Abstract: A technique for storing softbits of messages received according to a Hybrid Automatic Repeat Request (HARQ) protocol is disclosed. As to a method aspect of the technique, a first storage (102) and a second storage (104) are provided. The first storage and a second storage include a plurality of memory segments (103) allocatable to HARQ processes. A first message related to a first HARQ process is received. The first message is protected by a channel code of the HARQ protocol and represented by softbits. The softbits of the first message are stored in a first segment of the first storage. The first segment is allocated to the first HARQ process. The first storage is accessible by a channel decoding unit (110) for decoding the channel code. If a number of allocated segments in the first storage, the decoding of which has not been yet completed, exceeds a threshold, the allocation for the first HARQ process is changed from the first segment in the first storage to a second segment in the second storage.

Abstract: The invention relates to a peristaltic pump (1) comprising a saddle and a rotor (3) rotatable therein, between which a hose (4) is arranged. The rotor (3) carries hose compression means (6), which sweep over the hose (4) with the rotation of the rotor (3) and thus convey a conveying fluid. When the hose compression means (6) emerge from the hose (4), this results in pulsation effects. According to the invention, these pulsation effects are suppressed in that an inner saddle face (5), on which the hose (4) is positioned, is suitably shaped. In addition, the pulsation effects may be reduced or prevented by controlled adaptation of the rotor rotational speed, by suitable selection of a conveying end position during metering of the pumping medium, or by establishing particular invariable conveying end positions. The use of a peristaltic pump (1) of this type for metering is further proposed.
