Abstract: Various communication systems may benefit from the appropriate selection of aspects of operation of the communication system. For example, certain wireless communication systems, such as fifth generation (5G), long term evolution advanced (LTE-A), and wireless local area network (WLAN) communication systems, may benefit from appropriate random access preamble selection. A method can include determining that a user equipment should consider at least one beam-specific parameter. The method can also include indicating to the user equipment to consider the at least one beam-specific parameter.

Abstract: Example embodiments of the present disclosure provide a solution for handling expiry of at least one time alignment timer (TAT) of multiple timing advance groups (TAGs) associated with a serving cell. In an example method, the terminal device receives determines at least two TAGs for a serving cell, wherein the at least two TAGs comprise a primary TAG and a secondary TAG. The terminal device determines whether at least one TAT of the at least two TAGs has expired and maintain, based on determining that the at least one TAT has expired, one of the primary TAG and the secondary TAG. In this way, only a single TAG is maintained once the terminal device has single TAT/no TAT running removing ambiguities in RA procedure/UL signal transmissions. Since the network is aware of the TAT expiry, it knows behaviour of the terminal device and can act accordingly.

Abstract: Embodiments of the present disclosure relate to devices, methods, apparatuses and computer-readable storage medium for determination of concurrent beam failure. In some example embodiments, a terminal device detects a first beam failure associated with a first set of reference signals used for beam failure detection. The terminal device determines whether a second beam failure associated with a second set of reference signals used for beam failure detection is recovered in response to detecting the first beam failure.

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: 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.

Abstract: Systems, methods, apparatuses, and computer program products for configuration and transmission of a channel state information reference signal (CSI-RS). A method may include forwarding, to a network element, synchronization signal block measurements of a target cell along with synchronization signal block indices. The method may also include requesting the network element to provide a channel state information reference signal configuration for a channel state information reference signal index whose source reference signal corresponds to at least one of the synchronization signal block indices. The method may further include receiving the channel state information reference signal configuration from the network element. In addition, the method may include transmitting the channel state information reference signal configuration to a user equipment. Further, the method may include receiving a measurement report on the channel state information reference signal index according to the channel state information reference signal configuration.
