Abstract
A radio communication device includes a plurality of antenna arrays each configured to generate a steerable antenna beam according to a respective beamforming codeword, wherein each of the plurality of antenna arrays is configured to obtain the respective beamforming codeword from a single-antenna-array steering codebook that is reused by each of the plurality of antenna arrays, and a beamforming circuit configured to weight signals for the plurality of antenna arrays to coordinate the steerable antenna beams from a subset of the plurality of antenna arrays to form a combined antenna beam in a first steering direction.
Claims25
A radio communication device comprising:
- a plurality of antenna arrays each configured to generate a steerable antenna beam according to a respective beamforming codeword, wherein each of the plurality of antenna arrays is configured to obtain the respective beamforming codeword from a single-antenna-array steering codebook that is reused by each of the plurality of antenna arrays;
- and
- a beamforming circuit configured to weight signals for the plurality of antenna arrays to coordinate the steerable antenna beams from a subset of the plurality of antenna arrays to form a combined antenna beam in a first steering direction.
A radio communication device comprising:
- a plurality of antenna arrays each comprising a plurality of intermediate frequency (IF) beamforming circuits and a plurality of radio frequency (RF) beamforming circuits, wherein the plurality of RF beamforming circuits are configured to steer an antenna beam for the corresponding antenna array according to a respective steering codeword and the plurality of IF beamforming circuits are configured to performing beam broadening on the antenna beam for the corresponding antenna array according to a respective broadening codeword;
- and
- a digital beamforming circuit configured to weight signals for the plurality of antenna arrays to coordinate the steerable antenna beams from a subset of the plurality of antenna arrays to form a combined antenna beam in a first steering direction.
A radio communication device comprising:
- a plurality of antenna arrays each configured to generate a steerable antenna beam according to a respective beamforming codeword, wherein each of the plurality of antenna arrays is configured to obtain the respective beamforming codeword from a single-antenna-array steering codebook that is common to each of the plurality of antenna arrays;
- and
- a beamforming circuit configured to weight signals for the plurality of antenna arrays to coordinate the steerable antenna beams from a subset of the plurality of antenna arrays independently of the respective beamforming codewords assigned to the plurality of antenna arrays to form a combined antenna beam in a first steering direction.
