Abstract: Described is an apparatus of a User Equipment (UE) operable to communicate with an Evolved Node-B (eNB) on a wireless network. The apparatus may comprise a first circuitry and a second circuitry. The first circuitry may be operable to process a Downlink (DL) transmission carrying one or more Phase Tracking Reference Signal (PT-RSes). The second circuitry may be operable to generate an Uplink (UL) transmission carrying a Layer Indicator (LI) based at least on a number of PT-RS Antenna Ports (APs) associated with the PT-RSes.

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: 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.
