  • Persistent Allocation is a scheduling method that efficiently allocates resources for connections with periodic traffic patterns and relatively fixed payload sizes.
  • the base station allocates resources without a control signal (eg, A-MAP) when the resources are periodically allocated to the terminal with the corresponding connection after the initial allocation, and the terminal initially allocates the resources through persistent allocation. If received, it is determined that resources are periodically allocated through the resource allocation information received initially, and exchanges traffic with the base station using the allocated resource region.
