Abstract: A method and apparatus are disclosed from the perspective of a UE. In one embodiment, the method includes the UE receiving a first configuration for PUSCH transmission with configured grant, wherein the first configuration indicates a first SRI value, and the first SRI value is associated with a first reference signal. The method also includes the UE transmitting a first PUSCH with configured grant by using a transmission precoder or a spatial filter, wherein the transmission precoder or the spatial filter is for transmitting the first reference signal. The method further includes the UE transmitting, in response to detecting beam failure recovery, a RA preamble on a PRACH resource for beam failure recovery, wherein the PRACH resource is associated with a candidate reference signal. In addition, the method includes the UE monitoring and/or receiving a response corresponding to the RA preamble via one or more antenna port quasi co-location parameters associated with the candidate reference signal during the BFR procedure. Furthermore, the method includes the UE transmitting, if the UE receives the response, a second PUSCH with configured grant on occasions configured in the first configuration via using the same transmission precoder or spatial filter for transmitting the PRACH resource until the UE receives a second configuration comprising SRI for PUSCH transmission with configured grant.

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.
