摘要： In a wireless communication system, a base station adaptively schedule CQI reports form mobile stations. By adaptively prioritizing the CQI report from the mobile station against the uplink traffic and control data, the CQI reporting rate avoids unnecessary overhead in the uplink while maintaining good performance. The CQI reports are requested in response to a calculated weighting factor which is based on channel coherence time that can be estimated by the base station. The adaptivity in the CQI reporting allows achieving an optimal tradeoff between uplink traffic data and downlink control feedback signaling.

摘要： In a mobile communication network, a radio node and related method for reducing a signal-to-noise-and-interference ratio (SINR) requirement for a transmission in a scheduling interval. The node estimates a frequency resource utilization in the scheduling interval and compares the estimated utilization with a first threshold. When the estimated utilization is equal to or below the first threshold, the node increases the frequency resource utilization for the transmission, and adjusts a link adaptation for the transmission based on the increased frequency resource utilization. Optionally, the node may decrease the transmit power for the scheduling interval based on the adjusted link adaptation.

摘要： A low power RBS and a method therein for scheduling downlink transmission to a UE are provided. The low power RBS is associated to at least one macro RBS and the low power RBS is configured to provide radio coverage in a cell of a heterogeneous cellular communication network for scheduling downlink transmissions to a UE connected to the low power RBS. The method comprises receiving (210) a measurement report comprising a channel quality measurement from the UE and adjusting (220) a current SINR value based on the received measurement report for a period of an Almost Bland Subframe, ABS, of the macro RBS. The method further comprises determining (230) downlink transmission parameters based on the adjusted SINR value, and scheduling (240) a downlink transmission to the UE in a subframe of the low power RBS coinciding with an ABS of the macro RBS using the determined downlink transmission parameters.
