Abstract:
Techniques for reporting timing information to facilitate data transmission on a downlink are described. A user equipment (UE) may receive signals from a plurality of cells available for data transmission to the UE. Each cell may have a different propagation delay to the UE. The UE may determine timing information based on the received signals and may report the timing information to one or more of the cells. The timing information may include a receive time of each cell at the UE. The UE may receive a data transmission from at least one cell, which can be selected from the plurality of cells, based on the timing information. The at least one cell may provide a coordinated or a non-coordinated data transmission. A coordinated transmission mode may be determined based on the timing information and can include, for example, a joint transmission, a coordinated beamforming, or a coordinated silencing.
