Abstract
The present invention implements appropriate retransmission control processing in accordance with a radio propagation environment. This terminal is provided with a reception circuit for receiving control information relating to buffering for retransmission control, and a control circuit for controlling buffering on the basis of the control information.
Claims14
A terminal, comprising:
- reception circuitry, which, in operation, receives control information on buffering for retransmission control;
- and
- control circuitry, which, in operation, controls the buffering based on the control information, the control information including information indicating a priority of the buffering between a plurality of data, wherein,
- the control circuitry, in operation, controls saving and discarding of data of the plurality of data in a buffer based on the information indicating the priority, wherein,
- when there is no free space in the buffer, the control circuitry, in operation, overwrites, with received data, data in the buffer having a lower priority than the received data, and
- when there is no data having the lower priority in the buffer, the control circuitry, in operation, discards the received data.
3 more elements
A base station, comprising:
- control circuitry, which, in operation, generates control information on buffering for retransmission control;
- and
- transmission circuitry, which, in operation, transmits the control information, the control information including information indicating a priority of the buffering between a plurality of data, wherein saving and discarding of data of the plurality of data in a buffer is controlled based on the information indicating the priority, wherein,
- when there is no free space in the buffer, the saving and discarding of data is controlled to overwrite, with received data, data in the buffer having a lower priority than the received data, and
- when there is no data having the lower priority in the buffer, the saving and discarding of data is controlled to discard the received data.
2 more elements
A receiving method, comprising the following performed by a terminal:
- receiving control information on buffering for retransmission control;
- and
- controlling the buffering based on the control information, the control information including information indicating a priority of the buffering between a plurality of data, wherein saving and discarding of data of the plurality of data in a buffer is controlled based on the information indicating the priority, wherein,
- when there is no free space in the buffer, the saving and discarding of data is controlled to overwrite, with received data, data in the buffer having a lower priority than the received data, and
- when there is no data having the lower priority in the buffer, the saving and discarding of data is controlled to discard the received data.
2 more elements
A transmitting method comprising the following performed by a base station:
- generating control information on buffering for retransmission control;
- and
- transmitting the control information, the control information including information indicating a priority of the buffering between a plurality of data, wherein saving and discarding of data of the plurality of data in a buffer is controlled based on the information indicating the priority, wherein,
- when there is no free space in the buffer, the saving and discarding of data is controlled to overwrite, with received data, data in the buffer having a lower priority than the received data, and
- when there is no data having the lower priority in the buffer, the saving and discarding of data is controlled to discard the received data.
