Abstract
Disclosed are techniques for transmitting and receiving an extended narrowband positioning reference signal (NPRS) sequence. In an aspect, a base station generates the extended NPRS sequence and transmits, to at least one user equipment (UE) over a wireless narrowband channel, the extended NPRS sequence. In an aspect, a UE receives, over the wireless narrowband channel, an NPRS of a first subset of the extended NPRS sequence and measures the NPRS of the first subset of the extended PRS sequence. In an aspect, the extended NPRS sequence may be a function of a plurality of slot numbers of a plurality of slots of a plurality of sequential radio frames and a plurality of symbol indexes of a plurality of symbols of a single physical resource block.
