    摘要： To increase positioning accuracy, channel characteristics are determined taking into account receive filter response and transmit filter response. For example, upon receiving assistance data for positioning an apparatus, a transmit sequence is generated using the assistance data; and a combination of the transmit sequence is generated by combining the transmit sequence. Further, a receive filter response is determined, a transmit filter response is obtained, and a combined filter response is generated using the receive filter response and the transmit filter response. Reference signals received over a channel are measured by sampling them into a plurality of time-domain samples, and the channel is estimated from the plurality of time-domain samples using the combined filter response and the combination of the transmit sequence. Then, per a channel characteristics, a value of the channel characteristics based on the channel estimated is determined.

    摘要： A method includes obtaining a first power measurement associated with resource blocks (RBs) being utilized by a terminal device (TD). The method includes determining whether the first power measurement satisfies a first threshold. The method includes, upon determining that the first power measurement satisfies the first threshold, transmitting, to a target TD, a positioning reference signal (PRS). The method includes, determining whether the first power measurement does not satisfy the first threshold and, in response, determining a set of comb parameters. The method includes obtaining, based on the set of comb parameters, a second power measurement associated with resource elements (REs) related to the RBs. The method includes determining whether the second power measurement satisfies a second threshold. The method includes, upon determining that the second power measurement satisfies the second threshold, transmitting, based on the set of comb parameters, the PRS to the target TD.

    摘要： There is provided an apparatus comprising: at least one processor; and at least one memory storing instructions that, when executed by the at least one processor, cause the apparatus, which is configured to perform sidelink positioning with another apparatus, at least to perform: transmitting, to the other apparatus, an indication that a sidelink positioning reference signal, SL PRS, resource transmission, which the apparatus is configured to transmit, comprises at least one de-modulation reference signal, DMRS, symbol; and generating a sequence of a SL PRS resource transmission comprising: a SL PRS sequence; and a DMRS sequence comprising at least one DMRS symbol; and transmitting the sequence of the SL PRS resource transmission at least to the other apparatus.
