    Abstract: Example HARQ-based transmission methods and apparatus are provided, to meet transmission requirements of different services. In one example method, a network device receives a QoS parameter that is of a service corresponding to a service request and that is delivered by a core network device. The network device determines, based on the QoS parameter of the service, a HARQ configuration parameter corresponding to the service, and notifies the HARQ configuration parameter to the terminal device. Therefore, when different services are transmitted between the network device and the terminal device, different HARQ configuration parameters are configured for different services, and data transmission and retransmission of a service are performed based on a configured HARQ configuration parameter, so that transmission requirements of different services can be met.

    Abstract: Disclosed are a data transmission method, device, and system, which are used for resolving the problem of large overhead if an existing manner of sending a public message periodically is used in an ultra-dense network. The method comprises: user equipment sends an uplink request message, the uplink request message being used for requesting for obtaining public information of a first access node in an area in which the user equipment is located; and the user equipment receives the public information sent by the first access node. Because an access node in an area in which user equipment is located does not need to broadcast and send public information periodically, the access node can send, based on an uplink request of the user equipment, the public information, thereby improving the resource utilization and reducing the energy consumption.

  • Patent number: 10564708
    Abstract: Described herein in various embodiments are techniques to better coordinate long wakeup events on a network processor that are due to radio or network activity with the long wakeups that are due to requests from an application processor. In one embodiment, power management logic can receive wake requests from system processes upon notice that one or more application processors are transitioning into a low power state. The power management logic can coalesce the wake requests based on a supplied margin and determine a wake timeframe in which the application processor may be opportunistically woken from the low power state. The power management logic can provide the wake timeframe for the application processor to a network processor in the system. The network processor can opportunistically cause an early wake of the application processor during the wake timeframe.

  • Patent number: 10512014
    Abstract: The present disclosure relates to a handover apparatus and method capable of avoiding in-device coexistence interference. In order to prevent handover failure due to in-device coexistence interference, an SeNB provides TDM information (including TDM pattern information or TDM activation information) to a UE during a handover procedure, and the UE performs the handover with a TeNB according to the provided TDM information. By the disclosure, the UE can perform ISM signal transmission/reception and LTE signal transmission/reception with the TeNB in a discriminated manner according to a particular TDM pattern, so as to prevent handover failure due to the in-UE coexistence interference.

  • Patent number: 10499422
    Abstract: A wireless communication apparatus is provided. The wireless communication apparatus is provided with: a control part performing repetitive transmission of a repetitive signal, that is, a signal that needs to be repeatedly transmitted, from a transmission part in the form of an electric wave; a reception part receiving an electric wave; and a signal collision determination part determining, on the basis of the electric wave received by the reception part while the repetitive signal is being transmitted by the control part, whether or not the repetitive signal transmitted from the transmission part is in collision with a signal transmitted by a different device. When the signal collision determination part has determined that the repetitive signal is in collision with another signal, the control part changes the transmission timing of the repetitive signal.

  • Patent number: 10476705
    Abstract: Adaptive windowing of insufficient cyclic prefix (CP) for joint minimization of intersymbol interference (ISI) and adjacent channel interference (ACI) is provided. The proposed subcarrier specific windowing scheme improves the signal-to-interference ratio (SIR) even when the cyclic prefix (CP) is insufficient. Average optimal window lengths depend only on the power density profiles (PDPs), and although instantaneous optimal window lengths depend on users' channel impulse responses (CIRs), fluctuation is little. Therefore, subcarrier specific windowing outperforms fixed windowing, even with outdated window lengths in the case of powerful interferers.
