Abstract: A method and network node for determining radio resources for allocation to a downlink control channel in a communication network are disclosed. According to one aspect, a method includes receiving, over a predetermined measurement period, a plurality of reports from a wireless device, each report being indicative of a channel quality within at least a subband of an available bandwidth of the communication network. The method further includes for each subband for which at least one report has been received, determining a variance of the channel quality and an average of the channel quality over the predetermined measurement period. The method further includes determining subbands having at least a variance of the channel quality less than a first threshold.

Abstract: A method and node for power efficient allocation of enhanced physical downlink control channel resources are disclosed. According one aspect, a method at a network node of allocating an enhanced control channel to a first wireless device is provided. The method includes determining a control channel subframe pattern for the first wireless device. The subframe pattern for the first wireless device includes at least an indication of a pattern of subframes during which the first wireless device is to monitor the enhanced control channel for downlink control information. The subframe pattern is based at least in part on enhanced control channel subframe utilization of other wireless devices. The method also includes transmitting the control channel subframe pattern to the first wireless device, and transmitting the downlink control channel information to the first wireless device over the enhanced control channel according to the enhanced control channel subframe pattern.

Abstract: Joint uplink processing by plural base stations includes sending, by a serving base station, a request for uplink resources of a second base station for receiving uplink data of a mobile station. The serving base station receives first uplink data from the mobile station, and the serving base station further receives (from the second base station) second uplink data of the mobile station received by the second base station using the uplink resources specified by the request.

Abstract: A scheduler performs per sub-band prioritization allocation of sub-bands to user terminals to generate a pre-allocation schedule. The prioritization is performed independently for each sub-band. The resulting pre-allocation schedule indicates the relative priorities of the user terminals for each sub-band taking into account the channel conditions and specific needs of the user terminals. Based on the pre-allocation schedule, the scheduler can more efficiently allocate the radio resources to the user terminals based on the channel conditions and the specific needs of the user terminals. The scheduling approach is suitable for parallel computing architectures. The use of a parallel computing architecture increases MIPS (million instructions per second) capacity and allows faster scheduling in order to meet stringent real-time constraints.
