    • The present invention relates to a methods and devices for use in multi carrier communication systems in which secondary downlink and secondary uplink carriers may be dynamically activated/deactivated by means of transmitting an HS-SCCH order (23) from a radio base station (21) to a user equipment (22). The HS-SCCH order (23) is encoded by the radio base station (21) according to an order mapping. The order mapping maps a desired activation status of a set of carriers to a corresponding encoded HS-SCCH order. The user equipment (22) interprets the encoded HS-SCCH order (23) to derive the desired activation status of the set of carriers. By using an appropriate order mapping, operations in the radio base station and/or the user equipment may be simplified, e.g. by allowing the radio base station (21) to calculate the encoded HS-SCCH order (23) based on the desired activation status.
    • 本发明涉及一种用于多载波通信系统的方法和装置,其中可以通过从无线电基站(21)发送HS-SCCH命令(23)来动态地激活/去激发次级下行链路和辅助上行链路载波, 到用户设备(22)。 HS-SCCH顺序(23)由无线基站(21)根据顺序映射进行编码。 顺序映射将一组载波的期望激活状态映射到对应的编码HS-SCCH顺序。 用户设备(22)解释编码的HS-SCCH顺序(23)以导出该组载波的期望激活状态。 通过使用适当的顺序映射,可以简化无线电基站和/或用户设备中的操作。 通过允许无线电基站(21)基于期望的激活状态来计算编码的HS-SCCH顺序(23)。
