The communication system 100 shown in FIG. 1 takes one terminal 101 and one network device 102 as an example.

The CU-DU structure can split the protocol layers of the access network device, and some of the functions of the protocol layers are controlled by the CU, and the remaining or all of the functions of the protocol layers are distributed in the DU and controlled by the CU. However, the present disclosure is not limited thereto.

[0167] It can be understood that the communication system described in the embodiments of the present disclosure is for more clearly illustrating the technical solutions of the embodiments of the present disclosure, and does not constitute a limitation on the technical solutions proposed by the embodiments of the present disclosure. It can be known by those skilled in the art that, as the system architecture evolves and new business scenarios appear, the technical solutions proposed by the embodiments of the present disclosure are also applicable to similar technical problems.

[0168] The following embodiments of the present disclosure can be applied to the communication system 100 shown in FIG. 1 or part of the subject, but are not limited thereto. The subjects shown in FIG. 1 are exemplary, and the communication system can include all or part of the subjects in FIG. 1, or other subjects other than FIG. 1.

[0169] Embodiments of the present disclosure can be applied to Long Term Evolution (LTE), LTE-Advanced (LTE-A), LTE-Beyond (LTE-B), SUPER 3G, IMT-Advanced, 4th generation mobile communication system (4G), 5th generation mobile communication system (5G), 5G new radio (NR), Future Radio Access (FRA), New-Radio Access Technology (RAT), New Radio (NR), New radio access (NX), Future generation radio access (FX), Global System for Mobile communications (GSM (registered trademark)), CDMA2000, Ultra Mobile Broadband (UMB), IEEE 802.11 (Wi-Fi (registered trademark)), IEEE 802.16 (WiMAX (registered trademark)), IEEE 802.20, Ultra-WideBand (UWB), Bluetooth (Bluetooth (registered trademark)), Public Land Mobile Network (PLMN) network, Device-to-Device (D2D) system, Machine to Machine (M2M) system, Internet of Things (IoT) system, Vehicle-to-Everything (V2X), system using other communication methods, next-generation system expanded based thereon, and the like. Further, a plurality of systems can be applied in combination (for example, combination of LTE or LTE-A and 5G, and the like).

[0170] It should be noted that, with the pursuit of rate, delay, high-speed mobility, energy efficiency, and the diversity and complexity of services in future life, the 3GPP (3rd Generation Partnership Project, 3rd Generation Partnership Project) international standard organization has begun to develop 5G. The main application scenarios of 5G are: enhanced mobile broadband (Enhanced Mobile Broadband, eMBB), low latency and high reliability communication (Ultra-Reliable Low-Latency Communications, URLLC), and massive machine type communication (Massive Machine Type Communication, mMTC). eMBB is still targeted at users to obtain multimedia content, services and data, and its demand is growing rapidly. On the other hand, since eMBB can be deployed in different scenarios, such as indoor, urban, rural, etc., the difference in its capabilities and requirements is also relatively large, so it cannot be generalized and must be analyzed in detail in combination with the specific deployment scenario. Typical applications of URLLC include: industrial automation, power automation, remote medical operation (surgery), traffic safety guarantee, etc. The typical characteristics of mMTC include: high connection density, small data volume, delay-insensitive service, low-cost module and long service life, etc.

[0171] Since the energy consumption of a 5G base station is four times that of an LTE base station, network energy saving is an important means for operators to reduce the cost of operating a 5G system. In some embodiments, in order to save energy for terminals in RRC_CONNECTED state, a WUS (wake up signal) is introduced. An offset before the on duration of UE C-DRX (Connected Discontinuous Reception) defines a duration for sending a WUS signal, and a WUS signal, i.e. DCI 2-6, scrambled by PS-RNTI (Power Saving RNTI) is sent during the WUS duration, which is used to indicate whether the terminal wakes up to listen to the PDCCH (Physical Downlink Control Channel) during the next UE C-DRX on duration.

[0172] In some embodiments, in order to save power for RRC_IDLE / INACTIVE terminals, paging WUS (paging wake-up signal) is introduced. That is, paging WUS, i.e., PEI (paging early indication), is sent at a certain time before PO (paging occasion), which is used to indicate whether the terminal listens to paging scheduling information in the PO. The PEI is DCI 2-7 scrambled by PEI-RNTI (paging early indication radio network temporary identifier).

[0173] In some embodiments, NES (network energy saving) has supported SSB-less SCell in the inter-band CA scenario. The SSB-less SCell does not send SSB (synchronization signal block), and the terminal achieves time-frequency synchronization on the SCell (secondary cell) through the SSB of the reference cell, L1 / L3 (layer 1 / layer 3) measurement, SCell activation, and other functions. However, SSB-less in the inter-band CA scenario has many limitations, such as PCell (primary cell) and SCell co-located and only working in frequency band FR1. Frequency band FR2 and non-co-located scenarios are not supported.

[0174] In some embodiments, R19 NES supports FR2 and non-co-located scenarios, and on demand SSB can be used as an enhancement to SSB transmission for scenarios not covered by SSB-less operation to achieve network element gain and ensure proper / enhanced SCell functions, including time / frequency synchronization, L1 / L3 measurement, and SCell activation. If the terminal needs to obtain the SSB of the on-demand SSB SCell, it can request the SSB of the on-demand SSB SCell through the UL WUS (wake-up signal). That is, the SSB of the SCell is sent based on the request, or on demand. Another possible implementation is that the network device triggers the sending of the SSB on the SCell based on the implementation, for example, the network device needs to obtain the RRM (radio resource management) measurement report of the SCell, and the network device needs to notify the terminal through indication information.

[0175] In the related art, a cell in a carrier aggregation scenario can include a secondary cell supporting a network energy saving (NES) mode and a secondary cell that is not energy saving (also referred to as a normal cell, i.e., a secondary cell that transmits an SSB according to a transmission period of the SSB). The secondary cell supporting the network energy saving (NES) mode can support an on-demand SSB function, for example, a secondary cell supporting the on-demand SSB function can trigger transmission of an SSB based on a network device. However, how to enable a terminal to learn about SSB transmission on a secondary cell in a timely manner is a problem to be solved.

[0176] To this end, embodiments of the present disclosure provide a communication method and apparatus, which can enable a terminal to learn about SSB transmission on a secondary cell in a timely manner by sending information to the terminal to inform the terminal which secondary cell or secondary cells on which the network device activates or deactivates SSB transmission, so as to facilitate the terminal to perform corresponding operations.

[0177] FIG. 2A is an interaction diagram of a communication method according to an embodiment of the present disclosure. As shown in FIG. 2A, the present disclosure relates to a communication method that can be applied to a communication system 100, and the above method includes but is not limited to the following steps.

[0178] In step S2101, the terminal 101 receives first information transmitted by the network device 102, and the first information is used to indicate activation or deactivation of SSB (Synchronization Signal Block) transmission on at least one secondary cell (SCell).

[0179] In some embodiments, activation of SSB transmission on at least one secondary cell can mean, for example, that SSB transmission on the at least one secondary cell starts. Deactivation of SSB transmission on the at least one secondary cell can mean, for example, that SSB transmission on the at least one secondary cell stops.

[0180] In some embodiments, the first information can be sent to the terminal 101 after the network device 102 triggers the transmission of SSBs on the at least one secondary cell. For example, a cell supporting the on-demand SSB function can trigger the transmission of SSBs based on the network device 102, and after the network device 102 triggers the transmission of SSBs on the cell supporting the on-demand SSB function, the network device 102 sends the first information to the terminal 101, and the terminal 101 receives the first information sent by the network device 102, where the first information is used to indicate the activation of the transmission of SSBs on the at least one secondary cell. For another example, a cell supporting the on-demand SSB function can stop the transmission of SSBs based on the network device, and after the network device stops the transmission of SSBs on the cell supporting the on-demand SSB function, the network device 102 sends the first information to the terminal 101, where the first information is used to indicate the deactivation of the transmission of SSBs on the at least one secondary cell. In some embodiments, the at least one secondary cell can include at least one first secondary cell and / or at least one second secondary cell. In some embodiments, the at least one secondary cell can include at least one first secondary cell. The first secondary cell is a cell supporting the on-demand SSB function (which can also be referred to as an on-demand SCell), and the second secondary cell is a normal cell. For example, the normal cell can be a non-energy-saving secondary cell, that is, the normal cell can be a secondary cell that transmits SSBs according to a transmission period of SSBs. Alternatively, the cell supporting the on-demand SSB function can also have other names, which are not limited in the present disclosure.

[0181] In some embodiments, the first information can be a MAC CE (Medium Access Control Control Element), and the MAC CE is associated with an LCID (logical channel identify) or an eLCID (enhanced logical channel identify). For example, the first information is identified by an LCID, and the identification of the first information is an LCID selected from an LCID reserved pool, and the LCID reserved pool includes at least one LCID. For another example, the first information is identified by an eLCID, and the identification of the first information is an eLCID selected from an eLCID reserved pool, and the eLCID reserved pool includes at least one eLCID.

[0182] In some embodiments, the first information can be a MAC CE, a first bitmap defined in the MAC CE includes at least one first indication bit, each of the at least one first indication bit corresponds to one of the at least one secondary cell, and each first indication bit is used to indicate activation or deactivation of SSB transmission on the corresponding secondary cell. The at least one secondary cell includes at least one first secondary cell and / or at least one second secondary cell, the first secondary cell is a cell supporting on-demand SSB function, and the second secondary cell is a normal cell. For example, the MAC CE can be sent in any of the following scenarios: the SCell is configured but not activated; during SCell activation; after SCell activation.

[0183] In some embodiments, the secondary cell corresponding to the first indication bit is the first secondary cell. For example, when the first indication bit is a first value, it indicates activation of SSB transmission on the first secondary cell corresponding to the first indication bit; and when the first indication bit is a second value, it indicates deactivation of SSB transmission on the first secondary cell corresponding to the first indication bit. For example, for the first secondary cell in the at least one secondary cell, when the first indication bit associated with the first secondary cell is the first value, it indicates activation of SSB transmission on the first secondary cell; and when the first indication bit associated with the first secondary cell is the second value, it indicates deactivation of SSB transmission on the first secondary cell. For example, taking 1 as the first value and 0 as the second value, when the first indication bit associated with the first secondary cell is 1, it indicates activation of SSB transmission on the first secondary cell; and when the first indication bit associated with the first secondary cell is 0, it indicates deactivation of SSB transmission on the first secondary cell. It can be understood that the first indication bit associated with the first secondary cell can also take other values, which are not limited in the present disclosure.

[0184] In some embodiments, the secondary cell corresponding to the first indication bit is the second secondary cell, and the terminal 101 ignores the first indication bit or the first indication bit associated with the second secondary cell is the second value. For example, for the second secondary cell in the at least one secondary cell, the terminal 101 ignores the first indication bit associated with the second secondary cell or the first indication bit associated with the second secondary cell is the second value. For example, the second value can be 0 or other values, which are not limited in the present disclosure.

[0185] In some embodiments, the terminal 101 does not configure the secondary cell corresponding to the first indication bit, and the terminal 101 ignores the first indication bit. For example, the first indication bit corresponds to a secondary cell associated with a cell identifier A, but the terminal does not configure the secondary cell with the cell identifier A, and the terminal 101 ignores the first indication bit.

[0186] In some embodiments, the bitmap size of the first bitmap in the MAC CE described above can be 1 byte, or can be 4 bytes, or can be other bitmap sizes, which are not limited in the disclosure. It should be noted that the specific form of the MAC CE is mainly described by taking the bitmap size of the MAC CE as 1 byte as an example, that is, the bitmap size of the MAC CE can also be other byte sizes, and the specific form of the implementation manner is similar to that of the MAC CE with the bitmap size of 1 byte, which can be referred to the description of the specific form of the MAC CE with the bitmap size of 1 byte.

[0187] In some embodiments, the MAC CE described above can also define SSB transmission information, wherein the number of the SSB transmission information is the same as the number of the secondary cells that activate SSB transmission, each secondary cell that activates SSB transmission is associated with one SSB transmission information, and the SSB transmission information is sorted according to the index size of the secondary cell that activates SSB transmission, for example, the SSB transmission information is sorted in ascending order or descending order according to the index of the secondary cell that activates SSB transmission.

[0188] For example, the bitmap size of the first bitmap in the MAC CE above can be 1 byte, the at least one secondary cell includes SCellindex 1, 2, 3, 4, 5, 6, 7 SCell, wherein SCellindex 1, 3, 5 SCell is the first secondary cell, that is, the cell supporting the on-demand SSB function (that is, SCellindex 1, 3, 5 SCell is the on-demand SCell), SCellindex 2, 4, 6 SCell is the normal cell (that is, the second secondary cell above), the terminal 101 is not configured SCellindex 7 SCell (that is, SCellindex 7 SCell is not configured to the terminal 101), then the first bitmap can include 1 reserved bit (R bit) and 7 first indication bits (for example, represented by Ci, which can also be named by other names). According to the secondary cell index (SCellindex) from small to large, each of the 7 first indication bits corresponds to one of the SCellindex 1, 2, 3, 4, 5, 6, 7 SCell, for example, C1 corresponds to the SCellindex 1 secondary cell, C2 corresponds to the SCellindex 2 secondary cell, and so on. Each first indication bit is used to indicate the SSB transmission activation or deactivation on the corresponding secondary cell. Wherein, for i respectively 1, 3, 5, the first indication bit Ci associated with the SCellindex i SCell is a first value (such as 1), indicating activating the SSB transmission of the SCellindex i SCell; the first indication bit Ci associated with the SCellindex i SCell is a second value (such as 0), indicating deactivating the SSB transmission of the SCellindex i SCell. For i respectively 2, 4, 6, the terminal 101 ignores the first indication bit Ci associated with the SCellindex i SCell, or the first indication bit Ci associated with the SCellindex i SCell is a second value (such as 0). For i is 7, the terminal 101 ignores the first indication bit C7 associated with the SCellindex 7.

[0189] In some embodiments, the first information can be a MAC CE, and the second bitmap defined in the MAC CE includes at least one second indication bit, each of the at least one second indication bit corresponding to one of the at least one secondary cell, and each second indication bit being used to indicate activation or deactivation of SSB transmission on the corresponding secondary cell. The secondary cell is a first secondary cell, and the first secondary cell is a cell supporting an on-demand SSB function. In some embodiments, the second indication bit is a first value, which is used to indicate activation of SSB transmission on the corresponding first secondary cell; and the second indication bit is a second value, which is used to indicate deactivation of SSB transmission on the corresponding first secondary cell. For example, the MAC CE can be sent in any of the following scenarios: a scenario in which an SCell is configured but not activated; a scenario during SCell activation; and a scenario after SCell activation.

[0190] In some embodiments, the first information can be a MAC CE, and the second bitmap defined in the MAC CE includes at least one second indication bit, each of the at least one second indication bit corresponding to one of the at least one secondary cell, and each second indication bit being used to indicate activation or deactivation of SSB transmission on the corresponding secondary cell. The secondary cell is a first secondary cell, and the first secondary cell is a cell supporting an on-demand SSB function. In some embodiments, the second indication bit is a first value, which is used to indicate activation of SSB transmission on the corresponding first secondary cell; and the second indication bit is a second value, which is used to indicate deactivation of SSB transmission on the corresponding first secondary cell. For example, the MAC CE can be sent in any of the following scenarios: a scenario in which an SCell is configured but not activated; a scenario during SCell activation; and a scenario after SCell activation.

[0191] In some embodiments, the MAC CE can further define SSB transmission information, wherein the number of SSB transmission information is the same as the number of the first secondary cell in which SSB transmission is activated, each of the first secondary cell in which SSB transmission is activated is associated with one SSB transmission information, and the SSB transmission information is sorted according to the index of the first secondary cell in which SSB transmission is activated, for example, the SSB transmission information is sorted according to the index of the first secondary cell in which SSB transmission is activated from small to large or from large to small.

[0192] In some embodiments, the bitmap size of the second bitmap in the MAC CE described above can be 1 byte, or can be 4 bytes, or can be other bitmap sizes, which are not specifically limited in the present disclosure. It should be noted that the specific form of the MAC CE is mainly described herein by taking the bitmap size of the MAC CE as 1 byte as an example, that is, the bitmap size of the MAC CE can also be other byte sizes, and the specific form of the implementation manner is similar to that of the MAC CE with the bitmap size of 1 byte, which can be referred to the description of the specific form of the MAC CE with the bitmap size of 1 byte as an example.

[0193] For example, taking the bitmap size of the second bitmap in the MAC CE described above as 1 byte as an example, the at least one secondary cell includes SCells with SCellindex of 1, 3, and 5, wherein the SCells with SCellindex of 1, 3, and 5 are the first secondary cells, that is, the cells supporting the on-demand SSB function (that is, the SCells with SCellindex of 1, 3, and 5 are on-demand SCells), the second bitmap can include 5 reserved bits (R bits) and 3 second indication bits (for example, denoted as Ci, which can also be named by other names). According to the on-demand SCell index (SCellindex), the 3 second indication bits are arranged from small to large, each of the 3 second indication bits corresponds to one of the SCells with SCellindex of 1, 3, and 5, for example, C1 corresponds to the SCell with SCellindex of 1, C2 corresponds to the SCell with SCellindex of 3, and C3 corresponds to the SCell with SCellindex of 5. Each second indication bit is used to indicate the activation or deactivation of SSB transmission on the corresponding secondary cell. For example, C1 indicates the activation or deactivation of SSB transmission of the SCell with SCellindex of 1, C2 indicates the activation or deactivation of SSB transmission of the SCell with SCellindex of 3, and C3 indicates the activation or deactivation of SSB transmission of the SCell with SCellindex of 5. For example, Ci is a first value (such as 1), indicating the activation of SSB transmission of the SCell with SCellindex of i; Ci is a second value (such as 0), indicating the deactivation of SSB transmission of the SCell with SCellindex of i.

[0194] Exemplarily, the MAC CE can further define SSB transmission information in addition to the second bitmap, i.e., the MAC CE can further include 0 or at least one SSB transmission information in addition to the second bitmap. The number of the SSB transmission information is the same as the number of the first secondary cells that activate SSB transmission. Exemplarily, if the number of the first secondary cells that activate SSB transmission is 0, for example, the SSB transmission of none of the SCells with SCellindex of 1, 3, 5 is activated, then the number of the SSB transmission information is 0. Exemplarily, taking the first secondary cells that activate SSB transmission as the SCell with SCellindex of 1 and the SCell with SCellindex of 3 as examples, the number of the SSB transmission information in the MAC CE is 2, the SCell with SCellindex of 1 and the SCell with SCellindex of 3 are respectively associated with one SSB transmission information, and the two SSB transmission information are sorted according to the SCellindex, for example, the two SSB transmission information are sorted according to the SCellindex from small to large or from large to small.

[0195] In some embodiments, the first information can be a MAC CE, and a third bitmap defined in the MAC CE includes at least one third indication bit, each of the at least one third indication bit corresponds to one of the at least one secondary cell, the at least one secondary cell includes at least one first secondary cell and / or at least one second secondary cell, the first secondary cell is a cell supporting on-demand SSB function, and the second secondary cell is a normal cell. Each of the third indication bits is used to indicate at least one of the following: activation or deactivation of the corresponding secondary cell; and activation or deactivation of SSB transmission on the corresponding secondary cell. Exemplarily, the sending of the MAC CE can be applicable during SCell activation.

[0196] In some embodiments, the secondary cell corresponding to the third indication bit is the first secondary cell, wherein the third indication bit is a first value, indicating to activate the first secondary cell corresponding to the third indication bit and activate SSB transmission on the first secondary cell corresponding to the third indication bit; the third indication bit is a second value, indicating to deactivate the first secondary cell corresponding to the third indication bit and deactivate SSB transmission on the first secondary cell corresponding to the third indication bit. For example, for the first secondary cell in the at least one secondary cell, the third indication bit associated with the first secondary cell is the first value, indicating to activate the first secondary cell and activate SSB transmission on the first secondary cell; the third indication bit associated with the first secondary cell is the second value, indicating to deactivate the first secondary cell and deactivate SSB transmission on the first secondary cell. For example, taking 1 as the first value and 0 as the second value, if the third indication bit associated with the first secondary cell is 1, it indicates to activate the first secondary cell and activate SSB transmission on the first secondary cell; if the third indication bit associated with the first secondary cell is 0, it indicates to deactivate the first secondary cell and deactivate SSB transmission on the first secondary cell. It can be understood that the third indication bit associated with the first secondary cell can also take other values, which are not limited in the present disclosure and will not be repeated here.

[0197] In some embodiments, the secondary cell corresponding to the third indication bit is the second secondary cell, wherein the third indication bit is a first value, indicating to activate the second secondary cell corresponding to the third indication bit; the third indication bit is a second value, indicating to deactivate the second secondary cell corresponding to the third indication bit. For example, for the second secondary cell in the at least one secondary cell, the third indication bit associated with the second secondary cell is the first value, indicating to activate the second secondary cell; the third indication bit associated with the second secondary cell is the second value, indicating to deactivate the second secondary cell. For example, taking 1 as the first value and 0 as the second value, if the third indication bit associated with the second secondary cell is 1, it indicates to activate the second secondary cell; if the third indication bit associated with the second secondary cell is 0, it indicates to deactivate the second secondary cell. It can be understood that the third indication bit associated with the second secondary cell can also take other values, which are not limited in the present disclosure and will not be repeated here.

[0198] In some embodiments, the bitmap size of the third bitmap in the MAC CE described above can be 1 byte, or can be 4 bytes, or can be other bitmap sizes, which are not limited in the disclosure. It should be noted that the specific form of the MAC CE is mainly described by taking the bitmap size of the MAC CE as 1 byte as an example, that is, the bitmap size of the MAC CE can also be other byte sizes, and the specific form of the implementation manner is similar to that of the MAC CE with the bitmap size of 1 byte. Please refer to the description of the specific form of the MAC CE with the bitmap size of 1 byte as an example.

[0199] For example, taking the bitmap size of the third bitmap in the MAC CE described above as 1 byte as an example, the at least one secondary cell includes SCellindex 1, 2, 3, 4, 5, 6, 7 SCell, wherein the SCellindex 1, 3, 5 SCell is the first secondary cell, that is, the cell supporting the on-demand SSB function (that is, the SCellindex 1, 3, 5 SCell is the on-demand SCell), and the SCellindex 2, 4, 6, 7 SCell is the normal cell (that is, the second secondary cell), then the third bitmap can include 1 reserved bit (R bit) and 7 third indication bits (for example, represented by Ci, or can be named by other names). According to the secondary cell index (SCellindex), the 7 third indication bits are arranged from small to large, and each third indication bit of the 7 third indication bits corresponds to one secondary cell among the SCellindex 1, 2, 3, 4, 5, 6, 7 SCell, for example, C1 corresponds to the SCellindex 1 secondary cell, C2 corresponds to the SCellindex 2 secondary cell, and so on. For example, for i being 1, 3, 5 respectively, the third indication bit Ci associated with the SCellindex i SCell is the first value (such as 1), indicating that the SCellindex i SCell is activated and the SSB transmission on the SCellindex i SCell is activated; the third indication bit Ci associated with the SCellindex i SCell is the second value (such as 0), indicating that the SCellindex i SCell is deactivated and the SSB transmission on the SCellindex i SCell is deactivated. For i being 2, 4, 6, 7 respectively, the third indication bit Ci associated with the SCellindex i SCell is the first value (such as 1), indicating that the SCellindex i SCell is activated; the third indication bit Ci associated with the SCellindex i SCell is the second value (such as 0), indicating that the SCellindex i SCell is deactivated.

[0200] In some embodiments, the MAC CE further defines SSB transmission information, and the number of SSB transmission information is the same as the number of the first secondary cells that activate SSB transmission, wherein each of the first secondary cells that activate SSB transmission is associated with one SSB transmission information, and the SSB transmission information is sorted according to the index of the first secondary cells that activate SSB transmission, for example, the SSB transmission information is sorted in ascending order or descending order according to the index of the first secondary cells that activate SSB transmission.

[0201] For example, the MAC CE defines SSB transmission information in addition to the third bitmap, that is, the MAC CE includes 0 or at least one SSB transmission information in addition to the third bitmap. The number of SSB transmission information is the same as the number of the first secondary cells that activate SSB transmission. For example, taking the first secondary cells that activate SSB transmission as SCellindex 1 and SCellindex 3 as examples, the number of SSB transmission information in the MAC CE is 2, and SCellindex 1 and SCellindex 3 are respectively associated with one SSB transmission information, and the two SSB transmission information are sorted in ascending order according to the SCellindex. For example, if the activated secondary cells are SCellindex 1, SCellindex 2, SCellindex 3 and SCellindex 4, SCellindex 1 and SCellindex 3 are the first secondary cells, and SCellindex 2 and SCellindex 4 are the second secondary cells, the number of SSB transmission information in the MAC CE is 2, SCellindex 1 and SCellindex 3 are respectively associated with one SSB transmission information, and the two SSB transmission information are sorted in ascending order according to the SCellindex, and SCellindex 2 and SCellindex 4 do not have corresponding SSB transmission information. For example, if the number of the first secondary cells that activate SSB transmission is 0, for example, the SSB transmission of the SCell with SCellindex 1, 3 and 5 is not activated, the number of SSB transmission information is 0.

[0202] In some embodiments, the MAC CE further defines SSB transmission information, and the number of SSB transmission information is the same as the number of activated secondary cells, wherein the activated secondary cells belong to the first secondary cells or the second secondary cells, and each activated secondary cell is associated with one SSB transmission information. The SSB transmission information is sorted according to the index of the activated secondary cell. For example, the SSB transmission information is sorted in ascending order or descending order according to the index of the activated secondary cell.

[0203] For example, the MAC CE defines SSB transmission information in addition to the third bitmap. That is, the MAC CE includes 0 or at least one SSB transmission information in addition to the third bitmap. The number of SSB transmission information is the same as the number of activated secondary cells, and the activated secondary cells belong to the first secondary cells or the second secondary cells. For example, if the number of activated secondary cells is 0, for example, the number of activated SCells in the SCells with SCellindex of 1, 2, 3, 4, 5, 6, and 7 is 0, then the number of SSB transmission information is 0. For example, if the activated secondary cells are the SCell with SCellindex of 1, the SCell with SCellindex of 2, the SCell with SCellindex of 3, and the SCell with SCellindex of 4, respectively, then the number of SSB transmission information in the MAC CE is 4, and the SCell with SCellindex of 1, the SCell with SCellindex of 2, the SCell with SCellindex of 3, and the SCell with SCellindex of 4 are each associated with one SSB transmission information, and the four SSB transmission information are sorted in ascending order or descending order according to the SCellindex. For example, for the SCell with SCellindex of 2 and the SCell with SCellindex of 4, the SSB transmission information associated with the SCell with SCellindex of 2 and the SCell with SCellindex of 4 is the second value (such as 0 or other values, which are not limited in the present disclosure).

[0204] In some embodiments, the SSB transmission information can be semi-statically configured by RRC (Radio Resource Control) signaling, that is, the SSB transmission information is not defined in the above MAC CE, but the SSB transmission information can be semi-statically configured by RRC signaling. For example, the network device 102 sends a first RRC signaling to the terminal 101, and the terminal 101 receives the first RRC signaling sent by the network device 102, and the first RRC signaling includes SSB transmission information. For example, the number of SSB transmission information in the first RRC signaling is the same as the number of the first secondary cells, and each first secondary cell is associated with one SSB transmission information. For example, the at least one secondary cell includes SCells with SCellindex of 1, 2, 3, 4, 5, 6, and 7, wherein the SCells with SCellindex of 1, 3, and 5 are the first secondary cells, that is, the cells supporting the on-demand SSB function (that is, the SCells with SCellindex of 1, 3, and 5 are on-demand SCells), and the SCells with SCellindex of 2, 4, 6, and 7 are normal cells (that is, the above-mentioned second secondary cells). The network device 102 can send a first RRC signaling to the terminal 101, and the first RRC signaling includes three SSB transmission information, which are respectively the SSB transmission information associated with the SCell with SCellindex of 1, the SSB transmission information associated with the SCell with SCellindex of 3, and the SSB transmission information associated with the SCell with SCellindex of 5.

[0205] Exemplarily, the number of SSB transmission information in the first RRC signaling is not the same as the number of the first secondary cells, for example, one SSB transmission information can be associated with (or shared by) multiple first secondary cells, such as the SSB transmission information can be configured according to frequency bands, and the first secondary cells in the same frequency band are associated with one SSB transmission information. For example, the at least one secondary cell includes SCells with SCell indexes of 1, 2, 3, 4, 5, 6, and 7, wherein the SCells with SCell indexes of 1, 3, and 5 are the first secondary cells, i.e., the cells supporting the on-demand SSB function (i.e., the SCells with SCell indexes of 1, 3, and 5 are on-demand SCells), the SCells with SCell indexes of 2, 4, 6, and 7 are normal cells (i.e., the second secondary cells), the SCell with SCell index of 1 and the SCell with SCell index of 3 are secondary cells in the same frequency band, and the network device 102 can send the first RRC signaling to the terminal 101, wherein the first RRC signaling includes two SSB transmission information, one of which is the SSB transmission information associated with the SCell with SCell index of 1 and the SCell with SCell index of 3, and the other is the SSB transmission information associated with the SCell with SCell index of 5.

[0206] In some embodiments, the first information described above can be a PDCCH (Physical Downlink Control Channel) scrambled by a first RNTI (Radio Network Temporary Identity). Exemplarily, a new RNTI (such as the first RNTI) can be defined, and the PDCCH scrambled by the first RNTI is used to indicate the activation or deactivation of SSB transmission on at least one secondary cell. Exemplarily, the network device 102 sends the PDCCH scrambled by the first RNTI to the terminal 101 on any cell (which can be a PCell or an SCell) configured for the terminal 101, and accordingly, the terminal 101 receives the PDCCH scrambled by the first RNTI sent by the network device 102 on the cell, which is used to indicate the activation or deactivation of SSB transmission on at least one secondary cell. Exemplarily, the sending of the PDCCH scrambled by the first RNTI can be applied to any of the following scenarios: the SCell is configured but not activated yet; during the activation of the SCell; after the activation of the SCell.

[0207] In some embodiments, the first RNTI scrambled PDCCH can comprise at least one first indication information, each of the at least one first indication information corresponding to one of the at least one secondary cell, each first indication information being used to indicate activation or deactivation of SSB transmission on the corresponding secondary cell; the at least one secondary cell comprising at least one first secondary cell and / or at least one second secondary cell, the first secondary cell being a cell supporting on-demand SSB function, and the second secondary cell being a normal cell.

[0208] In some embodiments, the secondary cell corresponding to the first indication information is the first secondary cell, wherein the first indication information is a first value, used to indicate activation of SSB transmission on the first secondary cell corresponding to the first indication information; and the first indication information is a second value, used to indicate deactivation of SSB transmission on the first secondary cell corresponding to the first indication information. For example, for the first secondary cell in the at least one secondary cell, the first indication information associated with the first secondary cell is the first value, used to indicate activation of SSB transmission on the first secondary cell; and the first indication information associated with the first secondary cell is the second value, used to indicate deactivation of SSB transmission on the first secondary cell. For example, taking 1 as the first value and 0 as the second value, if the first indication information associated with the first secondary cell is 1, it means that SSB transmission on the first secondary cell is activated; and if the first indication information associated with the first secondary cell is 0, it means that SSB transmission on the first secondary cell is deactivated. It can be understood that the first indication information associated with the first secondary cell can also take other values, which are not limited in the present disclosure.

[0209] In some embodiments, the secondary cell corresponding to the first indication information is the second secondary cell, and the terminal 101 ignores the first indication information; or the first indication information is the second value. For example, for the second secondary cell in the at least one secondary cell, the terminal 101 ignores the first indication information associated with the second secondary cell, or the first indication information associated with the second secondary cell is the second value. For example, the second value can be 0, or it can also be other values, which are not limited in the present disclosure.

[0210] In some embodiments, the terminal 101 is not configured with the secondary cell corresponding to the first indication information, and the terminal 101 ignores the first indication information. For example, the secondary cell corresponding to a certain first indication information is associated with a cell identifier A, but the terminal is not configured with the secondary cell with the cell identifier A, and the terminal 101 ignores the first indication information.

[0211] For example, the at least one secondary cell includes SCells with SCell indexes of 1, 2, 3, 4, 5, 6, and 7, wherein the SCells with SCell indexes of 1, 3, and 5 are first secondary cells, i.e., cells supporting the on-demand SSB function (i.e., the SCells with SCell indexes of 1, 3, and 5 are on-demand SCells), the SCells with SCell indexes of 2, 4, and 6 are normal cells (i.e., the second secondary cells), and the terminal 101 is not configured with the SCell with SCell index of 7 (i.e., the SCell with SCell index of 7 is not configured to the terminal 101), the PDCCH scrambled by the first RNTI can include seven first indication information (e.g., denoted as Ci, or can be named by other names). In ascending order of the secondary cell index (SCell index), each of the seven first indication information corresponds to one of the SCells with SCell indexes of 1, 2, 3, 4, 5, 6, and 7, for example, C1 corresponds to the SCell with SCell index of 1, C2 corresponds to the SCell with SCell index of 2, and so on. Each of the first indication information is used to indicate the activation or deactivation of SSB transmission on the corresponding secondary cell. For i being 1, 3, and 5 respectively, the first indication information Ci associated with the SCell with SCell index i is a first value (e.g., 1), indicating the activation of SSB transmission of the SCell with SCell index i; the first indication information Ci associated with the SCell with SCell index i is a second value (e.g., 0), indicating the deactivation of SSB transmission of the SCell with SCell index i. For i being 2, 4, and 6 respectively, the terminal 101 ignores the first indication information Ci associated with the SCell with SCell index i, or the first indication information Ci associated with the SCell with SCell index i is the second value (e.g., 0). For i being 7, the terminal 101 ignores the first indication information C7 associated with the SCell with SCell index 7.

[0212] In some embodiments, the PDCCH scrambled by the first RNTI can include at least one second indication information, each of the at least one second indication information corresponding to one of the at least one secondary cell, each of the second indication information being used to indicate the activation or deactivation of SSB transmission on the corresponding secondary cell, the secondary cell being a first secondary cell, the first secondary cell being a cell supporting the on-demand SSB function. In some embodiments, the second indication information is a first value, indicating the activation of SSB transmission on the corresponding first secondary cell; the second indication information is a second value, indicating the deactivation of SSB transmission on the corresponding first secondary cell.

[0213] For example, the at least one secondary cell includes SCells with SCellindex 1, 3, 5, wherein the SCells with SCellindex 1, 3, 5 are the first secondary cells, i.e., the cells supporting on-demand SSB function (i.e., the SCells with SCellindex 1, 3, 5 are on-demand SCells), the PDCCH scrambled by the first RNTI can include 3 second indication information (e.g., denoted as Ci, or other names can be used). According to the index (SCellindex) of the on-demand SCell, the 3 second indication information are arranged from small to large, each of the 3 second indication information corresponds to one of the SCells with SCellindex 1, 3, 5, for example, C1 corresponds to the SCell with SCellindex 1, C2 corresponds to the SCell with SCellindex 3, and C3 corresponds to the SCell with SCellindex 5. Each of the second indication information is used to indicate the SSB transmission activation or deactivation on the corresponding secondary cell. For example, C1 indicates the SSB transmission activation or deactivation of the SCell with SCellindex 1, C2 indicates the SSB transmission activation or deactivation of the SCell with SCellindex 3, and C3 indicates the SSB transmission activation or deactivation of the SCell with SCellindex 5. For example, Ci is a first value (e.g., 1), indicating the SSB transmission activation of the SCell with SCellindex i; Ci is a second value (e.g., 0), indicating the SSB transmission deactivation of the SCell with SCellindex i.

[0214] In some embodiments, the network device 102 sends the first RRC signaling to the terminal 101, and accordingly, the terminal 101 receives the first RRC signaling sent by the network device 102, and the first RRC signaling includes SSB transmission information. In some embodiments, the number of SSB transmission information is the same as the number of the first secondary cells, and each first secondary cell is associated with one SSB transmission information. That is, the PDCCH scrambled by the first RNTI can be used to indicate the activation or deactivation of the SSB transmission on at least one secondary cell. The SSB transmission information of the first secondary cell can also be semi-statically configured by the first RRC signaling. For example, the number of SSB transmission information in the first RRC signaling is the same as the number of the first secondary cells, and each first secondary cell is associated with one SSB transmission information. For example, the at least one secondary cell includes SCells with SCellindex of 1, 2, 3, 4, 5, 6, and 7, wherein the SCells with SCellindex of 1, 3, and 5 are the first secondary cells, i.e., the cells supporting the on-demand SSB function (i.e., the SCells with SCellindex of 1, 3, and 5 are the on-demand SCells), and the SCells with SCellindex of 2, 4, 6, and 7 are normal cells (i.e., the second secondary cells), the network device 102 can send the first RRC signaling to the terminal 101, and the first RRC signaling includes three SSB transmission information, which are respectively the SSB transmission information associated with the SCell with SCellindex of 1, the SSB transmission information associated with the SCell with SCellindex of 3, and the SSB transmission information associated with the SCell with SCellindex of 5.

[0215] For example, the number of SSB transmission information in the first RRC signaling is not the same as the number of the first secondary cells, for example, one SSB transmission information can be associated with (or shared by) multiple first secondary cells, for example, the SSB transmission information can be configured according to the frequency band, and the first secondary cells in the same frequency band are associated with one SSB transmission information. For example, the at least one secondary cell includes SCells with SCell indexes 1, 2, 3, 4, 5, 6, and 7, wherein the SCells with SCell indexes 1, 3, and 5 are the first secondary cells, i.e., the cells supporting the on-demand SSB function (i.e., the SCells with SCell indexes 1, 3, and 5 are on-demand SCells), the SCells with SCell indexes 2, 4, 6, and 7 are normal cells (i.e., the second secondary cells), the SCell with SCell index 1 and the SCell with SCell index 3 are secondary cells in the same frequency band, and the network device 102 can send the first RRC signaling to the terminal 101, wherein the first RRC signaling includes two SSB transmission information, one of which is the SSB transmission information associated with the SCell with SCell index 1 and the SCell with SCell index 3, and the other is the SSB transmission information associated with the SCell with SCell index 5.

[0216] In some embodiments, the first information described above can be, for example, a second RRC signaling, and the second RRC signaling can include third indication information. The third indication information is used to indicate at least one of the following: the index of the cell activating SSB transmission, and the cell activating SSB transmission belongs to at least one secondary cell; the index of the cell deactivating SSB transmission, and the cell deactivating SSB transmission belongs to at least one secondary cell. For example, a new RRC signaling (i.e., a second RRC signaling) is defined, which indicates the cell activating and / or deactivating SSB transmission, for example, the index of the cell activating and / or deactivating SSB transmission.

[0217] In some embodiments, the second RRC signaling further comprises SSB transmission information, wherein the number of SSB transmission information is the same as the number of cells with activated SSB transmission, each cell with activated SSB transmission is associated with one SSB transmission information, and the SSB transmission information is ordered according to the index of the cell with activated SSB transmission, for example, the SSB transmission information is ordered according to the index of the cell with activated SSB transmission in ascending order or in descending order. In some embodiments, the second RRC signaling further comprises SSB transmission information, wherein the number of SSB transmission information is the same as the number of first secondary cells, each first secondary cell is associated with one SSB transmission information, and the SSB transmission information is ordered according to the index of the first secondary cell, for example, the SSB transmission information is ordered according to the index of the first secondary cell in ascending order or in descending order.

[0218] In some embodiments, the SSB transmission information can comprise at least one of the following: SSB start position; SSB end position; SSB duration; number of SSB transmission bursts; interval between two consecutive SSB bursts. For example, the start time and / or end time can be represented by radio frame, radio subframe, time slot, time domain symbol, etc., for example, the start time and / or end time can be a relative time position, for example, an offset from the first information, indicating the SSB start time and / or SSB end time. For example, the SSB duration can be measured by hour, minute, second, millisecond, microsecond, nanosecond, etc., or by radio frame, radio subframe, time slot, time domain symbol, etc. In some embodiments, the terms “start time”, “start position”, etc. can be replaced by each other. In some embodiments, the terms “end time”, “end position”, etc. can be replaced by each other.

[0226] FIG. 2B is an interaction diagram of a communication method according to an embodiment of the present disclosure. As shown in FIG. 2B, the embodiment of the present disclosure relates to a communication method applicable to the communication system 100, and the above method includes but is not limited to the following steps.

[0227] In step S2201, the terminal 101 receives second information sent by the network device 102 on the first secondary cell.

[0228] In some embodiments, the second information is a PDCCH scrambled by RNTI, and the second information is used to indicate the activation or deactivation of SSB transmission on the first secondary cell, and the first secondary cell is a cell supporting the on-demand SSB function. For example, the sending of the second information can be applied to any of the following scenarios: after the SCell is activated.

[0229] In some embodiments, the activation of SSB transmission on the first secondary cell can mean that the SSB on the first secondary cell starts to send, for example. The deactivation of SSB transmission on the first secondary cell can mean that the SSB on the first secondary cell stops sending, for example.

[0230] In some embodiments, the second information can be sent to the terminal 101 by the network device 102 after triggering the SSB transmission on the first secondary cell. For example, the first secondary cell can be triggered to send SSBs based on the implementation of the network device 102, and the network device 102 can send the second information to the terminal 101 on the first secondary cell after triggering the SSB transmission on the first secondary cell. Alternatively, the second information can be sent to the terminal 101 by the network device 102 before triggering the SSB transmission on the first secondary cell. For example, the first secondary cell can be triggered to send SSBs based on the implementation of the network device 102, and the network device 102 can send the second information to the terminal 101 on the first secondary cell before triggering the SSB transmission on the first secondary cell. Accordingly, the terminal 101 can receive the second information sent by the network device 102 on the first secondary cell, and the second information can be a PDCCH scrambled by an RNTI, which is used to indicate the activation of the SSB transmission on the first secondary cell. For example, the first secondary cell can be triggered to stop sending SSBs based on the implementation of the network device 102, and the network device 102 can send the second information on the first secondary cell after stopping the SSB transmission on the first secondary cell. Accordingly, the terminal 101 can receive the second information sent by the network device 102 on the first secondary cell, and the second information can be a PDCCH scrambled by an RNTI, which is used to indicate the deactivation of the SSB transmission on the first secondary cell.

[0231] In some embodiments, the second information can include fourth indication information, which is used to indicate the activation or deactivation of the SSB transmission on the first secondary cell. In some embodiments, the fourth indication information can be a first value, which is used to indicate the activation of the SSB transmission on the first secondary cell, and the fourth indication information can be a second value, which is used to indicate the deactivation of the SSB transmission on the first secondary cell. That is, the “activation of the SSB transmission” and the “deactivation of the SSB transmission” can be associated with the same RNTI (i.e., the same RNTI), and additional indication information (i.e., the fourth indication information) is needed to indicate the activation or deactivation of the SSB transmission.

[0232] In some embodiments, the optional implementation of the second information sent by the receiving network device on the first secondary cell can include: the receiving network device receiving second information sent by the network device on the first secondary cell, the second information being a PDCCH scrambled by a second RNTI, the PDCCH scrambled by the second RNTI being used to indicate activation of SSB transmission on the first secondary cell; or, the receiving network device receiving second information sent by the network device on the first secondary cell, the second information being a PDCCH scrambled by a third RNTI, the PDCCH scrambled by the third RNTI being used to indicate deactivation of SSB transmission on the first secondary cell. That is, "activation of SSB transmission" and "deactivation of SSB transmission" can be associated with different RNTIs, without the need for additional indication information to indicate activation or deactivation of SSB transmission. For example, a PDCCH scrambled by a second RNTI indicates activation of SSB transmission on the first secondary cell, a PDCCH scrambled by a third RNTI indicates deactivation of SSB transmission on the first secondary cell, and the second RNTI and the third RNTI are different wireless network temporary identifications.

[0233] In step S2202, the terminal 101 receives the first RRC signaling sent by the network device 102.

[0234] In some embodiments, the network device 102 sends the first RRC signaling to the terminal 101, and accordingly, the terminal 101 receives the first RRC signaling sent by the network device 102, and the first RRC signaling includes SSB transmission information.

[0235] In some embodiments, the number of SSB transmission information is the same as the number of the first secondary cells, and each first secondary cell is associated with one SSB transmission information. That is, the PDCCH scrambled by the RNTI can be used to indicate the activation or deactivation of the SSB transmission on the first secondary cell. The SSB transmission information of the first secondary cell can also be semi-statically configured by the first RRC signaling. For example, the number of SSB transmission information in the first RRC signaling is the same as the number of the first secondary cells, and each first secondary cell is associated with one SSB transmission information. For example, the at least one secondary cell includes SCells with SCellindex 1, 2, 3, 4, 5, 6, and 7, wherein the SCells with SCellindex 1, 3, and 5 are the first secondary cells, i.e., the cells supporting the on-demand SSB function (i.e., the SCells with SCellindex 1, 3, and 5 are the on-demand SCells), and the SCells with SCellindex 2, 4, 6, and 7 are normal cells (i.e., the second secondary cells). The network device 102 can send the first RRC signaling to the terminal 101, and the first RRC signaling includes three SSB transmission information, which are respectively the SSB transmission information associated with the SCell with SCellindex 1, the SSB transmission information associated with the SCell with SCellindex 3, and the SSB transmission information associated with the SCell with SCellindex 5.

[0236] Exemplarily, the number of SSB transmission information in the first RRC signaling is not the same as the number of the first secondary cells, for example, one SSB transmission information can be associated with (or shared by) multiple first secondary cells, for example, the SSB transmission information can be configured according to a frequency band, and the first secondary cells in the same frequency band are associated with one SSB transmission information. For example, the at least one secondary cell includes SCells with SCell indexes of 1, 2, 3, 4, 5, 6, and 7, wherein the SCells with SCell indexes of 1, 3, and 5 are first secondary cells, that is, cells supporting the on-demand SSB function (that is, the SCells with SCell indexes of 1, 3, and 5 are on-demand SCells), the SCells with SCell indexes of 2, 4, 6, and 7 are normal cells (that is, the second secondary cells), the SCell with SCell index 1 and the SCell with SCell index 3 are secondary cells in the same frequency band, and the network device 102 can send the first RRC signaling to the terminal 101, wherein the first RRC signaling includes two SSB transmission information, one of which is the SSB transmission information associated with the SCell with SCell index 1 and the SCell with SCell index 3, and the other is the SSB transmission information associated with the SCell with SCell index 5.

[0237] In some embodiments, the SSB transmission information can include, but is not limited to, at least one of the following: SSB start position; SSB end position; SSB duration; number of SSB transmission bursts; interval between two consecutive SSB bursts. Exemplarily, the start time and / or end time can be represented by radio frames, radio subframes, time slots, time domain symbols, etc. Exemplarily, the start time and / or end time can be a relative time position, for example, an offset from the first information, indicating the SSB start time and / or the SSB end time. Exemplarily, the SSB duration can be measured by hours, minutes, seconds, milliseconds, microseconds, nanoseconds, etc., or by radio frames, radio subframes, time slots, time domain symbols, etc. In some embodiments, the terms “start time”, “start position”, etc. can be replaced with each other. In some embodiments, the terms “end time”, “end position”, etc. can be replaced with each other.

[0238] The method related to the embodiments of the present disclosure can include at least one of steps S2201-S2202.

[0239] In some embodiments, the steps S2201 and S2202 can be exchanged in order or executed simultaneously.

[0240] In some embodiments, step S2202 is optional, and one or more of these steps can be omitted or replaced in different embodiments.

[0241] In some embodiments, other optional implementations can be described before or after the description of Figure 2B.

[0242] Figure 2C is an interaction diagram of a communication method according to an embodiment of the present disclosure. As shown in Figure 2C, the embodiments of the present disclosure relate to a communication method applicable to the communication system 100, and the method includes but is not limited to the following steps.

[0243] Step S2301, the terminal 101 receives the third information sent by the network device 102, the third information is the PDCCH scrambled by the RNTI, and the third information is used to indicate the SSB transmission activation or deactivation of at least one first cell group.

[0244] In some embodiments, the cells in the at least one first cell group are all cells supporting the on-demand SSB function.

[0245] In some embodiments, the third information described above can be sent by the network device 102 on any cell (such as PCell or SCell) configured for the terminal 101. For example, the network device 102 sends the third information to the terminal 101 on any cell (such as PCell or SCell) configured for the terminal 101, and the terminal 101 receives the third information sent by the network device on the cell. The third information can be the PDCCH scrambled by the RNTI, and is used to indicate the SSB transmission activation or deactivation of at least one first cell group. That is, the SCell can be grouped by RRC configuration, and the SSB transmission of an entire group of SCells can be activated or deactivated by DCI. The SCells in this group are all cells supporting the on-demand SSB function. The network device 102 can indicate the SSB transmission activation or deactivation of a certain cell group through the third information (i.e. the PDCCH scrambled by the RNTI).

[0246] In some embodiments, the third information described above can include at least one fifth indication information, each of the at least one fifth indication information corresponds to a first cell group in the at least one first cell group, and each fifth indication information is used to indicate the SSB transmission activation or deactivation of the corresponding first cell group. In some embodiments, the fifth indication information is a first value, which is used to indicate the activation of the SSB transmission of the corresponding first cell group; and the fifth indication information is a second value, which is used to indicate the deactivation of the SSB transmission of the corresponding first cell group.

[0247] For example, taking SCells with SCellindex of 1, 2, 3, 4, 5, 6, and 7 as an example, the SCells with SCellindex of 1, 3, and 5 are first secondary cells, that is, cells supporting the on-demand SSB function (that is, the SCells with SCellindex of 1, 3, and 5 are on-demand SCells), the SCells with SCellindex of 2, 4, 6, and 7 are normal cells (that is, second secondary cells), and the SCell with SCellindex of 1 and the SCell with SCellindex of 3 are grouped into a group (for example, denoted as a first group) and the SCell with SCellindex of 5 is grouped into a group (for example, denoted as a second group) through RRC configuration. For example, the RNTI scrambled PDCCH carries the fifth indication information of the activated or deactivated SCell group, for example, the RNTI scrambled PDCCH can include two fifth indication information (for example, denoted as Ci, which can also be named by other names), C1 corresponds to the first group, and C2 corresponds to the second group, that is, each fifth indication information corresponds to an SCell group, Ci (i is 1 or 2) is set to 1 to indicate that the SSB transmission of the SCell group corresponding to Ci is activated, specifically, the SSB transmission of all SCells in the SCell group corresponding to Ci is activated, Ci (i is 1 or 2) is set to 0 to indicate that the SSB transmission of the SCell group corresponding to Ci is deactivated, specifically, the SSB transmission of all SCells in the SCell group corresponding to Ci is deactivated. For example, C1 is set to 1 to indicate that the SSB transmission of the first group is activated, that is, the SSB transmission of the SCell with SCellindex of 1 and the SCell with SCellindex of 3 is activated. C2 is set to 2 to indicate that the SSB transmission of the second group is deactivated, that is, the SSB transmission of the SCell with SCellindex of 5 is deactivated.

[0286] The optional implementation of step S5302 can refer to the optional implementation of step S2301 in FIG. 2C and other associated parts in the embodiments related to FIG. 2C, which will not be repeated here.

[0287] In some embodiments, the above method can include the method described in the above terminal-side, network device-side, and other embodiments, which will not be repeated here.

[0288] It is worth noting that in the carrier aggregation scenario, the first secondary cell can be triggered to send SSB based on the network. After the network device triggers the SSB transmission on the SCell, the terminal needs to be indicated by the indication information. However, the specific form of the indication information and whether the use scenario of the indication information needs to be specified are problems. Based on this, the present disclosure proposes an indication method for sending SSB, which will be described in detail below in combination with specific embodiments.

[0289] In some embodiments, a new MAC CE is defined to indicate SSB transmission activation / deactivation on the SCell.

[0290] For example, the new MAC CE can be a 1 byte bitmap (bit map size is 1 byte) or a 4 byte bitmap (bit map size is 4 bytes). The 1 byte bitmap MAC CE is associated with an LCID or an eLCID, and the 4 byte bitmap is associated with an LCID or an eLCID.

[0291] For example, the 1 byte bitmap contains one R bit (reserved bit) and 7 indication bits, e.g. Ci (other naming can be used). Each of the 7 indication bits corresponds to one SCell, e.g. C1 corresponds to the SCell of SCellindex 1, and so on, in ascending order of SCellindex. If a MAC entity (representing a terminal) is configured with the SCell of SCellindex i, this field indicates the SSB transmission activation / deactivation status of the SCell of SCellindex i. For example, activation means that the SSB on this SCell starts to transmit, and deactivation means that the SSB on this SCell stops to transmit. If a MAC entity is not configured with the SCell of SCellindex i or the SCell corresponding to SCellindex i is not an on-demand SSB SCell, the terminal ignores this Ci. Or, the SCell corresponding to SCellindex i is not an on-demand SSB SCell, this indication bit is set to 0. For example, Ci set to 1 means to activate the SSB of SCellindex i, and Ci set to 0 means to deactivate the SSB of SCellindex i.

[0292] For example, the Ci only corresponds to on-demand SCell, in ascending order of on-demand SCell index, for example, the SCell of SCellindex 1, 3, 5 are on-demand SCell, then C1 indicates to activate / deactivate the SSB transmission of SCellindex 1, C2 indicates to activate / deactivate the SSB transmission of SCellindex 3, and so on.

[0293] For example, the 4 byte bitmap contains one R bit and 31 indication bits. Other specific details refer to the relevant description of the 1 byte bitmap above, which will not be repeated here.

[0294] Exemplarily, the MAC CE can contain 0 or more SSB transmission information in addition to the bitmap, for example including at least one of: SSB starting position; SSB ending position; SSB duration; number of SSB transmission bursts; interval between two consecutive bursts; etc. Exemplarily, the starting position / ending position can be indicated by radio frame, radio subframe, time slot, time domain symbol, etc. Exemplarily, the starting position / ending position can be a relative time position, for example an offset from the MAC CE, indicating the SSB starting position / ending position. Exemplarily, the SSB duration can be measured by time, minute, second, millisecond, microsecond, nanosecond, etc. or by radio frame, radio subframe, time slot, time domain symbol, etc. Exemplarily, each SCell with activated SSB transmission is associated with one SSB transmission information. Each SCell with deactivated SSB transmission is not associated with SSB transmission information. The 0 or more SSB transmission information are arranged in ascending order of the index of the activated SCell or in ascending order of the index of the activated on-demand SCell. Optionally, the SSB transmission information can also be semi-statically configured by RRC signaling (e.g. the first RRC signaling in the disclosure).

[0295] Exemplarily, the new MAC CE is applicable to one of scenario 1, scenario 2, scenario 3. Wherein, scenario 1 can refer to that the SCell is configured (or added) but the SCell has not been activated yet; scenario 2 refers to the SCell activation period; scenario 3 refers to after the SCell is activated.

[0296] As an example, as one possible implementation, reuse the existing SCell activation / deactivation MAC CE. As an example, the MAC CE is applicable to scenario 2. For example, the terminal receives a SCell activation / deactivation MAC CE, the Ci indicates bit indicates the activation / deactivation status of the SCell with SCell index i, and can also indicate the SSB transmission activation / deactivation status of the SCell with SCell index i, for example, Ci is 1, indicating that the SCell with SCell index i is activated and the SSB transmission is activated. Ci is 0, indicating that the SCell with SCell index i is deactivated and the SSB is deactivated. Optionally, the MAC CE can also contain 0 or more SSB transmission information, for example, including at least one of the following: SSB start position; SSB end position; SSB duration; number of SSB transmission bursts; interval between two consecutive bursts, etc. The 0 or more SSB transmission information is arranged in ascending order of the index of the activated SCell. Or the SSB transmission information can also be semi-statically configured by RRC signaling (such as the first RRC signaling in the present disclosure).

[0297] As an example, if it is determined that the SCell associated with SCell index i is not an on-demand SSB SCell, Ci is 1 only indicates to activate the SCell. One possible way is that the SCell has no corresponding SSB transmission information, that is, only the SCell that is activated and on-demand SSB has corresponding SSB transmission information. (Assuming that SCells with SCell indexes 1-5 are configured, and SCells with SCell indexes 1, 3, and 5 are on-demand SCells. If SCells with SCell indexes 1, 2, 4, and 5 are activated, only SCells with SCell indexes 1 and 5 have corresponding SSB transmission information, and SCells with SCell indexes 2 and 4 do not have corresponding SSB transmission information); one possible way is that the SCell has corresponding SSB transmission information, but the configuration is 0 or other special values. If Ci is 0, the SCell has no corresponding SSB transmission information.

[0298] As an example, if it is determined that the SCell associated with SCell index i is an on-demand SSB SCell, if the on-demand SCell, Ci is 1 indicates to activate the SCell and activate the SSB transmission. The SCell has corresponding SSB transmission information. If Ci is 0, it indicates to deactivate the SCell and deactivate the SSB transmission, and the SCell has no corresponding SSB transmission information.

[0299] In some embodiments, a new RNTI is defined to indicate the activation / deactivation of SSB transmission on SCell.

[0300] For example, a new RNTI / DCI is defined, and the PDCCH scrambled by the RNTI is used to indicate the activation / deactivation of SSB transmission on SCell. This scheme is applicable to scenario 3. If the network device activates / deactivates the SSB of a certain SCell, it sends the PDCCH scrambled by the RNTI on the SCell. For example, the activation and deactivation can be associated with different RNTIs, and for example, the activation and deactivation are associated with the same RNTI. Specifically, the activation and deactivation are associated with the same RNTI, and an additional indication information (such as the fourth indication information in this disclosure) is needed to indicate the activation or deactivation.

[0301] For example, the SSB transmission information can be semi-statically configured by RRC signaling (such as the first RRC signaling in this disclosure), for example, including at least one of the following: SSB starting position; SSB ending position; SSB duration; number of SSB transmission bursts; interval between two consecutive bursts, etc.

[0302] For example, a new RNTI / DCI is defined, and the PDCCH scrambled by the RNTI (such as the first PDCCH scrambled by the RNTI in this disclosure) is used to indicate the activation / deactivation of SSB transmission on SCell. This scheme is applicable to scenario 1, scenario 2, and scenario 3. The PDCCH scrambled by the RNTI can be sent on the PCell or other SCell, for example, the activation and deactivation can be associated with different RNTIs, and for example, the activation and deactivation are associated with the same RNTI. Specifically, the activation and deactivation are associated with the same RNTI, and an additional indication information is needed to indicate the activation or deactivation. The RNTI scrambled PDCCH DCI / RNTI scrambled PDCCH carries the identification indication information (such as the first indication information or the second indication information in this disclosure) of the activated / deactivated SCell. For example, a bitmap, each bit corresponds to a SCell. Set to 1 indicates that the SCell activates the SSB transmission, and set to 0 indicates that the SCell deactivates the SSB transmission.

[0303] In another possible implementation, the SCells are first grouped by RRC configuration, and a whole group of SCells is activated or deactivated SSB transmission by DCI. The SCells in this group are all on-demand SSB SCells. The indication information (e.g., the fifth indication information in the present disclosure) of the activated / deactivated SCell group is carried in the DCI / RNTI scrambled PDCCH. For example, a bitmap, each bit corresponds to an SCell group, and is set to 1 to indicate activating SSB transmission of the SCell group, and is set to 0 to indicate deactivating SSB transmission of the SCell group.

[0304] In some embodiments, a new RRC signaling (e.g., the second RRC signaling in the present disclosure) is defined to indicate the SSB transmission activation / deactivation on the SCell.

[0305] For example, a new RRC signaling is defined to indicate the SCell on which the SSB transmission is activated / deactivated, e.g., to indicate the SCell index on which the SSB transmission is activated / deactivated. For example, the new RRC signaling can further include SSB transmission information, e.g., including at least one of the following: SSB start position; SSB end position; SSB duration; number of SSB transmission bursts; interval between two consecutive bursts; etc.
