Description

Technical Field

[0001] This invention relates to the field of communication technology, and in particular to a method, apparatus, terminal, and network-side equipment for determining transmission resources. Background Technology

[0002] To promote the development of the Industrial Internet of Things (IIoT), Time Sensitive Networks (TSN) have emerged, aiming to establish a universal time-sensitive mechanism for the Ethernet protocol to ensure the time determinism of network data transmission.

[0003] When TSN services traverse 5G mobile communication networks, 5G networks typically employ a Configured Grant (CG) resource allocation method to carry TSN network resources. In existing technologies, the range of CG period values ​​is related to the subcarrier space configuration. For example, when the subcarrier space (SCS) is 15kHz, the CG period ranges from slots {1,2,4,5,8,10,16,20,32,40,64,80,128,160,320,640}. In existing technologies, the CG period has a few discrete values, making it difficult to perfectly match the period of TSN services.

[0004] Existing technologies provide the following methods for configuring CG resources:

[0005] Method 1: The CG resource period is slightly shorter than the TSN service period. For example, if the TSN service period is 70 time slots, select the closest number slightly shorter than 70 time slots from the CG period set {1,2,4,5,8,10,16,20,32,40,64,80,128,160,320,640}, i.e., 64 time slots, as the CG resource period for carrying TSN services. For example, TSN services generated in time slots 70, 140, 210, and 280 are delayed by time slots 128 (delayed by 58 time slots), 192 (delayed by 52 time slots), 256 (delayed by 46 time slots), and 320 (delayed by 40 time slots), respectively, resulting in significant delays and making it difficult to transmit data packets generated by the TSN network in a timely manner.

[0006] Method 2: The CG resource period is slightly longer than the TSN service period. For example, if the TSN service period is 70 time slots, select the closest number slightly longer than 70 time slots from the CG period set {1,2,4,5,8,10,16,20,32,40,64,80,128,160,320,640}, i.e., time slot 80, as the CG resource period for carrying the TSN service. Figure 1As shown, the TSN services generated in time slots 210, 280, and 350 are delayed by time slots 240 (delayed by 30 time slots), 320 (delayed by 40 time slots), and 400 (delayed by 50 time slots), respectively. The delay is still relatively large, and the data packets generated by the TSN network are difficult to be transmitted in a timely manner.

[0007] Given that TSN services are highly sensitive to latency, TSN data packets become invalid when the latency of the resources they carry exceeds a certain threshold (e.g., 10 time slots). Therefore, neither the CG resource determination methods in Method 1 nor Method 2 can meet the requirements of TSN services.

[0008] To meet the high latency sensitivity requirements of TSN networks, assuming the TSN service cycle is T_traffic and the effective latency threshold for data packets is Th1 (i.e., assuming a TSN data packet is generated at time t1, the data packet needs to be carried and transmitted within the time interval [t1, t1+Th1), otherwise the data packet is invalid or can be abandoned for transmission), a simple method to meet the above requirements is to configure the CG resource cycle T_resource <= Th1, ensuring that each data packet generated by TSN has timely CG carrying resources.

[0009] For example, if Th1 = 9 time slots, then T can be taken from time slots {1, 2, 4, 5, 8}. When T = 8 time slots, the TSN services generated in time slots 0, 70, 140, 210, and 280 are respectively delayed by time slot 0 (delay 0 time slot), time slot 72 (delay 2 time slots), time slot 144 (delay 4 time slots), time slot 216 (delay 6 time slots), and time slot 280 (delay 0 time slots). The delays are relatively small, and the delays are all controlled within Th1 (9 time slots), so the data packets generated by the TSN network can be transmitted in a timely manner.

[0010] Specifically, if T_resource is divisible by T_traffic, then ideally, a delay of 0 time slots can be guaranteed. For example, when T_resource = 10 time slots (note that T_resource = 10 time slots is divisible by T_traffic = 70 time slots), each TSN packet can be delivered in a timely manner (ideally, with a delay of 0 time slots when the starting offset of T_resource is configured properly).

[0011] Regardless of the configuration method used, the overhead of CG resources is significant, with many CG resources being wasted as they do not carry any TSN services. For example, when T_resource = 10 slots are selected, only 1 out of every 7 allocated CG resources is used to carry TSN packets, meaning that as much as 6 / 7 ≈ 86% of the CG resources are wasted.

[0012] In summary, when the period value in the time information of TSN services does not match the period value in the existing network, how to effectively determine 3GPP resources in order to effectively reduce the overhead of 3GPP bearer resources while meeting the timeliness requirements of TSN service bearing is an urgent problem to be solved. Summary of the Invention

[0013] The purpose of this invention is to provide a method, apparatus, terminal, and network-side device for determining transmission resources, so as to solve the problem that the resource determination method in the prior art cannot use the period value in the time information of TSN service and the period value in the existing 5G network.

[0262] To make the technical problems, technical solutions and advantages of the present invention clearer, a detailed description will be given below in conjunction with the accompanying drawings and specific embodiments.

[0263] like Figure 1 As shown, this embodiment of the invention also provides a method for determining transmission resources, applied to a terminal, including:

[0264] Step 11, determine a first set of transmission resources; the first set of transmission resources includes at least one transmission resource;

[0265] Step 12: Based on the arrival time of the data packet, determine the first transmission resource in the first transmission resource set to carry the data packet.

[0266] When a data packet arrives, a candidate transmission resource that meets the constraints is selected from the first set of transmission resources to carry the data packet. In one embodiment, the first transmission resource is also referred to as a "candidate" transmission resource. The first set of transmission resources is sometimes also referred to as a "candidate" transmission resource pool.

[0267] As an optional embodiment, the data packet is a data packet of a first service type. Optionally, the first service type is latency-sensitive; for example, the first service type is a latency-sensitive network (TSN) generated by the Industrial Internet of Things (IIoT).

[0268] And / or,

[0269] The first transmission resource is a configuration grant resource, namely a CG (Configured Grant) resource.

[0270] As another optional embodiment, step 11 includes:

[0271] The network-side device is configured for the terminal to use the first set of transmission resources that can be used to carry services of the first service type; wherein the transmission resource density in the first set of transmission resources is greater than the transmission resource density required by the services of the first service type.

[0272] It should be noted that the terminal does not expect all transmission resources in the first transmission resource set to be used exclusively for transmitting services of the first service type. For example, for transmission resources that are not selected, the network-side device can schedule other terminals to perform uplink transmission, or it can schedule the terminal to perform transmission of other service types on that transmission resource. Therefore, the terminal does not expect all transmission resources in the first transmission resource set to be used exclusively for transmitting services of the first service type.

[0273] As another optional embodiment, step 12 includes:

[0274] The first transmission resource is selected from the first set of transmission resources; wherein the first transmission resource satisfies a first condition, the first condition including at least one of the following:

[0275] t2-t1 is greater than or equal to the first time length;

[0276] t2-t1 is less than or equal to the second time length;

[0277] Wherein, the first time length is a non-negative number; the second time length is a non-negative number; t1 is the arrival time of the data packet; and t2 is the start time of the transmission of the first transmission resource.

[0278] Wherein, the arrival time of the data packet is the rated arrival time of the data packet;

[0279] or,

[0280] The arrival time of the data packet is the actual arrival time of the data packet.

[0281] As an optional embodiment, when the arrival time of the data packet is the nominal arrival time of the data packet, the method further includes:

[0282] The rated arrival time of the nth data packet is determined according to at least one of the following formulas, including:

[0283] t′ n =o traffic +n·T traffic

[0284] or,

[0285] t′ n =o traffic +n·T traffic +δ traffic

[0286] Where, t′ n For the rated arrival time of the nth data packet, o traffic δ represents the initial time-domain offset of the data. trafficT represents the jitter range at the time of data packet arrival. traffic For data period.

[0287] It should be noted that determining transmission resources based on actual arrival times minimizes data packet transmission latency. However, the base station does not know the arrival time of data packets from the terminal. Therefore, the base station needs to blindly detect which transmission resource the terminal is actually using among multiple possible resources. This increases the base station's detection complexity. Secondly, since the base station is unsure which transmission resource the terminal will actually use, it needs to reserve these resources for that terminal and cannot arbitrarily schedule them for other users to avoid interference. Consequently, this also reduces the resource utilization efficiency of transmission resources.

[0288] It should be further noted that although determining transmission resources based on the rated arrival time results in a larger data packet transmission delay, both the base station and the terminal can uniquely identify candidate transmission resources based on the rated data packet arrival time. Therefore, the complexity of blind detection on the base station side and the overhead of transmission resources are both low.

[0289] In this application embodiment, no specific limit is made on the arrival time of the data packet. In actual applications, factors such as the latency sensitivity of TSN services, the complexity of blind detection on the base station side, and the transmission resource overhead will be comprehensively considered to select a certain technical option (e.g., selecting the actual arrival time or selecting the rated arrival time).

[0290] Wherein, the first time length is the minimum processing delay between the arrival time of the data packet and the time when the data packet is carried in the network;

[0291] And / or, the second time length is the maximum transmission delay of the network where the data packet is located.

[0292] For example, let the first time length be denoted as τ. τ≥0, and is a non-negative number.

[0293] In one embodiment, τ = 0.

[0294] In another embodiment, τ represents the minimum processing delay between the arrival time t1 of the TSN data packet and the time t2 when the data packet can be carried in the network, which is a terminal capability parameter.

[0295] For example, let's denote the second time length as B. traffic B traffic ≥0 indicates a non-negative number.

[0296] In one embodiment, B traffic This represents the maximum tolerable transmission latency of the TSN network and is a service model parameter. In some embodiments, B trafficIt is also known as delay budget or packet delay budget (PDB).

[0297] Therefore, in this embodiment of the invention:

[0298] t2-t1≥τ

[0299] And / or,

[0300] t2-t1≤B traffic

[0301] Where τ is the first time length, B traffic This is the second time length.

[0302] In one embodiment,

[0303] τ≤t2-t1≤B traffic

[0304] As another optional embodiment, selecting the first transmission resource from the first set of transmission resources includes:

[0305] Select the m1th transmission resource from the first set of transmission resources as the first transmission resource;

[0306] Where m1 is the smallest integer that satisfies the first condition; the first condition includes at least one of the following:

[0307] t2-t1 is greater than or equal to the first time length;

[0308] t2-t1 is less than or equal to the second time length.

[0309] If no transmission resource can be found that satisfies the first condition, then data transmission is abandoned.

[0310] For example, let t be the starting transmission time of the k-th candidate transmission resource. k ,but:

[0311] m1 = mink

[0312] So that t k -t1≥τ.

[0313] For example, m1 is the smallest integer that satisfies t2-t1 being greater than or equal to the first time length, or m1 is the smallest integer that satisfies t2-t1 being less than or equal to the second time length, or m1 is the smallest integer that simultaneously satisfies t2-t1 being greater than or equal to the first time length and t2-t1 being less than or equal to the second time length.

[0314] Assume that the starting transmission time of the k-th transmission resource is t. k ,but:

[0315] m1 = mink

[0316] So that,

[0317] τ≤t k -t1≤B traffic

[0318] If no transmission resource k can be found that satisfies the condition...

[0319] τ≤t k -t1≤B traffic

[0320] Then data transmission is abandoned.

[0321] As another optional embodiment, the second time length is greater than the first time length;

[0322] Furthermore, the difference between the second time length and the first time length is greater than or equal to the third time length; the third time length is a non-negative number.

[0323] Let δ be the jitter range at the arrival time of TSN data packets. traffic Then you can

[0324] t1=t′1+ε traffic (2)

[0325] Where t′1 represents the rated arrival time of the data packet, and ε traffic This indicates the time deviation between the actual arrival time of the data packet and the scheduled arrival time, and

[0326] -δ traffic ≤ε traffic ≤δ traffic

[0327] τ≤t2-t1≤B traffic (1)

[0328] Substituting formula (2) into formula (1) yields the following:

[0329] τ≤t2-(t′1+ε traffic )≤B traffic

[0330] Equivalent to

[0331] τ+ε traffic ≤t2-t′1≤B traffic +ε traffic (3)

[0332] For ε traffic For all possible values, in order for inequality (3) to always hold, we need to...

[0333] τ+ε traffic ≤B traffic +δ traffic

[0334] Further requirements

[0335] τ+δ traffic ≤B traffic -δ traffic

[0336] Equivalence requirements

[0337] B traffic -τ≥2·δ traffic

[0338] Where τ is the first time length, B traffic For the second time length, 2·δ traffic This is the third time length. That is, the third time length is a non-negative number, representing twice the maximum jitter range at the time of data arrival.

[0339] As another optional embodiment, step 12 includes:

[0340] Based on the arrival time of the nth data packet, select the m2th transmission resource from the first transmission resource set as the first transmission resource to carry the nth data packet;

[0341] Where m2 is related to n.

[0342] The method further includes:

[0343] Determine the value of m2 based on the first formula or the second formula;

[0344] The first formula is:

[0345]

[0346] The second formula is:

[0347]

[0348] Where A is a constant or configured via higher-level signaling, and T resource For the transmission resource cycle; T traffic For data period.

[0349] As an optional embodiment, the method further includes:

[0350] Determine the value of A based on the third, fourth, or fifth formula; where,

[0351] The third formula is:

[0352]

[0353] The fourth formula is:

[0354] A = 0

[0355] The fifth formula is:

[0356]

[0357] Among them, T resource For transmission resource cycle; o resource The initial time-domain offset of the transmitted resources; o traffic δ represents the initial time-domain offset of the data. traffic τ represents the jitter range at the arrival time of the nth data packet; τ is the minimum processing delay between the arrival time of the data packet and the time when the data packet is carried in the network.

[0358] As another alternative embodiment, A can be calculated in other ways, for example:

[0359]

[0360] The term "round" can represent rounding up, rounding down, or rounding to the nearest integer.

[0361] For example, the period of a TSN data packet is denoted as T. traffic The candidate resource period (such as CG resource) used to carry TSN data packets in the network is denoted as T. resource The jitter range of the arrival time of TSN data packets is denoted as δ. traffic (That is, half of the third time length), the maximum tolerable transmission delay of the TSN network is B. traffic (i.e., the second time length) is the minimum processing delay between the arrival time t1 of the TSN data packet and the time t2 when the data packet can be carried in the network. (i.e., the first time length) is denoted as τ, that is, t2>t1, and t2-t1≥τ.

[0362] Offset the start time of the TSN data packet to 0. traffic Then the time when the nth TSN data packet arrives at the network is

[0363]

[0364] in,

[0365] -δ traffic ≤ε traffic ≤δ traffic

[0366] Given a period T for the candidate resource configuration in the network to carry TSN packets resource and the offset of the starting time is o resource Then the starting transmission time of the k-th candidate resource is

[0367]

[0368] Then, using the method described above, we find the smallest integer m that satisfies the first condition, such that...

[0369] m2=min k

[0370] So that,

[0371]

[0372] And / or,

[0373]

[0374] Substituting formulas (4) and (5) into formula (6) yields the following result:

[0375] (o resource +k·T resource )-(o traffic +n·T traffic +ε traffic )≥τ

[0376] Right now

[0377]

[0378] because

[0379] -δ traffic ≤ε traffic ≤δ traffic

[0380] To ensure that formula (8) always holds true, it is required that

[0381]

[0382] Right now

[0383]

[0384] Therefore, m2 = min k can be equivalent to,

[0385] Method 1:

[0386]

[0387] Among them, T resourceT is a candidate resource period used to carry TSN data packets in a 3GPP network; traffic The period of TSN data packets; o resource The start time offset configured for candidate resources carrying TSN packets; traffic δ represents the start time offset of the TSN data packet. traffic τ represents the jitter range of the arrival time of the TSN data packet; τ is the minimum processing delay (i.e., the first time length) between the arrival time of the TSN data packet and the time when the data packet can be carried in the 3GPP network.

[0388] δ traffic This is recorded as the fourth time length; This indicates rounding up.

[0389] Method 2: In another embodiment, setting

[0390] o resource =o traffic +δ traffic +τ

[0391] at this time,

[0392]

[0393] As an optional embodiment, the method further includes:

[0394] According to the sixth formula, the starting time-domain offset o of the transmission resource is determined. resource The sixth formula is:

[0395] o resource =o traffic +δ traffic +τ

[0396] or,

[0397] o resource =round{o traffic +δ traffic +τ}

[0398] Among them, o traffic δ represents the initial time-domain offset of the data. traffic τ represents the jitter range of the data packet arrival time; τ represents the minimum processing delay between the arrival time of the data packet and the time when the data packet is carried in the network; round indicates rounding up, rounding down, or rounding to the nearest integer.

[0399] Wherein, the starting time-domain offset o of the transmission resource resource and / or the starting time-domain offset of the data o trafficThe calculation starts from a pre-set absolute time. For example, the calculation starts from 00:00:00 on 1 January 1900.

[0400] It should be noted that the terminal does not expect all transmission resources in the first transmission resource set to be used only for transmitting services of the first service type;

[0401] And / or,

[0402] The terminal expects that transmission resources in the first transmission resource set that are not used to carry the data packet can be used to transmit other services of the terminal, or uplink or downlink services of other terminals.

[0403] In summary, this invention addresses the mismatch between the period values ​​in the time information of TSN services and the period values ​​in existing networks in application scenarios where TSN services are carried by networks. It proposes a method where the network-side device pre-configures a first set of transmission resources for the terminal; and when a data packet arrives, it selects resources from the first set of transmission resources that meet the constraints to carry the data packet. This invention offers flexible configuration and effectively reduces the overhead of data transmission resources while ensuring low latency for TSN services.

[0404] like Figure 2 As shown, this embodiment of the invention also provides a method for determining transmission resources, applied to a network-side device, including:

[0405] Step 21: Configure the first set of transmission resources for the terminal;

[0406] Step 22: Based on the arrival time of the data packet, determine the first transmission resource in the first transmission resource set for carrying the data packet;

[0407] Step 23: Receive the uplink signal sent by the terminal according to the determined first transmission resource.

[0408] As an optional embodiment, the data packet is a data packet of a first service type; optionally, the first service type is latency-sensitive, for example, the first service type is a latency-sensitive network (TSN) generated by the Industrial Internet of Things;

[0409] And / or,

[0410] The first transmission resource is a configuration grant resource, namely a CG (Configured Grant) resource.

[0411] As another optional embodiment, step 21 includes:

[0412] Configure the terminal with the first set of transmission resources that can be used for services of the first service type; wherein the transmission resource density in the first set of transmission resources is greater than the transmission resource density required by services of the first service type.

[0413] It should be noted that the terminal does not expect all candidate transmission resources in the first transmission resource set to be used exclusively for transmitting services of the first service type. For example, for transmission resources that are not selected, the network-side device can schedule other terminals to perform uplink transmission, or it can schedule the terminal to perform transmission of other service types on that transmission resource. Therefore, the terminal does not expect all transmission resources in the transmission resource set to be used exclusively for transmitting services of the first service type.

[0414] As another optional embodiment, step 22 includes:

[0415] The first transmission resource is selected from the first set of transmission resources; wherein the first transmission resource satisfies a first condition, the first condition including at least one of the following:

[0416] t2-t1 is greater than or equal to the first time length;

[0417] t2-t1 is less than or equal to the second time length;

[0418] Wherein, the first time length is a non-negative number; the second time length is a non-negative number; t1 is the arrival time of the data packet; and t2 is the start time of the transmission of the first transmission resource.

[0419] Wherein, the arrival time of the data packet is the rated arrival time of the data packet;

[0420] or,

[0421] The arrival time of the data packet is the actual arrival time of the data packet.

[0422] As an optional embodiment, when the arrival time of the data packet is the nominal arrival time of the data packet, the method further includes:

[0423] The rated arrival time of the nth data packet is determined according to at least one of the following formulas, including:

[0424] t′ n =o traffic +n·T traffic

[0425] or,

[0426] t′ n =o traffic +n·T traffic +δ traffic

[0427] Where, t′ n For the rated arrival time of the nth data packet, o traffic δ represents the initial time-domain offset of the data. traffic T represents the jitter range at the time of data packet arrival. traffic For data period.

[0428] It should be noted that determining transmission resources based on actual arrival times minimizes data packet transmission latency. However, the base station does not know the arrival time of data packets from the terminal. Therefore, the base station needs to blindly detect which transmission resource the terminal is actually using among multiple possible resources. This increases the base station's detection complexity. Secondly, since the base station is unsure which transmission resource the terminal will actually use, it needs to reserve these resources for that terminal and cannot arbitrarily schedule them for other users to avoid interference. Consequently, this also reduces the resource utilization efficiency of transmission resources.

[0429] It should be further noted that although determining transmission resources based on the rated arrival time results in a larger data packet transmission delay, both the base station and the terminal can uniquely identify candidate transmission resources based on the rated data packet arrival time. Therefore, the complexity of blind detection on the base station side and the overhead of transmission resources are both low.

[0430] In this application embodiment, no specific limit is made on the arrival time of the data packet. In actual applications, factors such as the latency sensitivity of TSN services, the complexity of blind detection on the base station side, and the transmission resource overhead will be comprehensively considered to select a certain technical option (e.g., selecting the actual arrival time or selecting the rated arrival time).

[0431] In addition, if the arrival time of the data packet is the actual arrival time of the data packet, since the network-side device does not know the actual arrival time of the data packet, the network-side device can blindly detect uplink transmission on multiple candidate resources corresponding to the dynamic range of the estimated actual arrival time.

[0432] Wherein, the first time length is the minimum processing delay between the arrival time of the data packet and the time when the data packet is carried in the network;

[0433] And / or,

[0434] The second time length is the maximum transmission delay of the network where the data packet is located.

[0435] For example, let the first time length be denoted as τ. τ≥0, and is a non-negative number.

[0436] In one embodiment, τ = 0.

[0437] In another embodiment, τ represents the minimum processing delay between the arrival time t1 of the TSN data packet and the time t2 when the data packet can be carried in the network, which is a terminal capability parameter.

[0438] For example, let's denote the second time length as B. traffic B traffic ≥0 indicates a non-negative number.

[0439] In one embodiment, B traffic This represents the maximum tolerable transmission delay of the TSN network and is a service model parameter.

[0440] Therefore, in this embodiment of the invention:

[0441] t2-t1≥τ

[0442] And / or,

[0443] t2-t1≤B traffic

[0444] Where τ is the first time length, B traffic This is the second time length.

[0445] In one embodiment,

[0450] t2-t1 is greater than or equal to the first time length;

[0451] t2-t1 is less than or equal to the second time length.

[0452] If no transmission resource can be found that satisfies the first condition, then data transmission is abandoned.

[0453] For example, let t be the starting transmission time of the k-th candidate transmission resource. k ,but:

[0454] m1 = mink

[0455] So that t k -t1≥τ.

[0456] For example, m1 is the smallest integer that satisfies t2-t1 being greater than or equal to the first time length, or m1 is the smallest integer that simultaneously satisfies t2-t1 being less than or equal to the second time length, or m1 is the smallest integer that simultaneously satisfies t2-t1 being greater than or equal to the first time length and t2-t1 being less than or equal to the second time length.

[0457] Assume that the starting transmission time of the k-th transmission resource is t. k ,but:

[0458] m1 = mink

[0459] So that,

[0460] τ≤t k -t1≤B traffic

[0461] If no transmission resource k can be found that satisfies the condition...

[0462] τ≤t k -t1≤B traffic

[0463] Then data transmission is abandoned.

[0468] Where t′1 represents the nominal arrival time of the data packet, and ε traffic This indicates the time deviation between the actual arrival time of the data packet and the scheduled arrival time, and

[0469] -δ traffic ≤ε traffic ≤δ traffic

[0470] τ≤t2-t1≤B traffic (1)

[0471] Substituting formula (2) into formula (1) yields the following:

[0472] τ≤t2-(t′1+ε traffic )≤Btraffic

[0473] Equivalent to

[0474] τ+ε traffic ≤t2-t′1≤B traffic +ε traffic (3)

[0475] For ε traffic For all possible values, in order for inequality (3) to always hold, we need to...

[0479] Equivalence requirements

[0480] B traffic -τ≥2·δ traffic

[0481] Where τ is the first time length, B traffic For the second time length, 2·δ traffic This is the third time length. That is, the third time length is a non-negative number, representing twice the maximum jitter range at the time of data arrival.

[0482] As another optional embodiment, step 22 includes:

[0483] Based on the arrival time of the nth data packet, select the m2th transmission resource from the first transmission resource set as the first transmission resource to carry the nth data packet;

[0488]

[0489] The second formula is:

[0490]

[0491] Where A is a constant or configured via higher-level signaling, and Tresource For the transmission resource cycle; T traffic For data period.

[0492] As an optional embodiment, the method further includes:

[0493] Determine the value of A based on the third, fourth, or fifth formula; where,

[0494] The third formula is:

[0495]

[0496] The fourth formula is:

[0497] A = 0

[0498] The fifth formula is:

[0500] Among them, T resource For transmission resource cycle; o resource The initial time-domain offset of the transmitted resources; o traffic δ represents the initial time-domain offset of the data. traffic τ represents the jitter range at the arrival time of the nth data packet; τ is the minimum processing delay between the arrival time of the data packet and the time when the data packet is carried in the network.

[0501] For example, the period of a TSN data packet is denoted as T. traffic The candidate resource period (such as CG resource) used to carry TSN data packets in the network is denoted as T. resource The jitter range of the arrival time of TSN data packets is denoted as δ. traffic (That is, half of the third time length), the maximum tolerable transmission delay of the TSN network is B. traffic (i.e., the second time length) is the minimum processing delay between the arrival time t1 of the TSN data packet and the time t2 when the data packet can be carried in the network. (i.e., the first time length) is denoted as τ, that is, t2>t1, and t2-t1≥τ.

[0510] So that,

[0511]

[0512] And / or,

[0513]

[0514] Substituting formulas (4) and (5) into formula (6) yields the following result:

[0515] (o resource +k·T resource )-(o traffic +n·T traffic +ε traffic )≥τ

[0516] Right now

[0517]

[0518] because
