Abstract:
1. A method, comprising: selecting a pattern in time-frequency domain, wherein the pattern in time-frequency domain assigns a modulation symbol to each frequency tone in a block of time-frequency resources, wherein the selecting includes acquiring from a memory at least one of a first pattern for a radio sub-frame structure with a normal cyclic prefix (CP), a second pattern for a radio sub-frame structure with an extended CP, or a third pattern for a multicast/broadcast single frequency network (MBSFN) sub-frame, wherein the first pattern, the second pattern, and the third pattern are specific to a coverage cell in a cellular telecommunication system; mapping a positioning reference signal (PRS) sequence to a set of modulation symbols in time-frequency domain according to at least the pattern; and conveying the PRS sequence through delivery of the set of modulation symbols.
