When web requests fail intermittently, repeated fetches switch between direct access and proxy paths in different countries to recover content delivery.

When uplink buffers are empty, this case shows how generating a new transport block alongside MIMO retransmission preserves spatial multiplexing throughput.

Pre-assigned PUCCH resources let terminals send mixed-priority HARQ-ACKs in one uplink control channel with lower delay and overhead.
