Abstract: Aspects of the disclosure relate to maintaining, defining, configuring and implementing a coverage enhancement mode defined for radio access network. A base station may maintain parameters that define multiple coverage enhancement modes in a lookup table and may select a first coverage enhancement mode from the two or more coverage enhancement modes for use with a first user equipment to accommodate use of one or more carrier frequencies, time or frequency duplexing mode, cell size, capabilities of the first user equipment or a channel measurements report of the first user equipment, and schedule a set of control and data channels to be used for communicating with the first user equipment using a first transmission scheme defined by first parameters associated with the first coverage enhancement mode. The set of control and data channels may include uplink control and data channels and downlink control and data channels.

Abstract: An apparatus receives a configuration for a phase tracking reference signal (PT-RS). The apparatus then determines at least one of a time density or a frequency density for the PT-RS based on inter-slot repetition of a transmission. The apparatus then receives or transmits the PT-RS based on the at least one of the time density or the frequency density determined based on the inter-slot repetition of the transmission.

Abstract: Wireless communications systems and methods related to multi-transmission-reception point (multi-TRP) precoding matrix indication (PMI) operations are provided. A user equipment (UE) receives a configuration indicating a precoder size parameter for a plurality of transmission-reception points (TRPs). The UE receives, from a first TRP of the plurality of TRPs, a first reference signal. The UE receives, from a second TRP of the plurality of TRPs, a second reference signal, the second TRP being different from first TRP. The UE transmits, to the first TRP or the second TRP, a channel state information (CSI) report including a first feedback component based on the first reference signal and a second feedback component based on the second reference signal, where a combined payload size of the first feedback component and the second feedback component is based on the precoder size parameter.

Abstract: Aspects relate to reporting channel state information (CSI) for a plurality of multiple transmission and reception points (TRPs) in a communication system. Downlink (DL) channels received from multiple TRPs are measured and a plurality of transmission hypotheses based on the measured DL channels from the multiple TRPs. The CSI is transmitted to a network in the communication system and includes a precoding matrix indicator (PMI) having at least a spatial domain basis matrix that is common to all of the transmission hypotheses and at least one coefficient matrix that is based on the spatial domain basis matrix.

Abstract: Methods, systems, and devices for wireless communications are described to support communication between a base station and a user equipment (UE) via multiple transmission reception points (TRPs). The base station may configure the UE to report a precoding matrix indicator (PMI) for various transmission modes, including one or more transmission modes for multiple TRPs. The UE may determine and report first PMI to the base station for each single TRP transmission mode, and the base station may use the first PMI to determine a precoding matrix for each TRP. The UE may determine and report partial PMI to the base station for the one or more multi-TRP transmission modes. The base station may use respective partial PMI to determine a precoding matrix for each multi-TRP transmission mode and may communicate with the UE using the determined precoding matrix or matrices.
