Terminal, radio communication method, and base station
A terminal according to one aspect of the present disclosure includes a control section that determines a spatial relation for a physical uplink control channel on the basis of a control resource set having a lowest identifier, and a transmitting section that simultaneously transmits the physical uplink control channel on the basis of the spatial relation by using a plurality of coherent panels. According to one aspect of the present disclosure, it is possible to appropriately perform simultaneous UL transmission using multiple panels.
1 . A terminal comprising:
a receiver that receives, by radio resource control (RRC) signaling, a configuration of two transmission configuration indicator (TCI) states; and
a processor that controls, based on the two TCI states, repetitive transmission of a physical uplink control channel (PUCCH) using multiple panels,
wherein when a plurality of control resource set (CORESET) pool indices are configured, a spatial relation of the PUCCH is determined in accordance with the two TCI states corresponding to a CORESET that is associated with each of the configured CORESET pool indices, and
wherein the spatial relation of the PUCCH is same as a spatial relation of a physical downlink control channel (PDCCH) in the CORESET that is associated with each of the configured CORESET pool indices.
2 . The terminal according to claim 1 , wherein the processor controls transmission of the PUCCH in a same time resource and a same frequency resource.
3 . A radio communication method for a terminal, comprising:
receiving, by radio resource control (RRC) signaling, a configuration of two transmission configuration indicator (TCI) states; and
