Method of dynamic allocation of shared resources in a time-frequency plan and associated device

摘要

A method is provided of dynamic allocation of shared resources in a communication network, consisting in defining, in a time-frequency plan, a superframe of a given duration ΔT and a given spectral width Δf, made up of one or more frames, each defining a regular time-frequency grid, of which one square, referred to as a time-frequency unit, constitutes the smallest time and frequency interval allocable to a user of said network within said frame, said method consisting in reserving, on each carrier frequency of a frame, at least one block of a number K, greater than or equal to 1, of time-frequency units which can be dynamically allocated to a user for communication or for synchronization.

1. A computer-implemented method of dynamic allocation of shared resources in a communication network including a plurality of receivers, the computer-implemented method being executed by a resource allocation device, the method comprising:
defining, at a resource allocation device, in a time-frequency plan, a superframe of a given duration ΔT and a given spectral width Δf, including at least one frame, defining, at the resource allocation device, a regular time-frequency grid, of which one square, referred to as a time-frequency unit, constitutes the smallest time and frequency interval allocatable to a user at the at least one receiver of said communication network within said frame, and reserving, at the resource allocation device, on each carrier frequency of a frame, at least one block of a number K, greater than or equal to 1, of time-frequency units which can be dynamically allocated to a user for communication or for synchronization, wherein the number of time-frequency units per frame allocated for synchronization is at least equal to the minimum number Nu of time-frequency units per frame required to provide the synchronization of all connected users, this minimum number Nu being equal to the rounded value of the ratio of the duration of a superframe to the synchronization period of the user, multiplied by the number of users connected to the communication network, and transmitting, by the resource allocation device, to at least a receiver an information regarding the allocation of at least one time-frequency unit for communication and at least one time-frequency unit for synchronization to the receiver.
