Systems, methods, apparatuses, and computer program products for improved handling of cross-link interference on physical random access channel occasions on flexible or full duplexing slots are provided. For example, a method can include providing a plurality of random access channel configurations to a user equipment. A first random access channel configuration of the plurality of random access channel configurations can be for a first set of symbols or slots and a second random access channel configuration of the plurality of random access channel configurations can be for a second set of symbols or slots. The method can also include providing, to the user equipment, one or more parameters configured to steer the user equipment to select between the first set of symbols or slots or the second set of symbols or slots to be used when performing a random access transmission. The method can further include receiving a random access transmission on the selected set of symbols or slots based on one of the plurality of random access channel configurations.

Techniques are provided for facilitating channel estimation to mitigate cross-link interference between a base station in a first cell and at least one neighbor base station. In the context of a method performed by the base station, an indication for assistance information to support channel estimation is provided from the base station to at least one neighbor base station. The method also includes receiving assistance information from at least one neighbor base station. The method further includes causing a time-frequency muting pattern to be signaled to at least one user equipment in a first cell. The method also includes estimating an interference covariance matrix from an interfering link of the at least one neighbor base station based at least in part on the assistance information and estimating the desired signal based on the interference covariance matrix. Corresponding method, apparatus and computer-readable storage mediums are also provided for a base station.
