Description

Technical Field

[0001] This application relates to the field of Internet of Things (IoT) technology, and more specifically, to a parallel detection method and apparatus for IoT terminals. Background Technology

[0002] Currently, 5G NB-IoT (Narrow Band Internet of Things) technology boasts advantages such as wide coverage, low power consumption, and support for massive connectivity, leading to its widespread adoption. However, in terms of transmission, NB-IoT utilizes relatively few wireless resources to meet downlink transmission requirements due to the higher power of base stations. Conversely, the lower power of terminals necessitates the use of more wireless resources to meet uplink transmission requirements. Therefore, uplink transmission becomes a limiting factor for NB-IoT capacity.

[0003] For the uplink of NB-IoT, two physical channels are defined: NPRACH (Narrowband Physical Random Access Channel) and NPUSCH (Narrowband Physical Uplink Shared Channel). Since NB-IoT smart IoT terminals are activated simultaneously, the probability of NPRACH collisions is relatively high. Therefore, NPRACH is not suitable for deployment scenarios with parallel detection.

[0004] To reduce after-sales service costs, related technologies typically employ batch testing. This involves testing the communication performance of each NB-IoT smart terminal under specified RSRP (Reference Signal Receiving Power) and SINR (Signal to Interference plus Noise Ratio). However, this method is prone to problems. If the number of NB-IoT smart terminals to be tested in the same batch is too large, multiple testing cycles are required to test all terminals. Conversely, if the number of NB-IoT smart terminals to be tested in the same batch is too small, the testing capacity of the NB-IoT base station is not fully utilized within one testing cycle. In other words, both excessive and insufficient numbers of NB-IoT smart terminals in the same batch will lead to a mismatch between the number of NB-IoT smart terminals that the NB-IoT network can test in parallel and the number of NB-IoT smart terminals to be tested in each batch, resulting in decreased testing efficiency.

[0005] There is currently no effective solution to the above problems. Summary of the Invention

Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0024] It should be noted that the terms "first," "second," etc., used in the specification, claims, and drawings of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of this application described herein can be implemented in orders other than those illustrated or described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.

[0025] To better understand the embodiments of this application, the following is a translation and explanation of some nouns or terms that appear in the description of the embodiments of this application:

[0026] NB-IoT (Narrow Band Internet of Things) is an important branch of the universal interconnected network. Built on cellular networks, NB-IoT consumes only about 180kHz of bandwidth and can be directly deployed on GSM, UMTS, or LTE networks to reduce deployment costs and enable smooth upgrades. Therefore, it features wide coverage, high connectivity, high speed, low cost, low power consumption, and superior architecture. Furthermore, NB-IoT uses licensed frequency bands and can be deployed in three ways: in-band, guard band, or independent carrier, coexisting with existing networks.

[0027] NPRACH (Narrowband Physical Random Access Channel): Used for the random access procedure of user equipment (UEs). The random access procedure is a crucial means for UEs to transition from an idle state to a connected state by acquiring dedicated channel resources. NPRACH has a subcarrier spacing of 3.75kHz and uses a singleton transmission method. Furthermore, NB-IoT can flexibly configure NPRACH for UEs, supporting time-frequency domain multiplexing, but not code division multiplexing.

[0028] NPUSCH (Narrowband Physical Uplink Shared Channel): Used to transmit uplink data and uplink control information, it has two formats. NB-IoT determines the minimum scheduling resource unit (RU) for user equipment based on the format, subcarrier spacing, and number of time slots. One format carries the uplink shared transmission channel and uplink service data or signaling, using Turbo codes, and its resource unit includes both Singleton and Multiton modes. The other format carries uplink control information, transmitting HARQ-ACK / NACK (HARQ, Hybrid Automatic Repeat reQuest) indicating whether the NPUSCH transmission was successfully received; this format only supports Singleton mode.

[0029] Example 1

[0030] Currently, under specified RSRP and SINR conditions, if the number of NB-IoT smart IoT terminals to be tested in each batch is too large or too small, it will lead to a mismatch between the number of NB-IoT smart IoT terminals that the NB-IoT network can concurrently support and the number of NB-IoT smart IoT terminals to be tested in each batch, resulting in low testing efficiency.

[0031] To address the aforementioned issues, this application provides a parallel detection method for IoT terminals. The parallel detection method for IoT terminals will be described in detail in the embodiments below.

[0032] It should be noted that the steps shown in the flowchart in the accompanying drawings can be executed in a computer system such as a set of computer-executable instructions, and although a logical order is shown in the flowchart, in some cases the steps shown or described may be executed in a different order than that shown here.

[0033] Figure 1 This is a flowchart illustrating an optional parallel detection method for an IoT terminal according to an embodiment of this application, as shown below. Figure 1 As shown, the method includes at least steps S102-S106, wherein:

[0034] Step S102: Determine the first narrowband physical random access channel resources and the first narrowband physical uplink shared channel resources required to detect a single IoT terminal under target detection conditions.

[0035] The target detection conditions include at least the following: a preset reference signal receiving power and a signal interference noise power ratio.

[0036] In this embodiment of the application, the reference signal received power RSRP signal interference noise power ratio SINR can be set as follows: RSRP∈{-130,-125,-120,-115,-110,-105,-100,-95,-90}dBm, and SINR∈{-5,0,5,10,15}dB.

[0037] For example, with a reference signal received power (RSRP) of -110 dBm and a signal-to-interference-noise ratio (SINR) of 5 dB, first determine the occupancy of a single NPRACH transmitted by a single NB-IoT smart IoT terminal. SCS (3.75 kHz)·ms, and the number of repetitions Therefore, the first narrowband physical random access channel resources required for a single NB-IoT IoT terminal to perform detection for:

[0038]

[0039] in, The unit is SCS (3.75 kHz)·ms.

[0040] At the same time, it is determined that a single NB-IoT smart IoT terminal needs to send n uplink transmissions. N PUSCH1 = 8 NPUSCH and n in format 1NPUSCH2 = 4 format 2 NPUSCH, where N is the smallest scheduling resource unit of the user equipment. RU =8, If there are 1, then the NPUSCH space occupied by the transmission format 1 will not be repeated. SCS (3.75 kHz)·ms, number of repetitions The NPUSCH space occupied by non-repeating transmission format 2 SCS (3.75 kHz)·ms, number of repetitions

[0041] Therefore, using the above parameters, the first narrowband physical uplink shared channel resources required for a single NB-IoT IoT terminal to perform detection are calculated using the following formula.

[0042]

[0043] in, The unit is also SCS (3.75 kHz)·ms.

[0044] Step S104: Determine the preset total resources of narrowband physical random access channels and narrowband physical uplink shared channels.

[0046] Specifically, in this embodiment of the application, the time domain resources of NPRACH can be set to... and At the same time, the frequency domain resources of NPRACH are set as and Each SCS occupies 3.75kHz bandwidth, therefore, according to and Determine the total resources of the narrowband physical random access channel Its specific expression is:

[0047]

[0048] in, The unit is SCS (3.75 kHz)·ms.

[0049] Next, under the specified RSRP and SINR conditions, the duration T1 of detection for a single NB-IoT smart IoT terminal is determined. Simultaneously, the resource utilization threshold β of the NPUSCH is obtained, where β ranges from 0 to 100%. Therefore, based on the duration T1, the resource utilization threshold β, and the total resources of the narrowband physical random access channel... Determine the total resources of the narrowband physical uplink shared channel. The calculation formula is as follows:

[0050]

[0051] in, The unit is also SCS (3.75 kHz)·ms.

[0052] Step S106: Determine the first number of IoT terminals that can be detected in parallel based on the total resources of the narrowband physical random access channel and the first narrowband physical random access channel resources, and determine the second number of IoT terminals that can be detected in parallel based on the total resources of the narrowband physical uplink shared channel and the first narrowband physical uplink shared channel resources.

[0053] Optionally, the first quantity can be determined by: obtaining a preset collision threshold value for the narrowband physical random access channel; and determining the first quantity of IoT terminals that can be detected in parallel based on the total resources of the narrowband physical random access channel, the first narrowband physical random access channel resources, and the collision threshold value.

[0054] Specifically, firstly, based on the total resources of the narrowband physical random access channel. and the first narrowband physical random access channel resources The number of NPRACHs that can be hosted on these resources is calculated using the following formula:

[0055]

[0056] Then, the collision threshold α of the narrowband physical random access channel is obtained, where the value of α ranges from 0 to 100%.

[0057] Finally, based on the collision threshold α and the total resources of the narrowband physical random access channel... and the first narrowband physical random access channel resources The first number N of IoT terminals that can be detected in parallel is calculated using the following formula.

[0059]

[0060] Step S108: Determine the target number of IoT terminals that can be detected in parallel based on the first quantity and the second quantity, and perform parallel detection on the target number of IoT terminals under the target detection condition.

[0061] As an optional implementation, the smaller of the first quantity and the second quantity is taken as the target quantity; under target detection conditions, the target number of IoT terminals are detected in parallel using the preset total resources of narrowband physical random access channels and the total resources of narrowband physical uplink shared channels.

[0062] Furthermore, under target detection conditions, the total resources of the target narrowband physical random access channel and the total resources of the target narrowband physical uplink shared channel are used to perform parallel detection on the target number of IoT terminals, thereby effectively improving the enterprise's online parallel detection capability and reducing the enterprise's production costs.
