Detailed Description

The technical solutions in the embodiments of the present application will be described below with reference to the accompanying drawings.

It should be understood that the technical solution of the embodiment of the present invention can be applied to various Communication systems, such as a Global System for Mobile communications (GSM) System, a Code Division Multiple Access (CDMA) System, a Wideband Code Division Multiple Access (WCDMA) System, a long Term Evolution (L ong Term Evolution, L TE) System, a L TE Frequency Division Duplex (FDD) System, a L Time Division Duplex (TDD), a Universal Mobile Telecommunications System (UMTS), and a future 5G Communication System.

The access terminal may be a cellular phone, a cordless phone, a Session Initiation Protocol (SIP) phone, a Wireless local loop (Wireless L door L oop, W LL) station, a Personal Digital Assistant (PDA), a handheld device with Wireless communication capability, a computing device or other processing device connected to a Wireless modem, a vehicle mounted device, a wearable device, a terminal device in a future 5G Network or a terminal device in a future evolved Public Mobile communication Network (Public L and Mobile Network, P L MN) Network, etc.

The network device may be a device for communicating with a terminal device, and for example, may be a Base Station (BTS) in a GSM system or a CDMA system, a Base Station (NodeB, NB) in a WCDMA system, an evolved Node B (eNB, or eNodeB) in an L TE system, or may be a relay Station, an access point, a vehicle-mounted device, a wearable device, and a network-side device in a future 5G network or a network-side device in a future evolved P L MN network.

Fig. 1 and 2 are schematic diagrams of an application scenario of the embodiment of the present application. Fig. 1 exemplarily shows one network device and two terminal devices, and optionally, the wireless communication system may include a plurality of network devices and each network device may include other numbers of terminal devices within the coverage area, which is not limited in this embodiment of the present invention. In addition, the wireless communication system may further include other Network entities such as a Mobile Management Entity (MME), a Serving Gateway (S-GW), a Packet Data Network Gateway (P-GW), and the like, but the embodiment of the present invention is not limited thereto.

Specifically, the terminal device 20 and the terminal device 30 can communicate in a D2D communication mode, and when performing D2D communication, the terminal device 20 and the terminal device 30 directly communicate via a D2D link, i.e., a Sidelink (S L). for example, as shown in fig. 1 or fig. 2, the terminal device 20 and the terminal device 30 directly communicate via a Sidelink, in fig. 1, the terminal device 20 and the terminal device 30 communicate via a Sidelink, and transmission resources thereof are allocated by a network device, and in fig. 2, the terminal device 20 and the terminal device 30 communicate via a Sidelink, and transmission resources thereof are autonomously selected by the terminal device without being allocated by the network device.

The D2D communication method may be used for Vehicle-to-Vehicle (V2V) communication or Vehicle-to-other device (V2X) communication. In V2X communication, X may refer to any device with wireless receiving and transmitting capability, such as but not limited to a slow moving wireless device, a fast moving vehicle-mounted device, or a network control node with wireless transmitting and receiving capability. It should be understood that the embodiment of the present invention is mainly applied to the scenario of V2X communication, but may also be applied to any other D2D communication scenario, and the embodiment of the present invention is not limited in this respect.

In the car networking system, there may be two types of terminal devices, namely, a terminal device with a listening capability such as a Vehicle User Equipment (VUE) or a Pedestrian hand-held terminal (PUE), and a terminal device without a listening capability such as a PUE. VUEs have higher processing capability and are generally powered by a storage battery in a vehicle, while PUE processing capability is lower, and reduction of power consumption is also a main factor to be considered by PUEs, so in the existing vehicle networking system, VUEs are considered to have complete receiving capability and listening capability; while PUEs are considered to have partial or no receiving and listening capabilities. If the PUE has partial interception capability, the resources can be selected by adopting an interception method similar to that of the VUE, and available resources can be selected on the intercepted resources; and if the PUE does not have the interception capability, the PUE randomly selects transmission resources in the resource pool.

In the V2X system, in order to improve data throughput, multicarrier transmission is introduced, and a terminal device may use multiple carriers for traffic transmission. When the terminal device has different service types or the same service type but different service priorities (also referred to as priorities for short), there is a correspondence between the different service types or different priorities and the carriers, that is, data of some services or priorities can only be transmitted on the carriers corresponding to them. It should be understood that the service in the embodiments of the present application may also be referred to as data or service data.

For example, the service types are divided into two categories, i.e., basic security messages and entertainment messages. Assuming that the system supports 2 carriers, the correspondence between the service types and the carriers is shown in table one. According to table one, both carrier 1 and carrier 2 can be used for basic security messaging, but entertainment messaging can only be sent on carrier 2.

Watch 1

Type of service	Can use carrier wave
Basic security messages	Carrier	1, carrier 2
Entertainment message	Carrier 2

For another example, for a certain service, the service may be classified into different priorities, that is, a ProSe Per Packet Priority (PPPP) of neighboring services, which is in a range of 1 to 8, where the highest Priority is PPPP1 and the lowest Priority is PPPP 8. The lower the value of the priority, the higher the priority of the traffic. For example, assuming that the system supports 2 carriers, the basic safety message is divided into 2 priorities, i.e., priority 1 and priority 2. Assuming that the system supports 2 carriers, the correspondence between the priority and the carrier is shown in table two, for example. According to table two, carrier 1 and carrier 2 can both be used to transmit traffic with a traffic priority PPPP ═ 1, while traffic with a traffic priority PPPP ═ 2 can only be transmitted on carrier 2.

Watch two

Priority of service	Can use carrier wave
PPPP＝1	Carrier 1, carrier 2
PPPP＝2	Carrier 2

Taking table two as an example, for example, as shown in fig. 3, assuming that the terminal device has a service arrival with PPPP of 2 at time T1, a resource request message may be sent to the network to request transmission of resources, and the network device allocates one resource at time T3 on carrier 2 according to the correspondence between the service priority and the carrier shown in table two. If the terminal device has a service with PPPP of 1 at time T2, the terminal device initiates a resource request message to the network again to request for transmitting resources, and the network device allocates a resource at time T4 on carrier 1 according to the correspondence between the service priority and the carriers. However, when the time T3 is reached, since the PPPP-1 and PPPP-2 services are both to be transmitted, the terminal device may transmit the PPPP-1 service on the resource of carrier 2 in order to preferentially ensure the high priority service to be transmitted first, and at the time T4, since the PPPP-1 service has been transmitted, only the PPPP-2 service remains, but the PPPP-2 service cannot be transmitted on the resource of carrier 1 according to the correspondence relationship between the service priority and the carrier shown in table two, and thus the PPPP-2 service may not be transmitted normally.

Just because the services to be transmitted with different priorities or service types can only be transmitted on the corresponding carriers, if the terminal device occupies the transmission resources of other low-priority services for preferentially transmitting the high-priority services, the transmission of other low-priority services will be affected.

In the embodiment of the application, the network device allocates the transmission resources for the service to be transmitted of the terminal device based on the priority of the service to be transmitted, so that reasonable resource allocation can be realized to ensure normal transmission of services of different grades.

FIG. 4 is a flowchart interaction diagram of a method 400 of resource authorization according to one embodiment of the application. The terminal device shown in fig. 4 may be, for example, the terminal device 20 or the terminal device 30 shown in fig. 1 or fig. 2. The network device shown in fig. 4 may be, for example, the network device 10 shown in fig. 1 or fig. 2. As shown in fig. 4, the method includes:

in 410, the network device sends downlink control information DCI to the terminal device, where the DCI includes information of a transmission resource and information of a service class that a service to be transmitted on the transmission resource should have.

Wherein optionally the service class comprises a service priority (PPPP) and/or a service type (e.g. basic security messages or entertainment messages, etc.).

In 420, the terminal device receives the downlink control information DCI transmitted by the network device.

In 430, the terminal device sends the traffic with the traffic class to other terminal devices on the transmission resource.

It can be seen that, in this embodiment, when the network device sends the resource authorization message, for example, the DCI described herein, the network device determines, based on the received DCI, what class of service should be transmitted in each transmission resource by carrying, in the DCI, the transmission resource scheduled by the DCI and the service class that the service transmitted on the transmission resource should satisfy, so that it is ensured that the transmission resource of the low-class service is not occupied at will.

Taking table two as an example, it is assumed that the terminal device has traffic arrival of PPPP2 and PPPP1, respectively, and sends a resource request message to the network to request the network device to allocate transmission resources for the two traffic. According to the correspondence between the service priority and the carrier shown in table two, the network device allocates resource 1 on carrier 2 for the service whose PPPP is 1, and allocates resource 2 on carrier 2 for the service whose PPPP is 2. In this case, when the network device instructs the terminal device about the transmission resource, the network device carries information of resource 1 and information of traffic priority PPPP corresponding to the resource 1 in one DCI, and carries information of resource 2 and information of traffic priority PPPP corresponding to the resource 2 in another DCI.

Therefore, after receiving the two DCIs, the terminal device knows that only the service with the PPPP-1 service priority can be transmitted on resource 1, and the service with the PPPP-2 service can be transmitted on resource 2, so that the terminal device does not have to preferentially transmit the service with the PPPP-1 service on resource 2, and thus the transmission of the service with the PPPP-2 service is not affected.

The network device may specifically display or implicitly indicate to the terminal device the service level of the service that should be transmitted on the transmission resource allocated to the terminal device.

Optionally, when the traffic classes are different, the values at the bits in the DCI for indicating the traffic classes are different.

In this embodiment, a plurality of traffic classes are in one-to-one correspondence with a plurality of values, and when the values represented by the bits are different, the traffic classes indicated by the DCI are also different. For example, according to table two, when the value of the bit is 0, the traffic priority indicated by the DCI is PPPP1, and when the value of the bit is 1, the traffic priority indicated by the DCI is PPPP 2.

Optionally, when the service classes are different, the mask sequences of the DCI are different.

In this embodiment, multiple service classes correspond to multiple mask sequences one to one, and the information of the service class included in the DCI is implicitly represented by the mask sequence of the DCI. When the mask sequences of the DCI are different, the traffic classes indicated by the DCI are also different. For example, when the mask sequence of the DCI is P1, the traffic priority indicated by the DCI is PPPP-1, and when the mask sequence of the DCI is P2, the traffic priority indicated by the DCI is PPPP-2.

Optionally, when the service classes are different, the scrambling code sequences of the DCI are different.

In this embodiment, multiple service classes correspond to multiple scrambling code sequences one to one, and the information about the service classes included in the DCI is implicitly represented by the scrambling code sequence of the DCI. When the scrambling code sequences of the DCI are different, the traffic classes indicated by the DCI are also different. For example, when the scrambling sequence of the DCI is R1, the traffic priority indicated by the DCI is PPPP-1, and when the scrambling sequence of the DCI is R2, the traffic priority indicated by the DCI is PPPP-2.

Before sending the DCI to the terminal device, the network device may determine the service level of the service to be transmitted on different transmission resources according to the correspondence between the service level and the carrier set.

Optionally, the multiple service classes respectively correspond to multiple carrier sets, and the transmission resource included in the DCI sent by the network device in 410 is a resource in a carrier set corresponding to a service class included in the DCI.

The correspondence between the multiple service classes and the multiple carrier sets may be represented by, for example, a mapping table, a formula, a pattern, and the like, which is not limited in the embodiment of the present application. The corresponding relation can be sent to the terminal device in a network configuration mode or prestored in the terminal device. Moreover, a carrier set corresponding to one service class may include one or more carriers, and a plurality of carrier sets may be partially different or all different.

For example, as shown in table one, the carrier set corresponding to the basic security message includes multiple carriers, i.e., carrier 1 and carrier 2, and the carrier set corresponding to the entertainment message includes one carrier, i.e., carrier 2. The carrier 2 in the carrier set corresponding to the basic safety message is the same as the carrier 2 in the carrier set corresponding to the entertainment message, but the carrier 1 is not included in the carrier set corresponding to the entertainment message.

For example, as shown in table two, the carrier set corresponding to PPPP ═ 1 includes a plurality of carriers, i.e., carrier 1 and carrier 2, and the carrier set corresponding to PPPP ═ 2 includes one carrier, i.e., carrier 2. Carrier 2 in the carrier set corresponding to PPPP ═ 1 is the same as carrier 2 in the carrier set corresponding to PPPP ═ 2, but carrier 1 is not included in the carrier set corresponding to PPPP ═ 2.

Fig. 5 is a flowchart of a method 500 for resource authorization according to another embodiment of the present application. The terminal device shown in fig. 5 may be, for example, the terminal device 20 or the terminal device 30 shown in fig. 1 or fig. 2. The network device shown in fig. 5 may be, for example, the network device 10 shown in fig. 1 or fig. 2. As shown in fig. 5, the method includes:

in 510, the terminal device sends M resource request messages to the network device.

Wherein, each resource request message comprises at least one service grade of the service to be transmitted.

Wherein M is a positive integer.

Optionally, the service class comprises a service priority and/or a service type.

In 520, the network device receives M resource request messages sent by the terminal device.

At 530, the network device sequentially sends M DCI messages to the terminal device according to the M resource request messages.

Wherein, the transmission resource scheduled by the ith-sent DCI is a resource in a carrier set corresponding to the highest service level included in the ith resource request message arranged in a predetermined order in the M resource request messages, wherein multiple service levels respectively correspond to multiple carrier sets, and the multiple carrier sets are at least partially different.

Wherein i is from 1 to M.

In 540, the terminal device sequentially receives the M pieces of DCI transmitted by the network device.

The transmission resource scheduled by the DCI sent by the network device for the ith time is a resource in a carrier set corresponding to the highest service level included in the resource request message of the ith bit arranged in a predetermined order in the M resource request messages.

Optionally, the plurality of service classes respectively correspond to a plurality of carrier sets, and the plurality of carrier sets are at least partially different.

Optionally, the predetermined order of the M resource request messages is an order in which the M resource request messages are arranged from high to low (or from low to high) according to the included highest service level.

In 550, the terminal device sends the service to be transmitted to other terminal devices according to the receiving order of the M pieces of DCI.

Wherein, the highest service grade of the service transmitted by the terminal device on the transmission resource scheduled by the i +1 th received DCI is lower than or equal to the highest service grade of the service transmitted by the terminal device on the transmission resource scheduled by the i-th received DCI.

Specifically, the terminal device sends M resource request messages to the network device, where each resource request message includes at least one service class of a service to be transmitted of the terminal device, and after receiving the resource request message, the network device allocates a transmission resource for transmitting the service to be transmitted corresponding to the resource request message according to a highest service class of the at least one service class carried in each resource request message. The transmission resource is a transmission resource in a carrier set corresponding to the highest service level carried in the resource request message. After the network device performs resource allocation, the service to be transmitted corresponding to each resource request message is configured with corresponding transmission resources. At this time, the network device may indicate M transmission resources to the terminal device through the M pieces of DCI, respectively. The network device sequentially sends M DCIs corresponding to the M resource request messages to the terminal device according to the highest service level of the service to be transmitted included in the M resource request messages and the sequence from the highest service level to the lowest service level carried by the M resource request messages, namely, the M resource requests are sequenced according to the sequence from the highest service level to the lowest service level of the service to be transmitted in the M resource request messages, and the transmission resource scheduled by the DCI sent for the ith time is the resource arranged in the carrier set corresponding to the highest service level of the service to be transmitted included in the ith scheduling request message. Therefore, the terminal device can know which resource the services with different service levels are transmitted on according to the sequence of receiving the M DCIs, wherein the highest service level of the service transmitted by the terminal device on the transmission resource scheduled by the (i + 1) th received DCI is lower than or equal to the highest service level of the service transmitted by the terminal device on the transmission resource scheduled by the ith received DCI, namely, the terminal device transmits the service with the high service level on the transmission resource scheduled by the DCI received firstly, and transmits the service with the next service level on the transmission resource scheduled by the DCI received secondly.

Therefore, the network device indicates the transmission resources for transmitting the services of different grades to the terminal device through the sending sequence of the DCI, and the terminal device determines the transmission resources for transmitting the services of different grades through the receiving sequence of the DCI and transmits the services meeting the corresponding service grades on each transmission resource, thereby realizing reasonable resource allocation and ensuring the normal transmission of the services of different grades.

Taking fig. 6 as an example, in conjunction with table two, it is assumed that the terminal device has arrived at the time T1 and T2 with the PPPP-2 and PPPP-1 services, respectively, and has sent a resource request message to the network to request the network device to allocate transmission resources for the two services. According to the correspondence between the service priority and the carrier shown in table two, the network device allocates resource 1 on carrier 1 for the service whose PPPP is 1, and allocates resource 2 on carrier 2 for the service whose PPPP is 2. At this time, when the network device indicates the transmission resource to the terminal device, according to the order of priority from high to low, the DCI of scheduling resource 1 is transmitted first, and then the DCI of scheduling resource 2 is transmitted again.

The terminal device receives the DCI scheduled transmission resource first as resource 1 and receives the DCI scheduled transmission resource later as resource 2, so that the terminal device preferentially transmits the service with PPPP equal to 1 on resource 1 and then transmits the service with PPPP equal to 2 on resource 2.

Optionally, the service of each service class in the multiple service classes can be transmitted in the carrier set corresponding to the service class, and the service of each service class, together with the service of which the service class is higher than the service class of itself, can be simultaneously transmitted in the carrier set corresponding to the service class higher than the service class of itself.

The service of each service class in the multiple service classes can be transmitted in the carrier set corresponding to the service class, that is, the service of each service class can be transmitted on the carrier corresponding to the service class, for example, in table 2, the service of PPPP1 can be transmitted on carrier 1 and carrier 2, and the service of PPPP2 can be transmitted on carrier 2.

The service of each service class and the service with the service class higher than the service class thereof can be transmitted in the carrier set corresponding to the service class higher than the service class thereof at the same time, which means that when the service of each service class and the high-grade service are packed and transmitted together, the service can be transmitted on the carrier corresponding to the high grade. For example, the network device transmits one resource 1 in a first-transmitted DCI scheduling carrier 1 and one resource 2 in a second-transmitted DCI scheduling carrier 2, the terminal device transmits a service with PPPP equal to 1 on the first-received DCI scheduled resource 1, if the service with PPPP equal to 1 is small but the resource 1 is large, after the transmission of the service with PPPP equal to 1, there may be remaining resources available for transmitting a part of the service with PPPP equal to 2 to be transmitted later, at this time, the part of the service with PPPP equal to 2 can be transmitted in the resource of the carrier 1 together with the service with PPPP equal to 1, and the remaining service with PPPP equal to 2 can be transmitted on the second-received DCI scheduled resource 2.

In any case, the highest traffic class of the traffic transmitted by the terminal device on the transmission resource scheduled by the i +1 th received DCI is always lower than or equal to the highest traffic class of the traffic transmitted by the terminal device on the transmission resource scheduled by the i-th received DCI.

In addition, in the embodiment of the present application, for services with the same service class, the terminal device may transmit the services based on its own implementation manner, for example, the services with the same service class are sequentially sent according to the order of service arrival, where a service that arrives first is preferentially sent, and a service that arrives later is then sent.
