  • Patent number: 12010712
    Abstract: A network node determines a first transmission parameter defining first time and/or frequency resources of a downlink control channel and selects between the first transmission parameter and a second transmission parameter to identify a receiver configuration for a wireless device. The second transmission parameter defines second time and/or frequency resources of the downlink control channel that are different from the first time and/or frequency resources. The network node transmits a first signal to the wireless device according to the first transmission parameter. The first signal comprises the second transmission parameter and a configuration indication indicating the receiver configuration selected by the network node for the wireless device. The network node transmits one or more second signals to the wireless device in accordance with the receiver configuration identified for the wireless device. The wireless device receives the first signal and the one or more second signals accordingly.

  • Patent number: 11825473
    Abstract: A method performed by a user equipment (UE) in idle mode, for determining common search space (CSS) for NB-IoT paging is disclosed. The method comprises determining a set of periodic subframes as a Paging Occasion (PO) subframe pattern. The method further comprises monitoring a starting subframe of paging CSS for a Radio Network Temporary Identifier (RNTI). The starting subframe of paging CSS is determined as follows: a first subframe (SF0) defined by the Paging Occasion subframe pattern, is used when SF0 is determined to be a valid downlink subframe. A next valid downlink subframe after SF0 is used when SF0 is determined to be an invalid downlink subframe.
