Resource selection for subnetworks

A first device in a radio access network, comprising:

• at least one processor;
• and
• at least one memory storing instructions that, when executed by the at least one processor, cause the first device at least to perform:
• obtaining status information associated with a first subnetwork of the radio access network wherein the status information is indicative of:
• a channel quality of the first subnetwork, an interference level sensed within the first subnetwork, and a mobility status associated with the first subnetwork;
• determining, whether the following criteria is met:
• the channel quality of the first subnetwork exceeds a first threshold and the interference level sensed within the first subnetwork is less than a second threshold, and
• the mobility status of the first subnetwork indicates a fast moving status;
• based on determining none of the criteria is met, determining a first mode as a resource selection mode and not a second mode;
• transmitting, to a second device in the first subnetwork, configuration information at least associated with the determined resource selection mode, wherein the configuration information comprises a first parameter associated with the first mode, the first parameter comprising:
• a duration of a first period associated with the first mode during which the first device selects the resource for communication within the first subnetwork, and
• a starting offset indicative of when the first period starts;
• determining, based at least on the status information, a sensing offset within the sensing window, the sensing offset indicating a starting time when channel sensing is performed within the sensing window;
• transmitting, to the second device, a first indication indicative of the sensing offset;
• transmitting, to the second device, measurement configuration information associated with an interference measurement performed within the first subnetwork;
• receiving, from the second device, a measurement report associated with the interference measurement, wherein the measurement report is indicative of:
• an interference from a subnetwork in which the first mode is determined as the resource selection mode, and an interference over a frequency subband, wherein the frequency subband is the resource for communications within a subnetwork and not used in a subnetwork in which the first mode is determined as the resource selection mode;
• selecting the resource for the communication within the first subnetwork based at least on the measurement report;
• and
• transmitting, to the second device, a second indication indicative of the selected resource.
