  • Patent number: 11671913
    Abstract: Systems and methods allow access stations to save power when no user equipment (UE) devices require service from the access station. The access station may enter a low power-consumption mode (or “sleep mode”) when the access station is inactive. The access station transmits a beacon signal when in the low power-consumption mode to indicate to UE devices in a coverage area of the access station that the access station is in the low power-consumption mode. The access station receives a wake-up signal from a device and, in response, exits the low power-consumption mode.

  • Patent number: 11606781
    Abstract: Method and apparatus for configuring a triggering condition of a beam failure event and a communication system. The method includes: a network device configures a UE with one or more control channel monitoring groups, so that when the UE detects that all beams to which a monitoring group corresponds fail in transmission, the UE reports beam failure event of the monitoring group fails in transmission; wherein, each monitoring group corresponds to one or more pieces of downlink control information (DCI). By configuring regarding the triggering conditions of the beam failure events, detection and report of beam failure in more complex scenarios may be supported, such as a scenario where one piece of DCI is transmitted in multiple control resource sets, and a scenario where multiple pieces of DCI are transmitted in one control resource set, etc.

  • Publication number: 20220174533
    Abstract: A device may receive data indicating a required quality of service (QoS), and may receive radio access network (RAN) information associated with a RAN, wherein the RAN information is provided by a centralized unit (CU) of the RAN. The device may provide the RAN information to a multi-access edge computing (MEC) platform, and may receive, from the MEC platform, a QoS request that requests the required QoS. The device may provide the QoS request to the CU, and may receive a QoS response to the QoS request. The device may provide the QoS response to a policy control function (PCF) of a core network, and may receive an indication of approval of the QoS response from the PCF. The device may cause, based on receiving the indication of approval, the required QoS to be implemented by the MEC platform and network devices associated with the core network.
