Base Station Processing Device Uplink Transmission Cycle Determination
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In radio communication systems, uplink communication from a terminal to a base station often experiences delays due to the need for resource allocation requests, which can be inefficient, especially when the timing of data transmission does not align with the predetermined allocation cycles.
Innovation Solution
A processing device within the base station determines the transmission cycle of incoming data based on received timing and candidates, and inserts or modifies data to include scheduling requests, allowing for proactive allocation of communication resources, thereby reducing delays by synchronizing data generation and resource allocation.

Engineering Contradiction Analysis
1Loss of time
If the terminal waits for predetermined allocation cycles to request communication resources, then the base station can manage resource allocation systematically, but communication delays occur when data transmission timing does not align with allocation cycles
Solution Approach 1:
The base station proactively determines the transmission cycle of uplink data and requests allocation of communication resources in advance, before the terminal actually needs to transmit. This preliminary action eliminates waiting time for resource allocation and prevents communication delays caused by misalignment between data generation and resource allocation cycles.
Solution Approach 2:
The base station monitors the transmission timing of uplink data from the terminal and uses this feedback to dynamically adjust and determine the optimal transmission cycle. This feedback mechanism enables the system to adapt resource allocation timing to actual data transmission patterns, reducing delays while maintaining efficient resource management.
2Productivity
If the terminal requests communication resources frequently to ensure timely data transmission, then communication delays are reduced, but resource allocation overhead and system complexity increase
Solution Approach 1:
Instead of frequent reactive requests from the terminal, the base station performs a single preliminary determination of the transmission cycle and requests resource allocation in advance. This approach achieves high transmission efficiency by ensuring resources are ready when needed, while avoiding the overhead of frequent allocation requests.
Solution Approach 2:
The base station changes the parameter of resource allocation from frequent small-time-step allocations to less frequent but larger-time-step allocations based on the determined transmission cycle. This parameter change reduces allocation overhead while maintaining the ability to respond timely to data transmission needs.

AI summary
According to one embodiment, a processing device for a base station including a first layer and a second layer, includes a receiver unit configured to receive first data from the first layer, a processing unit configured to generate second data based on the first data, and a transmitter unit configured to transmit the second data to the second layer. The processing unit is configured to determine a transmission cycle of the first data based on a timing at which the first data is received and a plurality of transmission cycle candidates, and cause the transmitter unit to transmit the second data at a timing based on the transmission cycle of the first data.
