    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: 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 and a second circuitry. The first circuitry may be operable to determine a first parameter set and a second parameter set for establishing Physical Downlink Shared Channel (PDSCH) resources. The second circuitry may be operable to process a first part of a PDSCH transmission from a first set of Multiple Input Multiple Output (MIMO) layers corresponding with a first Multimedia. Broadcast Single Frequency Network (MBSFN) configuration based on the first parameter set. The second circuitry may also be operable to process a second part of the PDSCH transmission from a second set of MIMO layers corresponding with a second MBSFN configuration based on the second parameter set.

    Abstract: Disclosed herein are system, method, and computer program product embodiments for performing beam failure recovery. An embodiment operates by detecting a beam failure on a secondary cell (SCell). The embodiment transmits, to a base station, a beam failure recovery request (BFRQ) for the SCell over a primary cell (PCell). The embodiment transmits the BFRQ for the SCell over a Primary Uplink Control Chanel (PUCCH), a Physical Random Access Channel (PRACH), or a Primary Uplink Shared Channel (PUSCH) over the PCell. The embodiment can transmit a schedule request (SR) to allocate a PUSCH over the PCell. The embodiment receives, from the base station, a response for the BFRQ for the SCell over the SCell or the PCell. The embodiment then uses a new beam for the SCell based on the response for the BFRQ for the SCell.

    Abstract: Methods and apparatus are described for methods and apparatus for carrying out wireless communication using Long Term Evolution (LTE) in a frequency band with low peak-to-average-power. The approach includes precoding, in the frequency domain, a plurality of physical channel signals, followed by multiplexing, where the procoding is performed according to predetermined codes with a code length selected based on a length of an entire signal of the multiplexed precoded plurality of physical channel signals. In addition, the approach includes being configured to map the multiplexed precoded plurality of physical channel signals to subcarriers in the frequency band, as well to generate a time domain waveform based on the mapped signals.
