Method and device in communication node used for wireless communication with multiple antenna panels

A second node for wireless communication, comprising:

• a second transmitter, to transmit a first signaling, the first signaling being used for indicating a first time-frequency resource group and the first time-frequency resource group being reserved for a first bit block, and to transmit a second signaling, the second signaling being used for determining a second time-frequency resource group and the second time-frequency resource group being reserved for a second bit block;
• and
• a second receiver, to receive the first bit block in time-frequency resources in the first time-frequency resource group other than a first resource subgroup, and to receive the second bit block in the second time-frequency resource group;
• wherein the first time-frequency resource group and the second time-frequency resource group are partially overlapping, and the first time-frequency resource group comprises the first resource subgroup;
• time-frequency resources in the first time-frequency resource group other than the first resource subgroup are orthogonal to time-frequency resources occupied by the second time-frequency resource group;
• the first signaling is used for determining a first index group, and the second signaling is used for determining a second index group;
• the first index group belongs to one of K index sets, the second index group belongs to one of K index sets, and any two of the K index sets are different;
• whether the first index group and the second index group belong to one same index set among the K index sets is used for determining the first resource subgroup;
• the first index group comprises a positive integer number of index(es), the second index group comprises a positive integer number of index(es), any one of the K index sets comprises a positive integer number of index(es), and K is a positive integer greater than 1.
