  • Publication number: 20230029514
    Abstract: Methods and apparatuses are disclosed for configuring full power transmission modes in a UE. The disclosed full power transmission modes include a Mode 0 and a Mode 3, which are enhancements over previous modes disclosed in the 3GPP specification. The UE gathers supported modes and configuration capabilities, such as number of ports and supported coherency schemes, and forwards the configuration capabilities to the network. The network analyzes the received information and selects a supported full power transmission mode based on the UE capabilities. The selection is then transmitted to the UE in a PUSCH-Config message. The UE extracts the selection from the PUSCH-Config message, and configures its radio accordingly.

  • Patent number: 11570782
    Abstract: A user equipment (UE) transmits concurrent channel state information (CSI) processing capability information to a base station. The capability information can take various forms, and is intended to constrain the base station in the types of CSI requests that can be made to the UE. For example, the UE may indicate different CSI processing capabilities for intra-CC and inter-CC cases and/or for different codebook types. The UE may also specify supported combinations of codebook types for concurrent CSI reporting. The UE may also specify maximum resources or weighting factors for different codebook types. The UE may further restrict the rank information it provides and use a priority rule for “dropping” CSI report data due to payload size restrictions. The base station may direct, or the UE may implement, improved utilization of CSI resources that are shared for multiple concurrent CSI reports. Minimum time requirements for CSI reporting may also be relaxed.

  • Publication number: 20230024437
    Abstract: A network device (e.g., a user equipment (UE), a new radio NB (gNB), or other network component) can process or generate a physical shared channel based on a number of resource blocks determined by one or more formulas for a transport block size (TBS). In response to determining a result of the one or more formulas based on one or more received parameters a configured action for the physical shared channel can be determined based on the number of resource elements (REs). A radio frequency (RF) interface, is configured to provide, to RF circuitry, data for transmitting a new radio (NR) communication based on the configured action.

    Abstract: Techniques discussed herein can facilitate successful decoding of Physical Downlink Shared Channel (PDSCH) based on a reduced number of retransmissions. Based on a given PDSCH, embodiments discussed herein can communicate feedback (e.g., Hybrid Automatic Repeat reQuest (HARQ) feedback, Channel State Information (CSI) feedback) that indicates an amount of additional information that can allow a User Equipment (UE) to successfully decode the PDSCH. In some embodiments, the feedback can indicate a requested Redundancy Version (RV) sequence that can allow the UE to successfully decode the PDSCH. In other embodiments, the feedback can indicate the amount of additional information, based on which a receiving Base Station (BS) can select a RV sequence.

  • Publication number: 20230025057
    Abstract: Some embodiments include an apparatus, method, and computer program product for using group based reporting for beam management in a 5G wireless communications system. A user equipment (UE) can determine based on a signal-to-interference-plus noise ratio (SINR) or reference signal received power (RSRP) measurement, a ranking of two or more beam combinations, and transmit the ranking to a 5G node B (gNB). The UE can receive from the gNB, a transmission configuration indicator (TCI) codepoint that identifies a combination of two or more beams, where the TCI codepoint is based at least on the ranking. The UE can receive simultaneous transmissions via the combination, and transmit a report to the gNB that identifies by the TCI codepoint, SINRs that corresponds to the combination. In some embodiments the UE can simultaneously transmit on a second combination identified by a sounding reference signal (SRS) resource indicator (SRI) codepoint.

  • Publication number: 20230014328
    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.
