Decoupled Indication Granularity for Flexible Wireless Transmission
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In wireless communications networks, particularly in 5G and NR-based systems, there is a challenge in indicating the transmission structure of uplink/downlink data using the license-exempt frequency band, where existing methods are inflexible and not suitable for opportunistic data transmission, leading to inefficient resource occupation and data transmission adjustments.
Innovation Solution
A method and apparatus for indication information transmission that decouples the detection period of indication information from its indicated time range, using a finer granularity to support flexible data transmission on both license-exempt and licensed frequency bands, by sending configuration information and indication information with varying time units, allowing for faster resource occupation and dynamic adjustments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the detection period of indication information is coupled with the indicated time range, then the system structure is simpler, but the flexibility of data transmission is reduced
Solution Approach 1:
The patent segments the indication information transmission into two independent components: the detection period (first time granularity) and the indicated time range (second time granularity). The terminal device detects indication information at detection moments determined by the first granularity, while the indication information specifies transmission structures for time ranges determined by the second granularity. This segmentation allows independent optimization of detection frequency and indication coverage, resolving the contradiction between flexibility and complexity.
Solution Approach 2:
The patent introduces dynamic adjustment capabilities by allowing the detection period and indicated time range to have different granularities and be independently configured. The terminal device can dynamically adapt its detection strategy based on the first granularity while the network can flexibly indicate transmission structures for different time ranges using the second granularity, enabling the system to respond dynamically to varying transmission requirements without rigid coupling.
2Productivity
If a finer detection granularity is used for indication information, then resource occupation speed increases, but the detection complexity increases
Solution Approach 1:
The patent applies local quality by allowing different granularities for different aspects of the system. The first granularity (detection period) can be set to a finer value when fast resource occupation is needed, while the second granularity (indicated time range) can be adjusted independently based on the specific transmission scenario. This localized optimization of granularity allows the system to achieve high productivity where needed without uniformly increasing complexity across all operations.

AI summary
A device includes a processor and a non-transitory computer-readable storage medium coupled to the processor. The non-transitory computer-readable storage medium has programming instructions for being executed by the processor. The programming instructions, when executed by the processor, cause the device to receive configuration information sent by an access network side communications apparatus. The configuration information includes identification information of at least one cell. The device is also caused to detect first indication information sent by the access network side communications apparatus by using a length of a first time as a granularity. The first indication information indicates a transmission structure corresponding to one or more time units included in a second time of the at least one cell identified by the identification information. The length of the first time is different from a length of the second time.
