Abstract
Provided are a method for a terminal transmitting an uplink control channel in a wireless communication system, and a device using same. The method comprises: determining the overlapping or not between a first physical uplink control channel (PUCCH) and a second PUCCH; and determining a transmission method for the first PUCCH and the second PUCCH on the basis of the determining. Here, the first PUCCH is an uplink control channel that is frequency division multiplexed (FDM) with a data channel, and the second PUCCH is an uplink control channel that is time division multiplexed (TDM) with the data channel.
Claims18
A method for transmitting uplink control information (UCI) and a sounding reference signal (SRS) by a user equipment (UE) in a wireless communication system, the method comprising:
- generating the UCI;
- transmitting more than one physical uplink shared channels (PUSCHs),
- wherein based on physical uplink control channel (PUCCH) resources of a first PUCCH not overlapping in time with the more than one PUSCHs, the UCI is transmitted through the first PUCCH, and
- wherein based on the PUCCH resources of the first PUCCH overlapping in time with the more than one PUSCHs, the UCI is transmitted through only a predefined Nth PUSCH among the more than one PUSCHs;
- determining that at least one SRS symbol, among a plurality of symbols to be used for transmitting the SRS, overlaps in time with at least one PUCCH symbol to be used for transmitting a second PUCCH;
- and
- based on the at least one SRS symbol overlapping in time with the at least one PUCCH symbol:
- based on the SRS being a periodic SRS, and based on the second PUCCH being configured to carry channel state information (CSI):
- (i) dropping, among the plurality of symbols to be used for transmitting the SRS, only the at least one SRS symbol that overlaps with the at least one PUCCH symbol, and (ii) transmitting the SRS through at least one symbol, among the plurality of symbols, excluding the at least one SRS symbol;
- and
- based on the SRS being an aperiodic SRS, and based on the second PUCCH being configured to carry periodic CSI:
- not transmitting the second PUCCH.

- a transceiver;
- at least one processor;
- and
- at least one computer memory operably connectable to the at least one processor and storing instructions that, when executed by the at least one processor, perform operations comprising:
- generating uplink control information (UCI);
- transmitting, by the transceiver, more than one physical uplink shared channels (PUSCHs),
- wherein based on physical uplink control channel (PUCCH) resources of a first PUCCH not overlapping in time with the more than one PUSCHs, the UCI is transmitted through the first PUCCH, and
- wherein based on the PUCCH resources of the first PUCCH overlapping in time with the more than one PUSCHs, the UCI is transmitted by the transceiver, through only a predefined Nth PUSCH among the more than one PUSCHs;
- determining that at least one sounding reference signal (SRS) symbol, among a plurality of symbols to be used for transmitting the SRS, overlaps in time with at least one PUCCH symbol to be used for transmitting a second PUCCH;
- and
- based on the at least one SRS symbol overlapping in time with the at least one PUCCH symbol:
- based on the SRS being a periodic SRS, and based on the second PUCCH being configured to carry channel state information (CSI):
- (i) dropping, among the plurality of symbols to be used for transmitting the SRS, only the at least one SRS symbol that overlaps with the at least one PUCCH symbol, and (ii) transmitting the SRS through at least one symbol, among the plurality of symbols, excluding the at least one SRS symbol;
- and
- based on the SRS being an aperiodic SRS, and based on the second PUCCH being configured to carry periodic CSI:
- not transmitting the second PUCCH.
