The processing method includes activating the SLRB repeated transmission or deactivating the SLRB repeated transmission; the above-mentioned SLRB can be allocated using the resource allocation mode of network scheduling. The SLRB of the resource may not limit the resource allocation mode of the SLRB.

Step S902: The direct communication sending terminal indicates the determined processing mode to the direct communication sending terminal through the control signaling.

The purpose of this step is to allow the direct communication sending terminal to clearly repeat the corresponding activated RLC entity for the SLRB, so as to perform reasonable data transmission on the direct communication interface.

Optionally, after performing step S902, the direct communication sending terminal may perform step S903.

Step S903: After the direct communication sending terminal receives the indicated processing mode, the processing mode is indicated to the direct communication receiving terminal through the control signaling.
