Abstract: The present invention describes how to handle errors occurring during communication in a frame-based communication system that uses a communication protocol having a first error handling mechanism responsive to receipt of an incorrect protocol symbol. The invention provides a method and apparatus that allow several errors to occur without the communication system responding by initiating the first error handling mechanisms. Under circumstances where errors occur, the method and apparatus may improve throughput.

Abstract: Methods, systems, and devices for wireless communication are described. A base station may transmit a configuration for enhanced paging to a UE being served by a cell over a shared frequency band. The enhanced paging may include multiple paging intervals for each paging cycle. The UE may enable reception for a paging interval and determine whether the UE receives a downlink transmission. The UE may lengthen a paging interval or enable reception during a second paging interval based in part on determining whether the UE receives a downlink transmission. In some examples, the UE may receive a paging queue status indication indicating that paging information will be transmitted during a paging interval or a later interval, or indicating that no paging information is present at a serving cell.

Abstract: Methods, systems, and devices for wireless communication are described. A user equipment (UE) may monitor a neighbor cell and report the result to a serving base station. Based on the report, the serving base station may identify an estimated discovery reference signal (DRS) transmission window of the neighbor cell. In some cases, the UE may estimate and report parameters of the neighbor DRS transmission window, and in other cases, the UE may make a measurement report and the base station may infer DRS transmission window parameters. The base station may then provide the UE with a DRS measurement timing configuration (DMTC) based on the estimated parameters of the neighbor cell so that the UE may monitor the neighbor cell and the serving cell in an efficient manner. For example, the UE may conserve battery life by refraining from monitoring DRS during periods when a DRS transmission is not likely.

Abstract: Methods and apparatuses are provided for causing active hand-in of a device from a macrocell base station to a femto node, which can be an inter-frequency hand-in. The femto node can broadcast a beacon, which can be received and reported by a device to a source base station along with one or more parameters. The source base station can communicate a handover message to the femto node or a related femto gateway along with the one or more parameters. The femto node or femto gateway can disambiguate the intended target femto node based in part on the one or more parameters, which can include applying one or more filters. Applying the one or more filters may include applying an UL RSSI filter to the one or more femto nodes to determine whether presence of the device causes a rise in UL RSSI measured at the one or more femto nodes.

Abstract: A system and method for minimizing power consumption in a transceiver circuit that uses a digital high-speed serial communications link between at least two devices is presented. Comma code matching is generally used as a means for establishing byte synchronization and for determining and preventing data transfer errors. However, comma code matching, when performed in high speed serial communications links that can transfer data at rate of giga-bits per second, can use a significant amount of power. Thus, the system and method described herein maintain comma code matching in an off-state, and transition comma code matching from an off-state to an on-state when a substantive operational change occurs in the serial communications link.

Abstract: Systems and methods for handling a loss of message boundary in a real-time data transmission over an interconnect between a source node and a destination node are described. The destination node receives messages including one or more data frames. Each data frame includes an end-of-message flag, which is set when the data frame is last frame of a message, and a message sequence number, which is different for different messages. The destination node determines a loss of message boundary when a new data frame has a message sequence number different from the message sequence number of a previously received message, which did not have the end-of-message flag set. The destination node then transmits a synchronization loss message to the source node, and receives, as response, a status report message. The destination node is able to regain synchronization by determining a lost message boundary according to the status report message.

Abstract: Methods and devices for testing a physical layer (PHY) of an asymmetrical interconnect interface using a traffic generator/analyzer (TGA) are described. At least one special PHY test sequence is transmitted to the asymmetrical interconnect interface during link start up to place the device under test in PHY testing mode in which the TGA is used to generate and analyze data. The asymmetrical interconnect interface can then receive a configuration command and configure the asymmetrical interconnect interface in response to the configuration command. The asymmetrical interconnect interface can then use the TGA to transmit test sequences to, or receive test sequences from, e.g., a tester, on at least one identified lane of the asymmetrical interconnect device, which at least one identified lane is set by the configuration command.

Abstract: An electronic device is provided which comprises a plurality of processing units (IP1-IP6), a network-based interconnect (N) coupled to the processing units (IP1-IP6) and at least one monitoring unit (P1, P2) for monitoring a data flow of at least one first communication path between the processing units (IP1-IP6) and for forwarding monitoring results at least temporarily via at least two separate communication paths (MC1, MC2).

Abstract: A method for ensuring guaranteed services for real-time traffic on an interconnect with errors is provided. The real-time traffic comprises a first and second traffic class (HRT, SRT). Real-time traffic of the first and/or second traffic class (HRT, SRT) is transmitted from a transmitter to a receiver. It is detected by the receiver whether an error has occurred during the transmission of the real-time traffic and the error is reported to the transmitter. At least part of the real-time traffic of the second traffic class (SRT) is re-transmitted by the transmitter if the transmitter has received an error report from the receiver within a predetermined time period.

Abstract: A system and method are described for correcting for a loss of message boundary in a real-time data transmission over an interconnect between a source node and a destination node in an apparatus. In the apparatus, a destination node received one or more messages, wherein each message includes one or more data frames, and each data frame of each message includes an end-of-message flag and a message sequence number, the end-of-message flag set when the data frame is the last data frame in a particular message, and the message sequence number is different for different messages. A loss of message boundary is determined for a previous message when a new data frame of a new message is received and the new message sequence number of the new data frame is different from the previous message sequence number and a last received data frame did not include a set end-of-message flag.

Abstract: Link startup systems, methods and devices associated with interconnects are described. Asymmetric lane connections are supported by, for example, independent renumbering of the connected lanes after an initial discovery process. Low-power, hibernating states of devices are supported by, for example, initialing alternating between transmission of startup and wakeup sequences over the interconnect between devices.

Abstract: A method for transmitting data is described that includes the steps of: Producing a data frame for transmission, the data frame including a sequence number and user data, saving a copy of the data frame in a retransmission buffer, and if said step of saving a copy requires that data already present in the retransmission buffer is overwritten, selecting the one or more oldest data frames in the retransmission buffer to be overwritten, in case an error is determined in the received data frame, communicating an error message to the transmitter of the data frame, which error message at least comprises an indication of the sequence number of the last correctly received data frame,—upon receipt of such message and if available, retransmitting one or more data frames from the retransmission buffer having a sequence number higher than the sequence number communicated in the message.

Abstract: Disclosed are methods, and control devices (110, 210, 310) having programmable processors configured to implement methods, of communicating with a network (100, 300) having an initially unknown topology and a plurality of unknown devices. The methods use set and get configuration commands to discover the unknown devices on the network using one or more host ports of the control device, enumerating the discovered devices by using the one or more host ports to assign a different network address to each discovered device, so that the enumerated devices correspond to the network topology.

Abstract: A cut-through data packet mechanism is described. Forwarding of a cut-through data packet by an intermediary node enables packet transmission of the cut-through data packet to begin prior to performing a frame CRC on the packet. The CRC is instead performed while transmission of the packet is occurring. If one or more errors are found in the cut-through data packet, then a packet trailer indicating such errors is transmitted toward an endpoint node that receives the cut-through packet.
