Definitions

  • Figs. 3(a)-3(c) show examples of common subcarrier spacing of 12.5 kHz in
  • OFDMA numerology is the base of OFDM technology and directly affects the frame structure design, which is one of the basic elements of the Physical Layer. Various problems are caused by OFDMA numerology used by legacy system and their effect on current legacy system. The following table describes the basic OFDMA numerology defined by current legacy system:
  • Type 1 and Type 2 frame structures the concept of lots is only used to describe the dimensions of various resource blocks.
  • 10 subframes are available for downlink transmission and 10 subframes are available for uplink transmissions in each 10 ms interval.
  • Each subframe duration is 1 ms.
  • Uplink and downlink transmissions are separated in the frequency domain.
  • a 5-ms frame is made of multiple slots.
  • a regular frame contains up to 10 slots.
  • the concept of slots is used to describe the dimensions of resource blocks.
  • Each slot contains 6 OFDM symbols.
  • FDD Frequency Division Duplex
  • all frames are available for downlink transmission and all frames are available for uplink transmissions in each 20 ms superframe interval. Uplink and downlink transmissions are separated in the frequency domain.
  • Fig. 17 shows an exemplary illustration of deployment with mixed base stations 102 and mobile stations 104, according to an embodiment.
  • the present disclosure is not limited to any particular number or type of base stations 102 or mobile station 104.
  • memory or other storage may be employed in embodiments of the invention.
  • memory or other storage may be employed in embodiments of the invention.
  • any suitable distribution of functionality between different functional units, processing logic elements or domains may be used without detracting from the invention.
  • functionality illustrated to be performed by separate processing logic elements, or controllers may be performed by the same processing logic element, or controller.
  • references to specific functional units are only to be seen as references to suitable means for providing the described functionality, rather than indicative of a strict logical or physical structure or organization.
