    摘要: 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.

    摘要: 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.

    摘要: 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.

    摘要: Examples of the present disclosure relate to User Equipment positioning. Certain examples provide an apparatus (10), for example such as a RAN node (120) or a Location server (140), configured to: determine Position Reference Signal, PRS, configuration information (605, 705) comprising information for enabling a network element, for example such as a UE (110) or a RAN node (120), of a RAN (100) to: send a PRS (200), wherein the PRS comprises: a first portion (201) of the PRS configured to be sent in a first time interval (T1) over a first frequency range (fr1); a second portion (202) of the PRS configured to be sent in a second time interval (T2), different to the first time interval, over a second frequency range (fr2), wherein the second frequency range partially overlaps the first frequency range thereby defining an overlapping frequency range (ofr); and wherein a subrange of frequencies (ufr) of the second frequency range is not used to send the second portion of the PRS; and send, the PRS configuration information to the network element of the RAN.

    摘要: One embodiment is directed to a method comprising estimating a velocity vector that is experienced by an apparatus; reporting to a network element, NE, the velocity vector; receiving from the NE at least one primary reference signal, RS, which will be experienced during a predicted trajectory, and at least one secondary RS that will potentially be experienced during the predicted trajectory; sending to the NE feedback based on the at least one primary RS and the at least one secondary RS; and sending an update of the velocity vector to the NE.
