  • NETWORK NODE AND METHOD FOR MANAGING TRANSMISSION OF CELL REFERENCE SYMBOLS
    Publication number: 20170288822
    Abstract: A method performed by a network node for managing transmission of Cell Reference Symbols, CRS, wherein the network node 110 operates one or more cells and the network node 110is configured to transmit the CRS in a first bandwidthmode. When the network node 110 has identified a cell 130 which is not actively serving any UEs 120, also referred to as an empty cell, the network node 110 applies(302) a reduced CRS bandwidth mode in the first cell 130 in relation to the first bandwidthmode. By applying (302) a reduced CRS bandwidth mode in the empty cell 130, the overall interference of the CRS from the empty cell 130 is reduced, thereby enhancing the performance in cells actively serving UEs 120.

  • Telecommunications method and apparatus for facilitating positioning measurements
    Patent number: 9681414
    Abstract: A wireless terminal (30) capable of operating in a discontinuous mode and method for operation facilitate measurements pertaining to position of the wireless terminal (30). A measurement request message from a radio access network (28) 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 (30) 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.

  • Cell boundary crossing in a unidirectional SFN for high speed trains
    Patent number: 9668192
    Abstract: A first network node has first antenna nodes located along a track and associated with a first cell. Some of them serve a first cell overlap region that overlaps a second cell overlap region of second antenna nodes connected to a second network node. Some first antenna nodes form downlink beams in a same direction with power levels controlled such that respective amounts of overlap between the downlink beams and respective power levels of the downlink beams jointly cause the first cell's overlap region to emulate a cell border for a user equipment travelling at high speed. Emulated cell border signal power is lower at locations closer to an emulated cell outer edge than at more distant locations. Emulated cell border length is sufficient to cause the travelling user equipment to be within the emulated cell border long enough to successfully perform a handover between the first and second cells.

    Abstract: The technology in this application identifies a relay cell serviced by a relay radio node in a radio access network (RAN) of a cellular communications system in which there is a radio connection between the relay radio node and a donor radio base station. The donor radio base station is identified by a RAN donor radio base station cell identifier. A RAN relay cell identifier is determined that uniquely identifies the relay cell within the RAN, the RAN relay cell identifier including a relay cell identifier and a donor base station identifier. The RAN relay cell identifier is then provided or used as needed so that the relay radio node can transmit the RAN relay cell identifier to uniquely identify the relay cell to one or more radio terminals in the RAN.
