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.

Abstract: Various example embodiments relate to methods, devices and systems that support early beam failure recovery. A terminal device may terminal device may comprise at least one processor and at least one memory including computer program code. The at least one memory and the computer program code may be configured to, with the at least one processor, cause the terminal device to perform actions including detecting a beam failure state in association with at least one serving beam, and determining if at least one non-serving beam better than the at least one serving beam is available. The actions may further include triggering an early beam failure recovery (BFR) procedure in a case where the beam failure state is detected and the at least one non-serving beam better than the at least one serving beam is available.

Abstract: According to embodiments of the present disclosure, a first device receives a configuration of a paging indication from a second device. The configuration indicates how to monitor the paging indication and mapping between the paging indication and a set of paging occasions. The first device monitors a paging message in a paging occasion associated with the first device. In this way, it can reduce latency and save power at the first device. Further, it also saves signaling for paging.

Abstract: Devices, methods and computer programs for compensation of residual time-frequency error(s) in communications between a network node device and a client device are disclosed. A network node device determines an auxiliary reference signal indication comprising presence information and location information of an auxiliary reference signal in a physical downlink channel transmission. The network node device transmits to the client device the auxiliary reference signal associated with a physical downlink channel in accordance with the determined auxiliary reference signal indication. The client device uses the received auxiliary reference signal for the compensation of the residual time-frequency error(s) in the communications.
