  • Patent number: 10548124
    Abstract: Methods, apparatuses, systems, and devices are described for wireless communication. In one method, a control format indicator value for a frame may be received over a physical carrier in a shared spectrum. Based on the control format indicator value, a number of subframes of the frame to be used by a base station for downlink transmissions over the physical carrier may be determined. The control format indicator value may indicate an end of transmission, if data is to be transmitted during the frame, a number of subframes to be used for transmission, or whether the current subframe is the final subframe used for transmission. In some cases, a user equipment (UE) may use the control format indicator value to determine a sleep schedule. Further, ACK/NACK transmissions by a UE may be scheduled based on the control format indicator value.

  • Patent number: 10484138
    Abstract: A first communication subscriber transmits a first data packet comprising data and an identification character to the second communication subscriber. The first communication subscriber and the second communication subscriber respectively determine a first and a second acknowledgement character on the basis of the identification character. The second communication subscriber transmits a second data packet comprising the second acknowledgement character back to the first communication subscriber. The first communication subscriber can thus check, on the basis of the second acknowledgement character, whether the first data packet arrived at the second communication subscriber.

    Abstract: Various methods of control-less data transmission for NB-IoT/NR devices have been proposed to improve efficiency and system capacity in cellular networks. In a first embodiment, a PDCCH-less operation is performed between eNB and UE. UE will blindly decode some PDSCH subframes according to the parameters configured by higher layer. In a second embodiment, a PDCCH-lite operation is performed between eNB and UE. UE may use one PDCCH to schedule more than one subsequent PDSCH resources. In a third embodiment, an extremely compact DCI (E-DCI) format is used between eNB and UE. When the same assignment parameters are used by the eNB for the UE, DCI overhead may be reduced by E-DCI.

  • Patent number: 10028249
    Abstract: A person may utilize multiple connected devices, such as smart watches, user equipments (UEs), smartphones, tablet computers, and/or the like, which may each be assigned unique phone numbers. Operators may assign a common phone number to the multiple connected devices; however, the phone number is not used in the access stratum path of a radio access technology resulting in multiple paging procedures being performed for the multiple connected devices. In implementations, described herein, a first UE, such as a smartphone, may obtain paging information associated with decoding paging messages for a second UE, such as a smart watch. The first UE may use the paging information to decode a paging message of a combined paging cycle established for the first UE and the second UE, thereby obviating a need for multiple paging cycles for the first UE and the second UE.

  • Patent number: 9992004
    Abstract: Methods, systems, and devices are described for wireless communication. Wireless devices may exchange data using Medium Access Control (MAC) layer units known as transport blocks. The transport blocks may be partitioned into code block clusters (CBCs), each of which may include one or more code blocks. A receiving device may attempt to decode a transport block and send acknowledgement (ACK) and negative-acknowledgment (NACK) information to the transmitting device based on the whether each CBC was successfully decoded. The transmitting device may retransmit a redundancy version of a CBC for each NACK received. The transmitting device may group CBCs in segments of a transport block according to redundancy version. In some cases, the transmitting device may send a control message in a control channel which indicates the composition of the transport block.

  • Patent number: 9967310
    Abstract: A system that stores sets of data blocks in extents located in storage devices is described. During operation, a receiving device receives, through an RPC framework, a first call asking to transfer an extent from a sending device to the receiving device. In response, the receiving device opens a port for a data connection that operates outside the RPC framework. The receiving device makes a second call, to the sending device through the RPC framework, asking to stream the extent to the port. The receiving device subsequently receives the extent from the sending device through the port and computes a checksum for the extent. The receiving device also receives a return from the second call, including a checksum for the extent computed by the sending device. If the computed checksum matches the received checksum, the receiving device returns the first call to indicate the transfer operation completed successfully.

  • Patent number: 9894557
    Abstract: A system for circumventing retransmission of dropped data packets from a source mobile station is envisaged. The source mobile station is coupled to a destination mobile station. The source mobile station and destination mobile station are coupled to a source eNodeB and a destination eNodeB respectively. The source eNodeB and the destination eNodeB are configured to interpret any No Acknowledgement (NACK) messages transmitted from the destination mobile station on account of non receipt of data packets transmitted from the source mobile station, and accordingly retransmit, from a buffered data packet pool, the data packets corresponding to the NACK messages. The source eNodeB and destination eNodeB prevent NACK messages from being retransmitted to the source mobile station thereby obviating the need for the source mobile station to retransmit dropped data packets, and rendering the source mobile station available for any subsequent data transfer operations.
