Method for transmitting uplink signal and apparatus therefor
The present invention relates to a wireless communication system. Particularly, the present invention relates to a method and an apparatus therefor, the method comprising the steps of: transmitting a PUSCH on a first RB set of subframe #n; transmitting a PUCCH on a second RB set of subframe #n; and when the first RB set and the second RB set overlap, restricting transmission of the PUCCH on one or more RBs where the first RB set and the second RB set overlap.
1. A method of performing uplink transmission a user equipment (UE) in a wireless communication system, the method comprising:
performing a procedure for transmitting a Physical uplink shared channel (PUSCH) on a first resource block (RB) set of a subframe #n;
performing a procedure for transmitting a physical uplink control channel (PUCCH) on a second RB set of the subframe #n; and
when the first RB set overlaps the second RB set, setting a limit on transmission of the PUCCH in one or more RBs at which the first RB set and the second RB set overlap,
wherein transmission of the PUCCH is restricted only in one or more RBs at which the first RB set and the second RB set overlap,
wherein the PUCCH is partly transmitted in the remaining RB(s) of the second RB set,
wherein uplink control information (UCI) is transmitted via the PUCCH, and
wherein partial transmission of the PUCCH reduces a payload size of the UCI scheduled to be transmitted in the subframe #n in proportion to the number of one or more RBs at which the first RB set and the second RB set are overlapped.
2. The method of claim 1 , wherein transmission of the PUSCH is normally performed in one or more RBs at which the first RB set and the second RB set overlap.
3. The method of claim 1 , wherein transmission of the PUCCH is restricted in all RBs of the second RB set.
4. The method of claim 3 , wherein when transmission of periodic channel state information (p-CSI) is scheduled in the subframe #n, the transmission of the p-CSI is dropped and wherein when transmission of hybrid ARQ acknowledgement (HARQ-ACK) is scheduled in the subframe #n, the HARQ-ACK is transmitted via the PUSCH.
5. A user equipment (UE) used in a wireless communication system, comprising:
a transmitter and a receiver; and
at least one processor,
wherein the at least one processor is configured to:
perform a procedure for transmitting a Physical uplink shared channel (PUSCH) on a first resource block (RB) set of a subframe #n,
perform a procedure for transmitting a physical uplink control channel (PUCCH) on a second RB set of the subframe #n,
when the first RB set overlaps the second RB set, set a limit on transmission of the PUCCH in one or more RBs at which the first RB set and the second RB set overlap,
wherein transmission of the PUCCH is restricted only in one or more RBs at which the first RB set and the second RB set overlap,
wherein the PUCCH is partly transmitted in the remaining RB(s) of the second RB set, and
wherein uplink control information (UCI) is transmitted via the PUCCH, and
wherein partial transmission of the PUCCH reduces a payload size of the UCI scheduled to be transmitted in the subframe #n in proportion to the number of one or more RBs at which the first RB set and the second RB set are overlapped.
6. The UE of claim 5 , wherein transmission of the PUSCH is normally performed in one or more RBs at which the first RB set and the second RB set overlap.
7. The UE of claim 5 , wherein transmission of the PUCCH is restricted in all RBs of the second RB set.
8. The UE of claim 7 , wherein when transmission of periodic channel state information (p-CSI) is scheduled in the subframe #n, the transmission of the p-CSI is dropped and wherein when transmission of hybrid ARQ acknowledgement (HARQ-ACK) is scheduled in the subframe #n, the HARQ-ACK is transmitted via the PUSCH.
