Abstract: Methods, systems, and devices for wireless communications are described. Random access channel (RACH) occasions may be scheduled on each component carrier (CC) of a carrier aggregation (CA) configuration that includes both a time division duplexing (TDD) TD Raid band and at least one frequency division duplexing (FDD) band based on a synchronization signal/physical broadcast channel block (SSB) received in the TDD band. In some cases, the TDD band may be used to configure the RACH occasions in same and/or different CCs. Additionally or alternatively, the FDD band may configure the RACH occasions on its uplink CC based on SSBs received on other CCs. Additionally, the RACH occasions may be configured such that the UE avoids unavailable uplink slots when transmitting a first RACH message in a RACH occasion.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive configuration information identifying configurations associated with respective uplink carriers for a random access channel (RACH) message, wherein a configuration associated with a first uplink carrier, of the respective uplink carriers, is different than a configuration associated with a second uplink carrier of the respective uplink carriers. The UE may select a set of uplink carriers, of the respective uplink carriers, on which to transmit the RACH message based at least in part on the configuration information. The UE may transmit the RACH message on the selected set of uplink carriers in accordance with the configuration information. Numerous other aspects are provided.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive an indication that a high Doppler configuration is activated. The UE may detect, based at least in part on receiving the indication that the high Doppler configuration is activated, a phase tracking reference signal (PTRS) for a remaining minimum system information (RMSI) communication. The PTRS may be configured by the high Doppler configuration. Numerous other aspects are provided.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a base station (BS) may receive a first downlink determining, based at least in part on an uplink transmission schedule for a user equipment (UE), one or more communications that are to be transmitted as a cross link interference reference signal (CLI-RS) during a time window. The BS may transmit, to the UE, an instruction to transmit the one or more communications as the CLI-RS during the time window. Numerous other aspects are provided.

Abstract: Methods, systems, and devices for wireless communications are described. Generally, the described techniques provide for managing remote interference using a previously detected relationship between an aggressor base station and a victim base station. The described techniques provide for allocating reference signal sequences for various victim base stations to send to an aggressor base station. The victim base station may trigger the aggressor base station to perform reference signal monitoring based on the previously detected victim-aggressor relationship, and may transmit a reference signal carrying a unique identifier based on the triggering. The first base station may send a request that the second base station to transmit a reference signal for enabling the first base station to measure interference of a wireless channel, and performing interference mitigation techniques at the first base station, the second base station, or both, to mitigate the remote interference.
