摘要： A method comprising receiving, at a first infrastructure equipment of a wireless network, a command from a second infrastructure equipment comprising an indication that a downlink message for a communications device to decode should be transmitted by the first infrastructure equipment and that a wake-up signal should be transmitted by the first infrastructure equipment to the communications device in advance of transmitting the downlink message, and transmitting the wake-up signal to the communications device in advance of transmitting the downlink message to provide the communications device with an indication that the downlink message for the communications device to decode will be transmitted. The wake-up signal comprises a preamble formed by a plurality of Orthogonal Frequency Division Multiplexed, OFDM, symbols, each of the OFDM symbols being modulated with a reference sequence.

摘要： A terminal device and a method of operating a terminal device in a wireless communication network. The method comprises establishing, by the terminal device, a first radio connection with a first network access node for transmission of data via a first bearer and a second radio connection with the first network access node for transmission of data via a second bearer. Based on a difference between quality of service for the data transmission via the first bearer and the second bearer, a third radio connection is established between the terminal device and a second network access node for transmission of the data via the first bearer; and the third radio connection is established between the terminal device and the second network access node, a fourth radio connection is established between the terminal device and the second network access node for transmission of the data via the second bearer.

摘要： A terminal device configured to receive a radio signal from which measurements can be used to assist in determining a position of the terminal device. The terminal device detects one or more system information blocks carrying position assistance information transmitted from the infrastructure equipment and estimates the position of the terminal device by combining the identified position assistance information with the radio signal received by the position detection receiver circuitry. Furthermore the terminal device receives from the infrastructure equipment an indication of relative risk that the position assistance information will change, and in response to the indication of the relative risk that the position assistance information will change to adapt the receiving of the one or more system information blocks to receive an updated version of the position assistance information in accordance with the relative risk.
