Abstract
In one aspect of this disclosure, a communication device sends first and second precoding reports to a network node by time multiplexing the first and second precoding reports onto a reporting channel in accordance with a multiplexing ratio. The first and second precoding reports comprise first and second precoding recommendations, respectively, and correspond to the first and second dimensions of an antenna array used for transmitting to the communication device. Among other advantages, multiplexing of the first and second reports enables the communication device to reuse a reporting channel and at least some of the underlying reporting protocols or signaling arrangements to report multi-dimensional precoding information. The corresponding network node uses its knowledge of the multiplexing ratio to differentiate between the first and second reports. Moreover, the involved multiplexing ratio may be adapted, either by the network or the communication device, in view of changing operating scenarios.
