摘要： It is provided a method, comprising monitoring if a sent packet is acknowledged as correctly received; checking, if the sent packet is not acknowledged as correctly received, if retransmitting the sent packet at a time interval determined for retransmission is admitted; informing, if the retransmitting at the determined time interval is not admitted, that the sent packet is not acknowledged as correctly received.

摘要： Conventionally, all active UEs monitor an absolute grant channel. When a transmission from an eNB occurs, each UE tries to decode the grant message (e.g. by performing a CRC check with its E-RNTI, which is associated uniquely to each UE in the cell). If a UE successfully decodes the grant, it starts a grant update procedure, setting its Serving Grant to the value indicated in the grant message. The eNB then sends a further grant command indicating a Serving Grant value of zero to the other UEs, in order to silence them. According to the invention, any UE which receives an absolute grant that is not intended for it (e.g. the CRC check fails) automatically sets its Serving Grant to zero. This way a single grant command provides an absolute grant for one UE and at the same time silences other UEs in a cell. The eNB does not need to send the further grant command to UEs other than the one for which the absolute grant is intended. With respect to the conventional art, the signalling overhead is thus reduced and the problem of not utilized TTIs (because only one absolute grant may be transmitted per TTI) is solved.
