PUCCH-Based Uplink Resource Allocation for PUSCH Data Sizing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems allocate uplink resources without considering the size of uplink data to be transmitted, leading to increased transmission time or resource wastage, as they rely on scheduling request messages without providing information on data size.
Innovation Solution
The electronic device determines transmission power and resource allocation based on the size of uplink data, using physical uplink control channel (PUCCH) resources to identify and allocate appropriate physical uplink shared channel (PUSCH) resources accordingly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If uplink resources having a relatively small size are allocated, then resource wastage is reduced, but transmission time increases and additional messages are required
Solution Approach 1:
The patent changes the parameter of resource allocation size based on the reception intensity of the scheduling request message. By measuring the reception intensity (signal strength) of the SR message, the network can dynamically adjust the allocated uplink resource size to match the actual data transmission needs, thereby avoiding both resource wastage and excessive transmission time
Solution Approach 2:
The patent introduces a feedback mechanism where the network measures the reception intensity of the scheduling request message and uses this feedback information to determine the appropriate resource allocation size. This feedback loop enables adaptive resource allocation that responds to actual channel conditions and data size requirements
2Loss of time
If uplink resources having a relatively large size are allocated, then transmission time is reduced, but resource wastage increases
Solution Approach 1:
The patent dynamically changes the resource allocation parameter based on reception intensity measurements. When reception intensity is high, smaller resource sizes are allocated; when reception intensity is low, larger resource sizes are allocated. This parameter adaptation resolves the contradiction between transmission time and resource wastage
Solution Approach 2:
The patent makes the resource allocation dynamic rather than static. The allocation size is adjusted in real-time based on the measured reception intensity of scheduling request messages, allowing the system to adapt to varying data sizes and channel conditions, thereby optimizing both transmission time and resource utilization
3Device complexity
If predetermined size uplink resources are allocated without identifying data size, then allocation process is simplified, but transmission efficiency decreases
Solution Approach 1:
The patent replaces the manual or complex method of data size estimation with an automated signal-based measurement system. By using reception intensity measurement of the scheduling request message as a proxy for data size indication, the system automatically determines appropriate resource allocation without requiring complex data size reporting mechanisms from the UE

AI summary
According to various embodiments, a method of operating a network may include: identifying a scheduling request message from an electronic device through at least one first resource, and the at least one first resource may include at least a portion of physical uplink control channel (PUCCH) resources allocated to the electronic device; identifying a reception intensity of the scheduling request message in the at least one first resource; identifying at least one second resource allocated to the electronic device, based on the reception intensity, wherein the at least one second resource may be allocated for a PUSCH of the electronic; and transmitting downlink control information (DCI) including information for identifying the at least one second resource to the electronic device.
