Abstract
A radio terminal according to an embodiment is configured to perform direct communication with another radio terminal. The radio terminal comprises a controller configured to receive first data addressed to said another radio terminal from a base station. When the controller receives the first data from the base station, the controller is configured to also receive information indicating a first radio resource used for transferring the first data to said another radio terminal by the direct communication.

A radio terminal configured to perform direct communication with another radio terminal, the radio terminal comprising:
- a controller configured to
- receive first data addressed to said another radio terminal from a base station,
- receive, along with the first data, first information indicating a first radio resource, and
- transmit the first data to said another radio terminal by using the first radio resource, through the direct communication, wherein
- the controller is configured to receive, from the base station, second information indicating a second radio resource configured to be used for transmitting second data addressed to said another radio terminal,
- the second data is configured to be generated in the radio terminal,
- the first information is configured to be transmitted by the base station at a timing when a first period configured by the base station is to be longer than a second period configured by the base station,
- the first period is a period from a time of receiving, by the radio terminal, the first information to a time of starting transmission of the first data by the radio terminal, and
- the second period is a period from a time of receiving, by the radio terminal, the second information to a time of starting transmission of the second data by the radio terminal.
A base station comprising:
- a controller configured to
- transmit first data to a first radio terminal, the first data being addressed to a second radio terminal capable of performing direct communication with the first radio terminal, and
- transmits, along with the data, first information on a first radio resource by which the first radio terminal transmits the first data to the second radio terminal through the direct communication, wherein
- the controller is configured to transmit, to the first radio terminal, second information indicating a second radio resource configured to be used by the first radio terminal for transmitting second data addressed to the second radio terminal,
- the second data is configured to be generated in the first radio terminal,
- the first information is configured to be transmitted by the base station at a timing when a first period configured by the base station is to be longer than a second period configured by the base station,
- the first period is a period from a time of receiving, by the first radio terminal, the first information to a time of starting transmission of the first data by the first radio terminal, and
- the second period is a period from a time of receiving, by the second radio terminal, the second information to a time of starting transmission of the second data by the first radio terminal.
