Abstract: Aspects are provided allowing a UE to transmit repetitions of an ULT, PEI-R, or other uplink reference signal for on-demand SSB, RMSI, or paging transmissions. A base station initially transmits an indication of a configured uplink repetition mode, which may comprise a first, second, or third mode in which a one-to-one, one-to-many, or many-to-many mapping exists between downlink reference signals and uplink occasions, respectively. Afterwards, the UE receives downlink reference signals via different transmission beams of the base station. In response to the downlink reference signals, the UE transmits an uplink reference signal repetition in one or more uplink occasions associated with one or more of the downlink reference signals according to the configured uplink repetition mode. In response to the uplink reference signal repetition, the base station may transmit a SSB, RMSI, or paging message. Thus, a balance between network energy savings and uplink signal reliability may be achieved.

Abstract: A user equipment (UE) receives reference signal resource configuration for transmitting reference signals for positioning from, e.g., a location server. The UE transmits or attempts to transmit reference signals for positioning to one or more transmission-reception points, such as a gNB.

For example, the UE may be unable to transmit the reference signals or may transmit the reference signals with lower power or a different spatial relation than configured. The UE may provide a reference signal transmission report indicating that the reference signals were not transmitted according to the reference signal resource configuration.
