Abstract
According to embodiments herein a method is provided and performed by a network node for handling communication in a wireless communication network. The network node transmits a pair of CSI-RS ports associated with different polarizations through different groups of power amplifiers, applying TD-OCC to maintain orthogonal on same resource elements. With repetition of OFDM symbols by each CSI-RS port, coverage of the network node can be extended.
Claims21
A method performed in a wireless device, comprising:
- obtaining a CSI-RS configuration indicating that a pair of CSI-RS ports of a transmitter being associated with different antenna polarizations are multiplexed with different TD-OCCs;
- and
- receiving, according to the CSI-RS configuration, the pair of CSI-RS ports being multiplexed with different TD-OCCs that share same resource elements.
