摘要： The present invention provides methods and devices for mitigating inter-cell interference in communication environments having a plurality of cells. In some embodiments, a time-frequency transmission resource that includes multiple sub-carriers over multiple OFDM symbol intervals is partitioned into a first zone and a second zone. In the first zone, transmissions are transmitted on at least one frequency sub-band which is common to all of the plurality of cells. In the second zone, transmissions are transmitted on at least one frequency sub-band which is used by less than all of the plurality of cells, so as to mitigate inter-cell interference. In some embodiments, in the first zone transmissions are transmitted using a transmission power which is common to all of the plurality of cells and in the second zone transmissions are transmitted using a transmission power which is used by less than all of the plurality of cells so as to mitigate inter-cell interference.

摘要： The invention concerns a method which consists in allocating to a base station, at a control member of the base station, a list of channels shared by several terminals containing several sets of shared channels. For a communication session between the base station and a specific terminal, it consists in indicating to the terminal the list of shared channels allocated to the base station. At the base station, it consists in selecting for the terminal one of the sets of shared channels, and independently of the control member, indicating the selected set to the terminal via a dedicated channel.

摘要： A scheme for multiplexing transport channels on one or several communication channels is used to operate in a normal mode and in a compressed mode which requires a lower symbol rate to provide in active periods in the communication channels. To match the symbol rate on each of the transport channels, a symbol puncturing is performed in two passes: marked symbols are introduced and are subjected, along with the other information symbols, to different operations including an interleaving, before being deleted from the transmitted sequence. Accordingly, those operations can be performed in the same manner in the normal and compressed modes, which limits the complexity of the communicating entities.
摘要翻译：用于在一个或多个通信信道上复用传输信道的方案被用于在正常模式和压缩模式下操作，该压缩模式需要较低的符号率来在通信信道中提供活跃的时段。为了匹配每个传输信道上的符号速率，在两遍中执行符号删截：在从所发送的序列中删除之前，将标记符号与其他信息符号一起进行包括交织的不同操作。因此，这些操作可以以相同的方式在正常和压缩模式中执行，这限制了通信实体的复杂性。

摘要： A mobile radio system enables exchange of bidirectional digital signals between at least one mobile station and at least one base transceiver station and provides at least two coding modes, each mode corresponding to a predetermined source code and a predetermined channel code for the transmission of a wanted signal for each transmission direction. Each source code corresponds to a given user bit rate and each channel code corresponds to a given coding efficiency and therefore to a given total bit rate for a given source code. For adaptation of the air interface of this system, at the time of a call between a mobile station and a base transceiver station, two separate analyses of transmission quality are carried out for each transmission direction, respectively, and, for each transmission direction, one of the coding modes is selected in accordance with the corresponding transmission quality analysis.
