摘要

A disclosure of the present specification provides a method for performing random access by a terminal. The method may comprise the steps of: selecting, by the terminal, a first resource among a plurality of resources for a physical random access channel (PRACH), wherein the plurality of resources exist for each numerology, and the numerology is defined by a cycle prefix (CP) length and a subcarrier spacing; and transmitting, by the terminal, the PRACH on the first resource through a first numerology when the selected first resource is for the first numerology.

說明書

The UE can determine whether to transmit data on the basis of the second configuration information. When the UE determines that data will be transmitted on the basis of the second configuration information, the UE can transmit msg3 on the basis of the second configuration information. On the other hand, when the UE determines that the second configuration information will not be used, the UE can send a request for configuration information about transmission of data suitable therefor to the eNodeB again. The configuration information requested again may be identical to or different from the first configuration information.

According to another embodiment, even when the UE selects a PRACH resource of a specific numerology and transmit a preamble, the eNodeB can designate another numerology such that msg3 is transmitted through the other numerology.

Referring to FIG. 14b, the eNodeB can designate another numerology in order to balance PRACH resources. For example, when an excessively large number of UEs are connected to the specific numerology than other numerologies and thus numerology distribution is required, the eNodeB can designate another numerology.
