  • Publication number: 20200100099
    Abstract: A method for UE capability reduction on a per-component-carrier or a per-frequency-range basis is proposed. In NR networks, UE may be operating in multiple frequency ranges (FRs) and configured with multiple component carriers (CCs) under carrier aggregation. UE can detect an overheating problem due to the RF activity supporting high bandwidth or high MIMO rank on a specific FR or a specific CC. Accordingly, UE indicates to the network a preference for a capability reduction on the specific FR or the specific CC, e.g., a reduced number of carriers, a reduced maximum bandwidth, or a reduced MIMO rank. Such per-FR or per-CC request allows UE to restrict or reduce its capability in a manner that is specific to certain component carriers and/or certain frequency ranges rather than to a global capability reduction that affects all carriers/frequencies.

  • Patent number: 10602447
    Abstract: An enhanced paging mechanism is provided for UEs waking up from a very long paging cycle to improve paging robustness and flexibility. Enhanced paging includes absolute time paging (ATP) and paging with extended wakeup time. For absolute time paging, a UE receives ATP configuration and uses the actual wall time to calculate paging occasion if a condition is satisfied. In one embodiment, the wall time is acquired from at least one of an internal UE clock, a GPS time, information broadcasted from the network, or information from a higher layer signaling. For paging with extended wakeup time, a UE applies a long paging cycle followed by multiple normal paging cycles after waking up from the long paging cycle. In one embodiment, the long paging cycle is infinite and the UE enters normal paging cycle only upon TAU-triggered paging or uplink traffic.

  • Patent number: 10594468
    Abstract: Apparatus and methods are provided for efficient bandwidth adaptation for wideband carrier. In one novel aspect, the UE starts a BWP timer upon detecting one or more BWP timer starting triggering events, resets the BWP timer upon detecting BWP resetting triggering events, and switches to the default BWP upon expiration of the BWP timer. The BWP timer starting triggering events comprises decoding a command to switch away from the default BWP, the detection of end of DL data transmission in DRX mode. In another novel aspect, the UE only decodes the DCI indication for active BWP switching in the first three OFDM symbols of a subframe or a slot. In yet another novel aspect, when the SPS is configured for the serving cell for a UE with multiple BWPs, the SPS is configured for all the BWPs accordingly.

  • Patent number: 10511989
    Abstract: A method of uplink shaping and extending UE in RRC Idle Mode is proposed. The UE processes a data packet to be sent to the network. The data packet is associated with a traffic type. If the data packet belongs to a normal traffic type, then the UE enters RRC Connected mode and thereby transmitting the data packet to the network. If the data packet belongs to a background traffic type, then the UE buffers the data packet and the UE is prohibited from entering RRC Connected mode until a triggering condition is satisfied for uplink transmission. The proposed mechanism achieves power saving by reducing the activity of uplink transmission. In addition, the proposed mechanism also reduces signaling overhead to enhance network efficiency.
