Explain Multiple Access Coding Scheme In Gprs?

1.	Explain Multiple Access Coding Scheme In Gprs?
Answer» MULTIPLE access scheme is used in GPRS based on the FDD and TDMA ONE PAIR of up-link and down-link frequency channels are assigned to a user during a session The Multiple Access Coding Scheme is combined with statistical multiplexing [packet MODE communication], that allows several uses to share the same frequency channel Down-link uses first-come first-served packet scheduling and up-link uses a scheme that is similar to reservation ALOHA. Slotted ALOHA is utilized for reservation inquiries in a contention phase, followed by transferring DATA by utilizing dynamic TDMA with first-come, first-served scheduling
