1. A user equipment, comprising:
one or more memories; and
one or more processors coupled to the one or more memories, wherein the one or more processors are configured to:
receive at least one medium access control-control element (MAC-CE) comprising spatial relation information;
determine whether a single component carrier indicated by the MAC-CE is a member of a plurality of component carriers, or determine whether the user equipment received information identifying the plurality of component carriers;
selectively apply the spatial relation information to the single component carrier indicated by the MAC-CE or to the plurality of component carriers depending on a result of the determination of whether the single component carrier indicated by the MAC-CE is the member of the plurality of component carriers, or depending on a result of the determination of whether the user equipment received the information identifying the plurality of component carriers; and
transmit an uplink transmission via the plurality of component carriers or the single component carrier according to the selectively applying the spatial relation information,
wherein the one or more processors are further configured to:
based on a determination that the single component carrier indicated by the MAC-CE is the member of the plurality of component carriers, apply the spatial relation information to the plurality of component carriers or apply the spatial relation information to all bandwidth parts (BWPs) of the plurality of component carriers; or
based on a determination that the single component carrier indicated by the MAC-CE is not the member of the plurality of component carriers, apply the spatial relation information to the single component carrier or apply the spatial relation information to all bandwidth parts (BWPs) of the single component carrier; or
based on a determination that the user equipment did not receive the information identifying the plurality of component carriers, apply the spatial relation information to the single component carrier or apply the spatial relation information to all bandwidth parts (BWPs) of the single component carrier.
