摘要:
An Orthogonal Frequency Division Multiplexing (OFDM) symbol for transmission from a non-reference transceiver to a user equipment (UE) in a mobile communication system is generated by ascertaining a general timing for transmission of OFDM symbols, in which the general timing is associated with a reference transceiver. A UE timing relative to the general timing is ascertained. An initial resource element (RE) value is adjusted by a pre-compensating amount to obtain a pre-compensated RE value, in which the pre-compensating amount is based on the UE timing relative to the general timing. The pre-compensated resource element value is supplied as one of a plurality of values to be transmitted. An IFFT is performed on the plurality of values to be transmitted to obtain pre-compensated initial signal information. A cyclic prefix is appended to the pre-compensated initial signal information to form an OFDM symbol for transmission from the non-reference transceiver to the UE.
