Definitions

  • the present disclosure relates to at least methods for providing reporting for beams targeting multi-panel downlink, DL, reception or uplink, UL, transmission, and receiving reporting for beams targeting multi-panel downlink, DL, reception or uplink, UL, transmission, a user equipment and a radio network node.
  • a distributed Multiple Input Multiple Output (MIMO) system is a system with multiple geographically distributed antenna panels, possibly with respective radio and processing units, where such panels jointly coordinate aspects of their transmissions (and receptions) in order to serve one or more User Equipment devices (UEs).
  • D-MIMO Distributed MIMO
  • gNBs coordinating macro gNodeBs
  • 3GPP Third Generation Partnership Program
  • Another type of D-MIMO deployments is dense localized deployments where several small-sized low-powered panels/nodes are densely deployed in a specific part of the cell requiring a capacity/reliability enhancement (e.g., in crowded parts of the macro cell area such as public squares or stadiums).
  • 6G D-MIMO deployment is dense localized deployments where several small-sized low-powered panels/nodes are densely deployed in a specific part of the cell requiring a capacity/reliability enhancement (e.g., in crowded parts of the macro cell area such as public squares or stadiums).
  • TRPs transmission and reception points
  • APs access points
  • Non-coherent joint transmissions e.g., where the same or different layers can be transmitted from different TRPs without per-TRP precoding accounting for the instantaneous (amplitude and) phase of the downlink (DL) channel, and
  • CJT Coherent joint transmissions
  • NC-JT schemes are the major type of transmission schemes considered for high-bands, since inter- TRP phase calibration needed for CJTs is more challenging to perform at high-bands: both in terms of tighter link budget, but also because the phase noise at high frequencies may make CJT infeasible.
  • spatial filtering weights refers to the antenna weights that are applied at either the transmitter (gNB or UE) and the receiver (UE or gNB) for data/control transmission/reception. This term is more general in the sense that different propagation environments lead to different spatial filtering weights that match the transmission/reception of a signal to the channel. The spatial filtering weights may not always result in a beam in a strict sense.
  • DL beam management Prior to data transmission, a training phase is required in order to determine the gNB and the UE spatial filtering configurations. This is referred to in NR as DL beam management.
  • RSs reference signals
  • CSI-RS channel state information RS
  • SS/PBCH synchronization signal/physical broadcast control channel
  • DL RS downlink reference signal
  • CSI-RS can be used to find an appropriate beam pair link (BPL), meaning a suitable gNB transmit spatial filtering configuration (gNB transmit (Tx) beam) plus a suitable UE receive spatial filtering configuration (UE Rx beam) resulting in sufficiently good link budget.
  • BPL beam pair link
  • the gNB configures the UE to measure on a set of 5 CSI-RS resources (RSI, ..., RS5) which are transmitted with 5 different spatial filtering configurations (Tx beams).
  • the UE is also configured to report back the RS ID and the referencesignal receive power (RSRP) of the CSI-RS corresponding to the maximum measured RSRP.
  • the maximum measured RSRP corresponds to RS4. In this way, the gNB learns what is the preferred Tx beam from the UE perspective.
  • the gNB transmits a number of CSI-RS resources in different Orthogonal Frequency Division Multiplexing (OFDM) symbols all with the same spatial filtering configuration (Tx beam) as was used to transmit RS4 previously.
  • the UE tests a different Rx spatial filtering configuration (Rx beam) in each OFDM symbol in order to maximize the received RSRP.
  • the UE remembers the RS ID (RS ID 6 in this example) and the corresponding spatial filtering configuration that results in the largest RSRP.
  • the network can then refer to this RS ID in the future when DL data is scheduled to the UE, thus allowing the UE to adjust its Rx spatial filtering configuration (Rx beam) to receive the PDSCH.
  • the RS ID is contained in a transmission configuration indicator (TCI) that is carried in a field in the DCI that schedules the PDSCH.
  • TCI transmission configuration indicator
  • a PDSCH may be transmitted to a UE from multiple TRPs. Since different TRPs may be located in different physical locations and have different beams, the propagation channels can be different.
  • a UE may be configured by RRC with multiple TCI states.
  • a TCI state contains Quasi Co-location (QCL) information between the DMRS for PDSCH and one or two DL RSs such as NZP CSI-RS or SSB. Different NZP CSI-RS or SSB may be associated with different TRPs or beams.
  • QCL information can be used by a UE to apply large scale channel properties associated with the DL RSs (NZP CSI-RS or SSB) to DMRS of PDSCH for channel estimation and PDSCH reception.
  • a subset of the RRC configured TCI states may be activated by Medium Access Control Control Element (MAC CE) for PDSCH. From the activated TCI states, one or two of them may be dynamically selected and indicated in the DCI scheduling a PDSCH depending on over which TRP(s) or beam(s) the PDSCH is transmitted.
  • Each codepoint of the TCI field in DCI can indicate either 1 TCI state or two TCI states.
  • a TCI field codepoint indicating 1 TCI state can be used to transmit PDSCH from a single TRP or single beam. If a TCI field codepoint indicates 2 TCI states, then PDSCH can be transmitted from two TRPs or two beams. Note that in 6G this concept may be extended to the cases with more than two TRPs or two beams.
  • Simultaneous multi-TRP transmission with multi-panel reception can enable NC-JT in FR2.
  • An example is shown in Figure 1, where a PDSCH is sent to a UE 102 over two TRPs 104 and 106, with each TRP transmitting 2 layers.
  • the peak data rate to the UE can be increased as up to 4 aggregated layers from the two TRPs can be received by the UE.
  • CSI-RS resource indicators CRIs
  • SSBRIs SS/PBCH Block Resource Indicator
  • FIG. 2 shows an example scenario illustrating simultaneous multi-TRP transmission with multi -panel reception at the UE 102.
  • NZP CSI-RS resources #1 (202) and #2 (204) are transmitted from TRP1 104
  • NZP CSI-RS resources #3 (206) and #4 (208) are transmitted from TRP2 106.
  • the UE 102 is equipped with two panels.
  • the UE 102 may choose the two CRIs to be reported in one of the following ways:
  • Case 3 one CRI corresponds to TRP1 104 and the other CRI corresponds to TRP2 106 (e.g., NZP CSI-RS resources #1 202 and #3 206).
  • Case 1 If UE 102 reports the two CRIs according to either Case 1 or Case 2, then both beams reported correspond to the same TRP. In Cases 1 and 2, simultaneous multi-TRP transmission is not possible. Case 3 allows simultaneous multi-TRP transmission as the two beams reported correspond to different TRPs.
  • each beam group consists of two beams (i.e., 2 SSBRI /CRI values and corresponding Ll-RSRP), and where the two beams can be received simultaneously by the UE.
  • the UE can be configured with two channel measurement resource (CMR) sets, where each CMR set is associated to one TRP, and where the UE selects one CMR (i.e., one SSBRI/CRI) from each CMR set in each beam group.
  • CMR channel measurement resource
  • the existing RRC parameter CSI-AssociatedReportConfiglnfo is extended to be configured with two CMR resource sets.
  • the supported report format is shown in the table shown in Figure 3 (from Technical Specification (TS) 38.212).
  • the 1 -bit Resource set indicator is used to indicate if the strongest beam (i.e., CRI or SSBRI #1 of 1st resource group) belongs to the 1st or the 2nd CMR set.
  • Absolute RSRP (7 bits) is reported for the strongest beam, and differential RSRP (4 bits) is reported for the remaining beams.
  • the bitwidth of each SSBRI/CRI is determined based on the number of SSB/CSI-RS resources in the associated CMR resource set.
  • the present disclosure describes a method for providing group-based beam reporting for beams targeting multi-panel downlink (DL) reception or uplink (UL) transmission which mitigate the issue of inter-stream interference between communication of a UE and two or more different Transmission Reception Points (TRPs) at millimeter wave (mmWave)/terra-Hz frequencies.
