Waiting Line Conscious Scheduling for OFDMA Networks, using JSFRA Formulation

Spectrum efficiency has become extremely relevant as wireless networks evolve. Increasing transmitter antenna on receiver will be the most common ways of improving spectral efficiency. MIMO systems will always have the efficiency to significantly improve performance, but complexity of such systems has made developing viable transmission schemes difficult. Backlogged packets queuing at such a coordinating base station with downlink interference broadcast channel experience very least amount of delay within our suggested approach. Transmission scheduling is used in conjunction using Joint Space Frequency Resource Allocation that will reduce the the total number of backlogged data. The problem in JSFRA is indeed not convex. In SCA, different optimization strategies been used to make non-convex constraint problems. Each user with a specific frequency is assigned to the corresponding base station in consecutive convex approximation, whereas SCA is dependent on QWSRM. The calculation of a user's packet size in a queue is defined as QWSRM. If QWSRM exceeds the queue length, the user will be assigned to a different base station utilizing alternating optimization. Backlogged packets are transferred in FIFO order in the transmission scheduling algorithm, even though the packet with the smallest transmission size is sent first. The delay experienced by backlogged packets can be reduced and the packets are queued on base station by combining both strategies. Such benefits have a significant impact on multi-user OFDMA MIMO interference broadcast channels.
