    Abstract: Devices and methods of using xSS are generally disclosed. A UE receives an xPSS with (Nrep) symbols each with a subcarrier spacing of K×a PSS subcarrier spacing and a duration of a PSS symbol/K. PSD subcarriers surround the xPSS and the ZC sequence is punctured to avoid transmission on a DC subcarrier. Guard subcarriers separate the xPSS and PSD when the ZC sequence is less than the occupied BW of the xPSS and at least one element in the ZC sequence is punctured for xPSS symbol generation otherwise. One or more xSSSs and xS-SCHs may follow the xPSS. The xSS may be omnidirectional, each having a same xPSS and different xSSS or xS-SCH or a different xPSS and same xSSS or xS-SCH or beamformed, each having different xPSSs and xSSSs or xS-SCHs or a same xPSS and different xSSS or xS-SCH.

    Abstract: Serving cell measurements at a reduced capability UE in idle mode in FRI includes identifying an eDRX cycle length associated with the reduced capability UE is longer than or equal to 20.48 s and shorter than or equal to 10, 485.76 s. The eDRX cycle length includes a DRX cycle length. A measurement period associated with a serving cell of the reduced capability UE is determined to occur within a single PTW of the eDRX cycle. The measurement period includes measurement samples to be performed within the single PTW. A length of the single PTW is determined based on a product of the DRX cycle length and a sample scaling factor associated with the measurement samples. The length of the single PTW comprises a multiple of 1.28. Serving cell measurements are performed during the single PTW. The serving cell measurements include each of the measurement samples associated with the measurement period.

    Abstract: Aspects herein relate to wireless devices, circuits, and methods for indicating, by a wireless device, to a wireless station, an ability to support semi-persistent (SP) measurement gap (MG) configuration; receiving, from the wireless station, a SP MG configuration; receiving, from the wireless station, a message to activate the SP MG configuration; performing, in response to receiving the message to activate the SP MG configuration, a target carrier frequency measurement, wherein the target carrier frequency measurement is performed in accordance with the activated SP MG configuration; receiving from the wireless station, a message to deactivate the SP MG configuration; and discontinuing, in response to receiving the message to deactivate the SP MG configuration, the performance of the target carrier frequency measurement. In other aspects, the wireless device may indicate, to the wireless station, an ability to support aperiodic (AP) MG configuration, which does not require explicit deactivation by the wireless station.

    Abstract: Apparatuses, systems, and methods for sidelink physical channel enhancements for unlicensed spectrum, e.g., in 5G NR systems and beyond. A UE may determine, for a contiguous resource block (RB) based sidelink physical channel transmission in SL-U, whether a sub-channel can be used for the sidelink physical channel transmission based on a condition associated with a number physical RBs (PRBs) configured for the sidelink physical channel. The UE may transmit, in response to determining that the condition is satisfied, the sidelink physical channel. The condition may be a total number of PRBs in a sub-channel not overlapping the guard band being greater than or equal to the number of PRBs configured for the sidelink physical channel or a portion of PRBs at a beginning of a sub-channel not overlapping with the guard band being greater than or equal to the number of PRBs configured for the sidelink physical channel
