Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from a base station, a random access channel (RACH) occasion (RO) configuration that includes information related to ordered preamble resources. The UE may generate a preamble resource index according to various parameters selected based on the RO configuration information that relates to the ordered preamble resources. The UE may generate an uplink RACH message that includes a preamble based at least in part on the preamble resource index and a payload associated with a physical uplink shared channel (PUSCH) resource unit (PRU) mapped to the preamble resource index. After decoding the uplink RACH message, the base station may send a response message including scrambled downlink control information (e.g., based on a scrambling identifier or payload information associated with the uplink RACH message). Numerous other aspects are provided.

Abstract: In aspects, a user equipment (UE) forms groups of overlapping uplink transmissions among component carriers (CCs), and moves in time all uplink transmissions within a group, except an earliest transmission, to align leading edges. The UE then determines, for each uplink transmission, if a joint timeline is satisfied, and allocates total transmission power depending on whether the timeline is satisfied for all uplink transmissions. In aspects, a base station transmits, to a UE, a transmit power configuration that identifies a reserved power for uplink transmissions of cell groups. The base station then transmits, to the UE, an uplink grant or configuration that identifies a transmission power for a cell group in excess of its reserved power, and receives, from the UE, uplink transmissions that exhibit an allocation of total transmission power according to the reserved power and the transmission power for the cell group in excess of the reserved power.

Residual TA is estimated using the reported information related to the TA applied and the detected PRACH.
