The resource configuration comprises information defining at least one resource type for a plurality of links for at least one time and at least one resource. The method comprises allocating, in dependence on the resource configuration, the at least one resource for said at least one time to at least one link of the plurality of links, the at least one link being with one or more child nodes. ## Claims ### Claim at position 1 1-25. (canceled) ### Claim 26 An apparatus, comprising: at least one processor; and at least one memory including computer program code; the at least one memory and the computer program code configured to, with the at least one processor, cause the apparatus at least to: receive resource configuration from at least one of a parent node or donor node, said resource configuration comprising information defining at least one resource type for a plurality of links for at least one time and at least one resource; and allocate, in dependence on said resource configuration, said at least one resource type for said at least one time to at least one link of said plurality of links, said at least one link being with one or more child nodes. ### Claim 27 (depends on 26) The apparatus as claimed in claim 26, wherein the at least one memory and the computer program code are further configured to cause the apparatus at least to: determine one or more schedulable resources for at least one link of the plurality of links for the at least one time and the at least one resource based on said received resource configuration, said allocating using said determined schedulable resources. ### Claim 28 (depends on 26) The apparatus as claimed in claim 26, wherein said at least one resource comprises at least one physical resource block. ### Claim 29 (depends on 26) The apparatus as claimed in claim 26, wherein at least one resource type is flexibly allocable to any one of a plurality of said links. ### Claim 30 (depends on 26) The apparatus as claimed in claim 26, wherein said plurality of links comprises one or more of an uplink backhaul link with a first child node, a downlink backhaul link with said first child node, an uplink access link with a second child node and a downlink access link with a second child node. ### Claim 31 (depends on 30) The apparatus as claimed in claim 30, wherein at least one resource type defines for at least one time and at least one resource an access link with said second child node and a backhaul link with a first child node. ### Claim 32 (depends on 30) The apparatus as claimed in claim 30, wherein one or more of the following resource types is defined by said information in said resource configuration: a first type for the downlink child access link with the second child node and the downlink backhaul link with the first child node; a second type for the uplink child access link with the second child node and the uplink backhaul link with the first child node; and a third, flexible, type which can be used for any the links with first and second child nodes. ### Claim 33 (depends on 26) The apparatus as claimed in claim 26, wherein the at least one memory and the computer program code are further configured to cause the apparatus at least to: drop allocation of the at least one time and at least one resource to a link with said parent node and using said at least one time and at least one resource for at least one link with at least one child node. ### Claim 34 (depends on 26) The apparatus as claimed in claim 26, wherein at least one resource type is such that at least one time and at least one resource is not schedulable for a child link and is schedulable for a link with said parent node. ### Claim 35 (depends on 26) The apparatus as claimed in claim 26, wherein one or more of the following resource types is defined by said information in said resource configuration: a first parent node link type for the downlink backhaul link with the parent node; a second parent node link type for the uplink backhaul link with the parent node; and a third, flexible, parent node link type which can be used for any the links with the parent node and the child nodes. ### Claim 36 (depends on 35) The apparatus as claimed in claim 35, wherein the at least one memory and the computer program code are further configured to cause the apparatus at least to: receive further configuration information indicating that the third, flexible, parent node link type resource is reserved for a link with said parent node, determining that at least one time and at least one resource is not allocable to any one of a plurality of said child links and operating according to the further configuration information with said parent node. ### Claim 37 (depends on 26) The apparatus as claimed in claim 26, wherein at least one parent node link is time multiplexed with respect to at least one child link. ### Claim 38 (depends on 26) The apparatus as claimed in claim 26, wherein at least one parent node link and at least one child link are at least one of frequency division multiplexed or spatial division multiplexed with respect to one another. ### Claim 39 (depends on 38) The apparatus as claimed in claim 38, wherein the at least one memory and the computer program code are further configured to cause the apparatus at least to: receive further configuration information indicating that the third, flexible, parent node link type resource is reserved for a link with said parent node, and determine that at least one time and at least one resource is allocable to downlink child links if said at least one time and at least one resource is reserved for uplink parent node backhaul, or determine that at least one time and at least one resource is allocable to uplink child links if said at least one time and at least one resource is reserved for downlink parent node backhaul. ### Claim 40 (depends on 26) The apparatus as claimed in claim 26, wherein the resource type comprises one or more resource types for a plurality of links where at least one link is with the parent node and at least one link is with a child node. ### Claim 41 (depends on 26) The apparatus as claimed in claim 26, wherein said at least one time comprises a plurality of time slots, said resource type being one or more of slot specific and symbol specific. ### Claim 42 (depends on 26) The apparatus as claimed in claim 26, wherein said resource configuration is provided by at least one of the following: cell-specific higher layer configuration; dedicated higher layer configuration; or group-common physical downlink control channel. ### Claim 43 An apparatus, comprising: at least one processor; and at least one memory including computer program code; the at least one memory and the computer program code configured to, with the at least one processor, cause the apparatus at least to: cause resource configuration to be transmitted from a parent node or donor node, said resource configuration comprising information defining at least one resource type for a plurality of links for at least one time and at least one resource. ### Claim 44 (depends on 44) The apparatus as claimed in claim 44, the resource configuration being transmitted from the parent node or donor node to at least one integrated access and backhaul node. ### Claim 45 A method, comprising: receiving resource configuration from at least one of a parent node or donor node, said resource configuration comprising information defining at least one resource type for a plurality of links for at least one time and at least one resource; and allocating, in dependence on said resource configuration, said at least one resource type for said at least one time to at least one link of said plurality of links, said at least one link being with one or more child nodes.
