Description

Information transmission method, device, equipment and computer readable storage medium

Technical Field

The present invention relates to the field of communications technologies, and in particular, to an information transmission method, apparatus, device, and computer readable storage medium.

Background

In 5g r15 NR (New Radio, new air interface), simultaneous transmission (time domain resource overlapping) of PUCCH (Physical Uplink Control Channel ) and PUSCH (Physical Uplink Shared Channel, physical uplink shared channel) is not supported from the standpoint of reducing PAPR (Peak to Average Power Ratio, peak-to-average power ratio) and CM (Connection Management ), nor are multiple PUCCHs with overlapping transmitted simultaneously on the same carrier.

When all or part of symbols of one PUCCH and one PUSCH overlap, a determination needs to be made as to whether or not a predefined time condition (timing) is satisfied for a first symbol of a channel of the PUCCH and PUSCH, which starts earliest. When the time condition is met, UCI (Uplink Control Information ) carried on the PUCCH is transferred to PUSCH for transmission without transmitting the PUCCH, thereby avoiding simultaneous transmission of PUCCH and PUSCH. When there is an overlap in time domain between PUCCHs carrying UCI, it is also necessary to make a determination as to whether or not a first symbol of a channel starting earliest in the overlapped PUCCHs satisfies a predefined time condition. When the time condition is met, UCI on a plurality of PUCCHs can be transmitted in a combined manner, and UCI on a plurality of PUCCHs can be simultaneously transmitted on one PUCCH channel, thereby avoiding simultaneous transmission of a plurality of PUCCHs.

In R15, it is defined that no failure to satisfy timeline occurs, i.e., the failure to satisfy timeline is a misschedule, and no behavior is performed. Accordingly, the base station needs to ensure that the time line is always satisfied between the overlapped channels during scheduling and configuration. The Timeline is determined according to transmission parameters, processing capacity, subcarrier spacing and the like of a plurality of channels overlapped in time domain according to specific rules in a protocol, and has different Timeline definitions for different situations.

When there is time domain overlapping of a plurality of PUCCHs and time domain overlapping between the PUCCHs and the PUSCHs, the overlapped PUCCHs are processed according to a multiplexing transmission rule between the PUCCHs to obtain one PUCCH, and then the time domain overlapping between the one PUCCH and the PUSCH is processed.

Specifically, HARQ-ACK (Hybrid automatic repeat request acknowledgement ) carried on PUCCH may be transferred to PUSCH for transmission; the CSI (Channel State Information ) carried on the PUCCH may be transferred to PUSCH for transmission when the PUSCH carrying UCI is selected to contain no CSI (e.g., a-CSI (Aperiodic CSI), SP-CSI (Semi-Persistent CSI)), or else discarded. Specifically, when SR (Scheduling Request ) is carried on PUCCH (when the state of SR is positive, it means that there is a scheduling request by a terminal, and when SR is transmitted on PUCCH alone, if the state of SR is negative (negative), it means that there is no scheduling request by a terminal, and when no transmission is performed on PUCCH resources corresponding to SR, if UL-SCH (Uplink Shared Channel ) is included in PUSCH overlapping with PUCCH, SR is discarded, and PUSCH is transmitted; if the PUSCH does not contain the UL-SCH, the PUSCH overlapped with the PUCCH is discarded, and the SR is transmitted on the PUCCH.

When there is overlap of PUCCH with multiple PUSCHs, PUSCH containing a-CSI may be preferentially selected as PUSCH carrying UCI on PUCCH; when there is no PUSCH carrying a-CSI, a PUSCH having PDCCH (or DCI (Downlink Control Information, downlink control information), which is a specific format used for PDCCH transmission, and thus two considered conceptually equivalent) scheduling is preferentially selected; if the PUSCH types on multiple carriers are consistent (e.g., both are scheduled with PDCCH (Physical downlink control channel, physical downlink control channel), or both are not scheduled with PDCCH), then the PUSCH on the carrier with the smallest carrier number is selected for carrying UCI.

For one carrier, a phenomenon of overlap between two or more PUSCHs in the time domain may occur. At this time, one PUSCH transmission needs to be selected according to a rule, and the other PUSCH transmissions are discarded.

For example, on the same carrier (specifically, it may be that a certain active BWP (Bandwidth Part) of this carrier), there may be a case where multiple PUSCHs are overlapped in the time domain as shown in fig. 1, where the PUSCH earlier in the beginning may be cancelled halfway by the PUSCH overlapped with the PUSCH later in the beginning, that is, because the terminal receives the UL-SCH or TB (Transport Block) that needs to be transmitted on the PUSCH later in the beginning (for example, MAC (Medium Access Control, media access control) layer of the terminal sends a PDU (Protocol Data Unit ) transmitted on the PUSCH earlier in the beginning to the terminal, and then sends a PDU (corresponding to the physical layer, that is, UL-SCH or TB transmitted on the PUSCH) transmitted on the PUSCH later in the beginning, and the terminal needs to cancel (if the PUSCH earlier in the beginning has not yet started to be transmitted) or stop (if the PUSCH earlier in the beginning has started to be transmitted) the PUSCH earlier in the beginning, and prepare to transmit the PUSCH later in the beginning.

When the PUCCH overlaps with the PUSCH with the earlier starting point in time, so that UCI needs to be transferred to the PUSCH with the earlier starting point for transmission, if the PUSCH with the earlier starting point is stopped or cancelled by the subsequent PUSCH, UCI thereon cannot be normally transmitted to the base station side, so that the base station cannot timely and correctly obtain feedback information such as HARQ-ACK, CSI, SR of the downlink transmission that has occurred.

There is no clear method how to solve the UCI discarding problem in the above case.

Detailed Description

The following description of the embodiments of the present invention will be made clearly and fully with reference to the accompanying drawings, in which it is evident that the embodiments described are some, but not all embodiments of the invention. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.

Referring to fig. 2, fig. 2 is a flowchart of an information transmission method provided in an embodiment of the present invention, which is applied to a terminal, as shown in fig. 2, and includes the following steps:

Step 201, when a PUCCH carrying UCI overlaps with at least one PUSCH in the time domain, selecting a first PUSCH from the at least one PUSCH, where the first PUSCH is used to carry the UCI.

In the embodiment of the present invention, how to select the first PUSCH is not specifically limited.

For example, if there are a plurality of PUSCHs overlapping with PUCCHs carrying UCI at the same time, the terminal selects one PUSCH carrying UCI among the plurality of PUSCHs according to a predetermined rule. The specific rule may be:

for example, if there is a PUSCH carrying a-CSI, the terminal preferentially selects the PUSCH carrying a-CSI; if the PUSCH carrying the A-CSI does not exist, but the PUSCH scheduled by the PDCCH exists and the PUSCH scheduled by the PDCCH does not exist, the PUSCH scheduled by the PDCCH is preferentially selected; when the same type of PUSCH exists on multiple carriers (for example, PUSCH scheduled by both PDCCH or PUSCH scheduled by both PDCCH), selecting PUSCH on carrier with the smallest carrier number; if there are multiple PUSCHs of TDM (Time division multiplexing ) (i.e., non-overlapping in time domain) overlapping with PUCCH on the carrier with the smallest selected carrier number, the PUSCH with the earliest start time is selected.

In the embodiment of the present invention, the specific selection rule for selecting the first PUSCH is not limited to the above rule, as long as the network side device and the terminal use the same rule.

Step 202, if the first PUSCH and the second PUSCH overlap in time domain on the same carrier, transmitting the UCI on the first PUSCH and the second PUSCH; or if the first PUSCH and the second PUSCH overlap in time domain on the same carrier, when the first PUSCH is stopped or cancelled, the UCI is transmitted on the second PUSCH.

Wherein, when the UCI is transmitted only on a second PUSCH, UCI uploaded on the second PUSCH is transferred to the second PUSCH on the first PUSCH.

In the embodiment of the present invention, the start symbol of the second PUSCH is not earlier than the start symbol of the first PUSCH.

Optionally, the first PUSCH and the second PUSCH may be the following types of PUSCHs:

the first PUSCH and the second PUSCH are CG PUSCH; or alternatively, the process may be performed,

the first PUSCH and the second PUSCH are both PUSCHs with PDCCH scheduling.

Optionally, the first PUSCH and the second PUSCH are PUSCHs including UL-SCH or TB transmissions.

In the embodiment of the present invention, the first PUSCH may be stopped or cancelled by the second PUSCH. The first PUSCH is stopped or cancelled when at least one of:

(1) When the second PUSCH is a PUSCH scheduled with a PDCCH, the first PUSCH is stopped or cancelled.

In this case, the second PUSCH is a PUSCH scheduled with a PDCCH, and may be equivalent to the second PUSCH being a PUSCH scheduled with DCI (Downlink Control Information ), where the DCI is a specific format used for PDCCH transmission.

(2) When the second PUSCH has UL-SCH or TB to be transmitted, the first PUSCH is stopped or cancelled; or when the time when the second PUSCH obtains the UL-SCH or the TB is later than the time when the first PUSCH obtains the UL-SCH or the TB, the first PUSCH is stopped or cancelled. The time when the physical layer obtains the data to be transmitted on one PUSCH, that is, the time when the physical layer starts to know that there is data to be transmitted on one PUSCH, the time when the MAC layer notifies the physical layer of the PDU corresponding to the transmission on one PUSCH, or the time when the physical layer receives the PDU issued by the MAC, where the PDU is defined by the MAC layer, and the PHY corresponds to the UL-SCH or TB.

Optionally, in an embodiment of the present invention, the UCI includes at least one of the following information: HARQ-ACK, CSI, SR.

In the embodiment of the present invention, the transmission of the UCI on the first PUSCH and the second PUSCH includes at least one of the following cases:

(1) And when the UCI at least comprises HARQ-ACK, transmitting the UCI on the first PUSCH and the second PUSCH, or transmitting the HARQ-ACK on the first PUSCH and the second PUSCH.

That is, in this case, if one or both of CSI and SR are included in the UCI in addition to HARQ-ACK, one way is to transmit all UCI (including CSI and SR) on the first PUSCH and the second PUSCH, the UCI transmission overhead on PUSCH is relatively large, but it can be avoided that all UCI is discarded; another way is to discard one or both of CSI and SR, and only transmit HARQ-ACKs on the first PUSCH and the second PUSCH, mainly considering that HARQ-ACKs are more important than CSI and SR, in order to reduce UCI transmission overhead on PUSCH, only more important UCI may be transmitted.

(2) When the UCI contains at least CSI, if CSI transmission is also contained on at least one PUSCH of the first PUSCH and the second PUSCH, it is determined that CSI in the UCI is discarded when the UCI is transmitted on the PUSCH containing CSI.

For example, in this case, if CSI transmission is also included on the first PUSCH and the second PUSCH (CSI may be a-CSI or SP-CSI), CSI in the UCI may be removed when the first PUSCH and the second PUSCH transmit the UCI, because CSI-related information is already carried on PUSCH itself, and UCI of the same type need not be repeatedly carried, i.e., UCI other than CSI in the UCI may be transmitted on the first PUSCH and the second PUSCH. For example, the UCI includes HARQ-ACK in addition to CSI, and then the HARQ-ACK is transmitted on the first PUSCH and the second PUSCH.

(3) When the UCI includes at least SR, the SR is discarded.

That is, in this case, if the UCI contains only SRs, the UCI is discarded without transmission, and if the UCI contains other UCI such as HARQ-ACK and/or CSI along with the SR, the SRs in the UCI may be removed when the first PUSCH and the second PUSCH transmit the UCI, and other UCI except for the SR in the UCI may be transmitted only on the first PUSCH and the second PUSCH, such as HARQ-ACK and/or CSI.

The above (1) - (3) may be used alone or in combination, for example, (2) and (3) may be used in combination, and when HARQ-ACK, CSI and SR are included in the UCI, the SR is discarded according to (3), and according to (2), if CSI is also included on the first PUSCH and the second PUSCH, the CSI is discarded, HARQ-ACK is transmitted only on the first PUSCH and the second PUSCH, and if CSI is not included on the first PUSCH and the second PUSCH, HARQ-ACK and CSI are transmitted on the first PUSCH and the second PUSCH.

In the embodiment of the present invention, the transmitting the UCI on the second PUSCH includes at least one of the following cases:

(1) And when the UCI at least contains HARQ-ACK, transmitting the UCI on the second PUSCH or transmitting the HARQ-ACK on the second PUSCH.

That is, in this case, if one or both of CSI and SR are included in the UCI in addition to HARQ-ACK, one way is to transmit all UCI (including CSI and SR) on the second PUSCH, the UCI transmission overhead on the PUSCH is relatively large, but it is possible to avoid all UCI being discarded, and the other way is to discard one or both of CSI and SR, HARQ-ACK is transmitted only on the second PUSCH, mainly considering that HARQ-ACK is higher in importance than CSI and SR, and only the UCI of relatively great importance may be transmitted in order to reduce the UCI transmission overhead on the PUSCH.

(2) And when the UCI at least contains the CSI, discarding the CSI in the UCI if the UCI also contains the CSI transmission on the second PUSCH.

In this case, if CSI transmission is also included on the second PUSCH (CSI may be a-CSI or SP-CSI), CSI in the UCI may be removed when the second PUSCH transmits the UCI, because CSI-related information is already carried on PUSCH itself, and UCI of the same type need not be repeatedly carried, i.e., UCI other than CSI in the UCI may be transmitted on the second PUSCH. For example, the UCI includes HARQ-ACK in addition to CSI, and then the HARQ-ACK is transmitted on the second PUSCH.

(3) When the UCI includes at least SR, the SR is discarded.

That is, in this case, if the UCI includes only SR, the UCI is discarded without transmission, and if the UCI includes SR while other UCI such as HARQ-ACK and/or CSI is also included, the SR in the UCI may be removed when the UCI is transmitted on the second PUSCH, and other UCI than SR in the UCI such as HARQ-ACK and/or CSI may be transmitted only on the second PUSCH.

The above (1) - (3) may be used alone or in combination, for example, (2) and (3) may be combined, and when the UCI includes HARQ-ACK, CSI and SR, the SR is discarded according to (3), and according to (2), if the CSI is also included on the second PUSCH, the HARQ-ACK is transmitted only on the second PUSCH, and if the CSI is not included on the second PUSCH, the HARQ-ACK and CSI are transmitted on the second PUSCH.

In the embodiment of the present invention, the PUCCH overlaps with the second PUSCH in the time domain, or the PUCCH does not overlap with the second PUSCH in the time domain.

In the embodiment of the present invention, the PUCCH and the first PUSCH are on the same carrier, or the PUCCH and the first PUSCH are on different carriers.

That is, in the application scenario of the embodiment of the present invention, the PUCCH and the first PUSCH overlap in the time domain on the same or different carriers, and the first PUSCH and the second PUSCH overlap in the time domain on the same carrier, where the above method may be used regardless of whether the second PUSCH overlaps in the time domain or not. In particular, if there is also an overlap between the second PUSCH and the PUCCH in the time domain, it is explained that according to the rule of selection of the PUSCH transmitting UCI, it is selected not to transmit UCI by the second PUSCH (otherwise, this PUSCH would not be the second PUSCH if selected as the PUSCH transmitting UCI, but would be the first PUSCH), but to select other PUSCH transmitting UCI to obtain other PUSCH as the first PUSCH.

It should be noted that, the "carrier" in the embodiment of the present invention may also be replaced by concepts such as a serving cell, BWP (Bandwidth Part), a carrier on the serving cell, and BWP on a carrier on the serving cell.

As can be seen from the above, in the embodiment of the present invention, when the PUCCH carrying UCI overlaps with at least one PUSCH in the time domain, if a first PUSCH selected by a terminal according to a predetermined rule for carrying the UCI overlaps with a second PUSCH in the time domain on the same carrier, the UCI is transmitted on the first PUSCH and the second PUSCH; or if the first PUSCH and the second PUSCH overlap in time domain on the same carrier, when the first PUSCH is stopped or cancelled, the UCI is transmitted on the second PUSCH. Therefore, by using the scheme in the embodiment of the invention, when the first PUSCH carrying the UCI is stopped or cancelled, normal transmission of the UCI can be ensured, thereby ensuring the transmission performance of the UCI.

Referring to fig. 3, fig. 3 is a flowchart of an information transmission method provided by an embodiment of the present invention, which is applied to a network side device, as shown in fig. 3, and includes the following steps:

step 301, when a PUCCH carrying UCI overlaps at least one PUSCH in a time domain, if a first PUSCH selected by a terminal for carrying the UCI overlaps a second PUSCH in the same carrier in the time domain, a network side device determines that the UCI is transmitted on the first PUSCH and the second PUSCH; or alternatively, the process may be performed,

when a PUCCH carrying UCI overlaps with at least one PUSCH in a time domain, if a first PUSCH used for carrying the UCI selected by a terminal overlaps with a second PUSCH in the same carrier in the time domain, under the condition that the first PUSCH is stopped or cancelled, network side equipment determines that the UCI is transmitted on the second PUSCH.

Wherein, when the UCI is transmitted only on the second PUSCH, UCI uploaded on the second PUSCH is transferred from the first PUSCH to the second PUSCH.

the first PUSCH and the second PUSCH are both PUSCHs with PDCCH scheduling.

Optionally, in the embodiment of the present invention, the first PUSCH may be stopped or cancelled by the second PUSCH, and may also be stopped or cancelled by another PUSCH overlapping with the first PUSCH in the same time domain on the carrier. When it is determined that the first PUSCH is stopped or cancelled in at least one of the following cases:

(1) And when the second PUSCH is the PUSCH with the PDCCH schedule, determining that the first PUSCH is stopped or cancelled.

In this case, the second PUSCH is a PUSCH scheduled with a PDCCH, and may be equivalent to the second PUSCH being a PUSCH scheduled with a DCI, where the DCI is a specific format used for PDCCH transmission.

(2) When the second PUSCH has an UL-SCH or TB to be transmitted, determining that the first PUSCH is stopped or cancelled; or when the time when the second PUSCH obtains the UL-SCH or the TB is later than the time when the first PUSCH obtains the UL-SCH or the TB, determining that the first PUSCH is stopped or cancelled.

In the embodiment of the present invention, determining to transmit the UCI on the first PUSCH and the second PUSCH includes at least one of the following cases:

(1) And when the UCI at least contains HARQ-ACK, determining to transmit the UCI on the first PUSCH and the second PUSCH, or determining to transmit the HARQ-ACK on the first PUSCH and the second PUSCH.

That is, in this case, if one or both of CSI and SR are included in the UCI in addition to the HARQ-ACK, it is determined to discard one or both of CSI and SR. Alternatively, if one or both of CSI and SR are included in the UCI in addition to the HARQ-ACK, it is determined that all UCI (including CSI and SR) is transmitted on the first PUSCH and the second PUSCH.

In this case, for example, if CSI transmission (CSI may be a-CSI or SP-CSI) is also included on the first PUSCH and the second PUSCH, UCI other than CSI among the UCI is determined to be transmitted on the first PUSCH and the second PUSCH. For example, the UCI includes HARQ-ACK in addition to CSI, and then it is determined that the HARQ-ACK is transmitted on the first PUSCH and the second PUSCH.

(3) When the UCI includes at least an SR, it is determined that the SR is discarded.

That is, in this case, if the UCI includes only SR, it is determined that the UCI is discarded; if the UCI includes SR and also includes other UCI, such as HARQ-ACK and/or CSI, then it is determined that other UCI than SR, such as HARQ-ACK and/or CSI, of the UCI is transmitted only on the first PUSCH and the second PUSCH when the UCI is transmitted on the first PUSCH and the second PUSCH.

In the embodiment of the present invention, determining that the UCI is transmitted on the second PUSCH includes at least one of the following cases:

(1) And when the UCI at least contains HARQ-ACK, determining to transmit the UCI on the second PUSCH or determining to transmit the HARQ-ACK on the second PUSCH.

That is, in this case, if one or both of CSI and SR are included in the UCI in addition to the HARQ-ACK, it is determined to discard one or both of CSI and SR. Alternatively, if one or both of CSI and SR are included in the UCI in addition to the HARQ-ACK, it is determined that all UCI (including CSI and SR) is transmitted on the second PUSCH.

(2) And when the UCI at least contains the CSI, if the CSI transmission is also contained on the second PUSCH, determining that the CSI in the UCI is discarded.

That is, in this case, if CSI (CSI may be a-CSI or SP-CSI) transmission is also included on the second PUSCH, UCI other than CSI among the UCI is determined to be transmitted on the second PUSCH. For example, the UCI includes HARQ-ACK in addition to CSI, and then it is determined that the HARQ-ACK is transmitted on the second PUSCH.

That is, in this case, if the UCI includes only SR, it is determined that the UCI is discarded; if the UCI includes SR and also includes other UCI, such as HARQ-ACK and/or CSI, then, when the UCI is transmitted on the second PUSCH, it is determined that other UCI, such as HARQ-ACK and/or CSI, among the UCI except SR is transmitted only on the second PUSCH.

It should be noted that, the "carrier" in the embodiment of the present invention may also be replaced by concepts such as a serving cell, BWP, a carrier on a serving cell, and BWP on a carrier on a serving cell.

In the embodiment of the present invention, the network side device may be a base station, for example.

As can be seen from the above, in the embodiment of the present invention, when the PUCCH carrying UCI overlaps with at least one PUSCH in the time domain, if a first PUSCH selected by a terminal for carrying the UCI overlaps with a second PUSCH in the same carrier in the time domain, the UCI is transmitted on the first PUSCH and the second PUSCH; or if the first PUSCH and the second PUSCH overlap in time domain on the same carrier, when the first PUSCH is stopped or cancelled, the UCI is transmitted on the second PUSCH. Therefore, by using the scheme in the embodiment of the invention, when the first PUSCH carrying the UCI is stopped or cancelled, normal transmission of the UCI can be ensured, thereby ensuring the transmission performance of the UCI.

As shown in fig. 4, assuming that the terminal is configured with 2 CG configurations, time domain resources of the two CG configurations overlap, PUSCH of CG1 overlaps with one PUCCH carrying HARQ-ACK, and priorities of the CG1PUSCH and PUCCH are the same, for example, both correspond to high priorities, and timeline for transferring HARQ-ACK on PUCCH to PUSCH transmission is satisfied between PUCCH and CG1PUSCH, the terminal determines to transfer HARQ-ACK on PUCCH to CG1PUSCH for transmission, without transmitting PUCCH, thereby avoiding simultaneous transmission of multiple uplink channels. However, because there is overlap in time domain resources between CG1PUSCH and CG2PUSCH, assuming that CG1PUSCH and CG2PUSCH also have the same priority, for example, both have high priority, the terminal can only transmit one PUSCH at the overlapped part of CG1PUSCH and CG2PUSCH, for example, according to the front-back sequence of the PDU (UL-SCH or TB transmitted on physical layer, i.e. PUSCH) transmitted on CG1PUSCH and CG2PUSCH corresponding to the terminal sent to the terminal by the MAC layer of the terminal, the PUSCH corresponding to the last received PDU is more prioritized, assuming that the PDU arrival time of CG1PUSCH is earlier and the PDU arrival time of CG2PUSCH is later, as shown in fig. 4:

At the terminal side, the terminal receives the PDU corresponding to the transmission on the CG1 PUSCH at an earlier time, and does not know that the CG2 PUSCH is to be transmitted before the PDU corresponding to the transmission on the CG2 PUSCH is not received, so that the CG1 PUSCH is determined to be required to be transmitted, and the HARQ-ACK of the PUCCH is transferred to the CG1 PUSCH to be transmitted according to the overlapping processing rule (the time of multiplexing transmission is met) of the PUCCH and the CG1 PUSCH. And after the CG1 PUSCH carries the HARQ-ACK and starts to transmit, determining that the CG2 PUSCH needs to be transmitted because the PDU corresponding to the transmission on the CG2 PUSCH is received. In order to avoid overlapping transmission of two PUSCHs, transmission of CG1 PUSCH is required to be stopped, preparation of CG2 PUSCH data is started, and CG2 PUSCH is transmitted on a resource corresponding to CG2 PUSCH, wherein when CG2 PUSCH is prepared, a terminal needs to transfer HARQ-ACK originally transferred from PUCCH to CG1 PUSCH for transmission to CG2 PUSCH, so that HARQ-ACK cannot be normally transmitted to a base station due to the fact that CG1 PUSCH is stopped.

For the base station side, since it cannot be determined whether CG1 PUSCH and CG2 PUSCH are transmitted (because whether the terminal will transmit which CG PUSCH depends on whether there is corresponding data to be transmitted in a buffer (buffer) at the terminal side, and the base station cannot know the buffer condition of the terminal), the base station needs to detect two PUSCHs on resources corresponding to CG1 PUSCH and CG2 PUSCH respectively, and see the actual receiving condition to determine whether there is corresponding transmission.

For example, when attempting to receive CG1PUSCH on a resource corresponding to CG1PUSCH, the base station determines that HARQ-ACK on PUCCH is transferred to CG1PUSCH for transmission based on the same principle as that of the terminal side, in accordance with the presence of CG1 PUSCH. Therefore, when attempting to receive CG1PUSCH, the base station assumes that HARQ-ACK is carried therein for reception, but because the terminal side stops transmission of CG1PUSCH halfway, the base station side fails to receive this CG1PUSCH or determines DTX (Discontinuous Reception ), and thus considers that CG1PUSCH is not transmitted or stopped halfway, and the base station also needs to attempt to receive CG2 PUSCH on the resource corresponding to CG2 PUSCH.

Also, like the case where CG2 PUSCH exists on the terminal side, it is judged that HARQ-ACK is required to be transmitted on CG2 PUSCH, so when attempting to receive CG2 PUSCH, the base station assumes that HARQ-ACK is carried therein for reception, and this reception is due to the transmission behavior on the symbol terminal side, so that eventually the base station normally receives CG2 PUSCH and obtains HARQ-ACK therefrom. In the above process, when the base station determines that the CG1PUSCH is not normally received, since the base station does not know that the terminal side stops transmitting the CG1PUSCH, but no PDU is transmitted on the CG1PUSCH at all (if this is the case, in fig. 4, there is no overlap between the CG1PUSCH and the PUCCH at the terminal side, and the terminal only needs to transmit the PUCCH and the CG2 PUSCH on non-overlapping resources, respectively), the base station may further perform detection on the PUCCH resources to obtain the result as DTX, thereby determining that the terminal side actually has the CG1PUSCH transmission, and because the CG1PUSCH overlapping with the CG2 PUSCH is stopped or cancelled.

In the above embodiment, the terminal actually transmits HARQ-ACK on both CG1PUSCH and CG2 PUSCH, that is, UCI on PUCCH is transmitted on both the first PUSCH and the second PUSCH. Similarly, the base station also assumes that there is HARQ-ACK reception when receiving CG1PUSCH and CG2 PUSCH.

Taking the time when the PDU transmitted on the CG2 PUSCH is received as the time when the CG1PUSCH is stopped as an example in fig. 4, it is not excluded that a certain buffering time is required to stop the CG1PUSCH in the actual implementation process, that is, the time when the CG1PUSCH is stopped may be later than the time indicated by the dashed line 41 in fig. 4, but it is ensured that the CG1PUSCH is stopped before the start of the CG2 PUSCH, so as to avoid the simultaneous transmission of the two.

In the above embodiment, the arrival time of the PDU transmitted on the CG2 PUSCH is later than the start time of the CG1PUSCH, which is only an example, and the arrival time of the PDU transmitted on the CG2 PUSCH may be earlier than the start time of the CG1PUSCH, where the CG1PUSCH may be stopped or cancelled before transmission, so that there is no possibility that the CG1PUSCH is stopped halfway after transmitting several symbols, and when the terminal receives the PDU transmitted on the CG2 PUSCH, it only needs to stop the preparation (such as encoding, modulation, scrambling, etc. pre-processing) process of the information transmitted on the CG1PUSCH, and transfer the HARQ-ACK originally mapped to the CG1PUSCH to the CG2 PUSCH for transmission along with the data transmitted on the CG2 PUSCH. The base station side, however, always detects on multiple resources according to the steps in the above embodiments, because the PDU arrival time of the terminal side corresponding to CG1 and CG2 PUSCHs is not known.

In the above embodiment, the CG1 PUSCH and the CG2 PUSCH are PUSCHs that overlap each other on the same carrier, and the PUSCH (CG 1 PUSCH and CG2 PUSCH) and the PUCCH may be performed on the same carrier or on different carriers, in both cases, in the manner of the above embodiment. The same applies if there are PUSCHs overlapping PUCCHs on multiple CCs at the same time, where CG1 PUSCH in the embodiment is one PUSCH selected on multiple CCs according to the selection rule of the PUSCH carrying UCI.

In the above embodiment, CG1 PUSCH and/or CG2 PUSCH is replaced with DG (Dynamic Grant) PUSCH, and the same manner as described above applies.

In the above embodiment, only the PUCCH overlaps with the CG1 PUSCH, but not with the CG2 PUSCH. The same applies to the case where the PUCCH overlaps both CG1 PUSCH and CG2 PUSCH, and the same applies to the case where the PUCCH overlaps a plurality of PUSCHs when one or a plurality of CG PUSCHs are replaced with DG PUSCHs.

In the above embodiment, when the HARQ-ACK on the PUCCH is replaced with CSI, or replaced with HARQ-ACK and CSI, or replaced with CSI and SR, or replaced with HARQ-ACK, CSI and SR, the same may be performed in the above manner. In contrast, for the case of containing SR, the SR is not transferred to PUSCH according to the multiplexing transmission rule of PUCCH and PUSCH, and may be directly discarded, i.e., other UCI is transferred to PUSCH.

In the above embodiment, the same applies when the channels are all assumed to be low priority channels. The PUCCH and PUSCH may also be of different priorities when supporting PUCCH and PUSCH multiplexed transmissions of different priorities. When determining which PUSCH to transmit only according to PDU arrival time between PUSCHs supporting overlapping time domain resources on the same carrier (i.e., determining who to transmit according to which PUSCH the last received PDU is regardless of the priorities of the first PUSCH and the second PUSCH), the first PUSCH and the second PUSCH may also be of different priorities.

As can be seen from the above description, in the embodiment of the present invention, UCI is also transmitted on a PUSCH overlapping with a PUSCH carrying UCI of a PUCCH, or UCI carried on a PUSCH on which UCI carrying PUCCH is stopped is transmitted on other PUSCHs when the PUSCH carrying UCI of a PUCCH is stopped by other PUSCHs, so that the behavior that UCI from PUCCH carried by one PUSCH is discarded when the PUSCH is stopped by other PUSCHs is avoided, and the transmission performance of UCI is ensured.
