Abstract: Methods, apparatus and systems for de-correlating training pattern sequences for high-speed links and interconnects. The high-speed links and interconnects employs multiple lanes in each direction for transmitting and receiving data, and may be physically implemented via signal paths in an inter-plane board such as a backplane or mid-plane, or via a cable. During link training, a training pattern comprising a pseudo random bit sequence (PBRS) is sent over each lane. The PBRS for each lane is generated by a PBRS generator based on a PRBS polynomial that is unique to that lane. Since each lane employs a different PRBS polynomial, the training patterns between lanes are substantially de-correlated. Link negotiation may be performed between link endpoints to ensure that the PBRS polynomials used for all of the lanes in the high-speed link or interconnect are unique. Exemplary uses include Ethernet links, Infiniband links, and multi-lane serial interconnects.

Abstract: Multimedia application data formats often use data packets and may contain packetized hierarchical layers with a base layer (BL) and one or more enhancement layers (EL). Packets that comprise variable length coded data typically provide padding bits, which can be used for adding checksum information. The checksum information refers to both, the decoded base layer and decoded enhancement layer packet data, and is used for detecting synchronization loss between the layers. Though the packets provide different individual amounts of padding bits, this variable amount of bits per packet is sufficient for adding checksum information for synchronization related purposes. This allows e.g. out-of-sync detection even if the enhancement layer encoding provides no overhead information for synchronization, in particular no packet headers and no packet synchronization words.

The processed timing information is provided to the user via an interactive user interface that allows the user to view the timing information from an application layer perspective.

Abstract: For voice traffic over-the-air in LTE, persistent schedule (PS) or semi-persistent (SPS) scheduling would be the preferred method as they minimize signaling messages. In PS or SPS, resources are pre-allocated to the UE 402 at regular intervals (e.g., every 20 milliseconds). At each time slot, the UE will generally transmit an IMBE frames which are encoded in ISSI packet. In ISSI, other data streams are multiplexed with the IMBE frame and thus the packet size varies depending on its position within a super-frame. For PS or SPS, eNodeB must allocated sufficient resources to support the largest packet that. Therefore, there is spare capacity when the packet is not of the largest size. The exemplary embodiments specify ways to use spare capacity to transfer data.
