  • Publication number: 20240235748
    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.

  • Patent number: 12025721
    Abstract: Systems and methods of a wireless communications system using signals not traditionally used for positioning purposes for positioning measurements in both uplink (UL) and downlink (DL) are described herein. A user equipment (UE) may generate a UE capability information message indicating one or more signal types that the LE can process for DL positioning measurements and/or that the UE can send for UL positioning measurements. The one or more signal types so indicated may include signals not traditionally used for positioning measurements. The UE may send, to the base station, the UE capability information message. The wireless communications system may then configure the base station and/or the UE to use such signal types with one or more positioning methods. In some embodiments, the base station may also indicate to the UE a subset of signals of an indicated type which should be processed for DL measurements/sent for UL measurements.

  • Patent number: 12028876
    Abstract: Systems and methods disclosed herein relate to acknowledgement signaling sent by a user equipment (UE) in response to downlink control information (DCI) received from a base station that schedules the use of multiple physical uplink control channels (multi-PUSCH) or multiple physical downlink control channels (multi-PDSCH). Acknowledgement signaling may inform the base station that DCI scheduling the multi-PUSCH/multi-PDSCH was received (or not), so that the base station may reclaim those scheduled resources in the case that the UE remains unaware of them. Methods for performing this signaling include, e.g., the use of HARQ-ACK codebooks (whether in a semi-static or dynamic manner), and aperiodic sounding reference signals (A-SRS). Embodiments involving such DCI received across multiple component carriers of different serving cells of the UE are contemplated.

  • Patent number: 12022469
    Abstract: A user equipment (UE) may increase the reliability of transmission of a Physical Uplink Control Channel (PUCCH) by transmitting repeated copies of the PUCCH, according to a repetition pattern spanning one or more slots. In an intra-slot mode, more than one copy may be transmitted within each configured slot, with or without frequency hopping. The number of copies as well as a temporal gap between the transmission of successive copies may be configured by the network. The repetition pattern may or may not be interrupted by slot boundaries. In an inter-slot mode, one copy is transmitted per configured slot. Different copies may be transmitted in different directions, according to a spatial consistency pattern. The UE may perform repeated transmission of PUCCHs to different Transmission-Reception Points (TRPs) using respectively different timing advances and/or transmit power levels.

  • Publication number: 20240205834
    Abstract: Embodiments of the present disclosure relate to Physical Uplink Control Channel (PUCCH) reliability enhancement. According to embodiments of the present disclosure, a processor of a UE receives, from a BS associated with a first TRP and a second TRP, a first message for configuring a PUCCH resource to be used by the UE to perform a PUCCH transmission with the BS. In this case, the first message indicates a first configuration corresponding to the first TRP and the first configuration comprises at least one power control parameter associated with the first TRP. The message further indicates a second configuration corresponding to the second TRP and the second configuration comprises at least one power control parameter associated with the second TRP. The processor performs the PUCCH transmission with the BS via the first and second TRPs based on the first message. In this way, the reliability and robustness of the PUCCH transmission for multiple TRP is enhanced.
