Abstract

Claims (38)

1 . An operating method of a first terminal in a wireless communication system, the operating method comprising:

receiving, from a base station, at least one configuration information associated with a reference signal for measuring cross-link interference (CLI);

selecting a measurement band based on the at least one configuration information in case that an uplink bandwidth part of a second terminal and an active downlink bandwidth part of the first terminal are different from each other;

measuring CLI through the reference signal based on the measurement band excluding a portion outside the active downlink bandwidth part of the first terminal; and

reporting a result of the measuring, to the base station.

2 . The operating method of claim 1 , further comprising determining a bandwidth for measuring the CLI among the active downlink bandwidth part,

wherein the CLI is determined based on a reference signal measured at the determined bandwidth.

3 . The operating method of claim 2 , wherein the determined bandwidth corresponds to, from among the uplink bandwidth, at least one of a narrowest bandwidth, a part configured as an initial uplink bandwidth, a part configured as a default uplink bandwidth part, or a part configured by the base station.

4 . The method of claim 1 , wherein the reporting of the result of the measuring comprises dividing the active downlink bandwidth part into subbands and reporting the result of the measuring, based on the subbands, and

wherein the CLI is determined based on a reference signal measured in a subband in which the uplink bandwidth and the active downlink bandwidth part match each other, from among the reference signal.

5 . The method of claim 1 , further comprising receiving, from the base station, an indication about whether to stop measurement of the CLI through higher layer signaling,

wherein the CLI is determined according to a reference signal measured based on the indication.

6 . The method of claim 1 , wherein the CLI is measured according to a configuration according to layer 1 signaling or layer 3 signaling.

7 . A first terminal in a wireless communication system, the first terminal comprising:

a transceiver; and

at least one processor connected to the transceiver,

wherein the at least one processor is configured to:

receive, from a base station, at least one configuration information associated with a reference signal for measuring cross-link interference (CLI),

select a measurement band based on of the at least one configuration information in case that an uplink bandwidth part of a second terminal and an active downlink bandwidth part of the first terminal are different from each other,

measure CLI through the reference signal based on the measurement band excluding a portion outside the active downlink bandwidth part of the first terminal, and

report a result of the measuring, to the base station.

8 . The first terminal of claim 7 , wherein the at least one processor is further configured to determine a bandwidth for measuring the CLI from among the active downlink bandwidth part, and

wherein the CLI is determined based on a reference signal measured at the determined bandwidth.

9 . The first terminal of claim 8 , wherein the determined bandwidth corresponds to, from among the uplink bandwidth, at least one of a narrowest bandwidth, a part configured as an initial uplink bandwidth, a part configured as a default uplink bandwidth part, or a part configured by the base station.

10 . The first terminal of claim 7 , wherein the at least one processor is further configured to divide the active downlink bandwidth part into subbands and report the result of the measuring, based on the subbands, and

the CLI is determined based on a reference signal measured in a subband in which the uplink bandwidth and the active downlink bandwidth part match each other, from among the reference signal.

11 . The first terminal of claim 7 , wherein the at least one processor receives, from the base station, an indication about whether to stop measurement of the cross-link interference, through higher layer signaling, and the CLI is determined according to a reference signal measured based on the indication.

12 . The first terminal of claim 7 , wherein the CLI is measured according to a configuration according to layer 1 signaling or layer 3 signaling.

13 . An operating method of a base station in a wireless communication system, the operating method comprising:

transmitting, to a first terminal, at least one configuration information associated with a reference signal for measuring cross-link interference (CLI), wherein CLI measured through the reference signal is measured based on the at least one configuration information selected by the first terminal when an uplink bandwidth part of a second terminal and an active downlink bandwidth part of the first terminal are different from each other, and wherein a CLI measurement band excludes a portion outside the active downlink bandwidth part of the first terminal, and

receiving a result of measuring, from the first terminal.

14 . A base station in a wireless communication system, the base station comprising:

a transceiver; and

at least one processor connected to the transceiver,

wherein the at least one processor is further configured to:

transmit, to a first terminal, at least one configuration information associated with a reference signal transmitted by a second terminal, wherein cross-link interference (CLI) measured through the reference signal is measured based on the at least one configuration information selected by the first terminal when an uplink bandwidth part of a second terminal and an active downlink bandwidth part of the first terminal are different from each other, and wherein a CLI measurement band excludes a portion outside the active downlink bandwidth part of the first terminal, and

receive a result of the measuring, from the first terminal.

15 . The base station of claim 14 , wherein the CLI is measured according to a configuration according to layer 1 signaling or layer 3 signaling.
