  • Patent number: 10383101
    Abstract: Link adaptation for an uplink channel is dynamically performed based on changes in uplink resources in the wireless network, the changes based on frame configuration. If the ratio of uplink to downlink subframes in the new frame configuration is smaller, the throughput is increased by increasing a modulation and coding scheme of the uplink channel, and transmit power of wireless devices. If the ratio of uplink to downlink subframes is increased in the new frame configuration, the throughput is decreased, and the wireless device is instructed to transmit using reduced transmit power.

  • Patent number: 10333649
    Abstract: One or more packets to be transmitted to or from a user equipment (UE) device are determined to have a particular packet length, e.g., based on a vocoder to be used for a voice over Long Term Evolution (VoLTE) call. An initial modulation and coding scheme (MCS) is selected for transmission of the packets based on channel conditions. The initial MCS is replaced by an alternative MCS having a lower efficiency than the initial MCS in response to a determination that the alternative MCS would require the same number of resource blocks to transmit a packet having the particular packet length as the initial MCS. One or more resource blocks are allocated for transmission of the one or more packets having the particular packet length using the alternative MCS. Indications of the allocated one or more resource blocks and the alternative MCS are transmitted to the UE.

  • Patent number: 10327267
    Abstract: As IMS-based sessions are established for UEs served by a relay base station, the IMS platform will signal to a core network to request setup of bearers for carrying traffic of the IMS-based sessions and will identify the relay base station serving the UEs. Based on this IMS signaling messages identifying the relay base station serving the UEs for which the bearers are being set up, the core network will track a count of such bearers established for UEs served by the relay base station. And upon detecting that the tracked count reaches a threshold level, the core network will trigger adjustment of a maximum bit rate and/or other QoS attribute of a relay bearer established for providing aggregate wireless backhaul connectivity for the relay base station.

  • Patent number: 10320519
    Abstract: Methods and systems for controlling service by a base station when the base station is serving both a first UE without carrier aggregation and a plurality of second UEs with carrier aggregation. As a basis for invoking carrier aggregation service for the first UE, the base station selects one of the second UEs to transition from being served by the base station with carrier aggregation to being served by the base station without carrier aggregation. The base station makes such a selection based at least in part on a modulation and coding scheme that the base station uses to serve the selected one of the second UEs. The base station transitions from serving the selected second UE with carrier aggregation to serving the selected second UE without carrier aggregation. And the base station transitions from serving the first UE without carrier aggregation to serving the first UE with carrier aggregation.
