Method and device in UE and base station used for wireless communication
View Patent ↗A method and a device in a User Equipment and a base station used for wireless communication. The UE receives a target radio signal and transmits first information on a target channel in turn. A channel measurement for the target radio signal is used for triggering the transmission of the first information. The target channel is a first type of physical layer channel or a second type of physical layer channel. If the target channel is the first type of physical layer channel, the transmission of the first information on the target channel is counted into the number of transmission times of the first information. Otherwise, the number of transmission times of the first information is unrelated to the transmission of the first information on the target channel. The present disclosure improves the success rate of retransmission, supports flexible configuration, and saves the transmit power consumption of the UE.
