Abstract:
1. A method of operating a terminal of a wireless communication network, wherein the terminal operates according to a discontinuous reception mode and the wireless communication network comprises one or more wireless network nodes having at least first and second downlink transmission modes, comprising: detecting a cell identity for a cell associated with a wireless network node of the wireless communication system; determining a current downlink transmission mode of the wireless network node as the first or second downlink transmission mode; and adapting a time pattern based on the determined current downlink transmission mode, wherein the time pattern specifies when a receiver of the terminal is turned on, wherein: the first downlink transmission mode comprises normal operation of a particular network node and is applicable when a number of active terminals in a cell associated with the particular network node is greater than a first mode threshold value, and the second downlink transmission mode comprises restricted downlink transmission of the particular network node and is applicable when the number of active terminals in the cell associated with the particular network node is less than or equal to a second mode threshold value, the restricted downlink transmission comprising information that assists active terminals not served by the cell in finding the cell and/or non-active terminals camping on the cell to stay in synchronization with the wireless communication network.
