  • Patent number: 12028198
    Abstract: An apparatus and system to compensate for phase noise in a 5G or 6G DFT-S-OFDM signal are described. An access port (AP)-specific orthogonal cover code (OCC) is applied to phase tracking reference signal (PTRS) symbols in each of a plurality of PTRS groups. The PTRS group are inserted between data symbols to form a data vector prior to perform transform precoding on the data vector and transmission to a UE. The UE extracts the PTRS symbols from different PTRS APs using the OCC specific to each AP. After extraction, the phase noise for each PTRS group is estimated and used to compensate the data symbols associated with the PTRS group.

  • Publication number: 20240214942
    Abstract: A computer-readable storage medium stores instructions to configure a UE for power scaling in uplink data transmissions in a 5G NR and beyond wireless network, and to cause the UE to perform operations including decoding RRC signaling received from a base station. The RRC signaling includes a power scaling factor. The power scaling factor indicates a transmission mode for uplink full power transmission. A linear output power value is determined for a maximum output power associated with the UE. The linear output power value is scaled using the power scaling factor to generate a scaled linear output power value. A PUSCH power control output is determined based on the scaled linear output power value. The operations further include causing the uplink full power transmission of uplink data using the PUSCH. The uplink full power transmission has transmit power based on the PUSCH power control output.
