摘要: 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 prohibitPHR-Timer expires and a path loss is changed more than a threshold for at least one activated cell which is used as the path loss reference, and obtaining power headroom information for each activated cell, if extended PHR is used and an uplink resource is allocated for new transmission.

摘要: A method for reporting performance of a terminal in a mobile communication system includes the steps of receiving a request for performance reporting from a base station, determining an indicator of whether a delay time related operation that the terminal supports is in correspondence with the request which corresponds to a pre-set condition, and transmitting a message including the determined indicator to the base station. The size of the performance reporting message may be minimized in reporting the performance of the terminal.

摘要: The present invention relates to a method and apparatus for efficiently controlling access for system load adjustment in mobile communication systems. In a wireless communication system according to one embodiment, the 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. According to one embodiment, during the 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. Also, even when a specific type of emergency call is barred from access, the terminal can change to another type of emergency call and try for access. Therefore, it is effective in that an emergency call can be transmitted in various schemes even in a state where the network is congested.
