Abstract: In a wireless communication environment, there may arise a timing misalignment for SRS-RSRP measurement. In order to address this issue, a UE may receive an uplink transmission from second UE containing the uplink transmission timing for the first UE. The UE may then set its measurement timing to be the same as the uplink transmission timing. The UE then carries out SRS-RSRP measurement according to the newly-set measurement timing.

Abstract: A method and system for providing robust streaming of data from a multi-core die is disclosed. The techniques include using a high bandwidth memory (HBM) device as retransmit buffers for large amounts of data to ensure robust communication in relatively high round trip-transmission time (RTT) transmission. Another technique is supporting two or more Ethernet ports between components to both transmit the same data packets on the two ports to insure robustness. Another technique is to use sequence numbers and send data packets from the different ports in a round robin fashion and reorder the packets upon receipt of an external device. Another technique is dynamically adding and removing paths for data packets between devices with multiple ports based on the quality of the path.

Abstract: Methods and systems are provided for performing lossy dropping and ECN marking in a flow-based network. The system can maintain state information of individual packet flows, which can be set up or released dynamically based on injected data. Each flow can be provided with a flow-specific input queue upon arriving at a switch. Packets of a respective flow are acknowledged after reaching the egress point of the network, and the acknowledgement packets are sent back to the ingress point of the flow along the same data path. As a result, each switch can obtain state information of each flow and perform per-flow packet dropping and ECN marking.

During operation, the system establishes a hierarchical accounting structure to determine utilizations of different elements of a buffer on the switch. The hierarchical accounting structure comprises one or more parent elements, and each parent element is associated with one or more child elements. The system determines a base utilization of a child element based on an amount of buffer space allocated to the child element and an amount of buffer space used by the child element, and determines an adaptive utilization of the child element based at least on the base utilization of the child element and a congestion state of a corresponding parent element. Determining the adaptive utilization of the child element comprises performing a table lookup operation.

Abstract: A communication system and an operation method thereof are provided. The transmitting device transmits the current data unit and the transmitted data verification information to the receiving device through the communication interface, and records the current data unit in an FIFO buffer. The receiving device counts the received data identification value by itself based on the current data unit received from the communication interface. The receiving device uses the received data identification value and the transmitted data verification information to check whether the current data unit received from the communication interface has errors. When the current data unit is in error, the receiving device returns an error flag to the transmitting device so that the transmitting device suspends the transmission of the new data unit, and transmits the buffered data unit recorded in the FIFO buffer to the receiving device through the communication interface.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive an indication of a resource configuration for a random access (RA) procedure. The resource configuration may identify multiple sets of transmission resources corresponding to multiple radio resource control (RRC) states. The UE may identify an RRC state and may determine a set of transmission resources and/or a transport format based on the indication of the resource configuration, the identified RRC state, and/or a UE identifier (UE ID). The UE may transmit a first RA procedure message (e.g., a msgA) using the determined transmission resources and/or transport format. The base station may receive the message and may identify the RRC state of the UE based on the first message and transmitted indication of the resource configuration. The base station may transmit a second RA procedure message (e.g., a msgB), which the UE may receive.

Abstract: Systems and methods are provided for measuring available bandwidth available in a black box network by determining a probing rate of packet transmissions between a sender and receiver.

Additional actions may be performed, like automatically rerouting packets and/or load balancing network traffic after the probing rate is determined.

Abstract: Techniques are disclosed for transmitting electronic messages subject to multiple rate limits. In some embodiments, a send-side rate limiter employs a sliding log or other rate limiting technique to determine whether requests to transmit messages comply with rate limits associated with those messages. When the transmission of a message does not comply with associated rate limits, a negative acknowledgment message is sent to a queuing system, causing the message to be reinserted into a queue for later transmission. In addition, delivery rate limits are established for each queue in the queuing system to throttle the delivery of messages to a send service that makes requests to transmit messages to the send-side rate limiter.

Abstract: Techniques described herein determine positioning of synchronization signal blocks. One or more implementations receive at least one synchronization signal in a synchronization signal block from a first network entity, and an indication from a second network entity. The indication from the second network entity can be used to determine synchronization signal block positioning, such as time location(s). In turn, various implementations communicate with the first network entity based, at least in part, on the determined synchronization signal block(s).

Abstract: Aspects relate to managing a device-to-device communication link via radio resource control (RRC) layer signaling. In an example operation, a first wireless communication device establishes a unicast link with a second wireless communication device over a device-to-device communication interface and determines that the unicast link is to be reconfigured with at least one updated parameter.

The first RRC message includes the at least one updated parameter. The first wireless communication device receives a link reconfiguration response from the second wireless communication device via a second RRC message over the communication interface based on the link reconfiguration request and determines whether to reconfigure the unicast link using the at least one updated parameter based on the received link reconfiguration response.

Abstract: In a Multiple-Input Multiple-Output (MIMO) system including a large number of antenna ports, a base station such as a Node B communicates a total number of antenna ports by communicating the number of antenna ports per Channel State Information Reference Signal (CSI-RS) configuration and one or more CSI-RS configurations. A User Equipment determines the number of antenna ports from the information communicated by the base station by determining the number of CSI-RS configurations sent by the base station and multiplying that number by the number of antenna ports per CSI-RS configuration indicated by the base station.

Abstract: A wireless transmit/receive unit (WTRU) is configured to transmit scheduling information over a first uplink channel, on a condition that the WTRU has an uplink scheduling grant to transmit uplink data. In response to a triggering condition, when the WTRU is not transmitting on the first uplink channel, the WTRU is configured to transmit a plurality of a same value over a second uplink channel. The second uplink channel is a control channel. The transmission of the plurality of the same value is based on having an insufficient uplink scheduling grant for the first uplink channel.

Abstract: A scheduler in a network device serves ports with data units from a plurality of queues. The scheduler implements a scheduling algorithm that is normally constrained to releasing data to a port no more frequently than at a default maximum service rate. However, when data units smaller than a certain size are at the heads of one or more data unit queues assigned to a port, the scheduler may temporarily increase the maximum service rate of that port. The increased service rate permits fuller realization of a port's maximum bandwidth when handling smaller data units. In some embodiments, increasing the service rate involves dequeuing more than one small data unit at a time, with the extra data units temporarily stored in a port FIFO. The scheduler adds a pseudo-port to its scheduling sequence to schedule release of data from the port FIFO, with otherwise minimal impact on the scheduling logic.

The first device processes the packet based on the first upper limit value of the first queue buffer, an occupation value of the first queue buffer, and a size of the packet.
