摘要： Embodiments herein relate to a method performed by a radio node (13) for managing communication of one or more wireless devices (10) within a wireless communication network (1); which wireless communication network (1) comprises a radio access network node (12) serving the radio node (13). The radio node (13) receives an indication of radio resources out of a total spectrum of radio resources controlled by the radio access network node (12) for communication over a first radio interface using a first radio access technology, which indicated radio resources are allocated to the radio node (13) from the radio access network node (12) for communication over a second radio interface, which second radio interface uses a second radio access technology being different than the first radio access technology. The radio node (13) allocates at least part of the indicated radio resources for communication to and/or from the one or more wireless devices (10) over the second radio interface.

摘要： A first network node, a second network node and methods therein, for handling baseband processing of signals communicated with wireless devices in a wireless network. The first network node communicates a first type of signals with a first wireless device and performs a first part of baseband processing of the first type of signals using a non-GPP implemented processor. The first network node also communicates the first type of signals with the second network node for a second part of baseband processing of the first type of signals using a GPP implemented processor. The first network node further communicates a second type of signals with a second wireless device and performs both of said first and second parts of baseband processing of the second type of signals using the non-GPP implemented processor.

摘要： A method, system and apparatus are disclosed. A network node and a wireless device configured to communicate in a communication system are provided. The communication system having narrowband multi-carrier operation. The network node including processing circuitry configured to receive in an uplink control information field an indication of a downlink channel quality for at least one of a plurality of carriers used by the wireless device in a radio resource control, RRC, connected mode. The wireless device including processing circuitry configured to trigger an indication of a downlink channel quality in an uplink control information field and cause transmission of the indication to a network node.

摘要： A method in a first base station in a communications network for performing channel estimation of a first wireless channel between a first wireless device and the first base station. A signal comprising a first component is received over the first wireless channel, the first component corresponding to a first reference signal transmitted by the first wireless device to the first base station, and a second component, wherein at least part of the second component corresponds to a second reference signal transmitted by a second wireless device to a second base station. Also, receiving scheduling information according to which the second wireless device is scheduled to transmit the second reference signal to the second base station; generating, a constructed reference signal representative of the second reference signal; and performing channel estimation of the first wireless channel between the first wireless device and the first base station.
