Flowlet scheduler for multicore network processors
11683119 · 2023-06-20 · ·

Systems and methods of using a packet order work (POW) scheduler to assign packets to a set of scheduler queues for supplying packets to parallel processing units. A processing unit and the associated scheduler queue is dedicated to a specific flow until a queue-reallocation event, which may correspond to the associated scheduler queue being idle for at least a certain interval as indicated by its age counter, or the queue being the least recently used, when a new flow arrives. In this case, the scheduler queue and the associated processing unit may be reallocated to the new flow and disassociated with the previous flow. As a result, dynamic packet workload balancing can be advantageously achieved across the multiple processing paths.

Latency negotiation in a heterogeneous network of synchronized speakers

A method is provided that can be performed by an audio source for negotiating latency in an audio network. The audio source receives information regarding an audio processing latency associated with each of a set of two or more audio output devices connected to the audio network. The audio source determines, based at least on the received information, a maximum delay for outputting audio samples streamed by the audio source from the audio output devices in the set. The audio source determines, based on the maximum delay, timing for outputting the audio samples from the audio output devices in the set. The audio source then communicates the determined timing to the set of audio output devices for processing the audio samples in accordance with the timing.

USER EQUIPMENT OPERATING MODE CONTROL

A notification regarding a transition of a User Equipment (UE) from a standby operating mode to an active operating mode is exchanged between a UE and a network element in a communication network. The notification could be an uplink notification that is transmitted by the UE to the network element in response to an operating mode transition criterion for the UE being met at the UE, or a downlink notification that is transmitted by the network element to the UE in response to an operating mode transition criterion for the UE being met at the network element. The UE transitions from the standby operating mode to the active operating mode in response to the operating mode transition criterion being satisfied. The transmitter of the notification, which could be the UE or the network element, could also perform grant-free transmission of data without first receiving a response to the notification.

Systems and methods are directed to low cost and low power carrier frequency offset (CFO) estimation in a receiver. In-phase (I) and quadrature (Q) samples of a wireless signal are received by the receiver and a first phase and a second phase are extracted from the outputs of a first autocorrelator with a first time-lag and a second autocorrelator with a second time-lag. The extracted first and second phases are combined to generate an estimated CFO of high accuracy and wide estimation range.

Tagging Mechanism and Out-of Sequence Packet Delivery for QoS Enhancement

A tagging mechanism supporting different QoS categories for IP/Port services in a cellular radio network is proposed. Tags are used to differentiate different types of services and corresponding QoS requirements. At the sender side, the sender of the IP packets is able to distinguish different types of services by tagging one or multiple bits for finer QoS control. For downlink IP traffic, the tagging function can be done at the base station. For uplink IP traffic, the tagging function can be done at the UE. At the receiver side, the receiver delivers the IP packets using out-of-sequence delivery for delay sensitive packets. With tagging and out-of-sequence delivery, the delay sensitive packets can reduce CN latency and transmission latency.

Method and First Node for Handling a Feedback Procedure in a Radio Communication

A method and a first node (700) for handling a feedback procedure requiring transmission of feedback messages indicating either an acknowledgement, ACK, or a non-acknowledgement, NACK, of correct reception of data transmitted on a forward link in a radio communication with a second node (702) in a radio network. The first node (700) obtains (300) a latency requirement of the radio communication corresponding to the time from transmission of the data until the data becomes outdated. The first node (700) further applies (304) a first transmission mode employing said feedback procedure when the latency requirement is above a latency threshold, and applies (306) a second transmission mode omitting said feed back procedure when the latency requirement is below the latency threshold.
