[0036] The following will be combined with the accompanying drawings in the embodiments of the present disclosure to clearly and completely describe the technical solutions in the embodiments of the present disclosure. Obviously, the embodiments described are only part of the embodiments of the present disclosure, not all of the embodiments. Based on the embodiments of the present disclosure, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present disclosure.

[0037] In the description of this disclosure, unless otherwise specified, " / " means "or". For example, A / B can mean A or B. "And / or" in this article is merely a description of the association relationship of associated objects, indicating that there can be three relationships. For example, A and / or B can mean: only A, only B, and A and B. In addition, "at least one" means one or more, and "a plurality" means two or more. Expressions such as "first" and "second" do not limit the quantity and execution order, and expressions such as "first" and "second" do not necessarily limit them to be different.

[0038] It should be noted that in this disclosure, expressions such as "exemplarily" or "for example" are used to indicate examples, illustrations, or explanations. Any embodiment or design described in this disclosure as "exemplary" or "for example" should not be construed as being preferred or advantageous over other embodiments or designs. Rather, the use of expressions such as "exemplarily" or "for example" is intended to present the relevant concepts in a detailed manner.

[0039] In some technologies, transmitting SSB on the secondary cell consumes some energy from the base station. Eliminating SSB transmission can significantly save the base station energy. However, completely eliminating SSB transmission may result in user terminals being unable to obtain synchronization information or perform automatic gain control adjustments during or after secondary cell activation. Therefore, how to transmit SSB to reduce base station energy consumption is an urgent issue.

[0040] Based on this, the present disclosure provides a signaling receiving method and a signaling sending method. In the above method, the first signaling can be used to realize on-demand transmission of SSB instead of periodic transmission. On the basis of ensuring the transmission needs of the terminal, the energy consumption of the base station can be reduced, thereby reducing the cost of the operator. Moreover, on-demand transmission of SSB can improve the flexibility of SSB transmission, thereby improving the utilization rate of network resources.

[0041] The signaling receiving method and signaling sending method provided in the present disclosure can be applied to the communication system shown in Figure 1. Figure 1 shows a schematic diagram of the architecture of a communication system provided in an embodiment of the present disclosure. As shown in Figure 1, the communication system includes a terminal 10 and a base station 20.

[0042] In some embodiments, the terminal 10 may be a device with wireless transceiver capabilities, which may be deployed on land, including indoors or outdoors, handheld, wearable, or vehicle-mounted; may also be deployed on water (such as on ships); and may also be deployed in the air (such as on airplanes, balloons, and satellites). The terminal 10 may be a mobile phone, a tablet computer, a computer with wireless transceiver capabilities, a virtual reality (VR) terminal, an augmented reality (AR) terminal, a wireless terminal in industrial control, a wireless terminal in self-driving, a wireless terminal in remote medical care, a wireless terminal in a smart grid, a wireless terminal in transportation safety, a wireless terminal in a smart city, a wireless terminal in a smart home, and the like.

[0044] It should be noted that Figure 1 is only an exemplary framework diagram. The number of devices included in Figure 1 and the names of each device are not restricted. In addition to the devices shown in Figure 1, the communication system may also include other devices (such as core network devices).

[0045] The embodiments of the present disclosure do not limit the application scenarios. The system architecture and business scenarios described in the embodiments of the present disclosure are intended to more clearly illustrate the technical solutions of the embodiments of the present disclosure and do not constitute a limitation on the technical solutions provided by the embodiments of the present disclosure. Persons skilled in the art will appreciate that with the evolution of network architecture and the emergence of new business scenarios, the technical solutions provided by the embodiments of the present disclosure are equally applicable to similar technical problems.

[0046] FIG2 is a flow chart showing a method for receiving signaling according to an embodiment of the present disclosure. As shown in FIG2 , the method for receiving signaling is applied to the terminal 10 in FIG1 and includes the following steps:

[0047] S101: Receive first signaling.

[0048] The first signaling is used to trigger the transmission of at least one synchronization signal / physical broadcast channel block SSB on at least one secondary cell.

[0049] In some embodiments, the first signaling is a secondary cell (SCell) activation signaling or a secondary cell addition signaling.

[0050] In other embodiments, the first signaling is transmitted before the secondary cell activation signaling or the secondary cell addition signaling to trigger SSB transmission on a neighboring cell or a deactivated secondary cell. In this way, the terminal can perform measurements in advance and obtain some measurement information on the cell, and the measurement information can assist the base station in selecting a secondary cell and / or reduce the secondary cell activation delay.

[0051] In some embodiments, the first signaling includes at least one of the following: radio resource control (RRC) signaling, media access control element (MAC CE), and downlink control information (DCI).

[0052] In some embodiments, the RRC signaling is a secondary cell addition signaling, which is used to add an SCell and configure the SCell state to an active state to activate the SCell.

[0053] In this way, by adding and activating SCells through RRC signaling, network coverage can be increased, network congestion can be reduced, and the user's communication experience can be improved.

[0054] In some other embodiments, the RRC signaling is a reconfiguration signaling, which is used to reconfigure the configuration related to the SSB transmission of the secondary cell.

[0055] In this way, the SSB transmission-related configuration can be reconfigured through RRC signaling, which can improve the configuration flexibility, and by reconfiguring the secondary cell SSB transmission-related configuration, different communication scenarios can be adapted.

[0056] In some embodiments, the MAC CE is one of a SCell Activation / Deactivation MAC CE or an enhanced SCell Activation / Deactivation MAC CE.

[0057] The MAC CE is an existing MAC CE used to activate or deactivate the secondary cell. The MAC CE includes at least one of the following: a reserved bit and a first bit field.

[0058] Exemplarily, the reserved bit is used to indicate SSB transmission on the secondary cell to be activated. For example, when the bit value of the reserved bit is "1", it indicates that SSB transmission is performed on the secondary cell to be activated, otherwise SSB transmission on the secondary cell to be activated is not activated. For another example, when the bit value of the reserved bit is "1", it indicates that SSB transmission is performed on the secondary cell to be activated, and when the bit value of the reserved bit is "0", the indicated content can be determined according to actual conditions, and the present disclosure is not limited to this. For another example, when the bit value of the reserved bit is "1", it indicates that SSB is transmitted on demand on the secondary cell to be activated.

[0059] In another example, the first bit field is used to indicate SSB transmission on the secondary cell to be activated. The first bit field is a newly added bit field in the MAC CE or the first bit field is an existing bit field in the reinterpreted MAC CE. For example, the first bit field includes 1 bit, and the 1 bit is used to indicate whether the secondary cell activated by the MAC CE transmits SSB. For another example, the first bit field includes N bits, where N is a positive integer. Each of the N bits is used to indicate whether a secondary cell activated by the MAC CE transmits SSB. Each of the N bits is sorted according to the index of the activated secondary cell. For example, the index of the secondary cell activated by each bit is sorted in ascending order, with the bit with the smallest index of the activated secondary cell being arranged in the first place and the bit with the largest index of the activated secondary cell being arranged in the last place.

[0060] In another example, the reserved bit is used to indicate whether the first bit field exists. For example, a reserved bit of '1' indicates that the first bit field exists; a reserved bit of '0' indicates that the first bit field does not exist or its meaning is reserved. For another example, a reserved bit of '1' indicates that the first bit field has a reinterpreted meaning; a reserved bit of '0' indicates that the first bit field has the meaning before the reinterpretation. For example, when the reserved bit is '1', the first bit field indicates whether SSB transmission on the corresponding secondary cell is activated; when the reserved bit is '0', the first bit field indicates whether the corresponding secondary cell is activated.

[0061] In this way, the MAC CE can indicate on-demand transmission of the SSB on the secondary cell to be activated, meeting the requirements for secondary cell activation. Furthermore, the reserved bit and / or the first bit field in the MAC CE can achieve flexible control of different secondary cells, thereby achieving energy saving and improving flexibility.

[0062] In some embodiments, the MAC CE is a newly introduced MAC CE. For example, the MAC CE may be a new SCell Activation / Deactivation MAC CE. The MAC CE includes at least one of the following: a second bit field, a third bit field, a fourth bit field, a fifth bit field, a sixth bit field, and a reserved bit field.

[0063] Exemplarily, the second bit field is used to indicate the activation or deactivation status of at least one secondary cell, including an activation indication or deactivation indication of at least one secondary cell. i Used to indicate the activation or deactivation status of the secondary cell with the secondary cell index (SCell index) i. For example, C i When it is 1, it indicates that the secondary cell with secondary cell index i will be activated or is in the activated state. iis 0, indicating that the secondary cell with the secondary cell index i will be deactivated or is in a deactivated state.

[0064] Another example, the second bit field C i It is used to indicate whether there is a bit field associated with the secondary cell with the secondary cell index i, such as the third bit field and / or the fourth bit field. i When it is 1, it is used to indicate that the secondary cell with the secondary cell index i is in the state of being activated or in the activated state, and there is a bit field associated with the secondary cell with the secondary cell index i, such as the third bit field and / or the fourth bit field. i When it is 0, it is used to indicate that there is no bit field associated with the secondary cell with the secondary cell index i, such as the third bit field and / or the fourth bit field. For another example, the second bit field C i When it is 0, the terminal ignores the bit field associated with the secondary cell with the secondary cell index i, such as the third bit field and / or the fourth bit field.

[0065] In this way, the activation state of the secondary cell can be flexibly controlled through the second bit field carried by the MAC CE, and the second bit field can also indicate other bit fields associated with the secondary cell, thereby improving flexibility in the communication process.

[0066] Exemplarily, the third bit field is an activation or deactivation flag, which includes an activation indication or a deactivation indication, and the activation indication or deactivation indication is used to indicate at least one of the following: activation or deactivation of an associated secondary cell, and activation or deactivation of SSB transmission on an associated secondary cell. For example, when the third bit field is set to "1", it is used to indicate an activation operation; otherwise, it indicates a deactivation operation.

[0067] In another example, the third bit field includes 1 bit, which is used to indicate activation or deactivation of a specified secondary cell, and / or whether to activate SSB transmission on the specified secondary cell. The specified secondary cell includes any of the following: all secondary cells associated with the new SCell Activation / Deactivation MAC CE, and the secondary cell to be activated associated with the new SCell Activation / Deactivation MAC CE.

[0068] In another example, the third bit field includes multiple bits. Each bit in the multiple bits is associated with a secondary cell. For example, bit T i Used to indicate activation or deactivation of the secondary cell with the secondary cell index i, and / or indicate activation or deactivation of SSB transmission on the secondary cell with the secondary cell index i.

[0069] In this way, the third bit field carried by the MAC CE can flexibly indicate the activation or deactivation of each secondary cell and determine whether to perform SSB transmission, thereby achieving refined control of the secondary cell and improving the flexibility and efficiency of communication.

[0070] Exemplarily, the fourth bit field includes an identifier of at least one secondary cell, and may be used to indicate an identity document (ID) of a serving cell or an index of a secondary cell.

[0071] In this way, the fourth bit field carried by the MAC CE can accurately identify the designated secondary cell, thereby improving the accuracy of the MAC CE indicating activation or deactivation of the secondary cell.

[0072] Exemplarily, the fifth bit field includes an indication of the SSB pattern, which is an indication of the SSB transmission pattern. For example, the fifth bit field is used to indicate the index of the SSB pattern, and the index of the SSB pattern is associated with an SSB pattern. For another example, the fifth bit field may include M bits, where M may be 1, 2, or 3. The SSB pattern includes at least one of the following: the transmission period of the SSB, the number of transmissions of the SSB, the subcarrier spacing of the SSB, the index of the actually transmitted SSB, and the transmission power of the SSB.

[0073] In this way, the fifth bit field carried by the MAC CE can realize flexible control of the SSB pattern, and can also adjust the SSB pattern according to the transmission requirements to meet different transmission requirements and improve transmission efficiency.

[0074] Exemplarily, the sixth bit field is used to indicate whether an aperiodic positioning reference signal is to be activated on the secondary cell to be activated. The sixth bit field may occupy one or more bytes, and each of the one or more bytes occupied by the sixth bit field is used to indicate whether an aperiodic positioning reference signal is to be activated on a secondary cell to be activated. The bytes in the sixth bit field may be sorted according to the index of the indicated secondary cell, for example, in ascending order of the index of the indicated secondary cell. The aperiodic positioning reference signal may be a tracking reference signal (TRS).

[0075] It should be understood that the sixth bit field will exist in the MAC CE only when the MAC CE indicates activation of the secondary cell.

[0076] In this way, the activation / transmission of the non-periodic positioning reference signal on the secondary cell can be dynamically triggered through the sixth bit field carried by the MAC CE, which can reduce the activation delay of the secondary cell and improve network efficiency.

[0077] Exemplarily, the reserved bit field may include one or more bits.

[0078] As an implementation manner, the MAC CE may indicate that SSB transmission is to be performed on the secondary cell to be activated by carrying the second bit field, the third bit field, and the reserved bit field.

[0079] For example, as shown in FIG3 , the MAC CE includes 2 bytes. The second bit field C i Occupies some bits in the first byte, the second bit field C i It is used to indicate the activation or deactivation of the secondary cell with the secondary cell index i, and can indicate the activation or deactivation of up to 7 secondary cells. i Occupies part of the second byte, the third bit field T i Used to indicate whether to activate or deactivate the transmission of the SSB on the secondary cell with the secondary cell index i, and can indicate the transmission of the SSB on up to 7 secondary cells. The reserved bit field occupies 1 bit of the first byte and 1 bit of the second byte.

[0080] In another example, as shown in FIG4 , the MAC CE includes 8 bytes. The second bit field C i Occupies some bits in the first byte and all bits in the second, third, and fourth bytes. i It is used to indicate the activation or deactivation of the secondary cell with the secondary cell index i, and can indicate the activation or deactivation of up to 31 secondary cells. The third bit field occupies some bits in the fifth byte and all bits in the sixth, seventh and eighth bytes. The third bit field T i Used to indicate whether to activate or deactivate the transmission of SSB on the secondary cell with secondary cell index i. It can indicate the transmission of SSB on up to 31 secondary cells. The reserved bit field occupies 1 bit in the first byte and 1 bit in the fifth byte. i When it is 0, the terminal ignores the T in the third bit field. i instructions.

[0081] As an implementation manner, the MAC CE may indicate that SSB transmission is to be performed on the secondary cell to be activated by carrying the second bit field and the third bit field.

[0082] Exemplarily, as shown in FIG5 , the MAC CE includes one byte. The second bit field occupies multiple bits in one byte, and each of the multiple bits indicates the activation or deactivation of a secondary cell.

The third bit field occupies 1 bit and is used to indicate the transmission of SSBs on all secondary cells associated with the MAC CE or secondary cells to be activated.

[0083] As an implementation manner, the MAC CE may indicate that SSB transmission is to be performed on the secondary cell to be activated by carrying the third bit field, the fourth bit field, and the reserved bit field.

The fourth bit field includes the serving cell ID of the secondary cell to be activated. i The third bit field T occupies one bit in the first byte and is used to indicate whether to activate or deactivate the secondary cell indicated by the fourth bit field in the same byte, and / or to activate or deactivate SSB transmission on the secondary cell indicated by the fourth bit field in the same byte. The reserved bit field occupies two bits in the first byte and three bits in each of the other bytes.

[0087] As an implementation manner, the MAC CE may indicate that SSB transmission is to be performed on the secondary cell to be activated by carrying the third bit field, the fourth bit field, and the fifth bit field.

[0094] S102: Based on the first signaling, detect an SSB on at least one secondary cell.

[0095] In some embodiments, in response to receiving the first signaling, the terminal detects an SSB on at least one secondary cell.

[0096] As an implementation method, the SSB on at least one secondary cell is transmitted based on the first SSB configuration information.

[0097] The first SSB configuration information includes at least one of the following: SSB transmission period, SSB transmission times, SSB subcarrier spacing, SSB index, SSB transmission power, and SSB time domain offset.

[0098] Exemplarily, the time domain offset of the SSB is the interval between the time slot where the first signaling is located and the time slot of the SSB transmission.

[0099] In some embodiments, the first SSB configuration information is configured via RRC signaling; or, the first SSB configuration information is configured via a system information block (SIB); or, the first SSB configuration information is predefined. The SIB may be SIB1 or other system information (OSI) other than SIB1.

[0100] As another implementation, the SSB on at least one secondary cell is transmitted based on the first SSB configuration information within a first time period.

[0101] In some embodiments, the starting point of the first time period is determined according to at least one of the following: a transmission time of the first signaling, and a first time offset.

[0102] For example, the starting point of the first time period may be determined solely based on the transmission time of the first signaling. For example, the starting point of the first time period may be the time when the first signaling is received. For another example, the starting point of the first time period may be the time when the first signaling is completely received.

[0103] In another example, the starting point of the first time period may be determined solely based on the first time offset. For example, the starting point of the first time period may be the time corresponding to the first time offset after the start of SSB transmission. For example, if the time when SSB transmission starts is T and the first time offset is P, the starting point of the first time period is T+P.

[0104] In another example, the starting point of the first time period may be determined based on the transmission time of the first signaling and the first time offset. For example, the starting point of the first time period may be the time corresponding to the first time offset after the first signaling is received. For another example, the starting point of the first time period may be the time corresponding to the first time offset after the first signaling is received.

[0105] As an implementation manner, the first time offset is determined according to at least one of the following: a predefined time period, RRC signaling, SIB1, and a master information block (MIB).

[0106] Exemplarily, the first time offset may be a predefined time period, or the first time offset may be configured by RRC signaling, or the first time offset may be configured by SIB1, or the first time offset may be configured by MIB.

[0107] In some embodiments, the end point of the first time period is the moment corresponding to the completion of activation of at least one secondary cell; or, the end point of the first time period is the moment corresponding to the successful reporting of channel state information CSI by at least one secondary cell; or, the end point of the first time period is determined according to a preset time period.

[0108] For example, the end point of the first time period may be a time corresponding to the scheduled time period after the start point of the first time period. For example, if the start point of the first time period is T and the scheduled time period is P, the end point of the first time period is T+P.

[0109] It should be understood that when the end point of the first time period is the moment corresponding to the completion of activation of at least one secondary cell, the first SSB configuration information is valid at the moment corresponding to the completion of activation of at least one secondary cell. When the end point of the first time period is the moment corresponding to the successful reporting of channel state information CSI by at least one secondary cell, the first SSB configuration information is valid at the moment corresponding to the successful reporting of channel state information CSI by at least one secondary cell.

[0110] It should be noted that the first SSB configuration information is always valid after triggering the transmission of the SSB on at least one secondary cell, or is valid only during a first time period. The first time period is within the time period corresponding to the activation process of at least one secondary cell; alternatively, the first time period may also be a predefined time period.

[0111] In some embodiments, after the first SSB configuration information becomes invalid, the second SSB configuration information is switched to transmit SSB.

[0112] Exemplarily, before at least one secondary cell is activated or before at least one secondary cell successfully reports channel state information CSI, the first SSB configuration information is used to transmit the SSB. After at least one secondary cell is activated or after at least one secondary cell successfully reports channel state information CSI, the second SSB configuration information is used to transmit the SSB.

[0113] The transmission period of the SSB in the first SSB configuration information is different from the transmission period of the SSB in the second SSB configuration information. For example, the transmission period of the SSB in the first SSB configuration information is 5 ms, and the transmission period of the SSB in the second SSB configuration information is 160 ms.

[0114] Exemplarily, when the terminal receives the first signaling, activates at least one secondary cell, and triggers the transmission of the SSB on at least one secondary cell, the SSB is transmitted according to the SSB transmission period of 5ms in the first SSB configuration information. After the activation of at least one secondary cell is completed or at least one secondary cell successfully reports the channel state information CSI, the SSB transmission period in the second SSB configuration information is 160ms, and the SSB is transmitted.

[0115] It should be noted that after the first SSB configuration information becomes invalid, there may be no SSB that needs to be transmitted unless the SSB transmission is triggered again; or, the first SSB configuration information remains valid until new SSB configuration information is received.

[0116] In this way, one type of configuration information is used to transmit the SSB before the secondary cell is activated, and another type of configuration information is used to transmit the SSB after the activation, thereby realizing on-demand transmission of the SSB and reducing transmission energy consumption.

[0117] As an implementation method, the terminal detects the SSB on at least one secondary cell within the first time period.

[0118] As another implementation manner, after receiving the first signaling, the terminal immediately detects the SSB on at least one secondary cell.

[0119] In this way, through the first signaling, SSB can be transmitted on demand instead of periodically. On the basis of ensuring the transmission needs of the terminal, the energy consumption of the base station can be reduced, thereby reducing the cost of the operator. Moreover, on-demand transmission of SSB can improve the flexibility of SSB transmission, thereby improving the utilization rate of network resources.

[0120] FIG14 shows a flow chart of a signaling sending method provided by the present disclosure. As shown in FIG14 , the signaling receiving method is applied to the base station 20 in FIG1 , and includes the following steps:

[0121] S201: Send a first signaling.

[0122] The first signaling is used to trigger the transmission of at least one synchronization signal / physical broadcast channel block SSB on at least one secondary cell. The first signaling includes at least one of the following: radio resource control RRC signaling, media access control element MAC CE, and downlink control information.

[0123] In some embodiments, the MAC CE is an existing MAC CE used to activate or deactivate a secondary cell.

[0124] The reserved bit in the MAC CE is used to indicate that SSB transmission is performed on the secondary cell to be activated. The first bit field in the MAC CE is used to indicate that SSB transmission is performed on the secondary cell to be activated.

[0125] In some embodiments, the MAC CE includes at least one of the following: a second bit field, a third bit field, a fourth bit field, a fifth bit field, a sixth bit field, and a reserved bit field; the second bit field includes an activation indication or a deactivation indication of at least one secondary cell; the third bit field includes an activation indication or a deactivation indication; the fourth bit field includes an identifier of the secondary cell; the fifth bit field includes an indication of an SSB pattern; the sixth bit field is used to indicate whether a non-periodic positioning reference signal will be activated on the secondary cell to be activated.

[0126] The third bit field is used to indicate at least one of the following: activation or deactivation of an associated secondary cell, or activation or deactivation of SSB transmission on an associated secondary cell. The SSB pattern includes at least one of the following: SSB transmission period, SSB transmission count, SSB subcarrier spacing, index of the actually transmitted SSB, and SSB transmission power.

[0127] In some embodiments, the SSB on at least one secondary cell is transmitted based on the first SSB configuration information.

[0128] The first SSB configuration information includes at least one of the following: SSB transmission period, SSB transmission times, SSB subcarrier spacing, SSB index, SSB transmission power, and SSB time domain offset.

[0129] In some embodiments, the first SSB configuration information is configured through RRC signaling; or, the first SSB configuration information is configured through a system information block; or, the first SSB configuration information is predefined.

[0130] In some embodiments, at least one secondary cell transmits based on the first SSB configuration information within a first time period.

[0131] In some embodiments, the starting point of the first time period is determined based on at least one of: the transmission time of the first signaling, the first time offset; the first time offset is configured through RRC signaling; or, the first time offset is configured through SIB1; or, the first time offset is configured through MIB; or, the first time offset is predefined.

[0132] In some embodiments, the end point of the first time period is the moment corresponding to the completion of activation of at least one secondary cell; or, the end point of the first time period is the moment corresponding to the successful reporting of channel state information CSI by at least one secondary cell; or, the end point of the first time period is determined according to a preset time period.

[0133] In this way, the first signaling enables on-demand transmission of SSBs, rather than periodic transmission. This reduces base station energy consumption while ensuring the transmission needs of the terminal, thereby reducing operator costs. Furthermore, on-demand transmission of SSBs can increase the flexibility of SSB transmission, thereby improving network resource utilization.
