Abstract

A user equipment (UE) and associated method performs a voice call with a network, including exchanging voice packets, determines an uplink data transmission to be performed concurrently with the voice call and stores the uplink data transmission in a buffer. A base station and associated method performs a voice call with a UE, determines a downlink data transmission for the UE is to be performed concurrently with the voice call and stores the downlink data transmission in a buffer when the UE is a predetermined type. A UE and associated method associates with a first access point (AP), determines first performance characteristics of a connection with the first AP, determines second performance characteristics of a potential connection with a second AP, declares a radio link failure when the second performance characteristics exceed the first performance characteristics to trigger a handover procedure from the first AP to the second AP.
