Transmission Resource Pool Configuration for Load Balancing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In communications systems, the orthogonal nature of centralized and distributed transmission resource pools leads to unbalanced loads, resulting in low transmission resource utilization, as these pools cannot be interchangeably used for different transmission modes.
Innovation Solution
A method where a terminal receives configuration information about transmission resource pools from a network device, allowing it to determine the state of the pool and independently select resources for direct link transmission, thereby using the pool as either a distributed or centralized resource pool based on availability and demand.

1Reliability
If orthogonal resource pools are used for centralized and distributed transmission modes, then transmission modes can be clearly distinguished, but transmission resource utilization becomes low due to load imbalance
Solution Approach 1:
The patent makes the transmission resource pool universal by enabling it to serve both centralized and distributed transmission modes. The network device configures the resource pool with parameters that allow terminals to perform both centralized transmission (with network scheduling) and distributed transmission (with autonomous resource selection) using the same pool, thereby eliminating the need for separate orthogonal pools and improving overall resource utilization.
Solution Approach 2:
The patent introduces dynamic configurability to the transmission resource pool through network device control. The network device can dynamically adjust pool parameters, activate or deactivate specific resources within the pool, and modify pool characteristics based on current network conditions and traffic demands. This dynamic nature allows the same resource pool to adapt to different transmission modes and load conditions, resolving the static limitation of orthogonal pools.
2Ease of operation
If separate resource pools are allocated for centralized and distributed transmission, then load balancing can be controlled, but resource waste occurs when one pool is underutilized
Solution Approach 1:
The patent implements a feedback mechanism where the network device monitors the utilization status of the transmission resource pool and dynamically adjusts configurations based on this feedback. When distributed transmission resources are underutilized, the network device can reconfigure the pool to accommodate more centralized transmission opportunities, and vice versa. This feedback-driven dynamic adjustment prevents resource waste while maintaining operational control.
Solution Approach 2:
The patent utilizes parameter changes within the transmission resource pool configuration to achieve load balancing without requiring separate pools. The network device modifies parameters such as resource availability indicators, transmission mode flags, and pool capacity settings based on current network conditions. These parameter adjustments allow the same physical resources to be dynamically allocated between centralized and distributed modes, eliminating resource waste while maintaining load control.

AI summary
Embodiments of the present invention provide a transmission resource configuration method, an apparatus, and a system, and relate to the field of communications technologies, to improve transmission resource utilization. The method includes: receiving, by a terminal, at least one piece of first transmission resource pool configuration information sent by a network device, where the first transmission resource pool configuration information includes at least a first transmission resource pool identifier and first transmission resource pool resource configuration information; when the terminal determines that a first transmission resource pool corresponding to the first transmission resource pool identifier is in a first state, independently selecting, by the terminal, a direct link transmission resource from time-frequency transmission resources corresponding to the first transmission resource pool resource configuration information; and sending, by the terminal, direct link service data by using the direct link transmission resource.
