Techniques for multi-cluster uplink transmissions

A method of wireless communications, comprising:

• receiving, by a user equipment (UE), one or more rate matching parameters;
• determining, by the UE, that the UE is not scheduled to transmit uplink signals in one or more sounding reference signal (SRS) resources based on the received one or more rate matching parameters;
• determining, by the UE, whether an uplink signal is an orthogonal frequency division multiplexing with cyclic prefix (CP-OFDM) signal or a discrete Fourier transform spread OFDM (DFT-S-OFDM) signal;
• determining, by the UE, a number of clusters that can be used by the UE for uplink transmissions based on the determination of the uplink signal being a CP-OFDM signal or a DFT-S-OFDM signal, wherein the number of clusters is different for the uplink signal being a CP-OFDM signal or a DFT-S-OFDM signal;
• and
• transmitting, by the UE, an uplink signal based on the determinations.

An apparatus for wireless communications, comprising:

• a receiver configured to receive signals;
• a transmitter configured to transmit signals;
• a memory configured to store instructions;
• and
• at least one processor communicatively coupled with the receiver, the transmitter, and the memory, wherein the at least one processor is configured to execute the instructions to:
• receive, via the receiver, information of one or more sounding reference signal (SRS) patterns;
• generate one or more rate matching parameters based on the information;
• determine whether an uplink signal is an orthogonal frequency division multiplexing with cyclic prefix (CP-OFDM) signal or a discrete Fourier transform spread OFDM (DFT-S-OFDM) signal;
• determine a number of clusters that can be used by the UE for uplink transmissions based on the determination of the uplink signal being a CP-OFDM signal or a DFT-S-OFDM signal, wherein the number of clusters is different for the uplink signal being a CP-OFDM signal or a DFT-S-OFDM signal;
• and
• transmit, via the transmitter, the uplink signal based on the generated one or more rate matching parameters.
