Claim 15:
16. A method in a base station for wireless communication, comprising:
transmitting a first signaling, the first signaling being used for determining a first time-frequency resource group, and the first time-frequency resource group being reserved for transmission of a first bit block;
transmitting a first radio signal; and receiving K radio signals and the first bit block in K time-frequency resource groups; wherein time-domain resources occupied by the first time-frequency resource group are overlapping with time-domain resources occupied by at least one of the K time-frequency resource groups, and any two of the K time-frequency resource groups are orthogonal in time domain; the K radio signals are transmitted in the K time-frequency resource groups respectively, and the first bit block is transmitted in only K1 time-frequency resource group(s) among the K time-frequency resource groups; the first signaling corresponds to a first type or a second type, and whether the first signaling corresponds to the first type or the second type is used for determining the K1 time-frequency resource group(s) from the K time-frequency resource groups; the K is a positive integer greater than 1, and the K1 is a positive integer not greater than the K;
the first signaling is a Downlink Control Information (DCI) signaling; the K time-frequency resource groups all include time-frequency resources belonging to a PUSCH; the first radio signal includes a CSI-RS (Channel State Information-Reference Signal), and the first bit block is used for indicating a CSI (Channel State Information) obtained based on a measurement of the first radio signal;
when the first signaling corresponds to the first type, the K1time-frequency resource group(s) is (are) K1 earliest time-frequency resource group(s) in time domain among K2 time-frequency resource group(s) respectively; each of the K2 time-frequency resource group(s) is one of the K time-frequency resource groups, and K2 is a positive integer not less than the K1 but not greater than the K; the K2 is equal to the K and the K2 time-frequency resource groups are the K time-frequency resource groups respectively; or, the K2 time-frequency resource group(s) is (are) all time-frequency resource groups overlapping with the first time-frequency resource group in time domain among the K time-frequency resource groups;
when the first signaling corresponds to the second type, the K1 time-frequency resource group(s) is (are) K1 latest time-frequency resource group(s) in time domain among K3 time-frequency resource group(s) respectively; each of the K3 time-frequency resource group(s) is one of the K time-frequency resource groups, and the K3 is a positive integer not less than the K1 but not greater than the K; the K3 is equal to the K and the K3 time-frequency resource groups are the K time-frequency resource groups respectively; or, the K3 time-frequency resource group(s) is (are) all time-frequency resource groups overlapping with the first time-frequency resource group in time domain among the K time-frequency resource groups; the K1 is equal to 1, or the K1 is greater than 1, or the K1 is predefined, or the K1 is configurable, or a number of bits comprised in the first bit block is used for determining the KI.
