  • Patent number: 11025545
    Abstract: Embodiments herein describe branch statements for a segment routing (SR) list that are inserted into a packet header for use when performing Service function chaining (SFC). For example, the branch statement may be embedded within a SR list and includes a serverless function ID and two different segment IDs (SIDs). When reaching a network node assigned to perform the serverless function, the node uses the function ID to determine the appropriate serverless function to use when evaluating the packet and then uses the results of that function to determine which segment to use when forwarding the packet. Thus, rather than forming a linear chain, the branch statement permits the SR list to form different routes (depending on the results of the serverless function) as part of SFC.

  • Patent number: 11012209
    Abstract: Provided is a wireless communication user equipment that wirelessly communicates. The wireless communication user equipment includes a communication module; and a processor configured to control the communication module. The processor is configured to receive a demodulation reference signal (DM-RS) of data channel and receive the data channel based on the DM-RS of the data channel, wherein a time-frequency resource mapped to the DM-RS is predetermined. When the time-frequency resource mapped to the transmission of the DM-RS of the data channel overlaps with the time-frequency resource mapped to a different purpose from the transmission of the DM-RS, the processor is configured not to receive the DM-RS in a resource element (RE) overlapping with the time-frequency resource mapped to the different purpose in the time-frequency resource mapped to the transmission of the DM-RS. The DM-RS is a reference signal specific to the wireless communication device.

  • Patent number: 10986644
    Abstract: Aspects of the present disclosure provide for beam management in wireless communication systems. In some examples, beam angle information (e.g., angles of arrival/departure) may be utilized to select one or more serving downlink beams for communication between a scheduling entity and a scheduled entity. The beam angle information may further be utilized to facilitate additional operations within a backhaul network, such as wireless node locating, obstacle locating, system mapping within the network topology, beam determination and beam sweeping configuration, and mobility management among wireless nodes of a backhaul network. In other examples, aperiodic uplink beam measurements may be triggered based on downlink beam measurement reports and/or in response to a request from a scheduled entity.
