For example, certain embodiments may utilize a cell-common delay composed of FL and part of SL (until a cell-specific reference surface).

The function of time may be a combination of two functions representing the FL and SL. The function can may be broadcasted in a system information block (SIB) or transmitted directly to the UE through radio resource control (RRC) signaling when it becomes active, is handed over, and/or regularly updated.

Abstract: A packetization module receives messages in a plurality of streams. The packetization module also accesses requirements corresponding to the plurality of streams and information indicating capacities of a plurality of paths between a first endpoint and a second endpoint. The messages are redundantly transmitted from a subset of the plurality of streams over the plurality of paths. The subset is selected based on the requirements and the capacities. In some cases, a timer is initiated in response to the packetization module receiving one of the first messages. The packets are then transmitted in response to expiration of the timer or in response to the packets reaching the capacities of the plurality of paths. In some cases, the messages are stored in buffers that define congestion windows for the streams. A congestion controller modifies the sizes of the congestion windows based on acknowledgment feedback.
