Abstract

A method, an apparatus, and a computer program product for wireless communication are provided in connection with selection of a communication mode based on traffic type information. In one example, a network entity (e.g., a WiFi router, Picocell, Fentocell, an eNB, etc.) is equipped to obtain traffic type information for content to be transmitted by a network entity, determine a communication mode to use for transmission of the content based on the traffic type information, and transmit the content using the determined communication mode. In an aspect, the traffic type information may indicate that the content is a best effort traffic type, a latency sensitive traffic type, or no traffic type is available.
