Terminal and communication method
A terminal is disclosed including a reception section that receives second control information from a base station in a Physical Downlink Control Channel (PDCCH) configured for a cell in a specific Physical Uplink Control Channel (PUCCH) group, the second control information indicating a channel for transmitting first control information and data to another terminal in inter-terminal communication; and a transmission section that transmits a second response signal to the base station with a PUCCH configured for a specific cell in the specific PUCCH group, the second response signal being based on a first response signal transmitted by the other terminal having received the data. In other aspects, a communication system and a communication method are also disclosed.
1 . A terminal, comprising:
a reception section that receives second control information from a base station in a Physical Downlink Control Channel (PDCCH) related to a sidelink (SL) configured for a cell in a specific Physical Uplink Control Channel (PUCCH) group, the second control information indicating a channel for transmitting first control information and data to another terminal in inter-terminal communication; and
a transmission section that transmits a second response signal to the base station with a PUCCH configured for a specific cell in the specific PUCCH group, the second response signal being based on a first response signal transmitted by the other terminal having received the data, wherein:
the reception section receives a first higher layer parameter and a second higher layer parameter that are related to the SL, the first higher layer parameter including first configuration information, the second higher layer parameter including the second configuration information,
the first configuration information indicates a resource in which the PDCCH is configured, and
the second configuration information indicates a resource in which the PUCCH is configured.
2 . The terminal according to claim 1 , wherein the specific cell in the specific PUCCH group is a PUCCH-Secondary Cell (SCell).
3 . A communication system, comprising:
a base station;
a first terminal that communicates with the base station; and
a second terminal that performs inter-terminal communication with the first terminal,
wherein the first terminal includes:
a reception section that receives second control information from the base station in a Physical Downlink Control Channel (PDCCH) related to a sidelink (SL) configured for a cell in a specific Physical Uplink Control Channel (PUCCH) group, the second control information indicating a channel for transmitting first control information and data to the second terminal; and
a transmission section that transmits a second response signal to the base station with a PUCCH configured for a specific cell in the specific PUCCH group, the second response signal being based on a first response signal transmitted by the second terminal having received the data, wherein:
the reception section receives a first higher layer parameter and a second higher layer parameter that are related to the SL, the first higher layer parameter including first configuration information, the second higher layer parameter including the second configuration information,
the first configuration information indicates a resource in which the PDCCH is configured, and
the second configuration information indicates a resource in which the PUCCH is configured.
4 . A communication method performed by a terminal, the communication method comprising:
receiving second control information from a base station in a Physical Downlink Control Channel (PDCCH) related to a sidelink (SL) configured for a cell in a specific Physical Uplink Control Channel (PUCCH) group, the second control information indicating a channel for transmitting first control information and data to another terminal in inter-terminal communication;
transmitting a second response signal to the base station with a PUCCH configured for a specific cell in the specific PUCCH group, the second response signal being based on a first response signal transmitted by the other terminal having received the data; and
receiving a first higher layer parameter and a second higher layer parameter that are related to the SL, the first higher layer parameter including first configuration information, the second higher layer parameter including the second configuration information,
wherein the first configuration information indicates a resource in which the PDCCH is configured, and
wherein the second configuration information indicates a resource in which the PUCCH is configured.
