  • Patent number: 10291364
    Abstract: A communications device and method, in which data is communicated via a wireless access interface to a destination communications device with a device-to-device communication procedure. The communications device encodes the data, as data units, for transmission to the destination communications device with a repeat request-type protocol, the encoding providing an indication whether the data has been received correctly. The communications device transmits the encoded data units to the destination communications device, and receives an acknowledgement ACK message that one of the encoded data units has been correctly received by the destination communications device, or a negative acknowledgement NACK message that the encoded data units were not received correctly by the destination communications device.

  • Patent number: 10277439
    Abstract: Methods, systems, and devices for wireless communication are described that may perform dual stage channel interleaving in which code blocks are interleaved at the code block level and at a symbol level. The interleaved code block data may provide time diversity for the code block data, and the interleaved symbol data may provide frequency diversity for the code block data, thus helping to mitigate narrowband and/or bursty interference. The interleaving within the code block and interleaving within the symbols, in some examples, may allow pipelined implementation of decoding of the code blocks at the receiver, for faster processing. In some cases, systematic data and parity data may be interleaved within the code block data to provide a uniform distribution of the systematic data in time within the code block.

  • Patent number: 10277515
    Abstract: A core network (CN) may establish and distribute a quality of service (QoS) policy across a wireless communication system, e.g., by sending QoS policy information to an access network and to user equipment. The QoS policy may be implemented with respect to data network (DN) sessions as well as data sessions. For each DN session or data session, the QoS policy may be applied by explicit or implicit request, and data sessions may in some examples utilize pre-authorized QoS policies without the need to request the QoS.

  • Patent number: 10271375
    Abstract: Systems and methods are described for reducing latency for a group call. A group call random access (RACH) preamble selected from a subset of predetermined random access preambles associated with a group call may be received at an access node from a first wireless device, wherein the group call random access preamble indicates to the access node that a group call is to be established. A RACH response may be transmitted to the first wireless device comprising an uplink resource grant associated with a group call setup, wherein the uplink resource grant is greater than uplink resource grant associated with a default RACH response. And the group call may be established by communicating with the first wireless device based on the uplink resource grant associated with group call setup, wherein the group call is established between at least the first wireless device and a second wireless device.

  • Patent number: 10251091
    Abstract: Embodiments of the present application disclose a traffic offloading method and apparatus. The method includes: calculating, by a first network node, a first packet loss rate of a first forwarding tunnel in a preset period; when the first packet loss rate is higher than a first preset threshold, reducing a rated bandwidth of the first forwarding tunnel by a first preset bandwidth, so as to obtain a first available bandwidth; and when traffic forwarded over the first forwarding tunnel exceeds the first available bandwidth, offloading excess to-be-forwarded traffic to the second data link for forwarding. Because the first available bandwidth is less than an original available bandwidth of the first forwarding tunnel, the to-be-forwarded traffic exceeds the first available bandwidth at an earlier time, traffic is offloaded by the first network node in advance, and a serious packet loss is less likely to occur before traffic offloading.
