摘要： Teachings presented herein provide reduced computational complexity and/or memory requirements for a mobile terminal to determine the power backoff required for a multi-carrier uplink signal. In particular, the mobile terminal determines whether its power headroom falls below a pre-defined power headroom threshold, indicating that it is headroom limited. If so, it5 quantizes power allocated to each carrier of the multi-carrier uplink signal according to a pre-defined quantization policy. In doing so, the mobile terminal thereby reduces the possible configurations that may be selected for the multi-carrier uplink signal. Thus, in one embodiment, the mobile terminal stores the required backoff in a look-up table for only the configurations that may be selected when the mobile terminal is headroom limited. This relieves10 the memory requirements of the mobile terminal as compared to storing the required backoff for all possible configurations of the multi-carrier uplink signal.
摘要翻译：本文提出的教学提供了移动终端降低的计算复杂度和/或存储器要求，以确定多载波上行链路信号所需的功率回退。特别地，移动终端确定其功率余量是否低于预定义的功率余量阈值，指示其净空限制。如果是，则它根据预定义的量化策略量化分配给多载波上行链路信号的每个载波的功率。在这样做时，移动终端因此减少了可能为多载波上行链路信号选择的可能配置。因此，在一个实施例中，移动终端仅在移动终端被限制空间时可以选择的配置在查找表中存储所需的退避。与存储针对多载波上行链路信号的所有可能配置的所需退避相比，这减轻了移动终端的存储器要求。

摘要： A signaling mechanism is used for Dual carrier High Speed Uplink Packet Access, DC-HSUPA. The mechanism is used by a UE and RAN to allow the UE to perform secondary carrier activation or deactivation. The secondary carrier activation the deactivation performed by the UE in a manner will ensures that the UE and RAN have the same view of the current activation state. The UE transmits a request for carrier activation or deactivation to RAN over an activated carrier and awaits a positive or negative acknowledgement from RAN, or sends the signaling retroactively as a notification that a carrier has been deactivated.

摘要： The invention relates to a radio base station and method for a radio base station of a cellular communications system for controlling self- interference. The radio base station supports communication with a user equipment using multiple uplink and multiple downlink carriers. The method comprises detecting a degraded downlink performance on a downlink carrier due to self - interference by determining that a set of predefined conditions applies. The method further comprises executing, in response to detection of the degraded downlink performance, an action to reduce self - interference between the uplink and downlink carriers. The action is one of: uplink scheduling to reduce self - interference, deactivation of a secondary uplink carrier, deactivation of a secondary downlink carrier, and initiation of carrier reconfiguration to reduce self - interference. Accordingly, benefits of using multi - carrier operation may be balanced against a possible associated drawback of degraded downlink performance due to self - interference.
摘要翻译：本发明涉及用于控制自干扰的蜂窝通信系统的无线基站的无线基站和方法。无线电基站支持使用多个上行链路和多个下行链路载波与用户设备进行通信。该方法包括通过确定一组预定义条件适用来检测由于自干扰而导致的下行链路载波上的劣化的下行链路性能。该方法还包括响应于对劣化的下行链路性能的检测而执行减少上行链路和下行链路载波之间的自干扰的动作。该动作是：减少自干扰的上行链路调度，辅助上行链路载波的去激活，二次下行链路载波的去激活以及载波重配置的启动以减少自干扰。因此，使用多载波操作的好处可以与由于自干扰引起的下行链路性能下降的可能的相关缺点进行平衡。

摘要： A power control applied to a radio network controller (40) when a user equipment (300) is in communication with a serving radio base station (10) and at least one other radio base station (20) involves the radio network controller (40) providing a quality representation of an uplink control channel (12) from the user equipment (300) to the serving radio base station (10). The radio network controller (40) generates an updated power quality target for a reference control channel based on the quality representation and transmits the updated power quality target to at least one of the serving radio base station (10) and the at least one other radio base station (20). Alternatively, the radio network controller (40) generates an updated power offset for the uplink control channel (12) relative a reference control channel based on the quality representation and transmits the updated power offset to the user equipment (300).

摘要： A multi-carrier cellular radio communication system includes a serving base station associate with a serving cell currently serving a mobile radio and a non-serving base station within range of the mobile radio and associated with a non-serving cell. The mobile radio can transmit to the serving base station at the same time over multiple radio frequency carriers. An estimate is made of inter-cell interference in the non-serving cell caused by uplink transmission by the mobile radio over one or more of the multiple radio frequency carriers over which the mobile radio is currently simultaneously transmitting. If the estimated inter-cell interference in the non-serving cell exceeds a predetermined threshold, then the inter-cell interference in the non-serving cell is reduced or limited by managing radio resources so that the estimated inter-cell interference in the non-serving cell is or becomes less than the predetermined threshold.
