  • User equipment, network node, and methods for managing an extended discontinuous reception cycle mode
    Patent number: 9900928
    Abstract: A method in a User Equipment, UE, for managing an extended Discontinuous Reception, DRX, cycle mode. The UE is operating in a network and is in a Radio Resource Control, RRC, connected state. The UE enters (401) the extended DRX cycle mode when a first criterion is satisfied. The first criterion relates to anyone or more out of that the UE has not been scheduled by the network during a specific time duration, that the UE has completed a predefined or configured number of long DRX cycles when being in a long DRX cycle mode, that the UE has received an order from the network to enter to the extended DRX cycle mode.

  • Method and Apparatus for Operating Configuration Adaptation for Interruption of Signal Transmission
    Publication number: 20180013623
    Abstract: The operating configuration at a node in a wireless communication network, at a neighboring node in the network, and/or at one or more wireless devices supported by the network, is updated based on determining timing information for an impending interruption of a radio link in the network to avoid erroneous operation during the impending interruption, which interruption is associated with an external system. The determination of interruption timing, which may be inferred, e.g., from detecting prior interruptions, or which may be known from information about the external system, and the modification of the operating configuration(s) permits the network to operate with greater stability, control, and accuracy during the interruptions than would be possible if the interruptions were simply treated as intermittent radio link failures.

  • Methods and apparatus for supporting inter-frequency measurements
    Patent number: 9867160
    Abstract: A radio network node receives an indication from the user equipment that the user equipment is going to perform an inter-frequency measurement for positioning, which inter-frequency measurement requires measurement gaps. The radio network node may determine a measurement gap pattern for performing the inter-frequency measurement and may signal, to the user equipment, information to initiate use of the determined measurement gap pattern in the user equipment. Alternatively the user equipment configures the measurement gap pattern itself based on a set of pre-defined rules.

  • IMPROVED HANDLING OF BACKUP PATHS IN RADIO ACCESS NETWORKS
    Publication number: 20170318507
    Abstract: The present disclosure relates to a method performed in a radio communications network which is configured to enable multipath communication. The method comprises providing an explicit indication that a path within a multipath connection is a backup path prior to establishment on or handover to a radio link of the backup path, transmission of the explicit indication to the base station, where it is interpreted. This allows an early indication that the path is a backup path and allows the base station to handle and prioritise use of radio network resources and/or connection characteristics for the radio link. The explicit indication may be in the radio level signalling or in handover signalling.

  • HANDLING HANDOVER OF AN UE IN CASE CELL SPECIFIC REFERENCE SIGNALS INTERFER WITH A PHYSICAL DOWNLINK CONTROL CHANNEL
    Publication number: 20170303171
    Abstract: A method performed by a network node, for handling handover of a user equipment (UE), wherein the network node serves a first cell comprising one or more UEs. When the network node has detected that a Signaling Radio Bearer (SRB) is determined to be scheduled for a UE in handover from the first cell to a second cell, the network node increases the number of OFDM-symbols included in a control region of a downlink OFDM-subframe sent in the first cell in a Transmission Time Interval (TTI) related to the handover. By increasing the number of OFDM-symbols of the control region only during the handover, the physical downlink control channel (PDCCH) is spread in time into symbols not polluted by CRS symbols from neighboring cells. Thereby the number of unsuccessful handovers and lost service is effectively reduced.

  • NETWORK NODE AND METHOD FOR MANAGING POWER OF CELL REFERENCE SYMBOLS
    Publication number: 20170289925
    Abstract: A method performed by a network node for managing power of Cell Reference Symbols, CRS, wherein the network node operates one or more cells and the network node is configured to transmit the CRS in a first power mode. When the network node identifies a first cell which is not actively serving any UEs, which cell is also referred to as an empty cell, the network node reduces the power of the CRS in the first cell in relation to the first power mode. By reducing the power of the CRS, the overall interference of the CRS from the empty cell is reduced, thereby enhancing the performance in cells actively serving UEs.

    Abstract: A wireless terminal capable of operating in a discontinuous mode and method for operation facilitate measurements pertaining to position of the wireless terminal. A measurement request message from a radio access network indicates that measurements are to be performed by the wireless terminal on downlink signals transmitted by the base station or by the base station on downlink signals transmitted by the base station. As a result of or after receiving the message, operation of the wireless terminal changes from a discontinuous mode to a modified mode to facilitate performance of the measurements. Relative to the discontinuous mode at least one of following are shortened or eliminated in the modified mode: (i) the non-reception periods, and (ii) the non-transmission periods.
