Abstract
A method of handling a communication operation for a communication device comprising performing a reception in a first subframe of a time-division duplexing (TDD) carrier from a network; and performing a transmission for responding the reception via a second subframe of a uplink (UL) carrier to the network; wherein the UL carrier is a frequency-division duplexing (FDD) UL carrier, or is another TDD carrier with an UL/downlink (DL) configuration where all subframes are UL subframes.
Claims27
A communication device for handling a communication operation, comprising:
- a storage device;
- and
- a processing circuit, coupled to the storage device, wherein the storage device stores instructions, and the processing circuit is configured to execute the instructions of:
- performing a reception in a first subframe of a time-division duplexing (TDD) carrier from a network;
- and
- performing a transmission for responding to the reception via a second subframe of a uplink (UL) carrier to the network;
- wherein the UL carrier is a frequency-division duplexing (FDD) UL carrier, or is another TDD carrier with an UL/downlink (DL) configuration where all subframes are UL subframes;
- wherein the reception comprises at least one packet, and the transmission comprises a hybrid automatic repeat request (HARQ) feedback for responding to the at least one packet in the reception;
- wherein a HARQ process number of the HARQ feedback is not greater than a maximum number of HARQ processes, MDL_HARQ, determined according to the reception and the transmission;
- wherein MDL_HARQ for a UL/DL configuration 4 is 8, or MDL_HARQ for a UL/DL configuration 5 is 8.
A communication device for handling a communication operation, comprising:
- a storage device;
- and
- a processing circuit, coupled to the storage device, wherein the storage device stores instructions, and the processing circuit is configured to execute the instructions of:
- performing a transmission in a first subframe of a uplink (UL) carrier to a network;
- and
- performing a reception for responding to the transmission via a second subframe of a time-division duplexing (TDD) carrier from the network;
- wherein the UL carrier is a frequency-division duplexing (FDD) UL carrier, or is another TDD carrier with an UL/downlink (DL) configuration where all subframes are UL subframes;
- wherein the second subframe is a number of subframes after the first subframe and the number of subframes is a constant regardless of a subframe index of the first subframe;
- wherein the reception is performed via a physical HARQ indicator channel (PHICH) of the second subframe of the TDD carrier.
A communication device for handling a communication operation, comprising:
- a storage device;
- and
- a processing circuit, coupled to the storage device, wherein the storage device stores instructions, and the processing circuit is configured to execute the instructions of:
- performing a reception in a first subframe of a downlink (DL) carrier from a network;
- and
- performing a transmission for responding to the reception via a second subframe of a time-division duplexing (TDD) carrier to the network;
- wherein the DL carrier is a frequency-division duplexing (FDD) DL carrier, or is another TDD carrier with an uplink (UL)/DL configuration where all subframes are DL subframes;
- wherein the reception comprises at least one packet, and the transmission comprises a hybrid automatic repeat request (HARQ) feedback for responding to the at least one packet in the reception;
- wherein a HARQ process number of the HARQ feedback is not greater than a maximum number of HARQ processes, MDL_HARQ, determined according to the reception and the transmission;
- wherein MDL_HARQ for a UL/DL configuration 0 is 10, MDL _HARQ for a UL/DL configuration 1 is 11, MDL_HARQ for a UL/DL configuration 2 is 12, MDL_HARQ for a UL/DL configuration 3 is 15, or MDL_HARQ for a UL/DL configuration 4 is 16.
