Description

Uplink transmission method and device

Technical Field

The present disclosure relates to the field of communications technologies, and in particular, to an uplink transmission method and apparatus, an electronic device, and a computer-readable storage medium.

Background

In order to improve the reliability of uplink transmission, coverage enhancement may be achieved by a method of repeating transmission. For example, for an uplink physical shared channel PUSCH, a PUSCH repetition scheme may be used to perform PUSCH repetition, so that a network device such as a base station may combine received PUSCH signals repeated multiple times, thereby obtaining a higher signal-to-noise ratio.

However, in the related art of the PUSCH repetition type a, although nominally 16 repetitions may be configured, for some TDD (Time-division Duplex) systems with a relatively large number of downlink timeslots, for example, downlink timeslot DL: uplink timeslot UL being 7:3 or 4:1, due to a large amount of unavailable resources, PUSCH repetition may be cancelled, so that the actual number of transmissions is far less than the number of nominally configured repetitions. Thus, for some cases with poor coverage, the uplink coverage performance may be severely degraded. In addition, for some cases with better coverage, too many repeated transmissions also cause resource waste.

In view of the above, how to flexibly adjust the uplink retransmission becomes an urgent problem to be solved.

Detailed Description

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

In the uplink, coverage enhancement can be achieved by a method of repeated transmission. For example, in the technical solution of PUSCH repetition type a, the terminal may be configured with the number of repetitions of uplink transmission, so that the terminal performs transmission according to the configured number of repetitions. For example, according to the related art of PUSCH repetition type a, the terminal may be configured with the repetition number N (number of repetition), and then the terminal considers that the terminal is an effective available resource in the duration of the following N slots and N × L (L represents the number of symbols in each slot), so that the terminal may perform PUSCH transmission based on the effective available resource. Of course, here, the PUSCH is merely taken as an example, and in the related art, the same method may be used for PUCCH.

In the TDD system, the N time slots in the available resources include an uplink time slot and a downlink time slot, and although the terminal can nominally transmit in the next N time slots, the terminal can only transmit once in each uplink time slot by using the uplink time slot, so that the number of times that the terminal actually repeats transmission is much less than the configured number of times of repetition N. For example, for a frame with a "DDDSU" structure, the ratio of the downlink time slot DL to the uplink time slot UL is 4:1, that is, the uplink time slot is 1/5, so that the actual transmission number of the terminal is 1/5 of the configured repetition number N.

Therefore, when the terminal is instructed to perform uplink repeat transmission based on the number of repetitions configured in the related art, the actual number of transmissions is much smaller than the configured number of repetitions. And for some terminals with poor coverage, the uplink coverage performance is seriously reduced.

In addition, for some terminals with better coverage, the transmission is performed according to the repetition number of the current configuration, which may also cause too many repetitions, resulting in resource waste.

In view of this, an embodiment of the present disclosure provides an uplink transmission method, in which the number of repetitions of uplink transmission can be flexibly adjusted, and resource waste is avoided on the basis of ensuring coverage enhancement.

Fig. 1 is a schematic flow chart diagram illustrating an uplink transmission method according to an embodiment of the present disclosure. The uplink transmission method shown in this embodiment may be applied to a terminal, where the terminal includes, but is not limited to, an electronic device such as a mobile phone, a tablet computer, a wearable device, a sensor, and an internet of things device. The terminal may communicate with a base station as a user equipment, and the base station includes but is not limited to a 4G base station, a 5G base station, and a 6G base station. In an embodiment, the base station may be a base station to which the uplink transmission method described in any subsequent embodiment is applied.

As shown in fig. 1, the uplink transmission method may include the steps of:

in step S101, a repetition number update instruction transmitted by the base station is received.

In one embodiment, the base station may send a repetition update indication to the terminal. The base station may send the update indication of the repetition number to the terminal in various ways, for example, the update indication may be carried in a system message, DCI (Downlink Control Information), and the like.

In an embodiment, the terminal may receive an update indication of the number of repetitions sent by the base station, for example, may receive a system message, DCI, or the like, and parse the update indication of the number of repetitions.

In step S102, the number of repetitions of uplink transmission is updated based on the number of repetitions update indication and the currently configured number of repetitions of uplink.

In one embodiment, the base station may configure the terminal with a repetition number for uplink transmission in advance, for example, 8 times, 16 times, and the like, and the repetition number is denoted as N hereinafter for convenience of description. In the related art, according to the repetition number N of the current configuration, the terminal may perform transmission using the subsequent N time slots, that is, perform uplink transmission once in each uplink time slot in the uplink time slots in the subsequent N time slots. For example, if the currently configured number of transmissions is 16, if the subsequent 16 time slots include 3 uplink time slots, the terminal may perform 3 uplink transmissions in the 3 uplink time slots.

In one embodiment, after receiving the update indication of the number of repetitions sent by the base station, the terminal may update the number of repetitions of the uplink transmission based on the update indication of the number of repetitions and the currently configured number of repetitions of the uplink. Wherein, the uplink may include at least one of PUSCH and PUSCH, that is, updating the repetition number of the uplink includes: updating at least one of the PUSCH and the number of repetitions of the PUSCH. Thus, the terminal may perform uplink transmission according to the updated repetition number, e.g., the terminal may increase or decrease the number of uplink transmissions.

It should be noted that, in the foregoing embodiment, the update indication of the repetition number sent by the base station is indication information of semi-persistent scheduling, and a subsequent terminal may periodically perform uplink retransmission according to the updated repetition number, instead of performing single configuration only for current transmission of the terminal.

In one embodiment, the above method for indicating the number of repetitions update may be applied to the downlink, for example, the number of repetitions of the PDCCH and the PDSCH.

According to the embodiment shown in fig. 1, the base station may flexibly instruct the terminal to update the number of times of repeated transmission on the uplink through the repetition number update indication, for example, the number of transmissions may be reduced in the case of good transmission, and the number of transmissions may be increased in the case of poor transmission. Therefore, the terminal can flexibly adjust the repetition times of the transmission uplink, and avoid resource waste on the basis of ensuring the transmission reliability.

In the embodiments of the present disclosure, the indication of the number of times of repetition update may include various different forms, which are exemplified below with reference to two specific embodiments.

Example 1: the indication of the number of repetitions update includes a number of coefficients.

In one embodiment, the number of times coefficient may be a coefficient of the number of repetitions of the current configuration. For convenience of description, the degree coefficient may be referred to as a hereinafter. In one embodiment, the number coefficient a may be included in the update indication of the number of repetitions sent by the base station, and the terminal may update the number of repetitions for uplink transmission according to the number coefficient a and the currently configured number of repetitions N, for example, the number of repetitions may be increased, decreased, or unchanged.

In one embodiment, the updated number of repetitions may be the product a × N of the number coefficient a and the currently configured number of repetitions N. For example, when the number coefficient a is smaller than 1, the terminal decreases the number of repetitions; when the frequency coefficient is larger than 1, the terminal increases the repetition frequency; when the number coefficient a is equal to 1, the terminal keeps the repetition number unchanged.

It should be noted that, taking the product of the number coefficient a and the repetition number N as the updated repetition number is merely an example, and in practical applications, the repetition number may also be updated by other calculation methods, for example, the product of the square of the number coefficient and the repetition number, and the like.

It should be noted that, in this embodiment, the base station carries the number coefficient a in the indication of updating the number of repetitions, instead of directly carrying the new number of repetitions N'. On one hand, if the carried repetition number N' is greater than the predefined maximum repetition number, the TDRA (time domain resource allocation) table needs to be modified, and the adoption of the number coefficient can avoid the corresponding modification of the TDRA table and avoid the influence on the table overhead; on the other hand, if the number of repetitions N' carried is large, the value may exceed the size of the indication information, for example, if DCI is used to carry the indication information, the available indication bits in the DCI are limited, and may not carry an excessively large value, and the problem of excessively large indication information may be avoided by using the number coefficient.

In one embodiment, the method for determining the above-mentioned coefficient of times a by the base station also includes multiple methods, which are exemplarily described by three embodiments below.

Example 1.1: the base station determines the number coefficient a according to the uplink transmission quality of the terminal.

In one embodiment, the base station may determine the number of times coefficient according to the uplink transmission quality of the terminal. For example, the base station may use SNR (Signal Noise Ratio), MCL (Minimum Coupling Loss), and the like of the terminal as the uplink transmission quality.

In one embodiment, the base station may preset a preset threshold and then determine the number coefficient according to the result of comparing the uplink transmission quality with the preset threshold. For example, the base station may preset a first preset threshold and a second preset threshold, and the first preset threshold may be higher than or equal to the second preset threshold.

In one embodiment, in response to the uplink transmission quality being above a first preset threshold, determining a number coefficient indicates that the terminal decreases the uplink repetition number; or, in response to the uplink quality being lower than a second preset threshold, determining that the number coefficient instructs the terminal to increase the uplink repetition number.

In an embodiment, the base station may preset a preset candidate coefficient, and if the base station determines that the repetition number of the currently configured uplink needs to be updated, the base station may determine the number coefficient as the preset candidate coefficient; or, the base station may preset a plurality of preset candidate coefficients, and if the base station determines that the repetition frequency of the currently configured uplink needs to be updated, the base station may select the preset candidate coefficients according to an actual situation, for example, determine the frequency coefficient as one of the preset candidate coefficients.

Taking the example that the base station indicates the terminal to take the product of the number coefficient a and the currently configured repetition number N as the updated repetition number, the base station preset candidate number coefficient may include {0,0.5,1,2,4,8 }. In response to the uplink transmission quality being higher than a first preset threshold, the base station may determine that a number of times coefficient a is less than 1 to instruct the terminal to reduce the uplink repetition number; or, in response to the uplink transmission quality being lower than a second preset threshold, the base station may determine that the number coefficient a is greater than 1 to instruct the terminal to increase the uplink repetition number; alternatively, if the base station determines that the number of repetitions of the terminal does not need to be updated, the number coefficient a may be determined to be 1.

In one embodiment, the base station may set a minimum transmission quality threshold, for example, may set a second preset threshold as the minimum transmission quality threshold. When the base station determines that the uplink transmission quality is lower than the second preset threshold, the base station may determine the frequency coefficient according to a distance between the uplink transmission quality and the second preset threshold, for example, may calculate a difference between the uplink transmission quality and the second preset threshold, and then determine the frequency coefficient according to a preset corresponding relationship between the difference and the frequency coefficient. Taking the SNR as the transmission quality, for example, if the SNR of the uplink transmission of the terminal is 5dB away from the second preset threshold, the coefficient of the number of times may be configured to be 2. Of course, this is only an exemplary illustration, in practical applications, the base station may also determine the number coefficient by other methods, and this embodiment is not limited in particular.

Thus, example 1.1 is completed. According to embodiment 1.1, the base station may determine a number coefficient according to the uplink transmission quality of the terminal to indicate the terminal update repetition number. Therefore, when the uplink transmission quality of the terminal is better, the repetition times can be reduced so as to save resources; when the uplink transmission quality of the terminal is poor, the repetition times can be increased to realize coverage enhancement and improve the reliability of information transmission.

Example 1.2: the base station determines a frequency coefficient based on a reception result of the preset amount of information transmitted by the terminal.

In one embodiment, the base station may determine a preset number, for example, 1,5,10, etc., and then determine the number coefficient according to the reception result of the preset number of messages transmitted by the terminal. For example, the base station may count the reception results of the information transmitted from the terminal, and then determine a combined result according to the reception results of the information, thereby determining the number coefficient.

In one embodiment, in response to a preset number of successful receptions of information sent by the terminal, determining that the number coefficient indicates that the terminal decreases the number of uplink repetitions; or, in response to a preset number of information reception failures transmitted by the terminal, determining that the number of times coefficient instructs the terminal to increase the uplink repetition number.

In one embodiment, the base station may set one or more preset candidate coefficients in advance, similar to embodiment 1.1 described above. The base station may determine the number coefficient as the preset candidate coefficient, or the base station may determine the number coefficient as one of the plurality of preset candidate coefficients.

In one embodiment, the determining the number coefficient indicates to the terminal to decrease the uplink repetition number comprises: for each piece of the preset amount of information, determining the number of terminal repetition times corresponding to the piece of information which is successfully received; and determining a frequency coefficient based on the repetition frequency respectively corresponding to each piece of information after successful receiving.

For example, the base station may set a preset information quantity M, then count the reception results of the continuous M pieces of information, and if the information reception is successful, record the number of times of repetition sent by the terminal when the information reception is successful; and if the receiving fails, recording the repeated times of the configuration. Thus, the base station can determine the number of times coefficient according to the reception result of the M pieces of information.

For example, if all M pieces of information are successfully received, the base station may determine the number coefficient according to the number of repetitions of the terminal transmission when the M pieces of information are successfully received. Taking M as an example of 5, if the base station successfully receives 5 pieces of information, the number of times coefficient may be determined according to the number of times of terminal repetition when the 5 pieces of information are successfully received, for example, an average value of the number of times of repetition corresponding to the successful reception of the 5 pieces of information and a ratio of the currently configured number of times of repetition are used as the number of times coefficient; or the maximum value of the repetition times corresponding to the successful receiving of the 5 pieces of information and the ratio of the currently configured repetition times are used as a time coefficient and the like.

For example, if there is a reception failure in M pieces of information, the base station may instruct the terminal to increase the repetition number by a number coefficient, for example, a configuration number coefficient a is 2, a is 4, or the like. It should be noted that, after the repetition number is updated, the repetition number can still be updated by the method of the present embodiment.

Thus, example 1.2 was completed. According to embodiment 1.2, the base station may determine the number coefficient based on the reception result of the information transmitted by the reception terminal. When the base station successfully receives the information sent by the terminal, the repetition times of terminal transmission can be reduced so as to save resources; when the base station fails to receive the information sent by the terminal, the number of times of repetition of the terminal transmission can be increased to improve the reliability of the information transmission.

Example 1.3: the base station determines a number of times coefficient based on a ratio of uplink to downlink in an uplink TDD timeslot configuration.

In one embodiment, the base station may determine the ratio of UL in the TDD frame according to the ratio of UL to DL in the uplink TDD timeslot configuration, and then determine the number of times coefficient according to the ratio. Taking the product of the number coefficient a and the repetition number N as the updated repetition number as an example, the inverse of the UL fraction may be used as the number coefficient. For example, for a frame with a "DDDSU" structure, if the ratio of the downlink time slot DL to the uplink time slot UL is 4:1, that is, the uplink time slot is 1/5, the time coefficient may be determined to be the inverse of 1/5 (that is, 5).

Therefore, based on the repetition number N of the current configuration before updating, the terminal can utilize the uplink time slot in the subsequent N time slots to carry out uplink repeated transmission; based on the updated repetition number a × N, the terminal may perform uplink transmission using an uplink timeslot in the subsequent a × N timeslots, where a is an inverse of the occupancy of the uplink timeslot, and the number of uplink timeslots in the subsequent a × N timeslots is N, so that the terminal may implement N uplink transmissions.

Thus, example 1.3 is completed. According to the embodiment 1.3, the base station determines the number coefficient based on the ratio of the uplink to the downlink in the uplink TDD time slot configuration, and the number of times of the terminal repeated transmission reaches the configured number of times of repetition through the number coefficient, thereby realizing coverage enhancement and ensuring the transmission reliability.

Example 2: the number of repetitions update indication is used to instruct the terminal to determine one or more uplink timeslots for uplink transmission based on the number of repetitions of the currently configured uplink.

In one embodiment, after receiving the repetition number update indication, the terminal may determine one or more uplink timeslots based on the updated repetition number; repeating the transmission for the uplink at the one or more uplink time slots.

Taking the currently configured number of repetitions in the terminal as N as an example, in the related art, according to the currently configured number of repetitions N, the terminal may perform transmission using the subsequent N time slots, that is, perform transmission in the uplink time slot in the subsequent N time slots. According to this embodiment, the configured number of repetitions may still be N, but the terminal determines N uplink timeslots according to the number of repetitions N instead of taking the subsequent N timeslots as an effective resource, and then takes the N uplink timeslots as an available resource, and performs uplink transmission in the N uplink timeslots.

In an embodiment, the method of embodiment 1 may also be combined, the number of repetitions is updated by using a method such as a number coefficient, and then the terminal determines the uplink timeslot based on the updated number of repetitions. For example, according to embodiment 1, the updated repetition number is determined to be a × N, so that the terminal may determine a × N uplink timeslots in which uplink transmission is then performed.

In an embodiment, the base station may carry the number coefficient through a DFI (Downlink Feedback Information), and the sending the update indication of the number of repetitions to the terminal includes: and sending the DFI carrying the time coefficient to the terminal. Based on this, in an embodiment, the terminal may receive the DFI carrying the time coefficient, which is sent by the base station.

Thus, example 2 was completed. According to the method described in embodiment 2, the base station can update the number of repetitions of the terminal transmission uplink by updating the definition of the number of repetitions of the currently configured uplink. For example, for the currently configured repetition number N, the terminal does not perform transmission in the uplink time slot of the subsequent N time slots, but performs transmission in the subsequent N uplink time slots. Therefore, the base station can instruct and increase the transmission times of the terminal by the method of the embodiment, so that the times of the terminal repeated transmission reaches the configured repeated times, and the transmission reliability is improved.

In one embodiment, the base station may further separately feed back each piece of information in the terminal transmission through the DFI, so that the terminal may determine the repetition policy according to the DFI sent by the base station. This is explained below with reference to fig. 2 to 3.

Fig. 2 is a schematic flow chart diagram illustrating another uplink transmission method according to an embodiment of the present disclosure. As shown in fig. 2, the method further comprises:

in step S201, in response to the DFI with the reception failure flag sent by the base station, the uplink transmission is continuously repeated according to the currently configured repetition number.

In one embodiment, the base station may send the DFI to the terminal after the terminal completes the repeated transmission of N slots according to the currently configured number of repetitions N. For example, if the base station fails to receive the repeated information (for example, the repeated information is not received or the information is missing), the base station may carry a reception failure identifier in the DFI, and send the DFI to the terminal.

In one embodiment, the terminal may continue to transmit after receiving the DFI according to the number of repetitions of the current configuration. Alternatively, the terminal may continue to transmit according to the updated repetition number.

For example, if the currently configured number of repetitions N is 8, and after the terminal actually repeats 4 transmissions in 4 uplink timeslots in 8 timeslots, if receiving the DFI with reception failure sent by the base station, the terminal continues to repeat in the subsequent timeslots, for example, may continue to perform 4 transmissions.

In one embodiment, the base station may also instruct the terminal to stop transmission through DFI, which is described below with reference to fig. 3.

Fig. 3 is a schematic flow chart diagram illustrating a method of uplink transmission in accordance with an embodiment of the present disclosure. As shown in fig. 3, the method further comprises:

in step S301, in response to the DFI which is sent by the base station and does not carry the reception failure flag, stopping transmission;

or stopping transmission in response to the DFI carrying the receiving success identification sent by the base station.

In an embodiment, after the terminal completes the repeated transmission of N time slots according to the currently configured number of times of repetition N, if the base station successfully receives the repeated information, the base station may carry a reception success identifier in the DFI and issue the DFI to the terminal. In one embodiment, the terminal may stop transmission and may then begin transmitting new information upon determining that the base station has successfully received the information.

In an embodiment, the DFI sent by the base station may not carry an identifier, and the receiving is indicated to be successful in a default manner, so as to indicate the terminal to stop transmitting. It should be noted that the base station and the terminal determine the specific meaning of the DFI in advance, and when the terminal receives the DFI not carrying the reception failure flag, it may determine that the base station has successfully received, so that the terminal may stop transmission, and then may start to transmit new information.

To this end, the embodiment shown in fig. 2 and 3 is completed. According to the embodiments shown in fig. 2 and fig. 3, for each piece of transmitted information, the base station may instruct the terminal to continue repeating in case of a reception failure, thereby ensuring transmission reliability; under the condition of successful receiving, the base station timely indicates the terminal to stop transmission, thereby saving energy consumption and reducing information delay.

Fig. 4 is a schematic flow chart diagram illustrating a method of uplink transmission according to an embodiment of the present disclosure. The uplink transmission method shown in this embodiment may be applied to base stations including, but not limited to, 4G base stations, 5G base stations, and 6G base stations. The base station may communicate with a terminal as a user equipment, where the terminal includes, but is not limited to, a mobile phone, a tablet computer, a wearable device, a sensor, an internet of things device, and other electronic devices. In an embodiment, the terminal may be a terminal to which the uplink transmission method described in any of the above embodiments is applied.

As shown in fig. 4, the uplink transmission method may include the steps of:

in step S401, a repetition number update indication is sent to the terminal, for instructing the terminal to update the repetition number of the uplink transmission based on the repetition number update indication and the currently configured uplink repetition number.

In one embodiment, the base station may send a number of repetitions update indication to the terminal. The base station may send the update indication of the number of repetitions to the terminal in various manners, for example, the update indication may be carried in a system message, DCI (Downlink Control Information), and the like.

In one embodiment, after receiving the update indication of the number of repetitions sent by the base station, the terminal may update the number of repetitions of the uplink transmission based on the update indication of the number of repetitions and the currently configured number of repetitions of the uplink. Wherein, the uplink may include at least one of PUSCH and PUSCH, that is, updating the number of repetitions of the uplink includes: updating at least one of the PUSCH and the number of repetitions of the PUSCH.

According to the embodiment shown in fig. 4, the base station may flexibly instruct the terminal to update the number of times of repeated transmission on the uplink through the repetition number update indication, for example, the number of transmissions may be reduced in the case of good transmission, and the number of transmissions may be increased in the case of poor transmission. Therefore, the terminal can flexibly adjust the repetition times of the transmission uplink, and avoid resource waste on the basis of ensuring the transmission reliability.

In one embodiment, the indication of the number of repetitions update comprises a number of coefficients. In one embodiment, the terminal may use the product a × N of the number coefficient a and the currently configured number of repetitions N as the updated number of repetitions. Alternatively, the terminal may update the repetition number by another calculation method, for example, a product of a square of a number coefficient and the repetition number, and the embodiment is not limited thereto.

In one embodiment, the method for determining the above time coefficient by the base station also includes multiple methods, which are described below in conjunction with methods 1 to 3.

The method comprises the following steps: the base station may determine the number of times coefficient based on an uplink transmission quality of the terminal.

In one embodiment, the method further comprises: in response to the uplink transmission quality being higher than a first preset threshold, determining a number of times coefficient indicating that the terminal decreases the uplink repetition number; or, in response to the uplink quality being lower than a second preset threshold, determining that the number coefficient instructs the terminal to increase the uplink repetition number

The method 2 comprises the following steps: the base station may determine the number coefficient based on a reception result of the preset amount of information transmitted by the terminal.

In one embodiment, the method further comprises: in response to the reception success of the preset number of messages sent by the terminal, determining a number coefficient to instruct the terminal to reduce the uplink repetition number; or, in response to a preset number of information reception failures transmitted by the terminal, determining that the number of times coefficient instructs the terminal to increase the uplink repetition number.

Wherein the determining the number of times coefficient indicates the terminal to decrease the uplink repetition number comprises: for each piece of the preset amount of information, determining the number of terminal repetition times corresponding to the piece of information which is successfully received; and determining a frequency coefficient based on the repetition frequency respectively corresponding to each piece of information after successful receiving.

In one embodiment, the sending the update indication of the number of repetitions to the terminal includes: and sending the DFI carrying the time coefficient to the terminal.

In one embodiment, the number of times coefficient is a preset candidate coefficient or one of a plurality of preset candidate coefficients.

The method 3 comprises the following steps: the base station may determine the number of times coefficient based on a ratio of uplink time slots to downlink time slots in the uplink TDD time slot configuration.

For the above methods 1 to 3, reference may be made to terminal-side embodiments 1.1 to 1.3, which are not described herein again.

In an embodiment, the number coefficient may not be included in the update indication of the number of repetitions issued by the base station. For example, the repetition number update indication is used to instruct the terminal to determine one or more uplink timeslots based on the repetition number of the currently configured uplink.

The base station may update the terminal transmission uplink repetition number by updating the definition of the currently configured uplink repetition number. For example, for the currently configured repetition number N, the terminal does not perform transmission in the uplink time slot of the subsequent N time slots, but performs transmission in the subsequent N uplink time slots. Therefore, the base station can instruct to increase the transmission times of the terminal by the method of the embodiment, so that the repeated transmission times of the terminal reach the configured repeated times, and the transmission reliability is improved.

In an embodiment, the base station may further separately feed back each piece of Information in the terminal transmission through a DFI (Downlink Feedback Information), so that the terminal may determine the transmission policy according to the DFI sent by the base station. This is explained below with reference to fig. 5 to 6.

in step S501, in response to failure of receiving information transmitted by a terminal, transmitting a DFI to the terminal; wherein, the DFI carries a reception failure flag for instructing the terminal to continue repeating uplink transmission according to the repetition number of the current configuration.

Fig. 6 is a schematic flow chart diagram illustrating another uplink transmission method according to an embodiment of the present disclosure. As shown in fig. 8, the method further comprises:

in step S601, in response to the information transmitted by the receiving terminal being successful, transmitting a DFI to the terminal; wherein, the DFI does not carry a reception failure flag, and is used to instruct the terminal to stop transmission.

Or, in step S602, in response to the information transmitted by the receiving terminal being successful, transmitting a DFI to the terminal; wherein, the DFI carries a receiving success identifier for instructing the terminal to stop transmission.

According to the embodiments shown in fig. 5 and fig. 6, for each piece of transmitted information, the base station may instruct the terminal to continue repeating in case of a reception failure, thereby ensuring transmission reliability; under the condition of successful receiving, the base station timely indicates the terminal to stop transmission, thereby saving energy consumption and reducing information delay.

In one embodiment, the repetition number update indication indicates that the terminal updates at least one of the PUSCH and the PUSCH repetition number.

One specific paging announcement indication mechanism according to the present disclosure is illustrated generally below, with specific technical details, as follows:

in the related art, in R16, in order to improve reliability of URLLC uplink data, PUSCH repetition schemes are supported, and are divided into two schemes, namely, repetition type a and repetition type B, in the R17 coverage enhancement problem, PUSCH repetition may be performed in order to improve uplink coverage, and PUSCH signals repeated multiple times may be combined to obtain a higher signal-to-noise ratio.

Although the original PUSCH retransmission type a scheme may be nominally configured with 16 repetitions at most, for some TDD systems with more downlink timeslot configurations, such as (DL: UL ═ 7:3 or 4: 1), due to a large amount of unavailable resources, the PUSCH retransmission may be cancelled, resulting in the actual number of retransmissions being much less than the nominal number of retransmissions, thereby severely reducing the uplink coverage performance. For some cases with better coverage, too many repetitions are also a waste of resources.

The embodiment of the disclosure provides a repetition scheme of a PUSCH repetition type a, and the original standard specifies that once N nominal repetitions are configured, it is considered as an effective available resource within the duration of subsequent N slots and N × L symbols, and the UE sends a PUSCH on the effective uplink resource respectively. When the coverage condition is better, the transmission of the PUSCH type A can be ended in advance according to the receiving quality of the SNR, and the waste of resources is avoided. When the coverage is particularly poor, if the available resources are used up, but the reception quality is not satisfied, the number of times of PUSCH actual repetition needs to be ensured, the PUSCH actual repetition is continuously transmitted, and the reception quality is ensured.

In the disclosed embodiment, the maximum nominal number of repetitions N may be reduced/expanded

It should be noted that, if the modification is directly from 16 to 32, one is that the corresponding TDRA table also needs to be modified, which affects the overhead of the TDRA table and affects the DCI indicating bit number, and furthermore, the value of 32 may be too large or too small, and is not suitable for all situations.

In one embodiment, an expansion or reduction factor β may be defined that only expands or reduces N for the number of repetitions, e.g., N' ═ N × β.

In one embodiment, the method for determining the beta value may include

1. Defining candidate value β {0.5,1,2,4,8}, determining β in advance according to the CE target, e.g. for a required boost of 5dB, RRC advance configuration β ═ 2.

2. Defining a candidate value β ═ {0.5,1,2,4,8}, introducing a DFI, determined from ACK/NACK, DCI indication

3. The specific value is not defined, and the specific value is calculated in advance according to the TDD system DL: UL time slot configuration.

In one embodiment, the definition of N and the corresponding resource scope may be modified. The definition of N in the original protocol represents the subsequent continuous N slots, the definition of N is modified into N subsequent uplink slots, and the corresponding counting rule is modified accordingly.

In one embodiment, the continuation may be based on a default number of retransmissions.

For example, if 8 are configured, 4 are actually transmitted. And the base station demodulates and issues the DFI, and if the DFI indicates NACK, the terminal transmits the NACK for 4 times. Otherwise, the transmission is terminated and the new data TBS is started to be sent.
