Abstract
Precoders are provided for multi-panel uplink (UL) transmission. A codebook may support asymmetric multi-panel UL transmission or super UL transmission where new radio (NR) and long-term evolution (LTE) transmissions may be provided through different antenna panels of a user equipment (UE). Sounding reference signal (SRS) enhancement provides support for multi-panel transmission. The UE transmits an indication of a UE capability based on an antenna structure comprising multiple antenna panels of the UE. Further, the UE determines, at the UE, one or more precoders to use for UL transmissions based at least in part on the UE capability, wherein the one or more precoders include a polarization co-phasing factor, an antenna panel co-phasing factor, and a combining weight for antennas for a same polarization. Additionally, the UE transmits, from the multiple antenna panels, the UL transmissions using the one or more precoders.
