  • Publication number: 20210112449
    Abstract: The disclosure includes a method at a device configured to process both wireless data traffic and Ethernet data traffic into a wireless communication, comprising determining, at a compressor, whether an acknowledgement (ACK) signal is received from a decompressor in response to transmitting, over a wireless communication link, a context creation message for a context identification (ID) associated with a flow of incoming Ethernet data traffic; refraining from transmitting, by the compressor to the decompressor over the wireless communication link, a compressed packet corresponding to the flow based on a first determination that the ACK signal is not received from the decompressor; and transmitting, by the compressor to the decompressor over the wireless communication link, the compressed packet corresponding to the flow based on a second determination that the ACK signal is received from the decompressor.

  • Patent number: 10932287
    Abstract: Methods, systems, and devices for dynamic monitoring and scheduling in retransmission are described for wireless communications. For example, a receiving device may receive a data transmission in a first receiver bandwidth, determine that a data packet of the data transmission was unsuccessfully decoded, switch to a second receiver bandwidth that is wider than the first receiver bandwidth or narrower than the first receiver bandwidth (e.g., based on determining that the data packet was unsuccessfully decoded), and receive a retransmission of the data packet in the second receiver bandwidth. In another example, a transmitting device may schedule a data transmission according to a first receiver bandwidth, receive an indication that a data packet of the data transmission was unsuccessfully decoded, and schedule a retransmission of the data packet according to a second receiver bandwidth that is wider than the first receiver bandwidth or narrower than the first receiver bandwidth.

  • Publication number: 20210044936
    Abstract: This disclosure provides methods, devices, and systems for processing uplink broadcast or multicast (“broadcast/multicast”) packets from a user equipment (UE) and distributing the broadcast/multicast packets to other UEs in a network. In some aspects, a UE may receive, from a base station, a downlink packet comprising broadcast or multicast (broadcast/multicast) Ethernet data for a protocol data unit (PDU) session of the UE with a data network (DN) associated with the base station, determining whether the downlink packet corresponds to an uplink packet previously transmitted to the base station by the UE, discarding the downlink packet for the PDU session based on determining that the UE previously transmitted the corresponding uplink packet comprising the broadcast/multicast Ethernet data for the PDU session to the base station, and processing the downlink packet for the PDU session based on determining that the UE did not previously transmit the corresponding uplink packet.

  • Publication number: 20210029705
    Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive control signaling configuring the UE with a set of frequency resources and a semi-persistent resource allocation indicating a semi-persistent resource occasion on each frequency resource of the set. The UE may monitor semi-persistent resource occasions on each of the set of frequency resources for a copy of a data transmission. If the UE receives and decodes the data transmission from at least one of the semi-persistent resource occasions, the UE may transmit an acknowledgement message on a frequency resource of the set. Additionally, the UE may refrain from transmitting a feedback message on the other frequency resources of the set. If the UE does not receive and successfully decode the data transmission from any of the semi-persistent resource occasions, the UE may transmit a negative acknowledgement message on one of the set of frequency resources.

  • Patent number: 10904905
    Abstract: Generally, the described techniques provide for a core network signaling to a base station a delay budget configuration that indicates a determined latency for communications between a core network, base station, and a user equipment (UE). In some cases, the core network may determine a first variable delay budget between the core network and a base station based on capability information associated with the wireless communications system. The core network may transmit the delay budget configuration to the base station, where the delay budget configuration may include the first delay budget. The base station may be able to determine a delay between the UE and the base station based on the delay budget configuration. Using the delay budget configuration, the base station may then schedule communications with the UE.

  • Patent number: 10903945
    Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a downlink data communication. The UE may determine a processing time for the downlink data communication based at least in part on at least one of: whether the downlink data communication was scheduled via preconfigured scheduling or via a downlink grant received in a downlink control channel, or whether the downlink data communication is an initial transmission or a retransmission. The UE may transmit acknowledgement or negative acknowledgement (ACK/NACK) feedback, corresponding to the downlink data communication, using a timing indicated by the processing time. Numerous other aspects are provided.

  • Patent number: 10904812
    Abstract: The present disclosure generally relates to techniques to increase reliability of communications within a network during a low reliability period. The network may include a user equipment (UE) communicatively coupled with one or more transmit/receive points (TRPs), with the communications between the UE and the one more TRPs requiring a reliability above a first reliability threshold. A processor of a network entity may identify a low reliability period which occurs when the reliability of the communications is determined to be below a second reliability threshold. The processor may cause the network to perform one or more remedial actions to increase the reliability during the low reliability period.
