Methods and infrastructure equipment

A first infrastructure equipment for operating in a wireless communications network, the wireless communications network comprising a core network part, a second infrastructure equipment, the first infrastructure equipment acting as a backhaul relay node between the second infrastructure equipment and the core network part, and a downstream wireless communications device, the first infrastructure equipment comprising:

• a transmitter to transmit radio signals via a wireless access interface of a radio access network part of the wireless communications network,
• a receiver to receive radio signals transmitted via the wireless access interface of the radio access network part, and
• a controller configured to control the transmitter
• to transmit to the second infrastructure equipment an indication of a first set of communications resources, the first set of communications resources comprising one or more resource elements of a first frequency resource within a first time period, the first set of communications resources being available for allocating by the second infrastructure equipment for a transmission of first data from a downstream wireless communications device different from the first infrastructure equipment to the second infrastructure equipment, for transmission to the core network part, and
• to transmit second data to the second infrastructure equipment on one or more resource elements of the first frequency resource within a second set of communications resources within the first time period, the second set of communications resources different from the first set of communications resources.
