  • Indicating SI updates for CRS muting to LTE-M devices in RRC connected mode
    Patent number: 11324011
    Abstract: A network node configures a downlink connection to a wireless terminal to transmit channel specific reference signals, CRS, according to a first CRS muting configuration. In the first CRS muting configuration, CRS is transmitted in a first plurality of physical resource blocks, PRBs. Prior to a modification period boundary, the network node transmits a message to the wireless terminal indicating a second CRS muting configuration as a current CRS muting configuration. In the second configuration, CRS is transmitted in a second plurality of PRBs that is less than the first plurality of PRBs. The network node continues to transmit CRS according to the first CRS muting configuration after transmitting the message to the wireless terminal. At the modification period boundary, the network node switches from the first CRS muting configuration to the second CRS muting configuration.

  • Sync network
    Patent number: 11258699
    Abstract: The provision of redundancy in a sync network, which protects the sync network against faults, such as broken cables in the sync network. The gateway comprises a sync propagation module configured to provide redundant sync requests that are sent along different pathways in the sync network. These sync requests are sent to towards different masters in the sync network. If a fault occurs at a point in one of the paths, the gateway will still receive a sync acknowledgment returned along the other path. Furthermore, the use of redundant sync networks, propagating the sync requests across different paths, allows fault detection in the wiring to be detected.
