Claim of US Patent No. 10,396,879

1. A method in a User Equipment (UE) for wireless communication, comprising:transmitting first information;
wherein the first information comprises at least the former two of {K first-type indexes, K1 first-type indexes, K first-type numerical values}, and the K1 first-type indexes are a subset of the K first-type indexes; the K first-type indexes are used for determining K antenna port groups respectively, and one antenna port group comprises a positive integer number of antenna ports; the UE can receive simultaneously radio signals coming from K1 antenna port groups, the K1 antenna port groups are a subset of the K antenna port groups, and the K1 first-type indexes are used for determining the K1 antenna port groups respectively; the K first-type numerical values are used for determining K channel qualities respectively, and the K channel qualities are one-to-one corresponding to the K antenna port groups; the K1 first-type indexes comprise at least one given first-type index, and a position of the given first-type index in the K first-type indexes is used for determining whether an antenna port group corresponding to the given first-type index belongs to the K1 antenna port groups; and the K is a positive integer greater than 1, and the K1 is a positive integer greater than 1 but not greater than the K.
