Detailed Description

The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

In the prior art, as shown in fig. 1, PUSCH supports only one repetitive transmission scheme, i.e., slot-based repetitive transmission, in R15. Specifically, the higher layer signaling (for example, the PUSCH-Aggregation factor) configures the number of times of retransmission (also referred to as Aggregation factor, which is denoted by N for simplicity) in advance, and N times of retransmission, which means that the PUSCH occupies N slots for transmission, and the same TB information is transmitted on the same PUSCH resource in each slot. The time domain position of the PUSCH transmission in each slot is determined according to the same starting symbol and symbol number, if a downlink symbol configured by higher layer signaling (e.g., tdd-UL-DL-configuration common, ortdd-UL-DL-configuration determined) is included in a symbol set determined according to the starting symbol and symbol number in one slot, it is determined that the symbol set is unavailable, and the PUSCH is not transmitted in the slot, but one retransmission is recorded, that is, if the symbol set determined in N1 slots of N slots is unavailable, only N-N1 retransmissions actually occur. The PUSCH expands the repeated transmission in R15 to some extent in R16, except that the repetition times are configured in advance by the high layer signaling, a column of information may be added in the TDRA table to express the repetition times (configured by repetition number-R16), the Downlink Control information DCI (Downlink Control information) (DCI for scheduling PUSCH or physical Downlink Control channel PDCCH (physical Downlink Control channel) is called UL grant, DCI and PDCCH may be considered equivalent in describing scheduling and information indication, PDCCH is a format specifically used for transmission, DCI is a channel for carrying DCI, and when a PUSCH transmission is dynamically scheduled, an appropriate repetition times and information related to the time Domain resources (e.g. start and length indicator value (start and length indicator) and timing information (2)) may be selected from the table of TDRA time Domain Resource allocation (DCI Resource allocation) for dynamically scheduling, and the terminal may send the scheduling information together with the start symbol and the timing indicator value (2), thus, the dynamic change of the repeated transmission times is realized, and the repeated transmission is called repetition type A. In addition, a repetition type B is also supported, that is, a transmission opportunity (i.e., a time domain resource, which is specifically represented as a symbol set) of each repetition is determined by the number of transmission symbols according to a starting symbol indicated in a PDCCH (or DCI) for scheduling a PUSCH, and the number of repeated transmissions may be obtained in a manner similar to that of the repetition type a; the time domain resource of the first retransmission PUSCH is directly determined according to the initial symbol and the number of symbols indicated by the DCI, and the time domain resource of the subsequent retransmission is sequentially determined after the first retransmission. Specifically, each transmission opportunity corresponds to the same number of symbols, and the starting point is the first symbol after the previous repetition, so that N consecutive repetition transmission opportunities are obtained by dividing, and each transmission opportunity becomes a Nominal repetition (Nominal repetition, that is, a repetition divided according to the configuration parameters, but not necessarily actual transmission). If a symbol set corresponding to a Nominal repetition contains DL symbols or SSB symbols or unavailable symbols configured by a higher layer signaling or crosses a slot boundary, the Nominal repetition is divided into multiple Actual repetitions (Actual repetition), and each Actual repetition contains only symbols that can be used for uplink transmission, such as uplink symbols or Flexible symbols. The plurality of retransmission PUSCHs can be in the same time slot or distributed in different time slots. As shown in particular in figure 1. For an Actual repetition with a relatively short transmission length (number of symbols) obtained in the course of the Nominal-to-Actual division, for example, an Actual repetition with 1 symbol, such an Actual repetition is not transmitted unless the transmission length configured by the scheduling signaling is 1 symbol. For each Actual repetition, the DMRS mapping rule therein determines a DMRS symbol position according to a mapping manner in one PUSCH in the prior art.

In the prior art, as shown in fig. 2, for the same terminal, simultaneous transmission of PUCCH and PUSCH is not supported in order to avoid an excessive Peak-to-Average Power Ratio PARR (Peak-to-Average Power Ratio), so when time domain resources between PUCCH and PUSCH overlap, the terminal may multiplex UCI on PUSCH for transmission, so that PUCCH does not need to be transmitted, or a higher priority channel is selected based on physical layer priority for transmission, and a low priority channel is not transmitted. When there is a collision (so-called collision, which may overlap on time domain resources, or, for high frequency transmission, the time interval between two channels is shorter than a predetermined time interval, so that high frequency device adjustment is not sufficient, and the same is explained later) in one or more slots between a PUSCH (including a single slot and repeated transmission) and a single slot PUCCH (without repeated transmission) of the same physical layer priority, for the single slot PUSCH or the PUSCH repeatedly transmitted using repetition Type-a, the terminal multiplexes UCI carried by the PUCCH on all PUSCHs overlapping with the PUCCH for transmission. For the PUSCH repeatedly transmitted by using the repetition Type-B, the terminal multiplexes UCI carried by the PUCCH on a true (actual) PUSCH with the number of first symbols overlapped with the PUCCH larger than 1. When the resources of the PUSCH (including single-slot and repeated transmission) and the multi-slot PUCCH (allocated with repeated transmission) with the same physical layer priority are in conflict, the PUSCH channel is discarded in the conflicting slots, and only the PUCCH is transmitted. When resources of PUCCH and PUSCH with different physical layer priorities conflict, channels with lower priorities are discarded, and only channels with higher priorities are transmitted. At present, HARQ-ACK and CSI carried by a PUCCH can be transmitted through a PUSCH, if the SR exists on the PUCCH, unless the PUSCH is the PUSCH only carrying Semi-persistent channel state information SP-CSI (Semi-persistent CSI), the PUSCH is discarded at the moment, and otherwise, the SR is discarded. When the number of HARQ-ACK bits is not more than 2, HARQ-ACK is carried out punching transmission on a PUSCH (namely, a TB is always encoded according to the PUSCH resource under the condition of no HARQ-ACK, and when HARQ-ACK is mapped, data at corresponding positions are knocked out, namely the data are covered); and when the number of the HARQ-ACK bits is more than 2, carrying out rate matching transmission on the PUSCH by the HARQ-ACK (namely, when the TB or CSI coding is carried out on the PUSCH, removing the resources used for the HARQ-ACK transmission on the PUSCH, and carrying out coding based on the residual resources on the PUSCH). The TBs on CSI and PUSCH are always rate matched transmitted. HARQ-ACK and CSI are mapped on all layers corresponding to TB on PUSCH for transmission. The HARQ-ACK maps starting from the first non-DMRS symbol after the first DMRS on PUSCH. And when the number of the HARQ-ACK bits is not more than 2, reserving a part of resources. When the HARQ-ACK bit is 0,1,2, HARQ-ACK resource reservation is always carried out according to 2 bits, if the actual HARQ-ACK is 1 bit, mapping is carried out on a part of resources in the reserved resources. The CSI is mapped from the first non-DMRS symbol on the PUSCH, when the information bit of the HARQ-ACK is less than 2, reserved resources of the HARQ-ACK exist on the PUSCH, the CSI part 1 is not mapped on the reserved resources, and the CSI part 2 and the TB can be mapped on the reserved resources; if the information bit of the HARQ-ACK is greater than 2, none of the CSI part 1, CSI part 2, and TB are mapped on the HARQ-ACK resource. And the UCI performs frequency domain discrete mapping in the transmission bandwidth of the PUSCH according to the sequence of the frequency domain first and the time sequence second. For a certain UCI type, the interval d between modulation symbols on one OFDM symbol is determined as follows: if the number of the remaining unmapped modulation symbols of the UCI is greater than or equal to the number of usable REs on the current OFDM symbol, d is 1; otherwise, d is floor (number of REs available on the current OFDM symbol/number of remaining unmapped modulation symbols of UCI), and floor is rounding down. As shown in fig. 3, the collision refers to a collision in the same carrier Group, for example, when a Primary carrier Group MCG (master) Cell Group) and a Secondary carrier Group SCG (Secondary Cell Group) in a dual link are in a carrier Group, for example, PUCCH transmission on the SCG is supported, a Primary PUCCH Group (Primary PUCCH Group) and a Secondary PUCCH Group (Secondary PUCCH Group) may occur, and each PUCCH Group is a carrier Group.

For the current R17 positioning method, Coverage enhancement (Coverage enhancement) is proposed because the Coverage of signal or channel transmission may be affected by the interference of complex environment or cell edge. In addition, in order to reduce the cost and volume of a new wireless nr (new rat) terminal and better meet the requirements of wearable devices, a complexity-reduced terminal (RedCap terminal) is proposed, and for such a terminal, the transmission performance may be reduced due to the reduction of complexity and hardware indexes, such as reduction of bandwidth and antennas, and a certain coverage enhancement is also required to compensate for the reduction of the transmission performance.

As shown in fig. 4, for a terminal that needs coverage enhancement, the prior art is studying to process TB (TB processing over multiple slots) across multiple slots (slots), which is referred to as multi-slot TB transmission in the following. The transmission of multi-slot TB on PUSCH is different from the repeated transmission of PUSCH in the prior art, in the repeated transmission, although PUSCH may also occupy multiple slot transmissions, the repeated transmission of the same TB is performed in each slot, that is, each TB is encoded based on PUSCH resources in one slot, and then is repeatedly transmitted in each slot, and in each slot, there is an independent PUSCH transmission. In the time slot TB processing method, one TB is coded based on PUSCH total resources in a plurality of time slots, namely the TB is jointly coded based on a plurality of time slots, but not an independent coding mode in each time slot; it can be understood that "one TB is transmitted in multiple PUSCHs in multiple slots, and each PUSCH carries a part of the coded TB", and it can also be understood that "one TB is transmitted in one PUSCH, but the length of the PUSCH spans multiple slots". Fig. 4 gives an example of a comparison of repetition type a and cross-slot TB transmission, where TBs is both the transport block Size (TB Size). By multi-slot TB transmission, the coding rate can be reduced, the code length of coding can be increased, the coding performance is improved, and the coverage is equivalently enhanced. However, for the case of multi-slot TB transmission in PUSCH, there is currently no clear solution if a collision of PUCCH with PUSCH occurs. In order to solve the problem, an embodiment of the present application provides an information transmission method, where when there is a time domain conflict between a physical uplink shared channel PUSCH for carrying a multi-slot transport block TB and a physical uplink control channel PUCCH, uplink control information UCI on the PUCCH is transferred to a target PUSCH and transmitted, so that UCI is normally transmitted on the PUSCH for carrying the multi-slot TB, thereby avoiding UCI discarding and improving transmission performance of a system.

The present application is explained in detail below.

As shown in fig. 5, a flowchart of steps of an information transmission method applied to a terminal device provided in the embodiment of the present application is shown, where the method includes the following steps:

step 101: when a Physical Uplink Shared Channel (PUSCH) carrying a multi-slot Transport Block (TB) conflicts with a Physical Uplink Control Channel (PUCCH) in a time domain, transferring Uplink Control Information (UCI) on the PUCCH to a target PUSCH for transmission; and the target PUSCH is a PUSCH which conflicts with the PUCCH or all PUSCHs which correspond to the same TB in a time slot in which the PUSCH which conflicts with the PUCCH is positioned.

In this step, for a physical uplink shared channel PUSCH carrying a multi-slot transport block TB, when there is a collision with a physical uplink control channel PUCCH in a time domain, uplink control information UCI on the PUCCH is transferred to a target PUSCH for transmission, where the target PUSCH is a PUSCH colliding with the PUCCH or all PUSCHs corresponding to the same TB in a slot in which the PUSCH colliding with the PUCCH is located. For example, if the PUSCH carrying the multi-slot TB is referred to as one PUSCH in multiple slots, which means that a part of symbols of this PUSCH in a certain slot collide with the PUCCH, UCI may be transferred to the one PUSCH transmitted in multiple slots; if the PUSCH carrying the multi-slot TB is called an independent PUSCH in each slot, the PUSCH where there is a collision is a certain independent PUSCH and no other PUSCH is involved.

According to the information transmission method provided by the embodiment of the application, when the Physical Uplink Shared Channel (PUSCH) carrying the multi-slot Transport Block (TB) conflicts with the Physical Uplink Control Channel (PUCCH) in the time domain, the Uplink Control Information (UCI) on the PUCCH is transferred to the target PUSCH to be transmitted.

Based on the content of the foregoing embodiments, in this embodiment, when uplink control information UCI on the PUCCH is transferred to a target PUSCH and transmitted, the UCI is mapped onto the target PUSCH according to a predetermined mapping rule.

In this embodiment, it should be noted that, when there is a collision between the PUSCH carrying the multi-slot transport block TB and the PUCCH in the time domain, the UCI of the PUCCH is mapped onto the target PUSCH according to a predetermined mapping rule. The predetermined mapping rule includes:

Based on the content of the above embodiment, in the present embodiment, the predetermined mapping rule includes at least one of the following:

In this embodiment, it should be noted that the mapping of UCI on the target PUSCH includes three rules. Optionally, the first mapping rule is centralized mapping, and symbols included in a PUSCH having a collision with a PUCCH are used as a symbol set to be mapped in the symbol set; the second mapping rule is based on the distributed mapping of the PUSCHs, each PUSCH which conflicts with the PUCCH is taken as an independent individual, and symbols contained in each PUSCH are taken as a symbol set to be mapped in each symbol set; the third mapping rule is slot-based distributed mapping, in which symbols corresponding to the PUSCH in collision with the PUCCH are divided into multiple groups, symbols corresponding to the PUSCH transmitted in the same slot (slot divided by the SCS of the PUSCH) are grouped into one group to form one symbol set, and mapping is performed in each symbol set.

Based on the content of the foregoing embodiment, in this embodiment, the UCI is at least one of HARQ-ACK, CSI, and SR.

In this embodiment, it should be noted that the UCI is at least one of HARQ-ACK, CSI, and SR; different UCI types may select the same or different mapping rules as described above, and are not particularly limited herein. Wherein, HARQ-ACK (Hybrid Automatic Repeat request-acknowledgement) is a general term for ACK and NACK feedback information, and the subsequent HARQ-ACK is abbreviated as AN.

Based on the content of the foregoing embodiment, in this embodiment, when mapping is performed on one of the mapping rule 1, the mapping rule 2, and the mapping rule 3 in the compliance set, at least one of the following mapping manners is included:

mapping mode 3: mapping the UCI to continuous symbols from a predefined symbol;

In this embodiment, it should be noted that, for three mapping rules of UCI on a target PUSCH, when mapping is performed in a symbol set, four mapping manners are included, which are respectively:

mapping mode 1: mapping is started from the first symbol available for transmitting UCI, and UCI is mapped to consecutive symbols (specifically, how many resources are occupied by UCI is pre-calculated, and it is sufficient to map all resources occupied by UCI, which is explained in the same way later, and is not described any further). It should be noted that this scheme is preferably applied to the CSI and may also be applied to the AN, and is not particularly limited herein.

The mapping mode 2: mapping is started from a first symbol which is used for transmitting UCI after a first demodulation reference signal (DMRS), and the UCI is mapped to continuous symbols. If there is no DMRS in a certain PUSCH (because of an unavailable symbol, a PUSCH divided by a slot boundary, etc.), mapping is performed based on an assumed DMRS position, where the assumed DMRS position may be the first symbol or the same as the relative position of the DMRS in the previous PUSCH containing the DMRS or the next PUSCH containing the DMRS (for example, the DMRS position in the previous PUSCH is the 3 rd symbol in the symbols contained in this PUSCH, the assumed DMRS in this PUSCH is located in the 3 rd symbol in the symbols contained in this PUSCH). It should be noted that this scheme is preferably applied to the AN and may also be applied to the CSI, and is not particularly limited herein.

Mapping mode 3: mapping is started from a predefined symbol, and UCI is mapped to consecutive symbols.

Mapping mode 4: mapping around each DMRS symbol, determining symbols which are available for UCI transmission of one or adjacent DMRS before and after the DMRS in the symbol set (namely when the spread spectrum orthogonal frequency division multiplexing DFT-s-OFDM based on discrete Fourier transform is used, either the symbols which are the DMRS symbols or the symbols which are available for UCI transmission, and when the orthogonal frequency division multiplexing OFDM is used, except the symbols which are not used for DMRS transmission, if RE which can be used for TB transmission exists on the symbols which are used for DMRS transmission, the symbols which are used for DMRS transmission can also be used as the symbols for carrying UCI transmission) as mapping symbols of UCI. Specifically, the DMRS symbols are divided into N groups, the DMRS symbols in each group are adjacent, the DMRS symbols in different groups are not adjacent, the mapping symbols of the UCI may be distributed around each group of DMRS as uniformly as possible, that is, the number of the mapping symbols of the UCI around each group of DMRS differs by no more than 1 symbol, and when the number of the mapping symbols of the UCI around different groups of DMRS differs, more mapping symbols of the UCI exist around the former DMRS group; or the mapped symbols of the UCI are preferentially distributed on symbols available for UCI transmission around the previous DMRS group.

Based on the content of the above embodiment, in this embodiment, for mapping manner 2:

In this embodiment, it should be noted that, for the mapping scheme 2, if there is no DMRS in a certain PUSCH (one PUSCH divided by an unavailable symbol, a slot boundary, or the like), mapping is performed based on an assumed DMRS position, where the assumed DMRS position may be the first symbol or the same as the relative position of the DMRS in the previous PUSCH including the DMRS or the next PUSCH including the DMRS (for example, the DMRS position in the previous PUSCH is the 3 rd symbol in the symbol included in this PUSCH, the assumed DMRS in this PUSCH is the 3 rd symbol in the symbol included in this PUSCH). It should be noted that this scheme is preferably applied to the AN and may also be applied to the CSI, and is not particularly limited herein.

Based on the content of the foregoing embodiment, in this embodiment, the mapping method 4 includes:

In this embodiment, for the mapping mode 4, the DMRS symbols may be divided into N groups, where DMRS symbols in each group are adjacent, DMRS symbols in different groups are not adjacent, and the mapping symbols of UCI may be distributed around each group of DMRSs as uniformly as possible, that is, the number of the mapping symbols of UCI around each group of DMRSs differs by no more than 1 symbol, and when the number of the mapping symbols of UCI around different groups of DMRSs is different, there are more mapping symbols of UCI around the former DMRS group; or the mapped symbols of the UCI are preferentially distributed on symbols available for UCI transmission around the previous DMRS group.

Based on the content of the foregoing embodiment, in this embodiment, the mapping method 4 includes: a uniform distribution mode and/or a forward distribution mode;

wherein, the uniform distribution mode comprises a mode A and/or a mode B;

the mode B comprises the following steps: firstly, determining X1 symbols which are nearest to the symbols of each group of DMRS and can be used for UCI transmission, if the size of the mapping resources of 1/X1 UCI does not exceed the size of the resources carrying UCI on one symbol of X1 symbols, using the X1 symbols as the mapping symbols of UCI, and uniformly distributing the mapping resources of UCI on the X1 symbols; otherwise, further determining X2 symbols of the nearest adjacent X1 symbols available for UCI transmission, and if the size of the mapping resources of 1/(X1+ X2) UCI does not exceed the size of the resources carrying UCI on one symbol of X1+ X2 symbols, regarding the X1+ X2 symbols as the X1+ X2 symbolsMapping symbols of UCI, uniformly distributing mapping resources of UCI on the X1+ X2 symbols, otherwise, determining X3 symbols which are the nearest to X2 symbols and can be used for UCI transmission, and analogizing until satisfying

wherein, the forward distribution mode comprises: starting from the 1 st group of DMRS symbols, taking the nearest adjacent 1 symbol before and after the group of DMRS symbols which can be used for carrying UCI to form A1 symbols, if the size of the mapping resource of UCI does not exceed the total resource size of UCI carried on the A1 symbols, determining the A1 symbols as the mapping symbols of UCI, otherwise, taking the nearest adjacent 1 symbol before and after the group of DMRS symbols which can be used for carrying UCI to form A2 symbols, if the size of the mapping resource of UCI does not exceed the total resource size of UCI carried on the A1+ A2 symbols, determining the A1+ A2 symbols as the mapping symbols of UCI, and analogizing until the size of the mapping resource which meets the UCI does not exceed the total resource size of all the symbols which can be used for carrying UCI and which has been determined; after the last group of DMRS symbols is subjected to the operations, the size of the mapping resource which still can not meet the UCI does not exceed the total resource size on all the determined symbols for carrying the UCI, starting from the first group of DMRS, the nearest B1 symbols which are before and after the A1 symbols corresponding to the group of DMRS symbols and can be used for carrying the UCI are taken, if the size of the mapping resource of the UCI does not exceed the total resource size on all the determined symbols for carrying the UCI, the method comprises the steps of

Determining the total resource size of UCI carried on each symbol

In this embodiment, when the mapping manner 4 is uniformly distributed, one manner (uniformly distributed among each set of DMRSs) is: firstly, determining X1 symbols which are nearest to each group of DMRS symbols (namely 1 symbol before and after each group of DMRS symbols, wherein the front or back of each group of DMRS symbols may not have any symbol, only one side of the symbol is needed), if the size of UCI mapping resources does not exceed the total resource size of UCI carried on X1 symbols, using the X1 symbols as UCI mapping symbols, and uniformly distributing the UCI mapping resources on the X1 symbols; otherwise, further determining X2 symbols which are nearest to X1 symbols and can be used for UCI transmission, if the size of mapping resources of the UCI does not exceed the total resource size of UCI carried on X1+ X2 symbols, taking the X1+ X2 symbols as the mapping symbols of the UCI, uniformly distributing the resources remained after the mapping resources of the UCI are fully mapped on the X1 symbols on the X2 symbols, otherwise, determining X3 symbols which are nearest to X2 symbols and can be used for UCI transmission, and so on until the size of the mapping resources meeting the UCI does not exceed the size of the mapping resources of the UCI

After one symbol, the remaining resources are at the last determined X _j Uniformly distributed on each symbol; another way (evenly distributed over each UCI-bearing symbol): firstly, determining X1 symbols which are nearest to the symbols of each group of DMRS and can be used for UCI transmission, and if the size of the mapping resource of the UCI of 1/X1 does not exceed the size of the resource carrying the UCI on one symbol of X1 symbols, regarding the A1 symbols as UCI mapping symbols, and distributing UCI mapping resources evenly on the X1 symbols; otherwise, further determining X2 symbols of the nearest X1 symbols available for UCI transmission, if the size of the mapping resources of 1/(X1+ X2) UCI does not exceed the resource size of UCI carried on one symbol of X1+ X2 symbols, taking the X1+ X2 symbols as the mapping symbols of UCI, and uniformly distributing the mapping resources of UCI on the X1+ X2 symbols, otherwise, determining X3 symbols of the nearest X2 symbols available for UCI transmission, and so on until satisfying the requirement of UCI transmission

Does not exceed the size of the mapping resource of the UCI

Evenly distributed over the symbols.

When the mapping mode 4 is forward distribution, starting from the 1 st group of DMRS symbols (DMRS with the earliest time), the nearest adjacent 1 symbol before and after the group of DMRS symbols, which can be used to carry UCI, are taken to form a1 symbols (a1 may be less than or equal to 2, because there may be no symbol before the DMRS, or there may be no symbol after the DMRS), if the size of the mapping resource of the UCI does not exceed the total resource size carrying the UCI over the a1 symbols, determining the A1 symbols as mapping symbols of UCI, otherwise, taking the nearest adjacent 1 symbol before and after a group of DMRS to form A2 symbols, if the size of the mapping resources of UCI does not exceed the total resource size carrying UCI over the a1+ a2 symbols, determining the a1+ a2 symbols as mapping symbols of UCI, and so on, until the size of mapping resources satisfying UCI does not exceed the total resource size over all symbols that have been determined to carry UCI; after the last group of DMRS symbols are subjected to the operation, the size of the mapping resource which still cannot meet the UCI does not exceed the size of the determined mapping resource for carrying the UCIThen, starting from the first group of DMRS, the B1 symbols which are closest to a1 symbols before and after the a1 symbols corresponding to the DMRS symbols and can be used for carrying UCI are taken, if the size of the mapping resources of UCI does not exceed the size of the mapping resources of UCI

It should be noted that, the mapping manner 4 may map, on the plurality of symbols determined to carry the UCI, according to an order from the frequency domain to the time sequence, or according to an order from the time domain to the frequency domain. When the mapping mode 4 is uniformly distributed, the method is more suitable for mapping the UCI in a time domain and a frequency domain; when the mapping mode 4 is forward distribution, the method is more suitable for mapping the UCI in a frequency domain before a time domain.

Based on the content of the foregoing embodiment, in this embodiment, before mapping the mapping rule 2 or the mapping rule 3 according to the mapping manner 1, the mapping manner 2, the mapping manner 3, and the mapping manner 4 in each symbol set, the method further includes:

In this embodiment, it should be noted that, for the mapping rule 2 or the mapping rule 3, before mapping according to the mapping manner 1, the mapping manner 2, the mapping manner 3, and the mapping manner 4 in each symbol set, the method further includes: determining the size of mapping resources of UCI corresponding to each symbol set; specifically, the method comprises the following steps: the original UCI information may be divided into multiple groups, each group corresponds to one symbol set, and the mapping resource size of the UCI corresponding to each symbol set is determined based on the corresponding UCI information in each symbol set. The UCI information may also be used as a whole, the total size of the UCI mapping resources is determined based on symbols included in all PUSCHs overlapped with the PUCCH, the total size of the UCI mapping resources is divided into multiple groups, and each group corresponds to one symbol set, so as to obtain the size of the UCI mapping resources corresponding to each symbol set.

Based on the content of the foregoing embodiment, in this embodiment, the determining the size of the mapping resource of the UCI corresponding to each symbol set includes the following processing manners:

In this embodiment, it should be noted that the size of the mapping resource of the UCI corresponding to each symbol set may be determined through two processing manners. The first processing mode is as follows: the UCI information is divided into a plurality of groups, each group corresponds to a symbol set, and the mapping resource size of the UCI corresponding to each symbol set is determined in each symbol set based on the corresponding UCI information. When the UCI information is grouped, the UCI information can be uniformly grouped (when the UCI information is not an integral multiple, a certain group or a plurality of groups contain more information), or the UCI information can be grouped according to a proportion; the ratio may be obtained from the ratio of each symbol set in a total symbol set, which is a symbol set made up of symbols corresponding to a PUSCH in which there is a collision with a PUCCH. The second processing mode is as follows: determining the size of the total UCI mapping resources based on symbols contained in all PUSCHs overlapped with a PUCCH by taking UCI information as a whole, dividing the size of the total UCI mapping resources into a plurality of groups, wherein each group corresponds to one symbol set, and thus obtaining the size of the UCI mapping resources corresponding to each symbol set. When the mapping resource sizes corresponding to the total UCI are grouped, the mapping resource sizes can be uniformly grouped (when the mapping resource sizes are not integer multiples, a certain group or a plurality of groups contain more information), or the mapping resource sizes can be grouped according to a proportion; the ratio may be obtained from the ratio of each symbol set in a total symbol set, which is a symbol set made up of symbols corresponding to a PUSCH in which there is a collision with a PUCCH.

Based on the content of the above embodiment, in this embodiment, for processing mode 1, when grouping UCI information, grouping uniformly or grouping according to a ratio; the proportion is obtained according to the proportion of each symbol set in a total symbol set, wherein the total symbol set is a symbol set formed by symbols corresponding to PUSCH with conflict with PUCCH.

In this embodiment, it should be noted that, for processing mode 1, when grouping UCI information, uniform grouping (where a certain group or several groups contain more information when not an integer multiple) or proportional grouping may be performed; the ratio may be obtained from the ratio of each symbol set in a total symbol set, which is a symbol set made up of symbols corresponding to a PUSCH in which there is a collision with a PUCCH.

Based on the content of the foregoing embodiment, in this embodiment, for the processing mode 2, when grouping the mapping resource sizes corresponding to the total UCI, grouping uniformly or grouping according to a ratio; the proportion is obtained according to the proportion of each symbol set in a total symbol set, wherein the total symbol set is a symbol set formed by symbols corresponding to PUSCH with conflict with PUCCH.

In this embodiment, it should be noted that, for the processing method 2, when the mapping resource sizes corresponding to the total UCI are grouped, the mapping resource sizes may be uniformly grouped (when the mapping resource sizes are not integer multiples, some group or groups contain more information), or grouped according to a ratio; the ratio may be obtained from the ratio of each symbol set in a total symbol set, which is a symbol set made up of symbols corresponding to a PUSCH in which there is a collision with a PUCCH.

Based on the contents of the above-described embodiments, in the present embodiment, after the mapping symbols are determined, on each symbol, mapping is continuously performed or mapping is discretely performed in the order from low frequency to high frequency or from high frequency to low frequency in the frequency domain.

In this embodiment, it should be noted that after the mapping symbols are determined, on each symbol, mapping may be performed continuously or discretely in the order from low frequency to high frequency or from high frequency to low frequency in the frequency domain.

Based on the content of the foregoing embodiment, in this embodiment, the symbols that can be used for UCI transmission include: symbols not carrying DMRS;

In this embodiment, it should be noted that the symbols that can be used for UCI transmission include: symbols not carrying DMRS, or determined from the waveform: when the OFDM waveform is adopted, the DMRS-non-bearing symbols and DMRS symbols with Resource Elements (REs) (resource elements) available for bearing the TB exist (that is, the DMRS on the DMRS symbol is mapped to a part of REs at intervals, and the remaining REs can be used for TB transmission, and the remaining REs are considered to also be able to transmit UCI).

Based on the content of the foregoing embodiment, in this embodiment, the conflict includes:

In this embodiment, it should be noted that, when the PUCCH and the PUSCH belong to the same carrier group, if a collision occurs, the method is performed according to the embodiment of the present application, if the collision does not belong to the same carrier group, the method may be performed according to or not according to the embodiment of the present application, and if the collision does not belong to the same carrier group, it means that simultaneous transmission of the PUCCH and the PUSCH between different carrier groups is supported. Wherein, the carrier group specifically is: for example, when a secondary carrier (SCC) is configured to transmit a PUCCH, a primary PUCCH group and a secondary PUCCH group are one carrier group respectively; for example, in a dual connectivity scenario, when a Secondary Cell Group (SCG) is configured, a Master Cell Group (MCG) and an SCG are each a carrier group.

In this embodiment, it should be noted that there is an overlap of resources in the time domain, that is, there is an overlap of the time domain resources of the PUCCH and the time domain resources of the PUSCH, where the PUCCH and the PUSCH may be on the same or different carriers.

In this embodiment, it should be noted that the symbol interval between the channels is smaller than a predetermined threshold, which may specifically be: i.e. the time interval between the end symbol of the first channel (earlier) and the start symbol of the second channel (later) is smaller than a predetermined threshold, in order to cover the case of high frequency transmission, when the two channels are high frequency and low frequency, even if they do not overlap in the time domain, a certain time interval in the time domain needs to be maintained for adjusting the rf devices, so that the process is equivalent to overlapping in the time domain.

Based on the content of the foregoing embodiment, in this embodiment, the PUSCH carrying the multi-slot TB is:

In this embodiment, it should be noted that the PUSCH for carrying the multi-slot TB specifically includes: and one TB carries out coding based on the total number of symbols corresponding to the PUSCHs in a plurality of time slots, and the obtained coding information is dispersed in the plurality of time slots and is transmitted through the corresponding PUSCHs.

As shown in fig. 6, a flowchart of steps of an information transmission method applied to a network device according to an embodiment of the present application is provided, where the method includes the following steps:

step 201: when a Physical Uplink Shared Channel (PUSCH) carrying a multi-slot Transmission Block (TB) and a Physical Uplink Control Channel (PUCCH) conflict in a time domain, receiving Uplink Control Information (UCI) in a target PUSCH; and the target PUSCH is a PUSCH which conflicts with the PUCCH or all PUSCHs which correspond to the same TB in a time slot in which the PUSCH which conflicts with the PUCCH is positioned.

In this step, it should be noted that, for a physical uplink shared channel PUSCH carrying a multi-slot transport block TB, when there is a collision in a time domain with a physical uplink control channel PUCCH, uplink control information UCI is received in a target PUSCH, where the target PUSCH is a PUSCH colliding with the PUCCH or all PUSCHs corresponding to the same TB in a slot in which the PUSCH colliding with the PUCCH is located. For example, if the PUSCH carrying the multi-slot TB is referred to as one PUSCH in multiple slots, which means that a part of symbols of the PUSCH in a certain slot collide with the PUCCH, UCI may be transferred to the one PUSCH transmitted in multiple slots; if the PUSCH carrying the multi-slot TB is called an independent PUSCH in each slot, the PUSCH where there is a collision is a certain independent PUSCH and no other PUSCH is involved.

According to the information transmission method provided by the embodiment of the application, when the Physical Uplink Shared Channel (PUSCH) carrying the multi-slot Transport Block (TB) and the Physical Uplink Control Channel (PUCCH) conflict in the time domain, the Uplink Control Information (UCI) on the PUCCH is transferred to the target PUSCH to be transmitted, so that the UCI is normally transmitted on the PUSCH carrying the multi-slot TB, the UCI is prevented from being discarded, and the transmission performance of the system is improved.

The embodiment of the application provides a transmission method when a PUCCH conflicts with a PUSCH carrying a multi-slot TB, and through the reasonable design of a mapping rule on the PUSCH carrying the multi-slot TB by the UCI, the UCI can be ensured to be normally transmitted on the PUSCH carrying the multi-slot TB, the discarding of the UCI is avoided, and the transmission performance of a system is improved.

Based on the content of the foregoing embodiment, in this embodiment, when uplink control information UCI on the PUCCH is transferred to a target PUSCH and transmitted, the UCI is mapped onto the target PUSCH according to a predetermined mapping rule.

In this embodiment, it should be noted that, when there is a collision between the PUSCH carrying the multi-slot transport block TB and the PUCCH in the time domain, the UCI of the PUCCH is mapped onto the target PUSCH according to a predetermined mapping rule. The predetermined mapping rule includes: mapping rule 1: mapping symbols contained in a PUSCH with conflict with the PUCCH in a symbol set by taking the symbols as the symbol set; mapping rule 2: taking each PUSCH which conflicts with the PUCCH as an independent individual, taking symbols contained in each PUSCH as a symbol set, and mapping in each symbol set; mapping rule 3: dividing symbols corresponding to the PUSCHs having collision with the PUCCH into a plurality of groups, forming a symbol set by taking the symbols corresponding to the PUSCHs transmitted in the same time slot as a group, and mapping in each symbol set.

In this embodiment, it should be noted that the mapping of UCI on the target PUSCH includes three rules. Optionally, the first mapping rule is centralized mapping, and symbols included in the PUSCH and conflicting with the PUCCH are used as a symbol set and mapped in the symbol set; the second mapping rule is based on the distributed mapping of the PUSCHs, each PUSCH which conflicts with the PUCCH is taken as an independent individual, and symbols contained in each PUSCH are taken as a symbol set to be mapped in each symbol set; the third mapping rule is slot-based distributed mapping, in which symbols corresponding to a PUSCH in which there is a collision with a PUCCH are divided into a plurality of groups, symbols corresponding to a PUSCH transmitted in the same slot (a slot divided by an SCS of the PUSCH) are grouped to form a symbol set, and mapping is performed in each symbol set.

mapping mode 3: mapping the UCI to continuous symbols from a predefined symbol;

Mapping mode 2: mapping is started from a first symbol which is used for transmitting UCI after a first demodulation reference signal (DMRS), and the UCI is mapped to continuous symbols. If there is no DMRS in a certain PUSCH (because of an unavailable symbol, a PUSCH divided by a slot boundary, etc.), mapping is performed based on an assumed DMRS position, where the assumed DMRS position may be the first symbol or the same as the relative position of the DMRS in the previous PUSCH containing the DMRS or the next PUSCH containing the DMRS (for example, the DMRS position in the previous PUSCH is the 3 rd symbol in the symbols contained in this PUSCH, the assumed DMRS in this PUSCH is located in the 3 rd symbol in the symbols contained in this PUSCH). It should be noted that this scheme is preferably applied to the AN and may also be applied to the CSI, and is not particularly limited herein.

wherein, the uniform distribution mode comprises a mode A and/or a mode B;

the mode A comprises the following steps: firstly, X1 symbols which are nearest to the symbols of each group of DMRS are determined and can be used for UCI transmission, if the size of the mapping resource of the UCI does not exceed the total size of UCI carried on X1 symbolsIf the size of the resource is large, taking the X1 symbols as mapping symbols of UCI, and uniformly distributing mapping resources of UCI on the X1 symbols; otherwise, further determining X2 symbols which are nearest to X1 symbols and can be used for UCI transmission, if the size of mapping resources of the UCI does not exceed the total resource size of UCI carried on X1+ X2 symbols, taking the X1+ X2 symbols as the mapping symbols of the UCI, uniformly distributing the resources left after the mapping resources of the UCI are fully mapped on the X1 symbols on the X2 symbols, otherwise, determining X3 symbols which are nearest to X2 symbols and can be used for UCI transmission, and the like until the size of the mapping resources meeting the UCI does not exceed the size of the mapping resources of the UCI

the mode B comprises the following steps: firstly, determining X1 symbols which are nearest to the symbols of each group of DMRS and can be used for UCI transmission, if the size of the UCI mapping resources of 1/X1 does not exceed the size of the UCI-carrying resources on one symbol of X1 symbols, regarding the X1 symbols as the UCI mapping symbols, and uniformly distributing the UCI mapping resources on the X1 symbols; otherwise, further determining X2 symbols of the nearest X1 symbols available for UCI transmission, if the size of the mapping resources of 1/(X1+ X2) UCI does not exceed the resource size of UCI carried on one symbol of X1+ X2 symbols, taking the X1+ X2 symbols as the mapping symbols of UCI, uniformly distributing the mapping resources of UCI on the X1+ X2 symbols, otherwise, determining X3 symbols of the nearest X2 symbols available for UCI transmission, and analogizing until satisfying the requirement of UCI transmission

Does not exceed the size of the mapping resources of the UCI

Uniformly distributed on each symbol;

Determining the total resource size of UCI carried on each symbol

In this embodiment, when the mapping manner 4 is uniformly distributed, one manner is(evenly distributed among each set of DMRS): firstly, determining X1 symbols which are nearest to each group of DMRS symbols (namely 1 symbol before and after each group of DMRS symbols, wherein the front or back of each group of DMRS symbols may not have any symbol, only one side of the symbol is needed), if the size of UCI mapping resources does not exceed the total resource size of UCI carried on X1 symbols, using the X1 symbols as UCI mapping symbols, and uniformly distributing the UCI mapping resources on the X1 symbols; otherwise, further determining X2 symbols which are nearest to X1 symbols and can be used for UCI transmission, if the size of mapping resources of UCI does not exceed the total resource size of UCI carried on X1+ X2 symbols, taking the X1+ X2 symbols as mapping symbols of UCI, uniformly distributing the remaining resources on the X2 symbols after the mapping resources of UCI are mapped on the X1 symbols, otherwise, determining X3 symbols which are nearest to X2 symbols and can be used for UCI transmission, and so on until the size of mapping resources meeting UCI does not exceed the total resource size of all symbols used for carrying UCI, and uniformly distributing the remaining resources on the last determined Xj symbols after the mapping resources of UCI are mapped on the full symbol; another way (evenly distributed over each UCI-bearing symbol): firstly, determining X1 symbols which are nearest to the symbols of each group of DMRS and can be used for UCI transmission, if the size of the mapping resources of 1/X1 UCI does not exceed the size of the resources carrying UCI on one symbol of X1 symbols, using the A1 symbols as the mapping symbols of UCI, and uniformly distributing the mapping resources of UCI on the X1 symbols; otherwise, further determining X2 symbols nearest to X1 symbols available for UCI transmission, if the size of the mapping resources of 1/(X1+ X2) UCI does not exceed the resource size of UCI carried on one symbol of X1+ X2 symbols, taking the X1+ X2 symbols as mapping symbols of UCI, and uniformly distributing the mapping resources of UCI over the X1+ X2 symbols, otherwise, determining X3 symbols nearest to X2 symbols available for UCI transmission, and so on until satisfying X3832 symbols nearest to X1 symbols

Does not exceed the size of the mapping resources of the UCI

Evenly distributed over the symbols.

When the mapping mode 4 is forward distribution, starting from the 1 st group of DMRS symbols (DMRS with the earliest time), the nearest adjacent 1 symbol before and after the group of DMRS symbols, which can be used to carry UCI, are taken to form a1 symbols (a1 may be less than or equal to 2, because there may be no symbol before the DMRS, or there may be no symbol after the DMRS), if the size of the mapping resource of the UCI does not exceed the total resource size carrying the UCI over the a1 symbols, determining the A1 symbols as mapping symbols of UCI, otherwise, taking the nearest adjacent 1 symbol before and after a group of DMRS to form A2 symbols, if the size of the mapping resources for UCI does not exceed the total resource size for carrying UCI over the a1+ a2 symbols, determining the a1+ a2 symbols as mapping symbols of UCI, and so on, until the size of mapping resources satisfying UCI does not exceed the total resource size over all symbols that have been determined to carry UCI; after the last group of DMRS symbols is subjected to the operations, the size of the mapping resource which still can not meet the UCI does not exceed the total resource size on all the determined symbols for carrying the UCI, starting from the first group of DMRS, the nearest B1 symbols which are before and after the A1 symbols corresponding to the group of DMRS symbols and can be used for carrying the UCI are taken, if the size of the mapping resource of the UCI does not exceed the total resource size on all the determined symbols for carrying the UCI, the method comprises the steps of

Determining the total resource size of UCI carried on each symbol

Taking one symbol as a mapping symbol of UCI, otherwise, obtaining B2 symbols for the next group of DMRS, and so on, until the size of the mapping resource satisfying the UCI does not exceed the size of the mapping resource determined for carrying the UCIThe total resource size over all symbols.

In this embodiment, it should be noted that the size of the mapping resource of the UCI corresponding to each symbol set may be determined through two processing manners. The first processing mode is as follows: the UCI information is divided into a plurality of groups, each group corresponds to a symbol set, and the mapping resource size of the UCI corresponding to each symbol set is determined in each symbol set based on the corresponding UCI information. When the UCI information is grouped, the UCI information can be uniformly grouped (when the UCI information is not an integral multiple, a certain group or a plurality of groups contain more information), or the UCI information can be grouped according to a proportion; the ratio may be obtained from the ratio of each symbol set in a total symbol set, which is a symbol set made up of symbols corresponding to a PUSCH in which there is a collision with a PUCCH. The second processing mode is as follows: determining the size of the total UCI mapping resources based on symbols contained in all PUSCHs overlapped with a PUCCH by taking UCI information as a whole, dividing the size of the total UCI mapping resources into a plurality of groups, wherein each group corresponds to one symbol set, and thus obtaining the size of the UCI mapping resources corresponding to each symbol set. When the mapping resource sizes corresponding to the total UCI are grouped, the mapping resource sizes can be uniformly grouped (when the mapping resource sizes are not integer multiples, a certain group or a plurality of groups contain more information), or the mapping resource sizes can be grouped according to a proportion; the ratio may be obtained according to a ratio of each symbol set in a total symbol set, which is a symbol set made up of symbols corresponding to a PUSCH in which a PUCCH has a collision.

Based on the content of the above embodiment, in the present embodiment, for processing mode 1, when grouping UCI information, grouping is performed uniformly or grouping is performed in proportion; the proportion is obtained according to the proportion of each symbol set in a total symbol set, wherein the total symbol set is a symbol set formed by symbols corresponding to PUSCH with conflict with PUCCH.

In this embodiment, it should be noted that the symbols that can be used for UCI transmission include: symbols not carrying DMRS, or determined from the waveform: when the OFDM waveform is adopted, the DMRS symbol is a symbol that does not carry the DMRS, and a DMRS symbol that has a resource element RE (resource element) that can be used to carry a TB (that is, the DMRS on this DMRS symbol is mapped to a part of REs at intervals, and the remaining REs can be used for TB transmission, and the remaining REs are considered to also be able to transmit UCI).

In this embodiment, it should be noted that the UCI is at least one of HARQ-ACK, CSI, and SR; different UCI types may select the same or different mapping rules as described above, and are not particularly limited herein.

The present application will be specifically described below with reference to specific examples.

The first embodiment:

in this embodiment, the PUCCH and the PUSCH have the same SCS, and one TB is transmitted in 2 slots through the PUSCH, where this TB is coded based on the total symbol number corresponding to the PUSCH in 2 slots as shown in fig. 7 to 14 (specifically, the total resource or total RE number that can be used for TB transmission in the total symbol number and the modulation mode corresponding to the MCS are taken to determine the number of bits after coding), where how to determine the number of symbols occupied by the PUSCH in each slot does not belong to the protection range of the present application (refer to other inventions or the prior art), and the present application assumes that the transmission symbols corresponding to the PUSCH in 2 slots are known; in a slot n, if a PUCCH1 carrying HARQ-ACK sequence 1 overlaps with a PUSCH carrying a multi-slot TB in a time domain, it is determined that the HARQ-ACK sequence 1 carried on the PUCCH1 is transferred to the slot 1 and transmitted on the PUSCH, here, taking a PUSCH formed by continuous symbols in the figure as an independent PUSCH as an example, 2 PUSCHs exist in the slot n, and a PUSCH exists in the slot n + 1;

when the mapping mode 1 of the mapping rule 1 is adopted: taking symbols corresponding to a plurality of PUSCHs overlapped with a PUCCH1 in a slot n as an integral set, wherein UCI is mapped in a mode of frequency domain first and time domain later by starting with a first symbol; taking symbols corresponding to 1 PUSCH overlapped with the PUCCH2 in the slot n +1 as an integral set, wherein the UCI is mapped in a frequency domain first and then time domain mode starting with the first symbol; as shown in fig. 7;

when the mapping method 2 of the method mapping rule 1 is adopted: taking symbols corresponding to a plurality of PUSCHs overlapped with a PUCCH1 in a slot n as an integral set, wherein UCI is mapped in a manner of frequency domain first and time domain later by starting with a first symbol after a first DMRS symbol; taking symbols corresponding to 1 PUSCH overlapping with PUCCH2 in slot n +1 as an overall set, where UCI is mapped in a frequency domain first and time domain later starting with the first symbol after the first DMRS symbol, as shown in fig. 8;

when the mapping method 3 of the method mapping rule 1 is adopted: given any one starting symbol, e.g., the first symbol, the mapping is as in FIG. 7; or the first symbol available for UCI transmission after the first DMRS, the mapping scheme is as in fig. 8; other given initial symbol positions are not excluded, the mapping mode is similar, only the mapped initial symbol is influenced, and the description is omitted;

when the mapping method 4 of the method mapping rule 1 is adopted: taking symbols corresponding to a plurality of PUSCHs overlapping with the PUCCH1 in slot n as an overall set, in which UCI is mapped on symbols around DMRS symbols; taking symbols corresponding to 1 PUSCH overlapping with PUCCH2 in slot n +1 as an overall set, where UCI is mapped on symbols around DMRS symbols; when a time domain-frequency domain mapping mode is adopted, the time domain-frequency domain mapping mode may be as shown in fig. 9 (uniformly distributed over all UCI symbols) or as shown in fig. 10 (uniformly distributed among each group of DMRSs, wherein the sizes of UCI resources mapped over symbols for transmitting UCI around the DMRSs are different, it is first determined whether the resources are sufficient for the nearest symbols on both sides of the DMRSs, and if not, it is then determined that symbols next to the DMRSs (symbols spaced by 1 symbol from the DMRS symbols) are used as mapping symbols for the UCI, wherein for mapping resources remaining after removing the UCI transmission resources on the symbols closest to the DMRSs, it may be uniformly mapped over 2 symbols next to both sides of the DMRSs, as shown in fig. 10, or it may be mapped on 1 symbol next to one side of the DMRSs, for example, the preceding symbol, or the following symbol is shown in fig. 11); when a frequency domain-first-time domain mapping manner is adopted, the mapping manner may be as shown in fig. 12 or fig. 13 (where a symbol not mapped with full UCI in fig. 12 may also be a second adjacent symbol before the DMRS group, and in the figure, the second adjacent symbol after the DMRS is taken as an example, fig. 13 is to uniformly distribute mapping resources remaining after removing resources on the UCI-bearing symbol closest to the DMRS on two second adjacent symbols before and after the first group of DMRS, and not allocate the remaining mapping resources to the second adjacent symbol of the second group of DMRS);

when the mapping rule 2 is adopted, the HARQ-ACKs on the PUCCH in the slot n are uniformly distributed in each PUSCH overlapped with the PUCCH, and the other PUCCH2 in the slot n +1 is only overlapped with one PUSCH in the slot n +1 and is only mapped to the one PUSCH; for example, if mapping method 1 of specific mapping and combining method mapping rule 1 is used, as shown in fig. 14, for example, if mapping method 4 of specific mapping and combining method mapping rule 1 is used, as shown in fig. 9-13 (in combination with other methods, only the symbol position mapped by UCI on each PUSCH is affected, for example, mapping method 2 of combining method mapping rule 1, the starting position becomes the first symbol after DMRS of each PUSCH);

when the mode mapping rule 3 is adopted, two PUSCHs in the time slot n are taken as a whole, and the condition of the time slot n +1 is consistent with the mapping rule 2; for example, specifically mapping manner 1 combined with mapping rule 1, as shown in fig. 7, for example, combining mapping manner 4 combined with specific mapping rule 1, as shown in fig. 3-13 (combining other manners to affect only the symbol position mapped by UCI on each PUSCH, such as combining mapping manner 2 of mapping rule 1, the starting position becomes the first symbol after DMRS of each PUSCH);

second embodiment:

in this embodiment, the PUCCH and the PUSCH have different SCS, for example, the SCS of the PUCCH is smaller, and one PUCCH transmitted in one PUCCH slot may overlap with the PUSCH transmitted in multiple PUSCH slots in time domain; it is assumed that a TB is transmitted through PUSCH in 4 slots, where the TB is coded based on the total number of symbols corresponding to PUSCH in 4 slots as shown in fig. 16 (when specifically coding, the total number of resources or total REs available for TB transmission in the total number of symbols is taken, and the number of bits after coding is determined according to the modulation scheme corresponding to MCS), how to determine the number of symbols occupied by PUSCH in each slot does not belong to the protection scope of the present invention (refer to other inventions or prior art), and the present application assumes that the transmission symbols corresponding to PUSCH in 2 slots are known; in PUCCH slot n, there is an overlap in time domain between one PUCCH1 carrying HARQ-ACK sequence 1 and the PUSCH carrying multi-slot TB transmitted in PUSCH slots 2n and 2n +1, and it is determined that HARQ-ACK sequence 1 carried on PUCCH1 is transferred to PUSCH overlapping with PUCCH in PUSCH slots 2n and 2n +1 for transmission, here taking one PUSCH in one PUSCH slot as an example (instead of regarding symbols occupied by all PUSCH transmissions in 4 slots as a whole PUSCH); then:

when the mapping mode 1 of the mapping rule 1 is adopted: taking symbols corresponding to a plurality of PUSCHs overlapped with the PUCCH1 in the

PUSCH slots

2n and 2n +1 as an integral set, and mapping UCI in a frequency domain first and time domain second mode starting from the first symbol; as shown in fig. 15;

when the mapping mode 2 of the mapping rule 1 is adopted: taking symbols corresponding to a plurality of PUSCHs overlapped with a PUCCH1 in

PUSCH slots

2n and 2n +1 as an integral set, wherein UCI is mapped in a manner of frequency domain first and time domain later by starting with a first symbol after a first DMRS symbol; as shown in fig. 16;

when the mapping mode 3 of the mapping rule 1 is adopted: given any one starting symbol, e.g., the first symbol, the mapping is as in fig. 15; or the first symbol available for UCI transmission after the first DMRS, the mapping scheme is as shown in fig. 16; other given initial symbol positions are not excluded, the mapping mode is similar, only the initial symbol of the mapping is influenced, and the description is omitted;

when the mapping mode 4 of the mapping rule 1 is adopted: taking symbols corresponding to a plurality of PUSCHs overlapping with the PUCCH1 in the PUSCH slots 2n and 2n +1 as an overall set, where UCI is mapped on symbols surrounding DMRS symbols; when the time domain-to-frequency domain mapping manner is adopted, as shown in fig. 17 (the symbols are uniformly distributed over all UCI symbols, since the total UCI transmission symbols assumed in this embodiment are 5 symbols, one of the symbols is not occupied in the frequency domain, and at least 8 symbols closest to the DMRS exist around the DMRS, so that the symbols distributed over 8 symbols are not occupied, and the symbols do not need to be mapped to symbols next to the DMRS); when the mapping mode of first frequency domain and then time domain is adopted, the mapping mode can be as shown in fig. 18 or fig. 19; fig. 18 is a diagram that, according to the order of DMRS groups, first selects 2 symbols closest to both sides of each DMRS group for mapping, and when UCI resources on these symbols cannot meet the mapping resources required by UCI, then determines 2 symbols closest to both sides of the next DMRS group as UCI mapping symbols, and so on, if the 2 symbols on both sides of the DMRS are not occupied, then the symbols closest to the front (adjacent to the front of the DMRS) may be selected to be occupied first, the remaining resources are mapped to the symbols closest to the back (adjacent to the back of the DMRS), and if the 1 symbol of the 2 symbols on both sides of the DMRS is occupied less than, then the symbols closest to the front may be mapped (the DMRS may also be approximately determined as the next symbol); in fig. 19, the closest 1 symbol (may be the former symbol, i.e., the closest symbol in front of the DMRS, or the latter symbol, i.e., the closest symbol behind the DMRS) on one side of each group of DMRSs is first selected and mapped, and when resources are insufficient, the mapped symbols further around the second group of DMRSs are used to determine UCI;

when mapping rule 2 is adopted, HARQ-ACKs on PUCCH1 are evenly distributed in each PUSCH in

slots

2n and 2n +1 overlapping with PUCCH; for example, if mapping scheme 1 combined with mapping rule 1 is specifically mapped, as shown in fig. 20, for example, if mapping scheme 4 combined with mapping rule 1 is specifically mapped, as shown in fig. 21 (for example, in combination with other schemes, only the symbol position mapped by UCI on each PUSCH is affected, for example, in combination with mapping scheme 2 of mapping rule 1, the starting position becomes the first symbol after DMRS of each PUSCH);

when the mapping rule 3 is adopted, two PUSCHs in the

time slots

2n and 2n +1 are taken as a whole; for example, if mapping mode 1 of mapping rule 1 is specifically mapped, as shown in fig. 15, for example, if mapping mode 2 of mapping rule 1 is combined, as shown in fig. 15, for example, if mapping mode 4 of mapping rule 1 is combined, as shown in fig. 16-18 (in combination with other modes, only the symbol position mapped on each PUSCH by UCI is affected).

It should be noted that, in the second embodiment, if there is still one PUCCH2 in slot n +1 and there is an overlap with the PUSCH in slot 2n +1 and/or slot 2n +2, the processing manner is similar to the above, and details are not repeated.

In the first and second embodiments, the PUSCH carrying the TB may be a single PUSCH in multiple slots as a whole, which means that all symbols corresponding to the PUSCH in slot n and slot n +1 in embodiment 1 are included in a PUSCH which collides with the PUCCH1, and all symbols corresponding to the PUSCH in

slot

2n, 2n +1, 2n +2, 2n +3 in the second embodiment are included in a PUSCH which collides with the PUCCH1, and thus a specific mapping method is similar to mapping method 1 of mapping rule 1 to mapping method 4 of mapping rule 1 described above, except that the above symbol set is replaced, for example, when the mapping method 4 of mapping rule 1 is executed, symbols around DMRS symbols in slot n +1 are also involved in UCI mapping in the first embodiment, and symbols around DMRS symbols in slots 2n +2 and 2n +3 are also involved in UCI mapping in the second embodiment, as shown in fig. 22;

in the above embodiment, both the terminal and the base station may determine which symbols the UCI is mapped to in the same manner, the terminal side performs UCI mapping and transmission according to the mapping rule, and the base station side acquires UCI information from the corresponding symbols in the received PUSCH according to the mapping rule.

a receiving module 11, configured to receive uplink control information UCI in a target PUSCH when a physical uplink shared channel PUSCH carrying a multi-slot transport block TB and a physical uplink control channel PUCCH have a collision in a time domain; and the target PUSCH is a PUSCH which conflicts with the PUCCH or all PUSCHs which correspond to the same TB in a time slot in which the PUSCH which conflicts with the PUCCH is positioned.
