Abstract
A method for communicating in a wireless communications system includes generating a channel state information (CSI) process information element (IE) including a CSI process identifier, a non-zero padded CSI-reference signal (CSI-RS) identifier, an interference measurement resource (IMR) identifier, and channel quality indicator (CQI) report configuration information. The method also includes transmitting the CSI process IE.
Claims25
A method for communicating in a wireless communications system, the method comprising:
