1. A method for a user equipment (UE), comprising:
receiving multiple signals causing a Quasi co-location TypeD (QCL-TypeD) collision, wherein the multiple signals are configured in one of two transmission schemes, wherein the two transmission schemes comprise a first transmission scheme type where the signals are transmitted in a single frequency network (SFN) manner and a second transmission scheme type where the signals are transmitted in a non-SFN manner within a band or band group and overlapped in time domain, and where two Transmission Configuration Indicator (TCI) States are applicable for PDCCH;
determining which of the multiple signals to receive based on whether a type of transmission scheme associated with each of the multiple signals uses the SFN manner or the non-SFN manner and one of a signal reception priority rule, a scheduling restriction, or a QCL-TypeD selection priority rule;
selecting one or more highest priority Search Spaces (SSs) based on the signal reception priority rule or the QCL-TypeD selection priority rule, wherein when two SSs are selected with the two TCI states, other normal PDCCH Quasi co-located with one of the two TCI States are also selected; and
processing a received signal from the one or more highest priority SSs and the other normal PDCCH Quasi co-located with one of the two TCI States based on which of the multiple signal are determined to be received based on the type of transmission scheme associated with each of the multiple signals and one of the signal reception priority rule, the scheduling restriction, or the QCL-TypeD selection priority rule.
