Abstract
Embodiments of the present invention provide methods and devices for discovery detection in device-to-device communication. A method at a first device side comprises constructing a discovery packet on each of a predetermined number of discovery cycles, wherein each discovery packet includes identical discovery information, the predetermined number being greater than 1. The method further comprises transmitting the discovery packet to at least one second device on each of the predetermined number of discovery cycles using a logically identical discovery channel. A method at a second device side comprises: receiving a discovery packet transmitted by a first device on each of a predetermined number of discovery cycles using a logically identical discovery channel; soft merging the predetermined number of discovery packets. The method further comprising detecting the discovery information in the soft merged discovery packet. Through the embodiments of the present invention, diversity gain of the soft merged discovery packet is enhanced and then detection performance regarding the discovery information is improved.
