Abstract: First incoming data comprising at least one OFDM symbol is received (302). A plurality of timing relationships is determined and each of the plurality of timing relationships relates to an alignment window of a fast Fourier transform (FFT) (304). Each of the plurality of timing relationships is applied to the first incoming data (306) and a plurality of achievable interference metrics associated with the first incoming data is responsively determined (308). Each of the plurality of achievable interference metrics is associated with a selected one of the plurality of timing relationships. The preferred interference metric is chosen from amongst the plurality of achievable interference metrics.

Abstract: A base station communicates a positioning reference signal (PRS) to wireless communication devices over a downlink in a wireless communication system by encoding a PRS into a first set of transmission resources, encoding other information into a second set of transmission resources, multiplexing the two sets of resources into a subframe such that the first set of resources is multiplexed into at least a portion of a first set of orthogonal frequency division multiplexed (OFDM) symbols based on an identifier associated with the base station and the second set of resources is multiplexed into a second set of OFDM symbols. Upon receiving the subframe, a wireless communication device determines which set of transmission resources contains the PRS based on the identifier associated with the base station that transmitted the subframe and processes the set of resources containing the PRS to estimate timing (e.g., time of arrival) information.

Abstract: An interference contribution associated with a selected subcarrier of a plurality of subcarriers associated with a previously transmitted OFDM symbol or a current OFDM symbol is determined (300). A fast Fourier transform (FFT) output for the current OFDM symbol is also determined (304). The interference contribution is subtracted from the FFT output of the current OFDM symbol to form a modified FFT output (308).
