  • Patent number: 12035364
    Abstract: An apparatus may receive a media access control (MAC) control element (CE) from a base station (BS) indicating a secondary cell (SCell) to be activated in an unlicensed band. The apparatus may initiate a timer with an end value in response to receiving the MAC CE and may further adjust a radio-frequency (RF) chain from a first state to a second state corresponding to the SCell to be activated. The apparatus may determine, based on measurements of one or more synchronization signal blocks (SSBs) transmitted from the BS indicating one or more listen before talk (LBT) failures corresponding to the SCell, one or more failed SSB transmissions corresponding to the SCell. Accordingly, the apparatus may readjust, in response to expiry of the timer, the RF chain from the second state to the first state and receive one or more additional SSBs in the first state.

  • Publication number: 20240223343
    Abstract: Methods and systems are disclosed for a UE to manage and measure intra-cell cross link interference (CLI) when served by a base station operating in full-duplex FDD. The signaling may indicate to a victim UE resources to measure to determine the level of CLI from aggressor UEs. The resources used for the CLI measurement may be resources not scheduled by the base station for use by the victim UE for downlink reception, but are scheduled for use by the aggressor UEs for transmitting uplink traffic or for transmitting reference signals used to characterize the uplink channel. The victim UE may report the CLI measurements to the base station for the base station to adjust scheduling of downlink resources to the victim UE. In one aspect, the signaling from the base station may indicate to the victim UE the locations of scheduled downlink symbols that may potentially be impacted by CLI.
