Methods, systems, and devices for wireless communication are described. A relay wireless node may receive, during a first transmit time interval (TTI), a data message to be forwarded to a wireless node. The relay wireless node may forward the data message to the wireless node during the first TTI. The relay wireless node may receive, during a second TTI, a feedback message from the wireless node. The relay wireless node may retransmit the feedback message during the second TTI.

A method of securing wireless backhaul for a child base station in a first network provided by a first operator, including: any parent base station with wireline backhaul capability and configured to virtualise a core network User Plane Function, UPF, advertises that it supports a wireless backhaul service; the child base station in the first network connects over an air interface to one or more parent base stations in a second network provided by a second operator; the child base station sends a backhaul service request to a connected parent base station; when the backhaul service request is accepted, the connected parent base station uses a virtualised UPF to enable a direct wireline backhaul link between the parent base station and a data network; and the child base station uses the air interface as a wireless backhaul link and the wireline backhaul link of the connected parent base station for backhaul.

The present invention relates to a method for configuring a retransmission protocol on the uplink between a network node and a relay node in a mobile communication system, the configuration being performed at a network node or at a relay node, and to the corresponding relay node apparatus and network node apparatus capable of configuring the retransmission protocol. In particular, the number of transmission processes is determined based on the position of time intervals available for the transmission and may be selected in order to control the round trip time of the retransmission protocol. Once the number of transmission processes has been configured, the transmission processes are mapped on the available time intervals in a predefined order and repetitively.

A method for informing a relay node when to receive data. The method includes the relay node being informed of a fixed point in a subframe of data when an access node will begin transmitting relevant data over a physical downlink shared channel. The method further includes the relay node beginning to receive data at approximately the fixed point.
