Example embodiments of the present disclosure relate to a solution for determining a set of physical random access channel (PRACH) occasions. In the solution, a first apparatus receives, from a second apparatus, configuration information indicating a plurality of PRACH occasions comprising PRACH occasions in uplink resource and PRACH occasions in sub-band non-overlapping full-duplex (SBFD) resource; determines, based on the configuration information, and for each frequency resource index for frequency multiplexed PRACH occasions, a starting PRACH occasion of a set of PRACH occasions for a PRACH transmission with preamble repetitions from the PRACH occasions in uplink resource and the PRACH occasions in SBFD resource, and performs, to the second apparatus, the PRACH transmission based at least in part on the starting PRACH occasion of the set.

Determination for uplink repetitions

Techniques of performing CSI reporting include identifying a cluster of TRPs sharing common information in their CSI and transmitting a complete CSI report to a selected TRP of the cluster while transmitting partial CSIs reports to other TRPs of the cluster. Along these lines, in an example implementation, a UE receives a CSI-RS from a network, with the CSI-RS carrying a plurality of reference symbols from a plurality of TRPs. Based on the plurality of symbols, the UE generates TRP data representing CSI feedback for each of the TRPs. From the CSI feedback, the UE identifies, as a cluster, a subset of the TRPs that share common information within the CSI feedback. The UE then sends first identification data identifying the subset of the TRPs that make up the cluster to the network.

Embodiments of the present disclosure disclose devices, methods and apparatuses for spatial adaption. A terminal device obtains a spatial pattern configuration of reference signal transmission from a network device. The spatial pattern configuration is indicative of whether a plurality of spatial patterns have different energy levels. The terminal device then transmits a measurement report to a network device. The measurement report comprises one or more spatial patterns measured by the terminal device based on the spatial pattern configuration.

The method may further include transmitting, by the user equipment, the at least one indication of the at least one first network entity that satisfies the at least one beam-failure condition to at least one second network entity.
