METHOD AND DEVICE FOR CHANNEL QUALITY DETECTION

摘要

A method and device for channel quality detection. A channel quality detection pilot is allocated at the symmetrical position of both ends of system frequency band in the uplink pilot time slot, the summation of the frequency band occupied by the channel quality detection pilot allocated in the uplink pilot time slot and the frequency band occupied by the channel quality detection channel allocated in the uplink sub-frames covers the frequency band width of whole system; and a random access channel is allocated in the rest frequency band of the uplink pilot time slot. The method and device can guarantee that channel quality detection of whole system may be implemented when a random access channel is allocated in the uplink pilot time slot.
