Description

Information transmission method, terminal and base station

Technical Field

The present invention relates to the field of communications technologies, and in particular, to an information transmission method, a terminal, and a base station.

Background

In 5G NR, there may be multiple different traffic transmissions simultaneously for one terminal. For a high-reliability Ultra-Low Latency communication (URLLC) service, considering the characteristic of Low Latency, transmission of Hybrid Automatic Repeat Request ACK (HARQ-ACK) information is supported in one slot based on a sub-slot. The Uplink Control Information (UCI) of enhanced Mobile Broadband (eMBB) service is transmitted on a slot basis. Different services have different priorities, and a Physical Uplink Control Channel (PUCCH) carrying HARQ-ACK information of a higher priority service (e.g., URLLC service) may overlap with a PUCCH carrying HARQ-ACK information of a lower priority service (e.g., eMBB service) in a time domain. Currently, there is no specific transmission scheme for overlapping PUCCHs carrying different HARQ-ACK information in the time domain.

Specifically, an embodiment of the present invention provides an information transmission method, which solves the problem in the prior art that no specific transmission scheme exists when PUCCH resources carrying different HARQ-ACK information overlap in a time domain.

First embodiment

As shown in fig. 1, an embodiment of the present invention provides an information transmission method, which is applied to a terminal and specifically includes the following steps:

step 11: under the condition that a first Physical Uplink Control Channel (PUCCH) resource bearing a first hybrid automatic repeat request acknowledgement (HARQ-ACK) and a second PUCCH resource bearing a second HARQ-ACK are overlapped on a time domain, if a preset condition is met, determining a cyclic shift used for transmitting the first HARQ-ACK according to information bits of the second HARQ-ACK.

Wherein the preset conditions are as follows: the first HARQ-ACK is transmitted using a first PUCCH format and the second HARQ-ACK is transmitted using a second PUCCH format; or the first HARQ-ACK is transmitted by using a first PUCCH format, and the bit number of the second HARQ-ACK does not exceed a preset bit number.

Specifically, as an implementation: under the condition that a first Physical Uplink Control Channel (PUCCH) resource carrying a first hybrid automatic repeat request acknowledgement (HARQ-ACK) and a second PUCCH resource carrying a second HARQ-ACK are overlapped on a time domain, if the first HARQ-ACK uses a first PUCCH format for transmission and the second HARQ-ACK uses a second PUCCH format for transmission, determining a cyclic shift used for transmitting the first HARQ-ACK according to information bits of the second HARQ-ACK.

As another implementation: under the condition that a first Physical Uplink Control Channel (PUCCH) resource carrying a first hybrid automatic repeat request acknowledgement (HARQ-ACK) and a second PUCCH resource carrying a second HARQ-ACK are overlapped on a time domain, if the first HARQ-ACK is transmitted by using a first PUCCH format and the bit number of the second HARQ-ACK does not exceed a preset bit number, determining a cyclic shift used for transmitting the first HARQ-ACK according to the information bit of the second HARQ-ACK.

Step 12: transmitting the first HARQ-ACK using the cyclic shift on the first PUCCH resource.

Note that, when the first HARQ-ACK is transmitted on the first PUCCH resource by using the cyclic shift, transmission of a second HARQ-ACK is also performed at the same time (transmission of bit information of the second HARQ-ACK is performed by using a cyclic shift group corresponding to the cyclic shift used by the first HARQ-ACK).

Optionally, in the NR system, 5 PUCCH formats, that is, NR PUCCH formats (formats) 0,1, 2, 3, and 4, are defined, where PUCCH formats 0 and 1 may carry 1-2-bit Uplink Control Information (UCI) transmission, and PUCCH formats 2, 3, and 4 may carry UCI transmission with more than 2 bits. HARQ-ACK may use any one of the 5 PUCCH formats.

The base station may configure at least one PUCCH resource set for the terminal, where one PUCCH resource set may include multiple PUCCH resources, and different PUCCH resources may correspond to the same or different PUCCH formats.

If only one PUCCH resource set is configured, the set only contains PUCCH format 0,1 resources, and therefore, the method can be only used for 1-2 bit HARQ-ACK transmission.

If more than one PUCCH resource set is configured, different PUCCH resource sets can correspond to different UCI bit number ranges, the terminal can select one PUCCH resource set according to the number of bits of HARQ-ACK (if other UCIs are multiplexed with the HARQ-ACK, the total number of bits of all UCIs), and then determines one PUCCH resource in the determined PUCCH resource set according to a PUCCH resource indication field in a Physical Downlink Control Channel (PDCCH) corresponding to the HARQ-ACK, wherein the PUCCH resource is used for HARQ-ACK (or is multiplexed with other UCIs). Wherein, when the HARQ-ACK information is feedback information of a Physical Downlink control Channel (PDSCH), the PDCCH is a PDCCH for scheduling the PDSCH; or, when the HARQ-ACK information is feedback information of a PDCCH indicating release of downlink semi-persistent scheduling (SPS) resources, the PDCCH is the PDCCH itself for release of the downlink SPS resources.

For HARQ-ACK without corresponding PDCCH, i.e. carrying SPS HARQ-ACK (i.e. HARQ-ACK corresponding to SPS PDSCH), since one SPS HARQ-ACK is only 1 bit, PUCCH format 0 or 1 may be used for transmission on 1 PUCCH resource configured by higher layer signaling. A Scheduling Request (SR) may be transmitted on one PUCCH resource configured by higher layer signaling using PUCCH format 0 or 1. The periodic Channel State Information (CSI) may be configured to be transmitted on one PUCCH resource configured by higher layer signaling using PUCCH format 2 or 3 or 4.

In this way, when a first PUCCH resource carrying a first HARQ-ACK and a second PUCCH resource carrying a second HARQ-ACK overlap in a time domain, if the first HARQ-ACK and the second HARQ-ACK satisfy a preset condition, the first HARQ-ACK is transmitted on the first PUCCH resource using a cyclic shift used for transmitting the first HARQ-ACK, which is determined according to information bits of the second HARQ-ACK. Therefore, the first HARQ-ACK and the second HARQ-ACK can be transmitted on the same PUCCH resource simultaneously on the basis of ensuring that the transmission delay of the first HARQ-ACK is not influenced by using different cyclic shifts for transmission on the PDCCH resource bearing the first HARQ-ACK.

Second embodiment

As shown in fig. 2, a second embodiment of the present invention provides an information transmission method, which specifically includes the following steps:

step 21: under the condition that a first Physical Uplink Control Channel (PUCCH) resource bearing a first hybrid automatic repeat request acknowledgement (HARQ-ACK) and a second PUCCH resource bearing a second HARQ-ACK are overlapped on a time domain, if a preset condition is met, a target cyclic shift group is determined according to information bits of the second HARQ-ACK.

Specifically, as an implementation: under the condition that a first Physical Uplink Control Channel (PUCCH) resource carrying a first hybrid automatic repeat request acknowledgement (HARQ-ACK) and a second PUCCH resource carrying a second HARQ-ACK are overlapped on a time domain, if the first HARQ-ACK uses a first PUCCH format for transmission and the second HARQ-ACK uses a second PUCCH format for transmission, a target cyclic shift group is determined according to information bits of the second HARQ-ACK.

As another implementation: under the condition that a first Physical Uplink Control Channel (PUCCH) resource carrying a first hybrid automatic repeat request acknowledgement (HARQ-ACK) and a second PUCCH resource carrying a second HARQ-ACK are overlapped on a time domain, if the first HARQ-ACK is transmitted by using a first PUCCH format and the bit number of the second HARQ-ACK does not exceed a preset bit number, determining a target cyclic shift group according to the information bit of the second HARQ-ACK.

The above steps are specifically described below with reference to specific scenarios:

scene one: the bit number of the second HARQ-ACK is 1.

The step of determining a target cyclic shift group according to the information bits of the second HARQ-ACK may specifically include:

Specifically, when the bit number of the second HARQ-ACK is 1, the first cyclic shift group or the second cyclic shift group is selected to be used according to whether the information bit of the 1-bit second HARQ-ACK is ACK or NACK. Such as: when the information bit of the 1-bit second HARQ-ACK is ACK, the information bit corresponds to a first cyclic shift group; and when the information bit of the 1-bit second HARQ-ACK is NACK, the information bit corresponds to a second cyclic shift group, and the cyclic shifts in the first cyclic shift group and the second cyclic shift group are different.

Scene two: the bit number of the second HARQ-ACK is larger than 1.

combining the second HARQ-ACK to obtain a combined 1-bit second HARQ-ACK;

optionally, a logical and operation may be performed on the second HARQ-ACK greater than 1 bit, so as to obtain a combined 1-bit second HARQ-ACK.

Specifically, when the bit number of the second HARQ-ACK is greater than 1, combining the second HARQ-ACK with greater than 1 bit (for example, performing a logical and operation between the second HARQ-ACKs with greater than 1 bit), so as to obtain the second HARQ-ACK with 1 bit combined. And further selecting to use a first cyclic shift group or a second cyclic shift group according to the condition that the information bit of the 1-bit combined second HARQ-ACK is ACK or NACK.

Such as: the information bit of the second HARQ-ACK after the 1-bit combination corresponds to a first cyclic shift group when the information bit is ACK; and when the information bit of the 1-bit second HARQ-ACK is NACK, the information bit corresponds to a second cyclic shift group, and the cyclic shift in the first cyclic shift group is different from that in the second cyclic shift group.

Step 22: and determining the cyclic shift used for transmitting the first HARQ-ACK in the target cyclic shift group according to the information bits of the first HARQ-ACK.

Specifically, with reference to scenario one: the first cyclic shift group comprises cyclic shifts corresponding to different information bits of the first HARQ-ACK, wherein the cyclic shifts corresponding to the different information bits are different.

Such as: when the information bit of the 1-bit second HARQ-ACK is ACK, selecting and using the cyclic shift corresponding to the information bit of the first HARQ-ACK in the first cyclic shift group as the cyclic shift used for transmitting the first HARQ-ACK; and when the information bit of the 1-bit second HARQ-ACK is NACK, selecting and using the cyclic shift corresponding to the information bit of the first HARQ-ACK in the second cyclic shift group as the cyclic shift used for transmitting the first HARQ-ACK.

Specifically, in combination with the second scenario: and the second cyclic shift group comprises cyclic shifts corresponding to different information bits of the first HARQ-ACK, wherein the cyclic shifts corresponding to the different information bits are different.

Such as: when the information bit of the second HARQ-ACK after the 1-bit combination is ACK, selecting and using the cyclic shift corresponding to the information bit of the first HARQ-ACK in a first cyclic shift group as the cyclic shift used for transmitting the first HARQ-ACK; and when the information bit of the second HARQ-ACK after the 1-bit combination is NACK, selecting and using the cyclic shift corresponding to the information bit of the first HARQ-ACK in a second cyclic shift group as the cyclic shift used for transmitting the first HARQ-ACK.

Step 23: transmitting the first HARQ-ACK using the cyclic shift on the first PUCCH resource.

Note that, when the first HARQ-ACK is transmitted on the first PUCCH resource using the cyclic shift, transmission of a second HARQ-ACK also occurs at the same time.

In this embodiment, when a first PUCCH resource carrying a first HARQ-ACK and a second PUCCH resource carrying a second HARQ-ACK overlap in a time domain, if the first HARQ-ACK and the second HARQ-ACK satisfy the preset condition, the first HARQ-ACK is transmitted on the first PUCCH resource by using a cyclic shift used for transmitting the first HARQ-ACK, which is determined according to information bits of the second HARQ-ACK. Therefore, the first HARQ-ACK and the second HARQ-ACK can be transmitted on the same PUCCH resource simultaneously on the basis of ensuring that the transmission delay of the first HARQ-ACK is not influenced by using different cyclic shifts for transmission on the PDCCH resource bearing the first HARQ-ACK.

According to at least one embodiment of the foregoing, the selectable predetermined number of bits is: 1 or 2.

According to at least one embodiment of the foregoing, the selectable first PUCCH format is: PUCCH format 0.

According to at least one embodiment of the foregoing, the selectable second PUCCH format is: PUCCH format 0 or PUCCH format 1.

That is, as a preferred implementation manner, for the first PUCCH format, the following is used: a PUCCH format 0, the second PUCCH format being: under the condition that the bit number of PUCCH format 0 or PUCCH format 1 or second HARQ-ACK does not exceed 1 or 2, if a first PUCCH resource bearing first HARQ-ACK and a second PUCCH resource bearing second HARQ-ACK are overlapped on a time domain, the first HARQ-ACK is transmitted on the first PUCCH resource by using the cyclic shift determined according to the information bit of the second HARQ-ACK and used for transmitting the first HARQ-ACK, so that the first HARQ-ACK and the second HARQ-ACK are simultaneously transmitted on the same PUCCH resource on the basis of ensuring that the transmission delay of the first HARQ-ACK is not influenced by using different cyclic shifts for transmission on the PDCCH resource bearing the first HARQ-ACK.

According to at least one embodiment of the foregoing, optionally, the service type corresponding to the first HARQ-ACK is a first service type, the service type corresponding to the second HARQ-ACK is a second service type, and the priority of the first service type is higher than the priority of the second service type.

In the embodiment, for the case that the priority level of the service type corresponding to the first HARQ-ACK is higher than the priority level of the service type corresponding to the second HARQ-ACK, the transmission is performed by using different cyclic shifts on the resource corresponding to the HARQ-ACK with higher priority, so that the multiplexing transmission of the HARQ-ACKs with different service types is realized on the basis of ensuring that the transmission delay of the HARQ-ACK with higher priority is not affected.

According to at least one embodiment, the optional first HARQ-ACK corresponds to a high-reliability ultra-low latency communication URLLC service, and the second HARQ-ACK corresponds to an enhanced mobile broadband eMBB service. In the embodiment, for the situation that the first HARQ-ACK corresponds to the URLLC service and the second HARQ-ACK corresponds to the eMBB service, different cyclic shifts are used for transmission on the resource corresponding to the HARQ-ACK of the URLLC service, so that the multiplexing transmission of the HARQ-ACK corresponding to the URLLC service and the HARQ-ACK corresponding to the eMBB service is realized on the basis of ensuring that the transmission delay of the HARQ-ACK of the URLLC service is not affected.

According to at least one embodiment of the above, optionally the first HARQ-ACK corresponds to a first priority class, the second HARQ-ACK corresponds to a second priority class, and the first priority class is higher than the second priority class.

In the embodiment, for the case that the priority level corresponding to the first HARQ-ACK is higher than the priority level corresponding to the second HARQ-ACK, the multiplexing transmission of the HARQ-ACKs corresponding to different priority levels is realized by using different cyclic shifts for transmission on the resource corresponding to the HARQ-ACK of higher priority, so that the transmission delay of the HARQ-ACK of higher priority is not affected.

Therefore, the first HARQ-ACK and the second HARQ-ACK can be transmitted on the same PUCCH resource simultaneously on the basis of ensuring that the transmission delay of the first HARQ-ACK is not influenced by using different cyclic shifts for transmission on the PDCCH resource bearing the first HARQ-ACK.

Fifth embodiment

As shown in fig. 5, an embodiment of the present invention further provides an information transmission method, which is applied to a base station, and includes:

step 51: under the condition that a first Physical Uplink Control Channel (PUCCH) resource bearing a first hybrid automatic repeat request acknowledgement (HARQ-ACK) and a second PUCCH resource bearing a second HARQ-ACK are overlapped on a time domain, if a preset condition is met, receiving the first HARQ-ACK and the second HARQ-ACK on the first PUCCH resource according to a cyclic shift group corresponding to different information bits of the second HARQ-ACK;

Specifically, as an implementation: under the condition that a first Physical Uplink Control Channel (PUCCH) resource bearing a first hybrid automatic repeat request acknowledgement (HARQ-ACK) and a second PUCCH resource bearing a second HARQ-ACK are overlapped on a time domain, if the first HARQ-ACK uses a first PUCCH format for transmission and the second HARQ-ACK uses a second PUCCH format for transmission, the first HARQ-ACK and the second HARQ-ACK are received on the first PUCCH resource according to cyclic shift groups corresponding to different information bits of the second HARQ-ACK.

As another implementation: under the condition that a first Physical Uplink Control Channel (PUCCH) resource bearing a first hybrid automatic repeat request acknowledgement (HARQ-ACK) and a second PUCCH resource bearing a second HARQ-ACK are overlapped on a time domain, if the first HARQ-ACK is transmitted by using a first PUCCH format and the bit number of the second HARQ-ACK is not more than a preset bit number, receiving the first HARQ-ACK and the second HARQ-ACK on the first PUCCH resource according to a cyclic shift group corresponding to different information bits of the second HARQ-ACK.

In this embodiment, when a first PUCCH resource carrying a first HARQ-ACK and a second PUCCH resource carrying a second HARQ-ACK overlap in a time domain, if the first HARQ-ACK and the second HARQ-ACK satisfy a preset condition, the first HARQ-ACK and the second HARQ-ACK are received on the first PUCCH resource according to a cyclic shift group corresponding to different information bits of the second HARQ-ACK. Therefore, the first HARQ-ACK and the second HARQ-ACK can be transmitted on the same PUCCH resource simultaneously on the basis of ensuring that the transmission delay of the first HARQ-ACK is not influenced by using different cyclic shifts for transmission on the PDCCH resource bearing the first HARQ-ACK.

Optionally, because the base station side does not determine the information bits of the first HARQ-ACK and the second HARQ-ACK in advance, it is necessary to blind-check and receive the first HARQ-ACK in multiple cyclic shift groups; the step 51 may specifically include:

determining the information bit of the second HARQ-ACK as ACK under the condition that the information is received by using the cyclic shift in the first cyclic shift group, and determining the information bit of the first HARQ-ACK according to the cyclic shift of the received information in the first cyclic shift group;

determining the information bit of the second HARQ-ACK as NACK under the condition that information is received by using the cyclic shift in a second cyclic shift group, and determining the information bit of the first HARQ-ACK according to the cyclic shift of the received information in the second cyclic shift group;

In this embodiment, the base station side may determine the information bits of the first HARQ-ACK and the second HARQ-ACK by receiving the first HARQ-ACK in a blind detection in a plurality of cyclic shift groups.

According to at least one embodiment, the optional first HARQ-ACK corresponds to a high-reliability ultra-low latency communication URLLC service, and the second HARQ-ACK corresponds to an enhanced mobile broadband eMBB service.

In the embodiment, for the situation that the first HARQ-ACK corresponds to the URLLC service and the second HARQ-ACK corresponds to the eMBB service, different cyclic shifts are used for transmission on the resource corresponding to the HARQ-ACK of the URLLC service, so that the multiplexing transmission of the HARQ-ACK corresponding to the URLLC service and the HARQ-ACK corresponding to the eMBB service is realized on the basis of ensuring that the transmission delay of the HARQ-ACK of the URLLC service is not affected.

The following describes the information transmission method between the terminal side and the base station side with reference to a specific example:

one PUCCH bearing HARQ-ACK corresponding to URLLC service is overlapped with one PUCCH resource bearing HARQ-ACK corresponding to eMBL service, namely the first HARQ-ACK is the HARQ-ACK corresponding to URLLC service, and the second HARQ-ACK is the HARQ-ACK corresponding to eMBL service.

Wherein the first HARQ-ACK is transmitted using PUCCH format 0, i.e., using the first PUCCH format; the bit number of the second HARQ-ACK is 1, and the second HARQ-ACK is transmitted using one of PUCCH formats 0,1, i.e., using the second PUCCH format.

The following is specifically described for the bit number case of the first HARQ-ACK:

case 1: the number of bits of HARQ-ACK corresponding to URLLC, i.e. the first HARQ-ACK, is 1, e.g.: the following tables 1 and 2 are predefined, and a set of cyclic shifts used by the first HARQ-ACK when the bit information of the second HARQ-ACK is ACK and NACK is respectively given;

table 1: when the bit information of the second HARQ-ACK is ACK, the corresponding relation between the information bits of the 1-bit first HARQ-ACK and the cyclic shift is as follows:

information bit (or HARQ-ACK Value)	NACK (or 0)	ACK (or 1)
			Cyclic shift (Sequence cyclic shift)	m_CS＝3	m_CS＝9

Table 2: when the bit information of the second HARQ-ACK is NACK, the corresponding relation between the 1-bit first HARQ-ACK and the cyclic shift is as follows:

information bit (or HARQ-ACK Value)	NACK (or 0)	ACK (or 1)
			Cyclic shift (Sequence cyclic shift)	m_CS＝0	m_CS＝6

For the terminal side: and when the information bit of the HARQ-ACK corresponding to the eMBB service is ACK, determining to transmit the first HARQ-ACK by using the cyclic shift in the table 1.

Specifically, one of the cyclic shifts in table 1 is selected according to whether the 1-bit first HARQ-ACK information bit is ACK or NACK, and the selected cyclic shift is used to transmit the first HARQ-ACK on the PUCCH resource corresponding to the first HARQ-ACK (which should also include transmission of the second HARQ-ACK);

when the information bit of the HARQ-ACK corresponding to the eMBB service is NACK, it is determined that the first HARQ-ACK is transmitted using the cyclic shift in Table 2.

Specifically, one of the cyclic shifts in table 2 is selected according to whether the 1-bit first HARQ-ACK information bit is ACK or NACK, and the selected cyclic shift is used to transmit the first HARQ-ACK on the PUCCH resource corresponding to the first HARQ-ACK (which should also include transmission of the second HARQ-ACK).

Aiming at the base station side: in the same way, the PUCCH resource carrying the second HARQ-ACK and the PUCCH resource carrying the first HARQ-ACK are overlapped, but the base station does not determine which cyclic shift group the terminal uses because the information bit of the second HARQ-ACK is not determined in advance; and it cannot be determined which cyclic shift the first HARQ-ACK uses for transmission since the information bits of the first HARQ-ACK are not determined. In this way, the base station needs to blindly detect the first HARQ-ACK in two cyclic shift groups, that is, receive the sequence on the PUCCH resource corresponding to the first HARQ-ACK by using a total of 4 cyclic shifts in table 1 and table 2, and reversely deduce the information bits of the first HARQ-ACK and the second HARQ-ACK according to the corresponding relationship of table 1 and table 2 according to the cyclic shift corresponding to the correctly received sequence, for example: the base station determines, through blind detection, that the sequence is received at the second cyclic shift in table 2, and then may determine that the information bit of the first HARQ-ACK is ACK and the information bit of the second HARQ-ACK is NACK.

Case 2: the bit number of the HARQ-ACK corresponding to the URLLC service is 2, for example, the following tables 3 and 4 are predefined, and a set of cyclic shifts used by the first HARQ-ACK when the information bit of the second HARQ-ACK is ACK and NACK is given respectively;

table 3: when the information bit of the second HARQ-ACK is ACK, the corresponding relation between the information bit of the 2-bit first HARQ-ACK and the cyclic shift is as follows:

table 4: when the information bit of the second HARQ-ACK is NACK, the corresponding relation between the information bit of the 2-bit first HARQ-ACK and the cyclic shift is as follows:

specifically, the specific transmission modes at the terminal side and the base station side are the same as above, and the difference is that table 1 in the above method is replaced by table 3, and table 2 is replaced by table 4, which is not described herein again.

It should be noted that, according to at least one of the above embodiments, if the second HARQ-ACK is 2 bits (certainly, it may also be more than 2 bits), the 2-bit second HARQ-ACK may be combined first to obtain a combined 1-bit second HARQ-ACK, and the above method is repeated, which is not described herein again.

It should be further noted that, the relative positions of the PUCCH resources of the first HARQ-ACK and the second HARQ-ACK in the above embodiments of the present invention are only examples, and the starting position of the PUCCH resource carrying the second HARQ-ACK may be earlier than the starting position of the PUCCH resource carrying the first HARQ-ACK, or the starting position of the PUCCH resource carrying the second HARQ-ACK may be later than the starting position of the PUCCH resource carrying the first HARQ-ACK, or the starting position of the PUCCH resource carrying the second HARQ-ACK may be aligned with the starting position of the PUCCH resource carrying the first HARQ-ACK; of course, the end position of the PUCCH resource carrying the second HARQ-ACK may be earlier than the end position of the PUCCH resource carrying the first HARQ-ACK, or the end position of the PUCCH resource carrying the second HARQ-ACK may be later than the end position of the PUCCH resource carrying the first HARQ-ACK, or the end position of the PUCCH resource carrying the second HARQ-ACK may be aligned with the end position of the PUCCH resource carrying the first HARQ-ACK.

It should be further noted that, in the embodiment of the present invention, when the UCI is HARQ-ACK, the PUCCH carrying the HARQ-ACK is transmitted in one sub-slot in one slot, and the PUCCH carrying the second HARQ-ACK may be slot-based or sub-slot-based transmission. The sub-time slots are time units with fixed symbol number in one appointed or configured time slot; the order of the sub-slots in a slot, the position of each sub-slot and the number of symbols included in the sub-slot are predetermined or configured. While different subslots within a slot may contain the same or different number of symbols. That is, each sub-slot included in the same slot may include the same number of symbols, for example: each subslot in the same time slot comprises 7 or 2 symbols; of course, the number of symbols included in each sub-slot may also be different, for example: the first subslot includes 4 symbols and the second subslot includes 3 symbols, but the specific number of symbols may be determined by pre-engagement or configuration.

It should be further noted that, in the embodiment of the present invention, the HARQ-ACK includes SPS HARQ-ACK and/or dynamic (dynamic) HARQ-ACK.

The above embodiments describe the information transmission method of the present invention, and the following embodiments further describe the corresponding base station with reference to the accompanying drawings.
