Abstract:
1. A method of wireless communication, comprising: receiving from a base station, a primary scheduling grant comprising a first traffic to pilot power ratio; transmitting a primary pilot channel and an enhanced primary data channel on a first virtual antenna of a multiple input multiple output (MIMO) uplink transmission, wherein a ratio between the power of the enhanced primary data channel and the power of the primary pilot channel corresponds to the first traffic to pilot power ratio; determining a size of a packet transmitted on the enhanced primary data channel in accordance with the first traffic to pilot power ratio by looking up a transport block size that corresponds to the first traffic to pilot power ratio; determining a reference power level corresponding to a secondary pilot channel; determining a rank of the transmission; transmitting an enhanced secondary data channel on a second virtual antenna of the MIMO uplink transmission based on the determined rank; and transmitting the secondary pilot channel on the second virtual antenna at a boosted power level relative to the reference power level, wherein a difference between the reference power level and the boosted power level is determined in accordance with the size of a packet transmitted on the enhanced primary data channel, wherein a ratio between the power of the enhanced secondary data channel and the power of the secondary pilot channel corresponds to the same first traffic to pilot power ratio, and wherein the first virtual antenna and the second virtual antenna utilize the same carrier frequency.
