  • Publication number: 20220201649
    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.

  • 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.

  • Publication number: 20220174692
    Abstract: In a general aspect, a User Equipment (UE) in a cellular communications network receives a Radio Resource Control (RRC) signaling message from a base station communicatively coupled to the UE over a communications channel. The UE accesses a search space in the RRC signaling message. The UE identifies a fallback Downlink Control Information (DCI) Information Element (IE) included in the search space. The UE determines whether an aggregation factor is indicated in the fallback DCI IE for shared channel communications with the base station, over multiple slots in the communications channel. The UE determines an uplink/downlink (UL/DL) configuration for transmission on the communications channel. The UE schedules an aggregated transmission over multiple slots in the communications channel based on the aggregation factor and the uplink/downlink configuration.

  • 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.
