Abstract
Improved methods, systems, devices, or apparatuses support header compression for reduced bandwidth wireless devices prior to an initial transmission that includes a real-time data payload. A data flow containing real-time multimedia data may be initiated between a UE and a base station. In order to enhance the likelihood of meeting data flow timing constraints, compression context may be established prior to a first transmission of a packet with a real-time data payload. The one or more initial transmissions may include a small payload, that is smaller than typical real-time data payloads, may be used to establish compression context for the data flow. When a packet with a real-time payload is to be transmitted, the transmission may use header compression and be transmitted in less time than a transmission without header compression.
