Description

Technical Field

[0001] The invention relates to wireless communication technology, and in particular to a hybrid automatic repeat request (HARQ) number determination method, network equipment, terminal and computer storage medium. Background Art

[0002] The current 5G system has introduced Ultra-Reliable Low Latency Communication (URLLC), which is characterized by ultra-high reliability (for example, 99.999%) transmission within extreme latency (for example, 1ms). In order to achieve this goal, the concept of Grant free was proposed. Grant free adopts a pre-configured\semi-continuous state resource configuration method, and the terminal can transmit on the configured resources according to business needs. This technology avoids the process of resource request (SR, Schedule Request) and buffer status report (BSR, Buffer Status Report), and increases the effective transmission time of the terminal.

[0003] HARQ is generally implemented in a "stop-and-wait" manner. For a certain HARQ process, before waiting for ACK / NACK feedback, this process temporarily stops transmission. After receiving feedback / scheduling signaling, it chooses to send new data or retransmit old data based on the feedback result / scheduling information. In order to ensure system transmission efficiency, HARQ uses multiple processes. That is, while a process is waiting for feedback / scheduling, other processes are transmitted. In order to avoid data confusion between multiple processes, HARQ numbers (IDs) are used to represent HARQ processes.

[0004] The HARQ ID in the Long Term Evolution (LTE) system is calculated based on the Transmission Time Interval (TTI), period, and number of processes. However, in the 5G system, if repeated transmission is used under the Grant Free mechanism, the HARQ indication will be inaccurate. For example, different HARQ IDs are obtained by repeated calculations of the same data block (TB). In this way, one TB corresponds to multiple processes, which not only reduces the efficiency of retransmission merging, but also causes the problem of incorrect merging of different TBs. Summary of the invention

[0110] HARQ Process ID=[floor(t_temp-Toffset_temp / T_temp)]modulo B (1)

[0111] Among them, HARQ Process ID is the HARQ number, t represents the time domain resource sequence number of the current transmission, Toffset represents the time domain resource offset, T represents the time domain resource period, and B represents the number of HARQ processes; floor represents rounding down, and of course, it can also be processed by rounding up in other ways; modulo represents modulo operation. t_temp, Toffset_temp, and T_temp are parameters obtained by converting t, Toffset, and T according to specific time units, respectively. The absolute time units of t_temp, Toffset_temp, and T_temp are the same, and the absolute time units of t, Toffset, and T can be the same or different.

[0112] Figure 3a and Figure 3b FIG. 1 is a schematic diagram of a first application of the HARQ number determination method according to an embodiment of the present invention; Figure 3a As shown, the units of Toffset and T are the same as the absolute duration of transmission, for example: T = 2ms (2 slots), Toffset = 1ms (1 slot), the number of processes is 3, and the absolute duration of one transmission is 1ms (1 slot), then Toffset_temp = Toffset, T_temp = T, then the HARQ ID calculated according to expression (1) satisfies:

[0113] HARQ Process ID=[floor(t-1 / 2)]modulo 3;

[0114] Then when t=1, 2, HARQ Process ID=0; when t=3, 4, HARQ Process ID=1; when t=5, 6, HARQ Process ID=2.

[0115] The starting number of the HARQ process in the above scenario is 0. If the starting number of the HARQ process is not 0, an offset value is added to the above expression (1). For example, if the starting number of the HARQ process is 1, the HARQ ID satisfies:

[0116] HARQ Process ID=[floor(t_temp-Toffset_temp / T_temp)]modulo B+1.

[0117] like Figure 3bAs shown, the units of Toffset and T are different from the absolute duration of transmission. For example, T=2ms (2slots), Toffset=1ms (1slot), the number of processes is 3, and the absolute duration of one transmission is 0.5ms (0.5slot). Then, Toffset_temp=1 / 0.5=2, T_temp=2 / 0.5=4. Then, the HARQ ID calculated according to expression (1) satisfies:

[0118] HARQ Process ID=[floor(t-2 / 4)]modulo 3;

[0119] Then when t=2, 4, HARQ Process ID=0; when t=6, 8, HARQ Process ID=1; when t=10, 12, HARQ Process ID=2.

[0120] The starting number of the HARQ process in the above scenario is 0. If the starting number of the HARQ process is not 0, an offset value is added to the above expression (1). For example, if the starting number of the HARQ process is 1, the HARQ ID satisfies:

[0121] HARQ Process ID=[floor(t_temp-Toffset_temp / T_temp)]modulo B+1.

[0122] In the embodiment of the present invention, T represents the interval between two non-automatic retransmission transmissions.

[0123] Scene 2

[0124] This scenario determines the HARQ number based on the time domain resource sequence number, time domain resource offset, time domain resource period, number of HARQ processes and HARQ number offset of the current transmission. The technical solution of this scenario is used to solve the problem of HARQ ID overlap in the scenario of multiple Grant free resource configurations. As an example, the HARQ number satisfies the following expression:

[0125] HARQ Process ID=[floor(t_temp-Toffset_temp / T_temp)]modulo B+Hoffset(2)

[0126] Among them, HARQ Process ID is the HARQ number, t represents the time domain resource sequence number of the current transmission, Toffset represents the time domain resource offset, T represents the time domain resource period, B represents the number of HARQ processes; Hoffset represents the HARQ ID offset; floor represents rounding down, of course, in other methods, it can also be processed by rounding up operation; modulo represents modulo operation. t_temp, Toffset_temp, T_temp are parameters obtained by converting t, Toffset, and T according to specific time units, respectively. The absolute time units of t_temp, Toffset_temp, and T_temp are the same, and the absolute time units of t, Toffset, and T can be the same or different.

[0127] Figure 4a and Figure 4b FIG. 2 is a schematic diagram of a second application of the HARQ number determination method according to an embodiment of the present invention; Figure 4a and Figure 4b As shown, for the scenario where the units of Toffset and T are the same as the absolute duration of transmission, two Grant free resources are configured. Grant Free Resource 1: T1 = 2ms (2slots), Toffset1 = 1ms (1slot), the number of processes is 3, and Hoffset = 0; Grant Free Resource 2: T2 = 4ms (4slots), Toffset2 = 1ms (1slot), the number of processes is 2, and Hoffset = 3; the absolute duration of a transmission is 1ms (1slot), then the HARQ IDs calculated by Grant Free Resource 1 and Grant Free Resource 2 according to expression (2) satisfy:

[0128] HARQ Process ID for Grant free 1=[floor(t-1 / 2)]modulo 3;

[0129] HARQ Process ID for Grant free 2=[floor(t-1 / 4)]modulo 2+3;

[0130] Then for Grant free resource 1, if Figure 4a As shown, when t=1, 2, HARQ Process ID=0; when t=3, 4, HARQ Process ID=1; when t=5, 6, HARQ Process ID=2.

[0131] Then for Grant free resource 2, if Figure 4bAs shown, when t=1, 2, HARQ Process ID=3; when t=5, 6, HARQ Process ID=4.

[0132] The starting number of the HARQ process in the above scenario is 0. If the starting number of the HARQ process is not 0, an offset value is added to the above expression (2). For example, if the starting number of the HARQ process is 1, the HARQ ID satisfies:

[0133] HARQ Process ID=[floor(t_temp-Toffset_temp / T_temp)]moduloB+Hoffset+1.

[0134] The above example is a scenario where the units of Toffset and T are the same as the absolute duration of the transmission. For scenarios where the units of Toffset and T are different from the absolute duration of the transmission, refer to scenario 1. Figure 3b The calculation description of Toffset and T is not given in this scenario.

[0135] In the embodiment of the present invention, T represents the interval between two non-automatic retransmission transmissions.

[0136] Scene 3

[0137] In this scenario, the HARQ number is determined based on the time domain resource sequence number, time domain resource period, number of HARQ processes and HARQ number offset of the current transmission. As an example, the HARQ number satisfies the following expression:

[0138] HARQ Process ID=[floor(t_temp / T_temp)]modulo B+Hoffset (3)

[0139] Among them, HARQ Process ID is the HARQ number, t represents the time domain resource sequence number of the current transmission, T represents the time domain resource period, B represents the number of HARQ processes; Hoffset represents the HARQ ID offset; floor represents rounding down, of course, it can also be processed by rounding up in other ways; modulo represents modulo operation. t_temp and T_temp are parameters obtained by converting t and T according to specific time units, respectively. The absolute time units of t_temp and T_temp are the same, and the absolute time units of t and T can be the same or different. Usually, the starting position of this scenario is restricted. For example, the starting position of the Grant free resource must be an integer multiple of the period, or the starting position modulo period is less than the period; or the sum of the starting position and the number of repetitions modulo period is less than the period.

[0140] Figure 5a and Figure 5b FIG. 4 is a schematic diagram of a third application of the HARQ number determination method according to an embodiment of the present invention; Figure 5a and Figure 5b As shown, for the scenario where the units of Toffset and T are the same as the absolute duration of transmission, two Grant free resources are configured. Grant Free Resource 1: T1 = 2ms (2slots), the number of processes is 3, Hoffset = 0; Grant Free Resource 2: T2 = 4ms (4slots), the number of processes is 2, Hoffset = 3; the absolute duration of a transmission is 1ms (1slot), then the HARQ IDs calculated by Grant Free Resource 1 and Grant Free Resource 2 respectively according to expression (3) satisfy:

[0141] HARQ Process ID for grant free1=[floor(t / 2)]modulo 3;

[0142] HARQ Process ID for grant free2=[floor(t / 4)]modulo 2+3;

[0143] Then for Grant free resource 1, if Figure 5a As shown, when t=1, 2, HARQ Process ID=0, when t=3, 4, HARQ Process ID=1; when t=5, 6, HARQ Process ID=2.

[0144] Then for Grant free resource 2, if Figure 5b As shown, when t=1, 2, HARQ Process ID=3, and when t=5, 6, HARQ Process ID=4.

[0145] The starting number of the HARQ process in the above scenario is 0. If the starting number of the HARQ process is not 0, an offset value is added to the above expression (3). For example, if the starting number of the HARQ process is 1, the HARQ ID satisfies:

[0146] HARQ Process ID=[floor(t_temp / T_temp)]modulo B+Hoffset+1.

[0147] The above example is a scenario where the units of Toffset and T are the same as the absolute duration of the transmission. For scenarios where the units of Toffset and T are different from the absolute duration of the transmission, refer to scenario 1. Figure 3b The calculation description of Toffset and T is not given in this scenario.

[0148] Scene 4

[0149] This scenario determines the HARQ number based on the time domain resource sequence number of the current transmission, the time domain resource offset, the number of transmissions of the current transmission data block, the time domain resource period, the number of HARQ processes and the HARQ number offset. The technical solution of this scenario avoids the situation where the same data block corresponds to multiple HARQ IDs due to multiple repeated transmissions, especially in the scenario where the number of repeated transmissions is greater than the Grant free resource time domain period T. As an example, the HARQ number satisfies the following expression:

[0150] HARQ Process ID=[floor(t_temp-Toffset_temp-current_n / T)]modulo B+Hoffset (4)

[0151] Among them, HARQ Process ID is the HARQ number, t represents the time domain resource sequence number of the current transmission, Toffset represents the time domain resource offset, current_n represents the number of transmissions of the current transmission data block, T represents the time domain resource cycle, B represents the number of HARQ processes; Hoffset represents the HARQ ID offset; floor represents rounding down, of course, in other methods, it can also be processed by rounding up operation; modulo represents modulo operation. t_temp, Toffset_temp, T_temp are parameters obtained by converting t, Toffset, and T according to specific time units, respectively. The absolute time units of t_temp, Toffset_temp, and T_temp are the same, and the absolute time units of t, Toffset, and T can be the same or different. Among them, if the number of transmissions starts from 0, current_n is directly expressed in the formula; if the number of transmissions starts from 1, current_n-1 is directly expressed in the formula. Among them, T (including T1 and T2) is the time domain interval of Grant free resources.

[0152] For details on the application of this scenario, please refer to Figure 4a and Figure 4bAs shown, for the scenario where the units of Toffset and T are the same as the absolute duration of transmission, two Grant free resources are configured. Grant Free Resource 1: T1 = 1ms (2slots), Toffset1 = 1ms (1slot), the number of processes is 3, and Hoffset = 0; Grant Free Resource 2: T2 = 4ms (4slots), Toffset2 = 1ms (1slot), the number of processes is 2, and Hoffset = 3; the absolute duration of a transmission is 1ms (1slot), then the HARQ IDs calculated by Grant Free Resource 1 and Grant Free Resource 2 respectively according to expression (4) satisfy:

[0153] HARQ Process ID for Grant free 1=[floor(t-1-current_n / 2)]modulo 3;

[0154] HARQ Process ID for Grant free 2=[floor(t-1-currrent_n / 4)]modulo 2+3;

[0155] Then for Grant free resource 1, if Figure 4a As shown, when t=1, 2, current_n=0, 1, HARQ Process ID=0; when t=3, 4, current_n=0, 1, HARQ Process ID=1; when t=5, 6, HARQ Process ID=2.

[0156] Then for Grant free resource 2, if Figure 4b As shown, when t=1, 2, current_n=0, 1, HARQ Process ID=3; when t=5, 6, current_n=0, 1, HARQ Process ID=4.

[0157] The starting number of the HARQ process in the above scenario is 0. If the starting number of the HARQ process is not 0, an offset value is added based on the above expression (4). For example, if the starting number of the HARQ process is 1, the HARQ ID satisfies:

[0158] HARQ Process ID=[floor(t_temp-Toffset_temp-current_n / T)]modulo B+Hoffset+1.

[0159] As another example, Figure 6a and Figure 6b FIG. 4 is a schematic diagram of a fourth application of the HARQ number determination method according to an embodiment of the present invention; Figure 6a and Figure 6b As shown, for the scenario where the units of Toffset and T are the same as the absolute duration of transmission, two Grant free resources are configured. Grant Free Resource 1: T1 = 1ms (2slots), Toffset1 = 1ms (1slot), the number of processes is 3, and Hoffset = 0; Grant Free Resource 2: T2 = 4ms (4slots), Toffset2 = 1ms (1slot), the number of processes is 2, and Hoffset = 3; the absolute duration of a transmission is 1ms (1slot), then the HARQ IDs calculated by Grant Free Resource 1 and Grant Free Resource 2 respectively according to expression (4) satisfy:

[0160] HARQ Process ID for Grant free 1=[floor(t-0-current_n / 2)]modulo 3;

[0161] HARQ Process ID for Grant free 2=[floor(t-1-currrent_n / 4)]modulo 2+3;

[0162] Then for Grant free resource 1, if Figure 6a As shown, when t=1, 2, current_n=0, 1, HARQ Process ID=0; when t=3, 4, current_n=0, 1, HARQ Process ID=1; when t=5, 6, HARQ Process ID=2.

[0163] Then for Grant free resource 2, if Figure 6b As shown, when t=1, 2, current_n=0, 1, HARQ Process ID=3; when t=5, 6, current_n=0, 1, HARQ Process ID=4.

[0164] The above example is a scenario where the units of Toffset and T are the same as the absolute duration of the transmission. For scenarios where the units of Toffset and T are different from the absolute duration of the transmission, refer to scenario 1. Figure 3b The calculation description of Toffset and T is not given in this scenario.

The absolute time units of t_temp, Toffset_temp, and T_temp are the same, and the absolute time units of t, Toffset, and T can be the same or different. Wherein, if the number of transmissions starts from 0, current_n is directly used in the formula to express it; if the number of transmissions starts from 1, current_n-1 is directly used in the formula to express it. Wherein, T (including T1 and T2) is the time domain interval of Grant free resources.

As an example, the HARQ number satisfies the following expression:

[0175] HARQ Process ID=[floor(t_temp-current_n / T)]modulo B.

Among them, T (including T1 and T2) is the time domain interval of Grant free resources.

[0177] Scene 8

[0178] Based on the aforementioned scenarios 4 to 7, when determining the HARQ number in combination with the number of transmissions of the current transmission data block, a transmission pattern may be further included. It can be understood that, as a first implementation, the network device determines the HARQ number based on the time domain resource sequence number of the current transmission, the number of transmissions of the current transmission data block, the time domain resource period, the number of HARQ processes and the HARQ number offset, including: the network device determines the HARQ number based on the time domain resource sequence number of the current transmission, the number of transmissions of the current transmission data block, the transmission pattern of the current transmission, the time domain resource period, the number of HARQ processes and the HARQ number offset.
