It should be understood that the transmission processing method of the present application may be applied to uplink transmission and may also be applied to downlink transmission, and for convenience of understanding, some contents related to the embodiments of the present application will be described below with respect to the case of PUSCH:

first, the symbol start position and length of the time domain resource allocation.

For the repeat type A (repetition type A) transmission, the corresponding mapping type (mapping type) can be mapping type A and mapping type B;

if the mapping type A is adopted, S is 0, L is 4-14, and S + L is 4-14; wherein, S represents the index value of the initial symbol, and L represents the allocation length;

if the mapping type B is used, S is 0-13, L is 1-14, and S + L is 1-14.

For retransmission type B transmission, the corresponding mapping type can only be mapping type B, S is 0-13, L is 1-14, and S + L is 1-27.

And secondly, configuring time frequency resources.

In the time domain resource configuration, the following parts are included:

(1) slot offset (slot offset) K2;

(2) start and Length Indicator Value (SLIV), or Start symbol (Start symbol) index S and allocation length (allocation length) L; wherein, the indication mode of SLIV is used for repetition type A, and the indication modes of S and L are used for repetition type B;

And thirdly, for the retransmission type A transmission, determining S and L based on the SLIV value obtained according to the first calculation mode. Wherein the first calculation mode is represented as:

if (L-1) is less than or equal to 7, SLIV is 14 (L-1) + S;

If there is an overlap in time of resources of PUCCH and/or PUSCH for transmitting different UCI. The UE needs to multiplex UCI transmitted on multiple channels on the same PUCCH or PUSCH resource.

If there is overlap in the time domain between the PUCCH for UCI transmission and the PUSCH for UE transmission data, the UE multiplexes UCI for transmission on the PUSCH, which may be a scheduled PUSCH or a configured grant (configured grant) PUSCH.

Optionally, if UCI on one PUCCH is multiplexed onto another PUCCH resource, information bits transmitted on two PUCCHs are concatenated and then coded and transmitted together.

And if the UCI on the PUCCH is multiplexed on the PUSCH for transmission, the data parts of the UCI and the PUSCH transmission are separately coded and mapped for transmission. When the UCI is multiplexed on the PUSCH and transmitted, the network device configures a beta-offset (beta-offset) value for the PUSCH to determine the number of modulation symbols occupied by the UCI in the PUCCH, and the larger the beta-offset value is, the more resources occupied by the UCI on the multiplexed PUSCH are. But the modulation symbol number occupied by the UCI cannot exceed a certain threshold, the threshold is obtained by scaling the number of all available Resource Elements (REs) after the overhead of the PUSCH Resource is removed by a certain proportion, the scaling factor is alpha, and the scaling factor is configured by a high-level parameter.

The receiving end can receive corresponding signals based on the target time frequency resource and then demodulate to obtain the data transmitted by the transmitting end.

The occupation of N time slots in the time domain of the target time-frequency resource can be understood as follows: the time domain resource allocation indication is used for scheduling one-time uplink transmission or downlink transmission and occupies at least two time slots. That is, the target time-frequency resource is used to schedule target transmission for transmission in multiple time slots or transmission across time slots, and the target transmission may be uplink transmission or downlink transmission.

Optionally, the time domain resource allocation indicates an index value S for indicating a starting symbol of the target time frequency resource and an allocation length L of the target time frequency resource.

In the embodiment of the present application, the determining manners of S and L may include multiple manners, and the following detailed description is made through different determining manners.

For example, in some embodiments, the S and L are indicated by a first start and length indication SLIV₁Determining; wherein, SLIV₁＝SLIV₂M is an integer greater than or equal to 105, and 14N 1L 14N S, the second starting and length indicating SLIV₂At least one of the following is satisfied:

SLIV in the case of (L-1) ≦ 14 × (N-1) +7₂＝14*[L-1-14*(N-1)]+S；

SLIV in the case of (L-1) > 14 x (N-1) +7₂＝14*[14*N-(L-1)]+(14-1-S)。

Optionally, the value of M may be 105 or 128. Finally, each SLIV₁The values correspond to uniquely determined S and L. It should be understood that the above-described SLIV₁The calculation of (c) can also be applied in the case where N is 1.

The SLIV₂It is understood that the starting and length indications may be based on the range of values of L and SLIV₂By using SLIV₂＝14*[L-1-14*(N-1)]+ S and SLIV₂＝14*[14*N-(L-1)]+ (14-1-S) calculation of SLIV₂Based on SLIV₁＝SLIV₂Calculating to obtain SLIV₁. Optionally, in this embodiment of the present application, the time domain resource allocation indication may include a SLIV₁Values, which may also include SLIV₁The values of S and L correspond to each other.

In some embodiments, the time domain resource allocation indication comprises first indication information indicating the N and second indication information indicating S and a first allocation length L1, the L satisfying: L-L1 +14 (N-1).

In the embodiment of the present application, the use of

The slot number indicating the time domain resource occupation, at this time, the second indication information may be understood as an existing time domain resource allocation indication, and may specifically indicate the first allocation lengths L1 and S,for example, the second indication information may include values of L1 and S determined according to the SLIV calculation method according to the existing protocol, or may include an SLIV value determined according to the above-described SLIV calculation method according to the existing protocol. For example, the SLIV is calculated as follows:

if (L1-1) is less than or equal to 7, SLIV is 14 (L1-1) + S;

otherwise, SLIV ═ 14-L1+1) + (14-1-S);

wherein L1 is more than 0 and less than or equal to 14-S.

In some embodiments, the S and L are indicated by a third start and length indication SLIV₃Determining; wherein, SLIV₃＝14*(L-1)+S。

In the embodiment of the present application, wherein, each SLIV₃Corresponding to uniquely determined S and L. Optionally, the time domain resource allocation indication may include a SLIV₃Values, which may also include SLIV₃The values of S and L corresponding to the values are not further limited herein.

It should be understood that in the embodiment of the present application, when N is equal to 1, it may also be based on SLIV₃A time domain resource allocation indication is determined.

In some embodiments, the time domain resource allocation indication includes third indication information and fourth indication information, where the third indication information is used to determine a value relationship between S and L; the fourth indication information is used for indicating a fourth start and length indication SLIV₄，SLIV₄For determining the S and L.

In the embodiment of the present application, the value relationship between S and L may be specifically expressed as the following two relationships:

(14*(N-1)-S)＜L≤14*(N-1)；

14*(N-1)＜L≤14*N-S。

for different value relationships, SLIV₄Is different, optionally, the SLIV₄At least one of the following is satisfied:

in the case of (14X (N-1) -S) < L.ltoreq.14X (N-1), and (S + 1). ltoreq.14X (N-2) +7, SLIV₄＝14*(S+1)+L-1-14*(N-2)；

L is less than or equal to 14 (N-1) and (S +1) > 14 (N-2) +7 in case of SLIV₄＝14*(14-S-1)+(14*(N-1)-L)；

SLIV in the case of 14 × N-1 < L ≦ 14 × N-S, and (L-1) ≦ 14 × N-1) +7₄＝14*(L-1-14*(N-1))+S；

SLIV in the case of 14 × N-1 < L ≦ 14 × N-S, and (L-1) > 14 × N-1) +7₄＝14*(14*N-L+1)+(14-1-S)。

Further, in a case that N is greater than 1, the third indication information includes indication information of at least one bit, and a most significant bit or a least significant bit of the at least one bit is used for indicating a value relationship between S and L; the value relationship between S and L at least comprises one of the following items:

(14*(N-1)-S)＜L≤14*(N-1)；

14*(N-1)＜L≤14*N-S。

in this embodiment of the application, the third indication information may also be used to determine the value of N. Namely, the value of N can be determined firstly, and a first bit is determined; and determining a second bit according to the determined value relationship between the S and the L, and then cascading the first bit and the second bit to obtain third indication information. The first bit may be located before the second bit or after the second bit. And are not further limited herein.

Alternatively, the second bit may represent (14 × N-1) -S < L ≦ 14 × N-1 using the first value and 14 × N-1 < L ≦ 14 × N-S using the second value. Wherein the first value may be one of 0 and 1 and the second value may be the other.

In an embodiment, in case that the length L of the target time-frequency resource is greater than 14, the size a of the transport block satisfies:

b denotes an intermediate transport block size calculated by occupying 14 symbols in the time domain, and β ═ L/14.

In the embodiment of the present application, when L is less than or equal to 14, the size of the transport block may be calculated according to a conventional Transport Block Size (TBS) calculation method. The conventional TBS calculation method may be understood as the size of a transmission block calculated according to an OFDM symbol actually occupied by a time domain. That is, the size of the intermediate transport block is calculated by occupying a maximum of 14 OFDM symbols according to a conventional TBS calculation method, and then the calculated B is scaled according to the size of β to obtain the size of the final transport block.

Optionally, in an embodiment, the step of mapping the transport block to the target time-frequency resource includes:

dividing the transmission block into N sub-transmission blocks according to the first symbol number distributed in each time slot;

preprocessing each sub-transmission block to obtain modulation symbols corresponding to N sub-transmission blocks;

mapping modulation symbols corresponding to the N sub-transmission blocks to the target time frequency resource;

wherein the first symbol number does not include the number of OFDM symbols occupied by a Demodulation Reference Signal (DMRS).

In the embodiment of the present application, a modulation symbol corresponding to a sub-transport block is to be understood as a modulation symbol of the sub-transport block before mapping, that is, a modulation symbol obtained after layer mapping and precoding. For example, the sub-transport block in each time slot may be used as a unit for preprocessing, so as to obtain a modulation symbol before mapping corresponding to each sub-transport, and finally, the modulation symbol is mapped to the time-frequency resource of each time slot corresponding to the target time-frequency resource for transmission.

Optionally, the size of each sub-transport block may be set according to actual needs, for example, in an embodiment, the sizes of the N sub-transport blocks are the same.

In another embodiment, the size of each of the sub-transport blocks is proportional to the number of the first symbols allocated in the time slot in which the sub-transport block is located.

That is to say, in the embodiment of the present application, the larger the number of the first symbols allocated in a time slot is, the larger the size of the corresponding sub-transport block is, so that it can be ensured that the code rates transmitted in each time slot are kept consistent, and the reliability of transmission is ensured.

Optionally, in another embodiment, the step of mapping the transport block to the target time-frequency resource includes:

preprocessing the transmission block to obtain a modulation symbol corresponding to the transmission block;

and mapping the modulation symbols corresponding to the transmission blocks to the target time frequency resources in sequence.

In the embodiment of the application, the transmission block can be regarded as a whole and is not split. And finally, mapping the modulation symbols before mapping to the time frequency resources of each time slot in the target time frequency resources in sequence for transmission.

It should be understood that the preprocessing may include Cyclic Redundancy Check (CRC), channel coding, rate matching, scrambling, modulation, layer mapping, and precoding, obtaining the modulation symbols before mapping, and then performing resource mapping.

Optionally, after the step of determining the scheduled target time-frequency resource according to the time-domain resource allocation indication, the method further includes:

mapping a first DMRS to the target time-frequency resource;

wherein the determination of the time-domain location of the first DMRS comprises any one of:

determining the time domain position of the DMRS corresponding to each time slot according to the number of the OFDM symbols allocated to each time slot;

and determining the time domain position of the first DMRS according to the OFDM symbol number of the target time frequency resource.

The OFDM symbol number of the target time-frequency resource may be understood as a total scheduled OFDM symbol number or a total symbol number allocated to the target time-frequency resource in the N time slots. The first DMRS may be understood as that the DMRS that needs to be transmitted on the target time-frequency resource is scheduled and transmitted in this time.

In this embodiment of the present application, the determination manner for the time domain position of the first DMRS may include the following two manners.

In the method 1, the time domain position of the DMRS corresponding to each slot may be determined in units of slots. That is, the mapping of the DMRS may be performed in units of slots.

In mode 2, when the total number of allocated OFDM symbols is greater than 14, the time domain position of the DMRS may be determined according to the total number of allocated OFDM symbols.

For the first mode, it is assumed that the total number of allocated OFDM symbols is 17, the 17 OFDM symbols occupy two slots, the first slot occupies 10 OFDM symbols, and the second slot occupies 7 OFDM symbols. At this time, the first time slot determines the time domain position of the DMRS symbol in the time slot according to 10 OFDM symbols; and the second time slot determines the time domain position of the DMRS symbol in the time slot according to 7 OFDM symbols.

For the above mode 2, the determining the position of each group of DMRS symbols may be performed according to every 14 symbols as a group, in other words, in the case that the number of OFDM symbols of the target time-frequency resource is greater than 14, the determining the time-domain position of the first DMRS according to the number of OFDM symbols of the target time-frequency resource includes:

dividing the OFDM symbol number of the target time frequency resource into at least two symbol groups according to each continuous 14 symbols as one group;

and determining the time domain position of the DMRS corresponding to the symbol group according to the number of OFDM symbols in each symbol group.

Assuming that the total number of allocated OFDM symbols is 17, grouping may result in two OFDM symbol groups, i.e. the first 14 OFDM symbols are the first group of OFDM symbols, and the last 3 OFDM symbols are the second group of OFDM symbols. At this time, the first group of OFDM symbols determines the time domain position of the DMRS mapped on the 14 OFDM symbols by the number of 14 OFDM symbols. The first group of OFDM symbols determines the time domain position of the DMRS mapped on the 3 OFDM symbols by the number of 3 OFDM symbols.

Optionally, the mapping manner of the DMRS satisfies any one of the following:

mapping type B is used by default;

the priority of mapping type a is greater than the priority of mapping type B.

In this embodiment, as for the above-described mode 1, the mapping scheme for the DMRS may be understood as a mapping scheme for the DMRS in each slot, and as for the above-described mode 2, the mapping scheme for the DMRS may be understood as a mapping scheme for the DMRS in each OFDM symbol packet.

The priority of the mapping type a is greater than that of the mapping type B, which may be understood as that, when the condition corresponding to the mapping type a is satisfied, DMRS mapping is performed according to the mapping type a, otherwise, DMRS mapping is performed according to the mapping type B. For example, with respect to the mode 1, for PUSCH transmission, when the number of OFDM symbols allocated in a certain time slot is greater than or equal to 4 and the starting symbol index is 0, that is, S is 0, DMRS mapping is performed according to the mapping type a, otherwise DMRS mapping is performed according to the mapping type B; for the mode 2, for PUSCH transmission, when the number of OFDM symbols of a certain OFDM packet is greater than or equal to 4 and the starting symbol index is 0, that is, S is 0, DMRS mapping is performed according to the mapping type a, otherwise DMRS mapping is performed according to the mapping type B.

Further, in a case that the time domain position of the DMRS corresponding to each of the slots is determined according to the number of OFDM symbols allocated to each of the slots, the DMRS corresponding to each of the slots further satisfies: under the condition that the number of OFDM symbols allocated to a first time slot is 1 and the first time slot and a second time slot meet a preset condition, mapping no DMRS or only mapping the DMRS corresponding to the first time slot in the first time slot;

not mapping the DMRS in the first time slot may be understood as mapping only data in the first time slot, which does not support frequency hopping.

It should be understood that in the embodiment of the present application, the DMRS symbols transmitted in the second slot may be reduced.

Optionally, in an embodiment, the preset condition includes at least one of the following:

the first time slot and the second time slot use the same antenna port;

the power deviation between the antenna ports used by the first time slot and the second time slot is smaller than or equal to a first preset value;

the phases between the antenna ports used by the first time slot and the second time slot are continuous;

the first time slot and the second time slot use the same precoding parameter;

the first time slot and the second time slot use the same spatial filtering parameters.

It should be noted that the target time-frequency resource may be used for uplink transmission or downlink transmission, and in the following embodiment, the case of resource collision is described by taking uplink transmission as an example. For example, the step of mapping the transport block to the target time-frequency resource, where the transport block is carried on a first physical uplink shared channel PUSCH, and when the first PUSCH overlaps with a physical uplink control channel PUCCH in time domain (overlapping), includes:

determining the transmission modes of the first PUSCH and the PUCCH according to target information;

wherein the target information comprises at least one of:

multiplexing, by a PUCCH, a number P of modulation symbols transmittable on a first PUSCH;

the number of OFDM symbols distributed by PUSCH in each time slot in N time slots;

and the number of available modulation symbols for PUSCH transmission in each time slot in the N time slots.

The P is determined by a second symbol number when the first PUSCH and PUCCH are multiplexed, and the second symbol number is the following minimum OFDM symbol number:

the OFDM symbol number is preset, or the maximum OFDM symbol number when the configurable PUSCH is multiplexed with the PUCCH in a time slot;

the number of OFDM symbols actually allocated to the first PUSCH.

Optionally, the transmission mode includes at least one of:

under the condition that P is larger than the number of modulation symbols available for PUSCH transmission in a third time slot, not sending a PUSCH in the third time slot;

multiplexing the PUCCH with a PUSCH of a fourth slot if the fourth slot exists in the N slots;

transmitting at least one of the PUCCH and the first PUSCH without a fourth slot of the N slots;

the third slot is a slot where the first PUSCH and the PUCCH overlap, and the fourth slot is a slot where the number of modulation symbols available for PUSCH transmission is greater than P.

In the embodiment of the present application, instead of transmitting the PUSCH in the third slot, it may be understood that the PUSCH in the third slot is not transmitted only in the third slot, that is, the PUSCH in the third slot of the puncture (punch) is scheduled to be transmitted, for example, in slot 1 and slot 2, and if the PUSCH transmitted in slot 1 overlaps with the PUCCH, only the PUSCH in slot 2 is transmitted. It can also be understood that the first PUSCH is transmitted starting one slot after the third slot.
