Description

Resource scheduling method and resource scheduling device for vehicle communication

This application claims priority to Chinese Patent Application No. 201610322378.2, entitled "Resource Scheduling Method for Vehicle Communication and Resource Dispatching Device", filed on May 13, 2016, the entire contents of which are hereby incorporated by reference. Combined in this application.

Technical field

The present invention relates to the field of communications technologies, and in particular, to a resource scheduling method for vehicle communication and a resource scheduling device for vehicle communication.

Background technique

V2X (Vehicle to X, vehicle-to-target communication) is a project approved by 3GPP RAN#68, and mainly studies vehicle data transmission scheme based on 3GPP communication protocol. V2X includes V2V (Vehicle to Vehicle), V2P (Vehicle to Pedestrian), V2I (Vehicle to Infrastructure), and so on. In principle, V2V communication can realize V2V message transmission through Uu interface (interface between user equipment and base station), PC5 interface (interface between user equipment and user equipment) or Uu interface and PC5 interface. The scheme for implementing V2V message transmission through the Uu interface is as shown in FIG. 1. The source vehicle 102 (ie, the V2V message sending end) passes through an E-UTRAN (Evolved Universal Terrestrial Radio Access Network). The target vehicle (such as vehicle 104, vehicle 106, and vehicle 108 shown in FIG. 1) transmits a V2V message.

The vehicle terminal (Vehicle UE, hereinafter collectively referred to as V-UE) will continuously send V2V messages to the surrounding vehicle terminals during the mobile process, and the V2V messages may be periodic or non-periodic. The definition of the periodic V2V message includes the following three types: CAM (Cooperative Awareness Message), DEMN (Decentralized Environmental Notification Message), and BSM (Basic Safety Message). Among them, DEMN and BSM The type of V2V message is characterized by a variable size but a fixed period, while the CAM type V2V message is characterized by size and period. All are variable.

At present, the LTE (Long Term Evolution) system supports the SPS (Semi-Persistent Scheduling) mechanism for the services that are periodically transmitted, such as VoIP (Voice over Internet Protocol). The resource allocation mechanism periodically allocates radio resources to certain UEs, thereby saving signaling overhead. As shown in Figure 2, the SPS mechanism is mainly designed with VoIP services with small data packets and variable size but fixed periods. For periodic services such as VoIP, the moment when the service occurs and the required radio resources are pre-estimated by the eNB (base station), and the eNB re-allocates the radio resources based on SPS reconfiguration in any subframe.

However, for vehicle communication messages, the size and/or period of the message may change at any time as the V-UE changes (eg, speed, location, etc.), relying solely on the eNB's pre-estimation for SPS configuration/ Reconfiguration, which may require a certain delay to observe this change, may have a large impact on certain delay-sensitive emergency services (such as V2V messages such as failure/runaway). In short, if the V2V message is transmitted and reused by the existing SPS mechanism, only the DEMN and BSM types can be supported, and the CAM type V2V message cannot be well supported.

Therefore, how to ensure that V2V messages, especially CAM type V2V messages, can better adapt to semi-static scheduling solutions has become a technical problem to be solved.

Summary of the invention

The present invention is based on at least one of the above technical problems, and proposes a new resource scheduling scheme for vehicle communication, which can be perceived by the base station in time when the message characteristics of the vehicle communication service performed by the vehicle communication terminal change.

detailed description

The present invention will be further described in detail below with reference to the drawings and specific embodiments. It should be noted that the embodiments in the present application and the features in the embodiments may be combined with each other without conflict.

In the following description, numerous specific details are set forth in order to provide a full understanding of the invention, but the invention may be practiced otherwise than as described herein. Limitations of the embodiments.

The technical solution of the present invention mainly considers that the message characteristics of the V2V service may change at any time. Therefore, in order to ensure that the transmission of the V2V message can be better adapted to the semi-persistent scheduling scenario, a V-UE or V2X application server is proposed. Auxiliary, so that the eNB can timely perceive the dynamic change of the period and/or size (ie, message characteristics) of the V2V message sent by the V-UE during the mobile process, and adjust the configuration parameters of the SPS in time. In this regard, the present invention mainly proposes the following two solutions: the first solution is a V-UE assisted solution; the second solution is a V2X application server-assisted solution. The following two scenarios are described in detail separately:

Solution 1: V-UE assisted solution

As shown in FIG. 3, the solution specifically includes the following steps:

Step 302: The V-UE indicates the message feature of the V2V service to the eNB by using indication signaling. Among them, the message characteristics include message period and/or size.

In step 304, the eNB performs an SPS initialization process for the V-UE. Among them, SPS initialization The process includes assigning initial SPS configuration parameters to the V-UE.

In step 306, the eNB performs an SPS activation process for the V-UE.

It should be noted that, in the interaction process shown in FIG. 3, the V-UE sends the message feature of the V2V service to the eNB when the V2V service needs to be performed, and then the eNB performs the SPS initialization and the SPS activation process according to the message feature. In other embodiments of the invention, the SPS initialization and SPS activation procedures may also be performed by pre-estimation of the eNB.

Step 308: The V-UE sends a V2V message, where the message period and size are unchanged.

Step 310: The V-UE detects, in the process of sending the V2V message, whether the message feature of the V2V service is sent and changed in the period T1. If yes, step 312 is performed. The size setting of T1 must be less than or equal to the V2V message period to ensure that the change can be detected when the message characteristics of the V2V service change.

Step 312: The V-UE indicates to the eNB, by using indication signaling, a new message feature of the V2V service. Among them, the new message features include the changed message period and/or size.

In step 314, the eNB performs an SPS reconfiguration process according to the new message feature. The SPS reconfiguration process includes reallocating SPS configuration parameters to the V-UE.

In step 316, the eNB performs an SPS reactivation process according to the SPS configuration parameters re-allocated to the V-UE.

Step 318: The V-UE sends the V2V message according to the changed message period and/or size.

Step 320: When the V-UE does not need to send the V2V message, the eNB performs an SPS release process, and releases the transmission resource allocated to the V-UE for dynamic scheduling of other V-UEs to avoid waste of resources.

In the first scheme, the indication signaling sent by the V-UE to the base station may be RRC signaling or MAC signaling. The specific signaling content includes: the message characteristics of the V2V service performed by the V-UE, such as the type of the message content, the message sending period, the message size, and the like.

As a preferred embodiment of the present invention, as shown in FIG. 4, the format of the indication signaling may include three parts, specifically:

The first portion 402 is identified by 1 bit and is used to distinguish whether the V2V message contains the portion of the authentication information.

The second portion 404 is identified by a log2M (rounded up) bit, which is used to indicate the period of the V2V message and the transmission time offset of the V2V message, and the size of the M depends on the number of V2V message periods. Wherein, the transmission time offset enables the base station to determine when the V-UE starts transmitting the vehicle communication message when the first transmission message (where the first transmission message refers to the first transmission of the message after SPS configuration/reconfiguration). Specifically, the transmission time offset is an offset with respect to the transmission time of the indication signaling.

The third part 406 is identified by a log2N (rounded up) bit, which is used to indicate the size of the V2V message. The size of the N depends on the number of V2V message size segments, similar to the buffer status report BSR (Buffer State Report). The data size Buffer Size classification method, and this value range is related to whether or not the authentication information is included (no authentication 92 to 260 Bytes, there are authentication 201 to 369 Bytes), that is, according to the bit of the first portion 402.

Option 2: V2X application server-assisted solution

As shown in FIG. 5, the solution specifically includes the following steps:

Step 502: The V2X application server indicates, by the indication signaling, the message feature of the V2V service performed by the V-UE to the eNB. Among them, the message characteristics include message period and/or size.

In step 504, the eNB performs an SPS initialization process for the V-UE. The SPS initialization process includes allocating initial SPS configuration parameters to the V-UE.

In step 506, the eNB performs an SPS activation process for the V-UE.

It should be noted that, in the interaction process shown in FIG. 5, the V2X application server sends the message feature of the V2V service to the eNB when detecting that the V-UE needs to perform V2V service, and then the eNB performs SPS initialization according to the message feature. And the SPS activation process. In other embodiments of the invention, the SPS initialization and SPS activation procedures may also be performed by pre-estimation of the eNB.

Step 508: The V-UE sends a V2V message, where the message period and size are unchanged.

In step 510, the V2X application server detects whether the message feature of the V2V service performed by the V-UE is changed in the period of the V-UE, and if yes, step 512 is performed. The size setting of T2 must be less than or equal to the V2V message period to ensure that the change can be detected when the message characteristics of the V2V service change.

Step 512: The V2X application server indicates to the eNB that the V2V service is new through the indication signaling. Message characteristics. Among them, the new message features include the changed message period and/or size.

In step 514, the eNB performs an SPS reconfiguration process according to the new message feature. The SPS reconfiguration process includes reallocating SPS configuration parameters to the V-UE.

In step 516, the eNB performs an SPS reactivation process according to the SPS configuration parameters re-allocated to the V-UE.

Step 518: The V-UE sends the V2V message according to the changed message period and/or size.

Step 520: When the V-UE does not need to send the V2V message, the eNB performs an SPS release process, and releases the transmission resource allocated to the V-UE for dynamic scheduling of other V-UEs to avoid waste of resources.

In the second solution, the indication signaling sent by the V2X application server to the eNB may be an application layer message sent to the eNB through a S-GW (Serving Gateway)/P-GW (Packet Data Network Gateway).

The specific signaling content may also include: a message feature of the V2V service performed by the V-UE, such as a message content type, a message sending period, a message size, and the like. As a preferred embodiment of the present invention, the format of the indication signaling may also be the format as shown in FIG.

The above is a detailed description of the V-UE-assisted and V2X-based application server-assisted SPS scheduling scheme proposed by the present invention, wherein the V-UE-assisted scheme is further divided into an RRC signaling indication and a MAC signaling indication manner. The solution based on the V2X application server is mainly indicated by the application layer information. The signaling overhead and delay of the above three methods in actual application are shown in Table 1:

	信令开销Signaling overhead	时延Delay
V-UE辅助(RRC)V-UE assistance (RRC)	中in	中in
V-UE辅助(MAC)V-UE assist (MAC)	高high	低low
V2X应用服务器辅助(应用层)V2X application server assistance (application layer)	低low	高high

Table 1

It can be seen from Table 1 that the signaling overhead and the delay of the scheme based on the V-UE assistance and indicated by the RRC signaling are all moderate; the signaling overhead of the scheme based on the V-UE assistance and indicated by the MAC signaling is higher. , but the delay is low; and based on the V2X application server auxiliary and pass The signaling overhead indicated by the application layer information is lower, but the delay is higher.

Therefore, for the delay-sensitive V2V service, if the signaling overhead is considered at the same time, the scheme based on V-UE assistance and indicated by RRC signaling is preferably adopted; for the V2V service in which the delay is not sensitive, the V2X-based service is preferably used. Application server assisted and indicated by application layer information.

In order to elaborate the technical solution of the present invention, the functional implementation of the V-UE, the application server, and the base station will be further described below with reference to FIG. 6 to FIG.

6 shows a schematic flow chart of a resource scheduling method for vehicle communication according to a first embodiment of the present invention, which is applicable to a vehicle communication terminal.

As shown in FIG. 6, a resource scheduling method for vehicle communication according to a first embodiment of the present invention includes:

Step S602: In the process of transmitting a vehicle communication message based on the configuration parameter of the semi-persistent scheduling allocated by the base station, detecting whether the message feature of the vehicle communication service changes.
