    IPC: H04L47/36

    Abstract: The described technology is generally directed towards selecting, by user equipment, a selected maximum transmission unit (MTU) packet size for wireless data transfer based on radio signal conditions. In one aspect, reference signal received power (RSRP) and reference signal received quality (RSRQ) are used to select the MTU packet size, e.g., by using RSRP and RSRQ as indices to a lookup table of predetermined MTU packet sizes, such as previously determined by field testing. In general, smaller MTU packet sizes are used with poorer quality radio signal conditions. The selected MTU packet size may be increased or decreased based on actual performance data and/or based on changed radio signal conditions, such as for a subsequent data transfer session. The user equipment may comprise a Cat-M device that transfers data related to Machine-Type Communications (MTC)/Machine to Machine (M2M) communications.

    Abstract: Determining to initiate a user equipment handover event based on a signal-to-interference-plus-noise ratio value is disclosed. The disclosed subject matter can employ the signal-to-interference-plus-noise ratio value in lieu of a reference signal receive power value. In an aspect, a handover based on the signal-to-interference-plus-noise ratio value can generally be determined faster and with greater reliability than basing the handover on the reference signal receive power value. In an aspect, some embodiments can substitute a determined uplink signal-to-interference-plus-noise ratio value for a downlink signal-to-interference-plus-noise ratio value. In some embodiments, a predicted signal-to-interference-plus-noise ratio value can be determined based on historical channel characteristics, hysterical wireless network environment features, or other historical data. A predicted signal-to-interference-plus-noise ratio value can be validated to a determined current signal-to-interference-plus-noise ratio value, permitting a validated predicted value to be employed until a next validation event.
