Shared segmented upload in mobile networks using coordinated multipoint

Upload User Collaboration in the Data Upload for LTE-Advanced Networks

“…7 shows that the non-cooperative algorithm and CoMP behaved in a similar manner when the UE was within 305 m from the cell center. In both methods, as the UEs distance from their serving eNBs increased, the file upload time increased as well.However, when the UEs got closer to the cell borders, CoMP allowed UEs to upload their data file in a less time compared to the non-cooperative upload time.…”

“…In this research, we present two advanced algorithms, called Shared Segmented Upload (SSU) and Upload User Collaboration (UUC), with the goal of uploading large files from the UEs to the mobile network in a distributed CoMP architecture. Besides these two methods, which have been patented during this Thesis [7][8], we defined a new method for the joint data recovery of the received Transport Blocks (TBs) at the different eNBs to increase the probability of this process and to reduce the number of the required retransmission by the UEs. This technique has also been patented [8].…”

“…The upload process initial steps are similar to those of the Shared Segmented Upload 47 (SSU) algorithm (with some modifications) [76]. This means that by using the UUC cut down the data file into pieces 48 communication channels), the helper UEs use the SSU algorithm to upload the pieces.…”

“…7 andFigure 4.8 show the UUC sequence diagrams when an owner UE or a helper UE uploads a piece respectively.…”

Simulation of Coordinated Multipoint Using Discrete Event Systems Specification

“…This way the users in the switched off cell will be served without the need of a power boost in any of the neighbouring cells. Tavanpour et al [38] focus on improving the upload rate for users. They propose an algorithm which builds on CoMP and breaks down the file into smaller pieces for uploading.…”
