Abstract:
1. A method in a first network radio entity for improving predictability of inter-cell interference in a wireless communication system, which first network radio entity is located in a first cell, wherein the prediction of the interference is made prior to transmission of data by at least one neighboring network radio entity located in a neighboring cell, the interference being generated by transmission of data from the first network radio entity to one or more receiving network radio entities located in said first cell, the method comprising: receiving an amount of data to be transmitted; estimating an amount of frequency resources needed to transmit data waiting to be transmitted, including the received amount of data; determining a resource limitation condition based on the estimated amount of frequency resources and at least one time limit, wherein said resource limitation condition prolongs a time needed to transmit the data waiting to be transmitted by at least one transmission time interval as compared to the time needed to transmit the data waiting to be transmitted using a maximum amount of frequency resources available per scheduling occasion; scheduling the data waiting to be transmitted while applying the resource limitation condition, so that the data waiting to be transmitted is scheduled for transmission in scheduling occasions within a scheduling time interval that extends over at least two scheduling occasions, the scheduling time interval depending on the resource limitation condition and on the estimated amount of frequency resources; and transmitting the data waiting to be transmitted on the estimated amount of frequency resources so that a respective portion of the estimated amount of frequency resources is used for transmitting a respective portion of the data waiting to be transmitted in each scheduling occasion over which the scheduling time interval extends.
