    Abstract: PUCCH carrier switching includes decoding an RRC configuration that indicates a reference cell having a reference cell slot numerology. A reference cell slot is determined for PUCCH transmissions based on the reference cell slot numerology. The determined slot is used for transmission of an SR, CSI, or HARQ-ACK, A DCI indicating a candidate target PUCCH cell having a candidate target PUCCH cell slot numerology and a slot of the candidate target PUCCH cell is decoded. A target PUCCH cell having a target PUCCH cell slot numerology is determined for transmitting the SR, the CSI, or the HARQ-ACK. The determined slot is mapped to a corresponding slot of the target PUCCH cell. A PUCCH resource is determined for transmitting the SR, the CSI, or the HARQ-ACK using the corresponding slot of the target PUCCH cell. The PUCCH resource determination is based on a PUCCH configuration of the target PUCCH cell.

  • Patent number: 12035361
    Abstract: A user equipment is configured to connect to a base station (BS) over a shared channel subject to channel access operations. The UE receives a first configuration for a BS-initiated fixed frame period (FFP) (BS-FFP) and a second configuration for a UE-initiated FFP (UE-FFP), determines that no downlink (DL) transmissions are detected during a predefined time of the BS-FFP and determines that at least one condition associated with an uplink (UL) transmission is satisfied. When no downlink (DL) transmissions are detected during the predefined time of the BS-FFP and the at least one condition is satisfied, the UE performs a UE-initiated channel access operation. When the UE-initiated channel access operation is successful, the UE performs the UL transmission during the UE-FFP.

  • 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.

  • Patent number: 12035251
    Abstract: Various techniques are presented to improve phase tracking reference signal (PTRS) performance with respect to very high frequency communications. According to some embodiments, increased power boosting may be applied to improve PTRS performance, while still keeping power spectral density (PSD) within ETSI Broadband Radio Access Networks (BRAN) limits. In some cases, the power boosting may be semi-static and/or dynamic. In other embodiments, the improved performance may be achieved by dynamically changing time and/or frequency density of the PTRS. In other embodiments, a multi-port configuration may be used for the downlink PTRS. In other embodiments, one or more PTRS configurations may be determined per SCS and/or frequency band, e.g., based on traffic type, channel priority, parameters signaled in the slot format indication (SFI), etc. In other embodiments, common phase error (CPE) estimates may be obtained for those OFDM symbols without PTRS by interpolating the available PTRS estimates in the time domain.
