Patent number: 11489785Abstract: A network traffic manager receives, from an ingress port in a group of ingress ports, a cell of a packet destined for an egress port. Upon determining that a number of cells of the packet stored in a buffer queue meets a threshold value, the manager checks whether the group of ingress ports has been assigned a token for the queue. Upon determining that the group of ingress ports has been assigned the token, the manager determines that other cells of the packet are stored in the buffer, and accordingly stores the received cell in the buffer, and stores linking information for the received cell in a receive context for the packet. When all cells of the packet have been received, the manager copies linking information for the packet cells to the buffer queue or a copy generator queue, and releases the token from the group of ingress ports.Type: GrantFiled: July 30, 2020Date of Patent: November 1, 2022Assignee: Innovium, Inc.Inventors: William Brad Matthews, Puneet Agarwal, Bruce H.

Patent number: 11490382Abstract: Aspects of the present application provide for flexibility in configuring channel access occasions for uplink transmissions within a configured grant transmission resource duration. The uplink transmission may be transmitted in the physical uplink shared channel (PUSCH). The configured grant transmission resource duration includes multiple orthogonal frequency division multiplexed (OFDM) symbols. In some implementations, resources for uplink transmissions are allocated such that an integer number of equally sized mini-slots, each of which is considered a separate PUSCH, fit within the slot. This occurs when the number of OFDM symbols within the slot is evenly divisible by the number of OFDM symbols in the mini-slot. In some embodiments, not all of the mini-slots in the slot are equal in size. This occurs when the number of OFDM symbols within the slot is not evenly divisible by a particular mini-slot size.Type: GrantFiled: June 18, 2020Date of Patent: November 1, 2022Assignee: Huawei Technologies Co., Ltd.Inventor: Mohamed Adel Salem

Patent number: 11444879Abstract: Systems and techniques are disclosed to reduce workload on base stations in a mobile network when content delivery networks cache content inside the network. A user equipment sets a flag only with those packets on the uplink which include requests that should be routed to the cache server inside the mobile network. The base stations perform deep packet inspection of those packets where flags have been set and forward other packets on to the rest of the relevant backhaul of the mobile network. After deep packet inspection, the base stations either route the packet to the cache server via an established connection or propagate the flag in an extension header to another network node for routing to the cache server. The resulting content is returned to the UE with the source address of the originally intended destination instead of the cache server, rendering the process transparent to the end user.Type: GrantFiled: November 8, 2019Date of Patent: September 13, 2022Assignee: QUALCOMM IncorporatedInventors: Huichun Liu, Xipeng Zhu, Gavin Bernard Horn
