    • In a communication system using aggregation of component carriers, a transmitter (210) comprises a transmitting entity (212) configured to transmit data messages (21) on multiple component carriers. The transmission of the data messages (21) is accomplished on the basis of a retransmission protocol. The retransmission protocol requires sending of an acknowledgement message (22) in response to verifying correct receipt of a data message (21). A receiver (220) comprises a receiving entity (222) configured to receive the data messages (21) on the basis of the retransmission protocol. In response to a decision to deactivate transmission on one of the aggregated component carriers, the retransmission protocol is triggered to retransmit those data messages (21) for which no acknowledgement message (22) of the retransmission protocol has been received. The retransmission is accomplished on at least one other of the component carriers. A further retransmission protocol may be used on each of the component carriers, with respective transmitting entities (214, 216) in the transmitter (210) and respective receiving entities (224, 226) in the receiver (220).
    • 在使用分量载波的聚合的通信系统中,发射机(210)包括被配置为在多个分量载波上发射数据消息(21)的发射实体(212)。 数据消息(21)的传输是基于重传协议完成的。 响应于验证数据消息(21)的正确接收,重传协议要求发送确认消息(22)。 接收器(220)包括被配置为基于重传协议接收数据消息(21)的接收实体(222)。 响应于去激活聚合分量载波之一上的传输的决定,触发重发协议以重新发送没有接收到重发协议的确认消息(22)的那些数据消息(21)。 重传在至少另一个分量载波上完成。 可以在每个分量载波上使用另外的重传协议,其中发射机(210)中的相应发射实体(214,216)和接收机(220)中的相应接收实体(224,226)。

    • The disclosure relates to a network node of a wireless network, and to a related method of controlling interference generated by at least one white space device controlled by the network node. The method comprises transmitting (520) a request for information regarding channels available for secondary usage to the remote entity, and receiving (530) information from the remote entity, the information indicating a channel available for secondary usage, a critical position associated with said channel, and an interference threshold for the critical position. The method also comprises deriving (540) a constraint for the allocation of said channel to the at least one white space device, based on a position of the at least one white space device, the critical position, and the interference threshold, and allocating (550) said channel and a transmit power to the at least one white space device based on the derived constraint, whereby the interference generated in the critical position by the at least one white space device is kept below the interference threshold.

    • The disclosure relates to a white space device (WSD) of a secondary wireless network, and to a related method for transmitting a first signai on a channel available for secondary usage allocated to a primary wireless system. The method in the WSD comprises determining (410) a further channel used by the primary wireless system, that would be interfered by a transmission of the first signal on the channel available for secondary usage, retrieving (420) signai information associated with the determined further channel from the primary wireless system, transmitting (430) the first signal on the channel available for secondary usage, and transmitting (440) a second signal on the determined further channel based on the retrieved signal information, simultaneously with the first signal on the channel available for secondary usage* such that an interference generated in the primary wireless system by the first signal transmission is compensated for by the second signal transmission.
    • 本公开涉及二次无线网络的白空间设备(WSD)以及用于在可用于分配给主无线系统的次要使用的信道上发送第一信号的相关方法。 WSD中的方法包括确定(410)由主无线系统使用的另一信道,其将被可用于二次使用的信道上的第一信号的传输干扰,检索(420)与所确定的进一步相关联的信息信息 发送(430)可用于二次使用的信道上的第一信号,以及基于所检索的信号信息,在所确定的另一信道上发送(440)第二信号,同时与信道上的第一信号 可用于次要使用*,使得通过第一信号传输在主无线系统中产生的干扰由第二信号传输补偿。
