26 Claims

1. A UE (user equipment) comprising:

a body that is movable to a plurality of physical states having different physical arrangements with distinct portions of the body having different spatial relationships relative to each other in different ones of the plurality of physical states;

a transceiver including an antenna system comprising at least one antenna element;

a memory; and

a processor communicatively coupled to the transceiver and the memory and configured to:

determine a dynamic change of the UE from a first physical state of the plurality of physical states to a second physical state of the plurality of physical states with distinct portions of the body of the UE having different spatial relationships relative to each other in the first physical state of the plurality of physical states and the second physical state of the plurality of physical states; and

transmit, via the transceiver to a network entity and based on a determination of the dynamic change of the UE from a first physical state of the plurality of physical states to a second physical state of the plurality of physical states, a notification of one or more antenna system characteristics of the second physical state of the plurality of states based on the dynamic change of the body from the first physical state of the plurality of physical states to the second physical state of the plurality of physical states;

wherein the antenna system has a plurality of radiation patterns that are different from each other and that each correspond to one or more of the plurality of physical states, and the notification comprises a radiation pattern indication indicating at least one of the plurality of radiation patterns.

11. A method at a UE (user equipment) for indicating change in physical state of the UE, the method comprising:

determining a dynamic change of the UE from a first physical state of a plurality of physical states to a second physical state of the plurality of physical states with distinct portions of a body of the UE having different spatial relationships relative to each other in the first physical state of the plurality of physical states and the second physical state of the plurality of physical states; and

transmitting, from the UE to a network entity and based on a determination of the dynamic change of the UE from a first physical state of the plurality of physical states to a second physical state of the plurality of physical states, a notification of one or more antenna system characteristics of the second physical state of the plurality of states, corresponding to an antenna system of the UE, based on determining the dynamic change of the UE from the first physical state of the plurality of physical states to the second physical state of the plurality of physical states;

21. A UE (user equipment) comprising:

means for determining a dynamic change of the UE from a first physical state of a plurality of physical states to a second physical state of the plurality of physical states with distinct portions of a body of the UE having different spatial relationships relative to each other in the first physical state of the plurality of physical states and the second physical state of the plurality of physical states; and

means for transmitting, from the UE to a network entity and based on a determination of the dynamic change of the UE from a first physical state of the plurality of physical states to a second physical state of the plurality of physical states, a notification of one or more antenna system characteristics of the second physical state of the plurality of states, corresponding to an antenna system of the UE, based on determining the dynamic change of the UE from the first physical state of the plurality of physical states to the second physical state of the plurality of physical states;

26. A non-transitory, processor-readable storage medium comprising processor-readable instructions to cause a processor of a UE (user equipment) to:

determine a dynamic change of the UE from a first physical state of a plurality of physical states to a second physical state of the plurality of physical states with distinct portions of a body of the UE having different spatial relationships relative to each other in the first physical state of the plurality of physical states and the second physical state of the plurality of physical states; and

transmit, from the UE to a network entity and based on a determination of the dynamic change of the UE from a first physical state of the plurality of physical states to a second physical state of the plurality of physical states, a notification of one or more antenna system characteristics of the second physical state of the plurality of states, corresponding to an antenna system of the UE, based on determining the dynamic change of the UE from the first physical state of the plurality of physical states to the second physical state of the plurality of physical states;
