Detailed Description

Technical solutions in the embodiments of the present application will be described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are some embodiments of the present application, but not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

It should be understood that the technical solution of the embodiment of the present application may be applied to a Device to Device (D2D) communication system, for example, a vehicle networking system that performs D2D communication based on 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 car networking system adopts a terminal-to-terminal direct communication mode, and thus has higher spectral efficiency and lower transmission delay.

Alternatively, the communication System based on the car networking System may be a Global System for Mobile communication (GSM) System, a Code Division Multiple Access (CDMA) System, a Wideband Code Division Multiple Access (WCDMA) System, a General Packet Radio Service (GPRS), an LTE System, an LTE Frequency Division Duplex (FDD) System, an LTE Time Division Duplex (TDD), a Universal Mobile Telecommunications System (UMTS), a Worldwide Interoperability for Microwave Access (WiMAX) communication System, a 5G New Radio (NR) System, and the like.

The Network device in this embodiment may be a Base Transceiver 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 LTE system, or a wireless controller in a Cloud Radio Access Network (CRAN), or may be a Network device in a Mobile switching center, a relay Station, an Access point, a vehicle-mounted 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 future evolved Public Land Mobile Network (PLMN), or the like.

The terminal device in the embodiment of the present application may be a terminal device capable of implementing D2D communication. For example, the terminal device may be a vehicle-mounted terminal device, or may also be a terminal device in an LTE system (LTE UE), a terminal device in an NR Network (NR UE), a terminal device in a Public Land Mobile Network (PLMN) that is an evolution in the future, and the like, and the embodiment of the present application is not limited.

Fig. 1 is a schematic diagram of an application scenario of an embodiment of the present application. Fig. 1 exemplarily shows one network device and two terminal devices, and optionally, the wireless communication system in the embodiment of the present application may include a plurality of network devices and may include other numbers of terminal devices within the coverage of each network device, which is not limited in the embodiment of the present application.

Optionally, 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, or the wireless communication system may further include other Network entities such as a Session Management Function (SMF), a Unified Data Management (UDM), an Authentication Server Function (AUSF), and the like, which is not limited in this embodiment.

In the vehicle networking system, the terminal device can communicate in the mode a and the mode B.

Specifically, the terminal device 121 and the terminal device 122 can communicate through the D2D communication mode, and when the D2D communication is performed, the terminal device 121 and the terminal device 122 directly communicate through a D2D link, i.e., a SideLink (SL). In mode a, the transmission resource of the terminal device is allocated by the base station, and the terminal device may transmit data on SL according to the resource 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 the SL resources. Specifically, the terminal device obtains an available transmission resource in the resource pool by means of interception, or the terminal device randomly selects a transmission resource from the resource pool.

It should be understood that the above-mentioned mode a and mode B are only exemplary to illustrate two transmission modes, and other transmission modes may be defined. For example, a mode C and a mode D are introduced in NR-V2X, where the mode C indicates that sidelink transmission resources of the terminal device are allocated by the base station, and the manner in which the base station allocates the sidelink transmission resources using the mode a and the mode C may be different, for example, one of the manners may employ dynamic scheduling, the other manner may employ semi-static scheduling, or the manner employing semi-static plus dynamic scheduling, and the mode D indicates that the sidelink transmission resources of the terminal device are selected by the terminal.

The D2D communication technology can be applied to 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.

Fig. 2 is a schematic flow chart of a method for wireless communication according to an embodiment of the present disclosure. 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, a first device determines a corresponding priority level of a transmission of a first link of a first network or a data of the first link in a second priority level of a second link of a second network, where the corresponding priority level is used to determine a link that is preferentially transmitted in the first link and the second link, where the transmission of the first link or the data of the first link is configured to use a first priority level in the first priority level, the first priority level includes N priority levels, the second priority level includes M priority levels, and N and M are positive integers.

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 for transmission of the second link of the second network or data of the second link of the second network.

In this embodiment, 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 this 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 sidelink links, or both uplink links; alternatively, the first link and the second link may be different types of links, for example, the first link is a sidelink, and the second link is an uplink, which is not limited in this embodiment of the present application.

The first link of the first network may use a first priority class of the first priority class for transmission of the first link, or for transmission of data on the first link, and therefore, it may also be said that the transmission of the first link uses a first priority class of the first priority class, or the data on the first link uses a first priority class of the first priority class.

The second link of the second network may use a second priority class in the second priority class for transmission of the second link, or for transmission of data on the second link, so that it can also be said that the transmission of the second link uses the second priority class in the second priority class, or the data on the second link uses the second priority class in the second priority class.

Optionally, in this embodiment of the present application, the first priority classification and the second priority classification may include different numbers of priority levels, for example, the first priority classification may include 16 priority levels, for example, 1 to 16, the second priority classification may include 8 priority levels, for example, 1 to 8, or the first priority classification and the second priority classification may include other numbers of priority levels, which is not limited in this embodiment of the present application.

Optionally, in some embodiments, the first priority classification may be a Quality of Service (QoS) indication (PC 55G QoS Identifier, PQI) priority of a PC 55G associated with a radio bearer of the first link, or a logical channel priority corresponding to the first link, that is, a priority of a logical channel used by the first link, or a resource grant priority of the first link, that is, a priority of a granted resource used by the first link.

Optionally, in some embodiments, the second priority classification 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 authorization priority of the second link, that is, a priority of authorized resources used by the second link.

If the first priority class and the second priority class comprise different numbers of priority classes, when a first link of the first network and a second link of the second network have resource conflict, the first device may determine a corresponding priority class of the priority class used by one of the links in the priority class used by the other link (or referred to as equal priority, or equivalent priority), 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, a first priority class in the first priority class is equivalent 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 a second priority class in the second priority class used by the second link, the link of the first link and the second link that is preferentially transmitted is determined, that is, the link that is preferentially transmitted, or the link that is preferentially transmitted.

Optionally, in this embodiment of the application, the occurrence of the resource conflict between the first link and the second link may mean that the granted resource of the first link and the granted resource of the second link at least partially overlap in a time domain, or that the granted resource for transmitting the data of the first link and the granted resource for transmitting the data of the second link at least partially overlap.

It should be understood that the determination manner of the corresponding priority level in the embodiment of the present application may be applied to a scenario where resource conflicts occur between 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.

Optionally, in some embodiments, the transmission of the first link may refer to transmission of a Physical Sidelink Channel, for example, the Physical Sidelink Channel may be a Physical Sidelink Shared Channel (psch) and/or a Physical Sidelink Control Channel (PSCCH).

Optionally, in other embodiments, the transmission of the first link may refer to transmission of a Physical Uplink Channel, for example, the Physical Uplink Channel may be a Physical Uplink Shared Channel (PUSCH) and/or a Physical Uplink Control Channel (PUCCH).

Optionally, in some embodiments, the Data of the first link may be side-line Data or uplink Data, for example, a Media Access Control (MAC) Protocol Data Unit (PDU), or Data to be transmitted on a logical channel.

Hereinafter, a manner of determining a corresponding priority level in the first priority class to the second priority class will be described with reference to a specific embodiment.

Example 1: and the first equipment determines the corresponding priority level of the first priority level in the second priority level according to the first priority level and by combining the quantity relation between the quantity N of the priority levels included in the first priority level and the quantity 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 as a corresponding priority level of the first priority level in the second priority level, wherein the K is the 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 a 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 to 16, M is 8, and the priority levels are 1 to 8, respectively, 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 by X/2.

For another example, if N is 16, the priority levels are 1 to 16, M is 2, and the priority levels are 1 to 2, respectively, 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 by X/8.

As another embodiment, if the first priority class includes priority levels 0 to N-1 and the second priority class includes priority levels 0 to M-1, the result obtained by dividing the priority level of the priority levels 0 to N-1 by K and rounding down may be determined as the corresponding priority level in the second priority class.

For example, if N is 16, the priority levels are 0 to 15, M is 8, and the priority levels are 0 to 7, 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 down by X/2.

For another example, if N is 16, the priority ranks are 0 to 15, M is 2, and the priority ranks are 0 to 1, respectively, the corresponding priority rank of the first priority rank X in the first priority class in the second priority class is a result of rounding down by X/8.

Examples 1 to 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 as a corresponding priority level of the first priority level in the second priority level, 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 to 8, M is 16, and the priority levels are 1 to 16, respectively, 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, if N is 2, the priority levels are 1-2, M is 16, and the priority levels are 1-16, the corresponding priority level of the first priority level X in the first priority level in the second priority level is 8X-Q, wherein Q is an integer less than 8, e.g., 0 or 7.

In some embodiments, if the first priority class includes priority levels 0 to N-1 and the second priority class includes priority levels 0 to M-1, in this embodiment 1-2, the first device may determine a result of adding and multiplying the first priority class by P and then subtracting Q as a corresponding priority level of the first priority class in the second priority class, where P is a ratio of M to N and Q is an integer less than P.

For example, if N is 8, the priority levels are 0-7, respectively, M is 16, and the priority levels are 0-15, respectively, 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 to 1, M is 16, and the priority levels are 0 to 15, respectively, the first priority level X in the first priority class corresponds to a priority level of 8(X +1) or 8(X +1) -1 in the second priority class.

It should be understood that, in the embodiment of the present application, N and M are only used to indicate the number of priority levels, and the embodiment of the present application does not specifically limit the manner of indicating the priority levels in the priority classes, and taking N priority levels as an example, N priority levels may indicate N priority levels from 1 to N, or 0 to N-1 may indicate the N priority levels, or other manners may also indicate the N priority levels, which is not limited in the embodiment of the present application.

It should be noted that, in embodiment 1, the manner of determining the corresponding priority level according to the relationship between the numbers of the priority levels included in the two priority classifications is mainly based on the expression manner from 1 to N, and when the priority levels in the priority classifications adopt other expression manners, the numerical values of the priority levels may be first converted into the priority level order in the priority classifications, where the priority level order may be from 1 to N, and then the calculation manner in embodiment 1 may be combined according to the priority level order. If the M priority levels of the second priority classification are not represented in the 1 to M representation manner, after the corresponding priority levels are obtained according to the calculation method in embodiment 1, the corresponding priority levels may be understood as a priority level order, and the priority level of the priority level order in the second priority classification may be further determined as a target corresponding priority level of the first priority level.

For example, the first priority class includes 4 priority levels, 1, 3, 5, 7 respectively, with the order of priority levels from high to low being 1, 3, 5, 7, the second priority class includes 8 priority levels, 0-7 respectively, then upon determining that priority level 3 in the first priority class is at the corresponding priority level in the second priority class, this priority level 3 may first be converted into a priority level order of 2, and then, according to embodiments 1-2, the corresponding priority level is determined to be 3 or 4, since the second priority classification is started from 0, the corresponding priority class 3 or 4 may be understood as priority class order 3 and 4, and further the third and fourth highest priority class in the second priority classification, i.e. priority class 2 or 3, may be determined as the corresponding priority class of the priority class 3.

It should be understood that, in the embodiments of the present application, an order of the first priority class among the N priority classes is the same as an order of the corresponding priority class among N corresponding priority classes, where the N corresponding priority classes are corresponding priority classes of the N priority classes among the second priority classes. I.e. the priority order of the N priority classes in the first priority class is the same as the priority order of the N corresponding priority classes.

For example, if the first priority class comprises a priority class 1 and a priority class 2, the priority class 1 being higher than the priority class 2, the corresponding priority classes of the priority class 1 and the priority class 2 in the second priority class are a corresponding priority class 1 and a corresponding priority class 2, respectively, wherein the priority class corresponding to the 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 corresponding priority level of the first priority level in the second priority level in combination with a first mapping relationship, where the first mapping relationship is a corresponding relationship between the N priority levels and the M priority levels.

Optionally, in some embodiments, if N is greater than M, in the first mapping relationship, one priority level in the second priority classes may correspond to at least one priority level in the first priority classes.

Optionally, 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.

Optionally, the first mapping relationship may be configured by a network device, or may also be configured by another terminal, or may also be predefined.

Example 3: the first device determines a corresponding priority level of the first priority level in the second priority level class according to a QoS upper layer indication (PQI) associated with a radio bearer of the first link.

In some embodiments, the priority class indicated by the PQI has the same range as the priority class included in the second priority class, in which case the corresponding priority class of the first priority class in the second priority class may be determined according to the PQI indicated by the QoS upper layer associated with the radio bearer of the first link, e.g., the priority class indicated by the PQI may be the corresponding priority class of the first priority class in the second priority class.

Example 4: and determining the corresponding priority level of the first priority level in the second priority level according to indication information of second equipment, wherein the indication information is used for indicating the corresponding priority level of the first priority level in the second priority level.

In some embodiments, the second device may be a network device, and the network device may configure, by using the indication information, a corresponding priority level of the first priority level in the second priority level class to the first device, for example, the network device may configure, by using the resource authorization of the first link, information of the corresponding priority level to the first device, where the indication information may be included in the configuration information of the resource authorization of the first link, or the network device may also configure, by using other downlink information or downlink signaling, a corresponding priority level of the first priority level in the second priority level class to the first device, which is not limited in this embodiment of the present application.

In other embodiments, the second device may be a terminal device and is denoted as a second terminal, where the second terminal may configure, by using indication information, a corresponding priority level of the first priority level in the second priority level class to the first device, for example, the second terminal may configure, by using resource authorization of the first link, information of the corresponding priority level to the first device, where the indication information may be included in configuration information of resource authorization of the first link, or the second terminal may also configure, by using other side information or side signaling, a corresponding priority level of the first priority level in the second priority level class to the first device, which is not limited in this embodiment of the present application.

It should be understood that the above embodiments are described by taking the example of corresponding the priority level of one link to the priority level of another link as an example, in other embodiments, the priority levels of both links may also be corresponding to a third priority level, for example, the corresponding priority level of the first link in the third priority level may be determined, the corresponding priority level of the second link in the third priority level may be determined, the corresponding priority levels of the first priority level and the second priority level in the third priority level may be further compared, and the link which is transmitted preferentially in the first link and the second link 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 correspond to a third priority class, the third priority class may include a priority classes, a may be a common multiple of the number of the priority classes included in the first priority class and the second priority class, for example, a is 12, and a manner of determining the corresponding priority classes in the third priority class in the priority classes in the first priority class and the second priority class may refer to the description in embodiment 1, which is not repeated 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 compare the corresponding priority levels 3X and 2Y to determine the priorities of the first link and the second link.

Therefore, in the embodiment of the present application, the first device may, under the condition that the link communications of two different networks conflict, correspond the priority levels of the two links to a unified priority classification, and further may compare the priority levels based on the unified priority classification, which is beneficial to improving the accuracy of priority determination, and further may ensure the priority transmission of the link with the high priority.
