Abstract

Communication equipment allocates a communication resource region which is used for communication with equipment of a communicating party and performs scheduling of resources. A data classification unit classifies data into small-volume RTD, large-volume RTD or nRTD. Based on the result of the classification, a scheduling unit allocates a communication resource region under a first condition that the RTD has priority over the nRTD, a second condition that the small-volume RTD has priority over the large-volume RTD, a third condition that a previously used communication resource region is, if possible, allocated to the small-volume RTD, and a fourth condition that the large-volume RTD and nRTD are allocated with priority given to equipment of a communicating party for which high communication quality is ensured. A communication unit performs communication with the equipment of the communicating party according to the result of the scheduling.

Claims

1. Communication equipment for allocating a communication resource region which is used for communication with equipment of a communicating party, comprising:

a data distribution system that classifies data, which is an object of communication in communication with the equipment of the communicating party, into small-volume real-time data (RTD), large-volume RTD, and non-real-time data (nRTD) and distributes the data;

a first scheduler that based on a result of the distribution by the data distribution system allocates the communication resource region to the small-volume RTD, the first scheduler allocating to the small-volume RTD the communication resource region which has not been allocated to any other small-volume RTD and over which the highest communication quality is ensured, when allocating the communication resource region to the equipment of the communicating party for the first time;

a second scheduler that allocates the communication resource region to the large-volume RTD and the nRTD, the second scheduler allocating, after the first scheduler completes the allocation of the communication resource region, the communication resource region to the large-volume RTD with priority over the nRTD; and

a communication system that performs communication with the equipment of the communicating party according to a result of scheduling by the first scheduler and the second scheduler.

2. Communication equipment for allocating a communication resource region which is used when data is transmitted to equipment of a communicating party, comprising:

a downlink data distribution unit that classifies data, which is transmitted to the equipment of the communicating party, into small-volume real-time data (RTD), large-volume RTD, and non-real-time data (nRTD) and distributes the data;

a first scheduler that based on a result of the distribution by the downlink data distribution unit allocates the communication resource region to the small-volume RTD, the first scheduler allocating to the small-volume RTD the communication resource region which has not been allocated to any other small-volume RTD and over which the highest communication quality is ensured, when allocating the communication resource region to the equipment of the communicating party for the first time;

a second scheduler that allocates the communication resource region to the large-volume RTD and the nRTD, the second scheduler allocating, after the first scheduler completes the allocation of the communication resource region, the communication resource region to the large-volume RTD with priority over the nRTD; and

a transmitted signal processing unit that transmits a signal of transmitted data by radio to the equipment of the communicating party according to a result of the scheduling by the first scheduler and the second scheduler.

3. Communication equipment for allocating a communication resource region which is used when data is received from equipment of a communicating party, comprising:

an uplink data distribution unit that classifies a scheduling request, which is received from the equipment of the communicating party, as a scheduling request of small-volume real-time data (RTD), a scheduling request of large-volume RTD, and a scheduling request of non-real-time data (nRTD) and distributes the scheduling request;

a first scheduler that based on a result of the distribution by the uplink data distribution unit allocates the communication resource region to the small-volume RTD, the first scheduler allocating to the small-volume RTD the communication resource region which has not been allocated to any other small-volume RTD and over which the highest communication quality is ensured, when allocating the communication resource region to the equipment of the communicating party for the first time;

a second scheduler that allocates the communication resource region to the large-volume RTD and the nRTD, the second scheduler allocating, after the first scheduler completes the allocation of the communication resource region, the communication resource region to the large-volume RTD with priority over the nRTD; and

a received signal processing unit that processes a baseband signal of a signal which is received from the equipment of the communicating party according to a result of the scheduling by the first scheduler and the second scheduler.
