Abstract: Embodiments are presented herein of apparatuses, systems, and methods for a user equipment device (UE) to transmit an indication of a link failure on a secondary cell. The indication may be transmitted on resources selected based on one or more conditions. One or more priority rules may be used to resolve collisions. The UE may further make an assumption of a beam or beams to use for communications with the secondary cell following the link failure and prior to receiving an indication from the network of a selected beam.

Abstract: A device may wirelessly transmit a physical RACH, and a first message on a physical uplink shared channel (PUSCH), in a first step of a 2-step random access channel (RACH) procedure. The device may receive a second message on a physical downlink shared channel in response to successful detection of the first message, in a second step of the 2-step RACH procedure. When detection of the first message is unsuccessful, the device may be instructed to fall back to a 4-step RACH procedure. The device may be configured with one or more first message transmit opportunities (PO), one of which may include one or more PUSCH resource units (PRUs). Some of the communication parameters of the device may be configured to be common for each PO, while other communication parameters may be configured per PRU. Respective new Radio Network Temporary ID values may be defined for the first message and second message.

Abstract: Apparatuses, systems, and methods for providing downlink control for multi-TRP transmission. A cellular base station may provide a downlink control information transmission to a wireless device scheduling downlink transmissions to the wireless device from multiple transmission reception points. The downlink control information may include information that can be used by the wireless device to determine any or all of physical resource block bundling sizes, frequency domain resource allocations, modulation and coding schemes, redundancy versions, phase tracking reference signal configurations, and any of various other possible types of configuration information for the downlink transmissions. The wireless device may receive the downlink transmissions from the plurality of transmission reception points in accordance with the downlink control information.
