For example, the at least one TCI state may be downlink TCI state or joint TCI state or downlink-Or-Joint-TCI-State. The terminal device 110 may also communicate data and control information to the network device 120 via a plurality of beams (also referred to as “UL beams” ) or based on at least one spatial relation information or based on at least one TCI state. For example, the at least one TCI state may be uplink TCI state or joint TCI state or downlink-Or-Joint-TCI-State. In some example embodiments, a beam is also defined and indicated by parameters of a transmission configuration indicator. For example, there may be a transmission configuration indicator (TCI) field in DCI. A value of the TCI field may be referred to as a “TCI codepoint” . In some embodiments, a TCI codepoint may indicate or comprise one or more TCI states. For example, one TCI codepoint may indicate one or two downlink TCI states. For another example, one TCI codepoint may indicate one or two uplink TCI states. For another example, one TCI codepoint may indicate one or two joint TCI states.

The quasi co-location relationship may be configured by the higher layer parameter qcl-Type1 for the first downlink (DL) RS, and qcl-Type2 for the second DL RS (if configured) . For the case of two DL RSs, the QCL types may not be the same, regardless of whether the references are to the same DL RS or different DL RSs.

The UE is not expected to receive more than 8 TCI states in the activation command.In some embodiments, when the DCI field 'Transmission Configuration Indication' is present in DCI format 1_2 and when the number of codepoints S in the DCI field 'Transmission Configuration Indication' of DCI format 1_2 is smaller than the number of TCI codepoints that are activated by the activation command, as described in clause 6.1.3.14 and 6.1.3.24 of [10, TS38.321] , only the first S activated codepoints may be applied for DCI format 1_2.In some embodiments, when the UE may transmit a PUCCH with HARQ-ACK information in slot n corresponding to the PDSCH carrying the activation command, the indicated mapping between TCI states and codepoints of the DCI field 'Transmission Configuration Indication' should be applied starting from the first slot or the first subslot that is after slotwhere μ is the SCS configuration for the PUCCH. If tci-PresentInDCI is set to 'enabled' or tci-PresentDCI-1-2 is configured for the CORESET scheduling the PDSCH, and the time offset between the reception of the DL DCI and the corresponding PDSCH is equal to or greater than timeDurationForQCL if applicable, after a UE receives an initial higher layer configuration of TCI states and before reception of the activation command, the UE may assume that the DM-RS ports of PDSCH of a serving cell are quasi co-located with the synchronization signal / physical broadcast channel (SS / PBCH) block determined in the initial access procedure with respect to qcl-Type set to 'typeA' , and when applicable, also with respect to qcl-Type set to 'typeD' .In some embodiments, the measurement report may include at least one indication of a first number of resources in the group of resources.

For example, the value “0” in the field may indicate that the at least one CSI-RS resource and / or SSB is not applied, and the value “1” in the field may indicate that the at least one CSI-RS resource and / or SSB is applied.In some embodiments, the at least one CSI-RS resource and / or SSB may replace QCL source / reference RS in TCI states mapping to TCI codepoints based on ascending / descending order. For example, TCI codepoint 0 may correspond to the CSI-RS resource with highest RSRP / SINR.In some embodiments, the confirmation may be indicated by the TCI field in a DCI. In some embodiments, the TCI field may include or comprise or map to a first set of codepoints corresponding to the TCI states (e.g. activated by MAC CE or a first set of TCI states or a previous set of TCI states) , and a second set of codepoints corresponding to a second set of TCI states associated with or corresponding to the at least one CSI-RS resource and / or SSB (e.g. in the measurement report or in the latest measurement report or in the confirmed measurement report) for QCL reference (e.g. QCL typeD and / or QCL typeA and / or QCL typeC) in the measurement report.

Alternatively, if the terminal device 110 receives (2055) one TCI codepoint in the first set, the terminal device 110 may determine (2060) that the measurement report may be applied, and the at least one CSI-RS and / or SSB may be applied as QCL reference for TCI states mapping to the first set of TCI codepoints. The indicated TCI state may be applied (2060) after beam application timing, and the TCI states in the first set of TCI codepoints may be changed to be activated TCI states, (the second set of TCI codepoints may be reserved) .In some embodiments, there may be a first codepoint in the TCI state configured as reserved. In some embodiments, after transmission of a measurement report, if the terminal device 110 receives the first codepoint, a TCI state with QCL reference as the reported CSI-RS resource and / or SSB may be applied, and the codepoint corresponding to previous indicated TCI state may be reserved. In some embodiments, if the terminal device 110 receives a codepoint different from the first codepoint, the measurement report may not be applied, and the first codepoint may remain reserved.For example, the at least one CSI-RS resource may replace one or two RS (at least the RS for QCL typeD) in the RS sets of the activated TCI states (or the indicated TCI state) . As another example, the at least one SSB may replace the QCL reference (e.g. QCL typeD and / or QCL type C) for a set of CSI-RS resource (e.g. configured for beam management or configured with trs-info and / or configured with QCL source to be the first SSB) .In some embodiments, the indication may also indicate one of the at least one CSI-RS resource and / or SSB to be applied. In some embodiments, the reported CSI-RS resource may be applied as QCL source (e.g. QCL typeD and / or QCL typeA and / or QCL typeC) for TCI state for DL. In some embodiments, the reported CSI-RS resource may be applied to determine uplink spatial filter and / or as pathloss reference RS for UL.In some embodiments, if the measurement report is transmitted and / or if the confirmation for the measurement report is received, the terminal device 110 may set the beam failure instance (BFI) counter to be 0. In some embodiments, the RSRP and / or SINR may be filtered based on M times L1 measurement. In some embodiments, M may be positive integer.
