    Abstract: Resource allocation is provided for an integrated access and backhaul (IAB) network, such as a distributed unit (DU) of an IAB. Methods and systems include configuring one or more resources to allocate time-domain or frequency domain availability/utilization. Configurations of resources can be aligned between one or more nodes such that resource availability of a first node can be coupled to resources of a second node. Allocated resources can include uplink, downlink, and flexible resources. Allocated resources can be indicated as not available, hard, or soft resource types. A configuration pattern can indicate a sequence of time-domain resource or frequency domain resource availability of a DU in the IAB network.

    Abstract: An approach is described for a method for a fifth generation (5G) wireless communication or a new radio (NR) system that includes the following steps. The method includes generating data samples associated with a sampling rate. The method further includes generating a waveform by populating a first slot and a second slot in a subframe of the waveform using the data samples, wherein slot durations of the first slot and the second slot in the subframe of the waveform equal respective durations of a first slot and a second slot in a subframe of a reference waveform to thereby align the first slot and the second slot in the subframe of the waveform with the respective first slot and second slot in the subframe of the reference waveform. The method further includes transmitting the waveform using front end circuitry, wherein the waveform is a single carrier waveform, and wherein the reference waveform is an orthogonal frequency division multiplexing (OFDM) waveform.

    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: Apparatuses, systems, and methods for multiplexing of PUCCH for beam failure recovery and other signals. A UE may determine a transmission dropping rule and a transmission power scaling rule for a PUCCH which is dedicatedly configured for secondary BFR transmission, such as a PUCCH-BFR, when it is multiplexed with BFR multiplexed with at least one other signal. The PUCCH-BFR and the at least one other signal may be multiplexed in a CC or in multiple CCs. The UE may determine a transmission dropping rule, e.g., so that UE can transmit an uplink signals with higher priority and drop the other uplink signal with lower priority to avoid beam collisions. The UE may determine a transmission power scaling rule, e.g., so the UE may scale transmission power within a CC and/or across CCs. The UE may multiplex the PUCCH-BFR with the at least one other signal according to the rules.
