Abstract
PROBLEM TO BE SOLVED: To disclose a method and a device for transmitting a pilot by a plurality of antennas.
SOLUTION: A wireless transmission/reception unit (WTRU) can transmit a main DPCCH (dedicated physical control channel) and at least one sub-DPCCH via a plurality of antennas by use of different channelization codes. The first 8 pilot symbols of the sub-DPCCH may be the same as the pilot symbols with length 8 of the main DPCCH. The sub-DPCCH can include the same number of pilot bits as the main DPCCH in each of a normal mode and a compression mode. Transmission power of the sub-DPCCH is adjustable on the basis of a ratio of the numbers of the pilot symbols in the main DPCCH and the sub-DPCCH. When required transmission power exceeds the maximum allowable transmission power of the WTRU power scaling can be equally applied to a main DPCCJ and a sub-DPCCJ.
