    Abstract: Aspects of beam specific scrambling of reference and data signals are disclosed. In an example, a user equipment (UE) receives a plurality of beams from a base station and determines payloads of a first control signal of a first beam of the plurality of beams and a second control signal of a second beam of the plurality of beams are a same payload. The UE also compares signal quality characteristics of the first control signal the second control signal when the payloads are the same payload and selects a better quality beam from the first beam and the second beam for decoding a data signal of the better quality beam in response to the comparison. The UE also decodes the data signal of the better quality beam.

    Abstract: Aspects of the present disclosure provide techniques to improve reliability and robustness for millimeter wave (mmW) systems in fifth generation (5G) wireless communications technology (also referred to as new radio (NR)). Specifically, the present disclosure provides techniques to allow the base station to group a plurality of mmW beams for communication with the user equipment (UE) such that the selected beam(s) for communication are independent and uncorrelated. The selection of beams ensure macro-diversity in that the joint blocking probability of the selected beam(s) may be minimized and the susceptibility to blockage is reduced in comparison to the current systems.

    Abstract: The present disclosure relates to transmitting and receiving improved quality reports using different transmission states. A base station may transmit to a user equipment (UE) a channel comprising multiple beams, wherein the beams include different Transmission Configuration Indicator (TCI) states. The UE can then perform beam quality measurements for the multiple beams. The beam quality measurements can include different channel quality indicator (CQI) measurements and can be performed using the same or different spatial filters. The UE can then determine a combined beam quality report for the different beams and transmit the report to the base station. The beam quality report can also comprise a comparison of, the difference between, or the average of, the different CQI measurements. The UE can also receive a configuration of filtering coefficients from the base station, wherein the beam quality report comprises filtered CQI information.

    Abstract: This disclosure provides systems, devices, apparatus, and methods, including computer programs encoded on storage media, for tracking channel variations via a model-based representation of the channel. A first network entity may receive from a second network entity or transmit to the second network entity, a model configuration indicative of a model condition of a channel between the first network entity and the second network entity. The model configuration may be associated with one or more initial parameters. The first network entity may receive a reference signal from the second network entity to measure a condition of the channel between the first network entity and the second network entity, and transmit, to the second network entity, one or more updated parameters for the model configuration based on a measurement of the condition of the channel in comparison to the model condition of the channel based on the model configuration.

    Abstract: Aspects of the present disclosure relate to wireless communications, and more particularly, to cell recovery techniques. One example method generally includes receiving, on a first cell, an indication that one or more channel measurements are to be reported for a second cell for which beam failure is detected; transmitting a first message triggering reporting of at least one preferred beam for communicating on the second cell, the first cell being different from the second cell, wherein the first message is transmitted in response to the indication that the one or more channel measurements are to be reported; receiving a report indicating the at least one preferred beam; and configuring a transmission configuration state in accordance with the at least one preferred beam for communicating on the second cell.

    Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from a base station, configuration information for a physical downlink control channel (PDCCH) associated with single frequency network (SFN) transmissions and PDCCH repetitions, wherein the configuration information indicates a first control resource set (CORESET) and a second CORESET, wherein the first CORESET is associated with a first transmission configuration indicator (TCI) state and the second CORESET is associated with a second TCI state. The UE may receive, from the base station and based at least in part on the reception of the configuration information, at least one of one or more SFN PDCCH messages or one or more PDCCH repetitions. Numerous other aspects are described.
