  • Patent number: 11503660
    Abstract: In a dual network link scenario, a wireless network may provide a user equipment (UE) with a measurement configuration indicating multiple inter-frequency measurement objects during an off duration of a discontinuous reception (DRX) cycle configured on a first network link. The UE may assign the inter-frequency measurement objects to a second network link if the second network link has an always-on configuration. Alternatively, if the second network link has a DRX configuration, the UE may perform some inter-frequency measurement activities on the first network link and assign some inter-frequency measurement objects to unoccupied gap occasions in the off duration for the DRX cycle configured on the second network link. In this way, the UE may save power by spending more time in a low power state, and mobility performance for the UE may be improved by increasing the efficiency and reliability of inter-frequency measurement activities.

  • Publication number: 20220360388
    Abstract: Methods, systems, and devices for wireless communication are described. A user equipment (UE) may be configured to transmit sounding reference signals (SRSs) on a first carrier over multiple symbols within a slot, the first carrier being different from a second carrier on which the UE communicates with a base station during the slot. For example, the base station may transmit, to the UE, an SRS configuration for the UE to transmit the SRSs. In accordance with the control message, the UE may tune to the first carrier and may transmit the SRSs over the multiple symbols within the slot on the first carrier before tuning back to the second carrier. In some examples, the UE may transmit a capability message to the base station indicating that the UE supports transmitting SRSs over multiple symbols within a slot before tuning back to a different carrier.

  • Publication number: 20220272568
    Abstract: Methods, systems, and devices for wireless communications are described. Techniques are described to enable wake-up signal (WUS) error handling at a user equipment (UE). The UE may detect an error pattern when attempting to receive a WUS from a base station based on a configuration for receiving the WUS. For example, the base station may transmit the configuration for receiving the WUS to a set of UEs including the UE. Based on detecting the error pattern, the UE may perform a mitigation operation based on determining the error pattern, such as waking up multiple cells to receive a transmission indicated by the WUS, transmitting a radio link failure indication to the base station, etc. Additionally or alternatively, the base station may transmit multiple WUSs to the UEs, such as a first WUS according to the configuration and a second WUS according to a reconfiguration.
