  • Patent number: 12267160
    Abstract: A user equipment wireless communication device in a wireless communication environment receives a signal from the network that includes a radio network temporary ID. From the radio network temporary ID, the user equipment is capable of determining whether a phase tracking reference signal is present based on the radio network temporary ID. If any of these are identified by the radio network temporary ID, then the user equipment determines that a phase tracking reference signal is present. After the user equipment has determined that the phase tracking reference signal is present, the user equipment can then determine which phase tracking reference signal antenna ports are to be used based on the values of the transmitted precoding matrix indicator value and the transmit rank indicator.

    Abstract: Systems, apparatuses, methods, and computer-readable media are directed to techniques for codebook support for different antenna structures, such as a user equipment (UE) with a non-uniform antenna array (e.g. with different distances between antenna elements) and/or multiple antenna panels. Embodiments further provide techniques for enhanced operation in full power mode 2. For example, embodiments provide techniques for antenna virtualization to form virtual antenna ports from subsets of transmit antennas of the UE (e.g., from eight transmit antennas to two, four, or six virtual antenna ports). Other embodiments may be described and claimed.

  • Patent number: 12261671
    Abstract: Apparatuses, systems, and methods for multiplexing of PUCCH for beam failure recovery and other signals. A UE may determine a transmission dropping rule and a transmission power scaling rule for a PUCCH which is dedicatedly configured for secondary BFR transmission, such as a PUCCH-BFR, when it is multiplexed with at least one other signal. The PUCCH-BFR and the at least one other signal may be multiplexed in a CC or in multiple CCs. The UE may determine a transmission dropping rule, e.g., so that UE can transmit an uplink signals with higher priority and drop the other uplink signal with lower priority to avoid beam collisions. The UE may determine a transmission power scaling rule, e.g., so the UE may scale transmission power within a CC and/or across CCs. The UE may multiplex the PUCCH-BFR with the at least one other signal according to the rules.

  • Patent number: 12238029
    Abstract: A user equipment (UE) can include processing circuitry configured to decode control information of a physical downlink control channel (PDCCH) received via a resource within a control resource set (CORESET) occupying a subset of a plurality of OFDM symbols within a slot. At least one of the symbols in the subset coincides with a pre-defined symbol location associated with a demodulation reference signal (DM-RS) of a PDSCII. The DM-RS can be detected within the slot, the DM-RS starting at a symbol location that is shifted from the pre-defined symbol location and following the subset of symbols. Downlink data scheduled by the PDCCH and received via the PDSCH can be decoded, where the decoding is based on the detected DM-RS.

  • Patent number: 12238025
    Abstract: The present disclosure provides systems and methods for mapping transmission configuration indication (TCI) states to demodulation reference signal (DMRS) ports groups in a wireless network. For instance, a TCI state to DMRS ports group mapping of a user equipment (UE) can be determined. Each DMRS port in a DMRS ports group shares a quasi-co-location (QCL) assumption. The TCI state to DMRS ports group mapping comprises multiple TCI state groups. The TCI state to DMRS ports group mapping corresponds each TCI state group to one or more DMRS ports groups. A TCI state group from the DMRS ports group mapping can be selected for the UE. Data indicative of the selected TCI state group and the corresponding one or more DMRS ports groups can be provided to the UE based at least in part on the TCI state group from the DMRS ports group mapping.

    Abstract: Systems, apparatuses, methods, and computer-readable media are provided for framework of layer 1 signal-to-interference plus noise ratio (L1-SINR) measurement and reporting based on channel measurement and interference measurement. The channel measurement is performed on a first set of reference signal (RS) resources, and the interference measurement is performed on a second set of RS resources. Each of the second set of RS resources is mapped to each of the first set of RS resources. The L1-SINR is determined from a first RS resource of the first set of RS resources and a second RS resource of the send set of RS resources, where the first RS resource is mapped to the second RS resource. A message including the L1-SINR is generated and transmitted to the access node.

  • Publication number: 20240381264
    Abstract: Some embodiments of this disclosure include apparatuses and methods for uplink panel selection with power saving. In some embodiments, user equipment (UE) may experience a positional change. In response, the UE may deactivate a first communication panel to save power and activate a second communication panel. The UE may then transmit a status message to a communication node indicating the activation and/or deactivation. The node may then register this activation and/or deactivation. In some embodiments, the node may monitor uplink slots from the first and second communication panel to identify the activation and deactivation. For example, if the node detects an absence of an uplink signal within a slot threshold, the node may identify the panel as being deactivated. The node may establishing communications with another panel based on a detected signal and/or the status message.
