Aspects of the present disclosure relate to wireless communications, and more particularly, to techniques for mitigating interference caused by legacy reference signals from neighbor cells (e.g., LTE cell-specific reference signals) to non-legacy downlink transmissions in a serving cell (e.g., NR/5G PDSCH transmissions).

Interference mitigation of strong neighbor cell non-colliding CRS

Methods, systems, and devices for wireless communications are described. A user equipment (UE) may indicate, to a base station, a capability of the UE to use a channel measurement resource for both a joint transmission hypothesis and a single transmission hypothesis. The UE may receive, based on indicating the capability of the UE, a configuration message indicating a first channel measurement resource that is associated with a first transmission configuration indicator state and that is configured for a first joint transmission hypothesis. The UE may obtain a channel measurement for both the first joint transmission hypothesis and a first single transmission hypothesis using the first channel measurement resource based on the configuration message.

Resource sharing between transmission hypotheses

A user equipment (UE) receives, from a base station, a message including at least one reporting configuration and resource configuration for a number of channel state information-interference measurement (CSI-IM) resource patterns associated with a first radio access technology (RAT). Each of the configured CSI-IM resource patterns corresponds to a time and frequency location in a resource block of a neighbor cell associated with a second RAT. The UE transmits one or more CSI reports based on the reporting configuration(s) and the resource configuration(s).

First radio access technology (RAT) channel state feedback (CSF) to increase accuracy of interference estimates from second RAT neighbor cells with dynamic spectrum sharing (DSS)

The disclosure relates in some aspects to enabling a user terminal (UT) to obtain information about nearby cells and any beams generated by nearby cells. For example, a network can send a neighbor cell list to UTs, where the list identifies the cells in that neighborhood and provides information about any beams generated by those cells. Thus, a UT can learn the neighboring beams/cells that the UT can reselect to if the current beam/cell becomes weak. In some aspects, the UE can learn the attitude (e.g., pitch, roll, yaw, or any combination thereof) profile of neighboring satellites as well as the pointing angles and the ON-OFF schedules of their beams. In some aspects, the UT can learn a start angle and a span for a satellite and use this information to identify a satellite the UT can reselect to if the current beam/cell becomes weak.
