detailed description

Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. While the embodiments of the present invention have been shown in the drawings, the embodiments Rather, these embodiments are provided so that this disclosure will be more fully understood and the scope of the disclosure will be fully disclosed.

First embodiment

As shown in FIG. 1 , a resource reservation method for an uplink control channel according to an embodiment of the present invention is applied to a base station, and specifically includes the following steps 101 to 103.

Step 101: Schedule a downlink transport channel resource for transmitting downlink information for the terminal.

The downlink information includes downlink control information and downlink data information, and the corresponding downlink transport channel resources include: a downlink control channel resource and a downlink data channel resource. The base station schedules, for the terminal, downlink transmission channel resources for transmitting downlink information, and may send the downlink control information (such as the display control interface DCI information) to the terminal, or send the information to the terminal through a broadcast or other system message, so that the terminal learns the base station scheduling. Downlink transmission channel resources.

Step 102: Reserve corresponding uplink control channel resources for the terminal according to the downlink transmission channel resource.

And the corresponding uplink control channel resource is reserved for the terminal, so that the terminal can send uplink information by using the uplink control channel resource, according to a preset mapping relationship between the uplink control channel resource and the downlink transmission channel resource.

Step 103: Receive response information or other control information sent by the terminal by using the uplink control channel resource.

The base station receives the response information or other control information sent by the terminal by using the reserved uplink control channel resource. The response information or other control information includes at least: response feedback information corresponding to a downlink control channel in the downlink transport channel resource. Further, the response information or other control information further includes: response feedback information corresponding to the downlink data channel in the downlink transport channel resource. The response information is response feedback/non-response feedback (ACK/NACK), and the other control information is uplink control information other than the response information. Further, when the terminal does not receive the downlink information, the base station does not receive the ACK feedback information through the uplink control channel resource, and then continues to repeatedly send the downlink information to the terminal until the ACK feedback information is received. After receiving the downlink information, the terminal sends the ACK feedback through the corresponding uplink control channel resource, so that the base station stops sending the downlink information under the current transmission. The downlink information includes control information and data information, where the downlink transmission channel resource includes: a downlink control channel resource and a downlink data channel resource, and the response information or other control information received by the base station by using the uplink control channel resource includes: The response feedback information corresponding to the downlink control channel in the resource, and the response feedback information corresponding to the downlink data channel in the downlink transport channel resource. That is, the terminal separately performs ACK feedback on the control information and the data information. When the terminal receives the control information and does not receive the data information, the terminal only sends the ACK feedback of the control information through the corresponding uplink control channel. At this time, the base station passes the The uplink control channel resource receives the ACK feedback information corresponding to the downlink control channel, and then stops transmitting the control information and repeatedly transmits the data information until the ACK feedback information corresponding to the downlink data channel is received, so as to reduce the bit overhead of the control information. Save network transmission resources.

In the resource reservation method of the uplink control channel, the base station reserves the corresponding uplink control channel resource according to the downlink transmission channel resource scheduled by the terminal, so that the terminal feeds back the corresponding uplink control information through the uplink control channel resource, and the base station Determining whether the downlink information needs to be retransmitted according to the uplink control information, so as to meet the requirement of low latency and high reliability of the service, and further saving network transmission resources.

Second embodiment

The first embodiment of the present invention provides a brief introduction to the resource reservation method of the uplink control channel of the present invention. The following embodiments will be further described in conjunction with the accompanying drawings and specific application scenarios.

Specifically, the service transmission URLLC scenario as an example, to ensure the reliability URLLC service transmission, reliability of ^1-10-5, for a TB (Transport Block, transmission), the base station (GNB) may to a terminal (UE Transfer control information and data multiple times. The gNB stops transmitting until the UE feeds back the ACK. The control information load is small, the reliability requirement is high, and correspondingly, the data information load is large. Therefore, there may be a scenario in which the control information is correctly received, but the data information needs to be retransmitted multiple times. That is, in the URLLC service transmission scenario, the gNB repeatedly transmits control information and data information for one UE until the UE feeds back an ACK, and the gNB stops transmitting. Specifically, in the URLLC service transmission scenario, the control information and the data may be in a time diversity (TDM) manner, or multiple mini-slots may be scheduled for one downlink grant. The resource reservation method of the uplink control channel in the embodiment of the present disclosure is described in detail below in the control information and the data information transmission scenario.

Scenario 1: The acknowledgment information corresponding to the downlink control information is used as an example. As shown in FIG. 2, the resource reservation method of the uplink control channel in the embodiment of the present invention is applied to the base station, and specifically includes the following steps 201 to 203.

Step 201: Scheduling downlink transmission channel resources for transmitting downlink control information for the terminal.

The downlink transmission channel resource scheduled by the base station may be sent to the terminal by using downlink control information, a broadcast, or other system message.

Step 202: Reserve a corresponding first uplink control channel resource for the terminal according to the initial control channel unit CCE of the downlink grant information in the downlink transport channel resource.

According to different transmission scenarios and multiplexing modes, the manner of determining uplink control channel resources according to downlink transmission channel resources is different. Specifically, the control information and the data information may adopt a time division multiplexing (TDM) method and a frequency division multiplexing (FDM) method. The following will introduce different transmission scenarios and multiplexing methods.

When the control information and the data information are in the TDM or FDM mode, and the physical resource block (PRB) index of the URLLC service and the other service (such as eMBB) adopt a unified PRB index, that is, the entire frequency domain bandwidth, even if There are different numerical configurations (Numerology), and the PRBs are uniformly numbered from low frequency to high frequency. In this scenario, the base station reserves the uplink control channel resources in the following manner:

according to

Determining a first channel number corresponding to the starting CCE;

Reserving, for the terminal, a first uplink control channel resource whose channel number is the first channel number;

among them,

a channel number indicating the uplink control channel resource,

Indicates a starting CCE of downlink grant information in the downlink transport channel resource,

Indicates the offset of the uplink control channel resource of the service control channel configured by the upper layer.

When the control information and the data information are in TDM or FDM mode, but the PRB index of the URLLC service and the other services (such as eMBB) adopt separate PRB indexes, that is, the entire frequency domain bandwidth, different numerical configuration (Numerology), PRB They are numbered separately. In this scenario, the base station reserves the uplink control channel resources in the following manner:

according to

Determining a first channel number corresponding to the starting CCE;

Reserving, for the terminal, a first uplink control channel resource whose channel number is the first channel number;

among them,

a channel number indicating an uplink control channel resource,

Indicates the starting CCE of the downlink grant information in the downlink transport channel resource,

for

Function, the same under different numerical configurations

corresponding

different,

Indicates the offset of the uplink control channel resource of the service control channel configured by the upper layer.

In addition to the initial CCE indicating the downlink grant information in the downlink transport channel resource, it may also be the minimum value in the CCE of the downlink grant information in the downlink transport channel resource.

When the CCEs with different value configurations are numbered separately, the Numingology may have duplicate numbers. Therefore, when mapping the uplink transmission channel resources and the downlink transmission channel resources, you need to pass the

The mapping function distinguishes the same CCE number. For example, the CCE number used by Numerology1 is 1-100. Some of the resources are used for Numerology2, and its number is 1-80. At this point, there are two solutions to the potential conflict, the first one is different for different Numerology assignments.

Offset, the second is in the same

The offset is distinguished by a mapping function. For example, the function of Numerology2 is

among them

The sum of the CCE numbers for other Numerology.

Step 203: Receive, by using the first uplink control channel resource, response information or other control information sent by the terminal according to the downlink control information.

The base station receives the response information or other uplink control information sent by the terminal according to the received downlink control information by using the reserved first uplink control channel resource. The response information or other control information includes at least: response feedback information corresponding to a downlink control channel in the downlink transport channel resource. When the terminal does not receive the downlink control information, the base station fails to receive the ACK feedback information corresponding to the downlink control channel by using the first uplink control channel resource, and continues to repeatedly send the downlink control information to the terminal until the terminal correctly receives the downlink control. When the information is sent, the ACK feedback information is sent, and after receiving the ACK feedback information corresponding to the downlink control channel, the base station stops transmitting the downlink control information to the terminal. In order to avoid the problem that the base station keeps transmitting the downlink control information repeatedly due to the poor network state, the maximum number of transmissions of the primary transmission may be set in advance, so that the base station stops transmitting the downlink control information when repeatedly transmitting the downlink control information to the maximum number of transmissions. .

Specifically, the base station may notify the terminal through the DCI that the maximum number of times of downlink control information transmission in one transmission is four times. The maximum number of transmissions is different according to the transmission level. A specific bit may be added to the DCI information to indicate the transmission level. The value of the characteristic bit is different according to the indicated transmission level, and the corresponding maximum transmission number is different. For example, a maximum of four transmissions is indicated by 11 of 2 bits, and a maximum of 8 transmissions is indicated by 00 of 2 bits. In this way, in one transmission, the terminal successfully sends the ACK feedback information after receiving the downlink control information, and the base station does not repeatedly send the same downlink control information. When the terminal does not receive the downlink control information and reaches the maximum number of transmissions, the base station receives a NACK feedback information through the first uplink control channel, and the base station re-schedules the terminal after receiving the NACK feedback information. That is, the terminal does not receive the downlink control information, and after receiving the downlink transmission for 4 times, the base station receives the NACK feedback information sent by the terminal through the uplink control information, and re-schedules the terminal.

Scenario 2: Taking the response information of the downlink service data information as the example, as shown in FIG. 3, the resource reservation method of the uplink control channel in the embodiment of the present invention is applied to the base station, and specifically includes the following steps 301 to 303. .

Step 301: Schedule a downlink transmission channel resource for transmitting downlink service data information for the terminal.

The base station may send the scheduling information of the downlink transmission channel resource for transmitting the downlink service data information to the terminal together with the scheduling information of the downlink transmission channel resource for transmitting the downlink control information, so as to reduce the number of transmissions.

Step 302: Reserve a corresponding second uplink control channel resource for the terminal according to the starting physical resource block PRB that transmits the downlink service data information in the downlink transport channel resource.

Similar to step 202, the manner of determining the uplink control channel resources according to the downlink transmission channel resources is different according to different transmission scenarios and multiplexing modes. Specifically, the control information and the data information may be in a TDM manner and an FDM manner. The following will introduce different transmission scenarios and multiplexing methods.

When the control information and the data information are in the TDM or FDM mode, and the PRB index of the URLLC service and the other services (such as eMBB) use a unified PRB (Physical Resource Block) index, that is, the entire frequency domain bandwidth, even if there is a difference. Numerical configuration (Numerology), PRB is uniformly numbered from low frequency to high frequency. In this scenario, the base station reserves the uplink control channel resources in the following manner:

according to

Determining a second channel number corresponding to the starting PRB;

Reserving, for the terminal, a second uplink control channel resource whose channel number is the second channel number;

among them,

Indicates the channel number of the uplink control channel resource, and n _{PRB_start} indicates the initial PRB of the downlink service data information in the downlink transport channel resource.

Indicates the offset of the uplink control channel resource of the service data channel configured by the upper layer.

Further, if there are multiple different terminal multiplexing, the base station may jointly determine the start PRB of the downlink shared channel and the demodulation reference signal (DMRS) port number (ie, n _DMRS ),

Where F(n _DMRS ) is a mapping function of the DMRS port number, for example, F(n _DMRS )=n _DMRS -n _{DMRS starting port number value} , DMRS starting port number value may be 7,8, then the function will put DMRS The port number is mapped to 1, 2.

When the control information and the data information are in the TDM or FDM mode, the PRB index of the URLLC service and the other services (such as eMBB) use separate PRB (Physical Resource Block) indexes, that is, the entire frequency domain bandwidth is different. Numerical configuration (Numerology), PRB is numbered separately. In this scenario, the base station reserves the uplink control channel resources in the following manner:

according to

Determining a second channel number corresponding to the starting PRB;

Reserving, for the terminal, a second uplink control channel resource whose channel number is the second channel number;

among them,

Indicates uplink control channel resource channel number, n _{PRB_start} represents starting PRB downlink transmission channel resources to transmit downlink service data information, F (n _{PRB_start)} of n n _{PRB_start} the function, different values arranged _{PRB_start} is the same as the corresponding F ( n _{PRB_start} ) is different,

Indicates the offset of the uplink control channel resource of the service data channel configured by the upper layer.

The n _{PRB_start} may be a PRB corresponding to the lowest frequency index of the downlink transport channel resources, in addition to the initial PRB of the downlink service data information in the downlink transport channel resource.

When the PRBs of different values (Numerology) are numbered separately, different Numerology may have duplicate numbers. Therefore, when mapping uplink channel resources and downlink transport channel resources, F(n _{PRB_start} ) should be used to distinguish the same PRB index. Resource number. For example, Numerology1 uses a PRB number of 1-100, and some of the resources are used for Numerology2, which is numbered 1-80. At this point, there are two solutions to the potential conflict, the first one is different for different numerology assignments.

Offset, the second is in the same

The offset is distinguished by a mapping function. For example, the function of Numerology2 is

among them

The sum of the PRB numbers for other Numerology.

Step 303: The response information or other control information sent by the terminal according to the downlink service data information is received by the second uplink control channel resource.

The response information or other control information further includes: response feedback information corresponding to the downlink data channel in the downlink transport channel resource. When the terminal does not receive the downlink data information or the data decoding error, the base station fails to receive the ACK feedback information corresponding to the downlink data channel by using the second uplink control channel resource, and continues to repeatedly send the downlink service data information to the terminal until the terminal When receiving the downlink service data information, the ACK feedback information is sent, and after receiving the ACK feedback information corresponding to the downlink data channel, the base station stops transmitting the downlink service data information and the control channel information to the terminal. In the same way, in order to avoid the problem of repeated transmission of the base station caused by poor network status, the maximum number of transmissions of one transmission may be set in advance. When the terminal does not receive the downlink service data information and reaches the maximum number of transmissions, the base station passes the second uplink control. After receiving the NACK feedback information, the base station re-schedules the terminal after receiving the NACK feedback information. For the indication of the maximum number of transmissions, refer to the method in scenario one, and therefore no further details are provided herein.

In summary, the base station reserves the first uplink control channel resource for transmitting the response information or other control information for the terminal, so that the UE can respond to both the control information and the data information, and when the UE receives the control information, the ACK is returned, and the gNB stops. Subsequent transmission of control information, only data information is sent. This saves control resource overhead. When the UE decodes the data and correctly feeds back the ACK, the gNB will stop the repeated transmission of the current transport block and start the next new transmission. Specifically, the terminal receives downlink control information in the mini slot n, and the delay is k0, that is, its HARQ is fed back in the n+k0 mini slot. The terminal receives data in the mini slot n, and the delay is k1, that is, its HARQ is fed back in the n+k1 mini slot.

In the resource reservation method of the uplink control channel, the base station reserves the corresponding uplink control channel resource according to the downlink transmission channel resource scheduled by the terminal, so that the terminal feeds back the corresponding uplink control information through the uplink control channel resource, and the base station Determining whether the downlink information needs to be retransmitted according to the uplink control information, so as to meet the requirement of low latency and high reliability of the service, and further saving network transmission resources.

Fifth embodiment

The foregoing first embodiment to the fourth embodiment describe the resource reservation method of the uplink control channel of the present disclosure from the base station side. The following embodiment will be used to determine the resource determination method of the uplink control channel on the terminal side corresponding to the drawing. Further introduction.

As shown in FIG. 7, the resource determining method of the uplink control channel in the embodiment of the present disclosure is applied to the terminal, and specifically includes the following steps 701 to 703.

Step 701: Detect a downlink transport channel resource scheduled by the base station for transmitting downlink information.

The downlink information includes: downlink control information and downlink data information, and the corresponding downlink transmission channel resources include: a downlink control channel resource and a downlink data channel resource. The terminal may acquire downlink transmission channel resources scheduled by the base station for the terminal by receiving downlink control information (such as DCI information) or by broadcasting or other system messages.

Step 702: Determine a corresponding uplink control channel resource according to the detected downlink transmission channel resource.

Here, the terminal can directly determine the corresponding uplink control channel resource after detecting the downlink transmission channel resource according to the mapping relationship between the preset uplink control channel resource and the downlink transmission channel resource.

Step 703: Send a response message or other control information to the base station by using the uplink control channel resource.

The response information or other control information includes at least: response feedback information corresponding to a downlink control channel in the downlink transport channel resource. The response information is response feedback/non-response feedback (ACK/NACK), and other control information is uplink control information other than the response information. When the terminal does not receive the downlink information, the terminal does not send the ACK feedback to the base station, and the base station continues to repeatedly send the downlink information until the terminal receives the downlink information, and then sends the ACK feedback through the corresponding uplink control channel resource, so that the base station stops transmitting the current transmission. Downstream information. The downlink information includes control information and data information, and the terminal separately performs ACK feedback on the control information and the data information respectively. When the terminal receives the control information but does not receive the data information, the terminal only sends the control information through the corresponding uplink control channel. The ACK feedback causes the base station to stop transmitting the control information and continue to repeatedly transmit the data information until the ACK feedback of the data information is received, so as to reduce the bit overhead of the control information and save network transmission resources.

In the resource determining method of the uplink control channel according to the embodiment of the present disclosure, the terminal determines the corresponding uplink transmission channel resource according to the scheduling information of the downlink transmission channel resource scheduled by the base station, and further receives the downlink information by using the uplink control channel resource when receiving the downlink information. The information or other control information causes the base station to stop transmitting the downlink information repeatedly, meets the requirements of low delay and high reliability of the service, and further saves network transmission resources.

Sixth embodiment

The fifth embodiment of the present disclosure provides a brief introduction to the method for determining the resource of the uplink control channel of the present disclosure. The following embodiments will be further described in conjunction with the accompanying drawings and specific application scenarios.

As an example, the URLLC service transmission scenario is used to determine the transmission of the response information transmission resource corresponding to the downlink control information. As shown in FIG. 8 , the method for determining the resource of the uplink control channel in the embodiment of the present disclosure is applied to the terminal, and specifically includes the following steps. 801 to 803.

Step 801: Detect a downlink transmission channel resource scheduled by the base station for transmitting downlink control information.

By detecting downlink control information, broadcast, or other system messages, the downlink transmission channel resources scheduled by the base station for transmitting downlink control information are obtained.

Step 802: Determine a corresponding first uplink control channel resource according to the initial control channel unit CCE of the downlink grant information in the detected downlink transport channel resource.

In different transmission scenarios and multiplexing modes, the manner of determining uplink control channel resources according to downlink transmission channel resources is different. Among them, the control information and the data information can adopt the TDM method and the FDM method. The following will introduce different transmission scenarios and multiplexing methods.

When the control information and the data information are in the TDM or FDM mode, and the PRB index of the URLLC service and the other services (such as eMBB) use a unified PRB (Physical Resource Block) index, that is, the entire frequency domain bandwidth, even if there is a difference. Numerical configuration (Numerology), PRB is uniformly numbered from low frequency to high frequency. In this scenario, the terminal determines the uplink control channel resources by:

according to

Determining a first channel number corresponding to the starting CCE;

Determining a channel resource whose channel number is the first channel number as a first uplink control channel resource for transmitting uplink control information;

among them,

a channel number indicating an uplink control channel resource,

Indicates the starting CCE that receives the downlink authorization information.

Indicates the offset of the uplink control channel resource of the service control channel configured by the upper layer.

among them,

In addition to the initial CCE indicating the downlink grant information in the downlink transport channel resource, it may also be the minimum value in the CCE of the downlink grant information in the downlink transport channel resource.

When the control information and the data information are in the TDM or FDM mode, but the PRB index of the URLLC service and the other services use separate PRB indexes, the base station reserves the uplink control channel resources in the following manner:

according to

Determining a first channel number corresponding to the starting CCE;

Determining a channel resource whose channel number is the first channel number as a first uplink control channel resource for transmitting uplink control information;

among them,

a channel number indicating an uplink control channel resource,

Indicates the starting CCE that receives the downlink authorization information.

for

Function, under different numerical configurations

Corresponding

different,

Indicates the offset of the uplink control channel resource of the service control channel configured by the upper layer.

When CCEs with different value configurations are numbered separately, there may be duplicate numbers in different numerical configurations (Numerology). Therefore, when mapping uplink channel resources and downlink transport channel resources, you need to pass

The mapping function distinguishes the same CCE number. For example, the CCE number used by Numerology1 is 1-100. Some of the resources are used for Numerology2, and its number is 1-80. At this point, there are two solutions to the potential conflict, the first one is different for different Numerology assignments.

Offset, the second is in the same

The offset is distinguished by a mapping function. For example, the function of Numerology2 is

among them

The sum of the CCE numbers for other Numerology.

Step 803: After detecting the downlink control information transmitted in the downlink transport channel resource, send the first response information or other control information to the base station by using the first uplink control channel resource.

The response information or other control information includes at least: response feedback information corresponding to a downlink control channel in the downlink transport channel resource. When the terminal does not receive the downlink control information, the ACK feedback is not sent to the base station. When the base station does not receive the ACK feedback, the terminal will continue to repeatedly send the downlink control information until the terminal receives the downlink control information, and sends an ACK feedback message. The base station stops transmitting downlink control information after receiving the ACK feedback information. In order to avoid the problem that the base station keeps transmitting the downlink control information repeatedly due to the poor network state, the maximum number of transmissions of the primary transmission may be set in advance, so that the terminal sends a downlink control information to the base station when the downlink control information is not received and the maximum number of transmissions is reached. The NACK feedback information causes the base station to stop transmitting the downlink control information and reschedule the terminal.

Further, when determining the transmission of the response information transmission resource corresponding to the downlink service data information, as shown in FIG. 9, the method for determining the resource of the uplink control channel in the embodiment of the present disclosure is applied to the terminal, and specifically includes the following steps 901 to 903.

Step 901: Detect a downlink transport channel resource scheduled by the base station for transmitting downlink service data information.

The terminal can learn the downlink control channel resources for transmitting the downlink control information and the downlink service data information by detecting the downlink control information, the broadcast information, or other system information, so as to reduce the number of detections and save power consumption of the terminal.

Step 902: Determine a corresponding second uplink control channel resource according to the starting physical resource block PRB of the downlink data information transmitted in the detected downlink transport channel resource.

Similar to step 802, in different transmission scenarios and multiplexing modes, the manner of determining uplink control channel resources according to downlink transmission channel resources is different. The following describes the different transmission scenarios and multiplexing methods.

When the control information and the data information are in the TDM or FDM mode, and the PRB index of the URLLC service and the other services use a unified PRB index, the base station reserves the uplink control channel resources in the following manner:

according to

Determining a second channel number corresponding to the starting PRB;

Determining, by the channel resource whose channel number is the second channel number, a second uplink control channel resource for transmitting uplink data information;

among them,

Indicates the channel number of the uplink control channel resource, and n _{PRB_start} indicates the initial PRB of the downlink service data information.

Indicates the offset of the uplink control channel resource of the service data channel configured by the upper layer.

The n _{PRB_start} may be a PRB corresponding to the lowest frequency index of the downlink transport channel resources, in addition to the initial PRB of the downlink service data information in the downlink transport channel resource.

When the control information and the data information are in the TDM or FDM mode, but the PRB index of the URLLC service and the other services use separate PRB indexes, the base station reserves the uplink control channel resources in the following manner:

according to

Determining a second channel number corresponding to the starting PRB;

Determining a channel resource whose channel number is the second channel number as a second uplink control channel for transmitting uplink data information;

among them,

Indicates the channel number of the uplink control channel resource. n _{PRB_start} indicates the start PRB of the downlink service data information, and F(n _{PRB_start} ) is a function of n _{PRB_start} . When the different _{PR values} are the same, the corresponding F(n _{PRB_start} ) is different. ,

Indicates the offset of the uplink control channel resource of the service data channel configured by the upper layer.

When the PRBs of different values (Numerology) are numbered separately, different Numerology may have duplicate numbers. Therefore, when mapping uplink channel resources and downlink transport channel resources, F(n _{PRB_start} ) should be used to distinguish the same PRB index. Resource number. At this point, there are two solutions to the potential conflict, the first one is different for different Numerology assignments.

Offset, the second is in the same

The offset is distinguished by a mapping function. For example, the function of Numerology2 is

among them

The sum of the PRB numbers for other Numerology.

Step 903: After detecting downlink service data information transmitted in the downlink transport channel resource, send second acknowledgement information or other control information to the base station by using the second uplink control channel resource.

The response information or other control information further includes: response feedback information corresponding to the downlink data channel in the downlink transport channel resource. When the terminal does not receive the downlink control information, the terminal continues to repeatedly send the downlink control information until the terminal receives the downlink service data information, and sends an ACK feedback message, and the base station stops transmitting the downlink control information after receiving the ACK feedback information. In the same way, in order to avoid the problem of repeated transmission of the base station caused by poor network status, the maximum number of transmissions of the transmission may be set in advance. When the terminal does not receive the downlink service data information and reaches the maximum number of transmissions, the NACK feedback information is sent. After receiving the NACK feedback information, the base station stops transmitting downlink service data information, and re-schedules the terminal.

In the resource determining method of the uplink control channel according to the embodiment of the present disclosure, the terminal determines the corresponding uplink transmission channel resource according to the scheduling information of the downlink transmission channel resource scheduled by the base station, and further receives the downlink information by using the uplink control channel resource when receiving the downlink information. The information or other control information causes the base station to stop transmitting the downlink information repeatedly, meets the requirements of low delay and high reliability of the service, and further saves network transmission resources.
