Abstract

A first node receives a first signaling; transmits a first signal in a first transmission occasion in a first cell group; transmits or drops transmitting a second sub-signal in a second transmission occasion in a second serving cell. The first signaling is used to determine a first time-domain resource; transmit power of the first signal is equal to a first power value; transmit power of a second signal is equal to a second power value, and the second signal comprises the second sub-signal; whether a sum of the first power value and the second power value minus a first maximum transmit power is greater than a first threshold is used to determine whether the second sub-signal is transmitted in the second transmission occasion in the second serving cell. The above method satisfies the demands of different duplex modes for uplink transmit power.
