    • A method of controlling operation of a communication device arranged to operate in a cellular communication network employing a paging signal to allow discontinuous reception for communication devices is disclosed. The communication device is arranged for three main communication states: detached state where the communication device is not registered to the cellular communication network; idle state where the communication device is registered to the cellular communication network, and receives paging signals through discontinuous reception; and active state where the communication device is registered to the cellular communication network and performs communication with the cellular communication network essentially continuously. The method comprises: i) connecting to the cellular communication network such that a transition from the detached state to any of idle state or active state is made; ii) performing scheduled operations in the active state or idle state; iii) determining, when a transition from the active state to the idle state occurs, time instant for next operation in the active state; iv) disconnecting from the cellular communication network such that a transition to the detached state is made; and v) when the time for next operation in the active state is approaching, returning the procedure to step i). A transceiver and a computer program are also disclosed.

    • Data Block Transmission with Variable Retransmission Feedback Time For communicating data between a transmitter (10) and a receiver (14), wireless transmission of data blocks is implemented on the basis a retransmission protocol with variable value of a feedback time. The feedback time defines a time interval between transmission of one of the data blocks (22) and transmission of a feedback message (23) indicating whether the data block (22) was successfully received. The transmitter (10) or the receiver (14) determines the value of the feedback time. Depending on the determined value of the feedback time, the transmitter (10) controls transmission of the data block (22) to the receiver and/or the receiver (14) controls reception of the data block (22) at the receiver (14). The transmitter (10) may for example be a base station of a mobile network, and the receiver (14) may be a terminal device connected to the mobile network. (Fig. 1)
    • 具有可变重发反馈时间的数据块传输对于在发射机(10)和接收机(14)之间传送数据,数据块的无线传输是基于具有反馈时间可变值的重传协议实现的。 反馈时间定义了一个数据块(22)的传输和表示数据块(22)是否被成功接收的反馈消息(23)的发送之间的时间间隔。 发射机(10)或接收机(14)确定反馈时间的值。 根据确定的反馈时间值,发射机(10)控制数据块(22)向接收机和/或接收机(14)的传输,控制接收机(14)处的数据块(22)的接收, 。 发射机(10)可以例如是移动网络的基站,并且接收机(14)可以是连接到移动网络的终端设备。 (图。1)

    • A relay node is operated in a communication system wherein the relay node communicates with a communication system node via a first link and communicates with user equipment (EU) via a second link. The relay node detects whether a collision between its own uplink transmission on the first link and receipt of the user's transmission on the second link at a future time instant is expected to occur, wherein the collision will interfere with the relay node's ability to receive the UE's transmission. If so, then, the relay node selects and executes one of a plurality of interference averting measures, selection being based at least in part on what type of information is expected to be transmitted and received on the respective first and second links. First and second interference averting measures comprise refraining from or proceeding with transmission of some information to the communication system node.
    • 中继节点在通信系统中操作,其中中继节点经由第一链路与通信系统节点进行通信,并经由第二链路与用户设备(EU)进行通信。 中继节点检测是否发生自己在第一链路上的上行链路传输与未来时刻在第二链路上接收用户传输之间的冲突,其中冲突将干扰中继节点接收UE的上行传输的能力 传输。 如果是,则中继节点选择并执行多个干扰避免措施中的一个,至少部分地基于期望在相应的第一和第二链路上发送和接收什么类型的信息。 第一和第二干扰避免措施包括避免或继续向通信系统节点传送一些信息。
