Obviously, the described embodiments are some of the embodiments of the present invention, but not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making progressive efforts belong to the protection scope of the present invention.

The term "comprising" and any variations thereof in the specification and claims of the present invention are intended to cover a non-exclusive inclusion, for example, a process, method, system, product or device comprising a series of steps or units is not necessarily limited to the express instead of those steps or elements explicitly listed, other steps or elements not explicitly listed or inherent to the process, method, product or apparatus may be included. In addition, the use of "and/or" in the specification and scope of claims indicates at least one of the connected objects, such as A and/or B, which means that there are three situations including A alone, B alone, and both A and B.

In the embodiments of the present invention, words such as "exemplary" or "for example" are used as examples, illustrations or descriptions. Any embodiment or design scheme described as "exemplary" or "for example" in the embodiments of the present invention should not be interpreted as being more preferred or more advantageous than other embodiments or design schemes. Rather, the use of words such as "exemplary" or "such as" is intended to present related concepts in a concrete manner.

Referring to Figure 1 and Table 1, in the NR URLLC scheme, the base station (gNB) first uses signaling to configure the transmission of PUSCH, including the cycle P of resource configuration, the number of repetitions K, the redundancy version (Redundancy Version, RV) sequence, In the period P, information such as the location of resources is repeated for K times, and the resource positions for K times of repetitions become transmission opportunities (Transmission Opportunities, TOs) for K times of repetitions.

Wherein, Table 1 is the transmission scheme corresponding to different RV configurations with different repetition times K configured in the URLLC uplink scheduling-free transmission scheme.

According to the current standard, through radio resource control (Radio Resource Control, RRC) configuration, such as P=4, K=4, RV={0 0 0 0}, the time domain resource position is {starting OFDM (Orthogonal Frequency Division Multiplexing, OFDM) symbol, the number of OFDM symbols}, this time domain resource location is defined as a transmission opportunity TO, that is, to complete a repeated transmission, K=4 means to perform four repeated transmissions, four TOs are required . When the data arrives before the first TO, the first TO can be used for transmission, which will be transmitted four times, and the RV is {0 0 0 0}; when the data arrives after the first TO but before the second TO When the data arrives after the second TO but before the third TO, the third TO can be used for transmission. In this way, it will be transmitted twice, and the RV is {0 0}; when the data arrives after the third TO but before the fourth TO, the fourth TO can be used for transmission, which will be transmitted once, and the RV is {0}. Corresponding to example (case) 1, case 2, case 3, and case 4 in Figure 1 respectively.

According to the current standard, through RRC configuration, such as P=4, K=4, RV={0 3 0 3}, the time domain resource position is {starting OFDM symbol, number of OFDM symbols}, the time domain resource position definition For one transmission opportunity TO, that is, to complete one repeated transmission, K=4 means that four repeated transmissions are required, and four TOs are required. When the data arrives before the first TO, the first TO can be used for transmission, which will be transmitted four times, and the RV is {0 3 0 3}; when the data arrives after the first TO but before the third TO , you can use the third TO for transmission, which will be transmitted twice, and the RV is {0 3}; when the data arrives after the third TO, no transmission will be performed in this period, and it will be postponed to the next period to transfer. They correspond to case 5 and case 6 in Figure 1, respectively.

According to the current standard, through RRC configuration, such as P=4, K=4, RV={0 2 3 1}, the time domain resource position is {starting OFDM symbol, number of OFDM symbols}, the time domain resource position definition For one transmission opportunity TO, that is, to complete one repeated transmission, K=4 means that four repeated transmissions are required, and four TOs are required. When the data arrives before the first TO, the first TO can be used for transmission, which will be transmitted four times, and the RV is {0 2 3 1}; when the data arrives after the first TO, within this period If no transmission is performed, the transmission will be postponed until the next cycle. Corresponding to case 7 in Figure 1.

In the current NR URLLC solution, only RV={0 0 0 0} can guarantee the delay performance, that is, the terminal is allowed to send PUSCH in every TTI; RV={0 3 0 3} cannot guarantee the delay performance, For example, if data arrives after TO 0 and before TO 1, the terminal cannot start transmitting PUSCH from TO 1, but must start transmitting PUSCH from TO 2 according to the standard definition. RV={0 2 3 1} cannot guarantee the delay performance. For example, the data arrives after TO 0, and the terminal can only transmit PUSCH from the next cycle.

In the current NR URLLC scheme, RV={0 0 0 0} and RV={0 3 0 3} cannot guarantee reliability because the configured number of repeated transmissions cannot be reached; RV={0 2 3 1} can guarantee reliability Reliability, because the configured number of retransmissions can be reached.

Therefore, in the current NR URLLC solution, it is impossible to achieve a flexible compromise between high reliability and low complexity under the premise of ensuring low latency requirements.

Step 506: The terminal performs repeated transmission, and then re-executes step 504; in some embodiments of the present invention, performs repeated transmission according to the RV value in the RV sequence, and then continues to judge whether K repeated transmissions are reached during subsequent repeated transmissions.

Step 507: The terminal judges whether the network device allows the terminal to transmit across periods. If yes, execute step 508; otherwise, end the repeated transmission; When the terminal transmits across periods, the repeated transmission ends.

Step 508: The terminal judges whether the RV value of the current repeated transmission in the RV sequence is 0, if so, repeats the transmission according to the RV value being equal to other values (such as 1, 2 or 3), and then re-executes step 506, otherwise, re-executes step 506; In some embodiments of the present invention, when the repeated transmission crosses the boundary of the period, and the network device allows the terminal to transmit across the period, and the RV value is not 0, repeat the transmission according to the RV value in the RV sequence, and then When performing the next repeated transmission, judge whether it will cross the boundary of the period; when the repeated transmission crosses the boundary of the period, and the network device allows the terminal to transmit across the period, and the RV value is 0, follow RV=1, 2 or 3. Repeat the transmission, and then determine whether the boundary of the period will be crossed when performing the next repeated transmission.
