Abstract: Disclosed herein are system, method, and computer program product embodiments for implementing multiple receive (multi-Rx) chain downlink (DL) reception when the receive timing difference (RTD) at a user equipment (UE) from multiple transmission and reception points (TRPs) is greater than the cyclic prefix (CP). An embodiment operates by configuring a first base station (BS) to transmit a first data and a second BS to transmit a second data simultaneously to a user equipment (UE) during a first symbol period, where the first data from the first BS is received by the UE using a first receive beam and the second data from the second BS is received by the UE using a second receive beam. The embodiment also configures the first BS to transmit a reference signal (RS) to the UE during a second symbol period that is subsequent to the first symbol period. The embodiment then determines a scheduling restriction applied to the second BS during a plurality of symbol periods, wherein the plurality of symbol periods include the second symbol period. Finally, the embodiment provides the scheduling restriction the second BS.

Abstract: Embodiments are disclosed for enhanced layer 3 (L3) measurement reporting that supports L3 measurement assisted group-based beam reporting (GBBR). Some embodiments include a user equipment (UE) that can receive a first reference signal from a network at a first angle of arrival (AoA), and receive a second reference signal from the network at a second AoA. The UE can perform L3 measurements on the first reference signal and the second reference signal, and generate and transmit to the network, an enhanced L3 measurement report that includes L3 measurements as well as: a corresponding identity of an antenna panel of the UE; bits that correlate an antenna panel with a respective L3 measurements, or an implication that the L3 measurements in the enhanced L3 measurement report correspond to different antenna panels. The UE can receive simultaneous downlink transmissions from the network that are based on the enhanced L3 measurement report.

Abstract: Aspects are described for a user equipment (UE) comprising two or more transceivers configured to enable wireless communication with a first base station, and a processor communicatively coupled to the two or more transceivers. The processor is configured to measure a first reference signal and a second reference signal during a measuring period to determine a first measuring result of the first reference signal and a second measuring result of the second reference signal. The processor is further configured to generate one or more reports that include the first measuring result and the second measuring result, wherein the one or more reports indicate that the first measuring result is associated with the second measuring result in time. The processor is further configured to transmit the one or more reports to the first base station.
