Claim 15:
16. A base station in wireless transmission, comprising:
a second transmitter, to transmit a first signaling;
a third transmitter, to transmit a first radio signal, the first radio signal carrying a first bit block; and
a third receiver, to receive a third signaling;
wherein the first signaling is a physical layer signaling, the first signaling is a Downlink control information (DCI), the first signaling includes scheduling information of the first radio signal, and the scheduling information includes at least one of occupied time-frequency resources, an Modulation and coding scheme (MCS), an Redundancy Version (RV), or a Hybrid Automatic Repeat request (HARQ) Process Number; the first signaling is used for determining a transmission format corresponding to the first radio signal, the first bit block is a Transport Block (TB), and the first bit block comprises a positive integer number of bits; the transmission format corresponding to the first radio signal is one transmission format in a first format set, and the first format set comprises a first transmission format and a second transmission format; a radio signal corresponding to the first transmission format comprises P radio sub-signal(s), each of the P radio sub-signal(s) carries the first bit block, each of the P radio sub-signal(s) is transmitted by a same antenna port group, and the P is a positive integer; the P is equal to 1, or, the P is greater than 1 and time domain resources occupied by any two of the P radio sub-signals are orthogonal; a radio signal corresponding to the second transmission format comprises Q radio sub-signals, each of the Q radio sub-signals carries the first bit block, the Q radio sub-signals are transmitted by Q antenna port groups respectively, any two of the Q antenna port groups cannot be assumed to be same, time domain resources occupied by any two of the Q radio sub-signals are orthogonal, and the Q is an integer greater than 1; and the antenna port group comprises one or more antenna ports; the third signaling is used for indicating whether the first radio signal is correctly received; and a physical layer channel corresponding to the first radio signal includes a PDSCH.
