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 () and a second storage () are provided. The first storage and a second storage include a plurality of memory segments () 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 () 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.

Technique for storing softbits

According to one aspect of the teachings herein, a wireless device operating in a wireless communication network determines the difference in signal arrival times with respect to first and second cells, and the device and/or the involved wireless communication network uses the difference to control one or more aspects of Carrier Aggregation, CA, operation for the wireless device. For example, there may be a maximum timing difference defined for the wireless device, e.g., as a function of its inherent capabilities, and the wireless device may evaluate the timing difference of a second cell that is a candidate of aggregation into its CA configuration, or that may be a candidate for activation as a serving cell within a CA configuration, with respect to a first cell that is already in use as a serving cell for the wireless device.

A technique for selecting a set of radio resources of a cellular telecommunications network for radio resource aggregation in a communication between the telecommunications network and a User Equipment (UE) is provided. As to a method aspect of the technique, a time offset relative to a primary radio resource for each of at least two secondary radio resources is monitored. The primary radio resource and the at least two secondary radio resources are provided by the telecommunications network for radio resource aggregation. Out of the at least two secondary radio resources, a set of radio resources is selected so that the time offsets monitored for the selected secondary radio resources fall within a time window having a width equal to or less than the threshold, if a spread of the monitored time offsets exceeds a threshold.
