  • Patent number: 11356566
    Abstract: Methods and apparatus for managing quality of service for video streaming, in which a Policy and Charging Rules Function (PCRF) in a Policy Charging Control (PCC) architecture of a telecommunications system receives from a Policy Control Enforcement Function (PCEF) a notification indicating that a video service has started for streaming video content to a user equipment (UE). A first Quality of Service (QoS) setting for streaming the video service to the UE is determined. First QoS setting data identifying the first QoS setting is transmitted to the PCEF. The PCEF transmits a further notification to the PCRF indicating that a particular stage has been reached. The PCRF receives the notification from the PCEF. In response to the further notification, a second QoS setting specifying a lower QoS than the first QoS setting for streaming the video service after the particular stage is determined. The PCRF identifies the second QoS setting to the PCEF.

  • Patent number: 11356213
    Abstract: Transmitters consider the size of a gap segment adjacent to at least one negatively acknowledged (NACKed) Radio Link Control (RLC) Service Data Unit (SDU) when considering when and/or how to concatenate one or more NACKed SDU segments for retransmission. Depending on which RLC SDU segment(s) is/are NACKed, e.g., considering the size of NACKed segments in relation to Protocol Data Unit (PDU) header size(s) needed, the transmitter implements a single RLC SDU retransmission or multiple RLC SDU segment retransmissions. In so doing, the solution presented herein not only defines how such transmissions occur, but also provides improved efficiency when retransmitting such NACKed SDU segments.

  • Patent number: 11356231
    Abstract: Short Control Channel Elements (SCCE) to Short Resource Element Groups (SREG) mapping for Short Physical Downlink Control Channel (SPDCCH) is provided. A User Equipment (UE) receives a communication from a base station; determines a mapping between one or more SCCE and corresponding SREG; and processes the communication based on the mapping. A base station determines a mapping between one or more SCCE and corresponding SREG for a communication to a UE and transmits a communication to the UE based on the mapping. In this way, the localized and distributed SCCE to SREG mapping for CRS-based SPDCCH is defined. Also, the SCCE to SREG mapping for 2 and 3 OFDM symbols DMRS-based SPDCCH is defined. For DMRS-based SPDCCH, a distributed configuration at SCCE level is defined. This may improve latency and can improve the average throughput of a communications system. Radio resource efficiency could be positively impacted by latency reductions.
