Abstract
Disclosed is a method of configuring a Positioning Reference Signal, PRS, in each of a plurality of cells in a telecommunication network. The method of a serving base station (BS) may include transmitting a second positioning reference signal (PRS) to a user equipment (UE); receiving, from the UE, a request to request a neighbor BS to configure a first PRS to occupy (1/μ)th of slot duration of a Sub Carrier Spacing (SCS) of the neighbor BS; and transmitting the request to the neighbor BS, wherein the neighbor BS having a lower (SCS) than an SCS of the serving BS, and wherein μ is the ratio of the SCS of the serving BS to the SCS of the neighbor BS.
Claims16
1-15. (canceled)
A user equipment (UE) in a wireless communication system, the UE comprising:
- a transceiver;
- and
- at least one processor operably connected to the transceiver, the at least one processor configured to:
- control the transceiver to receive a first positioning reference signal (PRS) from a first cell and a second PRS from a second cell,
- identify that a first Sub Carrier Spacing (SCS) of the first cell is lower than a second SCS of the second cell based on the first PRS and the second PRS, and
- control the transceiver to transmit, to the second cell, a request message to request the first cell to configure the first PRS having the same slot duration as a slot duration of the second PRS.
A second cell in a wireless communication system, the second cell comprising:
- a transceiver;
- and
- at least one processor operably connected to the transceiver, the at least one processor configured to:
- control the transceiver to transmit a second positioning reference signal (PRS) to a user equipment (UE),
- control the transceiver to receive, from the UE, a request message to request a first cell to configure a first PRS having the same slot duration as a slot duration of the second PRS, wherein a first PRS is transmitted by the first cell, and
- control the transceiver to transmit, to the first cell, a request for configuring the first PRS having the same slot duration as a slot duration of the second PRS based on the request message,
- wherein a first Sub Carrier Spacing (SCS) of the first cell is lower than a second SCS of the second cell.
A first cell in a wireless communication system, the first cell comprising:
- a transceiver;
- and
- at least one processor operably connected to the transceiver, the at least one processor configured to:
- control the transceiver to transmit a first positioning reference signal (PRS) to a user equipment (UE),
- control the transceiver to receive, from a second cell, a request for configuring the first PRS having the same slot duration as a slot duration of a second PRS based on the request message, wherein the second PRS is transmitted by the second cell, and
- determine a slot duration of the first PRS based on the request to be same as the slot duration of the second PRS,
- wherein a first Sub Carrier Spacing (SCS) of the first cell is lower than a second SCS of the second cell.
