Detailed Description
The following description of the technical solutions in the embodiments of the present application will be made clearly and completely with reference to the accompanying drawings in the embodiments of the present application, and it is apparent that the described embodiments are only some embodiments of the present application, but not all embodiments. All other embodiments, which can be made by one of ordinary skill in the art without undue burden from the present disclosure, are within the scope of the present disclosure.
It should be noted that, in the prior art, as shown in fig. 1, PUSCH supports only one retransmission method in R15, that is, retransmission based on time slots. Specifically, the higher layer signaling (for example, PUSCH-aggregation factor) configures in advance the number of repeated transmissions (also called Aggregation factor, for simplicity, N), where N repeated transmissions indicate that the PUSCH occupies N time slots for transmission, and the same TB information is transmitted on the same PUSCH resource in each time slot. The time domain position of PUSCH transmission in this time slot is determined according to the same initial symbol and symbol number in each time slot, if the symbol set determined according to the initial symbol and symbol number in one time slot contains downlink symbols configured by higher layer signaling (such as tdd-UL-DL-configuration command, ortd-UL-DL-configuration de-directed), it is determined that this symbol set is not available, PUSCH is not transmitted in this time slot, but one repetition transmission is recorded, that is, if the symbol set determined in N1 time slots in N time slots is not available, only N-N1 repetition transmissions are actually performed. The PUSCH extends the repetition transmission in the above R15 to a certain extent in R16, besides the pre-configuration of the repetition number by the higher layer signaling, a list of information is added to the TDRA table to express the repetition number (configured by the repetition number-R16), and the downlink control information DCI (Downlink Control Information) (the DCI for scheduling the PUSCH or the physical downlink control channel PDCCH (Physical Downlink Control Channel) is called UL grant, the DCI and the PDCCH may be considered equivalent in terms of describing the scheduling and information indication, the DCI is a format specifically used for the PDCCH transmission, and the PDCCH is a channel for carrying the DCI) is selected from the table of time domain resource allocation TDRA (Time Domain Resource Allocation), and the relevant information (such as the start and length indication value SLIV (Start and length indicator value) (the information of the start symbol and the number of transmission symbols)) of the time domain resource and K2 (scheduling timing) are indicated to the terminal, so as to implement dynamic change of the repetition transmission number, which is called repetition type A. In addition, repetition type B is supported, that is, the transmission opportunity (i.e. the time domain resource, which is embodied as the symbol set) of each repetition is determined according to the number of transmission symbols according to the start symbols indicated in the PDCCH (or DCI) for scheduling PUSCH, and the number of repeated transmission can be obtained in a manner similar to repetition type A; the time domain resource of the first repetition 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 repetition is sequentially determined after the first repetition. Specifically, each transmission opportunity corresponds to the same number of symbols, the starting point is the first symbol after the previous repetition, and thus N consecutive repetition transmission opportunities are obtained by dividing, where each transmission opportunity becomes a nominal repetition (Nominal repetition, i.e. repetition divided according to the configuration parameters, but not necessarily the actual transmission). If a set of symbols corresponding to Nominal repetition contains DL symbols or SSB symbols or unavailable symbols of higher layer signaling configuration or spans a slot boundary, the Nominal repetition is divided into a plurality of actual repetitions (Actual repetition, i.e., repetition of actual transmission), and each Actual repetition contains only symbols that can be used for uplink transmission, such as uplink symbols or Flexible symbols. The repetition PUSCHs may be in the same time slot or may be distributed in different time slots. As particularly shown in fig. 1. For Actual repetition where the transmission length (number of symbols) obtained in the process of Nominal to Actual partitioning is relatively short, e.g., actual repetition of 1 symbol, such Actual repetition is not transmitted unless the transmission length of the scheduling signaling configuration is 1 symbol. For each Actual repetition, the DMRS mapping rule determines the DMRS symbol position according to the mapping manner in one PUSCH in the prior art.
In the prior art, as shown in fig. 2, for the same terminal, in order to avoid the occurrence of excessive power Peak-to-average ratio PARR (Peak-to-Average Power Ratio), simultaneous transmission of PUCCH and PUSCH is not supported, so when time domain resources between PUCCH and PUSCH overlap, the terminal may multiplex UCI for transmission on PUSCH, so that PUCCH does not need to be transmitted, or a higher priority channel transmission is selected based on physical layer priority, and a low priority channel is not transmitted. When there is a collision (so-called collision, which may be overlapping 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 following explanation is made) in one or more slots in PUSCH of the same physical layer priority (including single slot and retransmission) and single slot PUCCH (without retransmission), the terminal multiplexes UCI carried by PUCCH on all PUSCHs overlapping with PUCCH for single slot PUSCH or PUSCH for retransmission. For the PUSCH repeatedly transmitted by using repetition Type-B, the terminal multiplexes UCI carried by the PUCCH on a real (actual) PUSCH overlapping with the PUCCH and having a first symbol number greater than 1. When there is a collision between resources of PUSCH (including single slot and repeat transmission) and multi-slot PUCCH (i.e. with repeat transmission) of the same physical layer priority, the PUSCH channel is discarded in the collided slot, and only PUCCH is transmitted. When the PUCCH and PUSCH resources with different physical layer priorities conflict, the channel with lower priority is discarded, and only the channel with higher priority is transmitted. At present, both HARQ-ACK and CSI carried by PUCCH can be transmitted through PUSCH, if SR exists on PUCCH, unless PUSCH is PUSCH carrying only Semi-persistent channel state information SP-CSI (Semi-persistent CSI), PUSCH is discarded at this time, SR is discarded. When the number of HARQ-ACK bits is not more than 2, the HARQ-ACK performs punching transmission on the PUSCH (namely, the TB is always encoded according to the resources based on the PUSCH under the condition of no HARQ-ACK, and when the HARQ-ACK is mapped, the data in the corresponding position is punched out, namely, the data is covered); when the number of HARQ-ACK bits is greater than 2, the HARQ-ACK performs rate-matched transmission on the PUSCH (i.e., when the TB or CSI on the PUSCH is encoded, the resources on the PUSCH for HARQ-ACK transmission are removed and the encoding is based on the remaining resources on the PUSCH). The CSI and the TBs on PUSCH are always rate matched transmitted. Both HARQ-ACK and CSI are mapped for transmission on all layers corresponding to TBs on PUSCH. The HARQ-ACK is mapped starting from the first non-DMRS symbol after the first DMRS on PUSCH. When the number of HARQ-ACK bits is not more than 2, a part of resources is reserved. When the HARQ-ACK bit is 0,1 or 2, the HARQ-ACK resource reservation is always carried out according to 2 bits, and if the actual HARQ-ACK is 1 bit, the HARQ-ACK resource reservation is mapped on a part of resources in the reserved resources. Mapping CSI from a first non-DMRS symbol on a PUSCH, when the information bit of the HARQ-ACK is smaller than 2, reserving resources of the HARQ-ACK exist on the PUSCH, the CSI part 1 is not mapped on the reserving resources, and the CSI part 2 and the TB can be mapped on the reserving resources; if the information bit of the HARQ-ACK is greater than 2, then neither CSI part 1, CSI part 2, nor TB will map on the HARQ-ACK resources. The UCI performs frequency domain discrete mapping within the transmission bandwidth of PUSCH in order of frequency domain first and then timing. For a certain UCI type, the interval d between modulation symbols on one OFDM symbol is determined as follows: d=1 if the number of modulation symbols remaining unmapped by the UCI is greater than or equal to the number of REs available on the current OFDM symbol; otherwise d=floor (the number of REs available on the current OFDM symbol/the number of modulation symbols remaining unmapped by UCI), floor is rounded down. As shown in fig. 3, the collision refers to a collision in the same carrier Group, for example, a primary carrier Group MCG (Master (primary) Cell Group) and a secondary carrier Group SCG (Secondary Cell Group) in dual link are each a carrier Group when a carrier Group, for example, a supporting PUCCH, transmits on an SCG, and a primary PUCCH Group (Primary PUCCH Group) and a secondary PUCCH Group (Secondary PUCCH Group) occur, where each PUCCH Group is a carrier Group.
For the current R17 positioning method, coverage enhancement is proposed (Coverage enhancement) because complex environments or interference at cell edges may affect the coverage of signal or channel transmissions. In addition, in order to reduce the cost and size of a New wireless NR (New RAT) terminal, and better adapt to the requirements of wearable devices and the like, a terminal with reduced complexity (RedCap terminal) is proposed, and for such a terminal, transmission performance may be reduced due to reduction of complexity and hardware index, such as bandwidth and antenna, and a certain coverage enhancement is required to compensate for the reduction of transmission performance.
As shown in fig. 4, for a terminal that needs coverage enhancement, the prior art is researching a method of processing TB (TB processing over multiple slots) across multiple slots (slots), hereinafter abbreviated as multi-slot TB transmission. The transmission of multi-slot TBs on PUSCH is different from PUSCH retransmission in the prior art, in which PUSCH may occupy multiple slots for transmission, but each slot is a repeated transmission of the same TB, i.e. each TB is encoded based on PUSCH resources in one slot, and then is repeatedly transmitted in each slot, and each slot is a separate PUSCH transmission. In the method for processing the time slot TB, one TB is coded based on the total PUSCH resources in a plurality of time slots, namely the TB is coded in a joint way based on a plurality of time slots, and the TB is not coded in an independent way in each time slot; it is understood that "one TB is transmitted in a plurality of PUSCHs among a plurality of slots, each of which carries a part of the encoded TB", and "one TB is transmitted in one PUSCH, but the length of the PUSCH spans a plurality of slots". Fig. 4 gives an example of a repetition type a and cross-slot TB transmission comparison, where the TBs is both the transport block Size (TB Size). Through multi-time slot TB transmission, the coding rate can be reduced, the code length of the codes can be increased, thus improving the coding performance and equivalently enhancing the coverage. However, for the case of multi-slot TB transmission in PUSCH, if a PUCCH-PUSCH collision occurs, there is currently no clear solution. In order to solve the problem, the embodiment of the application provides an information transmission method, which transfers uplink control information UCI on a physical uplink shared channel PUSCH carrying a multi-slot transport block TB to a target PUSCH to be transmitted when there is a conflict between the physical uplink shared channel PUSCH carrying the multi-slot transport block TB and the physical uplink control channel PUCCH in the time domain, so that UCI is normally transmitted on the PUSCH carrying the multi-slot TB, UCI discarding is avoided, and transmission performance of a system is improved.

The present application is specifically described below.
As shown in fig. 5, a step flow chart of an information transmission method applied to a terminal device according to an embodiment of the present application is provided, where the method includes the following steps:
step 101: when a conflict exists between a physical uplink shared channel PUSCH carrying a multi-slot transport block TB and a physical uplink control channel PUCCH in the time domain, transferring uplink control information UCI on the PUCCH to a target PUSCH for transmission; the target PUSCH is a PUSCH having a collision with the PUCCH or is all PUSCHs corresponding to the same TB in a slot where the PUSCH having a collision with the PUCCH is located.
In this step, for the physical uplink shared channel PUSCH carrying the multi-slot transport block TB, when there is a collision with the physical uplink control channel PUCCH in the time domain, uplink control information UCI on the PUCCH is transferred to the target PUSCH for transmission, where the target PUSCH is the PUSCH having a collision with the PUCCH or is all PUSCHs corresponding to the same TB in the slot in which the PUSCH having a collision with the PUCCH is located. For example, if a PUSCH carrying a multi-slot TB is referred to as one PUSCH in a plurality of slots, meaning that a part of symbols of the PUSCH in a certain slot collide with the PUCCH, UCI may be transferred to be transmitted on the one PUSCH transmitted in a plurality of slots; if the PUSCH carrying a multi-slot TB is referred to as an independent PUSCH in each slot, the PUSCH where there is a collision is a certain independent PUSCH and no other PUSCHs are 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 transmission block TB and the physical uplink control channel PUCCH collide in the time domain, uplink control information UCI on the PUCCH is transferred to the target PUSCH to be transmitted, and when the PUCCH collides with the PUSCH, UCI on the PUCCH can be transferred to the target PUSCH to be transmitted, UCI discarding is avoided, and the transmission performance of the system is improved.
Based on 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 conflict between the PUSCH carrying the multi-slot transport block TB and the PUCCH in the time domain, UCI of the PUCCH is mapped onto the target PUSCH according to a predetermined mapping rule. The predetermined mapping rule includes:
mapping rule 1: taking a symbol contained in the PUSCH which has conflict with the PUCCH as a symbol set, and mapping in the symbol set;
mapping rule 2: taking each PUSCH which has conflict with the PUCCH as an independent individual, taking a symbol contained in each PUSCH as a symbol set, and mapping in each symbol set;
mapping rule 3: and dividing symbols corresponding to the PUSCH which has conflict with the PUCCH into a plurality of groups, taking the symbols corresponding to the PUSCH transmitted in the same time slot as a group, forming a symbol set, and mapping in each symbol set.
Based on the content of the above embodiment, in this embodiment, the predetermined mapping rule includes at least one of the following:
Mapping rule 1: taking a symbol contained in the PUSCH which has conflict with the PUCCH as a symbol set, and mapping in the symbol set;
mapping rule 2: taking each PUSCH which has conflict with the PUCCH as an independent individual, taking a symbol contained in each PUSCH as a symbol set, and mapping in each symbol set;
mapping rule 3: and dividing symbols corresponding to the PUSCH which has conflict with the PUCCH into a plurality of groups, taking the symbols corresponding to the PUSCH transmitted in the same time slot as a group, forming a symbol set, 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 the symbols contained in the PUSCH having a conflict with the PUCCH are used as a symbol set, and mapping is performed in the symbol set; the second mapping rule is a PUSCH-based dispersion mapping, wherein each PUSCH having a collision with the PUCCH is used as an independent entity, the symbols contained in each PUSCH are used as a symbol set, and mapping is performed in each symbol set; the third mapping rule is a dispersion mapping based on time slots, dividing symbols corresponding to PUSCH having collision with PUCCH into a plurality of groups, forming one symbol set by using symbols corresponding to PUSCH transmitted in the same time slot (time slot divided by SCS of PUSCH) as a group, and mapping each symbol set.
Based on the above embodiments, in this embodiment, the UCI is at least one of HARQ-ACK, CSI, SR.
In this embodiment, it should be noted that the UCI is at least one of HARQ-ACK, CSI, SR; different UCI types may select the same or different mapping rules as described above, without specific limitation. Wherein, hybrid automatic repeat request acknowledgement HARQ-ACK (HARQ-ACK, hybrid Automatic Repeat request-ACKnowledgment) is a generic term for ACK and NACK feedback information, and subsequent HARQ-ACKs are 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 conforming set, at least one of the following mapping modes is included:
mapping mode 1: mapping from a first symbol available for transmitting UCI, mapping the UCI onto consecutive symbols;
mapping method 2: mapping from a first symbol available for transmitting UCI after a first demodulation reference signal DMRS, mapping the UCI onto consecutive symbols;
mapping method 3: mapping from a predefined symbol, mapping the UCI onto consecutive symbols;
Mapping method 4: and mapping around each DMRS symbol, and determining one of the front and rear DMRS in the symbol set or symbols adjacent to the DMRS, which can be used for UCI transmission, as a mapping symbol of UCI.
In this embodiment, it should be noted that, for three mapping rules of UCI on a target PUSCH, four mapping methods are included when mapping is performed in a symbol set, where the mapping methods are respectively as follows:
mapping mode 1: mapping is started from the first symbol available for transmitting UCI, and UCI is mapped onto consecutive symbols (how many resources are occupied by the UCI is pre-calculated, and all resources occupied by the UCI are mapped, and the explanation is omitted. It should be noted that this method is preferably applied to the channel state information CSI, but may also be applied to the AN, and is not particularly limited herein.
Mapping method 2: the UCI is mapped onto consecutive symbols starting from the first symbol available for transmission of UCI after the first demodulation reference signal DMRS. 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 a presumed DMRS position, where the presumed DMRS position may be the first symbol, or the same relative position as the DMRS in a previous PUSCH containing the DMRS or a subsequent PUSCH containing the DMRS (e.g., the DMRS position in the previous PUSCH is the 3 rd symbol among the symbols contained in the PUSCH, the presumed DMRS in the PUSCH is the 3 rd symbol among the symbols contained in the PUSCH). Note that this method is preferably applied to AN, but may also be applied to CSI, and is not particularly limited here.
Mapping method 3: the UCI is mapped to consecutive symbols starting from a predefined one symbol.
Mapping method 4: and mapping around each DMRS symbol, determining one of the front and rear DMRS or symbols adjacent to the DMRS in the symbol set, which can be used for UCI transmission (namely, when the DFT-s-OFDM is spread spectrum orthogonal frequency division multiplexing based on discrete Fourier transform, the symbols of either the DMRS symbol or the symbols which can be used for UCI transmission are used as mapping symbols of UCI, when the OFDM is orthogonal frequency division multiplexing, besides the symbols which are not used for the DMRS transmission, if RE which can be used for TB transmission exists on the symbols used for the DMRS transmission, the symbols used for the DMRS transmission can also be used as the symbols used for carrying UCI transmission). 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 UCI around each group of DMRS differs by no more than 1 symbol, and when the number of the mapping symbols of UCI around different groups of DMRS is different, more mapping symbols of UCI exist around the previous DMRS group; or the mapping symbols of these UCI are preferentially distributed over the symbols available for UCI transmission around the preceding DMRS group.
Based on the content of the above embodiment, in the present embodiment, for mapping mode 2:
if the DMRS does not exist in a certain PUSCH, mapping is performed based on the assumed DMRS position; wherein the assumed DMRS position is the first symbol, or the same symbol as the relative position of the DMRS in the previous PUSCH including the DMRS or the next PUSCH including the DMRS.
In this embodiment, it should be noted that, with mapping mode 2, if there is no DMRS in a certain PUSCH (because of an unavailable symbol, a PUSCH that is obtained by dividing a slot boundary, etc.), mapping is performed based on a assumed DMRS position, where the assumed DMRS position may be the first symbol, or the same relative position as the DMRS in the previous PUSCH containing the DMRS or the subsequent PUSCH containing the DMRS (for example, the DMRS position in the previous PUSCH is the 3 rd symbol in the symbols contained in the PUSCH, the assumed DMRS in the PUSCH is the 3 rd symbol in the symbols contained in the PUSCH). Note that this method is preferably applied to AN, but may also be applied to CSI, and is not particularly limited here.
Based on the content of the above embodiment, in the present embodiment, the mapping mode 4 includes:
Dividing the DMRS symbols into N groups, wherein the DMRS symbols in each group are adjacent, the DMRS symbols in different groups are not adjacent, and the number phase difference value of the mapping symbols of UCI around each group of the DMRS is lower than a preset value; n is an integer greater than 0; when the number of mapping symbols of UCI around different DMRS groups is different, more mapping symbols of UCI exist around the previous DMRS group, or the mapping symbols of UCI are preferentially distributed on symbols available for UCI transmission around the previous DMRS group.
In this embodiment, for mapping mode 4, DMRS symbols may be divided into N groups, DMRS symbols in each group are adjacent, DMRS symbols in different groups are not adjacent, and the mapping symbols of these UCI may be distributed around each group of DMRS as uniformly as possible, that is, the number of mapping symbols of UCI around each group of DMRS differs by no more than 1 symbol, and when the number of mapping symbols of UCI around different groups of DMRS is different, there are more mapping symbols of UCI around the preceding DMRS group; or the mapping symbols of these UCI are preferentially distributed over the symbols available for UCI transmission around the preceding DMRS group.

Wherein the uniform distribution mode comprises a mode A and/or a mode B;
the mode a includes: firstly, determining X1 symbols which are nearest to symbols of each group of DMRS 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 the X1 symbols, taking the X1 symbols as mapping symbols of UCI, and uniformly distributing the mapping resources of UCI on the X1 symbols; otherwise, further determining the nearest neighborX2 symbols which are near to X1 symbols and can be used for UCI transmission, if the size of the mapping resources of 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 UCI, uniformly distributing the residual resources after the mapping resources of UCI are mapped to the X1 symbols on the X2 symbols, otherwise, determining X3 symbols which are nearest to the X2 symbols and can be used for UCI transmission, and analogically processing until the size of the mapping resources of UCI is satisfied and does not exceedThe total resource size on each symbol for carrying UCI, mapping UCI mapping resource to full +.>After the symbols, uniformly distributing the rest resources on the finally determined Xj 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 by two processing methods. The first processing mode is as follows: dividing UCI information into a plurality of groups, wherein each group corresponds to one symbol set, and determining the mapping resource size of UCI corresponding to each symbol set based on the corresponding UCI information in each symbol set. Wherein, when the UCI information is grouped, it may be uniformly grouped (a certain group or groups contain more information when not an integer multiple), or be proportionally grouped; the ratio may be obtained from a ratio of each symbol set in a total symbol set, which is a symbol set composed of symbols corresponding to PUSCH where there is a collision with the PUCCH. The second processing mode is as follows: and taking the UCI information as a whole, determining the mapping resource size of the total UCI based on the symbols contained in all PUSCHs overlapped with the PUCCH, dividing the mapping resource size of the total UCI into a plurality of groups, wherein each group corresponds to one symbol set, and thus obtaining the mapping resource size of the UCI corresponding to each symbol set. Wherein, when the mapping resource size corresponding to the total UCI is grouped, the mapping resource size may be uniformly grouped (a certain group or groups contain more information when not an integer multiple), or may be grouped according to a proportion; the ratio may be obtained from a ratio of each symbol set in a total symbol set, which is a symbol set composed of symbols corresponding to PUSCH where there is a collision with the PUCCH.

In this embodiment, it should be noted that, in processing mode 1, UCI information may be grouped uniformly (a group or groups contain more information when not an integer multiple), or may be grouped according to a proportion; the ratio may be obtained from a ratio of each symbol set in a total symbol set, which is a symbol set composed of symbols corresponding to PUSCH where there is a collision with the PUCCH.

In this embodiment, after the mapping symbols are determined, on each symbol, the mapping may be performed continuously or discretely in order from low frequency to high frequency or from high frequency to low frequency in the frequency domain.
Based on the foregoing embodiments, in this embodiment, the symbols that may be used for UCI transmission include: symbols not carrying DMRS;
alternatively, the determination is based on the waveform: when the OFDM waveform is used, the symbol is not carried with DMRS and the DMRS symbol with resource element RE for carrying TB are used, and when the DFT-s-OFDM waveform is used, the symbol is not carried with DMRS.
In this embodiment, it should be noted that the symbols that can be used for UCI transmission include: the symbols of non-bearer DMRS, or from waveforms: the DMRS symbols of the resource element RE (Resource Element) that are used for carrying the TB are non-carrier DMRS when the OFDM waveform is used (i.e., DMRS on this DMRS symbol are mapped to part of REs at intervals, the remaining REs can be used for TB transmission, and the remaining REs are considered to be able to transmit UCI) and the non-carrier DMRS symbols are used when the DFT-s-OFDM waveform is used.
Based on the content of the above embodiment, in this embodiment, the conflict includes:
in the same carrier group, resources overlap in the time domain; alternatively, the symbol intervals between channels in the same carrier group are less than a predetermined threshold.
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 may be performed according to the embodiment of the present application if they do not belong to the same carrier group, or may be performed according to the embodiment of the present application if they do not belong to the same carrier group, and if they are not performed according to the embodiment of the present application, it means that simultaneous transmission of the PUCCH and the PUSCH between different carrier groups is supported. The carrier wave group specifically comprises: for example, when secondary carrier (secondary carrier component, SCC) transmission PUCCHs are configured, the primary and secondary PUCCH groups are one carrier group respectively; also for example in a dual connectivity scenario, when a secondary cell group (secondary cell group, SCG) is configured, the primary cell group (master cell group, MCG) and SCG are each one 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 where the two channels are high frequency and the one low frequency, a certain time interval in the time domain is needed for adjusting the radio frequency device even if they do not overlap in the time domain, so that this process is equivalent to time domain overlapping.
Based on the foregoing embodiments, in this embodiment, the PUSCH carrying the multi-slot TB is:
and one TB codes based on the total symbol number corresponding to the PUSCH in a plurality of time slots, and the obtained coding information is scattered in the time slots and transmitted through the corresponding PUSCH.

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 conflict exists between a physical uplink shared channel PUSCH carrying a multi-slot transmission block TB and a physical uplink control channel PUCCH in the time domain, uplink control information UCI is received in a target PUSCH; the target PUSCH is a PUSCH having a collision with the PUCCH or is all PUSCHs corresponding to the same TB in a slot where the PUSCH having a collision with the PUCCH is located.
In this step, it should be noted that, for the physical uplink shared channel PUSCH carrying the multi-slot transport block TB, when there is a collision with the physical uplink control channel PUCCH in the time domain, uplink control information UCI is received in the target PUSCH, where the target PUSCH is the PUSCH having a collision with the PUCCH or is all PUSCHs corresponding to the same TB in the slot in which the PUSCH having a collision with the PUCCH is located. For example, if a PUSCH carrying a multi-slot TB is referred to as one PUSCH in a plurality of slots, meaning that a part of symbols of the PUSCH in a certain slot collide with the PUCCH, UCI may be transferred to be transmitted on the one PUSCH transmitted in a plurality of slots; if the PUSCH carrying a multi-slot TB is referred to as an independent PUSCH in each slot, the PUSCH where there is a collision is a certain independent PUSCH and no other PUSCHs are involved.
According to the information transmission method provided by the embodiment of the invention, when the physical uplink shared channel PUSCH carrying the multi-time slot transmission block TB and the physical uplink control channel PUCCH collide in the time domain, the uplink control information UCI on the PUCCH is transferred to the target PUSCH to be sent, so that UCI is normally transmitted on the PUSCH carrying the multi-time slot TB, UCI discarding is avoided, and the transmission performance of the system is improved.

Based on 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 conflict between the PUSCH carrying the multi-slot transport block TB and the PUCCH in the time domain, UCI of the PUCCH is mapped onto the target PUSCH according to a predetermined mapping rule. The predetermined mapping rule includes: mapping rule 1: taking a symbol contained in the PUSCH which has conflict with the PUCCH as a symbol set, and mapping in the symbol set; mapping rule 2: taking each PUSCH which has conflict with the PUCCH as an independent individual, taking a symbol contained in each PUSCH as a symbol set, and mapping in each symbol set; mapping rule 3: and dividing symbols corresponding to the PUSCH which has conflict with the PUCCH into a plurality of groups, taking the symbols corresponding to the PUSCH transmitted in the same time slot as a group, forming a symbol set, and mapping in each symbol set.
Based on the content of the above embodiment, in this embodiment, the predetermined mapping rule includes at least one of the following:
mapping rule 1: taking a symbol contained in the PUSCH which has conflict with the PUCCH as a symbol set, and mapping in the symbol set;
mapping rule 2: taking each PUSCH which has conflict with the PUCCH as an independent individual, taking a symbol contained in each PUSCH as a symbol set, and mapping in each symbol set;
mapping rule 3: and dividing symbols corresponding to the PUSCH which has conflict with the PUCCH into a plurality of groups, taking the symbols corresponding to the PUSCH transmitted in the same time slot as a group, forming a symbol set, 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 the symbols contained in the PUSCH having a conflict with the PUCCH are used as a symbol set, and mapping is performed in the symbol set; the second mapping rule is a PUSCH-based dispersion mapping, wherein each PUSCH having a collision with the PUCCH is used as an independent entity, the symbols contained in each PUSCH are used as a symbol set, and mapping is performed in each symbol set; the third mapping rule is a dispersion mapping based on time slots, dividing symbols corresponding to PUSCH having collision with PUCCH into a plurality of groups, forming one symbol set by using symbols corresponding to PUSCH transmitted in the same time slot (time slot divided by SCS of PUSCH) as a group, and mapping each symbol set.
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 conforming set, at least one of the following mapping modes is included:
mapping mode 1: mapping from a first symbol available for transmitting UCI, mapping the UCI onto consecutive symbols;
mapping method 2: mapping from a first symbol available for transmitting UCI after a first demodulation reference signal DMRS, mapping the UCI onto consecutive symbols;
mapping method 3: mapping from a predefined symbol, mapping the UCI onto consecutive symbols;
mapping method 4: and mapping around each DMRS symbol, and determining one of the front and rear DMRS in the symbol set or symbols adjacent to the DMRS, which can be used for UCI transmission, as a mapping symbol of UCI.
In this embodiment, it should be noted that, for three mapping rules of UCI on a target PUSCH, four mapping methods are included when mapping is performed in a symbol set, where the mapping methods are respectively as follows:
mapping mode 1: mapping is started from the first symbol available for transmitting UCI, and UCI is mapped onto consecutive symbols (how many resources are occupied by the UCI is pre-calculated, and all resources occupied by the UCI are mapped, and the explanation is omitted. It should be noted that this method is preferably applied to the channel state information CSI, but may also be applied to the AN, and is not particularly limited herein.
Mapping method 2: the UCI is mapped onto consecutive symbols starting from the first symbol available for transmission of UCI after the first demodulation reference signal DMRS. 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 a presumed DMRS position, where the presumed DMRS position may be the first symbol, or the same relative position as the DMRS in a previous PUSCH containing the DMRS or a subsequent PUSCH containing the DMRS (e.g., the DMRS position in the previous PUSCH is the 3 rd symbol among the symbols contained in the PUSCH, the presumed DMRS in the PUSCH is the 3 rd symbol among the symbols contained in the PUSCH). Note that this method is preferably applied to AN, but may also be applied to CSI, and is not particularly limited here.
Mapping method 3: the UCI is mapped to consecutive symbols starting from a predefined one symbol.

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 UCI around each group of DMRS differs by no more than 1 symbol, and when the number of the mapping symbols of UCI around different groups of DMRS is different, more mapping symbols of UCI exist around the previous DMRS group; or the mapping symbols of these UCI are preferentially distributed over the symbols available for UCI transmission around the preceding DMRS group.

In this embodiment, it should be noted that, with mapping mode 2, if there is no DMRS in a certain PUSCH (because of an unavailable symbol, a PUSCH that is obtained by dividing a slot boundary, etc.), mapping is performed based on a assumed DMRS position, where the assumed DMRS position may be the first symbol, or the same relative position as the DMRS in the previous PUSCH containing the DMRS or the subsequent PUSCH containing the DMRS (for example, the DMRS position in the previous PUSCH is the 3 rd symbol in the symbols contained in the PUSCH, the assumed DMRS in the PUSCH is the 3 rd symbol in the symbols contained in the PUSCH). Note that this method is preferably applied to AN, but may also be applied to CSI, and is not particularly limited here.

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