摘要： A method is provided which improves reliability of channel estimation in a digital communication system by reducing the ambiguity in the recognition of received symbols evaluated for the channel estimation. A data word transmitted according to a first mapping of data word values to modulation states is re-transmitted at least once with a second, re-arranged mapping of data word values to modulation states. The second mapping and possible further mappings are generated from the first mapping in a way that the number of different results which can be obtained from combining the transmitted original data symbol and the re-transmitted counterpart data symbol(s) is lower than the number of original modulation states in the first mapping.

摘要： The present invention relates to a method for balancing the distribution of interference between radio cells in a wireless communication system comprising cells in which subcarrier blocks are used for communication. A number of adjacent cells build a cell cluster. Moreover, the present invention relates to a corresponding method adapted for use in a system in which multi beam antennas or multiple antennas are used. Furthermore, the present invention relates to base stations performing the above method as well as a communication system comprising the base stations. To reduce the large average SIR variations without causing additional SIR estimation, measurement and calculation problem as introduced with power control the invention suggests to group subcarrier blocks into a plurality of subcarrier block sets in each cell of a cell cluster, to determine transmission power ranges for each of the cells of said cell cluster, and to assign transmission power ranges to the subcarrier block sets to perform TPC within the ranges.

摘要： The invention relates to a method for receiving data units when using one HARQ process of an HARQ protocol. The memory associated to the HARQ process is divided into several sub-areas, which are addressable by an identifier. Then, when data is received, same is stored in one of the sub-areas. By providing more than one sub-area for one HARQ process, it is possible to actually use one HARQ process for two (or more) different received data units, being from the same data flow or from a different data flow. The actual sub-area of the HARQ process for storing data units can be either freely selected at the receiving end or is indicated by an identifier associated with the data. Furthermore, persistent scheduled data is transmitted in units, scheduled at fixed time intervals. Thus, a control signaling field, usually used for indicating new units, can be used to store the identifier.

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 for providing control signalling associated to a protocol data unit conveying user data in a mobile communication system and to the control channel signal itself. Furthermore, the invention also provides a mobile station and a base station and their respective operation in view of the newly defined control channel signals defined herein. In order to reduce the control channel overhead, the invention suggests defining a common field for the transport format and redundancy version in the control channel information format. According to one approach, the common field is used to jointly encode transport format and redundancy version therein. According to another aspect, one shared field is provided on the control channel signal that indicates either a transport format or a redundancy version depending of whether the control channel signal relates to an initial transmission or a retransmission. In another embodiment, further enhancements to a HARQ protocol are suggested for addressing certain error cases.

摘要： Provided is a wireless communication apparatus wherein channel estimation accuracy is improved while keeping the position of each bit in a frame, even when a modulation system having a large modulation multiple value is used for a data symbol. In the wireless communication apparatus (100), an encoding section (101) encodes and outputs transmitting data (bit string) to a bit converting section (102), and the bit converting section (102) converts at least one bit of a plurality of bits constituting a data symbol to be used for channel estimation, among the encoded bit strings, into ‘1’ or ‘0’ and outputs it to a modulating section (103). The modulating section (103) modulates the bit string inputted from the bit converting section (102) by using a single modulation mapper and a plurality of data symbols are generated.

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.
