  • Patent number: 10397856
    Abstract: Provided is a method and wireless communication system that includes a HetNet, a serving cell with an associated coverage area and multiple additional low power nodes (LPNs) deployed in one or more clusters of cells in the coverage area. The LPNs transmit an associated discovery signal based on the timing of the associated small cell. The serving cell is configured to determine the timing of the cells and therefore the transmission pattern of the discovery signals and the serving cell configures measurement gaps such that the discovery signals are transmitted during the measurement gaps. The network is adapted to accomplish this for various degrees of granularity and timing measurement inaccuracies by placing the measurement gaps and/or adjusting the discovery signal (DS) transmission scheme accordingly.

  • Patent number: 10117115
    Abstract: A method, system and non transitory, tangible computer readable storage medium provides for controlling the BLER (block error rate) in a digital communication system. The outer loop control of the system discounts responses sent by a receiver to data transmission from a transmitter that were sent during a receiver outage event. Either the NACKs or both the ACKs and NACKs sent by the receiver during receiver outage are discounted by the outer loop control which adapts subsequent transmissions by either directly adjusting transmission parameters or by adjusting the selection of transmission parameters. The adapting may be based on individual NACKs and ACKs or after establishing a BLER.
