  • Patent number: 11039432
    Abstract: In a control channel resource transmission method, user equipment (UE) obtains a configuration parameter in a candidate control channel set according to a preset protocol and/or higher-layer signaling sent by a base station, where the higher-layer signaling is used to notify the configuration parameter. The UE determines an antenna port according to the obtained configuration parameter, and then receives, through the antenna port, a control channel or a control channel element sent by the base station. The base station determines the antenna port according to the same configuration parameter as that of the user equipment, and sends, by using the antenna port, the control channel or the control channel element to the user equipment.

  • Publication number: 20210096901
    Abstract: A shared memory may be employed for use with a front end (e.g., a guest virtual machine (GVM) component) and a back end (e.g., native driver, physical virtual machine (PVM) component, hardware, etc.) of a virtualization system to allow the front end to influence (e.g., control) the occurrence of the virtual interrupt request (IRQ) forwarding from the back end. The shared memory may include one or more flags or one or more lists to allow the front end to control the behavior of the back end virtual IRQ forwarding logic without causing the back end to stop its existing processes. Thus, the front end may multiple numerous input/output (IO) requests, but the front end may only check the completion of some of the requests (e.g., based on work items written into the shared memory, by the front end, for back end processing and back end IRQ forwarding).
