Abstract
To perform a random access procedure on licensed and unlicensed carriers, a user equipment may receive a system information block (SIB) on a downlink carrier in a first carrier frequency, where the SIB includes configuration information for a first uplink carrier and a second uplink carrier, and transmit a physical random access channel (PRACH) either on the first uplink carrier or on the second uplink carrier. A response to the transmitted PRACH received by the user equipment on a downlink carrier may schedule transmission of data channel. The SIB preferably includes configuration information for determining a power for the PRACH transmission on the first and second uplink carriers. The frequency band of the downlink carrier is same as the frequency band of the first uplink carrier and is different than that of the second uplink carrier, which has a frequency lower than the frequency of the first UL carrier.
