Abstract
An SAE/LTE or 4G cellular telecommunications network is disclosed which comprises a plurality of eNodeBs and a network core. A plurality of mobile telecommunications devices are registered with the network and communicate with the network core via the eNodeBs. A relay is provided between the eNodeB 5 and the mobile telecommunications device to extend the radio coverage provided by the eNodeB. Channel quality measurement data are transmitted to at least one of the telecommunications devices in a link with the relay to enable the telecommunications devices to calculate the channel quality between the mobile device and the relay and/or the node.
Claims16
A method of operating a mobile telecommunications network including a plurality of nodes and a network core, wherein a plurality of mobile telecommunications devices are registered with the network and communicate with the network core via the nodes, wherein at least one relay is provided between at least particular node one of said plurality of nodes and at least one particular telecommunications device of said plurality of mobile telecommunications devices to extend the radio coverage provided by the said particular node, the method comprising:
- transmitting channel quality measurement data to said particular telecommunications device in a link with the relay to enable the particular telecommunications device to calculate the channel quality between the particular telecommunications device and at least one of the relay and the particular node.
A mobile telecommunications network, comprising:
- a plurality of nodes;
- a network core;
- a plurality of mobile telecommunications devices registerable with the network and that communicate with the network core via the nodes;
- at least one relay to extend the radio coverage provided by at least one particular node of said plurality of nodes and
- a transmission device that transmits channel quality measurement data to at least one particular telecommunications device of said plurality of mobile telecommunications devices in a link with the relay to enable the particular telecommunications device to calculate the channel quality between the particular telecommunications device and at least one of;
- the relay and the particular node.
