Publication number: 20240129758Abstract: In the method, an access point AP receives action information separately reported by N stations STAs, where N pieces of action information are used to determine a training result of a first neural network of each STA, and N is a positive integer. The AP determines the training result of the first neural network of each STA based on the N pieces of action information, and sends the training result of the first neural network of each STA to the corresponding STA. The training result of the first neural network of each STA is determined based on the action information reported by the N STAs, instead of only the action information of the STA. This can improve a prediction capability of the first neural network, help improve a capability of each STA to predict channel access behavior of another STA, and improve a system throughput and reduce a communication latency.Type: ApplicationFiled: December 15, 2023Publication date: April 18, 2024Inventors: Ziyang GUO, Peng LIU, Jiajun LUO, Xun YANG, Yunbo LI

Patent number: 10122783Abstract: In order to ingest data from an arbitrary source in a set of sources, a computer system accesses predefined configuration instructions. Then, the computer system generates a dynamic data-ingestion pipeline that is compatible with a Hadoop file system based on the predefined configuration instructions. This dynamic data-ingestion pipeline includes a modular arrangement of operators from a set of operators that includes: an extraction operator for extracting the data of interest from the source, a converter operator for transforming the data, and a quality-checker operator for checking the transformed data. Moreover, the computer system receives the data from the source. Next, the computer system processes the data using the dynamic data-ingestion pipeline as the data is received without storing the data in memory for the purpose of subsequent ingestion processing.Type: GrantFiled: November 18, 2015Date of Patent: November 6, 2018Assignee: Microsoft Technology Licensing, LLCInventors: Lin Qiao, Yinan Li, Sahil Takiar, Ziyang Liu, Narasimha R.

Patent number: 9991998Abstract: The present invention discloses a method, an apparatus and a computer program for resource contention in device-to-device communication links. The method partitions the time-frequency radio resource grid with a resource block set forming the resource unit in the grid, for all available, used and unusable frequency bands around a given virtual central frequency. Each resource block set is partitioned into a common control channel and a data channel. With a given procedure of control data transmission between transmitting and receiving user terminals, the resources are competed and shared. Frequency shifting with short distance frequency change or frequency transference with a larger frequency hopping into a free radio resource is available. The competition procedure is done in order to fairly share the frequency bands as a function of time between different device-to-device communication links in a localized manner.Type: GrantFiled: November 25, 2011Date of Patent: June 5, 2018Assignee: Avago Technologies General IP (Singapore) Pte.

Patent number: 9015169Abstract: A method for tenant placement in a multi-tenant system is shown that includes creating a weighted graph of tenants and sharing relationships between tenants, where a weight for each tenant and each sharing relationship represents an associated degree of resource consumption; and adding one or more tenants to a database using a processor based on said weighted graph and a database capacity, such that the combined weight of the added tenants and the sharing relationships belonging to the added tenants are within the database capacity. If a tenant cannot be added to the database without exceeding the database capacity, a new database is created and the one or more tenants are added to the new database, subject to a new database capacity. The adding and creating steps are repeated until all tenants have been added to a database.Type: GrantFiled: November 23, 2012Date of Patent: April 21, 2015Assignee: NEC Laboratories America, Inc.Inventors: Ziyang Liu, Vahit Hakan Hacigumus

Patent number: 8874587Abstract: Methods for generating a data fetching plan in a multi-tenant system include placing tenants in consecutively allocated databases according to a weighted graph of tenants and sharing relationships between tenants, where at least one sharing relationship includes multiple accessing tenants accessing a given set of data from a provider tenant. For each sharing relationship, if a current database has one or more accessing tenants and does not have the provider tenant, data is fetched from the latest-allocated database prior to the current database that has accessing tenants, if such a database exists; if a current database has the provider tenant, data is provided to the earliest-allocated database after the current database that has accessing tenants if such a database exists. The fetching and providing steps are repeated for each allocated database.Type: GrantFiled: November 23, 2012Date of Patent: October 28, 2014Assignee: NEC Laboratories America, Inc.Inventors: Ziyang Liu, Vahit Hakan Hacigumus
