Determining an order of modulation for each transport block based on initial channel state information
View Patent ↗A system for updating channel state information may include a base station wirelessly sending a reference signal to a user device. The bases station may receive channel state information based on the reference signal. Then, the bases station may determine a number of transport blocks to enable, a number of layers to use, and an order of modulation for each transport block based on the channel state information. The bases station may then receive subsequent channel state information from the user device using the determined parameters.
1. A system comprising:
a transmitter;
a receiver to wirelessly receive a reference signal over one or more wireless channels from a base station;
a memory storing instructions;
a processor to execute the instructions to:
calculate initial channel state information of the one or more wireless channels by analyzing the reference signal; and
receive a determined a number of transport blocks to enable, based on the initial channel state information, a determined number of layers to use, and a determined order of modulation for each transport block wherein the transmitter is to wirelessly send subsequent channel state information to the base station using the determined number of transport blocks, the determined number of layers, and the determined order of modulation for each transport block; and
wherein analyzing the reference signal comprises comparing first characteristics of the reference signal as sent initially to second characteristics of the reference signal after it has been received.
2. The system of claim 1 further comprising a display.
3. The system of claim 1 , wherein the subsequent channel state information is sent over a physical uplink shared channel during an aperiodic channel state information-only transmission.
