摘要： An attenuator control method of a signal processing chain comprising two or more signal processing units is disclosed. One of the two or more signal processing units is a signal attenuator adapted to apply adaptive signal attenuation of an attenuator input signal based on one or more attenuation parameters to provide an attenuator output signal. At least one of the two or more signal processing units has an associated wearout process and a corresponding wearout budget, wherein a wearout event of the wearout process occurs when a level of a wearout indication signal of the signal processing chain is in a wearout region, and wherein the wearout process is modeled by a wearout event cost associated with a corresponding wearout event. The method comprises obtaining an indication of whether a wearout event of the wearout process has occurred. If the obtained indication shows that a wearout event of the wearout process has occurred, the method comprises updating a wearout accumulation metric of the wearout process by the associated wearout event cost, comparing the wearout accumulation metric of the wearout process with one or more wearout thresholds of the wearout process, and adapting the attenuation parameters of the signal attenuator based on the comparison. The method also comprises controlling the signal attenuator based on the attenuation parameters. Corresponding attenuator control arrangement is also disclosed.
摘要翻译：公开了包括两个或更多个信号处理单元的信号处理链的衰减器控制方法。两个或更多个信号处理单元中的一个是信号衰减器，其适于基于一个或多个衰减参数应用衰减器输入信号的自适应信号衰减以提供衰减器输出信号。两个或更多个信号处理单元中的至少一个具有相关联的磨损过程和相应的磨损预算，其中磨损过程的磨损事件发生在信号处理链的磨损指示信号的水平处于磨损区域中时，并且其中所述磨损过程由与相应的磨损事件相关联的磨损事件成本建模。该方法包括获得是否发生磨损过程的磨损事件的指示。如果所获得的指示示出磨损过程的磨损事件已经发生，则该方法包括通过相关磨损事件成本来更新磨损过程的磨损累积度量，将磨损过程的磨损累积度量与一个或多个磨损阈值进行比较的磨损过程，并根据比较结果调整信号衰减器的衰减参数。该方法还包括基于衰减参数来控制信号衰减器。也公开了相应的衰减器控制装置。

摘要： Adaptation is introduced into allocation of uplink and downlink subframes in wireless communication systems that support full-duplex and half-duplex mobile terminals, thus reducing interference between mobile terminals. In an exemplary method for allocating uplink and downlink timeslots in a wireless communication system supporting full-duplex and half-duplex mobile terminals, a base station determines that a mobile terminal is capable of only half-duplex operation and allocates one or more uplink subframes and one or more downlink subframes to the first mobile terminal, for each of a plurality of frames, so that none of the allocated uplink subframes overlaps in time with an allocated downlink subframe. The allocation of uplink subframes and downlink subframes is varied between consecutive ones in at least a first series of frames according to a pre-determined pattern. In some embodiments, the method further includes transmitting an allocation message to the first mobile terminal, designating the pre-determined pattern.

摘要： A radio communication system that utilizes an available frequency spectrum that is divided up into a plurality of channels to be used by the radio communication system is operated in accordance with a frequency hopping strategy that permits a user to simultaneously utilize more than one channel during each hop period, wherein it is permissible, but not mandatory, for at least one of the channels utilized by the user during a first hop period to again be used by the user during an immediately following second hop period, so long as at least one of the channels utilized by the user during the second hop period is different from all of the channels utilized by the user during the first hop period. In some embodiments, the number of channels simultaneously utilized by any one user need not be the same as the number of channels simultaneously utilized by any other user.
