A method for reducing effects of motion of a mobile device on wireless position measurement signals over a wireless communication network, the method comprising: defining a subcarrier frequency spacing for dividing a predetermined frequency band into a plurality of subcarrier frequency bands; the method characterised by determining a symbol length in a time domain, wherein the symbol length is greater than a minimum symbol length determined based on the subcarrier frequency spacing, wherein the minimum symbol length is based on an inverse of the subcarrier frequency spacing; sending instructions to a first base station to transmit, on a first subcarrier frequency band of the plurality of subcarrier frequency bands, at least a portion of a first wireless position measurement signal during a symbol of the symbol length, wherein the at least the portion of the first wireless position measurement signal has a first sinc-shaped function in a frequency domain, and wherein the first sinc-shaped function has a plurality of ordered null points as frequency increases past a main lobe of the first sine-shaped function; and sending instructions to a second base station to transmit, on a second subcarrier frequency band of the plurality of subcarrier frequency bands, at least a portion of a second wireless position measurement signal during the symbol, wherein the second subcarrier frequency band is adjacent to the first subcarrier frequency band, and wherein the at least the portion of the second wireless position measurement signal has a second sinc-shaped function in the frequency domain, and wherein a main lobe of the second sinc-shaped function is at a null point of the first sinc-shaped function after a first ordered null point of the first sine-shaped function. defining a subcarrier frequency spacing for dividing a predetermined frequency band into a plurality of subcarrier frequency bands; the method characterised by determining a symbol length in a time domain, wherein the symbol length is greater than a minimum symbol length determined based on the subcarrier frequency spacing, wherein the minimum symbol length is based on an inverse of the subcarrier frequency spacing; sending instructions to a first base station to transmit, on a first subcarrier frequency band of the plurality of subcarrier frequency bands, at least a portion of a first wireless position measurement signal during a symbol of the symbol length, wherein the at least the portion of the first wireless position measurement signal has a first sinc-shaped function in a frequency domain, and wherein the first sinc-shaped function has a plurality of ordered null points as frequency increases past a main lobe of the first sine-shaped function; and sending instructions to a second base station to transmit, on a second subcarrier frequency band of the plurality of subcarrier frequency bands, at least a portion of a second wireless position measurement signal during the symbol, wherein the second subcarrier frequency band is adjacent to the first subcarrier frequency band, and wherein the at least the portion of the second wireless position measurement signal has a second sinc-shaped function in the frequency domain, and wherein a main lobe of the second sinc-shaped function is at a null point of the first sinc-shaped function after a first ordered null point of the first sine-shaped function. <EOS>
