Method and network entity for scheduling radio resources in mobile communication networks
Abstract:
A method and radio network entity for scheduling resources comprising: selecting the user for which the scheduling metric calculated based on CQI reports is a main maximum in a certain frequency subband and checking whether there is another subband in which the selected user has a calculated scheduling metric value higher than the main maximum. If so, secondary maxima of scheduling metrics for said user and others in another different subband are searched and compared with the previous calculated maximum. According to the result of this comparison, each user is assigned to at least one frequency subband, up to K subbands which can be adjacent or not depending upon the configuration of the network entity in uplink and downlink (e.g., supporting LTE). Scheduling of both time and frequency resources is optimized and simultaneously the throughput of users in a cell is maximized.
