  • Patent number: 10158471
    Abstract: The embodiments of the present invention provide a demodulation reference signal processing method, a base station and a user equipment. A processing method includes: generating, by a base station, a DMRS corresponding to an E-PDCCH by using information that is available before a UE receives the E-PDCCH sent by the base station; and mapping, by the base station, the DMRS onto a time-and-frequency resource corresponding to a downlink control channel region and used for transmitting a reference signal, and sending the DMRS to the UE. In the technical solutions of the embodiments of the present invention, the base station and the UE no longer use an SCID for generating the DMRS, which solves the problem that the UE cannot obtain the SCID before receiving the E-PDCCH and cannot generate the DMRS, and further, cannot demodulate the E-PDCCH, and enables demodulation of the E-PDCCH.

  • Patent number: 10057855
    Abstract: Technology is discussed for supporting the incorporation of a Primary Synchronization Signal (PSS) and/or a Secondary Synchronization Signal (SSS) within in a New Carrier Type (NCT) for a Component Carrier (CC). Guidelines for incorporating the PSS and/or the SSS in the NCT are discovered, together with potential collisions with other signals that can be avoided for various scenarios. In some examples, various guidelines and potential collisions discovered herein, for various scenarios, inform approaches to incorporating the PSS and/or the SSS based on the positioning of the PSS and/or the SSS. In other examples, other signals, such as DeModulation Reference Symbols (DMRS) are reconfigured to allow incorporation of the PSS and the SSS.

  • Patent number: 10045016
    Abstract: A method of managing lip synchronization error in a multimedia content delivery network includes identifying a video packet and an audio packet associated with the video packet and determining a synchronization offset between the audio and video packets at a first monitoring point in the network. The audio and video packets are then detected at a second monitoring point in the network and a second synchronization offset is determined. When a delta between the first synchronization offset and the second synchronization offset exceeds a threshold, lip synchronization error information may be automatically recorded and/or reported to a service provider and corrective action may be taken if potential sources of the lip synchronization error are within the domain of the service provider. The video packet may be identified by a timestamp within the packet and the audio packet may be identified by audio data within the audio packet.

  • Patent number: 10004099
    Abstract: A method of extended DRX paging includes a base station that transmits extended DRX configuration information and a User Equipment (UE) receives the extended DRX configuration from the base station. The UE determines a first number of frames that are included in a hyper-frame based at least in part on the extended DRX configuration information and selects a hyper-frame number. The hyper-frame number is based at least in part on the extended DRX configuration information. The UE maintains a hyper-frame count and the hyper-frame count is incremented after each hyper-frame. The UE then goes into sleep mode and the UE determines a wake up time before a standard DRX cycle that occurs during the selected hyper-frame. The UE may also determine a first wake up time and a second wake up time based on the selected hyper-frame number and synchronization error between a first cell and a second cell.

  • Patent number: 9998979
    Abstract: Explicit congestion notification (ECN) bits that have traditionally been utilized in end to end congestion mitigation can be redefined to identify and compare congested and uncongested wireless accesses. Accordingly, mobile devices or other user equipment can leverage ECN data in order to make intelligent network selection, e.g., selecting a network with no congestion over one in a congested state. Accordingly, an application executing at the mobile device can send or receive data via the selected network that is selected based on ECN data.
