Method of performing channel sounding in frequency duplex system |
摘要 |
A method of performing channel sounding in a frequency division duplex (FDD) system in which an uplink frame and a downlink frame use different frequency bands includes dividing a transmission bandwidth with respect to the uplink frame into a plurality of sounding zones, allocating at least one of the plurality of sounding zones to a user equipment and receiving a sounding signal from the user equipment through the allocated sounding zone. Inter-cell interference can be mitigated and overhead due to transmission of the sounding signal can be reduced. |
