Modem Packet Combination for RF Module Bus Efficiency
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing technologies face inefficiencies in transferring packets between a modem and an RF module in computing devices, leading to underutilization of bus bandwidth and increased latency.
Innovation Solution
A modem combines multiple packets into a single combined packet for transmission to an RF module via a bus, using address information to direct data units to specific memory locations, thereby optimizing bandwidth usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If multiple packets are transmitted individually from modem to RF module, then transmission simplicity is maintained, but bus bandwidth utilization is low and transmission time is increased
Solution Approach 1:
The modem combines multiple individual packets into a single combined packet for transmission over the bus to the RF module. This merging approach increases bus bandwidth utilization by reducing the number of separate transmission operations, directly addressing the low productivity caused by individual packet transmissions while managing complexity through systematic packet combination logic
2Loss of time
If packet combination is implemented to increase bandwidth usage, then transmission time is reduced, but packet processing complexity increases
Solution Approach 1:
The modem performs preliminary actions by combining multiple packets into a combined packet before transmission occurs. This advance preparation reduces the actual transmission time over the bus, as the combination is done in advance rather than during transmission, effectively trading some processing complexity for significant time reduction
3Productivity
If combined packets are transmitted without address information, then transmission bandwidth is optimized, but data placement accuracy in memory is compromised
Solution Approach 1:
The combined packet is segmented into multiple data units, each with associated address information indicating its destination memory location. This segmentation allows the system to maintain optimized bus bandwidth utilization through combined packet transmission while ensuring precise data placement in the RF module's memory by providing address information for each individual data unit

AI summary
This disclosure provides systems, methods, and devices for combined packet transfer from a modem to a radio frequency (RF) module. In a first aspect, a method of combined packet transfer includes receiving, by a modem coupled to a radio frequency (RF) module through a first bus, a plurality of packets for transmission to the RF module for storage in a memory of the RF module, combining, by the modem, two or more of the plurality of packets to generate a first combined packet, and transmitting, by the modem, the first combined packet to the RF module via the first bus for storage in the memory. Other aspects and features are also claimed and described.
