Abstract
The present application relates to devices and components including apparatus, systems, and methods for determining and/or implementing near-field operation or far-field operation for beamforming.
Claims20
A method comprising:
- determining first at least one layer 1 measurement for a first beam on a first set of sub-bands;
- determining second at least one layer 1 measurement for a second beam on a second set of sub-bands;
- and
- determining whether near-field operation or far-field operation is to be implemented for beamforming based at least in part on a ratio of the second at least one layer 1 measurement on the second set of sub-bands to the first at least one layer 1 measurement on the first set of sub-bands.
1 more element
A method comprising:
- identifying an indication whether a user equipment (UE) recommends switching between near-field operation and far-field operation for beamforming;
- and
- determining whether to initiate a switch between near-field operation and far-field operation based at least in part on the indication.
An apparatus comprising:
- processing circuitry to:
- identify a transmission configuration information (TCI) state configuration for beamforming, the TCI state configuration including a first set of TCI states corresponding to near-field operation and a second set of TCI states corresponding to far-field operation;
- identify a medium access control (MAC) control element (CE) that activates a sub-set of the first set of TCI states or the second set of TCI states;
- identify downlink control information (DCI) that indicates at least one TCI state for implementation from the sub-set;
- and
- implement near-field operation or far-field operation for beamforming in accordance with the at least one TCI state;
- and
- interface circuitry coupled with the processing circuitry, the interface circuitry to enable communication.
