  • Publication number: 20210014867
    Abstract: A terminal device receives downlink control information sent by a network device. The downlink control information includes a resource allocation field. The resource allocation field includes ? log 2 ? ? N RB UL 6 ? ? high-order bits and M low-order bits. When the resource allocation field is used to indicate an allocated subcarrier resource, K bit states in bit states of the M bits are used to indicate allocation of subcarrier resources, and a quantity of subcarriers indicated by each of the K bit states is less than 12. The terminal device determines, based on the resource allocation field, whether the resource block or the subcarrier resource is allocated. The terminal device sends information on the allocated resource block or the subcarrier resource. The method and the device provided in embodiments of the application can be applied to a communications system.

  • Patent number: 10893545
    Abstract: This application discloses a resource determining method, a base station, and a user equipment. The method includes: determining a first narrowband resource available to an machine type communication (MTC) terminal according to user equipment (UE) information in a random access process and/or common information of a cell; and transmitting control information and/or data on the first narrowband resource. According to the solutions of this application, in a case where the MTC terminal cannot receive RRC signaling, the narrowband resource available to the MTC terminal can still be determined beforehand, and communication between the MTC terminal and a network-side device is implemented by using the narrowband resource.

  • Publication number: 20200404647
    Abstract: In one embodiment, an apparatus includes a memory comprising instructions and a processor in communications with the memory. The processor is configured to execute the instructions to determine a reference signal received power of user equipment (UE). In response to determining that the reference signal received power is less than or equal to a threshold, it is determined that the UE supports sending a physical random access channel, receiving a random access response message, sending a random access response acknowledgment message, and receiving a contention resolution message. In response to determining that the reference signal received power is above the threshold, it is determined that the UE supports sending the physical random access channel, and receiving the contention resolution message, and it is determined that the UE does not support sending the random access response acknowledgment message and receiving the random access response message.

  • Publication number: 20200257695
    Abstract: A keyword reporting system for mobile applications is disclosed that generates keyword reports for a subject mobile application. The reports include a set of most relevant keywords for the subject mobile application with their associated ranking and result value. The ranking of a keyword is the subject mobile application's position in a search result for the keyword. A result value is determined for each keyword as well, where the result value is the number of mobile applications found in a search result for the keyword. Based on the ranking and result value of each keyword, a weight value is determined for each keyword. The weight value indicates the relevance of the keyword for the subject mobile application. A set of keywords are sorted and selected based on the weight value and a keyword report is generated that includes the set of keywords along with their rankings.

  • Publication number: 20200028766
    Abstract: The application pertains to determining a rank of channel loss extent. A base station sends to a terminal a signaling indicating that there are N ranks of channel loss extent. Each rank has a corresponding number of random access preamble repetitions. The base station receives from the terminal device one or more transmissions of a random access preamble in a first number of repetitions of the random access preamble. The base station determines the rank of channel loss extent according to a random access preamble group in which the received random access preamble is located, or the first number of repetitions of the received random access preamble. A channel loss is a reference signal received power (RSRP). After determining the rank of channel loss extent, the base station determines a second number of repetitions corresponding to the determined rank of channel loss extent, for sending or receiving uplink/downlink information.
