Terminal, radio communication method, and base station
A terminal according to an aspect of the present disclosure includes: a receiving section that receives information related to schedule; a transmitting section that transmits, to another terminal, information related to part of UL data, the part of the UL data being obtained by dividing the UL data in at least one of a unit of transport block, a unit of codeword, a unit of code block, and a unit of bit; and a control section that performs control to transmit the UL data in cooperation with the another terminal, based on the information related to the schedule.
1 . A terminal comprising:
a receiving section that receives information related to schedule of uplink (UL) data;
a transmitting section that transmits, to another terminal, the UL data and information related to part of the UL data, the part of the UL data being obtained by dividing the UL data in at least one of a unit of transport block, a unit of codeword and a unit of bit; and
a control section that performs control to transmit the UL data scheduled by the information related to the schedule in cooperation with the another terminal, by transmitting to the base station the UL data not transmitted from the another terminal,
wherein the information related to the part of the UL data includes control information and channel state information related to the UL data, and
wherein a first demodulation reference signal corresponding to first UL data transmitted by the terminal and a second demodulation reference signal corresponding to second UL data transmitted by the another terminal are configured at least one parameter in common.
2 . The terminal according to claim 1 , wherein
the transmitting section transmits the part of the UL data and the information related to the part of the UL data to the another terminal by using a higher layer.
3 . The terminal according to claim 1 , wherein
the transmitting section transmits the part of the UL data and the information related to the part of the UL data to the another terminal by using a channel used for device-to-device communication and a channel for sidelink.
4 . The terminal according to claim 3 , wherein
the transmitting section transmits the part of the UL data and the information related to the part of the UL data by using any resource included in a resource pool or a scheduled resource.
5 . A radio communication method of a terminal, the radio communication method comprising:
receiving information related to schedule of uplink (UL) data;
transmitting, to another terminal, the UL data and information related to part of the UL data, the part of the UL data being obtained by dividing the UL data in at least one of a unit of transport block, a unit of codeword and a unit of bit; and
performing control to transmit the UL data scheduled by the information related to the schedule in cooperation with the another terminal, by transmitting to the base station the UL data not transmitted from the another terminal,
wherein the information related to the part of the UL data includes control information and channel state information related to the UL data, and
wherein a first demodulation reference signal corresponding to first UL data transmitted by the terminal and a second demodulation reference signal corresponding to second UL data transmitted by the another terminal are configured at least one parameter in common.
6 . A base station comprising:
a transmitting section that transmits information related to schedule of uplink (UL) data to a first terminal;
a control section that configures a resource or a resource pool to be used for transmission of the UL data and information related to part of the UL data, the part of the UL data being obtained by dividing the UL data in at least one of a unit of transport block, a unit of codeword and a unit of bit; and
a receiving section that receives the UL data, scheduled by the information related to the schedule, cooperatively transmitted from the first terminal and a second terminal, by reception from the first terminal the UL data not transmitted from the second terminal,
wherein the information related to the part of the UL data includes control information and channel state information related to the UL data, and
wherein a first demodulation reference signal corresponding to first UL data transmitted by the first terminal and a second demodulation reference signal corresponding to second UL data transmitted by the second terminal are configured at least one parameter in common.
