  • Publication number: 20220271898
    Abstract: A method and system for minimizing the control overhead in a multi-carrier wireless communication network that utilizes a time-frequency resource is disclosed. In some embodiments, one or more zones in the time-frequency resource are designated for particular applications, such as a zone dedicated for voice-over-IP (VoIP) applications. By grouping applications of a similar type together within a zone, a reduction in the number of bits necessary for mapping a packet stream to a portion of the time-frequency resource can be achieved. In some embodiments, modular coding schemes associated with the packet streams may be selected that further reduce the amount of necessary control information. In some embodiments, packets may be classified for transmission in accordance with application type, QoS parameters, and other properties. In some embodiments, improved control messages may be constructed to facilitate the control process and minimize associated overhead.

  • Patent number: 11401156
    Abstract: The present invention discloses a micro-electro-mechanical system silicon on insulator (MEMS SOI) pressure sensor and a method for preparing the same. The pressure sensor includes a bulk silicon layer, a buried oxide layer, a substrate, a varistor, a passivation layer, and an electrode layer. The varistor is obtained by means of photolithography and ion implantation on a device layer of an SOI wafer. The passivation layer is SiO2 formed by means of annealing treatment on the SOI wafer. An annealing atmosphere is one of pure O2, a gas mixture of O2/H2O, a gas mixture of O2/NO, a gas mixture of O2/HCl, and a gas mixture of O2/CHF3. By means of the annealing treatment, the damage to a surface of the buried oxide layer as a result of over-etching during formation of the varistor by means of photolithography is eliminated and the unstability of the sensor caused by body and interface defects of the passivation layer and trapped charges thereof is resolved.

  • Patent number: 11403306
    Abstract: Techniques for implementing a non-relational database that makes efficient use of collections within the database. For one or more collections, two or more sub-collections can be created for storing documents. Each collection can be configured as a single partition entity or a partitioned entity within the database. Each sub-collection is identified by a sub-collection identifier. If the collection is configured as a partitioned entity, then a partition key can be determined for documents to be accessed in the collection. The partition key can be extended with the sub-collection ID to form a compound property (sub-collection ID, partition key) that determines placements of the respective documents in the identified sub-collection across partitions of the collection. If the collection is configured as a single partition entity, then a field for the partition key is ignored and the respective documents are placed in the identified sub-collection within the single partition of the collection.

  • Publication number: 20220231874
    Abstract: A mobile station may comprise a receiver to receive, from a base station, a broadcast signal indicating a TDD configuration of uplink OFDM symbols and downlink OFDM symbols. The receiver may receive an indication of a symbol range and a subchannel range for use in transmission of CQI feedback. The mobile station may receive first downlink data and transmit first uplink data, using the TDD configuration, wherein the first uplink data comprises CQI feedback information transmitted in accordance with the symbol range and the subchannel range. The receiver may receive second downlink data, from the base station, on a different frequency as the first uplink data is transmitted, while the first uplink data is transmitted.

  • Patent number: 11388034
    Abstract: A multi-carrier cellular wireless network (400) employs base stations (404) that transmit two different groups of pilot subcarriers: (1) cell-specific pilot subcarriers, which are used by a receiver to extract information unique to each individual cell (402), and (2) common pilots subcarriers, which are designed to possess a set of characteristics common to all the base stations (404) of the system. The design criteria and transmission formats of the cell-specific and common pilot subcarriers are specified to enable a receiver to perform different system functions. The methods and processes can be extended to other systems, such as those with multiple antennas in an individual sector and those where some subcarriers bear common network/system information.
