Beam sweep or scan in a wireless communication system
First Claim
1. A method performed by a user equipment configured for use in a wireless communication system, the method comprising:
- detecting an orientation of an equipment coordinate frame defined for the user equipment relative to an earth coordinate frame defined for Earth;
determining, based on the detected orientation, a set of beams defined in the equipment coordinate frame which does not include any beam pointing in one or more predefined directions in the earth coordinate frame,wherein determining the set of beams comprises selecting the set of beams from multiple sets of beams predefined for different detectable orientations of the equipment coordinate frame relative to the earth coordinate frame, andwherein each of the multiple sets of beams does not include any beam pointing in the one or more predefined directions in the earth coordinate frame; and
performing a beam sweep or scan on the determined set of beams.

Abstract
A user equipment is configured for use in a wireless communication system. The user equipment in this regard is configured to detect an orientation of an equipment coordinate frame defined for the user equipment relative to an earth coordinate frame defined for Earth. The user equipment is also configured to determine, based on the detected orientation, a set) of beams defined in the equipment coordinate frame which does not include any beam pointing in one or more predefined directions in the earth coordinate frame. The user equipment is further configured to perform a beam sweep or scan on the determined set of beams.

16. A user equipment configured for use in a wireless communication system, the user equipment comprising:
processing circuitry and a memory, the memory-containing instructions executable by the processing circuitry whereby the user equipment is configured to; detect an orientation of an equipment coordinate frame defined for the user equipment relative to an earth coordinate frame defined for Earth; determine, based on the detected orientation, a set of beams defined in the equipment coordinate frame which does not include any beam pointing in one or more predefined directions in the earth coordinate frame by selecting the set of beams from multiple sets of beams predefined for different detectable orientations of the equipment coordinate frame relative to the earth coordinate frame, wherein each of the multiple sets of beams does not include any beam pointing in the one or more predefined directions in the earth coordinate frame; and perform a beam sweep or scan on the determined set of beams. - View Dependent Claims (17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30)

31. A non-transitory computer readable medium having stored thereon a computer program that, when executed by processing circuitry of a user equipment configured for use in a wireless communication system, causes the user equipment to:
-
detect an orientation of an equipment coordinate frame defined for the user equipment relative to an earth coordinate frame defined for Earth; determine, based on the detected orientation, a set of beams defined in the equipment coordinate frame which does not include any beam pointing in one or more predefined directions in the earth coordinate frame by selecting the set of beams from multiple sets of beams predefined for different detectable orientations of the equipment coordinate frame relative to the earth coordinate frame, wherein each of the multiple sets of beams does not include any beam pointing in the one or more predefined directions in the earth coordinate frame; and perform a beam sweep or scan on the determined set of beams. - View Dependent Claims (32, 33)
