  • Patent number: 11356828
    Abstract: Embodiments of a User Equipment (UE), generation Node-B (gNB) and methods of communication are generally described herein. The UE may receive a narrowband physical downlink control channel (NPDCCH) that includes an uplink scheduling parameter. The UE may determine an uplink scheduling delay for transmission of a narrowband physical uplink shared channel (NPUSCH) in accordance with time-division duplexing (TDD). The uplink scheduling delay may be based on a sum of a predetermined first number of subframes and a variable second number of subframes. The second number of subframes may be based on a window of variable size that starts when the first number of subframes has elapsed since reception of the NPDCCH, and ends when a number of uplink subframes has elapsed since the start of the window. The number of uplink subframes may be indicated by the uplink scheduling parameter.

  • Patent number: 11343052
    Abstract: A network device such as an evolved NodeB (eNB) or next generation NodeB (gNB) can configure a set of user equipment (UE) for cell reference signal (CRS) muting in order to provide better channel quality and power efficiency in communications. Where an eNB mutes CRS transmissions that are not needed by any UE, an improvement in downlink throughput and reduce connection drop rate can be generated. A CRS muting capability can be determined based on a user equipment (UE) capability information. According to the CRS muting capability of a UE, CRS muting can be generated in a physical channel outside of a narrow band (NB) or a wide band (WB) plus/minus X physical resource blocks (PRBs), wherein X is a non-negative integer, based on the CRS muting capability.

  • Publication number: 20220124622
    Abstract: Embodiments are provided for resource monitoring and power saving in a user equipment (UE) operating according to a discontinuous reception (DRX) in new radio (NR) wireless communication system. The UE, operating in the DRX mode, monitors for a wake up occasion in control signal prior to the DRX ON time. If the wake occasion is detected, then the EFE monitors for a channel state information (CSI) resource signal (RS) prior to the DRX ON time. If no wake up occasion is detected, then at least a portion of the UE remains in a sleep mode prior to DRX ON time.

  • Patent number: 11284372
    Abstract: Systems and methods of reducing power consumption associated with paging or cDRX mode are described. A wake-up receiver (WUR) wakes up from an idle mode or cDRX state. Whether a wake-up signal (WUS) has been received by the WUR is determined. The WUS is a low-complexity signal that is less complicated than a PDCCH or PDSCH and is repeated multiple times at resource elements as indicated in a configuration from an eNB. If received, a baseband transceiver wakes up for reception of a PDCCH for the UE in a PO when the UE is in the idle mode or a PDSCH for the UE when the UE is in the cDRX state.

  • Publication number: 20220070840
    Abstract: Systems and methods of early termination of uplink data transmissions for a UE are described. The UE transmits capacity information that indicates that the UE supports use of an ETS. The ETS indicates successful reception by the eNB of the uplink data prior to an end of a scheduled transmission period to transmit repeated instances of the data. The UE receives a schedule for repeated transmissions of the data that is based on a coverage level of the UE, and then transmits sets of one or more repetitions. After the transmission, the UE monitors a predetermined resource whether the ETS is present or whether the ETS indicates an ACK. If the ETS indicates successful reception, the UE terminates transmission of the remaining repetitions of the data and enters a sleep mode or transmits other uplink data.
