1. A method comprising:
- generating, for a relay node, an indication of a configuration of a subframe of at least one of an uplink and a downlink of a backhaul; and
sending the indication to the relay node to configure transmission at the relay node in accordance with the configuration of the subframe, wherein the indication is generated using multi-periodicity semi-persistent scheduling, wherein the relay node is coupled to a base station transmitting the indication, and wherein the backhaul and an access link from the relay node are configured for time division multiplex communications.

Abstract
Methods and apparatus, including computer program products, are provided for indicating the configuration of a subframe of a backhaul between a relay node and a base station. In one aspect there is provided a method. The method may include generating an indication of a configuration of a subframe of at least one of an uplink and a downlink of a backhaul and sending the indication to a relay node to configure transmission at the relay node. Related apparatus, systems, methods, and articles are also described.
