Abstract: In an embodiment, a source node assigns a first number to a probe data packet in a probe data flow in a sending sequence, where the first number is used to select a transmission path for the probe data packet. The source node sends the probe data packet in the probe data flow to a destination node at a first sending rate. Each time the source node receives a probe data packet backhauled by the destination node, the source node sends a service data packet in a service data flow, where the service data packet is assigned a second number corresponding to the probe data packet, and the second number is used to select a transmission path for the service data packet.

A first wireless communication device communicates, with a second wireless communication device, a reservation indicating a plurality of reserved resources for a plurality of sidelink communications.

Abstract: Systems and methods are provided for using a short data frame sent at a particular rate that can be used to probe a channel on which an access point is operating. The rate can be increased/decreased depending on whether or not transmission of the short data frame was successful or not. In this way, the highest possible rate (which can be impacted by any or all of the following factors: number of spatial streams, modulation and coding scheme, channel bandwidth, guard interval) can be selected to transmit data on the channel. In other words, a transmission rate can be selected dynamically and on a per-packet basis for a spatial reuse data frame that would follow the short data frame based on whether transmission of the short data frame was successful.

Abstract: Aspects presented herein may improve the efficiency and/or the performance of a beacon-echo procedure between sidelink UEs. In one aspect, an apparatus receives, from a base station, at least one of a beacon power level or an echo power level for a beacon-echo procedure. The apparatus transmits, to a second UE, a beacon RS based on the beacon power level. The apparatus receives, from the second UE, an echo RS based on the beacon RS. The apparatus transmits a PSSCH using one or more parameters determined based at least in part on the echo RS.

Abstract: A user equipment has been allocated uplink resources, e.g. interlaced uplink channel resources, e.g. interlaced physical uplink shared channel (PUSCH) resources, and non-interlaced uplink channel resources. The UE receives cancellation indication (CI) information which rescinds the allocation for a portion of the previous granted resources. CI is communicated using different formats for resources which are in blocks and resources which are interlaced. The CI for the interlaced resources uses a more efficient format with less overhead to communicate frequency information corresponding to the cancellation for the interlaced channel.

Abstract: Systems, apparatuses, and methods for performing efficient data transfer in a computing system are disclosed. A computing system includes multiple fabric interfaces in clients and a fabric. A packet transmitter in the fabric interface includes multiple queues, each for storing packets of a respective type, and a corresponding address history cache for each queue. Queue arbiters in the packet transmitter select candidate packets for issue and determine when address history caches on both sides of the link store the upper portion of the address. The packet transmitter sends a source identifier and a pointer for the request in the packet on the link, rather than the entire request address, which reduces the size of the packet. The queue arbiters support out-of-order issue from the queues. The queue arbiters detect conflicts with out-of-order issue and adjust the outbound packets and fields stored in the queue entries to avoid data corruption.

Abstract: A system and method for soft locking for a networking device in a network, such as a network-on-chip (NoC). Once a soft lock is established, the port and packet are given transmitting priority so long has the port has an available packet or packet parts that can make forward progress in the network. When the soft lock port's packet parts are not available, the networking device may choose another port and/or another packet. Any arbitration scheme may be used. Once the packet (or all the packet parts) has completed transmission, the soft lock is released.

Abstract: Information retransmission methods and apparatus, base stations, and terminals are provided.

Abstract: Methods, apparatus, and systems for implementing a semi-flexible Receive Segment Coalescing (RSC) control path. Logic for evaluating packet coalescing open flow criteria and close flow criteria are implemented in hardware on a network device that receives packets from one or more networks. packet coalescing open profiles and packet coalescing close profiles are also stored on the network device, wherein each packet coalescing open profile defines a set of packet coalescing open flow criteria to be applied for that packet coalescing open profile and each packet coalescing close profile defines a set of packet coalescing close flow criteria to be applied for that packet coalescing open profile. packet coalescing open flow and close flow profiles are then assigned to packet coalescing-enabled receive queues on the network device and corresponding open and flow criteria are used to perform packet coalescing-related processing of packets in the receive queues.

Abstract: In some embodiments, a method sets a threshold for utilization of a first table, wherein the utilization is based on layer 3 addresses and layer 2 addresses being stored in the first table. When a utilization of the first table does not meet the threshold, the method stores a layer 3 address in the first table. The first table uses a first type of lookup to determine a next hop address for the layer 3 addresses or the layer 2 addresses, and the first table also stores one or more layer 2 addresses. When the utilization of the first table meets the threshold, the method stores the layer 3 address in a second table where the second table uses a second type of lookup to determine the next hop address for layer 3 addresses.

Abstract: In one embodiment, a technique comprises monitoring data transfer over a radio frequency (RF) link between a first device and a second device in a mesh network where the second device is a descendent node and the first device is a parent node. The technique further transfers the data over a power link communication (PLC) when the RF link is inactive. The method also includes broadcasting, by the second device, RF link availability to at least a third device in the mesh network when the RF link with the first device is inactive where the third device has an active link with the second device and the third device is a descendent node of the second device. The method then includes communicating, between the second device and the third device, through the active RF link.

Abstract: Methods, systems, and devices for wireless communications are described. In some systems, user equipment (UEs) may communicate over sidelink channels in a shared (e.g., unlicensed) channel bandwidth. A UE may implement sub-channel-based occupancy time sharing for the unlicensed sidelink to improve resource usage. The UE may gain access to the shared channel bandwidth for an occupancy time and may transmit a sharing indicator indicating a portion of resources of the shared channel bandwidth for the occupancy time. The UE may transmit a time-division multiplexing sharing indicator to share a portion of slots of the occupancy time, a frequency-division multiplexing sharing indicator to share a portion of sub-channels of the shared channel bandwidth, or some combination thereof. A UE receiving the sharing indicator may identify the shared resources and may transmit in these shared resources (e.g., without performing a full contention process for an occupancy time).

Abstract: Aspects described herein relate to receiving, from a base station on a first subband of an unlicensed frequency band, control information that includes a resource allocation of an uplink transmission associated with the first UE and a demodulation reference signal (DMRS) configuration of a downlink transmission associated with a second UE. The apparatus also may obtain one or more measurements of a DMRS within channel activity on a second subband of the unlicensed frequency band using a listen-before-talk (LBT) operation based on the DMRS configuration. The apparatus also may determine whether the channel activity corresponds to the downlink transmission associated with the second UE based on the one or more measurements of the DMRS within the channel activity. The apparatus also may communicate, with the base station on the second subband, the uplink transmission when the channel activity corresponds to the downlink transmission associated with the second UE.
