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.
Claims4
A method for transmitting an uplink signal by a user equipment (UE), the method comprising:
- receiving an uplink grant including a new data indicator (NDI) through 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 through a physical uplink shared channel (PUSCH) to the network when the NDI has been toggled.
A user equipment (UE) comprising:
- a receiver configured to receive an uplink grant including a new data indicator (NDI) through a physical downlink control channel (PDCCH) from a network;
- a processor configured to determine whether the PDCCH is not addressed to a temporary cell identifier, and to determine whether the NDI has been toggled when the PDCCH is not addressed to the temporary cell identifier;
- and
- a transmitter configured to transmit a new data through a physical uplink shared channel (PUSCH) to the network when the NDI has been toggled.
