A method of operating an infrastructure equipment (112, 111) of a wireless communications network, the method comprising determining an allocation of a first set of communications resources (608, 604) by the infrastructure equipment acting as a first relay node (111, 112) for another infrastructure equipment acting as a second relay node, the communications resources for transmitting uplink data towards an infrastructure equipment connected to a core network part of the wireless communications network acting as a donor node, the allocation of the first set of communications resources for the other infrastructure equipment acting as the second relay node being based upon a donor set of communications resources (610, 612) allocated by the donor node for communicating the uplink data to the donor node via the infrastructure equipment acting as the first relay node (111, 112), wherein each of the infrastructure equipment (110, 111, 112, 113) are nodes having integrated access and backhaul, IAB, capability, transmitting an indication (305, 307) of the first set of communications resources to the other infrastructure equipment acting as the second relay node; transmitting to the other infrastructure equipment acting as the second relay node an activation indication indicating that at least a portion of the first set of communications resources can be used for the transmission of the uplink data by the other infrastructure equipment acting as the second relay node, wherein the activation indication is separate to the indication of the first set of communications resources, and wherein the activation indication comprises a medium access control, MAC, control element, CE; receiving the uplink data, the uplink data having been transmitted by the other infrastructure equipment acting as the second relay node using the at least the portion of the first set of communications resources; and transmitting the uplink data to the donor node using a second set of communications resources (606, 608) different from the first set of communications resources, wherein before the uplink data is transmitted by the other infrastructure equipment acting as the second relay node, the uplink data is transmitted by a first communications device. determining an allocation of a first set of communications resources (608, 604) by the infrastructure equipment acting as a first relay node (111, 112) for another infrastructure equipment acting as a second relay node, the communications resources for transmitting uplink data towards an infrastructure equipment connected to a core network part of the wireless communications network acting as a donor node, the allocation of the first set of communications resources for the other infrastructure equipment acting as the second relay node being based upon a donor set of communications resources (610, 612) allocated by the donor node for communicating the uplink data to the donor node via the infrastructure equipment acting as the first relay node (111, 112), wherein each of the infrastructure equipment (110, 111, 112, 113) are nodes having integrated access and backhaul, IAB, capability, transmitting an indication (305, 307) of the first set of communications resources to the other infrastructure equipment acting as the second relay node; transmitting to the other infrastructure equipment acting as the second relay node an activation indication indicating that at least a portion of the first set of communications resources can be used for the transmission of the uplink data by the other infrastructure equipment acting as the second relay node, wherein the activation indication is separate to the indication of the first set of communications resources, and wherein the activation indication comprises a medium access control, MAC, control element, CE; receiving the uplink data, the uplink data having been transmitted by the other infrastructure equipment acting as the second relay node using the at least the portion of the first set of communications resources; and transmitting the uplink data to the donor node using a second set of communications resources (606, 608) different from the first set of communications resources, wherein before the uplink data is transmitted by the other infrastructure equipment acting as the second relay node, the uplink data is transmitted by a first communications device.
