Abstract:
A method for transmitting an uplink signal by a user equipment (UE). The method includes receiving an uplink grant including a new data indicator (NDI) on a physical downlink control channel (PDCCH) from a network, determining whether the PDCCH is not addressed to a temporary cell identifier, determining whether the NDI has been toggled when the PDCCH is not addressed to the temporary cell identifier, and transmitting a new data to the network when the NDI has been toggled.
