Description

Message sending method, resource allocation method and device

Technical field

The present invention relates to the field of communications technologies, and in particular, to a message sending method, a resource allocating method, and a device.

Background technique

With the continuous development of LTE (Long Term Evolution) communication technology, direct communication of D2D (Device-to-Device) has emerged. The D2D technology enables direct communication between the UE (User Equipment) on the data transmission resources (ie, carriers) provided by the base station without forwarding through the base station, which largely solves the problem of the existing spectrum. Problems such as excessive network load.

In the prior art, resource allocation for D2D device communication has two modes: Mode 1 and Mode 2. The following is a description of each mode: Mode 1 is a mode of centralized control allocation of resources. The D2D data transmission resource is scheduled by the base station or the relay node, and the UE directly transmits data and control information on the allocated resources. The centralized control resource allocation is mainly for the network coverage scenario. Mode 2 is a mode of competing resources reserved by the UE, and belongs to a distributed resource multiplexing method. The transmission resource is obtained from the resource pool by the UE as the transmitting end in a contention manner. In a scenario with network coverage, a resource pool is a whole block of resources that are separated by a base station, and all UEs compete for small blocks of resources in the entire resource. In the scenario where there is no network coverage, the resource pool is that the UE can obtain a predefined system bandwidth, and all UEs compete for resources under predefined resources. However, in the mode 2 competition-based resource allocation mode, since there is no coordination between the base station or the relay node, resource conflicts may occur between different UEs, and services with different priorities may also have resource competition conditions. A service with a high priority may not compete with the corresponding resource and cause the failure of information transmission.

With the development of D2D technology, V2X (Vehicle to Everything) technology has been successfully established as a major application of D2D technology. V2X is V2V (Vehicle to Vehicle), V2P (Vehicle to Pedestrian, vehicle to Pedestrian) and V2I (Vehicle to Internet, vehicle to network), as shown in Figure 1. In the V2X technology, the UE periodically sends a CAM (Cooperative Awareness Messages) message or a BSM (Basic Safety Message) message, and the CAM/BSM message packet is not considered in consideration of security overhead. The size is fixed, and the packet sizes of the two types of messages are shown in Table 1 and Table 2. However, based on security applications, V2X communication needs to consider PKI (Public Key Infrastructure). Typical security mechanisms include signature, digest, and certificate. The signature and digest are sent along with the CAM/BSM message. The certificate is sent every 1 s in the CAM message, but in the BSM. The message is sent every 500ms. Since the CAM/BSM message transmission is relatively frequent, adopting mode 1 will cause a large system overhead, and the probability of message collision using mode 2 is relatively large.

In order to reduce the system overhead and reduce the collision probability, in the prior art, the resource scheduling of the periodically transmitted message is a SPS (Semi-Persistent Scheduling) technology. In the SPS mode, the eNB (evolved NodeB) indicates the current scheduling information of the UE through the PDCCH (Physical Downlink Control Channel), and the UE identifies the semi-persistent scheduling, and saves the current The scheduling information is used to transmit or receive the service data on the same time-frequency resource indication every fixed period. By using semi-persistent scheduling transmission, the characteristics of periodic transmission and reception of message data packets can be fully utilized, and one-time authorization and periodic use can effectively save PDCCH resources used by the LTE system for scheduling indication.

The existing SPS technology requires that the size of the data packet sent is fixed, and the arrival period of the data packet is required to be fixed. In V2X, for the CAM/BSM message sent by the UE, the arrival period of the data packet is not fixed, and the existing SPS mechanism cannot be satisfied. When the message is to be sent, there may be no corresponding transmission resource, which is difficult to guarantee. The timeliness of message transmission, and when no message is sent, the allocated transmission resource is in an idle state, which causes a waste of transmission resources to a certain extent.

Summary of the invention

In order to improve the resource utilization, the embodiment of the invention provides a message sending method, a resource allocation method and a device. The technical solution is as follows:

In a first aspect, the embodiment of the present invention provides a message sending method, including: acquiring resource indication information according to a sending period of a current to-be-sent message, where the resource indication information is used to indicate a transmission resource that satisfies the sending period; Sending a message on the transmission resource indicated by the resource indication information.

For different sending periods, the corresponding message has a unique deterministic. Therefore, the method can send the sending period of the to-be-sent message to the base station, so that the base station can according to the one-to-one correspondence between the sending period and the data packet size, according to the one-to-one correspondence between the sending period and the data packet size. Different transmission periods and packet sizes are allocated different transmission resources, thereby reducing system overhead, reducing frequent scheduling of the base station, and avoiding the mismatch between the message and the transmission resource, and greatly improving the utilization of the transmission resource.

In a first possible implementation manner of the first aspect, the acquiring the resource indication information according to the sending period of the current to-be-sent message includes:

If the first resource is not configured, the first resource request message is sent to the base station, where the first transmission resource request message carries the sending period, and receives the first resource indication information, and the first resource indicated by the first resource indication information As a resource for sending the message, if the first transmission resource is configured, the first transmission resource is used as a resource for sending the message; wherein the first transmission resource is configured by the base station for the user equipment. Semi-static resources. The semi-static resource can be an SPS resource. In mode 1, the base station can perform resource allocation for the message according to the sending period of the message, and the resource allocation can match the sending period and the packet size, thereby improving resource utilization.

In conjunction with any of the foregoing possible implementation manners, in a second possible implementation manner of the foregoing aspect, before the obtaining the resource indication information according to the sending period of the current to-be-sent message, the method further includes:

Comparing the packet size of the message with the packet size of the last sent message; if the difference between the packet size of the message and the packet size of the last sent message is less than the first preset threshold And performing the step of acquiring the resource indication information according to the sending period of the current to-be-sent message; if the difference between the data packet size of the to-be-sent message and the data packet size of the last-sent message is greater than or equal to the first preset The threshold value is obtained according to the data packet size of the message.

On the basis of the foregoing second possible implementation manner, in a third possible implementation manner of the foregoing aspect, the acquiring the resource indication information according to the data packet size of the message includes: if the first transmission resource is configured, Sending a second resource allocation request to the base station, where the second resource allocation request carries the difference, and receives the second resource indication information, where the second resource indication information is used to indicate that the base station is the user equipment according to the difference Assigning a second resource; correspondingly, transmitting the message on the transmission resource indicated by the resource indication information includes: transmitting, on the second resource, a first part of the message, and transmitting, on the first transmission resource a second portion of the message; wherein the first portion is a portion of a data packet of the message that is changed relative to a data packet of the last time the message was sent, and the second portion is a packet of the message a portion other than the first portion. The foregoing embodiment can further improve the success of the message sending by applying the supplementary resource for the message to be sent to ensure the normal transmission of the message, and the supplementary resource of the application is a dynamic resource.

On the basis of the foregoing second possible implementation manner, in the fourth possible implementation manner of the foregoing aspect, the acquiring the resource indication information according to the data packet size of the message includes: if the first transmission resource is configured, The base station sends a third resource allocation request, where the third resource allocation request carries the data packet size of the message, and receives the third resource indication information, where the third resource indication information is used to indicate that the base station is configured according to the data packet size. The third resource assigned to the user device. The foregoing embodiment can further improve the success of the message sending by applying the supplementary resource for the message to be sent to ensure the normal transmission of the message, and the supplementary resource of the application is a dynamic resource.

With reference to the foregoing third or fourth possible implementation manner, in the fifth possible implementation manner of the foregoing aspect, the acquiring the resource indication information according to the data packet size of the current to-be-sent message includes: releasing the message when the periodic message is sent The resources requested. Through the release of supplementary resources, it can be improved The effect of the source reuse rate.

If the first transmission resource is not configured, the UE is required to request the base station to obtain the resource that can satisfy the sending period, and obtain the transmission resource by using different technical means in the configured and unconfigured scenarios to meet the requirement for sending the message. The integrity of the entire program is achieved.

In conjunction with any of the foregoing possible implementation manners, in a seventh possible implementation manner of the foregoing aspect, the method further includes: releasing the first transmission resource if the first transmission resource is configured and no message needs to be sent. If it is determined that the UE does not need to send a message later, the configured first transmission resource may be released, so that the first transmission resource can be recycled and reused, thereby greatly improving resource utilization.

In the scenario of mode 2, even if no base station participates in resource allocation, a certain transmission resource may be periodically occupied by the UE. In order to fully utilize the occupied resources, the difference between the packet size and the last sent message may be small. In the case of the use of occupied resources to complete the message, and if the difference is large, you need to listen to the resource pool to obtain more supplementary resources.

The following describes the specific embodiments of the embodiments of the present invention:

FIG. 4 is a flowchart of a method for sending a message according to an embodiment of the present invention. In this embodiment, only the scenario in which the current UE is in mode 1 is taken as an example. In this scenario, the user equipment may be allocated a transmission resource corresponding to the transmission period by using a different transmission period of the message. Referring to FIG. 4, the embodiment specifically includes:

401. If a message is to be sent on the UE, and the UE does not configure the first transmission resource, the UE sends a first resource request message to the base station, where the first transmission resource request message carries the sending period.

The first transmission resource is a SPS (Semi-Persistent Scheduling) resource configured by the base station for the UE, and if the UE is configured with the first transmission resource, the UE may periodically be at the same time-frequency resource location. Send or receive a message.

Table 1-4 shows that for different sending period messages, the packet size is different. Through the sending period, the packet size of the message can be determined, so that the message is allocated based on the sending period and the packet size. The resource is transmitted. Therefore, when the first resource request message is sent to the base station, the sending period of the message may be carried.

For example, referring to Table 3, if the transmission period is 400 ms, it can be known by querying Table 3 that the packet size of the message is 122 bytes. If the sending period is 800 ms, it can be known by querying Table 3 that the packet size of the message is 182 bytes.

402. The base station receives the first resource request message.

403. The base station determines, according to a sending period carried by the first resource request message, a data packet size of the message.

It should be noted that the sending period and the packet size have a one-to-one correspondence. Therefore, the packet size of the message can be uniquely determined by the sending period, thereby performing a subsequent allocation process.

404. The base station allocates, by the base station, the first resource that meets the sending period and the data size according to the sending period of the message and the data packet size.

For example, when the transmission period is 400 ms and the packet size of the message is 122 bytes, the UE is allocated a time-frequency resource capable of transmitting 122 bytes of data every 400 ms.

405. The base station sends the first resource indication information to the UE, where the first resource indication information is used to indicate that the first resource is satisfied.

406. The UE receives the first resource indication information, and uses the first resource indicated by the first resource indication information as a resource for sending the message.

407. The UE sends the message on the first resource indicated by the first resource information.

Of course, if the first transmission resource is configured, the UE may use the first transmission resource as a resource for sending a message, and send a message on the configured transmission resource. Further, if no message needs to be sent on the first transmission resource, the resource release message may be sent to the base station, so that the base station releases the transmission resource. For example, the transmission resource is recycled to the resource pool for other UEs to perform resource application.

The above embodiment can enable the base station to send a transmission period of the to-be-sent message to the base station in a scenario in which the semi-persistent scheduling resource is not configured, so that the base station can perform different transmission periods according to the one-to-one correspondence between the transmission period and the data packet size. The transmission resource is allocated differently from the data packet size, thereby reducing system overhead, reducing frequent scheduling of the base station, and avoiding the mismatch between the message and the transmission resource, and greatly improving the utilization of the transmission resource.

FIG. 5 is a flowchart of a message sending method according to an embodiment of the present invention. In this embodiment, the scenario in which the current UE is in mode 1 is still taken as an example. In this scenario, the current A comparison is made between the packet size of the sent message and the packet size of the last sent message to determine whether the previously configured first transmission resource can satisfy the current message transmission requirement. Referring to FIG. 5, the embodiment specifically includes:

501. The UE compares the packet size of the message with the packet size of the last sent message.

502. If the difference between the data packet size of the message and the data packet size of the last sent message is less than the first preset threshold, the UE performs the step of acquiring the resource indication information according to the sending period of the current to-be-sent message.

It should be noted that, when it is determined by comparison that the difference between the data packet size of the current message to be sent and the data packet size of the last time the message is sent is less than the first preset threshold, the packet size of the message may not be considered as being If there is a change, there are at least two things that can happen:

The first case: if the UE has configured the first transmission resource, the first transmission resource used for the last message transmission is also sufficient to meet the transmission requirement of the current message, and the message may be directly sent on the first transmission resource.

The second case: if the UE does not configure the first transmission resource, the resource indication information may be acquired according to steps 401-407 in the foregoing embodiment shown in FIG. 4, thereby acquiring a transmission resource for sending a message, where For details, refer to steps 401-407, and details are not described herein.

503. If the difference between the data packet size of the to-be-sent message and the data packet size of the last sent message is greater than or equal to the first preset threshold, if the first transmission resource is configured, send the second resource allocation to the base station. The request, the second resource allocation request carries the difference.

The first preset threshold may be set by the system according to the size of the optional data part of the message (for example, for the CAM message, refer to the size of the optional part in Table 1), for example, the first preset threshold. The value ranges from 0 to 11 bytes.

It should be noted that, when it is determined by comparison that the difference between the data packet size of the current message to be sent and the data packet size of the last time the message is sent is smaller than the first preset threshold, the packet size of the message may be considered to have occurred. If the configured first transmission resource cannot meet the sending requirement of the current message in the scenario that the first transmission resource is configured, the node needs to request more transmission resources from the base station. The requested transmission resource may be a DS (Dynamic Scheduling) resource.

For example, still see the first row and the fourth row in Table 3. In the first row, the message size of the message "High-frequency part with signature and digest" is 122 bytes, and the message in the fourth line is "signed and The high-frequency part of the digest + full certificate has a packet size of 239. Therefore, when the message to be sent is the message "high-frequency part with signature and digest + full certificate", if the last message was sent with "signature and When the high frequency portion of the digest is greater than the first preset threshold 10, it is determined that the packet size has changed, and the transmission resource used to transmit the message in the first row is insufficient to transmit the current message. Since the "Full Certificate" section can be sent separately from the "High-frequency part with signature and digest" section, a portion of the transmission resource can be requested separately for the "Full Certificate" section, and the "High-frequency part with signature and summary" can Send using the configured first transmission resource.

504. The base station receives the second resource allocation request.

505. The base station allocates, according to the difference carried by the second resource allocation request, the second resource that meets the difference.

Since the difference is a relatively small value, if the UE performs a resource allocation request based on the difference, the success rate is higher, which also reduces the time consuming of the resource allocation process.

506. The base station sends the second resource indication information to the UE, where the second resource indication information is used to indicate that the base station allocates the second resource to the user equipment according to the difference.

507. The UE receives the second resource indication information.

508. The UE sends a first part of the message on the second resource, and sends a second part of the message on the first transmission resource.

The first part is a part of the data packet of the message that changes with respect to the data packet of the last time the message was sent, and the second part is a part of the data packet of the message except the first part.

509. After the UE sends the first part of the message on the second resource, release the second resource.

The step 509 is an optional step. After the UE performs the sending, the UE may send a release request message to the base station, so that the base station releases the second resource to avoid excessive occupation of resources.

It should be noted that the above process of applying for the second resource for the first part can be applied to the first part. The sub-division can be separated from the second part, and regardless of whether the first part and the second part can be divided, the message can be reconfigured to meet the transmission requirement of the message. Correspondingly, the above steps 503 to 508 may be replaced by the following steps: if the first transmission resource has been configured, a third resource allocation request is sent to the base station, and the third resource allocation request carries the data packet size of the message. The base station receives the third resource allocation request, and allocates a third resource that meets the data packet size to the UE according to the data packet carried by the third resource allocation request. The base station sends the third resource indication information to the UE, where the third resource indication information is used to indicate the third resource allocated by the base station to the user equipment according to the data packet size. The UE receives the third resource indication information, and sends the message on the third resource. Further, the process may further include the UE releasing the third resource after sending the message on the third resource.

The foregoing embodiment can enable the base station to dynamically allocate the optimal amount of resources to the UE by using the resource for transmitting the message as a whole or part of the message to the base station in the scenario that the semi-persistent scheduling resource is configured but cannot meet the sending requirement, thereby reducing the resource. The system overhead reduces the frequent scheduling of the base station, and avoids the imbalance between the message and the transmission resource, greatly improves the utilization of the transmission resource, and can selectively apply for the resource according to whether the message is separable or not. It can meet the transmission requirements of different message components on the UE side, and further avoids waste of resources.

Further, for a scenario in which the UE is in mode 2, the UE may also acquire different transmission resources according to different packet sizes. Although the UE is in the mode 2 scenario and is not controlled by the base station, the UE may periodically occupy a certain transmission resource for message transmission, and the occupied transmission resource may be referred to as a second transmission resource, and the second transmission resource may be monitored by the UE by listening to the resource. The pool is obtained without being configured by the base station.

In the scenario that the UE has occupied the second transmission resource, if the UE has a message to send, the packet size of the message to be sent and the packet size of the last sent message may be compared, if the packet size of the message and the last time The difference between the packet sizes of the sent messages is less than the second preset threshold, and if the second transmission resource is already occupied, the second transmission resource is used as the resource for transmitting the message.

If it is determined by comparison that the packet size has not changed, the second transmission resource may be used as the transmission. A resource for sending a message, and transmitting a message on the second transmission resource. And if the difference between the packet size of the message and the packet size of the last sent message is greater than or equal to a second preset threshold, the resource pool may be monitored according to the packet size or the difference, from the The fourth resource for sending the message is obtained in the resource pool. The fourth resource obtained can have the following two situations:

In the first case, the fourth resource is the fourth resource of the first target size. The first target size is the difference between the packet size of the message and the packet size of the last transmitted message.

In this case, since the UE has occupied a certain second transmission resource, the transmission resource corresponding to the difference capacity can be monitored for the message based on the capacity of the second transmission resource, thereby being able to satisfy the The overall delivery requirement of the message.

In the second case, the fourth resource is the fourth resource of the second target size. The second target size is a packet size of the message.

In this case, although the UE has already occupied a certain second transmission resource, in order to ensure the integrity of the message transmission, the second transmission resource that has already been occupied may be released, and the data of the message is monitored for the message. The packet size corresponds to the capacity of the transmission resource, so that the overall transmission requirement of the message can be satisfied. Certainly, whether the second transmission resource is released may be performed according to the system setting, which is not specifically limited in this embodiment of the present invention. If the release is performed, other UEs can also use the transmission resource to improve the utilization of resources to some extent.

In the foregoing embodiment, when the UE has occupied a certain transmission resource, the resource pool is monitored by itself to obtain the supplementary resource, so that the message is sent, so that the UE can trigger the hybrid resource allocation according to the packet size, which not only reduces the system overhead. Moreover, the utilization rate of the transmission resources is greatly improved, and the probability of resource collision is further reduced by releasing the resources after use.

The foregoing process is only introduced based on a scenario in which the UE has occupied the second transmission resource. If the UE does not occupy the second transmission resource, the packet size may not be compared, but the resource pool is directly monitored according to the packet size of the message. To obtain a fourth resource that can satisfy the packet size.

The fourth resource that is obtained by the UE may be periodically occupied by the UE to meet the requirement of sending a message, or the resource may be released after being occupied once to improve resource utilization.

Further, in order to avoid resource conflicts with other UEs, for any of the foregoing embodiments for monitoring the resource pool, the UE needs to send a broadcast message when occupying any of the fourth resources obtained by the monitoring. The broadcast message is used to notify the occupancy of the fourth resource and the sending period of the message. When other UEs receive the broadcast message, they will avoid resource conflicts and send messages on other resources or on other periods of the resource.

In order to avoid the impact on the normal transmission of the message and improve the transmission success rate, for any of the foregoing embodiments for monitoring the resource pool, when a resource conflict occurs on the fourth resource that is already occupied by the user, the resource conflict occurs. Resources, re-perceive resource pool monitoring.

Of course, in order to further improve the resource utilization, for any of the foregoing embodiments for monitoring the resource pool, when there is no message to be sent on any of the fourth resources obtained by the interception, the occupied fourth resource is released.

In the above embodiment, when the UE does not occupy any transmission resources, the resource pool is monitored by itself to obtain supplementary resources, thereby implementing message transmission, so that the UE can obtain transmission resources according to the data packet size, which not only reduces system overhead, but also greatly improves The utilization of transmission resources is further reduced by the release of resources after use, which further reduces the probability of resource collisions.

For the foregoing embodiment, the message is sent in different scenarios according to the one-to-one correspondence between the sending period and the packet size, and the packet size is directly queried through the sending period, and vice versa, by the packet size. The classification may also determine the transmission period of the message, thereby further performing resource allocation based on the transmission period of the message. FIG. 6 is a flowchart of a message sending method according to an embodiment of the present invention. In this embodiment, the data packet can be divided into two categories: a large data packet and a small data packet according to the size thereof, and are respectively represented by the first type data packet and the second type data packet, and for the two data packets, The specific message sending process can be the same. Therefore, for the first type of data packets, examples are as follows:

601. The UE acquires a data packet category of the message according to a data packet size of the current to-be-sent message.

Wherein, when obtaining the category, the following process may be included: the data packet of the current message to be sent is large. Compared with the preset threshold, when the packet size is greater than or equal to the preset threshold, it may be determined as the first type of data packet, and when the data packet is less than the preset threshold, the small data packet may be determined as the second Class data package.

For example, if the preset threshold can be set to 200, then still refer to Table 3. When the packet size is 182, the packet type of the message can be determined as a second type of data packet, that is, a small data packet, and when When the packet size is 299, the packet type of the message can be determined as the first type of data packet, that is, the large data packet.

602. When the transmission resource that matches the data packet category is not configured, the UE sends a fourth resource allocation request to the base station, where the fourth resource allocation request carries category indication information, where the category indication information is used to indicate the data packet category.

The category indication information may be 1 bit dynamic instruction. For example, for the first type of data packet, the category indication information may be 0. For the second type of data packet, the category indication information may be 1. The category indication information may be located at any reserved location of the resource allocation request, and is configured by the system, which is not specifically limited in this embodiment of the present invention.

It should be noted that the embodiment of the present invention is only described by taking the transmission resource that the UE does not match the packet type as an example. In other embodiments, according to the difference of the judgment result, that is, if the UE is configured and configured The transmission resource matched by the packet class is sent on the configured transmission resource.

603. The base station allocates a fifth resource to the UE according to the packet type, where a data transmission capacity of the fifth resource meets a maximum possible value of the data packet category, and a sending period of the fifth resource meets the packet type. The greatest common divisor.

The base station can maintain the correspondence between the packet type and the maximum possible value of the data packet and the greatest common divisor of the transmission period, which is not specifically limited in this embodiment of the present invention. In this embodiment, the data packet is divided into two categories. In fact, the data packet can be further divided into two or more categories, and the specific allocation manner is the same as the foregoing classification manner, and can be classified according to the data packet size. This is not to be introduced.

For the packet type determining method of the embodiment, the data included in the classified category The range of the packet is large. Therefore, the base station can obtain the maximum possible value of the data packet matching the category and the greatest common divisor of the transmission period according to the category, so as to satisfy the transmission requirement.

For example, in Table 4, for a message with a packet size of 172 bytes, according to a preset threshold of 200 bytes, it can be determined as a second type of data packet, and the base station determines that the message is a second type of data packet.
