Abstract
Methods and apparatuses for determining default beam(s) are disclosed. A method comprises receiving an activation command for the activated BWP of a serving cell, wherein the activation command contains codepoints pointing to TCI state(s), and at least one codepoint points to two TCI states; and determining default TCI state(s) for reception of downlink signal according to the TCI state(s) used for receiving the PDCCH or at least one TCI state pointed to by a codepoint pointing to two TCI states, when a scheduling offset between a reception of the PDCCH carrying DCI and the corresponding downlink signal scheduled or triggered by the DCI is less than a predetermined threshold.
