Description

Method and apparatus for transmitting synchronization signal configuration information

[0001] This disclosure claims priority to Chinese Patent Application No. 202510122871.9, filed with the Chinese Patent Office on January 26, 2025, entitled “Method and Apparatus for Transmitting Synchronization Signal Configuration Information”, the entire contents of which are incorporated herein by reference. Technical Field

[0002] This disclosure relates to the field of communication technology, and in particular to a method and apparatus for transmitting synchronization signal configuration information. Background Technology

[0003] In related technologies, the synchronization signal is a Synchronization Signal / PBCH Block (SSB), which is transmitted through SSB burst sets. SSBs within a burst set are transmitted using the same period. When multiple Transmission / Reception Points (TRPs) exist in a cell, the SSBs in this burst set will be transmitted on different TRPs, but all will use the same transmission period. When the traffic volume of some TRPs in a cell decreases, those TRPs may not need to transmit data, but the period of the synchronization signal on those TRPs needs to be consistent with the period of the synchronization signals on other TRPs in the cell. They still need to send synchronization signals as if data transmission is in progress, resulting in higher energy consumption for both the network and the terminal. Summary of the Invention

[0042] The technical solutions of the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this disclosure. Based on the embodiments of this disclosure, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this disclosure.

[0043] The terms “first,” “second,” etc., used in this disclosure and in the claims are used to distinguish similar objects and are not necessarily used to describe a particular order or sequence. It should be understood that such use of data can be interchanged where appropriate so that embodiments of this disclosure described herein may be implemented, for example, in sequences other than those illustrated or described herein. Furthermore, the terms “comprising” and “having,” and any variations thereof, are intended to cover a non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.

[0044] In this disclosure, the term "and / or" describes the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, or B existing alone. The character " / " generally indicates that the preceding and following related objects have an "or" relationship. In this disclosure, the term "multiple" refers to two or more objects, and other quantifiers are similar.

[0045] In this disclosure, the terms "exemplary" or "for example" are used to indicate that something is an example, illustration, or description. Any embodiment or design described as "exemplary" or "for example" in this disclosure should not be construed as being more preferred or advantageous than other embodiments or designs. Specifically, the use of terms such as "exemplary" or "for example" is intended to present the relevant concepts in a specific manner.

[0046] To enable those skilled in the art to better understand the embodiments of this disclosure, the following description will be provided first.

[0047] In relevant communication systems (such as 5G New Radio (NR) systems or 6G systems), synchronization signals are called synchronization blocks, which are transmitted through SSB burst sets. Specifically, the SSB positions in the burst indicate the actual number and location of transmitted SSBs. Typically, each SSB corresponds to a beam direction. SSBs within a burst set are transmitted using the same period. When a Transmission Point Retention Platform (TRP) exists in the cell, the SSBs in this burst set will be transmitted on different TRPs, but all will use the same transmission period. Simultaneously, each TRP can send a Tracking Reference Signal (TRS) for the terminal to synchronize with that TRP in time and frequency. Each TRP also sends a Channel State Information Reference Signal (CSI-RS), and after measurement, the terminal reports the CSI information of the corresponding TRP.

[0048] The solutions disclosed in this embodiment can be applied to 5G and 6G systems.

[0049] The method for transmitting synchronization signal configuration information provided in this disclosure will be described in detail below with reference to the accompanying drawings and through some embodiments and application scenarios.

[0050] As shown in Figure 1, this embodiment of the present disclosure provides a method for transmitting synchronization signal configuration information, including:

[0051] Step 101: The terminal receives first information, which includes at least one of the following:

[0052] A1: System message, which includes configuration information for at least two synchronization signal groups of a synchronization signal set.

[0053] A2: First signaling, the first signaling is used to instruct the terminal to select a first parameter value from multiple parameter values ​​of the first configuration parameter, the first configuration parameter being the configuration parameter in the configuration information of the synchronization signal group.

[0054] A3: Second signaling, the second signaling is used to indicate the activation of at least one of the transmission of measurement reporting and reference signals corresponding to the first synchronization signal group; or, the second signaling is used to indicate the deactivation of at least one of the transmission of measurement reporting and reference signals corresponding to the second synchronization signal group; wherein, the first synchronization signal group and the second synchronization signal group are synchronization signal groups in the synchronization signal set, and the measurement reporting includes measurement reporting of channel state information.

[0055] In the above-described scheme of this disclosure embodiment, a set of synchronization signals is divided into multiple synchronization signal groups. Different synchronization signal groups correspond to different configuration information, and different synchronization signal groups can correspond to different TRPs in the same cell. Thus, the aforementioned first information enables the terminal to transmit synchronization signals on different TRPs according to different configuration information, and / or enables the terminal to realize measurement reporting and / or reference signal transmission on some TRPs. This allows the terminal to enable or disable some TRPs in the same cell based on the traffic volume on the TRP, thereby helping to reduce the energy consumption of the network and the terminal.

[0056] In some implementations of this disclosure, for item A1 above: each of the above synchronization signal groups corresponds to a set of synchronization signals, and each set of synchronization signals includes at least one synchronization signal from the set of synchronization signals.

[0057] For example, a set of synchronization signals may be divided into two synchronization signal groups, such as synchronization signal group 1 and synchronization signal group 2. The aforementioned system message includes configuration information for synchronization signal group 1 and configuration information for synchronization signal group 2.

[0058] In some implementations of this disclosure, for item A2 above: the first signaling can be downlink control information (DCI). This first signaling can be scrambled using a System Information Radio Network Temporary Identifier (SI-RNTI) or a Paging Radio Network Temporary Identifier (P-RNTI).

[0059] The configuration information of the aforementioned synchronization signal group includes multiple configuration parameters. The first configuration parameter can include multiple parameter values, and the first signaling is used to instruct the terminal to select one parameter value from the multiple parameter values. For example, the first configuration parameter is the period of the synchronization signal of group 1, and the parameter values ​​of this period include 20 milliseconds (ms), 80 ms, and 160 ms. The first signaling is used to indicate that the period of the synchronization signal of group 1 is 20 ms.

[0060] In some embodiments of this disclosure, each synchronization signal packet corresponds to a Transmission / Reception Point (TRP). Based on system messages and first signaling, the terminal can determine the configuration information of the corresponding synchronization signal packet, and then determine the configuration information of the synchronization signal packet corresponding to the corresponding TRP. This achieves the purpose of configuring different synchronization signal parameters for different TRPs corresponding to the same synchronization signal set. For example, different TRPs correspond to different synchronization signal periods, with TRPs with lower traffic volume corresponding to larger synchronization signal periods and TRPs with higher traffic volume corresponding to smaller synchronization signal periods, instead of multiple TRPs in a cell corresponding to the same synchronization signal period, which is beneficial for network energy saving.

[0061] In some embodiments of this disclosure, regarding item A3 above: the aforementioned measurement reporting may be Channel State Information (CSI) reporting. The aforementioned transmission of the reference signal may be the transmission of a Tracking Reference Signal (TRS).

[0062] The second signaling mentioned above can activate or deactivate the transmission of measurement reporting and / or reference signals corresponding to the corresponding synchronization signal group. This allows for the activation or deactivation of some TRPs based on their traffic volume, thereby improving network energy efficiency.

[0063] In some embodiments of this disclosure, when the terminal is in a disconnected state, the first message may include a system message and a first signaling, or may include a system message.

[0064] Alternatively, if the terminal is in a connected state, the first message may include the second signaling, or it may include the second signaling and a system message.

[0065] The first piece of information mentioned above is sent from the network device to the terminal, and the network device may specifically be a base station.

[0066] The set of synchronization signals in this embodiment of the disclosure may be an SSB burst set.

[0067] In some implementations of this disclosure, the configuration information of the synchronization signal group includes at least one of the following configuration parameters: the index of the synchronization signal; the position of the synchronization signal in the synchronization signal set; the period of the synchronization signal; and the transmission power of the synchronization signal.

[0068] In some implementations of this disclosure, the configuration parameters within each synchronization signal group include at least one of the following: the index of the synchronization signal; the position of the synchronization signal in the synchronization signal set; the period of the synchronization signal; and the transmission power of the synchronization signal.

[0069] The period of the aforementioned synchronization signal is used to indicate the period of the synchronization signal in the corresponding synchronization signal group, and the transmission power of the aforementioned synchronization signal is used to indicate the transmission power of the synchronization signal in the corresponding synchronization signal group.

[0070] In this embodiment of the disclosure, the position of the synchronization signal within the synchronization signal set can be indicated by SSB_PositioninBurst. For example, the aforementioned synchronization signal set includes synchronization signal group 1 and synchronization signal group 2. This synchronization signal set includes 8 synchronization signals. SSB_PositioninBurst in synchronization signal group 1 is represented by SSB_PositioninBurst1, and SSB_PositioninBurst in synchronization signal group 2 is represented by SSB_PositioninBurst2. Then:

[0071] SSB_PositioninBurst1=11110000;

[0072] SSB_PositioninBurst2=11110000.

[0073] Since this set of synchronization signals contains a maximum of 8 synchronization signals, an 8-bit bitmap is used to indicate the position of each synchronization signal within the set. A 1 in the corresponding bit indicates that the synchronization signal at that position belongs to the corresponding group. For example, in the above indication, it means that the first 4 synchronization signals belong to synchronization signal group 1, and the last 4 belong to synchronization signal group 2.

[0074] In some implementations of this disclosure, the periods of the synchronization signals in different synchronization signal groups can be the same or different. For example, the period of the synchronization signal in synchronization signal group 1 is 20ms, and the period of the synchronization signal in synchronization signal group 2 is 160ms; or, the periods of the synchronization signals in synchronization signal group 1 include 20ms and 160ms, and the periods of the synchronization signals in synchronization signal group 2 include 20ms and 160ms.

[0075] As a first implementation in some embodiments, the configuration information of the synchronization signal group includes a configuration parameter group, which includes at least two configuration parameters, and each configuration parameter includes one or more parameter values.

[0076] Alternatively, as a second implementation in some embodiments, the configuration information of the synchronization signal group includes at least two configuration parameter groups, and the configuration parameter in each configuration parameter group includes a parameter value.

[0077] In this embodiment of the disclosure, the configuration parameters in the configuration parameter group include at least one of the following: the index of the synchronization signal; the position of the synchronization signal in the synchronization signal set; the period of the synchronization signal; and the transmission power of the synchronization signal.

[0078] For example, in some implementations of the first method described above, the configuration information of synchronization signal group 1 includes:

[0079] The position of the synchronization signal in the synchronization signal set of Group 1: SSB_PositioninBurst1 = '11110000';

[0080] The period of the synchronization signal for Group 1 is 20ms, 80ms, and 160ms.

[0081] The transmission power of the synchronization signal in Group 1 is 40dBm.

[0082] In some implementations of the second method described above, for example, the configuration information of synchronization signal group 1 includes three configuration parameter groups:

[0083] Configuration parameter group 1 for synchronization signal group 1:

[0084] The position of the synchronization signal in the synchronization signal set of Group 1: SSB_PositioninBurst1 = '11110000';

[0085] The period of the synchronization signal for group 1 is 20ms;

[0086] The transmission power of the synchronization signal in Group 1 is 40dBm.

[0087] Configuration parameter group 2 for synchronization signal group 1:

[0088] The position of the synchronization signal in the synchronization signal set of Group 1: SSB_PositioninBurst1 = '11110000';

[0089] The period of the synchronization signal for Group 1 is 80ms;

[0090] The transmission power of the synchronization signal in Group 1 is 40dBm.

[0091] Configuration parameter group 3 for synchronization signal group 1:

[0092] The position of the synchronization signal in the synchronization signal set of Group 1: SSB_PositioninBurst1 = '11110000';

[0093] The period of the synchronization signal for group 1 is 160ms;

[0094] The transmission power of the synchronization signal in Group 1 is 20dBm.

[0095] In some implementations of this disclosure, when the configuration information of the synchronization signal group includes a configuration parameter group, the first signaling is used to indicate that the parameter value of the first configuration parameter is the first parameter value;

[0096] Alternatively, if the configuration information of the synchronization signal group includes at least two configuration parameter groups, the first signaling is used to indicate the index of the configuration parameter group corresponding to the first parameter value.

[0097] In some implementations of this disclosure, the first configuration parameter includes at least one of the period of the synchronization signal and the transmission power of the synchronization signal.

[0098] For example, in some embodiments of the first implementation described above, the first signaling indicates that the period of the synchronization signal of synchronization signal group 1 is 20ms. In some embodiments of the second implementation described above, the first signaling indicates that the period of the synchronization signal of synchronization signal group 1 is the period in configuration parameter group 2.

[0099] In some implementations of this disclosure, the second signaling includes:

[0100] Activation or deactivation instruction;

[0101] A synchronization signal packet indicator, wherein the synchronization signal packet indicator is used to indicate the first synchronization signal packet or the second synchronization signal packet;

[0102] An identification indicator is used to indicate at least one of the identification of a reference signal and the identification of a measurement report.

[0103] When the second signaling includes an activation indication, the second signaling is used to indicate the transmission of the reference signal corresponding to the identifier of the reference signal to be activated, and / or to indicate the measurement reporting corresponding to the identifier of the measurement reporting to be activated.

[0104] When the second signaling includes a deactivation indication, the second signaling is used to indicate the deactivation of the transmission of the reference signal corresponding to the synchronization signal group indicated by the synchronization signal group and / or the associated measurement reporting. For example, the second signaling is used to indicate the deactivation of the transmission of the reference signal corresponding to the second synchronization signal group and / or the corresponding measurement reporting.

[0105] The second signaling mentioned above can activate or deactivate the transmission of measurement reporting and / or reference signals corresponding to the corresponding synchronization signal group. This allows for the activation or deactivation of some TRPs based on their traffic volume, thereby improving network energy efficiency.

[0106] In some implementations of this disclosure, the second signaling further includes at least one of the following:

[0107] A period indicator for a synchronization signal, the period indicator being used to indicate the period of the synchronization signal in the first synchronization signal group or the second synchronization signal group;

[0108] Periodic indication of measurement reporting.

[0109] In some implementations of this disclosure, when the second signaling includes a deactivation indication, the reference signal corresponding to the second synchronization signal packet and the synchronization signal in the second synchronization signal packet have a quasi-co-location (QCL) relationship.

[0110] The reference signal corresponding to the second synchronization signal group has a direct or indirect QCL relationship with the synchronization signal in the second synchronization signal group.

[0111] In some implementations of this disclosure, when the second signaling includes a deactivation indication, the measurement report corresponding to the second synchronization signal group includes a measurement report of first channel state information, wherein the reference signal associated with the first channel state information is the synchronization signal in the second synchronization signal group, or the reference signal associated with the first channel state information has a QCL relationship with the synchronization signal in the second synchronization signal group.

[0112] The reference signal associated with the first channel state information mentioned above refers to the reference signal that needs to be measured to obtain the first channel state information.

[0113] Here, the reference signal associated with the first channel state information has a direct or indirect QCL relationship with the synchronization signal in the second synchronization signal group.

[0114] In some implementations of this disclosure, the activation indication corresponds to different Radio Network Temporary Identifier (RNTI) scrambling information. Thus, activation and deactivation indications can be distinguished using different RNTIs.

[0115] In some embodiments, the method of this disclosure further includes:

[0116] When the second signaling includes a periodic indication for the measurement reporting, the measurement resource for the measurement reporting is determined based on the synchronization signal in the first synchronization signal group or the second synchronization signal group.

[0117] When the second signaling includes the measurement reporting period indication, the synchronization signal in the first synchronization signal group or the second synchronization signal group is used as the measurement resource for measurement reporting, such as the synchronization signal in the first synchronization signal group or the second synchronization signal group is used as the configuration for all CSI reporting, and the period of CSI measurement reporting corresponding to the synchronization signal group is updated through the above measurement reporting period indication.

[0118] In some implementations of this disclosure, the synchronization signal includes a primary synchronization signal and a secondary synchronization signal;

[0119] Alternatively, the synchronization signal may include a primary synchronization signal, a secondary synchronization signal, and a broadcast channel.

[0120] In some implementations of this disclosure, the first signaling is used to schedule the resources of the system message, or the first signaling is a paging indication, or the first signaling is a higher-level signaling.

[0121] In the above-described scheme of this disclosure embodiment, a set of synchronization signals is divided into multiple synchronization signal groups. Different synchronization signal groups correspond to different configuration information, and different synchronization signal groups can correspond to different TRPs in the same cell. Thus, the aforementioned first information enables the terminal to transmit synchronization signals on different TRPs according to different configuration information, and / or enables the terminal to realize measurement reporting and / or reference signal transmission on some TRPs. This allows the terminal to enable or disable some TRPs in the same cell based on the traffic volume on the TRP, thereby helping to reduce the energy consumption of the network and the terminal.

[0122] As shown in Figure 2, this embodiment of the present disclosure also provides a method for transmitting synchronization signal configuration information, including:

[0123] Step 201: The network device sends first information, the first information including at least one of the following:

[0124] A1: System message, which includes configuration information for at least two synchronization signal groups of a synchronization signal set.

[0125] A2: First signaling, the first signaling is used to instruct the terminal to select a first parameter value from multiple parameter values ​​of the first configuration parameter, the first configuration parameter being the configuration parameter in the configuration information of the synchronization signal group.

[0126] A3: Second signaling, the second signaling is used to indicate the activation of at least one of the transmission of measurement reporting and reference signals corresponding to the first synchronization signal group; or, the second signaling is used to indicate the deactivation of at least one of the transmission of measurement reporting and reference signals corresponding to the second synchronization signal group; wherein, the first synchronization signal group and the second synchronization signal group are synchronization signal groups in the synchronization signal set, and the measurement reporting includes measurement reporting of channel state information.

[0127] In the above-described scheme of this disclosure embodiment, a set of synchronization signals is divided into multiple synchronization signal groups. Different synchronization signal groups correspond to different configuration information, and different synchronization signal groups can correspond to different TRPs in the same cell. Thus, the aforementioned first information enables the terminal to transmit synchronization signals on different TRPs according to different configuration information, and / or enables the terminal to realize measurement reporting and / or reference signal transmission on some TRPs. This allows the terminal to enable or disable some TRPs in the same cell based on the traffic volume on the TRP, thereby helping to reduce the energy consumption of the network and the terminal.

[0128] In some implementations of this disclosure, for item A1 above: each of the above synchronization signal groups corresponds to a set of synchronization signals, and each set of synchronization signals includes at least one synchronization signal from the set of synchronization signals.

[0129] For example, a set of synchronization signals may be divided into two synchronization signal groups, such as synchronization signal group 1 and synchronization signal group 2. The aforementioned system message includes configuration information for synchronization signal group 1 and configuration information for synchronization signal group 2.

[0130] In some implementations of this disclosure, for item A2 above: the first signaling can be downlink control information (DCI). This first signaling can be scrambled using a System Information Radio Network Temporary Identifier (SI-RNTI) or a Paging Radio Network Temporary Identifier (P-RNTI).

[0131] The configuration information of the aforementioned synchronization signal group includes multiple configuration parameters. The first configuration parameter can include multiple parameter values, and the first signaling is used to instruct the terminal to select one parameter value from the multiple parameter values. For example, the first configuration parameter is the period of the synchronization signal of group 1, and the parameter values ​​of this period include 20ms, 80ms, and 160ms. The first signaling is used to indicate that the period of the synchronization signal of group 1 is 20ms.

[0132] In some embodiments of this disclosure, each synchronization signal packet corresponds to a Transmission / Reception Point (TRP). Based on system messages and first signaling, the terminal can determine the configuration information of the corresponding synchronization signal packet, and then determine the configuration information of the synchronization signal packet corresponding to the corresponding TRP. This achieves the purpose of configuring different synchronization signal parameters for different TRPs corresponding to the same synchronization signal set. For example, different TRPs correspond to different synchronization signal periods, with TRPs with lower traffic volume corresponding to larger synchronization signal periods and TRPs with higher traffic volume corresponding to smaller synchronization signal periods, instead of multiple TRPs in a cell corresponding to the same synchronization signal period, which is beneficial for network energy saving.

[0133] In some embodiments of this disclosure, regarding item A3 above: the aforementioned measurement reporting may be Channel State Information (CSI) reporting. The aforementioned transmission of the reference signal may be the transmission of a Tracking Reference Signal (TRS).

[0134] The second signaling mentioned above can activate or deactivate the transmission of measurement reporting and / or reference signals corresponding to the corresponding synchronization signal group. This allows for the activation or deactivation of some TRPs based on their traffic volume, thereby improving network energy efficiency.

[0135] In some embodiments of this disclosure, when the terminal is in a disconnected state, the first message may include a system message and a first signaling, or may include a system message.

[0136] Alternatively, if the terminal is in a connected state, the first message may include the second signaling, or it may include the second signaling and a system message.

[0137] The first piece of information mentioned above is sent from the network device to the terminal, and the network device may specifically be a base station.

[0138] The set of synchronization signals in this embodiment of the disclosure may be an SSB burst set.

[0139] In some implementations of this disclosure, the configuration information of the synchronization signal group includes at least one of the following configuration parameters: the index of the synchronization signal; the position of the synchronization signal in the synchronization signal set; the period of the synchronization signal; and the transmission power of the synchronization signal.

[0140] The period of the aforementioned synchronization signal is used to indicate the period of the synchronization signal in the corresponding synchronization signal group, and the transmission power of the aforementioned synchronization signal is used to indicate the transmission power of the synchronization signal in the corresponding synchronization signal group.

[0141] The configuration information for the synchronization signal group has been described in detail in the method embodiment on the terminal side, and will not be repeated here.

[0142] In some implementations of this disclosure, the configuration information of the synchronization signal group includes a configuration parameter group, and the configuration parameter group includes at least two configuration parameters, and each configuration parameter includes one or more parameter values;

[0143] Alternatively, the configuration information of the synchronization signal group may include at least two configuration parameter groups, and each configuration parameter group may include a parameter value.

[0144] In some implementations of this disclosure, when the configuration information of the synchronization signal group includes a configuration parameter group, the first signaling is used to indicate that the parameter value of the first configuration parameter is the first parameter value;

[0145] Alternatively, if the configuration information of the synchronization signal group includes at least two configuration parameter groups, the first signaling is used to indicate the index of the configuration parameter group corresponding to the first parameter value.

[0146] In some implementations of this disclosure, the first configuration parameter includes at least one of the period of the synchronization signal and the transmission power of the synchronization signal.

[0147] In some implementations of this disclosure, the second signaling includes:

[0148] Activation or deactivation instruction;

[0149] A synchronization signal packet indicator, wherein the synchronization signal packet indicator is used to indicate the first synchronization signal packet or the second synchronization signal packet;

[0150] An identification indicator is used to indicate at least one of the identification of a reference signal and the identification of a measurement report.

[0151] When the second signaling includes an activation indication, the second signaling is used to indicate the transmission of the reference signal corresponding to the identifier of the reference signal to be activated, and / or to indicate the measurement reporting corresponding to the identifier of the measurement reporting to be activated.

[0152] When the second signaling includes a deactivation indication, the second signaling is used to indicate the deactivation of the transmission of the reference signal corresponding to the synchronization signal group indicated by the synchronization signal group and / or the associated measurement reporting. For example, the second signaling is used to indicate the deactivation of the transmission of the reference signal corresponding to the second synchronization signal group and / or the corresponding measurement reporting.

[0153] The second signaling mentioned above can activate or deactivate the transmission of measurement reporting and / or reference signals corresponding to the corresponding synchronization signal group. This allows for the activation or deactivation of some TRPs based on their traffic volume, thereby improving network energy efficiency.

[0154] In some implementations of this disclosure, the second signaling further includes at least one of the following:

[0155] A period indicator for a synchronization signal, the period indicator being used to indicate the period of the synchronization signal in the first synchronization signal group or the second synchronization signal group;

[0156] Periodic indication of measurement reporting.

[0157] In some implementations of this disclosure, when the second signaling includes a deactivation indication, the reference signal corresponding to the second synchronization signal group and the synchronization signal in the second synchronization signal group have a quasi-co-location (QCL) relationship.

[0158] The reference signal corresponding to the second synchronization signal group has a direct or indirect QCL relationship with the synchronization signal in the second synchronization signal group.

[0159] In some implementations of this disclosure, when the second signaling includes a deactivation indication, the measurement report corresponding to the second synchronization signal group includes a measurement report of first channel state information, wherein the reference signal associated with the first channel state information is the synchronization signal in the second synchronization signal group, or the reference signal associated with the first channel state information has a QCL relationship with the synchronization signal in the second synchronization signal group.

[0160] The reference signal associated with the first channel state information mentioned above refers to the reference signal that needs to be measured to obtain the first channel state information.

[0161] Here, the reference signal associated with the first channel state information has a direct or indirect QCL relationship with the synchronization signal in the second synchronization signal group.

[0162] In some implementations of this disclosure, the activation indication corresponds to different Radio Network Temporary Identifier (RNTI) scrambling information. Thus, activation and deactivation indications can be distinguished using different RNTIs.

[0163] In some embodiments, the method of this disclosure further includes:

[0164] When the second signaling includes a periodic indication for the measurement reporting, the measurement resource for the measurement reporting is determined based on the synchronization signal in the first synchronization signal group or the second synchronization signal group.

[0165] When the second signaling includes the measurement reporting period indication, the synchronization signal in the first synchronization signal group or the second synchronization signal group is used as the measurement resource for measurement reporting, such as the synchronization signal in the first synchronization signal group or the second synchronization signal group is used as the configuration for all CSI reporting, and the period of CSI measurement reporting corresponding to the synchronization signal group is updated through the above measurement reporting period indication.

[0166] In some implementations of this disclosure, the synchronization signal includes a primary synchronization signal and a secondary synchronization signal;

[0167] Alternatively, the synchronization signal may include a primary synchronization signal, a secondary synchronization signal, and a broadcast channel.

[0168] In some implementations of this disclosure, the first signaling is used to schedule the resources of the system message, or is a paging indication, or is a higher-level signaling.

[0169] In the above-described scheme of this disclosure embodiment, a set of synchronization signals is divided into multiple synchronization signal groups. Different synchronization signal groups correspond to different configuration information, and different synchronization signal groups can correspond to different TRPs in the same cell. Thus, the aforementioned first information enables the terminal to transmit synchronization signals on different TRPs according to different configuration information, and / or enables the terminal to realize measurement reporting and / or reference signal transmission on some TRPs. This allows the terminal to enable or disable some TRPs in the same cell based on the traffic volume on the TRP, thereby helping to reduce the energy consumption of the network and the terminal.

[0170] The method for transmitting synchronization signal configuration information disclosed herein will be described in detail below with reference to embodiments.

[0171] Example 1:

[0172] The terminal receives a synchronization signal sent by the base station. After completing synchronization based on the received synchronization signal, the terminal obtains the physical broadcast channel corresponding to this synchronization signal and determines the synchronization signal index (represented as SSB_index) to be 2. According to the indication of the physical broadcast channel, the terminal receives a first signaling, which is used to schedule system messages. This first signaling includes a synchronization signal group parameter indication field, used to indicate the synchronization signal period and / or power value of each group. For example, the system predefines a maximum of two synchronization signal groups, as shown in Table 1. The synchronization signal group parameter indication field in the first signaling includes the following two information fields, each using 2 bits, which correspond to one of four candidate values:

[0173] Table 1

[0174] Where 00 represents the first value among the maximum four candidate period values, and 10 represents the third value among the four candidate period values.

[0175] Further, the terminal receives the system message from the first signaling scheduling. The system message indicates a set of synchronization signals containing up to eight synchronization signals, which includes two synchronization signal groups. In one implementation, the specific configuration is as follows:

[0176] Synchronization signal group 1 configuration:

[0177] The position of the synchronization signal in the synchronization signal set of Group 1: SSB_PositioninBurst1 = '11110000';

[0178] The period of the synchronization signal for Group 1 is 20ms, 80ms, and 160ms.

[0179] The transmission power of the synchronization signal in Group 1 is 40dBm.

[0180] Synchronization signal group 2 configuration:

[0181] The position of the synchronization signal in the synchronization signal set of Group 2: SSB_PositioninBurst2 = '00001111';

[0182] The period of the synchronization signal for group 2 is 20ms, 80ms, and 160ms.

[0183] The transmission power of the synchronization signal in group 2 is 40dBm.

[0184] Since this synchronization signal set contains a maximum of 8 synchronization signals, the above signaling uses an 8-bit bitmap to indicate the position of the synchronization signals within the set. A corresponding bit set to 1 indicates that the synchronization signal at that position is transmitted in the corresponding group. For example, in the above indication, it is stated that the first 4 synchronization signals are in synchronization signal group 1, and the last 4 synchronization signals are in synchronization signal group 2.

[0185] Based on the instructions in the first signaling, the terminal determines that the synchronization signal for packet 1 will be transmitted with a period of 20ms, and the synchronization signal for packet 2 will be transmitted with a period of 160ms. The terminal accesses the cell based on the synchronization signal with index 2 transmitted within 20ms.

[0186] From the network side's perspective, each synchronization signal packet corresponds to a network transceiver node. Transceiver nodes that transmit synchronization signals using 20ms are in normal operating mode, while those that transmit synchronization signals using 160ms are in energy-saving operating mode.

[0187] In another implementation, the system message configures multiple sets of configurations for each synchronization signal group, as follows:

[0188] Configuration parameter group 1 for synchronization signal group 1:

[0189] The position of the synchronization signal in the synchronization signal set of Group 1: SSB_PositioninBurst1 = '11110000';

[0190] The period of the synchronization signal for group 1 is 20ms;

[0191] The transmission power of the synchronization signal in Group 1 is 40dBm.

[0192] Configuration parameter group 2 for synchronization signal group 1:

[0193] The position of the synchronization signal in the synchronization signal set of Group 1: SSB_PositioninBurst1 = '11110000';

[0194] The period of the synchronization signal for Group 1 is 80ms;

[0195] The transmission power of the synchronization signal in Group 1 is 40dBm.

[0196] Configuration parameter group 3 for synchronization signal group 1:

[0197] The position of the synchronization signal in the synchronization signal set of Group 1: SSB_PositioninBurst1 = '11110000';

[0198] The period of the synchronization signal for group 1 is 160ms;

[0199] The transmission power of the synchronization signal in Group 1 is 20dBm.

[0200] Configuration parameter group 1 for synchronization signal group 2:

[0201] The position of the synchronization signal in the synchronization signal set of Group 2: SSB_PositioninBurst2 = '00001111';

[0202] The period of the synchronization signal for group 2 is 20ms;

[0203] The transmission power of the synchronization signal in group 2 is 40dBm.

[0204] Configuration parameters for synchronization signal group 2:

[0205] The position of the synchronization signal in the synchronization signal set of Group 2: SSB_PositioninBurst2 = '00001111';

[0206] The period of the synchronization signal for group 2 is 80ms;

[0207] The transmission power of the synchronization signal in group 2 is 40dBm.

[0208] Configuration parameter group 3 for synchronization signal group 2:

[0209] The position of the synchronization signal in the synchronization signal set of Group 2: SSB_PositioninBurst2 = '00001111';

[0210] The period of the synchronization signal for group 2 is 160ms;

[0211] The transmission power of the synchronization signal in group 2 is 20dBm.

[0212] Corresponding to this type of system message configuration, as shown in Table 2, the first signaling includes the following information fields:

[0213] Table 2

[0214] At this time, the first signaling instruction indicates that the SSB of synchronization signal packet 1 is transmitted using the parameters of configuration 1; the SSB of synchronization signal packet 2 is transmitted using the parameters of configuration 3.

[0215] Alternatively, the first signaling in this embodiment can also be paging signaling.

[0216] Example 2:

[0217] The terminal receives a synchronization signal sent by the base station. After completing synchronization based on the received synchronization signal, the terminal obtains the physical broadcast channel corresponding to this synchronization signal and determines the synchronization signal index (represented as SSB_index) to be 2. According to the indication of the physical broadcast channel, the terminal receives a first signaling, which is used to schedule system messages. The terminal receives the system message scheduled by the first signaling. The system message indicates a synchronization signal set containing up to 8 synchronization signals, and this set contains two synchronization signal groups. The specific configuration is as follows:

[0218] Synchronization signal group 1 configuration:

[0219] The position of the synchronization signal in the synchronization signal set of Group 1: SSB_PositioninBurst1 = '11110000';

[0220] The period of the synchronization signal for group 1 is 20ms;

[0221] The transmission power of the synchronization signal in Group 1 is 40dBm.

[0222] Synchronization signal group 2 configuration:

[0223] The position of the synchronization signal in the synchronization signal set of Group 2: SSB_PositioninBurst2 = '00001111';

[0224] The period of the synchronization signal for group 2 is 160ms;

[0225] The transmission power of the synchronization signal in group 2 is 40dBm.

[0226] Based on the instructions in the aforementioned system message, the terminal determines that the synchronization signal for packet 1 will be transmitted with a period of 20ms, and the synchronization signal for packet 2 will be transmitted with a period of 160ms. The terminal accesses the cell based on the synchronization signal with index 2 transmitted within 20ms.

[0227] When the base station adjusts the SSB packet period, the system messages will be updated accordingly. For example, after the synchronization signal period of synchronization signal packet 2 is adjusted to 20ms, the system message broadcast by the base station is as follows:

[0228] Synchronization signal group 1 configuration:

[0229] The position of the synchronization signal in the synchronization signal set of Group 1: SSB_PositioninBurst1 = '11110000';

[0230] The period of the synchronization signal for group 1 is 20ms;

[0231] The transmission power of the synchronization signal in Group 1 is 40dBm.

[0232] Synchronization signal group 2 configuration:

[0233] The position of the synchronization signal in the synchronization signal set of Group 2: SSB_PositioninBurst2 = '00001111';

[0234] The period of the synchronization signal for group 2 is 20ms;

[0235] The transmission power of the synchronization signal in group 2 is 40dBm.

[0236] Example 3:

[0237] Assuming the terminal accesses the cell using the method described in Example 1, it is determined that the synchronization signal for Packet 1 is transmitted with a period of 20ms, and the synchronization signal for Packet 2 is transmitted with a period of 160ms. The terminal receives a second signaling, which is used to indicate the activation / deactivation of the TRP. In this example, the identifier for the reference signal is the Tracking Reference Signal (TRS) resource index, and the identifier for measurement reporting is the CSI reporting index. The second signaling includes the following information fields:

[0238] Synchronization signal group indicator: Indicates the group number of the synchronization signal;

[0239] Synchronization signal period indicator: indicates the period of the synchronization signal corresponding to the synchronization signal group number;

[0240] The TRS resource index is the TRS identifier (ID) of the activated TRS resource.

[0241] CSI reporting index, which is the ID corresponding to the CSI report activated by the activation indicator;

[0242] Activation / deactivation indication, which can be used to activate the TRP corresponding to the synchronization signal packet, and deactivation indication can be used to deactivate the TRP corresponding to the synchronization signal packet.

[0243] For example, the second signaling indicated by the base station is shown in Table 3:

[0244] Table 3

[0245] In one implementation, it is assumed that synchronization signal group number 0 corresponds to synchronization signal group 1 and TRP 0; synchronization signal group number 1 corresponds to synchronization signal group 2 and TRP 1. Both TRS resources and CSI reporting are configured via higher-layer signaling. For example, 256 TRS resources and 16 CSI reports are configured. The aforementioned second signaling instructs the activation of TRP 1, and the synchronization signal period of group 2 is adjusted to 20ms. This indicates that TRP 1, which was originally in energy-saving mode, is now switched to normal operating mode. Simultaneously, the TRS signal transmission with TRS ID 30 is activated, and the CSI reporting with report ID 12 is activated.

[0246] In another implementation, the TRS resource can be multiple resources and / or the CSI report can be multiple reports. Thus, the second signaling is used to activate a group of TRS resources and / or to activate a group of CSI reports. For example, the system is configured with TRS resource groups. Each TRS resource group contains multiple TRS resources. Similarly, the system is configured with CSI trigger states, each CSI trigger state associated with multiple CSI reports. Assume 3 bits are used to correspond to 8 CSI trigger states. In this case, the second signaling is as shown in Table 4:

[0247] Table 4

[0248] At this time, it indicates that multiple TRS resources corresponding to TRS resource group index 5 are activated, and the CSI trigger state corresponding to 000 is triggered at the same time.

[0249] After receiving the CSI feedback from the terminal, the base station schedules the user to perform uplink and downlink transmission.

[0250] Example 4:

[0251] The terminal operates in accordance with Embodiment 3, determining that the synchronization signal for Packet 1 is transmitted with a period of 20ms, and the synchronization signal for Packet 2 is also transmitted with a period of 20ms. The terminal receives a second signaling message, which indicates the activation / deactivation of the TRP. This second signaling message includes the following information fields:

[0252] Synchronization signal group indicator: Indicates the group number of the synchronization signal;

[0253] Synchronization signal period indicator: indicates the period of the synchronization signal corresponding to the synchronization signal group number;

[0254] The TRS resource index is the TRS ID of the activated TRS resource;

[0255] CSI reporting index, which is the ID corresponding to the CSI report activated by the activation indicator;

[0256] Activation / deactivation indication, which can be used to activate the TRP corresponding to the synchronization signal packet, and deactivation indication can be used to deactivate the TRP corresponding to the synchronization signal packet.

[0257] For example, the second signaling indicated by the base station is shown in Table 5:

[0258] Table 5

[0259] Assume that synchronization signal group number 0 corresponds to synchronization signal group 1 and TRP 0; synchronization signal group number 1 corresponds to synchronization signal group 2 and TRP 1. Both TRS resources and CSI reporting are configured via higher-layer signaling. For example, 256 TRS resources and 16 CSI reporting points are configured. The second signaling instruction mentioned above indicates that TRP0 is deactivated, and the synchronization signal period of group 1 is adjusted to 160ms. This means that TRP0, which was originally in normal operating mode, is now switched to energy-saving operating mode.

[0260] Simultaneously, the TRS transmission and CSI reporting associated with TRP0 are deactivated, which can be understood as stopping TRS transmission and CSI reporting. The TRS resource index field and CSI reporting index field in the second signaling are invalid, and the TRS associated with TRP0 is determined in the following way:

[0261] The relationship between the TRS and the QCL of the synchronization signal is determined. If the TRS is associated with the QCL of the synchronization signal in synchronization signal group 1, then the TRS is associated with TRP0. If the TRS is associated with the QCL of the synchronization signal in synchronization signal group 2, then the TRS is associated with TRP1.

[0262] The CSI reports associated with TRP0 are identified in the following ways:

[0263] The reference signal associated with the CSI report is determined, and the CSI report associated with TRP0 is determined based on the QCL relationship between the reference signal and the synchronization signal. If the reference signal and the synchronization signal in synchronization signal group 1 have a QCL relationship, then the CSI report associated with this reference signal is determined to be a CSI report associated with TRP0. If the reference signal and the synchronization signal in synchronization signal group 2 have a QCL relationship, then the CSI report associated with this reference signal is determined to be a CSI report associated with TRP1.

[0264] Example 5:

[0265] Unlike Embodiments 3 and 4, in addition to the aforementioned information fields, the second signaling also includes a measurement reporting period indication, for example, a CSI reporting period indication. This information field is used to use the synchronization signal in the indicated synchronization signal group as the CSI reporting configuration for all measurement resources. For example, CSI reporting configuration 1 is associated with the synchronization signal in synchronization signal group 1 for beam measurement reporting. The CSI reporting period indicated by the second signaling indicates the reporting period of this CSI reporting configuration 1. In one possible implementation, the base station configures multiple reporting periods for the CSI reporting configuration, such as 5ms, 10ms, 80ms, and 160ms. The second signaling sent by the base station is an activation signaling, and the CSI reporting period field is 2 bits, as shown in Table 6.

[0266] Table 6

[0267] This signaling instructs the terminal to update its reporting period to 5ms for all CSI reporting configurations that use the synchronization signal in synchronization signal group 1 as a measurement resource. Similarly, when the base station sends a second signaling signaling signaling deactivation signaling, this second signaling signaling is shown in Table 7.

[0268] Table 7

[0269] This signaling instructs the terminal to update the reporting period to 160ms for all CSI reporting configurations that use the synchronization signal in synchronization signal group 0 as a measurement resource.

[0270] In another implementation, the base station configures a default reporting period, such as 10ms, for the CSI reporting configuration. When the second signaling sent by the base station is an activation signaling, this second signaling is the same as in Embodiment 3, and the second signaling is shown in Table 8.

[0271] Table 8

[0272] At this time, the CSI reporting uses the default reporting period, which is 10ms.

[0273] When the second signaling sent by the base station is a deactivation signaling, since the TRS resource index field and CSI reporting index field are invalid at this time, the TRS resource index field or CSI reporting index field can be reinterpreted as the CSI reporting cycle indication field. As shown in Table 9:

[0274] Table 9

[0275] This second signaling will reinterpret the CSI reporting index field in the activation signaling as the CSI reporting period field, which instructs the terminal to update the reporting period to 160ms for all CSI reporting configurations that use the synchronization signal in synchronization signal group 0 as a measurement resource.

[0276] In another implementation, the system stipulates that the CSI reporting period is determined by the synchronization signal period of the corresponding synchronization signal group. For example, if the periods of the two are the same, the terminal can directly determine the CSI reporting period according to the second signaling instruction in Embodiment 3 or Embodiment 4.

[0277] Furthermore, the CSI reporting period in this embodiment may include the value of the reporting period and offset information, which is the offset of the subframe / time slot.

[0278] In the above-described scheme of this disclosure embodiment, a set of synchronization signals is divided into multiple synchronization signal groups. Different synchronization signal groups correspond to different configuration information, and different synchronization signal groups can correspond to different TRPs in the same cell. Thus, the aforementioned first information enables the terminal to transmit synchronization signals on different TRPs according to different configuration information, and / or enables the terminal to realize measurement reporting and / or reference signal transmission on some TRPs. This allows the terminal to enable or disable some TRPs in the same cell for different traffic volumes on TRPs, thereby helping to reduce the energy consumption of the network and the terminal.

[0279] It should be noted that the method for transmitting synchronization signal configuration information executed by the network device is the same as the method for transmitting synchronization signal configuration information executed by the terminal described above. The specific interaction process between the two has been described in detail in the terminal-side embodiment, and will not be repeated here.

[0280] In another embodiment of Examples 1 to 5, a synchronization signal group may further include only one synchronization signal from the synchronization signal set. The other processes are the same and will not be repeated here.

[0281] As shown in Figure 3, this embodiment of the present disclosure provides a device for transmitting synchronization signal configuration information, applied to a terminal, including a memory 320, a transceiver 300, and a processor 310;

[0282] The memory 320 is used to store computer programs; the transceiver 300 is used to send and receive data under the control of the processor 310; the processor 310 is used to read the computer program in the memory 320 and perform the following operations:

[0286] A second signaling instruction is used to indicate the activation of at least one of the transmission of measurement reporting and reference signals corresponding to the first synchronization signal group; or, the second signaling instruction is used to indicate the deactivation of at least one of the transmission of measurement reporting and reference signals corresponding to the second synchronization signal group; wherein the first synchronization signal group and the second synchronization signal group are synchronization signal groups in the synchronization signal set, and the measurement reporting includes measurement reporting of channel state information.

[0287] In Figure 3, the bus architecture can include any number of interconnected buses and bridges, specifically linking various circuits of one or more processors represented by processor 310 and memory represented by memory 320. The bus architecture can also link various other circuits such as peripheral devices, voltage regulators, and power management circuits, which are well known in the art and therefore will not be described further herein. The bus interface provides an interface. The transceiver 300 can be multiple components, including transmitters and receivers, providing a unit for communicating with various other devices over a transmission medium, including wireless channels, wired channels, optical fibers, etc. For different user equipment, the user interface 330 can also be an interface capable of connecting external or internal devices, including but not limited to keypads, displays, speakers, microphones, joysticks, etc.

[0288] The processor 310 is responsible for managing the bus architecture and general processing, while the memory 320 can store the data used by the processor 310 during operation.

[0289] In some implementations, the processor 310 may be a central processing unit (CPU), an application-specific integrated circuit (ASIC), a field-programmable gate array (FPGA), or a complex programmable logic device (CPLD), and the processor may also adopt a multi-core architecture.

[0290] The processor executes any of the methods described in the embodiments of this disclosure by invoking a computer program stored in memory, according to the obtained executable instructions. The processor and memory may also be physically separated.

[0291] In some implementations, the configuration information of the synchronization signal group includes at least one of the following configuration parameters: the index of the synchronization signal; the position of the synchronization signal in the synchronization signal set; the period of the synchronization signal; and the transmission power of the synchronization signal.

[0292] In some implementations, the configuration information of the synchronization signal group includes a configuration parameter group, which includes at least two configuration parameters, and each configuration parameter includes one or more parameter values;

[0293] Alternatively, the configuration information of the synchronization signal group may include at least two configuration parameter groups, and each configuration parameter group may include a parameter value.

[0294] In some implementations, when the configuration information of the synchronization signal group includes a configuration parameter group, the first signaling is used to indicate that the parameter value of the first configuration parameter is the first parameter value.

[0295] Alternatively, if the configuration information of the synchronization signal group includes at least two configuration parameter groups, the first signaling is used to indicate the index of the configuration parameter group corresponding to the first parameter value.

[0296] In some implementations, the first configuration parameter includes at least one of the period of the synchronization signal and the transmission power of the synchronization signal.

[0297] In some implementations, the second signaling includes:

[0299] A synchronization signal packet indicator, wherein the synchronization signal packet indicator is used to indicate the first synchronization signal packet or the second synchronization signal packet;

[0300] An identification indicator is used to indicate at least one of the identification of a reference signal and the identification of a measurement report.

[0301] In some implementations, the second signaling further includes at least one of the following:

[0302] A period indicator for a synchronization signal, the period indicator being used to indicate the period of the synchronization signal in the first synchronization signal group or the second synchronization signal group;

[0303] Periodic indication of measurement reporting.

[0304] In some implementations, when the second signaling includes a deactivation indication, the reference signal corresponding to the second synchronization signal packet has a quasi-co-location (QCL) relationship with the synchronization signal in the second synchronization signal packet.

[0305] In some implementations, when the second signaling includes a deactivation indication, the measurement report corresponding to the second synchronization signal packet includes a measurement report of first channel state information, wherein the reference signal associated with the first channel state information is the synchronization signal in the second synchronization signal packet, or the reference signal associated with the first channel state information has a QCL relationship with the synchronization signal in the second synchronization signal packet.

[0306] In some implementations, the activation indication corresponds to different Radio Network Temporary Identifier (RNTI) scrambling information.

[0307] In some implementations, the processor further performs the following steps:

[0308] When the second signaling includes a periodic indication for the measurement reporting, the measurement resource for the measurement reporting is determined based on the synchronization signal in the first synchronization signal group or the second synchronization signal group.

[0309] In some implementations, the synchronization signal includes a primary synchronization signal and a secondary synchronization signal;

[0310] Alternatively, the synchronization signal may include a primary synchronization signal, a secondary synchronization signal, and a broadcast channel.

[0311] In some implementations, the first signaling is used to schedule resources for the system message, or is a paging instruction, or is higher-level signaling.

[0312] It should be noted that the apparatus provided in this embodiment can implement all the method steps implemented in the above embodiment of the method for transmitting synchronization signal configuration information applied to a terminal, and can achieve the same technical effect. Therefore, the parts and beneficial effects that are the same as those in the method embodiment will not be described in detail here.

[0313] As shown in Figure 4, this embodiment of the present disclosure also provides a device for transmitting synchronization signal configuration information, including a memory 420, a transceiver 400, and a processor 410;
