1. A user equipment comprising:
a controller;
a transceiver that receives a configuration of a set of transmission configuration indicator (TCI) states associated with a serving cell for a physical downlink shared channel (PDSCH) transmission, each TCI state of the set of TCI states corresponds to one or more parameters for configuring a quasi-co-location (QCL) relationship between one or more downlink reference signals and one or more downlink reference signal ports associated with the PDSCH transmission;
wherein the transceiver further receives a physical downlink control channel (PDCCH) including a downlink control information (DCI) scheduling a PDSCH for the PDSCH transmission;
wherein the transceiver further receives a medium access control-control element (MAC-CE) indicating at least two configured TCI states of the set of TCI states;
wherein the controller selects the at least two configured TCI states of the set of TCI states indicated in the received MAC-CE based on a timing offset between a reception of the PDCCH and a reception of the PDSCH satisfying a threshold, and based on an absence of a TCI field in the DCI, the at least two configured TCI states comprising a first configured TCI state and a second configured TCI state different than the first configured TCI state, and wherein at least one configured TCI state of the at least two configured TCI states corresponds to a QCL-TypeD; and
wherein the controller further decodes the PDSCH based on the selected at least two configured TCI states of the set of TCI states.
