  • Patent number: 10462834
    Abstract: Systems, methods, and apparatuses for improved traffic management in wireless communications are disclosed. Aspects of the present disclosure provide real-time assessments to a network by leveraging measurement reports from user equipment (UE). In some aspects, the network utilizes channel quality indicator (CQI) information from each of a serving cell and a neighboring cell to identify UE capabilities and expected UE performance prior to either offloading or rerouting traffic to the UE. Accordingly, based on the received CQI information and a greater understanding of the anticipated UE performance, the radio network controller (RNC) may be better equipped to determine whether to offload and/or reroute the traffic scheduled for transmission to the UE via the neighboring cell or the serving cell.

  • Patent number: 10412014
    Abstract: The disclosure provides for a user equipment (UE) detecting an indication of an application-specific latency reduction triggering condition that may trigger switching of a communication state of the UE. For example, the UE may be in an initial state. The UE may transition into a different state that is associated with lower latency for data transfer. In an aspect, the UE may trigger the indication for latency reduction even when the network-configured criteria for the indication has not yet been met. The UE may trigger an application-specific latency reduction triggering condition during the startup of an application, which triggers a resource request message even before the network-configured threshold value for generating such resource request messages is satisfied. The resource request message may cause the network to command the UE to transition to a state that has a latency less than that in the current state.

  • Patent number: 10349466
    Abstract: Methods, systems, and devices for wireless communication are described. A wireless device may receive data during an active duration of a discontinuous reception (DRX) configuration. The wireless device may be configured such that it identifies a transmission opportunity following the reception opportunity, so that it may transmit a response to the received data during the transmission opportunity. In another example, the wireless device may transmit data during an active duration of a discontinuous transmission (DTX) configuration. The device may be configured such that it identifies a reception opportunity following the DTX active duration, so that a response may be received during the reception opportunity. The presence of a transmission opportunity following a DRX active duration, or a reception opportunity following a DTX active duration may depend on the service type and priority of the data being communicated, and may be either semi-statically configured or dynamically signaled.

  • Patent number: 10219312
    Abstract: Techniques are described for wireless communication. A base station may indicate to a UE, in a pre-wakeup period, whether the base station will transmit a grant to the UE. The pre-wakeup period may occur at the beginning of a DRX cycle. The base station may transmit an indication of a grant to the UE, and the base station may indicate a time period during which the UE may wake up to receive the grant. The indication may include scheduling information for the grant. The UE may select a DRX mode based on a configuration received from the base station, a traffic pattern, or scheduling history. The UE may monitor for the grant, and receive the grant. In other examples, the UE or the base station may identify that the grant was not received, and may reset a DRX cycle based on the identification.

  • Publication number: 20180279181
    Abstract: Methods, systems, and devices for wireless communication are described for a beam-aware handover procedure for multi-beam access systems. A source base station may determine that a handover request is to be sent to a target base station in preparation for handover of a user equipment (UE) from the source base station to the target base station, and transmit the handover request to the target base station with an indication of whether the handover is to be delayed. Alternatively or in addition to, either the target base station or the source base station may generate and transmit a time expiration indicator. The indication of whether the handover is to be delayed or the time expiration indicator may allow either the target base station or the UE to determine whether access parameters for the UE are valid.
