An example method includes configuring a first sequence for a reference signal (RS) in response to determining that the RS includes information indicative of a first type of status information. The method also includes configuring a second sequence for the RS in response to determining that the RS includes information indicative of a second type of status information, where the RS is transmitted in response to determining an interference and based on the configured first sequence or second sequence. ## Claims ### Claim 1 A wireless communication method, comprising: configuring a first sequence for a reference signal (RS) in response to determining that the RS includes information indicative of a first type of status information, wherein the first type of status information indicates that enough interference mitigation operation is performed; configuring a second sequence for the RS in response to determining that the RS includes information indicative of a second type of status information, wherein the second type of status information indicates that not enough interference mitigation operation is performed; configuring for the RS the following repetition related information: a number of times the RS is repeatedly transmitted, wherein the number of times the RS is repeatedly transmitted is equal to a number of downlink-uplink (DL-UL) switching periods; and transmitting the RS based on the configured first sequence or second sequence and based on the repetition related information. ### Claim 2 (depends on 1) The method of claim 1, wherein the first type of status information indicates no further actions needed. ### Claim 3 (depends on 1) The method of claim 1, wherein the second type of status information indicates further actions needed. ### Claim 4 (depends on 1) The method of claim 1, wherein the first sequence or the second sequence are configured by a base station. ### Claim 5 (depends on 1) The method of claim 1, wherein the RS is a remote interference mitigation (RIM) RS. ### Claim 6 An apparatus for wireless communication comprising a processor, configured to implement a method, comprising: configure a first sequence for a reference signal (RS) in response to determining that the RS includes information indicative of a first type of status information, wherein the first type of status information indicates that enough interference mitigation operation is performed; configure a second sequence for the RS in response to determining that the RS includes information indicative of a second type of status information, wherein the second type of status information indicates that not enough interference mitigation operation is performed; configure for the RS the following repetition related information: a number of times the RS is repeatedly transmitted, wherein the number of times the RS is repeatedly transmitted is equal to a number of downlink-uplink (DL-UL) switching periods; and transmit the RS based on the configured first sequence or second sequence and based on the repetition related information. ### Claim 7 (depends on 6) The apparatus of claim 6, wherein the first type of status information indicates no further actions needed. ### Claim 8 (depends on 6) The apparatus of claim 6, wherein the second type of status information indicates further actions needed. ### Claim 9 (depends on 6) The apparatus of claim 6, wherein the first sequence or the second sequence are configured by a base station. ### Claim 10 (depends on 6) The apparatus of claim 6, wherein the RS is a remote interference mitigation (RIM) RS. ### Claim 11 A non-transitory computer readable program storage medium having code stored thereon, the code, when executed by a processor, causing the processor to implement a method, comprising: configuring a first sequence for a reference signal (RS) in response to determining that the RS includes information indicative of a first type of status information, wherein the first type of status information indicates that enough interference mitigation operation is performed; configuring a second sequence for the RS in response to determining that the RS includes information indicative of a second type of status information, wherein the second type of status information indicates that not enough interference mitigation operation is performed; configuring for the RS the following repetition related information: a number of times the RS is repeatedly transmitted, wherein the number of times the RS is repeatedly transmitted is equal to a number of downlink-uplink (DL-UL) switching periods; and transmitting the RS based on the configured first sequence or second sequence and based on the repetition related information. ### Claim 12 (depends on 11) The non-transitory computer readable program storage medium of claim 11, wherein the first type of status information indicates no further actions needed. ### Claim 13 (depends on 11) The non-transitory computer readable program storage medium of claim 11, wherein the second type of status information indicates further actions needed. ### Claim 14 (depends on 11) The non-transitory computer readable program storage medium of claim 11, wherein the first sequence or the second sequence are configured by a base station. ### Claim 15 (depends on 11) The non-transitory computer readable program storage medium of claim 11, wherein the RS is a remote interference mitigation (RIM) RS.
