Abstract: Systems and methods are disclosed for triggering a long range extension mode of operation for a wireless device in a cellular communications network. In one preferred embodiment, the wireless device is a Machine Type Communication (MTC) device. In one embodiment, a node in the cellular communications network determines that the wireless device is to operate in the long range extension mode if there is difficulty in establishing communication between the wireless device and the cellular communications network. If the wireless device is to operate in the long range extension mode, the node activates one or more long range extension mechanisms with respect to the wireless device such that the wireless device operates in the long range extension mode. In this manner, the long range extension mode is selectively triggered for the wireless device.

Abstract: A method in a wireless communication network for assisting a user equipment to receive signals from a target access node. The wireless communication network comprises the target access node, the user equipment and a serving access node serving the user equipment. The serving access node sends information about time instances to the user equipment. The time instances are scheduled for sending signals from the target access node in a beam direction towards the user equipments. The time instances may be determined in the target access node based on its own position and a position of the user equipment and/or a beam direction of the serving access node. The time instances may also be determined in the serving access node based on its own position and a schedule of the target access node on beam directions versus transmission times. The user equipment receives signals from the target access node during the time instances indicated in the received information.

Abstract: A method and network node for controlling power of uplink transmissions from a user node when switching between a first operating mode and a second operating mode. The network node signals to the user node a first value of a maximum allowed transmit power to be applied when operating in the first operating mode and a second value of the maximum allowed transmit power to be applied when operating in the second operating mode. The user node then uses a transmit power not exceeding the first value when transmitting radio signals in the first operating mode, and uses a transmit power not exceeding the second value when transmitting radio signals in the second operating mode. The user node itself thereby regulates the transmit power depending on opera mode without requiring further signalling from the network node.

Abstract: A method and network node (800) for controlling power of uplink transmissions from a user node (802) when switching between a first operating mode and a second operating mode. The network node (800) signals to the user node (802) a first value of a maximum allowed transmit power to be applied when operating in the first operating mode and a second value of the maximum allowed transmit power to be applied when operating in the second operating mode. The user node (802) then uses a transmit power not exceeding the first value when transmitting radio signals in the first operating mode, and uses a transmit power not exceeding the second value when transmitting radio signals in the second operating mode. Thereby, the user node (802) itself regulates the transmit power depending on operating mode without requiring further signalling from the network node (800).
