Abstract: Systems, apparatuses, methods, and computer-readable media are provided for user equipment (UE) idle mode operations. In embodiments, a UE wakes up more than once during a Discontinuous Reception (DRX) cycle. Inter-frequency measurement requirements may be relaxed based on DRX cycle length. Some embodiments include radiofrequency (RF) circuitry warm-up overhead reduction by on-duration separation with RF circuitry switching pattern adaption. Some embodiments include and RF circuitry warm-up overhead reduction by adaptive synchronization signal block (SSB) reference symbol down-selection. Other embodiments may be described and/or claimed.

Abstract: Herein described are apparatuses, systems, and methods for measurement and reporting of channel state information within wireless network systems. In embodiments, an apparatus for a user equipment (UE) may include memory to store a rank indicator (RI), a precoding matrix index (PMI), and a channel quality indicator (CQI) of channel state information (CSI) for the UE. The apparatus may further include circuitry to concatenate the RI, the PMI, and the CQI to produce a concatenated CSI element, generate a CSI report that includes the concatenated CSI element, and cause the CSI report to be transmitted to a base station within a single slot. Other embodiments may be described and/or claimed.

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.

Abstract: Described is an apparatus of a User Equipment (UE). The apparatus may comprise a first circuitry and a second circuitry. The first circuitry may be operable to process a message carrying an indicator to indicate a selection of a Sounding Reference Signal (SRS) resource set, wherein the message is received from a gNB. The second circuitry may be operable to generate an SRS transmission, based on the indicator. The apparatus may comprise an interface to send the SRS transmission to a transmission circuitry.

Abstract: Described is an apparatus of an Evolved Node-B (eNB). The apparatus may comprise a first circuitry and a second circuitry. The first circuitry may be operable to determine a first Sounding Reference Signal (SRS) sequence and a second SRS sequence. The second circuitry may be operable to process a first Uplink (UL) transmission from the first UE incorporating the first SRS sequence over a first set of subcarrier frequencies. The second circuitry may also be operable to process a second UL transmission from the second UE incorporating the second SRS sequence over a second set of subcarrier frequencies. The second SRS sequence may comprise at least a first block that overlaps the first set of subcarrier frequencies and a second block that does not overlap the first set of subcarrier frequencies.
