Abstract

A user equipment includes at least one processor and at least one memory including computer program code. The at least one memory and the computer program code are configured to, with the at least one processor, cause the user equipment to: select radio resources for a first sidelink transmission to a first user equipment based on sidelink control information from a second user equipment, the sidelink control information including at least beam information for a second sidelink transmission by the second user equipment; and perform the first sidelink transmission to the first user equipment on the selected radio resources.

First claim

What is claimed is:

1. A user equipment comprising:
at least one processor; and
at least one memory including computer program code, the at least one memory and the computer program code configured to, with the at least one processor, cause the user equipment to
receive beamforming and interference rejection capability information for a first user equipment, wherein the beamforming and interference rejection capability information indicates whether the first user equipment is capable of performing beamforming and interference rejection,
select radio resources for a first sidelink transmission to the first user equipment based on the beamforming and interference rejection capability information and sidelink control information from a second user equipment, the sidelink control information including at least beam information for a second sidelink transmission by the second user equipment,
wherein the sidelink control information includes at least one of beam width or beam direction for the second sidelink transmission and the beam direction is in one or two dimensions, and
perform the first sidelink transmission to the first user equipment on the selected radio resources.

2. The user equipment of claim 1 , wherein
the sidelink control information is included in first stage sidelink control information, second stage sidelink control information, or a MAC control element.

3. The user equipment of claim 1 , wherein the sidelink control information includes beam width and beam direction for the second sidelink transmission, and the beam width and beam direction for the second sidelink transmission are encoded in a beam width and direction field of the sidelink control information.

4. The user equipment of claim 2 , wherein the second stage sidelink control information includes position information for the second user equipment, the position information being indicated by a Zone ID field of the second stage sidelink control information.

5. The user equipment of claim 1 , wherein the second sidelink transmission is from the second user equipment to a third user equipment.

6. A method for sidelink transmission from a first user equipment to a second user equipment, the method comprising:
receiving, at the first user equipment, beamforming and interference rejection capability information for the second user equipment, wherein the beamforming and interference rejection capability information indicates whether the second user equipment is capable of performing beamforming and interference rejection,
selecting, at the first user equipment, radio resources for a first sidelink transmission to the second user equipment based on the beamforming and interference rejection capability information and sidelink control information from a third user equipment, the sidelink control information including at least beam information for a second sidelink transmission by the third user equipment,
wherein the sidelink control information includes at least one of beam width or beam direction for the second sidelink transmission and the beam direction is in one or two dimensions, and
performing the first sidelink transmission from the first user equipment to the second user equipment on the selected radio resources.
