Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the network device attempts to perform multiple users cooperative communication without acquiring MUCC capability identifiers, then the system complexity is reduced, but the reliability of MUCC communication deteriorates because the network device cannot select appropriate UEs based on their capabilities
Solution Approach 1:
The patent applies preliminary action by having UEs report their MUCC capability identifiers to the network device in advance, before actual MUCC communication is needed. This allows the network device to already have capability information available when MUCC operations are required, eliminating the need for real-time capability negotiation and improving reliability without adding operational complexity.
Solution Approach 2:
The patent introduces MUCC capability identifiers as an intermediary element that mediates between UE capabilities and network device selection logic. These identifiers serve as simplified representations of complex UE capabilities, allowing the network device to make selection decisions based on straightforward identifier matching rather than complex capability analysis, thus improving reliability while managing system complexity.
2Measurement precision
If the network device acquires and processes MUCC capability identifiers for all UEs, then the precision of UE selection is improved, but the loss of information increases due to the additional capability information that must be managed and transmitted
Solution Approach 1:
The patent applies the extraction principle by isolating only the essential MUCC capability identifiers from the complete UE capability set. Instead of managing and transmitting all UE capability information, the system extracts and reports only the specific identifiers relevant to MUCC operations, reducing information overhead while maintaining sufficient precision for UE selection.
Solution Approach 2:
The patent transforms complex UE capability descriptions into simplified parameter representations (MUCC capability identifiers). This parameter change converts detailed capability information into compact, manageable identifiers that can be efficiently transmitted and processed, reducing information loss while preserving the essential selection criteria.
3Productivity
If the system implements comprehensive MUCC capability reporting and selection mechanisms, then the productivity of MUCC operations is improved, but the device complexity increases due to the additional signaling and processing requirements
Solution Approach 1:
The patent applies preliminary action by completing capability reporting during initial UE registration or attachment procedures, before MUCC operations begin. This preliminary collection of capability identifiers ensures that when MUCC operations are needed, the network device already has the necessary information for rapid UE selection, improving productivity without adding complexity to the actual MUCC execution phase.
Solution Approach 2:
The patent implements self-service by having UEs automatically report their own MUCC capability identifiers to the network device without requiring manual configuration or complex network-side capability discovery procedures. This self-reporting mechanism simplifies the overall system complexity while ensuring accurate capability information is available for productive MUCC operations.

AI summary
Embodiments of the present invention disclose a method for multiple users cooperative communication. The method provided in the embodiments of the present invention includes: acquiring, by a core network node, information about MUCC capability identifiers of at least two UEs, where the MUCC capability identifiers are used to identify MUCC capabilities of the UEs; and sending, by the core network node, the information about the MUCC capability identifier of the at least two UEs to a radio access network node, to enable the radio access network node to select, according to the capability identifiers of the UEs, a UE having a supporting capability of the MUCC capability and a UE having a benefited capability of the MUCC capability, so that the UE having a supporting capability supports, in MUCC communication, a bearer of the UE having a benefited capability.
