An inline compression of the processed write data may be performed to compress and store the processed write data in a compressed page at a location associated with the compression index. In some examples, the compressed page may include a compression metadata having a reference count, a compressed page offset, and a virtual page address.

Abstract: Aspects of the present disclosure provide techniques to enable enhanced machine type communication (s) (eMTC) and/or narrowband Internet-of-Things (NB-IoT) devices to transition to idle mode after releasing a connection, such as a radio resource control (RRC) connection, more quickly than with previously known techniques. An example method includes determining, based on an indication received in a narrowband signal on a narrowband region of a bandwidth comprising a plurality of narrowband regions, whether to wait for a delay period, determined based on a configuration received from a network entity, before releasing a radio resource control (RRC) connection and releasing the RRC connection at a time in accordance with the determination.

Abstract: End-to-end automated performance of actions in response to receiving unstructured data from one of a plurality of action request channels and/or applications. A centralized service/engine is implemented that provides for consistent and reliable action results regardless of which channel/application initiated the request and/or which entity the request is associated with. Results consistency is further realized by structuring the unstructured data and extracting data elements therefrom that provide for determination of a predetermined action categories. The action categories define the automated processes, flows and/or tools required to complete the action.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) and another device (e.g., another UE) may transmit messages on a shared channel accessed in a half-duplex manner (e.g., within a vehicle-to-everything (V2X) network). The UE and the other device may transmit messages on semi-persistently scheduled (SPS) resources. A message of the UE and a transmission of the other device may collide (e.g., be transmitted in the same subframe). The UE may employ muting and measuring, in which the UE may refrain from transmitting on a SPS resource and may detect the transmission of the other device. Upon detection of other transmissions, the UE may perform resource reselection. During resource selection or resource reselection, the UE may exclude an entire subframe of candidate resources if one of the candidate resources of the subframe is mapped to a resource associated with a transmission from another device.

Abstract: Aspects directed towards synchronizing out of coverage (OOC) vehicle-to-everything (V2X) communications are disclosed. In one example, a scheduled entity detects a loss of a synchronization signal associated with a V2X communication by detecting when a timing uncertainty value or error value is greater than a threshold value. Packet timing information is then received in response to the loss of the synchronization signal from at least one user equipment (UE) synchronized with the synchronization signal. The scheduled entity then maintains the V2X communication by performing a timing adjustment based on the packet timing information.

Abstract: The embodiment herein provides a system and method for providing a novel leader election mechanism in distributed systems that is randomized in twin dimensions of space and time using the concept of a colliding random walk (CRW). Leader election is randomized in space in terms of the node identified as the leader and the time taken to identify the leader. A source node is enabled to generate left and right coupons in a quantum resistant manner for random walks. A novel fault tolerance mechanism is provided to identify several leaders for same set of coupons. In this system and method, the source vertex generates multiple CRWs for each piece of work that needs to be done. The fault tolerance mechanism reduces the time to collision, increases the number of leaders and also offers increased resilience and tolerance to faults.

Abstract: The embodiments herein provide a fair, high speed and lightweight consensus mechanism for leader election in distributed systems using coupons. The consensus mechanism uses a leader election mechanism that is randomized in twin dimensions of space and time using the concept of a colliding random walk. A source node is enabled to generate left and right coupons in a quantum resistant manner for random walks. Two novel coupon processing mechanisms called Process Execution Time Synchronization (PETS) mechanism and Single Queue (SQ) mechanism are used to process the coupons and find matches. The use of PETS optimizes memory and time requirements while SQ is extremely fast and efficient to handle large volumes of coupons. Also, the coupon forwarding to neighbouring nodes is performed based on three algorithms namely Uniform, Delay and Adaptive Delay forward. These forwarding algorithms effect high fairness even in case of open networks.

Abstract: Systems and methods are provided for managing digital identities associated with users. One exemplary method includes receiving, at a computing device, an encrypted message from a communication device associated with a user where the messaging includes a changed attribute for the user.

The method then further includes broadcasting a pending status of the digital identity of the user to a relying party for the digital identity, and storing a certification of the changed attribute, received from the relying party in response to the pending status, based on verification of the changed attribute by the relying party.

Abstract: A method, apparatus, and computer-readable medium at a transmitting user equipment (UE) in a distributed cellular vehicle-to-everything environment are disclosed to determine a schedule for transmissions on subchannels of multiple frequencies based on a set of UE-specific, dynamic, and performance related metrics or criteria. The metrics may include an estimated number of users on a subchannel, a best-bandwidth fit, channel loading conditions, transmission range, and quality requirements of an application, among others. Such a schedule for transmissions on subchannels of multiple frequencies may result in either an improved capacity utilization, an improved communication quality, or both.
