Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0025] The terms "first," "second," etc., used in the specification and claims of this application are used to distinguish similar objects and not to describe a specific order or sequence. It should be understood that such use of data can be interchanged where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first," "second," etc., are generally of the same class and the number of objects is not limited; for example, a first object can be one or more. Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0026] The communication methods, devices, equipment, storage media, and program products provided in this application will be described in detail below with reference to the accompanying drawings and through specific embodiments and application scenarios.

[0027] Please see Figure 1 , Figure 1 This is a flowchart of a communication method provided in an embodiment of this application. The method is applied to a terminal, such as... Figure 1 As shown, the method includes the following steps:

[0028] Step 11: The terminal receives first information, which is used to indicate or activate SSB configuration.

[0029] In this embodiment of the application, the first information may be, but is not limited to, Radio Resource Control (RRC) signaling, Medium Access Control Control Element (MAC CE), or Downlink Control Information (DCI).

[0030] The aforementioned receiving of the first information may include: the terminal receiving the first information from the network-side device.

[0031] In one alternative implementation, the first information is used to indicate or activate a set of SSB configurations.

[0032] Optionally, the first information may include at least one of the following:

[0033] The sequence number of the SSB configuration is the sequence number that indicates or activates the SSB configuration.

[0034] The identifier ID of the secondary cell (SCell), such as a secondary cell that transmits on-demand SSBs, that is, an SSB that is transmitted on the secondary cell based on the configuration that indicates or activates the SSB;

[0035] SSB cycle; that is, the SSB cycle corresponding to the SSB configuration indicated or activated by the first information, which can be understood as the SSB transmission cycle;

[0036] The first time interval; specifically, the SSB activation time interval, is used to determine the SSB transmission activation time, etc.

[0037] The solution provided in this application allows the terminal to select a suitable SSB configuration, thereby meeting the measurement reporting requirements.

[0038] Optionally, before receiving the first information, the communication method in this application embodiment may further include:

[0039] The terminal receives configuration information; the configuration information includes at least one SSB configuration; the first information is used to indicate or activate one SSB configuration from the at least one SSB configuration. The at least one SSB configuration is at least one on-demand SSB configuration, that is, a non-periodic SSB configuration.

[0040] For example, a terminal can receive configuration information via higher-layer RRC signaling. This configuration information may include at least one set of on-demand SSB configurations, as well as periodically occurring SSB configurations.

[0041] Optionally, the SSB configuration may include at least one of the following:

[0042] The sequence number of the SSB configuration; the corresponding SSB configuration can be indicated based on this sequence number;

[0043] SSB cycle, that is, the SSB cycle corresponding to the SSB configuration;

[0044] SSB transmission duration;

[0045] The second time interval; specifically, the SSB activation time interval, is used to determine the SSB transmission activation time, etc.

[0046] SSB transmit power is used to indicate the power used when transmitting / sending an SSB.

[0047] Optionally, the scheme in this application is applicable to energy-saving scenarios in carrier aggregation (CA) networks. In CA network energy-saving scenarios, on-demand SSB transmission on the SCell can increase the SCell sleep time, thereby achieving network energy saving. No SSB transmission occurs during SCell deactivation to reduce network power consumption. When a service arrives, the base station can instruct / activate on-demand SSB transmission (i.e., instruct / activate the corresponding SSB configuration) while sending SCell activation signaling to complete synchronization, measurement, etc., during SCell activation. After activation, the SSB can still be used for terminal synchronization and measurement. When there is no service for a period of time, the base station can disable on-demand SSB transmission to reduce network power consumption, and then instruct / activate on-demand SSB transmission again when a new service arrives. Furthermore, during SCell deactivation, long-cycle SSBs can be transmitted by configuring the instruction / activation of long-cycle (e.g., greater than 20ms) SSBs to reduce network power consumption. When a service arrives, the base station can switch the SSB period to a short period (e.g., less than or equal to 20ms) while sending the SCell activation signaling, in order to complete synchronization and measurement during and after SCell activation. When there is no service for a period of time, the base station can switch the SSB period to a long period to reduce network power consumption, and then switch the SSB period back to a short period when a new service arrives.

[0048] Based on the above, the SSB on the SCell is intermittent, but currently only one Channel State Information (CSI) reporting period is typically configured. This leads to a mismatch between the CSI reporting period and the SSB transmission period, resulting in either untimely CSI reporting or wasted reporting resources. To address this issue, this application proposes associating different CSI reporting periods with different SSB configurations, i.e., different CSI reporting periods are associated with different SSB periods. This ensures that the CSI reporting period and the SSB transmission period are compatible, avoiding the untimely CSI reporting caused by a single reporting period being longer than the SSB transmission period, or the wasted reporting resources caused by a single reporting period being shorter than the SSB transmission period.

[0049] Optionally, the communication method in the embodiments of this application may further include:

[0050] The terminal receives a CSI reporting configuration; the CSI reporting configuration includes at least one reporting period, and the at least one reporting period satisfies the following condition: different reporting periods are associated with different SSB configurations. This association of different reporting periods with different SSB configurations can be understood as different reporting periods being associated with different SSB periods. Thus, after indicating or activating an SSB configuration, CSI reporting can be performed using the reporting period associated with the SSB period included in that SSB configuration, thereby ensuring that the CSI reporting period and the SSB transmission period are matched, avoiding untimely CSI reporting or wasted reporting resources.

[0051] It should be noted that different reporting periods can be associated with different SSB configurations either explicitly or implicitly. For example, in implicit configuration, the SSB periods from largest to smallest can be associated with the CSI reporting periods from largest to smallest.

[0052] In one alternative implementation, the terminal can receive CSI reported configuration via RRC signaling.

[0053] In one optional implementation, the SSB time-domain configuration in the CSI reporting configuration is associated with the SSB configuration indicated / activated by the first information.

[0054] Optionally, the CSI reporting configuration is associated with a first resource set, and the SSB transmission timing corresponding to the first resource set is the same as the SSB transmission timing corresponding to the SSB configuration indicated or activated by the first information. This allows the CSI reporting cycle and the SSB transmission cycle to be matched, avoiding the inability to report CSI in a timely manner or the waste of reporting resources.

[0055] Optionally, the first resource set may contain one or more SSB indexes so that CSI reporting can be performed using the SSB corresponding to the SSB index.

[0056] Optionally, after the above-described configuration for receiving CSI reports, the communication method in this embodiment may further include:

[0057] The terminal obtains the CSI reporting amount based on the first SSB transmission timing; wherein the first SSB transmission timing satisfies at least one of the following:

[0058] (1) The first SSB transmission timing is the SSB transmission timing that is before the CSI reference resource and is the closest to the CSI reference resource during the SSB transmission period;

[0059] (2) The first SSB transmission timing is the SSB transmission timing closest to the CSI reference resource that is prior to the CSI reference resource and during the effective period of the SSB configuration indicated or activated by the first information;

[0060] (3) The first SSB transmission timing is the SSB transmission timing that is before the CSI reference resource and is the closest to the CSI reference resource during the effective period of the first information;

[0061] (4) The first SSB transmission timing is the SSB transmission timing before the CSI reference resource and during the effective period of the SSB transmission;

[0062] (5) The first SSB transmission timing is an SSB transmission timing prior to the CSI reference resource and within the effective period of the first information indication or activated SSB configuration.

[0063] (6) The first SSB transmission timing is the SSB transmission timing before the CSI reference resource and during the effective period of the first information.

[0064] It should be noted that the CSI reference resource is associated with CSI reporting. The CSI reference resource can be a time slot obtained by adding a time offset to the CSI reporting time slot. In this way, by using (1) to (6) above, the SSB transmission timing for obtaining / calculating CSI reporting volume can be accurately determined, thereby accurately obtaining the CSI reporting volume.

[0065] In one alternative implementation, the terminal may obtain the CSI reporting volume based on the first SSB transmission timing when the received CSI reporting configuration includes the timeRestrictionForChannelMeasurements parameter.

[0066] Optionally, for any one of (1) to (6) above, the effective period of the SSB transmission, the effective period of the SSB configuration indicated or activated by the first information, and the effective period of the first information may satisfy at least one of the following:

[0067] 1) Starting from the time unit where the first information is located plus the first duration, until the end of SSB transmission or deactivation; the end of SSB transmission can be the end after the expiration of the SSB transmission duration, the deactivation of SSB transmission can be based on explicit deactivation signaling to deactivate SSB transmission, and the end of SSB transmission or deactivation can be the end of all SSB transmissions or deactivation; the time unit can be selected as a time slot, symbol, subframe, or frame, etc.

[0068] 2) Starting from the time unit where the Hybrid Automatic Repeat Request (HARQ) feedback of the first information is located, plus the first duration, until the end of SSB transmission or deactivation; the end of SSB transmission can be the end after the expiration of the SSB transmission duration, the deactivation of SSB transmission can be based on explicit deactivation signaling to deactivate SSB transmission, and the end or deactivation of SSB transmission can be the end or deactivation of all SSB transmissions; the time unit can be selected as a time slot, symbol, subframe, or frame, etc.

[0069] 3) The transmission begins from the second SSB transmission timing point and ends when the SSB transmission ends or is deactivated; the second SSB transmission timing point is the first SSB transmission timing point after the time unit where the first information is located plus the first duration; the end of the SSB transmission can be the end after the expiration of the SSB transmission duration, the deactivation of the SSB transmission can be based on explicit deactivation signaling to deactivate the SSB transmission, and the end or deactivation of the SSB transmission can be the end or deactivation of all SSB transmissions; the time unit can be selected as a time slot, symbol, subframe, or frame, etc.

[0070] 4) The transmission begins at the third SSB transmission opportunity and continues until the SSB transmission ends or is deactivated; the third SSB transmission opportunity is the first SSB transmission opportunity after the time unit where the HARQ feedback of the first information is located plus the first duration. The end of the SSB transmission can be the end after the expiration of the SSB transmission duration, and the deactivation of the SSB transmission can be based on explicit deactivation signaling to deactivate the SSB transmission. The end or deactivation of the SSB transmission can be the end or deactivation of all SSB transmissions; the time unit can be selected as a time slot, symbol, subframe, or frame, etc.

[0071] Optionally, the first duration can be understood as the SSB effective time interval, and can be any of the following:

[0072] The first information includes a first time interval;

[0073] The first information indicates or activates a second time interval contained in the SSB configuration.

[0074] The processing time of the first information; for example, if the first information is MAC CE, then the first duration is the processing time of MAC CE (e.g., 3ms); or, if the first information is DCI, then the first duration is the processing time of DCI.

[0075] Optionally, when an SSB transmission is indicated / activated, if the terminal receives at least one SSB transmission opportunity before the CSI reference resource and during the effective period of the SSB transmission, a CSI report is made; otherwise, the report is discarded.

[0076] Optionally, the communication method in the embodiments of this application may further include at least one of the following:

[0077] (a) If no SSB transmission opportunity is received before the CSI reference resource and during the effective period of the SSB transmission, the terminal discards the CSI report;

[0078] (b) If no SSB transmission opportunity is received before the CSI reference resource and during the effective period of the first information indication or activated SSB configuration, the terminal discards the CSI report;

[0079] (c) If no SSB transmission opportunity is received before the CSI reference resource and during the effective period of the first information, the terminal discards the CSI report.

[0080] It should be noted that the aforementioned timing of receiving SSB transmissions can be understood as receiving the SSB during the SSB transmission period. This clarifies the reporting discard rules and avoids invalid reporting during SSB shutdown.

[0081] Considering that SSBs on SCells are intermittent, but for SSB measurements, currently only one evaluation cycle and / or measurement cycle is typically configured. This leads to a mismatch between the evaluation / measurement cycle and the SSB transmission cycle, resulting in either an excessively short evaluation / measurement cycle or excessively long measurement latency, which in turn affects the SSB measurement results. To address this issue, this application proposes the following solution.

[0082] Optionally, after receiving the first information, the communication method in this application embodiment may further include:

[0083] The terminal performs SSB measurements based on the SSB configuration and a first evaluation period and / or a first measurement period. The first evaluation period may include multiple SSB periods; that is, the number of SSB periods to be measured during SSB measurements can be determined based on the first evaluation period and the SSB periods included in the indicated / activated SSB configuration. The first measurement period may also include multiple SSB periods; that is, the number of SSB periods to be measured during SSB measurements can be determined based on the first measurement period and the SSB periods included in the indicated / activated SSB configuration.

[0084] In this way, by reasonably setting the first evaluation cycle and / or the first measurement cycle, the evaluation / measurement cycle and the SSB transmission cycle can be adapted, thereby enabling the terminal to quickly perform the evaluation and measurement of relevant measurement steps, thus reducing measurement latency.

[0085] For example, the first evaluation period can be an evaluation period for layer 1 / layer 3 measurements, such as the evaluation period for candidate beam detection CBD. The first measurement period can be a layer 1 measurement period, such as a beam management measurement period based on layer 1 reference signal received power (L1-RSRP).

[0086] Optionally, the first evaluation period and / or the first measurement period may satisfy at least one of the following:

[0087] (I) The first evaluation period and / or the first measurement period are equal to Max(first parameter, second parameter * first period).

[0088] When the first evaluation period and / or the first measurement period are defined in (I), the first power-saving mechanism of the terminal system may be in a disabled / deactivated state. For example, this first power-saving mechanism may be a Connection Discontinuous Reception (C-DRX) mechanism or a Discontinuous Transmission (DTX) mechanism.

[0089] Optionally, either the first parameter or the second parameter can be a predefined value or a value configured by the network-side device.

[0090] In one possible implementation, the second parameter can be 1, that is: the first evaluation period and / or the first measurement period is equal to Max(first parameter, first period).

[0091] Optionally, either the first parameter or the second parameter may be determined based on at least one of the following: a first SSB measurement window, a first measurement interval, and a CSI reporting cycle; wherein at least one of the first SSB measurement window, the first measurement interval, and the CSI reporting cycle is associated with the SSB configuration indicated or activated by the first information.

[0092] Optionally, the first period can be any of the following: the SSB period corresponding to the SSB configuration indicated or activated by the first information, the maximum value between the SSB period corresponding to the SSB configuration indicated or activated by the first information and the periodic SSB period. A periodic SSB can be understood as a periodic, frequently occurring SSB that does not require dynamic activation / deactivation indication.

[0093] (II) The first evaluation period and / or the first measurement period equals Max(third parameter, fourth parameter * first period, fifth parameter * second period).

[0094] When the first evaluation period and / or the first measurement period are defined in (II), the first power-saving mechanism of the terminal system may be in an on / activated state. For example, this first power-saving mechanism may be a C-DRX mechanism or a cell DTX mechanism.

[0095] Optionally, the first period can be any of the following: the SSB period corresponding to the SSB configuration indicated or activated by the first information, the maximum value between the SSB period corresponding to the SSB configuration indicated or activated by the first information and the periodic SSB period. A periodic SSB can be understood as a periodic, frequently occurring SSB that does not require dynamic activation / deactivation indication.

[0096] Optionally, the second period is the configuration period of the first energy-saving mechanism. For example, the second period is less than or equal to a first threshold; the first threshold can be a predefined value or a value configured by the network-side device.

[0097] Optionally, any one of the third, fourth, and fifth parameters can be a predefined value or a value configured by the network-side device.

[0098] In one possible implementation, the fourth parameter and / or the fifth parameter can be 1.

[0099] In one possible implementation, the fourth parameter and the fifth parameter are equal, that is, the above (II) can be described as: the first evaluation period and / or the first measurement period is equal to Max(the third parameter, the fourth parameter * Max(the first period, the second period)).

[0100] Optionally, any one of the third, fourth, and fifth parameters may be determined based on at least one of the following: a first SSB measurement window, a first measurement interval, and a CSI reporting cycle; wherein at least one of the first SSB measurement window, the first measurement interval, and the CSI reporting cycle is associated with the SSB configuration indicated or activated by the first information.

[0101] (III) The first evaluation cycle and / or the first measurement cycle are equal to the sixth parameter * the second cycle.

[0102] When the first evaluation period and / or the first measurement period are defined under (III), the first power-saving mechanism of the terminal system may be in an on / activated state. For example, this first power-saving mechanism may be a C-DRX mechanism or a cell DTX mechanism.

[0103] Optionally, the second period is the configuration period of the first energy-saving mechanism. For example, the second period is greater than or equal to a first threshold; the first threshold can be a predefined value or a value configured by the network-side device.

[0104] Optionally, the sixth parameter can be a predefined value or a value configured by the network-side device.

[0105] In one possible implementation, the sixth parameter can be 1, that is: the first evaluation period and / or the first measurement period is equal to the second period.

[0106] Optionally, the sixth parameter may be determined based on at least one of the following: a first SSB measurement window, a first measurement interval, and a CSI reporting cycle; wherein at least one of the first SSB measurement window, the first measurement interval, and the CSI reporting cycle is associated with the SSB configuration indicated or activated by the first information.

[0107] The present application will now be described in conjunction with specific embodiments.

[0108] Example 1

[0109] In this first embodiment, the network side configures SCell1 to include one set of SSB configurations via higher-layer RRC signaling. The corresponding contents are: SSB configuration number 1, SSB period = 20ms, SSB activation interval = 10ms. This SSB configuration can be understood as an ondemand SSB configuration.

[0110] like Figure 2 As shown, initially, SCell1 has no SSB transmission, and SCell1 is inactive for UE1. When the base station detects that a large amount of downlink data is about to arrive for UE1, it activates SCell1 for UE1 in time slot n1, and simultaneously instructs / activates the SSB configuration corresponding to SSB configuration sequence number 1 on SCell1 to perform the corresponding SSB transmission. In time slot n2, assuming the base station detects that UE1 has no downlink data for a period of time, it instructs to deactivate the SSB configuration corresponding to SSB configuration sequence number 1. When new downlink data arrives in time slot n3, it instructs / activates the SSB configuration corresponding to SSB configuration sequence number 1 again.

[0111] In addition, the base station can configure periodic CSI reporting based on SSB for UE1 in time slot n1+3, with a reporting period of 20ms. In this case, the reporting in time slots n2-10 can be reported normally, and the reporting in time slot n2+10 can still receive an SSB transmission opportunity before the CSI reference resource and can be reported normally. However, the reporting in time slot n2+30 does not receive an SSB transmission opportunity before the CSI reference resource and is discarded.

[0112] Example 2

[0113] In this second embodiment, the network side configures SCell1 with two sets of SSB configurations via higher-layer RRC signaling. The corresponding contents are as follows: 1) SSB configuration sequence number 1, SSB period = 20ms, SSB activation interval = 10ms; 2) SSB configuration sequence number 2, SSB period = 40ms, SSB activation interval = 10ms. This SSB configuration can be understood as an on-demand SSB configuration.

[0114] like Figure 3 As shown, when SCell1 is deactivated, SSB configuration 2 is activated by default. When the base station detects that a large amount of downlink data is about to arrive for UE1, it activates SCell1 for UE1 in time slot n1, and simultaneously instructs / activates the SSB configuration corresponding to SSB configuration sequence number 1 on SCell1 to perform the corresponding SSB transmission. In time slot n2, assuming the base station detects that UE1 has no downlink data for a period of time, it instructs to activate the SSB configuration corresponding to SSB configuration sequence number 2, that is, switches the SSB cycle to a longer cycle. When new downlink data arrives in time slot n3, it again instructs / activates the SSB configuration corresponding to SSB configuration sequence number 1, that is, switches the SSB cycle to a shorter cycle.

[0115] In addition, the base station can configure SSB-based periodic CSI reporting for UE1 in time slot n1+3. There are two reporting periods: a 20ms reporting period associated with SSB configuration number 1 and a 40ms reporting period associated with SSB configuration number 2. The terminal uses a 20ms reporting period for reporting between time slots n1+3 and n2, a 40ms reporting period for reporting between time slots n2+3 and n3, and a 20ms reporting period for reporting after time slot n3+3.

[0116] Please see Figure 4 , Figure 4 This is a flowchart illustrating a communication method provided in an embodiment of this application. This method is applied to a network-side device, such as... Figure 4 As shown, the method includes the following steps:

[0117] Step 41: The network-side device sends first information to the terminal; the first information is used to indicate or activate the SSB configuration.

[0118] In this embodiment of the application, the first information may be, but is not limited to, RRC signaling, MAC CE, or DCI.

[0119] In one alternative implementation, the first information is used to indicate or activate a set of SSB configurations.

[0120] Optionally, the first information may include at least one of the following:

[0121] The sequence number of the SSB configuration is the sequence number that indicates or activates the SSB configuration.

[0122] The identifier ID of the secondary cell (SCell), such as a secondary cell that transmits on-demand SSBs, that is, an SSB that is transmitted on the secondary cell based on the configuration that indicates or activates the SSB;

[0123] SSB cycle; that is, the SSB cycle corresponding to the SSB configuration indicated or activated by the first information, which can be understood as the SSB transmission cycle;

[0124] The first time interval; specifically, the SSB activation time interval, is used to determine the SSB transmission activation time, etc.

[0125] The solution provided in this application allows the terminal to select a suitable SSB configuration, thereby meeting the measurement reporting requirements.

[0126] Optionally, before sending the first information to the terminal as described above, the communication method in this application embodiment may further include:

[0127] The network-side device sends configuration information to the terminal; the configuration information includes at least one SSB configuration; the first information is used to indicate or activate one SSB configuration from the at least one SSB configuration. The at least one SSB configuration is at least one on-demand SSB configuration, that is, a non-periodic SSB configuration.

[0128] For example, network-side devices can send configuration information via higher-layer RRC signaling. This configuration information may include at least one set of on-demand SSB configurations, as well as periodically frequently transmitted SSB configurations.

[0129] Optionally, the SSB configuration may include at least one of the following:

[0130] The sequence number of the SSB configuration; the corresponding SSB configuration can be indicated based on this sequence number;

[0131] SSB cycle, that is, the SSB cycle corresponding to the SSB configuration;

[0132] SSB transmission duration;

[0133] The second time interval; specifically, the SSB activation time interval, is used to determine the SSB transmission activation time, etc.

[0134] SSB transmit power is used to indicate the power used when transmitting / sending an SSB.

[0135] Optionally, the communication method in the embodiments of this application may further include:

[0136] The network-side device sends a CSI reporting configuration to the terminal. This CSI reporting configuration includes at least one reporting period, where different reporting periods are associated with different SSB configurations. This association of different reporting periods with different SSB configurations can be understood as different reporting periods being associated with different SSB periods. Thus, after indicatively activating an SSB configuration, CSI reporting can be performed using the reporting period associated with that SSB period, thereby ensuring that the CSI reporting period and the SSB transmission period are matched, avoiding untimely CSI reporting or wasted reporting resources.

[0137] Optionally, the CSI reporting configuration is associated with a first resource set, and the SSB transmission timing corresponding to the first resource set is the same as the SSB transmission timing corresponding to the SSB configuration indicated or activated by the first information. This allows the CSI reporting cycle and the SSB transmission cycle to be matched, avoiding the inability to report CSI in a timely manner or the waste of reporting resources.

[0138] Optionally, the first resource set may contain one or more SSB indexes so that CSI reporting can be performed using the SSB corresponding to the SSB index.

[0139] It should be noted that the communication method provided in this application embodiment can be executed by a communication device or a control module in the communication device for executing the communication method.
