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: Systems, methods, apparatuses, and computer program products for enabling dynamic switching between multi-transmission reception point (multi-TRP) and single-transmission reception point (single-TRP). A method may include receiving a first indication in a downlink control information or a medium access control control element. The method may further include determining, at a user equipment, whether to apply a multi-transmission reception point physical uplink shared channel scheme or a single-transmission reception point physical uplink shared channel scheme for transmitting a transport block based on the first indication. In addition, the method may include interpreting at least one downlink control information field differently depending on whether it is determined that the single-transmission reception point physical uplink shared channel scheme or the multi-transmission reception point physical uplink shared channel scheme is applicable.

Abstract: Techniques of generating CSI reports include designating at least one of the reports as a reference and the other reports as dependent on the reference. For example, a dependent CSI report may have a differential value of a CSI quantity rather than a raw value of the CSI quantity. Because generally for parameters in a CSI report, the differential quantity has a smaller range of values than the raw values of the CSI quantity, a quantization of the differential value of the CSI quantity will have fewer bits than the raw value; for example, for L1-RSRP, the raw value has 7 bits while the differential value has 4 bits. In another example, a dependent value of a CSI quantity is a flag indicating that the CSI quantity value is located in a reference CSI report.

Abstract: Systems, methods, apparatuses, and computer program products for channel state information (CSI) configuration and reporting for multi-transmission reception point (TRP) operation are provided. One method may include configuring a user equipment (UE), by a network node, to provide independent channel state information (CSI) feedback per transmission reception point (TRP) and to indicate additional information. The configuring of the UE may include configuring the UE with at least one of several reporting options for generating a combined channel state information (CSI) report.

Abstract: The present disclosure relates generally to the field of wireless communications, and particularly to a technique for performing the beam failure recovery (BFR) of transmission reception points (TRPs) in a multiple-TRP (mTRP) scenario. More specifically, the technique involves defining rules according to which a UE may determine that the TRPs have failed concurrently or the TRPs are considered to fail individually in the mTRP scenario. Such rules are defined based on current counter values of beam failure instance (BFI) counters used by the UE for each of the TRPs. In some embodiments, the rules may be additionally defined based on current timer statuses of timers supervising the BFI counters. By using the rules thus defined, it is possible for the UE to clearly determine when it is required to use the BFR mechanism individually for at least one of the TRPs or concurrently for all the TRPs in one or more cells.
