Patent ID: 11864218
Assignee: T-MOBILE USA, INC.
Field: Digital communication (Electrical engineering)
Classification: CPC H | IPC H

Claim 0:
1. A non-transitory computer-readable storage medium comprising instructions recorded thereon that, when executed by at least one data processor of a system of a wireless communication network, cause the system to perform a method of determining waveforms for uplink (UL) transmissions in a mobile device operating in the wireless communications network, the method comprising:
receiving signals identifying UL frequency resources scheduled to the mobile device for concurrent UL transmissions;
receiving signals identifying downlink (DL) frequency resources scheduled to the mobile device for DL transmissions; and,
automatically determining, based on the UL and DL frequency resources, a waveform for use by the mobile device for the concurrent UL transmissions,
wherein the determining is based on a frequency of an intermodulation distortion (IMD) product of two or more frequencies of the UL frequency resources,
wherein the mobile device is to use a Discrete Fourier Transform (DFT)-spread Orthogonal Frequency Division Multiplexing (OFDM) (DFT-s-OFDM) waveform for the concurrent UL transmissions when the frequency of the IMD product is within the DL frequency resources, and
wherein the mobile device can use a Cyclic Prefix (CP) OFDM (CP-OFDM) waveform for the concurrent UL transmissions when the frequency of the IMD product is not within the DL frequency resources.
