Communication device and wireless communication method
First Claim
1. A communication device that supports a D2D (Device-to-Device) communication, the communication device comprising:
- a storage configured to store a first resource pool information that indicates first resource pool including control resources allocated to control information for transmitting data and a second resource pool information that indicates second resource pool including data resources allocated to data, the data is a first type or a second type;
a scheduler configured to select a first resource for transmitting control information from the first resource pool and select a second resource for transmitting data from the second resource pool;
a transmitter configured to transmit the control information by using the first resource and transmit the data by using the second resource, anda processor circuit configured to control to perform a carrier sense in a first range when the transmitter transmits data of the first type, and to control to perform a carrier sense in a second range when the transmitter transmits data of the second type, the first range being larger than the second range and the second range being a portion of the first range, whereinthe scheduler selects the second resource from the second resource pool according to a received signal intensity in at least one of resources included in the first resource pool and the second resource pool.

Abstract
A communication device supports a D2D (Device-to-Device) communication and includes a storage, a scheduler and a transmitter. The storage stores a first resource pool information that indicates first resource pool including control resources allocated to control information for transmitting data and a second resource pool information that indicates second resource pool including data resources allocated to data. The scheduler selects a first resource for transmitting control information from the first resource pool and selects a second resource for transmitting data from the second resource pool. The transmitter transmits the control information by using the first resource and transmit the data by using the second resource. The scheduler selects the second resource from the second resource pool according to a received signal intensity in at least one of resources included in the first resource pool and the second resource pool.

14. A communication method in a communication device that supports a D2D (Device-to-Device) communication, the communication method comprising:
-
storing a first resource pool information that indicates first resource pool including control resources allocated to control information for transmitting data and a second resource pool information that indicates second resource pool including data resources allocated to data in a memory, the data is a first type or a second type; selecting a first resource for transmitting control information from the first resource pool and selecting a second resource for transmitting data from the second resource pool according to a received signal intensity in at least one of resources included in the first resource pool and the second resource pool; performing a carrier sense in a first range when the communication device transmits data of the first type; performing a carrier sense in a second range when the communication device transmits data of the second type, the first range being larger than the second range and the second range being a portion of the first range; and transmitting the control information by using the first resource and transmitting the data by using the second resource after the carrier sense.
