Title:
METHOD FOR TRANSMITTING RANDOM ACCESS PREAMBLE, AND TERMINAL DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/119317
Kind Code:
A1
Abstract:
Embodiments of the present application relate to a method for transmitting a random access preamble, and a terminal device. The method comprises: performing the i-th transmission of a random access preamble, i being a positive integer greater than 1; and if the i-th transmission of the random access preamble is performed by the same wave beam as the (i-1)-th transmission, incrementing the value of a power ramping counter of the random access preamble by 1. According to the method for transmitting a random access preamble and the terminal device provided by embodiments of the present application, the terminal device can determine the power ramping counter of the random access preamble according to whether the transmission wave beam is changed.
