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： A relay node for a wireless network is configured for transmissions on the basis of a radio frame with a plurality of subframes. The relay node includes a first relay path and a second relay path. The first relay path is configured to receive, in a first subframe of the subframes, first unicast transmission signals, to decode the first unicast transmission signals to obtain unicast data, and to forward the decoded unicast data by sending second unicast transmission signals in a second subframe of the subframes. The second relay path is configured to receive, in a third subframe of the subframes, multicast transmission signals, to amplify the received multicast transmission signals, and to send the amplified multicast transmission signals in the third subframe. The relay node may switch between the first relay path and the second relay path in order to implement a hybrid Decode-and-Forward and Amplify-and-Forward relaying operation.
