  • Publication number: 20250080187
    Abstract: Methods, systems, and devices for wireless communications are described. A base station may transmit a channel state information (CSI) reference signal (CSI-RS) to a user equipment (UE) using heterogenous antenna panels, where a first antenna panel used to transmit the CSI-RS may have a different number of antenna ports than a second antenna panel used to transmit the CSI-RS. The UE may generate a codebook to report CSI based on the heterogenous antenna panels. In some cases, the UE may report compressed CSI if the antenna panels are in close proximity together.

  • Publication number: 20250039799
    Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may be configured to transmit multiple repetitions of a random access message using multiple spatial filters. In some cases, the UE may transmit each repetition of the random access message using a same transmission power determined based on one of the spatial filters. In other cases, the UE may transmit each repetition of the random access message using a different transmission power determined in accordance with power control parameters corresponding to the respective spatial filters. The UE may utilize a spatial filter of a first-received responsive random access message to perform subsequent transmissions of a random access procedure. In the case of a failure of the random access procedure, the UE may increment (or refrain from incrementing) a power ramping counter based on spatial filters used to re-initiate the random access procedure.

  • Patent number: 12200623
    Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may be receive a grant configuration including multiple set of parameters, and the UE may select a set of parameters from the configured grant based on a channel condition. In some examples, the UE may be configured to signal to a network (e.g., a base station) the selected set of parameters and their corresponding parameter values. For example, the UE may be configured to signal the selected set of parameters over semi-static signaling (e.g., radio resource control (RRC) messaging) or dynamic signaling (e.g., medium access control-control element (MAC-CE) messaging, uplink control information (UCI) messaging, or the like). By configuring the UE with multiple set of parameters, the UE may adapt to changing channel conditions, which may provide higher reliability and lower latency for wireless communications, as well as reduce power consumption for the UE.
