Abstract
Mechanisms are provided for reporting process information for simultaneous multi-panel uplink (UL) transmissions. According to the embodiment of the invention, the first device sends the first capability information to the second device. The first capability information includes a list of UE capability value sets. Each set of UE capability values in the list defines an antenna arrangement of the first device and is characterized by a first number of transmit antenna ports. And the first device sends the second capability information to the second device. The second capability information comprises a group of sets of UE capability values, wherein the group of sets of UE capability values defines a plurality of antenna arrangements of the first device; and coherent information in the phase domain between transmission antenna ports of the plurality of antenna arrangements or between the plurality of antenna arrangements. In this manner, simultaneous UL transmissions based on a multi-antenna panel codebook using different antenna panels with different capabilities are enabled.
