摘要：
The present invention relates to methods, apparatuses and a computer program product for random access channel enhancement for carrier aggregation with different uplink/downlink configuration. The present invention includes detecting, at a user equipment, a downlink control channel in a specific downlink subframe on a first component carrier, receiving, at the user equipment, a downlink shared channel on the first component carrier, and transmitting, after a predetermined period, a random access channel in a specific uplink subframe on a second component carrier, the specific uplink subframe overlapping the specific downlink subframe on the first component carrier.
