CHANNEL ESTIMATION REFERENCE SIGNALS FOR PRE-EQUALIZATION

This abstract first appeared for US patent application 20250097079 titled 'CHANNEL ESTIMATION REFERENCE SIGNALS FOR PRE-EQUALIZATION

Original Abstract Submitted

methods, systems, and devices that support channel estimation reference signals for pre-equalization are described. in some examples, channel state information (csi) for a link between a user equipment (ue) and another wireless device may be acquired by the ue based on samples of a downlink reference signal transmitted from the ue to the wireless device. specifically, the wireless device (e.g., an extended reality (xr) device) may obtain samples of the downlink reference signal (e.g., a channel estimation reference signal) and report or indicate (e.g., transmit) the samples to the ue via an uplink transmission. for example, the reference signals may be sampled at the wireless device side, and csi may be obtained using the samples signaled back to the ue by the wireless device. the ue may perform channel estimation based on the received samples, which may enable transmit pre-equalization of signals sent to the wireless device.
