Abstract: The present invention discloses a method for controlling transmission power in real time of a wireless communication system having at least one local access point and a plurality of remote access points. Preferably, the method involves calculating (101) the estimated RSS and scans (104) for the actual RSS. Consequently, the interference of each access point is defined through the comparison of the actual and estimated RSS. Also, the interference of each access point will be analyzed (200) and lastly followed by adjusting (300) the transmission power of each access point according to the interference analysis.

Abstract: The application relates to scheduling of data traffic with regard to Quality of Service, QoS, in particular for the scheduler between the MAC and PHY layer in Mobile WiMAX. Different traffic priority is transmitted using the available channel in the system and it is currently not based on transmission channel condition. In practice, some channels are better than the others, but not all traffic are of the same priority. The problem occurs when high priority traffic may be assigned to bad channel condition. This will result in poor signal quality at receiver. For instance, the high priority traffic may require low delay. However, if it is transmitted using a bad channel then the received signal will suffer in high error rate and transmission loss. This problem is also due to lack of inter-layer communication in wireless system. This problem is solved in that the scheduler (CH-Allocation) allocates the traffic not only according to QoS but also according to the time- varying channel conditions (QoT).

Abstract translation: 该应用涉及关于服务质量，QoS的数据业务的调度，特别是对于移动WiMAX中的MAC层和PHY层之间的调度器。 使用系统中的可用信道来传输不同的业务优先级，目前不是基于传输信道条件。 实际上，一些渠道比其他渠道好，但不是所有的流量都是同等的优先。 当高优先级流量可能被分配给不良信道条件时，会发生此问题。 这将导致接收机的信号质量差。 例如，高优先级流量可能需要低延迟。 然而，如果使用坏信道发送，则接收到的信号将以高错误率和传输损耗而遭受损失。 这个问题也是由于无线系统中缺乏层间通信。 这个问题的解决是，调度器（CH分配）不仅根据QoS分配业务，而且根据时变信道条件（QoT）分配流量。

Abstract: The present invention relates to a method to improve signal quality in a communication network, more particularly for error data detec¬ tion and correction. One of the advantages of the method to improve signal quality in a communication network of the present invention is that no additional and dedicated bandwidth is required. Furthermore, the method to improve signal quality in a communication network of the present invention will not delay the communication such as in the technique of informing the transmitter back and forth. In system such as time-division multiple access (TDMA), the time slot provided for transmitting user data will reduce the time used to retransmitting the same data over and over again and increase the efficiency when is used for retransmitting the same data.
