Description

Technical Field

[0001] This invention relates to the technical field of wireless communication channel segmentation, and more specifically, to a short-range wireless communication channel segmentation method, storage medium, and electronic device. Background Technology

[0002] Current short-range protocols typically divide a channel into primary and backup channels. When one channel is interfered with, the interfered channel is abandoned, and data is transmitted and received through the other channel. However, when a channel is subjected to narrowband, short-duration, or low-power interference, such interference does not completely destroy the data on the entire channel; it may only cause errors in some of the data on that channel, while the correct data on that channel can still be reused.

[0003] Therefore, given that some data from the interfered channel can still be reused, we urgently need to develop a novel method for short-range wireless communication channel segmentation. Summary of the Invention

[0010] Preferably, step S2 further includes: step S25: when the channel quality of both the first channel and the second channel is poor, or the channel quality of the first channel is good and the channel quality of the second channel is poor, or the channel quality of the first channel is poor and the channel quality of the second channel is good, step S26 is executed; step S26: the transmitting end transmits wireless data to the receiving end through the first channel and / or the second channel with lower noise level according to the existing data protocol.

[0012] Preferably, in step S1, if the judgment result is negative, step S23 is executed directly.

[0013] Preferably, when the transmitting end transmits wireless data to the receiving end through the first channel and the second channel, the first channel and the second channel allocate subcarriers according to their respective bandwidth positions by referring to the resource units (RU) of the existing data protocol.

[0030] In one embodiment of the present invention, when the transmitting end transmits wireless data to the receiving end through the first channel and the second channel, the first channel and the second channel allocate subcarriers according to their respective bandwidth positions by referring to the resource units (RU) of the existing data protocol.

[0036] The following specific embodiment illustrates the short-range wireless communication channel segmentation method of the present invention. This specific embodiment of the short-range wireless communication channel segmentation method can be applied to the fields of communication technology, 5G networks, and the industrial internet. The short-range wireless communication channel is divided into a first channel and a second channel; wherein the first channel is the primary channel, and the second channel is a backup channel; the transmitting end transmits wireless data to the receiving end through the first channel and / or the second channel; the short-range wireless communication channel segmentation method of this specific embodiment mainly includes: channel preparation and measurement, data transmission, pilot section, and data section. Each stage is implemented through several small steps, as detailed below: (1) Channel preparation and measurement, including the following steps: Step 1: Divide the primary and backup channels according to the pattern. The pattern can be set, such as dividing an 80M bandwidth into 40M on the left and 40M on the right as the primary and backup channels, respectively. Alternatively, the left channel can be 20M and the right channel can be 60M as the primary and backup channels. Step 2: Primary and Backup Channel Quality Detection: Before communication begins, channel measurements are performed using existing standard protocols, or the noise levels of the primary and backup channels are directly statistically analyzed at the physical layer to determine the channel quality (the noise level is directly compared with a noise threshold; a value greater than the threshold indicates good quality, and a value less than the threshold indicates poor quality. The threshold can be set according to the communication rate requirements). Step 3: If both the primary and backup channels have good quality, they can be merged into one channel. Step 4: If either the primary or backup channel has poor quality, mark the good channel as good and the poor channel as poor. Step 5: If both are poor, then both the primary and backup channels are marked as poor; Step 6: Alternatively, the channel can be directly divided into primary and backup channels without measurement (real-time evaluation will be performed later).

[0037] (2) Data transmission, including the following steps: Step 1: For those merged into one channel, transmission can be performed according to existing standard protocols; Step 2: For those split into two channels, implement the following four scenarios; a: One good, one bad; b: Both good; c: Both bad; d: Two channels that have not been measured; These can be categorized into two types: Option 1: Send on only one channel; Option 2: Send through both channels, with one channel used as a backup for retransmission.

[0038] The choice of which scheme to use for the four scenarios a, b, c, and d can be freely configured based on the actual test scenario. For example, scheme 1 can be used for a and c, while scheme 2 can be used for b and d.

[0039] Option 1: Send only on one channel and follow the standard protocol process; Option 2: Redesign pilot and data transmission modes: (3) Furthermore, each channel has its own pilot and transmits the same content. The pilot section specifically includes the following steps: Step 1: For scenario a: one good and one bad, demodulate only the pilot that is good; Step 2: For scenarios b, c, and d: Before demodulation, correlation operations are performed on the pilot and the pilot local sequence to determine which correlation peak energy is higher, i.e., which has a higher signal-to-noise ratio, in order to determine the pilot of the good demodulation channel (real-time evaluation).

[0040] (4) Further, regarding the data portion, the specific steps include: Step 1: The primary and backup channels send the same data, or send data that has been redundantly encoded and split into two packets, with each channel sending one packet.

[0041] In this process, the primary channel allocates subcarriers according to the bandwidth position of the primary channel by referring to the resource unit (RU) of the standard protocol, and the backup channel allocates subcarriers in the same way according to the bandwidth position of the backup channel.

[0042] In this specific embodiment, for existing primary and backup channels, existing technologies directly discard a channel upon detecting interference, which reduces the bandwidth of that channel and results in bandwidth waste. This invention proposes continuing to receive information from the channel even with interference and re-dividing the pilot and data channels to fully utilize the channels.

[0043] In this embodiment, the present invention first performs channel evaluation to determine the channel quality of the primary and backup channels; if both are good, full bandwidth transmission is performed. If one is poor, the primary and backup channels transmit the same data content. Simultaneously, primary and backup data are received, and data that is correct in both primary and backup data is compared and verified. If all received correct information can be pieced together to form a complete data packet, then the reception is correct.

[0044] In this specific embodiment, by evaluating and classifying the channels and changing the way the primary and backup channels are used, the goal of making full use of the bandwidth is achieved.

[0045] The above description is merely a preferred embodiment of the present invention and is not intended to limit the invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
