Description

Configuration method and apparatus TECHNICAL FIELD

[0001] Embodiments of the present application relate to the field of communication technology. BACKGROUND

[0002] As an important part of global new infrastructure construction, 5G communication networks have developed rapidly in the world in recent years. Network scale is getting larger and larger, and energy consumption of operators continues to grow. For example, according to the data released by the Ministry of Industry and Information Technology of China, energy consumption will increase by about 80% in 2022 compared with 2015.

[0003] With the construction of 5G and the large-scale commercialization of 5G active antenna processing units (AAU), compared with the remote radio unit (RRU) mainly used in 3G and 4G, the energy consumption of AAU will increase exponentially due to its high power consumption. 5G defines three major service types: enhanced mobile broadband (eMBB), massive machine type of communication (mMTC), and ultra reliable low latency communication (URLLC), which makes the bursty service of 5G small packets increase continuously, and the base station works uninterruptedly for 24 hours. The daily energy consumption of 5G sites will be more than twice that of 4G.

[0004] 3GPP introduced key technologies such as massive MIMO and larger radio frequency bandwidth in the 5G era, and 5G supports higher data rates and larger data traffic, requiring more transmission bandwidth. The deployment of high-frequency bands will also be the main frequency band for future expansion of 5G. The transmission characteristics of high-frequency bands limit the coverage of the site, so that 5G sites are deployed more densely, and the energy consumption brought by increasing sites will bring huge operating cost pressure to operators. Therefore, network energy saving is of great significance to save operating costs, and network energy saving has become one of the problems to be solved in the 5G and even 6G era.

[0005] In order to achieve energy saving, network devices can perform energy saving processing in time domain, frequency domain, spatial domain and / or energy domain according to network load conditions. For example, in terms of spatial domain and energy domain, network devices can close part of the antennas when the load is low to achieve the purpose of energy saving, and in terms of time domain, network devices can adjust the period or time domain position of cell common reference signals (such as SSB / SIB) in the case of few users and small load to achieve the purpose of network device energy saving.

[0006] It should be noted that the above introduction to the technical background is only for the convenience of clearly and completely describing the technical scheme of the present application and facilitating the understanding of those skilled in the art. The above technical scheme cannot be considered as known to those skilled in the art merely because it is described in the background section of the present application.

[0007] SUMMARY

[0008] The inventor finds that, in the time domain, for a serving cell which is only a secondary cell, when there is no load on the serving cell and no data transmission is needed, the network device can turn off / stop the transmission of the common reference signal (such as SSB) of the serving cell to achieve the purpose of energy saving; when there is load on the serving cell and data transmission is needed, the network device activates / triggers the common reference signal of the serving cell through signaling for L1 / L3 measurement of the terminal device, fast activation of the secondary cell and other operations. This energy-saving method of turning on or off the common reference signal transmission according to the change of traffic can not only ensure the normal communication of the terminal device, but also achieve the purpose of network device energy saving.

[0054] The following describes the scenarios of the embodiments of the present application by way of examples, but the present application is not limited thereto.

[0055] FIG. 1 is a schematic diagram of a communication system according to an embodiment of the present application, which schematically illustrates a case taking a terminal equipment and a network device as an example. As shown in FIG. 1, the communication system 100 can include a network device 101 and terminal equipments 102 and 103. For simplicity, FIG. 1 only takes two terminal equipments and one network device as an example for illustration, but the embodiments of the present application are not limited thereto.

[0056] In the embodiments of the present application, the network device 101 and the terminal devices 102 and 103 can perform existing services or future implementable service transmission. For example, the services can include, but are not limited to, enhanced mobile broadband (eMBB), massive machine type communication (mMTC), and ultra-reliable and low-latency communication (URLLC), etc.

[0057] It is worth noting that FIG. 1 shows that both terminal devices 102 and 103 are within the coverage of the network device 101, but the present application is not limited thereto. Both terminal devices 102 and 103 can be outside the coverage of the network device 101, or one terminal device 102 is within the coverage of the network device 101 and the other terminal device 103 is outside the coverage of the network device 101.

[0058] System message design is one of the important concepts in wireless communication system, cell level system message is mainly to configure cell camping, provide user access, interoperation, etc. 5G NR simplifies system message to some extent, compared with 4G, synchronization signal and system message design are different, so it is necessary to re-cognize.

[0059] Unlike 4G, which separates the downlink synchronization signal and physical broadcast channel of the cell, 5G couples the cell synchronization signal (SS) and the physical broadcast channel (PBCH) to some extent in the form of SS / PBCH resource blocks, which is simply referred to as synchronization signal block (SSB).

[0060] FIG. 2 is a schematic diagram of the time-frequency structure of SSB. As shown in FIG. 2, the SSB occupies 20 consecutive physical resource blocks (PRBs) in the frequency domain in 5G NR, a total of 240 consecutive resource elements (REs), of which the synchronization signal (including the primary synchronization signal PSS and the secondary synchronization signal SSS) occupies 127 consecutive REs in the first and third OFDM symbols of the SSB, respectively. The SSB frequency domain center position can be flexibly configured and adjusted.

[0061] After the UE synchronizes with the SSB through frequency search, the master information block (MIB) in the physical broadcast channel is decoded. In the LTE system, in addition to configuring the MIB, the cell also configures SIB1 according to a fixed transmission period, and transmits the necessary parameters required for parsing SIB2 to SIBN through SIB1. 5G NR provides an optimization mechanism for system message configuration, i.e., on-demand configuration. In principle, SIB1 does not have to be configured according to a fixed period. However, SIB1 transmits information related to cell selection, which needs to be configured semi-statically through RRC signaling even if it is not configured according to a fixed period. Because the content carried by PDCCH is limited, and the cell-level system message generally does not change dynamically, PDCCH is generally not used to carry system messages in design. 5G NR achieves semi-static configuration through RRC messages.

[0062] The design concept of "on-demand configuration" of system messages in 5G NR greatly reduces the resource occupation overhead of system messages, and the terminal device can also reduce the power consumption caused by periodic system message detection to a certain extent. In 5G NR, the parameter ssb-SubcarrierOffset in MIB is used to determine whether SIB1 is configured in the PDCCH common search space CORESET#0. This parameter represents the frequency domain starting position of the SSB relative to the subcarrier offset of the common PRB. For 5G cell carriers in the FR1 (sub-6 GHz) frequency band, the UE combines the PBCH additional 1-bit joint time domain load to determine the subcarrier offset of the SSB relative to the common PRB. The value range is 0-31. If the value is not greater than 23, the UE considers that the cell is configured with system message SIB1, otherwise the SIB1 content does not appear in the form of a system message. For 5G cell carriers in the FR2 frequency band, the UE only determines the subcarrier offset through the parameter ssb-SubcarrierOffset. The value range is 0-15. If the value is not greater than 11, the UE considers that the cell is configured with system message SIB1, otherwise the SIB1 content does not appear in the form of a system message. If this parameter is not configured, the UE determines the frequency domain subcarrier offset of the SSB through frequency search.

[0063] 5G NR introduces the concept of beamformed narrow beams, the pattern of which is not explicitly specified. In a SSB transmission period, the beamformed narrow beams transmitted by SSBs in different candidate transmission moments are different. The protocol stipulates that the maximum SSB transmission is 80 ms, which means that the high-layer content carried by SSB will not change at least in the 80 ms high-layer scheduling period. The physical layer transmission period of SSB can be configured by the high-layer parameter ssb-periodicityServingCell, with a value range of {5 ms, 10 ms, 20 ms, 40 ms, 80 ms, 160 ms}. The main consideration for setting the SSB repetition period is to match the SSB transmission rate. The larger the period, the less time-domain resources occupied by SSB, and the UE listening period may be correspondingly lengthened. If this parameter is not configured, the UE defaults to a SSB transmission period of 5 ms. The protocol stipulates that during initial cell selection, the UE can assume a period of 20 ms to search for a half frame containing SSBs, which provides a theoretical basis for optimizing the UE's downlink synchronization search mechanism.

[0064] For different subcarrier spacings, the candidate positions of SSB per transmission half frame are defined as follows:

[0065] A: subcarrier spacing 15 kHz, for NR carrier frequency not greater than 3 GHz in FR1 band, the candidate transmission moment of SSB can be configured in {2, 8} OFDM positions of 0, 1 time slot, so there are 4 candidate moments; and for NR carrier frequency greater than 3 GHz in FR1 band, the candidate transmission moment of SSB is configured in {2, 8} OFDM positions of 0, 1, 2, 3 time slots, a total of 8 candidate moments;

[0066] B: subcarrier spacing 30 kHz, for NR carrier frequency not greater than 3 GHz in FR1 band, the candidate transmission moment of SSB can be configured in {4, 8, 16, 20} OFDM positions starting from 0 time slot, so there are 4 candidate moments; and for NR carrier frequency greater than 3 GHz in FR1 band, the candidate transmission moment of SSB is configured in {4, 8, 16, 20} OFDM positions starting from 0, 2 time slots, a total of 8 candidate moments;

[0067] C: subcarrier spacing 30 kHz, for NR carrier frequency not greater than 3 GHz in FR1 band, the candidate transmission time of SSB can be configured in {2, 8} OFDM positions of 0, 1 slot, so there are 4 candidate time; for NR carrier frequency greater than 3 GHz in FR1 band, the candidate transmission time of SSB is configured in {2, 8} OFDM positions of 0, 1, 2, 3 slots, a total of 8 candidate time; for NR carrier frequency not greater than 2.4 GHz in FR1 band in 5G TDD spectrum mode, the candidate transmission time of SSB can be configured in {2, 8} OFDM positions of 0, 1 slot, so there are 4 candidate time; for NR carrier frequency greater than 2.4 GHz in FR1 band, the candidate transmission time of SSB is configured in {2, 8} OFDM positions of 0, 1, 2, 3 slots, a total of 8 candidate time;

[0068] D: subcarrier spacing 120 kHz, for NR carrier frequency in FR2 band, the candidate transmission time of SSB is configured in {4, 8, 16, 20} OFDM positions of 0, 2, 4, 6, 10, 12, 14, 16, 20, 22, 24, 26, 30, 32, 34, 36 slots respectively, a total of 64 candidate time.

[0069] E: subcarrier spacing 240 kHz, for NR carrier frequency in FR band, the candidate transmission time of SSB is configured in {8, 12, 16, 20, 32, 36, 40, 44} OFDM positions of 0, 4, 8, 12, 20, 24, 28, 32 slots respectively, a total of 64 candidate time.

[0070] For SSB candidate position pattern ABCDE transmitted within a half frame, UE can determine the specific index position of the current transmitted SSB by decoding PBCH payload bits, for half frame containing 4 SSB candidate transmission positions, the index is determined by 2 low significant bits (LSB), while half frame containing 8 SSB candidate transmission positions, the index is determined by 3 low significant bits (LSB), in both cases, PBCH index is exactly one-to-one corresponding to the pseudo-random sequence initial sequence index of DMRS in SSB, UE does not directly know when determining 2 low significant bits or 3 low significant bits by decoding PBCH transmission bits, but indirectly through decoding DMRS logical mapping. Half frame contains 64 SSB candidate transmission positions, the index of DMRS in the transmitted SSB is mapped by 3 low significant bits (8 SSB cycles), UE determines the transmission index of SSB by combining 3 low significant bits (LSB) and 3 additional high significant bits (MSB) of PBCH payload. PBCH payload is 32 bits, including 23 bits carrying RRC content, of which 6 bits are high 6 bits for calculating radio frame, in addition to the 23 bits, physical layer additionally 4 bits related to transmission time as low 4 bits for calculating radio frame, 1 bit as half frame identification in radio frame, 3 bits as high 3 bits for determining SSB index, the remaining 1 bit is not specified in the protocol, MAC layer entity fills in order to align with the transmission byte.

[0071] FIG. 3 is a schematic diagram of SSB candidates. As shown in FIG. 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.

[0072] The SSB pattern gives the possible candidate positions of SSB within a SSB burst set and the maximum value L of SSB max The actual number of activated SSBs can be less than L max The base station notifies the UE of which SSBs are activated for use through the high-layer parameter ssb-PositionInBurst in SIB1 or UE-specific RRC signaling. The SSB-related RRC parameters can refer to related technologies.

[0073] The embodiment of the present application supports SSB-based CSI measurement, that is, supports the association / binding of CSI reporting and SSB measurement resources. Table 1 shows an example of CSI resource configuration, as shown in Table 1, nzp-CSI-RS-SSB can configure nzp-CSI-RS resources or SSB resources; csi-SSB-ResourceSetList is the SSB resource used for CSI measurement.

[0074] Table 1

[0075] The above illustrates the SSB-related content of the embodiment of the present application, and the present application is not limited thereto, and reference can be made to related technologies. In addition, the above content is part of the embodiment of the present application, and can be combined with the following embodiments.

[0076] The network device can configure SSB for the secondary cell, and the terminal device performs measurement and synchronization operation based on the SSB configured with a fixed period; in addition, the network device can also not configure SSB on the secondary cell, and the network device configures a reference cell for the secondary cell, and the terminal device can perform measurement and synchronization based on the SSB of the reference cell, and the terminal device defaults that the reference cell and the current secondary cell are synchronized and co-located, and the terminal device can perform time-frequency synchronization operation of the current secondary cell according to the SSB of the reference cell. SSB-based QCL reference, SSB-based CSI measurement and reporting, SSB-based RLM and BFD / BFR can be supported.

[0077] In network energy saving technology, the network device wants to realize the operation of closing SSB when there is no load on the secondary cell and triggering / activating SSB when there is load on the secondary cell. This SSB that is transmitted when needed and not transmitted 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), for this new type of on-demand transmission of on-demand SSB, it is necessary to support on-demand SSB-based CSI measurement and reporting.

[0078] In the embodiment of the present application, the higher layer signaling can be, for example, radio resource control (RRC) signaling; for example, referred to as RRC message, for example, including MIB, system information, dedicated RRC message; or referred to as RRC IE (RRC information element). The higher layer signaling can also be, for example, MAC (Medium Access Control) signaling; or referred to as MAC CE (MAC control element). But the present application is not limited thereto.

[0079] In the following description, the terms "PDCCH" and "physical downlink control channel" or "downlink control information" can be interchangeable without causing confusion, and the terms "PDSCH" and "physical downlink data channel" or "downlink data" can also be interchangeable. In addition, 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 the present application, the terms "indicate", "activate", and "trigger" can be interchangeable, and can also be used in combination with two or more of them; for example, "indicate / trigger" can be replaced by "activate / deactivate" or "enable / disable", etc.

The network device can configure multiple candidate configuration values, and then indicates / trigger at least one of the multiple candidate configuration values as an available value through MAC CE or RRC signaling or DCI signaling. For example, the network device configures multiple candidate on-demand SSB periodicity values in the on-demand SSB configuration information based on RRC signaling, and then indicates which periodicity is available / valid through MAC CE or RRC signaling or DCI signaling.

[0088] In some embodiments, the first SSB is configured as a periodic always-on SSB or a cell-defined SSB (CD-SSB), and the second SSB is configured as a semi-persistent SSB or an on-demand SSB (OD-SSB). The configuration information and / or indication information are carried in RRC signaling and / or MAC CE and / or DCI.

[0089] In some embodiments, the terminal device is a UE supporting network energy saving (for example, referred to as a Rel-19 NES capable UE), and the present application is not limited thereto. The terminal device in the embodiments of the present application supports OD-SSB secondary cell operation, and can at least receive OD-SSB related configuration, and can also receive OD-SSB transmission indication / trigger / activation / enable information based on RRC and / or MAC CE and / or DCI; the terminal device can perform OD-SSB based measurement and reporting, such as CSI measurement and reporting, and / or BFD / BFR.

[0090] The following first takes the first SSB as an always-on SSB and the second SSB as an on-demand SSB (active OD-SSB) as an example to describe the scenarios supported by the serving cell supporting on-demand SSB secondary cell operation.

[0091] In some embodiments, the on-demand SSB is an SSB triggered by a network device on a secondary cell for Layer 1 / Layer 3 (L1 / L3) measurement; the secondary cell does not transmit SSB before triggering the on-demand SSB, or the secondary cell transmits always-on SSB (such as CD-SSB of the existing protocol); the network device indicates / triggers the on-demand SSB at the moment of sending a secondary cell activation command (RRC or MAC CE based secondary cell activation command), or indicates / triggers the on-demand SSB during the period when the secondary cell is configured but not activated. The indication / triggering of the on-demand SSB signaling can be RRC signaling or MAC CE signaling or DCI signaling.

[0092] FIG. 5 is an example diagram of on-demand SSB triggering according to an embodiment of the present application, showing an example in which there is no always-on SSB, and the cell indicates / triggers the on-demand SSB as needed. As shown in FIG. 5, the network device indicates / triggers the on-demand SSB at the moment of sending a secondary cell activation command, or during the period when the secondary cell is configured but not activated.

[0093] FIG. 6 is another example diagram of on-demand SSB triggering according to an embodiment of the present application, showing an example in which there is always-on SSB. As shown in FIG. 6, the network device can indicate / trigger the on-demand SSB at the moment of sending a secondary cell activation command, or during the period when the secondary cell is configured but not activated; there is always-on SSB before or after triggering the on-demand SSB.

[0094] In some embodiments, the terminal device supports the indication / triggering of the on-demand SSB based on RRC and / or MAC CE or DCI, or the terminal device supports the activation / deactivation, enable / disable of the on-demand SSB based on RRC and / or MAC CE.

[0095] 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, without limitation to the present application.

[0096] 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 enabling / disabling of on-demand SSB and secondary cell (SCell) based on the same RRC and / or MAC CE.

[0097] For example, the activation / deactivation of on-demand SSB is associated with the activation / deactivation of SCell. One MAC CE can be used to activate / deactivate SCell, and at the same time, the MAC CE is also used to activate / deactivate on-demand SSB, and the present application is not limited thereto.

[0098] In some embodiments, the terminal receives / is configured at least one on-demand SSB configuration, wherein the on-demand SSB configuration information at least includes the following:

[0099] the frequency of on-demand SSB;

[0100] the SSB position of on-demand SSB in burst, similar to the parameter of ssb-PositionsInBurst;

[0101] the on-demand SSB periodicity parameter;

[0102] the subcarrier spacing of on-demand SSB;

[0103] the physical cell ID of the serving cell where the on-demand SSB is located;

[0104] the position of on-demand SSB burst, including the time domain position and / or the frequency domain position;

[0105] the downlink transmission power of on-demand SSB; and the like.

[0106] In some embodiments, the terminal device can receive one OD-SSB configuration, and the OD-SSB configuration information contains multiple candidate information of OD-SSB, wherein one candidate information at least includes the OD-SSB periodicity.

[0107] For example, the terminal device receives an OD-SSB configuration, which includes at least a first information list, and the first information list includes P first information or first information IDs, where P represents the maximum number of first information in the first information list, P is a positive integer greater than or equal to 0, for example, P takes a value of 2 or 4, and the first information list takes a value of SEQUENCE (SIZE (1..P)) OF first information / first information ID. Wherein, the first information is the OD-SSB period, or the first information at least contains the OD-SSB period.

[0108] For example, the first information can be the OD-SSB period, and the first information list is the OD-SSB period list. The OD-SSB configuration contains an OD-SSB period list, that is, it contains P candidate OD-SSB period values.

[0109] For another example, the first information at least contains the OD-SSB period, that is, the first information contains at least one parameter, and one of the parameters is the OD-SSB period, such as the first information contains the OD-SSB period parameter and / or the ssbPositionInBusrt parameter. The first information can be named OD-SSB sub-configuration, and the first information list is the OD-SSB sub-configuration list, which contains an OD-SSB sub-configuration list in the OD-SSB configuration, that is, it contains P sub-configurations; one OD-SSB sub-configuration at least contains the OD-SSB period, and the OD-SSB periods in different OD-SSB sub-configurations take different values.

[0110] In some embodiments, the terminal device receives the OD-SSB configuration information configured by the network device, and the OD-SSB configuration includes a first information list, wherein one of the first information in the first information list is set as default or reference, and the default / reference first information of the terminal device is valid / activated / enabled information, and the other first information is deactivated / disabled information.

[0111] In some embodiments, the terminal receives the OD-SSB configuration information configured by the network device, and the OD-SSB configuration includes a first information list, wherein at least one first information in the first information list contains state information, and the state information is used to indicate the state of the first information, that is, the activated / enabled / available / valid state, or the deactivated / disabled / inavailable state.

[0112] The terminal device can also receive MAC CE-based on-demand SSB triggering / indicating information. The MAC CE-based on-demand SSB triggering / indicating information indicates that one of the first information in the first information list is a valid value. For example, the OD-SSB configuration includes an OD-SSB period list, i.e., multiple OD-SSB period candidates, and the MAC CE indicates that one of the OD-SSB period candidates is a valid value. At this time, the OD-SSB transmitted by the serving cell corresponds to the indicated OD-SSB period. If all the first information in the first information list indicated by the MAC CE-based on-demand SSB triggering / indicating information is invalid or 0 or unavailable, it means that the current OD-SSB is deactivated / disabled, and the serving cell does not transmit OD-SSB.

[0113] In some embodiments, the network device sends MAC CE-based OD-SSB triggering / indicating information, and the MAC CE can only implement at most one of the first information in the first information list as a valid value at one time.

[0114] For example, the network device configures one on-demand SSB through RRC, and the on-demand SSB includes a first information list. The first information in the first information list at least includes an OD-SSB period, or the OD-SSB includes an OD-SSB period list. Taking the OD-SSB configuration including an OD-SSB period list as an example, the period list includes OD-SSB period 1 (or period ID = 0, corresponding to a large period) and OD-SSB period 2 (or period ID = 1, corresponding to a small period). During SCell activation, the network device needs to send frequent and dense on-demand SSBs to achieve fast activation of the secondary cell. At this time, the network device sends a MAC CE to the terminal device to indicate / trigger / activate / disable OD-SSB period 2. After the secondary cell is fully activated, the network device only needs to send sparse and large-period on-demand SSBs to achieve measurement. At this time, the network device sends a MAC CE to the terminal device to indicate / trigger / activate / disable OD-SSB period 1.

[0115] In some embodiments, the terminal device receives multiple on-demand SSB configurations configured by the network device, and the terminal device is instructed to indicate / trigger / activate / disable different on-demand SSB configurations to achieve adjustment of the on-demand SSB, for example, through RRC or MAC CE.

[0116] For example, the network device configures 2 on-demand SSBs by RRC, on-demand SSB 1 is configured with a large period, and on-demand SSB 2 is configured with a small period. During SCell activation, the network device needs to send frequent and dense on-demand SSBs to achieve fast activation of the secondary cell, at this time, the network device sends RRC or MAC CE to the terminal device to indicate / trigger / activate / enable on-demand SSB 2, while deactivating / disabling / deactivating on-demand SSB 1. When the secondary cell is fully activated, the network device only needs to send sparse and large-period on-demand SSBs to achieve measurement, at this time, the network device sends RRC or MAC CE to the terminal device to indicate / trigger / activate / enable on-demand SSB 1, while deactivating / disabling / deactivating on-demand SSB 2.

[0117] In some embodiments, the terminal device receives the CD-SSB or always-on SSB configuration information configured by the network device, and also receives the OD-SSB configuration information, some SSB-related characteristics are not included in the OD-SSB configuration information, and the terminal device defaults to the characteristics of the OD-SSB being the same as the CD-SSB, the values of the characteristics of the OD-SSB being the same as the values of the characteristics of the CD-SSB / always-on SSB, and the values of the CD-SSB / always-on SSB can be used, without the need to be included in the OD-SSB configuration. The SSB-related characteristics include SSB transmission power, and / or SSB, etc.

[0118] In some embodiments, the terminal device sends capability reporting information to the network device, the capability reporting information at least indicates that the terminal device can support OD-SSB secondary cell operation, the terminal device can receive the configuration information of the OD-SSB, and the terminal device can perform L1 / L3 measurement and reporting based on the OD-SSB. In addition, the capability reporting information at least indicates the maximum number of second SSB configurations that the terminal device can support / that can be configured, or the maximum number of first information in the first information list in the second SSB configuration; and / or, the terminal device receives capability indication information from the network device, the capability indication information at least indicates the maximum number of second SSB configurations, or the maximum number of first information in the first information list in the second SSB configuration.

[0119] For example, the UE can report the maximum number of on-demand SSBs that can be supported to the base station, and the base station can feed back indication information indicating the maximum number of on-demand SSBs. For another example, the UE can report the maximum number of on-demand SSBs that can be supported to the base station, and the base station can use the maximum number of on-demand SSBs by default. For another example, the base station can directly send indication information indicating the maximum number of on-demand SSBs to the terminal device.

[0120] Herein, the OD-SSB and the on-demand SSB can be interchangeable. The second SSB is an on-demand SSB, and the second SSB configuration is an on-demand SSB configuration.

[0121] In some embodiments, the OD-SSB (configuration) or the second SSB (configuration) can refer to the activated / indicated / triggered OD-SSB (configuration) or the second SSB (configuration). The activated / indicated / triggered OD-SSB (configuration) or the second SSB (configuration) herein can be interpreted as:

[0122] The terminal device receives at least one OD-SSB configuration based on RRC signaling, and receives RRC or MAC CE or DCI signaling for activating / indicating / triggering one of the OD-SSB configurations, which is the activated / indicated / triggered OD-SSB configuration here;

[0123] Alternatively, the terminal device receives one OD-SSB configuration based on RRC signaling, which includes a first information list in the OD-SSB configuration, and the terminal device receives RRC or MAC CE or DCI signaling for activating / indicating / triggering a first information in the first information list, so that the activated / indicated / triggered OD-SSB (configuration) or the second SSB (configuration) can be interpreted / understood as the RRC configured OD-SSB configuration, and the first information is the activated / indicated / triggered first information in the first information list.

[0124] The above illustrates some cases of on-demand SSBs, and the following further illustrates the first configuration information (which can also be referred to as first indication information or other names). The first configuration information is related to the first SSB and / or the second SSB. In the following description, “SSB parameter” refers to, for example, a high-layer parameter related to SSB, such as an RRC parameter related to SSB, and the present application is not limited thereto.

[0125] In some embodiments, the first configuration information at least includes a first index and / or a second index;

[0126] The first index (e.g., SSB-index) is used to indicate a first SSB within a first SSB burst and a second SSB within a second SSB burst, or the first index (SSB-index) is used to indicate a first SSB within a first SSB burst.

[0127] The second index (e.g., OD-SSB-index) is used to indicate a second SSB within a second SSB burst, or is used to indicate a second SSB within an activated / indicated / enabled second SSB burst.

[0128] For example, a terminal device supporting OD-SSB secondary cell operation receives an RRC, which can configure an OD-SSB. An OD-SSB within an OD-SSB burst is indicated by a second index, which is a newly introduced IE, different from a first index (e.g., SSB-Index).

[0129] For example, a first index (e.g., SSB-Index) is used to indicate an SSB index within an SSB (e.g., always-on SSB) burst in an existing protocol, and is also used to indicate an index of an OD-SSB within an OD-SSB burst in embodiments of the present application.

[0130] For another example, a first index (e.g., SSB-Index) is used to indicate an SSB index within an SSB (e.g., always-on SSB) burst in an existing protocol, and a second index is used to indicate an index of an OD-SSB within an OD-SSB burst in embodiments of the present application.

[0131] For still another example, the terminal device further receives second index information, which is used to indicate an index of an OD-SSB within an OD-SSB burst, or is used to indicate an index of an OD-SSB within an activated / indicated / enabled OD-SSB burst. For example, the second index can be OD-SSB-Index.

[0132] In some embodiments, the first configuration information is included in a CSI resource configuration associated with the CSI reporting configuration, and / or the first configuration information is included in a CSI measurement configuration, and / or the first configuration information is included in a CSI associated reporting configuration. The specific content of the CSI reporting configuration (CSI-ReportConfig), the CSI resource configuration (CSI-ResourceConfig), the CSI measurement configuration (CSI-MeasConfig), and the CSI associated reporting configuration (CSI-AssociatedReportConfigInfo) can refer to related technologies.

[0133] The specific locations of the first configuration information are described below.

[0134] First, taking the case that the first configuration information is included in the CSI resource configuration (CSI-ResourceConfig) as an example.

[0135] In some embodiments, the first configuration information at least includes a resource and / or a resource list in the CSI resource configuration; wherein the first configuration information in the CSI resource configuration includes a first resource and / or a first resource list for indicating the first SSB-related parameter, and / or the CSI resource configuration includes a second resource and / or a second resource list for indicating the second SSB-related parameter. For example, the first resource and the first resource list are existing protocol parameters, the first resource is csi-SSB-Resource (SSB resource), and is identified by SSB-Index; and the first resource list is csi-SSB-ResourceList.

[0136] In some embodiments, the first configuration information at least includes a resource set and / or a resource set list in the CSI resource configuration; wherein the first configuration information in the CSI resource configuration includes a first resource set and / or a first resource set list for indicating the first SSB-related parameter, and / or the CSI resource configuration includes a second resource set and / or a second resource set list for indicating the second SSB-related parameter. For example, the first resource set and the first resource set list are existing protocol parameters, the first resource set is csi-SSB-ResourceSet, and the first resource set list is csi-SSB-ResourceSetList.

[0137] In some embodiments, the first configuration information at least includes a resource set ID in the CSI resource configuration; wherein the first configuration information in the CSI resource configuration includes a first resource set ID for indicating the first SSB-related parameter, and / or the CSI resource configuration includes a second resource set ID for indicating the second SSB-related parameter. For example, the first resource set ID is an existing protocol parameter, and is csi-SSB-ResourceSetId.

[0138] For example, the terminal device receives a CSI reporting configuration, the CSI reporting configuration is associated with a CSI resource configuration (CSI-ResourceConfig), the CSI resource configuration (CSI-ResourceConfig) contains at least a second resource set list parameter, the second resource set list parameter contains N second resource sets, where N represents the number of second resource sets in the second resource set list, N is a positive integer greater than or equal to 0, and can take a value of 1 or 2. Each second resource set includes a second resource set ID and a second resource list, and the second resource list includes M second resources, where M represents the maximum number of second resources in each second resource set, and M is a predefined parameter greater than or equal to 0.

[0139] Table 2 schematically shows an example of the first configuration information. As shown in Table 2, the first resource set list is the existing protocol parameter csi-SSB-ResourceSetList, the first resource set ID is CSI-SSB-ResourceSetId, the second resource set list can be named csi-OD-SSB-ResourceSetList, the second resource set ID can be named CSI-OD-SSB-ResourceSetId, and N can be named maxNrofCSI-OD-SSB-ResourceSetsPerConfig.

[0140] In this example, the CSI-SSB-ResourceSetList and the CSI-SSB-ResourceSet in the existing protocol are used to indicate the SSB configuration of the existing protocol, the CD-SSB or the always-on SSB, and the CSI-OD-SSB-ResourceSetList and the CSI-OD-SSB-ResourceSet of the embodiments of the present application are used to indicate the on-demand SSB.

[0141] Table 2

[0142] For another example, the terminal device receives a CSI reporting configuration, the CSI reporting configuration is associated with a CSI resource configuration (CSI-ResourceConfig), the CSI resource configuration (CSI-ResourceConfig) contains at least a second resource set list parameter, the second resource set list parameter contains N first resource sets (csi-SSB-ResourceSet), where N represents the number of first resource sets in the second resource set list, N is a positive integer greater than or equal to 0, and can take a value of 1 or 2. The first resource set is identified by a first resource set ID.

[0143] FIG. 7 is an example diagram of resource sets of an embodiment of the present application. Table 3 also shows an example of the first configuration information. As shown in Table 3, the first resource set list is the existing protocol parameter csi-SSB-ResourceSetList, and the first resource set ID is CSI-SSB-ResourceSetId; the second resource set list is a newly defined parameter, which can be named csi-OD-SSB-ResourceSetList.

[0144] In this example, the CSI-SSB-ResourceSetList in the existing protocol is used to indicate the SSB configuration of the existing protocol, CD-SSB or always-on SSB, and the CSI-OD-SSB-ResourceSetList of the embodiment of the present application is used to indicate the on-demand SSB. The csi-OD-SSB-ResourceSet is used to indicate the SSB configuration of the existing protocol, and can also be used to indicate the on-demand SSB of the embodiment of the present application.

[0145] For example, the csi-SSB-ResourceSetList contains csi-SSB-ResourceSet 0 and csi-SSB-ResourceSet 1, which correspond to the SSB configuration of the existing protocol, CD-SSB or always-on SSB; the csi-OD-SSB-ResourceSetList contains csi-SSB-ResourceSet 2 and csi-SSB-ResourceSet 3, which correspond to the on-demand SSB of the embodiment of the present application.

[0146] Table 3

[0147] For another example, the second resource set is configured to include at least a second resource set ID and / or a second resource list, where the second resource set ID is used to identify a second resource set, and the second resource list includes M first indexes (SSB-indexes) or second indexes (e.g., OD-SSB-Index). M is a positive integer greater than or equal to 0, and M is used to indicate the maximum number of second resources in the second resource set, for example, M = (integer) 64. The second index (e.g., OD-SSB-Index) indicates an OD-SSB index in an OD-SSB burst of an activated / indicated / enabled OD-SSB configuration.

[0148] For another example, the first resource is represented / indicated by using a first index (e.g., SSB-Index), for example, as shown in Table 4, the second resource set is named as CSI-OD-SSB-ResourceSet, the second resource set ID is named as CSI-OD-SSB-ResourceSetId, the second resource list is named as csi-OD-SSB-ResourceList, and M is named as maxNrofCSI-OD-SSB-ResourcePerSet. The second resource list includes M first indexes (e.g., SSB-Index).

[0149] Table 4

[0150] For another example, the second resource is represented / indicated by using a second index (e.g., OD-SSB-Index), for example, as shown in Table 5, the second resource set is named as CSI-OD-SSB-ResourceSet, the second resource set ID is named as CSI-OD-SSB-ResourceSetId, the second resource list is named as csi-OD-SSB-ResourceList, and M is named as maxNrofCSI-OD-SSB-ResourcePerSet. The second resource list includes M second indexes (e.g., OD-SSB-Index).

[0151] Table 5

[0152] For another example, the first configuration information is included in a CSI measurement configuration (CSI-MeaConfig). The CSI measurement configuration (CSI-MeaConfig) is included in a serving cell configuration (ServingCellConfig), and reference can be made to related technologies for the CSI measurement configuration.

[0153] In some embodiments, the first configuration information comprises at least a resource set addition modification list in a CSI measurement configuration; wherein the first configuration information in the CSI measurement configuration comprises a first resource set addition modification list for indicating first SSB related parameters, and / or the first configuration information in the CSI measurement configuration comprises a second resource set addition modification list for indicating second SSB related parameters.

[0154] In some embodiments, the first configuration information comprises at least a resource set release list in a CSI measurement configuration; wherein the first configuration information in the CSI measurement configuration comprises a first resource set release list for indicating first SSB related parameters, and / or the first configuration information in the CSI measurement configuration comprises a second resource set release list for indicating second SSB related parameters.

[0155] For example, a terminal device receives (is configured with) a CSI measurement configuration (CSI-MeasConfig) comprising a resource set addition modification list (ResourceSetToAddModList) and / or a resource set release list (ResourceSetToReleaseList). The resource set addition modification list is used to indicate a pool of one resource set referenced / acquired from a CSI resource configuration, containing at most N resource sets; the resource set release list indicates at most N resource sets.

[0156] Table 6 schematically shows a case where the first configuration information is comprised in a CSI measurement configuration. As shown in Table 6, the first configuration information in the CSI measurement configuration can comprise a first resource set addition modification list (csi-SSB-ResourceSetToAddModList) and / or a first resource set release list (csi-SSB-ResourceSetToReleaseList), and / or the CSI measurement configuration can comprise a second resource set addition modification list (such as a parameter named csi-OD-SSB-ResourceSetToAddModList) and / or a second resource set release list (such as a parameter named csi-OD-SSB-ResourceSetToReleaseList).

[0157] Table 6

[0158] For example, the first configuration information is included in a CSI aperiodic trigger list and / or CSI associated reporting configuration information (CSI-AssociatedReportConfigInfo). For example, the CSI aperiodic trigger list includes the CSI associated reporting configuration information (CSI-AssociatedReportConfigInfo). For the CSI associated reporting configuration information, refer to related technologies.

[0159] In some embodiments, the first configuration information at least includes resources and / or resource sets in the CSI associated reporting configuration; wherein the first configuration information in the CSI associated reporting configuration includes a first resource and / or a first resource set for indicating a first SSB related parameter, and / or the CSI associated reporting configuration includes a second resource and / or a second resource set for indicating a second SSB related parameter.

[0160] For example, the terminal device is configured with a CSI aperiodic trigger list, and the CSI aperiodic trigger list includes at least one CSI-AssociatedReportConfigInfo. The CSI-AssociatedReportConfigInfo can include a second resource set for indicating an OD-SSB resource configuration of the CSI associated reporting configuration. The second resource set takes a value of a number or a sequence number of the second resource set, and the number is greater than 0 and less than N.

[0161] Table 7 schematically shows a case where the first configuration information is included in the CSI associated reporting configuration. As shown in Table 7, the second resource set can be named as CSI-OD-SSB-ResourceSet, and N is maxNrofCSI-OD-SSB-ResourceSets PerConfig.

[0162] Table 7

[0163] For example, the first configuration information at least includes a resource type in the CSI resource configuration.

[0164] In some embodiments, the first configuration information at least includes a resource type in the CSI resource configuration; wherein the first configuration information in the CSI resource configuration includes a first resource type for indicating a first SSB related parameter, and / or a second resource type for indicating a second SSB related parameter.

[0165] For example, the terminal device receives a CSI reporting configuration, the CSI reporting configuration is associated with a CSI resource configuration (CSI-ResourceConfig), the CSI resource configuration contains at least second resource type information, the second resource type information is used to indicate the time domain behavior (periodic or semi-persistent or aperiodic) of the second resource configuration, and the second resource configuration contains a second resource, and / or a second resource list, and / or a second resource set, and / or a second resource set list.

[0166] For another example, the first resource type is resourceType contained in the CSI resource configuration CSI-ResourceConfig in the existing protocol, the resourceType is used to indicate the time domain characteristics of the resource configuration other than csi-SSB-ResourceSetList, that is, to indicate the time domain type of nzp-CSI-RS-ResourceSet and csi-IM-ResourceSet. The second resource type is different from the first resource type, and is used to indicate the time domain characteristics of the OD-SSB resource, that is, to indicate the time domain characteristics of the second resource set list and / or the second resource set and / or the second resource. The second resource type is optional, and the value can be periodic or semi-persistent or aperiodic.

[0167] For example, the terminal device receives a CSI resource configuration, if the CSI resource configuration contains a second resource type, the terminal device determines that the CSI reporting configuration is associated with the OD-SSB resource, the terminal device measures and reports the OD-SSB, otherwise, the terminal device determines that the CSI reporting configuration is not associated with the OD-SSB.

[0168] Table 8 schematically shows the case where the first configuration information is the resource type. As shown in Table 8, for example, the second resource type can be named od-ssb-resourceType.

[0169] Table 8

[0170] In some embodiments, the value of the second resource type is periodic, the transmission of the second SSB is indicated based on RRC signaling; or the value of the second resource type is semi-persistent, the transmission of the second SSB is indicated based on RRC signaling and / or MAC CE.

[0171] For example, the value of the second resource type is periodic, indicating that the second resource and / or the second resource set and / or the second resource set list is periodic, and the network device can only indicate the OD-SSB transmission based on RRC, that is, the terminal device determines the start and end of the OD-SSB based on RRC, and the terminal device does not expect MAC CE to indicate the OD-SSB transmission.

[0172] For another example, the second resource type is set as semi-persistent, indicating that the second resource and / or the second resource set and / or the second resource set list is semi-persistent, and the network device can indicate the OD-SSB transmission based on RRC and / or MAC CE, i.e., the terminal device can determine the transmission of the OD-SSB based on RRC or MAC CE signaling.

[0173] In some embodiments, the terminal device does not expect the periodic CSI reporting configuration to be associated with the semi-persistent or aperiodic second SSB configuration, or the periodic CSI reporting configuration to be associated with the second SSB configuration indicated based on RRC, or the terminal device does not expect the periodic CSI reporting configuration to be associated with the second SSB configuration indicated based on MAC CE.

[0174] For another example, the first configuration information is included in the CSI reporting configuration (CSI-ReportConfig).

[0175] In some embodiments, the first configuration information is an SSB feedback quantity in the CSI reporting configuration; wherein the CSI reporting configuration includes a first SSB feedback quantity for indicating first SSB related parameters, and / or the CSI reporting configuration includes a second SSB feedback quantity for indicating second SSB related parameters.

[0176] For example, the terminal device receives / configures a CSI reporting configuration (CSI-ReportConfig) containing a high layer parameter reportQuantity, which can be set as a first SSB feedback quantity and / or a second SSB feedback quantity.

[0177] For example, the first SSB feedback quantity (reportQuantity) contains ssb-Index-SINR / RSRP and ssb-Index-RSRP / SINR-Index, which are used for beam management related measurement and reporting. The second SSB configuration is the OD-SSB configuration in the embodiments of the present application, or the OD-SSB configuration (such as OD-SSB periodic configuration) indicated / activated / enabled, and the second SSB feedback quantity is a feedback quantity related to the second SSB, i.e., the feedback quantity at least contains a second SSB resource indication and / or a second SSB resource index, for example, the second SSB feedback quantity can be od-ssb-Index-SINR / RSRP, od-ssb-Index-RSRP / SINR-Index.

[0178] For example, the terminal device receives a CSI reporting configuration, and the reportQuantity in the CSI reporting configuration is set to a first SSB feedback quantity, and the terminal device determines that the CSI measurement and reporting are based on OD-SSB measurement and reporting.

[0179] In some embodiments, the first configuration information is one or more parameters in the CSI reporting configuration and / or in the CSI resource configuration, and the one or more parameters are used to indicate whether the CSI reporting configuration is related to the second SSB, and / or are used to indicate that the CSI resource is an OD-SSB resource, and / or the CSI resource at least includes the OD-SSB resource.

[0180] For example, the terminal device receives / configures a CSI reporting configuration (CSI-ReportConfig), and the CSI reporting configuration includes a first OD-SSB parameter, and the first OD-SSB parameter is used to indicate whether the CSI reporting configuration is related to OD-SSB, and / or is used to indicate that the CSI resource is an OD-SSB resource, and / or the CSI resource at least includes the OD-SSB resource, and the terminal device determines whether to perform measurement and reporting based on OD-SSB based on the first OD-SSB parameter.

[0181] For another example, the terminal device receives / configures a CSI reporting configuration (CSI-ReportConfig), and the CSI reporting configuration is associated with a CSI resource configuration, and the CSI resource configuration includes a first OD-SSB parameter, and the first OD-SSB parameter is used to indicate whether the CSI reporting configuration is related to OD-SSB, and / or is used to indicate that the CSI resource is an OD-SSB resource, and / or the CSI resource at least includes the OD-SSB resource, and the terminal device determines whether to perform measurement and reporting based on OD-SSB based on the first OD-SSB parameter.

[0182] For another example, when the first OD-SSB parameter takes a certain value (such as enable, true, or 1) or the first OD-SSB parameter is present, it indicates that the CSI reporting configuration is related to OD-SSB, and the terminal device performs measurement and reporting based on OD-SSB; when the first OD-SSB parameter takes another value (such as diable, false, or 0) or the first OD-SSB parameter is absent, it indicates that the CSI reporting configuration is not related to OD-SSB.

[0183] For example, the terminal device receives / is configured a CSI reporting configuration (CSI-ReportConfig), the CSI reporting configuration includes a first OD-SSB parameter in a parameter CSI-SSB-ResourceSet in a CSI resource configuration associated with the CSI reporting configuration, the parameter is used to indicate whether the CSI-SSB-ResourceSet is related to the OD-SSB, is used to indicate whether the CSI-SSB-ResourceSet represents the SSB resource (always-on SSB or CD-SSB) in the existing protocol, or represents the OD-SSB resource in the embodiment of the present application, or represents both the SSB resource (always-on SSB or CD-SSB) in the existing protocol and the OD-SSB resource in the embodiment of the present application. When the first OD-SSB parameter takes a certain value (for example, enable, true, or 1) or the first OD-SSB parameter appears, it indicates that the CSI-SSB-ResourceSet contains the OD-SSB resource in the embodiment of the present application (the CSI-SSB-ResourceSet is the OD-SSB resource in the embodiment of the present application, or the CSI-SSB-ResourceSet is the SSB resource in the existing protocol and the OD-SSB resource in the embodiment of the present application); when the first OD-SSB parameter takes another value (for example, diable, false, or 0) or the first OD-SSB parameter is absent, it indicates that the CSI-SSB-ResourceSet is the SSB resource in the existing protocol.

[0184] FIG. 8 is an example diagram of a resource set in the embodiment of the present application. As shown in FIG. 8, the first OD-SSB parameter is named as On-demand SSB indicator, which is used to indicate whether the csi-SSB-ResourceSet contains the On-demand SSB resource. Table 9 schematically shows the case where the first configuration information is an indicator.

[0185] Table 9

[0186] In some embodiments, the terminal device reports the CSI to the network device. The first SSB resource indication / index in the CSI is related to the first SSB, and / or the second SSB resource indication / index in the CSI is related to the second SSB.

[0187] For example, the terminal device reports CSI, wherein the CSI can include CQI, PMI, CRI, SSBRI, LI, RI, L1-RSRP, L1-SINR, and / or a first SSB resource indicator / index or a second SSB resource indicator / index.

[0188] For another example, the second SSB can be an OD-SSB or an indicated / activated / enabled OD-SSB configuration (for example, an OD-SSB periodic configuration); and the second SSB resource indicator / index is a resource index number of a second SSB in a set of second SSB resources or a second SSB resource set.

[0189] For yet another example, the first SSB resource indicator / index K (K >= 0) corresponds to a (k+1)th entity configured in a first SSB resource list (csi-SSB-ResourceList) included in a CSI-SSB-ResourceSet; and the second SSB resource indicator / index K (K >= 0) corresponds to a (k+1)th entity configured in a second SSB resource list (csi-OD-SSB-ResourceList) included in a CSI-OD-SSB-ResourceSet.

[0190] For still another example, the terminal device receives CSI reporting configuration information (CSI-ReportConfig), generates a CSI report and reports the CSI report to the network device, wherein the CSI report includes CSI-related L1, L1-RSRP / SINR, CRI, SSBRI or a second SSB resource indicator / index. If the terminal device is configured with a CSI reporting configuration (CSI-ReportConfig), and a high-level parameter reportQuantity in the CSI reporting configuration is set to a second SSB feedback quantity, the CSI report reported by the terminal device at least includes a second SSB resource indicator / index, or the terminal device reports a second SSB resource indicator / index.
