Method and apparatus for transmitting and receiving uplink reference signal in wireless communication system
A terminal and a method performed by the terminal are provided for use in a wireless communication system. The method includes receiving configuration information associated with a sounding reference signal (SRS) by higher layer signaling; receiving downlink control information (DCI) for triggering the SRS; and transmitting, based on the configuration information and the DCI, the SRS in an available slot counting from a reference slot.
1 . A method performed by a terminal in a wireless communication system, the method comprising:
receiving configuration information associated with a sounding reference signal (SRS) through higher layer signaling;
receiving, in a slot n, downlink control information (DCI) for triggering the SRS; and
transmitting, based on the configuration information and the DCI, the SRS in a slot,
wherein the configuration information includes a slot offset (X) and at least one candidate value from a reference slot n+X to the slot in which the SRS is transmitted.
2 . The method of claim 1 , wherein the slot in which the SRS is transmitted is determined based on the at least one candidate value, as a u-th available slot.
3 . The method of claim 1 , wherein the DCI includes an offset indicator to indicate one of the at least one candidate value.
4 . The method of claim 3 , wherein a bit number of the offset indicator is determined based on a number of the at least one candidate value.
5 . A terminal in a wireless communication system, the terminal comprising:
a transceiver; and
at least one processor coupled with the transceiver and configured to:
receive configuration information associated with a sounding reference signal (SRS) through higher layer signaling,
receive, in a slot n, downlink control information (DCI) for triggering the SRS, and
transmit, based on the configuration information and the DCI, the SRS in a slot,
wherein the configuration information includes a slot offset (X) and at least one candidate value from a reference slot n+X to the slot in which the SRS is transmitted.
6 . The terminal of claim 5 , wherein the slot in which the SRS is transmitted is determined based on the at least one candidate value, as a u-th available slot.
7 . The terminal of claim 5 , wherein the DCI includes an offset indicator to indicate one of the at least one candidate value.
8 . The method of claim 7 , wherein a bit number of the offset indicator is determined based on a number of the at least one candidate value.
9 . A method performed by a base station (BS) in a wireless communication system, the method comprising:
transmitting, to a terminal, configuration information associated with a sounding reference signal (SRS) through higher layer signaling;
transmitting, in a slot n, downlink control information (DCI) for triggering the SRS; and
receiving, based on the configuration information and the DCI, the SRS in a slot,
wherein the configuration information includes a slot offset (X) and at least one candidate value from a reference slot n+X to the slot in which the SRS is received.
10 . The method of claim 9 , wherein the slot in which the SRS is received is determined based on the at least one candidate value, as a u-th available slot.
11 . The method of claim 9 , wherein the DCI includes an offset indicator to indicate one of the at least one candidate value.
12 . The method of claim 11 , wherein a bit number of the offset indicator is determined based on a number of the at least one candidate value.
13 . A base station (BS), in a wireless communication system, the BS comprising:
a transceiver; and
at least one processor coupled with the transceiver and configured to:
transmit, to a terminal, configuration information associated with a sounding reference signal (SRS) through higher layer signaling,
transmit, in a slot, downlink control information (DCI) for triggering the SRS, and
receive, based on the configuration information and the DCI, the SRS in a slot,
wherein the configuration information includes a slot offset (X) and at least one candidate value from a reference slot n+X to the slot in which the SRS is received.
14 . The BS of claim 13 , wherein the slot in which the SRS is received is determined based on the at least one candidate value, as a u-th available slot.
15 . The BS of claim 13 , wherein the DCI includes an offset indicator to indicate one of the at least one candidate value.
16 . The BS of claim 15 , wherein a bit number of the offset indicator is determined based on a number of the at least one candidate value.
