  • Patent number: 11677600
    Abstract: In wireless communications for a 20 megahertz (MHz) channel bandwidth, a first device may determine a high efficiency long training field (HE-LTF) mode. The first device may generate an HE-LTF symbol by using a portion or an entirety of an HE-LTF sequence corresponding to the channel bandwidth and HE-LTF mode. The first device may transmit, in the channel bandwidth, a high efficiency physical layer protocol data unit (HE PPDU) that includes the HE-LTF symbol. A second device may receive, in the 20 MHz channel bandwidth, a downlink HE PPDU that includes an HE-LTF symbol. The second device may obtain, from the HE-LTF symbol, a portion or an entirety of an HE-LTF sequence corresponding to the channel bandwidth and an HE-LTF mode of the HE-LTF symbol. The downlink HE PPDU may be the HE PPDU from the first device. Other methods, apparatus, and computer-readable media are also disclosed.

  • Patent number: 11602003
    Abstract: A wireless communication network serves a User Equipment (UE) over multiple User Plane Function Groups (UPFGs). In the wireless communication network, a Session Management Function (SMF) receives UPFG performance metrics from the wireless communication network. The SMF identifies a Packet Data Flow Group (PDFG) for the UE. The SMF responsively selects one of the UPFGs for the PDFG based on the UPFG performance metrics. The selected UPFG comprises at least three User Plane Functions (UPFs) and the PDFG comprises at least two Packet Data Flows (PDFs). The SMF transfers network signaling to the selected UPFG to deliver the PDFG to the UE. The selected UPFG receives the network signaling and responsively exchanges user data for the UE to deliver the PDFG.

  • Patent number: 11595176
    Abstract: Methods, systems, and devices for wireless communications are described in which beamforming may be configured at a user equipment (UE) for narrowband communications. The UE may be a narrowband UE that may provide an indication to a base station that the UE is capable of performing beamforming communication for a unicast channel transmission. Such an indication may be provided in response to the UE receiving a non-beamformed broadcast channel transmission from the base station via a first carrier. The base station may receive the indication and configure the UE with a beamformed narrowband communications scheme. Such a beamformed formed narrowband communications scheme may be used for narrowband downlink shared channel communications, narrowband downlink control channel communications, or combinations thereof. In some cases, beamformed communications may be configured on a different carrier than the first carrier. The base station and UE may then communicate using beamformed transmissions.
