Abstract
Disclosed is a device discovery method, comprising: a terminal device sending a target sequence on a first time-frequency resource by means of a first antenna port, wherein the target sequence is used for implementing D2D discovery; and the terminal device detecting, while sending the target sequence, a first sequence on the first time-frequency resource by means of a second antenna port, wherein the first sequence and the target sequence are sequences, having autocorrelation and cross-correlation attributes, in a first sequence group. Also disclosed are a terminal device and a storage medium.

A device discovery method, comprising:
- sending, by a terminal device, a target sequence on a first time-frequency resource via a first antenna port, wherein the target sequence is used for implementing Device to Device (D2D) discovery;
- and
- detecting, by the terminal device, a first sequence on the first time-frequency resource via a second antenna port while sending the target sequence, wherein the first sequence and the target sequence are sequences having autocorrelation and cross-correlation attributes in a first sequence group.
A terminal device, comprising:
- a processor and a memory for storing a computer program capable of running on the processor;
- wherein the processor is configured to:
- send a target sequence on a first time-frequency resource via a first antenna port, wherein the target sequence is used for implementing Device to Device (D2D) discovery;
- and
- detect a first sequence on the first time-frequency resource via a second antenna port while sending the target sequence, wherein the first sequence and the target sequence are sequences having autocorrelation and cross-correlation attributes in a first sequence group.
