Abstract
A method for a transmission and reception point (TRP) for controlling cross-link interference comprises the steps of: determining a timing advance (TA) value, for measuring or eliminating cross-link interference, in a set subframe if a section in which cross-link interferences occur between the TRP and one or more adjacent TRPs is configured; and transmitting the determined TA value in the set subframe to a terminal, wherein the section in which cross-link interference occurs can correspond to a section that is configured as an uplink section for the TRP, and as a downlink transmission section for the one or more adjacent TRPs.
Claims14
A method performed by a transmission and reception point (TRP) in a wireless communication system, the method comprising:
- receiving downlink/uplink configuration information to be used to measure a cross-link interference from at least one adjacent TRP;
- measuring the cross-link interference caused by a neighbor TRP based on the downlink/uplink configuration information;
- determining a value for controlling transmission timing of a downlink signal transmitted by the neighbor TRP based on the cross-link interference;
- and
- transmitting, to the neighbor TRP, a message through a X2 interface between the TRP and the neighbor TRP, the message including the value,
- wherein the downlink/uplink configuration information is received through the X2 interface.
A transmission and reception point (TRP) in a wireless communication system, the TRP comprising:
- a transceiver;
- and
- a processor coupled to the transceiver and configured to:
- receive downlink/uplink configuration information to be used to measure a cross-link interference from at least one adjacent TRP;
- measure the cross-link interference caused by a neighbor TRP based on the downlink/uplink configuration information;
- determine a value for controlling transmission timing of a downlink signal transmitted by the neighbor TRP based on the cross-link interference;
- and
- transmit, to the neighbor TRP, a message through a X2 interface between the TRP and the neighbor TRP, the message including the value,
- wherein the downlink/uplink configuration information is received through the X2 interface.
