Abstract:
1. A method of transmitting data and reference signals, comprising: transmitting a resource block allocated to a first communication device, the resource block including a plurality of resource elements, each resource element corresponding to a modulation symbol; transmitting at least one reference symbol associated with the resource block and dedicated to the first communication device in a resource block allocated to a second communication device; further comprising transmitting a plurality of OFDM reference symbols dedicated to the first communication device in a plurality of resource blocks allocated to other communication devices so that the OFDM reference symbols encompass the resource block allocated to the first communication device in the time-frequency domain; and transmitting OFDM data symbols dedicated to the first communication device outside the resource block allocated to the first communication device, but within the region of the time-frequency domain encompassed by the OFDM reference symbols.
