Configuration for in-X subnetworks

A first device in a first network, comprising:

• at least one processor;
• and
• at least one memory including computer program codes;
• the at least one memory and the computer program codes are configured to, with the at least one processor, cause the first device at least to:
• obtain, from a third device in a second network, resource configuration supporting communication between the first device and a second device in the first network, the communication comprising more than one traffic type,
• wherein a first traffic type of the more than one traffic type is for data transmission between the first device and the second device without involving the third device, and a second traffic type of the more than one traffic type is for data transmission between the second device and the third device via the first device;
• determine, based at least on the resource configuration and the more than one traffic type, at least one resource pool to be used for the communication between the first device and the second device;
• and
• transmit, to the second device, information indicative of the at least one resource pool;
• wherein the resource configuration indicates at least one of:
• a first carrier part comprising one or more resource pools available for the first traffic type;
• and
• a second carrier part comprising one or more resource pools available for at least one of the first traffic type and the second traffic type;
• and
• wherein the first device is caused to determine the at least one resource pool by:
• determining the at least one resource pool from the one or more resource pools comprised in the second carrier part for one of:
• the first traffic type, if the first device is located out of a coverage of the second network or there is no data transmission of the second traffic type between the third device and the second device within a time period;
• and
• the second traffic type, if the first device is located within the coverage of the second network and there is data transmission of the second traffic type between the third device and the second device within the time period.
