Definitions

  • FIG. 5 illustrates a block diagram of example operations for wireless communications by an apparatus, in accordance with certain aspects of the present disclosure.
  • FIG. 5A illustrates example means capable of performing the operations shown in FIG. 5.
  • the operations 400 begin, at 402, by generating at least one sequence of pilots for one or more of a plurality of spatial streams of a multi user multiple input- multiple output (MIMO) transmission, wherein the at least one sequence of pilots is distinguishable from at least one other sequence of pilots transmitted by the apparatus or other apparatuses.
  • the station may output the sequence of pilots for transmission to a device in the MIMO transmission.
  • the example 20/40/80MHz transmissions referred to in the present disclosure may generally correspond to transmissions with lx symbol duration (i.e., as with 802.1 lac pilot transmissions), such that the corresponding number of pilots is 4 for 20 MHz, 6 for 40 MHz, and 8 for 80MHz.
  • a different symbol duration may be specified as the only operational mode, such as a 4x symbol duration specified in 802.1 lax.
  • the FFT size may be 4 times that of l lac with same bandwidth.
  • the 802.1 lax 20 MHz 4x tone plan may use the same number of pilots and data tones as 802.1 lac 80MHz tone plan (which uses a lx symbol duration).
  • the pilot mapping for 80MHz lx with 8 pilots may be directly used for 11 ax 20 MHz with 4x symbol duration.
  • DSP digital signal processor
  • ASIC application specific integrated circuit
  • FPGA field programmable gate array
  • PLD programmable logic device
  • a general- purpose processor may be a microprocessor, but in the alternative, the processor may be any commercially available processor, controller, microcontroller, or state machine.
  • Computer- readable media include both computer storage media and communication media including any medium that facilitates transfer of a computer program from one place to another.
  • a storage medium may be any available medium that can be accessed by a computer.
  • such computer-readable media can comprise RAM, ROM, EEPROM, CD-ROM or other optical disk storage, magnetic disk storage or other magnetic storage devices, or any other medium that can be used to carry or store desired program code in the form of instructions or data structures and that can be accessed by a computer.
  • any connection is properly termed a computer-readable medium.
