NON-INTEGER MULTIPLE QUANTITIES OF TRANSMIT AND RECEIVE ANTENNA SUBARRAYS
Document Type and Number:
WIPO Patent Application WO/2023/159467
Kind Code:
A1
Abstract:
Methods, systems, and devices for wireless communication are described. In some systems, a first device may include a first circular antenna array including a first quantity of antenna subarrays. A second device may include a second circular antenna array including a second quantity of antenna arrays. Each antenna subarray may include one or more antenna elements. The first device may transmit one or more reference signals to the second device. The second device may transmit a feedback message to the first device based on the reference signals. The feedback message may include an indication of sets of beamforming weights or information for determining the sets of beamforming weights based on the second quantity of antenna subarrays being different than the first quantity of antenna subarrays. The first device may transmit one or more signals concurrently to the second device based on the sets of beamforming weights.
