1. A communication method performed by a user equipment (UE), the method comprising:

  • receiving, at the UE, cyclic shift information for reference signal;

    determining, at the UE, a dynamic cyclic shift value based on the cyclic shift information for reference signal;

    generating, at the UE, a reference signal by cyclically shifting a sequence at least based on the dynamic cyclic shift value;

    transmitting, at the UE, data and the reference signal using one or more uplink radio resources; and

    receiving, at the UE, Acknowledgement/Negative Acknowledgement (ACK/NACK) for the transmitted data using a Physical Hybrid ARQ Indicator Channel (PHICH) resource,wherein the dynamic cyclic shift value is determined based on the cyclic shift information for reference signal according to Table 1 and the PHICH resource is determined at least based on the cyclic shift information for reference signal
