SYMBOL TRANSMISSION METHOD AND COMMUNICATIONS APPARATUS - A simplified explanation of the abstract

This abstract first appeared for US patent application 18540826 titled 'SYMBOL TRANSMISSION METHOD AND COMMUNICATIONS APPARATUS

Simplified Explanation

The patent application describes a method for phase noise estimation in wireless communication systems using reference signals on multiple resource blocks. Here are the key points of the innovation:

• Transmit-side device determines frequency-domain positions of reference signals on multiple resource blocks.
• Reference signals are on consecutive frequency-domain resources within at least one resource block.
• Transmit-side device maps reference signals to symbols based on their frequency-domain positions.
• Mapped symbols are sent to a receive-side device for phase noise estimation.

Original Abstract Submitted

This application provides a method. The method may include: a transmit-side device determines frequency-domain positions of reference signals that are used for phase noise estimation and that are on a plurality of resource blocks, where there are a plurality of reference signals on at least one resource block in the plurality of resource blocks, the reference signals occupy consecutive frequency-domain resources on the at least one resource block, for example, occupy a plurality of consecutive subcarriers; the transmit-side device maps, based on the frequency-domain positions of the reference signals on the plurality of resource blocks, the reference signals to one or more symbols, and sends, to a receive-side device, the one or more symbols to which the reference signals are mapped; and the receive-side device performs phase noise estimation based on the reference signals.
