Abstract: 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.

Abstract: A first method is disclosed, the method comprising: receiving, by a first apparatus, one or more values for one or more transmission parameters from a second apparatus, wherein the one or more transmission parameters relate to one or more transmissions from the second apparatus to the first apparatus; determining a target quality based at least on the one or more values for the one or more transmission parameters; determining feedback information based at least on the determined target quality; and transmitting the feedback information to the second apparatus. Corresponding methods for the second apparatus, a system, and computer programs are disclosed.

Abstract: Certain examples of the present disclosure relate to an apparatus (10), method (400) and computer program (14) for: receiving at least one first signal (501) comprising an indication of at least one bit of a first System Frame Number, SFN (302); determining, based at least in part on the received at least one first signal, at least one value of a reliability metric for the at least one bit of the first SFN; receiving at least one second signal (503) comprising an indication of at least one bit of a second SFN different than the first SFN; determining, based at least in part on the received at least one second signal and the determined at least one value of the reliability metric for the at least one bit of the first SFN, at least one value of a reliability metric for the at least one bit of the second SFN.

Abstract: 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.

Abstract: There is provided a network element comprising means for defining one or more channel state information reporting configurations; means for determining, among the one or more channel state information reporting configurations, configurations for which a partial information update is allowable; and means for providing indication of the determined configurations to a user equipment. There is also provided a user equipment comprising means for determining which channel state information reporting configuration is applicable for a partial information update; means for examining whether a current channel state information reporting configuration is applicable for a partial information update; and means for, based on the examining, transmitting either a channel state information report containing providing a partial information update, when applicable, or transmitting a complete channel state information report, when not applicable.
