Patent ID: 8705496

Claim:
A method of controlling transmission of dedicated pilots in a wireless communication system, comprising: determining a Modulation and Coding Scheme (MCS) level for a data channel; determining amount of resources required for sending dedicated pilots in inverse proportion to the MCS level; determining that the dedicated pilots will be sent, if the MCS level is less than or equal to a predetermined threshold; and determining to map the dedicated pilots to the determined amount of resources being part of the resources allocated to the data channel, when it is determined that the dedicated pilots will be sent; generating a pilot channel signal including basic pilots mapped to resources allocated to a pilot channel, a control channel signal including control information mapped to resources allocated to a control channel, and a data channel signal including the dedicated pilots mapped to the determined amount of resources being part of resources allocated to the data channel and data mapped to remaining resources allocated to the data channel; and multiplexing the pilot channel signal, the control channel signal, and the data channel signal and sending the multiplexed signal in the mapped resources.
