  • Publication number: 20220394671
    Abstract: When a UE is in a power saving state, and the network has downlink data to send to the UE, a paging message may be transmitted in the downlink. Paging may have high overhead when beamforming is implemented. In some embodiments, a UE-specific notification is instead transmitted in a downlink beam pointed in the direction of the UE. The UE-specific notification may be a paging message specific to the UE that indicates that there is downlink data for transmission to that UE. However, more generally the UE-specific notification may be any type of downlink notification for a UE. The notification may include downlink beam information.

  • Publication number: 20220377741
    Abstract: By defining more SCS options and Discrete Fourier Transform (“DFT”) options for transmissions in future networks, there arises cause to select from among the options, with aspects of the channel as guidance for the selection. In addition, new CP designs may be defined for use with the new SCS options and the new DFT options along with methods of selecting a CP design appropriate to a particular situation. The new CP designs may be shown to have smaller CP overhead when compared to the known CP designs used for known combinations of an SCS option with an FFT size option. New sampling frequency design options and new system basic timing options may also be defined, along with methods of making appropriate selections from among these options. Control signaling using higher layers may be used to distribute configuration options that include multiple SCS options, CP duration options, sampling frequency options and DFT size options per sub-band.

  • Patent number: 11503575
    Abstract: The present disclosure relates to a terminal device, in which a processing module selects one or more normal carriers or special carriers from a first carrier set for an uplink subframe, where the first carrier set includes all carriers in carrier aggregation that are used by the terminal device to send a first uplink subframe; and a sending module cancels sending of the uplink subframe on one or more carriers, where the special carrier is a carrier on which the terminal device sends neither uplink data nor uplink control information in uplink, and the normal carrier is a carrier that is used by the terminal device to send uplink data and/or uplink control information. An uplink subframe on some carriers is rejected, thereby resolving a problem that information such as a downlink channel characteristic of a carrier cannot be obtained when no uplink reference signal is sent on the carrier.
