Title:
SENDING METHOD, RECEIVING METHOD, SENDING DEVICE AND RECEIVING DEVICE FOR SIGNALS IN MULTI-CARRIER SYSTEM
Document Type and Number:
WIPO Patent Application WO/2009/155859
Kind Code:
A1
Abstract:
A sending method, a receiving method, a sending device and a receiving device for signals in a multi-carrier system are provided. The sending method includes the following steps. Sequences are generated according to the cell identities used as parameters. The cell identities satisfy the predefined function correspondences between the cell identities of the multiple carriers in the same cell. Said correspondences include the correspondences between the results obtained from rounding down to integers the quotients obtained from dividing the cell identities of the carriers by N, wherein N is any integer which is more than or equal to 0 and less than or equal to the maximum value of the cell identity. The signals formed by the sequences or formed due to the action of the sequences are sent. The methods and devices make cell planning for the multi-carrier system easy and avoid the uplink pilot interference between different cells.
