Description

Method for allocating communication resources of millimeter wave phased array antenna on demand

technical field

The invention relates to a resource on-demand allocation method suitable for communication based on a millimeter wave phased array antenna.

Background technique

Millimeter-wave phased array antennas have become the main antenna for many radar, satellite applications or wireless communications due to their powerful functions, flexible working methods, and computer-controlled inertial beam scanning. Phased array is short for "Phase Controlled Array". The phased array antenna is formed by arranging many radiating elements, and the feeding phase of each element is an array flexibly controlled by a computer. According to the basic theory of phased array antennas, several antennas are arranged in space and connected to each other to generate a directional pattern. This structure of multiple radiating elements is called an antenna array, or simply an array. Millimeter wave phased array antennas have the advantages of narrow beam, fast scanning speed, and high gain, and can provide high data rate, long-distance, and signal-concealed networking communication. The directivity of the phased array antenna enables the network to use space division multiplexing to improve the transmission capacity. At the same time, the higher directional gain can increase the communication distance between nodes, thereby reducing the number of hops for node message forwarding; The waste of channel resources caused by contention and collision can guarantee the deterministic bandwidth and delay requirements between nodes. The existing technical solutions focus on the allocation of time slot resources for self-organizing networks designed for omnidirectional antennas, and do not consider the allocation of resources such as space and frequency. The existing time slot allocation methods all have their own limitations, and cannot take into account various performance requirements such as high efficiency, fairness, flexibility, and multi-priority guarantee in the selection of communication resources. The time resource refers to the transmission timing allocated for a certain node to access the channel for data transmission. Spatial resources refer to the space of the transmit antenna beams allocated for data transmission on a node's access channel. The frequency resource refers to the communication frequency allocated for a certain node to access the channel for data transmission. Different spatial positional relationships between network nodes determine different network topologies or link relationships between nodes. It is not only necessary to select the object and antenna for a single node to send data, but also to prevent interference caused by multiple nodes pointing to the same space at the same time to send data. The traditional wireless ad hoc network communication system is usually designed based on the omnidirectional antenna in the microwave frequency band. Every node within the coverage area of the antenna signal can receive the signal. The problem of communication resource allocation is relatively simple. It mainly allocates time slot resources. It involves resources such as space and frequency.

In the wireless communication network of the millimeter wave phased array antenna, the communication resources include three types of channel resources, such as time, space and frequency. In order to prevent communication failure caused by interference caused by multiple nodes sending data to the same node at the same time, the channel access mode of TDMA technology is usually used. As shown in FIG. 2 , the TDMA technology divides the communication time into multiple epochs, each epoch is divided into multiple time frames, and each time frame is further divided into multiple time slots. Each network node uses the control time slot arranged in the design to interact with the network topology in real time, and the node broadcasts the new time slot table to the neighbor nodes according to the topology information, and each neighbor node is in the correct time slot according to the time slot allocation table. Establish a link. Data exchange is performed between nodes through the communication time slots allocated by the time slot allocation table. During the normal operation of the network, each node calculates the working time slot allocation table. After the time slot allocation is performed, the allocation table is distributed to each neighbor node in the network, and then each node is allocated according to the latest time slot in the period of the control time slot. Table work, and periodic information sharing between nodes. The time slot allocated by a node is the opportunity when the node can access the channel to send data, and the length of the time slot determines the data capacity or data rate that can be sent.

Due to changes in the communication resource requirements of some nodes, it may happen that the allocated communication resources cannot meet the usage requirements. The main factors include: First, the demand for originating services changes. The originating services of nodes are mainly affected by applications. The communication objects and the amount of data sent and received are different for different applications, resulting in corresponding changes in time, space and frequency resource requirements; The location relationship changes, resulting in changes in the network topology or connection relationship. The nodes that originally have links may need to be relayed by other nodes, and the spatial multiplexing conditions may also change. A link must give up part of the resource occupation; three It is the change of member nodes. During the network operation, if a node exits or a new node joins, it is necessary to re-allocate resources. When the original occupied resources of the node do not match the usage requirements, the data packets will wait in the sending queue, or be discarded due to the sending timeout, which affects the communication delay, network efficiency and task achievement. On the other hand, if there is any demand mismatch, the resource allocation response will be carried out, which will bring frequent network parameter changes, which may cause important data packets of some nodes to be unable to be sent quickly and effectively, which is not conducive to the stable operation of the network. Therefore, it is necessary to judge whether or not to reallocate communication resources according to the degree of node demand change.

The main technical solutions of the existing time slot resource allocation are as follows:

Fixed time slot allocation method: Usually according to the principle of uniform resource allocation, time slot resources are pre-allocated to all nodes in the network before network operation, each node is allocated the same time slot block, and the allocation result remains unchanged during network operation . Each node obtains the right to use the channel according to the obtained time slot timing, and sends data when the time slot starts, and other nodes can only receive data. This method is simple to operate, but has poor adaptability. When the service requirements of nodes change frequently, the transmission delay of high-traffic nodes will increase and a large number of packets will be lost, while the time slot utilization of low-traffic nodes will be very low.

Random competition time slot allocation method: divide time resources into frames, each frame is divided into several time slots, network nodes compete for these time slots at the same time for data transmission, if multiple nodes collide, wait until the next time slot Continue to contend for time slots. This method can realize the dynamic allocation of time slot resources. Multiple nodes cannot perceive the resource requirements of other nodes in advance, and they will not distinguish the priority difference between nodes and services. When the network load is heavy and the competition is fierce, the probability of time slot competition conflict is high. The allocation efficiency will be very low.

Dynamic time slot allocation method: In the traditional dynamic time slot allocation method, the time slots in each time frame are divided into fixed allocation sections and competitive allocation sections, and each node obtains at least one time slot in the fixed allocation section to ensure basic data transmission. need. During network operation, nodes compete for idle time slots in the contention allocation segment according to data transmission requirements to meet bursty service transmission requirements. This method can maintain a relatively stable network throughput, but the nodes competing for time slots have a long convergence time and have poor multi-priority guarantee capability.

SUMMARY OF THE INVENTION

The purpose of the present invention is to provide a millimeter wave with better high-priority guarantee capability, better network throughput capability, better fairness, and balance between stability and adaptability, aiming at the shortcomings of the prior art. The on-demand allocation method of phased array antenna communication resources to achieve the multi-dimensional optimization goals of high efficiency, invulnerability, fairness, and multi-priority guarantee of the whole network communication resources.

The object of the present invention is achieved through the following technical solutions: a method for allocating communication resources of a millimeter-wave phased array antenna on demand, characterized in that it includes the following steps: in the wireless communication network of the millimeter-wave phased array antenna, constructing The resource allocation module, the queue buffer module, the resource demand interaction unit and the channel resource control module are connected around the resource occupancy allocation unit, wherein the queue buffer module sends the queue buffer parameters to the resource occupancy allocation module, and the resource occupancy allocation unit obtains the service message queue Cache parameter information, according to the priority message ratio of each queue, as a weight coefficient to perform a weighted average, calculate the comprehensive priority of the node, and complete the resource demand statistics; the resource demand interaction unit will calculate this platform when each control time slot arrives. The obtained capacity requirement on the link is carried out in the control message to complete the resource requirement interaction with the resource occupation allocation unit; the resource occupation allocation unit uses the resource requirement information to calculate the link set and antenna of all resources to be allocated according to the neighbor node information. Point to the difference between the capacity requirements of each link, and according to the neighbor resource requirement difference information obtained from the resource demand interaction unit, decide whether to re-allocate resources, and collect and store the available resources for resource occupation and calculation in the allocatable communication resource unit; resource occupation; The allocation unit uses the available frequency set as the link to allocate frequencies, selects and allocates time slots, frequency resources and communication peers, compares the demand level difference of the nodes by the time slot allocation factor, and triggers a new resource allocation when the demand level changes to a certain extent, Using the time slot allocation table and the identification number of the communication peer node, specify the beam pointing parameter for the time slot as the communication peer position, and allocate the time slot according to the order relationship of the members of both sides of the link and the time slot allocation factor until all the time slots are allocated. , and then renumber the time slot resources in each allocation cycle, in the way of alternately allocating resources under the same demand conditions, taking advantage of the set of allocatable time slots and directional communication to calculate the time slot resources for spatial multiplexing, and the time in the network Three types of resources, space resources and frequency resources are allocated dynamically on demand.

Compared with the prior art, the present invention has the following beneficial effects:

It has better high-priority guarantee capability: the present invention performs weighted average as a weight coefficient according to the priority message ratio of each queue, and calculates the comprehensive priority of the node. When the time slot allocation factors of nodes are the same, when the time slot resources cannot meet the demand, the nodes with higher priority obtain more time slot resources, thus ensuring that nodes with more high priority services can quickly send service messages. go out. Therefore, compared with the prior art, the present invention has better priority guarantee capability.

It has better network throughput: the present invention adopts a set of assignable time slots, utilizes the advantage of directional communication, and calculates the time slot resources of spatial multiplexing, so that the number of time slot resources that can be allocated to nodes for use is greatly increased. Make full use of the directional narrow beam communication characteristics of the millimeter wave phased array antenna, and dynamically allocate the three types of time resources, space resources and frequency resources in the network on demand. Compared with fixed resource allocation, it avoids resource idle caused by low traffic of some nodes, or excessively long transmission waiting or data loss caused by sudden high traffic of some nodes, improves the utilization rate of communication resources, and makes the network more efficient. Good throughput.

Better fairness: The present invention assumes that each node has the same resource requirements when the network is initially started. During the operation, in order to prevent uneven distribution of node resources in the network, a fair and equal distribution method is used to allocate resources. In each allocation cycle, time-slot resources are renumbered, and resources are allocated alternately under the same demand conditions, so as to ensure the fairness of resource allocation and avoid the unfair situation of resources of nodes with the same demand, especially the nodes that first access the network and those who are later Unequal distribution of network access node resources solves the problem that some nodes cannot obtain resources for normal communication due to preferentially occupying too many resources in the prior art.

Taking into account both stability and adaptability: The present invention adopts the time slot allocation factor method to compare the demand level difference of nodes. Only when the demand level difference changes to a certain extent, will a new resource allocation be triggered, which can resist the resource allocation disturbance caused by the small dynamics of the network. , to ensure the stable operation of the network. At the same time, it has strong dynamic adaptability. When the resource demand changes due to changes in network nodes, changes in location relationships, and changes in originating service requirements, the change in demand gradient will quickly trigger the reallocation of resources. Therefore, compared with the prior art, the present invention better takes into account the stability of the network operation and the adaptability to dynamic changes.

The invention automatically calculates new resource allocation requirements on the basis of real-time evaluation of the resource demand information of the node in each node, according to local time, frequency, space and other communication resource occupancy conditions, and negotiates new resource allocation requirements with neighboring nodes in a distributed manner. Resource allocation requirements, complete new resource occupancy confirmation, in order to achieve multi-dimensional optimization goals of network-wide communication resources in terms of efficiency, invulnerability, fairness, and multi-priority assurance.

The invention is suitable for resource on-demand allocation based on millimeter wave phased array antenna communication.

Detailed ways

See Figure 1. According to the present invention, the resource allocation resource demand statistics based on millimeter wave phased array antenna communication are realized according to the following steps: the resource occupation allocation unit obtains the service message queue buffer parameter information. The queue cache parameter information includes the sending object, message volume and priority of each queue. According to the priority of each cache queue, the resource occupancy allocation unit uses the ratio of each priority message as a weight coefficient to perform a weighted average, evaluates the comprehensive priority PR of the node, and evaluates the link capacity requirement of each cache queue according to the queue cache parameter information , using the received control message, calculate whether there is a new link with the neighbor node, evaluate the frequency demand FR and beam pointing demand DR of the node, and the link capacity demand is the time when the node in the queue sends to the link The number of slots required by TR is indicated.

Resource demand interaction: When each control time slot arrives, the resource demand interaction unit will carry out the capacity demand on the link calculated by the platform in the control message. The neighbor node resource demand interaction unit that receives the node control message sends the parameters to the resource occupation allocation unit, and the resource occupation allocation unit records the capacity demand of the node.

Resource occupancy calculation: The resource occupancy allocation unit calculates the link set and antenna orientation of all resources to be allocated according to the information of the neighbor nodes; the resource allocation unit calculates the capacity released by the received communication object according to the newly sent capacity requirement TR1 on a link and the received capacity. Demand TR2, calculate the capacity demand level difference between the two parties, so as to determine the time slot allocation factor, and sort each node according to the time slot allocation factor from large to small. When the time slot allocation factor is the same, the node with higher priority is ranked first; resource allocation The unit calculates the available frequency set according to all available frequency sets and the frequencies occupied by the allocated links in each time slot; the resource allocation unit calculates a certain chain according to the basic time slots that can be used for allocation and the time slots that can be spatially multiplexed. All communication time slots to be allocated on the road are numbered from front to back.

Resource occupancy allocation: The resource occupancy allocation unit allocates time slots according to the order relationship of the members of both sides of the link and the time slot allocation factor. The nodes in the front of the order allocate time slots first, and the larger the time slot allocation factor, the more time slots are allocated until all the time slots are allocated; the resource occupation allocation unit allocates frequencies for the links according to the available frequency set; The slot allocation table, and the ID of the communication peer node, specify the beam pointing parameter for the time slot as the location of the communication peer.

Resource occupation confirmation: The resource occupation allocation unit sends the resource allocation result to the resource demand interaction unit, and the resource demand interaction unit sends the allocation result to the neighbor node. After the neighbor node receives the resource allocation result, the resource occupation confirmation unit and the local new resource The allocation results are compared, and the conflicting resource is replied to the neighbor node, and the neighbor node deletes the conflicting resource after receiving the conflicting resource information.

Queue cache parameters mainly include the sending object, message volume and priority of each queue. The resource occupancy allocation unit evaluates the comprehensive priority PR, queue capacity requirement TR, frequency requirement FR and beam pointing requirement DR of the node, and delivers the node's requirement to the resource requirement interaction unit and sends it to the neighbor node. The resource occupancy allocation unit uses the resource demand information to calculate the set of links to be allocated and the direction of the antenna. For each link, the resource occupancy allocation unit calculates the capacity demand level difference, and according to the neighbor resource demand level difference information obtained from the resource demand interaction unit, decides whether to Re-allocate resources; the resource occupancy allocation unit calculates the available resource set and stores it in the allocatable communication resource unit, and selects and allocates time slots, frequency resources and communication peers. The resource occupancy allocation unit delivers the allocation result to the resource occupancy interaction unit, so as to send it to the neighbor for confirmation of the resource allocation result. Finally, the resource occupation allocation set is updated, and the new resource occupation allocation result is sent to the channel access unit.

Referring to FIG. 2, in the processing flow of the resource allocation unit of the millimeter wave phased array antenna communication.

Step 500, the resource occupation allocation unit evaluates the comprehensive priority PR of the current node of each queue according to the priority of the cache queue, and performs a weighted average according to the weighting system of each priority to obtain the comprehensive priority PR of the current node, and then goes to step 501. Calculate each queue capacity requirement.

Step 501, the resource occupancy allocation unit evaluates the capacity requirement TR of each queue according to the sending object and the amount of messages buffered in the queue, and obtains the message sending requirement=the amount of messages that need to be sent to the link in the message queue/(communication rate*A*T _slot ), where A is the number of time slots assigned to the node to send on the link, and T _slot is the length of each time slot. When the message sending requirement is less than 0.3, the capacity requirement is Level 1; when the message sending requirement is less than 0.3-0.5, the capacity requirement is Level 2; when the message sending requirement is less than 0.5-0.7, the capacity requirement is Level 3; when the message sending requirement is less than 0.5-0.7, the capacity requirement is Level 3; When it is greater than 0.7, the capacity requirement is level 4. Then go to step 502 to calculate frequency requirements and beam pointing requirements.

Step 502, the resource occupation allocation unit evaluates the frequency demand FR of the node and the transmission capacity demand of the beam pointing demand DR according to the exchanged control messages, and calculates whether there is a new link with the neighbor node, if it is a new node, then The frequency allocation demand FR is increased, and the beam pointing demand DR for the newly added node is increased, and then the process goes to step 503 to calculate the link set to be allocated.

In step 503, the resource occupation and allocation unit calculates the set of links to be allocated according to the neighbor node information, traverses the set of links to be allocated, and then proceeds to step 504 to determine whether the links to be allocated are empty.

Step 504, the resource occupation allocation unit judges whether the link to be allocated is empty according to the traversal state of the link to be allocated, if the link to be allocated is empty, the resource allocation ends; otherwise, go to step 505 to calculate the capacity requirements of both sides of the link difference.

Step 505, the resource occupation allocation unit calculates the capacity requirement level difference between the two parties according to the capacity demand TR1 recently sent out on a certain link and the capacity demand TR2 issued by the received communication object, and the capacity demand level difference=|TR2-TR1| Go to step 506 to calculate the time slot allocation factor X of the link.

Step 506 , the resource occupation and allocation unit calculates the time slot allocation factor X according to the difference in capacity demand;

Step 507, the resource occupancy allocation unit judges whether it is greater than 1 according to the value of the time slot allocation factor X, if the value of the time slot allocation factor X is greater than 1, then go to step 508 to calculate the available resource set; otherwise go to step 404, for the next link for resource allocation.

Step 508, the resource allocation unit calculates the set of available frequencies according to all available frequency sets and the frequencies occupied by the allocated links in each time slot; the resource allocation unit calculates the set of available frequencies according to the basic time slots available for allocation and the time slots that can be spatially multiplexed Slots, calculate all the communication time slots to be allocated on a certain link, and number them from front to back. Then go to step 509 to sort both sides of the link.

Step 509, the resource allocation unit sorts the nodes from large to small according to the time slot allocation factors of the nodes. When the time slot allocation factors are the same, the nodes with higher priority are ranked first, and then go to step 510 to select the first time slot allocation. For members with less needs.

In step 510, the resource allocation unit sorts the time slot resources, and selects the first time slot to be allocated to the nodes that are ranked later, that is, the members with less demand. Then go to step 511 to select the first X time slots in the remaining time slots to be allocated to the members with more demands.

Step 511 , the resource allocation unit allocates the top X time slots in the remaining time slots to the nodes that are in the top order, that is, the members with more demands. Then go to step 512 to select the frequency to assign to the link.

Step 512, the resource allocation unit selects a frequency from the set of available frequencies to allocate to the link if it determines that a new frequency needs to be allocated according to the frequency requirement. Then go to step 513 to select the position corresponding to the ID of the communication peer node as the beam pointing parameter.

Step 513 , the resource allocation unit uses the ID of the communication peer node as the communication destination node according to the beam pointing requirement DR, so as to select the position corresponding to the ID as the beam pointing parameter during communication. Then go to step 514 to determine whether the remaining time slots are >0.

Step 514, the resource allocation unit judges whether the remaining time slots are > 0 according to the set of remaining time slots, and if the remaining time slots are > 0, the resource allocation ends; otherwise, go to step 510 to continue the remaining time slot allocation.

See Figure 3. The figure shows the link A-B formed by the wireless network node function based on millimeter wave phased array antenna communication. Each node of the link A-B mainly includes five functional modules: a queue buffer module, a resource sub-module, a channel access module and a wireless transmission module connected in parallel by the application module. Different application programs of the application module generate and send messages and process and receive messages; The queue cache module receives the sending messages generated by the application program and buffers them in the queue for sending, and establishes cache queues for different communication objects respectively; the resource allocation module includes an assignable communication resource unit, a resource demand interaction unit and a resource occupation allocation unit. The resource allocation module selects resources from the allocatable communication resource units for allocation according to the node resource requirements, and exchanges control messages of resource allocation with other nodes through the resource demand interaction unit; the channel access module selects time slots according to the channel access control protocol, Antenna and direction selection and frequency selection, send the selected time slot, antenna, direction and frequency to the wireless transmission module through the access channel on the communication resource; the wireless transmission module realizes the physical layer transmission and reception of the message through wireless transmission and wireless reception respectively.

See Figure 4. A wireless network based on mmWave phased array antenna communication is a self-organizing network without infrastructure support. The network nodes are all composed of air mobile platforms, each platform is equipped with multiple directional antennas, and a wireless communication network is dynamically established according to needs. When some nodes fail or links are interrupted, other nodes automatically reconfigure the network to maintain normal communication. When the node D fails or the link D-E is interrupted, the nodes A, B, E, and F can still maintain normal communication. When nodes communicate with each other, signal radiation is limited within the beam range, and it is very difficult to intercept communication signals and locate nodes. Therefore, the communication network has strong survivability and concealment, and is very suitable for safe and reliable communication between air mobile platforms that may enter the threat environment.

See Figure 5. The time slot types include control time slots and communication time slots, messages such as control time slot interaction location and network management, and communication time slot interaction service data messages. Due to the radiation characteristics of narrow beams of directional antennas in millimeter-wave phased array antenna communication wireless networks, as long as the antenna beams do not interfere with each other between multiple communication node pairs, data can be sent and received in the same time slot, thereby improving the throughput of the entire network. and utilization of time slot resources.
