Abstract: A method for improving distributed resource allocation in OFDMA based wireless communication networks such as WiMAX IEEE 802.16 for either fixed or mobile subscriber stations SSs is executed by neighbor Base Stations BSs serving the SSs. Each BS controls the allocation of respective permutation zones and radio resources encompassing different radio subchannels within each permutation zone. In this task the BS avails of RRM primitives and instances of a NCMS functionality promoting direct BS-to-BS communication, which can be exploited in a distributed RRM profile. A BS playing the role of RRC sends to Neighbor BSs a unique RRM Request for receiving event-driven Spare Capacity Reports. Among driving events, “Change of Radio Resources Allocation” is included. Neighbor BSs, at every allocation change is detected, send to the requester BS a Spare Capacity Report including a Bitmap indicating subchannels used for transmission in each Permutation Zone.

Abstract: A method of selecting suitable frequency bands for data transmission between a network node and a user equipment within a mobile communications network. A method selects suitable frequency bands for data transmission between a network node and user equipment within a mobile communications network. A scheduler on the network node side selects data transmission mode depending on the user equipment capability of receiving data from at least two frequency bands simultaneously. The scheduler preferably selects the data transmission mode in the following way: simultaneous data transmission over at least two frequency with or without splitting traffic data or data transmission over only one available frequency band. For data transmission, a radio frame structure (Big MAC element) is dynamically established in the so-called medium access control layer, shortened so-called MAC-layer, by using concurrent radio resources from other frequency bands or other radio access technologies.
