PUSCH Multi-TRP Scheduling with UL TCI Indication
Summary
The USPTO published patent application US20260100789A1 disclosing systems and methods for Physical Uplink Shared Channel (PUSCH) multi-Transmission/Reception Point (TRP) scheduling with Uplink Transmission Configuration Indicator (UL TCI) indication. The application covers wireless device procedures for obtaining TCI state configurations, activating/deactivating subsets of configured TCI states, and mapping indicated TCI states to transmission occasions or repetitions. When two TCI states are indicated, the wireless device transmits two different PUSCHs each corresponding to one indicated TCI state; when one TCI state is indicated, the device transmits a single PUSCH.
What changed
The USPTO published a patent application disclosing methods for PUSCH multi-TRP scheduling with UL TCI indication in wireless communication systems. The invention covers wireless device procedures including obtaining TCI state configurations for UL PUSCH scheduling, activating/deactivating subsets of configured TCI states, and mapping indicated TCI states to transmission occasions or actual repetitions. The wireless device applies transmitted precoding matrix indicator values to transmission occasions or repetitions associated with each indicated TCI state.
For telecommunications equipment manufacturers and wireless device developers, this patent application represents potential prior art in the multi-TRP scheduling space. Companies developing 5G NR compliant devices implementing multi-transmission/reception point configurations should monitor this application's prosecution for potential licensing implications or to assess freedom to operate.

Abstract
Systems and methods to support Physical Uplink Shared Channel (PUSCH) multi-Transmission/Reception Point (TRP) scheduling are provided. In some embodiments, the wireless device performs one or more of: obtaining a configuration for Transmission Configuration Indicator (TCI) states for Uplink (UL) PUSCH scheduling; activating/deactivating a subset of configured TCI states). If two TCI states are indicated, the wireless device transmits two different PUSCHs each corresponding to one of the indicated TCI states. If one TCI state is indicated, the wireless device transmits a single PUSCH corresponding to the indicated TCI state. The wireless device maps indicated TCI states to the transmission occasions or actual repetitions is preconfigured via higher layer parameter(s) or is given by a predefined rule. The wireless device applies a Transmitted Precoding Matrix Indicator (TPMI) to transmission occasions or actual repetitions associated with each indicated TCI state based on a signaled value and/or a predefined value.
