Signaling lack of full spherical coverage in user equipments

An antenna apparatus comprising:

• a first antenna module configured to operate in a first operating frequency, wherein a first spherical coverage region around the first antenna module comprises one or more first coverage holes, and wherein each first coverage hole indicates a range of angles of the first spherical coverage region within which a gain provided by the first antenna module is below a configured signal strength threshold;
• and
• a second antenna module configured to operate in the first operating frequency, wherein a second spherical coverage region around the second antenna module comprises one or more second coverage holes, wherein each second coverage hole indicates a range of angles of the second spherical coverage region within which a gain provided by the second antenna module is below the configured signal strength threshold, and
• wherein a center axis of the second antenna module is offset from a center axis of the first antenna module to reduce overlap of the one or more first coverage holes and the one or more second coverage holes.

A user equipment (UE), comprising:

• one or more memories;
• one or more transceivers;
• and
• one or more processors communicatively coupled to the one or more memories and the one or more transceivers, the one or more processors, either alone or in combination, configured to:
• transmit, via the one or more transceivers, to a network entity, a capability message indicating one or more coverage holes in a spherical coverage region around the UE, wherein the spherical coverage region around the UE is realized with one or more antenna modules of the UE, and wherein each coverage hole indicates a range of angles of the spherical coverage region within which a gain provided by the one or more antenna modules is below a configured first signal strength threshold;
• and
• receive, via the one or more transceivers, from the network entity, a configuration of one or more reference signal resources to be measured by the one or more antenna modules in at least one coverage hole of the one or more coverage holes, wherein a density of the one or more reference signal resources is greater than a density of reference signal resources to be measured within the spherical coverage region outside the one or more coverage holes.
