A heating device infrared radiation lamps 24, 26 designed to perform rapid thermal processing of the substrate 12 inside a reaction chamber 14 with a transparent window 34. Laser shock processing is used to provide the shockwaves. The scheduler is configured to generate the scheduling information such that downlink data channels and downlink control channels are transmitted using the transmission time interval as a transmission unit and uplink control channels are transmitted using an integral multiple of the transmission time interval as a transmission unit. Each microlens has a focal point and each microlens is associated with a corresponding block of display pixels. For a 1-bit ACK, the scrambling is performed to achieve any two corners in any constellation for transmission for the ACK.
