Method and device for use in user device and base station used for wireless communication

A base station for wireless communications, comprising:

• a second transmitter, transmitting first information, the first information being used to determine a first time-frequency resource and a first parameter group;
• transmitting a first signaling, the first signaling being used to determine a second time-frequency resource and a second parameter group;
• and
• a second transceiver, transmitting a first radio signal in the first time-frequency resource, and transmitting a second radio signal in the second time-frequency resource;
• wherein the first signaling is a DCI signaling, a start time for transmitting the first signaling is later than a start time for transmitting the first information;
• the second parameter group is used to generate the second radio signal, a target parameter group is used to generate the first radio signal, and the target parameter group is the first parameter group or the second parameter group;
• the first parameter group comprises a TCI, and the second parameter group comprises a TCI;
• a first condition set is used to determine the target parameter group out of the first parameter group and the second parameter group;
• the first condition set comprises N conditions, N being a positive integer greater than 1;
• a target time-domain resource set comprises time-domain resources occupied by the first time-frequency resource, and
• one of the N conditions comprises that a reference time-domain resource is non-orthogonal to the target time-domain resource set, wherein the reference time-domain resource comprises time-domain resources occupied by the second time-frequency resource;
• one of the N conditions comprises that a time gap between the first signaling and the second radio signal belongs to a first gap set.
