Example 1

In this example, a direct communication transmitting terminal is taken as an example of a communication device for determining a processing manner of SLRB repeat transmission, and referring to fig. 7, an interaction procedure of the direct communication transmitting terminal, the direct communication receiving terminal, and a network side device accessed by the direct communication transmitting terminal is as follows:

in step S701, when the direct communication transmitting terminal determines to perform SLRB transmission, the processing method of SLRB repeated transmission is performed.

That is, the direct communication transmitting terminal performs processing means for determining whether to activate or deactivate the SLRB repeat transmission for the SLRB by itself when the direct communication transmitting terminal performs the SLRB transmission.

In step S702, the direct communication transmitting terminal indicates the determined processing manner to its corresponding direct communication receiving terminal through the control signaling.

The purpose of this step is to enable the direct communication receiving terminal to reasonably perform SLRB reception through the logical channel corresponding to the activated RLC entity.

Alternatively, after the above step S702 is performed, step S703 may be performed.

In step S703, after the direct communication receiving terminal receives the instructed processing manner, the processing manner is instructed to the network side device to which the direct communication receiving terminal is connected, so that the network side device to which the direct communication receiving terminal is connected correctly receives the SL BSR (Buffer Status Reporting, buffer status report) and the SL resource allocation for the bidirectional SLRB in which the reverse (i.e., the transmission direction from the direct communication receiving terminal to the direct communication transmitting terminal) repeated transmission is activated.

Correspondingly, the network side device to which the direct communication receiving terminal accesses may perform the following step S7031.

Optionally, if the direct communication interface has the concept of the main RLC entity, the control signaling also needs to carry indication information of the main RLC entity activated by the SLRB repeated transmission.

In step S7041, the network side device to which the direct communication transmitting terminal accesses performs SL BSR reception according to the instructed processing method.

It should be noted that, the network side device accessed by the direct communication transmitting terminal and the network side device accessed by the direct communication receiving terminal may be the same device or may be different devices.

Example 2

In this example, a direct communication receiving terminal is taken as an example of a communication device for determining a processing manner of SLRB repeat transmission, and referring to fig. 8, an interaction procedure of a direct communication transmitting terminal, a direct communication receiving terminal, and a network side device accessed by the direct communication transmitting terminal is as follows:

In step S801, the direct communication receiving terminal determines a processing manner of SLRB repeated transmission.

That is, the direct communication receiving terminal is used as an execution body for judging whether to activate or deactivate the SLRB repeat transmission with respect to the SLRB, and determines a processing manner of the SLRB repeat transmission when the direct communication transmitting terminal performs the SLRB transmission thereto, the processing manner including activating or deactivating the SLRB repeat transmission.

Step S802, the direct communication receiving terminal indicates the determined processing mode to the direct communication transmitting terminal through the control signaling.

The purpose of this step is to enable the direct communication transmitting terminal to clearly identify the RLC entity activated for the SLRB, and to perform SLRB transmission using the logical channel corresponding to the activated RLC entity.

Further, the direct communication receiving terminal may perform the following step S803.

In step S803, the direct communication receiving terminal performs SLRB related control PDU transmission according to the determined processing method.

If the control signaling contains the indication information of the main RLC entity or the indication information of the RLC entity transmitted by the control PDU, in this step, the direct communication receiving terminal may perform the transmission of the SLRB related control PDU (such as a status report PDU) through the main RLC entity corresponding to the active main leg.

Further, after the direct communication transmitting terminal receives the instructed processing manner, the following step S804 may be executed.

Step S804, the direct communication transmitting terminal indicates the determined processing mode to the network side device accessed by the direct communication transmitting terminal through the control signaling.

Further, after the processing manner of receiving the instruction, the network side device accessed by the direct communication transmitting terminal executes the following step S805.

Step S805, the network side equipment accessed by the direct communication sending terminal receives the SL BSR according to the indicated processing mode.

If the control signaling carries indication information of the main RLC entity activated by SLRB repeated transmission or indication information of the RLC entity transmitted by the control PDU, network side equipment accessed by the direct communication sending terminal can reasonably receive the SL BSR and judge that only the main RLC entity or the RLC entity transmitted by the control PDU contains the PDCP control PDU and determine the data quantity of the PDCP control PDU.

Example 3

For different resource allocation modes, the execution bodies of the processing modes for determining the SLRB repeat transmission are different, and the following modes are provided in this example:

1) When the resource allocation mode corresponding to the SLRB is the resource allocation mode of network scheduling, the network side equipment accessed by the direct communication sending terminal or the network side equipment accessed by the direct communication receiving terminal is used as the execution main body;

2) When the resource allocation mode corresponding to the SLRB is a resource allocation mode selected by the terminal, the direct communication transmitting terminal or the direct communication receiving terminal is used as the execution subject.

For the manner of indicating to activate or deactivate the SLRB repeat transmission when the execution body is the direct communication transmitting terminal or the direct communication receiving terminal in the terminal-selected resource allocation mode, see example 1 and example 2 described above, and will not be repeated here.

The following describes a manner of instructing to activate or deactivate the SLRB retransmission, with respect to the network side device to which the direct communication transmitting terminal accesses or the network side device to which the direct communication receiving terminal accesses as an execution body.

Referring to fig. 9, the description is made here with the network side device accessed by the direct communication transmitting terminal as the execution subject, and the interaction procedure of the direct communication transmitting terminal, the direct communication receiving terminal, and the network side device accessed by the direct communication transmitting terminal is as follows:

Step S901, a network side device accessed by a direct communication sending terminal determines a processing mode of SLRB repeated transmission.

The network side equipment accessed by the direct communication sending terminal determines the processing mode of SLRB repeated transmission by itself, wherein the processing mode comprises the steps of activating SLRB repeated transmission or deactivating SLRB repeated transmission; the SLRB may be an SLRB for allocating resources using a resource allocation pattern of network scheduling, or the resource allocation pattern of the SLRB may not be limited.

In step S902, the direct communication transmitting terminal instructs the direct communication transmitting terminal of the determined processing method through the control signaling.

The purpose of this step is to enable the direct communication transmitting terminal to explicitly repeat transmission of the corresponding active RLC entity for the SLRB, so that a reasonable data transmission is performed on the direct communication interface.

Alternatively, after performing the above step S902, the direct communication transmission terminal may perform step S903.

In step S903, after the direct communication transmitting terminal receives the instructed processing method, the processing method is instructed to the direct communication receiving terminal by the control signaling.

The purpose of this step is to enable the direct communication receiving terminal to reasonably perform SLRB reception through the logical channel corresponding to the activated RLC entity, and also enable the direct communication receiving terminal to perform feedback of the control PDU corresponding to the SLRB through the RLC entity activated by the SLRB or the main RLC entity or the RLC entity capable of performing control PDU transmission.

The control signaling used in the processing manner in the embodiment of the present application may be MAC layer signaling, where the MAC layer signaling may be a new MAC CE, and a new LCID needs to be introduced for the MAC CE.

When using MAC CE as control signaling, the MAC CE signaling may be used, but is not limited to, to indicate any of the following information:

1) One MAC CE signaling indicates indication information of a processing manner of repeated transmission of one SLRB.

Here, the MAC CE includes only the Source address, the Destination address, and the SLRB identifier, for example, please refer to fig. 10, wherein SRC is the Source address (Source L2 ID), DST is the Destination address (Destination L2 ID), R is the reserved bit, and D is the indication of the processing mode; a value of 1 for D indicates that SLRB repeat transmission is activated, and a value of 0 for D indicates that SLRB repeat transmission is deactivated.
