technical field

The present invention relates to the technical field of communications, and more particularly to a method and device for sending and receiving secondary link information.

Background technique

A secondary link (Sidelink, SL), also called a side link or a side link, is used for direct data transmission between terminal equipment (User Equipment, UE) without going through a network equipment. SL data transmission methods include broadcast, multicast and unicast. Both broadcast and multicast are one-to-many (one to many) transmission methods, but the concept of UEs belonging to the same UE group does not exist in the broadcast transmission method, and unicast is a one-to-one (one to one) transmission method. ) transmission method.

At present, for the two transmission methods of multicast and unicast, the receiver can send feedback information to the sender to explain the reception of the SL data object. For example, the receiver can feed back Channel State Information (CSI) to the sender. , or feed back ACK or NACK for Hybrid Automatic RepeatreQuest (HARQ). Specifically, the receiving end can send the above feedback information to the sending end in the following two ways, one is that the receiving end first sends the feedback information to a network device (such as a base station), and then the network device sends the feedback information to the sending end; the other is Yes, the sending end will feed back to the network device after receiving the feedback information from the receiving end.

However, the channel for carrying these feedback information is not clear at present. If the shared channel is used to carry these feedback information, since the shared channel can also be used to carry other information, it makes it difficult for network devices to know whether to receive the above feedback information, resulting in the above feedback information. Received incorrectly.

In the following, in conjunction with Figure 1 and Figure 2, under the two transmission modes of multicast and unicast for side link (SideLink, SL) transmission, the receiving terminal sends feedback to the sending terminal to explain the reception of the SL data object The information is described in detail in two ways.

Referring to FIG. 1 , it can be seen that, in one manner, the receiving terminal 12 first sends the feedback information to the network device (such as a base station) 13 , and then the network device 13 sends the feedback information to the sending terminal 11 .

Referring to FIG. 2 , it can be seen that, in another manner, the receiving terminal 12 first sends feedback information to the sending terminal 11 , and the sending terminal 11 sends the feedback information to the network device 13 after receiving the feedback information.

Referring to Figure 1 and Figure 2, it can be seen that no matter which method is used, the receiving terminal will send feedback information to the network device, but in the process of sending the feedback information to the network device, the channel carrying the feedback information is unclear. If the shared channel is used to carry The feedback information, because the shared channel can also be used to carry other information, makes it difficult for the network device to know whether to receive the feedback information, resulting in inaccurate reception of the feedback information.

In order to solve the above problems, the embodiment of the present invention proposes a method and device for sending and receiving secondary link information. The following describes a method for sending secondary link information provided by the embodiment of the present invention with reference to FIG. 3 .

As shown in Figure 3, a method for sending secondary link information provided by an embodiment of the present invention can be applied to a terminal device, and the method may include the following steps:

Step 301. Send target information, where the target information is used to determine feedback information for the secondary link SL.

The feedback information for the secondary link may include but not limited to at least one of hybrid automatic repeat request (Hybrid Automatic Repeat reQuest, HARQ) feedback information and channel state information (Channel State Information, CSI). Wherein, the HARQ feedback information includes ACK or NACK. And the feedback information may be carried by a shared channel. In an example, the shared channel includes a physical sidelink shared channel (Physical Sidelink Shared Channel, PSSCH).

The target information includes but is not limited to at least one of an SR sent on a preset scheduling request (Scheduing Request, SR) resource and a preset buffer status report (Buffer Status Report, BSR). That is to say, step 301 includes at least three implementation manners, wherein, the first implementation manner is to send an SR on the preset SR resource; the second implementation manner is to send a preset BSR; the third implementation manner is , sending an SR on the preset SR resource and sending a preset BSR.

The interaction process between the terminal device and the network device in the third implementation manner is described below by taking FIG. 4 as an example.

As shown in Figure 4, in the Long Term Evolution (LTE) system, the terminal device 41 sends SR and BSR to the network device as follows: ① When the terminal device 41 needs to report feedback information for SL to the network device 42, The terminal device 41 first sends an SR on the preset SR resource; (2) After receiving the SR, the network device 42 knows that the terminal device 41 has feedback information to send, and the network device 42 gives the terminal device 41 an uplink grant (UpLink grant, UL grant) to Scheduling terminal device 41 to send BSR; ③ terminal device 41 sends BSR on the uplink authorization given by network device 42; ④ network device 42 determines the feedback information that terminal device 41 needs to send according to BSR, and gives terminal device 41 uplink authorization again to schedule The terminal device 41 sends the feedback information; ⑤ The terminal device 41 sends the feedback information to the network device. It is not difficult to understand that with the SR and BSR for scheduling feedback information, network devices can achieve accurate reception of feedback information.

The method for sending secondary link information provided by the embodiment of this specification can send the target information used to determine the feedback information for SL, so that the network device can accurately receive the feedback information for SL, and the communication efficiency is improved.

The method for sending secondary link information provided by the embodiment of the present invention will be described in detail below with reference to several examples.

In a first example, the target information sent in step 301 includes an SR sent on a preset SR resource, and the SR is used to determine feedback information for SL. This example can also be understood as sending SR on a dedicated SR resource. In this way, when the network device receives the SR carried by the dedicated SR resource, it means that the information sent by the terminal device next is the feedback information for SL. Therefore, the time for receiving the feedback information for SL can be determined, and then the feedback information for SL can be accurately received at this time.

On the basis of the first example above, optionally, before performing the sending target information in step 301, the method for sending secondary link information provided by the embodiment shown in FIG. 3 may further include: Determining the preset SR resource, that is, pre-agreed in the preset protocol for the dedicated SR resource used to carry the target information (SR); or, based on the configuration information used to configure the preset SR resource, determine the The aforementioned preset SR resource means that the network device pre-configures the terminal device with a dedicated SR resource for carrying target information (SR).

Optionally, in the first example above, the preset SR resource can be either an SR (SL-SR) resource for SL, or a user-to-network universal (User to Network interface universal, Uu) SR The (Uu-SR) resource, that is, the preset SR resource may include a preset SL-SR resource or a preset Uu-SR resource, which is not limited in this embodiment of the present invention.

In the second example, the target information sent in step 301 includes the SR sent on the preset SR resource, and the SR is used to determine the feedback information for SL; wherein, the priority of the preset SR resource and the preset SL data object Corresponding to each level, the preset SL data object is the SL data object targeted by the feedback information, and the feedback information is HARQ feedback information.

This example can also be understood as sending an SR on a dedicated SR resource, and the dedicated SR resource is used to bear the SR corresponding to the SL data object of a specific priority. In this way, when the network device receives the SR carried by the dedicated SR resource, it means that the next information sent by the terminal device is not only the HARQ feedback information for SL, but also the HARQ feedback information for SL data objects with a specific priority. In the end, not only the effect of accurately receiving the HARQ feedback information for the SL at the corresponding time, but also the effect of being able to determine the priority of the SL data object for which the received HARQ feedback information is targeted, thus further improving communication effectiveness.

On the basis of the second example above, optionally, if the preset SR resources are SL-SR resources, before executing the sending target information in step 301, the secondary chain provided by the embodiment shown in FIG. 3 The method for sending road information may further include: determining the preset SR resource based on the configuration information used to configure the preset SR resource corresponding to the priority; that is, the network device pre-configures the terminal device for bearer The dedicated SL-SR resource for target information (SR), and the corresponding relationship between the dedicated SL-SR resource and the priority of the SL data object, are used for the terminal device to determine the preset SR resource carrying the target information.

Or, on the basis of the second example above, optionally, if the preset SR resources are Uu-SR resources, before executing the sending target information in step 301, the secondary The method for sending link information may also include: determining the preset SR resource based on the mapping relationship between the priority and the preset SR resource, the mapping relationship may be pre-configured by the network device, or may be stipulated by a preset agreement .

In a third example, the target information sent in step 301 includes a preset BSR, which is used to determine the feedback information for SL, and before the sending of the target information in step 301 is performed, as shown in FIG. 3 The method for sending secondary link information provided in this embodiment may further include: determining the preset BSR based on a preset protocol or based on configuration information used to configure the preset BSR.

In the first implementation manner of the third example above, a new BSR can be introduced as a preset BSR with reference to the BSR in the related art, and the preset BSR includes at least one identifier, and the at least one identifier is used for The feedback information is determined. Wherein, the at least one identifier may be at least one logical channel identifier (Logical Channel ID, LCID), a destination address identifier (Destination Index), an identifier of the feedback information itself, and the like.

For example, referring to SL BSR, truncated (Truncated) SL BSR and Uu BSR in the related art, a new BSR is introduced as a preset BSR. Specifically, the introduced preset BSR may include: a BSR for HARQ feedback, a BSR for CSI feedback, and a BSR for HARQ feedback and/or CSI feedback.

In related technologies, the BSR generally includes three parts, which are the destination address identifier (Destination Index), the logical channel group identifier (Logical Channel Group ID, LCG ID) and the amount of data to be transmitted (Buffer Size Level). The terminal device notifies the network device of the amount of data (usually in bytes) to be transmitted in all logical channels in a logical channel group based on the ProSeDestination address.

In SL BSR, the logical channel group is often divided into 4 groups, and the logical channel group identifier occupies 2 bits in the SL BSR, which is used to indicate the LCG ID corresponding to the buffer area of the terminal device; the length of the destination address identifier is configurable, and the common There are 16 groups, occupying 4 bits; the amount of data to be transmitted is arranged in descending order of the priority of the SL logical channel contained in the LCG, occupying 6 bits, and is used to specify the transmission timing interval (Transmission Timing Interval) of the SL terminal device when sending the BSR , TTI) after all MAC protocol data units (Protocol Data Unit, PDU) are generated, the radio link control (Radio Link Control, RLC) layer and packet data convergence protocol of all logical channels in the LCG corresponding to the short-distance service destination address The sum of the remaining valid data to be transmitted in the (PacketData Convergence Protocol, PDCP) layer.

Fig. 5 and Fig. 6 have shown the schematic diagram of two kinds of formats of SL BSR and truncated SL BSR respectively, and wherein Fig. 5 is the BSR format schematic diagram that the value of identification (index) is an even number, and Fig. 6 is the value of identification (index) Schematic diagram of the BSR format with an odd value. In Fig. 5 and Fig. 6, one line represents an octet (1 Oct), and N represents the maximum value of the flag.

In related technologies, the MAC layer uses a MAC Control Element (MAC Control Element, CE) to report the BSR, and the SLBSR and the truncated SL BSR use the same MAC Control Element (MAC Control Element, CE). Each MAC CE corresponds to an LCID identifier. Table 1 below lists the correspondence between LCID values and codepoints in the uplink-shared channel (UpLink-Shared Channel, UL-SCH).

Table 1

The format of the newly introduced BSR used as a preset BSR may be the same as or different from the format of the BSR in the related art (the format shown in FIG. 5 or FIG. 6 ).

For example, when the feedback information is HARQ ACK or NACK, the format of the preset BSR may be as shown in Table 2 below. In Table 2, LCIDx (ie logical channel identifier x) is used to determine HARQ feedback information for SL. The preset BSR shown in Table 2 also includes ACK/NACK destination address information, ACK/NACK data amount information, and ACK/NACK identification information.

Table 2

LCIDx Destination address information ACK/NACK data amount information Destination address information ACK/NACK identification information

For another example, when the feedback information is SCI, the format of the preset BSR may be as shown in Table 3 below. In Table 3, LCIDy was used to determine the SCI for SL. In addition, the preset BSR shown in Table 3 also includes a CSI process identifier, CSI data volume information, CSI destination address information, and CSI identifier information. It can be understood that the CSI process identifier and the CSI identifier can also be used to determine the CSI.

table 3

It can be seen from Table 2 and Table 3 that in the embodiment of the present invention, the newly introduced preset BSR may also include the destination address of the feedback information, the identifier of the feedback information, and the data volume of the feedback information at least one of the information.

It can be understood that if the target information is a preset BSR, and the preset BSR includes at least one logical channel identifier LCID used to determine the feedback information for SL, the destination address of the feedback information, the identifier of the feedback information and the When the data volume information of the feedback information is specified, the network device can accurately receive the feedback information according to the preset BSR.

In the second implementation manner of the third example above, a preset number of bits may be added to the BSR in the related art to indicate that at least one identifier in the BSR may also be used to determine feedback information for SL, To obtain a preset BSR, wherein the at least one identifier may be at least one LCID, a destination address identifier, an identifier of the feedback information itself, and so on. Optionally, in the second implementation manner, the preset BSR may further include a destination address of the feedback information, an identifier of the feedback information, and data volume information of the feedback information.

For example, a preset number of bits are added to SL BSR, truncated (Truncated) SL BSR, and Uu BSR in the related art to indicate that at least one LCID in the BSR can also be used to determine feedback information for SL, to Get element and BSR. The BSR after adding a preset number of bits may be as shown in Table 4.

Table 4

LCIDz BSR information of logical channels with different destination addresses Destination address information ACK/NACK data amount information Destination address information ACK/NACK data amount information

In Table 4, "BSR information of logical channels with different destination addresses" is the information contained in the BSR in the related art, and "LCIDz", "Destination address information" and "ACK/NACK data volume information" are the increased preset numbers The information contained in the bits, the information contained in the preset number of bits can be used to determine the feedback information for SL.

It can be understood that since the preset BSR shown in Table 4 also includes at least one logical channel identifier LCID for determining the feedback information for SL, the destination address of the feedback information, and the data amount information of the feedback information, therefore, After the network device receives the preset BSR shown in Table 4, the purpose of accurately receiving the feedback information for the SL can also be achieved based on the preset BSR.
