A METHOD AND A USER EQUIPMENT FOR TRANSMITTING A SIGNAL, AND A METHOD AND A BASE STATION FOR RECEIVING A SIGNAL

摘要

A method for transmitting or receiving an uplink signal is disclosed. If a user equipment is connected to a base station in accordance with a legacy system support mode, it performs permutation for an uplink signal on a frequency axis in accordance with a first rule. If the user equipment is connected to the base station in accordance with a legacy system non-support mode, it performs permutation for the uplink signal on the frequency axis in accordance with a second rule. Cell ID corresponding to a secondary advanced preamble (SA-preamble) received from the base station is used for permutation based on the first rule and/or the second rule.
