The processor may obtains a first control resource set (CORESET) configuration for physical downlink control channels (PDCCHs) in the RACH procedure and obtaining a first search space configuration for the PDCCHs in the RACH procedure from a base station to monitor and receive the PDCCHs in the RACH procedure. | 2018-12-27 |
20180376512 | UPLINK TRANSMISSION METHOD, BASE STATION, AND TERMINAL DEVICE - The present invention discloses an uplink transmission method, a base station, and a terminal device, to implement uplink multiuser scheduling and multiuser resource multiplexing, and save resources. The method in embodiments of the present invention includes: obtaining, by a base station, first configuration information and instruction information, where the first configuration information is channel contention configuration information before uplink data is sent, the instruction information is information that instructs a terminal device to send a channel occupancy indication signal, and the channel occupancy indication signal is used to indicate that a current channel belongs to a radio access technology user; and sending, by the base station, the first configuration information and the instruction information to the terminal device, so that the terminal device sends the channel occupancy indication signal based on the first configuration information and the instruction information. | 2018-12-27 |
20180376513 | APPARATUS AND METHOD FOR RANDOM ACCESS IN WIRELESS COMMUNICATION SYSTEM USING BEAMFORMING - An apparatus implements methods for random access in a wireless communication system using beamforming. A Subscriber Station (SS) measures a best downlink transmission beam among downlink transmission beams transmitted from a Base Station (BS), and transmits Random Access Channel (RACH) information, which includes indication information indicating the best downlink transmission beam, to the BS. The BS receives RACH information which includes indication information indicating a best downlink transmission beam among downlink transmission beams, and detects an RACH sequence and the best downlink transmission beam from the received RACH information. | 2018-12-27 |
20180376514 | METHODS OF UPLINK BROADCAST, TERMINAL DEVICE, AND NETWORK NODE - Embodiments of the present disclosure relate to methods of uplink broadcast, a terminal device, and a network node. There is provided a method of uplink broadcast. The method comprises: initiating uplink broadcast on an uplink channel; and receiving, from at least one network node, a response to the uplink broadcast. There is also disclosed a corresponding terminal device and a network node. | 2018-12-27 |
20180376515 | SELECTING RADIO FREQUENCY CHANNELS FOR CARRIER AGGREGATION IN AN UNLICENSED RADIO FREQUENCY SPECTRUM BAND - A base station may obtain channel usage information identifying usage of one or more unlicensed radio frequency (RF) spectrum bands. The base station may select a selected band, of the one or more unlicensed RF spectrum bands, based on the channel usage information. The base station may select one or more RF channels, of multiple RF channels included in the selected band, based on a congestion value of the selected band. The congestion value may be determined based on values of the channel usage information corresponding to the selected band. The selected RF channel may include an impaired RF channel that may not permit full bandwidth utilization due to constraints. The base station may communicate with user equipment via the one or more RF channels of the selected band. | 2018-12-27 |
20180376516 | Establishing a Datagram Transport Layer Security Connection between Nodes in a Cluster - Some examples relate to establishing a DTLS connection between nodes in a cluster. In an example, an initiator node in a cluster may send a DTLS message of a first type to a responder node. The DTLS message may include a header comprising: a message type field for identifying a message type, a flag field for identifying a message sender and a message category, an initiator connection ID field for identifying a connection ID allocated by the initiator node, and a responder connection ID field for identifying a connection ID allocated by the responder node. In DTLS message of the first type, the message type may represent a connection initiation request message, the initiator connection ID field may include a connection ID allocated by the initiator node, the responder connection ID field may be set to zero, and flag field may identify the initiator node as message sender. | 2018-12-27 |
20180376517 | COMMUNICATION HANDLING IN A WIRELESS COMMUNICATIONS NETWORK - Systems, methods and computer program products for handling communications in a wireless network are described. A message requesting forwarding of communications for a first user device is received. A location of the first user device is determined. One or more second user devices associated with the first user device is identified. A second user device is selected to receive forwarded communications for the first user device. The selected second user device is located within a predefined distance of the location of the first user device. In example implementations, the one or more second user devices are trusted user devices. | 2018-12-27 |
20180376518 | SYSTEM AND METHOD FOR ESTABLISHING A TEMPORARY ELECTRONIC COMMUNICATION CHANNEL TO ALLOW AN INTRODUCTION OF OPERATORS OF ELECTRONIC COMMUNICATION CAPABLE DEVICES - Introductions of the users of electronic communication capable devices can be made temporarily with each other. In one example, a first device presents, visually, audibly, electronically or otherwise, a code that may be received by one or more other devices, either visually, audibly, electronically or otherwise. The code can be used to establish a path for communications, for a predetermined finite period of time, to allow the users to exchange references or profiles with each other without revealing either user's true identity or other personally identifying information, including that which is associated with the mobile or other devices involved in the communication, unless or until a user chooses to do so. | 2018-12-27 |
