    Abstract: The present invention relates to a method and apparatus for efficiently controlling access for system load adjustment in mobile communication systems. A method for transmitting and receiving data by a terminal including a user equipment (UE) non access stratum (NAS) and a UE access stratum (AS) includes the steps of: receiving by the UE AE, information including emergency call-related information which includes barring information by type for the emergency call, from a base station; transmitting, by the UE NAS, a service request for the emergency call to the UE AS; and determining, by the UE AS, whether to bar the service request on the basis of emergency call-related information. During an emergency call transmission, network congestion can be easily controlled by enabling various types of emergency calls to be transmitted, and enabling access to be barred information according to the situation of a communication network and types of emergency calls.

    Abstract: A method and apparatus for transmitting a power headroom (PH) report by a terminal in a mobile communication system supporting carrier aggregation are provided. The method includes determining respective PHs for multiple activated serving cells based on a real transmission or a reference format, setting respective indicators for the PHs, wherein each indicator indicates that a corresponding PH is determined based on the real transmission or the reference format, and transmitting, to a base station, an extended PH report including the PHs and the indicators on one of the multiple activated serving cells. The each indicator is set to “0”, if the corresponding PH is determined based on the real transmission, and the each indicator is set to “1”, if the corresponding PH is determined based on the reference format.

    Abstract: A method and user equipment (UE) for obtaining power headroom information in a communication system are provided. The method includes acquiring information for a path loss reference, wherein the information for the path loss reference indicates whether the UE applies as the path loss reference either a downlink of a primary cell or a downlink of a secondary cell (SCell), triggering a power headroom report (PHR) if a path loss is changed more than a threshold for at least one activated cell which is used as the path loss reference, obtaining power headroom information for each activated cell, if extended PHR is used and an uplink resource is allocated for new transmission, and generating a medium access control (MAC) protocol data unit (PDU) including the power headroom information for each activated cell and an indicator for each activated cell. The indicator indicates whether power headroom information is based on a real physical uplink shared channel (PUSCH) transmission or a PUSCH reference format.
