发明名称 CSI Reporting for a Set of CSI-RS Resources
摘要 A method implemented by a wireless terminal of reporting channel state information to a wireless communication network is disclosed. The wireless terminal receives reference symbols on a set of channel state information reference symbol (CSI-RS) resources, and determines a common transmission rank for the set of CSI-RS resources, based on the reference symbols received on a subset of those CSI-RS resources. The terminal then generates CSI feedback as a function of the common transmission rank, and transmits the CSI feedback to the communication network. The CSI feedback may include the common transmission rank itself, or may include different transmission ranks for different CSI-RS resources each determined as a function of the common transmission rank. A complementary method in which a network node uses such a CSI feedback to perform rank adaptation for the set of CSI-RS resources is also disclosed.

主权项 1. A method implemented by a wireless terminal for reporting channel state information (CSI) to a wireless communication network, comprising: receiving reference symbols on a set of channel state information reference symbol (CSI-RS) resources; determining a common transmission rank for the set of CSI-RS resources, based on the reference symbols received on a subset of those CSI-RS resources; generating CSI feedback as a function of the common transmission rank; and transmitting the CSI feedback to the communication network.
