  • Patent number: 9037155
    Abstract: Techniques for determining time of arrivals (TOAs) of signals in a wireless communication network are described. Each cell may transmit (i) synchronization signals on a set of contiguous subcarriers in the center portion of the system bandwidth and (ii) reference signals on different sets of non-contiguous subcarriers distributed across the system bandwidth. A UE may determine TOA for a cell based on multiple signals transmitted on different sets of subcarriers. The UE may perform correlation for a first signal (e.g., a synchronization signal) from the cell to obtain first correlation results for different time offsets. The UE may perform correlation for a second signal (e.g., a reference signal) from the cell to obtain second correlation results for different time offsets. The UE may combine the first and second correlation results and may determine the TOA for the cell based on the combined correlation results.

  • Patent number: 9037174
    Abstract: The present invention discloses a method in a network node (310, 610) for improving radio network characteristics in a wireless communications network (300, 600) comprising M cells. The method forms at least a first subgroup SC of cells comprising K cells, where K<=M, for coordinated transmission and/or reception between the cells. The network node (310, 610) determines (410, 730) at least one weight aij associated with a first cell Ci and a second cell Cj in the network. The weight a, indicates a radio network characteristic dependent on the cells Ci and Cj. The network node (310, 610) forms (470) the subgroup SC of cells by selecting at most K cells from the M cells, in such a way that a function of the weights aij for each cell Ci and Cj in the subgroup SC is approximately maximized. The network node (310, 610) sends (480) a message to each cell Ck in the subgroup SC, relating said cell Ck to said subgroup SC.

  • Patent number: 9020499
    Abstract: A method and apparatus for fast cell selection by a mobile wireless device. The mobile wireless device detects when a first wireless cell fails a set of stored suitability criteria and searches for and locates a set of candidate wireless cells to associate with. The mobile wireless device measures at least one received signal metric for each candidate wireless cell in the set of candidate wireless cells. When a candidate cell in the set of candidate wireless cells is identically the first wireless cell, the mobile wireless device evaluates the suitability of the candidate wireless cell using the stored set of suitability criteria for the first wireless cell and the measured at least one received signal metric for the candidate wireless cell. The mobile wireless communication device associates with the candidate wireless cell when the candidate wireless cell meets the stored set of suitability criteria.
