Abstract

Aspects presented herein may enable a network node (e.g., a UE, a TRP/base station) to provide its beam squint information and/or to receive beam squint information of another positioning entity to improve the accuracy and reliability of UE positioning. In one aspect, a network node obtains beam squint information associated with a set of beams of the network node under a plurality of center frequencies. The network node transmits, for a network entity, the beam squint information for at least one beam of the set of beams for a positioning session. The network entity participates, based on the beam squint information via the at least one beam, in the positioning session with the network entity.

Dependent claims

An apparatus for wireless communication at a user equipment (UE), comprising:

at least one memory;
and
at least one processor coupled to the at least one memory, and the at least one processor is configured to:
obtain beam squint information associated with a set of beams of the UE under a plurality of center frequencies, wherein the beam squint information for each beam in the set of beams includes at least one of:
a set of equivalent isotropic radiated power (EIRP) measurements for the plurality of center frequencies under different angles, a first difference between the set of EIRP measurements of a reference center frequency in the plurality of center frequencies and one or more non-reference center frequencies in the plurality of center frequencies under the different angles, an angle of a maximum EIRP measurement for each center frequency in the plurality of center frequencies, a second difference between angles of maximum EIRP measurements of the reference center frequency in the plurality of center frequencies and the one or more non-reference center frequencies in the plurality of center frequencies, or a combination thereof;
receive, from a network entity, a request to provide the beam squint information;
transmit, for the network entity based on the request, the beam squint information for one or more beams in the set of beams;
and
perform, based on the beam squint information, positioning of the UE using at least one beam in the one or more beams.
