摘要： The invention relates to a method for deactivating a semi-persistent resource allocation of a user equipment in an LTE-based mobile communication system. Furthermore, the invention also related to a user equipment and a eNode B implementing this method. To provide a mechanism for deactivating a semi-persistent resource allocation in a LTE system which is not requiring any changes to the Physical layer-to-MAC layer interface and/or preferably no changes to the PDCCH formats agreed by the 3GPP a combination of NDI value and MCS index is defined that is commanding the release of SPS resources. Alternatively, another solution proposed to define a special transport block size that when signaled in a PDCCH is commanding the release of SPS resources.

摘要： A method is disclosed for digital data transmission using higher order modulation schemes, wherein a plurality of bits is mapped to bit positions of a symbol and the transmission has different error probabilities for at least two out of said bit positions. A data bit is mapped to a bit position in a first modulation scheme and transmitted in a symbol on the mapped bit position of the first modulation scheme. When a request is received from a receiver, for re-transmission of a data block containing this data bit, a decision is made about a re-transmission of said bit, based on a reliability of the bit position in the first transmission, and if it is decided to retransmit the bit, the data bit is mapped to a bit position of a second modulation scheme and retransmitted in a symbol on the mapped bit position of the second modulation scheme.

摘要： The invention relates to a method for transmitting data packets between an eNodeB and a mobile node (MN) when simultaneously using the HARQ protocol with soft-combining for unicast and multicast transmissions. Unicast transmissions are assigned to HARQ processes by the eNB, whereas multicast transmissions need to be assigned to a HARQ process by the MN. According to a first aspect, the soft-buffer memory is strictly separated into a unicast and multicast section, and HARQ protocol operations for unicast and multicast are independent. Due to the separation, the eNB can still correctly assign the unicast transmissions to a HARQ process. According to a second aspect, the soft-buffer is not separated but commonly used for unicast and multicast. However, in order for the eNB to still be able to correctly assign the unicast transmissions to a free HARQ process, the MN assigns the multicast transmission depending on a rule, known also to the eNB.

摘要： A radio transmitting apparatus and the like for improving the reception error rate characteristic. In this apparatus, a data modulating part (121) modulates a data signal to provide a modulated symbol. A Q-inverting part (125) generates a symbol that corresponds to the modulated symbol provided by the data modulating part (121) and that, when combined with the modulated symbol, becomes a signal having a particular value. A multiplexing part (110) multiplexes the modulated symbol provided by the data modulating part (121) with the corresponding symbol generated by the Q-inverting part (125) to provide a multiplexed signal.
