1. A method for position determining, performed by a communication system comprising a first user equipment (UE) and a base station, and the method comprising:
sending, by the first UE, a first ranging request to a base station, wherein the first ranging request carries an identifier associated with a second UE, wherein the first ranging request is at least associated with a ranging between the base station and the second UE; and
receiving, by the first UE, first range information associated with the first range request from the base station;
wherein the method further comprises:
receiving, by the base station, the first ranging request from the first UE; and
sending, by the base station, first range information to the first UE in response to the first range request;
wherein the method further comprises:
obtaining, by the base station, the relative position between the second UE and the base station by performing the ranging between the base station and the second UE according to the first ranging request;
wherein obtaining by the base station the relative position between the second UE and the base station by performing the ranging between the base station and the second UE comprises:
sending, by the base station, a second ranging request to the second UE; and
receiving, by the base station, fourth ranging information associated with the second ranging request from the second UE, wherein the fourth ranging information is configured to indicate the relative position between the second UE and the base station.
