Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing communication systems face limitations in simultaneously scheduling more than four cells due to coding capacity constraints, leading to increased user equipment power consumption and reduced transmission efficiency.
Innovation Solution
A scheduling method that utilizes a combination of first and second signalings to schedule a plurality of physical channels or cells, allowing the total number of bits to exceed the coding capacity limits of a single signaling, thereby enabling simultaneous scheduling of more cells and improving efficiency.

Engineering Contradiction Analysis
1Productivity
If a single signaling is used to schedule multiple cells, then the coding capacity is constrained to 16 bits, but the number of simultaneously schedulable cells is limited to 4
Solution Approach 1:
The scheduling information is segmented into multiple independent signalings (first signaling and second signalings). The first signaling carries common scheduling information for multiple cells, while each second signaling carries cell-specific information. This segmentation allows the system to schedule more than 4 cells simultaneously by distributing the total information across multiple signaling messages, each within the 16-bit coding capacity constraint.
Solution Approach 2:
The patent transitions from a single-dimension scheduling approach (one signaling message) to a multi-dimensional approach (multiple signaling messages with different information types). By adding the dimension of multiple signalings with distinct roles (common vs. cell-specific information), the system overcomes the 16-bit limitation and enables scheduling of more cells without violating coding capacity constraints.
2Productivity
If multiple signalings are used to schedule more cells, then the number of schedulable cells increases, but the terminal device power consumption increases due to increased blind detections
Solution Approach 1:
The first signaling is transmitted before the second signalings and contains preliminary scheduling information including a first quantity parameter that indicates how many second signalings will follow. This preliminary action allows the terminal device to prepare for the expected number of subsequent signalings, reducing the need for extensive blind detections and thereby lowering power consumption.
Solution Approach 2:
The first signaling provides feedback information (the first quantity parameter) about the structure and number of subsequent second signalings. This feedback mechanism enables the terminal device to optimize its reception strategy by knowing in advance how many signalings to expect, reducing unnecessary blind detections and energy consumption.
3Reliability
If the first signaling contains information about the first quantity of second signalings, then the terminal device can reduce blind detections, but the first signaling requires more bits
Solution Approach 1:
The patent changes the parameter representation by using a compact encoding scheme for the first quantity parameter. Instead of using a full 16-bit field, the first quantity is encoded using fewer bits (e.g., 2-4 bits) since it represents a small integer value (0-15). This parameter change allows the first signaling to include quantity information while maintaining the total bit length within the 16-bit coding capacity constraint.
