Abstract: Method and UE are provided for performing UL transmissions to multiple TRPs. In particular, a UE can determine whether two UL transmissions are associated with one TRP before being transmitted, and the two UL transmissions are overlapped in at least one symbol in time domain.

Abstract: Method and user equipment (UE) are provided for the TCI state indication for PUSCH transmission. In one novel aspect, the UE maps PUSCH transmission with codebook/noncodebook-based TCI states based on codepoint for SRS resource set of DCI format 0_1 or DCI format 0_2. In one embodiment, UE applies the first or the second TCI state to all PUSCH transmission occasions when the codepoint is “00” or “01”, respectively. When the codepoint is “10” or “11”, the UE applies the first and the second indicated joint/UL TCI state to the PUSCH transmission occasions (s) associated with the first and second SRS resource set, respectively when no multi-panel scheme is configured; and when multi-panel scheme is configured with, such as “SDMscheme”, UE applies the first and the second indicated joint/UL TCI state to the PUSCH antenna ports associated with the first and second SRS resource set, respectively.

Abstract: A method of L1/L2-based mobility with signaling optimization using base (reference) configuration and replaceable (delta) configuration for candidate cells is proposed. All candidates can be configured at different levels provided by Radio Resource Control (RRC) signaling. To support L1/L2-triggered mobility (LTM), there is a common base configuration for candidates, and the candidates are modelled as replaceable configurations which are delta configurations on top of the common base configuration (instead of UE's current RRC configuration). The common and replaceable configurations are also referred to as reference configuration and candidate delta configuration. The candidate delta configuration is applied on top of the reference configuration to form a complete candidate configuration for handover.
