Method and apparatus for transmitting and receiving a signal on PUSCH in a wireless communication
A method and apparatus for transmitting signals on a PUSCH in a wireless communication system are provided. Specifically, a method performed by a terminal includes receiving resource information for transmitting uplink data and channel state information (CSI) on a PUSCH from a base station; receiving first downlink control information (DCI) including control information on slot timing related to the uplink data transmission from the base station; comparing a first time related to computation of the uplink data and CSI and a second time related to computation of only the CSI; and transmitting, if a value of the slot timing is greater than the second time and smaller than the first time, only the CSI on the PUSCH to the base station.
1. A method of transmitting, by a terminal, a signal on a Physical Uplink Shared Channel (PUSCH) in a wireless communication system, the method comprising:
receiving, from the base station, first downlink control information (DCI) comprising first control information for a slot timing related to the PUSCH and second control information for triggering transmission of uplink data and channel state information (CSI) together on the PUSCH;
obtaining a first time and a second time, wherein the first time is a time required for the terminal to transmit together the uplink data and the CSI after receiving the first DCI, and the second time is a time required for the terminal to transmit only the CSI after receiving the first DCI; and
transmitting, to the base station, only the CSI on the PUSCH based on a value of the slot timing being greater than the second time and less than the first time,
wherein a range of the slot timing related to the PUSCH is determined based on a use for the PUSCH;
wherein a minimum value of the slot timing is determined to be the larger value among a minimum value of an offset required for uplink data transmission (Z) configured by the base station and a minimum value of aperiodic CSI reporting offset (Y) configured by the base station, and
wherein a maximum value of the slot timing is determined to be the smaller value among a maximum value of the offset required for uplink data transmission (Z) and a maximum value of the aperiodic CSI reporting offset (Y).
2. The method of claim 1 , wherein the PUSCH comprises a bit sequence for the CSI and a predefined bit sequence.
3. The method of claim 2 , wherein all bits of the predefined bit sequence have a value of 0.
4. The method of claim 1 , wherein a value of the second time is received from the base station through second DCI.
5. The method of claim 1 , wherein both the uplink data and the CSI are dropped based on the timing offset being less than the first time.
6. A terminal for transmitting a signal on a Physical Uplink Shared Channel (PUSCH) in a wireless communication system, the terminal comprising:
a transmitter for transmitting a wireless signal;
a receiver for receiving a wireless signal; and
a processor functionally connected to the transmitter and the receiver, wherein the processor is configured to:
control the receiver to receive, from the base station, first downlink control information (DCI) comprising first control information for a slot timing related to the PUSCH and second control information for triggering transmission of uplink data and channel state information (CSI) together on the PUSCH;
obtain a first time and a second time, wherein the first time is a time required for the terminal to transmit together the uplink data and the CSI after receiving the first DCI, and the second time is a time required for the terminal to transmit only the CSI after receiving the first DCI; and
control the transmitter to transmit, to the base station, only the CSI on the PUSCH based on a value of the slot timing being greater than the second time and less than the first time,
wherein a range of the slot timing related to the PUSCH is determined based on a use for the PUSCH;
wherein a minimum value of the slot timing is determined to be the larger value among a minimum value of an offset required for uplink data transmission (Z) configured by the base station and a minimum value of aperiodic CSI reporting offset (Y) configured by the base station, and
wherein a maximum value of the slot timing is determined to be the smaller value among a maximum value of the offset required for uplink data transmission (Z) and a maximum value of the aperiodic CSI reporting offset (Y).
7. The terminal of claim 6 , wherein the PUSCH comprises a bit sequence for the CSI and a predefined bit sequence.
8. The terminal of claim 7 , wherein all bits of the predefined bit sequence have a value of 0.
9. The terminal of claim 6 , wherein the processor is further configured to control the receiver to receive a value of the second time from the base station through second DCI.
10. The terminal of claim 6 , wherein both the uplink data and the CSI are dropped based on the timing offset being less than the first time.
