Problems solved by technology

The introduction of the LBT mechanism makes it possible to send the sidelink signal only when the channel is detected to be idle. Even if there is an opportunity to send the sidelink signal, if the channel is not detected to be idle, the sidelink signal cannot be sent, that is, the sidelink signal exists. Uncertainty

Abstract

The invention relates to a communication method and device of a physical direct communication data channel and a storage medium. The communication method based on the physical direct communication data channel is applied to a terminal and comprises the steps that the physical direct communication data channel is determined, and the physical direct communication data channel comprises a plurality of sending starting positions of direct communication signals; the direct communication signals are transmitted on the unlicensed frequency band based on the plurality of transmission starting positions. According to the present disclosure, based on the plurality of start sending positions, the direct communication signals are sent on the unlicensed frequency band, so that the transmission opportunity that a physical direct connection communication data channel can be performed after LBT succeeds can be increased.

Description

technical field [0001] The present disclosure relates to the field of communication technologies, and in particular to a communication method, device and storage medium based on a physical direct communication data channel. Background technique [0002] Demands for a variety of new services and applications continue to emerge, and terminal direct communication (sidelink) has higher and higher performance requirements for transmission bandwidth, communication rate, communication delay, reliability, and scalability. Among them, the limited licensed spectrum can no longer meet the potential diverse application scenarios and requirements in the future, so it is necessary to research and design a sidelink-unlicensed technology that can be applied in the unlicensed frequency band. [0003] In an unlicensed frequency band, channel monitoring is performed based on a listen before talk (LBT) mechanism. Data can only be sent when the channel is detected to be idle. The introduction ...
