Flexible transmission of messages in a wireless communication system with multiple transmit antennas
Devices and methods for transmitting information in resource blocks between a base station and one or more communication devices are disclosed. In each resource block (RB) used for a data or control channel transmission, a plurality of non-overlapping regions of resource elements (REs) are defined. Each region is associated with one or multiple unique reference symbols (RSs), and may be further associated with one or more antenna ports. When user equipment (UE) demodulates the information it receives in a particular region of an RB, it uses the RS and/or antenna port associated with that region. The RS and/or antenna port information may be used, for example, to estimate a channel of the communication network or to demodulate and decode the data contained within the associated regions.
