Engineering Contradiction Analysis
1Reliability
If data forwarding operation is continuously activated in collaborative UE, then MIMO performance is improved, but power consumption increases
Solution Approach 1:
The patent implements periodic activation and deactivation of data forwarding operation in collaborative UE based on uplink transmission requirements. The network node sends indication signals to activate or deactivate the forwarding operation at specific time intervals, allowing the collaborative UE to maintain MIMO performance only when needed while conserving power during periods when forwarding is not required.
2Reliability
If data forwarding operation is activated in collaborative UE, then effective number of MIMO layers is increased, but unwanted interference is generated
Solution Approach 1:
The network node monitors the data forwarding operation and sends indication signals to the collaborative UE to activate or deactivate forwarding based on network conditions. This feedback mechanism allows the system to dynamically adjust the forwarding operation to maximize MIMO capability while minimizing interference generation by deactivating forwarding when it would cause harmful effects.

AI summary
Methods and apparatus pertaining to on-off control of data forwarding operations in mobile communications are described. An apparatus transmits at least one configuration parameter to a collaborative device. The configuration parameter is transmitted to the collaborative device to determine a time to activate a data forwarding operation of the collaborative device. The apparatus further transmits a first RF signal in a first frequency band to a network node according to the configuration parameter and transmits a second RF signal in a second frequency band to the collaborative device in an event that the data forwarding operation of the collaborative device is activated. The first RF signal and the second RF signal carry uplink data to be transmitted to the network node, and the first frequency band is different from the second frequency band.
