  • Publication number: 20220166580
    Abstract: An approach is described for a method for a fifth generation (5G) wireless communication or a new radio (NR) system that includes the following steps. The method includes generating data samples associated with a sampling rate. The method further includes generating a waveform by populating a first slot and a second slot in a subframe of the waveform using the data samples, wherein slot durations of the first slot and the second slot in the subframe of the waveform equal respective durations of a first slot and a second slot in a subframe of a reference waveform to thereby align the first slot and the second slot in the subframe of the waveform with the respective first slot and second slot in the subframe of the reference waveform. The method further includes transmitting the waveform using front end circuitry, wherein the waveform is a single carrier waveform, and wherein the reference waveform is an orthogonal frequency division multiplexing (OFDM) waveform.

  • Publication number: 20220116911
    Abstract: Systems and methods of increasing paging opportunities when the unlicensed band is used are described. The gNB sends an RRC message that indicates multiple monitoring occasions in a paging occasion of a paging frame. The UE monitors a monitoring occasion of a PO to determine whether a PDCCH with a P-RNTI has been received in an unlicensed band. If such a PDCCH is received, the UE decodes PDSCH information in the PDCCH to determine whether the P-RNTI is a P-RNTI of the UE. If so, the UE avoids monitoring subsequent monitoring occasions of the PO. If the PDCCH does not contain a P-RNTI, the UE continues to monitor other monitoring occasions within the PO.

  • Publication number: 20220116252
    Abstract: For single carrier based waveform, Discrete Fourier Transform-spread-OFDM (DFT-s-OFDM) and single carrier with a frequency domain equalizer (SC-FDE) can be considered for both DL and UL. For OFDM based transmission scheme including DFT-s-OFDM, a cyclic prefix (CP) is inserted at the beginning of each block, where the last data symbols in a block is repeated as the CP. Typically, the length of CP exceeds the maximum expected delay spread in order to overcome the inter-symbol interference (ISI). For SC-FDE transmission scheme, a known sequence (guard interval (GI), unique word (UW), etc.) can be inserted at both the beginning and end of one block. Further, a linear equalizer in the frequency domain can be employed to reduce the receiver complexity. Compared to OFDM, SC-FDE transmission scheme can reduce Peak to Average Power Ratio (PAPR) and thus allow the use of less costly power amplifier.

  • Publication number: 20220116129
    Abstract: Some embodiments of this disclosure include apparatuses and methods for measuring and/or reporting UE-to-UE crosslink interference (CLI). In some embodiments, a communication network may use transmission reception points (TRPs) to facilitate communications for user equipment (UE). A first TRP may command a first UE to transmit a crosslink interference reference signal (CLI-RS) according to a particular time behavior. A second TRP may command a second UE to measure UE-to-UE CLI using the CLI-RS and the time behavior. The second UE may then report the measured CLI indicating a level of interference caused by the first UE.

  • Publication number: 20220116821
    Abstract: Some embodiments of this disclosure include apparatuses and methods for supporting integrated access and backhaul (IAB) networks. IAB nodes may be configured to broadcast in-raster and off-raster synchronization signal blocks (SSBs) for establishing communications with mobile devices and/or user equipment (UE). The SSBs may provide control resource set (CORESET) data used for establishing a communication channel between a UE and an IAB node. The CORESET data may be configured to support the broadcast of off-raster SSBs in wireless communication systems. In some embodiments, the in-raster SSB and the off-raster SSB may share the same CORESET. In this case, the IAB may modify a bit pattern of configuration table corresponding to the shared CORESET and broadcast the in-raster SSB and the off-raster SSB while including the modified bit pattern.
