Description

Information transmission method and device and communication equipment

The present application claims priority from the chinese patent application entitled "a method, apparatus and communication device for information transmission", filed in the intellectual property office of the people's republic of China, application number 201910678686.2, 25, 2019, the entire contents of which are incorporated herein by reference.

Technical Field

The present disclosure relates to the field of communications technologies, and in particular, to an information transmission method, an information transmission device, and a communication device.

Background

As the demand for mobile communication services has changed, organizations such as the international telecommunications union (International Telecommunication Union, ITU) and the third generation partnership project (3rd Generation Partnership Project,3GPP) have begun to study new wireless communication systems, such as the fifth generation new radio access technology (5Generation New Radio Access Technology,5G NR).

In the current 5G NR system, uplink control information (UCI, uplink Control Information) may be transmitted using NR physical uplink control channel (PUCCH, physical Uplink Control Channel). The NR PUCCH format (format) includes 5 PUCCH formats in total of format 0, format 1, format 2, format 3, and format 4. Wherein, PUCCH formats 0 and 1 may carry UCI transmission of 1-2 bits, and PUCCH formats 2, 3 and 4 may carry UCI transmission of more than 2 bits.

UCI may include hybrid automatic repeat request Acknowledgement (Hybrid Automatic Repeat reQuest-Acknowledgement, HARQ-ACK), scheduling request (Scheduling Request, SR), periodic channel state information (Channel State Information, CSI). Wherein, the HARQ-ACK may be configured to be transmitted using PUCCH format 0 or 1 or 2 or 3 or 4, i.e., the HARQ-ACK may be transmitted using any one of the aforementioned 5 PUCCH formats, and one of a plurality of PUCCH resource sets configured in advance may be selected according to the number of bits of the HARQ-ACK, and each PUCCH resource corresponds to a range of one number of bits, that is, the PUCCH resource of the HARQ-ACK may be selected from the PUCCH resource sets configured in advance; the SR may configure transmission using PUCCH format 0 or 1, and the used PUCCH resource is configured by higher layer signaling; CSI may be configured to be transmitted using UCCH format 2 or 3 or 4, and the PUCCH resources used are configured by higher layer signaling.

In 5G NR, release 15 (Rel-16) only supports at most one PUCCH for carrying HARQ-ACK for transmission in one slot, so that only one PUCCH for carrying HARQ-ACK may overlap with the PUCCH for carrying SR and/or CSI in the time domain. While release 16 (Rel-16) supports the transmission of multiple time division multiplexed (Time Division Multiplexing, TDM) PUCCHs in one slot for carrying HARQ-ACKs, there is a problem in that there is no specific multiplexing transmission method at present when there is overlap in the time domain between multiple PUCCHs carrying multiple HARQ-ACKs in one slot and PUCCHs for carrying SRs and/or CSI.

It can be seen that in case Rel-16 supports transmission of multiple time division multiplexed PUCCHs in one slot, each carrying a different HARQ-ACK, there may be an overlap (e.g. at least one symbol overlap) in the time domain between the PUCCHs of multiple TDM for carrying multiple HARQ-ACKs and the PUCCHs for carrying SR and/or CSI, and how such overlapping transmission is handled has not yet been explicitly done. Therefore, resolving the collision of PUCCH resources of multiple UCI in the time domain is a current problem that needs to be resolved.

Disclosure of Invention

The embodiment of the application provides an information transmission method, an information transmission device and communication equipment, which are used for solving the technical problem that a plurality of PUCCHs carrying a plurality of HARQ-ACKs in one time slot are overlapped with PUCCHs carrying other types of UCIs in time domain, so as to provide a transmission resource multiplexing transmission scheme of the plurality of HARQ-ACKs in one time slot and the UCIs of other types in time domain.

On the terminal side, the embodiment of the application provides an information transmission method, which comprises the following steps:

when a first PUCCH carrying a first UCI and a plurality of second PUCCHs carrying HARQ-ACKs which are not overlapped in the time domain are overlapped in the time domain, discarding the first UCI by the terminal equipment;

or,

when a first PUCCH carrying a first UCI and a second PUCCH carrying a first HARQ-ACK are overlapped in a time domain, if a third PUCCH carrying the first HARQ-ACK and the first UCI are determined to be overlapped in the time domain, discarding the first UCI by the terminal equipment;

wherein the first UCI is another type of UCI different from HARQ-ACK; or when the first UCI includes HARQ-ACK, the priority of the HARQ-ACK included in the first UCI is lower than the priority of the HARQ-ACK carried on the second PUCCH.

By the method, when a plurality of PUCCHs carrying a plurality of HARQ-ACKs which are not overlapped in a time slot are overlapped with PUCCHs of other types of UCIs (namely, first UCIs) in the time slot, the problem of time-domain resource overlapping can be solved by discarding the first UCIs, namely, the situation that the HARQ-ACKs which are not overlapped in the time slot are overlapped with other types of UCIs in the time slot and need to be transmitted in a multiplexing way can be avoided, and therefore, the effective and timely transmission of the HARQ-ACKs can be ensured.

The terminal device is wirelessly connected to the network device, and data transmission can be performed between the terminal device and the network device, for example, data transmitted from the network device to the terminal device is referred to as downlink transmission, and data transmitted from the terminal device to the network device is referred to as uplink transmission.

It should be noted that, the scenario shown in fig. 1 should not limit the application scenario in the embodiment of the present application, and in practical application, the scenario may include a plurality of network devices and a plurality of terminal devices. For example, one terminal device may perform data transmission with only one network device, or may perform data transmission with a plurality of network devices, or one network device may perform data transmission with one terminal device, or may perform data transmission with a plurality of terminal devices, that is, the number of terminal devices and network devices in fig. 1 is merely an example, and in practical application, one network device may provide services for a plurality of terminal devices, which is not limited in particular in this embodiment of the present application.

In connection with the application scenario shown in fig. 1, before the description of the multiplexing transmission scheme of UCI in the NR R16 system, the description of the multiplexing transmission scheme in the NR R15 system is first described below.

In the NR R15 system, when the PUCCH carrying CSI/SR overlaps with one PUCCH carrying HARQ-ACK, multiplexing transmission is performed according to the following method.

1) When the PUCCH carrying the SR overlaps with the PUCCH carrying the HARQ-ACK and the PUCCH carrying the HARQ-ACK uses PUCCH format0 (the PUCCH carrying the SR may use format0 or format 1), the transmission SR and the HARQ-ACK are multiplexed on the PUCCH resource of the HARQ-ACK, that is, the HARQ-ACK is transmitted by the HARQ-ACK corresponding to different Cyclic Shift (CS) when the PUCCH resource usage of the HARQ-ACK corresponds to the presence of positive SR and negative SR, implying whether the SR is positive (positive) or negative (negative).

2) When the PUCCH carrying the SR overlaps with the PUCCH carrying the HARQ-ACK and the PUCCH carrying the SR uses format0 (PUCCH format 0), the PUCCH carrying the HARQ-ACK uses format1 (PUCCH format 1), the (drop) SR is discarded, i.e. no multiplexing transmission is performed at this time.

3) When the PUCCH carrying SR overlaps with the PUCCH carrying HARQ-ACK, and the PUCCH carrying SR uses format1, and the PUCCH carrying HARQ-ACK uses format1, when there is a positive SR, HARQ-ACK is transmitted on the PUCCH resource of SR, so that the simultaneous SR transmission is implicitly expressed by transmitting HARQ-ACK using the PUCCH resource corresponding to SR, otherwise (i.e., negative SR), HARQ-ACK is transmitted on the PUCCH resource of HARQ-ACK.

4) When the PUCCH carrying the SR overlaps with the PUCCH carrying the HARQ-ACK and the PUCCH carrying the HARQ-ACK uses format 2 or 3 or 4 (the PUCCH carrying the SR may use format0 or format 1), one PUCCH resource set is determined according to the total number of bits of the SR and the HARQ-ACK, and one PUCCH resource is determined in the determined one PUCCH resource set according to the PUCCH resource indication field in the DCI corresponding to the HARQ-ACK, for transmitting the SR and the HARQ-ACK simultaneously, where the SR is X bits, indicating the SR state (which is positive or both positive) of the X SRs overlapping with the HARQ-ACK, that is, whether the SR is positive or negative, the X-bit SR is always transmitted, so as to avoid the change of the number of UCI bits transmitted on the PUCCH resource of the HARQ-ACK due to the SR state.

5) When the PUCCH carrying SPS HARQ-ACK (i.e. HARQ-ACK corresponding to Semi-persistent scheduling (Semi-static Scheduling, SPS) physical downlink shared channel (Physical Downlink Shared Channe, PDSCH)) overlaps with the PUCCH carrying CSI, the SPS HARQ-ACK is transferred to PUCCH resources corresponding to CSI for multiplexing transmission with CSI.

6) When the PUCCH carrying dynamic HARQ-ACK (namely the HARQ-ACK corresponding to the PDSCH scheduled by the corresponding downlink control information (Downlink Control Information, DCI) or indicating DCI released by the downlink SPS PDSCH) overlaps with the PUCCH carrying CSI, selecting one PUCCH resource set from a plurality of PUCCH resource sets according to the total bit number of the HARQ-ACK and the CSI, and determining one PUCCH resource from the selected one PUCCH resource set according to the PUCCH resource indication field in the DCI corresponding to the HARQ-ACK for simultaneously carrying the HARQ-ACK and the CSI; the re-determined PUCCH resource may be the same as or different from the PUCCH resource carrying the HARQ-ACK (i.e. a new PUCCH resource if different).

When a plurality of PUCCHs exist in one time slot and overlap exists among the PUCCHs, assuming that the PUCCHs in one time slot form a set Q, determining an uplink channel with the earliest starting time in the set Q as a channel A, and determining a channel set X overlapping with the channel A; and obtaining a channel resource for multiplexing transmission for UCI on the channel A and the channel X according to the multiplexing transmission rule, replacing the channel A and the channel X in the set Q by the channel resource for multiplexing transmission, continuing the steps to determine the channel A and the channel X in the new set Q, and the like until obtaining a plurality of PUCCHs which are not overlapped in time domain.

In Rel-15, there is only a case where PUCCH resources of one HARQ-ACK overlap with PUCCH resources of CSI/SR, and there is no case where PUCCH for carrying HARQ-ACK overlap with PUCCH resources of one for carrying SR/CSI as in multiple time division multiplexing in Rel-16. Therefore, in Rel-16, a plurality of time division multiplexed PUCCHs for carrying HARQ-ACKs are supported for transmission in one slot, and there is an overlap between a plurality of PUCCHs for carrying HARQ-ACKs and PUCCHs for carrying SR/CSI, and for this case, there is no specific multiplexing transmission method, and if the multiplexing transmission rule is simply reused directly, it may result in that a plurality of HARQ-ACKs originally transmitted in TDM need to be multiplexed on the same PUCCH for transmission, which affects the transmission delay and transmission performance of HARQ-ACKs. For example, if the transmission time or starting position of the PUCCH resource for multiplexing transmission of a plurality of HARQ-ACKs is longer than the transmission time or starting position of the PUCCH resource originally carrying HARQ-ACKs is delayed, the transmission delay will be increased compared with the original HARQ-ACK transmission; for example, multiplexing PUCCH resources for transmitting multiple HARQ-ACKs may reduce transmission performance of the original HARQ-ACK if a transmission rate is higher than that of PUCCH resources originally carrying HARQ-ACKs due to more UCI. The information transmission scheme provided by the embodiment of the application solves the technical problem that the PUCCH carrying a plurality of HARQ-ACKs in one time slot overlaps with the PUCCH carrying other types of UCI in time domain, so as to provide a multiplexing transmission scheme of a plurality of HARQ-ACKs in one time slot and other types of UCI.

The following describes the technical scheme provided by the embodiment of the application with reference to the accompanying drawings.

As shown in fig. 2, an information transmission system provided in an embodiment of the present application includes a terminal device 21 and a network device 22. The terminal device 21 is, for example, the terminal device described above, and the network device 22 is, for example, the network device described above.

In one embodiment, the terminal device 21 is configured to discard the first UCI when a first PUCCH carrying the first UCI overlaps with a plurality of second PUCCHs carrying HARQ-ACKs that do not overlap in time domain. Correspondingly, the network device 22 is configured to determine that the first UCI is discarded when the first PUCCH carrying the first UCI overlaps with a plurality of second PUCCHs carrying HARQ-ACKs that do not overlap in time domain.

Wherein the first UCI is another type of UCI than HARQ-ACK, for example, the first UCI is SR, or is CSI, or contains both CSI and SR, i.e., the first UCI is CSI and/or SR.

In another possibility, the first UCI is HARQ-ACK, and when the first UCI is HARQ-ACK, the priority of the HARQ-ACK corresponding to the first UCI is lower than the priority of the HARQ-ACK carried on the second PUCCH. For example, the HARQ-ACK in the first UCI corresponds to a first traffic type, the HARQ-ACK carried on the second PUCCH corresponds to a second traffic type, wherein the priority of the first traffic type is lower than the priority of the second traffic type, further for example, the HARQ-ACK in the first UCI corresponds to enhanced mobile broadband (Enhance Mobile Broadband, eMBB) traffic, the HARQ-ACK carried on the second PUCCH corresponds to very reliable low latency communication (Ultra Reliable Low Latency Communications, URLLC) traffic, further for example, the HARQ-ACK in the first UCI corresponds to a first priority level, the HARQ-ACK carried on the second PUCCH corresponds to a second priority level, wherein the first priority level is less than or equal to the second priority level, and so on.

The multiple second PUCCHs carrying HARQ-ACKs that do not overlap in time domain are located in one time slot, that is, the technical scheme of the present application may be applied to an application scenario supporting transmission of multiple HARQ-ACKs in a time division multiplexing manner in one time slot, and there is a situation that multiple second PUCCHs carrying the multiple HARQ-ACKs overlap with the first PUCCH carrying the first UCI in time domain. That is, in the embodiment of the present application, the plurality of second PUCCHs and the first PUCCH are all located in the same slot, and the plurality of second PUCCHs are all non-overlapping in the time domain, and the plurality of second PUCCHs are all overlapping with the first PUCCH in the time domain.

As such, when there is overlap in time domain between PUCCH resources of a plurality of HARQ-ACKs within one slot and PUCCH resources of the first UCI, the terminal device 21 may discard the first UCI. Accordingly, the network device 22 may also determine that the first UCI is discarded based on the same understanding as the terminal device 21.

By the scheme, the terminal side and the network side can be ensured to multiplex and transmit a plurality of HARQ-ACKs originally transmitted in TDM on the same PUCCH channel by discarding some UCIs under the condition that transmission resources of different UCIs are overlapped in time domain, so that the technical problem of time domain overlapping is solved, the transmission time delay of the HARQ-ACKs can be further reduced, the transmission performance of the HARQ-ACKs is improved, and the HARQ-ACKs can be timely and effectively transmitted.

In another embodiment, the terminal device 21 is configured to discard the first UCI when it is determined that the first PUCCH carrying the first UCI overlaps with the second PUCCH carrying the first HARQ-ACK in the time domain and the third PUCCH carrying the first HARQ-ACK overlaps with the fourth PUCCH carrying the second HARQ-ACK in the time domain; correspondingly, the network device 22 is configured to determine, when a first PUCCH carrying a first UCI overlaps with a second PUCCH carrying a first HARQ-ACK in a time domain, that the first UCI is discarded if it is determined that a third PUCCH carrying the first HARQ-ACK and the first UCI overlap with a fourth PUCCH carrying a second HARQ-ACK in the time domain.

Wherein the first HARQ-ACK and the second HARQ-ACK may be transmitted within one slot, i.e., a second PUCCH for carrying the first HARQ-ACK and a fourth PUCCH for carrying the second PUCCH are located within one slot and do not overlap in time domain. And, the first PUCCH for carrying the first UCI is also located in the slot, in other words, the first PUCCH, the second PUCCH, and the fourth PUCCH in the embodiment of the present application are all located in the same slot, and the second PUCCH and the fourth PUCCH do not overlap in time domain.

Thus, when there is overlap in the time domain between the PUCCH resource of one HARQ-ACK (e.g. the first HARQ-ACK) and the PUCCH resource of one other type UCI (e.g. the first UCI) in one slot, if, for example, the PUCCH resource (e.g. the third PUCCH) for carrying the first HARQ-ACK and the first UCI simultaneously determined according to the multiplexing transmission rule overlaps in the time domain with the PUCCH resource (e.g. the fourth PUCCH) for carrying the other HARQ-ACK (e.g. the second HARQ-ACK), the terminal device 21 may discard the first UCI. Accordingly, the network device 22 may also determine that the first UCI is discarded based on the same understanding as the terminal device 21.

Through the scheme, the terminal side and the network side can be guaranteed to be consistent in understanding the discarding of the UCI under the condition that the transmission resources of different UCIs are overlapped in the time domain, so that the technical problem that the transmission resources of the UCI are overlapped in the time domain is solved.

The following describes the information transmission scheme in the embodiment of the present application in detail with reference to the accompanying drawings.

Referring to fig. 3, a flow chart corresponding to an information transmission method provided in the embodiment of the present application is shown, where the method may be executed by a terminal device, and specifically includes the following steps.

Step 31: the terminal equipment determines that a first PUCCH carrying a first UCI and a plurality of second PUCCHs carrying HARQ-ACKs which are not overlapped in the time domain are overlapped in the time domain; or the terminal equipment determines that a first PUCCH carrying a first UCI and a second PUCCH carrying a first HARQ-ACK overlap in a time domain, and determines that a third PUCCH carrying the first HARQ-ACK and the first UCI simultaneously overlap in the time domain with a fourth PUCCH carrying the second HARQ-ACK.

Step 32: the terminal device discards the first UCI.

That is, when the two overlapping situations exist, the terminal device may directly discard the first UCI to ensure effective transmission of HARQ-ACK as much as possible, and improve validity and timeliness of UCI transmission such as HARQ-ACK.

In the embodiment of the present application, there are various cases where the plurality of second PUCCHs overlap with the first PUCCH in the time domain, and the following description will be given.

In the first case, the second PUCCH and the first PUCCH are completely overlapped in the time domain for each. As shown in fig. 4a, a schematic diagram of overlapping, in time domain, a first PUCCH carrying a first UCI and multiple PUCCHs carrying HARQ-ACKs provided in an embodiment of the present application. Wherein, for example, the PUCCH resource of the first UCI is PUCCH-0, occupying 8 symbols; the PUCCH resource of the HARQ-ACK-1 in the two HARQ-ACKs is PUCCH-1, occupies 2 symbols, the PUCCH resource of the HARQ-ACK-2 is PUCCH-2, and occupies two symbols. As can be seen from fig. 4a, the PUCCH resource (PUCCH-0) of the first UCI completely overlaps with the PUCCH resources (PUCCH-1, PUCCH-2) of both the second HARQ-ACKs (i.e. HARQ-ACK-1 and HARQ-ACK-2).

In the second case, the second PUCCH is partially overlapped with the first PUCCH in the time domain for each second PUCCH. As shown in fig. 4b, another schematic diagram of overlapping, in time domain, a first PUCCH carrying a first UCI and a plurality of second PUCCHs provided in an embodiment of the present application. For example, the PUCCH resource of the first UCI is PUCCH-0, occupying 8 symbols; the PUCCH resource of the HARQ-ACK-1 in the two HARQ-ACKs is PUCCH-1, occupies 2 symbols, the PUCCH resource of the HARQ-ACK-2 is PUCCH-2, and occupies 2 symbols. As can be seen from fig. 4b, the PUCCH resource (PUCCH-0) of the first UCI partially overlaps with the PUCCH resources (PUCCH-1, PUCCH-2) of both HARQ-ACKs.

In the third case, the PUCCH of the partial HARQ-ACK is overlapped with the PUCCH resource of the first UCI entirely, and the PUCCH of the partial HARQ-ACK is overlapped with the PUCCH resource of the first UCI partially. As shown in fig. 4c, another schematic diagram of overlapping, in time domain, a first PUCCH carrying a first UCI and multiple second PUCCHs provided in an embodiment of the present application is shown. If the PUCCH resource of the first UCI is PUCCH-0, 8 symbols are occupied; the PUCCH resource of one HARQ-ACK-1 in the two HARQ-ACKs is PUCCH-1, occupies 2 symbols, the PUCCH resource of the HARQ-ACK-2 is PUCCH-2, and occupies 2 symbols. As can be seen from fig. 4c, the PUCCH resource (PUCCH-0) of the first UCI partially overlaps with the PUCCH resource (PUCCH-1) of one HARQ-ACK (i.e. HARQ-ACK-1) and completely overlaps with the PUCCH resource (PUCCH-2) of the other HARQ-ACK (i.e. HARQ-ACK-2).

As mentioned above, in the embodiment of the present application, the first UCI may be CSI and/or SR, or the first UCI may be HARQ-ACK with a lower priority than HARQ-ACK carried by the second PUCCH, and the description below may be given for the first UCI separately for different types of UCI.

Example one

In example one, that is, in a case where a first PUCCH carrying a first UCI overlaps with a plurality of second PUCCHs carrying HARQ-ACKs that do not overlap in the time domain, for example, two second PUCCHs carrying HARQ-ACKs overlap with one PUCCH resource carrying CSI, for example, as shown in fig. 5 a-5 b.

In this embodiment of the present application, as described above, the plurality of second PUCCHs for carrying the plurality of HARQ-ACKs are located in one slot and do not overlap each other, for example, are located in different sub-slots in one slot respectively, the first PUCCH for carrying CSI is located in the same slot as the plurality of second PUCCHs for carrying the plurality of HARQ-ACKs, and the plurality of second PUCCHs overlap with the first PUCCH in time domain, i.e., each second PUCCH overlaps with the first PUCCH in time domain. The sub-time slots are time units with fixed symbol numbers in one time slot which is appointed or configured, wherein the sequence of the sub-time slots in one time slot, the position of each sub-time slot and the symbol numbers contained in the sub-time slots are appointed or configured in advance. And the number of symbols contained in different sub-slots in one slot is the same or different. That is, the number of symbols included in each sub-slot included in the same slot may be the same, for example, 7 or 2 symbols, and of course, the number of symbols included in each sub-slot may be different, for example, the first sub-slot includes 4 symbols, and the second sub-slot includes 3 symbols, but the specific number of symbols may be determined by pre-provisioning or configuration.

Referring to fig. 5a to 5b, in fig. 5a and 5b, taking the first UCI as CSI as an example, a case where there is overlap in time domain between PUCCH resources for carrying two HARQ-ACKs and PUCCH resources for carrying CSI is illustrated. In fig. 5a, both PUCCHs for carrying HARQ-ACK-1 and HARQ-ACK-2 overlap partially with PUCCHs for carrying CSI; in fig. 5b, the PUCCH for carrying HARQ-ACK-1 overlaps with the PUCCH for carrying CSI in its entirety, and the PUCCH for carrying HARQ-ACK-2 overlaps with the PUCCH for carrying CSI in its part.

That is, when the first PUCCH carrying CSI overlaps with the plurality of second PUCCHs carrying the plurality of HARQ-ACKs, which do not overlap in the time domain, in both the time domain, the terminal device may discard CSI directly, as shown in fig. 6, so that overlapping of CSI and HARQ-ACKs may be avoided. After the CSI is discarded, the terminal device may transmit the HARQ-ACK on the PUCCH resource corresponding to the HARQ-ACK, that is, may independently transmit the corresponding HARQ-ACK on the PUCCH resource originally configured for each HARQ-ACK, that is, may separately transmit the corresponding one HARQ-ACK on each second PUCCH, thereby ensuring that the HARQ-ACK may be effectively and timely transmitted.

In this embodiment of the present application, when the first PUCCH carrying CSI overlaps with the second PUCCHs carrying acknowledgement HARQ-ACKs that do not overlap in the time domain, the terminal device may further determine whether a preset discard condition is met, and if the preset discard condition is met, the terminal device discards the first UCI, and if the preset discard condition is not met, the terminal device does not discard the CSI, that is, may use the preset discard condition as a basis for determining whether to discard the CSI finally.

For the convenience of understanding of those skilled in the art, some possible cases of preset discard conditions are described below with reference to the accompanying drawings, i.e., the terminal device may determine whether to discard CSI in the following manner.

First determination method

When the first PUCCH carrying the CSI and the second PUCCH carrying the HARQ-ACK which are not overlapped in the time domain are overlapped in the time domain, if the fact that the plurality of HARQ-ACKs need to be transmitted on the same PUCCH at the same time is determined, the terminal equipment discards the CSI.

In the implementation process, an existing multiplexing transmission rule may be used to determine whether multiple HARQ-ACKs need to be transmitted simultaneously on the same PUCCH. Specifically:

in example 1, based on the situation of fig. 5a, assuming that the PUCCH of the first HARQ-ACK (i.e. HARQ-ACK-1) uses PUCCH format 2 or 3 or 4, according to the existing multiplexing transmission rule of multiple overlapping channels, determining a channel a with earliest starting time, i.e. PUCCH of HARQ-ACK-1, determining that the channel set X overlapping with channel a is the PUCCH carrying CSI, determining a PUCCH resource set according to the total number of bits of HARQ-ACK-1 and CSI according to the multiplexing rule, and determining a PUCCH resource in the determined PUCCH resource set according to the PUCCH resource indication field in DCI corresponding to HARQ-ACK-1, for carrying HARQ-ACK-1 and CSI simultaneous transmission. Continuing to replace resource a and resource X with this resource, the above multiplexing transmission rule is further repeated for the overlapping channel.

1) If the determined multiplexing resource overlaps with another HARQ-ACK (e.g., HARQ-ACK-2 in fig. 5 a) in the time domain, as shown in fig. 7a, according to the multiplexing transmission rule, at this time, it is determined that the resource a is a PUCCH resource carrying the first HARQ-ACK (i.e., HARQ-ACK-1) and the CSI, and it is determined that the resource X overlapping with the resource a is a PUCCH of the second HARQ-ACK (i.e., HARQ-ACK-2), according to the multiplexing transmission rule, it is necessary to find one PUCCH resource for simultaneously transmitting the first HARQ-ACK, the CSI and the second HARQ-ACK according to the total number of bits of the first HARQ-ACK, the CSI and the second HARQ-ACK (the step of determining this resource is the same as above, and one PUCCH resource is determined according to the total number of bits of the PUCCH resource indication field in the DCI corresponding to the HARQ-ACK), that is, it is satisfied that the HARQ-ACKs of the plurality of TDM are determined to be transmitted on the same PUCCH according to the multiplexing transmission rule, and the CSI is not present after the drcsi, and the two HARQ-ACKs can be transmitted independently on the respective resources.

2) If the determined multiplexing resource does not overlap with the HARQ-ACK-2 in the time domain, as shown in FIG. 7b, the HARQ-ACK-1 and the CSI are simultaneously transmitted on this multiplexing resource, and the HARQ-ACK-2 is directly transmitted on the PUCCH of the HARQ-ACK-2.

Example 2, based on the situation of fig. 5a, assuming that HARQ-ACK carried by PUCCH of HARQ-ACK-1 is HARQ-ACK of SPS PDSCH (abbreviated as SPS HARQ-ACK, SPS AN), using PUCCH format 0 or 1, determining, according to the existing multiplexing transmission rule of multiple overlapping channels, first a channel a with earliest starting time, that is, PUCCH for carrying HARQ-ACK, and determining that channel set X overlapping channel a is PUCCH for carrying CSI, HARQ-ACK-1 may be transferred to CSI resource for simultaneous transmission with CSI according to the multiplexing rule, that is, determining that resource for simultaneous transmission carrying HARQ-ACK-1 and CSI is PUCCH for CSI; since this resource overlaps with another HARQ-ACK (i.e., HARQ-ACK-2) resource, it is determined according to the multiplexing rule that multiple TDM HARQ-ACKs need to be transmitted on the same PUCCH (e.g., if the second HARQ-ACK PUCCH uses PUCCH format 2 or 3 or 4, one PUCCH resource needs to be found for simultaneously transmitting the first HARQ-ACK, CSI and the second HARQ-ACK according to the total number of bits of the first HARQ-ACK, CSI and the second HARQ-ACK, as shown in fig. 7c, and if the second HARQ-ACK is SPS HARQ-ACK, and also needs to be transferred to the CSI resource for transmission, as shown in fig. 7 d), the drop CSI is determined because there is no overlap of CSI and HARQ-ACK after the drop CSI, and the two HARQ-ACKs can be independently transmitted on the respective resources.

Based on the situation of fig. 5b, in accordance with the multiplexing transmission rule, it is determined that the channel a with the earliest starting position is the PUCCH for carrying CSI, and that the set of channels X overlapping with the channel a is the PUCCH resources for carrying HARQ-ACK-1 and HARQ-ACK-2, then one resource needs to be determined for transmitting HARQ-ACK-1, HARQ-ACK-2 and CSI simultaneously, i.e. it is satisfied that HARQ-ACKs for determining multiple TDM according to the multiplexing transmission rule need to be transmitted on the same PUCCH (for example, the multiplexing transmission rule is specifically that, when one HARQ-ACK uses PUCCH format 2 or 3 or 4, then one PUCCH resource needs to be found for transmitting HARQ-ACK-1, CSI and HARQ-ACK-2 simultaneously according to the total number of bits of HARQ-ACK-1, CSI and HARQ-ACK-2, as shown in fig. 7e, when two HARQ-ACKs are both HARQ-ACKs with PUCCH format 0 or 1, for example, then it is determined that both HARQ-ACKs are transferred to CSI resources, as shown in fig. 7 d), then drop is not available for transmitting HARQ-ACKs on the respective HARQ-ACK resources after the CSI.

Second determination mode

When the first PUCCH carrying CSI overlaps with the plurality of second PUCCHs carrying HARQ-ACKs that do not overlap in time domain, if it is determined that the PUCCHs carrying both the first HARQ-ACK and the CSI overlap with the PUCCH carrying the second HARQ-ACK in time domain, the terminal device discards the CSI, as shown in fig. 8.

The first HARQ-ACK and the second HARQ-ACK are HARQ-ACKs respectively carried on two different second PUCCHs in the plurality of second PUCCHs.

In example 1, based on the situation of fig. 5a, assuming that PUCCH of HARQ-ACK-1 uses PUCCH format 2 or 3 or 4, according to the existing multiplexing transmission rule of overlapping multiple channels, first determining a channel a with earliest starting time, that is, PUCCH of HARQ-ACK-1, determining that a channel set X overlapping the channel is PUCCH carrying CSI, determining a PUCCH resource set according to the multiplexing transmission rule according to the total number of bits of HARQ-ACK-1 and CSI, and determining a PUCCH resource in the determined PUCCH resource set according to the PUCCH resource indication field in DCI corresponding to HARQ-ACK-1, for carrying HARQ-ACK-1 and CSI for simultaneous transmission.

1) If the determined multiplexing resource overlaps with the HARQ-ACK-2 in the time domain, as shown in fig. 9a, that is, it is satisfied that the PUCCH resource carrying a certain HARQ-ACK and CSI determined according to the multiplexing transmission rule overlaps with another PUCCH resource carrying a HARQ-ACK in the time domain, the drop CSI, because there is no overlap of CSI and HARQ-ACK after the drop CSI, the two HARQ-ACKs may be independently transmitted on the respective resources.

2) If there is no overlap in the time domain between the determined multiplexing resource and the HARQ-ACK-2, as shown in FIG. 9b, the HARQ-ACK-1 and the CSI are simultaneously transmitted on this resource, and the HARQ-ACK-2 is directly transmitted on the PUCCH of the HARQ-ACK-2.

Example 2, based on the case of fig. 5a, assuming that the HARQ-ACK carried by the PUCCH carrying HARQ-ACK-1 is the HARQ-ACK of the SPS PDSCH (abbreviated as SPS HARQ-ACK), using PUCCH format 0 or 1, determining, according to the existing multiplexing transmission rule for overlapping multiple channels, first, a channel a with earliest starting time, i.e., the PUCCH of HARQ-ACK-1, and determining that the channel set X overlapping the channel is the PUCCH carrying CSI, then, according to the multiplexing rule, HARQ-ACK-1 may be transferred to the PUCCH carrying CSI for simultaneous transmission with CSI on the CSI resource, i.e., determining that the resource for simultaneous transmission carrying HARQ-ACK-1 and CSI is the PUCCH of CSI; since this resource overlaps with another HARQ-ACK (HARQ-ACK-2) resource, the CSI is drop, and since there is no overlap of CSI and HARQ-ACK after the drop CSI, the two HARQ-ACKs can be transmitted independently on the respective resources, as shown in fig. 9 c.

Third determination mode

When the first PUCCH carrying CSI overlaps with the plurality of second PUCCHs carrying HARQ-ACKs that do not overlap in the time domain, if the starting position of the first PUCCH carrying CSI is earliest, as shown in fig. 5b, the terminal device discards the CSI.

Fourth determination mode

When the first PUCCH carrying CSI is overlapped with the plurality of second PUCCHs carrying HARQ-ACKs which are not overlapped in the time domain, if the HARQ-ACKs carried by the plurality of second PUCCHs are all HARQ-ACKs of the SPS PDSCH (i.e. no corresponding PDCCH can obtain PUCCH resources with relatively large carrying capacity through a PUCCH resource indication field in the PDCCH), or the HARQ-ACKs carried by the plurality of second PUCCHs are all HARQ-ACKs transmitted without using PUCCH formats 2 or 3 or 4, the terminal device discards the CSI.

Assuming that both HARQ-ACK-1 and HARQ-ACK-2 are SPS HARQ-ACKs, as in the case of fig. 5a or fig. 5b, drop CSI can be determined directly (since in this case, no PUCCH format 2 or 3 or 4 resources corresponding to one HARQ-ACK can be provided for simultaneous transmission of HARQ-ACK and CSI, HARQ-ACKs can only be transmitted on the resources of CSI, resulting in multiplexed transmission of multiple HARQ-ACKs), there is no overlap of CSI and HARQ-ACK after drop CSI, and two HARQ-ACKs can be transmitted independently on the respective resources. Assuming that the first HARQ-ACK (i.e. HARQ-ACK-1, of course, also may be the second HARQ-ACK) is feedback information of the PDSCH scheduled by the corresponding PDCCH or feedback information of the PDCCH indicating the release of the downlink SPS resources, it is explained that the first HARQ-ACK has the corresponding DCI (i.e. PDCCH described above), so that there is a possibility that a multiplexed transmission resource for simultaneously transmitting the HARQ-ACK and the CSI may be determined according to the PUCCH resource indication field in the DCI and the total number of bits of the HARQ-ACK and the CSI, and then the implementation in example 1 (for the case of fig. 5 a) and example 3 (for the case of fig. 5 b) needs to be performed at this time.

The four possible preset dropping conditions are described in the four determining manners, that is, the terminal device may finally select to drop the first UCI (for example, CSI) in the four determining manners described above, so as to avoid transmission collision between the HARQ-ACK and the first UCI in the dropping manner, thereby ensuring that each HARQ-ACK can independently perform information transmission on the PUCCH resources configured respectively, ensuring the validity of HARQ-ACK transmission as much as possible, and improving the reliability of the communication system. Meanwhile, for the case that the first UCI is not discarded, a multiplexing transmission manner among a plurality of UCI is also provided.

In the first example, the first UCI is replaced by the CSI, and the first UCI is the HARQ-ACK with a priority lower than that of the HARQ-ACK carried on the second PUCCH, and the specific process may be understood with reference to the description of using the first UCI as the CSI, where the scenario is assumed that the first UCI is transmitted using one of PUCCH formats 2, 3 or 4 or that the number of bits of the first UCI is greater than 2 bits, and is not repeated for brevity of line. The terminal device can avoid transmission conflict among a plurality of HARQ-ACKs with different priority levels in a discarding mode, so that the HARQ-ACKs transmitted on the second PUCCH with higher priority levels can be ensured to independently transmit information on the PUCCH resources configured respectively, and the effectiveness of the HARQ-ACK transmission is ensured.

Example two

In example two, that is, in the case that a first PUCCH carrying a first UCI overlaps with a plurality of second PUCCHs carrying HARQ-ACKs that do not overlap in the time domain, for example, two second PUCCHs carrying HARQ-ACKs overlap with PUCCH resources carrying an SR, for example, as shown in fig. 10 a-10 b.

In this embodiment of the present application, as described above, the plurality of second PUCCHs for carrying the plurality of HARQ-ACKs are located in one slot and do not overlap each other, for example, are located in different sub-slots in one slot respectively, the first PUCCH for carrying the SR is located in the same slot as the plurality of second PUCCHs for carrying the plurality of HARQ-ACKs, and the plurality of second PUCCHs overlap the first PUCCH in time domain, i.e., each second PUCCH overlaps the first PUCCH in time domain. The sub-time slots are time units with fixed symbol numbers in one time slot which is appointed or configured, wherein the sequence of the sub-time slots in one time slot, the position of each sub-time slot and the symbol numbers contained in the sub-time slots are appointed or configured in advance. And the number of symbols contained in different sub-slots in one slot is the same or different. That is, the number of symbols included in each sub-slot included in the same slot may be the same, for example, 7 or 2 symbols, and of course, the number of symbols included in each sub-slot may be different, for example, the first sub-slot includes 4 symbols, and the second sub-slot includes 3 symbols, but the specific number of symbols may be determined by pre-provisioning or configuration.

Referring to fig. 10a to 10b, in fig. 10a and 10b, taking the first UCI as an SR as an example, a case where there is overlap in time domain between PUCCH resources for carrying two HARQ-ACKs and PUCCH resources for carrying SRs is illustrated. In fig. 10a, two PUCCHs for carrying HARQ-ACK-1 and HARQ-ACK-2 are each partially overlapped with a PUCCH for carrying SR; in fig. 10b, the PUCCH for carrying HARQ-ACK-1 overlaps with the PUCCH for carrying SR in its entirety, and the PUCCH for carrying HARQ-ACK-2 overlaps with the PUCCH for carrying SR in its part.

That is, when the first PUCCH carrying the SR overlaps with the plurality of second PUCCHs carrying the plurality of HARQ-ACKs, which do not overlap in the time domain, in both the time domain, the terminal device may directly discard the SR, as shown in fig. 11, so that the overlapping of the SR and the HARQ-ACKs may be avoided. After discarding the SR, the terminal device may transmit the HARQ-ACK on the PUCCH resource corresponding to the HARQ-ACK, that is, may independently transmit the corresponding HARQ-ACK on the PUCCH resource originally configured for each HARQ-ACK, that is, may separately transmit the corresponding one HARQ-ACK on each second PUCCH, thereby ensuring that the HARQ-ACK can be effectively and timely transmitted.

In this embodiment of the present application, when the first PUCCH carrying the SR overlaps with the second PUCCHs carrying the acknowledgement HARQ-ACKs that do not overlap in the time domain, the terminal device may further determine whether a preset discard condition is satisfied, and if the preset discard condition is satisfied, the terminal device discards the SR, and if the preset discard condition is not satisfied, the terminal device does not discard the SR, that is, may use the preset discard condition as a basis for determining whether to discard the SR finally.

For the convenience of understanding of those skilled in the art, some possible cases of preset discard conditions are described below with reference to the accompanying drawings, i.e., the terminal device may determine whether to discard the SR in the following manner of determination.

First determination method

When the first PUCCH carrying the SR overlaps with the second PUCCHs carrying the HARQ-ACKs, which do not overlap in the time domain, if it is determined that the plurality of HARQ-ACKs need to be transmitted simultaneously on the same PUCCH, the terminal device discards the SR.

example 1, based on the situation of fig. 10a, assuming that the PUCCH of the first HARQ-ACK (i.e. HARQ-ACK-1) uses PUCCH format 2 or 3 or 4, according to the existing multiplexing transmission rule of multiple channel overlapping, a channel a with the earliest starting time, i.e. PUCCH of HARQ-ACK-1, is first determined, and the channel set X overlapping with channel a is determined to be the PUCCH carrying SR. And determining a PUCCH resource set according to the total bit number of the HARQ-ACK-1 and the SR according to a multiplexing rule, and determining a PUCCH resource in the determined PUCCH resource set according to the PUCCH resource indication field in the DCI corresponding to the HARQ-ACK-1, wherein the PUCCH resource is used for carrying the simultaneous transmission of the HARQ-ACK-1 and the SR. Continuing to replace resource a and resource X with this resource, the above multiplexing transmission rule is further repeated for the overlapping channel.

1) If the determined multiplexing resource overlaps with another HARQ-ACK (e.g., HARQ-ACK-2 in fig. 10 a) in the time domain, as shown in fig. 12a, according to the multiplexing transmission rule, at this time, it is determined that the resource a is a PUCCH resource carrying the first HARQ-ACK (i.e., HARQ-ACK-1) and the SR, and it is determined that the resource X overlapping with the resource a is a PUCCH of the second HARQ-ACK (i.e., HARQ-ACK-2), according to the multiplexing transmission rule, it is necessary to find one PUCCH resource for simultaneously transmitting the first HARQ-ACK, the SR and the second HARQ-ACK according to the total number of bits of the first HARQ-ACK, the SR and the second HARQ-ACK (the step of determining this resource is the same as above, and one PUCCH resource is determined according to the total number of bits of PUCCH resource indication fields in DCI corresponding to the HARQ-ACK), that is, it is satisfied that the HARQ-ACKs of multiple TDM are determined to be transmitted on the same PUCCH according to the multiplexing transmission rule, and then the SR is not overlapped with the HARQ-ACK, and the two HARQ-ACKs can be transmitted independently on the respective resources.

2) If the determined multiplexing resource does not overlap with the HARQ-ACK-2 in the time domain, as shown in FIG. 12b, the HARQ-ACK-1 and the SR are transmitted simultaneously on this multiplexing resource, and the HARQ-ACK-2 is transmitted directly on the PUCCH of the HARQ-ACK-2.

Example 2, based on the situation of fig. 10a, assuming that PUCCH carrying HARQ-ACK-1 uses PUCCH format 1, SR is positive SR (positive SR), PUCCH carrying SR uses PUCCH format 1, according to the existing multiplexing transmission rule of multiple channel overlapping, first determining a channel a with earliest starting time, that is, PUCCH carrying HARQ-ACK-1, and determining channel set X overlapping with channel a as PUCCH carrying SR, HARQ-ACK-1 may be transferred to SR resources for simultaneous transmission with SR according to the multiplexing rule, and transmitting HARQ-ACK by using SR resources implicitly expresses simultaneous SR transmission, that is, determining the resource carrying simultaneous transmission of HARQ-ACK-1 and SR as PUCCH of SR; since this resource overlaps with another HARQ-ACK (i.e., HARQ-ACK-2) resource, it is determined that multiple TDM HARQ-ACKs need to be transmitted on the same PUCCH according to a multiplexing rule (e.g., the multiplexing rule is that if the PUCCH of the second HARQ-ACK uses PUCCH format 2 or 3 or 4, one PUCCH resource needs to be found for simultaneously transmitting the first HARQ-ACK, CSI, and the second HARQ-ACK according to the total number of bits of the first HARQ-ACK, SR, and the second HARQ-ACK, as shown in fig. 12c, if the PUCCH of the second HARQ-ACK uses PUCCH format 1, the second HARQ-ACK is transferred to the SR resource for transmission, as shown in fig. 12 d), the drop SR, because there is no overlap of SR and HARQ-ACK after the drop SR, and the two HARQ-ACKs can be independently transmitted on the respective resources.

Based on the case of fig. 10b, if the channel a with the earliest starting position is determined to be the PUCCH for carrying the SR according to the multiplexing transmission rule, and the set of channels X overlapping with the channel a is determined to be PUCCH resources for carrying HARQ-ACK-1 and HARQ-ACK-2, then one resource needs to be determined for transmitting HARQ-ACK-1, HARQ-ACK-2 and SR simultaneously, that is, if it is satisfied that the HARQ-ACKs of multiple TDM are determined to need to be transmitted on the same PUCCH according to the multiplexing transmission rule (for example, when one HARQ-ACK uses PUCCH format 2 or 3 or 4, the multiplexing transmission rule is specifically, then one PUCCH resource needs to be found for transmitting HARQ-ACK-1, SR and HARQ-ACK-2 simultaneously according to the total number of bits of HARQ-ACK-1, SR and HARQ-ACK-2, as shown in fig. 12e, then it is determined that both HARQ-ACKs are transferred to SR resources for transmission, as shown in fig. 12 d), drsr may be transmitted on the two HARQ-ACK resources independently, because there is no overlap between SR and HARQ-ACK after drop.

Second determination mode

When the first PUCCH carrying the SR overlaps with the plurality of second PUCCHs carrying HARQ-ACKs that do not overlap in time domain, if it is determined that the PUCCHs carrying the first HARQ-ACK and the SR simultaneously overlap with the PUCCH carrying the second HARQ-ACK in time domain, the terminal device discards the SR, as shown in fig. 13.

In example 1, based on the situation of fig. 10a, assuming that PUCCH of HARQ-ACK-1 uses PUCCH format 2 or 3 or 4, according to the existing multiplexing transmission rule of overlapping multiple channels, first determining a channel a with earliest starting time, that is, PUCCH of HARQ-ACK-1, determining that a channel set X overlapping the channel is PUCCH carrying CSI, determining a PUCCH resource set according to the multiplexing transmission rule according to the total number of bits of HARQ-ACK-1 and CSI, and determining a PUCCH resource in the determined PUCCH resource set according to the PUCCH resource indication field in DCI corresponding to HARQ-ACK-1, for carrying HARQ-ACK-1 and SR for simultaneous transmission.

1) If the determined multiplexing resource overlaps with the HARQ-ACK-2 in the time domain, as shown in fig. 14a, that is, it is satisfied that the PUCCH resource carrying a certain HARQ-ACK and SR determined according to the multiplexing transmission rule overlaps with another PUCCH resource carrying a HARQ-ACK in the time domain, the drop SR, because there is no overlap of SR and HARQ-ACK after the drop SR, the two HARQ-ACKs may be independently transmitted on the respective resources.

2) If there is no overlap in the time domain between the determined multiplexing resource and the HARQ-ACK-2, as shown in FIG. 14b, the HARQ-ACK-1 and the SR are transmitted simultaneously on this resource, and the HARQ-ACK-2 is transmitted directly on the PUCCH of the HARQ-ACK-2.

Example 2, based on the case of fig. 10a, assuming that PUCCH for carrying HARQ-ACK-1 uses PUCCH format 1, SR uses PUCCH format 1, and SR is posivce SR (positive SR), according to the existing multiplexing transmission rule of multiple channel overlapping, first determining a channel a with earliest starting time, i.e. PUCCH of HARQ-ACK-1, and determining channel set X overlapping with the channel as PUCCH carrying SR, HARQ-ACK-1 may be transferred to SR resource for simultaneous transmission with SR according to the multiplexing rule, and transmitting HARQ-ACK by using SR resource implicitly expresses simultaneous SR transmission, i.e. determines PUCCH carrying HARQ-ACK-1 and SR for simultaneous transmission as SR; since this resource overlaps with another HARQ-ACK (HARQ-ACK-2) resource, the drop SR, since there is no overlap of SR and HARQ-ACK after the drop SR, the two HARQ-ACKs can be transmitted independently on the respective resources, as shown in fig. 14 c.

Third determination mode

When the first PUCCH carrying the SR overlaps with the plurality of second PUCCHs carrying HARQ-ACKs that do not overlap in the time domain, if the starting position of the first PUCCH carrying the SR is earliest, as shown in fig. 12b, the terminal device discards the SR.

Fourth determination mode

When the first PUCCH carrying the SR overlaps with the plurality of second PUCCHs carrying HARQ-ACKs that do not overlap in time domain, if the SR is positive (i.e., a positive SR and both PUCCH format 0 and PUCCH format 1 are used for transmission by the SR), and the plurality of second PUCCHs both PUCCH format 1 are used for transmission of HARQ-ACKs, the terminal device discards the SR because simultaneous transmission of the SR and HARQ-ACKs cannot be supported by PUCCH format 1 in this case (when the SR uses PUCCH format 0, if the starting position of the SR lags behind the first HARQ-ACK, the SR is multiplexed with the first HARQ-ACK according to a multiplexing rule, when HARQ-ACK uses PUCCH format 1, and when the SR uses PUCCH format 1, both HARQ-ACKs will eventually be caused to be transmitted on PUCCH format 1 resources of the SR due to overlapping with both HARQ-ACKs, and PUCCH format 1 cannot support such transmission).

The four possible preset dropping conditions are described in the four determining manners, that is, the terminal device may finally select to drop the first UCI (e.g. SR) in the four determining manners described above, so as to avoid transmission collision between the HARQ-ACK and the first UCI in the dropping manner, thereby ensuring that each HARQ-ACK can independently perform information transmission on the PUCCH resources configured respectively, ensuring the validity of HARQ-ACK transmission as much as possible, and improving the reliability of the communication system. Meanwhile, for the case that the first UCI is not discarded, a multiplexing transmission manner among a plurality of UCI is also provided.

In the second example, the first UCI is replaced by the SR and the first UCI is the HARQ-ACK with a priority lower than that of the HARQ-ACK carried on the second PUCCH, and the specific process may be understood with reference to the description of using the first UCI as the SR, where the specific process is not repeated for brevity of line text, assuming that the first UCI is transmitted using one of the PUCCH formats 0 or 1 or that the number of bits of the first UCI does not exceed 2 bits. The terminal device can avoid transmission conflict among a plurality of HARQ-ACKs with different priority levels in a discarding mode, so that the HARQ-ACKs transmitted on the second PUCCH with higher priority levels can be ensured to independently transmit information on the PUCCH resources configured respectively, and the effectiveness of the HARQ-ACK transmission is ensured.

Example three

In example three, an overlapping situation is described when a first PUCCH carrying a first UCI overlaps with a second PUCCH carrying a first HARQ-ACK in the time domain, and a third PUCCH carrying the first HARQ-ACK and the first UCI overlaps with a fourth PUCCH carrying a second HARQ-ACK in the time domain, for example, one PUCCH carrying a HARQ-ACK overlaps with one PUCCH resource carrying CSI and/or SR, as shown in fig. 15, where "CSI/SR" in fig. 15 indicates CSI and/or SR, and CSI/SR "in subsequent figures are all understood in the same way as" CSI/SR "in fig. 15.

As shown in fig. 15, HARQ-ACK-1 and HARQ-ACK-2 are transmitted in one slot, and CSI/SR is also transmitted in the slot, it can be seen that HARQ-ACK-1 and CSI/SR overlap in the time domain, and HARQ-ACK-2 and CSI/SR at this time are not overlapped in the time domain.

Assuming that the PUCCH for carrying HARQ-ACK uses PUCCH format 2 or 3 or 4, according to the existing multiplexing transmission rule that HARQ-ACK overlaps CSI/SR, determining a PUCCH resource set according to the total number of bits of HARQ-ACK and CSI/SR, and according to the PUCCH resource indication field in DCI corresponding to the first HARQ-ACK (e.g. HARQ-ACK-1, of course, also may be HARQ-ACK-2), determining a PUCCH resource in the determined PUCCH resource set, for carrying the first HARQ-ACK and HARQ-ACK for simultaneous transmission.

1) If there is overlap in the time domain between this resource and the second HARQ-ACK (when the first HARQ-ACK is HARQ-ACK-1, the second HARQ-ACK is HARQ-ACK-2, and when the first HARQ-ACK is HARQ-ACK-2, the second HARQ-ACK is HARQ-ACK-1), as shown in fig. 16a, according to the multiplexing transmission rule, a PUCCH resource is found for transmitting the first HARQ-ACK, the CSI/SR, and the second HARQ-ACK simultaneously according to the total number of bits of the first HARQ-ACK, the CSI/SR, and the second HARQ-ACK (the step of determining this resource specifically is the same as determining one PUCCH resource set according to the total number of bits, and determining one PUCCH resource according to the PUCCH resource indication field in the DCI corresponding to the HARQ-ACK), that is, the PUCCH resource carrying the HARQ-ACK and the CSI/SR will overlap in the time domain with the PUCCH resource carrying the other HARQ-ACK, and the two HARQ-ACK resources can be transmitted independently and timely, respectively, because there is no overlap between the CSI/SR and the first HARQ-ACK and the second HARQ-ACK.

2) If there is no overlap in the time domain between this resource and the second HARQ-ACK, as shown in fig. 16b, the first HARQ-ACK and CSI/SR are transmitted simultaneously on this resource, and the second HARQ-ACK is transmitted directly on the second HARQ-ACK PUCCH.

In this embodiment, when the PUCCH resource carrying HARQ-ACK and the PUCCH resource carrying CSI/SR overlap, after multiplexing PUCCH resources are selected for these UCI based on a multiplexing transmission rule, the multiplexed PUCCH resources may require multiple HARQ-ACKs to be simultaneously transmitted on the same PUCCH, thereby causing resource collision between HARQ-ACKs, that is, multiple HARQ-ACKs that are not originally overlapped need to be simultaneously transmitted on one PUCCH due to overlapping of the PUCCH resource carrying HARQ-ACK and the PUCCH resource carrying SR, that is, multiple HARQ-ACKs may be discarded due to overlapping of the PUCCH resource carrying HARQ-ACK and the PUCCH resource carrying CSI/SR, so as to avoid placing multiple HARQ-ACKs that are not originally overlapped on the same PUCCH resource for simultaneous transmission, thereby improving the effectiveness and timeliness of HARQ-ACK transmission.

In the embodiment of the application, since the HARQ-ACK is real-time feedback for the terminal device to feed back whether the downlink data is successfully received to the network device, once the time delay of the HARQ-ACK transmission is affected, the time delay of the downlink transmission is directly affected, and once the transmission performance of the HARQ-ACK is affected, the downlink throughput is directly affected, so that a lot of unnecessary retransmissions are caused, so that the HARQ-ACK transmission is important; the CSI and the SR are, for example, some scheduling requests periodically reported or used for performing data scheduling, and even if one transmission opportunity is missed, there is still another transmission opportunity to continue transmission, so when there is resource overlapping between the HARQ-ACK and the first UCI, the transmission of the HARQ-ACK can be preferentially ensured and the first UCI is discarded, so that the HARQ-ACK can be ensured to be timely and effectively transmitted to the network side, and the timeliness of data interaction between the data terminal side and the network side can be ensured as much as possible.

Referring to fig. 17, another flow chart corresponding to an information transmission method provided in the embodiment of the present application is shown, where the method may be executed by a network device (e.g. a gNB), and specifically includes the following steps.

Step 171: the network equipment determines that a first PUCCH carrying a first UCI and a plurality of second PUCCHs carrying HARQ-ACKs which are not overlapped in the time domain are overlapped in the time domain; or when the network device determines that the first PUCCH carrying the first UCI overlaps with the second PUCCH carrying the first HARQ-ACK in the time domain, if it is determined that the third PUCCH carrying the first HARQ-ACK and the first UCI overlaps with the fourth PUCCH carrying the second PUCCH in the time domain.

Step 172: the network device determines that the first UCI is discarded.

In a possible implementation manner, the first UCI in the embodiment of the present application may be another type of UCI different from HARQ-ACK, for example, the first UCI is SR, or is CSI, or includes CSI and SR at the same time, i.e., the first UCI is CSI and/or SR. In another possible implementation manner, the first UCI in the embodiment of the present application may be an HARQ-ACK, where the HARQ-ACK in the first UCI is an HARQ-ACK with a priority lower than that of the HARQ-ACK carried on the second PUCCH.

In one possible implementation, when the network device determines that the first PUCCH carrying the first UCI overlaps with the second PUCCHs carrying the HARQ-ACKs that do not overlap in the time domain, the network device may determine that the first UCI is discarded by the terminal device when it determines that the plurality of HARQ-ACKs need to be transmitted simultaneously on the same PUCCH, for example, when it determines that the plurality of HARQ-ACKs need to be transmitted simultaneously on the same PUCCH based on a multiplexing transmission rule.

In another possible implementation manner, when the network device determines that the first PUCCH carrying the first UCI overlaps with the second PUCCHs carrying HARQ-ACKs that do not overlap in time domain, the network device may determine that the first UCI is discarded by the terminal device when determining that the PUCCHs carrying the first HARQ-ACK and the first UCI simultaneously overlap with the PUCCHs carrying the second HARQ-ACK in time domain.
