Communication device and communication method
A communication device includes a receiving unit that receives information indicating a time division duplex (TDD) configuration; a control unit that obtains information related to an uplink, in the received information indicating the TDD configuration; and a transmitting unit that transmits the information related to the uplink on a sidelink.
1. A terminal comprising:
a receiving unit that receives, from a base station, configuration information indicating a time division duplex (TDD) configuration;
a control unit that obtains first information indicating a value related to a period in an inter-terminal communication based on a pattern of the TDD configuration included in the configuration information, and obtains second information indicating a value related to a number of slots usable for the inter-terminal communication based on the pattern and a subcarrier spacing; and
a transmitting unit that transmits the first information and the second information to another terminal.
2. The terminal according to claim 1 , wherein the transmitting unit transmits the first information and the second information by using a broadcast channel for the inter-terminal communication.
3. A communication system comprising:
a base station including:
a transmitting unit that transmits, to a terminal, configuration information indicating a time division duplex (TDD) configuration; and
the terminal including:
a receiving unit that receives the configuration information from the base station;
a control unit that obtains first information indicating a value related to a period in an inter-terminal communication based on a pattern of the TDD configuration included in the configuration information, and obtains second information indicating a value related to a number of slots usable for the inter-terminal communication based on the pattern and a subcarrier spacing; and
a transmitting unit that transmits the first information and the second information to another terminal.
4. A communication method executed by a terminal, the method comprising:
receiving, from a base station, configuration information indicating a time division duplex (TDD) configuration;
obtaining first information indicating a value related to a period in an inter-terminal communication based on a pattern of the TDD configuration included in the configuration information, and obtaining second information indicating a value related to a number of slots usable for the inter-terminal communication based on the pattern and a subcarrier spacing; and
transmitting the first information and the second information to another terminal.
