Method and device in communication node used for wireless communication

A first-type communication node for wireless communications, comprising:

• a first receiver, receiving first information;
• a second receiver, receiving a first signaling in X time windows;
• and
• a first transmitter, transmitting a first radio signal;
• wherein the first information is used to determine the X time windows, time-domain resources occupied by the first signaling are first time-domain resources, the X being a positive integer greater than 1;
• a start time for a transmission of the first radio signal is related to a first transmission timing adjustment and a second transmission timing adjustment;
• the first signaling is used to determine the first transmission timing adjustment, and the second transmission timing adjustment is related to a position of the first time-domain resources in the X time windows;
• the first information, the first signaling and the first radio signal are all transmitted through an air interface;
• the first signaling is transmitted through a PDCCH with Cyclic Redundancy Check (CRC) scrambled by a RA-RNTI, the first signaling comprises all or part of Fields of DCI.

A second-type communication node for wireless communications, comprising:

• a second transmitter, transmitting first information;
• a third transmitter, transmitting a first signaling in X time windows;
• and
• a third receiver, receiving a first radio signal;
• wherein the first information is used to determine the X time windows, time-domain resources occupied by the first signaling are first time-domain resources, the X being a positive integer greater than 1;
• a start time for a transmission of the first radio signal is related to a first transmission timing adjustment and a second transmission timing adjustment;
• the first signaling is used to determine the first transmission timing adjustment, and the second transmission timing adjustment is related to a position of the first time-domain resources in the X time windows;
• the first information, the first signaling and the first radio signal are all transmitted through an air interface;
• the first signaling is transmitted through a PDCCH with Cyclic Redundancy Check (CRC) scrambled by a RA-RNTI, the first signaling comprises all or part of Fields of DCI.
