Abstract: A method of system information (SI) acquisition with reduced signaling overhead is proposed. To reduce SI broadcast overhead, the quantity of periodic SI broadcast and the frequency of on-demand SI acquisition need to be reduced. In order to reduce the quantity of periodic SI broadcasting, on-demand SI delivery is enabled. With on-demand SI delivery, signaling overhead is proportional to the frequency of SI acquisition. From the network side, the base stations proactively provide SI delivery options and delivers SI over unicast or scheduled broadcast. From the UE side, UE determines how to acquire SI, i.e., by listening to broadcast or by sending an on-demand request via existing procedures such as a random-access procedure over a random-access channel (RACH).

Abstract: Enhanced paging mechanisms are proposed for Machine Type Communication (MTC) devices in 3GPP networks. First, adaptive paging is proposed to adaptively allocate extra paging occasions for MTC devices with no extra procedure or power consumption on normal UEs. Second, group paging is proposed to simultaneously page a plurality of MTC devices with one paging. Group paging is controlled in different levels for optimized signaling and easier management. In one embodiment, group broadcasting and group release are used. Third, paging with response policy is proposed to pre-define or dynamically configure paging response policies for MTC devices.

Abstract: A method of adaptive transmission time interval (TTI) tuning based on TCP information is proposed. First, a procedure for TCP information delivery between eNB and TCP sender/TCP receiver is disclosed. The TCP information comprises TCP status, TCP congestion window (CWND) size, TCP round trip delay, TCP SS threshold, TCP index, and TCP event indication. Second, various methods for eNB to configure TTI with UE TCP information and/or buffer information are disclosed. A first method is saturation detection which includes buffer status based saturation detection and CWND based saturation detection. A second method is Greedy Buffer Clearing. A third method is TCP state based TTI selection method.
