Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The traditional LTE system's static or semi-static resource configuration fails to dynamically match the varying data volumes in uplink transmissions, leading to resource wastage and transmission delays.
Innovation Solution
User equipment determines the size of time-frequency resource blocks based on actual data volume, allowing dynamic allocation of resources and optimizing transmission power and modulation schemes for reliable communication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If static or semi-static resource configuration is used, then resource allocation is simple and reliable, but it cannot dynamically match varying data volumes leading to resource wastage and transmission delays
Solution Approach 1:
The patent applies dynamics by enabling the user equipment to dynamically determine the size of the first time-frequency resource block based on the actual data volume to be transmitted. Instead of using static or semi-static resource configuration, the system allows adaptive resource selection where the resource block size varies according to the data volume, thereby resolving the contradiction between adaptability and complexity through user equipment autonomy in resource determination.
2Productivity
If fixed resource allocation is used for all data volumes, then resource allocation is simple, but it causes resource wastage when data volume is low and transmission delays when data volume is high
Solution Approach 1:
The patent applies parameter changes by allowing the resource block size to vary based on the data volume parameter. The user equipment determines the appropriate size of the first time-frequency resource block according to the actual data volume, enabling the system to adjust resource allocation parameters dynamically. This resolves the contradiction by improving resource utilization efficiency for small data volumes while avoiding transmission delays for large data volumes through parameter adaptation.
3Reliability
If larger resource blocks are allocated to ensure sufficient capacity, then transmission reliability is maintained, but resource wastage increases when data volume is low
Solution Approach 1:
The patent applies self-service by enabling the user equipment to autonomously determine the appropriate resource block size based on its own data volume requirements. The user equipment independently decides whether to use a first time-frequency resource block with or without the second time-frequency resource sub-block, eliminating the need for network-side resource allocation decisions. This self-service mechanism ensures transmission reliability by allocating sufficient resources when needed while avoiding resource wastage by preventing over-allocation when data volume is low.

AI summary
The present disclosure discloses a method and a device for wireless communication in UE and base station. The user equipment determines a first time-frequency resource block by itself on a first sub-band and transmits a first wireless signal in the first time-frequency resource block on the first sub-band. Wherein, the first wireless signal carries a first bit block and a second bit block; the first time-frequency resource block comprises a first time-frequency resource sub-block, and whether the first time-frequency resource block comprises a second time-frequency resource sub-block is related to the number of bits included in the first bit block; the second bit block is used to determine the first time-frequency resource block; The above method allows the UE to dynamically select the size of the occupied uplink wireless resource according to the size of the actual data amount, while avoiding the resource waste and the extra transmission time delay.
