AI Technical Summary
Existing communication systems face challenges in optimizing carrier-specific scaling factor (CSSF) and reducing measurement delay by requiring measurements on multiple component carriers (CCs), particularly in scenarios where only one CC is measured per frequency range.
A terminal device receives a configuration for measurement and reporting of a group of CCs from a network device, measures a first CC within the group, and transmits a measurement report based on this measurement, enabling measurement reporting for the entire group, thereby optimizing CSSF and reducing measurement delay.
This approach allows for efficient measurement reporting across a group of CCs with optimized CSSF and shorter measurement delays, enhancing flexibility and accuracy in communication networks.

[0037] Principles and embodiments of the present disclosure will be described in detail below with reference to the accompanying drawings. Reference is first made to Fig. 1, which illustrates an example communication system 100 in which embodiments of the present disclosure may be implemented. The system 100 includes a network device 110. The network device 110 serves a primary cell (PCell) 130, and several secondary cell (SCell) , for example, SCell 140, 150, and 160. The system 100 also includes one or more terminal devices, such as terminal devices 120, and 121. The terminal devices 120, 121 are capable of connecting and communicating in an UL and DL with the network device 110. In communication systems, an UL refers to a link in a direction from a terminal device to a network device, and a DL refers to a link in a direction from the network device to the terminal device.
[0038] It is to be understood that the number of network device, terminal devices and cells is only for the purpose of illustration without suggesting any limitations. The system 100 may include any suitable number of network device, terminal devices and cells adapted for implementing embodiments of the present disclosure.
[0039] Communications in the communication system 100 may be implemented according to any proper communication protocol (s) , comprising, but not limited to, cellular communication protocols of the first generation (1G) , the second generation (2G) , the third generation (3G) , the fourth generation (4G) and the fifth generation (5G) and on the like, wireless local network communication protocols such as Institute for Electrical and Electronics Engineers (IEEE) 802.11 and the like, and / or any other protocols currently known or to be developed in the future. Moreover, the communication may utilize any proper wireless communication technology, comprising but not limited to: code division multiple access (CDMA) , frequency division multiple access (FDMA) , time division multiple access (TDMA) , frequency division duplex (FDD) , time division duplex (TDD) , multiple-input multiple-output (MIMO) , orthogonal frequency division multiple (OFDM) , discrete Fourier transform spread OFDM (DFT-s-OFDM) and / or any other technologies currently known or to be developed in the future.
[0040] Each of the cells may correspond to a component carrier (CC) . The terminal device may measure CCs and transmit measurement report to the network device. Reference is now made to Fig. 2, which shows an example 200 of measurement on CCs according to some embodiments of the present disclosure. In order to reduce carrier-specific scaling factor (CSSF) , minimizing measurements on serving CCs is expected. For example, as shown in Fig. 2, the terminal device 120 is configured with frequency range (FR) 1+FR2 carrier aggregation (CA) , where PCell is in FR1 and two SCells operating on CC2 and CC3 respectively are within the same FR2 band. The terminal device 120 may measure only one serving CC e.g. CC2 per frequency range (FR) 2 band as in Fig. 2. However, as not all CCs are measured, a problem of measurement reporting is induced.
[0041] Among others, an issue addressed by some embodiments of the present disclosure is how to enable the terminal device to trigger measurement reporting irrespective of which CC is being measured within a same band.
[0042] According to embodiments of the present disclosure, there is provided a solution for measurement reporting. In an aspect of the solution, a terminal device receives, from a network device, a configuration of measurement and reporting for a group of CCs. The terminal device measures a first CC in the group of CCs. The terminal device transmits, to the network device, a measurement report for the group of CCs based on the measurement of the first CC. This solution may enable the terminal device to trigger measurement reporting for a group of CCs based on measurement of one CC. With only one CC measured per group, CSSF may be optimized and measurement delay may be shorter.
[0043] Reference is now made to Fig. 3, which shows a process 300 for measurement reporting according to some embodiments of the present disclosure. For the purpose of discussion, the process 300 will be described with reference to Fig. 1. The process 300 may involve the terminal device 120 and the network device 110 as illustrated in Fig. 1.
[0044] At 310, the network device 110 may transmit, to the terminal device 120, a configuration of measurement and reporting for a group of CCs. Accordingly, the terminal device 120 may receive the configuration from the network device 110.
[0045] In some embodiments, the group of CCs may comprise CCs in a FR2 band. The group of CCs may comprise all CCs or all serving CCs in a FR2 band. In this case, “per group” may also be referred to as “per band” . In some other embodiments, the group of CCs may comprise CCs that are contiguous in a FR1 band. In some other embodiments, the group of CCs may comprise CCs configured by the network device 110, or in other frequency ranges. It is to be understood that channels may be assumed to be same for a FR2 band, so that CCs in a FR2 band may form a group. Similarly, channels may not be assumed to be same for FR1 intra-band non-contiguous carriers, but may be same for contiguous carriers in a band, so that CCs that are contiguous in a FR1 band may form a group. It is also possible that the network device 110 may configure a number of CCs as a group. These carriers may be in different bands or different frequency ranges but may be collocated so that channels may be assumed the same.
[0046] In some embodiments, the configuration may comprise at least a per group measurement identity associated with a reporting configuration. The reporting configuration may comprise a reporting condition or event.
[0047] In some embodiments, the configuration may further comprise an indication of a measurement object (MO) associated with the group of CCs which is called a per group MO. The per group measurement identity may link the per group MO with the reporting configuration. For example, the configuration may comprise a per group MO index (ID) and a report configuration ID related to the per group measurement identity.
[0048] In some embodiments, the indication of the per group MO may comprise a list of at least one serving cell index associated with the group of CCs, a list of at least one synchronization signal block (SSB) frequency value (center frequency of SSB) associated with the per group MO, a list of at least one absolute radio-frequency channel number (ARFCN) value associated with the per group MO, an index of a band associated with the group of CCs, an index of a band in a band combination associated with the group of CCs, or any combination thereof.
[0049] In some other embodiments, the configuration may further comprise a group of MOs corresponding to the group of CCs, an indication of a per group MO associated with the group of MOs, or any combination thereof. Each of the group of MOs may correspond to one CC in the group of CCs. In some embodiments, the group of MOs may be a group of serving cell MOs. The per group measurement identity may link the per group MO with the reporting configuration. For example, the configuration may comprise a per group MO ID and a report configuration ID related to the per group measurement identity.
[0050] In some other embodiments, the configuration may further comprise a group of MOs corresponding to the group of CCs. In some embodiments, the group of MOs may be a group of serving cell MOs. The per group measurement identity may link the group of MOs with the reporting configuration. For example, the configuration may comprise the group of MOs and a report configuration ID related to the per group measurement identity.
[0051] At 320, the terminal device 120 may measure a first CC in the group of CCs. In some embodiments, the terminal device 120 may select the first CC based on UE selection, network indication, a specified rule in a specification, or any other rules. For instance, the terminal device 120 may select primary component carrier (PCC) or primary secondary component carrier (PSCC) as the first CC if there is PCC / PSCC in a band. If there is no PCC / PSCC in the band, the terminal device 120 will select the SCC configured with neighbor cell measurement as the first CC. Otherwise, the terminal device 120 will select one SCC as the first CC based on its implementation. It may provide flexibility for the terminal device 120 to select the CC within a group.
[0052] At 330, the terminal device 120 may transmit, to the network device 120, a measurement report for the group of CCs based on the measurement of the first CC. The measurement report may include the measurement result of the first CC. Accordingly, the network device 110 may receive the measurement report from the terminal device 120. In some embodiments, legacy measurement reporting requirement may still apply to the measurement reporting described above.
[0053] In this way, a measurement report for a group of CCs may be determined with only one CC (or part of the group of CCs) being measured. In other words, only one CC is measured per group, so that optimized CSSF and shorter measurement delay may be achieved. The terminal device 120 may be able to trigger measurement reporting no matter which CC it is performing on the band. This may simplify configuration of the network device 110 while keeping flexibility of selection of measured CC at UE side.
[0054] In some embodiments, the terminal device 120 may evaluate a reporting condition or event for the first CC in the group of CCs. The reporting condition or event may be associated with the group of CCs. The reporting condition or event may be configured by the reporting configuration. The terminal device 120 may transmit, to the network device 110, the measurement report for the group of CCs based on the reporting condition or event is fulfilled on the first CC (based on a result of the measurement of the first CC) . In some embodiments, the terminal device 120 may transmit the measurement report periodically, aperiodically, or semi-persistently. In other words, the measurement report may be event-triggered or transmitted according to pre-configured condition or rule.
[0055] In some embodiments, the measurement report comprises an indication of the first CC, so that the network device 110 may know on which CC a result of the measurement is derived, which may add visibility between the terminal device 120 and the network device 110. The indication of the first CC may comprise a MO index corresponding to the first CC, or an identity of a cell corresponding to the first CC.
[0056] In some embodiments, the measurement report comprises at least the per group measurement identity to indicate to which band or group the measurement report is associated with. This may provide more clear information about measurement behavior of the terminal device 120 to the network device 110.
[0057] In some embodiments, the network device 110 may transmit, to the terminal device 120, an indication of measuring one CC per group. Accordingly, the terminal device 120 may receive the indication from the network device 110. In some embodiments, the terminal device 120 may measure the first CC in the group of CCs based on the indication, and skip the measurement on the other CCs if configured in the group of CCs. In some embodiments, if the terminal device 120 does not receive the indication, the terminal device 120 may perform normal measurement, for example, measuring all CCs if configured. In some other embodiments, the terminal device 120 may measure the first CC in the group of CCs without receiving the indication. In other words, the terminal device 120 may measure the first CC in default and not need any indication. In some embodiments, the network device 110 may transmit the indication before or after transmitting the configuration of measurement and reporting for the group of CCs. In this way, measurement flexibility may be enhanced as a method for the measurement may be determined based on an indication.
[0058] In some embodiments, the terminal device 120 may transmit, to the network device 120, a capability of measuring one CC per group. Accordingly, the network device 110 may receive the capability from the terminal device 120. In some embodiments, the network device 110 may transmit the configuration of measurement and reporting for the group of CCs or the indication of measuring one CC per group based on the capability. For example, the network device 110 may transmit the configuration or the indication based on determining that the terminal device 120 has the capability of measuring one CC per group. In this way, the network device 110 may configure the measurement for the terminal device 120 more accurately, as the network device 110 may know that whether the network device 110 have the capability of measuring one CC per group.
[0059] With the process 300, the network device 110 may configure reporting conditions or events for the whole band without knowing which CC the terminal device 120 is measuring, and the terminal device 120 may leverage the measurement reporting behavior while benefiting from faster measurement.
[0060] Reference is now made to Fig. 4, which shows an example 400 of per FR2 band measurement reporting according to some embodiments of the present disclosure. For the purpose of discussion, the example 400 will be described with reference to Fig. 1. The example 400 may involve the terminal device 120, the network device 110, the PCell 130 and the SCell1 140 as illustrated in Fig. 1.
[0061] The PCell 130 may be operating on CC0 in one band e.g. FR1, SCell1 140 / SCell2 150 / SCell3 160 may be operating on CC1 / CC2 / CC3 respectively on another FR2 band different from the PCell 130.
[0062] At 401, the terminal device 120 may be in connected mode with the PCell 130.
[0063] At 402, the network device 110 may add some SCells (e.g. SCell1 140, SCell2 150, andSCell3 160) into carrier aggregation (CA) operation via a radio resource control (RRC) reconfiguration message. In some embodiments, the network device 110 may also configure legacy measurement for serving CCs and the terminal device 120 may send measurement reporting for each of measurement identity (MeasID) based on the reporting configuration accordingly.
[0064] At 403, the terminal device 120 may indicate it supports measuring one CC per band for optimized CSSF and shorter measurement delay (i.e. the capability of measuring one CC per group in the process 300) .
[0065] There are several options for measurement configuration.
[0066] For option 1, at 404, the network device 110 may configure the measurement by configuring one per-band MO i.e. perbandMO. For example, perbandMO1 = (CC1, CC2, CC3) . The network device 110 may configure a measurement identity i.e. perbandMeasID by linking one per-band MO with one reporting configuration. For example, perbandMeasID1 = (perbandMO1, reportConfigId) . The reporting configuration can include any of the condition or event as in legacy reportConfig in 3GPP technical specification (TS) 38.331 including periodic, aperiodic, semi-persistent and event triggered report configuration. This perbandMO is associated with all the CCs (including serving and neighbor CCs) or all the serving CCs to be measured on the band. These associated CCs may be indicated using cell identity, SSB frequency indication, or ARFCN corresponding to the CC. Alternatively, this perbandMO may be associated with a band index or number. For instance, if the terminal device 120 is configured with n1+n257, the perbandMO may be configured with n257 to indicate this MO is representing all the configured CCs on the band n257.
[0067] For example, the configuration may comprise a list of measurement objects to add and / or modify, each of the measurement objects may comprise a measurement object ID, a measurement object comprising MeasObjectNR (i.e. legacy MO) or perbandMO (i.e. per group MO) that specifies information applicable for measurements on the group of CCs. The perbandMO may comprise a band index or SSB frequency list, SSB subcarrier spacing. The configuration may comprise a measurement ID to add and / or modify, comprising per band measurement ID, per band MO ID (indicated by measurement object ID) , and report configuration ID. The pseudo-code is listed as below:
[0068] For option 2, at 405, the network device 110 may configure legacy MOs for the CCs to be measured by the terminal device 120. For example, MO1 corresponding to CC1, MO2 corresponding to CC2, MO3 corresponding to CC3. This may be captured in the same message at 402. At 406, on top of the legacy configured MOs, the network device 110 may further configure per-band measurement object i.e. perbandMO by associating with all the legacy MOs to be measured on the band. For example, perbandMO1 = MO1, MO2, MO3. The network device 110 may configure a measurement identity i.e. perbandMeasID by linking one per-band MO with one reporting configuration. For example, perbandMeasID1 = (perbandMO1, reportConfigId) . In some embodiments, this step may be combined with step 404 or 402. In some embodiments, the terminal device 120 may trigger legacy measurement reporting in addition to the per-band measurement reporting.
[0069] For example, the configuration may comprise a list of measurement objects to add and / or modify, each of the measurement objects may comprise a measurement object ID, a measurement object comprising MeasObjectNR that specifies information applicable for measurements. The configuration may comprise a perbandMO comprising a per band MO list i.e. a list of MOs on the band. The configuration may comprise a measurement ID to add and / or modify, comprising per band measurement ID, per band MO ID, and report configuration ID. The pseudo-code is listed as below:
[0070] For option 3, at 407, the network device 110 may configure the legacy MOs for the CCs to be measured by the terminal device 120, similar as step 405. At 408, the network device 110 may directly configure the per-band measurement identity i.e. perbandMeasID by linking all the configured legacy MOs on the band with one reporting configuration, instead of configuring per-band MO as 406. For example, perbandMeasID1 = (MO1 / MO2 / MO3, reportConfigId) .
[0071] For example, the configuration may comprise a measurement ID to add and / or modify, comprising per band measurement ID, per band MO list i.e. a list of MOs on the band, and report configuration ID. The pseudo-code is listed as below:
[0072] At 409, the terminal device 120 may receive an indication from the network device 110 to enable the measuring one CC per FR2 band for faster measurement (i.e. the indication of measuring one CC per group in process 300) . This step may apply to any of the options.
[0073] At 410, upon receiving the enabling indication, the terminal device 120 may start to select one CC (e.g. CC1) on the same band based on the perbandMO and / or legacy MOs. At 411 / 412, the terminal device 120 may perform measurement on the single CC (by receiving SSB) e.g. CC1. At 413, the terminal device 120 may evaluate the reporting conditions or events for each of the perbandMeasId based on the measurement on the selected single CC.
[0074] At 414, the terminal device 120 may trigger the measurement reporting for the whole band if the condition is fulfilled on the selected CC irrespective of which CC it is measuring. A perbandMeasID is included to indicate to which band the measurement reporting is associated with. In addition or optionally, the terminal device 120 may further indicate on which MO or CC the measurement result is measured or derived.
[0075] Reference is now made to Fig. 5, which shows an example 500 of per group measurement reporting for FR1 according to some embodiments of the present disclosure. For the purpose of discussion, the example 500 will be described with reference to Fig. 1. The example 500 may involve the terminal device 120, the network device 110, the PCell 130, the SCell1 140 and the SCell3 160 as illustrated in Fig. 1.
[0076] The PCell 130 may be operating on CC0 in one band e.g. FR1, SCell1 140 / SCell2 150 / SCell3 160 may be operating on CC1 / CC2 / CC3 respectively on another FR1 band different from the PCell. The CC1 / CC2 may be contiguous but the CC3 may be non-contiguous.
[0077] At 501, the terminal device 120 may be in connected mode with the PCell 130.
[0078] At 502, the network device 110 may add some SCells (e.g. SCell1 140, SCell2 150, and SCell3 160) into CA operation via an RRC reconfiguration message. In some embodiments, the network device 110 may also configure legacy measurement for serving CCs and the terminal device 120 may send measurement reporting for each of measurement identity (MeasID) based on the reporting configuration accordingly.
[0079] At 503, the terminal device 120 may indicate it supports measuring one CC per contiguous band for FR1 for optimized CSSF and shorter measurement delay (i.e. the capability of measuring one CC per group in the process 300) .
[0080] There are several options for measurement configuration.
[0081] For option 1, at 504, the network device 110 may configure the measurement by configuring one per-group MO i.e. perGroupMO. For example, perGroupMO1 = (CC1, CC2) . The network device 110 may configure a measurement identity i.e. perGroupMeasID by linking one per-group MO with one reporting configuration. For example, pergroupMeasID1 = (perGroupMO1, reportConfigId) . The reporting configuration can include any of the condition or event as in legacy reportConfig in TS 38.331 including periodic, aperiodic, semi-persistent and event triggered report configuration. This perGroupMO is associated with all the CCs (including serving and neighbor CCs) or all serving CCs to be measured on the contiguous band for FR1. These associated CCs may be indicated using cell identity, SSB frequency or ARFCN corresponding to the CC.
[0082] For option 2, at 505, the network device 110 may configure legacy MOs for the CCs to be measured by the terminal device 120. For example, MO1 corresponding to CC1, MO2 corresponding to CC2, MO3 corresponding to CC3. This may be captured in the same message at 502. At 506, on top of the legacy configured MOs, the network device 110 may further configure per-group measurement object i.e. perGroupMO by associating with all the legacy MOs to be measured on the band. For example, perGroupMO1 = (MO1, MO2) . The network device 110 may configure a measurement identity i.e. perGroupMeasID by linking one per-group MO with one reporting configuration. For example, perGroupMeasID1 = (perGroupMO1, reportConfigId) . In some embodiments, this step may be combined with step 504 or 502. In some embodiments, the terminal device 120 may trigger legacy measurement reporting in addition to the per-group measurement reporting.
[0083] For option 3, at 507, the network device 110 may configure the legacy MOs for the CCs to be measured by the terminal device 120, similar as step 505. At 508, the network device 110 may directly configure the per-group measurement identity i.e. perGroupMeasID by linking all the configured legacy MOs on the contiguous band for FR1with one reporting configuration, instead of configuring per-group MO as step 506. For example, perGroupMeasID1 = (MO1 / MO2, reportConfigId) .
[0084] At 509, the terminal device 120 may receive an indication from the network device 110 to enable the measuring one CC per contiguous band for FR1 for faster measurement (i.e. the indication of measuring one CC per group in process 300) . This step may apply to any of the options.
[0085] At 510, upon receiving the enabling indication, the terminal device 120 may start to select one CC for a group based on the pergroupMO and / or legacy MOs. At 511, the terminal device 120 may perform measurement on the CC1 (SSB1) , and may not measure CC2 as they are contiguous carriers in the same band. At 512, the terminal device 120 may perform measurement on the CC3 (SSB3) , since CC3 is non-contiguous. The terminal device 120 may measure the CC3 in legacy way. At 513, the terminal device 120 may evaluate the reporting conditions or events for each of the perGroupMeasId based on the measurement on the selected single CC in the group for the per-group measurement reporting.
[0086] At 514, the terminal device 120 may trigger the measurement reporting if the condition is fulfilled on the selected CC irrespective of which CC it is measuring, which may include both per-group measurement reporting and legacy measurement reporting. The per-group measurement reporting is indicated by pergroupMeasId and legacy measurement reporting is indicated via legacy MeasID. They can be captured in the same or different messages. In addition or optionally, the terminal device 120 may further indicate on which MO or CC the measurement result is derived.
