Abstract: The solution presented herein discloses a method of transmitting first symbols via a transceiver comprising a receiver and a transmitter. The method comprises determining a timing discrepancy between a previous reference timing and a current reference timing. The current reference timing is established responsive to a reduced sampling rate used to process second symbols received by the receiver, where the reduced sampling rate is less than a minimum sampling rate at which an inter-symbol distance between the second symbols can be represented by an integer number of samples. The method further comprises adjusting the current reference timing responsive to the timing discrepancy to generate an adjusted reference timing, and determining an uplink transmission timing responsive to the adjusted reference timing. The method further comprises transmitting the first symbols via the transmitter according to the determined uplink transmission timing.

Abstract: The solution presented herein discloses a method of reducing inter-symbol jitter caused while processing each of a plurality of OFDM symbols in a received signal. For each of the plurality of OFDM symbols, the method comprises receiving a plurality of radio samples produced by a sampling of an OFDM symbol at a reduced sampling rate, where the reduced sampling rate causes inter-symbol jitter between the plurality of OFDM symbols. The method further comprises determining a sample offset corresponding to a symbol number for the OFDM symbol, transforming the samples of the OFDM symbol into a plurality of frequency-domain resource elements, and determining a phase offset for each of the resource elements using the sample offset. The method then reduces the inter-symbol jitter by rotating each resource element using the corresponding phase offset to generate phase-rotated resource elements.

Abstract: One or more embodiments herein relate to a method for an uplink transmission timing adjustment in a wireless communication device served by a network node and configured to operate in a coverage enhancement mode. The coverage enhancement mode comprises a repetitive transmission of a first uplink signal during a first repetition period. The method comprises determining a change in a downlink timing (210), determining whether the first repetition period is ongoing (240); and in response to the change in the downlink timing and the first repetition period being ongoing, performing an adjustment of an uplink transmission timing outside the first repetition period (260).

The method comprises (during use of the radio transceiver by the first radio access control unit) indicating a worse than actual channel condition to the first network node, monitoring a change in code rate of signals transmitted from the first network node in response to the worse than actual channel condition indication, determining a relation between the worse than actual channel condition indication and the code rate change, and determining an offset value based on the determined relation. The offset value is applicable to offset a channel condition indication value to be transmitted to the first network node in association with a gap in the use of the radio transceiver by the first radio access control unit.

Abstract: 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.
