  • Patent number: 11937219
    Abstract: Methods, systems, and devices for wireless communications are described that provide for timing adjustments that may be used in communications between wireless devices in a wireless communications system and signaling of such timing adjustments using physical layer signaling (e.g., layer 1 (L1) signaling). A first timing adjustment may be provided by a parent node to one or more associated child nodes that corresponds to a propagation delay between the parent node and its control node or a relay node through which the parent node communicates with a core network. In some cases, the physical layer signaling used to transmit the first timing adjustment may be a reference signal transmission, a downlink control information transmission, or any combination thereof.

  • Patent number: 11924080
    Abstract: Some embodiments provide a method of identifying packet latency in a software defined datacenter (SDDC) that includes a network and multiple host computers executing multiple machines. At a first host computer, the method identifies and stores (i) multiple time values associated with several packet processing operations performed on a particular packet sent by a first machine executing on the first host computer, and (ii) a time value associated with packet transmission through the SDDC network from the first host computer to a second host computer that is a destination of the particular packet. The method provides the stored time values to a set of one or more controllers to process to identify multiple latencies experienced by multiple packets processed in the SDDC.

  • Patent number: 11909654
    Abstract: Techniques for optimizing segment routing (SR) paths using segment identifiers (SIDs) are disclosed, including determining a packet is to be sent from a first node to a second node of a network using an SR method. The techniques may also include determining a segment quantization factor that is representative of a first number of SIDs that are included in a segment quantization interval. Based at least in part on the segment quantization factor and a cost constraint, an SR path defined by a second number of SIDs to send the packet may be determined. The second number of SIDs may be associated with maximizing the SIDs included in individual ones of segment quantization intervals. The techniques further include modifying the packet to include at least the second number of SIDs and causing the packet to flow from the first node to the second node via the SR path.

  • Patent number: 11877337
    Abstract: Systems, methods, and instrumentalities are disclosed for connectivity supervision and recovery. A WTRU may supervise its capability to transmit and receive data, including in the absence of a control channel (e.g. grant-less transmission). A supervision framework may permit a WTRU to supervise, for example, quality of a feedback channel, quality of reciprocal resources and/or transmission attempts. A supervision process may be a function of a control channel structure or WTRU state. A supervision process may be associated with a quality of service. A supervision process may be based on WTRU transmission for energy/resource efficient operation. Multiple Recovery procedures may be defined. A recovery procedure may be a function of a supervision process. A recovery procedure may be optimized for low latency services. Recovery procedures may involve dedicated resources for recovery, transition to light connection, grant-less resource, etc.

  • Patent number: 11856639
    Abstract: Current wireless networks do not allow machine type communication (MTC) devices to have long discontinuous reception (DRX) cycles or sleep lengths. A long DRX cycle may allow MTC systems and devices to operate with much longer DRX/Sleep cycles/periods. This may facilitate the MTC operations for infrequent system access or infrequent system reaching (e.g. paged once in a week) with no or low mobility and may allow MTC devices to sleep for a long time with low power consumption.

  • Patent number: 11838957
    Abstract: Enhanced Multi-Link Operation (MLO) is performed in this protocol in which non-simultaneous transmit/receive (NSTR) Multi-Link Devices (MLDs) cooperate with each other in sharing a portion of their available Transmit Opportunity (TXOP) toward reducing contention and competition for channel access across the group of cooperating MLDs. The shared TXOP is performed at an MLD level after all links for an NSTR MLD are obtained by stations which do not need to be in part of the same NSTR MLD, thus synchronized transmissions and receptions are performed which eliminate in-device coexistence (IDC) interference in any single NSTR MLD. The time gap while awaiting for all links to be obtained, is also made use of for performing transmission(s) toward increasing data throughput.
