U.S. Patent Publication No. 2023/0007619 - Prepared by Attorney David Tran for Qualcomm Incorporated and filed by Weaver (WAVS IP)
Brief Description: Disclosed are some examples of techniques for positioning of a user equipment (UE) using positioning reference signal (PRS). One or more units of messages may be communicated between an initiator UE and a responder UE. A unit of message may include a pre-PRS message, a PRS message and a post-PRS message. The pre-PRS message and the post-PRS message may be sent or received using a license spectrum. The PRS message may be sent or received using an unlicensed spectrum. The communication between the initiator UE and the responder UE may be initiated by the initiator UE identifying the responder UE from a plurality of UEs based on positioning properties of the responder UE. The positioning properties of the responder UE may include one or more of a direction, a velocity, a location confidence and a location of the responder UE. Examples of techniques for positioning of a user equipment (UE) using positioning reference signal (PRS) may be disclosed. An initiator UE may be configured to send or transmit one or more units of messages to a group of two or more responder UEs. A unit of message may include a pre-PRS message, a PRS message and a post-PRS message. Each of the responder UEs may be configured to transmit one or more units of messages to the initiator UE. The pre-PRS message and the post-PRS message may be transmitted using a license spectrum. The PRS message may be transmitted using an unlicensed spectrum. Using the unlicensed spectrum may enable a UE to have access to more bandwidth which may help improving positioning accuracy. The communication from the initiator UE to the group of responder UEs may be performed with the initiator UE broadcasting messages having the same payload to the responder UEs in the group of responder UEs. The communication from the responder UEs may be performed with each responder UE in the group of responder UEs broadcasting its messages to the initiator UE.
