FIELD: wireless communication.
SUBSTANCE: invention relates to wireless communication and specifically to a method and a device for direct communication. Achievement of the result is provided by the proposed method of communication along the direct communication line performed by the first terminal. Communication method involves receiving a forward link communication resource scheduled by a network device and transmitting indication information configured to indicate the state of use of said forward link communication resource. Indication information is configured to indicate non-use of said forward link communication resource in response to determination that the second terminal, which is in an active state and communicates over the forward link with the first terminal, is absent. In response to the network device configuring the physical uplink control channel (PUCCH) for the forward link communication resource and in response to performing retransmission based on the communication resource of the forward link, transmitting feedback with negative acknowledgment of reception of a hybrid automatic retransmission request (HARQ) for transmitting data based on said communication resource of the forward link.
EFFECT: possibility to avoid erroneous scheduling of communication resource of direct communication line and irrational consumption of resources.
