Communications method and apparatus

A communications method for a sidelink communication, comprising:

• generating, by a network device, first signaling comprising down link control information (DCI) in a physical downlink control channel (PDCCH) for a first terminal device, wherein the first signaling is used by the user terminal to schedule transmission of sidelink feedback control information, wherein the first signaling indicates resources for the first terminal to use for sending HARQ ACK information received from another terminal via sidelink communications back to the network device;
• and
• the sidelink feedback control information comprises at least one of channel state information, a receiving response, or a scheduling request and wherein the second signaling is for scheduling transmission of data and/or control signaling;
• and
• sending, by the network device or a second terminal device, the first signaling to the first terminal device to enable the first terminal device to produce data and/or control signaling to the second terminal device over a side link and to enable the first terminal device to report HARQ ACK information received from the second terminal device.

A communications apparatus, comprising:

• a memory storage comprising instructions;
• and
• one or more processors in communication with the memory storage, wherein the execution of the instructions by the one or more processors causes the apparatus to:
• receive first signaling from a network device or a second terminal device wherein the first signaling is used to schedule transmission of the sidelink feedback control information and comprises down link control information (DCI) from a network device in a physical downlink control channel (PDCCH) which indicates:
• resources for the first terminal to use for sidelink control and data;
• and
• resources for the first terminal to use for sending sidelink feedback control information received from another terminal via sidelink communications back to the network device, the sidelink feedback control information comprising at least one of HARQ ACK information,
• channel state information, a receiving response, or a scheduling request;
• transmit the data and/or control signaling via the sidelink.

• and the sidelink feedback control information comprises at least one of channel state information, a response to a received message, or a scheduling request;
• and
• send the first signaling to the first terminal device to enable the first terminal device to report HARQ ACK information received from a second terminal device over a sidelink.
