    Abstract: Methods and apparatuses for downlink data buffering considering cross carrier scheduling in a wireless communication system are disclosed herein. In one method, the UE receives configuration of a first serving cell and a second serving cell from a network. The UE receives and/or monitors a first PDCCH transmitted on a scheduling CORESET of the second serving cell, wherein the first PDCCH schedules a first PDSCH transmitted on the first serving cell. The UE receives and/or monitors a second PDCCH transmitted on a scheduling CORESET of the second serving cell, wherein the second PDCCH schedules a second PDSCH transmitted on the second serving cell. The UE receives and/or buffers the second PDSCH via a TCI state used for PDCCH quasi co-location indication of the CORESET with the lowest CORESET-ID in the latest slot in which one or more CORESETs are configured for the UE, before the UE decodes successfully the second PDCCH. The UE does not receive and/or buffer the first PDSCH before the UE decodes successfully the first PDCCH.

    Abstract: A method and apparatus are disclosed from the perspective of a UE (User Equipment) and/or a base station. In one embodiment, the method includes the base station configuring the UE with a first serving cell and a second serving cell. The method also includes the base station configuring the UE with a periodicity for monitoring a downlink control signal in the first serving cell, wherein the base station is not allowed to configure the UE such that the periodicity includes a non-integer number of symbol(s) of the second serving cell, and wherein the downlink control signal includes a pre-emption indication (PI) for the second serving cell.
