Technical field

The present disclosure relates to the field of communication technology, and in particular, to an information transmission method, device, equipment, and computer-readable storage medium.

Background technique

In the 5G R15 New Radio (NR), from the perspective of reducing the Peak to Average Power Ratio (PAPR) and Connection Management (CM), it does not support the Physical Uplink Control Channel (Physical Uplink Control Channel). , PUCCH) and physical uplink shared channel (Physical Uplink Shared Channel, PUSCH) simultaneous transmission (time domain resource overlap), and multiple overlapping PUCCHs are not supported for simultaneous transmission on the same carrier.

When all or part of the symbols of a PUCCH and a PUSCH overlap, it is necessary to judge whether the first symbol of the earliest channel in the PUCCH and the PUSCH meets the predefined timeline. When the time condition is met, the uplink control information (Uplink Control Information, UCI) carried on the PUCCH is transferred to the PUSCH for transmission instead of the PUCCH, thereby avoiding the simultaneous transmission of the PUCCH and the PUSCH. When the PUCCHs carrying UCI overlap in the time domain, it is also necessary to determine whether the first symbol of the earliest channel in the overlapped PUCCH meets the predefined time condition. When the time condition is met, combined transmission of UCI on multiple PUCCHs can be performed, and UCI on multiple PUCCHs can be simultaneously transmitted on one PUCCH channel, thereby avoiding simultaneous transmission of multiple PUCCHs.

It is defined in R15 that there will be no unsatisfied timeline, that is, the unsatisfied timeline is wrong scheduling and no execution behavior. Correspondingly, the base station needs to ensure that the timeline is always satisfied between overlapping channels during scheduling and configuration. Among them, Timeline is determined according to the specific provisions in the protocol based on the transmission parameters, processing capabilities, and subcarrier spacing of multiple channels that overlap in the time domain. There are different timeline definitions for different situations.

When there are multiple PUCCH overlaps in the time domain and the time domain overlap between PUCCH and PUSCH at the same time, first process the overlapped PUCCH according to the multiplexing transmission rule between PUCCH to obtain a PUCCH, and then process this PUCCH and PUSCH The time domain overlaps between.

Specifically, the hybrid automatic repeat request acknowledgement (HARQ-ACK) carried on the PUCCH can be transferred to the PUSCH for transmission; the channel state information (CSI) carried on the PUCCH is selected to carry UCI When the PUSCH does not include CSI (for example, aperiodic CSI (Aperiodic CSI, A-CSI), semi-persistent CSI (Semi-Persistent CSI, SP-CSI)), it can be transferred to the PUSCH for transmission, otherwise it is discarded. In particular, a scheduling request (Scheduling Request, SR) is carried on the PUCCH (the SR status is positive at this time, indicating that the terminal has a scheduling request. When the SR is transmitted separately on the PUCCH, if the SR status is negative, Indicates that the terminal does not have a scheduling request, and when the PUCCH resource corresponding to the SR is not sent at this time), if the PUSCH overlapping with the PUCCH includes an uplink shared channel (Uplink Shared Channel, UL-SCH), the SR is discarded and the PUSCH is transmitted; If the PUSCH does not include the UL-SCH, the PUSCH overlapping with the PUCCH is discarded, and the SR is transmitted on the PUCCH.

When PUCCH overlaps with multiple PUSCHs, the PUSCH containing A-CSI can be preferentially selected as the PUSCH carrying UCI on the PUCCH; when there is no PUSCH carrying A-CSI, the PDCCH (or Downlink Control Information (Downlink Control Information) Information, DCI), DCI is the specific format used for PDCCH transmission, so the two PUSCHs that are considered conceptually equivalent) are scheduled PUSCH; if the PUSCH types on multiple carriers are the same (for example, they all have a physical downlink control channel). , PDCCH) scheduling, or all without PDCCH scheduling), the PUSCH on the carrier with the smallest carrier number is selected to carry UCI.

For one carrier, there may be overlap between two or more PUSCHs in the time domain. At this time, one of the PUSCHs needs to be selected for transmission according to the rules, and the other PUSCHs are discarded.

For example, on the same carrier (specifically, it may be on a certain active bandwidth part (Bandwidth Part, BWP) of this carrier), there may be a situation where multiple PUSCHs overlap in the time domain as shown in Figure 1, where the starting point is relatively high. The early PUSCH may be cancelled halfway by the PUSCH that overlaps with the late start, that is, because the terminal receives the UL-SCH or transport block (Transport Block, TB) that needs to be transmitted on the late PUSCH (for example, the terminal’s After the Medium Access Control (MAC) layer sends a protocol data unit (Protocol Data Unit, PDU) transmitted on the PUSCH with an earlier starting point to the terminal, it sends another transmission on the PUSCH with a later starting point. PDUs. These PDUs correspond to the physical layer, which is the UL-SCH or TB transmitted on the PUSCH. The terminal needs to cancel (if the PUSCH with an earlier starting point has not started transmission) or stop (if the PUSCH with an earlier starting point has already started transmission) ) The PUSCH with an earlier start point is prepared to transmit the PUSCH with a later start point instead.

When the PUCCH and a PUSCH with an earlier starting point overlap in time, UCI needs to be transferred to the PUSCH with an earlier starting point for transmission. If the PUSCH with an earlier starting point is stopped or cancelled by the subsequent PUSCH, the UCI on it is also It cannot be transmitted to the base station side normally, so that the base station cannot obtain the HARQ-ACK, CSI, SR and other feedback information of the downlink transmission that has occurred in a timely and correct manner.

In the related art, there is still no clear method to solve the UCI discarded problem in the above situation.

Detailed ways

The technical solutions in the embodiments of the present disclosure will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present disclosure. Obviously, the described embodiments are part of the embodiments of the present disclosure, rather than all of the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present disclosure.

Referring to FIG. 2, FIG. 2 is a flowchart of an information transmission method provided by an embodiment of the present disclosure, which is applied to a terminal. As shown in FIG. 2, it includes the following steps:

Step 201: When a PUCCH carrying UCI overlaps with at least one PUSCH in the time domain, a first PUSCH is selected from at least one PUSCH, and the first PUSCH is used to carry the UCI.

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

For example, if multiple PUSCHs and PUCCHs carrying UCI overlap at the same time, the terminal selects one PUSCH to carry UCI among the multiple PUSCHs according to a predetermined rule. Among them, the specific rules can be:

For example, if there is a PUSCH that carries A-CSI, the terminal prefers to choose the PUSCH that carries A-CSI; if there is no PUSCH that carries A-CSI, but there is a PUSCH scheduled by PDCCH and a PUSCH without PDCCH scheduling, then PDCCH is preferred Scheduled PUSCH; when there are PUSCHs of the same type on multiple carriers (for example, all PUSCHs scheduled with PDCCH, or all PUSCHs without PDCCH scheduling), select the PUSCH on the carrier with the smallest carrier number; if you are selecting If there are multiple time division multiplexing (TDM) (non-overlapping in the real-time domain) PUSCH and PUCCH on the carrier with the smallest carrier number, the PUSCH with the earliest start time is selected.

It should be noted that, in the embodiments of the present disclosure, the specific selection rule for selecting the first PUSCH may not be limited to the foregoing rules, 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 the time domain on the same carrier, transmit the UCI on the first PUSCH and the second PUSCH; or, if the first PUSCH and the second PUSCH are Two PUSCHs overlap in time domain on the same carrier, and when the first PUSCH is stopped or cancelled, the UCI is transmitted on the second PUSCH.

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

In the embodiment of the present disclosure, 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 PUSCH:

Both the first PUSCH and the second PUSCH are CG PUSCH; or,

Both the first PUSCH and the second PUSCH are PUSCHs scheduled with PDCCH.

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

In the embodiment of the present disclosure, the first PUSCH may be stopped or cancelled by the second PUSCH. When in at least one of the following situations, the first PUSCH is stopped or cancelled:

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

In this case, the second PUSCH is a PUSCH scheduled with PDCCH, which may be equivalent to that the second PUSCH is a PUSCH scheduled with downlink control information (Downlink Control Information, DCI), where DCI is a specific method used for PDCCH transmission. Format.

(2) When the second PUSCH has UL-SCH or TB to be transmitted, the first PUSCH is stopped or cancelled; or, when the second PUSCH obtains the UL-SCH or TB later than the first PUSCH When a PUSCH obtains UL-SCH or TB, the first PUSCH is stopped or cancelled. The time when the UL-SCH or TB is obtained can be the time when the physical layer obtains the data to be transmitted on a PUSCH. At this moment, the physical layer knows that there is data to be transmitted on a PUSCH. This time can be the MAC layer corresponding The time when the PDU transmitted on a certain PUSCH is notified to the physical layer, or when the physical layer receives the PDU sent by the MAC, and the PDU is the definition of the MAC layer, which corresponds to UL-SCH or TB in the PHY.

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

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

(1) When the UCI contains at least HARQ-ACK, the UCI is transmitted on the first PUSCH and the second PUSCH, or the UCI is transmitted on the first PUSCH and the second PUSCH HARQ-ACK.

That is, in this case, in addition to HARQ-ACK, if the UCI also includes one or two of CSI and SR, one way is to combine all UCIs (including CSI and SR). When transmitting on the first PUSCH and the second PUSCH, the UCI transmission overhead on PUSCH is relatively large, but it can avoid all UCI being discarded; the other way is to discard one or both of CSI and SR, and only in the first The HARQ-ACK is transmitted on the PUSCH and the second PUSCH, mainly considering that the HARQ-ACK is more important than the CSI and SR. In order to reduce the UCI transmission overhead on the PUSCH, only the more important UCI can be transmitted.

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

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), then the first PUSCH and the second PUSCH When the second PUSCH transmits the UCI, the CSI in the UCI can be removed, because the CSI-related information is already carried on the PUSCH itself, and there is no need to carry the same type of UCI repeatedly, that is, the UCI in addition to the CSI UCI can be transmitted on the first PUSCH and the second PUSCH. For example, the UCI includes HARQ-ACK in addition to CSI. Then, the HARQ-ACK is transmitted on the first PUSCH and the second PUSCH.

(3) When the UCI contains at least SR, discard the SR.

That is, in this case, if the UCI only contains SR, the UCI is discarded without transmission. If the UCI contains SR and also contains other UCI, such as HARQ-ACK and/or CSI, then, When the UCI is transmitted by the first PUSCH and the second PUSCH, the SR in the UCI can be removed, and only the UCI other than the SR in the UCI is transmitted on the first PUSCH and the second PUSCH, For example, HARQ-ACK and/or CSI.

The above (1)-(3) can be used alone or in combination. For example, (2) and (3) can be combined. When HARQ-ACK, CSI and SR are included in the UCI, it is discarded according to (3) SR, according to (2), if the first PUSCH and the second PUSCH also contain CSI, discard the CSI, and only transmit HARQ-ACK on the first PUSCH and the second PUSCH, if the first PUSCH and the second PUSCH If CSI is not included on the PUSCH, HARQ-ACK and CSI are transmitted on the first PUSCH and the second PUSCH.

In the embodiment of the present disclosure, the transmission of the UCI on the second PUSCH includes at least one of the following situations:

(1) When the UCI includes at least HARQ-ACK, the UCI is transmitted on the second PUSCH, or the HARQ-ACK is transmitted on the second PUSCH.

That is, in this case, in addition to HARQ-ACK, if the UCI also includes one or two of CSI and SR, one way is to combine all UCIs (including CSI and SR). For transmission on the second PUSCH, the UCI transmission overhead on PUSCH is relatively large, but it can prevent all UCI from being discarded. Another way is to discard one or both of CSI and SR, and only transmit HARQ- on the second PUSCH. ACK mainly considers that HARQ-ACK is more important than CSI and SR. In order to reduce the UCI transmission overhead on PUSCH, only the more important UCI can be transmitted.

(2) When the UCI includes at least CSI, if CSI transmission is also included on the second PUSCH, discard the CSI in the UCI.

In this case, if CSI transmission is also included on the second PUSCH (CSI may be A-CSI or SP-CSI), then when the UCI is transmitted on the second PUSCH, the UCI can be removed Because the CSI related information is already carried on the PUSCH itself, there is no need to carry the same type of UCI repeatedly, that is, the UCI in the UCI other than the CSI can be transmitted on the second PUSCH. For example, the UCI includes HARQ-ACK in addition to CSI, then the HARQ-ACK is transmitted on the second PUSCH.

(3) When the UCI contains at least SR, discard the SR.

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

The above (1)-(3) can be used alone or in combination. For example, (2) and (3) can be combined. When HARQ-ACK, CSI and SR are included in the UCI, it is discarded according to (3) SR, according to (2), if the second PUSCH also contains CSI, then discard the CSI, and only transmit HARQ-ACK on the second PUSCH, if the second PUSCH does not contain CSI, then transmit HARQ on the second PUSCH -ACK and CSI.

In the embodiment of the present disclosure, the PUCCH and the second PUSCH overlap in the time domain, or the PUCCH and the second PUSCH do not overlap in the time domain.

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

That is, the application scenario of the embodiment of the present disclosure is that 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. The above method can be used regardless of whether the second PUSCH and PUCCH overlap in the time domain. In particular, if the second PUSCH and PUCCH also overlap in the time domain, it means that according to the selection rule of the PUSCH transmitting UCI, the second PUSCH is not selected to transmit UCI (otherwise, if this PUSCH is selected as the PUSCH transmitting UCI, , It will not be used as the second PUSCH, but will be used as the first PUSCH). Instead, other PUSCHs are selected to transmit UCI to obtain other PUSCHs as the first PUSCH.

It should be noted that the “carrier” in the embodiments of the present disclosure can also be replaced with concepts such as serving cell, bandwidth part (Bandwidth Part, BWP), carrier on the serving cell, and BWP on the carrier on the serving cell.

It can be seen from the above that, in the embodiments of the present disclosure, when the PUCCH carrying UCI overlaps with at least one PUSCH in the time domain, if the terminal selects the first PUSCH and the second PUSCH to carry the UCI according to a predetermined rule The PUSCH overlaps in the time domain on the same carrier, and the UCI is transmitted on the first PUSCH and the second PUSCH; or, if the first PUSCH and the second PUSCH overlap in the time domain on the same carrier, when When the first PUSCH is stopped or cancelled, the UCI is transmitted on the second PUSCH. Therefore, using the solution in the embodiment of the present disclosure, when the first PUSCH carrying UCI is stopped or cancelled, it can still be guaranteed that UCI can be transmitted normally, thereby ensuring the transmission performance of UCI.

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

Step 301: When the PUCCH carrying UCI overlaps with at least one PUSCH in the time domain, if the first PUSCH and the second PUSCH selected by the terminal to carry the UCI overlap in the time domain on the same carrier, the network side device determines The UCI is transmitted on the first PUSCH and the second PUSCH; or,

When the PUCCH carrying UCI overlaps with at least one PUSCH in the time domain, if the first PUSCH and the second PUSCH selected by the terminal to carry the UCI overlap in the time domain on the same carrier, it is determined that the first PUSCH In the case of being stopped or cancelled, the network side device determines that the UCI is transmitted on the second PUSCH.

Both the first PUSCH and the second PUSCH are CG PUSCH; or,

Both the first PUSCH and the second PUSCH are PUSCHs scheduled with PDCCH.

Optionally, in the embodiment of the present disclosure, the first PUSCH may be stopped or canceled by the second PUSCH, and may also be stopped or canceled by other PUSCHs that overlap in time domain on the same carrier. When it is determined that the first PUSCH is stopped or cancelled in at least one of the following situations:

(1) When the second PUSCH is a PUSCH scheduled by PDCCH, it is determined that the first PUSCH is stopped or cancelled.

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

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

(1) When the UCI contains at least HARQ-ACK, determine to transmit the UCI on the first PUSCH and the second PUSCH, or determine to transmit on the first PUSCH and the second PUSCH The HARQ-ACK.

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

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

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

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

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

(1) When the UCI includes at least HARQ-ACK, determine to transmit the UCI on the second PUSCH, or determine to transmit the HARQ-ACK on the second PUSCH.

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

It should be noted that the “carrier” in the embodiments of the present disclosure can also be replaced with concepts such as serving cell, BWP, carrier on the serving cell, and BWP on the carrier on the serving cell.

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

It can be seen from the above that, in the embodiments of the present disclosure, when the PUCCH carrying UCI overlaps with at least one PUSCH in the time domain, if the first PUSCH and the second PUSCH selected by the terminal to carry the UCI are in the same If the time domain overlaps on the carrier, the UCI is transmitted on the first PUSCH and the second PUSCH; or, if the first PUSCH and the second PUSCH overlap in the time domain on the same carrier, when the first PUSCH and the second PUSCH overlap in the time domain When the PUSCH is stopped or cancelled, the UCI is transmitted on the second PUSCH. Therefore, using the solution in the embodiment of the present disclosure, when the first PUSCH carrying UCI is stopped or cancelled, it can still be guaranteed that UCI can be transmitted normally, thereby ensuring the transmission performance of UCI.

As shown in Figure 4, assuming that the terminal is configured with 2 CG configurations, the time domain resources of the two CG configurations overlap, the PUSCH of CG1 overlaps with a PUCCH carrying HARQ-ACK, and the priority of CG1 PUSCH and PUCCH are the same. For example, both correspond to high priority, and the timeline for transferring HARQ-ACK on PUCCH to PUSCH transmission is satisfied between PUCCH and CG1 PUSCH, then the terminal determines to transfer HARQ-ACK on PUCCH to CG1 PUSCH for transmission, instead of transmitting PUCCH , Thereby avoiding simultaneous transmission of multiple uplink channels. However, due to the overlap of time domain resources between CG1 PUSCH and CG2 PUSCH, assuming that CG1 PUSCH and CG2 PUSCH also have the same priority, for example, both are high priority, the terminal can only To transmit one of the PUSCHs, for example, according to the sequence of the PDUs (UL-SCH or TB transmitted on the PUSCH on the physical layer) sent by the terminal’s MAC layer to the terminal corresponding to the CG1 PUSCH and CG2 PUSCH, the last received The PUSCH corresponding to the received PDU has priority. Assume that the PDU arrival time of CG1 PUSCH is earlier, and the PDU arrival time of CG2 PUSCH is later, as shown in Figure 4:

On the terminal side, the terminal received the PDU corresponding to the transmission on CG1 PUSCH at an earlier time, and before receiving the PDU corresponding to the transmission on the CG2 PUSCH, it did not know that the CG2 PUSCH was to be transmitted, so it was determined If CG1 PUSCH needs to be transmitted, according to the overlapping processing rule of PUCCH and CG1 PUSCH (satisfying the timeline of multiplexing transmission), the HARQ-ACK of PUCCH is transferred to CG1 PUSCH for transmission. After the CG1 PUSCH carries the HARQ-ACK and starts transmission, since the corresponding PDU transmitted on the CG2 PUSCH is received, it is determined that the CG2 PUSCH needs to be transmitted. In order to avoid overlapping transmissions of two PUSCHs, it is necessary to stop the transmission of CG1 PUSCH, start preparing CG2 PUSCH data, and transmit CG2 PUSCH on the resources corresponding to CG2 PUSCH. When preparing CG2 PUSCH, the terminal needs to change the original PUCCH The HARQ-ACK transferred to the CG1 PUSCH for transmission is transferred to the CG2 PUSCH for transmission, so as to prevent the HARQ-ACK from being unable to be normally transmitted to the base station due to the CG1 PUSCH being stopped.

For the base station side, it cannot be determined whether CG1 PUSCH and CG2 PUSCH will be transmitted (because whether the terminal will transmit which CG PUSCH depends on whether there is corresponding data to be transmitted in the buffer on the terminal side, and the base station cannot know The buffer situation of the terminal), the base station needs to detect two PUSCHs on the resources corresponding to CG1 PUSCH and CG2 PUSCH respectively, and judge whether there is corresponding transmission by looking at the actual reception situation.

For example, when the base station tries to receive the CG1 PUSCH on the resource corresponding to the CG1 PUSCH, it judges that the HARQ-ACK on the PUCCH is transferred to the CG1 PUSCH for transmission based on the presence of the CG1 PUSCH and based on the same principle as the terminal side. Therefore, when the base station tries to receive the CG1 PUSCH, it assumes that it carries HARQ-ACK to receive it, but because the terminal side stops the transmission of CG1 PUSCH midway, the result of the base station side receiving the CG1 PUSCH is failed or judged to be discontinuous Reception (Discontinuous Reception, DTX), so that it is considered that CG1 PUSCH is not transmitted or is stopped halfway, the base station also needs to try to receive CG2 PUSCH on the resources corresponding to CG2 PUSCH.

Similarly, it is similar to the case of CG2 PUSCH on the terminal side to determine that HARQ-ACK needs to be transmitted on CG2 PUSCH. Therefore, when the base station tries to receive CG2 PUSCH, it is assumed to carry HARQ-ACK to receive, and this reception Because of the transmission behavior of the symbol terminal side, the base station finally receives the CG2 PUSCH normally and obtains the HARQ-ACK from it. In the above process, when the base station judges that the CG1 PUSCH is not received normally, because the base station does not know that the terminal side stopped the transmission of CG1 PUSCH, but there is no PDU transmission on the CG1 PUSCH at all (if this is the case, see Figure 4. There is no overlap between CG1 PUSCH and PUCCH on the terminal side, and the terminal only needs to transmit PUCCH and CG2 PUSCH on non-overlapping resources. The base station can further detect on the PUCCH resource, and the result is DTX, so as to determine the terminal The CG1 PUSCH transmission actually exists on the side, and the CG1 PUSCH is stopped or cancelled because of the overlap with the CG2 PUSCH.

It should be noted that in the foregoing embodiment, the terminal actually transmits HARQ-ACK on CG1 PUSCH and CG2 PUSCH, that is, UCI on PUCCH is transmitted on both the first PUSCH and the second PUSCH. Similarly, when the base station receives CG1 PUSCH and CG2 PUSCH, it also assumes the presence of HARQ-ACK for reception.

In Figure 4 above, only the moment when the PDU transmitted on CG2 PUSCH is received is used as the moment to stop the transmission of CG1 PUSCH, and it does not rule out that a certain buffer time is required to stop the transmission of CG1 PUSCH during the actual execution process, that is, the stop transmission of CG1 PUSCH. The time may be later than the time indicated by the dashed line 41 in FIG. 4, but the transmission of the CG1 PUSCH must be stopped before the start of the CG2 PUSCH, so as to avoid simultaneous transmission of the two.

In the above embodiment, the arrival time of the PDU corresponding to CG2 PUSCH is later than the start time of CG1 PUSCH is just an example. The arrival time of the PDU corresponding to CG2 PUSCH can also be earlier than the start time of CG1 PUSCH. Yes, at this time, CG1 PUSCH may be stopped or cancelled before transmission, so there will be no CG1 PUSCH being stopped halfway after transmitting a few symbols, so when the terminal receives the corresponding PDU transmitted on CG2 PUSCH, It only needs to stop the process of preparing for transmission information on CG1 PUSCH (such as encoding, modulation, scrambling and other pre-processing), and transfer the HARQ-ACK originally mapped to CG1 PUSCH to CG2 PUSCH, which is the same as that transmitted on CG2 PUSCH. The data is transferred together. On the base station side, because it does not know the arrival time of the PDUs corresponding to the CG1 and CG2 PUSCH on the terminal side, it always performs detection on multiple resources according to the steps in the above-mentioned embodiment.

In the above embodiment, CG1 PUSCH and CG2 PUSCH are PUSCHs that overlap each other on the same carrier, and PUSCH (CG1 PUSCH and CG2 PUSCH) and PUCCH can be on the same carrier or on different carriers. It is executed in the manner of the above-mentioned embodiment. If there are PUSCHs overlapping the PUCCH on multiple CCs at the same time, the above method is also applicable. The CG1 PUSCH in the embodiment is a PUSCH selected on multiple CCs according to the selection rule of the PUSCH carrying UCI.

In the foregoing embodiment, the CG1 PUSCH and/or CG2 PUSCH are replaced with a dynamic grant (DG) PUSCH, and the foregoing method is also applicable.

In the above-mentioned embodiment, only the PUCCH overlaps with the CG1 PUSCH, but does not overlap with the CG2 PUSCH as an example. When PUCCH overlaps with CG1 PUSCH and CG2 PUSCH, the method of the above embodiment is also applicable. When one or more of the CG PUSCH is replaced with DG PUSCH, when the PUCCH overlaps with multiple PUSCHs, the method of the above embodiment is also The same applies.

In the above embodiment, when HARQ-ACK on PUCCH is replaced with CSI, or HARQ-ACK and CSI, or CSI and SR, or HARQ-ACK, CSI, and SR, the same can be done according to The above method is executed. The difference is that in the case of including SR, according to the multiplexing transmission rules of PUCCH and PUSCH, SR will not be transferred to PUSCH, but can be directly discarded, that is, other UCIs will be transferred to PUSCH.

In the foregoing embodiment, when the foregoing channels are all assumed to be low-priority channels, the method of the foregoing embodiment is also applicable. When supporting PUCCH and PUSCH multiplexing transmission with different priorities, the aforementioned PUCCH and PUSCH may also have different priorities. When supporting PUSCHs with overlapping time domain resources on the same carrier, which PUSCH to be transmitted is determined only according to the arrival time of the PDU (that is, regardless of the priority of the first PUSCH and the second PUSCH, it is based on who is the last to receive the PDU The first PUSCH and the second PUSCH can also have different priorities.

It can be seen from the above description that in the embodiments of the present disclosure, UCI is also transmitted on the PUSCH that overlaps the PUSCH carrying the UCI of the PUCCH, or when the PUSCH carrying the UCI of the PUCCH is stopped by another PUSCH, the transmission on the other PUSCH is stopped. The UCI carried on the stopped PUSCH can be avoided to prevent the UCI carried by the PUCCH from being dropped when a PUSCH is stopped by other PUSCHs, and the transmission performance of UCI can be guaranteed.
