  • Patent number: 9344228
    Abstract: In wireless communication networks that use ARQ/HARQ feedback protocols, when a first device receives an apparent HARQ ACK from a second device, the first device may make a new transmission using a HARQ Channel ID whose previous usage was under conditions indicating a likelihood of error in the ACK. When the second device receives the new transmission, the reuse of that HARQ Channel ID in a new transmission rather than a retransmission lets the second device know that its previous NAK transmission was incorrectly received as an ACK.

  • Patent number: 9125091
    Abstract: Technology is discussed for self-optimization approaches within wireless networks to optimize networks for energy efficiency, load capacity, and/or mobility, together with new, supporting channel state measurements and handover techniques. New, Channel State Information-Reference Signals (CSI-RSs) for yet-to-be-configured Cell-IDentifications (Cell-IDs) can be used to determine whether adjacent transmission cells can provide coverage for transmission cells that can be switched off for energy efficiency during formation of a Single Frequency Network (SFN). New approaches are also discussed to facilitate mobility within such a network. The new CSI-RSs and mobility approaches can also be used to split up such a SFN when changing load demands so require. Additionally, such new approaches can be used to create a SFN with a common Cell-ID where high mobility is required, such as near a roadway, and to break it up where high capacity is required, such as during a period of traffic congestion.
