Resource Block Control Data Multiplexing for 5G Overhead Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication systems face inefficiencies in transmitting control information, which contributes to overhead and is not adequately addressed in existing multiplexing techniques, particularly in 5G networks requiring greater bandwidth operations.
Innovation Solution
The method involves identifying a resource block (RB) for data transmission, including control information with parameters for demodulation, and multiplexing this information with data using techniques such as frequency division multiplexing (FDM), time division multiplexing (TDM), or a combination thereof, within the RB, allowing flexible user capacity scaling and bandwidth support.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If control information is transmitted separately from data in traditional wireless systems, then control information can be clearly identified and processed, but this approach increases overhead and reduces transmission efficiency
Solution Approach 1:
The patent merges control information and data into the same resource block for transmission. The base station multiplexes control information with data within the RB, allowing the receiver to obtain both control parameters and data in a single reception operation, thereby reducing overhead and improving transmission efficiency
Solution Approach 2:
The resource block is designed to serve multiple functions simultaneously - it can carry both control information (for demodulation parameters) and user data. This multi-functional approach eliminates the need for separate dedicated control channels, reducing overall system overhead
2Productivity
If control information is embedded within data resource blocks, then overhead is reduced and transmission efficiency improves, but the complexity of separating and processing control information from data increases
Solution Approach 1:
The patent segments the resource block into distinct control information portions and data portions through multiplexing. The receiver correspondingly segments the received signal by demultiplexing to separate control information from data, making processing manageable despite the integrated transmission
3Adaptability or versatility
If traditional multiplexing techniques are used for control information, then implementation is straightforward, but these techniques do not adequately support 5G bandwidth requirements and flexible resource allocation
Solution Approach 1:
The patent implements dynamic resource allocation where the amount and position of control information within the resource block can be flexibly adjusted based on channel conditions, traffic requirements, and bandwidth availability. This dynamic approach enables 5G networks to adapt to varying bandwidth requirements while maintaining efficient resource utilization

AI summary
Transmission of user equipment (UE) specific control information within a resource allocation including resource blocks allocated for downlink transmissions to the UE is disclosed. Common control information may be provided in a first transmission time interval (TTI)-level control region, and UE-specific control information, specific to a particular UE, may be provided along with data in allocated downlink resources to the UE. A base station may identify a resource block (RB) for transmission of data to a UE along with UE-specific control information to be included in the RB. The control information may include, for example, parameters for use by the receiver in demodulating the RB. The base station may multiplex the control information with the data within the RB and transmit the RB and control information.
