Contention-based communication

摘要

For an example embodiment, a method for a communication device operating in a synchronous communication system is described. The method includes performing a listen-before-talk (LBT) procedure prior to the start of a downlink subframe of a synchronous frame and determining if a transmission from another communication device of another communication system is detected during the LBT procedure. In the case that a transmission is detected during the LBT procedure, the communication device refrains from transmitting during the downlink subframe. In the case that a transmission is not detected during the LBT procedure, the communication device transmits during the downlink subframe.

1. A method for use in a base station comprising:
detecting a transmission from an interferer that is not in communication with the base station; determining at least one characteristic of the transmission; determining a type of the interferer based on the at least one characteristic; selecting a minimum extended quiet period (EQP) duration from a plurality of different minimum EQP durations based on the determined type of the interferer; and refraining from transmitting for at least the selected minimum EQP duration, wherein the selected minimum EQP duration is greater than a transmission duration of a maximum packet length of the determined type of the interferer.
