided into a plurality of regions in various dividing modes, each dividing mode corresponds to a dividing mode identifier, each region corresponds to a region identifier, and each divided region in the preset resource block is a time-frequency resource.

It should be noted that, time-frequency resources with the same specification may exist in each region into which the preset resource block is divided, and the time-frequency resources with the same specification specifically refer to time-frequency resources with the same frequency domain length and the same time domain length. Any one of the division modes has a unique division mode identifier, each of the division modes has a plurality of regions, each region corresponds to its own unique region identifier, and each region has a frequency domain starting point, a time domain starting point, a frequency domain length and a time domain length, that is, each region is a complete time-frequency resource.

In the embodiment of the present invention, two ways of dividing a preset resource block into a plurality of regions are listed through fig. 4 and 5. A division manner corresponding to the division manner shown in fig. 4 is identified as F1, and a division manner corresponding to the division manner shown in fig. 5 is identified as F2; each of fig. 4 and 5 includes region 1, region 2, region 3, region 4, region 5, region 6, region 7, and region 8, and the region identifications corresponding to region 1, region 2, region 3, region 4, region 5, region 6, region 7, and region 8 are Q1, Q2, Q3, Q4, Q5, Q6, Q7, and Q8 in this order; the target signaling may indicate, through the partition type identifier and the region identifier, the time-frequency resource in the preset resource block, for example, the partition type identifier and the region identifier included in the target signaling are (F1, Q5) indicating the time-frequency resource represented by the region 5 in the partition type shown in fig. 4.

In an optional scheme, the target signaling is used to instruct the target terminal to use a target time-frequency resource corresponding to the partition type identifier and the region identifier together as the allocated time-frequency resource. That is, the frequency domain starting point, the time domain starting point, the frequency domain length and the time domain length of the allocated time frequency resource are the same as those of the target time frequency resource.

In an optional scheme, the target signaling contains a quantity identifier T; the target signaling is used for indicating that the target terminal uses the frequency domain starting point of the target time frequency resource corresponding to the division mode identifier and the region identifier together as the frequency domain starting point of the allocated time frequency resource, uses the time domain starting point of the target time frequency resource as the time domain starting point of the allocated time frequency resource, uses the frequency domain length of the target time frequency resource as the frequency domain length of the allocated time frequency resource, uses the time domain lengths of T target time frequency resources as the time domain length of the allocated time frequency resource, and uses T as 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 region identifier is {6 subcarriers, 2 milliseconds }, and the number identifier T is equal to 2, then the time-domain starting point of the allocated time-frequency resource 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, the time-domain length of the allocated time-frequency resource is 2 × 2 milliseconds, and the frequency-domain length of the allocated time-frequency resource is 6 subcarriers. In addition, the quantity identifier may be a predefined 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 possible implementation scheme, the frequency domain length of any one time-frequency resource in the preset resource block is an integer multiple of the frequency domain length of one resource unit in the preset multiple resource units, and the time domain length of any one time-frequency resource is an integer multiple of the time domain length of the one resource unit.

For example, assuming that 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 predetermined resource block is an integer multiple of 12 subcarriers or an integer multiple of 3 subcarriers, and the time domain length of the time-frequency resource in the predetermined resource block is an integer multiple of 1 millisecond or an integer 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 }, and so on. Optionally, the plurality of resource units may also be {1 subcarrier, 8 msec }, {3 subcarriers, 4 msec }, {6 subcarriers, 2 msec } and {12 subcarriers, 1 msec }.

Step S202: the target node receives the target signaling.

Step S203: and the target terminal analyzes the target signaling and determines the allocated time frequency resources based on the target time frequency resources which are corresponding to the partition mode identification and the area identification in the target signaling.

Specifically, after receiving the target signaling, the target terminal analyzes the target signaling, for example, decodes, demodulates, and obtains a partition mode identifier and an area identifier included in the target signaling, and if the target signaling further indicates a quantity identifier T, the target terminal also analyzes to obtain T; the specific meanings of the partition mode identifier, the area identifier and the quantity identifier (if any) are predefined in the communication protocol between the reference terminal and the target terminal, and when the target signaling indicates the time-frequency resource through the partition mode identifier and the area identifier, the target terminal can also correspondingly analyze the time-frequency resource (namely, the allocated time-frequency resource) indicated by the partition mode identifier and the area identifier.

In the third method embodiment corresponding to fig. 2, a partition mode identifier and a region identifier are defined in advance for each time-frequency resource in a communication protocol between a reference terminal and a target terminal, a target signaling sent by the reference terminal to the target terminal includes the partition mode identifier and the region identifier, the terminal receives the target signaling, analyzes the partition mode identifier and the region identifier included in the target signaling, determines a target time-frequency resource corresponding to the partition mode identifier and the region identifier together according to the communication protocol, and determines a scheduled time-frequency resource according to the target time-frequency resource, and resource units of the time-frequency resource corresponding to each partition mode identifier and the region identifier together in the communication protocol are not limited, so that the time-frequency resources of various resource units can be allocated to the target terminal in this way.
