Wireless network access to wireless network slices over a common radio channel
A wireless communication network serves wireless user devices over a radio channel that is allocated into subchannels for wireless network slices. A wireless access node schedules resource blocks from the subchannels to the wireless user devices based on their wireless network slices. The wireless access node detects a subchannel has available resource blocks and other subchannels need the available resource blocks. The wireless access node schedules the available resource blocks to the wireless user devices that need the available resource blocks and that use a higher priority wireless network slice. The wireless access node wirelessly exchanges user data with the wireless user devices over the scheduled resource blocks and exchanges the user data with the wireless network slices. The wireless network slices exchanging at least some of the user data with external systems.
