Abstract
A base transceiver station performing communications with user equipment, includes a receiving unit to receive an uplink transmission signal containing a propagation path fluctuation value between a self-device and the user equipment from the user equipment; and a communication permitting unit to control a period of time during which a permission of communications is given to the user equipment based on the propagation path fluctuation value.
Claims7
A communication control method in a base transceiver station communicating with user equipment, comprising:
- receiving an uplink transmission signal containing a propagation path fluctuation value between the base transceiver station and the user equipment from the user equipment;
- and
- controlling a period of time during which a permission of communications is given to the user equipment based on the propagation path fluctuation value,
- giving no permission of the communications to the user equipment when the propagation path fluctuation value exceeds a second specified value larger than a first specified value and giving no permission of the communications to the user equipment other than the user equipment satisfying a predetermined condition when the propagation path fluctuation value is equal to or smaller than the first specified value, while giving the permission of the communications to the user equipment when the propagation path fluctuation value exceeds the first specified value but is equal to or smaller than the second specified value, and
- giving the permission of the communications to the user equipment that has not been given the permission of the communication for a specified period of time or longer.
A base transceiver station communicating with user equipment, the base transceiver station comprising:
- a receiver to receive an uplink transmission signal containing a propagation path fluctuation value between the base transceiver station and the user equipment from the user equipment;
- and
- a scheduler to control a period of time during which a permission of communications is given to the user equipment based on the propagation path fluctuation value, and
- wherein the scheduler does not give the permission of the communications to the user equipment when the propagation path fluctuation value exceeds a second specified value larger than a first specified value and does not give the permission of the communications to the user equipment other than the user equipment satisfying a predetermined condition when the propagation path fluctuation value is equal to or smaller than the first specified value, while the scheduler gives the permission of the communications to the user equipment when the propagation path fluctuation value exceeds the first specified value but is equal to or smaller than the second specified value, and
- wherein the scheduler gives the permission of the communications to the user equipment that has not been given the permission of the communication for a specified period of time or longer.
A base transceiver station communicating in a way that switches over user equipment as a communication destination by giving a permission of communications to the user equipment, the base transceiver station comprising:
- a receiver to receive, from the user equipment, an uplink transmission signal containing a propagation path fluctuation value between the base transceiver station and user equipment;
- a propagation path fluctuation value calculating unit to calculate the propagation path fluctuation value between the user equipment and the base transceiver station by use of the uplink transmission signal;
- and
- a scheduler to control a period of time during which a permission of communications is given to the user equipment based on the propagation path fluctuation value, and
- wherein the scheduler does not give the permission of the communications to the user equipment when the propagation path fluctuation value exceeds a second specified value larger than a first specified value and does not give the permission of the communications to the user equipment other than the user equipment satisfying a predetermined condition when the propagation path fluctuation value is equal to or smaller than the first specified value, while the scheduler gives the permission of the communications to the user equipment when the propagation path fluctuation value exceeds the first specified value but is equal to or smaller than the second specified value, and
- wherein the scheduler gives the permission of the communications to the user equipment that has not been given the permission of the communication for a specified period of time or longer.
