[0136] It should be noted that, in the embodiments of this application, the process of the terminal receiving the first SSB transmission and / or the second SSB transmission is to receive all or part of the SSBs in the corresponding SSB burst set. In this case, the terminal uses the same spatial reception filter to receive all or part of the SSBs in an SSB burst set.

[0137] The following details the configuration information for the interaction between the base station and the terminal, as well as the specific methods of interaction.

[0138] In the embodiments of this application, the base station can send SSB configuration information to the terminal, and the terminal can receive the SSB configuration information sent by the base station. The configuration information is set according to actual needs.

[0139] It should be noted that, in the embodiments of this application, the configuration information may include the identifier of the target cell for transmitting SSB. For example, the target cell is a serving cell (SCell), and the configuration information includes its identifier (Identity Document, ID), i.e., SCell ID, which is used to indicate the SCell for transmitting SSB.

[0140] In the embodiments of this application, the configuration information may include a first SSB transmission configuration and / or a second SSB transmission configuration. The first SSB transmission configuration and the second SSB transmission configuration will be described in detail below.

[0141] In embodiments of this application, the first SSB transmission configuration includes one or more of the following:

[0142] First SSB transmission indication;

[0143] Number of first SSB burst sets;

[0144] First SSB burst set cycle;

[0145] First SSB transmission duration;

[0146] Indication information for the first SSB burst set containing the Physical Broadcast Channel (PBCH);

[0147] The index indication of the SSB in the first SSB burst centralized transmission;

[0148] The first SSB transmission effective time interval.

[0149] It should be noted that, in the embodiments of this application, in the first SSB transmission configuration, each SSB burst set used in the first SSB transmission is a first SSB burst set, the number of first SSB burst sets is the total number of these burst sets, the first SSB burst set period is the transmission period of the first SSB burst set, the first SSB transmission is the transmission of the first SSB burst set according to the first SSB burst set period, the first SSB transmission duration is the duration of the first SSB burst set transmission according to the first SSB burst set period, the index indicator of the SSB transmitted in the first SSB burst set is used to indicate the SSB transmitted in the first SSB burst set in the first SSB transmission, and the first SSB transmission effective time interval is reference information for determining the start time of the first SSB transmission. These information can be set according to actual needs and application scenarios, and are not limited in the embodiments of this application.

[0150] In the embodiments of this application, in the first SSB transmission configuration, the first SSB transmission indication is used to indicate whether the first SSB transmission will be performed after the configuration information is configured. The first SSB transmission indication is 1 or 0. If the first SSB transmission indication is 1, it means that the first SSB transmission will be performed after the configuration information is configured. If the first SSB transmission indication is 0, it means that the first SSB transmission will not be performed after the configuration information is configured.

[0151] It should be noted that, in the embodiments of this application, the first SSB transmission can be a dense SSB transmission to accelerate cell activation. If no SSB is sent during cell deactivation to reduce network power consumption, the cell is unknown and the first SSB transmission is required to accelerate cell activation. In this case, the first SSB transmission indication can be set to 1. If sparse SSBs are transmitted during cell deactivation, the cell is known and the first SSB transmission is not required. In this case, the first SSB transmission indication can be set to 0.

[0152] In the embodiments of this application, if the first SSB transmission indication is 1, the start time of the first SSB transmission is one of the following:

[0153] The time slot where the configuration information is located + the time interval between the first SSB transmission taking effect;

[0154] The time slot where the configuration information is located + the time interval between the first SSB transmission taking effect + 3ms;

[0155] The Hybrid Automatic Repeat Request (HARQ) feedback time slot for configuration information + the time interval for the first SSB transmission to take effect;

[0156] HARQ feedback time slot for configuration information + first SSB transmission effective time interval + 3ms;

[0157] The timing of the first SSB burst set transmission after the time slot where the configuration information is located + the time interval between the first SSB transmission and the first duration.

[0158] The timing of the first SSB burst set transmission is determined by the HARQ feedback time slot of the configuration information plus the first SSB transmission effective time interval, followed by the HARQ feedback time slot of the configuration information plus the first SSB transmission effective time interval plus the first duration.

[0159] It should be noted that, in the embodiments of this application, the specific value of the first duration can be set according to actual needs and application scenarios, and is not limited in the embodiments of this application.

[0160] In the embodiments of this application, only a portion of the first SSB burst sets may contain PBCH. In the first SSB transmission configuration, the indication information of the first SSB burst set containing PBCH can be embodied in various forms, and the embodiments of this application do not limit it.

[0161] In one embodiment of this application, the indication information of the first SSB burst set containing PBCH is a bitmap; wherein, if the m-th bit is 1, it indicates that the m-th first SSB burst set contains PBCH, and if the m-th bit is 0, it indicates that the m-th first SSB burst set does not contain PBCH, where m is a natural number greater than or equal to 1.

[0162] For example, in an embodiment of this application, the indication information of the first SSB burst set containing PBCH is a bitmap. If the second bit in the bitmap is 1, it indicates that the second first SSB burst set contains PBCH, and the index of this first SSB burst set is (2-1). If the sixth bit in the bitmap is 0, it indicates that the sixth first SSB burst set does not contain PBCH, and the index of this first SSB burst set is (6-1). It should be noted that the index of the first SSB burst set is set starting from 0.

[0163] In another embodiment of this application, the indication information of the first SSB burst set containing PBCH is the index of the first first SSB burst set containing PBCH transmitted in the first SSB transmission, and the index of the last first SSB burst set containing PBCH.

[0164] For example, in an embodiment of this application, the index of the first SSB burst set containing PBCH and the index of the last SSB burst set containing PBCH in the indication information of the first SSB burst set containing PBCH are both 6. Since the index of the first SSB burst set is set starting from 0, based on this, the (6+1)th first SSB burst set contains PBCH.

[0165] In the embodiments of this application, in the first SSB transmission configuration, the first SSB burst set period can be represented by the value n, which is used to indicate the (n+1)th period in the period set {5ms, 10ms, 20ms, 40ms, 80ms, 160ms}; where n is a natural number greater than or equal to 0.

[0166] For example, in an embodiment of this application, the first SSB burst set period is represented by the value 0, which indicates that the first SSB burst set period is actually the (0+1)th period in the period set {5ms, 10ms, 20ms, 40ms, 80ms, 160ms}, that is, the first SSB burst set period is 5ms.

These information can be set according to actual needs and application scenarios, and are not limited in the embodiments of this application.

[0174] In the embodiments of this application, the second SSB transmission indication is 1 or 0; wherein, if the second SSB transmission indication is 1, it means that the second SSB transmission will be performed after the configuration information is configured; if the second SSB transmission indication is 0, it means that the second SSB transmission will not be performed after the configuration information is configured.

[0175] It should be noted that, in the embodiments of this application, the second SSB transmission can be a normal SSB transmission, used for synchronization or measurement during and after cell activation.

[0176] In embodiments of this application, if the second SSB transmission indication is 1 and the first SSB transmission indication in the first SSB transmission configuration is 0, the start time of the second SSB transmission is one of the following:

[0194] In the embodiments of this application, the above content is an explanation of the first SSB configuration information and the second SSB configuration information. The base station sends configuration information to the terminal. The configuration information may include one or more SSB transmission configurations, which are not limited in the embodiments of this application.

[0195] In the embodiments of this application, the base station and the terminal can use different methods to indicate SSB configuration information such as SSB burst set period, transmission time length, and partial SSB burst set transmission PBCH as required. The relevant content is described in detail below.

[0196] In an embodiment of this application, an on-demand configuration method for SSB is as follows: the base station configures one or more of the following for the terminal through higher-layer radio resource control (RRC) signaling, such as Servingcellconfigcommon or Servingcellconfig: SSB configuration sequence number, number of SSB burst sets, SSB burst set period, SSB transmission duration, PBCH indication information of SSB burst sets containing PBCH, SSB transmission effective time interval, etc.

[0197] The base station triggers the transmission of SSBs via downlink signaling, such as the Media Access Control (MAC) control element (CE). The MAC CE includes one or more of the following: the identifier of the cell transmitting the SSB (i.e., the target cell), the triggered SSB configuration sequence number, the index indicator of the SSB in the burst transmission, and the SSB transmission effective time interval.

[0198] It should be noted that, in the embodiments of this application, the on-demand configuration of SSB described above can be configured with one or two sets of information such as the number of SSB burst sets, the SSB burst set period, and the SSB transmission effective time interval, according to the required SSB transmission form. If it is one set, it is actually equivalent to the relevant information in the first SSB transmission configuration or the second SSB transmission configuration described above. If it is two sets, one set is equivalent to the relevant information in the first SSB transmission configuration described above, and the other set is equivalent to the relevant information in the second SSB transmission configuration described above. This application embodiment does not limit this.

[0199] For example, the base station configures the following information via higher-layer RRC signaling:

[0200] SSB configuration sequence number 1 (i.e., the first SSB transmission configuration): number of SSB burst sets = 6, SSB burst set period = 5ms, the indication information of the SSB burst set containing PBCH is 000010, indicating that the 5th SSB burst set contains PBCH.

[0201] SSB configuration sequence number 2 (i.e., the second SSB transmission configuration): SSB burst set period = 20ms;

[0202] Assuming that SCell1 (i.e., the target cell) with SCell ID = 1 transmits sparse SSBs during deactivation, but SCell1 is unknown, the terminal receives the MAC CE sent by the base station in the primary cell (PCell) as follows: Figure 3 As shown, triggering the SSB transmission corresponds to the SSB transmission on SCell ID=1 as follows. Figure 4 As shown, SSB configuration number 1 is used to accelerate AGC, coarse synchronization, and fine synchronization during SCell1 activation. The start time is the HARQ feedback slot of MAC CE + 3ms + 0, and the period is 5ms. A total of 6 SSB burst sets are transmitted, including the 5th SSB burst set containing PBCH. Based on some prior information, such as the association between L3 measurement or wake-up signal (WUS) before SCell1 activation and SSB, the base station indicates that the actual transmission in each SSB burst set is SSB index = 0~3 (SSBs with index 0~3), and the index indicator is 11110000.

[0203] SSB configuration number 2 is used for synchronization or measurement after SCell1 is activated, such as Channel State Information (CSI) measurement. The start time is the HARQ feedback slot of MAC CE + 3ms + 5ms × 6 + SSB transmission effective time interval of 20ms. The SSB burst set period is 20ms. The actual transmission in each SSB burst set is SSB index = 0 to 3.

[0204] In an embodiment of this application, another on-demand configuration method for an SSB is as follows: the base station configures one or more of the following via higher-layer signaling, such as MACCE: the identifier of the cell (i.e., the target cell) transmitting the SSB, the first SSB transmission indication, the number of first SSB burst sets, the period of the first SSB burst set, the duration of the first SSB transmission, the indication information of the first SSB burst set containing the PBCH, the index indication of the SSBs transmitted in the first SSB burst set, the second SSB transmission indication, the period of the second SSB burst set, the index indication of the SSBs transmitted in the second SSB burst set, and the second SSB activation time interval, etc.

[0205] For example, suppose that during the deactivation of SCell1 (i.e., the target cell) with SCell ID=1, sparse SSBs are transmitted, but the SCell is unknown. The terminal receives the MAC CE sent by the base station in PCell as follows: Figure 5 As shown, the corresponding SSB transmission on SCell1 is as follows: Figure 4 As shown.

[0206] See Figure 4 and Figure 5 The first SSB transmission indication of 1 indicates that there is a first SSB transmission after MAC CE, which is used to accelerate AGC, coarse synchronization and fine synchronization during SCell1 activation. The start time of the first SSB transmission is the HARQ feedback slot of MAC CE + 3ms. The period of the first SSB burst set is the (0+1)th period of {5ms, 10ms, 20ms, 40ms, 80ms, 160ms}, which is 5ms. A total of 6 first SSB burst sets are transmitted (4 for AGC, 1 for coarse synchronization and 1 for fine synchronization). The first SSB burst set with index 4 is the one with PBCH, which is the 5th transmitted first SSB burst set. The base station indicates that the SSBs with indices 0 to 3 are actually transmitted in each first SSB burst set based on some prior information, such as L3 measurement before SCell1 activation or the association between WUS and SSB.

[0207] See Figure 4 and Figure 5 The second SSB transmission indicator being 1 indicates that there is a second SSB transmission after the MAC CE, used for synchronization or measurement after SCell1 activation. The start time of the second SSB transmission is the HARQ feedback time slot of the MAC CE + 3ms + 5ms × 10 + the second SSB transmission activation time interval (20ms). The period of the second SSB burst set is the (2+1)th period in {5ms, 10ms, 20ms, 40ms, 80ms, 160ms}, which is 20ms. The actual transmission in each second SSB burst set is SSB index = 0 to 3.

[0208] For example, suppose that during the deactivation of SCell1 (i.e., the target cell) with SCell ID=1, sparse SSBs are transmitted, but SCell1 is unknown. The terminal receives the MAC CE sent by the base station in PCell as follows: Figure 6 The corresponding SSB transmission on SCell1 is as follows: Figure 7 As shown.

[0209] See Figure 6 and Figure 7 The first SSB transmission indication of 1 indicates that there is a first SSB transmission after MAC CE, which is used to accelerate SCell1 activation. The start time of the first SSB transmission is the HARQ feedback slot of MAC CE + 3ms. The period of the first SSB burst set is 5ms. A total of 8 first SSB burst sets are transmitted within the duration of the first SSB transmission of 40ms (6 for AGC, 1 for coarse synchronization, and 1 for fine synchronization). Among them, the first SSB burst set with index 6 is the PBCH, which is the 7th transmitted first SSB burst set. The base station indicates that the actual transmission in each first SSB burst set is SSB with index 0 to 3 according to some prior information.

[0210] The second SSB transmission indicator being 1 indicates that there is a second SSB transmission after the MAC CE, used for synchronization or measurement after SCell1 activation. The start time of the second SSB transmission is the HARQ feedback time slot of the MAC CE + 3ms + 40ms + the second SSB transmission effective time interval (20ms). The period of the second SSB burst set is 20ms. The actual transmission in each second SSB burst set is the SSB with index 0 to 3.

[0211] For example, suppose that during the deactivation of SCell1 (i.e., the target cell) with SCell ID=1, sparse SSBs are transmitted, but SCell1 is known. Activation can be carried out via a second SSB according to the known SCell. The terminal receives the MAC CE sent by the base station in the PCell as follows: Figure 8 The corresponding SSB transmission on SCell1 is as follows: Figure 9 As shown.

[0212] See Figure 8 and Figure 9 A first SSB transmission indicator of 0 indicates that no first SSB transmission will occur after the MAC CE. A second SSB transmission indicator of 1 indicates that a second SSB transmission will occur after the MAC CE. This is used for synchronization or measurement during and after SCell1 activation. The start time of the second SSB transmission is the HARQ feedback slot of the MAC CE + 3ms. The period of the second SSB burst set is 20ms. The actual transmission in each second SSB burst set is SSB index = 0 to 3.

[0213] It is understood that, in the embodiments of this application, the SSB configuration information may simultaneously include the first SSB transmission configuration corresponding to the first SSB transmission and the second SSB transmission configuration corresponding to the second SSB transmission. The first SSB transmission and the second SSB transmission may be two different SSB transmission forms, and their functions may also be different. The first SSB transmission may be used to accelerate cell activation, while the second SSB transmission may be used for terminal synchronization during cell activation and for terminal measurement after cell activation. In this case, the second SSB transmission is usually executed after the first SSB transmission ends. The specific transmission forms of the first SSB transmission and the second SSB transmission are not limited in the embodiments of this application.

[0214] Based on the above configuration methods applied to base stations and terminals, it can be seen that the technical solution provided in this application embodiment, taking into account actual needs, realizes flexible configuration and indication of SSB by setting the configuration information of SSB on demand through the base station. Specifically, it can accelerate the activation of unknown cells, and can also realize flexible change of SSB transmission period by setting SSB transmission period in two SSB transmission configurations. Considering the difference between AGC, fine synchronization and coarse synchronization, it can indicate SSBs that do not contain PBCH in SSB transmission configuration, realize SSB symbol-level shutdown to obtain energy saving gain.
