  • Publication number: 20250227694
    Abstract: An apparatus and system of supporting simultaneous transmission over multi-panel (STxMP) uplink (UL) transmissions are described. At least one downlink control information (DCI) is used to schedule STxMP UL transmission to multiple transmit-receive points (TRPs). The DCI indicates whether time domain (TD) repetition is to be applied, in addition to time domain and/or frequency domain resource location for different multiplexing schemes. Aperiodic-channel state information (A-CSI) or semi-persistent CSI (SP-CSI) multiplexing is multiplexed within one or more of the repetitions. One or more sounding reference signal (SRS) resource indication (SRI) fields in the DCI indicate the SRS resources to use for the transmission. Mechanisms of physical uplink control channel (PUCCH) resource configuration are described for STxMP operation.

A demodulation reference signal (DMRS) is encoded for transmission to the base station within a plurality of DMRS symbols based on the PUSCH allocation. A phase tracking reference signal (PT-RS) time domain density is determined based on the MCS index and a number count of the DM-RS symbols for the DM-RS transmission. The PTRS is encoded for transmission using a plurality of PT-RS symbols based on the determined time domain density. The plurality of symbols includes one or both of front-loaded DM-RS symbols and additional DM-RS symbols.

  • Patent number: 12328600
    Abstract: Techniques are provided for selecting a spatial relation for a physical uplink shared channel (PUSCH) transmission by a user equipment (UE) operating in a multi-transmission reception point (TRP) multi-antenna panel environment. For example, the UE prepares a PUSCH transmission intended for a first TRP of a plurality of TRPs available to the UE in the wireless network, and determines a first antenna port group of a plurality of antenna port groups of the UE that is more directionally aligned with the first TRP than other antenna port groups of the plurality of antenna port groups. The UE further transmits the PUSCH transmission to the first TRP via the first antenna port group using a default spatial relation used for a physical uplink control channel (PUCCH) communication with the first TRP via the first antenna port group.

  • 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.

  • 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: 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.

  • 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.

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.
