Embodiment Construction

[0026] In summary, various aspects described herein relate to associating a downlink reference signal for positioning a user equipment with an uplink reference signal for transmission by the user equipment. In one embodiment, as part of a positioning procedure for a user equipment (UE), a network entity (e.g., base station, core network component, etc.) schedules at least one downlink (DL) transmission by at least one base station to the UE. A first set of resources for reference signals (RS). As part of the positioning procedure for the UE, the network entity associates at least one DL RS with at least one uplink (UL) RS for transmission by the UE to the one or more base stations on the second set of resources, and sends The UE sends an indication of an association between at least one DL RS and at least one UL RS. The UE receives the indication and at least one DL RS from at least one base station on the first set of resources. In response to the received indication, the U...

Abstract

In an embodiment, a network entity schedules, as part of a positioning procedure for a UE, a first set of resources for transmission of DL RS(s) by at least one BS to the UE. The network entity associates the DL RS(s) with UL RS(s) for transmission by the UE on a second set of resources to one or more BSs as part of the positioning procedure for the UE. The network entity transmits, to the UE, anindication of the association between the DL RS(s) and the UL RS(s). The UE receives the indication along with the DL RS(s) from the at least one BS. The UE transmits the UL RS(s) to the one or more BSs on the second set of resources in response to the received indication.
