By a News Reporter-Staff News Editor at Telecommunications Weekly -- From Alexandria, Virginia, VerticalNews journalists report that a patent by the inventor Nieman, Karl F. (Austin, TX), filed on September 30, 2015, was published online on May 16, 2017.
The patent's assignee for patent number 9654188 is NATIONAL INSTRUMENTS CORPORATION (Austin, TX).
News editors obtained the following quote from the background information supplied by the inventors: "Technical Field
"This disclosure relates to wireless communication systems and more particularly to multiple input, multiple output (MIMO) communications.
"Description of the Related Art
"Modern communication systems rely upon multiple antennas at the transmitter and/or receiver to enhance link performance. This class of techniques, known as multiple input, multiple output (MIMO) exploits the spatial dimension by employing spatial encoding and/or decoding. Massive MIMO is an exciting area of 5G wireless research that promises significant gains that offer the ability to accommodate more users, at higher data rates, with better reliability, while consuming less power. Conventional MIMO base stations typically use six or eight antennas in a sectorized topology, but massive MIMO base stations utilize more than eight antennas (and sometimes as many as 128, 256, or more) and massive MIMO user equipment devices (UEs) may typically utilize around eight antennas. Using the larger number of antenna elements, massive MIMO reduces power in a given channel by focusing the energy to targeted mobile users using precoding techniques. By directing the wireless energy to specific users, the power in channel is reduced and, at the same time, interference to other users is decreased.
"The introduction of so many antenna elements, however, introduces several system challenges not encountered in conventional networks. For example, processing and synchronization requirements for massive MIMO may be difficult to meet using conventional systems. Therefore both test systems for prototyping different MIMO techniques and production MIMO systems configured to utilize these techniques are desired."
As a supplement to the background information on this patent, VerticalNews correspondents also obtained the inventor's summary information for this patent: "Techniques are disclosed relating to massive MIMO communications. In some embodiments, a base station is configured to dynamically adjust the number of processing elements used for MIMO signal estimation (e.g., the number of MIMO RX chains used for parallel processing). In some embodiments, the base station is configured to scale from only a few antennas to as many as 128, 256, etc. In some embodiments, the number of processing elements may be based on the number of antennas currently being used, the number of spatial streams, interconnect throughput thresholds, sampling rates, etc. In some embodiments, the base station includes MIMO processing cores that are configured to dynamically switch between MIMO signal estimation techniques, e.g., on a per-symbol basis. In some embodiments, the base station includes configurable linear decoders configured to separately multiply input matrices and combine (or refrain from combining) the results based on the number of antennas and/or processing elements currently in use."
