Hereinafter, technical solutions according to embodiments of the present disclosure will be clearly and completely described with reference to drawings in embodiments of the present disclosure. It is obvious that the described embodiments are only some embodiments of the present disclosure, but not all embodiments. Based on the embodiments of the present disclosure, all other embodiments obtained under the premise that those skilled in the art do not do creative work fall within the protection scope of the present disclosure.

As used herein, the term 'comprising' or any other variation thereof, encompasses a non-exclusive inclusion, e.g., a process, method, system, article or device comprising a series of steps or units, including those steps explicitly recited. and units, but is intended to further include other steps or units not explicitly listed or unique to such process, method, article or device. In addition, “and/or” in this specification indicates at least one of the connection objects, and for example, “A and/or B” includes three cases where individual A, individual B , and A and B coexist.

In the presently disclosed embodiments, terms such as “for example” or “for example” indicate an example or description. It should not be understood that any embodiment or implementation described as "for example" or "for example" in the present disclosure is preferred or has more advantages than other embodiments or implementations. Specifically, the use of terms such as “for example” or “for example” is intended to explain related concepts in a specific manner.

Referring to FIG. 1 and Table 1, in the NR URLLC scheme, a base station (gNB) configures transmission of a PUSCH using signaling first, and a resource distribution period P, a redundancy number K, and a redundancy version (RV) sequence , includes information such as locations of K resources of the number of repetitions in the period P, and the location of the resources of the number of repetitions K becomes a transmission opportunity (Transmission Opportunity, TO) of K repetitions.

Here, Table 1 is a URLLC uplink non-scheduling scheme, configuring different overlapping times K, and corresponding transmission schemes for different RV configurations.

RV = {0 0 0 0} RV = {0 3 0 3} RV = {0 2 3 1} K=1 {0} {0} {0} K=2 {0 0} if start from ^1st TO {0 3} always start from 1 ^st TO {0 2} always start from ^1st TO {0} if start from ^2nd TO K=4 {0 0 0 0} if start from ^1st TO {0 3 0 3} if start from ^1st TO {0 2 3 1} always start from ^1st TO {0 0 0} if start from ^2nd TO {0 0} if start from ^3rd TO {0 3} if start from ^3rd TO {0} if start from ^4th TO K=8 {0 0 0 0 0 0 0 0} if start from ^1st TO {0 3 0 3 0 3 0 3} if start from ^1st TO {0 2 3 1 0 2 3 1} always start from ^1st TO {0 0 0 0 0 0 0} if start from ^2nd TO {0 0 0 0 0 0} if start from ^3rd TO {0 3 0 3 0 3} if start from ^3rd TO {0 0 0 0 0} if start from ^4th TO {0 0 0 0} if start from ^5th TO {0 3 0 3} if start from ^5th TO {0 0 0} if start from ^6th TO {0 0} if start from ^7th TO {0 3} if start from ^7th TO

Table 1 It is configured through Radio Resource Control (RRC) according to the current standard. For example, if P=4, K=4, RV={0 0 0 0}, the time domain resource location is {start orthogonal frequency is an Orthogonal Frequency Division Multiplexing (OFDM) symbol, the number of OFDM symbols, and this time-domain location is defined as one transmission opportunity (TO), that is, completes one redundant transmission, K = 4 is four redundant This means that the transmission must proceed, and four TOs are required. When the data arrives before the first TO, the first TO can be used to transmit, then 4 times can be transmitted, RV is {0 0 0 0}; When the data arrives after the first TO but before the second TO, the transmission can proceed using the second TO, then it can transmit 3 times, RV is {0 0 0}; When the data arrives after the second TO and before the third TO, the transmission can proceed using the third TO, then transmission can be performed twice, RV is {0 0}; When data arrives after the third TO and before the fourth TO, transmission can be performed using the fourth TO, in which case number 1 can be transmitted, and RV is {0}. Each corresponds to case 1, case 2, case 3, and case 4 in FIG. 1 .

It is configured through RRC according to the current standard. For example, if P=4, K=4, and RV={0 3 0 3}, the time domain resource location is {start OFDM symbol, number of OFDM symbols}, and this time domain location is defined as one transmission opportunity (TO), that is, one redundant transmission is completed, K = 4 means that 4 redundant transmissions must be performed, and 4 TOs are required. When the data arrives before the first TO, the first TO can be used to transmit, then 4 can be transmitted, RV is {0 3 0 3}; When the data arrives after the first TO but before the third TO, the transmission can proceed using the third TO, then transmission can be performed twice, RV is {0 3}; When data arrives after the third TO, transmission is not performed within this cycle, and transmission is postponed to the next cycle. Corresponds to cases 5 and 6 in FIG. 1 , respectively.

It is configured through RRC according to the current standard. For example, if P=4, K=4, and RV={0 2 3 1}, the time domain resource location is {start OFDM symbol, number of OFDM symbols}, and this time domain location is defined as one transmission opportunity (TO), that is, one redundant transmission is completed, K = 4 means that 4 redundant transmissions must be performed, and 4 TOs are required. When the data arrives before the first TO, the first TO can be used to transmit, then 4 times can be transmitted, RV is {0 2 3 1}; When data arrives after the first TO, transmission is not performed within this period, and transmission is postponed to the next period. Each corresponds to case 7 in FIG. 1 .

In the current scheme of NR URLLC, latency performance can be guaranteed only when RV={0 0 0 0}, that is, satisfies that the terminal can transmit PUSCH in each TTI; RV={0 3 0 3} cannot guarantee latency performance. For example, if data arrives after TO 0 but before TO 1, the UE cannot start PUSCH transmission from TO 1 and must transmit PUSCH from TO 2 according to the standard definition. should be sent RV = {0 2 3 1} cannot guarantee latency performance, and for example, if data arrives after TO 0, the UE has no choice but to start PUSCH transmission in the next cycle.

In the current scheme of NR URLLC, RV={0 0 0 0} and RV={0 3 0 3} cannot achieve the configured number of overlapping transmissions, so reliability cannot be guaranteed; Since RV={0 2 3 1} can achieve the configured number of overlapping transmissions, reliability can be guaranteed.

Therefore, in the current scheme of NR URLLC, it is not possible to implement a smooth balance between high reliability and high complexity under the premise of guaranteeing low latency demand.

In some embodiments of the present disclosure, if K number of duplicate transmissions have not been reached, it is indicated that there are more transmission opportunities within the period, and duplicate transmissions are performed on the corresponding transmission opportunities.

Step 505: The terminal judges whether the overlapping transmission crosses the boundary of the period, and if it crosses, executes step 507, otherwise executes step 506.

In some embodiments of the present disclosure, redundant transmission is performed according to an RV value in an RV sequence, and when performing subsequent redundant transmissions, it is determined whether K duplicated transmissions have been reached.

Step 507: The terminal judges whether the network permits the terminal to transmit across periods, and if permitted, executes step 508;

In some embodiments of the present disclosure, when redundant transmission crosses the boundary of a period and the network device does not allow the terminal to transmit across the period, the redundant transmission is terminated.

Step 508: The terminal determines whether the RV value of the current redundant transmission in the RV sequence is 0, and if it is 0, the RV value is another value (eg, 1, 2, or 3) and proceeds with redundant transmission, again in step 506. Execute, and if not 0, execute step 506 again.

In some embodiments of the present disclosure, when redundant transmission crosses the boundary of a period, the network device allows the terminal to transmit across the period, and the RV value is not 0, redundant transmission according to the RV value in the RV sequence. and it is determined whether the boundary of the period is crossed when performing the next redundant transmission.
