[0083] FIG. 1 is a diagram of a wireless communication system according to an exemplary embodiment. 1, the wireless communication system is a communication system based on cellular mobile communication technologies. The wireless communication system may include terminals 11 and base stations 12.

[0084] The terminal 11 may be a device that provides the user with the ability to transmit voice and/or data. Terminal 11 may communicate with one or more core networks via a radio access network (RAN, radio access network). The terminal 11 may be an IoT terminal, such as a sensor device, a mobile phone (or cell phone), and a computer with an IoT terminal, such as a desktop, portable, handheld, handheld, embedded computer, or vehicle device, such as a station (STA), a personal unit, subscriber station, mobile station, mobile device, remote station, access point, remote terminal, access terminal, user terminal, user agent, user device or user equipment (UE, user equipment).

Alternatively, the terminal 11 may also be a roadside device such as a street lamp, traffic light, or other roadside device having a wireless communication function.

[0085] Base station 12 may be a network side device in a wireless communication system. The wireless communication system may be a 4th generation (4G) mobile communication system, also known as a long term evolution (LTE) project system. The wireless communication system may also be a 5th generation (5G) mobile communication system, also known as a new radio (NR, new radio) system or a 5G NR system. Alternatively, the wireless communication system may also be a next-generation 5G system. The access network in a 5G system may be referred to as a new generation-radio access network (NG-RAN). The wireless communication system may also be an MTC system.

[0086] In a 4G system, base station 12 is commonly referred to as an evolved base station (eNB). Alternatively, base station 12 may also be a base station (gNB) adapted for a centralized and distributed architecture in a 5G system. When the base station 12 uses a centralized/distributed architecture, it typically includes a central unit (CU, central unit) and at least two distributed units (DU, distributed unit).

The implementation form of the network administration device 13 is not limited to embodiments of the invention.

[0091] Entities involved in embodiments of the invention include, but are not limited to, devices that use the MTC for communication, such as MTC clients, in particular MTC terminals and IoT terminals.

[0092] An application scenario of the embodiments of the invention is that, due to the poor signal coverage in the MTC and the relatively low cost and low processing power of the MTC devices, the MTC uses a transmission block transmission block mechanism in the course of scheduling a plurality of TVs, that is, alternate and retransmission of different TV. In FIG. 2 shows that the TV sequence can be transmitted repeatedly and alternately.

[0093] According to the serial TV transmission method, the transmission end times of each TV are relatively close. According to the HARQ transmission method applied in the corresponding MTC system, as shown in FIG. 3, TV HARQ transmission times overlap, which complicates HARQ processing in a HARQ transmission device such as an MTC client. Due to the performance limitation of the HARQ transmission device, the HARQ transmission device may even become inoperable.

[0094] FIG. 4 shows a flowchart of an HARQ transmission method according to an exemplary embodiment. The HARQ transmission method can be applied to wireless communication devices such as MTC clients.

[0095] The method includes transmitting HARQ for a plurality of different TVs that are transmitted in turn based on different time domain resources.

[0096] The serial transmission of a plurality of different TVs includes periodic transmission of a TV alternate transmission unit (TV alternate transmission unit) until the total number of retransmissions configured for each TV is reached, wherein the TV alternate transmission unit includes N retransmissions different TVs, where N is greater than 0 and less than the configured total number of retransmissions.

[0097] A TV sequencing block includes at least two TVs, and these TVs are sorted in a specific order to form a TV sequencing block.

[0098] A HARQ transmission terminal, eg, an MTC client, transmits HARQ of different TVs based on different time domain resources, which can reduce the overlap of HARQ transmission time intervals of different TVs. The HARQ transmission terminal processes one HARQ in one time domain, and the complexity of HARQ transmission in the time domain by the transmission terminal is reduced. Thus, the processing capability requirement of the HARQ transmission terminal is reduced, the success rate of the HARQ transmission is increased, and the stability of the HARQ transmission terminal is improved. One HARQ may be transmitted over one time domain resource.

[0099] TV is a kind of content block. Different TVs contain different content. According to FIG. 2, the total number of retransmissions for TV is 4. In the TV serial block, TV is retransmitted N times. In FIG. 2 N is 2. The data content of TB1 transmitted all 4 times is the same. The content of data blocks TB1 and TB2 is different. The content of block TB1 transmitted 4 times is the same in each transmission.

[00100] Due to the alternate transmissions, the received powers of the same TV can be accumulated, thus increasing the decoding success rate at the TV receiving terminal.

[00101] In embodiments, HARQ requests for multiple different TVs that are transmitted in turn are transmitted based on different time domain resources, which prevents HARQs of different TVs from occupying the same time domain resource (which can lead to complication due to orthogonal transmission during time area). Thus, the processing complexity for a HARQ transmission terminal in HARQ transmission is reduced, especially for terminals such as MTC transmission terminals with weak processing capabilities, which can reduce the transmission failure rate due to high HARQ transmission complexity and increase the transmission success rate. HARQ.

[00102] In some embodiments, one TV has one HARQ.

[00103] In some embodiments, a single TV that is retransmitted multiple times may have multiple HARQs. If one TV has one HARQ, transmission resources occupied by unnecessary HARQs are reduced, which saves on transmission costs.

[00104] In the serial transmission of TV in FIG. 2, the TV serial block is transmitted twice, and the TV is retransmitted twice in the TV sequential transmission block. The data content of TV that is retransmitted may be the same, for example, the data content of TB1 that is transmitted four times is the same.

[00105] In serial transmission, TV will be retransmitted several times. A HARQ transmission terminal, such as an MTC client, will demodulate a TV received multiple times after receiving a TV transmitted multiple times. the demodulation result is fed back to the TV transmission terminal via HARQ. HARQ includes: acknowledgment (ACK, acknowledgment) and negative acknowledgment of reception (NACK, negative acknowledgment).

[00106] In particular, if the demodulation result is correct, an ACK is returned, and/or if the demodulation result is not correct, NACK is returned.

[00107] As another example, if the demodulation result is correct, no HARQ is sent, and if the demodulation result is not correct, NACK is sent. As another example, if the demodulation result is correct, HARQ is sent, and if the demodulation result is not correct, NACK is not sent. Thus, the HARQ receiving terminal can determine whether the TV was successfully transmitted based on whether the HARQ was received in the predetermined transmission resource.

[00108] Referring to FIG. 2, in alternate retransmission, TB1 is transmitted for the total number of retransmissions. In FIG. 2, the total number of TV retransmissions is 4. The HARQ transmission terminal analyzes TB1 retransmitted 4 times and sends a HARQ to the base station as feedback whether TB1 has been correctly demodulated, and the HARQ indicates the final transmission result of TB1 retransmitted 4 times. In the alternate transmission of TB1 - TB4 in FIG. 2, the HARQ transmission terminal will transmit a total of 4 HARQs corresponding to TB1 to TB4 to the base station.

[00109] Different time domain resources mean that the time domain resources used to return the HARQ of different TVs do not overlap with each other in the time domain.

[00110] Referring to FIG. 5, HARQs of different TVs are transmitted based on different time domain resources, the overlap of HARQ transmission lengths of different TVs is reduced, and since the HARQ transmission terminal only needs to process one HARQ in the same time domain, the time domain HARQ transmission complexity of the HARQ transmission terminal is reduced. Thus, the processing capability requirement of the HARQ transmission terminal is reduced, the success rate of the HARQ transmission is increased, and the stability of the HARQ transmission terminal is improved.

[00111] In some embodiments, different TV HARQs are transmitted on the PUCCH based on different time domain resources.

[00112] The HARQ is carried on the PUCCH for transmission. Thus, HARQ transmission in different time domains can be performed by calling PUCCH on different time domain resources.

[00113] In some embodiments, different TV HARQ transmission on the PUCCH based on different time domain resources is possible in the following six modes.

[00114] In the first mode, HARQs of different TVs are transmitted on the PUCCH based on different time domain resources using the same frequency domain resources.

[00115] In the second mode, HARQs of different TVs are transmitted on the PUCCH based on different time domain resources using the same code domain resources.

[00116] In the third mode, HARQs of different TVs are transmitted on the PUCCH based on different time domain resources using the same frequency domain resources and the same code domain resources.

[00117] In the fourth mode, HARQs of different TVs are transmitted on the PUCCH based on different time domain resources using different frequency domain resources.

[00118] In the fifth mode, HARQs of different TVs are transmitted on the PUCCH based on different time domain resources using different code domain resources.

[00119] In the sixth mode, HARQs of different TVs are transmitted on the PUCCH based on different time domain resources using different frequency domain resources and different code domain resources.

[00120] The transmission resources are configured for the PUCCH, and these transmission resources can be classified into time domain resources, frequency domain resources, and code domain resources. For example, different time domain resources correspond to different PUCCH transmission times.

[00121] Different frequency domain resources correspond to different transmission frequency subbands or PUCCH carriers.

[00122] Different code domain resources indicate that the PUCCH resources can be divided into different formats.

[00123] The HARQ transmission needs to satisfy only the difference in the time domain, which can prevent the HARQ transmission time intervals of different TVs from overlapping and reduce the workload of the HARQ transmission terminal. Thus, HARQ of different TVs may be transmitted on the PUCCH of the same frequency domain, the same code domain, or the same frequency and code domain.

[00124] In some embodiments, a HARQ transmission for a plurality of different TVs includes sequential transmission of M HARQ retransmissions of each TV, where M is the total number of HARQ retransmissions of each TV.

[00125] In serial TV transmission, one TV corresponds to one HARQ, and each HARQ can only be transmitted once. According to FIG. 5, four HARQs corresponding to TB1 to TB4 are transmitted once in different time domains, respectively.

[00126] Referring to FIG. 6, each HARQ may also be transmitted M times, and the retransmitted HARQs may be demodulated together, which improves the reception and demodulation success rate of the base station. In FIG. 6, M is 4, and P1, P2, P3, and P4 represent the HARQs of blocks TB1, TB2, TB3, and TB4, respectively. P1, P2, P3 and P4 are retransmitted 4 times.

[00127] In some embodiments, HARQs of different TVs are transmitted in turn.

[00128] The HARQ of each TV may be transmitted repeatedly and in turn. The HARQ sequencing block is established by HARQ requests of different TVs based on the sequence of different TVs in the TV sequencing block. The HARQ interleaved transmission block is transmitted multiple times.

[00129] In some embodiments, the HARQ sequencing block is transmitted periodically until the total number of retransmissions configured for each HARQ is reached. The HARQ sequencing block includes X retransmissions of each HARQ, where X is greater than 0 and less than the configured total number of retransmissions for each HARQ.

[00130] The HARQ of each TV may be transmitted alternately and repeatedly. In particular, the HARQ requests of different TVs can be used to establish a HARQ sequencing block based on the sequence of each TV in the TV sequencing block. The HARQ sequencing block may be transmitted multiple times. One HARQ may be retransmitted X times in one HARQ IC. According to FIG. 7, the HARQ corresponding to TB1 may be retransmitted X times, where X is 2, and then the HARQs of TB2, TB3, and TB4 may be retransmitted X consecutive times. At the end of X retransmissions of the HARQ requests of all TVs, the HARQ requests of all TVs are retransmitted again until a predetermined termination condition is met. For example, the termination condition may be that the number of HARQ transmissions reaches a predetermined total number of retransmissions. In FIG. 7, the total number of HARQ retransmissions is 4. The HARQ sequence of different TVs in the HARQ sequencing block may be set according to the sequence of different TVs corresponding to these HARQs in the TV sequencing block.

[00131] In some embodiments, the number of HARQ retransmissions in a HARQ serial block is determined based on the received high level signaling; or the number of HARQ retransmissions in the HARQ sequencing block is determined based on the number of TV retransmissions in the TV sequencing block; or the number of HARQ retransmissions in the HARQ sequencing block is determined based on the PUCCH frequency hopping block.

[00132] The number of HARQ retransmissions is determined based on the received high layer signaling. It is also possible to determine the number of HARQ transmissions based on the number of TV transmissions in the serial transmission process, for example, the number of TV transmissions is equal to or proportional to the number of HARQ transmissions.

[00133] The frequency hopping unit is configured to configure the number of consecutive PUCCH retransmissions in the frequency domain. The size of the frequency hopping block can be configured by the base station. For example, the size of the hopping block is configured to be Q times. The physical meaning is that after Q PUCCH retransmissions in a certain frequency band, it is necessary to move to another frequency band and perform M PUCCH retransmissions in another frequency band. Thus, the number of HARQ transmissions in a HARQ sequencing block can be set equal to the hop block size, that is, X is equal to Q.

[00134] In some embodiments, different HARQs are transmitted using different time domain resources after the first slot in which the transmission of the first of the TV ends. Alternatively, different HARQs are transmitted using different time domain resources after the second slot in which the transmission of the last TV ends.

[00135] In the HARQ example of FIG. 6, HARQ transmission may start 4 ms after the end of TB1. In the HARQ example in FIG. 7, the entire serial transmission may take the transmission end time of the last TV as a reference, and start transmission, for example, 4 ms after the end of the transmission of the last TV. Thus, time can be reserved for transmitting the HARQ configuration to satisfy the sequencing requirement.

[00136] HARQs of different TVs are transmitted based on different time domain resources to reduce overlap of HARQ transmission times of different TVs. The HARQ transmission terminal only needs to process one HARQ in the same time domain, which reduces the complexity of the HARQ transmission terminal in the time domain in HARQ transmission, reduces the processing capacity requirement of the HARQ transmission terminal, increases the success rate of the HARQ transmission, and improves the stability of the HARQ transmission terminal.

[00137] Referring to FIG. 8, a HARQ transmission method is proposed in an exemplary embodiment. The method can be applied to wireless communication devices such as MTC clients. The method includes the following.

[00138] In block 801, HARQ information is generated by performing predetermined encoding for HARQ of a plurality of different TVs that are transmitted in turn.

[00139] In block 802, HARQ information is transmitted.

[00140] Sequential transmission of a plurality of different TVs includes periodically transmitting a TV sequencing block until the total number of retransmissions configured for each TV is reached, wherein the TV sequencing block includes N retransmissions of different TVs, where N is greater than 0 or less than the configured total number of retransmissions.

[00141] A TV sequencing block includes at least two TVs, and these TVs are sorted in a specific order to form a TV sequencing block.

[00142] A HARQ transmission terminal, such as an MTC client, demodulates and decodes a TV after receiving different TVs, and confirms whether the TVs are successfully decoded, and then encodes the HARQ of each TV to obtain HARQ information, and transmits the HARQ information, which can reduce transmission time overlap HARQ. Thus, the HARQ processing complexity of the HARQ transmission terminal is reduced, the processing capability requirement of the HARQ transmission terminal is reduced, the transmission success rate of HARQ information is increased, and the stability of the HARQ transmission terminal is improved. One HARQ may be transmitted in one time domain resource.

[00143] TV is a kind of content block. Different TVs contain different data content. According to FIG. 2, the total number of retransmissions for TV is 4. In the TV serial block, TV is retransmitted N times. In FIG. 1 N is 2. The content of TB1 transmitted all 4 times is the same. The content of TB1 and TV2 are different. The content of TB1 transmitted 4 times is the same.

[00144] In some embodiments, one TV has one HARQ.

[00145] Of course, in other embodiments, a single TV that is retransmitted multiple times may have multiple HARQs. If one TV has one HARQ, then the transmission resources occupied by unnecessary HARQs are reduced, which saves transmission costs.

[00146] In the serial transmission of TV in FIG. 2, the TV serial block is transmitted twice, and the TV is retransmitted twice in the TV sequential transmission block. The TV content that is retransmitted is the same, for example, the TB1 content that is transmitted four times is the same.

[00147] In serial transmission, TV will be retransmitted several times. The HARQ transmission terminal will demodulate the TV received multiple times after receiving the TV transmitted multiple times. The demodulation result is sent back to the TV transmission terminal via HARQ. HARQ includes ACK and NACK.

[00148] In particular, if the demodulation result is correct, an ACK is returned, and/or if the demodulation result is not correct, NACK is returned.

[00149] Referring to FIG. 2, TB1 is transmitted 4 times in alternate retransmissions. The HARQ transmission terminal analyzes TB1 retransmitted 4 times and sends a HARQ to the base station to receive feedback whether TB1 is demodulated correctly. In the alternate transmission of TB1 - TB4 in FIG. 2, the HARQ transmission terminal will transmit a total of 4 HARQs corresponding to TB1 to TB4 to the base station.

[00150] The HARQs of the TV set may be pre-coded to obtain HARQ information encoded by the HARQ set. The content of the HARQ information is determined by a predetermined coding that can represent results of demodulation of TV blocks, such as whether TVs are correctly demodulated.

[00151] A single HARQ information can be used, so that the HARQ transmission time overlap can be reduced in the process of transmitting the HARQ information. Thus, the complexity of HARQ processing by the HARQ transmission terminal is reduced, the workload of the HARQ transmission terminal is reduced, and the stability of the HARQ transmission terminal is improved.

[00152] In some embodiments, the HARQ information is obtained by performing a bitwise AND operation on the HARQ of a plurality of different TVs.

[00153] For example, as shown in FIG. 9, the HARQ corresponding to each of TB1 to TB4 may be bitwise ANDed to obtain HARQ information representing the general demodulation situation of TB1 to TB4. For example, if the HARQ for TB1 is "0", it means that the demodulation has failed. If the HARQ of each of TB2, TB3 and TB4 is "1", it means that the demodulation was successful. Then, after bitwise ANDing for all HARQs, HARQ information "O" is obtained. After the base station receives the HARQ information, it will be known that at least one of TB1 - TB4 failed to demodulate, and TB1 - TB4 can be transmitted again.

[00154] In some embodiments, HARQ information modulated by BPSK is transmitted.

[00155] BPSK may be used to modulate the HARQ information to satisfy PUCCH requirements, and the HARQ information may be carried on the PUCCH for transmission.

[00156] HARQs are encoded into one HARQ information and transmitted via PUCCH, which avoids the problem of PUCCH time overlap carried by HARQ and reduces the workload of the HARQ transmission terminal.

[00157] In some embodiments, different HARQ groups are obtained by performing a bitwise AND operation based on the groups for HARQ of a plurality of different TVs, and HARQ information is obtained by combining the different HARQ groups.

[00158] For example, HARQ of different TVs can be classified into two groups. According to FIG. 10, the HARQ corresponding to each of TB1 - TB4 can be assigned to one of two groups. HARQ for TB1 and HARQ for TB2 are combined into one group, and a bitwise logical AND operation is performed to obtain a 1-bit result. HARQ for TB3 and HARQ for TB4 are combined into another group, and a bitwise AND operation is performed to obtain a 1-bit result. The two groups are combined to generate 2-bit HARQ information by combining two 1-bit results. For example, if the HARQ for TB1 is "0", it means demodulation has failed. If the HARQ of each of TB2, TB3 and TB4 is "1", it means that the demodulation was successful. Then, a bitwise AND operation is performed on HARQ TB1 and HARQ TB2 to obtain HARQ information "1". After the bitwise AND operation is performed for HARQ TB3 and HARQ TB4, HARQ information "1" is obtained. After the base station receives the HARQ information, it may be known that at least one of TB1 and TB2 failed to be demodulated, and TB1 and TB2 may be retransmitted. You can pre-assign a plurality of TVs to form a group.

[00159] In some embodiments, HARQ information modulated by QPSK is transmitted.

[00160] For 2-bit HARQ information, QPSK may be used to modulate the HARQ information to satisfy PUCCH requirements, and the HARQ information is carried on the PUCCH for transmission.

[00161] Multiple HARQs are encoded into one HARQ information and transmitted via PUCCH, which avoids the problem of PUCCH time overlap carried by HARQ and reduces the workload of the HARQ transmission terminal.

[00162] In some embodiments, the PUCCH is used to transmit HARQ information, and the HARQ information is transmitted on the PUCCH after the third time interval after the end of the transmission of the last TV.

[00163] The transmission time of the HARQ information is based on the end time of the transmission of the last TV as a reference, and the transmission starts after, for example, 4 ms after the transmission of the last TV. In addition, some time may be reserved for HARQ encoding.

[00164] Thus, it can be ensured that the HARQ information is transmitted at the end of the transmission of all TVs, and the occurrence of the uncertainty of the consequences is reduced.

[00165] A single HARQ information can be used, whereby during the transmission of HARQ information, the HARQ time overlap for TV is reduced, the complexity of HARQ processing by the HARQ transmission terminal, and the processing load in the HARQ transmission terminal is reduced to improve the stability of the HARQ transmission terminal.

[00166] FIG. 11, a HARQ transmission method is proposed in an exemplary embodiment, which can be applied to a base station of the MTC system, but is also limited to the base station of the system. The method includes the following.

[00167] In block 1101, HARQ information is received, which is obtained by performing predetermined encoding for HARQ of a plurality of different TVs that are transmitted in turn.

[00168] In block 1102, a decoding sequence is obtained by decoding the HARQ information based on a demodulation mode corresponding to a predetermined encoding.

[00169] In block 1103, the demodulation states of the plurality of different TVs are determined based on the decoding sequence.

[00170] Sequential transmission of a plurality of different TVs includes periodically transmitting a TV sequencing block until the total number of retransmissions configured for each TV is reached, wherein the TV sequencing block includes N retransmissions of different TVs, where N is greater than 0 or less than the configured total number of retransmissions.

[00171] A TV sequencing block includes at least two TVs, and these TVs are sorted in a specific order to form a TV sequencing block.

[00172] A TV serial transmission block may be transmitted by a TV transmission terminal, such as a base station. A HARQ transmission terminal, such as an MTC client, after receiving a plurality of different TVs, decodes the TV, obtains HARQ information from each TV's HARQ by a predetermined coding, and transmits the HARQ information after being modulated by a modulation method corresponding to the predetermined coding, which can reduce HARQ overlap over time, reduce the complexity of HARQ processing at the HARQ transmission terminal, and reduce the performance requirements of the HARQ transmission terminal. In turn, the success rate of HARQ information transmission is increased, and the stability of the HARQ transmission terminal is increased. HARQ may be transmitted over a time domain resource. The HARQ information obtained by encoding may represent the demodulation states of a plurality of different TVs.

[00173] A HARQ transmission terminal, such as a base station, decodes the received HARQ information based on a demodulation method corresponding to a predetermined encoding to obtain a decoding sequence. The decoding sequence represents the demodulation states of different TVs.

[00174] In some embodiments, if the decoding sequence is a predetermined sequence, it is judged that different TVs have been successfully received.

[00175] The predetermined sequence may be determined based on the predetermined encoding method. If "1" as a result of the predetermined encoding indicates that different TVs are successfully received, the predetermined sequence may be set to "1".

[00176] In particular, with reference to FIG. 9, a HARQ transmission terminal, eg, an MTC client, may perform predetermined encoding for the HARQs corresponding to TB1 to TB4, eg, AND, to obtain HARQ information representing the general demodulation states of TB1 to TB4. HARQ may use "0" to indicate failed demodulation and use "1" to indicate successful demodulation. For example, if the HARQ of each of TB1, TB2, TB3, and TB4 is "1", which means that demodulation is successful, then a bitwise AND operation is performed on all HARQs to obtain HARQ information of "1", which means that TB1, TB2 , TV3 and TV4 are successfully demodulated. The predetermined sequence is set to "1".

[00177] When the predetermined sequence is "1", the HARQ transmission terminal receives the HARQ information and demodulates to obtain a decoding sequence "0" that does not match the predetermined sequence, it is considered that at least one TV is not demodulated successfully.

[00178] In some embodiments, if the decoding sequence is not a predetermined sequence, it is judged that at least one TV was not successfully demodulated.

[00179] If the sequence in FIG. 9 is set to "1" in advance, when one of the HARQs for TB1, TB2, TB3, and TB4 is "0", HARQ information "0" is obtained after the bitwise AND operation is performed for all HARQs, indicating demodulation failure. at least one of TB1, TB2, TB3 and TB4.

[00180] The HARQ transmission terminal receives the HARQ information and demodulates to obtain a decoding sequence "0" that does not match the predetermined sequence, and it is considered that at least one TV has not been successfully demodulated.

[00181] In some embodiments, if at least one TV failed to be demodulated, the entire TV sequencing block is retransmitted.

[00182] After deciding that at least one TV in the TV sequencing block failed to be demodulated, the TV sequencing block may be retransmitted.

[00183] In some embodiments, the decoding sequence is obtained by decoding the HARQ information based on the BPSK or QPSK demodulation mode.

[00184] The predetermined encoding may perform a bitwise AND operation for HARQ of different TVs to obtain 1-bit HARQ information; or allows to obtain different HARQ groups by bitwise ANDing based on the groups for HARQ of a plurality of different TVs, and combine different HARQ groups to obtain 2-bit HARQ information.

[00185] 1-bit HARQ information generated after predetermined encoding may be transmitted according to the BPSK modulation method. Thus, the BPSK demodulation method is used to decode the HARQ information by the HARQ receiving terminal.

[00186] 2-bit HARQ information generated after predetermined encoding may be transmitted according to the QPSK modulation method. Thus, the QPSK demodulation method can be used to decode HARQ information by the HARQ receiving terminal.

[00187] In embodiments, for HARQ of a plurality of different TVs that are transmitted in turn, the HARQ receiving terminal receives HARQ information that is obtained by predetermined encoding for HARQ of the plurality of different TVs, and then determines the demodulation states of the different TVs, which prevents the HARQ of the different TVs occupy the same time domain resource (which may lead to complexity due to time domain orthogonal transmission), thereby reducing the processing complexity in the HARQ transmission terminal in HARQ transmission, especially for terminals having weak processing capabilities, such as MTC terminals. Thus, the transmission error due to the high complexity of the HARQ transmission can be reduced, and the success rate of the HARQ transmission can be increased.

[00188] Several specific examples are provided below in conjunction with any of the above embodiments.

[00189] Example 1, HARQ serial transmission

[00190] The essence of the solution is that only one TV is allowed to transmit HARQ at a time.

[00191] Referring to FIG. 6, during the alternate transmission period, the HARQ of the first TB still follows the original sequence, for example, the HARQ may be returned starting 4 ms after the end of TB1.

[00192] HARQ for TV after TB1 can be performed only after the end of the HARQ transmission of the current TV.

[00193] Example 2, HARQ serial transmission

[00194] The essence of the solution is that a single HARQ transmission is allowed at the same time.

[00195] Similar to the idea of the TV serial transmission mechanism, the PUCCH of the HARQ carrier corresponding to each TV is repeated in turn. According to FIG. 7, first the HARQ corresponding to TB1 may be retransmitted S times, and then the HARQ corresponding to TB2 may be transmitted sequentially until the HARQ corresponding to the last TB is retransmitted S times. After N retransmissions of each TV are completed, S retransmissions may be performed again until the HARQs corresponding to all TVs reach the configured number of retransmissions. The S retransmissions of each HARQ included in each sequencing transmission is defined as the size of the HARQ sequencing block. The HARQ interleaved block size S may be determined as follows.

[00196] Method 1: high level signaling configuration.

[00197] Method 2: A correspondence relationship is established between HARQ sequencing block sizes and downlink TV sequencing block sizes. The HARQ queuing block size S may be derived according to the configured queuing block size of the downlink TV. For example, S may be set equal to the size of the TV serial transmission block.

[00198] Method 3: Size S may be determined based on other PUCCH transmission characteristics. For example, S is equal to the PUCCH frequency hopping block size.

[00199] All serial HARQ transmission relies on the end time of the transmission of the last TV as a reference point, and the transmission starts after a certain interval, for example, 4 ms, after the transmission of the last TV.

[00200] Example 3: Linked HARQ transmission.

[00201] Here, the HARQs of multiple TVs can be associated and then transmitted on the same PUCCH. The binding method may be as follows. According to FIG. 9, after performing a logical AND operation for the HARQ of all TVs, 1 bit is generated, which is then transmitted in the PUCCH by BPSK modulation. Or, according to FIG. 10, multiple scheduled TVs are classified into two groups, and the HARQs for the TVs in each group are logically summed to form 1 bit, while a total of 2 bits can be generated for feedback, and then transmitted on the PUCCH by QPSK modulation.

[00202] The post-association HARQ time may use the transmission end time of the last TV as a reference point, and the transmission will start after a certain interval, for example, 4 ms after the transmission of the last TV.

[00203] With serial transmission, the traditional one-to-one feedback is no longer supported, and only transmission linking HARQ is supported. Thus, the HARQ-binding transmission is used when configuration is not required, and the HARQ-binding transmission is the default mode of the interleaved transmission feedback.

[00204] Embodiments of the invention also provide an apparatus for transmitting HARQ. In FIG. 12 shows a structural diagram of an apparatus 100 for transmitting HARQ according to some embodiments of the invention. According to FIG. 12, the device includes a first transmission module 110.
