Description

FIELD OF TECHNOLOGY TO WHICH THE INVENTION RELATES

The present invention relates to the field of communications and, in particular, to a method and a terminal device for transmitting direct connection data.

BACKGROUND OF THE INVENTION

The vehicle-environment communication system is a direct connection (Sidelink, SL) transmission technology based on long-term evolution (Long Term Evolution, LTE) and device-to-device (D2D) communication. Unlike conventional LTE systems in which communication data is received or transmitted through a base station, the vehicle environment communication system uses direct device-to-device communication and thus has higher spectral efficiency and lower transmission delay.

In vehicle-to-everything (V2X) technology for NR systems, there may be many transmission modes such as unicast, multicast, and broadcast. With unicast transmission, there is only one specific terminal device on the receiving side. In multicasting, a communication group is established, and when one of the terminal devices in the group transmits data, for example, a terminal device that is the main member of the group with the functions of coordination, control, distribution, control, and the like. resources in the group is transmitting data, the other terminal devices in the group are receiving terminals. In this case, unicast can be considered as a special kind of multicast, that is, there are only two terminal devices in the group. In broadcast transmission, a terminal device transmits data and all other terminal devices are receiving terminals.

Since the terminal device may participate in more than one group communication or broadcast communication, a conflict will occur when the terminal device needs to receive data in a multicast communication at the moment, and also needs to transmit data in another group communication or broadcast communication at the moment.

In one implementation, the communication system 100 may also include other network entities such as a network controller, a mobility management entity, or the like, which is not limited in embodiments of the present invention.

It should be understood that in embodiments of the present invention, a device with a network/system communication function may be referred to as a communication device. Taking the communication system 100 shown in FIG. 1, by way of example, the communication device may include a network device 110 and a terminal device 120 that has a communication function, and the network device 110 and the terminal device 120 may be specific devices described above that will not be re-described herein. The communication device may also include other devices such as other network entities such as a network controller, a mobility management node located in the communication system 100, which is not limited in the embodiments of the present invention.

It should be understood that the terms "system" and "network" are often used interchangeably throughout this document. The expression "and/or" in this document is only a description of the relationship of the relationship of related objects and indicates that there can be three relationships. For example, "A and/or B" can mean three cases: A exists separately, both A and B exist, and B exists separately. In addition, the symbol "/" in this document generally indicates that the related objects before and after this symbol are related by the relationship "or".

V2X is standardized in 3GPP Release 14 (Rel-14), and two transmission modes are defined: Mode 3 and Mode 4. FIG. 2 is a schematic representation of two transmission modes in a V2X system according to an embodiment of the present invention.

As shown in FIG. 2, mode 3 on the left indicates that: the transmission resources of the vehicle terminal are allocated by the base station via a downlink (DL), and the vehicle terminal transmits data on a direct connection according to the resources allocated by the base station; the base station may allocate resources for a single transmission or semi-static transmission resources per terminal.

As shown in FIG. 2, mode 4 on the right indicates that: the terminal on the vehicle receives the recognition and reservation transmission modes. The terminal on the vehicle obtains an available set of transmission resources from the resource pool through recognition, and the terminal randomly selects a resource from the set for data transmission. Since the services in the V2X system have periodic characteristics, the terminal usually adopts a semi-static transmission mode. That is, after the terminal selects a transmission resource, it will continuously use the resource in a plurality of transmission cycles to reduce the chance of resource reselection and resource conflict. The terminal will carry resource reservation information for the next transmission in the control information of this transmission to allow other terminals to determine whether the resource is reserved and used by the user by detecting the user's control information, thereby achieving the goal of reducing resource contention.

Similar to the above, the NR-V2X system also provides a plurality of transmission modes, which may include, for example, mode 1 and mode 2. In mode 1, the network device allocates transmission resources to terminals, which is similar to mode 3 in LTE-V2X, and the terminal devices use the transmission resources allocated by the network device, while in mode 2, the terminal device selects the transmission resources. Mode 2 further includes several sub-modes (mode), which may specifically include, for example, the following.

(1) Mode 2a: similar to the above mode 4 in LTE-V2X, where the terminal device selects transmission resources autonomously. For example, the terminal autonomously selects resources from a pre-configured or network-configured pool of resources, either by random selection or by recognition.

(2) Mode 2b: the terminal assists other terminals in resource selection. For example, the first terminal transmits the side information to the second terminal, and the terminal device receiving the side information can determine the transmission resource according to the side information, where the side information contains one or more pieces of the following information: available time-frequency resource information, available information about the transmission resource set, channel measurement information, and channel quality information such as Channel State Information (CSI), Channel Quality Indicator (CQI), Precoding Matrix Indicator (PMI) , Rank indication (RI), Reference Signal Receiving Power (RSRP), Reference Signal Receiving Quality (RSRQ), Received Signal Strength Indicator (RSSI), interference and traffic information th losses, etc.

(3) Mode 2c: The terminal device selects a resource from its configured transmission resources. For example, a network device may configure transmission resources for each terminal in a group of terminal devices, where the transmission resources for each terminal device may be the same or different, and when any of the terminals has direct connection data for transmission, the transmission resources configured by the network device may be used for data transmission. For example, when a network device configures the same resources for each terminal device in a group of terminal devices, the terminal device to which direct connection data needs to be transmitted may select an available resource among the configured resources by recognition or otherwise; or the network device may also configure different transmission resources for each terminal device in the terminal device group, and the terminal device to which direct connection data needs to be transmitted may select an available resource from the resources configured for it.

(4) Mode 2d: the first terminal apparatus allocates transmission resources to the second terminal apparatus. For example, for a plurality of terminal devices in a group line, when the first terminal device is a group member of the specified line group, and the second terminal device is a member of the group of the specified group, the first terminal device can directly assign a time frequency resource to the second terminal device to transmit direct connections.

In addition, NR V2X can also have a variety of transmission modes, such as Unicast, Groupcast, and Broadcast. In unicast, there is only one specific terminal device on the receiving side. In a multicast, a communication group is established, and when a terminal device in the group transmits data, for example, a terminal device that is the head of the group with the functions of coordination, control, distribution, control, and the like. resources in the group is transmitting data, all other terminal devices in the group may be target receiving terminals. Unicast can be considered as a special kind of multicast, that is, a multicast with only two terminal devices in the group is unicast. In a broadcast, a terminal device transmits data and all other terminal devices are target receiving terminals.

In a multicast (or unicast) transmission, the head of the group may allocate transmission resources to the members of the group. For example, the terminal device may apply the above resource allocation method, such as the 2d mode described above, and the terminal device may participate in one or more group communications. For example, if we take Fig. 3 as an example, in FIG. 3 is a schematic representation of two multicasts according to an embodiment of the present invention. As shown in FIG. 3, UE1, UE2, and UE3 form a first communication group, where UE1 is the group leader, and UE3, UE4, and UE5 form a second communication group, where UE5 is the group leader. In this case, UE3 is in two communication groups at the same time, wherein in the first group, UE1 may allocate transmission resources to UE3, and in the second group, UE5 may allocate transmission resources to UE3. When UE1 instructs UE3 to receive data now and UE5 commands UE3 to transmit data now, what is UE3 doing now?

Or, UE3 multicasts in the first group, and UE3 needs to simultaneously perform broadcasting, where in multicasting, UE1 allocates transmission resources to UE3, while in broadcasting, UE3 selects transmission resources autonomously, for example, by using mode 2a. When UE1 instructs UE3 to receive data while UE3 selects that time to transmit data, how does UE3 act?

Therefore, an embodiment of the present invention provides a direct connection data transmission method that can resolve conflict that a terminal transmits and receives data at the same time.

In FIG. 4 is a schematic representation of a method 200 for transmitting direct connection data according to an embodiment of the present invention, and the method 200 may be performed by any of the terminal devices. In particular, the terminal device may be in direct connection with other terminal devices, for example, the terminal device may be any of the terminal devices shown in FIG. 1 in FIG. 2 or in FIG. 3. As shown in FIG. 4, the method 200 includes: in step S210, receiving the first direct connection transmission channel or transmitting the second direct connection transmission channel on the transmission target resource by the terminal device, according to the first rule, when the terminal device determines, according to the first configuration information, what to receive. the first direct connection bearer on the transmission target resource, and determines, according to the second configuration information, that the second direct connection bearer is to be transmitted on the transmission target resource.

It should be understood that up to step S210, the method 200 also includes: determining by the terminal device, in accordance with the first configuration information, that the first transmission channel of the direct connection on the transmission target resource should be received. Moreover, the method 200 further includes: determining by the terminal device in accordance with the second configuration information that the second direct connection transmission channel should be transmitted on the transmission target resource. That is, both the data to be received and the data to be transmitted of the direct connection are configured on the same transmission target resource, and then a resource conflict will occur.

In embodiments of the present invention, the first direct connection bearer and the second direct connect bearer refer to direct connection communication between a terminal device and another terminal device. Specifically, receiving by the terminal device the first direct connection transmission channel on the transmission target includes: receiving by the terminal device data transmitted by another terminal device via the first direct connection transmission channel using the transmission target resource; and transmitting, by the terminal device, the second direct connection transmission channel on the transmission target resource includes: transmitting data by the terminal device to another terminal device via the second direct connection transmission channel.

In one embodiment, the first direct connection transmission channel or the second direct connection transmission channel may be any of the following channels: Physical Sidelink Control Channel (PSCCH), Physical Sidelink Shared Channel (PSSCH) ), a Physical Sidelink Broadcast Channel (PSBCH), and a Physical Sidelink Feedback Channel (PSFCH).

In one embodiment, the method 200 according to the present invention is applicable to direct connection transmission channels and is also applicable to direct connection signal transmission. For example, the first direct connection transmission channel or the second direct connection transmission channel may also be replaced by a Sidelink Synchronization Signal (SLSS), where SLSS may include a Sidelink-Primary synchronization signal (S-PSS) and /or secondary direct connection synchronization signal (Sidelink-Secondary synchronization signal, S-SSS), and embodiments of the present invention are not limited to them.

It should be understood that the target transmission resource in embodiments of the present invention may be a time domain resource, or may also be a time frequency resource. Specifically, when the transmission target resource is a time domain resource, the terminal device determines, according to the first configuration information, that the first direct connection transmission channel is to be received using the time domain resource, and it also simultaneously transmits the second direct connection transmission channel, and the frequency domain resources corresponding to the first direct connection transmission channel and the second direct connection transmission channel may be the same or may be different.

In embodiments of the present invention, when the terminal device determines, according to the first configuration information and the second configuration information, that it needs to receive the first direct connection transmission channel and transmit the second direct connection transmission channel on the same transmission resource, the terminal device may choose, according to the first rule, to receive the first direct connection transmission channel or transmit the second direct connection transmission channel on the transmission target resource. Here, the first rule may be pre-configured, for example, may be specified in the protocol; or the first rule may also be configured for the terminal device by the network device, and embodiments of the present invention are not limited to this.

It should be understood that the first rule may include many embodiments. The first rule will be illustrated and detailed below in conjunction with several specific embodiments.

Embodiment 1

The first rule is that: the terminal device receives the first direct connection transmission channel or transmits the second direct connection transmission channel on the transmission target according to the result of comparing the first data parameter information to be received on the first direct connection transmission channel and the second information about the data parameters to be transmitted on the second transmission channel of the direct connection.

Specifically, the terminal device may receive the first information about the data parameters to be received on the first direct connection transmission channel, and may also receive the second information about the data parameters to be transmitted on the second direct connection transmission channel. Here, the first parameter information may be received by the terminal device from the other terminal device, and the other terminal device is a terminal device to transmit the first direct connection transmission channel to the terminal device.

The terminal device selects, according to the result of comparing the first parameter information and the second parameter information, to receive the first direct connection transmission channel or transmit the second direct connection transmission channel on this transmission target resource. Here, the result of comparing the first parameter information and the second parameter information refers to the specific parameters included therein.

In one embodiment, as an embodiment, when the first parameter information is priority information of data to be received and the second parameter information is priority information of data to be transmitted, then the terminal device can select, according to the comparison result priority information, receiving the first direct connection transmission channel, or transmitting the second direct connection transmission channel on the transmission target resource. Specifically, the terminal device receives the first direct connection transmission channel on the transmission target resource when the priority of the data to be received is higher than the priority of the data to be transmitted; or the terminal apparatus transmits the second direct connection transmission channel on the transmission target resource when the priority of the data to be received is lower than the priority of the data to be transmitted.

In one embodiment, information about the priorities of data to be received and/or data to be transmitted may be carried in Sidelink Control Information (SCI). For example, priority is indicated by the priority value for each ProSe packet (ProSe Per-Packet Priority, PPPP), and a lower PPPP value indicates a higher priority level, however, embodiments of the present invention are not limited to this.

For example, when the PPPP value of the data to be received on the first direct connection transmission channel is 1, and the PPPP value of the data to be transmitted on the second direct connection transmission channel is 3, since a lower PPPP value indicates a higher priority, then the data priority to be received is higher than the priority of the data to be transmitted, and hence the terminal device receives the first direct connection transmission channel on the target resource.

In one implementation as an embodiment, the first parameter information is delay information of data to be received, and the second parameter information is delay information of data to be transmitted; then the terminal device can compare the delays according to the delay requirements of the data to be received and the data to be transmitted, and thus select the reception of the first direct connection transmission channel or the transmission of the second direct connection transmission channel on the target transmission resource. Specifically, the terminal device receives the first direct connection transmission channel on the transmission target resource when the delay of the data to be received is less than the delay of the data to be transmitted; or the terminal apparatus transmits the second direct connection transmission channel on the transmission target resource when the delay of the data to be received is greater than the delay of the data to be transmitted.

For example, the delay of the data to be received on the first direct connection transmission channel is required to be 10 mm, and the delay of the data to be transmitted on the second direct connection transmission channel is required to be 100 ms; the delay of the data to be received is smaller than the delay of the data to be transmitted, and a shorter delay indicates a more urgent service, and hence the terminal device receives the first direct connection transmission channel on the target resource.

In one implementation as an embodiment, the first parameter information is information about the reliability of data to be received, and the second information about the parameters is information about the reliability of data to be transmitted; then the terminal device can compare the reliability in accordance with the reliability requirements of the data to be received and the data to be transmitted, and then select the reception of the first direct connection transmission channel or the transmission of the second direct connection transmission channel on the transmission target resource. Specifically, the terminal device receives the first direct connection transmission channel on the transmission target resource when the reliability of the data to be received is greater than the reliability of the data to be transmitted; or the terminal apparatus transmits the second direct connection transmission channel on the transmission target resource when the reliability of the data to be received is less than the reliability of the data to be transmitted.

For example, the reliability of the data to be received on the first direct connection transmission channel is required to be 90%, and the reliability of the data to be transmitted on the second direct connection transmission channel is required to be 99%; the required reliability of the data to be received is lower than the required reliability of the data to be transmitted, and hence the terminal apparatus transmits the second direct connection transmission channel on the target resource.

Optionally, the first parameter information and the second parameter information may also be other parameter information. For example, the first parameter information is the Quality of Service (QoS) information of the data to be received, and the second parameter is the QoS information of the data to be transmitted, and the terminal device selects the reception or transmission of data on the transmission target resource according to with QoS levels of data to be received and data to be transmitted. For brevity, they are not listed in this document.

In one embodiment, each of the above embodiments is exemplified by each of the first parameter information and the second parameter information, including one kind of information; however, the first parameter information and the second parameter information may also include a plurality of kinds of information, and an exhaustive judgment can be made using the plurality of kinds of information. For example, both the first parameter information and the second parameter information include priority information and delay information, and the priorities may be compared first; when the priority in the first parameter information is not equal to the priority in the second parameter information, the selection can be made according to the above result of the comparison of priorities for receiving the first direct connection transmission channel or transmitting the second direct connection transmission channel on the transmission target resource; when the priority in the first parameter information is equal to the priority in the second parameter information, then the delay information in the first parameter information and the delay information in the second parameter information may be compared, and a selection is made, according to the result of comparing the delay information, of receiving the first direct connection transmission channel or the transmission of the second direct connection transmission channel on the target transmission resource. Thus, when the first parameter information and the second parameter information include a plurality of parameters, they can be used in combination, and embodiments of the present invention are not limited to this.

Embodiment 2

The first rule is that: the terminal device receives the first direct connection transmission channel on the transmission target resource when the transmission type priority of the first direct connection transmission channel is higher than the transmission type priority of the second direct connection transmission channel; or the terminal apparatus transmits the second direct connection bearer on the transmission target resource when the transmission type priority of the first direct connect bearer is lower than the bearer type priority of the second direct connect bearer.

In an embodiment of the present invention, the transmission type of the first direct connection transmission channel or the second direct connection transmission channel may be unicast, multicast or broadcast, where unicast may also be considered as a special kind of multicast. For purposes of illustration, unicast, referred to below, refers to direct-connect communication between two terminal devices, while multicast refers to direct-connect communication among three or more terminal devices.

In an embodiment of the present invention, the transmission type priority of a direct connection transmission channel may be set according to practical applications, or defined in a protocol, or configured according to a network. For example, the unicast and multicast priorities can generally be set to be higher than the broadcast priorities; and the unicast and multicast priorities may be equal or unequal, or the unicast priority and the multicast priority may be judged according to other conditions; or it can also be set that the unicast priority is higher or lower than the multicast priority, however, embodiments of the present invention are not limited to this.

Embodiment 3

The first rule is that: the terminal device receives the first direct connection transmission channel or transmits the second direct connection transmission channel on the transmission target resource according to the distribution mode of the transmission target resource in the first configuration information and the second configuration information.

It should be understood that there may be different modes of allocation of the target transmission resource of the terminal device, such as the aforementioned mode 1 and mode 2 in the NR system, where mode 2 may also include various sub-modes, such as modes 2a-2d. The transmission target resource mode determined by the terminal device according to the first configuration information may be different from the transmission target resource mode determined according to the second configuration information, so reception of the first direct connection transmission channel or transmission of the second direct connection transmission channel may be selected. on the target transmission resource in accordance with the allocation mode of the target transmission resource.

In one implementation, in terms of the various entities that allocate that transmission target resource, the allocation modes of the transmission target resource can be divided into network device allocated, other terminal device allocated, and terminal device itself allocated. Accordingly, the allocation modes of the transmission target resource in the first configuration information or the second configuration information may be any of the following: allocated by a network device, allocated by another terminal device, and distributed by a terminal device.

In particular, the distribution mode of the transmission target resource in the first configuration information or the second configuration information "distributed by the network device" is that: the network device transmits the first configuration information or the second configuration information to the terminal device, where the first information about configuration or the second configuration information may be scheduling information or resource pool configuration information transmitted by the network device. That is, the transmission target resource is allocated by the network device to the terminal device by the first configuration information for receiving the first direct connection transmission channel, or the transmission target resource is allocated by the network device to the terminal device by the second configuration information for transmitting the second direct connection transmission channel.

Similarly, the distribution mode of the transmission target in the first configuration information or the second configuration information "allocated by another terminal device" is that: the other terminal device transmits the first configuration information or the second configuration information to the terminal device, where the other terminal device device is a terminal device other than a terminal device, and other terminal device may refer to any terminal device other than a terminal device. That is, the transmission target resource is allocated by the other network device to the terminal device by the first configuration information for receiving the first direct connection transmission channel, or the transmission target resource is allocated by the other terminal device to the terminal device by the second configuration information for transmitting the second direct connection transmission channel.

The distribution mode of the transmission target resource in the first configuration information or the second configuration information "allocated by the terminal device itself" is that: the first configuration information or the second configuration information is determined by the terminal device itself, that is, the terminal device determines the first information about configuration and determines that the target transmission resource is used to receive the first transmission channel of the direct connection; or the terminal device determines the second configuration information and determines that the transmission target resource is used to transmit the second configuration information, where the first configuration information or the second configuration information may come from an upper layer of the terminal device, such as an application layer, or a control layer. radio link, or the media access control layer.

It should be understood that different resource allocation modes may correspond to different priorities. For example, as a general rule, the "network device allocated" resource allocation mode can be set to have the highest priority. For example, the priority of the above mode 1 is greater than the priority of mode 2, provided that the terminal device applies mode 1 to determine the reception of the first direct connection transmission channel on the transmission target according to the first configuration information, and applies mode 2 (any of the above modes 2, for example, mode 2a in mode 2) to determine the transmission of the second direct connection transmission channel on the transmission target according to the second configuration information, since the priority of mode 1 is greater than the priority of mode 2, and the terminal device selects to receive the first direct connection transmission channel on the transfer destination. In addition, the priorities of "allocated by another terminal device" and "allocated by the terminal device itself" may be the same or may also be different. For example, the priority of the resource allocation mode of another terminal device allocating the resource may also be set higher than the priority of the resource allocation mode of the resource allocating terminal device itself, for example, the priority of the above mode 2d or mode 2b is higher than the priority of mode 2a; however, embodiments of the present invention are not limited to this.

For example, when the transmission target resource in the first configuration information is allocated by the network device and the transmission target resource in the second configuration information is allocated by another terminal device or allocated by the terminal device itself, the terminal device can receive the first direct connection transmission channel in priority, that is, receive the first channel transferring the direct connection on the target transfer resource; or, when the transmission target resource in the first configuration information is allocated by another terminal device or allocated by the terminal device itself, and the transmission target resource in the second configuration information is allocated by the network device, the terminal device may transmit the second direct connection transmission channel in priority, that is, transmit the second channel direct connection transfers on the target transfer resource.

In the embodiments of the present invention, it is assumed that the terminal device needs to receive the first direct connection bearer transmitted by the first terminal device on the target transmission resource, and transmit the second direct connect bearer to the second terminal device, since a collision occurs, and as a result, the terminal device decides, that the first direct connection bearer should be received or the second direct connect bearer should be transmitted on the target transmission resource according to the first rule.
