TRP Network Operation Sequences for Power and Traffic Trade-offs
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication systems face challenges in reducing network power consumption while managing traffic loads, as network entities like base stations in 5G systems consume significant power and existing network operation sequences offer limited flexibility in balancing energy savings with data rates.
Innovation Solution
Implementing separate network operation sequences for different transmission and reception points (TRPs), allowing them to operate in lower-power modes while accommodating dynamic network traffic, with TRPs configured with distinct parameters or restrictions, and associated with different control resource sets or virtual component carriers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If network entities operate in high-power modes to accommodate dynamic network traffic, then network traffic management capability is improved, but power consumption increases
Solution Approach 1:
The patent divides the network into multiple Transmission Reception Points (TRPs), each capable of operating independently with its own network operation sequence. This segmentation allows individual TRPs to be placed in different operation modes (full functionality, reduced functionality, or dormant) based on local traffic conditions, thereby reducing overall network power consumption while maintaining traffic management capability where needed.
Solution Approach 2:
The patent implements dynamic network operation sequences that allow TRPs to transition between different operation modes based on real-time traffic conditions. Each TRP can dynamically adjust its functionality level (full, reduced, or dormant) and associated parameters (bandwidth, power, antenna elements) to match current traffic demands, optimizing the balance between power consumption and traffic management capability.
2Use of energy by stationary object
If network entities reduce power consumption to save energy, then power consumption is reduced, but network traffic accommodation capability deteriorates
Solution Approach 1:
The patent implements periodic network operation sequences where TRPs alternate between different operation modes according to predefined time intervals or traffic patterns. During periods of low traffic, TRPs can enter reduced functionality or dormant modes to save power. During high-traffic periods, they transition back to full functionality modes, thereby accommodating traffic demands while reducing overall power consumption through periodic operation cycles.
Solution Approach 2:
The patent changes operational parameters (bandwidth, power levels, antenna elements, resource blocks) of TRPs based on their operation mode. When transitioning to reduced functionality or dormant modes, parameters are adjusted to lower power consumption levels. When traffic demands increase, parameters are restored or increased to accommodate higher data rates and traffic loads, thus balancing power savings with traffic accommodation capability.
3Use of energy by stationary object
If separate network operation sequences are implemented for multiple TRPs, then power consumption is reduced through selective mode operation, but system complexity increases
Solution Approach 1:
The patent implements a universal framework for network operation sequences that can be applied to multiple TRPs with different capabilities and traffic conditions. The same basic sequence structure (full functionality, reduced functionality, dormant modes) is used across all TRPs, but each TRP can be configured with specific parameters and time intervals suited to its role. This universal approach reduces complexity compared to designing completely separate control mechanisms for each TRP while still enabling differentiated operation.
Solution Approach 2:
The patent introduces a central controller or coordinating entity that manages the network operation sequences for multiple TRPs. This intermediary handles the complexity of configuring and coordinating different TRP sequences, allowing individual TRPs to operate autonomously according to their sequences while the intermediary ensures overall network coherence and handles inter-TRP coordination, thereby distributing the system complexity rather than concentrating it at each TRP.
4Use of energy by stationary object
If some TRPs operate in lower-power modes, then overall network power consumption is reduced, but data rate capability for those TRPs decreases
Solution Approach 1:
The patent applies local quality by allowing different TRPs to operate in different functionality modes based on their local traffic conditions and importance. Critical TRPs handling high-data-rate traffic maintain full functionality modes, while less critical TRPs or those serving areas with lower traffic demands operate in reduced functionality or dormant modes. This localized differentiation optimizes the balance between power consumption and data rate capability at each TRP based on local requirements.
Solution Approach 2:
The patent merges the capabilities of multiple TRPs to provide overall network coverage and capacity. When some TRPs operate in lower-power modes with reduced data rate capability, other TRPs can compensate by handling additional traffic or providing enhanced service to specific users. The combined network capacity of multiple TRPs operating at different power levels maintains overall data rate performance while reducing total power consumption.

AI summary
Methods, systems, and devices for wireless communications are described. The described techniques are directed to transmission and reception point (TRP)-specific network operation sequences. A first TRP may be configured with a first network operation sequence, and a second TRP may be configured with a second network operation sequence. The use of separate network operation sequences for different TRPs may enable some TRPs to operate in lower-power consumption modes, while simultaneously enabling a network to accommodate dynamic network traffic. Different network operation sequences may be configured with different parameters or restrictions. Different TRPs may be associated with different control resource set (CORESET) indices or different virtual component carriers. In some examples, a first TRP may indicate parameters to a UE for communicating with a second TRP in a flexible mode at the second TRP.
