    • There is provided an energy limited node 102 for use in a communications network 100 comprising an access network node 104. The energy limited node 102 comprises a transceiver 106 operable to change its operational mode from a sleep mode in which the transceiver is not operable to communicate with the access network node to an active mode in which the transceiver is operable to communicate with the access network node; and a wake-up radio 112 comprising: a detector 302 operable to detect a received a wake-up signal from the access network node; and an identifier 304 operable to determine that the received wake-up signal corresponds to the transceiver of the energy limited node, wherein the transceiver is operable to change its operation mode from a sleep mode to an active mode upon determination that the received wake-up signal corresponds to the transceiver.

    • A method and network node for controlling operation of first and second wireless communication networks both operating in a predetermined frequency band.
      The first communication network is operable to communicate within a plurality of first network channels within the predetermined frequency band. The second communication network is operable to communicate within at least one second network channel within the predetermined frequency band.
      Each of the second network channels co-exist in a frequency range occupied by a plurality of the first network channels.
      The method comprises the steps of:
      determining that there may be data to be communicated within a network channel of one of the first and second wireless communication networks,
      transmitting a channel restriction message to another of the first and second wireless communications networks, the channel restriction message instructing prevention of communication within the another of the first and second wireless communications networks on at least one network channel in the another of the first and second wireless communications networks coexisting in a frequency range occupied by the network channel; and
      instructing communication within the one of said first and second wireless communications networks on said channel.
    • 一种用于控制在预定频带中操作的第一和第二无线通信网络的操作的方法和网络节点。 第一通信网络可操作以在预定频带内的多个第一网络信道内进行通信。 第二通信网络可操作以在预定频带内的至少一个第二网络信道内进行通信。 每个第二网络信道在由多个第一网络信道占据的频率范围内共存。 该方法包括以下步骤:确定可能存在要在第一和第二无线通信网络之一的网络信道内通信的数据,向第一和第二无线通信网络中的另一个发送信道限制消息,信道限制 消息指示防止第一和第二无线通信网络中的另一个中的另一个中的通信在第一和第二无线通信网络中的另一个在由网络信道占据的频率范围中共存的另一个网络信道上; 以及指示所述信道上的所述第一和第二无线通信网络之一内的通信。
