  • Patent number: 10341933
    Abstract: A method and corresponding system for controlling whether a UE is served by a relay base station, based on consideration of the maximum-supported MCS of the relay base station's associated UE-relay. The method could apply where the UE is already served by the relay base station, in which case the question could be whether the UE continues being served by the relay base station or rather hands over to another base station. Or the method could apply where the UE is not yet being served by the relay base station, in which case the question could be whether the UE should initially attach with or hand over to the relay base station. Further, the method could be carried out by the UE and/or by a base station or other network entity.

  • 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: 10264596
    Abstract: A method and system to help manage a wireless client device's (WCD's) network connection with a core network gateway, where the WCD provides wireless backhaul connectivity to the core network for a relay base station with which the WCD communicates over a communication interface. The WCD detects passage of a threshold period of absence of communication on the communication interface between the WCD and the relay base station, and upon detecting that threshold period of absence of communication on that communication interface, the WCD releases its network connection with the core network gateway. Further, the WCD dynamically sets the threshold inactivity period for this purpose based on history of communications with which the relay base station has served one or more other WCDs.

  • Patent number: 10172029
    Abstract: A method and system for a base station to manage air interface communications with a wireless client device (WCD) served by the base station, taking into account whether the WCD is a relay-WCD that provides wireless backhaul connectivity for a relay base station. The base station will determine whether the served WCD is a relay-WCD, and based on a determination that the served WCD is a relay-WCD, the base station will responsively invoke a process to help expedite air interface communications with the served WCD, in an effort to reduce the total delay resulting from the wireless relay arrangement. In particular, based on the served WCD being a relay-WCD, and perhaps based on the relay-WCD facilitating a threshold extent of delay-sensitive communication, the base station will invoke transmission time interval (TTI) bundling, to help expedite the air interface communications between the base station and the relay-WCD.

  • Patent number: 10117133
    Abstract: A relay node is enabled to transmit, to an end-user wireless device, any data packets remaining in a buffer associated with the end-user wireless device, prior to executing a handover of the end-user wireless device. Upon initiating a handover, the relay node adjusts a scheduling operation to use a lowest-possible modulating coding scheme (MCS) in order to transmit the remaining buffered data to the end-user wireless device. Moreover, the scheduling operation is adjusted to ignore any subsequent channel quality indicator (CQI) reports from the end-user wireless device, thereby ensuring that the end-user wireless device has a higher chance of receiving the data. When the buffer is empty, the handover is executed.

  • Patent number: 10098039
    Abstract: Disclosed are methods and systems for setting a timeout period. In particular, a BS may have data storage defining a buffer. Also, the BS may be configured to (i) provide an air interface through which the BS serves UEs, (ii) buffer data packets destined to individual UEs, and (iii) apply a buffer timeout process according to which the BS drops a data packet from the buffer in response to that data packet being in the buffer for a timeout period. As such, the BS may make a determination that a served UE is a relay-UE that provides wireless backhaul connectivity for a relay-BS, and may set the timeout period based on the determination. When the BS then applies the buffer timeout process, the BS drops a data packet from the buffer in response to that data packet being in the buffer for the timeout period set based on the determination.
