  • Method and Apparatus for Generating an Indication of Remaining Battery Life for a Wireless Device
    Publication number: 20180115879
    Abstract: A method (100) for generating an indication of remaining battery life for a wireless device is disclosed. The wireless device is positioned in an installation location and operable for radio communication with a communication network node. The method comprises estimating a signal loss between the wireless device in the installation location and the communication network node (120) and mapping the estimated signal loss to an indication of remaining battery life for the wireless device (130). The mapping is based on remaining battery capacity for the wireless device and estimated energy consumption of the wireless device for radio communication, the estimated energy consumption being generated from the estimated signal loss and determined communication parameters for the wireless device.

  • Uplink transmit diversity
    Patent number: 9876541
    Abstract: The present disclosure discloses a method in a wireless access network node for controlling a UE. The UE comprises at least two transmit antennas, and is capable of uplink transmit diversity. There is an antenna weight associated with each transmit antenna. First, the wireless access network node determines that the antenna weights of the user equipment may be controlled. Then, it creates a control signal that comprises control information and transmits it to the user equipment. The control information controls a UE autonomous selection of the antenna weights in the UE.

  • Method for sharing resources using individual HARQ processes
    Patent number: 9860027
    Abstract: The network node of a cellular network assigns a first part of a shared radio resource to a first User Equipment, UE, for uplink transmissions in the cell, and instructs the first UE to apply a first UE-specific Hybrid Automatic Repeat Request, HARQ, process for transmitting on the assigned first part. The network node also assigns a second part of the shared radio resource to a second UE for uplink transmissions in the cell, and instructs the second UE to apply a second UE-specific HARQ process for transmitting on the assigned second part, the second HARQ process being separate from the first HARQ process. The network node then receives data transmitted from the first UE on the assigned first part based on the first HARQ process and data transmitted from the second UE on the assigned second part based on the second HARQ process.

  • Transmitting and Receiving Narrowband Synchronization Signals
    Publication number: 20170373900
    Abstract: A radio network node (10) is configured to transmit a narrowband primary synchronization signal (NB-PSS) and a narrowband secondary synchronization signal (NB-SSS) within a synchronization signal period comprising multiple frames. The radio network node (10) maps the NB-PSS to the same one or more subframes within each frame in which the NB-PSS is to be transmitted. The radio network node (10) also maps the NB-SSS to the same one or more subframes within each frame in which the NB-SSS is to be transmitted, including at least one frame in which the NB-PSS is to be transmitted. The radio network node (10) does so by mapping the NB-SSS to one or more subframes that differ from the one or more subframes to which the NB-PSS is mapped. The radio network node (10) transmits the NB-PSS and NB-SSS within the synchronization signal period according to this mapping.
