Dynamic Beam MIMO Mode Selection for Base Station Processing Load
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication systems face challenges in efficiently managing the use of Beam MIMO Mode A due to exponential processing complexity at base stations, which limits the number of user equipment (UEs) that can utilize this mode, leading to suboptimal communication and potential system overload.
Innovation Solution
A method and apparatus for selectively controlling the MIMO mode of uplink communication between a network node and user equipment (UE), determining the capability and desirability of using Beam MIMO Mode A or Mode B based on the UE's capabilities and the base station's processing capacity, allowing for dynamic mode selection to maximize throughput while preventing processing overload.

Engineering Contradiction Analysis
1Productivity
If Beam MIMO Mode A is used for uplink communication, then data rate and communication performance are improved, but base station processing complexity increases exponentially
Solution Approach 1:
The patent changes the operational parameters of Beam MIMO by introducing two distinct modes (Mode A and Mode B) with different processing requirements. Mode A provides high data rates with full beam processing, while Mode B reduces processing complexity by using simplified beam handling. The base station dynamically selects between these modes based on current processing capacity and channel conditions, thereby adjusting the complexity parameter to match system capabilities while maintaining optimal data rates.
Solution Approach 2:
The patent implements dynamic mode selection where the base station can switch between Beam MIMO Mode A and Mode B based on real-time processing load and channel conditions. This dynamic adaptation allows the system to optimize the balance between data rate and processing complexity, enabling high performance when resources are available and preventing overload when processing capacity is limited.
2Productivity
If more UEs use Beam MIMO Mode A, then system throughput increases, but base station processing burden becomes unmanageable
Solution Approach 1:
The patent segments the UE population into different groups based on their Beam MIMO mode assignments. By dividing UEs into those operating in Mode A (high throughput, high complexity) and Mode B (lower throughput, low complexity), the base station can manage processing loads more effectively. This segmentation allows multiple UEs to be served simultaneously without overwhelming the base station, as not all UEs require the full processing power of Mode A.
Solution Approach 2:
The patent applies partial action by allowing only a subset of UEs to operate in full Beam MIMO Mode A rather than all UEs. This selective application of the high-performance mode ensures that the base station processing burden remains manageable while still achieving high system throughput through the combined contribution of Mode A and Mode B UEs.
3Device complexity
If Beam MIMO Mode B is used, then base station processing complexity is reduced, but communication throughput decreases
Solution Approach 1:
The patent changes the operational parameters by defining Mode B with simplified beam processing characteristics. In Mode B, the base station uses reduced processing complexity techniques while still maintaining viable communication throughput. This parameter change allows the system to operate in a lower complexity regime when necessary, trading some throughput for manageable processing loads.
Solution Approach 2:
The patent implements dynamic mode selection where the base station can switch between Mode A and Mode B based on real-time processing load and channel conditions. This dynamic adaptation allows the system to optimize the balance between data rate and processing complexity, enabling high performance when resources are available and preventing overload when processing capacity is limited.

AI summary
Systems and methods for selecting a communication mode in a wireless network (10) include a communication mode selection procedure that may be carried out by the respective devices in an automated manner to identify a mode for communication between an electronic device (14) and a network node (12). The selection may be between P-MIMO Mode A, P-MIMO Mode B, B-MIMO Mode A, or B-MIMO Mode B. Determining the desired mode for communication is based on the ability and/or desirability of the network node (12) to efficiently process a maximum threshold number of electronic devices using the P-Mimo Mode A or B-MIMO Mode A and, thereafter, granting MIMO Mode B communication access to any subsequent electronic devices joining the communication network. Communication mode selection may occur dynamically based on changing channel conditions caused by mobility of the electronic user equipment devices and what overlapping and/or non-overlapping beams are needed to be used.
