Detailed Description
The following description of the technical solutions according to the embodiments of the present application will be given with reference to the accompanying drawings in the embodiments of the present application, and it is apparent that the described embodiments are some embodiments of the present application, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the application without making any inventive effort, are intended to be within the scope of the application.
It should be understood that the technical solution of the embodiment of the present application may be applied to an end-to-end (D2D) communication system, for example, an internet of vehicles system for D2D communication based on long term evolution (Long Term Evolution, LTE), or an NR-V2X system. Unlike the conventional LTE system in which communication data between terminals is received or transmitted through a network device (e.g., a base station), the internet of vehicles system adopts a terminal-to-terminal direct communication manner, and thus has higher spectral efficiency and lower transmission delay.
In one embodiment, the communication system based on the internet of vehicles system may be a global system for mobile communications (Global System of Mobile communication, GSM) system, a code division multiple access (Code Division Multiple Access, CDMA) system, a wideband code division multiple access (Wideband Code Division Multiple Access, WCDMA) system, a general packet Radio service (General Packet Radio Service, GPRS), an LTE system, an LTE frequency division duplex (Frequency Division Duplex, FDD) system, an LTE time division duplex (Time Division Duplex, TDD) system, a universal mobile telecommunications system (Universal Mobile Telecommunication System, UMTS), a worldwide interoperability for microwave access (Worldwide Interoperability for Microwave Access, wiMAX) communication system, a 5G New Radio (NR) system, and the like.
The network device in the embodiment of the present application may be a base station (Base Transceiver Station, BTS) in a GSM system or a CDMA system, a base station (NodeB, NB) in a WCDMA system, an evolved base station (Evolutional Node B, eNB or eNodeB) in an LTE system, or a radio controller in a cloud radio access network (Cloud Radio Access Network, CRAN), or the network device may be a mobile switching center, a relay station, an access point, a vehicle device, a wearable device, a hub, a switch, a bridge, a router, a network side device (gNB) in an NR network, or a network device in a public land mobile network (Public Land Mobile Network, PLMN) of future evolution, etc.
The terminal device in the embodiment of the application can be a terminal device capable of realizing D2D communication. For example, the present application may be a vehicle-mounted terminal device, a terminal device in an LTE system (LTE UE), a terminal device in an NR network (NR UE), or a terminal device in a future evolved public land mobile network (Public Land Mobile Network, PLMN), etc., and the embodiment of the present application is not limited.
Fig. 1 is a schematic diagram of an application scenario according to an embodiment of the present application. Fig. 1 illustrates one network device and two terminal devices, and in one embodiment, the wireless communication system in the embodiment of the present application may include a plurality of network devices and may include other number of terminal devices within a coverage area of each network device, which is not limited by the embodiment of the present application.
In one embodiment, the wireless communication system may further include other network entities such as a mobility management entity (Mobile Management Entity, MME), a Serving Gateway (S-GW), a packet data network Gateway (Packet Data Network Gateway, P-GW), or may further include other network entities such as a session management function (Session Management Function, SMF), unified data management (Unified Data Management, UDM), an authentication server function (Authentication Server Function, AUSF), which is not limited by the embodiments of the present application.
In the internet of vehicles system, the terminal equipment can adopt a mode A and a mode B for communication.
Specifically, the terminal device 121 and the terminal device 122 can communicate through the D2D communication mode, and at the time of D2D communication, the terminal device 121 and the terminal device 122 directly communicate through a D2D link, that is, a Side Link (SL). In mode a, the transmission resources of the terminal device are allocated by the base station, and the terminal device may transmit data on SL according to the resources allocated by the base station. The base station may allocate resources for single transmission to the terminal device, or may allocate resources for semi-static transmission to the terminal device. In mode B, the terminal device autonomously selects transmission resources on SL resources. Specifically, the terminal equipment acquires available transmission resources in the resource pool in a interception mode, or randomly selects one transmission resource from the resource pool.
It should be understood that the above modes a and B are merely exemplary of two transmission modes, and that other transmission modes may be defined. For example, a mode C and a mode D are introduced in NR-V2X, where mode C indicates that the side uplink transmission resource of the terminal device is allocated by the base station, and the base station may use the mode a and mode C to allocate the side uplink transmission resource differently, for example, one may use a dynamic scheduling manner, another may use a semi-static scheduling manner, or a semi-static plus dynamic scheduling manner, and mode D indicates that the side uplink transmission resource of the terminal device is selected by the terminal.
The D2D communication technology may be applied to vehicle-to-vehicle (Vehicle to Vehicle, simply "V2V") communication or vehicle-to-other device (Vehicle to Everything, V2X) communication. In V2X communications, X may refer broadly to any device having wireless receiving and transmitting capabilities, such as, but not limited to, a slow moving wireless device, a fast moving vehicle device, or a network control node having wireless transmitting and receiving capabilities, etc. It should be understood that the embodiment of the present application 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 application is not limited in any way.
Fig. 2 is a schematic flow chart of a method of wireless communication according to an embodiment of the present application. The method 200 may be performed by a terminal device in the communication system shown in fig. 1, and as shown in fig. 2, the method 200 may include at least part of the following:
s210, the first device determines a corresponding priority level of transmission of a first link of a first network or data of the first link in a second priority class of a second link of a second network, where the corresponding priority level is used to determine a link of the first link and the second link that is preferentially transmitted, and the transmission of the first link or the data of the first link is configured to use a first priority level in a first priority class, where the first priority class includes N priority levels, and the second priority class includes M priority levels, where N, M is a positive integer.
That is, the first device may determine a corresponding priority level of the first link of the first network in a second priority class, which may be a transmission for the second link of the second network or data of the second link of the second network.
In the embodiment of the present application, the first network and the second network are different types of networks, for example, the first network is an LTE network, and the second network is an NR network; for another example, the first network is an NR network, the second network is an LTE network, or the first network and the second network may be two other different types of networks, which is not limited in the embodiment of the present application.
In the embodiment of the present application, the first link and the second link may be the same type of link, for example, both are side links, or both are uplink links; alternatively, the first link and the second link may be different types of links, for example, the first link is a side link, and the second link is an uplink, which is not limited by the embodiment of the present application.
The first link of the first network may use a first priority level in a first priority class for transmission of the first link or data on the first link, and therefore, it may also be said that the transmission of the first link uses the first priority level in the first priority class or the data on the first link uses the first priority level in the first priority class.
The second link of the second network may use a second priority level in a second priority class for transmission of the second link or data on the second link, and therefore, it may also be said that the transmission of the second link uses the second priority level in the second priority class or the data on the second link uses the second priority level in the second priority class.
In an embodiment of the present application, the first priority class and the second priority class may include different numbers of priority classes, for example, the first priority class may include 16 priority classes, for example, 1-16, the second priority class may include 8 priority classes, for example, 1-8, or the first priority class and the second priority class may include other numbers of priority classes, which is not limited in the embodiment of the present application.
In some embodiments, the first priority class may indicate (PC 5 5G QoS Identifier,PQI) a priority for a PC5 5G quality of service (Quality of Service, qoS) associated with a radio bearer of the first link, or a logical channel priority corresponding to the first link, i.e., a priority of a logical channel used by the first link, or a resource grant priority of the first link, i.e., a priority of a grant resource used by the first link.
In some embodiments, the second priority class may be a PQI priority associated with a radio bearer of the second link, or a logical channel priority corresponding to the second link, that is, a priority of a logical channel used by the second link, or a resource grant priority of the second link, that is, a priority of a grant resource used by the second link.
If the first priority class and the second priority class include different numbers of priority classes, when the first link of the first network and the second link of the second network collide with each other, the first device may determine a corresponding priority (or referred to as a peer-to-peer priority, an equivalent priority) of the priority class used by one of the links in the priority class used by the other link, for example, the first device may determine a corresponding priority class of the first priority class used by the first link in the second priority class, that is, the first priority class in the first priority class corresponds to the corresponding priority class in the second priority class, and further, the first device may compare the corresponding priority class of the first link with the second priority class in the second priority class used by the second link, determine a link to be preferentially transmitted, that is, which link to transmit, or which link to preferentially transmit data.
In an embodiment of the present application, the occurrence of resource conflict between the first link and the second link may mean that the grant resources of the first link and the grant resources of the second link at least partially overlap in a time domain, or that the grant resources for transmitting the data of the first link and the grant resources for transmitting the data of the second link at least partially overlap.
It should be understood that the manner of determining the corresponding priority level in the embodiment of the present application may be applied to a scenario where resource conflicts occur in two links, or may also be applied to other scenarios where priority levels in different priority classes need to be converted, which is not limited in the embodiment of the present application.
In some embodiments, the transmission of the first link may refer to a transmission of a physical sidelink channel, which may be, for example, a physical sidelink shared channel (Physical Sidelink Shared Channel, PSSCH) and/or a physical sidelink control channel (Physical Sidelink Control Channel, PSCCH).
In other embodiments, the transmission of the first link may refer to a transmission of a physical uplink channel, which may be, for example, a physical uplink shared channel (Physical Uplink Shared Channel, PUSCH) and/or a physical uplink control channel (Physical Uplink Control Channel, PUCCH).
In some embodiments, the data of the first link may be sidelink data or uplink data, for example, media access control (Media Access Control, MAC) protocol data units (Protocol Data Unit, PDUs), or data to be transmitted on a logical channel, or the like.
The manner in which the priority levels in the first priority class are determined in the second priority class will be described below with reference to specific embodiments.
Example 1: the first device determines the corresponding priority level of the first priority level in the second priority level according to the first priority level and combining the number relation between the number N of the priority levels included in the first priority level and the number M of the priority levels included in the second priority level.
Example 1-1: and if the N is larger than the M, determining a result obtained by dividing the first priority level by K and rounding the result as a corresponding priority level of the first priority level in the second priority class, wherein K is a ratio of the N to the M.
As an embodiment, if the first priority class includes priority classes 1 to N and the second priority class includes priority classes 1 to M, a result obtained by dividing the priority class of the priority classes 1 to N by K and rounding up may be determined as a corresponding priority class in the second priority class.
For example, if N is 16, the priority levels are 1-16, M is 8, and the priority levels are 1-8, then the corresponding priority level of the first priority level X in the first priority class in the second priority class is a result of rounding up from X/2.
For another example, if the N is 16, the priority levels are 1-16, the M is 2, and the priority levels are 1-2, respectively, then the corresponding priority level of the first priority level X in the first priority class in the second priority class is a result of rounding up from X/8.
As another embodiment, if the first priority class includes priority classes 0 to N-1 and the second priority class includes priority classes 0 to M-1, the result obtained by dividing the priority class of the priority classes 0 to N-1 by K and rounding down may be determined as the corresponding priority class in the second priority class.
For example, if N is 16, the priority levels are 0-15, M is 8, and the priority levels are 0-7, then the corresponding priority level of the first priority level X in the first priority class in the second priority class is a result of rounding down from X/2.
For another example, if the N is 16, the priority levels are 0-15, the M is 2, and the priority levels are 0-1, then the corresponding priority level of the first priority level X in the first priority class in the second priority class is a result of rounding down from X/8.
Examples 1-2: and if the N is smaller than the M, determining a result obtained by multiplying the first priority level by P and subtracting Q from the first priority level as a corresponding priority level of the first priority level in the second priority class, wherein P is a ratio of the M to the N, and Q is an integer smaller than P.
For example, if N is 8, the priority levels are 1-8, M is 16, and the priority levels are 1-16, then the corresponding priority level of the first priority level X in the first priority class in the second priority class is 2X or 2X-1;
for another example, the N is 2, the priority levels are 1-2, the M is 16, and the priority levels are 1-16, respectively, and then the corresponding priority level of the first priority level X in the first priority class in the second priority class is 8X-Q, where Q is an integer less than 8, for example, 0 or 7, etc.
In some embodiments, if the first priority class includes priority classes 0 to N-1 and the second priority class includes priority classes 0 to M-1, in this embodiment 1-2, the first device may determine a result of multiplying the first priority class by P and subtracting Q from the first priority class, where P is a ratio of K to N, and Q is an integer smaller than P.
For example, if N is 8, the priority levels are 0-7, M is 16, and the priority levels are 0-15, then the corresponding priority level of the first priority level X in the first priority class in the second priority class is 2 (x+1) or 2 (x+1) -1;
for another example, if N is 2, the priority levels are 0-1, M is 16, and the priority levels are 0-15, then the corresponding priority level of the first priority level X in the first priority class in the second priority class is 8 (x+1) or 8 (x+1) -1.
It should be understood that, in the embodiment of the present application, N and M are only used to represent the number of priority levels, and the embodiment of the present application is not limited to a specific manner of representing priority levels in priority classification, and, for example, N priority levels may be used to represent N priority levels from 1 to N, or may be used to represent N priority levels from 0 to N-1, or may be used to represent N priority levels in other manners, which is not limited in the embodiment of the present application.
Note that, in this embodiment 1, the manner of determining the corresponding priority level according to the relationship between the numbers of priority levels included in the two priority classes is mainly based on the expression of 1 to N, and when the priority levels in the priority classes are expressed in other ways, the numerical value of the priority level may be converted into the priority level order in the priority class, which may be 1 to N, and then calculated according to the priority level order in combination with the calculation manner in embodiment 1. If the M priority levels of the second priority class are not represented by the representation of 1 to M, the corresponding priority level may be understood as a priority level order after the corresponding priority level is obtained according to the calculation method in embodiment 1, and the priority level of the priority level order in the second priority class may be further determined as the target corresponding priority level of the first priority level.
For example, the first priority class includes 4 priority classes, 1,3,5,7, respectively, the priority classes are 1,3,5,7 in the order from high to low, the second priority class includes 8 priority classes, 0-7 respectively, and when determining that the priority class 3 in the first priority class is the corresponding priority class in the second priority class, the priority class 3 may be converted into the priority class order 2 first, then according to embodiments 1-2, the corresponding priority class 3 or 4 is determined, and since the second priority class is started from 0, the corresponding priority class 3 or 4 may be understood as the priority class orders 3 and 4, and further the third and fourth highest priority classes in the second priority class, i.e., the priority class 2 or 3 is the corresponding priority class of the priority class 3, may be determined.
It should be understood that in the embodiment of the present application, the order of the first priority level in the N priority levels is the same as the order of the corresponding priority levels in the N corresponding priority levels, where the N corresponding priority levels are the corresponding priority levels of the N priority levels in the second priority class. I.e. the priority order of the N priority levels in the first priority class is the same as the priority order of the N corresponding priority levels.
For example, if the first priority class includes priority class 1 and priority class 2, priority class 1 is higher than priority class 2, and the corresponding priorities of priority class 1 and priority class 2 in the second priority class are corresponding priority class 1 and corresponding priority class 2, respectively, where the priority class of corresponding priority class 1 is higher than or equal to the corresponding priority class 2.
Example 2: the first device may determine, according to the first priority level, a first mapping relationship, where the first mapping relationship is a correspondence between the N priority levels and the M priority levels, where the first priority level is a correspondence between the first priority level and the second priority level.
In some embodiments, if N is greater than M, in the first mapping relationship, one priority level in the second priority class may correspond to at least one priority level in the first priority class.
In other embodiments, if M is greater than N, in the first mapping relationship, one priority level in the first priority class may correspond to at least one priority level in the second priority class.
In other embodiments, the first mapping relationship may be configured by the network device, or may be configured by another terminal, or may be predefined.
Example 3: the first device determines a corresponding priority level of the first priority level in the second priority class according to a QoS upper layer indication, PQI, associated with a radio bearer of the first link.
In some embodiments, the priority level indicated by the PQI is the same as the range of priority levels included by the second priority class, in which case the corresponding priority level of the first priority level in the second priority class may be determined according to the QoS upper layer indication PQI associated with the radio bearer of the first link, e.g., the priority level indicated by the PQI may be the corresponding priority level of the first priority level in the second priority class.
Example 4: and determining the corresponding priority level of the first priority level in the second priority class according to the indication information of the second equipment, wherein the indication information is used for indicating the corresponding priority level of the first priority level in the second priority class.
In some embodiments, the second device may be a network device, where the network device may configure the first device with the corresponding priority level of the first priority level in the second priority class through the indication information, for example, the network device may configure the first device with information of the corresponding priority level through resource grant of the first link, where the indication information may be included in the configuration information of the resource grant of the first link, or the network device may also configure the first device with the corresponding priority level of the first priority level in the second priority class through other downlink information or downlink signaling, where the embodiment of the present application is not limited thereto.
In other embodiments, the second device may be a terminal device, and may be denoted as a second terminal, where the second terminal may configure, for example, information about the corresponding priority level in the second priority class, which may be configured by using the resource grant of the first link to the first device, where the indication information may be included in the configuration information about the resource grant of the first link, or the second terminal may also configure, for example, other side-going information or side-going signaling, the corresponding priority level in the second priority class, where the second terminal may also configure, for example, the corresponding priority level in the second priority class, where the first priority level may be configured by using the second terminal to the first device.
It should be appreciated that the above embodiments are described taking as an example the assignment of a priority level of one link to a priority class of another link, in other embodiments both priority levels of the two links may be assigned to a third priority class, for example, the assignment of a first priority level of a first link to a third priority class may be determined, and the assignment of a second priority level of a second link to a third priority class may be determined, and the assignment of the first priority level to the second priority level to the third priority class may be further compared, and the links of the first link and the second link for priority transmission may be determined.
For example, the first priority class includes 4 priority classes, the second priority class includes 6 priority classes, the priority classes in the first priority class and the second priority class may be corresponding to a third priority class, the third priority class may include a priority classes, the a may be a common multiple of the number of priority classes included in the first priority class and the second priority class, for example, a is 12, wherein the manner in which the priority classes in the first priority class and the second priority class are determined in the third priority class may refer to the related description of embodiment 1, and the description is omitted herein. Assuming that the priority level X in the first priority class corresponds to the priority level 3X in the third priority class and the priority level Y in the second priority class corresponds to the priority level 2Y in the third priority class, the first device may determine the priority level of the first link and the second link by comparing the corresponding priority levels 3X and 2Y.
Therefore, in the embodiment of the application, the first device can correspond the priority levels of the two links to the unified priority class under the condition that the link communication of the two different networks is in conflict, and further can compare the priorities based on the unified priority class, thereby being beneficial to improving the accuracy of priority judgment and further ensuring the priority transmission of the link with high priority.
