    Abstract: Embodiments of a User Equipment (UE), Next Generation Node-B (gNB) and methods of communication are generally described herein. The UE may receive control signaling to configure transmission of: a first physical uplink control channel (PUCCH) that includes first uplink control information (UCI) of a first UCI type; and a second PUCCH that includes second UCI of a second UCI type. In some cases, if the transmissions of the first PUCCH and the second PUCCH would overlap in a number of slots, the UE may, if the first and second UCI types are not of the same priority: transmit, in the overlapping slots, the PUCCH that includes the UCI type of highest priority; and refrain from transmission in the overlapping slots, and without postponement of the transmission, of the PUCCH that includes the UCI type of lowest priority.

    Abstract: Described is an apparatus of a User Equipment (UE) operable to communicate with a fifth-generation Evolved Node-B (gNB) on a wireless network. The apparatus may comprise a first circuitry, a second circuitry, and a third circuitry. The first circuitry may be operable to detect a beam failure event. The second circuitry may be operable to generate a beam failure recovery request for transmission to the gNB, in response to the beam failure event. The third circuitry may be operable to monitor for Physical Downlink Control Channel (PDCCH) in a search space configured by the gNB, subsequent to a transmission of the beam failure recovery request.

    Abstract: The present disclosure provides systems and methods for mapping transmission configuration indication (TCI) states to demodulation reference signal (DMRS) ports groups in a wireless network. For instance, a TCI state to DMRS ports group mapping of a user equipment (UE) can be determined. Each DMRS port in a DMRS ports group shares a quasi-co-location (QCL) assumption. The TCI state to DMRS ports group mapping comprises multiple TCI state groups. The TCI state to DMRS ports group mapping corresponds each TCI state group to one or more DMRS ports groups. A TCI state group from the DMRS ports group mapping can be selected for the UE. Data indicative of the selected TCI state group and the corresponding one or more DMRS ports groups can be provided to the UE based at least in part on the TCI state group from the DMRS ports group mapping.

    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.

    Abstract: Systems, devices, and techniques for wireless communications are described. A described technique includes receiving, by a user equipment (UE) from one or more Transmission and Reception Points (TRPs), a physical downlink shared channel (PDSCH) transmission; determining, by the UE for a physical uplink control channel (PUCCH) carrying hybrid automatic repeat request-acknowledgement (HARQ-ACK), a TRP index in accordance with a control resource set (CORESET) scheduling the PDSCH transmission; and transmitting, by the UE via the PUCCH, HARQ-ACK information based on the receiving of the PDSCH transmission in accordance with the TRP index.

    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.
