SYSTEMS AND METHODS FOR MULTI-CONNECTIVITY OPERATION

摘要

A method for sending a power headroom report (PHR) by a User Equipment (UE) is described. The method includes obtaining a value of a power headroom for each activated serving cell with configured uplink corresponding to a second set of cell(s). The method also includes generating an extended power headroom MAC control element based on the obtained values and information related to power management corresponding to a first set of cell(s). The method further includes transmitting the extended power headroom MAC control element.
