Definitions

  • FIG. 8 is a diagram illustrating FDMA scheduling for multiple UEs using an adaptive beam width.
  • processors include microprocessors, microcontrollers, digital signal processors (DSPs), field programmable gate arrays (FPGAs), programmable logic devices (PLDs), state machines, gated logic, discrete hardware circuits, and other suitable hardware configured to perform the various functionality described throughout this disclosure.
  • DSPs digital signal processors
  • FPGAs field programmable gate arrays
  • PLDs programmable logic devices
  • state machines gated logic, discrete hardware circuits, and other suitable hardware configured to perform the various functionality described throughout this disclosure.
  • processors in the processing system may execute software.
  • Software shall be construed broadly to mean instructions, instruction sets, code, code segments, program code, programs, subprograms, software modules, applications, software applications, software packages, routines, subroutines, objects, executables, threads of execution, procedures, functions, etc., whether referred to as software, firmware, middleware, microcode, hardware description language, or otherwise.
  • the UE 102 may also be referred to by those skilled in the art as a mobile station, a subscriber station, a mobile unit, a subscriber unit, a wireless unit, a remote unit, a mobile device, a wireless device, a wireless communications device, a remote device, a mobile subscriber station, an access terminal, a mobile terminal, a wireless terminal, a remote terminal, a handset, a user agent, a mobile client, a client, or some other suitable terminology.
  • the UE 206 may communicate with the eNB 204 over a LTE link and a mmW link (when the eNB 204 is capable of mmW system communication), or communicate with the CP/BS 212 over a mmW link and a LTE link (when the CP/BS 212 is capable of LTE network communication).
  • the eNB 204 communicates signals via the LTE network and the mmW system, while the CP/BS 212 communicates signals via the mmW system only. Accordingly, the CP/BS 212 unable to signal the eNB 204 via the LTE network may communicate with the eNB 204 over a mmW backhaul link.
  • the UE 502 may listen for beamformed discovery signals in different receive directions (e.g., directions E, F, G, and H).
  • the UE 502 may sweep through the receive directions according to a sequence E-F-G-H.
  • the UE 502 may sweep through the receive directions according to the sequence F-H-E-J.
  • the CP may schedule communication with the two UEs together in the same timeslot (e.g., FDMA scheduling) for the downlink operation. If x is a fraction of power assigned to the first UE and y is a fraction of bandwidth assigned to the first UE, then a total data rate for FDMA scheduling may be provided by Equation (4) below:
