Description

Measurement methods and devices Technical Field

[0001] The embodiments of this application relate to the field of communication technology. Background Technology

[0002] As a crucial component of global new infrastructure construction, 5G communication networks have experienced rapid development worldwide in recent years. With the increasing scale of these networks, operators' energy consumption continues to rise. For example, data released by China's Ministry of Industry and Information Technology shows that energy consumption in 2022 will increase by approximately 80% compared to 2015.

[0003] With the deployment of 5G networks and the large-scale commercialization of 5G Active Antenna Units (AAUs), the energy consumption of AAUs will increase exponentially compared to the Remote Radio Units (RRUs) primarily used in 3G and 4G, due to their higher power consumption. 5G defines three major service types: Enhanced Mobile Broadband (eMBB), Massive Machine Type Communication (mMTC), and Ultra Reliable Low Latency Communication (URLLC). This leads to a continuous increase in bursty small-packet traffic in 5G, requiring base stations to operate 24 / 7. Consequently, the average daily energy consumption of 5G sites will be more than double that of 4G.

[0004] In the 5G era, 3GPP introduced key technologies such as Massive MIMO and larger radio frequency bandwidth. 5G supports higher data rates and larger data volumes, requiring more transmission bandwidth, and high-frequency band deployment will be the main frequency band for future 5G expansion. However, the transmission characteristics of high-frequency bands limit the coverage of 5G sites, leading to a denser deployment of 5G sites. Furthermore, the increased energy consumption from additional sites will place significant operational cost pressures on operators. Therefore, network energy saving is crucial for reducing operating costs, making it one of the most pressing issues to be addressed in the 5G and even 6G era.

[0005] To achieve energy savings, network devices can implement energy-saving measures in the time, frequency, spatial, and / or energy domains based on network load. For example, in the spatial and energy domains, network devices can shut down some antennas when the load is low to save energy. In the time domain, network devices can adjust the period or time position of the cell common reference signal (e.g., SSB / SIB) when there are few users and the load is low to achieve energy savings.

[0006] It should be noted that the above introduction to the technical background is only for the purpose of providing a clear and complete explanation of the technical solutions of this application and facilitating understanding by those skilled in the art. It should not be assumed that these technical solutions are known to those skilled in the art simply because they have been described in the background section of this application.

[0007] Summary of the Invention

[0008] The inventors discovered that, in the time domain, for a serving cell that functions solely as a secondary cell, when there is no load and no data transmission is required on the serving cell, network devices can disable / stop the transmission of the serving cell's common reference signal (e.g., SSB) to achieve energy savings. When the serving cell is loaded and data transmission is required, the network device activates / triggers the serving cell's common reference signal via signaling for L1 / L3 measurements of terminal devices, rapid activation of secondary cells, and other operations. This energy-saving method of turning common reference signal transmission on or off based on changes in traffic volume ensures normal communication for terminal devices while also achieving energy savings for network devices. How to perform on-demand SSB measurements has become a pressing issue for network energy-saving technologies.

As shown in Figure 1, the communication system 100 may include a network device 101 and terminal devices 102 and 103. For simplicity, Figure 1 only illustrates the case of two terminal devices and one network device, but the embodiments of this application are not limited to this.

[0054] In this embodiment of the application, network device 101 and terminal devices 102 and 103 can transmit existing services or services that can be implemented in the future. For example, these services may include, but are not limited to: enhanced mobile broadband (eMBB), massive machine-type communication (mMTC), and ultra-reliable and low-latency communication (URLLC), etc.

[0056] System message design is a crucial concept in wireless communication systems. Cell-level system messages primarily serve to configure cell camping, provide user access, and facilitate interoperability. 5G NR has simplified system messages to some extent, and its design differs from 4G in terms of synchronization signals and system message design, thus necessitating a re-evaluation.

[0057] Unlike 4G, which separates the cell downlink synchronization signal and the physical broadcast channel, 5G couples the cell synchronization signal (SS) and the physical broadcast channel (PBCH) to some extent, presenting them as SS / PBCH resource blocks, or simply synchronization signal blocks (SSBs).

[0058] Figure 2 is a schematic diagram of the time-frequency structure of SSB. As shown in Figure 2, in 5G NR, SSB occupies 20 consecutive physical resource blocks (PRBs) in the frequency domain, with a maximum of 240 consecutive resource elements (REs). Among them, the synchronization signals (including the primary synchronization signal PSS and the secondary synchronization signal SSS) occupy 127 consecutive REs in the first and third OFDM symbols of SSB, respectively. The frequency domain center position of SSB can be flexibly configured and adjusted according to local conditions.

[0059] After the UE achieves SSB synchronization through frequency search, it decodes the Master Information Block (MIB) in the Physical Broadcast Channel. In LTE systems, in addition to configuring the MIB, the cell also configures SIB1 according to a fixed transmission period, and transmits the necessary parameter configurations for resolving SIB2 to SIBN through SIB1. 5G NR provides an optimized system message configuration mechanism, namely, on-demand configuration; SIB1 is not necessarily configured according to a fixed period in principle. However, SIB1 transmits important information related to cell selection, and even if not configured according to a fixed period, it still needs to be configured semi-statically through RRC signaling. Since the PDCCH carries limited content, and cell-level system messages generally do not change dynamically, PDCCH is generally not used to carry system messages in the design. In 5G NR, configuration is achieved semi-statically through RRC messages.

[0060] The "on-demand" design concept of 5G NR system messages greatly reduces the resource consumption overhead of system messages, while terminal devices can also reduce the power consumption caused by periodically listening to system messages to a certain extent. In 5G NR, the parameter `ssb-SubcarrierOffset` in the MIB determines whether SIB1 is configured in the PDCCH common search space `CORESET#0`. This parameter represents the subcarrier offset of the SSB's frequency domain start position relative to the common PRB. For 5G cell carriers in the FR1 (sub 6GHz) band, the UE, in conjunction with the PBCH, uses an additional 1 bit representing the time domain payload to jointly determine the SSB's subcarrier offset relative to the common PRB, with a value ranging from 0 to 31. If this value is not greater than 23, the UE considers the cell to have configured system message SIB1; otherwise, the SIB1 content does not appear as a system message. For 5G cell carriers in the FR2 band, the UE only uses the parameter `ssb-SubcarrierOffset` to determine the subcarrier offset, with a value ranging from 0 to 15. If this value is not greater than 11, the UE considers the cell to have configured system message SIB1; otherwise, the SIB1 content does not appear as a system message. If this parameter is not configured, the UE determines the SSB's frequency domain subcarrier offset through frequency search.

[0061] 5G NR introduces the concept of shaped narrow beams. The beam pattern is not explicitly defined; within a single SSB transmission cycle, the shaped narrow beams transmitted by the SSB at different candidate transmission times are not identical. The protocol specifies that a maximum of one SSB transmission occurs every 80ms, meaning that the higher-layer content carried by the SSB will not change for at least an 80ms higher-layer scheduling period. The physical layer transmission cycle of the SSB can be configured via the higher-layer parameter `ssb-periodicityServingCell`, with values ​​ranging from {5ms, 10ms, 20ms, 40ms, 80ms, 160ms}. Setting the SSB repetition cycle is primarily for SSB transmission rate matching considerations. A larger cycle means less time-domain resources are occupied by the SSB, potentially lengthening the UE's listening period. If this parameter is not configured, the UE defaults to a 5ms SSB transmission cycle. The protocol stipulates that during initial cell selection, the UE can assume a 20ms cycle to search for half-frames containing SSBs, providing a theoretical basis for optimizing the downlink synchronous network search mechanism.

[0062] For different subcarrier spacings, the candidate positions of the SSB in each half-frame transmission are defined as follows:

[0063] A: With a subcarrier spacing of 15kHz, for NR carrier frequencies within the FR1 band not exceeding 3GHz, the candidate transmission times for the SSB can be configured at the {2, 8} OFDM positions in time slots 0 and 1, resulting in a total of 4 candidate times; while for NR carrier frequencies within the FR1 band exceeding 3GHz, the candidate transmission times for the SSB can be configured at the {2, 8} OFDM positions in time slots 0, 1, 2, and 3, resulting in a total of 8 candidate times.

[0064] B: With a subcarrier spacing of 30kHz, for NR carrier frequencies within the FR1 band not exceeding 3GHz, the candidate transmission times for the SSB can be configured at the {4, 8, 16, 20} OFDM positions calculated starting from slot 0, resulting in a total of 4 candidate times; while for NR carrier frequencies within the FR1 band exceeding 3GHz, the candidate transmission times for the SSB are configured at the {4, 8, 16, 20} OFDM positions calculated starting from slots 0 and 2, resulting in a total of 8 candidate times.

[0065] C: With a subcarrier spacing of 30kHz, in 5G FDD spectrum mode, for NR carrier frequencies within the FR1 band not exceeding 3GHz, the candidate transmission time of the SSB can be configured at the {2, 8} OFDM position in time slots 0 and 1, resulting in a total of 4 candidate times; while for NR carrier frequencies within the FR1 band exceeding 3GHz, the candidate transmission time of the SSB is configured at the {2, 8} OFDM position in time slots 0, 1, 2, and 3, resulting in a total of 8 candidate times. In 5G TDD spectrum mode, for NR carrier frequencies within the FR1 band not exceeding 2.4GHz, the candidate transmission time of the SSB can be configured at the {2, 8} OFDM position in time slots 0 and 1, resulting in a total of 4 candidate times; while for NR carrier frequencies within the FR1 band exceeding 2.4GHz, the candidate transmission time of the SSB is configured at the {2, 8} OFDM position in time slots 0, 1, 2, and 3, resulting in a total of 8 candidate times.

[0066] D: The subcarrier spacing is 120kHz. For the NR carrier frequency within the FR2 band, the candidate transmission times of the SSB are configured in slots 0, 2, 4, 6, 10, 12, 14, 16, 20, 22, 24, 26, 30, 32, 34, and 36, which are the initial calculation OFDM positions {4, 8, 16, 20}, for a total of 64 candidate times.

[0067] E: Subcarrier spacing 240kHz. For NR carrier frequencies within the FR band, the candidate transmission times of SSB are configured in time slots 0, 4, 8, 12, 20, 24, 28, and 32, which are the initial calculated OFDM positions {8, 12, 16, 20, 32, 36, 40, 44}, for a total of 64 candidate times.

[0068] For the SSB candidate location pattern ABCDE transmitted within a half-frame, the UE can determine the specific index position of the currently transmitted SSB by decoding the PBCH payload bits. For a half-frame containing 4 SSB candidate transmission positions, the index is determined using 2 least significant bits (LSB). For a half-frame containing 8 SSB candidate transmission positions, the index is determined using 3 least significant bits (LSB). In both cases, the PBCH index corresponds one-to-one with the initial sequence index of the pseudo-random sequence of the DMRS in the SSB. When determining 2 or 3 least significant bits, the UE does not directly obtain this information by decoding the PBCH transmission bits, but rather indirectly performs a logical mapping by decoding the DMRS. A half-frame contains 64 SSB candidate transmission positions. The DMRS index in the transmitted SSB is mapped cyclically using 3 least significant bits (8 SSB cycles). The UE combines the 3 least significant bits (LSB) with the 3 additional most significant bits (MSB) of the PBCH payload to jointly determine the transmission index of the SSB. The PBCH payload consists of 32 bits, including 23 bits carrying RRC content. Of these 23 bits, 6 bits are used as the high-order 6 bits for calculating the radio frame. In addition to these 23 bits, the physical layer adds 4 bits related to the transmission time as the low-order 4 bits for calculating the radio frame, 1 bit as the half-frame identifier in the radio frame, 3 bits as the high-order 3 bits for determining the SSB index, and the remaining 1 bit is not specified by the protocol. The MAC layer entity fills it in to align with the transmitted bytes.

[0069] Figure 3 is a schematic diagram of SSB candidates. As shown in Figure 3, different frequencies and subcarrier spacings can correspond to different numbers of SSB candidates. For example, when the frequency band is less than or equal to 3 GHz and the subcarrier spacing is 15 kHz, the number of SSB candidates is 4.

[0070] The SSB diagram shows the possible candidate locations of SSBs and the maximum value L of SSBs within the SSB burst set. max The actual number of activated SSBs can be less than L. max The base station notifies the UE which SSBs are activated and used via SIB1 or the higher-layer parameter ssb-PositionInBurst in UE-specific RRC signaling. For SSB-related RRC parameters, please refer to relevant technical documentation.

[0082] The above description illustrates the SSB-related content of the embodiments of this application. This application is not limited thereto, and related technologies can be referenced. Furthermore, the above content, as part of the embodiments of this application, can be combined with the following embodiments.

[0083] Network devices can configure SSBs for secondary cells, and terminal devices perform measurement and synchronization operations based on the SSBs configured at fixed periods. Alternatively, network devices can choose not to configure an SSB on the secondary cell, but instead configure a reference cell. Terminal devices can then perform measurement and synchronization based on the reference cell's SSB. By default, the reference cell and the current secondary cell are synchronized and co-located. Terminal devices can perform time-frequency synchronization operations for the current secondary cell based on the reference cell's SSB. This supports SSB-based QCL reference, SSB-based CSI measurement and reporting, and SSB-based RLM and BFD / BFR.

[0084] In network energy-saving technologies, network devices aim to disable the Service Shield Bus (SSB) when there is no load and trigger / activate it when there is a load on secondary cells. This type of SSB, which transmits only when needed and does not transmit when not needed, is a new type of SSB that does not exist in existing protocols. If Rel-19 NES introduces on-demand SSB (OD-SSB), this new type of on-demand SSB needs to support QCL reference, CSI measurement, RLM, and BFD / BFR based on on-demand SSB.

[0085] In the embodiments of this application, higher-layer signaling may be, for example, Radio Resource Control (RRC) signaling; for example, referred to as an RRC message, including MIB, system information, dedicated RRC messages; or referred to as an RRC information element. Higher-layer signaling may also be, for example, Medium Access Control (MAC) signaling; or referred to as a MAC control element. However, this application is not limited to these.

[0086] In the following description, without causing confusion, the terms "PDCCH" and "Physical Downlink Control Channel" or "Downlink Control Information" are interchangeable, and the terms "PDSCH" and "Physical Downlink Data Channel" or "Downlink Data" are also interchangeable. Furthermore, transmitting or receiving a PDCCH can be understood as transmitting or receiving downlink control information carried by the PDCCH; transmitting or receiving a PDSCH can be understood as transmitting or receiving downlink data carried by the PDSCH. In the embodiments of this application, the terms "indicator," "activate," and "trigger" are interchangeable, or can be used in combination; for example, "indicator / trigger" can be replaced by "activate / deactivate" or "enable / deactivate," etc.

[0087] First aspect of the embodiments

[0088] This application provides a measurement method, described from the perspective of a terminal device. Figure 4 is a schematic diagram of a measurement method according to an embodiment of this application. As shown in Figure 4, the method includes:

[0091] 403, The terminal device performs measurements based on at least one first SSB configuration and / or one second SSB configuration.

[0092] It is worth noting that Figure 4 above is only an illustrative description of the embodiments of this application, but this application is not limited thereto. For example, the execution order between various operations can be appropriately adjusted, and other operations can be added or some operations can be removed. Those skilled in the art can make appropriate modifications based on the above content, and are not limited to the description in Figure 4 above.

[0093] In this embodiment, the network device can configure one or more secondary cells (Scells) for the terminal device via RRC, and can configure SSBs (e.g., always-on SSB / CD-SSB or on-demand SSB) for one or more secondary cells (Scells). The on-demand SSB of the configured secondary cell is indicated / triggered via MAC CE, RRC signaling, or DCI signaling, and / or the trigger offset of the on-demand SSB is indicated. In this embodiment, the terms "indicate," "trigger," "activate," "deactivate," "enable," "deactivate," "activate / deactivate," and "enable / deactivate" are interchangeable.

[0094] In some embodiments, the first SSB is configured as a periodic always-on SSB or a cell-defined SSB (CD-SSB); the second SSB is configured as a semi-persistent SSB or an on-demand SSB; and the indication information is carried in RRC signaling and / or MAC CE and / or DCI.

[0095] In some embodiments, the terminal device is a UE that supports network power saving (e.g., referred to as a Rel-19 NES capable UE), but this application is not limited thereto. The measurements include at least one of the following: Radio Link Monitoring (RLM) or Radio Link Management (RLM), Beam Link Monitoring (BLM) or Beam Link Management (BLM), CSI measurement and / or reporting, Beam Failure Detection (BFD) / Beam Failure Recovery (BFR), and Quasi-Co-location (QCL) reference. Specific details regarding the measurements can be found in the foregoing embodiments or related technologies.

[0096] The following section will first use an always-on SSB and an on-demand SSB as examples to illustrate the scenarios supported by the serving cell that supports on-demand SSB secondary cell operation.

[0097] In some embodiments, an on-demand SSB is an SSB triggered by a network device on a secondary cell for Layer 1 / Layer 3 (L1 / L3) measurements; the secondary cell does not transmit an SSB before triggering the on-demand SSB, or the secondary cell transmits an always-on SSB (e.g., CD-SSB of an existing protocol); the network device indicates / triggers the on-demand SSB when sending a secondary cell activation command (a secondary cell activation command based on RRC or MAC CE), or indicates / triggers the on-demand SSB while the secondary cell is configured but not activated.

[0098] Figure 5 is an example diagram of on-demand SSB triggering according to an embodiment of this application, showing an example where there is no always-on SSB, and the cell indicates / triggers on-demand SSB as needed. As shown in Figure 5, the network device indicates / triggers on-demand SSB when sending the secondary cell activation command, or it can indicate / trigger on-demand SSB during the period when the secondary cell is configured but not yet activated.

[0099] Figure 6 is another example diagram of on-demand SSB triggering according to an embodiment of this application, showing an example of always-on SSB. As shown in Figure 6, on-demand SSB can be indicated / triggered at the time of sending the secondary cell activation command, or it can be indicated / triggered during the period when the secondary cell is configured but not yet activated; always-on SSB exists before or after the on-demand SSB is triggered.

[0100] In some embodiments, the terminal device supports indication / triggering of on-demand SSB based on RRC and / or MAC CE, or the terminal device supports activation / deactivation, enable / disable of on-demand SSB based on RRC and / or MAC CE.

[0101] For example, the activation / deactivation of the on-demand SSB is independent of the activation / deactivation of the SCell. One MAC CE can be used to activate / deactivate the on-demand SSB, and another MAC CE can be used to activate / deactivate the SCell; this application is not limited to this.

[0102] In some embodiments, the terminal device supports simultaneous activation / deactivation of on-demand SSB and secondary cell (SCell) based on the same RRC and / or MAC CE, or the terminal device supports simultaneous enable / de-enable of on-demand SSB and secondary cell (SCell) based on the same RRC and / or MAC CE.

[0103] For example, the activation / deactivation of the on-demand SSB is associated with the activation / deactivation of the SCell. A MAC CE can be used to activate / deactivate the SCell, and this MAC CE can also be used to activate / deactivate the on-demand SSB; this application is not limited to this.

[0104] In some embodiments, the terminal device supports activation / deactivation of secondary cells (SCells) based on existing RRC and / or MAC CE. Meanwhile, the terminal assumes / defaults that the on-demand SSB is activated after receiving a secondary cell (SCell) activation signaling, and / or the on-demand SSB is deactivated after receiving a secondary cell (SCell) deactivation signaling.

[0105] In some embodiments, a cell may indicate / trigger / activate / enable a maximum of one on-demand SSB configuration at a time. For example, an on-demand SSB configuration may include at least the following:

[0106] The frequency of on-demand SSB;

[0107] The on-demand SSB position within the burst is similar to the parameters of ssb-PositionsInBurst;

[0108] on-demand SSB period parameters;

[0109] Subcarrier spacing in on-demand SSB;

[0110] The physical cell ID of the serving cell where the on-demand SSB is located;

[0111] The location of the on-demand SSB burst, including its time-domain location and / or frequency-domain location;

[0112] Downlink transmission power of on-demand SSB; etc.

[0113] In some embodiments, the terminal device receives multiple on-demand SSB configurations configured by the network device, and the terminal device is instructed to different on-demand SSBs, for example, by indicating / triggering / activating / enabling different on-demand SSB configurations through RRC or MAC CE to achieve on-demand SSB adjustment.

[0114] For example, a network device configures two on-demand SSBs via RRC, with on-demand SSB 1 configured with a long period and on-demand SSB 2 configured with a short period. During SCell activation, the network device needs to send frequent, dense on-demand SSBs to achieve rapid activation of the secondary cell. At this time, the network device sends RRC or MAC CE signaling to the terminal device to indicate / trigger / activate / enable on-demand SSB 2, while simultaneously not activating / deactivating / deactivating on-demand SSB 1. Once the secondary cell is fully activated, the network device only needs to send sparse, long-period on-demand SSBs for measurement. At this time, the network device sends RRC or MAC CE signaling to the terminal device to indicate / trigger / activate / enable on-demand SSB 1, while simultaneously not activating / deactivating / deactivating on-demand SSB 2.

[0115] In some embodiments, the terminal device sends capability reporting information to the network device, the capability reporting information indicating at least the maximum number of second SSB configurations that the terminal device can support / can be configured; and / or, the terminal device receives capability indication information from the network device, the capability indication information indicating at least the maximum number of second SSB configurations.

[0116] For example, the UE can report the maximum number of on-demand SSBs it can support to the base station, and the base station can respond with indication information indicating the maximum number of on-demand SSBs. Alternatively, the UE can report the maximum number of on-demand SSBs it can support to the base station, and the base station will use that maximum number of on-demand SSBs by default. Yet another example is that the base station can directly send indication information indicating the maximum number of on-demand SSBs to the terminal device.

[0117] The above illustrations illustrate some scenarios of on-demand SSB. The following sections will further explain the first and second SSB configurations. In the following description, "SSB parameters" refers to, for example, higher-level parameters related to the SSB, such as SSB-related RRC parameters, etc., but this application is not limited to these.

[0118] In some embodiments, the SSB parameters of the first SSB configuration and the second SSB configuration are the same.

[0119] For example, if the first SSB configuration and the second SSB configuration contain the same parameter names and have the same value range, other parameters can be used to indicate which configurations belong to the first SSB configuration and which belong to the second SSB configuration.

[0120] In some embodiments, the SSB parameters of the first SSB configuration and the second SSB configuration are different.

[0121] For example, the second SSB configuration can use a different IE than the first SSB configuration. The first and second SSB configurations may have the same parameter names and value ranges, but at least one parameter value may differ, such as the value of the period parameter. Alternatively, the first and second SSB configurations may have different parameter names but the same value range. Yet another example is that the first and second SSB configurations may have different parameter names and different value ranges.

[0122] In some embodiments, the SSB parameters of the first SSB configuration and the second SSB configuration are at least partially the same.

[0123] For example, the first SSB configuration may include more parameters; the second SSB configuration may include fewer parameters; the parameters in the second SSB configuration are a subset of those in the first SSB configuration. Some parameters in the second SSB configuration have the same names as some parameters in the first SSB configuration, but their values ​​are different; parameters not included in the second SSB configuration use the parameters and their values ​​from the first SSB configuration by default.

[0124] For example, if a network device only configures one SSB configuration for a terminal device, then the terminal device will use the parameters of the SSB configuration for both the first and second SSBs by default.

[0125] In some embodiments, the SSB parameters of the first SSB configuration and / or the second SSB configuration include at least one of the following: SSB period, SSB frequency, SSB position within a burst, SSB burst time-domain position, SSB subcarrier spacing, SSB subcarrier offset, and SSB downlink transmission power. This application is not limited to these; for example, the first SSB configuration may also refer to related technologies.

[0126] In some embodiments, the terminal device receives reference signal configuration information sent by the network device; the reference signal configuration information includes first SSB index information, or includes CSI-RS index information, or includes first SSB index information and second SSB index information, or includes second SSB index information.

[0127] For example, the reference signal configuration information can be RLM reference signal configuration, BLM reference signal configuration, or CSI reference signal configuration, specifically referring to the aforementioned RadioLinkMonitoringRS, BeamLinkMonitoring-r17, CSI-ResourceConfig, etc.; the first SSB index information is, for example, ssb-Index, the second SSB index information is, for example, od-SSB-Index or ssb-Index-r19, and the CSI-RS index information is, for example, csi-RS-Index, etc. This application is not limited to these.

[0128] In some embodiments, the first SSB index information corresponds to the first SSB configuration and the second SSB configuration.

[0129] For example, the time-domain structure (SSB burst structure) of the first SSB configuration and the second SSB configuration are the same, and the ssbPositionInBurst value of the SSB position parameter within the burst in the first SSB configuration and the second SSB configuration is the same. The reference signal configuration may not include a second SSB index. If the on-demand SSB is activated / enabled, the first SSB index ssb-Index included in the reference signal configuration can simultaneously indicate both the always-on SSB and the indicated / triggered / activated on-demand SSB; if the on-demand SSB is deactivated / deenabled, the first SSB index ssb-Index included in the reference signal configuration indicates the always-on SSB.

[0130] In some embodiments, the first SSB index information corresponds to a first SSB configuration, and the second SSB index information corresponds to a second SSB configuration.

[0131] For example, the time-domain structures (SSB burst structures) of the first SSB configuration and the second SSB configuration are different. The values ​​of the SSB position parameter ssbPositionInBurst within the burst contained in the first SSB configuration and the second SSB configuration are different. The reference signal configuration contains the first SSB index and the second SSB index. The first SSB index ssb-Index can correspond to always-on SSB, and the second SSB index od-ssb-Index can correspond to the on-demand SSB that is indicated / triggered / activated.

[0132] Alternatively, the time-domain structure (SSB burst structure) of the first and second SSB configurations is the same, and the ssbPositionInBurst value of the SSB position parameter within the burst in both configurations is the same. The reference signal configuration includes a first SSB index and a second SSB index. The first SSB index ssb-Index corresponds to an always-on SSB, and the second SSB index od-ssb-Index corresponds to an indicated / triggered / activated on-demand SSB. If an on-demand SSB is activated / enabled, the first SSB index ssb-Index in the reference signal configuration indicates an always-on SSB, and the second SSB index od-ssb-Index indicates an indicated / triggered / activated on-demand SSB. If an on-demand SSB is deactivated / disabled, the first SSB index ssb-Index in the reference signal configuration indicates an always-on SSB, and the second SSB index can be ignored.

[0133] In some embodiments, the terminal device is configured with at least one second SSB configuration instead of a first SSB configuration, and the terminal device confirms at least one of the following:

[0134] Assume / default SSB configured in QCL cell corresponds to second SSB configuration that is indicated / triggered / activated / enabled, and perform QCL reference according to the second SSB configuration that is indicated / triggered / activated / enabled;

[0148] In some embodiments, the terminal device is configured with a first SSB configuration and at least one second SSB configuration, and the indication information indicates that the second SSB configuration is indicated / triggered / activated / enabled, and the terminal device confirms at least one of the following:

[0149] Assume / default SSB configured in QCL cell corresponds to first SSB configuration and second SSB configuration indicated / triggered / activated, and QCL reference is performed based on first SSB configuration and second SSB configuration indicated / triggered / activated / enabled;

[0150] Assume / default RLM reference signal cell’s first SSB index or second SSB index corresponds to first SSB configuration and second SSB configuration indicated / triggered / activated / enabled, and RLM is performed according to first SSB configuration and second SSB configuration indicated / triggered / activated / enabled;

[0152] Assuming / defaulting to a first SSB index or a second SSB index in the CSI resource set or CSI resource list, corresponding to a first SSB configuration and a second SSB configuration that is indicated / triggered / activated / enabled, CSI measurements and / or CSI reporting are performed based on the first SSB configuration and the second SSB configuration that is indicated / triggered / activated / enabled.

[0153] In some embodiments, the terminal device is configured with a first SSB configuration and at least one second SSB configuration, and the indication information indicates that the second SSB configuration is indicated / triggered / activated / enabled, and the terminal device confirms at least one of the following:

[0154] Assume / default the SSB configured in the QCL cell corresponds to a first SSB configuration and a second SSB configuration that is indicated / triggered / activated, and perform QCL reference based on the first SSB configuration and the second SSB configuration that is indicated / triggered / activated;

[0155] Assume / default RLM reference signal cell: first SSB index corresponds to first SSB configuration and second SSB index corresponds to second SSB configuration that is indicated / triggered / activated / enabled; and RLM is performed according to first SSB configuration and second SSB configuration that is indicated / triggered / activated / enabled.

[0157] Assuming / defaulting to a first SSB index in the CSI resource set or CSI resource list, which corresponds to a first SSB configuration and a second SSB index, which corresponds to a second SSB configuration that is indicated / triggered / activated / enabled, CSI measurements and / or CSI reporting are performed based on the first SSB configuration and the second SSB configuration that is indicated / triggered / activated / enabled.

[0158] The above illustrations have shown some aspects of this application. The following examples will further illustrate this application.

[0159] In some embodiments, the terminal device performs CSI measurements and reporting, Radio Link Monitoring (RLM), and Beam Link Monitoring (BLM) based on Always-on SSB and / or OD-SSB. A serving cell supporting OD-SSB secondary cell operation may or may not transmit Always-on SSB, depending on the base station implementation.

[0160] In some cases, the serving cell supporting OD-SSB secondary cell operation does not have an always-on SSB, meaning there is no periodically transmitted SSB, only OD-SSB. When the serving cell has service requirements or a secondary cell is configured or activated, the network device indicates / activates / enables / triggers / starts OD-SSB transmission on that cell; when the serving cell has no service requirements, the network device deactivates / de-enables / stops OD-SSB transmission on that cell. Terminal devices can perform QCL reference, CSI measurement and reporting, radio link monitoring, and beam link monitoring based on the indicated / activated / enabled / triggered OD-SSB.

[0161] The terminal device is configured with at least one OD-SSB configuration and receives OD-SSB indication information. This indication information, based on RRC or MAC CE, indicates the activation / indication / triggering / enabling state or deactivation / deactivation state of at least one OD-SSB configuration. The terminal device determines the QCL source reference signal, CSI measurement reference signal, radio link monitoring reference signal, and beam link monitoring reference signal based on the activated / indicated / triggered / enabling OD-SSB configuration. At any given time, at most one OD-SSB can be activated / indicated / triggered / enabling in the serving cell.

[0162] In this case, the terminal device confirms at least one of the following behaviors:

[0163] --The terminal device assumes / defaults that the SSB configured in the QCL-Info IE corresponds to the activated / indicated / triggered / enabled OD-SSB configuration, and the terminal device performs QCL source reference based on the activated / indicated / triggered / enabled OD-SSB;

[0164] --The terminal device assumes / defaults to the SSB index 'ssb-index' in the RLM Reference Signal Resource IE (RadioLinkMonitoringRS) indicating the activated / indicated / triggered / enabled OD-SSB configuration; the terminal device performs radio link monitoring based on the activated / indicated / triggered / enabled OD-SSB corresponding to 'ssb-index'.

[0165] --The terminal device assumes / defaults to the SSB index 'ssb-index' in the BLM reference signal resource IE (BeamLinkMonitoringRS) indicating the activated / indicated / triggered / enabled OD-SSB configuration; the terminal device performs beam link monitoring based on the activated / indicated / triggered / enabled OD-SSB corresponding to 'ssb-index'.

[0166] --The terminal device assumes / defaults to the configuration of the SSB index 'ssb-index' in the CSI measurement signal resource IE (csi-SSB-ResourceSet or csi-SSB-ResourceList) to indicate that the OD-SSB is activated / indicated / triggered / enabled; the terminal device performs CSI measurements and reports based on the activated / indicated / triggered / enabled OD-SSB corresponding to 'ssb-index'.

[0167] Table 6 shows an example of the relevant description.

[0168] Table 6

[0169] In some cases, the serving cell supporting OD-SSB secondary cell operation has an always-on SSB, meaning there is a periodically transmitted SSB. For example, to save energy, the always-on SSB is configured with a longer period. When the serving cell has service needs or when the secondary cell is configured / activated, the network device can activate the OD-SSB for rapid secondary cell activation and / or measurements during secondary cell activation. Terminal devices can simultaneously perform QCL source reference, CSI measurement and reporting, radio link monitoring, and beam link monitoring based on always-on SSB and / or OD-SSB.

[0170] The terminal device is configured with an always-on SSB and at least one OD-SSB configuration, and receives OD-SSB indication information. This indication information, based on RRC or MAC CE, indicates the active / indicating / triggered / enabled state, or deactivated / disabled state, of at least one OD-SSB configuration. The terminal device determines the QCL source reference signal, CSI measurement reference signal, radio link monitoring reference signal, and beam link monitoring reference signal based on the activated / indicating / triggered / enabled OD-SSB configuration.

[0171] In some examples, the terminal device does not receive OD-SSB indication information, or the terminal device receives OD-SSB indication information indicating that OD-SSB is in a deactivated / disabled state. In this case, the terminal device confirms at least one of the following behaviors:

[0172] --The terminal device assumes / defaults that the SSB configured in the QCL-Info IE corresponds to the always-on SSB, and the terminal device uses the always-on SSB for QCL source reference;

[0173] --The terminal device assumes / defaults to configuring the SSB index 'ssb-index' in the RLM Reference Signal Resource IE (RadioLinkMonitoringRS) to indicate always-on SSB; the terminal device performs radio link monitoring based on the always-on SSB corresponding to 'ssb-index';

[0174] --The terminal device assumes / defaults to configuring the SSB index 'ssb-index' in the BLM reference signal resource IE (BeamLinkMonitoringRS) to indicate always-on SSB; the terminal device performs beam link monitoring based on the always-on SSB corresponding to 'ssb-index';

[0175] --The terminal device assumes / defaults to configuring the SSB index 'ssb-index' in the CSI measurement signal resource IE (csi-SSB-ResourceSet or csi-SSB-ResourceList) to indicate always-on SSB; the terminal device performs CSI measurements and reports based on the always-on SSB corresponding to 'ssb-index'.

[0176] The always-on SSB can be the CD-SSB of the serving cell.

[0177] Table 7 shows an example of the relevant description.

[0178] Table 7

[0179] Table 8 shows an example of the relevant description.

[0180] Table 8

[0181] In other examples, the terminal device receives OD-SSB indication information indicating that the OD-SSB is in an activated / indicated / triggered / enabled state. In this case, the terminal device confirms at least one of the following behaviors:

[0182] --The terminal device assumes / defaults that the SSB configured in the QCL-Info IE corresponds to the activated / indicated / triggered / enabled OD-SSB configuration; the terminal device performs QCL source reference based on the activated / indicated / triggered / enabled OD-SSB;

[0183] --The terminal device assumes / defaults to the SSB index 'ssb-index' in the RLM Reference Signal Resource IE (RadioLinkMonitoringRS) indicating the activated / indicated / triggered / enabled OD-SSB configuration; the terminal device performs radio link monitoring based on the activated / indicated / triggered / enabled OD-SSB corresponding to 'ssb-index'.

[0184] --The terminal device assumes / defaults to the SSB index 'ssb-index' in the BLM reference signal resource IE (BeamLinkMonitoringRS) indicating the activated / indicated / triggered / enabled OD-SSB configuration; the terminal device performs beam link monitoring based on the activated / indicated / triggered / enabled OD-SSB corresponding to 'ssb-index'.

[0185] --The terminal device assumes / defaults to the configuration of the SSB index 'ssb-index' in the CSI measurement signal resource IE (csi-SSB-ResourceSet or csi-SSB-ResourceList) to indicate that the OD-SSB is activated / indicated / triggered / enabled; the terminal device performs CSI measurements and reports based on the activated / indicated / triggered / enabled OD-SSB corresponding to 'ssb-index'.

[0186] Table 9 shows an example of the relevant description.

[0187] Table 9

[0188] In some other examples, the terminal device receives OD-SSB indication information indicating that the OD-SSB is in an activated / indicated / triggered enabled state. In this case, the terminal device confirms at least one of the following behaviors:

[0189] --The terminal device assumes / defaults that the SSB configured in the QCL-Info IE corresponds to the always-on SSB and the activated / indicated / triggered / enabled OD-SSB configuration; the terminal device performs QCL source reference based on the always-on SSB and the activated / indicated / triggered / enabled OD-SSB.

[0190] --The terminal device assumes / defaults to configuring the SSB index 'ssb-index' in the RLM Reference Signal Resource IE (RadioLinkMonitoringRS) to indicate the always-on SSB and the activated / indicated / triggered / enabled OD-SSB configuration; the terminal device performs radio link monitoring based on the always-on SSB and the activated / indicated / triggered / enabled OD-SSB corresponding to 'ssb-index'.

[0191] --The terminal device assumes / defaults to configuring the SSB index 'ssb-index' in the BL reference signal resource IE (BeamLinkMonitoringRS) to indicate the always-on SSB and the activated / indicated / triggered / enabled OD-SSB configuration; the terminal device performs beam link monitoring based on the always-on SSB and the activated / indicated / triggered / enabled OD-SSB corresponding to 'ssb-index'.

[0192] --The terminal device assumes / defaults to configuring the SSB index 'ssb-index' in the CSI measurement signal resource IE (csi-SSB-ResourceSet or csi-SSB-ResourceList) to indicate the always-on SSB and the activated / indicated / triggered / enabled OD-SSB configuration; the terminal device performs CSI measurements and reports based on the always-on SSB and the activated / indicated / triggered / enabled OD-SSB corresponding to 'ssb-index'.

[0193] Table 10 shows an example of the relevant description.

[0194] Table 10

[0195] In some examples, the SSB index 'ssb-index' indicates both the OD-SSB and the always-on SSB. The terminal device assumes that the OD-SSB and the always-on SSB are configured with the same SSB parameters, which include at least one of the following: the frequency parameters of the OD-SSB, the SSB position parameters within the OD-SSB burst, the subcarrier spacing of the OD-SSB, the downlink transmission power of the OD-SSB, etc. Therefore, an OD-SSB burst and an always-on SSB burst have identical structures. In this case, an SSB index (e.g., ssb-index) can be used to indicate both the OD-SSB and the always-on SSB.

[0196] Therefore, when the serving cell has an OD-SSB, the terminal equipment can determine how to perform QCL source reference, CSI measurement and reporting, radio link monitoring and beam link monitoring based on the OD-SSB, thus solving the problems of QCL source reference, CSI measurement, RLM and BFD / BFR in the operation of OD-SSB secondary cells in network energy saving.

[0197] In some embodiments, the terminal device receives configuration information / parameters and performs CSI measurements and reporting, Radio Link Monitoring (RLM), and Beam Link Monitoring (BLM) based on always-on SSB and / or OD-SSB and / or configuration information / parameters.

[0198] For example, the terminal device receives configuration information / parameters used to configure / indicate the OD-SSB index. Based on the OD-SSB index, the terminal device determines the OD-SSB-based CSI measurement reference signal and / or radio link reference signal and / or beam link reference signal to perform corresponding CSI measurements and reporting, radio link monitoring, and beam link monitoring. This OD-SSB index may be included in the CSI measurement reference signal configuration and / or radio link reference signal configuration and / or beam link reference signal configuration.

[0199] For example, configuration information / parameters could be named od-ssb-index, etc. The existing protocol uses 'ssb-index' to indicate the index of always-on SSB / CD-SSB, while the configuration information / parameters indicate the index of OD-SSB.

[0200] Table 11 shows an example of the relevant description.

[0201] Table 11

[0202] Table 12 shows another example of the relevant description.

[0203] Table 12

[0204] In some examples, the terminal device assumes that the SSB references included in the OD-SSB configuration and the always-on SSB configuration can be the same, partially the same, or different. The SSB parameters include at least one of the following: the frequency parameters of the OD-SSB, the SSB position parameters within the OD-SSB burst, the subcarrier spacing of the OD-SSB, the downlink transmission power of the OD-SSB, etc.

[0205] For example, OD-SSB and always-on SSB are configured with different SSB parameters: OD-SSB and always-on SSB are configured with different ssb-PositionsInBurst parameters. OD-SSB bursts transmit SSBs with ssb-index=0 and 1, while always-on SSB bursts transmit SSBs with ssb-index=2 and 3.

[0206] For example, as shown in Figure 3, when the frequency is less than 3 GHz and the SCS is 15 kHz, there are four candidate SSB times, from left to right: ssb-index = 0, 1, 2, and 3. In the example above, the OD-SSB is configured with ssb-PositionsInBurst = 1100, indicating that the SSBs with ssb-index = 0 and 1 are transmitted within the OD-SSB burst, i.e., the first two SSBs. The always-on SSB is configured with ssb-PositionsInBurst = 0011, indicating that the SSBs with ssb-index = 2 and 3 are transmitted within the OD-SSB burst, i.e., the last two SSBs.

[0207] In some embodiments, the serving cell that supports OD-SSB secondary cell operation may or may not transmit always-on SSB, depending on the base station implementation.

[0208] In some examples, the serving cell supporting OD-SSB secondary cell operation does not have an always-on SSB, meaning there is no periodically transmitted SSB, only OD-SSB. When the serving cell has service requirements or a secondary cell is configured or activated, the network device indicates / activates / enables / triggers / starts OD-SSB transmission on that cell; when the serving cell has no service requirements, the network device deactivates / de-enables / stops OD-SSB transmission on that cell. Terminal devices can perform QCL source reference, CSI measurement and reporting, radio link monitoring, and beam link monitoring based on the indicated / activated / enabled / triggered OD-SSB.

[0209] For example, if the terminal device is not configured with always-on SSB, but is configured with at least one OD-SSB configuration, and receives OD-SSB indication information based on RRC or MAC CE, this information indicates the activation / indication / triggering / enabling state or deactivation / deactivation state of at least one OD-SSB configuration. At any given time, at most one OD-SSB in the serving cell can be activated / indicated / triggered / enabled. Additionally, the terminal device also receives configuration information / parameters. The terminal device determines the QCL source reference signal, CSI measurement reference signal, radio link monitoring reference signal, and beam link monitoring reference signal based at least on the activated / indicated / triggered / enabled OD-SSB configuration and the configuration information / parameters.

[0210] The terminal device determines at least one of the following behaviors:

[0217] In some examples, the serving cell supporting OD-SSB secondary cell operation has an always-on SSB, meaning there is a periodically transmitted SSB. For example, to save energy, the always-on SSB is configured with a longer period. When the serving cell has service needs or when the secondary cell is configured / activated, the network device can activate the OD-SSB for rapid secondary cell activation and / or measurements during secondary cell activation. At the same time, the terminal device can perform QCL source reference, CSI measurement and reporting, radio link monitoring, and beam link monitoring based on the indicated / activated / enabled / triggered OD-SSB and always-on SSB.

[0218] For example, the terminal device is configured with always-on SSB and at least one OD-SSB configuration. It receives OD-SSB indication information, based on RRC or MAC CE, to indicate the activation / indication / triggering / enabling or deactivation / deactivation state of at least one OD-SSB configuration. At any given time, at most one OD-SSB in the serving cell can be activated / indicated / triggered / enabled. Furthermore, the terminal device receives configuration information / parameters. Based at least on always-on SSB, the activated / indicated / triggered / enabled OD-SSB configuration, and the configuration information / parameters, the terminal device determines the QCL source reference signal, CSI measurement reference signal, radio link monitoring reference signal, and beam link monitoring reference signal.

[0219] In this case, the terminal device confirms at least one of the following behaviors:

[0220] --The terminal device assumes / defaults that the SSB configured in the QCL-Info IE corresponds to always-on SSB, and the terminal device uses always-on SSB for QCL source reference; or, the terminal device assumes / defaults that the SSB configured in the QCL-Info IE corresponds to OD-SSB, and the terminal device uses OD-SSB for QCL source reference; or, the terminal device assumes / defaults that the SSB configured in the QCL-Info IE corresponds to both always-on SSB and OD-SSB, and the terminal device uses both always-on SSB and OD-SSB for QCL source reference.

[0221] --The terminal device assumes / defaults to configuring the SSB index 'ssb-index' in the RLM Reference Signal Resource IE (RadioLinkMonitoringRS) to indicate an always-on SSB; the configuration information / parameter (OD-SSB index 'od-ssb-index') indicates the activated / indicated / triggered / enabled OD-SSB. If the OD-SSB is not activated / indicated / triggered / enabled, the terminal device can perform radio link monitoring based on the always-on SSB corresponding to 'ssb-index'; if the OD-SSB is activated / indicated / triggered / enabled, the terminal device can perform radio link monitoring based on the always-on SSB corresponding to 'ssb-index' and / or the OD-SSB corresponding to the configuration information / parameter 'od-ssb-index'.

[0222] --The terminal device assumes / defaults to configuring the SSB index 'ssb-index' in the BLM reference signal resource IE (BeamLinkMonitoringRS) to indicate an always-on SSB; the configuration information / parameter (OD-SSB index 'od-ssb-index') indicates the activated / indicated / triggered / enabled OD-SSB. If the OD-SSB is not activated / indicated / triggered / enabled, the terminal device can perform beam link monitoring based on the always-on SSB corresponding to 'ssb-index'; if the OD-SSB is activated / indicated / triggered / enabled, the terminal device can perform beam link monitoring based on the always-on SSB corresponding to 'ssb-index' and / or the OD-SSB corresponding to the configuration information / parameter 'od-ssb-index'.

[0223] --The terminal device assumes / defaults to configuring the SSB index 'ssb-index' in the CSI measurement signal resource IE (csi-SSB-ResourceSet or csi-SSB-ResourceList) to indicate an always-on SSB; the configuration information / parameter (OD-SSB index 'od-ssb-index') indicates the activated / indicated / triggered / enabled OD-SSB. If the OD-SSB is not activated / indicated / triggered / enabled, the terminal device can perform CSI measurements and reporting based on the always-on SSB corresponding to 'ssb-index'; if the OD-SSB is activated / indicated / triggered / enabled, the terminal device can perform CSI measurements and reporting based on the always-on SSB corresponding to 'ssb-index' and / or the OD-SSB corresponding to the configuration information / parameter 'od-ssb-index'.

[0224] Table 14 shows an example of the relevant description.

[0225] Table 14

[0226] In some embodiments, the terminal device determines / selects to perform QCL source referencing and / or measurement based on always-on SSB based on network indication information and / or the terminal device's default / assumption / self-judgment, wherein the configuration / indication information or the terminal's default / assumption information includes at least one of the following:

[0227] --The SSB configured in QCL-Info IE is the OD-SSB that is activated / indicated / triggered / enabled;

[0228] --The SSB index 'ssb-index' configured in the RLM Reference Signal Resource IE (RadioLinkMonitoringRS) indicates the always-on SSB configuration;

[0229] --The SSB index 'ssb-index' configured in the BLM reference signal resource IE (BeamLinkMonitoringRS) indicates the always-on SSB configuration;

[0230] --Configuration of the SSB index 'ssb-index' in the CSI measurement signal resource IE (csi-SSB-ResourceSet or csi-SSB-ResourceList) indicates always-on SSB configuration;

[0231] For example, the always-on SSB can be the CD-SSB of the serving cell.

[0232] In some embodiments, the terminal device determines / selects QCL source referencing and / or measurement based on OD-SSB based on network indication information or the terminal device's default / assumption / self-judgment. The configuration / indication information or the terminal device's default / assumption information includes at least one of the following:

[0233] --The SSB configured in QCL-Info IE is the OD-SSB that is activated / indicated / triggered / enabled;

[0234] --The SSB index 'ssb-index' configured in the RLM Reference Signal Resource IE (RadioLinkMonitoringRS) indicates the OD-SSB configuration that is activated / indicated / triggered / enabled;

[0235] --The SSB index 'ssb-index' configured in the BLM reference signal resource IE (BeamLinkMonitoringRS) indicates the OD-SSB configuration that is activated / indicated / triggered / enabled;

[0236] --The SSB index 'ssb-index' configured in the CSI Measurement Signal Resource IE (csi-SSB-ResourceSet or csi-SSB-ResourceList) indicates the OD-SSB configuration that is activated / indicated / triggered / enabled.

[0237] In some embodiments, the terminal device determines / selects to perform QCL source reference and / or measurement based on both always-on SSB and OD-SSB, based on network device configuration / instruction information or the terminal device's default / assumption / self-judgment.

[0238] For example, the terminal device assumes that the OD-SSB and always-on SSB are configured with the same SSB parameters, which include at least one of the following: the OD-SSB frequency parameters, the SSB position parameters within the OD-SSB burst, the subcarrier spacing of the OD-SSB, the downlink transmission power of the OD-SSB, etc. Therefore, an OD-SSB burst and an always-on SSB burst have identical structures. In this case, an SSB index (ssb-index) can be used to indicate both the OD-SSB and always-on SSB. Therefore, the configuration / indication information or the terminal device's default / assumption information includes at least one of the following:

[0239] --The SSB configured in QCL-Info IE is OD-SSB and always-on SSB;

[0240] --The SSB index 'ssb-index' configured in the RLM reference signal resource IE (RadioLinkMonitoringRS) indicates OD-SSB and always-on SSB;

[0241] --The SSB index 'ssb-index' configured in the BLM reference signal resource IE (BeamLinkMonitoringRS) indicates OD-SSB and always-on SSB;

[0242] --Configure the SSB index 'ssb-index' in the CSI Measurement Signal Resource IE (csi-SSB-ResourceSet or csi-SSB-ResourceList) to indicate OD-SSB and always-on SSB.

[0243] For example, the terminal device assumes that the OD-SSB and always-on SSB are configured with different SSB parameters. These parameters include at least one of the following: the OD-SSB frequency parameter, the SSB position parameter within the OD-SSB burst, the subcarrier spacing of the OD-SSB, the downlink transmission power of the OD-SSB, etc. For instance, the OD-SSB and always-on SSB are configured with different ssb-PositionsInBurst parameters; the OD-SSB burst transmits SSBs with ssb-index = 0 and 1, while the always-on SSB burst transmits SSBs with ssb-index = 2 and 3.

[0244] For example, the terminal device assumes that the SSB index 'ssb-index' represents always-on SSB, and at the same time, the network device configures a first SSB parameter, which is used to indicate the SSB index of OD-SSB;

[0245] For example, the terminal device assumes that the SSB index 'ssb-index' represents OD-SSB, and the network device configures a first SSB parameter, which is used to indicate the SSB index of always-on SSB.

[0246] The first SSB parameter can be named OD-ssb-index or additional-ssb-index. The first SSB parameter can be included in the RLM reference signal resource IE (RadioLinkMonitoringRS), and / or the BLM reference signal resource IE (BeamLinkMonitoringRS), and / or the CSI measurement signal resource IE (csi-SSB-ResourceSet or csi-SSB-ResourceList).

[0247] In some examples, the SSB index 'ssb-index' indicates always-on SSB, and the first SSB parameter OD-ssb-index is used to indicate the SSB index of OD-SSB. For example, configuration / indication information or terminal device default / assumption information includes at least one of the following:

[0248] --The SSB index 'ssb-index' configured in the RLM Reference Signal Resource IE (RadioLinkMonitoringRS) indicates always-on SSB, and 'OD-ssb-index' indicates the OD-SSB configuration that is activated / indicated / triggered / enabled;

[0249] --The SSB index 'ssb-index' configured in the BLM reference signal resource IE (BeamLinkMonitoringRS) indicates always-on SSB, and 'OD-ssb-index' indicates the OD-SSB configuration that is activated / indicated / triggered / enabled;

[0250] --The SSB index 'ssb-index' configured in the CSI Measurement Signal Resource IE (csi-SSB-ResourceSet or csi-SSB-ResourceList) indicates always-on SSB, and 'OD-ssb-index' indicates the OD-SSB configuration that is activated / indicated / triggered / enabled.

[0251] Therefore, the terminal equipment can determine which SSB configuration to use for QCL source reference, CSI measurement, RLM, and BFD / BFR when both always-on SSB and OD-SSB exist simultaneously, thus solving the QCL source reference, CSI measurement, RLM, and BFD / BFR issues in OD-SSB secondary cell operation during network energy saving.

[0252] The above illustrative description illustrates measurements based on the first SSB configuration and / or the second SSB configuration. The following section further explains some aspects of the CSI reporting configuration. The following embodiments can be combined with the above embodiments or implemented independently.

[0253] In some embodiments, the terminal device receives at least one first SSB configuration and / or at least one second SSB configuration sent by the network device; receives indication information sent by the network device for indicating / triggering / activating / enabling one of the at least one second SSB configurations; and the terminal device performs CSI measurement and CSI reporting according to the at least one first SSB configuration and / or the one second SSB configuration.

[0254] In some embodiments, the association / binding of periodic CSI reporting configuration and the second SSB configuration is not supported, or the periodic CSI reporting configuration cannot be associated / bound to the second SSB configuration, or the terminal device does not expect to receive periodic CSI reporting configuration associated / bound to the second SSB configuration, or the terminal device does not expect periodic CSI reporting configuration to be associated / bound to the second SSB configuration.

[0255] For example, existing protocols do not support the association / binding of periodic CSI reporting configuration and non-periodic / semi-persistent CSI-RS resource configuration. The OD-SSB transmission introduced in Rel-19 also starts transmission after activation at a certain time, and deactivates and stops transmission at a certain time after a period of transmission. OD-SSB transmission is similar to semi-persistent CSI-RS transmission, while periodic CSI reporting configuration requires association / binding with periodically transmitted CSI-RS or SSB. Therefore, in the embodiments of this application, network devices do not support the association / binding of periodic CSI reporting configuration and OD-SSB configuration, or the periodic CSI reporting configuration cannot be associated / bound with OD-SSB resources, or the terminal device does not expect to configure periodic CSI reporting configuration bound / associated with OD-SSB, or the terminal device does not expect periodic CSI reporting configuration to be associated / bound with OD-SSB.

[0256] In some embodiments, the non-periodic CSI reporting configuration is associated with / bound to the second SSB configuration, or the semi-continuous CSI reporting configuration is associated with / bound to the second SSB configuration.

[0257] The above embodiments are merely illustrative examples of embodiments of this application, but this application is not limited thereto, and appropriate modifications can be made based on the above embodiments. For example, the above embodiments can be used alone, or one or more of the above embodiments can be combined.

[0258] As can be seen from the above embodiments, in some scenarios of wireless communication applications (such as energy-saving mode), the terminal device performs measurements according to the first SSB configuration and / or the second SSB configuration. As a result, the network device and the terminal device can quickly and flexibly adjust the SSB transmission, which can improve network gain (such as energy-saving gain) and ensure the normal transmission of the terminal device.
