3P3B- The proposed trinary(三元) partitioned black-burst-based broadcast protocol

包含兩個主要機制

1. mini DIFS 於mac 層中

讓emergency message (EM)有較高的priority

2. trinary(三元) partitioning

designed to iteratively(反復) partition the communication range into small sectors

3.collision handle & data transmission

遞迴切割,每次都會選擇outer partition做傳送

如果outer中有人,inner 和 middle 就不用送了

在第三部份的collision的handle中

如果一直碰撞,則會讓全部人都stop,重新進入競爭中

*跟GPSR的差別是,應該是用在"EM"的訊息處理上

只針對EM做優先傳送~

QOS aware dynamic uplink-downlink reconfiguration algo in TD-LTE

依據PAD(packet average delay) , PDR(packet drop ratio) , system throughput

舊有方法:RBU(resource block utilization)

僅依據buffer狀態調整 UL-DL

新方法: QA (QOS aware)

buffer+QOS

RT/NRT

RT->  優先權較高

NRT->優先權較低

Improveing LTE/LTE-A UE power efficiency with extended DRX cycle

*DRX
