Abstract
A method and a system for the fractional reuse of frequencies in a wireless network. The method includes the following steps: obtaining at least one PHY based index defining a preferred allocation of a mobile station among at least two frequency reuse zones in a cell of said communication network; and scheduling bursts of packets to transmit to the mobile station, by at least one frequency reuse zone among the at least two frequency reuse zones, in view of transmission requests and the at least one PHY based index.
Claims10
A dynamic packet scheduling method in a cellular Orthogonal Frequency-Division Multiple Access—Time-Division Duplexing (OFDMA-TDD) network, wherein said dynamic packet scheduling method comprises the following steps:
- obtaining at least one physical layer (PHY) based index defining a preferred allocation of a mobile station among at least two frequency reuse zones in a cell of said (OFDMA-TDD) network;
- scheduling bursts of packets to transmit to said mobile station, by at least one frequency reuse zone among the at least two frequency reuse zones, in view of transmission requests and said at least one PHY based index;
- and
- transmitting the bursts of packets based on the scheduling.
A dynamic packet scheduling apparatus in a cellular Orthogonal Frequency-Division Multiple Access—Time-Division Duplexing (OFDMA-TDD) network wherein the apparatus comprises:
- a processor for:
- obtaining at least one physical layer (PHY) based index defining a preferred allocation of a mobile station among at least two frequency reuse zones in a cell of said (OFDMA-TDD) network;
- scheduling bursts of packets to transmit to said mobile station, by at least one frequency reuse zone among the at least two frequency reuse zones, in view of transmission requests and said at least one PHY based index;
- and
- transmitting the bursts of packets based on the scheduling.
A computer program product stored on a non-transitory computer-readable medium and executable by a microprocessor, said computer program product comprising program code instructions for:
- obtaining at least one physical layer (PHY) based index defining a preferred allocation of a mobile station among at least two frequency reuse zones in a cell of a cellular Orthogonal Frequency-Division Multiple Access—Time-Division Duplexing (OFDMA-TDD) network;
- scheduling bursts of packets to transmit to said mobile station, by at least one frequency reuse zone among the at least two frequency reuse zones, in view of transmission requests and said at least one PHY based index;
- transmitting the bursts of packets based on the scheduling.
