摘要： An ARQ (re-) transmission method of transmitting data in a wireless communication system wherein data packets are transmitted from a transmitter to a receiver, using a first transmission and a second transmission based on a repeat request. The method comprises the steps of modulating data at the transmitter using a first signal constellation pattern to obtain a first data symbol. The first data symbol is transmitted as the first transmission to the receiver using a first diversity branch. Further, the data is modulated at the transmitter using a second signal constellation pattern to obtain a second data symbol. Then, the second data symbol is transmitted as the second transmission to the receive over a second diversity branch. Finally, the received first and second data symbol data symbol are diversity combined at the receiver. The invention further relates to a transmitter and a receiver embodied to carry out the method of the invention.

摘要： A wireless communication terminal apparatus and a CQI selecting method wherein when CQIs are grouped according to their levels and then an upper-order CQI, which is indicative of a group, is to be informed in a longer period, while a lower-order CQI, which identifies a CQI in the group, being to be informed in a shorter period, the CQI is precisely selected. A reception SIR range of 0-4 dB in UE corresponds to a level 1 of upper-order CQI. A next reception SIR range of 4-8 dB corresponds to a level 2 of upper-order CQI. Similarly, the following SIR ranges up to 24 dB, each of which is 4 dB higher than a respective previous one, correspond to the respective following levels of upper-order CQI. On the other hand, the levels 1-4 of lower-order CQI, with which the level 1 of upper-order CQI is associated, correspond to a SIR range of −1-5 dB. The levels 1-4 of lower-order CQI, with which the level 2 of upper-order CQI is associated, correspond to a SIR range of 2-9 dB. Thus, the SIR ranges, to which the lower-order CQIs correspond, overlap the respective SIR ranges corresponding to the respective adjacent levels of upper-order CQIs with which the lower-order CQIs are associated.
摘要翻译：一种无线通信终端装置和CQI选择方法，其中当CQI被根据其级别分组，然后是指示组的高阶CQI将被更长时间通知时，而低阶CQI，其识别组中的CQI，在较短的周期内被通知，精确地选择CQI。 UE中0-4dB的接收SIR范围对应于高阶CQI的1级。 4-8dB的下一个接收SIR范围对应于高阶CQI的2级。类似地，高达24dB的以下SIR范围对应于上一级CQI的各个后续级别，每个高达24dB的每一个高于相应的前一个。另一方面，高阶CQI的等级1与其相关联的低阶CQI的级别1-4对应于-1.5dB的SIR范围。与高阶CQI的2级相关联的低阶CQI的级别1-4对应于2-9dB的SIR范围。因此，低阶CQI对应的SIR范围与对应于低阶CQI相关联的高阶CQI的各个相邻级别的各个SIR范围重叠。

摘要： The invention relates to a method and a receiver for demodulating a modulation symbol in a communication system without knowledge of the modulation constellation employed in a transmitter to modulate this symbol before transmission. According to the method, the invention comprises the steps of interpreting the modulation symbol as a symbol of one of a family of hierarchical modulation constellations, decoding the demodulated symbol using a forward error correction (FEC) technique and demodulating the symbol according to the assumed modulation constellation. Finally, the demodulated symbol is checked for correctness. The receiver comprises of a corresponding interpretation unit, a demodulator and an FEC decoder as well as means for checking the correctness of the demodulated symbol.

摘要： A method is disclosed for use in wireless communication systems employing dynamic resource allocation schemes (Dynamic Channel Allocation, DCA) together with Link Adaptation (LA) schemes. The method allows to provide individually optimized Quality of Service to each of a plurality of services. This is achieved by exclusively mapping data belonging to one single service to a Physical Data Block. Based on information about the packets, the services and/or the shared physical channels, scheduling metrics are calculated, based upon the scheduling metrics it is decided which of said services is to be served next. Therefore, it is possible to adapt the transmission parameters of physical channels individually to the required Quality of Service of data transmitted over the channel. As a further advantage, the transmission capacity of the physical channel can be economically utilized.

摘要： A hybrid ARQ retransmission method involves encoding data packets with a forward error correction (FEC) technique prior to transmission. The data packets are retransmitted based on an automatic repeat request and subsequently soft-combined with previously received erroneous data packets either on a symbol-by-symbol or a bit-by-bit basis. The symbols of the erroneous data packets are modulated by employing a first signal constellation. The symbols of the retransmitted data packets are modulated by employing at least a second signal constellation. Each symbol bit has a mean bit reliability defined by the individual bit reliabilities over all symbols of the predetermined signal constellation. The first constellation and the at least second signal constellation are selected such that the combined mean bit reliabilities for the respective bits of all transmissions are averaged out.
