NR-light user equipment based positioning with round trip time procedure
Techniques for positioning a NR bandwidth-limited user equipment (UE) are provided. An example method of positioning performed by a bandwidth-limited UE includes transmitting a first timing measurement signal to at least one proximate premium UE, wherein the at least one proximate premium UE is capable of using more bandwidth than the bandwidth-limited UE, receiving a second timing measurement signal from the at least one proximate premium UE, and determining location information for the bandwidth-limited UE based at least on the first timing measurement signal and the second timing measurement signal.
1 . A method of positioning performed by a bandwidth-limited user equipment (UE), comprising:
determining that a premium UE is premium, and thus is capable of at least using more bandwidth than the bandwidth-limited UE, and is proximate to the bandwidth-limited UE;
transmitting, based on the premium UE being premium and being proximate to the bandwidth-limited UE, a first timing measurement signal from the bandwidth-limited UE to the premium UE;
receiving a second timing measurement signal from the premium UE at the bandwidth-limited UE; and
determining location information for the bandwidth-limited UE based at least on the first timing measurement signal and the second timing measurement signal.
2 . The method of claim 1 wherein determining the location information for the bandwidth-limited UE includes computing a distance to the premium UE with at least one processor in the bandwidth-limited UE.
3 . The method of claim 1 further comprising:
establishing a sidelink connection to the premium UE, wherein the first timing measurement signal and the second timing measurement signal are transmitted and received via the sidelink connection; and
receiving a current location of the premium UE via the sidelink connection.
4 . The method of claim 1 wherein determining that the premium UE is premium includes obtaining an identification for the premium UE from a base station, and the method further comprises establishing a sidelink connection to the premium UE, wherein the first timing measurement signal and the second timing measurement signal are transmitted and received via the sidelink connection.
5 . The method of claim 1 wherein determining that the premium UE is premium and is proximate to the bandwidth-limited UE includes receiving a measurement request message from the premium UE prior to transmitting the first timing measurement signal.
6 . The method of claim 1 further comprising transmitting location information to the premium UE.
7 . The method of claim 1 further comprising transmitting location information to a base station.
8 . The method of claim 1 wherein the first timing measurement signal and the second timing measurement signal utilize a channel state information reference signal.
9 . The method of claim 8 wherein the channel state information reference signal is within a physical sidelink control channel.
10 . A bandwidth-limited user equipment (UE), comprising:
a memory;
a transceiver;
at least one processor operably coupled to the memory and the transceiver, and configured to:
determine that a premium UE is premium, and thus is capable of at least using more bandwidth than the bandwidth-limited UE, and is proximate to the bandwidth-limited UE;
transmit, based on the premium UE being premium and being proximate to the bandwidth-limited UE, a first timing measurement signal to the premium UE;
receive a second timing measurement signal from the premium UE; and
determine location information for the bandwidth-limited UE based at least on the first timing measurement signal and the second timing measurement signal.
11 . The bandwidth-limited UE of claim 10 wherein the at least one processor is further configured to compute a distance to the premium UE.
12 . The bandwidth-limited UE of claim 10 wherein the at least one processor is further configured to:
establish a sidelink connection to the premium UE, and to transmit the first timing measurement signal and to receive the second timing measurement signal via the sidelink connection; and
receive a current location of the premium UE via the sidelink connection.
13 . The bandwidth-limited UE of claim 10 wherein the at least one processor is further configured to:
obtain an identification for the premium UE from a base station to determine that the premium UE is premium; and
establish a sidelink connection to the premium UE, and to transmit the first timing measurement signal and to receive the second timing measurement signal via the sidelink connection.
14 . The bandwidth-limited UE of claim 10 wherein to determine that the premium UE is premium and is proximate to the bandwidth-limited UE the at least one processor is further configured to receive a measurement request message from the premium UE.
15 . The bandwidth-limited UE of claim 10 wherein the at least one processor is further configured to transmit the location information to the premium UE.
16 . The bandwidth-limited UE of claim 10 wherein the at least one processor is further configured to transmit the location information to a base station.
17 . The bandwidth-limited UE of claim 10 wherein the at least one processor is further configured to utilize a channel state information reference signal for the first timing measurement signal and the second timing measurement signal.
18 . The bandwidth-limited UE of claim 17 wherein the channel state information reference signal is within a physical sidelink control channel.
19 . A bandwidth-limited user equipment (UE), comprising:
means for determining that a premium UE is premium, and thus is capable of at least using more bandwidth than the bandwidth-limited UE, and is proximate to the bandwidth-limited UE;
means for transmitting, based on the premium UE being premium and being proximate to the bandwidth-limited UE, a first timing measurement signal to the premium UE;
means for receiving a second timing measurement signal from the premium UE; and
means for determining location information for the bandwidth-limited UE based at least on the first timing measurement signal and the second timing measurement signal.
