There is provided a signalling method for use in an advanced wireless communication network () that supports a first duplex mode, a second duplex mode different to the first duplex mode, and carrier aggregation of the first second duplex modes. This method includes configuring a UE (-) for data communication with the network () through a first access node () as a PCell, on the first duplex mode and with a first transmission mode (TM) including one or more transport blocks (TBs). This method also includes configuring the UE (-) for data communication with the network () through a second access node () as a SCell, on the second duplex mode and with a second TM including one or more TBs. The second TM associated with the second access node () is configured independently of the first TM associated with the first access node ().

A system and method of data communication is provided for use in a wireless communication system. The wireless communication system includes a base station, a relay user equipment (UE) and an out of coverage UE (OOC-UE). The method includes receiving, at the relay UE and from the base station, a relay cycle configuration, the relay cycle configuration defining a relay cycle including a first time period for device to device (D2D) communication, and a second time period for cellular communication. The method then includes receiving, at the relay UE by D2D communication, within the first time period and from the out of coverage UE (OOC-UE), relay data, and providing, from the relay UE by cellular communication, within the second time period and to the BS, the relay data.

System and method for data communication

There is provided a method in a wireless base station (), the method comprise transmitting, to a wireless device () having a reduced data bandwidth or a reduced control and data bandwidth, control and data signalling within a first bandwidth, in respective control and data regions, wherein signalling within the data region intended for the wireless device () is constrained within a second bandwidth which is narrower than the first bandwidth.

Wireless communications system and method in a wireless communications system

The present invention relates to methods that can be used in a wireless communication system, and systems adapted to use such methods. In a preferred form the methods are useful in channel estimation in a wireless communication system using orthogonal frequency division multiplexing (OFDM). The system is provided with a control block to optimize channel estimation.
