摘要： A backhaul link is established between a base station and a relay that assists the base station in communicating with a mobile device over an access link established between the relay and the mobile device. The channel response of the backhaul link is determined by estimating first and second parts of the backhaul link channel response, the second part changing faster than the first part. The first part of the backhaul link channel response is estimated by calculating an average of the backhaul link channel response over a predetermined period at the relay and the second part is estimated by calculating variation in the backhaul link channel response over the predetermined period at the relay. Quantized versions of the first and second parts of the backhaul link channel response are transmitted from the relay to the base station over the backhaul link.

摘要： With respect to cooperative signal communication between a mobile terminal (200) and a plurality of access nodes (100-1, 100-2), a combined signal quality value is calculated on the basis of a first individual signal quality value (Q1 ) of a communication link between a first access node (100-1 ), e.g. a serving base station, and the terminal (200), and a second individual signal quality value (Q2) of a second communication link between a second access node (100-2), e.g. a supporting base station, and the terminal (200). On the basis of the combined signal quality value, a transmission parameter (50) for future cooperative transmissions is adapted. The transmission parameter (50) may be a modulation scheme, a coding scheme, a transmit power, or a resource allocation.
