Problems solved by technology

Since each antenna element in a digital beamforming system requires a dedicated RF chain, many digital beamforming solutions can be hardware intensive and thus have significant cost and power consumption rates

Embodiment Construction

[0020] The following detailed description refers to the accompanying drawings, which show, by way of illustration, specific details and embodiments in which the invention may be practiced.

[0021] The word "exemplary" is used herein to mean "serving as an example, instance, or illustration." Any embodiment or design described herein as "exemplary" is not necessarily to be construed as preferred or advantageous over other embodiments or designs.

[0022] The word "plurality" in the description and claims explicitly refers to a number greater than one. Thus, any phrase that explicitly invokes the above words to refer to a number of objects (eg, "a plurality of [objects]") unambiguously refers to more than one of said objects. The terms "(of) group", "( of) set", "( of) collection", "( of) series", "( of) sequence", "( of) grouping", etc. are used in the specification and claims (if any) means a quantity equal to or greater than 1, ie one or more. The terms "appropriate subse...

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.

Description

technical field [0001] Various embodiments relate generally to steering of modular antenna arrays. Background technique [0002] Antenna-based communication systems can utilize beamforming to create steered antenna beams with an antenna array. A beamforming system may adjust the delay and / or gain of each of the signals transmitted through (or received in a receive direction) elements of the antenna array to produce constructively and destructively inferred patterns in certain angular directions. By precisely selecting the delay and gain of each antenna element, the beamforming architecture can control the resulting interference pattern in order to achieve a steerable "main lobe" that provides high beam gain in a specific direction. Many beamforming systems can allow adaptive control of the beam pattern by dynamically adjusting the delay and gain parameters of each antenna element, and thus can allow the beamformer to constantly adjust the steering direction of the beam in o...
