Title:
COMMUNICATION METHOD, COMMUNICATION DEVICE, AND NETWORK DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/153357
Kind Code:
A1
Abstract:
The present application provides a communication method, a communication device, and a network device. The method comprises: a terminal device determining a random access preamble, wherein the random access preamble comprises six symbol groups; the terminal device further determining, according to random access configuration information and a preset rule, the frequency position of the random access preamble, wherein a frequency-hopping interval between the first symbol group and the second symbol group and a frequency-hopping interval between the fifth symbol group and the sixth symbol group are equal and are both a first interval, a frequency-hopping interval between the second symbol group and the third symbol group and a frequency-hopping interval between the fourth symbol group and the fifth symbol group are equal and are both a second interval, and a frequency-hopping interval between the third symbol group and the fourth symbol group is a third interval; and the terminal device transmitting, according to the frequency position, the random access preamble. In the communication method of the present application, a terminal device can transmit a random access preamble by determining the frequency-hopping pattern of the random access preamble, so as to perform random access.
