    Abstract: A method of transmitting data over a wireless communications channel comprises transmitting a plurality of blocks (70), in which each block (70) comprises a plurality of symbols (71, 72, 73, 74, 75) representing the data. The symbols are transmitted using time packing, or Faster-than-Nyquist signalling, such that each symbol in a block overlaps in the time domain with at least one other symbol in the block. A null guard interval (77) is included in each block, having a length that means that inter-symbol interference is not a cause of inter-block interference.

The PLC nodes are configured to detect a zero crossing of the power line wave form and transmit or receive data within time slots defined with respect to the detected zero crossing. In other embodiments, the time slots may be synchronized using a frame sync signal, an external signal, or polling. In various embodiments, the time slots may be random access or assigned. In some embodiments, the modem and/or node may be placed in a sleep mode when not communicating to reduce power consumption and be awaken when an allocated time slot is approaching.

  • Patent number: 10172048
    Abstract: A method and system for the UE and RNC to reduce transmission latency and potentially prevent loss of PDUs upon a MAC-hs layer reset. The RNC generates a radio resource control (RRC) message with a MAC-hs reset indication. The MAC reset indication requires the UE to flush buffers for configured HARQ processes, disassemble MAC protocol data units (PDUs) in the reordering buffers, deliver MAC-d PDUs to a MAC-d layer, and configure the MAC-hs to receive new data.

  • Patent number: 10159077
    Abstract: A sending node sends information to a receiving node. Said nodes are comprised in a wireless communication network. Communication between said nodes is associated with a first cell. The sending node obtains predefined scrambling for scrambling the information and which predefined scrambling is specific for the first cell. The receiving node correspondingly obtains de-scrambling. The sending node sends, to the receiving node, the information repeatedly a certain number of times, wherein each time the information is sent it is scrambled differently based on the obtained scrambling. Each time the information is received by the receiving node it is de-scrambled differently based on the obtained de-scrambling.

  • Patent number: 10149316
    Abstract: The present invention relates to granting time intervals for transmitting a control signal burst and, more particularly, to methods and devices for granting Dedicated Physical Control Channel (DPCCH) bursts for Wideband Code Division Multiple Access (WCDMA). A base station determines whether a predetermined condition for transmitting a grant signal is satisfied and, if so, determines a schedule for receiving a control signal burst from a mobile device and transmits, in accordance with the determined schedule, the grant signal to at least said mobile device. Correspondingly, a mobile device transmits a report to a base station causing it to determine, in accordance with the report, a schedule for transmitting a control signal burst. Then the mobile device receives grant signals in accordance with the determined schedule and transmits a control signal burst in accordance with the grant signal.

  • Patent number: 10142788
    Abstract: Systems and methods including mobile devices determining their location using a location determination system, such as a global positioning system. A database stores the identifiers of cells representative of predefined regions in a hierarchical grid system. The location coordinates as function of time are converted to visitation patterns of the mobile devices to the predefined regions, based on converting the coordinates to cell identifiers and searching the database to find matches between the cell identifiers representing the regions and the cell identifiers representing the mobile device locations. For example, mobile devices having similar visitation patterns can be identified and divided into two groups; and information relevant to a region is transmitted to one of the group but not another. The visitation patterns of the two group after the transmission is identified and compared to measure a difference.
