Based on the embodiments in the present disclosure, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the protection scope of the present disclosure.

In addition, "and / or" in the specification and claims indicates at least one of the connected objects, and the character " / ", generally indicates that the objects before and after are in a "or" relationship.

[0028] The communication method, device, equipment, storage medium and program product provided by the embodiments of the present disclosure will be described in detail below in combination with the drawings, specific embodiments and application scenarios.

[0029] Please refer to FIG. 1, which is a flow chart of a communication method provided by an embodiment of the present disclosure, the method is applied to a terminal, as shown in FIG. 1, the method includes the following steps:

[0030] Step 11: The terminal receives first information, the first information is used to indicate or activate SSB configuration.

[0031] In the embodiments of the present disclosure, the first information can be selected from, but not limited to, radio resource control (RRC) signaling, medium access control control element (MAC CE) or downlink control information (DCI) and the like.

[0032] The above receiving first information can include: the terminal receives the first information from a network side device.

[0033] In an optional implementation, the first information is used to indicate or activate a set of SSB configuration.

[0034] Optionally, the first information can include at least one of the following:

[0035] The serial number of the SSB configuration, that is, the serial number of the SSB configuration indicated or activated;

[0036] The identification (ID) of a secondary cell (SCell), such as a secondary cell for transmitting on demand SSB, that is, transmitting SSB on the secondary cell based on the SSB configuration indicated or activated;

[0037] SSB period; that is, the SSB period corresponding to the SSB configuration indicated or activated by the first information, which can be understood as the SSB transmission period;

[0038] The first time interval; the first time interval is specifically a SSB effective time interval, which is used to determine the SSB transmission effective time, etc.

[0039] Through the scheme of the embodiments of the present disclosure, the terminal can select a suitable SSB configuration, and thus the demand of measurement reporting can be met.

[0040] Optionally, before the receiving of the first information, the communication method in the embodiments of the present disclosure can further include:

[0041] The terminal receives configuration information; the configuration information includes at least one set of SSB configurations; and the first information is used to indicate or activate a set of SSB configurations from the at least one set of SSB configurations. The at least one set of SSB configurations is at least one set of on-demand SSB configurations, that is, aperiodic SSB configurations.

[0042] For example, the terminal can receive the configuration information through high-layer RRC signaling. In addition to including at least one set of on-demand SSB configurations, the configuration information can also include periodic and frequently occurring SSB configurations.

[0043] Optionally, the SSB configuration can include at least one of the following:

[0044] The serial number of the SSB configuration; based on the serial number, the corresponding SSB configuration can be indicated;

[0045] The SSB period, that is, the SSB period corresponding to the SSB configuration;

[0046] The SSB transmission duration;

[0047] The second time interval; the second time interval is specifically a SSB effective time interval, which is used to determine the SSB transmission effective time, etc.

[0048] The SSB transmission power, which is used to indicate the power when transmitting / sending the SSB.

[0049] Optionally, the solutions in the present disclosure are applicable to a carrier aggregation (CA) network energy saving scenario, etc. In the CA network energy saving scenario, the on demand SSB transmission on the SCell can increase the SCell sleep time, thereby realizing network energy saving. There is no SSB transmission during SCell deactivation to reduce network energy consumption. When there is traffic, the base station can indicate / activate the on demand SSB transmission (i.e., indicate / activate the corresponding SSB configuration) at the same time as sending the SCell activation signaling, to complete synchronization, measurement, etc. during SCell activation, and the SSB can still be used for terminal synchronization and measurement after the activation. When there is no traffic for a period of time, the base station can turn off the on demand SSB transmission to reduce network energy consumption, and when new traffic arrives, the on demand SSB transmission is indicated / activated again. In addition, during SCell deactivation, a large period (such as greater than 20 ms) SSB can be transmitted by indicating / activating the configuration of the large period SSB to reduce network energy consumption. When there is traffic, the base station can switch the SSB period to a small period (such as less than or equal to 20 ms) by indicating / activating the configuration of the small period SSB at the same time as sending the SCell activation signaling, to complete synchronization, measurement, etc. during SCell activation and after the activation. When there is no traffic for a period of time, the base station can switch the SSB period to a large period to reduce network energy consumption, and when new traffic arrives, the SSB period is switched to a small period again.

[0050] Based on the above, the SSB on the SCell is time-varying, but at present, only one channel state information (CSI) reporting period is usually configured, which will cause the CSI reporting period and the SSB transmission period to be unable to adapt, thereby causing the CSI to be unable to be reported in time or causing the reporting resources to be wasted. To solve this problem, the solutions in the present disclosure propose that different CSI reporting periods are associated with different SSB configurations, that is, different CSI reporting periods are associated with different SSB periods, thereby causing the CSI reporting period and the SSB transmission period to be adapted, avoiding the situation that when a single reporting period is larger than the SSB transmission period, the CSI cannot be reported in time, or the situation that when a single reporting period is smaller than the SSB transmission period, the reporting resources are wasted.

[0051] Optionally, the communication method in the embodiment of the present disclosure can further include:

[0052] The terminal receives a CSI reporting configuration; the CSI reporting configuration comprises at least one reporting period, and the at least one reporting period meets that different reporting periods are associated with different SSB configurations. The association of different reporting periods with different SSB configurations can be understood as the association of different reporting periods with different SSB periods. In this way, after the SSB configuration is indicated or activated, the CSI reporting can be performed by using the reporting period associated with the SSB period contained in the SSB configuration, so that the CSI reporting period and the SSB transmission period are adapted, and the waste of reporting resources caused by the failure to report CSI in time is avoided.

[0053] It should be noted that, for the association of different reporting periods with different SSB configurations, explicit configuration or implicit configuration can be used. For example, when the implicit configuration is used, the SSB periods from large to small can be associated with the CSI reporting periods from large to small in sequence.

[0054] In an optional embodiment, the terminal can receive the CSI reporting configuration through RRC signaling.

[0055] In an optional embodiment, the SSB time domain configuration in the CSI reporting configuration is associated with the SSB configuration indicated / activated by the first information.

[0056] Optionally, the CSI reporting configuration is associated with a first resource set, and the SSB transmission occasion corresponding to the first resource set is the same as the SSB transmission occasion corresponding to the SSB configuration indicated or activated by the first information. In this way, the CSI reporting period and the SSB transmission period are adapted, and the waste of reporting resources caused by the failure to report CSI in time is avoided.

[0057] Optionally, the first resource set can comprise one or more SSB indexes, so as to perform CSI reporting by using the SSB corresponding to the SSB index.

[0058] Optionally, after the CSI reporting configuration is received, the communication method in the embodiment of the present disclosure can further comprise:

[0059] The terminal obtains a CSI reporting quantity according to a first SSB transmission occasion; wherein the first SSB transmission occasion meets at least one of the following conditions:

[0060] (1) the first SSB transmission occasion is the SSB transmission occasion closest to the CSI reference resource before the CSI reference resource and within the SSB transmission effective period;

[0061] (2) the first SSB transmission occasion is the SSB transmission occasion closest to the CSI reference resource before the CSI reference resource and within the effective period of the SSB configuration indicated or activated by the first information;

[0062] (3) the first SSB transmission occasion is the nearest SSB transmission occasion before the CSI reference resource and within the validity duration of the first information;

[0063] (4) the first SSB transmission occasion is the SSB transmission occasion before the CSI reference resource and within the validity duration of SSB transmission;

[0064] (5) the first SSB transmission occasion is the SSB transmission occasion before the CSI reference resource and within the validity duration of the SSB configuration indicated or activated by the first information;

[0065] (6) the first SSB transmission occasion is the SSB transmission occasion before the CSI reference resource and within the validity duration of the first information.

[0066] It is pointed out 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 means of (1) to (6) above, the SSB transmission occasion for obtaining / calculating the CSI reporting quantity can be accurately determined, so that the CSI reporting quantity can be accurately obtained.

[0067] In an optional implementation, the terminal can obtain the CSI reporting quantity according to the first SSB transmission occasion when the timeRestrictionForChannelMeasurements parameter is included in the received CSI reporting configuration.

[0068] Optionally, for (1) to (6) above, any one of the validity duration of SSB transmission, the validity duration of the SSB configuration indicated or activated by the first information, and the validity duration of the first information can satisfy at least one of the following:

[0069] 1) from the time unit where the first information is located plus a first time length, to the end or deactivation of SSB transmission; the end of SSB transmission can be the end after the SSB transmission duration expires, the SSB transmission can be deactivated based on explicit deactivation signaling, the SSB transmission can be ended or deactivated; the time unit can be a time slot, a symbol, a subframe, or a frame, etc.

[0070] 2) from the time unit where the HARQ feedback of the first information is located plus the first time length, to the end of SSB transmission or deactivation; the end of SSB transmission can be the end after the SSB transmission duration expires, the SSB transmission deactivation can be the SSB transmission deactivation based on the explicit deactivation signaling, and the end or deactivation of SSB transmission can be the end or deactivation of all SSB transmissions; the time unit can be selected from a time slot, a symbol, a subframe, a frame, etc.

[0071] 3) from the second SSB transmission occasion to the end of SSB transmission or deactivation; the second SSB transmission occasion is the first SSB transmission occasion after the time unit where the first information is located plus the first time length; the end of SSB transmission can be the end after the SSB transmission duration expires, the SSB transmission deactivation can be the SSB transmission deactivation based on the explicit deactivation signaling, and the end or deactivation of SSB transmission can be the end or deactivation of all SSB transmissions; the time unit can be selected from a time slot, a symbol, a subframe, a frame, etc.

[0072] 4) from the third SSB transmission occasion to the end of SSB transmission or deactivation; the third SSB transmission occasion is the first SSB transmission occasion after the time unit where the HARQ feedback of the first information is located plus the first time length. The end of SSB transmission can be the end after the SSB transmission duration expires, the SSB transmission deactivation can be the SSB transmission deactivation based on the explicit deactivation signaling, and the end or deactivation of SSB transmission can be the end or deactivation of all SSB transmissions; the time unit can be selected from a time slot, a symbol, a subframe, a frame, etc.

[0073] Optionally, the first time length can be understood as a SSB effective time interval, and can be any of the following:

[0074] The first time interval contained in the first information;

[0075] The second time interval contained in the SSB configuration indicated or activated by the first information;

[0076] The processing time of the first information; for example, if the first information is a MAC CE, the first time length is the processing time (such as 3ms) of the MAC CE; or, if the first information is a DCI, the first time length is the processing time of the DCI.

[0077] Optionally, when the SSB transmission is indicated / activated, if the terminal receives at least one SSB transmission occasion before the CSI reference resource and during the SSB transmission effective period, the CSI reporting is performed, otherwise the reporting is discarded.

[0078] Optionally, the communication method in the embodiments of the present disclosure can further include at least one of the following:

[0079] (a) When no SSB transmission occasion is received before the CSI reference resource and within the validity period of the SSB transmission, the terminal discards the CSI report;

[0080] (b) When no SSB transmission occasion is received before the CSI reference resource and within the validity period of the SSB configuration indicated or activated by the first information, the terminal discards the CSI report;

[0081] (c) When no SSB transmission occasion is received before the CSI reference resource and within the validity period of the first information, the terminal discards the CSI report.

[0082] It should be noted that the above-mentioned received SSB transmission occasion can be understood as receiving SSB at the SSB transmission occasion. In this way, the reporting discarding rule can be clearly defined, and invalid reporting during SSB closing can be avoided.

[0083] Considering that SSB on the SCell is sometimes present and sometimes absent, but for SSB measurement, only one evaluation period and / or measurement period is usually configured at present, which will result in the evaluation / measurement period and the SSB transmission period being unable to be adapted, thereby causing the evaluation / measurement period to be too small or the measurement delay to be too large, and further affecting the SSB measurement result. In order to solve this problem, the present disclosure proposes the following scheme.

[0084] Optionally, after receiving the first information, the communication method in the embodiments of the present disclosure can further include:

[0085] The terminal performs SSB measurement according to the SSB configuration and the first evaluation period and / or the first measurement period. The first evaluation period can include multiple SSB periods, that is, according to the first evaluation period and the SSB periods included in the indicated / activated SSB configuration, it can be determined how many SSB periods are measured when performing SSB measurement. The first measurement period can include multiple SSB periods, that is, according to the first measurement period and the SSB periods included in the indicated / activated SSB configuration, it can be determined how many SSB periods are measured when performing SSB measurement.

[0086] In this way, by reasonably setting the first evaluation period and / or the first measurement period, the evaluation / measurement period and the SSB transmission period can be adapted, so that the terminal can quickly perform evaluation and measurement of the related measurement steps, thereby reducing the measurement delay.

[0087] For example, the first evaluation period can be an evaluation period of Layer 1 / Layer 3 measurement, such as a candidate beam detection (CBD) evaluation period. The first measurement period can be a period of Layer 1 measurement, such as a beam management measurement period based on Layer 1 Reference Signal Received Power (L1-RSRP).

[0088] Optionally, the first evaluation period and / or the first measurement period can satisfy at least one of the following:

[0089] (I) The first evaluation period and / or the first measurement period is equal to Max (the first parameter, the second parameter * the first period).

[0090] When the first evaluation period and / or the first measurement period is defined under this (I), a first energy saving mechanism of the terminal system can be in a closed / deactivated state. For example, the first energy saving mechanism can be a Connection Discontinuous Reception (C-DRX) mechanism or a cell Discontinuous Transmission (DTX) mechanism.

[0091] Optionally, any one of the first parameter and the second parameter can be a predefined value or a value configured by a network side device.

[0092] In a possible implementation, the second parameter can be 1, i.e., the first evaluation period and / or the first measurement period is equal to Max (the first parameter, the first period).

[0093] Optionally, any one of the first parameter and the second parameter can be determined according to at least one of the following: a first SSB measurement window, a first measurement interval, and a CSI reporting period; wherein at least one of the first SSB measurement window, the first measurement interval, and the CSI reporting period is associated with the SSB configuration indicated or activated by the first information.

[0094] Optionally, the first period can be any one of the following: an SSB period corresponding to the SSB configuration indicated or activated by the first information, and a maximum value between the SSB period corresponding to the SSB configuration indicated or activated by the first information and a periodic SSB period. For a periodic SSB, it can be understood as an SSB that is periodic, regular, and does not need to be dynamically indicated to be activated / deactivated.

[0095] (II) The first evaluation period and / or the first measurement period is equal to Max (the third parameter, the fourth parameter * the first period, the fifth parameter * the second period).

[0096] When the first evaluation period and / or the first measurement period is defined according to (II), the first power saving mechanism of the terminal system can be in an on / activated state. For example, the first power saving mechanism can be a C-DRX mechanism or a cell DTX mechanism.

[0097] Optionally, the first period can be any one of: a SSB period corresponding to the SSB configuration indicated or activated by the first information, a maximum of the SSB period corresponding to the SSB configuration indicated or activated by the first information and a periodic SSB period. For a periodic SSB, it can be understood as a SSB that is periodic, regular, and does not need to be dynamically indicated to be activated / deactivated.

[0098] Optionally, the second period is a configuration period of the first power saving mechanism. For example, the second period is less than or equal to a first threshold value; the first threshold value can be a predefined value or a value configured by a network side device.

[0099] Optionally, any one of the third parameter, the fourth parameter and the fifth parameter can be a predefined value or a value configured by a network side device.

[0100] In a possible implementation, the fourth parameter and / or the fifth parameter can be 1.

[0101] In a possible implementation, the fourth parameter and the fifth parameter are equal, that is, (II) described above 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)).

[0102] Optionally, any one of the third parameter, the fourth parameter and the fifth parameter can be determined according to at least one of: a first SSB measurement window, a first measurement interval, and a CSI reporting period; wherein at least one of the first SSB measurement window, the first measurement interval and the CSI reporting period is associated with the SSB configuration indicated or activated by the first information.

[0103] (III) the first evaluation period and / or the first measurement period is equal to the sixth parameter * the second period.

[0104] When the first evaluation period and / or the first measurement period is defined according to (III), the first power saving mechanism of the terminal system can be in an on / activated state. For example, the first power saving mechanism can be a C-DRX mechanism or a cell DTX mechanism.

[0105] Optionally, the second period is a configuration period of the first power saving mechanism. For example, the second period is greater than or equal to a first threshold value; the first threshold value can be a predefined value or a value configured by a network side device.

[0106] Optionally, the sixth parameter can be a predefined value or a value configured by the network side device.

[0107] In a possible implementation, the sixth parameter can be 1, i.e., the first evaluation period and / or the first measurement period is equal to the second period.

[0108] Optionally, the sixth parameter can be determined according to at least one of the following: the first SSB measurement window, the first measurement interval, and the CSI reporting period; wherein at least one of the first SSB measurement window, the first measurement interval, and the CSI reporting period is associated with the SSB configuration indicated or activated by the first information.

[0109] The present disclosure will be described below in conjunction with specific embodiments.

[0110] Embodiment One

[0111] In this embodiment one, the network side configures SCell1 to contain one set of SSB configuration through high-layer RRC signaling, and the corresponding content is: SSB configuration number 1, SSB period = 20 ms, and SSB validity time interval = 10 ms. This SSB configuration can be understood as an on demand SSB configuration.

[0112] As shown in FIG. 2, initially, SCell1 has no SSB transmission, and SCell1 is in an inactive state for UE1. When the base station detects that UE1 has a large amount of downlink data to arrive, the base station activates SCell1 for UE1 at time slot n1, and indicates / activates the SSB configuration corresponding to SSB configuration number 1 on SCell1 to perform corresponding SSB transmission. At time slot n2, assuming that the base station detects that UE1 has no downlink data for a period of time, the base station indicates to deactivate the SSB configuration corresponding to SSB configuration number 1. When new downlink data arrives at time slot n3, the base station indicates / activates the SSB configuration corresponding to SSB configuration number 1 again.

[0113] In addition, the base station can configure periodic CSI reporting based on SSB for UE1 at time slot n1+3, and the reporting period is 20 ms. Therefore, the reporting at time slot n2-10 can be normally reported, and the reporting at time slot n2+10 can also be normally reported when an SSB transmission occasion is received before the CSI reference resource; however, the reporting at time slot n2+30 is discarded when no SSB transmission occasion is received before the CSI reference resource.

[0114] Embodiment Two

[0115] In the second embodiment, the network side configures SCell1 to contain two sets of SSB configurations through high-layer RRC signaling. The corresponding contents are as follows: 1) SSB configuration number 1, SSB period = 20 ms, SSB validity time interval = 10 ms; and 2) SSB configuration number 2, SSB period = 40 ms, SSB validity time interval = 10 ms. The SSB configuration can be understood as an on demand SSB configuration.

[0116] As shown in FIG. 3, the default SSB configuration 2 is valid when SCell1 is deactivated. When the base station detects that UE1 has a large amount of downlink data to arrive, the base station activates SCell1 for UE1 at time slot n1, and indicates / activates the SSB configuration corresponding to SSB configuration number 1 on SCell1 to perform corresponding SSB transmission. At time slot n2, the base station detects that UE1 has no downlink data for a period of time, and indicates to activate the SSB configuration corresponding to SSB configuration number 2, that is, to switch the SSB period to a large period. When new downlink data arrives at time slot n3, the SSB configuration corresponding to SSB configuration number 1 is indicated / activated again, that is, the SSB period is switched to a small period.

[0117] In addition, the base station can configure the SSB-based periodic CSI reporting for UE1 at time slot n1+3, and there are two reporting periods. The reporting period 20 ms is associated with SSB configuration number 1, and the reporting period 40 ms is associated with SSB configuration number 2. The terminal uses the reporting period 20 ms for reporting between time slots n1+3 and n2, uses the reporting period 40 ms for reporting between time slots n2+3 and n3, and uses the reporting period 20 ms for reporting after time slot n3+3.

[0118] FIG. 4 is a flowchart of a communication method provided by an embodiment of the present disclosure, which is applied to a network side device. As shown in FIG. 4, the method includes the following steps:

[0119] Step 41: The network side device sends first information to a terminal. The first information is used to indicate or activate an SSB configuration.

[0120] In the embodiment of the present disclosure, the first information can be, but is not limited to, RRC signaling, MAC CE, or DCI, etc.

[0121] In an optional implementation, the first information is used to indicate or activate one set of SSB configurations.

[0122] Optionally, the first information can include at least one of the following:

[0123] The sequence number of the SSB configuration, that is, the sequence number of the indicated or activated SSB configuration;

[0124] an identity ID of a secondary cell (SCell), the secondary cell being, for example, a secondary cell on which an on demand SSB is transmitted, i.e., the SSB is transmitted on the secondary cell based on an indicated or activated SSB configuration;

[0125] an SSB periodicity, i.e., an SSB periodicity corresponding to the SSB configuration indicated or activated by the first information, which can be understood as an SSB transmission periodicity;

[0126] a first time interval, which is specifically an SSB validity time interval, used to determine an SSB transmission validity time, etc.

[0127] By the scheme of the embodiments of the present disclosure, the terminal can select a suitable SSB configuration, thereby meeting the demand of measurement reporting.

[0128] Optionally, before the first information is sent to the terminal, the communication method in the embodiments of the present disclosure can further include:

[0129] The network side device sends configuration information to the terminal, the configuration information including at least one set of SSB configuration, and the first information being used to indicate or activate one set of SSB configuration from the at least one set of SSB configuration. The at least one set of SSB configuration is at least one set of on demand SSB configuration, i.e., aperiodic SSB configuration.

[0130] For example, the network side device can send the configuration information through high layer RRC signaling. In addition to the at least one set of on demand SSB configuration, the configuration information can further include a periodically occurring SSB configuration.

[0131] Optionally, the SSB configuration can include at least one of the following:

[0132] a serial number of the SSB configuration, based on which the corresponding SSB configuration can be indicated;

[0133] an SSB periodicity, i.e., an SSB periodicity corresponding to the SSB configuration;

[0134] an SSB transmission duration;

[0135] a second time interval, which is specifically an SSB validity time interval, used to determine an SSB transmission validity time, etc.

[0136] an SSB transmission power, used to indicate the power when the SSB is transmitted.

[0137] Optionally, the communication method in the embodiments of the present disclosure can further include:

[0138] The network-side device sends a CSI reporting configuration to the terminal; the CSI reporting configuration comprises at least one reporting period, and the at least one reporting period meets that different reporting periods are associated with different SSB configurations. The different reporting periods associated with different SSB configurations can be understood as different reporting periods being associated with different SSB periods. In this way, after the SSB configuration is indicated or activated, the CSI reporting can be performed by using the reporting period associated with the SSB period contained in the SSB configuration, so that the CSI reporting period and the SSB transmission period are adapted, and the CSI cannot be reported in time or the reporting resource is wasted is avoided.

[0139] Optionally, the CSI reporting configuration is associated with a first resource set, and a SSB transmission occasion corresponding to the first resource set is same as a SSB transmission occasion corresponding to the SSB configuration indicated or activated by the first information. In this way, the CSI reporting period and the SSB transmission period are adapted, and the CSI cannot be reported in time or the reporting resource is wasted is avoided.

[0140] Optionally, the first resource set can comprise one or more SSB indexes, so as to perform the CSI reporting by using the SSB corresponding to the SSB index.

[0141] It should be noted that the communication method provided by the embodiments of the present disclosure can be executed by a communication device or a control module in the communication device for executing the communication method.
