    Abstract: Some embodiments of this disclosure include apparatuses and methods for reporting channel state information (CSI) for multiple spatial layers. The apparatuses and methods can include at least: determining, by a user equipment (UE), a precoding matrix indicator (PMI) for a set of precoding matrixes, wherein the PMI is determined based on a combination of digital Fourier transformation (DFT) spatial domain (SD) vectors, or based on DFT-based frequencydomain (FD) compression; and transmitting, by the UE, the PMI to a next-generation NodeB (gNB).

    Abstract: An approach is described for an access node configured for ultra-reliable and low latency (URLLC) transmission using multi-transmission reception point (TRP) to a UE. The access node includes processor circuitry and radio front end circuitry. The processor circuitry is configured to allocate resource blocks into a first portion and a second portion based on a resource indication value (RIV), a length of contiguously allocated resource blocks (LRBS) and a fraction. The radio front end circuitry is configured to transmit the first portion to the UE via a first transmission reception point (TRP1), and transmit the second portion to the UE via a second transmission reception point (TRP2).

    Abstract: Disclosed herein are system, method, and computer program product embodiments for performing beam selection. An embodiment operates by receiving, from a base station, a request for a report for at least one uplink beam. In response, the embodiment generates the report for the at least one uplink beam. The report for the at least one uplink beam can include an indication that a resource corresponding to the at least one uplink beam is available for uplink beam indication. The resource can be a Synchronization Signal Block (SSB) resource or a Channel State Information Reference Signal (CSI-RS) resource. The embodiment transmits the report for the at least one uplink beam to the base station. The embodiment then receives, from the base station, an indication that the at least one uplink beam is selectable for uplink transmission based on the report for the uplink beam.

    Abstract: Some embodiments of this disclosure include systems, apparatuses, methods, and computer-readable media for use in a wireless network for beam failure recovery (BFR). For example, some embodiments are directed to a user equipment (UE). The UE includes radio front end circuitry and processor circuitry coupled to the radio front end circuitry. The processor circuitry can be configured to receive, using the radio front end circuitry, one or more reference signals. The processor circuitry can be further configured to, in response to determining that a beam failure occurred for the one or more reference signals, determine a contention-free (CF) physical random access channel (PRACH) resource for a beam failure recovery (BFR) request. The processor circuitry can be further configured to transmit, using the radio front circuitry, the BFR request using the determined CF PRACH resource.

    Abstract: Systems, apparatuses, methods, and computer-readable media are provided for a user equipment (UE) in a wireless communication system using an unlicensed spectrum. The UE includes a processor circuitry and radio front end circuitry coupled with the processor circuitry. The processor circuitry is configured to determine UE processing time for a first physical downlink shared channel (PDSCH) transmission and a second PDSCH transmission, and an additional processing time corresponding to the first and the second PDSCH transmissions. The processor circuitry is configured to process a hybrid automatic repeat and request acknowledgement (HARQ-ACK) assessment information for inclusion in a subframe on a physical uplink control channel (PUCCH) following the UE processing time and the additional processing time. The radio front end circuitry is configured to receive the first and the second PDSCH transmissions from a base station, and transmit the HARQ-ACK assessment information on the PUCCH to the base station.

    Abstract: Disclosed are systems and methods of selecting physical downlink control channel (PDCCH) candidates for non-coherent joint transmission (NC-JT) in a wireless network. For instance, first and second sets of ControlResourceSet and SearchSpace parameters can be configured for a UE. The first and second sets of ControlResourceSet and SearchSpace parameters are configured on a first downlink (DL) component carrier to enable NC-JT. A control channel element (CCE) limit can be determined for the first and second sets of ControlResourceSet and SearchSpace parameters. One or more PDCCH candidates can then be selected for the first and second sets of ControlResourceSet and SearchSpace parameters based at least in part on the determined CCE limits. NC-JT communication including at least a first communication from a first transmission and reception point (TRP), and a second communication from a second TRP can then be received.

    Abstract: Systems, apparatuses, methods, and computer-readable media are provided for framework of layer 1 signal-to-interference plus noise ratio (L1-SINR) measurement and reporting based on channel measurement and interference measurement. The channel measurement is performed on a first set of reference signal (RS) resources, and the interference measurement is performed on a second set of RS resources. Each of the second set of RS resources is mapped to each of the first set of RS resources. The L1-SINR is determined from a first RS resource of the first set of RS resources and a second RS resource of the send set of RS resources, where the first RS resource is mapped to the second RS resource. A message including the L1-SINR is generated and transmitted to the access node.
