Configuring an intelligent reflecting surface (irs)

A network node for configuring a set of configurable reflectors, wherein the set of configurable reflectors are provided by a set of one or more intelligent reflecting surface (IRSs), the network node-being configured to comprising:

• a storage unit;
• and
• processing circuitry coupled to the storage unit, wherein the network node is configured to perform a method comprising.
• determining a first set of one or more IRS configuration parameters, wherein the first set of IRS configuration parameters comprises at least one of:
• (a) a first link quality metric for a first link between a first communication device (CD), and an access network node, wherein the first link comprises a first channel between the first CD and the set of one or more IRSs and a second channel between the set of one or more IRSs and the access network node;
• (b) a first quality-of-service (QoS) requirement for the first CD;
• or (c) a transmission status for the first CD;
• and
• based on the first set of IRS configuration parameters, partitioning the set of configurable reflectors, wherein the partitioning comprises defining at least a first subset of the set of configurable reflectors and a second subset of the set of configurable reflectors;
• and
• after defining the first and second subsets, configuring the first subset of the configurable reflectors and configuring the second subset of the configurable reflectors.
