  • Multi-RAT Wireless Communication
    Publication number: 20220286960
    Abstract: A wireless communication device uses a first radio access technology (RAT) module and a second RAT module to perform functions relating to a first RAT and a second RAT, respectively. The wireless communication device uses the second RAT module, while the first RAT module is in a reduced power state, to perform a portion of a random access procedure to access the first RAT. The wireless communication device then wakes the first RAT module from the reduced power state and uses the first RAT module to complete the random access procedure to access the first RAT.

  • Method and apparatus for configuring beamforming operations in a wireless communication network
    Patent number: 11418972
    Abstract: A wireless communication device transmits beam sweeping information that indicates a beam sweeping property of the device, and a network node in an associated wireless communication network configures transmission or reception beamforming with respect to the device at one or more Transmission/Reception in the network, based on the beamforming property. Among the various advantages flowing from configuring network-side beamforming for the device in view of the beamforming property, the network need not configure its beamforming operations according to worst-case or minimum-capability assumptions for the device, and, instead tailors its transmission or reception beamforming in dependence on the beamforming property of the device.

    Abstract: Exemplary embodiments include methods for a user equipment (UE) to receive a wake-up signal (WUS) via downlink control information (DCI) transmitted by a network node in a radio access network (RAN). Such methods include receiving a physical downlink control channel (PDCCH) from the network node, and processing the received PDCCH to determine if it includes a DCI carrying a WUS targeted to the UE. The processing can include determining if a payload portion of the DCI is based on a first function of an identifier associated with the UE (e.g., C-RNTI) or with a group of UEs (e.g., WUG-RNTI). The processing can also include determining if a cyclic redundancy check (CRC) portion of the DCI is based on a second function of the identifier.

    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.
