A primary cell and at least one secondary cell are configured with the UE. One logical channel identifier (LCID) field is configured in a medium access control (MAC) sub-header. The one LCID field indicates a presence of a PH MAC control element (CE). A MAC protocol data unit (PDU) comprising the MAC sub-header and the PH MAC CE is transmitted. The PH MAC CE includes PH information for both the primary cell and the at least one secondary cell."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method for allowing terminal to transmit power headroom information in wireless communication system and device therefor","description":"A method and a user equipment (UE) are described for transmitting power headroom (PH) information in a wireless communication system.
