Description

Data sending method, receiving method, device and communication system Technical Field

[0001] The embodiments of the present application relate to the field of wireless communication technologies. Background Art

[0002] A large number of NR (New Radio) base stations have been deployed in the 5th Generation Mobile Communication Technology (5G) networks standardized by the 3rd Generation Partnership Project (3GPP). NR base stations require large bandwidths (e.g., 100MHz), a large number of ports (64T / 64R), and shorter time intervals (TTIs) (1ms). Consequently, NR base stations consume significantly more energy than LTE base stations for functions such as baseband processing and digital front-ends.

[0003] According to operator statistics, the average energy consumption of an NR base station is more than three times that of an LTE base station. Nearly half of the cost of deploying 5G networks by operators is electricity expenses. More importantly, even in periods of no business, the energy consumption of NR base stations is still very high, because even when there is no business, NR base stations still need to send public signals, such as synchronization signal blocks (SSB), system information blocks (SIB, such as SIB1) and system information (SI), which greatly reduces the energy efficiency of NR base stations. Energy saving in NR networks is an urgent problem to be solved. In addition, in future networks (such as 6G or later networks), the problem of network energy saving also needs to be solved.

[0004] It should be noted that the above introduction to the technical background is merely intended to provide a clear and complete description of the technical solutions of this application and facilitate understanding by those skilled in the art. Simply because these solutions are described in the background technology section of this application, it should not be assumed that the above technical solutions are well known to those skilled in the art.

[0005] Summary of the Invention

[0006] The inventors discovered that a cell configured as a secondary cell (SCell) of a terminal equipment (UE) or the base station where the SCell is located can decide whether to send SSBs according to demand, that is, the SCell can use on-demand SSB transmission to save network energy or power consumption. The network device can configure an SCell with on-demand SSB transmission to the UE or configure which SCells have on-demand SSB. However, if the network device does not know whether the UE supports SCell operation with on-demand SSB, the network configuration of the UE may be inconsistent with the UE's capabilities, resulting in incorrect configuration or invalid configuration. Therefore, the network needs to know whether the UE supports SCell operation with on-demand SSB, but currently there is no solution for how the network knows whether the UE supports SCell operation with on-demand SSB.

[0007] Furthermore, for SCells that have or support on-demand SSBs, the SSBs enable the UE to detect or measure the SCell. If the SCell does not transmit an SSB, but the UE continues to perform SSB reception-related procedures, this may result in inaccurate detection or measurement results for the SCell. The UE may even initiate a corresponding failure procedure due to the lack of SSB reception, occupying radio resources and increasing UE power consumption. Therefore, whether and how the UE needs to know whether an SCell is currently transmitting (on-demand) SSBs is a question that requires further discussion.

[0008] Furthermore, if the UE does not know which SCell supports on-demand SSB transmission, it cannot perform the corresponding operation, which may cause the UE to fail time and frequency synchronization with the SCell or inaccurate measurement results. Therefore, whether and how the UE knows which SCell supports on-demand SSB transmission is also an issue that needs to be addressed.

[0080] FIG1 is a schematic diagram of a communication system according to an embodiment of the present application, schematically illustrating a situation using a terminal device and a network device as an example. As shown in FIG1 , a communication system 100 may include a network device 101 and terminal devices 102 and 103. For simplicity, FIG1 illustrates only two terminal devices and one network device as an example, but the embodiments of the present application are not limited thereto.

[0081] In the embodiment of the present application, existing services or future services can be transmitted between the network device 101 and the terminal devices 102 and 103. For example, these services may include, but are not limited to, enhanced mobile broadband (eMBB), massive machine type communication (mMTC), ultra-reliable and low-latency communication (URLLC), and related communications of terminal devices with reduced capabilities, etc.

[0083] In 3GPP Rel-15 / 16, in the scenario of intra-band carrier aggregation (CA), the secondary cell (SCell) of the UE may not send SSB. The secondary cell is called an SSB-less SCell. The timing reference of the SSB-less SCell comes from a special cell (SpCell) or other SCells in the same frequency band as the SSB-less SCell.

[0084] In 3GPP Rel-18, it was agreed that for SSB-less SCells with inter-band CA, the network configures the serving cell index (ServCellIndex) of its reference cell, which is included in the FrequencyInfoDL IE of the SSB-less SCell. The reference cell provides the timing reference and automatic gain control (AGC) source for the SSB-less SCell. If the reference cell is an SCell or a primary secondary cell (PSCell), it should be an activated SCell or an activated PSCell.

[0085] One of the goals in 3GPP Rel-19 is to specify procedures and signaling methods for supporting SCell operation with on-demand synchronization signal blocks (SSBs) for UEs in connected mode configured with CA, for both intra-band and inter-band CA. The triggering method is selected from UE uplink wake-up signals using existing signals / channels, cell on / off indications via backhaul, and cell activation / deactivation signaling. The on-demand SSB transmission can be used by the UE for at least time-frequency synchronization of the SCell, layer 1 or layer 3 measurements (L1 / L3 measurements), and SCell activation. The standard is shown in Table 1 below:

[0086] Table 1

[0087] The following describes the method in combination with various embodiments.

[0088] Embodiments of the first aspect

[0089] An embodiment of the present application provides a data sending method, which is described from the perspective of a terminal device.

[0090] FIG2 is a schematic diagram of a data transmission method according to an embodiment of the present application. The method is applied to a terminal device. As shown in FIG2 , the method includes:

[0091] 201. The terminal device sends first indication information to the network device, where the first indication information is used to indicate that the terminal device supports the secondary cell operation of the on-demand synchronization signal block, or that the terminal device does not support the secondary cell operation of the on-demand synchronization signal block.

[0092] According to the above embodiment, the terminal device can send indication information to the network device, indicating that the terminal device supports or does not support the secondary cell operation of the on-demand synchronization signal block. Thereby, the network device can know the UE capabilities and help the network device determine whether to configure the UE with a secondary cell with on-demand synchronization signal block transmission or which secondary cells with on-demand synchronization signal block transmission to configure, thereby enabling the network device to perform configuration consistent with the UE capabilities, avoiding incorrect configuration or invalid configuration caused by inconsistency between the network configuration and the UE capabilities, and solving one of the above-mentioned problems existing in the prior art.

[0093] It is worth noting that FIG2 above is merely a schematic illustration of an embodiment of the present application, and the present application is not limited thereto. For example, the execution order of the various operations may be appropriately adjusted, and other operations may be added or some operations may be reduced. Those skilled in the art may make appropriate modifications based on the above description, and are not limited to the description of FIG2 above.

[0094] In some embodiments, the first indication information is included in a UE capability information message, an RRC Setup Request message, an RRC Setup Complete message, an RRC Reconfiguration Complete message, or a UE Assistance Information message. For example, the terminal device may proactively send the first indication information to the network device, or may send the first indication information after receiving a request from the network device.

[0095] In some embodiments, the network device may preconfigure a first table or predefine the first table, wherein the first table includes a correspondence between first indication information and UE capability information indicating whether the UE supports secondary cell operation of an on-demand synchronization signal block. The first indication information may be a row index of the first table or an index of the capability information, or the first indication information may be a value corresponding to the UE capability in the first table. After receiving the first indication information, the network device may determine the UE capability indicated by the first indication information by looking up the table.

[0096] In some embodiments, when the first indication information is included in the RRC connection request message, the size of the first indication information does not exceed a preset value, which is configured or predefined by the network device, for example, 1 bit.

[0097] In some embodiments, different values ​​of the first indication information are used to indicate whether the terminal device supports the SCell operation of on-demand SSB. For example, the first indication information is 1 bit, and different values ​​of the 1 bit are used to indicate whether the terminal device supports the SCell operation of on-demand SSB. For example, if the value of the 1 bit is 1, it indicates that the terminal device supports the secondary cell operation of the on-demand synchronization signal block, and if the value of the 1 bit is 0, it indicates that the terminal device does not support the secondary cell operation of the on-demand synchronization signal block; or, if the value of the 1 bit is 0, it indicates that the terminal device supports the secondary cell operation of the on-demand synchronization signal block, and if the value of the 1 bit is 1, it indicates that the terminal device does not support the secondary cell operation of the on-demand synchronization signal block.

[0098] In some embodiments, whether the first indication information appears indicates whether the terminal device supports SCell operation of on-demand SSB. For example, the first indication information is 1 bit, and the presence of the 1 bit indicates that the terminal device supports the secondary cell operation of the on-demand synchronization signal block, and the absence of the 1 bit indicates that the terminal device does not support the secondary cell operation of the on-demand synchronization signal block; or, the value of the 1 bit is 1 or 0, indicating that the terminal device supports the secondary cell operation of the on-demand synchronization signal block, and the value of the 1 bit is empty, indicating that the terminal device does not support the secondary cell operation of the on-demand synchronization signal block.

[0099] In some embodiments, the first indication information is used to indicate that the terminal device supports the secondary cell operation of the on-demand synchronization signal block or does not support the secondary cell operation of the on-demand synchronization signal block. In this case, the first indication information can be represented by the above 1 bit.

[0100] In some embodiments, the first indication information is used to indicate that the terminal device supports secondary cell operation of on-demand synchronization signal blocks or does not support secondary cell operation of on-demand synchronization signal blocks in at least one of the following carrier aggregation modes:

[0101] Intra-band carrier aggregation (intra-band CA);

[0102] Inter-band carrier aggregation (inter-band CA);

[0103] Intra-band co-located CA;

[0104] Intra-band non co-located CA;

[0105] Carrier aggregation within frequency range 1 (FR1);

[0106] Frequency Range 2 (FR2) intra-carrier aggregation;

[0107] FR1 and FR2 carrier aggregation.

[0108] Therefore, the terminal device indicates to the network device whether it supports or does not support the secondary cell operation of the on-demand synchronization signal block according to different carrier aggregation modes, which can help the network device determine whether to configure the UE with a secondary cell with on-demand synchronization signal block transmission or which secondary cells with on-demand synchronization signal block transmission to configure, so as to avoid incorrect configuration or invalid configuration caused by inconsistency between network configuration and UE capabilities.

[0109] The above-mentioned frequency range 1 is also called the sub-6GHz frequency range, including the 410MHz-7125MHz frequency range; frequency range 2 can be the frequency range above 6GHz, currently including 2 sub-frequency ranges FR2-1 and FR2-2, the FR2-1 frequency range is 24.25GHz-52.6GHz, and the FR2-2 frequency range is 52.6GHz-71GHz.

[0110] In some embodiments, the first indication information is used to indicate whether the terminal device supports or does not support the secondary cell operation of the on-demand synchronization signal block in a carrier aggregation mode. The first indication information is, for example, 1 bit. Taking the carrier aggregation mode as the same-band carrier aggregation as an example, when the value of this bit is 1, it indicates that the terminal device supports the secondary cell operation of the on-demand synchronization signal block under the same-band carrier aggregation, and the value of this bit is 0, it indicates that the terminal device does not support the secondary cell operation of the on-demand synchronization signal block under the same-band carrier aggregation; or, the value of this bit is 0, it indicates that the terminal device supports the secondary cell operation of the on-demand synchronization signal block under the same-band carrier aggregation, and the value of this bit is 1, it indicates that the terminal device does not support the secondary cell operation of the on-demand synchronization signal block under the same-band carrier aggregation; or, the appearance of this bit indicates that the terminal device supports the secondary cell operation of the on-demand synchronization signal block under the same-band carrier aggregation, and the absence of this bit indicates that the terminal device does not support the secondary cell operation of the on-demand synchronization signal block under the same-band carrier aggregation; or, the value of this bit is 1 or 0, it indicates that the terminal device supports the secondary cell operation of the on-demand synchronization signal block under the same-band carrier aggregation, and the value of this bit is empty, it indicates that the terminal device does not support the secondary cell operation of the on-demand synchronization signal block under the same-band carrier aggregation. The case where the first indication information of 1 bit is used to indicate that the terminal device supports or does not support the secondary cell operation of the on-demand synchronization signal block in other carrier aggregation modes is similar and will not be repeated here.

[0111] In some embodiments, the terminal device uses respective first indication information for the at least one carrier aggregation mode, that is, uses different first indication information for different carrier aggregation modes.

[0112] In some embodiments, the first indication information is used to indicate whether the terminal device supports or does not support the secondary cell operation of the on-demand synchronization signal block in a carrier aggregation mode, and the carrier aggregation mode is configured by the network or pre-defined by the terminal device.

[0113] In some embodiments, the first indication information is used to indicate that the terminal device supports or does not support the secondary cell operation of the on-demand synchronization signal block for more than one carrier aggregation mode. For example, the first indication information is a bitmap, and the length of the bitmap can be, for example, less than or equal to 8 bits, wherein each bit in the bitmap indicates whether the terminal device supports or does not support the secondary cell operation of the on-demand synchronization signal block for one of the above-mentioned more than one carrier aggregation modes. For example, taking the first indication information as an example of whether the terminal device supports the secondary cell operation of the on-demand synchronization signal block in the same-band carrier aggregation mode and the different-band carrier aggregation mode, a bit in the bitmap with a value of 1 indicates support for the secondary cell operation of the on-demand synchronization signal block, and a bit with a value of 0 indicates non-support for the secondary cell operation of the on-demand synchronization signal block, when the first indication information is "11", it indicates that the terminal device supports the secondary cell operation of the on-demand synchronization signal block in both the same-band carrier aggregation mode and the different-band carrier aggregation mode, and when the first indication information is "00", it indicates that the terminal device The device does not support the secondary cell operation of the on-demand synchronization signal block in both the same-band carrier aggregation mode and the different-band carrier aggregation mode. When the first indication information is "10", it means that the terminal device supports the secondary cell operation of the on-demand synchronization signal block in the same-band carrier aggregation mode, but does not support the secondary cell operation of the on-demand synchronization signal block in the different-band carrier aggregation mode. When the first indication information is "01", it means that the terminal device does not support the secondary cell operation of the on-demand synchronization signal block in the same-band carrier aggregation mode, but supports the secondary cell operation of the on-demand synchronization signal block in the different-band carrier aggregation mode.

[0114] In some embodiments, the first indication information is used to indicate whether the terminal device supports or does not support the secondary cell operation of the on-demand synchronization signal block in more than one carrier aggregation mode. The more than one carrier aggregation mode and the order of the bits corresponding to the more than one carrier aggregation mode in the first indication information are configured by the network or pre-defined by the terminal device.

[0115] In some embodiments, different values ​​of the first indication information may indicate that the terminal device supports or does not support the secondary cell operation of the on-demand synchronization signal block for more than one carrier aggregation mode. For example, the first indication information may be 3 bits, with a value from 0 to 7, wherein when the value of the first indication information is 0, it indicates that the secondary cell operation of the on-demand synchronization signal block is not supported for the above-mentioned carrier aggregation mode; when the value of the first indication information is 1, it indicates that the secondary cell operation of the on-demand synchronization signal block is supported for the same-frequency band aggregation mode; when the value of the first indication information is 2, it indicates that the secondary cell operation of the on-demand synchronization signal block is supported for the different-frequency band aggregation mode; when the value of the first indication information is 3, it indicates that the secondary cell operation of the on-demand synchronization signal block is supported for the same-frequency band co-location carrier aggregation mode, and so on.

[0116] In some embodiments, the first indication information is used to indicate to the terminal device whether to support or not support the secondary cell operation of the on-demand synchronization signal block in one or more frequency bands or frequency band combinations supported by carrier aggregation.

[0117] Therefore, the terminal device indicates to the network device whether it supports or does not support the secondary cell operation of the on-demand synchronization signal block according to different frequency bands or frequency band combinations, which can help the network device determine whether to configure the UE with a secondary cell with on-demand synchronization signal block transmission or which secondary cells with on-demand synchronization signal block transmission to configure, so as to avoid incorrect configuration or invalid configuration caused by inconsistency between the network configuration and the UE capabilities.

[0118] In some embodiments, the first indication information indicates to the terminal device whether to support or not support the secondary cell operation of the on-demand synchronization signal block in a frequency band or frequency band combination supported by carrier aggregation. For example, the first indication information is 1 bit. The relationship between the value of the 1 bit and whether the terminal device supports or does not support the secondary cell operation of the on-demand synchronization signal block in the frequency band or frequency band combination can be found in the previous text and will not be repeated here.

[0119] In some embodiments, when the first indication information indicates to the terminal device whether a frequency band or frequency band combination supported by carrier aggregation supports or does not support the secondary cell operation of the on-demand synchronization signal block, the frequency band or frequency band combination is configured by the network or pre-defined by the terminal device.

[0120] In some embodiments, the terminal device uses respective first indication information for a frequency band or a frequency band combination supported by carrier aggregation, that is, uses different first indication information for different frequency bands or frequency band combinations.

[0121] In some embodiments, the first indication information indicates to the terminal device whether it supports or does not support the secondary cell operation of the on-demand synchronization signal block for each frequency band (band) or frequency band combination (band combination) supported by the carrier aggregation. For example, the terminal device can indicate the first indication information for each frequency band or frequency band combination respectively, and the first indication information can be 1 bit. Alternatively, the first indication information is a bitmap, and each bit in the bitmap indicates whether the terminal device supports or does not support the secondary cell operation of the on-demand synchronization signal block in a frequency band or frequency band combination supported by the carrier aggregation. The relationship between the value of each bit in the bitmap and the support or non-support of the secondary cell operation of the on-demand synchronization signal block by the terminal device in the corresponding frequency band or frequency band combination can be found in the previous text and will not be repeated here.

[0122] In some embodiments, when the first indication information indicates to the terminal device whether it supports or does not support the secondary cell operation of the on-demand synchronization signal block in more than one frequency band or frequency band combination supported by carrier aggregation, the more than one frequency band or frequency band combination and the order of the bits corresponding to the more than one frequency band or frequency band combination in the first indication information are configured by the network or pre-defined by the terminal device.

[0123] In some embodiments, different values ​​of the first indication information may indicate that the terminal device supports or does not support the secondary cell operation of the on-demand synchronization signal block in more than one frequency band or frequency band combination supported by the carrier aggregation. For example, the first indication information may be 3 bits with a value from 0 to 7, wherein when the value of the first indication information is 0, it indicates that the terminal device does not support the secondary cell operation of the on-demand synchronization signal block in the above-mentioned more than one frequency band or frequency band combination of the carrier aggregation; when the value of the first indication information is 1, it indicates that the terminal device supports the secondary cell operation of the on-demand synchronization signal block in the first frequency band or frequency band combination of the carrier aggregation; when the value of the first indication information is 2, it indicates that the terminal device supports the secondary cell operation of the on-demand synchronization signal block in the second frequency band or frequency band combination of the carrier aggregation; when the value of the first indication information is 3, it indicates that the terminal device supports the secondary cell operation of the on-demand synchronization signal block in the third frequency band or frequency band combination of the carrier aggregation, and so on.

[0124] It can be seen from the above embodiments that in the data sending method of the embodiments of the present application, the terminal device can send indication information to the network device, indicating that the terminal device supports or does not support the secondary cell operation of the on-demand synchronization signal block. Thereby, the network device can know the UE capabilities and help the network device determine whether to configure the UE with a secondary cell with on-demand synchronization signal block transmission or which secondary cells with on-demand synchronization signal block transmission to configure, thereby enabling the network device to perform configuration consistent with the UE capabilities, avoiding incorrect configuration or invalid configuration caused by inconsistency between the network configuration and the UE capabilities, and solving one of the above-mentioned problems existing in the prior art.

[0125] The above embodiments are merely exemplary of the present invention, but the present invention is not limited thereto. Appropriate modifications may be made based on the above embodiments. For example, the above embodiments may be used alone, or one or more of the above embodiments may be combined.

[0126] It is worth noting that the above only describes the steps related to the present application, but the present application is not limited thereto. The data receiving method of the present application may also include other steps, and for the specific content of these steps, reference may be made to the relevant art.

[0127] The above embodiments are merely exemplary of the present invention, but the present invention is not limited thereto. Appropriate modifications may be made based on the above embodiments. For example, the above embodiments may be used alone, or one or more of the above embodiments may be combined.

[0128] Embodiments of the second aspect

[0129] An embodiment of the present application provides a data receiving method, which is described from the perspective of a terminal device.

[0130] FIG3 is a schematic diagram of a data receiving method according to an embodiment of the present application. The method is applied to a terminal device. As shown in FIG3 , the method includes:

[0131] 301. The terminal device receives second indication information sent by the network device, where the second indication information is used to indicate whether the secondary cell (SCell) is sending relevant information of the synchronization signal block (SSB) and / or whether the terminal device needs to receive, detect or measure the synchronization signal block in the secondary cell.

[0132] According to the above embodiment, the terminal device receives relevant information sent by the network device indicating whether the secondary cell is sending a synchronization signal block (SSB) and / or indication information of whether the terminal device needs to receive, detect or measure the synchronization signal block in the secondary cell. As a result, the terminal device can perform processes related to SSB reception when the SCell sends the SSB, which is beneficial to saving power of the terminal device, while avoiding inaccurate detection results or measurement results of the SCell by the terminal device, and avoiding the UE initiating a corresponding failure process due to failure to receive the SSB, thereby reducing the waste of wireless resources and solving one of the above problems existing in the prior art.

[0133] It is worth noting that FIG3 above merely illustrates an embodiment of the present application, and the present application is not limited thereto. For example, the execution order of the various operations may be appropriately adjusted, and other operations may be added or some operations may be removed. Those skilled in the art may make appropriate modifications based on the above description, and are not limited to the description in FIG3 above.

[0134] In some embodiments, the second indication information is carried by RRC signaling.

[0135] In some embodiments, when the second indication information is carried by RRC signaling, the second indication information is included in the configuration of the secondary cell added or modified by the network device for the terminal device; or, the second indication information is included in the measurement configuration configured by the network device for the terminal device, and the measurement configuration is, for example, the configuration of the frequency of the SSB of the secondary cell whose measurement object is the secondary cell.

[0136] In some embodiments, the second indication information is included in downlink control information (DCI) or a medium access control element (MAC Control Element, MAC CE).

[0137] In some embodiments, the second indication information is used to indicate whether one or more secondary cells are sending relevant information of a synchronization signal block (SSB), and / or whether the terminal device needs to receive, detect or measure a synchronization signal block in a secondary cell.

[0138] In some embodiments, different values ​​of the second indication information indicate whether a SCell is currently sending an SSB or whether the UE needs to receive, detect, or measure the SSB in a SCell. For example, the second indication information is 1 bit, and different values ​​of the 1 bit indicate whether a SCell is currently sending an SSB or whether the UE needs to receive, detect, or measure the SSB in a SCell. For example, if the value of the 1 bit is 1, it indicates that the SCell is currently sending an SSB or the terminal device needs to receive, detect, or measure the SSB in a SCell, and if the value of the 1 bit is 0, it indicates that the SCell is not currently sending an SSB or the terminal device does not need to receive, detect, or measure the SSB in a SCell; or, if the value of the 1 bit is 0, it indicates that the SCell is currently sending an SSB or the terminal device needs to receive, detect, or measure the SSB in a SCell, and if the value of the 1 bit is 1, it indicates that the SCell is not currently sending an SSB or the terminal device does not need to receive, detect, or measure the SSB in a SCell.

[0139] In some embodiments, whether the second indication information appears indicates whether an SCell is currently sending an SSB or whether the UE needs to receive, detect, or measure the SSB in an SCell. For example, the presence of this bit indicates that the SCell is currently sending an SSB or the terminal device needs to receive, detect, or measure the SSB in an SCell, and the absence of this bit indicates that the SCell is not currently sending an SSB or the terminal device does not need to receive, detect, or measure the SSB in an SCell; or, the value of this bit is 1 or 0, indicating that the SCell is currently sending an SSB or the terminal device needs to receive, detect, or measure the SSB in an SCell, and the value of this bit is empty, indicating that the SCell is not currently sending an SSB or the terminal device does not need to receive, detect, or measure the SSB in an SCell.

[0140] In some embodiments, the second indication information is used to indicate whether a secondary cell is sending relevant information of a synchronization signal block (SSB), and / or whether the terminal device needs to receive, detect or measure a synchronization signal block in a secondary cell, and the SCell is configured or indicated by the network, or pre-defined by the terminal device.

[0141] In some embodiments, the second indication information is used to indicate relevant information of whether more than one secondary cell is sending synchronization signal blocks (SSBs), and / or whether the terminal device needs to receive, detect, or measure synchronization signal blocks in more than one secondary cell. For example, the second indication information is a bitmap, and the different values ​​of each bit in the bitmap indicate whether one of the more than one SCells is currently sending SSBs, and / or whether the terminal device needs to receive, detect, or measure the SSB in one of the more than one SCells. The relationship between the value of each bit in the bitmap and whether the corresponding SCell is sending SSBs and / or whether the terminal device needs to receive, detect, or measure the SSB in one of the more than one SCells can be found in the previous text and will not be repeated here.

[0142] In some embodiments, the order of the bits corresponding to the more than one secondary cells in the bitmap is sorted in ascending order of the cell indexes of the more than one secondary cells, or, the order of the bits corresponding to the more than one secondary cells in the second indication information is sorted in descending order of the cell indexes of the more than one secondary cells, or, the order of the bits corresponding to the more than one secondary cells in the second indication information is configured or indicated by the network, or is pre-defined by the terminal device.

[0143] In some embodiments, the second indication information is used to indicate whether more than one secondary cell is sending relevant information of a synchronization signal block (SSB), and / or whether the terminal device needs to receive, detect, or measure synchronization signal blocks in more than one secondary cell. The more than one secondary cells are configured or indicated by the network, for example, it can be a network-configured SCell, or a network-configured SCell for on-demand SCell operation, or a network-configured SCell supporting on-demand SCell operation, etc., or is pre-defined by the terminal device.

[0144] In some embodiments, the second indication information includes the configuration of the measurement object corresponding to the frequency of the synchronization signal block (SSB) of the secondary cell (SCell).

[0145] If the network device configures the terminal device to measure the frequency of the SSB of the SCell, the terminal device believes that the SCell is sending the SSB.

[0146] In some embodiments, the second indication information includes the frequency information of the SSB sent by the SCell (for example, absoluteFrequencySSB) and / or the time information of the SSB sent by the SCell and / or the configuration of the periodic information of the SSB sent by the SCell, wherein the frequency information of the SSB may be the frequency point of the SSB, and the time information of the SSB may include the time position information of the SSB sent (for example, ssb-PositionsInBurst), which may be aligned with the time position of the SSB sent in the prior art (for example, Release 15 to Release 18), or may be a time position other than the time position of the SSB sent in the prior art, and the time information of the SSB may also include the time information when the SSB is to be sent, such as the radio frame number and / or time slot number and / or symbol number when the SSB is to be sent, and the periodic information of the SSB may include the period of the SSB transmission, for example, 20ms, 40ms, 160ms or 320ms, etc.

[0147] If the network device configures the frequency information and / or time information and / or period information of the SSB of the SCell, the terminal device believes that the SCell is sending the SSB or the terminal device receives (or detects or measures) the SSB of the SCell.

[0148] In some embodiments, the second indication information is a secondary cell activation / deactivation MAC CE (SCell Activation / Deactivation MAC CE).

[0149] The bit corresponding to an SCell in the secondary cell activation / deactivation MAC CE is set to 1, indicating that the SCell is activated, and the bit corresponding to an SCell in the secondary cell activation / deactivation MAC CE is set to 0, indicating that the SCell is deactivated, and vice versa. When receiving the secondary cell activation / deactivation MAC CE, the terminal device believes that an activated secondary cell is sending an on-demand SSB or the terminal device receives (or detects or measures) the SSB of the SCell, and / or believes that a deactivated secondary cell is not sending an on-demand SSB or the terminal device does not receive (or does not detect or measure) the SSB of the SCell.

[0150] In some embodiments, the second indication information includes a cell identifier (cell ID) or a cell index (cell index) of the secondary cell, and relevant information about whether the secondary cell is sending an on-demand synchronization signal block (on-demand SSB) or whether the terminal device needs to receive, detect, or measure the synchronization information block in the secondary cell. The cell identifier or cell index of the secondary cell is predefined or configured by a network device. The relevant information about whether the secondary cell is sending an on-demand synchronization signal block (on-demand SSB) or whether the terminal device needs to receive, detect, or measure the synchronization information block in the secondary cell is, for example, represented by 1 bit. The representation method can be referred to the aforementioned embodiment and will not be repeated here.

[0151] In some embodiments, in step 301, the secondary cell is a secondary cell configured with or supporting on-demand synchronization signal block transmission.

[0152] In some embodiments, the method further comprises:

[0153] After receiving the second indication information, the terminal device performs actions related to reception, detection or measurement of the SSB of the secondary cell according to the second indication information.

[0154] In some embodiments, performing an action related to reception, detection, or measurement of an SSB of a secondary cell according to the second indication information includes:

[0155] The second indication information is used to indicate that the secondary cell is not sending a synchronization signal block (SSB) and / or the terminal device needs to receive, detect or measure a synchronization signal block in a secondary cell, and the terminal device initiates or sends an uplink signal to the network device, and the uplink signal is used to request an on-demand synchronization signal block (on-demand SSB) on the secondary cell. For example, the uplink signal can be an uplink wake-up signal (Wake Up Signal, WUS), and the uplink signal can be sent to the network device in the PCell or other activated SCell. Thus, when the terminal device needs to receive the synchronization signal block of the secondary cell but the secondary cell is not sending the synchronization signal block, an uplink signal is sent to the network device so that the secondary cell sends the on-demand synchronization signal block, thereby avoiding inaccurate measurement results or detection results of the terminal device on the secondary cell, and avoiding the terminal device initiating a corresponding failure process due to failure to receive the SSB.

[0156] In some embodiments, the uplink signal is configured by a network device for a secondary cell that has or supports on-demand synchronization signal block transmission.

[0157] In some embodiments, performing an action related to reception, detection, or measurement of an SSB of a secondary cell according to the second indication information includes:

[0158] The second indication information is used to indicate that when the secondary cell is sending a synchronization signal block, the terminal device does not initiate or send an uplink signal to the network device for requesting an on-demand synchronization signal block on the secondary cell. This reduces the occupancy of uplink wireless resources and further reduces the energy consumption overhead of the NR base station.

[0159] In some embodiments, performing an action related to reception, detection, or measurement of an SSB of a secondary cell according to the second indication information includes:

[0160] The second indication information is used to indicate that the secondary cell is not sending a synchronization information block (SSB) and / or the terminal device does not need to receive or detect or measure the synchronization information block in the secondary cell, the terminal device does not receive or detect or measure the SSB on the secondary cell, and / or stops receiving or detecting or measuring the SSB on the secondary cell, and / or stops the beam failure detection process for the secondary cell. In this way, when the secondary cell does not send an SSB or the terminal device does not need to receive or detect or measure the SSB of the secondary cell, the power of the terminal device can be saved, while avoiding inaccurate detection results or measurement results of the terminal device on the secondary cell, and avoiding the terminal device from initiating a corresponding failure process.

[0161] In some embodiments, the SSB measurement on the secondary cell is, for example, a layer 1 or layer 3 measurement of the SSB, and the measurement quantity may be a reference signal receiving power (RSRP) or a reference signal receiving quality (RSRQ) or a signal to interference plus noise ratio (SINR), etc.

[0162] In some embodiments, performing an action related to reception, detection, or measurement of an SSB of a secondary cell according to the second indication information includes:

[0163] The second indication information is used to indicate that the secondary cell is sending a synchronization information block (SSB) and / or the terminal device needs to receive, detect or measure the synchronization information block in the secondary cell, and the terminal device receives, detects or measures the SSB on the secondary cell. For example, the terminal device starts receiving, detecting or measuring the SSB on the secondary cell upon receiving the second indication information; and / or

[0164] The terminal device starts to receive, detect or measure the SSB on the secondary cell after the first time period, for example, the terminal device starts to receive, detect or measure the SSB on the secondary cell after the first time period T1 after receiving the second indication information, that is, when the terminal device receives the second indication information, it starts to receive, detect or measure the SSB on the secondary cell after the first time period T1; and / or,

[0165] The terminal device receives, detects, or measures the SSB on the secondary cell in a second time period. For example, the terminal device receives, detects, or measures the SSB on the secondary cell in a second time period T2 after receiving the second indication information. The second time period T2 is, for example, a time period [t1, t2] after receiving the second indication information, where t1 and t2 are non-negative numbers.

[0166] In some embodiments, the first time period and the second time period are network configured or predefined.

[0167] In some embodiments, the terminal device receives, detects or measures the SSB of the SCell based on the frequency information of the SSB sent by the SCell and / or the time information of the SSB sent by the SCell and / or the period information of the SSB sent by the SCell included in the second indication information.

[0168] It can be seen from the above embodiments that in the data receiving method of the embodiments of the present application, the terminal device receives relevant information sent by the network device indicating whether the secondary cell is sending a synchronization signal block (SSB) and / or the indication information of whether the terminal device needs to receive or detect or measure the synchronization signal block in the secondary cell. As a result, the terminal device can perform processes related to SSB reception when the SCell sends the SSB, which is beneficial to saving power of the terminal device, while avoiding inaccurate detection results or measurement results of the SCell by the terminal device, and avoiding the UE initiating a corresponding failure process due to failure to receive the SSB.

[0169] The above embodiments are merely exemplary of the present invention, but the present invention is not limited thereto. Appropriate modifications may be made based on the above embodiments. For example, the above embodiments may be used alone, or one or more of the above embodiments may be combined.

[0170] It is worth noting that the above only describes the steps related to the present application, but the present application is not limited thereto. The data receiving method of the present application may also include other steps, and for the specific content of these steps, reference may be made to the relevant art.

[0171] The above embodiments are merely exemplary of the present invention, but the present invention is not limited thereto. Appropriate modifications may be made based on the above embodiments. For example, the above embodiments may be used alone, or one or more of the above embodiments may be combined.

[0172] Embodiments of the third aspect

[0173] An embodiment of the present application provides a data receiving method, which is described from the perspective of a terminal device.

[0174] FIG4 is another schematic diagram of a data receiving method according to an embodiment of the present application. The method is applied to a terminal device. As shown in FIG4 , the method includes:

[0175] 401, receiving third indication information related to whether a secondary cell (SCell) operation of an on-demand synchronization signal block (SSB) is supported from a network device;

[0176] 402: Perform operations related to the secondary cell according to the third indication information.

[0177] According to the above embodiment, the terminal device receives indication information sent by the network device related to whether the SCell operation of the on-demand synchronization signal block is supported. As a result, the terminal device can know which SCell has or supports on-demand SSB transmission, and perform operations related to the secondary cell according to the indication information, thereby avoiding the terminal device's failure in time and frequency synchronization of the SCell or inaccurate measurement results, thereby solving one of the above-mentioned problems existing in the prior art.

[0178] It is worth noting that FIG4 above is merely a schematic illustration of an embodiment of the present application, and the present application is not limited thereto. For example, the execution order of the various operations may be appropriately adjusted, and other operations may be added or some operations may be reduced. Those skilled in the art may make appropriate modifications based on the above description, and are not limited to the description of FIG4 above.

[0179] In some embodiments, in 401, the third indication information is used to indicate at least one of the following:

[0180] Whether the network device supports secondary cell (SCell) operation with on-demand synchronization signal blocks (SSBs);

[0181] Whether the secondary cell configured by the network device is configured or supports the sending of on-demand synchronization signal blocks.

[0182] In some embodiments, the third indication information is used to indicate whether the secondary cell configured by the network device is configured or supports sending an on-demand synchronization signal block, including:

[0183] The third indication information is used to indicate whether at least one secondary cell configured by the network device is configured or supports the sending of on-demand synchronization signal blocks.

[0184] At this time, the third indication information indicates to each secondary cell of the at least one secondary cell configured by the network device whether the secondary cell is configured with or supports sending of an on-demand synchronization signal block.

[0185] In some embodiments, the third indication information is included in system information of a primary cell (PCell).

[0186] In some embodiments, the network device may send system information including the third indication information to the terminal device when knowing the UE capability (or when receiving the first indication information in the embodiment of the first aspect of the present application), or the network device may send the system information including the third indication information without knowing the UE capability. The UE capability includes the ability of the terminal device to support SCell operation of on-demand synchronization signal blocks (also refer to the description related to the first indication information in the embodiment of the first aspect of the present application).

[0187] In some embodiments, the third indication information is carried by RRC signaling, such as an RRC reconfiguration message, an RRC resume message, etc.

[0188] In some embodiments, the network device needs to send RRC signaling carrying the third indication information to the terminal device when it knows the UE capabilities (or when it receives the first indication information in the embodiment of the first aspect of the present application). That is, when using RRC signaling to carry the third indication information, the network device needs to first know the UE capabilities (also refer to the description related to the first indication information in the embodiment of the first aspect of the present application), and then send the RRC signaling carrying the third indication information to the UE.

[0189] In some embodiments, the method further comprises:

[0190] The terminal device reports to the network device whether it supports SCell operation of the on-demand synchronization signal block.

[0191] In some embodiments, the information is, for example, the first indication information sent to the network by the data sending method described in the embodiment of the first aspect of the present application. The above content is incorporated herein and will not be repeated here.

[0192] In some embodiments, the third indication information is included in the information of the network device adding or modifying the secondary cell for the terminal device.

[0193] In some embodiments, when the third indication information is used to indicate whether the network device supports the secondary cell (SCell) operation of the on-demand synchronization signal block (on-demand SSB), different values ​​of the third indication information indicate whether the network device supports or does not support the secondary cell operation of the on-demand synchronization signal block. For example, the third indication information is 1 bit, for example, the 1 bit value is 1, indicating that the network device supports the secondary cell operation of the on-demand synchronization signal block, and the 1 bit value is 0, indicating that the network device does not support the secondary cell operation of the on-demand synchronization signal block; or, the 1 bit value is 0, indicating that the network device supports the secondary cell operation of the on-demand synchronization signal block, and the 1 bit value is 1, indicating that the network device does not support the secondary cell operation of the on-demand synchronization signal block.

[0194] In some embodiments, whether the network device supports the secondary cell operation of the on-demand synchronization signal block is indicated by whether the third indication information appears. For example, the third indication information is 1 bit, and the presence of this bit indicates that the network device supports the secondary cell operation of the on-demand synchronization signal block, and the absence of this bit indicates that the network device does not support the secondary cell operation of the on-demand synchronization signal block; or, the value of this bit is 1 or 0, indicating that the network device supports the secondary cell operation of the on-demand synchronization signal block, and the value of this bit is empty, indicating that the network device does not support the secondary cell operation of the on-demand synchronization signal block.

[0195] In some embodiments, when the third indication information is used to indicate whether a secondary cell configured by the network device is configured or supports the transmission of an on-demand synchronization signal block, different values ​​of the third indication information indicate whether the configured SCell supports or does not support the secondary cell operation of the on-demand synchronization signal block. For example, the third indication information is 1 bit, and the value of the 1 bit is 1, indicating that a secondary cell configured by the network device is configured or supports the transmission of an on-demand synchronization signal block, and the value of the 1 bit is 0, indicating that a secondary cell configured by the network device is not configured or does not support the transmission of an on-demand synchronization signal block; or, the value of the 1 bit is 0, indicating that a secondary cell configured by the network device is configured or supports the transmission of an on-demand synchronization signal block, and the value of the 1 bit is 1, indicating that a secondary cell configured by the network device is not configured or does not support the transmission of an on-demand synchronization signal block.

[0196] In some embodiments, whether the configured SCell is configured or supports the secondary cell operation of the on-demand synchronization signal block is indicated by whether the third indication information appears. For example, the third indication information is 1 bit, and the presence of this 1 bit indicates that a secondary cell configured by the network device is configured or supports the transmission of the on-demand synchronization signal block, and the absence of this 1 bit indicates that a secondary cell configured by the network device is not configured or does not support the transmission of the on-demand synchronization signal block; or, the value of this 1 bit is 1 or 0, indicating that a secondary cell configured by the network device is configured or supports the transmission of the on-demand synchronization signal block, and the value of this 1 bit is empty, indicating that a secondary cell configured by the network device is not configured or does not support the transmission of the on-demand synchronization signal block.

[0197] In some embodiments, the third indication information is used to indicate whether more than one secondary cell configured by the network device is configured with or supports the transmission of an on-demand synchronization signal block. For example, the third indication information is a bitmap, and each bit in the bitmap indicates whether one of the more than one secondary cells configured by the network device is configured with or supports the transmission of an on-demand synchronization signal block. The relationship between the value of each bit in the bitmap and whether the corresponding secondary cell is configured with or supports the transmission of an on-demand synchronization signal block can be found in the previous text and will not be repeated here.

[0198] In some embodiments, the at least one secondary cell configured by the network device includes at least one secondary cell added or modified by the network device for the terminal device. Accordingly, the third indication information is used to indicate whether a secondary cell added or modified by the network device for the terminal device is configured or supports the transmission of an on-demand synchronization signal block. For example, the third indication information is 1 bit, and different values ​​of the third indication information indicate whether a secondary cell added or modified by the network device for the terminal device is configured or supports the transmission of an on-demand synchronization signal block; or, whether the third indication information appears to indicate whether the secondary cell added or modified is configured or supports the secondary cell operation of the on-demand synchronization signal block. Reference may be made to the relevant content of the aforementioned embodiment.

[0199] Alternatively, the third indication information is used to indicate whether the more than one secondary cells added or modified by the network device for the terminal device are configured or support the sending of on-demand synchronization signal blocks. For example, the third indication information is a bitmap, which indicates whether the more than one secondary cells added or modified by the network device for the terminal device support or do not support the sending of on-demand synchronization signal blocks, and each bit in the bitmap indicates whether one of the more than one secondary cells added or modified by the network device for the terminal device is configured or supports the sending of on-demand synchronization signal blocks. The correspondence between the value of the bit and whether one of the corresponding more than one secondary cells added or modified is configured or supports the sending of on-demand synchronization signal blocks can be found in the previous text and will not be repeated here.

[0200] In some embodiments, when the third indication information is a bitmap, the order of the bits in the bitmap corresponding to the at least one added or modified secondary cell is sorted in ascending order of the cell index (cell index) of the at least one added or modified secondary cell, or, the order of the bits in the bitmap corresponding to the at least one added or modified secondary cell is sorted in descending order of the cell index (cell index) of the at least one added or modified secondary cell, or, the order of the bits in the bitmap corresponding to the at least one added or modified secondary cell is configured or indicated by the network, or pre-defined by the terminal device.

[0201] In some embodiments, the network device configures at least one secondary cell configured therein.

[0202] In some embodiments, the configuration includes configuring an uplink wake-up signal for the at least one secondary cell, or configuring frequency information and / or time information and / or period information of the SSB for the at least one secondary cell.

[0203] In some embodiments, the third indication information includes information that the network device configures an uplink signal (eg, a wake-up signal, Wake Up Signal, WUS) for the at least one secondary cell. The description of the uplink signal can refer to the embodiment of the second aspect of the present application.

[0204] When the terminal device receives information that the network device configures an uplink wake-up signal for a secondary cell, the terminal device considers that the secondary cell supports the sending of on-demand synchronization signal blocks.

[0205] In some embodiments, the third indication information includes information that the network device configures the frequency information and / or time information and / or period information of the SSB for the at least one secondary cell. The relevant description of the frequency information and / or time information and / or period information of the SSB can refer to the embodiment of the second aspect of the present application.

[0206] When the terminal device receives information that the network device configures frequency information and / or time information and / or period information of an SSB for a secondary cell, the terminal device considers that the secondary cell supports the sending of on-demand synchronization signal blocks.

[0207] In some embodiments, in step 402, performing operations related to the secondary cell according to the third indication information includes:

[0208] The third indication information is used to indicate that, when the network device supports secondary cell (SCell) operation of on-demand synchronization signal block (SSB), the terminal device considers / determines that the cell of the network device is a low-priority cell or a high-priority cell during cell selection, reselection, or switching. For example, when the terminal device may have a large data volume service or a delay-sensitive service, the terminal device considers that the cell of the network device is a low-priority cell; when the terminal device may have a low-rate service or a delay-insensitive service, the terminal device considers that the cell of the network device is a high-priority cell;

[0209] Alternatively, the third indication information is used to indicate that when the network device does not support secondary cell (SCell) operation of on-demand synchronization signal block (SSB), the terminal device considers / determines that the cell of the network device is a high-priority cell or a low-priority cell during the cell selection, reselection or switching process. For example, when the terminal device may have large data volume services or delay-sensitive services, the terminal device considers that the cell of the network device is high-priority; when the terminal device may have low-rate services or delay-insensitive services, the terminal device considers that the cell of the network device is low-priority.

[0210] In some embodiments, the handover process may be, for example, a conditional handover process or a conditional LTM process.

[0211] In some embodiments, if the cell of the network device is determined to be a low-priority cell, the terminal device does not give priority to selecting the cell of the network device as the main cell during the cell selection, reselection or switching process, or excludes the cell of the network device from the candidate cells; if the cell of the network device is determined to be a high-priority cell, the terminal device gives priority to selecting the cell of the network device as the main cell during the cell selection, reselection or switching process.

[0212] In some embodiments, in step 402, performing operations related to the secondary cell according to the third indication information includes:

[0213] The third indication information is used to indicate that when a secondary cell configured, added or modified by the network device is configured or supports the sending of an on-demand synchronization signal block, the terminal device applies the reception method and / or time-frequency synchronization method and / or measurement method and / or activation method corresponding to the on-demand synchronization signal block to the secondary cell, or the terminal device does not receive the on-demand synchronization signal block or perform time-frequency synchronization or measurement or activation of the secondary cell.

[0214] In some embodiments, when a secondary cell configured, added, or modified by the network device is configured or supports the sending of on-demand synchronization signal blocks, the network device sends information indicating whether the secondary cell is sending SSB, or information indicating whether the terminal device needs to receive, detect, or measure the secondary cell, and / or configures at least one of the time and frequency synchronization information, measurement information, and activation information of the secondary cell.

[0215] In some embodiments, the terminal device applies a reception method corresponding to the on-demand synchronization signal block to the secondary cell, including: receiving the SSB of the secondary cell according to the information sent by the network device indicating whether the secondary cell is sending the SSB, or indicating whether the terminal device needs to receive the secondary cell, or applying performance requirements related to receiving the on-demand SSB (such as the time length for receiving the SSB, the period for receiving the SSB, the number of times the SSB is received, etc.), or temporarily not receiving the SSB of the secondary cell.

[0216] In some embodiments, the information sent by the network device indicating whether the secondary cell is sending SSB, or the information indicating whether the terminal device needs to receive, detect or measure the secondary cell, can be, for example, the second indication information of the embodiment of the second aspect of the present application. The above content related to the second indication information is incorporated herein and will not be repeated here.

[0217] In some embodiments, when the second indication information is carried by RRC signaling and the third indication information is also carried by RRC signaling, the second indication information and the third indication information can be two different information elements (IE), or the second indication information and the third indication information can be implemented by different values ​​of the same IE in the RRC message.

[0218] In some embodiments, the time and frequency synchronization information of the secondary cell includes, for example, at least one of frequency information, time information, and period information of an on-demand synchronization signal block.

[0219] In some embodiments, the terminal device applies a time and frequency synchronization method corresponding to the on-demand synchronization signal block to the secondary cell, including: performing time and frequency synchronization operations with the secondary cell according to the configured time and frequency synchronization information of the secondary cell, or applying time and frequency synchronization performance requirements related to on-demand SSB (such as the time length for detecting SSB, the period for detecting SSB, the number of times of detecting SSB, etc.), or temporarily not performing the time and frequency synchronization operation of the secondary cell that is configured or supports the sending of on-demand synchronization signal blocks.

[0220] In some embodiments, the measurement information of the secondary cell includes, for example, at least one of frequency information, time information (such as SSB measurement timing configuration, SSB Measurement Timing Configuration, SMTC) and threshold information of the on-demand synchronization information block of the secondary cell.

[0221] In some embodiments, the terminal device applies a measurement method corresponding to the on-demand synchronization signal block to the secondary cell, including: measuring the secondary cell according to the configured measurement information of the secondary cell, or applying performance requirements related to measuring on-demand SSB (such as the time length of measuring SSB, the period of measuring SSB, the number of times measuring SSB, etc.), or temporarily not performing measurements on the secondary cell that is configured or supports the sending of on-demand synchronization signal blocks.

[0222] In some embodiments, the activation information of the secondary cell includes, for example, a timing requirement for activation of the secondary cell.

[0223] In some embodiments, the terminal device applies an activation method corresponding to the on-demand synchronization signal block to the secondary cell, including: activating the secondary cell according to the configured activation information of the secondary cell, or applying relevant performance requirements for detecting on-demand SSB before activating the SCell (such as the time length for detecting SSB, the period for detecting SSB, the number of times of detecting SSB, etc.), or temporarily not activating the secondary cell that is configured or supports the sending of on-demand synchronization signal blocks.

[0224] In some embodiments, the timing requirements for activation of a secondary cell that is configured or supports the sending of on-demand synchronization signal blocks are looser than the timing requirements for activation of a secondary cell that is not configured or does not support the sending of on-demand synchronization signal blocks, that is, the time or delay for activation of a secondary cell that is configured or supports the sending of on-demand synchronization signal blocks may be longer. For example, for a secondary cell that is not configured or does not support the sending of on-demand synchronization signal blocks, the activation time is 8ms, while for a secondary cell that is configured or supports the sending of on-demand synchronization signal blocks, the activation time may be greater than 8ms.

[0225] In some embodiments, in step 402, performing operations related to the secondary cell according to the third indication information includes:

[0226] The third indication information is used to indicate that when a secondary cell configured, added or modified by the network device is not configured or does not support the sending of on-demand synchronization signal blocks, the terminal device applies a reception method or time-frequency synchronization method or measurement method or activation method corresponding to the synchronization signal block (SSB) to the secondary cell.

[0227] In some embodiments, if a secondary cell configured, added, or modified by the network device is not configured with or does not support on-demand synchronization signal block transmission, the network device configures the secondary cell to transmit SSBs using an existing transmission method. Furthermore, the network device configures at least one of time and frequency synchronization information, measurement information, and activation information of an existing synchronization signal block for the secondary cell. The time and frequency synchronization information, measurement information, and activation information of the synchronization signal block are similar to those in the aforementioned embodiments.

[0228] In some embodiments, the terminal device applies a reception mode or a time-frequency synchronization mode or a measurement mode or an activation mode corresponding to a synchronization signal block to the secondary cell, including:

[0229] The terminal device performs time frequency synchronization, measurement or activation on the secondary cell according to the time frequency synchronization information and / or measurement information and / or activation information of the configured synchronization signal block.

[0230] It can be seen from the above embodiments that in the data receiving method of the embodiments of the present application, the terminal device receives indication information sent by the network device related to whether the SCell operation of the on-demand synchronization signal block is supported. As a result, the terminal device can know which SCell has or supports on-demand SSB transmission, and perform operations related to the secondary cell according to the indication information, thereby avoiding the terminal device's failure in time and frequency synchronization of the SCell or inaccurate measurement results, thereby solving one of the above-mentioned problems existing in the prior art.

[0231] The above embodiments are merely exemplary of the present invention, but the present invention is not limited thereto. Appropriate modifications may be made based on the above embodiments. For example, the above embodiments may be used alone, or one or more of the above embodiments may be combined.

[0232] It is worth noting that the above only describes the steps related to the present application, but the present application is not limited thereto.

[0234] Embodiments of the fourth aspect

[0235] An embodiment of the present application provides a data receiving method, which is described from the perspective of a network device.

[0236] FIG5 is another schematic diagram of a data receiving method according to an embodiment of the present application. The method is applied to a network device. As shown in FIG5 , the method includes:

[0237] 501. A network device receives first indication information sent by a terminal device, where the first indication information is used to indicate that the terminal device supports the secondary cell operation of the on-demand synchronization signal block, or that the terminal device does not support the secondary cell operation of the on-demand synchronization signal block.

[0238] According to the above embodiment, the network device receives indication information from the terminal device indicating whether the terminal device supports or does not support the secondary cell operation of the on-demand synchronization signal block. As a result, the network device can know the UE capabilities and help the network device determine whether to configure the UE with a secondary cell with on-demand synchronization signal block transmission or which secondary cells with on-demand synchronization signal block transmission to configure, and then perform configuration consistent with the UE capabilities, avoiding incorrect configuration or invalid configuration caused by inconsistency between the network configuration and the UE capabilities, and solving one of the above-mentioned problems existing in the prior art.

[0239] It is worth noting that FIG5 above is merely a schematic illustration of an embodiment of the present application, and the present application is not limited thereto. For example, the execution order of the various operations may be appropriately adjusted, and other operations may be added or some operations may be reduced. Those skilled in the art may make appropriate modifications based on the above description, and are not limited to the description of FIG5 above.

[0240] In some embodiments, the first indication information is included in a UE capability information message, an RRC connection request message, an RRC connection establishment complete message, an RRC reconfiguration complete message, or a UE assistance information message. For example, the terminal device may actively send the first indication information to the network device, or may send the first indication information after receiving a request from the network device.

[0241] In some embodiments, different values ​​of the first indication information indicate whether the terminal device supports SCell operation of on-demand SSB. For example, the first indication information is 1 bit, and different values ​​of the 1 bit indicate whether the terminal device supports secondary cell operation of on-demand synchronization signal blocks. The relationship between the value of the 1 bit and whether the terminal device supports or does not support secondary cell operation of on-demand synchronization signal blocks can be found in the embodiments of the first aspect of the present application. The above content is incorporated herein and will not be repeated here.

[0242] In some embodiments, whether the first indication information appears indicates whether the terminal device supports SCell operation of on-demand SSB. For example, the first indication information is 1 bit, and whether the 1 bit appears indicates whether the terminal device supports secondary cell operation of on-demand synchronization signal blocks. The relationship between whether the 1 bit appears and whether the terminal device supports or does not support secondary cell operation of on-demand synchronization signal blocks can be found in the embodiments of the first aspect of the present application. The above content is incorporated herein and will not be repeated here.

[0243] In some embodiments, the first indication information is used to indicate that the terminal device supports or does not support secondary cell operation of the on-demand synchronization signal block in at least one of the following carrier aggregation modes:

[0244] Intra-band carrier aggregation (intra-band CA);

[0245] Inter-band carrier aggregation (inter-band CA);

[0246] Intra-band co-located CA;

[0247] Intra-band non co-located CA;

[0248] Carrier aggregation within frequency range 1 (FR1);

[0249] Frequency Range 2 (FR2) intra-carrier aggregation;

[0250] FR1 and FR2 carrier aggregation.

[0251] Therefore, the terminal device indicates to the network device whether it supports or does not support the secondary cell operation of the on-demand synchronization signal block according to different carrier aggregation modes, which can help the network device determine whether to configure the UE with a secondary cell with on-demand synchronization signal block transmission or which secondary cells with on-demand synchronization signal block transmission to configure, so as to avoid incorrect configuration or invalid configuration caused by inconsistency between network configuration and UE capabilities.

[0252] In some embodiments, the terminal device uses respective first indication information for the at least one carrier aggregation mode, that is, uses different first indication information for different carrier aggregation modes.

[0253] In some embodiments, the first indication information is used to indicate whether the terminal device supports or does not support the secondary cell operation of the on-demand synchronization signal block in a carrier aggregation mode. The first indication information is, for example, 1 bit. The relationship between the value of the 1 bit and whether the terminal device supports or does not support the secondary cell operation of the on-demand synchronization signal block in a carrier aggregation mode can be found in the embodiments of the first aspect of the present application. The above content is incorporated herein and will not be repeated here.

[0254] In some embodiments, the first indication information is used to indicate whether the terminal device supports or does not support the secondary cell operation of the on-demand synchronization signal block in more than one carrier aggregation mode. The first indication information is, for example, a bitmap, wherein each bit in the bitmap indicates that the terminal device supports or does not support the secondary cell operation of the on-demand synchronization signal block in one of the more than one carrier aggregation modes. The relationship between the value of one bit in the bitmap and the support or support of the secondary cell operation of the on-demand synchronization signal block by the terminal device in one of the more than one carrier aggregation modes can be found in the embodiments of the first aspect of the present application. The above content is incorporated herein and will not be repeated here.

[0255] In some embodiments, the first indication information indicates to the terminal device whether or not to support secondary cell operation of on-demand synchronization signal blocks in one or more frequency bands or frequency band combinations supported by carrier aggregation.

[0256] Therefore, the terminal device indicates to the network device whether it supports or does not support the secondary cell operation of the on-demand synchronization signal block according to different frequency bands or frequency band combinations, which can help the network device determine whether to configure the UE with a secondary cell with on-demand synchronization signal block transmission or which secondary cells with on-demand synchronization signal block transmission to configure, so as to avoid incorrect configuration or invalid configuration caused by inconsistency between the network configuration and the UE capabilities.

[0257] In some embodiments, the first indication information indicates to the terminal device whether to support or not support the secondary cell operation of the on-demand synchronization signal block in a frequency band or frequency band combination supported by carrier aggregation. For example, the first indication information is 1 bit. The relationship between the value of the 1 bit and whether the terminal device supports or does not support the secondary cell operation of the on-demand synchronization signal block in the frequency band or frequency band combination can be found in the embodiments of the first aspect of the present application. The above content is incorporated herein and will not be repeated here.

[0258] In some embodiments, when the first indication information indicates to the terminal device whether it supports or does not support the secondary cell operation of the on-demand synchronization signal block in more than one frequency band or frequency band combination supported by carrier aggregation, the more than one frequency band or frequency band combination and the order of the bits corresponding to the more than one frequency band or frequency band combination in the first indication information are configured by the network or pre-defined by the terminal device.

[0259] Through the above embodiment, the network device receives indication information from the terminal device indicating whether the terminal device supports or does not support the secondary cell operation of the on-demand synchronization signal block. As a result, the network device can know the UE capabilities and help the network device determine whether to configure the UE with a secondary cell with on-demand synchronization signal block transmission or which secondary cells with on-demand synchronization signal block transmission to configure, and then perform configuration consistent with the UE capabilities, avoiding incorrect configuration or invalid configuration caused by inconsistency between the network configuration and the UE capabilities.

[0260] The implementation and glossary of this embodiment are similar to those of the embodiment of the first aspect of this application. The above related contents are incorporated herein and will not be repeated here.

[0261] The above embodiments are merely exemplary of the present invention, but the present invention is not limited thereto. Appropriate modifications may be made based on the above embodiments. For example, the above embodiments may be used alone, or one or more of the above embodiments may be combined.

[0262] It is worth noting that the above only describes the steps related to the present application, but the present application is not limited thereto. The data receiving method of the present application may also include other steps, and for the specific content of these steps, reference may be made to the relevant art.

[0263] The above embodiments are merely exemplary of the present invention, but the present invention is not limited thereto. Appropriate modifications may be made based on the above embodiments.
