Disclosed is a dual-stator superconductive exciting field modulating machine, which comprises a first stator (1), a rotor (3) and a second stator (5) which are provided successively from outside to inside or from the left to the right, wherein a first air gap (2) is provided between the first stator and the rotor, and a second air gap (4) is provided between the second stator and the rotor; the first stator comprises a stator yoke (11) and an armature winding, the stator yoke being provided with a first side face close to the rotor, and the armature winding being arranged on the first side face; the rotor comprises magnetic conductive iron core blocks (31) and non-magnetic conductive blocks (32) which are arranged at intervals; and the second stator comprises a non-magnetic conductive stator support (51) and a high-temperature superconductive exciting winding (52) fixed on the stator support. The dual-stator superconductive exciting field modulating machine is small in size, is light in weight, is high in efficiency, and not only utilizes a characteristic of a high-temperature superconductive winding being suitable for the direct current, but also prevents the problem of the rotating seal of cooling liquid required by a traditional rotor exciting high-temperature superconducting machine.

Disclosed in some examples is a method for providing a HARQ response in an LTE network for a PUCCH format 1b. The method includes receiving one or more downlink assignments of a bundling window over a wireless downlink control channel; setting a reception status for each sub-frame of a downlink data channel in the bundling window based on whether the sub-frame on the downlink data channel was associated with a particular one of the received downlink assignments and based upon whether the sub-frame was successfully received; setting a reception status of sub-frames of the downlink data channel in the bundling window that did not have a corresponding downlink assignment to a predetermined value; and transmitting a response, the response based upon the reception statuses set by the response module.
