[0040] Principles and implementations of the present disclosure will be described in detail below with reference to the figures.
[0041] FIG. 1A, FIG. 1B and FIG. 1C illustrate schematic diagram of an example communication environment 100 in which example embodiments of the present disclosure can be implemented. In the communication environment 100, a plurality of communication devices, including a terminal device 110 and a network device 120, can communicate with each other.
[0042] In the example of FIG. 1A, FIG. 1B or FIG. 1C, the terminal device 110 may be a UE and the network device 120 may be a base station serving the UE. The serving area of the network device 120 may be called a cell 102.
[0043] As shown in FIG. 1B, the network device 120 may communicate with the terminal device 110 via at least one of the TRPs / panels 130-1, 130-2, 130-3 and 130-4. In the following text, the TRP / panel 130-1 may be also referred to as the first TRP / panel, the TRP / panel 130-2 may be also referred to as the second TRP / panel, the TRP / panel 130-3 may be also referred to as the third TRP / panel and the TRP / panel 130-4 may be also referred to as the fourth TRP / panel. Each of the TRPs / panels 130 may provide a plurality of beams for communication with the terminal device 110. It is noted that the number of TRPs / panels shown in FIG. 1B is only an example not limitation.
[0044] For example, the network device 120 may be configured with at least one of four TRPs / panels 130-1, 130-2, 130-3 and 130-4 (collectively referred to as TRPs 130 or individually referred to as TRP 130) . It is to be understood that the number of network devices, terminal devices and TRPs as shown in FIG. 1B is only for the purpose of illustration without suggesting any limitations to the present disclosure. The network 100 may include any suitable number of devices adapted for implementing embodiments of the present disclosure. Although not shown, it would be appreciated that one or more additional devices may be located in the cell 102, and one or more additional cells may be deployed in the communication environment 100. It is noted that although illustrated as a network device, the network device 120 may be another device than a network device. Although illustrated as a terminal device, the terminal device 110 may be other device than a terminal device. The term “TRP” refers to an antenna array (with one or more antenna elements) available to the network device located at a specific geographical location. For example, a network device may be coupled with multiple TRPs in different geographical locations to achieve better coverage. For another example, a network device may be implemented with multiple panels or multiple groups of antenna ports / elements in same geographical location. It is to be understood that the TRP can also be referred to as a “panel” , which also refers to an antenna array (with one or more antenna elements) or a group of antennas.
[0045] In the specific example of communication environment 100, a link from the terminal device 110 to the network device 120 is referred to as uplink, while a link from the network device 120 to the terminal device 110 is referred to as a downlink. Further, MIMO is supported in the communication environment 100. For example, the network device 120 and the terminal device 110 may communicate with each other via different beams to enable a directional communication. For another example, the network device 120 and the terminal device 110 may communicate with each other based on a plurality of antenna ports and / or a plurality of beams and / or a plurality of TCI states (e.g. a plurality of downlink TCI states and / or a plurality of joint TCI states and / or a plurality of uplink TCI states) . In downlink, the network device 120 is a transmitting (TX) device (or a transmitter) and the terminal device 110 is a receiving (RX) device (or a receiver) . In downlink, the network device 120 may transmit downlink transmission to the terminal device 110 via one or more beams or one or more TCI states (or downlink TCI states or joint TCI states) . For example, as illustrated in FIG. 1C, the network device 120 transmits downlink transmission to the terminal device 110 via a plurality of beams and / or a plurality of TCI states (e.g. a plurality of downlink TCI states and / or a plurality of joint TCI states) . Correspondingly, in uplink, the network device 120 is a RX device (or a receiver) and the terminal device 110 is a TX device (or a transmitter) . In uplink, the terminal device 110 may transmit uplink transmission to the network device 120 via one or more beams or one or more TCI states (or uplink TCI states or joint TCI states) . For example, as illustrated in FIG. 1C, the terminal device 110 transmits uplink transmission to the network device 120 via a plurality of beams and / or a plurality of TCI states (e.g. a plurality of uplink TCI states and / or a plurality of joint TCI states) .

The communication environment 100 may include any suitable number of devices configured to implementing example embodiments of the present disclosure. Although not shown, it would be appreciated that one or more additional devices may be located in the cell 102, and one or more additional cells may be deployed in the communication environment 100. It is noted that although illustrated as a network device, the network device 120 may be another device than a network device. Although illustrated as a terminal device, the terminal device 110 may be other device than a terminal device.

However, in some example embodiments, operations described in connection with a terminal device may be implemented at a network device or other device, and operations described in connection with a network device may be implemented at a terminal device or other device.
[0048] In some example embodiments, if the terminal device 110 is a terminal device and the network device 120 is a network device, a link from the network device 120 to the terminal device 110 is referred to as a downlink (DL) , while a link from the terminal device 110 to the network device 120 is referred to as an uplink (UL) . In DL, the network device 120 is a transmitting (TX) device (or a transmitter) and the terminal device 110 is a receiving (RX) device (or a receiver) . In UL, the terminal device 110 is a TX device (or a transmitter) and the network device 120 is a RX device (or a receiver) .
[0049] In some embodiments, the terminal device 110 and the network device 120 may communicate with each other via a channel such as a wireless communication channel on an air interface (e.g., Uu interface) .

In some embodiments, the number of CSI processing units (CPUs) occupied by the measurement report (e.g. for the second event or for the first event or for the third event) may be 2 or Q+1 or 1 (e.g. one for measurement of the second plurality of measurement resources, and the other one or the other Q for the measurement of the first plurality of measurement resources) .
[0221] In some embodiments, in case of the number of instance (s) is Q, (such as, for each measurement or assessment of the first plurality of measurement resources (e.g. for new beam) , an instance of measurement of the second plurality of measurement resources (or an instance of measurement of the second reference measurement resource or an instance of measurement of the first reference measurement resource (e.g. for current beam) is processed) , one instance for measurement of the second plurality of measurement resources may be based on the latest or nearest at least one transmission occasion of each of the second plurality of measurement resources (or the second reference measurement resource or the first reference measurement resource) (e.g. within the time window) . In some embodiments, the number of CPUs occupied by the measurement report (e.g. for the second event or for the first event or for the third event) may be 2 or Q+1 or 2*Q (e.g. one or Q for measurement of the second plurality of measurement resources (or the second reference measurement resource or the first reference measurement resource) , and the other one or the other Q for the measurement of the first plurality of measurement resources) . In some other embodiments, the CPUs for the measurement report (e.g. for the second event or for the first event or for the third event) may be occupied starting from the first symbol of the transmission occasion of the earliest one of the first plurality of measurement resources and the second plurality of measurement resources (and / or within the time window) .

For example, for the second event, the second reference measurement resource may be determined based on the TCI state (or the measurement resource corresponding to the TCI state) from the activated TCI states (e.g. the T TCI states) with H-th best quality, which needs comparison among measurement results of measurement resources corresponding to the activated TCI states (e.g. the T TCI states) or among the measurement results of measurement resources in the second plurality of measurement resources. The measurement resources associated with the activated TCI states (e.g. the T TCI states) may have same reference signal type (e.g. type of CSI-RS or type of SSB) .
[0223] In some embodiments, if first scheme (e.g. Scheme 1) configured, all the measurement resources associated with the activated TCI states (e.g. the T TCI states) or all the measurement resources in the second plurality of measurement resources and / or all the measurement resources in the first plurality of measurement resources may be CSI-RS resource (e.g. CSI-RS for beam management, e.g. CSI-RS resource configured with parameter repetition) or may be CSI-RS resource (e.g. CSI-RS for tracking, e.g. CSI-RS resource configured with parameter trs-info) . In some embodiments, if first scheme (e.g. Scheme 1) configured, the second reference measurement resource (or the first reference measurement resource) may be determined based on the TCI state (or the measurement resource corresponding to the TCI state) from a subset of activated TCI states (or the subset of the T TCI states) with H-th best quality. In some embodiments, the subset of activated TCI states (or the subset of the T TCI states) may be those TCI states configured with CSI-RS resource (e.g. CSI-RS for beam management, e.g. CSI-RS resource configured with parameter repetition) as QCL (e.g. with typeD, e.g. excluding the activated TCI state (s) configured with CSI-RS resource for tracking) . In some embodiments, if the number of the subset of activated TCI states (e.g. represented as Ts TCI states) is less than H (e.g. if Ts<H) , the TCI state (or the measurement resource corresponding to the TCI state) with Ts-th best quality (or the worst quality or the best quality or the 1st best quality) among the subset of activated TCI states (e.g. Ts TCI states) may be applied for the reference measurement resource (e.g. the first reference measurement resource or the second reference measurement resource) (e.g. current beam) . In some embodiments, Ts may be positive integer. In some embodiments, 1≤Ts≤T.

For example, may be resumed until number of activated TCI states is updated to be no less than the value of H (e.g. Ts≥H) . In some embodiments, if the number of (activated) TCI states (e.g. represented as Ts) is 1 (e.g. Ts=1) , the second reference measurement resource may be the measurement resource (e.g. in the second plurality of measurement resources) with 1st quality or best quality or min (Ts, H) -th best quality or Ts-th best quality of measurement result or the measurement resource corresponding to the indicated TCI state. In some embodiments, if the number of (activated) TCI states (e.g. represented as Ts) is 1 (e.g. Ts=1) , the event (e.g. the second event and / or the third event) may be changed to be first event or may be ignored or stopped or suspended. For example, may be resumed until number of activated TCI states is updated to be no less than the value of H (e.g. Ts≥H) .

In some embodiments, the second plurality of measurement resources may be based on the measurement resources (e.g. CSI-RS resources corresponding to qcl-type set to “typeD” ) configured as the QCL RS (or QCL RS resources) in the Ts TCI states. In some embodiments, the measurement resources in the second plurality of measurement resources may be the CSI-RS resources (e.g. corresponding to qcl-type set to “typeD” ) configured in the Ts TCI states. For example, in case of the first scheme is configured. For example, for the second event and / or for the third event.
[0227] In some embodiments, the second plurality of measurement resources may be based on the measurement resources (e.g. SSB resources) which are QCLed with the QCL RS (or QCL RS resources) (e.g. CSI-RS resources corresponding to qcl-type set to “typeD” configured) in the Ts TCI states (e.g. for the second event and / or for the third event) . (For example, in case of second scheme configured. For example, for the second event and / or for the third event.
[0228] In some embodiments, the number of measurement resources in the second plurality of measurement resources may be Ts. In some embodiments, if the number of measurement resources in the second plurality of measurement resources is less than the value of H or if Ts<H, the event (e.g. the second event and / or the third event) may be ignored or stopped or suspended. For example, may be resumed until number of measurement resources in the second plurality of measurement resources is updated to be no less than the value of H or until Ts≥H. In some embodiments, if number of measurement resources in the second plurality of measurement resources is 1 or if Ts=1, the second reference measurement resource may be the measurement resource (e.g. in the second plurality of measurement resources) with 1st quality or best quality or min (Ts, H) -th best quality or Ts-th best quality of measurement result or the measurement resource corresponding to the indicated TCI state. In some embodiments, if number of measurement resources in the second plurality of measurement resources is 1 or if Ts=1, the event (e.g. the second event and / or the third event) may be changed to be first event or may be ignored or stopped or suspended. For example, may be resumed until the number of measurement resources in the second plurality of measurement resources is updated to be no less than the value of H or until Ts≥H.

For example, the at least one configuration for the first event and / or the at least one configuration for the second event may be applied to configuration of the third event. In some embodiments, the cell index indicator (e.g. carrier indicator) in the at least one configuration may be applied to indicate which component carrier (CC) the indicated TCI state (e.g. current beam) is from, and the configured measurement resource (s) may be ignored or may not be measured for the third event.

In some embodiments, the field size for indication of CC index, cell index or report configuration ID of the measurement report or the (relative) index of the measurement report in the second number of measurement reports may be or or or S1 or S2 or S4. In some embodiments, the second number of measurement reports or report in the second uplink channel or the second uplink channel may comprise one or more of: indication of the third number of measurement report (s) (e.g. associated with event (s) ) which is triggered, or a bitmap of indication of the second number of measurement reports (wherein each bit may correspond to one measurement report, and the value of the bit may indicate whether the corresponding measurement report (e.g. associated with event) is triggered or not) .

[0333] Table 2
[0334] In some embodiments, for the measurement report (which is comprised in the second number of measurement reports or in the first number of measurement reports or associated with the first occasion of PUCCH occasion) with assessment not triggered (e.g. at the first PUCCH occasion) , the indication of whether the measurement report (or the associated event) is triggered or not is value 0 (or value 1) indicating the measurement report (or the associated event) is not triggered.
[0335] In this case, the network device can know which measurement report (or associated event or CC) is triggered among the second number of measurement reports or among the first number of measurement reports.
[0336] In some embodiments, the information bit of the at least one measurement report (or the uplink control information (UCI) bit sequence) (in the second uplink channel) may be represented as a0, a1, a2, a3, …, aA-1. In some embodiments, A may be the number of bits (or the payload size) of the at least one measurement report (or the UCI) in the second uplink channel. In some embodiments, A may be positive integer. In some embodiments, A>0 or 4≤A≤1024. In some embodiments, the measurement reports of all the second number of measurement reports are mapped to the bit sequence a0, a1, a2, a3, …, aA-1 starting with a0 (e.g. in the order from upper part to lower part in Table 3 or in the order from higher priority to lower priority or in the order from smaller priority value to larger priority value) . In some embodiments, the most significant bit of each measurement report is mapped to the lowest order information bit for that measurement report. For example, the most significant bit of the first measurement report is mapped to a0.
[0337] In some embodiments, the mapping order of the second number (e.g. S2) of measurement reports (e.g. transmitted or reported in the second uplink channel) may be based on whether the report configuration (s) (e.g. associated with event (s) ) is triggered or not firstly, and then based on the order of report configuration ID, cell (or CC) index.
[0338] In some embodiments, the mapping order of the second number (e.g. S2) of measurement reports (e.g. transmitted or reported in the second uplink channel) may be based on S3 measurement reports firstly (or mapped on upper part) and (S2-S3) measurement reports (or mapped on lower part) .
[0339] In some embodiments, the events associated with S3 measurement reports may be triggered (e.g. before the transmission of the second uplink channel or before the transmission of the associated occasion of first uplink channel or before the transmission of the associated first uplink channel) . In some embodiments, events associated with (S2-S3) measurement reports may be not be triggered (e.g. before the transmission of the second uplink channel or before the transmission of the associated occasion of first uplink channel or before the transmission of the associated first uplink channel) . In some embodiments, S3 may be positive integer or non-negative integer. In some embodiments, 1≤S3≤ S2 or 0≤S3≤ S2.
[0340] In some embodiments, the S3 measurement reports may be the third number of measurement reports with associated event (s) triggered. In some embodiments, the S3 measurement reports may be same as or a subset of the second number of measurement reports. In some embodiments, the S3 measurement reports may be same as or a subset of the first number of measurement reports.
[0341] In some embodiments, the S3 measurement reports may be associated with a same priority value. For example, the S3 measurement reports may have same priority. In some embodiments, the priority value for the S3 measurement reports may be based on the smallest one priority value among those calculated for the S3 measurement reports (or S3 report configurations) . In some embodiments, the priority value for the S3 measurement reports may be based on the largest one priority value among those calculated for the S3 measurement reports (or S3 report configurations) . In some embodiments, the priority value for the S3 measurement reports may be based on the smallest value of report configuration ID among the S3 measurement reports (or S3 report configurations) . In some embodiments, the priority value for the S3 measurement reports may be based on the smallest value of cell index among the S3 measurement reports (or S3 report configurations) . In some embodiments, the priority value for the S3 measurement reports may be based on the largest value of report configuration ID among the S3 measurement reports (or S3 report configurations) . In some embodiments, the priority value for the S3 measurement reports may be based on the largest value of cell index among the S3 measurement reports (or S3 report configurations) .
[0342] In some embodiments, the S2 measurement reports may be associated with a same priority value. For example, the S2 measurement reports may have same priority. In some embodiments, the priority value for the S2 measurement reports may be based on the smallest one priority value among those calculated for the S2 measurement reports (or S2 report configurations) . In some embodiments, the priority value for the S2 measurement reports may be based on the largest one priority value among those calculated for the S2 measurement reports (or S2 report configurations) . In some embodiments, the priority value for the S2 measurement reports may be based on the smallest value of report configuration ID among the S2 measurement reports (or S2 report configurations) . In some embodiments, the priority value for the S2 measurement reports may be based on the smallest value of cell index among the S2 measurement reports (or S2 report configurations) . In some embodiments, the priority value for the S2 measurement reports may be based on the largest value of report configuration ID among the S2 measurement reports (or S2 report configurations) . In some embodiments, the priority value for the S2 measurement reports may be based on the largest value of cell index among the S2 measurement reports (or S2 report configurations) .
[0343] In some embodiments, the S2-S3 measurement reports may be associated with a same priority value. For example, the S2-S3 measurement reports may have same priority. In some embodiments, the priority value for the S2-S3 measurement reports may be based on the smallest one priority value among those calculated for the S2-S3 measurement reports (or S2 report configurations) . In some embodiments, the priority value for the S2-S3 measurement reports may be based on the largest one priority value among those calculated for the S2-S3 measurement reports (or S2-S3 report configurations) .

[0344] In some embodiments, Table 3 below show an example of one measurement report. In some embodiments, subset or all of the rows in Table 3 may be applied.
[0345] Table 3
[0346] In some embodiments, the priority (from higher priority to lower priority) of the second number of reported measurement reports may be based on the order (from upper part to lower part) in Table 3. In some embodiments, the priority value (from smaller priority value to larger priority value) of the second number of reported measurement reports may be based on the order (from upper part to lower part) in Table 3.
[0347] In this case, the network device can know which measurement report (or associated event or CC) is triggered among the second number of measurement reports or among the first number of measurement reports.
[0348] In some embodiments, the S2-S3 measurement reports may be measured based on the latest timing (or latest time window) among those for the S3 measurement reports.
[0349] In some embodiments, the priority of the second number of measurement reports (e.g. reported measurement reports in the second uplink channel) may be based on whether the event (s) associated with the CSI report configuration (s) is triggered or not firstly, and then based on the order of CSI report configuration ID, cell (or CC) index.
[0350] In some embodiments, a first report is said to have higher priority over a second report if the associated priority value is lower for the first report than for the second report. In some embodiments, if a first priority value associated with a first report is smaller or lower than a second priority value associated with a second report, the priority of the first report is higher than the priority of the second report.
[0351] In some embodiments, in case of multiple reports overlapped in time domain, the report (s) associated with lower priority or associated with larger priority value (s) may be dropped.
[0352] In some embodiments, the event (s) associated with measurement report (s) (or the report configuration (s) ) which is triggered may be represented as S3 measurement report (s) (or S3 report configuration (s) ) . For example, the S3 measurement report (s) may be same or subset of the second number of measurement report (s) . For example, the number of measurement report (s) (or the report configuration (s) ) may be S3. In some embodiments, the S3 measurement report (s) (or S3 report configuration (s) ) are associated with a priority value PriiCSI (y, k, c, s) =2·Ncells·Ms·y+Ncells·Ms·k+Ms·c+s, wherein y=0 and / or k=0 (e.g. for both mode A and mode B) , and s may be the report configuration ID (e.g. of the S3 report configuration (s) , e.g. associated with event triggered, e.g. excluding those report configuration (s) associated with event not triggered) .
[0353] In some embodiments, the event (s) associated with the measurement report (s) (or the report configuration (s) ) which is not triggered may be represented as S2-S3 measurement report (s) (or S2-S3 report configuration (s) ) . For example, the S2-S3 measurement reports may be same or subset of the second number of measurement report (s) . For example, the number of measurement report (s) (or the report configuration (s) ) may be S2-S3. In some embodiments, the S2-S3 measurement report (s) (or S2-S3 report configuration (s) ) are associated with a priority value PriiCSI (y, k, c, s) =2·Ncells·Ms·y+Ncells·Ms·k+Ms·c+s, wherein y=0 and / or k=0 (e.g. for both mode A and mode B) , and s may be the report configuration ID (e.g. of the S2-S3 report configuration (s) , e.g. associated with event not triggered, e.g. excluding those report configuration (s) associated with event triggered) .
[0354] In some embodiments, any associated priority value of the S3 measurement report (s) (or S3 report configuration (s) ) (e.g. in the second number of measurement reports) are smaller than any associated priority value of the S2-S3 measurement report (s) (or S2-S3 report configuration (s) ) (e.g. in the second number of measurement reports) . In some embodiments, each one of the S3 measurement report (s) (or S3 report configuration (s) ) (e.g. in the second number of measurement reports) may have higher priority than any one of the S2-S3 measurement report (s) (or S2-S3 report configuration (s) ) (e.g. in the second number of measurement reports) .
[0355] In some embodiments, the events associated with S3 measurement reports may be triggered (e.g. before the transmission of the second uplink channel or before the transmission of the associated occasion of first uplink channel or before the transmission of the associated first uplink channel) . In some embodiments, events associated with (S2-S3) measurement reports may be not be triggered (e.g. before the transmission of the second uplink channel or before the transmission of the associated occasion of first uplink channel or before the transmission of the associated first uplink channel) . In some embodiments, S3 may be positive integer or non-negative integer. In some embodiments, 1≤S3≤ S2 or 0≤S3≤ S2.
[0356] In some embodiments, the measurement reports associated with event (and / or with associated event triggered) may have lower priority than measurement report for layer-1 triggered mobility (LTM) . In some embodiments, if there is measurement report (s) for LTM, the at least one measurement report (or the at least one report configuration, e.g. associated with event) or the assessment of the at least one report configuration may be suspended or the at least one measurement report associated with event may be dropped. For example, the transmission occasion of the at least one measurement report may be overlapped with the transmission occasion of the measurement report (s) for LTM. For example, the at least one measurement report may be the first number of measurement reports or the second number of measurement reports.
[0357] In some embodiments, the measurement reports associated with event (and / or with associated event triggered) may have higher priority than the measurement report (s) for LTM. In some embodiments, the measurement reports associated with event (and / or with associated event not triggered) may have lower priority than the measurement report (s) for LTM.
[0358] In this case, the measurement report (s) associated with event triggered will be allocated with higher priority, which can be ensured to be transmitted firstly.
[0359] In some embodiments, the at least one measurement report may comprise: a first measurement report (e.g., for coherent joint transmission (CJT) calibration) and a second measurement report (e.g., for CSI report or for CJT CSI report) . In some embodiments, the at least one measurement report may be one measurement report, and the one measurement report may comprise: a first subset of the measurement report (e.g., for CJT calibration, e.g. delay offset reporting and / or frequency offset reporting and / or phase offset reporting) and a second subset of the measurement report (e.g., for CSI report) .
[0360] In some embodiments, the first measurement report and / or the first subset of the measurement report may comprise or may be associated with one or more of: delay offset report, report quantity configured as “cjtc-Dd” , frequency offset report, report quantity configured as “cjtc-F” , phase offset report, report quantity configured as “cjtc-P” , delay offset report + frequency offset report, or report quantity configured as “cjtc-Dd-F” .
[0361] In some embodiments, the second measurement report and / or the second subset of the measurement report may comprise or may be associated with one or more of: CSI report, PMI report, rank indicator (RI) report, CQI report, CSI-RS resource indicator (CRI) report, SSB resource indicator (SSBRI) report, layer indicator (LI) report, codebook indicator (s) report, precoder report, channel measurement report, report quantity configured as one or more of: “cri-RI-PMI-CQI” , “cri-RI-LI-PMI-CQI” , “cri-RI-i1” , “cri-RI-CQI” , “cri-RI-i1-CQI” , “cri-RSRP” , “ssb-Index-RSRP” , “cri-SINR” , “ssb-Index-SINR” , “cri-RSRP-Index” , “ssb-Index-RSRP-Index” , “cri-SINR-Index” , “ssb-Index-SINR-Index” or “tdcp” .
[0362] In some embodiments, the terminal device may receive an indication (e.g. in DCI) , and the terminal device may transmit the first measurement report (e.g. coherent joint transmission (CJT) calibration report, e.g. for delay offset or for frequency offset) and the second measurement report (e.g. CSI report or CJT CSI report) based on the indication. In some embodiments, the indication may be a CSI trigger state or a value in CSI request field. In some embodiments, the first measurement report and the second measurement report may be in the second uplink channel or in the PUSCH scheduled by the DCI. In some embodiments, the second measurement report may be based on the pre-compensation with the reported delay offset (and / or reported frequency offset) comprised in the first measurement report.
[0363] In some embodiments, the at least one configuration may comprise at least one of the following: an indication of whether the second measurement report based on pre-compensation with the reported delay offset and / or frequency offset and / or phase offset comprised in the first measurement report, an indication of whether the first measurement report and the second measurement report support to be triggered by a same message or a same DCI, an indication of whether a time offset between transmitting the first measurement report and the second measurement report is smaller than or equal to a fifth threshold, an indication of whether the first measurement report and the second measurement report are to be transmitted on a same uplink resource, an indication of whether the first measurement report and the second measurement report are jointly reported or separately reported, an indication of whether pre-compensation based on the reported delay offset and / or frequency offset and / or phase offset in the first measurement report is applied in time domain or in frequency domain, an indication of a resolution for applying pre-compensation based on the reported delay offset and / or frequency offset and / or phase offset in the first measurement report, the resolution comprising a frequency domain unit and / or a time domain unit.
[0364] In some embodiments, in case of the first measurement report (e.g. CJT calibration) and the second measurement report (e.g. CJT CSI) are jointly triggered (e.g. by the indication in the DCI) (e.g. the first measurement report and the second measurement report to be transmitted in the same report instance) , the first measurement report and the second measurement report may be regarded or considered as a whole. In some embodiments, the first measurement report and the second measurement report may be associated with a same priority value (e.g. one same priority is determined for the first measurement report and the second measurement report) .
[0365] In some embodiments, the terminal device may receive indication (e.g. CSI request field or a CSI trigger state) in DCI triggering the first measurement report (e.g. CJT calibration report) and the second measurement report (e.g. CJT CSI report) , the first measurement report and the second measurement report may be associated with a same priority value. In some embodiments, the maximum or minimum value between the first report configuration ID (e.g. associated with the first measurement report) and the second report configuration ID (e.g. associated with the second measurement report) may be applied to determine the priority value for the first measurement report and the second measurement report. In some embodiments, the maximum or minimum value between a first priority value (e.g. calculated based on the first report configuration ID (e.g. associated with the first measurement report) ) and a second priority value (e.g. calculated based on the second report configuration ID (e.g. associated with the second measurement report) ) may be applied to determine the priority value for the first measurement report and the second measurement report.
[0366] In some embodiments, the priority value (e.g. represented as PriiCSI (y, k, c, s) ) may be calculated based on PriiCSI (y, k, c, s) =2·Ncells·Ms·y+Ncells·Ms·k+Ms·c+s.
[0367] In some embodiments, y=0 for aperiodic measurement reports (e.g. CSI reports) to be carried on PUSCH and / or y=1 for semi-persistent measurement reports (e.g. CSI reports) to be carried on PUSCH and / or y=2 for semi-persistent measurement reports (e.g. CSI reports) to be carried on PUCCH and / or y=3 for periodic measurement reports (e.g. CSI reports) to be carried on PUCCH.
[0368] In some embodiments, k=0 for measurement reports (e.g. CSI reports) carrying L1-RSRP or L1-SINR and / or k=1 for measurement reports (e.g. CSI reports) not carrying L1-RSRP or L1-SINR.
[0369] In some embodiments, for the first measurement report and / or the second measurement report the value of y may be 0. In some embodiments, for the first measurement report and / or the second measurement report the value of k may be 1.
[0370] In some embodiments, for the at least one measurement report (e.g. associated with event) , the value of y may be 0. In some embodiments, for the at least one measurement report (e.g. associated with event) , the value of k may be 0. In some embodiments, for the first information (e.g. in the first uplink channel) , the value of y may be 0 or 2. In some embodiments, for the first information (e.g. in the first uplink channel) , the value of k may be 0 or 1.
[0371] In some embodiments, c may be the serving cell index. In some embodiments, for the at least one measurement report (e.g. associated with event or associated with the first type) , c may be the serving cell index where the at least one measurement report (or the at least one report configuration (e.g. associated with event or associated with the first type or associated with UE initiated or event driven report) ) is configured or the serving cell index where the at least one measurement report (e.g. corresponding to the at least one report configuration) is transmitted. In some embodiments, Ncells may be the value of the higher layer parameter maxNrofServingCells. In some embodiments, s may be the report configuration ID (e.g. for each of the at least one report configuration) . In some embodiments, Ms may be the value of the higher layer parameter maxNrofCSI-ReportConfigurations or maxNrofUEI-CSI-ReportConfigurations. In some embodiments, Ms may be positive integer. In some embodiments, 1≤Ms≤16 or 1≤Ms≤32 or 1≤Ms≤64. In some embodiments, Ms may be one or more of: 8, 16, 32, 64.
[0372] In some embodiments, in case of the first measurement report (e.g. CJT calibration report) is dropped, the linked second measurement report (e.g. CJT CSI report) may be dropped together. In some embodiments, in case of the first measurement report (e.g. CJT calibration report) is dropped, the linked second measurement report (e.g. CJT CSI report) may be calculated without pre-compensation (or may be calculated based on pre-compensation with a previous first measurement report (e.g. with CJT calibration report (e.g. within valid duration or if valid) ) .
[0373] In some embodiments, in case of one of the first measurement report (e.g. CJT calibration report) and the second measurement report (e.g. CJT CSI report) needs to be dropped, the second measurement report (e.g. CJT CSI report) will be dropped firstly (e.g. regardless of the priority values between the first measurement report and the second measurement report) .
[0374] In some embodiments, the timeline for the first measurement report and the second measurement report in the second uplink channel may be (Z2, Z′2) or (Z2+Z′2, 2*Z′2) or (Z2+Zo, Z′2+Zo) or (Z2+Z′2+Zo, 2*Z′2+Zo) . In some embodiments, (Z2, Z′2) may be (40, 37) or (72, 69) or (141, 140) or (150, 140) or (608, 560) or (1216, 1120) . In some embodiments, Z2 may be 40 or 72 or 141 or 150 or 608 or 1216. In some embodiments, Z′2 may be 37 or 69 or 140 or 560 or 1120. In some embodiments, Zo may be 0. In some embodiments, Zo may be integer. In some embodiments, 1≤Zo≤1216 or 1≤Zo≤1120 or 1≤Zo≤140.
[0375] In some embodiments, the terminal device may receive a first scaling factor configuration for number of layer is 1 (or for rank indicator (RI) =1) and a second scaling factor configuration for number of layer is 2 (or for RI=2) from the network device, the terminal device may transmit value of RI and at least one codebook indicator (e.g. in at least one measurement report) to the network device based on at least one of the first scaling factor and the second scaling factor. In some embodiments, the terminal device may apply the first scaling factor configuration in case of the value of reported RI is 1. In some embodiments, the terminal device may apply the first scaling factor configuration in case of the value of reported RI is 2 (e.g. two layers associated with the at least one codebook indicator) and one same vector (e.g. spatial domain (SD) basis vector) is applied for the two layers. In some embodiments, the terminal device may apply the second scaling factor configuration in case of the value of reported RI is 2 (e.g. two layers associated with the at least one codebook indicator) and two different vectors (e.g. SD basis vectors) are applied for the two layers.
[0376] In some embodiments, the first plurality of measurement resources are configured in a CSI-RS resource set (e.g. NZP-CSI-RS-ResourceSet) , wherein the CSI-RS resource set is configured with the higher layer parameter repetition set to ‘OFF’ .
[0377] In some embodiments, regarding the reference measurement resource (e.g. the first reference measurement resource and / or the second reference measurement resource) , the terminal device may receive configuration of either the first scheme or the second scheme from the network device. In some embodiments, the terminal device may receive configuration of the first plurality of measurement resources from the network device. In some embodiments, if measurement resources in the first plurality of measurement resources are configured as CSI-RS or if the first plurality of measurement resources is configured as a CSI-RS resource set (e.g. configured with repetition) , the first scheme is applied or the reference measurement resource is the QCL RS (or QCL RS resource) (e.g. with QCL type as typeD) (e.g. a CSI-RS resource) configured in the indicated TCI state or in one of the activated TCI states. For example, the first reference measurement resource may be the QCL RS (or QCL RS resource) (e.g. with QCL type as typeD) (e.g. a CSI-RS resource) configured in the indicated TCI state. For another example, the second reference measurement resource may be one of the second plurality of measurement resources configured as the QCL RS (or QCL RS resources) (e.g. with QCL type as typeD) (e.g. a CSI-RS resource) configured in the T TCI states. In some embodiments, the reference measurement resource may include or may be the RS resource (or RS resource index or CSI-RS resource or CSI-RS resource index) with same value as the RS (e.g. the CSI-RS) index (e.g. in the RS sets or corresponding to the RS with qcl-type set to “typeD” ) in the indicated TCI state or in one of the T TCI states. In some embodiments, the reference measurement resource may include or may be the RS resource (or RS resource index or CSI-RS resource or CSI-RS resource index) configured with qcl-type set to “typeD” ) in the indicated TCI state or in one of the T TCI states.
[0378] In some embodiments, if measurement resources in the first plurality of measurement resources are configured as SSB or if the first plurality of measurement resources is configured as a set of SSB resources, the second scheme is applied or the reference measurement resource is a SSB resource configured in the indicated TCI state or in one of the activated TCI states. For example, the reference measurement resource may be an SSB resource which is quasi-colocated (QCLed) with the QCL RS (or QCL RS resource) (e.g. with QCL type as typeD) (e.g. a CSI-RS resource) in the indicated TCI state (or in one of the T TCI states) . For example, the first reference measurement resource may be an SSB resource which is quasi-colocated (QCLed) with the QCL RS (or QCL RS resource) (e.g. with QCL type as typeD) (e.g. a CSI-RS resource) in the indicated TCI state. For example, the second reference measurement resource may be one of the second plurality of measurement resources (e.g. SSB resources) which are QCLed with the QCL RS (or QCL RS resources) (e.g. CSI-RS resources corresponding to qcl-type set to “typeD” configured) in one of the T TCI states. For example, the second plurality of measurement resources (e.g. SSB resources) may be SSB resources which are QCLed with the QCL RS (or QCL RS resources) (e.g. CSI-RS resources corresponding to qcl-type set to “typeD” ) configured in the T TCI states (e.g. for the second event and / or for the third event) . In some embodiments, the QCL RS (or QCL RS resource) may be a CSI-RS (or a CSI-RS resource) corresponding to qcl-type set to “typeD” in the indicated TCI state.
[0379] In this case, the terminal device only needs to trigger beam report when the new beam RS resources are for different Tx beams
[0380] In some embodiments, if repetition set to 'on' for the first plurality of measurement resources (e.g. the CSI-RS resource set) , there is no need for the terminal device to report any beam information to network device since the beam from the network device is not changed.
[0381] In some embodiments, if the terminal device is configured with a NZP-CSI-RS-ResourceSet configured with the higher layer parameter repetition set to 'on' , the terminal device may assume that the CSI-RS resources, within the NZP-CSI-RS-ResourceSet are transmitted with the same downlink spatial domain transmission filter (e.g. where the CSI-RS resources in the NZP-CSI-RS-ResourceSet are transmitted in different Orthogonal Frequency Division Multiplexing (OFDM) symbols) . In some embodiments, if a terminal device is configured with a NZP-CSI-RS-ResourceSet configured with the higher layer parameter repetition set to 'off' , the terminal device shall not assume that the CSI-RS resources within the NZP-CSI-RS-ResourceSet are transmitted with the same downlink spatial domain transmission filter.
[0382] In some embodiments, the first plurality of measurement resources are configured in a CSI-RS resource set (e.g. NZP-CSI-RS-ResourceSet) configured with the higher layer parameter ‘repetition’ set to ‘OFF’ , and the NZP-CSI-RS-ResourceSet may be received as part of one report configuration (e.g. UE initiated or event trigger beam report configuration) ; and / or associated with a measurement report (or a report configuration) with report type set to the first type (e.g. ‘event trigger’ or ‘UE initiated’ ) ; and / or associated with a CSI trigger state associated with the at least one report configuration or a special CSI trigger state or a special codepoint of CSI request field configured for UE initiated or event trigger beam report; and / or associated with the first uplink channel (e.g. PUCCH) , which is also associated with the second uplink channel (e.g. CG PUSCH) .
[0383] In some embodiments, the higher layer parameter ‘repetition’ is not present for the first plurality of measurement resources or the CSI-RS resource set (e.g. NZP-CSI-RS-ResourceSet) .
