Methods and network nodes (700-720) route communications between pairs of source and destination nodes through network nodes (700-720) of a wireless communication system. One resource slot of a wireless communication link is selected (1200) between each of a sequence of the network nodes (700-720) along a communication route between one pair of the source and destination nodes. Another resource slot of the wireless communication link is selected (1202) between at least some of the sequence of the network nodes (700-720) along the communication route between the one pair of the source and destination nodes. Selection of the other resource slot between each of the sequence of the network nodes along the communication route can be constrained to selection among resource slots that are available from only the sequence of the network nodes along the communication route between the one pair of the source and destination nodes.
