[0120] The following is an explanation and interpretation of the terminology used in this disclosure.

[0121] I. Introduction to RRM Measurement:

[0122] The quantities measured in RRM measurements may include: reference signal receiving power (RSRP), reference signal receiving quality (RSRQ), signal to interference plus noise ratio (SINR), and reference signal strength indicator (RSSI), etc.

[0123] In some embodiments, the measurement quantity may further include: RSRP, RSRQ, SINR, or RSSI of the channel state information-reference signal (CSI-RS), etc. Alternatively, the measurement quantity may be RSRP, RSRQ, SINR, or RSSI of other reference signals, etc.

[0124] In some embodiments, the measurement may further include: channel status information (CSI), channel quality indicator (CQI), precoding matrix indicator (PMI), precoding type indicator (PTI), diversity indicator (RI), CSI-RS index (CRI), etc.

[0125] In some embodiments, the synchronization signal block (SSB) may also be referred to as the synchronization signal / physical broadcast channel block (SS / PBCH) block. The synchronization signal block may include at least one of the following: PBCH, primary synchronization signal (PSS), and secondary synchronization signal (SSS). The synchronization signal block may also be referred to as SSB, SS / PBCH block, or SS block.

[0126] II. Introduction to SCell:

[0127] Under dual connectivity (DC), a terminal can access two cell groups: the master cell group (MCG) and the secondary cell group (SCG).

[0128] In some embodiments, an MCG may contain multiple cells or cell groups, one of which is used to initiate initial access; this cell may be referred to as the primary cell (PCell). The other cells in the MCG may be referred to as SCells. In an MCG, PCells and SCells within the MCG can be joined together via carrier aggregation (CA). An MCG may include both PCells and SCells.

[0129] In some embodiments, the SCG may include a primary secondary cell (PSCell) and an SCell. Because many signaling messages are only transmitted on the PCell and PSCell, for ease of description, a concept is also defined in the protocol: a special cell (sPCell). The PCell and PSCell are collectively referred to as sPCell.

[0130] III. Introduction to NES Measurement:

[0131] NES is of great significance for environmental sustainability, reducing environmental impact (greenhouse gas emissions), and saving operating costs. As 5G technology becomes more widespread across industries and geographic regions, more advanced services and applications (such as XR) that require very high data rates are being processed, leading to denser networks using more antennas, greater bandwidth, and more frequency bands.

[0132] In Rel-19, to significantly save energy and reduce the impact on terminal service quality, network devices are allowed to enter sleep mode, and are woken up by terminals by sending SSB requests according to their own needs. After being woken up, the network device can send SSBs to the terminal; these SSBs can be called on-demand SSBs (ODSSBs).

[0133] In some embodiments, a network device that supports entering sleep mode can be understood as supporting NES. In this case, one or more cells under the network device can be understood as cells that support NES, and cells that support NES can also be called NES cells.

[0134] In some embodiments, the terminal sends an SSB trigger request to the network device. The network device may respond to the SSB trigger request by sending an SSB trigger signaling to the terminal to indicate the triggered on-demand SSB. The terminal receives the triggered on-demand SSB according to the configuration of the triggered on-demand SSB indicated by the network device.

[0135] In some embodiments, the network device may indicate the triggered on-demand SSB to the terminal via system information block (SIB) 1 or terminal-specific radio resource control (RRC) signaling.

[0136] In some embodiments, network devices may also send SSBs to terminals in a non-broadcasting manner. Such SSBs may be referred to as always-on SSBs, legacy SSBs, normal SSBs, or simply SSBs.

[0137] In some embodiments, for NES-enabled SCells (NES SCells), the network device always broadcasts an always-on SSB on the SCell. However, the network device does not send an on-demand SSB on the SCell before sending the SSB trigger signaling; it only sends an on-demand SSB after sending the SSB trigger signaling. Therefore, on the SCell, the network device broadcasts both always-on and on-demand SSBs to the terminal. In this case, the terminal can receive either the always-on SSB or the on-demand SSB.

[0138] In some embodiments, the SSB triggering signaling described above can be downlink signaling. In one example, downlink signaling may include radio resource control (RRC) signaling, media access control (MAC) control element (CE), downlink control information (DCI), physical downlink control channel (PDCCH) signaling, physical downlink share channel (PDSCH) signaling, etc.

[0139] It should be noted that the above "simultaneously" can be understood as: within a certain period of time after the network device sends the SSB trigger signaling, it sends both always-on SSB and on-demand SSB to the terminal, and the time domain positions of always-on SSB and on-demand SSB are different.

[0140] In one example, Figure 1B is a schematic diagram of SSB transmission according to an embodiment of the present disclosure. As shown in Figure 1B, at time t0, the network device configures the SCell for the terminal. The SCell configuration may include always-on SSB configuration and on-demand SSB configuration. At time n after time t0, the network device sends an OD SSB triggering signaling to the terminal according to the terminal's needs to indicate the triggered on-demand SSB. Then, after time n, the network device sends always-on SSB and on-demand SSB to the terminal. At time t1, the network device indicates SCell activation to the terminal.

[0141] In some embodiments, always-on SSB can be sent periodically. The period of always-on SSB can be determined according to predefined information (such as protocol specifications) or it can be configured by the network device for SCell.

[0142] In some embodiments, on-demand SSBs can be sent periodically. The period of on-demand SSBs can be determined according to predefined information (such as protocol specifications) or configured by the network device for the SCell.

[0143] Therefore, for NES SCell, the terminal can receive both always-on SSB and on-demand SSB. So, how to achieve measurement of NES SCell cells is an urgent problem to be solved.

[0144] Figure 2A is an interactive schematic diagram of a communication method provided according to an embodiment of the present disclosure. The communication method involved in this embodiment can be applied to a communication system 100. As shown in Figure 2A, the communication method of this embodiment includes steps S2101 to S2106.

[0145] In step S2101, the terminal sends the first information.

[0146] In some embodiments, the network device receives first information.

[0147] In some embodiments, the first information is used to indicate the terminal's ability to support on-demand SSB.

[0148] In some embodiments, the name of the first information is not specifically limited; for example, it can be capability information, auxiliary information, instruction information, etc.

[0149] In some embodiments, the first information may be carried in uplink signaling. In one example, the uplink signaling may include radio resource control (RRC) signaling, media access control (MAC) control element (CE), uplink control information (UCI), physical uplink control channel (PUCCH) signaling, physical uplink share channel (PUSCH) signaling, etc.

[0150] In some embodiments, the terminal's ability to send SSB support messages to the network device according to the terminal's needs may include: supporting on-demand SSB or not supporting on-demand SSB. In one embodiment, supporting on-demand SSB can also be understood as supporting NES, supporting on-demand SSB transmission, supporting on-demand SSB-based measurements, etc. In one embodiment, not supporting on-demand SSB can be understood as not supporting NES, not supporting on-demand SSB transmission, not supporting on-demand SSB-based measurements, etc.

[0151] In some embodiments, the terminal's support for always-on SSB can be set to support by default. In this case, when the terminal reports its capabilities, it can only report the first piece of information to indicate its support for on-demand SSB.

[0152] In some embodiments, the terminal may also report its support for always-on SSB to the network device. In this case, the terminal may also send third information to the network device to indicate its support for always-on SSB. In one embodiment, the first information and the third information may be carried in different information fields of the same signaling or in different signaling.

[0153] In some embodiments, the terminal's support for network device broadcast SSB may include: supporting always-on SSB or not supporting always-on SSB. In one embodiment, supporting always-on SSB can also be understood as supporting always-on SSB transmission, supporting always-on SSB-based measurements, etc. In one embodiment, not supporting on-demand SSB can be understood as not supporting always-on SSB transmission, not supporting always-on SSB-based measurements, etc.

[0154] In some embodiments, the name of the third information is not specifically limited; for example, it can be capability information, auxiliary information, instruction information, etc.

[0155] In some embodiments, when a terminal supports both always-on SSB and on-demand SSB, the network device can configure both always-on SSB and on-demand SSB on the SCell. In this case, after on-demand SSB is triggered, the terminal can receive both always-on SSB and on-demand SSB. In other embodiments, when a terminal supports always-on SSB but not on-demand SSB, the network device can configure only always-on SSB on the SCell. In this case, the terminal can only receive always-on SSB on the SCell and cannot receive on-demand SSB.

[0156] In some embodiments, a terminal can indicate to a network device whether it supports on-demand SSB by using different values ​​of the first information. In one embodiment, a first value of the first information can indicate that the terminal supports on-demand SSB. In another embodiment, a second value of the first information can indicate that the terminal does not support on-demand SSB.

[0157] In some embodiments, the first information indicates that the terminal supports on-demand SSB. Therefore, the terminal can indicate to the network device whether it supports on-demand SSB by whether or not it sends the first information. In one embodiment, if the terminal sends the first information, it can indicate that the terminal supports on-demand SSB. In another embodiment, if the terminal does not send the first information, it can indicate that the terminal does not support on-demand SSB. In this case, step S2101 can be omitted.

[0158] In some embodiments, the terminal's support for performing measurements on the SCell may be either a default configuration or indicated by predefined information (such as as specified in the protocol). In this case, step S2101 may be omitted, but the network device and the terminal need to reach a consistent understanding of the terminal's capabilities.

[0159] It should be noted that the terms "support on-demand SSB", "support on-demand SSB transport", and "support NES" are interchangeable.

[0160] In step S2102, the network device sends the fourth information.

[0161] In some embodiments, the terminal receives fourth information.

[0162] In some embodiments, the fourth information is used to indicate the always-on SSB configuration of SCell.

[0163] In some embodiments, the name of the fourth information is not specifically limited. For example, it can be configuration information, SCell configuration information, always-on SSB configuration information, etc.

[0164] In some embodiments, the fourth information may indicate parameters of the always-on SSB, such as the always-on SSB period, the time-domain location of the always-on SSB, the frequency-domain location of the always-on SSB, etc.

[0165] In some embodiments, when the terminal sends a third message indicating support for always-on SSB, the network device may send a fourth message to the terminal to indicate the always-on SSB configuration of the SCell.

[0166] In some embodiments, if the terminal supports always-on SSB by default, the network device may also send a fourth message to indicate the always-on SSB configuration on the SCell.

[0167] In step S2103, the network device sends the second information.

[0168] In some embodiments, the terminal receives the second information. In one embodiment, the second information and the fourth information may be carried in different information fields of the same signaling or in different signaling.

[0169] In some embodiments, the second information is used to indicate the configuration of the on-demand SSB of the SCell.

[0170] In some embodiments, the name of the second information is not specifically limited. For example, it can be configuration information, SCell configuration information, SSB configuration information, etc.

[0171] In some embodiments, the second information may indicate parameters of the on-demand SSB, such as the period of the on-demand SSB, the time-domain position of the on-demand SSB, the frequency-domain position of the on-demand SSB, etc.

[0172] In some embodiments, the on-demand SSB configuration indicated by the second information may be cell-related, in which case all terminals within that cell can obtain the on-demand SSB configuration. In some embodiments, the on-demand SSB configuration indicated by the second information may be UE-specific, in which case a terminal or UE group can obtain the on-demand SSB configuration.

[0173] In some embodiments, when the first information indicates that the terminal supports on-demand SSB, the network device sends a second information.

[0174] In some embodiments, if the first information indicates that the terminal does not support on-demand SSB, the network device does not send the second information. In this case, steps S2103, S2105 to S2106 are omitted.

[0175] In step S2104, the network device broadcasts the first SSB on the SCell.

[0176] In some embodiments, the first SSB is the always-on SSB of the SCell.

[0177] In some embodiments, the terminal may receive always-on SSB, i.e., the first SSB, on the SCell.

[0178] In some embodiments, the terminal may receive an always-on SSB, i.e., a first SSB, on the SCell according to the always-on SSB configuration indicated by the fourth information.

[0179] In some embodiments, step S2104 is executed after step S2102, and can be executed simultaneously with step S2103 or sequentially.

[0180] In step S2105, the network device sends a second SSB on the SCell according to the terminal's requirements.

[0181] In some embodiments, the second SSB is the on-demand SSB of the SCell. In some embodiments, the second SSB is the triggered on-demand SSB of the SCell.

[0182] In some embodiments, the terminal may receive a triggered on-demand SSB, i.e., a second SSB, on the SCell.

[0183] In some embodiments, there may be multiple second SSBs, which belong to the same SSB set.

[0184] In some embodiments, the terminal sends an SSB trigger request to the network device. The network device responds to the SSB trigger request by sending an SSB trigger signaling message to the terminal, indicating the triggered on-demand SSB. Subsequently, the network device sends the triggered on-demand SSB, i.e., the second SSB, on the SCell. Simultaneously, the terminal receives the triggered on-demand SSB, i.e., the second SSB, in the SCell according to the configuration of the on-demand SSB indicated by the second information.

[0185] In some embodiments, the always-on SSB and the on-demand SSB may not overlap in the time domain. Therefore, the first SSB and the second SSB also do not overlap in the time domain.

[0186] In some embodiments, the SSB triggering signaling can be unicast. In one example, terminal A sends an SSB trigger request to the network device, and the network device sends SSB triggering signaling to terminal A. In some embodiments, the SSB triggering signaling can also be multicast. In one example, terminal A sends an SSB trigger request to the network device, and the network device sends SSB triggering signaling to the terminal group to which terminal A belongs, to indicate the triggered on-demand SSB to the terminals in that group.

[0187] In one embodiment, the period of the on-demand SSB can be the same as or different from the period of the always-on SSB. In one example, the period of the on-demand SSB is shorter than the period of the always-on SSB. In this case, the period of the second SSB is shorter than the period of the first SSB. In another example, the period of the on-demand SSB is longer than the period of the always-on SSB. In this case, the period of the second SSB is longer than the period of the first SSB.

[0188] In some embodiments, steps S2102 and S2104, along with steps S2103 and S2105, may be executed simultaneously or sequentially.

[0189] In step S2106, the terminal performs a measurement on the SCell based on the first SSB or the second SSB, according to the terminal implementation.

[0190] In some embodiments, the terminal determines whether to perform a measurement on the SCell based on a first SSB or a second SSB. In some embodiments, the terminal selects to perform the measurement on the SCell based on either the first or second SSB. In some embodiments, the terminal selects to perform the measurement on the SCell based on the first SSB. In some embodiments, the terminal selects to perform the measurement on the SCell based on the second SSB.

[0191] In some embodiments, the terminal performs measurements on the SCell based on a selected SSB. In one embodiment, the terminal performs measurements on the SCell based on a selected first SSB. In another embodiment, the terminal performs measurements on the SCell based on a selected second SSB.

[0192] In some embodiments, the terms "determine" and "select" may be used interchangeably.

[0193] In some embodiments, the terminal may, according to its implementation, select to perform measurements on the SCell based on either a first SSB or a second SSB. In some embodiments, the terminal may autonomously select to perform measurements on the SCell based on either a first SSB or a second SSB, based on factors such as latency and power consumption, so that the terminal can complete the measurement as quickly as possible and reduce power consumption.

[0194] In one embodiment, the terminal can select to perform measurements on the SCell based on either the first or second SSB, depending on the period of the second SSB. In one example, the period of the second SSB is shorter than the period of the first SSB; in this case, the terminal can choose to perform measurements on the SCell based on the second SSB. In another example, the period of the second SSB is longer than the period of the first SSB; in this case, the terminal can choose to perform measurements on the SCell based on the first SSB. Thus, by selecting the SSB with the relatively shorter period for measurement, the terminal can complete the measurement as quickly as possible, reducing power consumption.

[0195] In one embodiment, the terminal can select to perform a measurement on the SCell based on either the first SSB or the second SSB, depending on the time-domain location of the second SSB. In one example, after the second SSB is triggered, the terminal first receives the second SSB; in this case, the terminal can choose to perform a measurement on the SCell based on the second SSB. In another example, after the second SSB is triggered, the terminal first receives the first SSB; in this case, the terminal can choose to perform a measurement on the SCell based on the first SSB.

[0196] It should be noted that the above is only an example of the terminal determining whether to perform a measurement on the SCell based on the first SSB or the second SSB. The terminal may also refer to other factors, such as cell signal quality and the terminal's mobile location. This disclosure does not specifically limit these factors.

[0197] In some embodiments, the measurements performed by the terminal on the SCell can be used for processes such as SCell time / frequency synchronization, layer 1 (L1) / layer 3 (L3) measurements, and SCell activation.

[0198] In some embodiments, since the terminal performs measurements on the SCell based on both a first SSB and a second SSB, the terminal can determine the measurement period on the SCell based on the periods of the first and second SSBs. In one example, to provide more lenient measurement requirements, the terminal can determine the measurement period on the SCell based on the maximum value of the periods of the first and second SSBs. In one example, the terminal's measurement period can be as shown in Tables 1 and 2 below, where Table 1 shows the measurement period for measurements within the gapless frequency range of FR1, and Table 2 shows the measurement period for measurements within the gapless frequency range of FR2.

[0199] In some embodiments, in Tables 1 and 2, DRX cycle (discontinuous reception cycle) is the discontinuous reception cycle, TSSB_measurement_period_intra is the terminal's co-frequency cell measurement cycle, measCycleSCell is the always-on SSB cycle, ODSSBCycle is the network-configured on-demand SSB cycle, and CSSF... intra (Carrier Specific Scaling Factor) The carrier-specific scaling factor for the same frequency, K pM is the scaling factor in the absence of measurement gaps. meas_period_w / o_gaps This is a constant determined based on the power type.

[0202] It should be noted that the requirements expressed in Tables 1 and 2 above can be applied to inactive SCells, as well as SCells in inactive SCGs.

[0203] This completes the terminal's measurement of the NES SCell.

[0205] In some embodiments, step S2101 is optional, and one or more of these steps may be omitted or substituted in different embodiments.

[0206] Figure 2B is another interactive schematic diagram of the communication method provided according to an embodiment of the present disclosure. The communication method involved in the embodiment of the present disclosure can be applied to the communication system 100. As shown in Figure 2B, the communication method of the embodiment of the present disclosure includes steps S2201 to S2206.

[0207] In step S2201, the terminal sends the first information.

[0208] Optional implementations of step S2201 can also be found in optional implementations of step S2101 in Figure 2A, as well as other related parts in the embodiments involved in Figure 2A, which will not be repeated here.

[0217] In step S2206, the terminal performs a measurement on the SCell based on the second SSB according to predefined information.

[0218] In some embodiments, the terminal determines, according to predefined information (such as a protocol), to perform a measurement on the SCell based on a second SSB. In this case, the second SSB is a triggered on-demand SSB. In some embodiments, the terminal, according to a protocol, forces the selection to perform the measurement on the SCell based on an on-demand SSB.

[0219] In some embodiments, after an on-demand SSB is triggered, the terminal can perform measurements on the SCell based on the triggered on-demand SSB (i.e., the second SSB). In some embodiments, after an on-demand SSB is triggered, the terminal can force the selection to perform measurements on the SCell based on the second SSB.

[0220] In some embodiments, the measurements performed by the terminal on the SCell are used for processes such as SCell time / frequency synchronization, L1 / L3 measurements, and SCell activation.

[0221] In some embodiments, since the terminal selects to perform measurements on the SCell based on the second SSB, the terminal can determine the measurement period on the SCell according to the period of the second SSB. In one example, the measurement period of the terminal can be shown in Tables 3 and 4 below, where Table 3 is the measurement period for measurements within the gapless frequency range of FR1, and Table 4 is the measurement period for measurements within the gapless frequency range of FR2.

[0224] It should be noted that the requirements expressed in Tables 3 and 4 above can be applied to inactive SCells, as well as SCells in inactive SCGs.

[0225] In some embodiments, the terminal performs measurements on the SCell based on the second SSB according to predefined information. In this case, after step S2202, the terminal may not detect the first SSB, and step S2204 may be omitted.

[0226] This completes the terminal's measurement of the NES SCell.

[0279] In the following, the technical solutions of the embodiments of this disclosure will be described by way of specific implementation.

[0280] In some embodiments, the following scenarios can be considered in Rel-19 NES technology:

[0281] For NES ODSSB (such as the second SSB):

[0282] Scenario 1: The NES ODSSB is triggered before the SCell is configured to the UE and the UE receives the SCell activation command.

[0283] Scenario 2: After the UE receives the SCell activation command, the NES ODSSB is triggered.

[0284] In some embodiments, the SSB exists in the following ways:

[0285] Scenario 1: No always-on SSB (such as the first SSB) is transmitted in the cell.

[0286] Scenario 2: Always-on SSB transmits periodically within the cell.

[0287] In some embodiments, in scenario one, for case two, the basic process of gNB sending always-on SSB and OD SSB to UE is shown in Figure 1B above.

[0288] In some embodiments, the UE may receive both always-on SSB and OD SSB together.

[0289] In some embodiments, for a UE that supports Rel-19 NES, the UE may perform measurements based solely on always-on SSB, including measurements for SCell time-frequency synchronization, L1 / L3 measurements, and SCell activation.

[0290] In some embodiments, for UEs that support Rel-19 NES, the following solutions may exist:

[0291] Option 1: The UE decides independently whether to perform measurements based on always-on SSB or OD SSB.

[0292] Option 2: The UE needs to perform measurements based on the OD SSB when the OD SSB is triggered.

[0293] In some embodiments, the UE autonomously selects the SSB. In one embodiment, if the UE executes according to Scheme 1, the time-frequency synchronization of the SCell, L1 / L3 measurement, and SCell activation measurement requirements can be as shown in Tables 1 and 2.

[0294] In some embodiments, the UE makes measuring OD SSB a mandatory option.

[0295] In one embodiment, if the UE performs according to Scheme 2, the time-frequency synchronization of SCell, L1 / L3 measurement, and SCell activation measurement requirements can be as shown in Tables 3 and 4.
