Abstract
Systems, methods, apparatuses, and computer program products for using angle error groups (AEGs) to improve angle of arrival (AoA) positioning may be provided. For example, for a specific received signal, one or more receiving antenna elements that can be considered to have almost the same incident angle within a certain margin may be defined as a group. The group of receive (Rx) antenna elements (or a group of Rx antennas) may be defined as an AEG. The configuration of an AEG for each TRP and the AEG may be used for AoA measurement and reporting. The gNB or transmit receive point (TRP) may perform AoA measurements and may determine an AoA for the AEGs.
Claims23
An apparatus, comprising:
- at least one processor;
- and
- at least one memory including computer program code,
- wherein the at least one memory and the computer program code are configured to, with the at least one processor, cause the apparatus at least to:
- transmit, to a node, information related to two or more angle error groups, wherein the two or more angle error groups comprise one or more antenna elements, wherein the information comprises identifiers for the two or more angle error groups;
- perform one or more angle of arrival measurements based on signals received at at least one angle error group of the two or more angle error groups;
- determine, based on the one or more angle of arrival measurements, an angle of arrival for the at least one angle error group;
- and
- transmit, to the node, the determined angle of arrival and an identifier for the at least one angle error group associated with the determined angle of arrival for determination of a user equipment location.
An apparatus, comprising:
- at least one processor;
- and
- at least one memory including computer program code,
- wherein the at least one memory and the computer program code are configured to, with the at least one processor, cause the apparatus at least to:
- receive, from a node, information related to two or more angle error groups, wherein the two or more angle error groups comprise one or more antenna elements, wherein the information comprises identifiers for the two or more angle error groups;
- and
- receive a determined angle of arrival related to signals received at at least one angle error group of the two or more angle error groups and an identifier for the at least one angle error group associated with the determined angle of arrival;
- and
- estimate a user equipment location based on the determined angle of arrival and the identifier.
A method, comprising:
- transmitting, by a node to another node, information related to two or more angle error groups, wherein the two or more angle error groups comprise one or more antenna elements, wherein the information comprises identifiers for the two or more angle error groups;
- performing one or more angle of arrival measurements based on signals received at at least one angle error group of the two or more angle error groups;
- determining, based on the one or more angle of arrival measurements, an angle of arrival for the at least one angle error group;
- and
- transmitting, to the other node, the determined angle of arrival and an identifier for the at least one angle error group associated with the determined angle of arrival for determination of a user equipment location.
