Radio network node and method for using positioning gap indication for enhancing positioning performance

摘要

A wireless communications network is described herein in which positioning measurements (e.g., inter-frequency OTDOA measurements and inter-frequency E-CID measurements) may be performed on different frequencies and measurement gaps may be requested for such measurements. In one embodiment, a radio network node (e.g., eNodeB, responsible node) is described for configuring a measurement gap for positioning to be used by a user equipment (UE).

1. A radio network node for configuring a measurement gap for positioning to be used by a user equipment (UE), the radio network node comprising:
a memory configured to store processor-executable instructions; and a processor configured to interface with the memory and, by executing the processor-executable instructions, to:
receive an indication from the UE indicating that the UE needs measurement gaps for positioning;verify parameters in the indication to determine if one or more pre-defined conditions are met to indicate that the UE is able to perform inter-frequency positioning measurements;decide whether to configure the measurement gaps,in response to deciding to configure the measurement gaps, determine a measurement gap configuration and send the measurement gap configuration to the UE; perform at least one of deciding whether to configure the measurement gaps and verifying the parameters based on internal measurements or information obtained from a co-located node or via cross-layer communication; and wherein the memory and processor are components of the radio network node.
