Method and apparatus for reporting channel state information in wireless communication systems

A method performed by a base station of receiving channel state information, the method comprising:

• transmitting, to a first user equipment (UE), channel measurement resource (CMR) configuration information;
• and
• receiving, from the first UE, information about one or more signal to interference pulse noise ratio (SINR) related to a downlink,
• wherein the one or more SINR related to the downlink are measured at the first UE based on at least one downlink reference signal (DL RS) received on a CMR identified from the CMR configuration information and at least one uplink reference signal (UL RS) received on an uplink interference measurement resource (UL IMR) identified from UL IMR configuration information, and
• the UL IMR configuration information including at least one sounding reference signal (SRS) resource information is received at the first UE from the base station for measurement of cross link interference (CLI) between at least one second UE and the first UE.

A first user equipment (UE) configured to report channel state information, the first UE comprising:

• a transceiver;
• and
• at least one processor coupled with the transceiver, wherein the at least one processor is configured to:
• receive, from a base station, channel measurement resource (CMR) configuration information,
• receive, from the base station, uplink interference measurement resource (UL IMR) configuration information including at least one sounding reference signal (SRS) resource information for measurement of cross link interference (CLI) between at least one second UE and the first UE,
• measure one or more signal to interference pulse noise ratio (SINR) related to a downlink based on at least one downlink reference signal (DL RS) received on a CMR identified from the CMR configuration information and at least one uplink reference signal (UL RS) received on a UL IMR identified from the UL IMR configuration information;
• and
• transmit, to the base station, information about the measured one or more SINR related to the downlink.
