[0034] The principle and spirit of the present disclosure are explained in detail below with reference to several representative embodiments of the present disclosure.

[0035] As described in the background art, in order to prevent mutual interference between users in different industries, different radio frequency bands are allocated to different industries.

[0036] Specifically, radio spectrum resources are a precious natural resource. With the rapid development of wireless technology, wireless applications with high data rate requirements such as mobile high-speed data networks and wireless multimedia applications have been widely deployed. The number of wireless users has exploded, and the demand for spectrum has also increased. How to use limited spectrum resources to meet the spectrum requirements of various wireless applications has become a hot research topic. The current spectrum resources are all regulated according to a fixed spectrum allocation method to regulate the use rights of wireless spectrum to prevent interference between different service users.

[0037] Take the power industry as an example. In the radio frequency band corresponding to the power industry, the channel environment is complex. There is adjacent channel interference from data transmission radio stations of other industry users, and there is in-band interference from power users' negative control data transmission radio stations. Therefore, the terminals of industry-aware users need to monitor channels and detect available and idle frequencies for information transmission to ensure communication quality.

[0038] Specifically, as a specific example, the power industry is allocated authorization for 40 discrete frequency points within the 223MHz-235MHz frequency band, and the frequency band is allocated to 7 industry users.

[0039] For example, for the 40 discrete frequency points authorized by the power industry, the cognitive user's terminal searches for 40 discrete channels and forms a new logical channel with the available channels searched; the cognitive user can use all idle channels on the logical channel for data transmission at the same time; because the terminal moves randomly, the channel usage will also change. Therefore, it is necessary to periodically monitor the communication quality of each channel being used by the terminal through spectrum sensing, that is, to monitor the channel to determine whether the terminal needs to switch the current channel due to the deterioration of the channel communication quality. If all channels in the current logical channel are busy, the cognitive user's terminal will terminate the transmission and switch to the channel search state again.

[0040] However, the inventors of the present disclosure discovered that the monitoring period of channel monitoring will affect the performance of data transmission: on the one hand, if the monitoring period is too long, it may cause interference to the authorized signal or waste some possible spectrum access opportunities; on the other hand, if the monitoring period is too short, it will cause a large monitoring overhead.

[0041] In order to solve the above problems, the present disclosure provides a channel monitoring scheme, which specifically includes: determining channels that meet access conditions to form a logical channel set; determining idle channels from the logical channel set, determining target channels from the idle channels, and transmitting data based on the target channels; monitoring the target channels based on a predetermined monitoring period to obtain monitoring results, wherein the monitoring period is obtained based on indicator data of each channel in the target channel within one monitoring period, and the indicator data includes: average missed spectrum opportunities, time proportion of idle spectrum opportunities wasted due to monitoring, and time proportion of interference with authorized signals; re-determining the target channel based on the monitoring results. Channel monitoring is performed through the monitoring period determined by the present disclosure, while taking into account monitoring overhead and access opportunities, thereby reducing waste of access opportunities while reducing monitoring overhead.

[0042] After introducing the basic principles of the present disclosure, various non-limiting embodiments of the present disclosure are described in detail below.

[0043] refer to Figure 1 , which is a schematic diagram of an application scenario of the channel monitoring method provided by an exemplary embodiment of the present disclosure.

[0044] This application scenario includes a terminal device 110 and radio spectrum resources.

[0045] The terminal device 110 may be a device including a wireless signal receiver, which is a device that only has a wireless signal receiver without transmission capability, or a device including receiving and transmitting hardware, which is a device that has receiving and transmitting hardware capable of two-way communication over a two-way communication link. Such devices may include: cellular or other communication devices, which have a single line display or a multi-line display or a cellular or other communication device without a multi-line display; PCS (Personal Communications Service) which may combine voice, data processing, fax and / or data communication capabilities; PDA (Personal Digital Assistant) which may include a radio frequency receiver, a pager, Internet / intranet access, a web browser, a notepad, a calendar and / or a GPS (Global Positioning System) receiver; a conventional laptop and / or palmtop computer or other device, which has and / or includes a conventional laptop and / or palmtop computer or other device with and / or including a radio frequency receiver. The "terminal" or "terminal device" used herein may be portable, transportable, installed in a vehicle (air, sea and / or land), or adapted and / or configured to operate locally, and / or in a distributed form, at any other location on the earth and / or in space. The "terminal" or "terminal device" used herein may also be a communication terminal, an Internet terminal, a music / video playing terminal, such as a PDA, a MID (Mobile Internet Device) and / or a mobile phone with a music / video playing function, or a smart TV, a set-top box and other devices.

[0046] When the channel monitoring method is run on the terminal device 110, the terminal device 110 is used to provide a channel monitoring service to the user of the terminal device 110. The terminal device 110 determines that the channels that meet the access conditions constitute a logical channel set; the terminal device 110 determines an idle channel from the logical channel set, determines a target channel from the idle channel, and performs data transmission based on the target channel; the terminal device 110 monitors the target channel based on a predetermined monitoring period to obtain a monitoring result, wherein the monitoring period is obtained based on the indicator data of each channel in the target channel within a monitoring period, and the indicator data includes: average missed spectrum opportunities, the time ratio of idle spectrum opportunities wasted due to monitoring, and the time ratio of interference with authorized signals; the terminal device 110 re-determines the target channel based on the monitoring result, so as to help the user's terminal device 110 to perform data transmission based on the re-determined target channel.

[0047] Combine the following Figure 1The channel monitoring method according to the exemplary embodiment of the present disclosure is described by using the application scenario. It should be noted that the above application scenario is only shown to facilitate understanding of the spirit and principle of the present disclosure, and the embodiments of the present disclosure are not limited in this respect. On the contrary, the embodiments of the present disclosure can be applied to any applicable scenario.

[0048] refer to Figure 2 , which is a flow chart of a channel monitoring method provided by an exemplary embodiment of the present disclosure.

[0049] The exemplary embodiment of the present disclosure provides a channel monitoring method, comprising the following steps:

[0050] Step S210: Determine channels that meet access conditions to form a logical channel set.

[0051] In this exemplary embodiment, determining that channels meeting the access condition constitute a logical channel set includes:

[0052] Channel search is performed on discrete channels in authorized discrete frequency points to obtain channels that meet the access conditions to form the logical channel set.

[0053] In specific implementation, the terminal of the cognitive user performs channel search for authorized discrete frequencies and discrete channels in the industry wireless communication system of its industry, determines available channels that meet the access conditions, and groups these channels that meet the access conditions into a logical channel set.

[0054] For example, in the electric power wireless communication system, the terminal of the cognitive user performs channel search for 40 discrete frequency points authorized by the electric power industry, and determines the available channels to form a logical channel set.

[0055] Step S220: determine an idle channel from the logical channel set, determine a target channel from the idle channel, and perform data transmission based on the target channel.

[0056] In this exemplary embodiment, determining an idle channel from the logical channel set includes:

[0057] In response to determining that the idle channel does not exist in the logical channel set, channels that meet the access condition are re-determined to constitute the logical channel set until the idle channel exists in the logical channel set.

[0058] In this exemplary embodiment, determining the target channel from the idle channels includes:

[0059] determining a target number of the target channels based on the monitoring period;

[0060] The target number of channels is determined from the idle channels as the target channels.

[0061] During specific implementation, the terminal of the cognitive user may use one idle channel in the current logical channel set for data transmission, or may simultaneously use multiple idle channels in the logical channel set for data transmission, so as to improve transmission efficiency.

[0062] Step S230, monitor the target channel based on a predetermined monitoring period to obtain a monitoring result, wherein the monitoring period is obtained based on indicator data of each channel in the target channel within one of the monitoring periods, and the indicator data include: average missed spectrum opportunities, time proportion of idle spectrum opportunities wasted due to monitoring, and time proportion of interference with authorized signals.

[0063] In this exemplary embodiment, the monitoring period is obtained based on the indicator data of each channel in the target channel within one monitoring period, including:

[0064] The monitoring period is calculated with the purpose of minimizing the sum of the average lost spectrum opportunities, the time proportion of the idle spectrum opportunities wasted due to monitoring, and the time proportion of the interference authorization signal for each channel in the target channel within one monitoring period.

[0065] In this exemplary embodiment, the monitoring of the target channel based on a predetermined monitoring period to obtain a monitoring result includes:

[0066] Determining a monitoring duration for monitoring the target channel based on the monitoring period;

[0067] When each monitoring period arrives, the target channel is monitored based on the monitoring duration to obtain the monitoring result.

[0068] In this exemplary embodiment, the monitoring time for monitoring the target channel based on the predetermined monitoring period is half of the monitoring period.

[0069] In this exemplary embodiment, the monitoring period is obtained based on the indicator data of each channel in the target channel within one monitoring period, including being determined by the following formula:

[0070]

[0071] in, is the monitoring period, the function of arg min is to make the following formula reach the minimum value of the variable, λ1 and λ2 are the preset weight factors, K is the number of channels monitored, and They represent the average spectrum loss opportunities and the time proportion of interference to authorized users of the i-th channel in a monitoring period, respectively. i (T p ) represents the proportion of idle spectrum opportunity time wasted due to monitoring of channel i within a monitoring cycle.

[0072] In specific implementation, the cognitive user's terminal periodically monitors each channel in use to ensure the communication quality. For a channel in use, the communication quality of the channel will be monitored in each monitoring cycle to determine whether the channel is suitable for continued data transmission; if the monitoring result shows that the communication quality of the channel is poor, data transmission from the channel will be stopped; further, channel switching can be performed: another idle channel is selected from the logical channel set to replace the channel.

[0073] Since the length of the monitoring period will affect the performance of data transmission: on the one hand, if the monitoring period is too long, it may cause interference with the authorized signal or waste some spectrum opportunities that may be accessed; on the other hand, if the monitoring period is too short, it will cause a large monitoring overhead; therefore, the present disclosure optimizes the monitoring period by analyzing the impact of the monitoring period on the perceived overhead, missed spectrum opportunities and interference with the authorized signal: the monitoring period can be determined based on the indicator parameters of each channel; wherein the indicator parameters of a channel include: the time proportion of idle spectrum opportunities wasted due to monitoring in the channel within a monitoring period, the average missed spectrum opportunities within a monitoring period, and the time proportion of interference with the authorized signal within a monitoring period. The specific analysis method will be introduced in detail later.

[0074] The analysis and optimization methods of the monitoring cycle mentioned in the above steps are described in detail as follows:

[0075] like represents the average time that channel i is busy in (t′, t′+t) when it is idle at the current time t′, that is, the average time that channel i interferes with the authorized user who appears again due to failure to monitor in time within t. Similarly, let It means that channel i is busy at the current time t′, and the average time that the channel is idle in (t′, t′+t), that is, the average time that channel i misses access opportunities at time t. According to the update theory and Laplace transform, the following formulas 1 and 2 can be obtained:

[0076]

[0077] in, represents the probability that the ith channel is busy. represents the monitoring period of the ith channel, and They represent the average spectrum loss opportunities and the time proportion of interference to authorized users of the i-th channel in a monitoring period, respectively, and the following formula 3 is obtained:

[0078]

[0079] From formula 3, we can see that and Both is a monotonically increasing function. Therefore, the average missed spectrum opportunity and the time ratio of interfering with authorized users increase with the increase of monitoring period. Usually, the terminals of cognitive users obey the "listen before transmission" principle, so when a channel is monitored, other channels must stop transmitting. Assuming that a total of K channels are monitored, the monitoring period vector of K channels is is the monitoring time of channel i, let SO i (T p ) indicates that the i-th channel is in a monitoring cycle The proportion of idle spectrum opportunity time wasted due to internal monitoring is obtained as follows:

[0080]

[0081] In order to improve spectrum utilization and reduce interference to authorized users, the missed spectrum opportunities, monitoring overhead and interference time are comprehensively considered, and the minimum monitoring cost is obtained by optimizing the monitoring period. In summary, the optimization equation of the channel monitoring period is shown in Formula 5:

[0082]

[0083] In formula 5, λ1 and λ2 are preset weight factors, which are set by the system. A larger λ1 can improve the spectrum utilization of the system, and a larger λ2 can reduce interference to the authorized signal. K is the number of monitored channels.

[0084] It can be seen from the above that the monitoring period can be determined based on the indicator parameters of each channel; among which, the indicator parameters of a channel include: the time proportion of idle spectrum opportunities wasted due to monitoring of the channel in a monitoring period, the average missed spectrum opportunities in a monitoring period, and the time proportion of interference with authorized signals in a monitoring period.

[0085] Furthermore, in the process of monitoring a channel, the length of time used to monitor the channel in a monitoring cycle may be optimized.

[0086] In fact, if the monitoring time is too long, it will lead to a large monitoring overhead; if the monitoring time is too short, it will affect the monitoring performance; therefore, it is necessary to optimize the monitoring time and compromise to achieve better monitoring performance with a smaller monitoring overhead.

[0087] Assume that K channels are monitored; the probability of monitoring the ith channel as busy during monitoring is Q, that is, the probability of monitoring the ith channel as non-idle during monitoring is Q b,i As shown in Formula 6:

[0088] Q b.i =u i Q d,i +(1-u i )Q f,i (Formula 6)

[0089] Therefore, the probability that all K channels are in non-idle state is Let r i represents the throughput of cognitive users transmitting data on the i-th channel. Then the optimization objective function is as follows:

[0090]

[0091]

[0092]

[0093]

[0094] in Avoid the total monitoring time exceeding the monitoring period. β Avoid the occurrence of cognitive users frequently searching for new idle channels. Γ i is to monitor the performance constraints and ensure the QoS of authorized users. i All are related to system requirements and are set by the system. and All about The increasing function, Q b,i right Monotonically increasing, so the optimization objective function is is monotonically decreasing and has nothing to do with the number of channels K. Therefore, the joint optimization problem can be divided into two independent optimization problems. First, Optimize, and then optimize K. First, satisfy each channel Γ i Under the premise of the requirement, the shorter the monitoring time, the better. Therefore, the optimal monitoring time for each sub-channel is As shown in the following formula 7:

[0095]

[0096] It's Q d,i After determining the optimal monitoring time of the sub-channel, the number of channels is optimized, that is, the optimal number of monitoring channels Kopt As shown in the following formula 8:

[0097]

[0098] From formula 8, we can see that under the constraints, when the channel conditions are the same, the optimal number of channels is only In this case, half of the monitoring period is used to monitor the channel to obtain the maximum average throughput, that is, the monitoring time is half of the monitoring period to obtain the maximum average throughput.

[0099] In fact, when a terminal uses multiple channels for data transmission at the same time, it is necessary to periodically monitor the multiple channels. If the number of channels is large, although the data transmission efficiency can be improved, it will also lead to an increase in monitoring overhead. Therefore, optimizing the number of channels used and calculating the optimal number of channels can compromise between having a certain data transmission efficiency and avoiding excessive monitoring overhead.

[0100] Step S240: re-determine the target channel based on the monitoring result.

[0101] In specific implementation, the terminal of the cognitive user periodically monitors each channel in use to ensure the communication quality. For a channel in use, the communication quality of the channel will be monitored in each monitoring cycle to determine whether the channel is suitable for continued data transmission; if the monitoring result shows that the communication quality of the channel is poor, data transmission from the channel will be stopped; further, channel switching can be performed: that is, another idle channel is selected from the logical channel set to replace the channel.

[0102] From the above, it can be seen that the channel monitoring method provided by the embodiment of the present disclosure includes: determining a logical channel set composed of channels that meet the access conditions; determining an idle channel from the logical channel set, determining a target channel from the idle channel, and transmitting data based on the target channel; monitoring the target channel based on a predetermined monitoring period to obtain a monitoring result, wherein the monitoring period is obtained based on indicator data of each channel in the target channel within one of the monitoring periods, and the indicator data includes: average missed spectrum opportunities, time proportion of idle spectrum opportunities wasted due to monitoring, and time proportion of interference with authorized signals; re-determining the target channel based on the monitoring result. Channel monitoring is performed through the monitoring period determined by the present disclosure, while taking into account monitoring overhead and access opportunities, thereby reducing the waste of access opportunities while reducing monitoring overhead.

[0103] Specifically, the monitoring period is optimized by integrating the indicator parameters of the time ratio of idle spectrum opportunities wasted due to channel monitoring, the average missed spectrum opportunities, and the time ratio of interference with authorized signals. This reduces the perception (monitoring) overhead during channel monitoring based on the monitoring period, while wasting as few possible access spectrum opportunities as possible, thereby improving data transmission performance.

[0104] It should be noted that the method of the embodiment of the present disclosure can be performed by a single device, such as a computer or a server. The method of the present embodiment can also be applied in a distributed scenario and completed by multiple devices cooperating with each other. In the case of such a distributed scenario, one of the multiple devices can only perform one or more steps in the method of the embodiment of the present disclosure, and the multiple devices will interact with each other to complete the described method.
