Technical Field

The present disclosure relates to the field of communications technologies, and in particular, to a data transmission method, a network device, a terminal, a storage medium, and an electronic device.

Background

A technical solution of Uplink and downlink decoupling is proposed in the 5G (the 5th Generation mobile communication technology, fifth Generation mobile communication) system, where the Uplink and downlink decoupling is characterized by having two Uplink/carriers and one downlink/carrier for one cell, where the two Uplink/carriers include a supplemental Uplink/carrier (SUL) and an Uplink/carrier (Uplink, UL).

Each cell in the current 5G standard only supports at most one supplementary uplink/carrier, but currently, global operators usually have multiple frequency bands, and considering the limited uplink bandwidth of the low frequency band, the operators expect that one cell uses more than one supplementary uplink/carrier. However, the uplink capacity in the network is limited because the uplink/carrier id in the related art can only indicate one uplink/carrier and one supplementary uplink/carrier, and does not support the technical solution that the same cell uses more than one supplementary uplink/carrier.

Detailed Description

The following detailed description of specific embodiments of the present disclosure is provided in connection with the accompanying drawings. It should be understood that the detailed description and specific examples, while indicating the present disclosure, are given by way of illustration and explanation only, not limitation.

In the description that follows, the terms "first," "second," and the like are used for descriptive purposes only and are not intended to indicate or imply relative importance nor order to be construed.

First, an application scenario of the present disclosure will be explained. The method can be applied to a 5G scene, the 5G system needs to support ultrahigh speed and ultra-large bandwidth, and because low-frequency resources are very limited, the 5G system mainly works in a high-frequency band at present, for example, a working frequency band above 3500 MHz. This is accompanied by the problem of 5G coverage, especially the uplink coverage stub is very significant due to the limited transmit power of the terminal. In order to make up for the Uplink coverage defect, a technical scheme of Uplink and downlink decoupling is proposed, wherein the Uplink and downlink decoupling is characterized in that two Uplink/carriers and one downlink/carrier are provided for one cell, wherein the two Uplink/carriers include a Supplementary Uplink/carrier (SUL) and one Uplink/carrier (Uplink, UL). The terminal side only works on one uplink/carrier at a time for cost.

In the related art, the network device may select a target uplink/carrier for the terminal from the uplink/carrier and the supplementary uplink/carrier according to the terminal capability reported by the terminal, and transmits PDCCH control signaling including a first uplink/carrier identity (1 bit) to the terminal, which, upon receiving the PDCCH control signaling, the target uplink/carrier may be determined based on the first uplink/carrier identification in the PDCCH control signaling and uplink data may be transmitted on the target uplink/carrier, e.g., when the first uplink/carrier id is 0, it indicates that the target uplink/carrier is an uplink/carrier, when the first uplink/carrier id is 1, it indicates that the target uplink/carrier is a supplemental uplink/carrier.

At present, a large number of frequencies are allocated to 5G globally, operators usually have multiple 5G frequency bands, for example, chinese telecommunications and chinese communications have 1800MHz and 2100MHz frequency bands, and chinese mobile has 1800MHz and 2600MHz frequency bands, and considering that a low frequency band uplink bandwidth is limited, the operators expect to configure more than one supplementary uplink/carrier, for example, the 1800MHz and 2100MHz frequency bands are used as supplementary uplink/carriers of 3500MHz frequency bands.

However, since the first uplink/carrier id in the related art can only indicate one uplink/carrier and one supplementary uplink/carrier and does not support the technical solution that the same cell uses more than one supplementary uplink/carrier, the uplink capacity in the network is limited, and a phenomenon of supplementary uplink/carrier congestion may occur.

In order to solve the above problems, the present disclosure provides a method, a network device, a terminal, a storage medium, and an electronic device for data transmission, where, for a case where a cell includes an uplink/carrier and at least two supplementary uplinks/carriers, a target uplink/carrier for transmitting uplink data is determined from the uplink/carrier and the at least two supplementary uplinks/carriers by extending a second uplink/carrier identifier and combining an original first uplink/carrier identifier, so that multiple scenarios of supplementary uplinks/carriers can be supported, a transmission bandwidth of uplink data is increased, a system capacity for uplink data transmission is increased, and requirements of different capabilities or different protocol versions of terminals in the network for simultaneous operation are met.

The following detailed description of specific embodiments of the present disclosure is provided in connection with the accompanying drawings.

Fig. 1 is a method for data transmission provided in an embodiment of the present disclosure, and as shown in fig. 1, an execution subject of the method may be a terminal, and the method includes:

s101, receive a PDCCH (Physical Downlink Control Channel) Control signaling sent by a network device.

Wherein, the PDCCH control signaling contains a first uplink/carrier identification and/or a second uplink/carrier identification.

In this step, the PDCCH control signaling may be one of two formats, DCI Format 0_0(Downlink control information Format 0_0) and DCI Format 0_1(Downlink control information Format 0_1), these two formats convey scheduling information for the PUSCH (Physical Uplink Shared Channel), including a first Uplink/carrier identification, and/or, a second Uplink/carrier identification, the first uplink/carrier identification and/or the second uplink/carrier identification is used for indicating a target uplink/carrier selected by the network equipment for the terminal, the target uplink/carrier is a link/carrier allocated by the network device for the terminal to transmit uplink data.

In this step, optionally, broadcast information sent by the network device may also be received, and uplink/carrier and/or uplink/carrier related information is acquired in the broadcast information, where the related information includes at least one of the following: the location of the center frequency point of the uplink/carrier; bandwidth of the uplink/carrier; the location of the center frequency point of the supplemental uplink/carrier; supplementing the bandwidth of the uplink/carrier.

S102, determining a target uplink/carrier from preset uplink/carriers according to a first uplink/carrier identifier and/or a second uplink/carrier identifier in the PDCCH control signaling.

Wherein the default uplink/carrier may include an uplink/carrier, and at least two supplemental uplink/carriers.

In this way, by extending one second uplink/carrier identifier, a scenario of performing uplink data transmission according to multiple supplementary uplinks/carriers can be supported, and compared with a case where the first uplink/carrier identifier can only indicate one uplink/carrier and one supplementary uplink/carrier in the related art, the present embodiment can support more supplementary uplinks/carriers, thereby increasing a bandwidth available for uplink data transmission and improving a capacity of uplink data transmission.

In this step, the target uplink/carrier may be determined by:

under the condition that the terminal supports reading the second uplink/carrier identifier, determining the target uplink/carrier from preset uplink/carriers according to the first uplink/carrier identifier and the second uplink/carrier identifier; or, according to the second uplink/carrier identifier, determining the target uplink/carrier from preset uplink/carriers;

and determining the target uplink/carrier according to the first uplink/carrier identification under the condition that the terminal does not support reading the second uplink/carrier identification.

In a possible implementation manner, it may be determined whether the terminal supports reading the second uplink/carrier identifier by obtaining a protocol version of the terminal, for example, if the protocol version number of the terminal is Release15 or Release16, it is determined that the terminal does not support reading the second uplink/carrier identifier; and if the protocol version number of the terminal is Release17 or more, determining that the terminal supports reading the second uplink/carrier identifier. It should be noted that Release is protocol version information of the mobile communication evolution that is defined by the 3GPP (3rd generation Partnership Project) organization, wherein Release15 is the first complete 5G protocol version, and Release16 and Release17 are subsequent evolution versions of 5G.

In another possible implementation manner, it may be determined whether the terminal supports reading the second uplink/carrier identifier by obtaining a specific indication field in a terminal FGI (functional group indication), for example: if the specific indication field of the terminal is 1, determining that the terminal supports reading the second uplink/carrier identifier; and if the specific indication field of the terminal is 0 or the indication field does not exist, determining that the terminal does not support reading the second uplink/carrier identification.

Another optional implementation manner for the network device to determine whether the terminal supports reading the second uplink/carrier identifier is as follows: the terminal capability information acquired by the network equipment comprises uplink/carrier and/or supplementary uplink/carrier capability information supported by the terminal. For example, the capability information reported by the terminal includes that the terminal supports the operation in the uplink/carrier n78 frequency band, and the terminal supports the operation in the two frequency bands of the supplemental uplink/carrier n3 and n 8.

Therefore, the requirement that the terminals with different capabilities or different protocol versions work simultaneously in the network can be met by judging whether the terminal supports reading the second uplink/carrier identifier and adopting different uplinks/carriers or supplementary uplinks/carriers to send uplink data.

And S103, sending uplink data to the network equipment on the target uplink/carrier.

In this step, the PDCCH control signaling may further include uplink resource scheduling information, where the uplink resource scheduling information includes time-frequency resource information allocated by the network device to the terminal uplink/carrier, and the time-frequency resource information is used to instruct the terminal to transmit uplink data on the corresponding time-frequency resource, and the terminal transmits the uplink data on the time-frequency resource of the target uplink/carrier.

By adopting the method, a scene of uplink data transmission according to a plurality of supplementary uplinks/carriers can be supported by expanding one second uplink/carrier identifier, compared with the situation that the first uplink/carrier identifier only indicates one uplink/carrier and one supplementary uplink/carrier in the related art, the embodiment can support more supplementary uplinks/carriers and normally send uplink data based on the selected supplementary uplink/carrier, thereby increasing the bandwidth available for uplink data transmission, reducing the congestion probability of the uplink/carrier, and the signaling design can be compatible with the requirement that terminals with different capabilities or different protocol versions in the network work simultaneously.

Fig. 2 is a second data transmission method provided in the embodiment of the present disclosure, and as shown in fig. 2, an execution subject of the method may be a network device, and the method includes:

s201, generating a PDCCH control signaling.

The PDCCH Control signaling may include a first uplink/carrier identifier and/or a second uplink/carrier identifier, where the PDCCH Control signaling may be one of DCI Format0_ 0(Downlink Control Information Format0_ 0) and DCI Format0_ 1(Downlink Control Information Format0_1, Downlink Control Information Format0_ 1), and the two formats transmit scheduling Information for a PUSCH (physical uplink Shared Channel).

In this step, a target uplink/carrier may be obtained, where the target uplink/carrier is a link/carrier that is allocated by the network device for the terminal and is used for sending uplink data; configuring a first uplink/carrier identity and/or a second uplink/carrier identity according to the target uplink/carrier to generate the PDCCH control signaling.

In a possible implementation manner, the network device may allocate a corresponding target uplink/carrier to the terminal according to a terminal capability reported by the terminal, and configure a first uplink/carrier identifier and/or a second uplink/carrier identifier according to the target uplink/carrier after determining the target uplink/carrier, where a specific manner in which the network device allocates the target uplink/carrier to the terminal may refer to a manner in which the network device allocates the uplink/carrier in the related art, and details thereof are not repeated here.

In addition, considering that the present application adds a second uplink/carrier identifier compared to the related art, and may not support reading the second uplink/carrier identifier for some older versions of terminals, so that terminals with different capabilities or different protocol versions in a compatible network can determine a target uplink/carrier from preset uplink/carriers, in another embodiment of the present disclosure, the network device may further determine whether the terminal supports reading the second uplink/carrier identifier, and configure the first uplink/carrier identifier and/or the second uplink/carrier identifier according to the determination result and the target uplink/carrier.

An optional implementation manner for the network device to determine whether the terminal supports reading the second uplink/carrier identifier is as follows: the terminal capability acquired by the network device may include a protocol version supported by the terminal, and the network device may determine, according to the protocol version, whether the terminal supports reading the second uplink/carrier identifier, so as to generate the first uplink/carrier identifier and/or the second uplink/carrier identifier according to the determination result and the target uplink/carrier. For example, if the protocol version number supported by the terminal is Release15 or Release16, it is determined that the terminal does not support reading the second uplink/carrier identity; and if the version number of the protocol supported by the terminal is Release17 or more, determining that the terminal supports reading the second uplink/carrier identifier.

Another optional implementation manner for the network device to determine whether the terminal supports reading the second uplink/carrier identifier is as follows: the terminal capability acquired by the network device may include FGI (functional group indicators) information of the terminal, where a specific indication field exists in the FGI information, and it is determined whether the terminal supports reading the second uplink/carrier identity through the specific indication field. For example: if the specific indication field of the terminal is 1, determining that the terminal supports reading the second uplink/carrier identifier; and if the specific indication field of the terminal is 0 or does not exist, determining that the terminal does not support reading the second uplink/carrier identification.

In a possible implementation manner, in a case that it is determined that the terminal supports reading the second uplink/carrier identifier, configuring the first uplink/carrier identifier and the second uplink/carrier identifier according to the target uplink/carrier, or configuring the second uplink/carrier identifier according to the target uplink/carrier; and under the condition that the terminal is determined not to support reading the second uplink/carrier identification, configuring the first uplink/carrier identification according to the target uplink/carrier.

By adopting the method, whether the terminal supports reading the second uplink/carrier identification is judged by acquiring the terminal capability, and different uplinks/carriers or supplementary uplinks/carriers are adopted to send uplink data, so that the requirement of simultaneous working of terminals with different capabilities or different protocol versions in a network can be met.

S202, sending the PDCCH control signaling to a terminal, so that the terminal determines a target uplink/carrier from preset uplink/carriers according to a first uplink/carrier identification and/or a second uplink/carrier identification in the PDCCH control signaling, and sends uplink data to the network equipment on the target uplink/carrier, wherein the preset uplink/carrier comprises the uplink/carrier and at least two supplementary uplinks/carriers.

In this embodiment, the PDCCH control signaling may further include uplink resource scheduling information, where the uplink resource scheduling information includes time-frequency resource information allocated by the network device to the terminal in an uplink/carrier, where the time-frequency resource information is used to instruct the terminal to transmit uplink data in a corresponding time-frequency resource, and after receiving the PDCCH control signaling, the terminal transmits the uplink data on a video resource of a target uplink/carrier.

In this step, optionally, broadcast information may also be sent, and the broadcast information includes related information of the uplink/carrier and/or supplements the uplink/carrier, where the related information includes at least one of the following: the location of the center frequency point of the uplink/carrier; bandwidth of the uplink/carrier; the location of the center frequency point of the supplemental uplink/carrier; supplementing the bandwidth of the uplink/carrier.

By adopting the method, the scenario of uplink data transmission according to a plurality of supplementary uplinks/carriers can be supported by expanding one second uplink/carrier identifier, and compared with the situation that the first uplink/carrier identifier can only indicate one uplink/carrier and one supplementary uplink/carrier in the related art, the embodiment can support more supplementary uplinks/carriers, thereby increasing the bandwidth available for uplink data transmission and improving the uplink capacity of the network.

Fig. 3 is a third method for data transmission according to an embodiment of the present disclosure, and as shown in fig. 3, the method includes:

s301, the network device configures a target uplink/carrier for the terminal according to the terminal capability reported by the terminal.

Wherein the target uplink/carrier is a link/carrier allocated by the network device for the terminal and used for transmitting uplink data.

It should be noted that, for a specific manner in which the network device configures the target uplink/carrier for the terminal, reference may be made to a manner in which the network device configures the uplink/carrier in the related art, and details are not described here.

S302, under the condition that the terminal supports reading the second uplink/carrier identifier, the network equipment configures the first uplink/carrier identifier and the second uplink/carrier identifier according to the target uplink/carrier to generate a PDCCH control instruction.

Wherein the PDCCH control order comprises the first uplink/carrier identity and the second uplink/carrier identity.

In this step, the first uplink/carrier identity and the second uplink/carrier identity may be configured to generate the PDCCH control instruction in any one of the following two ways:

in a first manner, according to the target uplink/carrier, a combination identifier is generated through a first preset link/carrier correspondence relationship, where the first preset link/carrier correspondence relationship includes a correspondence relationship between the preset uplink/carrier and the combination identifier, and the combination identifier includes the first uplink/carrier identifier and the second uplink/carrier identifier.

The preset uplink/carrier may include an uplink/carrier and at least two supplemental uplink/carriers, and the length of the second uplink/carrier identifier may be set to 1 bit, so that a plurality of supplemental uplink/carriers may be supported through a smaller signaling overhead, thereby reducing the PDCCH signaling overhead and increasing the network capacity.

For example, taking the preset uplink/carrier as an example including an uplink/carrier and three supplementary uplinks/carriers, which are respectively denoted as supplementary uplink/carrier a, supplementary uplink/carrier B, and supplementary uplink/carrier C, a possible first preset link/carrier correspondence relationship may be as shown in table 1 below:

Combined mark	Targeted uplink/carrier
		00	Uplink/carrier
01	Supplemental uplink/carrier a
		10	Supplemental uplink/carrier B
11	Supplemental uplink/carrier C

TABLE 1

As shown in table 1, when the target uplink/carrier is uplink/carrier, the corresponding combination identifier is 00, i.e. it means that the first uplink/carrier identifier is 0, the second uplink/carrier identifier is also 0, when the target uplink/carrier is supplemental uplink/carrier a, the corresponding combination identifier is 01, i.e. it means that the first uplink/carrier identifier is 0, the second uplink/carrier identifier is also 1, when the target uplink/carrier is supplemental uplink/carrier B, the corresponding combination identifier is 10, i.e. it means that the first uplink/carrier identifier is 1, the second uplink/carrier identifier is also 0, when the target uplink/carrier is supplemental uplink/carrier C, the corresponding combination identifier is 11, that is, it means that the first uplink/carrier identifier is 1, and the second uplink/carrier identifier is also 1, so that the network device may configure the first uplink/carrier identifier and the second uplink/carrier identifier according to the obtained target uplink/carrier, so as to generate the PDCCH control instruction. Thus, through the combined identifier formed by the first uplink/carrier identifier and the second uplink/carrier identifier, one uplink/carrier and three supplementary uplink/carriers can be indicated, thereby increasing the transmission bandwidth of uplink data and improving the system capacity of uplink data transmission. For a terminal that does not support reading the second uplink/carrier identity, the network device may configure the first uplink/carrier identity, and indicate uplink/carrier or supplemental uplink/carrier B with 1bit, e.g., 0 indicates uplink/carrier and 1 indicates supplemental uplink/carrier B.

It should be noted that the combination identifier in table 1 is illustrated in the form of "first uplink/carrier identifier + second uplink/carrier identifier", the present disclosure is not limited to this, and may also be in the form of "second uplink/carrier identifier + first uplink/carrier identifier", for example, when the combination identifier is 01, the second uplink/carrier identifier is 0, and the first uplink/carrier identifier is 1, and for example, when the combination identifier is 10, the second uplink/carrier identifier is 1, and the first uplink/carrier identifier is 0, and so on, and in addition, the first preset link/carrier correspondence relationship between the combination identifier and the target uplink/carrier is not limited to the correspondence relationship in table 1, and may also be other correspondence relationships, the first preset link/carrier correspondence may be preset according to an actual application scenario or user preference, for example, the first preset link/carrier correspondence may also be preset such that when the combination identifier is 11, the corresponding target uplink/carrier is an uplink/carrier, when the combination identifier is 10, the corresponding target uplink/carrier is a supplemental uplink/carrier a, when the combination identifier is 01, the corresponding target uplink/carrier is a supplemental uplink/carrier B, and when the combination identifier is 00, the corresponding target uplink/carrier is a supplemental uplink/carrier C. Of course, the above examples are illustrative and not limiting.

The second method comprises the following steps: configuring the first uplink/carrier identifier as a first parameter value in case that the target uplink/carrier is an uplink/carrier of the preset uplink/carriers; and configuring the first uplink/carrier identifier as a second parameter value under the condition that the target uplink/carrier is a supplementary uplink/carrier in the preset uplink/carrier, and configuring the second uplink/carrier identifier according to the target uplink/carrier.

It should be noted that, in this embodiment, when the target uplink/carrier is an uplink/carrier, only the first uplink/carrier identifier needs to be configured as the first parameter value, and no second uplink/carrier identifier needs to be configured, at this time, the length of the second uplink/carrier identifier is 0 bit, so as to save signaling overhead, and when the target uplink/carrier is a supplementary uplink/carrier in the preset uplink/carrier, the length of the second uplink/carrier identifier may be 1 bit, so that a plurality of supplementary uplinks/carriers can be supported through a smaller signaling overhead, and PDCCH signaling overhead is reduced, so as to improve network capacity.

For example, taking the example that the preset uplink/carrier includes an uplink/carrier and two supplementary uplink/carriers as an example, the first parameter value may be 0, the second parameter value may be 1, the two supplementary uplink/carriers are denoted as supplementary uplink/carrier a and supplementary uplink/carrier B, when the target uplink/carrier is uplink/carrier, the first uplink/carrier identifier is configured to be 0, when the target uplink/carrier is supplementary uplink/carrier a, the first uplink/carrier identifier is configured to be 1, and the second uplink/carrier identifier is configured to be 0, when the target uplink/carrier is supplementary uplink/carrier B, the first uplink/carrier identifier is configured to be 1, and configures the second uplink/carrier identity to be 1. The first parameter value is 0, and the second parameter value is 1, which are only examples and are not limited in this disclosure, and the first parameter value may also be 1, and the second parameter value may also be 0, which are not limited in this disclosure.

In addition, the first uplink/carrier identity is configured according to the target uplink/carrier in case it is determined that the terminal does not support reading the second uplink/carrier identity.

For example, when the target uplink/carrier is an uplink/carrier, the uplink/carrier may be configured to be 0, when the target uplink/carrier is any one of the supplementary uplink/carriers in the preset uplink/carrier, the uplink/carrier may be configured to be 1, of course, when the target uplink/carrier is an uplink/carrier, the uplink/carrier may also be configured to be 1, and when the target uplink/carrier is any one of the supplementary uplink/carriers in the preset uplink/carrier, the uplink/carrier may be configured to be 0, which is not limited by the present disclosure.

And S303, the network equipment sends the PDCCH control instruction to the terminal.

S304, under the condition that the terminal supports reading the second uplink/carrier identification, determining a target uplink/carrier from preset uplink/carriers according to the first uplink/carrier identification and the second uplink/carrier identification in the PDCCH control instruction sent by the network equipment.

In a possible implementation manner, it may be determined whether the terminal supports reading the second uplink/carrier identifier according to a protocol version of the terminal itself, for example, if a protocol version number of the terminal is Release15 or Release16, it is determined that the terminal does not support reading the second uplink/carrier identifier; and if the protocol version number of the terminal is Release17 or more, determining that the terminal supports reading the second uplink/carrier identifier.

Based on the two ways of configuring the first uplink/carrier identifier and the second uplink/carrier identifier by the network device in step S302, in this step, the terminal may determine the target uplink/carrier from the preset uplink/carriers in the corresponding two ways.

For the first mode in step S302, in a possible implementation manner, the terminal may determine a target uplink/carrier from preset uplinks/carriers through a first preset link/carrier correspondence according to the combined identifier when determining that reading of the second uplink/carrier identifier is supported, and determine the target uplink/carrier according to the first uplink/carrier identifier when the terminal does not support reading of the second uplink/carrier identifier.

Wherein the length of the second uplink/carrier identification may be 1 bit.

For example, the first predetermined link/carrier mapping relationship shown in table 1 is taken as an example, and is described with reference to the following table 2:

TABLE 2

As shown in table 2, for a terminal supporting Release15 or Release16 protocol versions (i.e., the terminal does not support reading the second uplink/carrier id), when the first uplink/carrier id is 0, the corresponding target uplink/carrier is uplink/carrier, and when the uplink/carrier id is 1, the corresponding target uplink/carrier is supplemental uplink/carrier B.

For a terminal supporting Release17 and above protocol versions (i.e., the terminal supports reading the second uplink/carrier id), when the first uplink/carrier id is 0 and the second uplink/carrier id is 0 (i.e., the combination id is 00), the corresponding target uplink/carrier is uplink/carrier, when the first uplink/carrier id is 0 and the second uplink/carrier id is 1 (i.e., the combination id is 01), the corresponding target uplink/carrier is supplemental uplink/carrier a, when the first uplink/carrier id is 1 and the second uplink/carrier id is 0 (i.e., the combination id is 10), the corresponding target uplink/carrier is supplemental uplink/carrier B, when the first uplink/carrier id is 1 and the second uplink/carrier id is 0 (i.e., the combination id is 10), when the second uplink/carrier id is 1 (i.e., the combination id is 11), the corresponding target uplink/carrier is the supplemental uplink/carrier C.

The correspondence relationship shown in table 2 is merely an example based on table 1, and the present disclosure is not limited thereto.

For the second mode in step S302, in another possible implementation manner, when the terminal does not support reading the second uplink/carrier identifier, and when the first uplink/carrier identifier is the first parameter value, the terminal takes the uplink/carrier as the target uplink/carrier; in case the first uplink/carrier identification is a second parameter value, the target uplink/carrier is determined from the supplementary uplink/carrier according to the second uplink/carrier identification. And the terminal determines the target uplink/carrier according to the first uplink/carrier identification under the condition that the terminal does not support reading the second uplink/carrier identification.

That is, in case of supporting reading of the second uplink/carrier identity, the terminal first determines whether the first uplink/carrier identity is a first parameter value, determines that the target uplink/carrier is an uplink/carrier in case of determining that the first uplink/carrier identity is the first parameter value, and secondly determines a parameter value of the second uplink/carrier identity in case of determining that the first uplink/carrier identity is a second parameter value, and determines the target uplink/carrier from the supplementary uplink/carriers according to the parameter value of the second uplink/carrier identity.

Wherein the length of the second uplink/carrier identification may be 1 bit.

Still taking the first parameter value as 0 and the second parameter value as 1 as an example, and taking table 3 as an example, as shown in table 3:

TABLE 3

As shown in table 3, for a terminal supporting Release15 or Release16 service protocols (i.e., the terminal does not support reading the second uplink/carrier id), when the first uplink/carrier id is 0, the corresponding target uplink/carrier is uplink/carrier, and when the uplink/carrier id is 1, the corresponding target uplink/carrier is supplemental uplink/carrier a.

For a terminal supporting Release17 and above service protocols (i.e. the terminal supports reading the second uplink/carrier id), when the first uplink/carrier id is 0, the corresponding target uplink/carrier is an uplink/carrier, when the first uplink/carrier id is 1 and the second uplink/carrier id is 0, the corresponding target uplink/carrier is a supplemental uplink/carrier a, and when the first uplink/carrier id is 1 and the second uplink/carrier id is 1, the corresponding target uplink/carrier is a supplemental uplink/carrier B.

S305, the terminal sends uplink data to the network device on the target uplink/carrier.

In this step, the PDCCH control instruction may further include uplink resource scheduling information, where the uplink resource scheduling information includes time-frequency resource information allocated by the network device to the terminal uplink/carrier, and the time-frequency resource information is used to instruct the terminal to transmit uplink data in the corresponding time-frequency resource, and after receiving the PDCCH control signaling, the terminal transmits the uplink data in the time-frequency resource of the target uplink/carrier.

By adopting the method, the scenario of uplink data transmission according to a plurality of supplementary uplinks/carriers can be supported by expanding one second uplink/carrier identifier, and compared with the situation that the first uplink/carrier identifier can only indicate one uplink/carrier and one supplementary uplink/carrier in the related art, the embodiment can support more supplementary uplinks/carriers, thereby increasing the bandwidth available for uplink data transmission and improving the uplink capacity of the network. Meanwhile, the length of the second uplink/carrier identifier is set to be 1 bit or 0 bit, and at least two supplementary uplink/carriers are supported by using smaller signaling overhead, so that the influence on the PDCCH capacity can be reduced, and the downlink capacity of the network is reduced or avoided from being damaged.

Fig. 4 is a fourth method for sending data according to an embodiment of the present disclosure, and as shown in fig. 4, the method includes:

s401, the network equipment configures a target uplink/carrier for the terminal according to the terminal capability reported by the terminal.

S402, under the condition that the terminal supports reading the second uplink/carrier identification, the network equipment configures the second uplink/carrier identification according to the target uplink/carrier to generate a PDCCH control instruction.

In this step, the terminal capability may include a protocol version of the terminal, and the network device may determine whether the terminal supports reading the second uplink/carrier identifier according to the protocol version.

For example, if the protocol version number supported by the terminal is Release15 or Release16, it is determined that the terminal does not support reading the second uplink/carrier identity; and if the version number of the protocol supported by the terminal is Release17 or more, determining that the terminal supports reading the second uplink/carrier identifier.

In a possible implementation manner, the length of the second uplink/carrier identifier is 2 bits, and the network device may determine, according to the target uplink/carrier, values on two bits of the second uplink/carrier identifier through a second preset link/carrier correspondence relationship, where the second preset link/carrier correspondence relationship includes a correspondence relationship between the preset uplink/carrier and the values on two bits of the second uplink/carrier identifier.

It should be noted that, in the case that it is determined that the terminal does not support reading the second uplink/carrier identity, the first uplink/carrier identity is configured according to the target uplink/carrier.

For example, the value of the second uplink/carrier id on two bits may be 0 or 1, taking the example that the predetermined uplink/carrier includes an uplink/carrier and three supplemental uplink/carriers (denoted as supplemental uplink/carrier a, supplemental uplink/carrier B, and supplemental uplink/carrier C, respectively) as an example, one possible second predetermined link/carrier correspondence relationship is shown in table 4 below:

second uplink/carrier identification	Targeted uplink/carrier
		00	Uplink/carrier
01	Supplemental uplink/carrier a
		10	Supplemental uplink/carrier B
11	Supplemental uplink/carrier C

TABLE 4

As shown in table 4, when the target uplink/carrier is uplink/carrier, the second uplink/carrier id may be configured to be 00, when the target uplink/carrier is supplemental uplink/carrier a, the second uplink/carrier id may be configured to be 01, when the target uplink/carrier is supplemental uplink/carrier B, the second uplink/carrier id may be configured to be 10, and when the target uplink/carrier is supplemental uplink/carrier C, the second uplink/carrier id may be configured to be 11.

S403, the network equipment sends the PDCCH control instruction to the terminal.

S404, under the condition that the terminal supports reading the second uplink/carrier identification, the terminal determines a target uplink/carrier from preset uplink/carriers according to the second uplink/carrier identification in the PDCCH control instruction sent by the network equipment.

Here, the terminal may determine whether reading of the second uplink/carrier identifier is supported according to a protocol version supported by the terminal, for example, if the protocol version number supported by the terminal is Release15 or Release16, it is determined that the terminal does not support reading of the second uplink/carrier identifier; and if the version number of the protocol supported by the terminal is Release17 or more, determining that the terminal supports reading the second uplink/carrier identifier.

In this step, the terminal may obtain values at two bits of the second uplink/carrier identifier, and determine a target uplink/carrier from preset uplink/carriers according to the values at the two bits through a second preset link/carrier correspondence relationship, where the second preset link/carrier correspondence relationship includes a preset correspondence relationship between the values at the two bits of the second uplink/carrier identifier and the preset uplink/carrier.

For example, the second predetermined link/carrier correspondence relationship shown in table 4 is still taken as an example, and is described with reference to the following table 5:

TABLE 5

As shown in table 5, for a terminal supporting Release15 or Release16 (i.e., the terminal does not support reading the second uplink/carrier id), when the first uplink/carrier id is 0, the corresponding target uplink/carrier is an uplink/carrier, and when the first uplink/carrier id is 1, the corresponding target uplink/carrier is any one of three supplemental uplink/carriers; for terminals supporting Release17 and above (i.e., terminals supporting reading the second uplink/carrier id), when the second uplink/carrier id is 00, the corresponding target uplink/carrier is uplink/carrier, and when the second uplink/carrier id is 01, the corresponding target uplink/carrier is supplemental uplink/carrier a; when the second uplink/carrier identifier is 10, the corresponding target uplink/carrier is a supplemental uplink/carrier B; when the second uplink/carrier id is 11, the corresponding target uplink/carrier is the supplemental uplink/carrier C. It should be noted that the correspondence relationships in table 4 and table 5 are merely examples, and the present disclosure does not limit the correspondence relationships.

S405, the terminal sends uplink data to the network device on the target uplink/carrier.

In this step, the PDCCH control instruction may further include uplink resource scheduling information, where the uplink resource scheduling information includes time-frequency resource information allocated by the network device to the terminal uplink/carrier, and the time-frequency resource information is used to instruct the terminal to transmit uplink data in the corresponding time-frequency resource, and after receiving the PDCCH control signaling, the terminal transmits the uplink data on the video resource of the target uplink/carrier.

By adopting the method, a scene of uplink data transmission according to a plurality of supplementary uplinks/carriers can be supported by expanding a second uplink/carrier identifier with the length of 2 bits, and compared with the situation that the first uplink/carrier identifier can only indicate one uplink/carrier and one supplementary uplink/carrier in the related art, the embodiment can support more supplementary uplinks/carriers, thereby increasing the bandwidth available for uplink data transmission and improving the uplink capacity of the network.

Through the device, a second uplink/carrier identifier is extended in the PDCCH control signaling, so that a scenario of uplink data transmission according to multiple supplementary uplinks/carriers can be supported, and compared with a case that the first uplink/carrier identifier can only indicate one uplink/carrier and one supplementary uplink/carrier in the related art, the present embodiment can support more supplementary uplinks/carriers, and normally transmit uplink data based on the selected supplementary uplink/carrier, thereby increasing a bandwidth available for uplink data transmission. Meanwhile, by adopting the method, the requirement that the terminals with different capabilities or different protocol versions work simultaneously in the network can be met by judging whether the terminal supports reading the second uplink/carrier identifier and adopting different uplinks/carriers or supplementary uplinks/carriers to send uplink data.

With regard to the apparatus in the above-described embodiment, the specific manner in which each module performs the operation has been described in detail in the embodiment related to the method, and will not be elaborated here.
