Specifically, the use of terms such as "exemplary" or "for example" is intended to present the relevant concepts in a specific manner. The terms "in which" or "under which circumstances" used in this disclosure are used to indicate conditions.

[0152] The terminal involved in the embodiments of the present disclosure can refer to a device that provides voice and / or data connectivity to a user, a handheld device with wireless connection function, or other processing devices connected to a wireless modem, etc. In different systems, the name of the terminal can also be different, for example, in the 5G system or the 6G system, the terminal can be called user equipment (User Equipment, UE). The wireless terminal can be a USB storage device, other personal computer memory devices and a dongle, and can also communicate with one or more core networks (Core Network, CN) through a radio access network (Radio Access Network, RAN). The wireless terminal can be a mobile terminal, such as a mobile phone (also known as a "cellular" phone) and a computer with a mobile terminal, for example, it can be a portable, pocket, handheld, built-in computer or vehicle-mounted mobile device, which exchanges voice and / or data with a radio access network. For example, personal communication service (Personal Communication Service, PCS) phones, cordless phones, session initiation protocol (Session Initiated Protocol, SIP) phones, wireless local loop (Wireless Local Loop, WLL) stations, personal digital assistants (Personal Digital Assistant, PDA), personal computers, tablet computers, machine type communication (Machine-type Communication, MTC) terminals and other devices. The wireless terminal can also be called a system, a subscriber unit, a subscriber station, a mobile station, a mobile, a remote station, an access point, a remote terminal, an access terminal, a user terminal, a user agent, a user device, and a wireless access device and router / modem that meet the limitations of the present definition, etc. The embodiments of the present disclosure are not limited.

[0153] The network device involved in the embodiments of the present disclosure can be a base station, which can include multiple cells serving terminals. According to different application occasions, the base station can also be referred to as an access point, or can be a device in an access network that communicates with wireless terminals through one or more sectors over an air interface, or other names. The network device can be used to exchange received air frames and Internet Protocol (IP) packets as a router between wireless terminals and the rest of the access network, which can include an Internet Protocol (IP) communication network.

[0154] The synchronization block (Synchronization Signal / PBCH Block, SSB) involved in the embodiments of the present disclosure can be referred to as an on-demand SSB, which can be understood as an SSB sent on demand.

[0155] In the related art, a network device sends configuration information of a synchronization block (Synchronization Signal / PBCH Block, SSB), and then periodically sends the SSB according to the SSB configuration information. A terminal can periodically receive the SSB according to the SSB configuration information, and perform cell search, timing and frequency synchronization, and location and mobility management according to the SSB. The SSB configuration information can be carried in SIB1 or RRC. For example, in a carrier aggregation (Carrier Aggregation, CA) scenario, the SSB configuration information of a primary cell (Primary Cell, PCell) can be carried in a system information block 1 (System Information Block 1, SIB1), and the SSB configuration information of a secondary cell (Secondary Cell, SCell) can be carried in radio resource control (Radio Resource Control, RRC) signaling.

[0156] In the above related art, the network device periodically sends the SSB, and the terminal periodically receives the SSB, which causes large power consumption of the network device and the terminal.

[0157] In view of this, the embodiments of the present disclosure provide a synchronization block transmission method and device. In the method, the network device dynamically adjusts SSB transmission, for example, can send the SSB in the case of needing to send the SSB, and cancel sending the SSB in the case of not needing to send the SSB. The method and the device are implemented according to the same application concept. Since the principles of the method and the device for solving problems are similar, the implementation of the device and the method can be mutually referred to, and the repeated parts will not be described again.

[0158] The technical solutions in the embodiments of the present disclosure will be described clearly and completely below with reference to the drawings in the embodiments of the present disclosure. Obviously, the described embodiments are only part of the embodiments of the present disclosure, and not all embodiments. According to the embodiments in the present disclosure, all other embodiments obtained by those skilled in the art without creative labor are within the scope of protection of the present disclosure.

[0160] S101, the network device sends first signaling to the first terminal, and the first signaling indicates the start of transmission of the SSB of at least one SCell. Correspondingly, the first terminal receives the first signaling.

[0161] The first signaling can also be indicated in the following manner 11 and manner 12.

[0162] Manner 11, the first signaling indicates the end of SSB transmission of at least one SCell.

[0163] In the embodiments of the present disclosure, "end" can be understood as stopping or ending, and "stop" can be understood as stopping or ending.

[0164] Manner 12, the first signaling indicates the start of SSB transmission of a part of SCells and indicates the end of SSB transmission of another part of SCells.

[0165] In an optional implementation, the first signaling can be any one of the following: RRC signaling, Medium Access Control Control Element (MAC CE) signaling, and Downlink Control Information (DCI) signaling.

[0166] S102, for each SCell, the network device sends, to the first terminal, the SCell corresponding SSB according to the first signaling.

[0167] Correspondingly, for each SCell, the first terminal receives the SCell corresponding SSB according to the first signaling.

[0168] On the basis of manner 11, the network device cancels sending the SCell corresponding SSB to the first terminal according to the first signaling. Correspondingly, the terminal cancels receiving the SCell corresponding SSB according to the first signaling.

[0169] On the basis of manner 12, the network device sends, to the first terminal, the SCell corresponding SSB according to the first signaling, and cancels sending the SCell corresponding SSB. Correspondingly, the terminal receives the SCell corresponding SSB according to the first signaling, and cancels receiving the SCell corresponding SSB.

[0170] In the embodiments of the present disclosure, the network device sends the first signaling to the first terminal, and sends the SCell corresponding SSB to the first terminal according to the first signaling, wherein the first signaling indicates the start of SSB transmission of at least one SCell, which can realize the need to send SSB, without the network device periodically sending SSB and the terminal periodically receiving SSB, thereby reducing the energy consumption of the network device and the first terminal.

[0171] In an optional implementation, the first signaling includes one or more of the following:

[0172] The first indication information is used to indicate the start of SSB transmission of at least one SCell and / or activate at least one SCell;

[0173] a configuration index or a parameter index corresponding to the SCell, used to indicate SSB configuration information or parameter values corresponding to the SCell;

[0174] SSB configuration information or parameter values corresponding to the SCell, used to configure parameters of the SSB;

[0175] a parameter adjustment identifier of the SSB corresponding to the SCell, used to indicate adjustment of parameters of the SSB;

[0176] second indication information, used to indicate SSB transmission enabling;

[0179] fifth indication information, used to indicate SSB transmission enabling or SSB adaptive parameter adjustment enabling;

[0180] at least one SCell indication field corresponding to at least one SCell, the SCell indication field being used to indicate one or more of the following for the corresponding SCell: SSB transmission start, SSB adaptive parameter adjustment, SSB adaptive parameter not adjustment, SCell activation, SCell deactivation.

[0181] Optionally, the parameters of the SSB include one or more of the following: periodicity, frequency location, power, SSB position in burst, transmission time.

[0182] Optionally, in a case where the network device has pre-configured multiple sets of SSB configuration information or parameter values for the SCell for the first terminal, the configuration index or the parameter index corresponding to the SCell can indicate one set of SSB configuration information or parameter values from the multiple sets of SSB configuration information or parameter values.

[0183] Optionally, the parameter adjustment identifier may, for example, indicate adjustment of one or more of the following for the SSB: periodicity, frequency location, SSB position in burst, transmission time.

[0184] For example, in a case where the parameter adjustment identifier indicates adjustment of the periodicity of the SSB, if the network device is transmitting the SSB of the SCell before sending the first signaling, the network device can adjust the periodicity of the SSB according to the parameter adjustment identifier, and transmit the SSB according to the adjusted periodicity after sending the first signaling.

[0185] The following takes the first signaling as an example of RRC signaling, MAC CE signaling, or DCI signaling to illustrate the relationship between the first signaling and the SCell.

[0186] Mode 21, the first signaling is RRC signaling, and one first signaling is used to indicate the transmission start of the SSB of one SCell and / or activate the SCell.

[0187] Optionally, the first signaling in mode 21 can include first indication information. Optionally, in the case where the network device configures a set of SSB configuration information or parameter values corresponding to the SCell, the first signaling can also include the set of SSB configuration information or parameter values. Optionally, in the case where the network device configures multiple sets of SSB configuration information or parameter values corresponding to the SCell, the first signaling can also include a configuration index or a parameter index corresponding to the SCell.

[0188] Mode 22, the first signaling is RRC signaling, and one first signaling is used to indicate the transmission start of the SSB of multiple SCells and / or activate the multiple SCells.

[0189] Optionally, the first signaling in mode 22 can include a first list, and the first list includes first indication information of multiple SCells. The first indication information is, for example, an identifier (such as an index) of the SCell, which is used to indicate the transmission start of the SSB of the SCell and / or activate the SCell.

[0190] Optionally, the first signaling in mode 22 can include first indication information and a first list, and the first list includes identifiers (such as indexes) of multiple SCells, and the first indication information is used to indicate the transmission start of the SSB of the multiple SCells, and the identifier is used to indicate the SCell.

[0191] It should be noted that the first list can be located in the configuration corresponding to the Pcell in the first signaling; or the first list can be located in the configuration corresponding to a certain SCell in the first signaling; or the first list is independent of the configuration corresponding to the Pcell and the configuration corresponding to the SCell, and is set as an independent parameter in the first signaling.

[0192] Optionally, in the case where the network device does not pre-configure a set of SSB configuration information or parameter values corresponding to each SCell for the first terminal, the first signaling can also include a set of SSB configuration information or parameter values corresponding to each SCell.

[0193] Optionally, in the case that the network device pre-configures multiple sets of SSB configuration information or parameter values corresponding to each SCell for the first terminal, the first signaling can further include a configuration index or a parameter index corresponding to each SCell.

[0194] Optionally, in the case that the first signaling is used to indicate the start of transmission and / or activation of the SSB of at least one SCell, the first signaling can further include at least one first reference identifier, the at least one first reference identifier being used to determine the at least one SCell and indicating the start of transmission and / or activation of the SSB of the at least one SCell.

[0195] The first reference identifier is used to indicate one SCell.

[0196] In this case, the network device needs to configure a corresponding reference identifier for each SCell. For example, the network device configures the reference identifier for each SCell as shown in Table 1 below.

[0197] Table 1

[0198] Based on Table 1, the first reference identifier for SCell 2 indicates that the transmission of the SSB of SCell 1-6 is referenced to the transmission of the SSB of SCell 2.

[0199] In the case that the first signaling includes at least one first reference identifier, when the network device does not pre-configure SSB configuration information or parameter values for the first terminal, the first signaling can further include SSB configuration information or parameter values corresponding to each SCell; when the network device pre-configures multiple sets of SSB configuration information or parameter values for the first terminal, the first signaling can further include a configuration index or a parameter index corresponding to each SCell.

[0200] Optionally, the first signaling of mode 21 and mode 22 can not include SSB configuration information or parameter values, in which case, the SSB configuration information or parameter values can be carried in another RRC signaling. For example, multiple sets of SSB configuration information or parameter values carried in the RRC signaling are configured as follows (ODSSBConfig):

[0201] ODSSBConfig::=SEQUENCE{

[0202] SSB configuration information or parameter value-1 (Config-1)

[0203] {periodicity 5ms

[0204] SSBPositioninBurst 8bit

[0205] Transmission time N 3}

[0206] SSB configuration information or parameter value-2 (Config-2)

[0207] {periodicity 20ms

[0208] SSBPositioninBurst 8bit

[0209] Transmission time N 5}。

[0210] Option 23, the first signaling is MAC CE signaling, and one first signaling is used to indicate the transmission start of the SSB of multiple SCells and / or activate the SCell.

[0211] The information carried in the first signaling in option 23 is described below in combination with FIG. 2.

[0212] FIG. 2 is an example diagram of one indication of the MAC CE signaling provided in an embodiment of the present disclosure. As shown in FIG. 2, the MAC CE signaling includes a 2 / 2A field, an indication field, and an SSB Config ID field.

[0213] The 2 / 2A field is first indication information. For example, when the first indication information is 0, it indicates that the MAC CE signaling is used to indicate the transmission start or end of the SSB, when the first indication information is 1, it indicates that the MAC CE signaling is used to indicate the transmission start of the SSB and activate the SCell, or it indicates that the MAC CE signaling is used to indicate the transmission end of the SSB and / or deactivate the SCell.

[0214] Optionally, the 2 / 2A field can also be independently configured for each SCell. The 31 SCells in the figure can include 31 2 / 2A fields.

[0215] The indication field includes Ci corresponding to 31 SCells, where i is an integer between 1 and 31.

[0216] Optionally, Ci=0 or Ci=1.

[0217] When the first indication information is 0, Ci=1 indicates the transmission start of the SSB of SCell i, and Ci=0 indicates the transmission end of the SSB of SCell i.

[0218] When the first indication information is 1, Ci = 1 indicates that the transmission of the SSB of the SCell i starts and activates the SCell i, and Ci = 0 indicates that the transmission of the SSB of the SCell i ends and / or deactivates the SCell i.

[0219] The 31 configuration indexes or parameter indexes corresponding to the SCells are included in the SSB Config ID field. It should be noted that in the case where the network device configures multiple sets of SSB configuration information or parameter values corresponding to each SCell for the first terminal, the SSB Config ID field can be included in the MAC CE signaling.

[0220] Optionally, the SSB Config ID field can be replaced by an SSB position in burst, and the SSB position in burst is used to indicate the beam of the SSB of each SCell, which is the SCell transmitting the SSB.

[0221] Optionally, the SSB Config ID field can be replaced by a 2 / 2A field, and in this case, the 2 / 2A field does not exist.

[0222] It should be noted that when the first signaling is MAC-CE signaling, the MAC-CE signaling can be transmitted on the physical downlink shared channel (PDSCH) resource scheduled by DCI 1_0 for receiving a random access response (RAR), or on the resource where the SIB1 is located, so that all terminals in the SCell can receive the MAC-CE signaling at the same time.

[0223] FIG. 3 is an example diagram of one indication of the MAC CE signaling provided by the embodiment of the present disclosure. As an example, as shown in FIG. 3, the MAC CE signaling includes: an on-demand SSB transmission / stop transmission indication field, an on-demand SSB indication enabling field, an SCell activation / deactivation indication field, and an SCell activation / deactivation enabling field.

[0224] As an example, the End-SSB in FIG. 3 represents the on-demand SSB indication enabling field. The second indication information is set on the on-demand SSB indication enabling field. For example, the value of the second indication information is 1, indicating that the on-demand SSB transmission / stop transmission indication field is valid (i.e., the second indication information indicates that the SSB transmission is enabled). For example, the value of the second indication information is 0, indicating that the on-demand SSB transmission / stop transmission indication field is invalid (i.e., the second indication information indicates that the SSB transmission is not enabled).

[0225] Exemplarily, 31 SCell indication fields corresponding to 31 SCells are included in the on-demand SSB transmission / stop transmission indication field. The sixth indication information (Ci) is set on the i-th SCell indication field, where Ci indicates the start or end of SSB transmission of SCell i, and i takes an integer between 1 and 31. Optionally, Ci = 0 or Ci = 1.

[0226] Exemplarily, when the value of the second indication information is 1, Ci = 1 indicates the start of SSB transmission of SCell i, and Ci = 0 indicates the end of SSB transmission of SCell i. When the value of the second indication information is 0, the value of Ci is meaningless.

[0227] Exemplarily, the End-SCell in FIG. 3 represents an SCell activation / deactivation enabling field. The third indication information is set on the SCell activation / deactivation enabling field. For example, the value of the third indication information is 1, representing that the SCell activation / deactivation indication field is valid (i.e., the third indication information indicates SCell activation enabling). For example, the value of the third indication information is 0, representing that the SCell activation / deactivation indication field is invalid (i.e., the third indication information indicates SCell deactivation enabling).

[0228] Exemplarily, 31 SCell indication fields corresponding to 31 SCells are included in the SCell activation / deactivation indication field. Ci is set on the i-th SCell indication field, where Ci indicates the activation or deactivation of SCell i, and i takes an integer between 1 and 31. Optionally, Ci = 0 or Ci = 1.

[0229] Exemplarily, when the value of the third indication information is 1, Ci = 1 indicates the activation of SCell i, and Ci = 0 indicates the deactivation of SCell i. When the value of the third indication information is 0, the value of Ci is meaningless.

[0230] Optionally, the MAC CE shown in FIG. 3 can also not include the on-demand SSB indication enabling field, or not include the SCell activation / deactivation enabling field, or not include the on-demand SSB indication enabling field and the SCell activation / deactivation enabling field.

[0231] Optionally, in the case that the network device configures multiple sets of SSB configuration information or parameter values corresponding to each SCell for the first terminal, the MAC CE signaling can further include an SSB Config ID field. The SSB Config ID field is similar to that in FIG. 2, which will not be described herein again. Optionally, in the case that the MAC CE signaling further includes the SSB Config ID field, the SSB Config ID field can be replaced by an SSB position in burst, which is used to indicate the beam of the SSB of each SCell. Here, the SCell is the SCell that transmits the SSB.

[0232] Optionally, the MAC-CE can further include an SSB adaptive parameter adjustment enabling field and an SSB adaptive parameter adjustment indication field. The case is described below in combination with FIG. 4.

[0233] FIG. 4 is an example diagram of one indication of the MAC CE signaling provided by an embodiment of the present disclosure. Exemplarily, as shown in FIG. 4, the MAC CE signaling further includes an SSB adaptive parameter adjustment enabling field and an SSB adaptive parameter adjustment indication field on the basis of FIG. 3.

[0234] Exemplarily, in FIG. 4, Enb_ASSB represents the SSB adaptive parameter adjustment enabling field. The fourth indication information is set on the SSB adaptive parameter adjustment enabling field. For example, the fourth indication information has a value of 1, indicating that the SSB adaptive parameter adjustment indication field is valid (i.e., the fourth indication information indicates that the SSB adaptive parameter adjustment is enabled). For example, the fourth indication information has a value of 0, indicating that the SSB adaptive parameter adjustment indication field is invalid (i.e., the fourth indication information indicates that the SSB adaptive parameter adjustment is not enabled).

[0235] Exemplarily, the SSB adaptive parameter adjustment indication field can include SCell indication fields corresponding to 31 SCells. Ci is set on the i-th SCell indication field, where Ci indicates the SSB adaptive parameter adjustment of SCell i or the SSB adaptive parameter adjustment is not adjusted, and i has a value of an integer between 1 and 31. Optionally, Ci = 0 or Ci = 1.

[0236] Exemplarily, when the value of the fourth indication information is 1, Ci = 1 indicates the SSB adaptive parameter adjustment of SCell i, such as a change period, or indicates that the SSB of SCell i is transmitted according to the period corresponding to configuration information 1; Ci = 0 indicates that the SSB adaptive parameter adjustment of SCell i is not adjusted (i.e., the transmission mode of the SSB remains unchanged), or indicates that the SSB is transmitted according to the period corresponding to configuration information 2.

[0237] Exemplarily, when the fourth indication information is 0, the value of Ci is meaningless.

[0238] In some embodiments, the MAC-CE can further include a selection enabling field. The number of bits occupied by the selection enabling field can be 1 or more.

[0239] The following takes the number of bits occupied by the selection enabling field as 2 as an example, and the MAC-CE signaling is described in combination with FIG. 5.

[0240] FIG. 5 is an example diagram four of the MAC-CE signaling provided by the embodiment of the present disclosure. Exemplarily, as shown in FIG. 5, the MAC-CE signaling further includes a selection enabling field (which can also be referred to as an on-demand SSB indication / SSB adaptive parameter adjustment selection enabling field), a selection indication field, an SCell activation / deactivation enabling field, and an SCell activation / deactivation indication field.

[0241] Exemplarily, in FIG. 5, the End-SSB / Enb_ASSB / Enb represents the selection enabling field. The selection enabling field can indicate SSB transmission enabling (that is, on-demand SSB transmission / stop transmission enabling), SSB adaptive parameter adjustment enabling, or none of the above. Wherein, none of the above means that neither SSB transmission enabling nor SSB adaptive parameter adjustment is enabled.

[0242] The fifth indication information can be set in the selection enabling field. The number of bits of the fifth indication information is 2.

[0243] Exemplarily, the value of the fifth indication information is 00, which is used to indicate SSB transmission enabling. At this time, the selection indication field can be an on-demand SSB transmission / stop transmission indication field, which is used to indicate the start or stop of transmission of the SSB of the SCell. The explanation and description of the on-demand SSB transmission / stop transmission indication field can be referred to the embodiment of FIG. 3, which will not be described here.

[0244] Exemplarily, the value of the fifth indication information is 01, which is used to indicate SSB adaptive parameter adjustment enabling. At this time, the selection indication field can be an SSB adaptive parameter adjustment indication field, which is used to indicate SSB adaptive parameter adjustment of the SCell. The explanation and description of the SSB adaptive parameter adjustment indication field can be referred to the embodiment of FIG. 4, which will not be described here.

[0245] Exemplarily, the value of the fifth indication information is 10, which is used to indicate none of the above. At this time, the value of Ci of the selection indication field is meaningless.

[0246] Exemplarily, in FIG. 5, the End-Scell represents the SCell activation / deactivation enabling field. It should be noted that the explanation of the SCell activation / deactivation enabling field and the SCell activation / deactivation indication field shown in FIG. 5 can refer to the embodiment of FIG. 3, and will not be repeated here.

[0247] In some embodiments, exemplarily, the value of the fifth indication information is 00, which can represent SSB transmission enabling, the value of the fifth indication information is 01, which can represent SSB adaptive parameter adjustment enabling, and the value of the fifth indication information is 01, which can represent SCell activation enabling field.

[0248] Optionally, the MAC-CE can also not have the SCell activation / deactivation indication field. The following takes the number of bits occupied by the selection enabling field as 1 as an example, and the MAC CE signaling is explained in combination with FIG. 6.

[0249] FIG. 6 is an example diagram of one indication of the MAC CE signaling provided by the embodiment of the present disclosure. Exemplarily, as shown in FIG. 6, the MAC CE signaling includes: a selection enabling field and a selection indication field.

[0250] Exemplarily, the End-SSB / Enb_ASSB represents the selection enabling field.

[0251] The selection enabling field can be SSB transmission enabling or SSB adaptive parameter adjustment enabling.

[0252] The fifth indication information can be set in the selection enabling field.

[0253] Exemplarily, the value of the fifth indication information is 0 (i.e. 1 bit), which represents SSB transmission enabling. At this time, the selection indication field can be an on-demand SSB transmission / stop transmission indication field, which is used to indicate the start of transmission or the end of transmission of the SSB of the SCell. The explanation of the on-demand SSB transmission / stop transmission indication field can refer to the embodiment of FIG. 3, and will not be repeated here.

[0254] Exemplarily, the value of the fifth indication information is 1 (i.e. 1 bit), which represents SSB adaptive parameter adjustment enabling. At this time, the selection indication field can be an SSB adaptive parameter adjustment indication field, which is used to indicate the SSB adaptive parameter adjustment of the SCell. The explanation of the SSB adaptive parameter adjustment indication field can refer to the embodiment of FIG. 4, and will not be repeated here.

[0255] On the basis of the above-mentioned FIG. 3 to FIG. 6, the person skilled in the art can increase, decrease, exchange, etc. the fields of the MAC CE signaling in FIG. 3 to FIG. 6, and the new MAC CE signaling obtained is within the protection scope of the present disclosure.

[0256] In mode 24, the first signaling is DCI signaling, and one first signaling is used to indicate the transmission start of the SSB of at least one SCell and / or the parameter adjustment (for example, adaptive parameter adjustment) of the SSB. The DCI signaling may, for example, be DCI format 2-X. Optionally, X may be equal to 15.

[0257] The information carried in the first signaling in mode 24 is described below in combination with FIG. 7.

[0258] FIG. 7 is an example diagram of one indication of DCI signaling provided by an embodiment of the present disclosure. As shown in FIG. 7, the DCI signaling includes an R field and an indication field.

[0259] The R field may be used to carry first indication information, which indicates the transmission indication of the SSB of at least one SCell or indicates the parameter adjustment of the SSB of the SCell.

[0260] In a case where the network device pre-configures a set of SSB configuration information corresponding to each SCell for the first terminal, the DCI signaling shown in FIG. 7 may be 32 bits (bit).

[0261] The R field is 1 bit, and the value of the 1-bit is 1, which may indicate that the DCI signaling is used to indicate whether the SCell transmits the SSB, and the value of the 1-bit is 0, which may indicate that the DCI signaling is used to adjust the parameter of the SSB of the SCell.

[0262] The indication field includes 31 subfields, each of which is 1 bit, and Ci in the subfield corresponds to SCell i (that is, the SCell with index i), where i is an integer between 1 and 31.

[0263] Optionally, when the value of the 1-bit of the R field is 1, Ci=1 indicates that the SSB on SCell i starts to transmit, and Ci=0 indicates that the SSB transmission on SCell i ends.

[0264] Optionally, when the value of the 1-bit of the R field is 0, Ci=1 indicates that the SSB on SCell i uses parameter 1 for transmission, and Ci=0 indicates that the SSB on SCell i uses parameter 2 for transmission. Parameter 1 may be the period of the SSB, and the value of parameter 1 is 20 ms, and parameter 2 may be the period of the SSB, and the value of parameter 2 is 40 ms.

[0265] In a case where the network device pre-configures a set of SSB configuration information corresponding to each SCell for the first terminal, the DCI signaling shown in FIG. 7 may be greater than 32 bits.

[0266] Wherein, the R field is 1 bit, and the value of the 1 bit is 1, which indicates that the transmission of the SSB of the SCell starts, and the value of the 1 bit is 1, which indicates that the parameter of the SSB of the SCell is adjusted.

[0267] Wherein, the indication field includes 31 subfields (for example, C1 to C31), and each subfield includes N+1 bits, and the N bits in the subfield are used to indicate the configuration index or parameter index corresponding to the SCell, and the 1 bit in the subfield is the same as the description of the aforementioned 1 bit.

[0268] Optionally, when the value of the 1 bit of the R field is 1, the value of the 1 bit in the subfield is 1, which indicates that the transmission of the SSB of the SCell starts, and the value of the 1 bit in the subfield is 0, which indicates that the transmission of the SSB of the SCell ends.

[0269] Optionally, when the value of the 1 bit of the R field is 0, the value of the 1 bit in the subfield is 1, which indicates that the SSB on the SCell i is transmitted using parameter 1, and the value of the 1 bit in the subfield is 0, which indicates that the SSB on the SCell i is transmitted using parameter 2.

[0270] Optionally, the number of bits of the DCI signaling can not be fixed.

[0271] Optionally, specifically, the number of bits of the DCI signaling can be determined according to the number of SCells of which the RRC signaling is configured to always transmit (always-on) SSBs.

[0272] Optionally, the DCI signaling further includes a physical cell identifier (PCI) corresponding to the SCell. For example, when C10=1, the DCI signaling further includes the PCI corresponding to the SCell corresponding to C10.

[0273] Optionally, Ci in the DCI signaling corresponds to the CC corresponding to the i-th PCI in the PCI list configured by the network device.

[0274] For example, the PCI list is {PCI i, i is an integer between 1 and 31}, and Ci=1 indicates that the SSB is transmitted on the CC where the PCI i is located or the parameter of the SSB is adjusted.

[0275] Optionally, the DCI signaling can be monitored through a configured common resource set (CORESET) and a search space (search space) to ensure that all terminals in the SCell can simultaneously receive the DCI signaling.

[0276] In an optional implementation, S102 specifically comprises: at a first preconfigured time after sending the first signaling, sending, according to the first signaling, the SSB corresponding to the SCell to the first terminal. Correspondingly, at the first preconfigured time after receiving the first signaling, the first terminal receives, according to the first signaling, the SSB corresponding to the SCell sent by the network device.

[0277] In an optional implementation, the first preconfigured time is determined according to one or more of the following:

[0278] the device capability information of the first terminal;

[0279] the type of the SCell, the type indicating whether the frequency point of the SCell is the same as or different from the primary cell (PCell) of the terminal

[0280] a system pre-defined sending time;

[0281] a pre-defined duration;

[0282] a first duration.

[0283] Optionally, the first duration can be one of a plurality of candidate durations. Optionally, the plurality of candidate durations can be system pre-defined durations, or candidate durations sent by the first terminal to the network device according to the device capability information of the first terminal. Optionally, in the case where the first terminal sends the plurality of candidate durations to the network device, the first terminal sends the plurality of candidate durations with the (sub-carrier space, SCS) of the PCell as a reference.

[0284] Optionally, the first preconfigured time is determined according to the device capability information of the first terminal.

[0285] Optionally, the network device and the first terminal can determine, as the first preconfigured time, the preconfigured time corresponding to the device capability information of the first terminal in a first correspondence relationship. The first correspondence relationship includes a correspondence relationship between a plurality of device capability information and a plurality of preconfigured times.

[0286] Optionally, the first preconfigured time is determined according to the device capability information of the first terminal and the type of the SCell.

[0287] Optionally, the first preconfigured time is determined according to a system pre-defined sending time.

[0288] Optionally, the network device can determine, as the first preconfigured time, the system pre-defined sending time.

[0289] Optionally, the first preconfigured time is determined according to a system pre-defined sending time and a pre-defined duration.

[0290] Optionally, the sum of the sending time of the system predefinition and the predefined duration is determined as the first preconfigured time.

[0291] In mode 35, the first preconfigured time is determined according to the sending time of the first signaling and the first duration.

[0292] Optionally, the network device and the first terminal can determine the sum of the sending time of the first signaling and the first duration as the first preconfigured time.

[0293] In mode 36, the first preconfigured time is determined according to the first duration and the type of the SCell.

[0294] The network device and the first terminal can determine the first duration from among multiple candidate durations according to the device capability information of the first terminal and the type of the SCell,

[0295] In mode 37, the first preconfigured time is determined according to the sending time of the first signaling and a predefined duration

[0296] Optionally, the network device and the first terminal can determine the sum of the sending time of the first signaling and the predefined duration as the first preconfigured time.

[0297] Optionally, the network device can determine the first duration corresponding to each SCell. Optionally, the first durations corresponding to multiple SCeils determined by the network device need to be able to guarantee that the SSBs of the multiple SCeils are transmitted at the same time.

[0298] Optionally, the unit of the first duration can be OFDM symbols. When the subcarrier spacings SCSs are different, the network device needs to perform conversion to obtain the number of OFDM symbols in different SCSs and perform configuration.

[0299] Optionally, the first preconfigured time can be a certain SSB transmission occasion after the first duration. The certain SSB transmission occasion is, for example, the first candidate SSB transmission occasion.

[0300] Optionally, the first preconfigured time can be a time located in a preset period. The preset period can be an integer multiple of the SSB period.

[0301] The network device can transmit the SSB of the SCell at the first preconfigured time in the preset period, and the first terminal can receive the SSB of the SCell at the first preconfigured time in the first preset period after receiving the first signaling.

[0302] On the basis of the above embodiments, the synchronization block transmission method provided by the embodiments of the present disclosure is further described below in combination with FIG. 8.

[0303] FIG. 8 is a flowchart of a method for transmitting a synchronization block according to an embodiment of the present disclosure. As shown in FIG. 8, the method includes the following steps.

[0304] S801, the network device sends first signaling to the first terminal, the first signaling indicating transmission start of SSBs of at least one SCell. Correspondingly, the first terminal receives the first signaling.

[0305] The first signaling includes one or more of the following:

[0306] First indication information, used for indicating transmission start of SSBs of the at least one SCell and / or activating the at least one SCell;

[0307] A configuration index or a parameter index corresponding to the SCell, used for indicating SSB configuration information or parameter values corresponding to the SCell;

[0308] SSB configuration information or parameter values corresponding to the SCell, used for configuring parameters of the SSBs;

[0309] A parameter adjustment identifier of the SSBs corresponding to the SCell, used for indicating adjustment of parameters of the SSBs;

[0310] Second indication information, used for indicating SSB transmission enablement;

[0311] Third indication information, used for indicating SCell activation enablement or SCell deactivation enablement;

[0312] Fourth indication information, used for indicating SSB adaptive parameter adjustment enablement or SSB adaptive parameter adjustment disablement;

[0313] Fifth indication information, used for indicating SSB transmission enablement or SSB adaptive parameter adjustment enablement;

[0314] At least one SCell indication field corresponding to the at least one SCell, the SCell indication field being used for indicating one or more of the following for the corresponding SCell: SSB transmission start, SSB adaptive parameter adjustment, SSB adaptive parameter non-adjustment, SCell activation, SCell deactivation.

[0315] S802, for each SCell, the network device sends SSBs corresponding to the SCell to the first terminal according to the first signaling.

[0316] S803, the network device sends second signaling to the first terminal, the second signaling indicating transmission start of SSBs of at least one SCell.

[0317] The second signaling can be any one of the following: RRC signaling, MAC CE signaling, and DCI signaling.

[0318] Optionally, the first signaling and the second signaling can be same signaling or different signaling.

[0319] Optionally, information included in the first signaling and the second signaling can be same or different.

[0320] S804a, the network device sends, according to the second signaling, the SSB corresponding to the SCell to the first terminal.

[0321] Correspondingly, the first terminal receives the SSB corresponding to the SCell according to the second signaling.

[0322] It should be noted that the SCell in S803 can be same or different from the SCell in S804a-S804c.

[0323] In the embodiments of the present disclosure, the network device can send, according to the second signaling, the SSB corresponding to the SCell to the first terminal at a second preconfigured time after sending the second signaling. Correspondingly, the first terminal receives the SSB corresponding to the SCell according to the second signaling at the second preconfigured time.

[0324] The second preconfigured time is determined in a similar manner to the first preconfigured time, which will not be described here.

[0325] S804a can be an implementation of deactivation between the same signaling.

[0326] For example, in the case that the first signaling and the second signaling sent by the network device successively are MAC-CE signaling, the second signaling can deactivate the first signaling, that is, the network device sends, according to the second signaling, the SSB corresponding to the SCell to the first terminal.

[0327] For example, if the first signaling indicates the start of SSB transmission of SCell 1, and the second signaling indicates the end of SSB transmission of SCell 1, the network device suspends the transmission of SSB of SCell 1. Or, if the first signaling indicates the start of SSB transmission of SCell 1, and the second signaling indicates the start of SSB transmission of SCell 1, the network device suspends the SSB transmission of SCell 1 indicated in the first signaling when sending the second signaling. And restart the SSB transmission of SCell 1 according to the indication of the second signaling.

[0328] Optionally, in the case that the first signaling and the second signaling sent by the network device in succession are both MAC-CE signaling, if the first signaling indicates that the SSB transmission of the SCell 1 starts, the first terminal receives the second signaling within the first time length, and the second signaling indicates that the SSB transmission of the SCell 1 starts, the first terminal can start sending the SSB of the SCell 1 according to the second signaling after the first time length from the sending time of the second signaling.

[0329] S804b, the network device sends the SSB corresponding to the SCell to the first terminal according to the first signaling when the information included in the first signaling and the second signaling is the same.

[0330] Optionally, in the case that the first signaling and the second signaling sent by the network device in succession are both MAC-CE signaling, if the first signaling indicates that the SSB transmission of the SCell 1 starts, the second signaling indicates that the SSB transmission of the SCell 1 starts, the network device continues to send the SSB of the SCell 1 indicated by the first signaling, which is not affected by the indication of the second signaling.

[0331] It should be noted that the time at which the network device sends the SSB corresponding to the SCell to the first terminal according to the first signaling is not affected by the sending time of the second signaling.

[0332] S804c, the network device sends the SSB corresponding to the SCell to the first terminal according to the second signaling when the information included in the first signaling and the second signaling is not the same, or the priority of the first signaling is lower than the priority of the second signaling.

[0333] Correspondingly, the first terminal receives the SSB corresponding to the SCell according to the second signaling.

[0334] The priority order of the RRC signaling, the MAC CE signaling and the DCI signaling is, for example, RRC signaling, MAC CE signaling, DCI signaling, from low to high. In the case that the first signaling is RRC signaling and the second signaling is DCI signaling, the SSB corresponding to the SCell is sent to the first terminal according to the second signaling.

[0335] It should be noted that S804a-S804c in the embodiment of FIG. 8 are methods executed in different cases. The network device can execute any one of S804a-S804c.

[0336] FIG. 9 is a third flowchart of a method for transmitting a synchronization block according to an embodiment of the present disclosure. As shown in FIG. 9, the method comprises:

[0337] S901, the network device sends a first signaling to the first terminal, and the first signaling indicates the start of the SSB transmission of at least one SCell. Correspondingly, the first terminal receives the first signaling.

[0338] S902, for each SCell, the network device sends, according to the first signaling, an SSB corresponding to the SCell to the first terminal.

[0339] S903, for each SCell, the network device sends, to terminals other than the first terminal in the SCell, third signaling, the third signaling being used to indicate a transmission start of an SSB of the SCell.

[0340] The other terminals can receive the SSB of the SCell according to the third signaling.

[0341] The third signaling may, for example, be any one of the following: RRC signaling, MAC CE signaling, DCI signaling, and system message. The system message may, for example, be SIB1.

[0342] Optionally, the first signaling and the third signaling can be the same signaling. For example, the first signaling and the third signaling are both RRC signaling.

[0343] Optionally, the third signaling and the first signaling can include the same information.

[0344] Optionally, the third signaling can also only include an identification of the SCell.

[0345] Optionally, the third signaling includes a PCI of the SCell that transmits the SSB.

[0346] FIG. 10 is a fourth flowchart of a synchronization block transmission method according to an embodiment of the present disclosure. As shown in FIG. 10, the method includes:

[0347] S1001, the network device sends, to a plurality of terminals including a first terminal, first signaling on a same time-frequency resource and frequency domain resource of the plurality of terminals, the first signaling indicating a transmission start of a synchronization block SSB of at least one secondary cell SCell.

[0348] Correspondingly, each terminal receives the first signaling on the same time-frequency resource and frequency domain resource of the plurality of terminals.

[0349] Optionally, the first signaling can be MAC CE signaling or DCI signaling.

[0350] Optionally, the first signaling can also be RRC signaling.

[0351] S1002, for each SCell, the network device sends, according to the first signaling, an SSB corresponding to the SCell to the plurality of terminals.

[0352] Correspondingly, each terminal receives the SSB corresponding to the SCell according to the first signaling.

[0353] It should be noted that in the embodiment of FIG. 10, the network can also send the second signaling to the plurality of terminals on the same time-frequency resources and frequency domain resources of the plurality of terminals.

[0354] The embodiments of the present disclosure further provide four manners for stopping transmission of the SSB corresponding to the SCell.

[0355] In manner 41, the network device sends fourth signaling to the first terminal, the fourth signaling being used to indicate stopping transmission of the SSB corresponding to the SCell; and the network device stops sending the SSB corresponding to the SCell to the first terminal in a case where the network device receives first feedback signaling corresponding to the fourth signaling sent by the first terminal.

[0356] Correspondingly, the first terminal receives the fourth signaling sent by the network device; stops receiving the SSB corresponding to the SCell sent by the network device according to the fourth signaling, and sends first feedback signaling corresponding to the fourth signaling to the network device.

[0357] Optionally, the fourth signaling can also be MAC CE signaling.

[0358] The structure of the fourth signaling can be the same as that of the first signaling, or can be different.

[0359] For example, in a case where the structure of the fourth signaling is as shown in FIG. 6, when the fifth indication information in the selection enabling field is 0 (indicating SSB transmission enabling) and Ci corresponding to SCell i in the selection indication field is 0 (indicating transmission of the SSB of SCell i is ended), the first terminal sends first feedback signaling corresponding to the fourth signaling to the network device after receiving the fourth signaling. The first feedback signaling indicates that the indication of the transmission of the SSB corresponding to SCell i is correctly received.

[0360] In some embodiments, if the network device does not receive the first feedback signaling, it is still required to maintain the SSB transmission of SCell i. If the network device stops sending the SSB of SCell i, it will cause the first terminal to fail to detect the SSB, and can cause link failure.

[0361] In a case where the network device does not receive the first feedback signaling, the network device continues to send the fourth signaling to the first terminal until the first feedback signaling sent by the first terminal is received.

[0362] In some embodiments, after the network device receives the first feedback signaling sent by the first terminal, the stopping moment of the SSB transmission corresponding to the SCell can be determined according to a time offset indicated by system convention or configuration, and the SSB corresponding to the SCell is stopped at the stopping moment.

[0363] The first feedback signaling is, for example, Hybrid Automatic Repeat-reQuest Acknowledgement (HARQ-ACK) signaling.

[0364] In mode 42, the network device sends fifth signaling to the first terminal, the fifth signaling being used to adaptively adjust parameters of the SSB corresponding to the SCell; and the network device stops sending the SSB corresponding to the SCell to the first terminal. Correspondingly, the first terminal receives the fifth signaling sent by the network device, and stops receiving the SSB corresponding to the SCell sent by the network device after receiving the fifth signaling.

[0365] Optionally, the fifth signaling can be MAC CE signaling or DCI signaling.

[0366] In some embodiments, after sending the fifth signaling to inform the first terminal to adjust the parameters, the network device can directly adjust the parameters of the SSB corresponding to the SCell within a certain time, and stop sending the SSB corresponding to the SCell to the first terminal within the time.

[0367] In some embodiments, after receiving the fifth signaling, the first terminal can send second feedback signaling corresponding to the fifth signaling to the network device, and the network device stops sending the SSB corresponding to the SCell to the first terminal after receiving the second feedback signaling corresponding to the fifth signaling. The second feedback signaling indicates that the indication of the adaptive parameter adjustment of the SSB has been correctly received.

[0368] The second feedback signaling is, for example, HARQ-ACK signaling.

[0369] In mode 43, the network device sends fifth signaling to the first terminal, the fifth signaling being used to adaptively adjust parameters of the SSB corresponding to the SCell; and the network device determines whether to stop sending the SSB corresponding to the SCell to the first terminal according to the fifth signaling. Correspondingly, the first terminal receives the fifth signaling sent by the network device, and determines whether to stop receiving the SSB corresponding to the SCell sent by the network device according to the fifth signaling after receiving the fifth signaling.

[0370] In some embodiments, the network device determines whether to stop sending the SSB corresponding to the SCell to the first terminal according to the content in the fifth signaling. Correspondingly, the first terminal determines whether to stop receiving the SSB corresponding to the SCell sent by the network device according to the content in the fifth signaling.

[0371] In some embodiments, the network device, in a case that the second feedback signaling corresponding to the fifth signaling is received, determines whether to stop sending the SSB corresponding to the SCell to the first terminal according to the content in the fifth signaling. Correspondingly, the first terminal, after receiving the fifth signaling, sends the second feedback signaling corresponding to the fifth signaling to the network device, and determines whether to stop receiving the SSB corresponding to the SCell sent by the network device according to the content in the fifth signaling.

[0372] For example, in a case that the fifth signaling is a MAC CE signaling, and the structure of the MAC CE signaling is as shown in FIG. 6, when the value of the fifth indication information in the selection enabling field is 1 (indicating that the SSB adaptive parameter adjustment is enabled), and Ci corresponding to SCell i in the selection indication field is 1 (indicating that the transmission period of the SSB of SCell i is changed), the first terminal, after receiving the fifth signaling, sends the second feedback signaling of the MAC-CE signaling to the network device.

[0373] For example, in a case that the content in the fifth signaling indicates that the SSB corresponding to SCell i is changed from a long period to a short period, the network device determines to stop sending the SSB corresponding to SCell i to the first terminal, and the first terminal determines to stop receiving the SSB corresponding to SCell i sent by the network device.

[0374] In some embodiments, the network device, in a case that the transmission time of the SCell is switched from the Cell DTX active time to the Cell DTX inactive time, stops sending the SSB corresponding to the SCell to the first terminal.

[0375] Correspondingly, the first terminal, in a case that the transmission time of the SCell is switched from the Cell DTX active time to the Cell DTX inactive time, stops receiving the SSB corresponding to the SCell sent by the network device.

[0376] In some embodiments, for SCell i, the network device can send, for example, a DCI format 2_9 to the first terminal, the DCI format 2_9 being used to indicate the Cell Discontinuous Transmission / Cell Discontinuous Reception (Cell DTX / DRX) activation of SCell i; in a case that the transmission time of SCell i is switched from the Cell DTX active time to the Cell DTX inactive time, the network device stops sending the SSB corresponding to SCell i to the first terminal.
