  • Publication number: 20210105102
    Abstract: A user equipment (UE) configured for operation in a fifth-generation new radio (5G NR) system may be configured for Type-2 Hybrid automatic repeat request (HARQ) acknowledge (ACK) (HARQ-ACK) codebook grouping and HARQ-ACK retransmission. The UE may decode a downlink control information (DCI) format for scheduling a physical downlink shared channel (PDSCH) group of one or more PDSCHs. The DCI format may include a downlink assignment index (DAI) comprising a counter DAI (C-DAI) for the scheduled PDSCH group. The DCI format may also include a total DAI (T-DAI) for at least one of the scheduled PDSCH group and a non-scheduled PDSCH group.

  • Patent number: 10972991
    Abstract: Disclosed is a method of transmitting/receiving a signal by a transmission device in a mobile communication system. The method includes: receiving information related to synchronization signals from a Base Station (BS); transmitting a first synchronization signal based on the received information; and receiving a second synchronization signal corresponding to the first synchronization signal based on the received information. When a UE cannot receive a synchronization signal from the BS or is located beyond a coverage of the BS, or when the BS cannot operate due to an emergency or disaster situation, UEs can configure self synchronization therebetween in a predetermined area without any assistance from the BS and thus broadcast and unicast transmission are possible between the UEs based on the synchronization.

  • Patent number: 10971607
    Abstract: Some embodiments include methods of forming charge storage transistor gates and standard FET gates in which common processing is utilized for fabrication of at least some portions of the different types of gates. FET and charge storage transistor gate stacks may be formed. The gate stacks may each include a gate material, an insulative material, and a sacrificial material. The sacrificial material is removed from the FET and charge storage transistor gate stacks. The insulative material of the FET gate stacks is etched through. A conductive material is formed over the FET gate stacks and over the charge storage transistor gate stacks. The conductive material physically contacts the gate material of the FET gate stacks, and is separated from the gate material of the charge storage transistor gate stacks by the insulative material remaining in the charge storage transistor gate stacks. Some embodiments include gate structures.

  • Publication number: 20210098697
    Abstract: Methods, systems, and devices for fabrication of memory cells are described. An electrode layer may have an initial thickness variation after being formed. The electrode layer may be smoothened prior to forming additional layers of a memory cell, thus decreasing the thickness variation. The subsequent layer fabricated may have a thickness variation that may be dependent on the thickness variation of the electrode layer. By decreasing the thickness variation of the electrode layer prior to forming the subsequent layer, the subsequent layer may also have a decreased thickness variation. The decreased thickness variation of the subsequent layer may impact the electrical behavior of memory cells formed from the subsequent layer. In some cases, the decreased thickness variation of the subsequent layer may allow for more predictable voltage thresholds for such memory cells, thus increasing the read windows for the memory cells.

  • Publication number: 20210092441
    Abstract: Innovations for signaling state of a decoded picture buffer (“DPB”) and reference picture lists (“RPLs”). In example implementations, rather than rely on internal state of a decoder to manage and update DPB and RPLs, state information about the DPB and RPLs is explicitly signaled. This permits a decoder to determine which pictures are expected to be available for reference from the signaled state information. For example, an encoder determines state information that identifies which pictures are available for use as reference pictures (optionally considering feedback information from a decoder about which pictures are available). The encoder sets syntax elements that represent the state information. In doing so, the encoder sets identifying information for a long-term reference picture (“LTRP”), where the identifying information is a value of picture order count least significant bits for the LTRB. The encoder then outputs the syntax elements as part of a bitstream.
