AI Technical Summary

Problems solved by technology

[0008] However, due to the large number of channel types, the processing scenarios are more complex, and the same subframe may contain multiple information such as CQI, ACK, SR, SRS, DMRS, and different data processing methods are required for different channel types; and , when dealing with a large amount of data, the multiplexing of resources and the processing time for reading and writing storage will be very long. If resources are not allocated reasonably, data will be lost due to conflicts in reading and writing.
Therefore, if the channels are not properly arranged in timing, data will be lost due to timing conflicts and other reasons during the transmission of the uplink channel, and resources such as hardware processing time, area, and power consumption will be wasted.
