Abstract
An apparatus comprising: an antenna array comprising a plurality of antenna elements configured for receiving multiple input multiple output (MIMO) signals. The antenna array comprises at least a first subpart of the antenna array comprising a first subsection of the plurality of antenna elements. A second subpart of the antenna array comprises a second subsection of the plurality of antenna elements. An alignment of the antenna elements in the second subpart deviates substantially by 30°-60° from an alignment of the antenna elements in the first subpart.
Claims14
An apparatus, comprising:
- an antenna array comprising a plurality of antenna elements configured for receiving multiple input multiple output (MIMO) signals at a frequency, wherein the antenna array comprises at least:
- a first subpart of the antenna array comprising a first subsection of the plurality of antenna elements;
- a second subpart of the antenna array comprising a second subsection of the plurality of antenna elements, wherein an alignment of the antenna elements in the second subpart deviates substantially by 30°-60° from an alignment of the antenna elements in the first subpart;
- and
- circuitry configured to:
- determine a value of at least one quality metric for a received multiple input multiple output (MIMO) signal;
- compare the determined value of the at least one quality metric to a corresponding threshold value;
- and
- determine, based on the result of the comparison of the value of the at least one quality metric, whether to use the full antenna array or either the first or the second subpart of the antenna array for receiving the signals at the frequency.
A method, comprising:
- determining a value of at least one quality metric for a received multiple input multiple output (MIMO) signal at a frequency;
- comparing the determined value of the at least one quality metric to a corresponding threshold value;
- and
- determining, based on the result of the comparison of the value of the at least one quality metric, whether to use a full antenna array comprising a plurality of antenna elements or either a first subpart of the antenna array comprising a first subsection of the plurality of antenna elements or a second subpart of the antenna array comprising a second subsection of the plurality of antenna elements, wherein an alignment of the antenna elements in the second subpart deviates substantially by 30°-60° from an alignment of the antenna elements in the first subpart for receiving the signal at the frequency.
An apparatus, comprising:
- at least one processor;
- and
- at least one memory including computer program code, the at least one memory and the computer program code being configured to, with the at least one processor, cause the apparatus at least to:
- determine a value of at least one quality metric for a received multiple input multiple output (MIMO) signal at a frequency;
- compare the determined value of the at least one quality metric to a corresponding threshold value;
- and
- determine, based on the result of the comparison of the value of the at least one quality metric, whether to use a full antenna array comprising a plurality of antenna elements or either a first subpart of the antenna array comprising a first subsection of the plurality of antenna elements or a second subpart of the antenna array comprising a second subsection of the plurality of antenna elements, wherein an alignment of the antenna elements in the second subpart deviates substantially by 30°-60° from an alignment of the antenna elements in the first subpart for receiving the signal at the frequency.
