Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If data is allocated over fixed resources, then resource allocation is simple, but data concentration occurs in certain areas reducing transmission efficiency
Solution Approach 1:
The patent implements dynamic resource allocation by allowing the base station to shift the position of resource blocks (RBs) within a narrowband data channel based on channel conditions and data distribution requirements. This dynamic adjustment prevents data concentration in certain frequency areas and optimizes transmission efficiency across different communication scenarios.
Solution Approach 2:
The patent changes the position parameter of resource blocks by introducing a shift amount that can be configured through higher layer signaling or implicitly derived from resource allocation information. This parameter change enables flexible RB repositioning to align with wideband RBG boundaries while maintaining system simplicity.
2Productivity
If resource blocks are shifted to align with wideband RBG boundaries, then resource utilization improves, but signaling complexity increases
Solution Approach 1:
The patent uses the narrowband data channel configuration as an intermediary to convey resource block positioning information. The shift amount is either directly configured through higher layer signaling associated with the narrowband configuration or implicitly determined from the resource allocation indication, avoiding the need for separate complex signaling messages.
Solution Approach 2:
The narrowband data channel configuration serves multiple functions: it defines the narrowband bandwidth, indicates the starting resource block, and conveys the shift amount for RB repositioning. This multi-functionality reduces overall signaling overhead while achieving precise resource block alignment with wideband RBG boundaries.
3Reliability
If precoding resource block groups are adjusted, then data transmission quality improves, but processing requirements increase
Solution Approach 1:
The patent dynamically adjusts the precoding resource block group (PRG) configuration based on the shifted resource block positions within the narrowband data channel. The base station determines the appropriate PRG size and mapping according to the configured narrowband parameters, enabling adaptive precoding that improves transmission quality without requiring complete reconfiguration of the entire precoding system.

AI summary
The present disclosure relates to methods and devices for flexible resource allocation. In one aspect, a base station can generate a narrowband data channel including a plurality of resource blocks (RBs). The base station may shift a position of the RBs of the narrowband data channel to align with a wideband resource block group (RBG) boundary. The base station can also adjust a precoding resource block group (PRG) for the narrowband data channel. Also, the base station can transmit the narrowband data channel to a User Equipment (UE) based on adjusting the PRG. In another aspect, the base station may align a beginning or last RB of the plurality of RBs with the wideband RBG boundary and/or align a beginning or last RB of the PRG with the wideband RBG boundary. In another aspect, the base station may transmit an indication to the UE indicating a flexible resource allocation.
