Abstract: Systems, methods, apparatuses, and computer program products for determining transmission configuration indicator (TCI) state are provided. One method may include detecting, by a user equipment, one or more downlink control information (DCIs), and determining, by the user equipment, at least one of the one or more DCIs. Acknowledgement information for the determined at least one of the one or more DCIs is transmitted in a same symbol, in a same slot or in a same uplink channel. The method may also include determining, by the user equipment, a first TCI state indicated in a first DCI, where the first DCI is latest in time among the determined at least one of the one or more DCIs, and applying, by the user equipment, the first TCI state.

Abstract: Systems, methods, apparatuses, and computer program products for fast downlink beam switching assumptions related to quasi-colocation are provided. For example, a method can include determining whether a reported downlink reference signal corresponds to a reference signal, based on a spatial reception parameter corresponding to channel conditions and supporting beamforming, with a resource set that is configured to a user equipment with a tracking reference signal parameter. The method can also include interpreting a downlink reception parameter based on the determination regarding the reported downlink reference signal. The method can further include controlling at least a receive beam or a transmit beam of the user equipment based on the interpretation of the downlink transmission configuration indicator state.

Abstract: Systems, methods, apparatuses, and computer program products for facilitating triggered PDCCH-ordered PRACH transmissions in multi-TRP scenarios. One method may include a UE determining that a first TCI state is to be applied in a first slot and a second TCI state is to be applied in a second slot. The first TCI state is associated with a first TAG ID, a second TCI state is associated with a second TAG ID different than the first TAG ID, and the second slot is succeeding and adjacent to the first slot. The method may further include, based upon the determining, transmitting or dropping at least one of at least one uplink transmission in the first slot or at least one uplink transmission in a second slot.

Abstract: A method performed by a user device, including performing the steps of: receiving, from a network entity, one or both of: at least one resource of at least one downlink reference signal, and an indication; triggering switching, from a first association to a second association between at least two CORESETPoolIndex values and at least two sounding reference signal resource sets, based on a determination of one or both of: a measured value of the at least one DL reference signal and the indication; and transmitting respectively, to the network entity, corresponding resources of one or more sounding reference signals that correspond to the second association after the switching.

Abstract: Example embodiments of the present disclosure relate to an apparatus receiving an instruction to perform interchanging of an association of coreset pool indices with sounding reference signal (SRS) resource sets. The apparatus interchanges an association of a first coreset pool index with a first SRS resource set of the SRS resource sets and an association of a second coreset pool index with a second SRS resource set of the SRS resource sets to an association of the first coreset pool index with the second SRS resource set and an association of the second coreset pool index with the first SRS resource set. The apparatus transmits one or more SRS transmissions associated with the first or second coreset pool index and/or a physical uplink shared channel (PUSCH) transmission based on an SRS resource indicator (SRI) associated with the first or second coreset pool index, in accordance with the interchanged association.

Abstract: Embodiments of the present disclosure relate to methods and apparatus for beam maintenance in a radio access network, in particular, through random access preamble transmission for beam maintenance. A terminal device receives, from a network device, a resource configuration for contention-free random access. The resource configuration indicates a plurality of CFRA resources each associated with a respective synchronization signal and physical broadcast channel block index or channel state information reference signal index. The plurality of CFRA resources are applicable for timing advance acquiring in a target network device. The terminal device transmits, to the target network device, one or more CFRA physical random access channels based on the resource configuration. In this way, beam maintenance may be performed based on an SSB index or CSI-RS index associated with one of the transmitted CFRA PRACH(s) before a cell switch command or a random access response.
