Terminal and transmission method
This terminal is provided with: a circuit that, on the basis of information relating to the number of symbols usable in some time interval, determines disposition of one or more channels in the time interval; and a transmitter that transmits the channel in accordance with the disposition.
1 . A terminal, comprising:
circuitry, which, in operation, maps a physical sidelink shared channel (PSSCH) and a physical sidelink feedback channel (PSFCH) in a slot in a first case where there is a first number of symbols available for sidelink transmission starting at a first symbol of the slot, and maps one of the PSSCH or the PSFCH in the slot in a second case where there is a second number of symbols available for sidelink transmission starting at a second symbol of the slot, the second symbol being later than the first symbol; and
a transmitter, which, in operation, transmits the PSSCH and the PSFCH in the slot in the first case and transmits the PSSCH or the PSFCH in the slot in the second case.
2 . The terminal according to claim 1 , wherein information on the first number of symbols and the second number of symbols is indicated by a higher layer signaling.
3 . The terminal according to claim 1 , wherein the first number of symbols is larger than the second number of symbols.
4 . The terminal according to claim 1 , wherein the PSSCH is mapped without the PSFCH in the second case where there is the second number of symbols available in the slot.
5 . The terminal according to claim 1 , wherein the PSFCH is mapped without the PSSCH in the second case where there is the second number of symbols available in the slot.
6 . The terminal according to claim 1 , wherein a transmission cycle of the PSFCH is N slots, and the PSFCH is transmitted without the PSSCH in the second case where there is the second number of symbols available in the slot and where there is the PSFCH in the slot.
7 . A communication method, comprising:
mapping a physical sidelink shared channel (PSSCH) and a physical sidelink feedback channel (PSFCH) in a first case where there is a first number of symbols available for sidelink transmission starting at a first symbol of a slot, and mapping one of the PSSCH or the PSFCH in a second case where there is a second number of symbols available for sidelink transmission starting at a second symbol of the slot, the second symbol being later than the first symbol; and
transmitting the PSSCH or the PSFCH.
8 . The communication method according to claim 7 , wherein information on the first number of symbols and the second number of symbols is indicated by a higher layer signaling.
9 . The communication method according to claim 7 , wherein the first number of symbols is larger than the second number of symbols.
10 . The communication method according to claim 7 , wherein the PSSCH is mapped without the PSFCH in the second case where there is the second number of symbols available in the slot.
11 . The communication method according to claim 7 , wherein the PSFCH is mapped without the PSSCH in the second case where there is the second number of symbols available in the slot.
12 . The communication method according to claim 7 , wherein a transmission cycle of the PSFCH is N slots, and the PSFCH is transmitted without the PSSCH in the second case where there is the second number of symbols available in the slot and where there is the PSFCH in the slot.
