Abstract
The present invention relates to a random access processing method, a processing method for processing different time-division setups, a method for reporting downlink timing differences, and a method for transmitting a sounding reference signal, when carrier aggregation technology is used in a wireless communication system. Through the present invention, a user can use improved carrier integration technology, and communicate without an erroneous operation.
Claims16
A Power Headroom Report (PHR) transmission method of a terminal in a wireless communication system using carrier aggregation technology, the method comprising:
- receiving a PHR trigger message from a primary cell in a random access procedure to at least one secondary cell;
- configuring PHR to the secondary cell with which the random access has completed;
- and
- transmitting the PHR to the primary cell.
A Power Headroom Report (PHR) reception method of a base station in a wireless communication system using a carrier aggregation technology, the method comprising:
- transmitting a PHR trigger message to a terminal in random access procedure with at least one secondary cell;
- and
- receiving a PHR configured for the secondary cell in which the random access has completed from the terminal.
A terminal transmitting Power Headroom Report (PHR) in a wireless communication system using a carrier aggregation technology, the terminal comprising:
- a transceiver which transmits and receives signal to and from a base station;
- and
- a controller which controls receiving a PHR trigger message from a primary cell in a random access procedure to at least one secondary cell, configuring PHR to the secondary cell with which the random access has completed, and transmitting the PHR to the primary cell.
A base station receiving Power Headroom Report (PHR) in a wireless communication system using a carrier aggregation technology, the base station comprising:
- a transceiver which transmits and receives signal to and from a terminal;
- and
- a controller which controls transmitting a PHR trigger message to a terminal in random access procedure with at least one secondary cell and receiving a PHR configured for the secondary cell in which the random access has completed from the terminal.
