Abstract:
1. A method of sending signaling in a wireless communication network, comprising: determining, by a processor, a set of subcarriers reserved for sending a reduce interference request to a base station, wherein each subcarrier in the reserved set of subcarriers is associated with a different priority level; determining, by the processor, a priority level of the reduce interference request; selecting, by the processor, a subcarrier in the reserved set of subcarriers based on the priority level of the reduce interference request, wherein the priority level associated with the selected subcarrier corresponds to the priority level of the reduce interference request; and sending, by a transmitter, the reduce interference request on the selected subcarrier in multiple symbol periods to the base station, wherein the priority level of the selected subcarrier conveys the priority level of the reduce interference request.
