Abstract: 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.

Abstract: Method, apparatus, and computer program product for a CORESET beam recovery procedure and a QCL association beam recovery procedure where a condition or rule based UE initiated change of active TCI state is used. The CORESET beam recovery procedure involves a downlink reference signal corresponding to a transmission configuration indication state activated for certain CORESET being determined as a beam failure detection resource. The QCL association beam recovery procedure concerns a UE transmitting a UL request signal to require switching an active TCI state of the CORESET to a currently deactivated TCI state of the same CORESET.

Abstract: Methods and apparatus, including computer program products, are provided for control channel monitoring. In some example embodiments, there may be provided a method that includes receiving, at the user equipment, an indication of a codepoint activation, wherein the codepoint activation indicates that a transmission configuration indicator state being activated is associated with a second physical cell identifier different from a first physical cell identifier of a serving cell of the user equipment; and in response to the transmission configuration indicator state being activated in association with the second physical cell identifier, suspending control channel monitoring of at least one set of core resources associated with the first physical cell identifier of the serving cell of the user equipment. Related systems, methods, and articles of manufacture are also disclosed.

Abstract: A UE determines a PMI, by performing at least the following: determining an intermediate set of vectors from a FD codebook; forming a subset of the intermediate set of vectors; mapping the subset of vectors to a combinatorial indicator; and forming the PMI at least from the combinatorial indicator. The UE sends the PMI toward a wireless network. A base station receives the PMI from the UE. The PMI includes a combinatorial indicator that maps to a subset of vectors from the FD codebook. The base station determines, using at least the received PMI, information from at least the FD codebook to apply to data for transmission toward the UE.

Abstract: The specification and drawings present methods and apparatuses for feedback signaling for beamforming purposes in a multiple input-multiple output (MIMO) radio environment. According to an embodiment of the invention, a mobile device is configured to measure an integer number P of different beam groups, each group representing one or more transmit beams and each group corresponding to one or more antenna ports at the mobile device. The mobile device is triggered according to the configuration to provide feedback. The radio access node transmits reference signals on each of the transmit beams across all of the groups for measurement by the mobile device and receives the triggered feedback including, for each of the different beam groups, at least one best match between a transmit beam of the respective group and a corresponding antenna port and an indication of measurement results for the best match.
