Title:
METHOD AND DEVICE FOR TRANSMITTING PRACH SIGNALS IN UNAUTHORIZED SPECTRUM
Document Type and Number:
WIPO Patent Application WO/2017/133368
Kind Code:
A1
Abstract:
Disclosed in the present application are a method and a device for transmitting PRACH signals in an unauthorized spectrum, used for enhancing channel access for a PRACH signal. The method comprises: before transmitting each candidate resource as configured in resources, a terminal performs LBT detection according to configuration information of a transmission resource for transmitting PRACH signals until a current channel is detected to be idle; and after detecting that the current channel is idle, the terminal transmits a PRACH signal on the corresponding candidate resource. In the present application, a plurality of candidate resources are configured in a transmission resource for transmitting PRACH signals, such that the terminal may transmit the PRACH signals on the corresponding candidate resource when it is detected that the current channel is idle before any candidate resource, thereby improving transmission probability for PRACH signals and enhancing channel access for PRACH signals.
