Description

Feedback method and device of confirmation information and receiving method and device of confirmation information

Technical Field

The present invention relates to the field of communications, and in particular, to a method and an apparatus for feeding back acknowledgment information, and a method and an apparatus for receiving acknowledgment information.

Background

In the related art, a New generation mobile communication system NR (New Radio) under study is one of the work focus of the current 3 GPP.

In the NR system that can be determined at present, there are 3 typical traffic types in the future. Common services include: enhanced Mobile bandwidth eMBB (enhanced Mobile BroadBand), ultra-high Reliable Ultra-Low Latency Communications URLLC (Ultra-Reliable and Low Latency Communications), and massive Internet of things mMTC (massive Machine Type Communications). These services have different requirements with respect to delay, coverage and reliability. For example, for the eMBB, high peak transmission rate is mainly emphasized, the requirement on delay is not high (low delay is not required), and the reliability is required. For URLLC, low latency, high reliability transmission is emphasized, which is very demanding on latency. For mtc, a large number of medium terminals are emphasized, the connection density is high and more transmission coverage is required, and there is little requirement for latency.

In addition, in NR, a new codec is discussed and is likely to be introduced. In this way, the receiving end device is allowed to decode according to the received OFDM symbol of the OFDM technology, that is, one OFDM symbol is decoded when one OFDM symbol is received, which is a "pipelined" decoding method, and this method is mainly used to accelerate the receiving end device to quickly feed back the acknowledgement information to the transmitting end device after the receiving end device has received the last OFDM symbol data of this transmission, and obviously, this "pipelined" decoding can achieve the purpose of quickly feeding back the acknowledgement information.

However, for the above decoding method, some better acknowledgement information feedback should be studied, so that the receiving end device feeds back which part of data has an error as accurately as possible, instead of feeding back an acknowledgement information for a transport block at present, and if an error occurs, it is not clear that a specific part of data has an error. The sender device can thus send the entire Transport Block (TB) only once again. In the related art, the above problem may be solved in a manner based on code block group feedback, that is, one transport block is fed back acknowledgement information according to a plurality of code block groups, respectively. However, it also brings new problems, such as that the overhead of the CBG feedback-based acknowledgement information is large, and in most cases each CBG is decoded correctly, so that only in few cases the CBG feedback retransmission is actually utilized. This also means that in most cases, the determination information fed back based on the Code Blocks Group (CBG for short) does not serve to improve retransmission efficiency, and brings a large overhead. For example, if 8 CBGs are configured to feed back the acknowledgement information, at least 8 bits of acknowledgement information need to be sent each time.

In the related art, transmission is performed once, and if the receiving end equipment decodes correctly, 1-bit ACK/NACK information is fed back. Forming ACK/NACK information based on block groups of Codes (CBGs), one for each CBG, is currently under discussion in NR systems. For the CBG with decoding error, the sending end device can be retransmitted with the CBG with decoding error, so that all data at this time does not need to be retransmitted, and the retransmission efficiency is improved. However, bit overhead of the corresponding ACK/NACK information increases.

Generally, for a system, the probability that one transmission is correctly decoded by the receiving end device is about 90%, that is, the probability that each CBG feeds back ACK information is 90% by using CBG-based ACK/NACK feedback. Thus, in practice, for one transmission, the probability of not requiring retransmission, i.e. 90%. But based on the CBG feedback mechanism the corresponding ACK/NACK overhead per transmission would be made relatively large.

How to utilize the CBG feedback mechanism to improve the retransmission efficiency and reduce the necessary signaling overhead at the same time is yet to be researched.

For the problem of how to perform more accurate and efficient feedback of the confirmation information in the related art, no effective solution exists at present.

The following detailed description is given with reference to preferred embodiments of the present invention.

It is first explained that resource 1 in the preferred embodiment of the present invention may be the first resource in the above-mentioned embodiment, resource 2 may be the second resource, format 1 may be the first format, and format 2 may be the second format.

The method comprises the following steps: corresponding to the following specific example 1

For a receiving end device, configuring a Transport Block (TB) based resource 1 for the receiving end device, and sending ACK/NACK information; allocating resources 2 for forming and sending ACK/NACK information based on Code Blocks Group (CBG for short) for the configuration; for one transmission, after the receiving end device correctly decodes all received CBGs or correctly decodes the received transport blocks TBs, the receiving end device forms corresponding ACK/NACK information based on the TBs (each TB forms one 1-bit ACK/NACK information) and transmits it in resource 1 using format 1. Otherwise, the receiving end device forms corresponding ACK/NACK information based on the CBGs (each CBG forms a 1-bit ACK/NACK information) and transmits it in resource 2 using format 2. Fig. 3 is a flow chart of a method 1 according to a preferred embodiment of the invention.

Format 1 is used for 1-2 bit Uplink Control Information (UCI) Information transmission, and generally, it employs higher reliability. Format 2 is for UCI information transmission greater than 2 bits. The uplink control information includes ACK/NACK information and other uplink feedback information (the other uplink feedback information may refer to the definition in the NR system).

For one UE1, there is a greater probability of using resource 1, so UE1 uses resource 2 with a lesser probability, so more user terminals UE (e.g. UE2, UE3, UE 4) will be configured to share the same resource 2 with UE 1. I.e. multiple UEs share the use of resource 2. For example, the UEs sharing the resource 2 may be UEs farther away from the base station and UEs closer to the base station, respectively.

I.e., the corresponding ACK/NACK formed is transmitted in resource 1 and resource 2 using format 1 and format 2, respectively. Then more UEs are sharing resource 2.

Embodiment 1 in this case would become embodiment 3 if resource 1 is located in resource 2, or resource 1 is part of resource 2.

Note that resource 1 is a resource for transmitting one format 1; resource 2 is a resource that transmits one format 2. Typically, resource 2 is greater than or equal to resource 1. Because more bits are transmitted in resource 2, which is greater than 2 bits.

The transmitting end device (e.g., base station) first receives ACK (since here most is ACK information and few cases are NAKC information) information formed based on TBs in resource 1 in accordance with format 1, and if the ACK information is detected, the UE is considered to be ACK/NACK formed based on TBs and the UE is considered to correctly decode transmitted data. If the ACK information is not detected in the resource 1, the base station receives the ACK/NACK information formed based on the CBG in the resource 2 according to the format 2, and if the ACK/NACK is detected, the base station retransmits the CBG with decoding errors of the UE.

The method 2 comprises the following steps: corresponding to the following specific example 2

For one transmission, after the receiving end device correctly decodes all received CBGs or the receiving end device correctly decodes the received transport blocks TBs, the receiving end device forms corresponding ACK/NACK information based on the TBs (each TB forms one 1-bit ACK/NACK information) and transmits it through the PUSCH of the receiving end device itself by puncturing or rate matching. Otherwise, the receiving end device forms corresponding ACK/NACK information based on the CBGs (each CBG forms a 1-bit ACK/NACK information) and transmits it in resource 2 using format 2. Resource 2 is configured for the UE by the base station.

Wherein, the format 2 is used for transmitting UCI information larger than 2 bits. The uplink control information (abbreviated UCI) includes ACK/NACK information and other uplink feedback information (the other uplink feedback information can refer to the definition in the NR system).

For one UE1, there is a greater probability that ACK/NACK formed based on TBs is transmitted through puncturing or rate matching the receiving end device's own PUSCH, so UE1 uses resource 2 with a smaller probability, and thus, more UEs (e.g., UE2, UE3, UE 4) will be configured to share the same resource 2 with UE 1. I.e. multiple UEs share the use of resource 2. For example, the UEs sharing the resource 2 can be UEs farther away from the base station and UEs closer to the base station, respectively.

The transmitting end device (e.g. base station) firstly receives ACK (because ACK information is always present) information formed based on TB in PUSCH of the UE according to the agreed puncturing rule or rate matching pattern, if the ACK information is detected, the UE is considered to be ACK/NACK formed based on TB, and the UE is considered to correctly decode the transmitted data. If the ACK information is not detected, the base station receives ACK/NACK information formed based on the CBG in the resource 2 according to the format 2, and if the ACK/NACK is detected, the base station retransmits the CBG with decoding errors of the UE.

It needs to be supplemented that the base station can know whether the UE has PUSCH transmission, if the base station finds that the UE does not have PUSCH to continue transmission, but still has ACK/NACK to be sent, at this time, if the UE does not have PUSCH simultaneous transmission, the UE sends ACK/NACK information formed according to TB in resource 2; or the base station allocates resource 1 for transmitting the ACK/NAK information formed according to TBs to the UE in time (like resource 1 in opt 1).

The method 3 comprises the following steps: corresponding to the following specific example 4

For one transmission, after the receiving end device correctly decodes all received CBGs or the receiving end device correctly decodes the received transport blocks TBs, the receiving end device forms corresponding ACK/NACK information based on the TBs (each TB forms one 1-bit ACK/NACK information) and transmits it through the PUSCH of the receiving end device itself by puncturing or rate matching. Otherwise, the receiving end device forms corresponding ACK/NACK information (each CBG forms one 1-bit ACK/NACK information) based on the CBGs and processes its own PUSCH to transmit it through another puncturing rule or rate matching.

The transmitting device (e.g., base station) first receives ACK (because ACK information is always present) information formed based on TBs in a promissory puncturing or rate matching pattern in the PUSCH of the UE, and if ACK information is detected, the UE is considered to be ACK/NACK formed based on TBs, and the UE is considered to correctly decode transmitted data. If the ACK information is not detected, the base station receives ACK/NACK information formed based on CBGs in a PUSCH of the UE according to an appointed punching or rate matching pattern, and if the ACK/NACK is detected, the base station retransmits the CBGs with errors decoded by the UE.

Likewise, if the base station finds that the UE has no PUSCH transmission but still has ACK/NACK to be transmitted, the base station can timely allocate resources for transmitting ACK/NACK formed according to TB and resources for forming ACK/NACK according to CBG.

The method 4 comprises the following steps: corresponding to the following specific example 5

If the UE determines that the UE needs to transmit the ACK/NACK information and other UCI information simultaneously in one feedback, the UE forms the ACK/NACKs information according to the CBG and transmits the ACK/NACKs information after jointly coding with other UCI information. Because the transmission time of the ACK/NACK and other UCIs is configured by the base station, the base station always knows whether the other UCIs and the ACK/NACK are transmitted simultaneously. If the base station determines that the UE needs to simultaneously transmit ACK/NACK and other UCI information in one feedback, the base station considers that the ACK/NACK information in the feedback is ACK/NACKs formed according to CBG. Fig. 4 is a flow chart of method 4 according to a preferred embodiment of the invention.

When the UE is configured to operate according to opt1, opt2, opt3, or opt4, if the UE finds that in one feedback, the UE needs to transmit ACK/NACK and other UCI information at the same time, at this time, the UE always forms a plurality of corresponding ACK/NACKs information according to CBG and transmits the ACK/NACKs information and other UCI information at the same time. For example, when the UE finds that it will need to transmit ACK/NACK and other UCI simultaneously, even if the UE correctly decodes all CBGs or TBs, the UE does not form ACK information of 1bit at this time, but forms ACK/NACK according to CBGs (each CBG forms one ACK information). The formed ACK/NACK and other UCIs are transmitted in a corresponding manner according to a plurality of ACK/NACKs specified by opt1, opt2, opt3 or opt 4. Because the transmission time of the ACK/NACK and other UCI is configured by the base station, the base station always knows whether other UCI and ACK/NACK are transmitted simultaneously. Correspondingly, if the base station determines that the UE needs to transmit ACK/NACK and other UCI information simultaneously in one feedback, the base station considers that the ACK/NACK information in the feedback is ACK/NACKs formed according to CBG.

The following are specific implementations of preferred embodiments of the invention:

detailed description of the preferred embodiment 1

For a receiving terminal device, configuring a resource 1 formed based on a transmission block TB and sending acknowledgement information ACK/NACK information; allocating resources 2 for the configuration based on the code block group CBG and sending ACK/NACK information; for one transmission, after the receiving end device correctly decodes all received CBGs or correctly decodes the received transport blocks TBs, the receiving end device forms corresponding ACK/NACK information based on the TBs (each TB forms one 1-bit ACK/NACK information) and transmits it in resource 1 using format 1. Otherwise, the receiving end device forms corresponding ACK/NACK information based on the CBGs (each CBG forms a 1-bit ACK/NACK information) and transmits it in resource 2 using format 2.

Wherein, the format 1 is used for the transmission of 1-2 bit uplink control information UCI information, and generally, the method adopts higher reliability. Format 2 is for UCI information transmission greater than 2 bits. The uplink control information (abbreviated UCI) includes ACK/NACK information and other uplink feedback information (the other uplink feedback information may refer to the definition in the NR system).

For one UE1, there is a greater probability of using resource 1, so UE1 uses resource 2 with a lesser probability, so more UEs (e.g., UE2, UE3, UE 4) will be configured to share the same resource 2 with UE 1. I.e. multiple UEs share the use of resource 2. For example, the UEs sharing the resource 2 may be UEs farther away from the base station and UEs closer to the base station, respectively.

I.e., the corresponding ACK/NACK formed is transmitted in resource 1 and resource 2 using format 1 and format 2, respectively. Then more UEs share resource 2.

If resource 1 is located in resource 2, or resource 1 is part of resource 2, embodiment one in this case would be changed to embodiment three.

Specific example 2

The transmitting end device (e.g. base station) firstly receives ACK (because ACK information is always present) information formed based on TB in PUSCH of the UE according to the agreed puncturing rule or rate matching pattern, if the ACK information is detected, the UE is considered to be ACK/NACK formed based on TB, and the UE is considered to correctly decode the transmitted data. If the ACK information is not detected, the base station receives ACK/NACK information formed based on the CBG in the resource 2 according to the format 2, and if the ACK/NACK information is detected, the base station retransmits the CBG with errors decoded by the UE.

Specific example 3

In this particular embodiment 3, resource 1 is a subset of resource 2, i.e. resource 1 is located in resource 2, or resource 1 is part of resource 2.

Specific example 4

The transmitting device (e.g., base station) first receives ACK (because ACK information is always present) information formed based on TBs in a promissory puncturing or rate matching pattern in the PUSCH of the UE, and if ACK information is detected, the UE is considered to be ACK/NACK formed based on TBs, and the UE is considered to correctly decode transmitted data. If the ACK information is not detected, the base station receives ACK/NACK information formed based on the CBG in a PUSCH of the UE according to an appointed punching or rate matching pattern, and if the ACK/NACK is detected, the base station retransmits the CBG with decoding errors of the UE.

Specific example 5

If the UE determines that the UE needs to transmit the ACK/NACK information and other UCI information simultaneously in one feedback, the UE forms the ACK/NACKs information according to the CBG and transmits the ACK/NACKs information after jointly encoding with other UCI information. Because the transmission time of the ACK/NACK and other UCIs is configured by the base station, the base station always knows whether the other UCIs and the ACK/NACK are transmitted simultaneously. If the base station determines that the UE needs to simultaneously transmit ACK/NACK and other UCI information in one feedback, the base station considers that the ACK/NACK information in the feedback is ACK/NACKs formed according to CBG.

Specific example 6

For a receiving terminal device, configuring a resource 1 formed based on TB and sending ACK/NACK information; allocating resources 2 for the configuration based on CBG formation and sending ACK/NACK information; for one transmission, for example, one TB is transmitted, when the receiving end device correctly decodes all received CBGs or correctly decodes the received transport blocks TBs, the receiving end device forms corresponding ACK/NACK information based on the TBs (each TB forms one 1-bit ACK information) and transmits it in resource 1 using format 1; or, when the receiving end device does not correctly decode all received CBGs, the receiving end device forms corresponding ACK/NACK information based on TBs (each TB forms a 1-bit NACK information) and transmits it in resource 1 using format 1. Otherwise, the receiving end device forms corresponding ACK/NACK information based on the CBGs (each CBG forms a 1-bit ACK/NACK information) and transmits it in resource 2 using format 2.

Wherein, the format 1 is used for 1-2 bit UCI information transmission, generally, it adopts higher reliability. Format 2 is for UCI information transmission greater than 2 bits. The uplink control information (abbreviated UCI) includes ACK/NACK information and other uplink feedback information (the other uplink feedback information can refer to the definition in the NR system).

For one UE1, there is a greater probability of using resource 1, so UE1 uses resource 2 with a lesser probability, so more UEs (e.g., UE2, UE3, UE 4) will be configured to share the same resource 2 with UE 1. I.e. multiple UEs share the use of resource 2. For example, the UEs sharing the resource 2 can be UEs farther away from the base station and UEs closer to the base station, respectively.

The emphasis is on transmitting the corresponding ACK/NACK formed in resource 1 and resource 2 using format 1 and format 2, respectively. Then more UEs share resource 2.

If resource 1 is located in resource 2, or if resource 1 is part of a resource, opt1 will become opt3.

Description of the drawings: resource 1 is a resource for transmitting one format 1; resource 2 is a resource that transmits one format 2. Typically, resource 2 is greater than or equal to resource 1. Because more bits are transmitted in resource 2, which is greater than 2 bits.

A transmitting end device (e.g., a base station) first receives ACK or NACK information formed based on TBs in resource 1 according to format 1, considers that the UE is ACK/NACK formed based on the TBs and that the UE correctly decodes transmitted data if the ACK information is detected, and considers that the UE is ACK/NACK formed based on the TBs and that the UE does not correctly decode each CBG corresponding to the transmitted data if the NACK information is detected. If the base station does not detect the ACK/NACK sent by the UE according to the format 1 in the resource 1, the base station receives the ACK/NACK information formed based on the CBG according to the format 2 in the resource 2, and if the ACK/NACK is detected, the base station retransmits the CBG with the decoding error of the UE.

Specific example 7

The present embodiment provides a method for dividing code blocks CB into code block groups CBG. One transport block TB may include a plurality of code blocks CB, which are formed in units of code block groups CBG when forming acknowledgement information (ACK/NACK).

When a plurality of CBGs are divided into a plurality of CBGs, the CBG placement positions containing a relatively large number of CBs are corresponding to the OFDM symbol positions where adjacent DMRS are located, relative to the CBG containing a relatively small number of CBs.

Alternatively, all CBGs with a large number of CBs are placed before CBGs with a small number of CBs (for example, when the CBG number is smaller, the CBGs are considered to be placed relatively earlier in the scheduling cell, in time order), because the DMRS is in front of the data in the scheduling cell.

Or, the OFDM symbol corresponding to the CB containing the CBG with the larger number of CBs is not later than the OFDM symbol corresponding to the CB containing the CBG with the smaller number of CBs.

In feeding back the acknowledgement information based on CBGs (i.e., the acknowledgement information is formed in units of CBGs, one acknowledgement information per CBG), the first CB (e.g., the CB with the smallest number) is divided in the first CBG (the CBG with the smallest number) among the CB-to-CBG divisions. The OFDM symbol used by the first CB includes the first OFDM symbol of the OFDM symbols occupied by the transport block TB in which it is located.

The first CBG (the CBG with the smallest number) at least includes one CB, and when the CBG includes one CB, the CB is the first CB in the current transmission. The current transmission may be (the first CB) in one TB of the initial transmission, or may be (the first CB) in CBs of the retransmitted CBGs.

In one transmission, if num is contained _CB CBs (numbered from 0) and required to be divided into num _CBG The number of CBG groups is the kth (numbered from 0) CBG (marked as CBG) _k ) The number of CB included satisfies the following equation 1 or equation 2. Wherein, once transmission includes: one TB transmission, one data retransmitted according to CBG, one retransmitted data, one punctured data in one TB transmission, or one remaining data after being punctured in one TB transmission.

The equation 1 is:

R＝num _CB modnum _CBG ；

CBG _k comprises CB as follows:

wherein the content of the first and second substances,

or

Or

If the value of n-1 or m-1 is less than 0 in the calculation of the corresponding k value, the CBG corresponding to the k value _k No CB is included.

The equation 2 is:

R＝num _CB modnum _CBG ；

CBG _k comprises CB as follows:

wherein, the first and the second end of the pipe are connected with each other,

or

Or

If some CBG is present _k When no CB is contained in the CBG, these CBGs are _k The corresponding acknowledgement information is reserved to padding and needs to be sent. Or these CBGs _k The corresponding acknowledgement information is not transmitted (the number of bits actually transmitted will be reduced).

For one data transmission, each CBG _k The number of the first CB included in (a) is the number of the corresponding CB when i is 0 in equation 1 or equation 2.

When the number of CBGs is less than the number of CBGs in one transmission, the last CB does not belong to the last CBG; or when the number of CBGs is greater than the number of CBGs, the last CB belongs to the last CBG.

Specific example 8

The embodiment provides a scheme for acquiring PUCCHs with different symbol number lengths, and provides symbols corresponding to some preferred PUCCHs, DMRS patterns and frequency hopping modes.

It should be noted that the drawings of embodiment 8 are collectively listed in the latter half of embodiment 8.

In the long PUCCH format configuration mode based on predefined puncturing, the predefined mode refers to symbol positions of DMRS in a slot with a predefined length of 14 symbols, and the rest of the symbol positions are UCI, and symbols in the slot are defined as 0 th, 1 th, 2 th, … and 13 th symbols from left to right. As shown in fig. 9 and 10. The long PUCCH is (14-N) symbols-blanked out of predetermined 14 symbols according to a required length N (number of symbols), and finally, the long PUCCH having the length of N symbols is obtained. For example, the long PUCCH will reserve a certain length in the predefined format while dropping symbols in other positions according to its starting position and duration length. One preferred way to type symbols is: the long PUCCH is always terminated at the end of the scheduling unit (excluding the short PUCCH symbol if any) so that the long PUCCH start can be determined according to the number of symbols of the long PUCCH. The symbols preceding the starting symbol can be dropped.

For UCI of at most 2 bits, a slot structure having a length of 14 symbols is predefined. Wherein the predefined DMRS locations may be distributed differently while maintaining a DMRS density of 50%. That is, half of the symbols are DMRS symbols and half are UCI symbols. The DMRS symbols and UCI symbols are distributed at odd symbol positions or even symbol positions, respectively, as shown in fig. 5. As shown in fig. 5.

For UCI larger than 2bit, a slot structure with a length of 14 symbols is predefined. The predefined DMRS positions can also adopt different distribution modes, and 20% -30% of DMRS density is kept. That is, there are 3 to 4 DMRS symbols out of 14 symbols. As shown in fig. 6, in the multiple DMRS distribution schemes, (b), (c), and (d) include 3 DMRS symbols, and (a), (e), (f), (g), and (h) include 4 DMRS symbols.

Fig. 7 to 10 show examples of generating different length PUCCH structures for predefined structure puncturing. As can be seen from fig. 7 to 10, even with a long PUCCH having the same length, different component structures are obtained depending on the puncture position.

Example 1 of specific embodiment 8:

based on the predefined format (e) in fig. 6, frequency hopping patterns of the long PUCCH at different puncture locations are provided when the long PUCCH length is 4,7,11, 14.

The position set of the DMRS in the predefined format (e) is {0,3,7,11}, and when the puncturing starting symbol is the DMRS or the UCI symbol adjacent to the left side of the DMRS, a long PUCCH structure of the preposed DMRS is obtained, so that channel estimation is completed earlier, and the demodulation processing time of the long PUCCH is saved. Thus, the optimal puncture start symbol set for any long PUCCH between 4 and 14 symbol lengths under the predefined format (e) of fig. 2 is {0, 2, 3, 6, 7, 10, 11}.

If a pattern of frequency hopping once in a time slot is considered, the following principle (1) should be followed that the number of symbols contained in two frequency hopping parts is as equal as possible, and if the number of symbols is not equal, the difference value of the number of symbols should be as small as possible; (2) The number ratio of DMRS symbols to UCI symbols in the two frequency hopping parts is consistent or close to the number ratio of DMRS symbols to UCI symbols in the two frequency hopping parts as much as possible; (3) The two hopping parts should follow as much as possible the structure of the DMRS preamble (DMRS located at the first or second symbol position).

The hopping pattern x + y in tables 1 to 3 below indicates that frequency hopping is performed only once in one time slot, and the number of symbols included in the two hopping parts is x and y symbols, respectively. Under the same frequency hopping pattern x + y, the specific frequency hopping pattern structures are different due to different long PUCCH structures (different numbers and position distributions of DMRS and UCI symbols). For example, in fig. 4, two hopping patterns 3+4 or 4+3 exist for long PUCCH hopping of length 7 symbols, but under different puncture start symbols, 3-symbol hopping part and 4-symbol hopping part in 3+4 or 4+3 have the same or different structural configurations. When the puncturing start symbol is 0, the DMRS symbols of the hopping parts of 3 symbols in the 3+4 hopping pattern are located at the first symbol position, and when the puncturing start symbol is 2, the DMRS symbols of the hopping parts of 3 symbols in the 3+4 hopping pattern are located at the second symbol position.

"-" indicates that the long PUCCH format determined by the puncture start symbol and length does not support frequency hopping.

"X" indicates that this puncture start symbol and length combination is not present. Table 1 is a hopping pattern table based on the predefined format (e) of example 1 of specific embodiment 8.

Specific example 9

CBG-based retransmission is discussed in the standard formulation of NR, there is a suggestion in DCI to indicate which CBG is retransmitted or newly transmitted (denoted as CBG retransmission indication signaling). That is, each CBG will have a corresponding indication signaling whether the CBG is a retransmitted CBG or a newly transmitted CBG. One transport block TB contains at least one CB and one CBG contains one or more CBs.

The following provides a data transmission method, which can support simultaneous transmission of a plurality of data blocks, and particularly can effectively improve retransmission efficiency when retransmission based on CBG is involved.

And scheduling and transmitting a plurality of data blocks in one scheduling unit in a time division multiplexing mode through one downlink control information DCI. One data block corresponds to one transport block, or one data block corresponds to part or all of code blocks CB or code block groups CBG of one transport block. For example, fig. 19 is a schematic diagram illustrating that a process number is used when a retransmitted CBG and a new TB are simultaneously transmitted according to embodiment 9 of the present invention, in fig. 19, a transport block #1 is initially transmitted in a scheduling unit n, and the transport block can be divided into 4 CBGs (or the transport block corresponds to 4 CBGs, and the actual transmission is still performed according to CBs, but the future acknowledgement information is fed back by dividing into 4 CBGs). Assuming that the CBG #0 and CBG #2 of TB #1 are not decoded correctly by the receiving end device, then performing retransmission of CBG #0 and CBG #2 of TB #1 in the scheduling unit n + k 1; meanwhile, the newly transmitted TB #2 and the TB #2 in the scheduling unit n + k1 are divided into 2 CBGs (the two CBGs may have the same size as the CBG of TB #1 or different sizes, and the required resources thereof may be adjustable in the frequency domain and/or the time domain, but the relative order of all the CBGs in the scheduling unit, including the CBGs of different TBs, must be kept unchanged), which are respectively the CBG #0 and the CBG #1 in oblique lines, and their sequential positions in the scheduling unit replace the sequential positions of the CBG #1 (snowflake point, opposite hook) and the CBG #3 (snowflake point, opposite hook) of the TB #1 that have been correctly transmitted in the scheduling unit n. Assuming that CBG #0 of TB #1 is still not correctly received and CBG #2 is correctly received in scheduling unit n + k 1; in addition, the CBG #1 of the TB #2 in the scheduling unit n + k1 is not correctly received, and the CBG #0 is correctly received; then, in scheduling unit n + k2, CBG #0 of TB #1 continues to be retransmitted; CBG #1 of TB #2 is retransmitted; TB #3 is a new TB, which is initially transmitted, and includes CBG #0 (reverse-slanted line) and CBG #1 (reverse-slanted line), whose sequential positions replace the sequential positions of CBG #2 (snowflake, opposite-slanted line) of TB #1 and CBG #0 (forward-slanted line, opposite-slanted line) of TB #2 that have been correctly transmitted in the scheduling unit n + k1.

One DCI is transmitted in the PDCCH of the scheduling unit, including one progress number, and the progress number is always applied for a new TB. For example, only the CBG of TB #1 that needs retransmission may be transmitted in scheduling unit n + k1, when the process number in the DCI is for retransmission data, and the retransmitted CBG uses the process number at the initial transmission by default.

The sequential positions of all CBGs in the scheduling unit remain unchanged, and the CBG of the newly transmitted TB replaces the sequential position of the CBG that was already correct in the last transmission.

The receiving end equipment can know whether each CBG in one transmission is retransmitted or newly transmitted according to the CBG retransmission indication signaling, and if the CBG is retransmitted, the UE can further deduce which TB in which scheduling unit the CBG initially transmitted belongs to according to the sequence position of the CBG in the scheduling unit and the continuous retransmission times. For example, the receiving end device finds that the first CBG #0 is retransmitted in the scheduling unit n + k2, and can find that the CBG #0 is still the first CBG in the scheduling unit n + k1, and is also retransmitted, which is equivalent to that the retransmission is performed for 2 times at the same sequence position, and the receiving end device finds that the first CBG #0 is originally transmitted in the scheduling unit n, so that the receiving end device can obtain that the first CBG #0 in the scheduling unit n + k2 belongs to the TB #1 (only the TB #1 is transmitted in the scheduling unit n). Therefore, the receiving end equipment can combine the same CBG of the initial transmission and the retransmission for decoding.

The modulation coding information MCS and the resource allocation information in the one DCI are shared as all transport blocks or CBGs in the scheduling unit.

And mapping the CB or the CBG in the resource distributed in the slot according to the principle of frequency domain priority. Therefore, the receiving terminal equipment deduces the concrete resources occupied by each CBG in the allocated resources according to the agreed mapping rule, the size of each CBG, the resource allocation information, the MCS information and the sequence positions of all CBGs.

It is assumed here that the relationship of the scheduling units n, n + k1, and n + k2 is such that n + k1 is the retransmission scheduling unit of n and n + k2 is the retransmission scheduling unit of n + k1.

The above assumptions can be directly or indirectly supported in the following manner.

In the method 1, the retransmission scheduling unit corresponding to the data in the scheduling unit n is configured, for example, at an interval of k1 slots, that is, the retransmission scheduling unit corresponding to the data in the scheduling unit n is n + k1. The configuration may be used by physical layer signaling or RRC messages, or a combination of both. When in combined use, the RRC configures a value set of k1, and then indicates that a specific k1 value is from the value set of k1 through physical layer signaling, for example, DCI.

In the method 2, each DCI for scheduling data may include a process number corresponding to each of a plurality of TBs (or retransmitted CBGs). For example, when the scheduling unit n + k1 schedules the retransmitted CBG (from TB # 1) and the new TB #2 via one piece of DCI, the DCI includes the process number corresponding to the retransmitted CBG (note that it needs to be identical to the process number at the time of initial transmission) and also includes the process number corresponding to the new TB # 2. It is equivalent to indirectly tell the UE from which scheduling unit the retransmitted CBG came.

And in the mode 3, a synchronous HARQ retransmission mechanism is adopted for retransmission.

In mode 4, the retransmitted CBG and the new TB use a shared process number, and at this time, the DCI only includes one process number and is used as the retransmitted CBG and the new TB. For example, the process number configured for TB #1 in scheduling unit n is 1, and the process numbers configured for the retransmitted CBG and the new TB #2 in scheduling unit n + k1 are still 1 (because there is a retransmitted CBG from TB #1, the retransmitted CBG needs to keep consistent with the process number of the initial transmission), so that the new TB #2 shares the process number with the retransmitted CBG from TB # 1. And the UE determines which scheduling units are transmitted or retransmitted before the CBG retransmission through the retransmission times and the process number of the CBG. All CBGs in the scheduling unit remain unchanged with respect to their sequential positions, and the new TB is always transmitted instead of transmitting the correct sequential position of the CBG.

Detailed description of example 10

In this embodiment, a CBG-based ACK/NACK feedback manner is solved, which is beneficial to improving the probability of correctly knowing whether transmitted data is correctly decoded.

Mode A:

for one transport block, the base station configures the UE to always form ACK/NACK according to the transport blocks TB (e.g., each TB forms 1-bit ACK/NACK). The base station receives the ACK/NACK, and if the feedback is NACK, the base station retransmits the TB, and configures or implies the receiving end device to form ACK/NACK according to the code block group CBG (for example, each CBG corresponds to one ACK/NACK) and feeds back the ACK/NACK.

For one transport block, if it is an initial transmission, the UE forms ACK/NACK by TB according to configuration or convention and feeds back. If the transport block is renewed, the UE forms ACK/NACK according to CBG according to configuration or convention and feeds back.

That is, the UE and the base station agree that ACK/NACK is always formed according to CBG for the retransmitted TBs and fed back. The base station configures or agrees with the UE to form ACK/NACK with An CBGs for the nth transmission of a transport block, where An =1 is a first transmission (initial transmission) An =1, and An >1 is obtained when retransmitting (n > 1).

Mode B:

for one transport block, if N bits of ACK/NACK information are formed based on CBGs, the UE and the base station agree that the TB-based ACK information is expressed using one or more states in N bit combinations, and the TB-based NACK information is expressed using a plurality of states in N bit combinations, where different states in the NACK state represent the location of a specific erroneous CBG, for example, when the erroneous CBG is less than K, the location of the specific erroneous CBG is represented by bit 1, and when the erroneous CBG is greater than or equal to K, it is represented by 000, and K < = N. For example, when N =3, half of the 8 states 111, 110, 101, 011 are all indicated as ACK, and half of the 8 states 000, 001, 010, 100 are indicated as NACK (that is, the TB is not decoded correctly), so that the decoding accuracy of the base station is improved, for example, when part of bits in 3 bits are decoded incorrectly, the information that the TB is decoded correctly can also be correctly in terms of probability. Further, for the position of the CBG indicating a specific error with bit 1 in the state indicating NACK, for example, 001 indicates that TB is not decoded correctly and the last CBG is not decoded correctly. In addition, 000 indicates that the TB is not correctly decoded.

Mode C:

for one transport block, if the UE forms ACK/NACK according to CBGs, it should be described which specific CBGs in the TBs are not decoded correctly, and then information on which specific CBGs are not decoded correctly is fed back to the base station. The information fed back by the UE comprises: parameter 1, specifically describing the starting position of the incorrectly decoded CBG; parameter 2, which is optional, describes the number of CBGs that are not decoded correctly or the range of numbers of CBGs that are not decoded correctly. I.e. how many consecutive CBGs are not decoded correctly, starting from the start position of the described incorrectly decoded CBG. The method can be applied to ACK/NACK feedback of the CBG of the punctured eMBB when the URLLC service punctures the eMBB service transmission. Parameter 1 and parameter 2 may be indicated by display or implicit in different states. The combination of parameter 1 and parameter 2 may imply information that brings out TB ACK/NACK.

For example, in a slot of an eMBB, consecutive OFDM symbols are punctured, so that consecutive CBGs will not be decoded correctly by the receiving device, and then feedback information of ACK/NACK may be formed in this manner, for example, parameter 1 indicates a starting CBG that is not decoded correctly, and parameter 2 describes the number of CBGs that are not decoded correctly.

As one possible example, the base station knows the size of the URLLC transport block, and the base station configures the CBG of the eMBB to be equal to the size of the URLLC transport block. At this time, during URLLC transmission, one CBG of eMBB is always knocked out, so that it is always assumed that the number of consecutive incorrectly decoded CBGs (i.e., punctured CBGs) is 1, and this parameter is omitted. At this time, option B can be used.

By adopting the technical scheme, if the UE is allowed to form and send the ACK/NACK based on the CBG or TB, the scheme further provides a transmission mode for supporting the mechanism for switching the CBG or TB to transmit the corresponding ACK/NACK information. The transmission mode can improve the retransmission efficiency and has smaller overhead.
