Claim 0:
1. A method for transmitting an uplink signal on physical control channel, the method comprising:
determining that a terminal device has a capability of transmitting the uplink signal on physical control channel in at least a first time instant and a second time instant coherently;
performing a first transmission of the uplink signal on physical control channel in the first time instant in a first set of subcarriers; and
performing a second transmission of the uplink signal on physical control channel in the second time instant in a second set of subcarriers; wherein the capability of transmitting the uplink signal on physical control channel in at least the first time instant and the second time instant coherently is determined based on at least one of the following:
whether the first time instant and the second time instant are consecutive;
a change in transmission power between the first time instant and the second time instant:
a frequency offset between a central frequency of the first set of subcarriers and a central frequency of the second set of subcarriers; and
an uplink spatial relation between uplink control channel transmissions in the first time instant and the second time instant.
