MIMO transmission can be Single-User MIMO (SU-MIMO) or Multiple-User MIMO (MU-MIMO). Depending on the configuration and number of antenna combinations, MIMO transmission can be 2D-MIMO, 3D-MIMO, Full-Dimension MIMO (FD-MIMO), or Massive-MIMO. It can also be diversity transmission, pre-coded transmission, or beamforming transmission, etc.

[0156] The following section will first introduce application scenario examples of the embodiments of this application.

[0157] In existing Radio Resource Management (RRM) measurements based on Synchronization Signal Blocks (SSBs), the serving cell transmits at most one set of SSBs. The terminal performs measurements based on the SSB period configured by the network, the SSB Measurement Timing Configuration (SMTC) period, or special measurement periods (such as measCycleSCell). Therefore, the terminal has relatively deterministic measurement behavior, and the network can balance the terminal's measurement power consumption and measurement result quality by controlling parameters such as the SSB period, SMTC period, and special measurement period.

[0158] However, the serving cell may stop sending SSBs to conserve energy, or it may use SSBs with longer cycles, resulting in the terminal being unable to receive SSBs for measurement or experiencing long measurement delays. To address this issue, the serving cell can send SSBs with shorter cycles on demand. Once the terminal completes its measurement task or SSB-based operation, the serving cell stops sending on-demand SSBs and returns to a power-saving state.

[0159] Based on the above application scenarios, some serving cells may send multiple sets of SSBs within a period of time, that is, on-demand SSBs and the original long-cycle SSBs coexist. When the network sends multiple sets of SSBs, the existing terminal measurement rules cannot reflect the advantages of on-demand SSBs. If the terminal determines its measurement behavior on its own, the terminal may experience problems such as excessive power consumption or excessive measurement latency due to frequent SSB measurements.

[0160] Based on the above, this application provides a method, apparatus, terminal, and network device for determining the SSB to be measured, in order to solve the problem that when the network sends multiple sets of SSBs, the terminal may experience excessive power consumption or excessive measurement delay due to frequent SSB measurements.

[0161] See Figure 1 This application provides a method for determining the SSB to be measured, applied to a terminal, specifically including the following steps:

[0162] Step 101: Receive the first signaling sent by the network device, and determine at least one group of SSBs to be measured from the first SSB set according to the group identifier of at least one group of SSBs carried in the first signaling; wherein, the first SSB set includes multiple groups of SSBs in the transmitting state in the first serving cell;

[0163] Alternatively, based on the configuration information, at least one set of SSBs to be measured is determined from the first set of SSBs; wherein the first set of SSBs includes multiple sets of SSBs in the transmitting state in the first serving cell, and the configuration information includes SSB configuration information, or the configuration information includes measurement configuration information and SSB configuration information.

[0164] In the above embodiments, when multiple groups of SSBs are in the transmitting state in the first serving cell, in one approach, the terminal can determine the at least one group of SSBs to be measured from the multiple groups of SSBs in the transmitting state based on the group identifier of at least one group of SSBs carried in the first signaling; in another approach, the terminal can determine the at least one group of SSBs to be measured from the multiple groups of SSBs in the transmitting state based on configuration information. Thus, the terminal does not need to measure all SSBs in the transmitting state, avoiding problems such as excessive power consumption or excessive measurement latency caused by frequent SSB measurements.

[0165] It should be noted that multiple SSBs in the sending state can also be referred to as multiple SSBs in the active state.

[0166] For example, the multiple sets of SSBs in the transmission state may include: cell-level SSBs that are periodically transmitted in the first serving cell and at least one set of on-demand SSBs. For instance, the first SSB set includes a first set of SSBs and a second set of SSBs. The second set of SSBs is an on-demand SSB configured by the network for the terminal. The second set of SSBs requires the network device to send an activation signaling to the terminal before the network transmits it. The first set of SSBs is configured at the cell level, and the network decides whether to transmit it. When the first set of SSBs is active, the network will periodically transmit the first set of SSBs.

[0167] It should be noted that in the scheme of determining at least one group of SSBs to be measured from the first SSB set based on the configuration information, the configuration information of each group of SSBs can be the content explicitly indicated by the signaling, or the content calculated or inferred by the terminal based on existing information.

[0168] Optionally, the first signaling includes: secondary cell activation signaling, and / or, measurement configuration signaling.

[0169] The two schemes included in the above embodiments are described below.

[0170] Option 1: Receive the first signaling sent by the network device; determine the at least one group of SSBs to be measured from the first SSB set based on the group identifier of at least one group of SSBs carried in the first signaling.

[0189] The first formula is: SFN SSB_k =SFN SSB_0 ±k*T SSB / (10*F),k={1,2,…,F-1},T SSB SFN is the largest SSB period in group F. SSB_0 SFN is the SFN occupied by the arbitrarily selected group of SSBs with the longest period. SSB_k F represents the SFN occupied by the k-th SSB, where F is a T SSB The number of SSB burst sets sent in the middle.

[0190] Item 3: If, based on the SSB configuration information, it is determined that each group of SSBs in the second SSB set has a not completely identical center frequency, select T groups of SSBs from the second SSB set. The center frequency of the T groups of SSBs is the same as the center frequency indicated in the measurement configuration information, 1 ≤ T < C, where C is the number of SSB groups in the second SSB set, and T and C are positive integers; determine at least one group of SSBs to be measured from the T groups of SSBs.

[0191] In some implementations, determining at least one group of SSBs to be measured from the T groups of SSBs includes one of the following:

[0196] If the half-frame indication and / or the SSB index in the candidate set are not the same, at least one set of SSBs to be measured is determined from the candidate set in accordance with the second rule.

[0197] The first rule includes any one of the following:

[0198] If the system frame number (SFN) occupied by each group of SSBs in the candidate set satisfies the first formula, the candidate set is determined as the SSB to be measured;

[0199] If the system frame number SFN occupied by each group of SSBs in the candidate set does not satisfy the first formula, and the SSB period of each group of SSBs in the candidate set is the same, the group of SSBs corresponding to the first SSB received in the time domain is determined as the SSB to be measured.

[0200] If the system frame number SFN occupied by each group of SSBs in the candidate set does not satisfy the first formula, and the SSB period of each group of SSBs in the candidate set is different, the group of SSBs with the shortest period in the candidate set shall be determined as the SSB to be measured.

[0201] The first formula is: SFN SSB_k =SFN SSB_0 ±k*T SSB / (10*F),k={1,2,…,F-1},T SSB SFN is the largest SSB period in group F. SSB_0 SFN is the SFN occupied by the arbitrarily selected group of SSBs with the longest period. SSB_k F represents the SFN occupied by the k-th SSB, where F is a T SSB The number of SSB burst sets sent in the middle.

[0202] The second rule includes any one of the following:

[0203] If only the first group of SSBs in the candidate set includes the SSB index set indicated in the measurement configuration information, then the first group of SSBs is determined as the group of SSBs to be measured; wherein, the first group of SSBs is any group of SSBs in the candidate set, and the SSB index set includes at least one SSB index; or,

[0204] If the minimum set of multiple SSBs in the candidate set covers the SSB index set indicated in the measurement configuration information, the minimum set is determined as the SSB to be measured; or,

[0205] If multiple SSBs in the candidate set can cover the SSB index set indicated in the measurement configuration information, the SSB with the shortest SSB period among the multiple SSBs is determined as the SSB to be measured.

[0206] Item 4: If, based on the SSB configuration information, it is determined that each group of SSBs in the first SSB set has a not completely identical center frequency, and the center frequency is not included in the measurement configuration information, the first SSB set is taken as a candidate set; according to the second rule, at least one group of SSBs to be measured is determined from the candidate set.

[0207] The second rule includes any one of the following:

[0210] If multiple SSBs in the candidate set can cover the SSB index set indicated in the measurement configuration information, the SSB with the shortest SSB period among the multiple SSBs is determined as the SSB to be measured.

[0211] It should be noted that the example of determining at least one set of SSBs to be measured from the second SSB set based on the configuration information is similar to the principle of determining at least one set of SSBs to be measured from the first SSB set based on the configuration information in Scheme 2. For details, please refer to the example in Scheme 2.

[0212] Option 2: Based on the configuration information, determine at least one group of SSBs to be measured from the first SSB set; wherein, the measurement configuration information includes at least one of the following parameter types: SSB group identifier, SSB center frequency, SSB index; the SSB configuration information includes at least one of the following parameter types: SSB group identifier, SSB center frequency, SSB index, SSB half-frame indicator.

[0213] In some embodiments, determining at least one set of SSBs to be measured from the first SSB set based on the configuration information includes any one of the following items 1 to 4:

[0214] Item 1: If, based on the SSB configuration information, it is determined that each group of SSBs in the first SSB set has the same center frequency, half-frame indication, and SSB index, the first SSB set is used as a candidate set; according to the first rule, at least one group of SSBs to be measured is determined from the candidate set.

[0215] The first rule includes any one of the following:

[0216] Rule 1-1: If the system frame number (SFN) occupied by each group of SSBs in the candidate set satisfies the first formula, the candidate set shall be determined as the SSB to be measured.

[0217] Rule 1-2: If the system frame number SFN occupied by each group of SSBs in the candidate set does not satisfy the first formula, and the SSB period of each group of SSBs in the candidate set is the same, the group of SSBs corresponding to the first SSB received in the time domain shall be determined as the SSB to be measured.

[0218] Rule 1-3: If the system frame number SFN occupied by each group of SSBs in the candidate set does not satisfy the first formula, and the SSB period of each group of SSBs in the candidate set is different, the group of SSBs with the shortest period in the candidate set shall be determined as the SSB to be measured.

[0219] The first formula is: SFN SSB_k =SFN SSB_0 ±k*T SSB / (10*F),k={1,2,…,F-1},T SSB SFN is the largest SSB period in group F. SSB_0 SFN is the SFN occupied by the arbitrarily selected group of SSBs with the longest period. SSB_k F represents the SFN occupied by the k-th SSB, where F is a T SSB The number of SSB burst sets sent in the middle.

[0220] Regarding item 1, the following will be combined with... Figures 6 to 7 The first rule will be introduced.

[0221] Example 1

[0222] Assume the terminal acquires two active SSBs in the first serving cell. Both SSBs use an 8-bit bitmap to represent their transmission mode. The main information of the two SSBs is shown in Table 1 below:

[0223] parameter Configuration of the first group of SSBs Configuration of the second group of SSBs Group number 0 1 Center frequency ARFCN-ValueNR1 ARFCN-ValueNR1 Period (ms) 20 20 ssb-positionsInBurst {0,0,1,1,1,1,0,0} {0,0,1,1,1,1,0,0} Half-frame indicator 0 0

[0224] Table 1

[0225] In Table 1 above, ARFCN-ValueNR represents the center frequency of a group of SSBs; a half-frame indicator of 0 indicates that the group of SSBs is transmitted in the first half of each radio frame, and a half-frame indicator of 1 indicates that the group of SSBs is transmitted in the second half of each radio frame. All other main parameters of the two groups of SSBs are the same, including subcarrier spacing and transmit power.

[0226] It should be noted that the second set of SSBs is an on-demand SSB configured by the network for the terminal. This second set of SSBs requires the network device to send an activation signaling to the terminal before the network sends it. The first set of SSBs is configured at the cell level, and the network decides whether to send it. When the first set of SSBs is active, the network will periodically send it. The configuration information corresponding to the first set of SSBs can be content explicitly indicated by the signaling or content calculated or inferred by the terminal based on existing information.

[0227] In this example, assuming the first group of SSBs is in the transmitting state, since both groups of SSBs have the same center frequency and half-frame indication, and the parameter `ssb-positionsInBurst` indicates that both groups of SSBs have identical SSB indices, when the network device needs to activate the second group of SSBs, the network device needs to ensure that the two groups of SSB instances do not occupy the same OFDM symbol through a reasonable time-domain offset indication. This is based on the period T of the first group of SSBs. SSB1 The second group of SSBs can be calculated in a T. SSB1 The number of SFNs that can be used in the middle is Y = (T SSB1 / 10)-1=1.

[0228] The temporal distributions of the two SSB burst sets are as follows: Figure 6 As shown, Figure 6 Each SSB burst set represents its location within a radio half-frame, not its time-domain length. In this case, the terminal should receive and measure both SSB instances indiscriminately, effectively treating the two SSBs as a single SSB with a period of 10 milliseconds for rapid measurement.

[0229] Similarly, suppose the terminal learns that there are four groups of SSBs in the transmitting state in the first serving cell. The main information of the four groups of SSBs is shown in Table 2 below:

[0230]

[0231] Table 2

[0232] According to the period T of the first group of SSBs SSB1 It is possible to calculate the other three groups of SSB in a T SSB1 The number of SFNs that can be used in the middle is Y = (T SSB1 / 10)-1=3. At this time, the temporal distribution of the four SSB burst sets is as follows: Figure 7 As shown. At this point, the terminal should receive and measure the four SSB instances indiscriminately, that is, treat the four SSBs as a single SSB with a period of 10 milliseconds and perform a fast measurement.

[0233] Similarly, based on Table 2 above, when only one of the other three SSB groups is active, except for the first group of SSBs, the SFN where that group of SSBs is configured will be active. SSBx When the following relationship is satisfied: SFN SSB1 =SFN SSBx ±T SSB / 20, where SFN SSB1 The SFN occupied by the first SSB (i.e., SSB1) SSBx For the SFN occupied by the active SSB among the remaining three SSB groups, T SSB The longest SSB period among the two SSB groups is T, which is equal to the periods of SSB1 and SSBx. SSB =40ms. The terminal can also receive and measure the two sets of SSB instances without difference, that is, the two sets of SSB are equivalent to one set with a period of T. SSB1 SSB performs fast measurements in 2 milliseconds.

[0234] It should be pointed out that, such as Figure 8 As shown, when multiple SSBs in the transmission state differ only in their periods, it may be equivalent to performing measurements with a shorter SSB period.

[0235] However, assuming Figure 8 If the period of the first group of SSBs becomes 80ms, then the three groups of SSBs do not satisfy the first formula. Since the period of the second group of SSBs is the shortest, the second group of SSBs is determined as the group of SSBs to be measured.

[0236] It should be noted that, in addition to determining the SSB to be measured based on the above examples, the terminal can also simultaneously measure SSB instances belonging to other effective SSB configurations, thereby improving the accuracy of measurement results and shortening measurement latency.

[0237] Based on Example 1 above, when the system frame number SFN occupied by each group of SSBs in the candidate set satisfies the first formula, the terminal can consider multiple groups of SSBs in the transmitting state as equivalent to a group of SSBs with a shorter period, and the terminal should receive all effective groups of SSBs without distinction. When the system frame number SFN occupied by each group of SSBs in the candidate set does not satisfy the first formula, if the SSB periods of each group of SSBs are the same, the terminal measures the first SSB received in the time domain and measures it according to its period. When the system frame number SFN occupied by each group of SSBs in the candidate set does not satisfy the first formula, if the SSB periods of each group of SSBs are not the same, the terminal measures the group of SSBs with the shortest SSB period in the candidate set.

[0238] Example 2

[0239] The terminal learns that there are two sets of SSB configurations in a cell, both of which are active. Both sets of SSBs use an 8-bit bitmap to represent the transmission mode of the SSB. It is assumed that in a measurement instruction, the measurement configuration information sent by the network instructs the terminal to perform the measurement based on {SSB3 SSB4}.

[0240] In one implementation, assume that the main information of the two sets of SSBs in the transmission state is shown in Table 3 below, wherein the period configurations of the two sets of SSBs are different:

[0241]

[0242]

[0243] Table 3

[0244] In Table 3 above, the SSB index in ssb-positionsInBurst starts from 0, and SSB3 represents the 4th SSB in ssb-positionsInBurst.

[0245] At this point, the distribution of the two SSB burst sets in the time domain is as follows: Figure 9 As shown, since the two sets of SSBs are identical in configuration except for their periods, but do not satisfy the first formula (meaning the terminal cannot convert the two sets of SSBs into a single SSB with a shorter period), the terminal should select the SSB with the shorter period for measurement to reduce measurement complexity. Figure 9 The time-domain distribution diagram shown indicates that the terminal measures the second group of SSBs.

[0246] In another implementation, it is assumed that the terminal is aware of the main information of the two active SSBs as shown in Table 4 below, wherein the two SSBs occupy different radio frames:

[0247] parameter Configuration of the first group of SSBs Configuration of the second group of SSBs Group number 0 1 Center frequency ARFCN-ValueNR1 ARFCN-ValueNR1 Period (ms) 40 40 ssb-positionsInBurst {0,0,1,1,1,1,0,0} {0,0,1,1,1,1,0,0} Half-frame indicator 0 0

[0248] Table 4

[0249] At this point, the distribution of the two SSB burst sets in the time domain is as follows: Figure 10 As shown. At this time, the two SSBs are identical in configuration except for the radio frames they occupy. However, the two SSBs do not satisfy the first formula, meaning the terminal cannot equate the two SSBs to a single SSB with a shorter period, and since the periods of the two SSBs are the same. Therefore, the terminal can select the configuration corresponding to the first SSB received in the time domain for measurement. In this embodiment, it is assumed that the first SSB instance received by the terminal is the SSB instance where SFN 0 is located, so the terminal should complete the measurement based on the SSB configuration. In addition, since the center frequencies of the two SSBs are the same, the terminal can also simultaneously measure SSB instances belonging to other configurations to improve the accuracy of the measurement results or shorten the measurement latency.

[0250] Item 2: If, based on the SSB configuration information, it is determined that each group of SSBs in the first SSB set has the same center frequency, different half-frame indications, and / or SSB indices, the first SSB set is taken as a candidate set; according to the second rule, at least one group of SSBs to be measured is determined from the candidate set.

[0251] The second rule includes any one of the following:

[0252] Rule 2-1: If only the first group of SSBs in the candidate set includes the SSB index set indicated in the measurement configuration information, the first group of SSBs shall be determined as a group of SSBs to be measured; wherein, the first group of SSBs is any group of SSBs in the candidate set, and the SSB index set includes at least one SSB index.

[0253] For example, such as Figure 2 In the first SSB set, there are two groups of SSBs: the first group of SSBs = {SSB0 SSB2 SSB4 SSB5 SSB6} and the second group of SSBs = {SSB1 SSB3 SSB5 SSB7}. The SSB index set indicated in the measurement configuration information is {SSB2 SSB4 SSB5}. The group of SSBs to be measured is the first group of SSBs = {SSB0 SSB2 SSB4 SSB5 SSB6}.

[0254] For example, such as Figure 3In the first SSB set, there are two groups of SSBs: the first group of SSBs = {SSB0 SSB2 SSB4 SSB5 SSB6} and the second group of SSBs = {SSB1 SSB3 SSB5 SSB7}. The SSB index set indicated in the measurement configuration information is {SSB1 SSB3 SSB5 SSB7}. The group of SSBs to be measured is the second group of SSBs = {SSB1 SSB3 SSB5 SSB7}.

[0255] Rule 2-2: If the smallest set of multiple SSBs in the candidate set covers the SSB index set indicated in the measurement configuration information, the smallest set shall be determined as the SSB to be measured.

[0256] For example, such as Figure 4 In the first SSB set, there are two groups of SSBs: the first group of SSBs = {SSB0 SSB2 SSB4 SSB5 SSB6} and the second group of SSBs = {SSB1 SSB3 SSB5 SSB7}. The SSB index set indicated in the measurement configuration information is {SSB2 SSB3 SSB4 SSB5}. The SSBs to be measured are the first group of SSBs = {SSB0 SSB2 SSB4 SSB5 SSB6} and the second group of SSBs = {SSB1 SSB3 SSB5 SSB7}.

[0257] Rule 2-3: If multiple SSBs in the candidate set can cover the SSB index set indicated in the measurement configuration information, the SSB with the shortest SSB period among the multiple SSBs shall be determined as the SSB to be measured.

[0258] The SSB period is the transmission period of the SSB.

[0259] For example, such as Figure 5 In the first SSB set, there are two groups of SSBs: the first group of SSBs = {SSB0 SSB2 SSB4 SSB5 SSB6} and the second group of SSBs = {SSB1 SSB3 SSB4 SSB5 SSB7}. Assuming that the SSB period of the second group of SSBs is shorter than that of the first group of SSBs, the SSB index set indicated in the measurement configuration information is {SSB4 SSB5}, and the group of SSBs to be measured is the second group of SSBs with the shortest period = {SSB1 SSB3 SSB4 SSB5 SSB7}.

[0260] The second item will be illustrated by Example 3 below.

[0261] Example 3

[0262] Suppose that the terminal learns that there are two sets of SSBs in the first serving cell, both of which are in the transmission state. Both sets of SSBs use an 8-bit bitmap to represent the transmission mode of the SSB. Also, assume that in a measurement instruction, the network instructs the terminal to perform a measurement based on {SSB3SSB4}.

[0263] In one implementation, it is assumed that the terminal is aware of the main information of the two active SSBs as follows:

[0264] As shown in Table 5, the configurations for the period and the wireless half-frame indicator differ:

[0265] parameter Configuration of the first group of SSBs Configuration of the second group of SSBs Group number 0 1 Center frequency ARFCN-ValueNR1 ARFCN-ValueNR1 Period (ms) 40 20 ssb-positionsInBurst {0,0,1,1,1,1,0,0} {0,0,1,1,1,1,0,0} Half-frame indicator 0 1

[0266] Table 5

[0267] At this point, the distribution of the two SSB burst sets in the time domain is as follows: Figure 11 As shown. According to ssb-positionsInBurst, the SSB indices of the two SSB groups are the same, both containing SSB 3 and SSB 4. Therefore, the terminal can perform this measurement based on the SSB with the shorter period, that is, the terminal measures the second SSB group.

[0268] In another implementation, it is assumed that the terminal is aware of the main information of the two sets of SSBs in the transmission state as shown in Table 6 below, wherein the configurations of period, ssb-positionsInBurst, and wireless half-frame indication are different:

[0269]

[0270]

[0271] Table 6

[0272] At this point, the distribution of the two SSB burst sets in the time domain and Figure 11 The two groups of SSBs are the same, but their airspace transmission modes differ, specifically the SSB-positionsInBurst. Based on the network device's measurement configuration information, the terminal determines that SSB 3 and SSB 4 need to be measured. Since the first group of SSBs only transmits SSB 4, while the second group transmits both SSB 3 and SSB 4, the terminal should select the second group of SSBs to complete the SSB measurement indicated by the measurement configuration information.

[0273] In another implementation, it is assumed that the terminal is aware of the main information of the two sets of SSBs in the transmission state as shown in Table 7 below, where the configurations of period, ssb-positionsInBurst, and wireless half-frame indication are different:

[0274] parameter Configuration of the first group of SSBs Configuration of the second group of SSBs Group number 0 1 Center frequency ARFCN-ValueNR1 ARFCN-ValueNR1 Period (ms) 40 20 ssb-positionsInBurst {1,0,1,0,1,0,1,0} {0,1,0,1,0,1,0,1} Half-frame indicator 0 1

[0275] Table 7

[0276] At this point, the distribution of the two SSB burst sets in the time domain and Figure 11 The two groups of SSBs are the same, but their airspace transmission modes differ, specifically the SSB-positionsInBurst. Based on the network device's measurement configuration information, the terminal determines that SSB 3 and SSB 4 need to be measured. Since both the first and second groups of SSBs only transmit SSB 4, the terminal should simultaneously select both groups to complete the SSB measurements indicated by the measurement configuration information.

[0277] Similarly, assuming the main information of the two known active SSBs of the aforementioned terminal is shown in Table 8 below, where the configurations of period, ssb-positionsInBurst, and wireless half-frame indication are different:

[0278] parameter Configuration of the first group of SSBs Configuration of the second group of SSBs Group number 0 1 Center frequency ARFCN-ValueNR1 ARFCN-ValueNR1 Period (ms) 40 20 ssb-positionsInBurst {0,1,1,0,0,1,1,0} {0,0,1,1,1,1,0,0} Half-frame indicator 0 1

[0279] Table 8

[0280] At this point, the distribution of the two SSB burst sets in the time domain and Figure 11 The two groups of SSBs are the same, but their airspace transmission modes differ, specifically the SSB-positionsInBurst. Based on the network device's measurement configuration information, the terminal determines that SSB 3 and SSB 4 need to be measured. Since the first group of SSBs does not transmit SSB 3 and SSB 4, but the second group transmits them, the terminal should select the second group of SSBs to complete the SSB measurement indicated by the measurement configuration information.

[0281] Item 3: If, based on the SSB configuration information, it is determined that each group of SSBs in the first SSB set has a not completely identical center frequency, select M groups of SSBs from the first SSB set. The center frequencies of the M groups of SSBs are the same as the center frequencies indicated in the measurement configuration information, 1 ≤ M < K, where K is the number of SSB groups in the first SSB set, and M and K are positive integers; determine at least one group of SSBs to be measured from the M groups of SSBs.

[0282] In some embodiments, determining at least one group of SSBs to be measured from the M groups of SSBs includes one of the following:

[0283] When M=1, a group of SSBs with the same center frequency as indicated in the measurement configuration information are identified as the SSBs to be measured;

[0284] In the case of 1 < M < K, M groups of SSBs are selected as a candidate set, and at least one group of SSBs to be measured is determined from the candidate set according to the half-frame indication and the SSB index.

[0285] The step of determining at least one set of SSBs to be measured from the candidate set based on the half-frame indication and the SSB index includes any one of the following:

[0286] If the half-frame indication and the SSB index are the same in the M groups of SSBs, at least one group of SSBs to be measured is determined from the candidate set according to the first rule;

[0287] If the half-frame indication and / or the SSB index in the candidate set are not the same, at least one set of SSBs to be measured is determined from the candidate set in accordance with the second rule.

[0288] The first rule includes any one of the following:

[0289] If the system frame number (SFN) occupied by each group of SSBs in the candidate set satisfies the first formula, the candidate set is determined as the SSB to be measured;

[0290] If the system frame number SFN occupied by each group of SSBs in the candidate set does not satisfy the first formula, and the SSB period of each group of SSBs in the candidate set is the same, the group of SSBs corresponding to the first SSB received in the time domain is determined as the SSB to be measured.

[0291] If the system frame number SFN occupied by each group of SSBs in the candidate set does not satisfy the first formula, and the SSB period of each group of SSBs in the candidate set is different, the group of SSBs with the shortest period in the candidate set shall be determined as the SSB to be measured.

[0292] The first formula is: SFN SSB_k =SFN SSB_0 ±k*T SSB / (10*F),k={1,2,…,F-1},T SSB SFN is the largest SSB period in group F. SSB_0 SFN is the SFN occupied by the arbitrarily selected group of SSBs with the longest period. SSB_k F represents the SFN occupied by the k-th SSB, where F is a T SSB The number of SSB burst sets sent in the middle.

[0293] The second rule includes any one of the following:

[0294] If only the first group of SSBs in the candidate set includes the SSB index set indicated in the measurement configuration information, then the first group of SSBs is determined as the group of SSBs to be measured; wherein, the first group of SSBs is any group of SSBs in the candidate set, and the SSB index set includes at least one SSB index; or,

[0295] If the minimum set of multiple SSBs in the candidate set covers the SSB index set indicated in the measurement configuration information, the minimum set is determined as the SSB to be measured; or,

[0296] If multiple SSBs in the candidate set can cover the SSB index set indicated in the measurement configuration information, the SSB with the shortest SSB period among the multiple SSBs is determined as the SSB to be measured.

[0297] Example 4

[0298] Suppose the terminal knows that there are two sets of SSBs in the first serving cell, both of which are in the transmitting state. Both sets of SSBs use an 8-bit bitmap to represent the transmission mode of the SSB. Assume that the main information of the two active SSBs known to the terminal is shown in Table 9 below:

[0299] parameter Configuration of the first group of SSBs Configuration of the second group of SSBs Group number 0 1 Center frequency ARFCN-ValueNR1 ARFCN-ValueNR2 Period (ms) 40 20 ssb-positionsInBurst {0,0,1,1,1,1,0,0} {0,0,1,1,1,1,0,0} Half-frame indicator 0 0

[0300] Table 9

[0301] Since the center frequencies of the two groups of SSBs are different, the terminal determines the SSB to be measured based on the center frequency indicated in the measurement configuration information. For example, when the measurement configuration information indicates that the terminal measures a group of SSBs with a center frequency of ARFCN-ValueNR1, the terminal measures the first group of SSBs; when the measurement configuration information indicates that the terminal measures a group of SSBs with a center frequency of ARFCN-ValueNR2, the terminal measures the second group of SSBs.

[0302] Item 4: If, based on the SSB configuration information, it is determined that each group of SSBs in the first SSB set has a not completely identical center frequency, and the center frequency is not included in the measurement configuration information, the first SSB set is taken as a candidate set; according to the second rule, at least one group of SSBs to be measured is determined from the candidate set.

[0303] The second rule includes any one of the following:

[0304] If only the first group of SSBs in the candidate set includes the SSB index set indicated in the measurement configuration information, the first group of SSBs is determined as the SSB to be measured; wherein the first group of SSBs is any group of SSBs in the candidate set, and the SSB index set includes at least one SSB index; or,

[0305] If the minimum set of multiple SSBs in the candidate set covers the SSB index set indicated in the measurement configuration information, the minimum set is determined as the SSB to be measured; or,

[0306] If multiple SSBs in the candidate set can cover the SSB index set indicated in the measurement configuration information, the SSB with the shortest SSB period among the multiple SSBs is determined as the SSB to be measured.

[0307] The embodiments shown in Scheme 1 and Scheme 2 above clarify the terminal measurement behavior under different SSB configurations. While ensuring the terminal power consumption level, the measurement latency can be shortened as much as possible, avoiding problems such as excessive power consumption or excessive measurement latency caused by frequent SSB measurements.

[0308] Furthermore, in related technologies, a time-domain fast measurement window is used to limit the terminal's measurement behavior inside and outside the window. To control the terminal's measurement power consumption, a time-domain fast measurement window can be introduced. Within the fast measurement window, the terminal needs to perform fast measurements to complete the measurement task or required operation (such as SCell activation). Outside the fast measurement window, the terminal can apply existing long-cycle / low-speed measurements to control terminal power consumption. In different application scenarios, the start and end points of the fast measurement window have their own characteristics. In network energy-saving projects, the start point of the fast measurement window is defined as the moment when the terminal receives the on-demand SSB activation signaling, but the end point of the fast measurement window needs to be further designed.

[0309] Regarding the stopping conditions for the fast measurement window, methods based on OD-SSB deactivation signaling or a limited number of OD-SSB measurement samples are not optimal solutions in major application scenarios (such as RRM measurement and SCell activation of the serving cell). For example, after SCell activation, on-demand SSBs continue to transmit, and the fast measurement window remains valid, but the terminal does not need to perform fast measurements, leading to excessive terminal power consumption. In the method based on a limited number of OD-SSB instances, the number of SSB measurement samples required for different terminal measurement tasks varies, and the terminal's capabilities also affect the number of SSB measurement samples. Therefore, defining only the number of measurement samples cannot meet the needs of completing fast measurement tasks in different scenarios. Defining different numbers of measurement samples for different scenarios leads to complex terminal implementation and prevents good reuse of existing measurement mechanisms.

[0310] Based on the above, this application also provides the following embodiments for limiting the stopping conditions of the fast measurement window, and applying the above-mentioned schemes one and two to determine the SSB to be measured within the fast measurement window, so as to reduce the frequent measurement behavior of the terminal and achieve the purpose of controlling the power consumption of the terminal.

[0311] In some embodiments, determining the at least one group of SSBs to be measured based on the group identifier of at least one group of SSBs carried in the first signaling includes:

[0312] Upon receiving the SSB activation signal, open the quick measurement window;

[0313] Based on the group identifier of at least one group of SSBs carried in the first signaling, at least one group of SSBs to be measured in the fast measurement window is determined from the first set of SSBs.

[0314] In this embodiment, for the application scenario of opening a fast measurement window, it is possible to determine at least one group of SSBs that should be measured in the fast measurement window from multiple groups of SSBs in the transmission state according to the group identifier of at least one group of SSBs carried in the first signaling, thereby achieving the purpose of saving terminal power consumption.

[0315] It should be noted that the measurement behavior of the terminal in the quick measurement window can be found in the description of the various embodiments in Scheme 1 above, and will not be repeated here to avoid repetition.

[0316] In some embodiments, determining at least one set of SSBs to be measured from a first SSB set based on configuration information includes:

[0317] Upon receiving the SSB activation signal, open the quick measurement window;

[0318] Based on the configuration information, at least one set of SSBs to be measured in the fast measurement window is determined from the first SSB set.

[0319] In this embodiment, for application scenarios where a fast measurement window is enabled, it is possible to determine, based on configuration information, at least one group of SSBs that should be measured within the fast measurement window from multiple groups of SSBs in the transmission state, thereby saving terminal power consumption.

[0320] It should be noted that the measurement behavior of the terminal in the quick measurement window can be found in the description of the various embodiments in Scheme 2 above, and will not be repeated here to avoid repetition.

[0321] In some embodiments, after opening the fast measurement window, the method further includes:

[0322] If the terminal receives a secondary cell activation signaling message, and it is determined that the stopping condition of the fast measurement window is not met, then the fast measurement window is stopped after the secondary cell activation is completed; or,

[0323] If the terminal does not receive a secondary cell activation signaling and determines that it is performing Radio Resource Management (RRM) measurements, and if it is determined that the stopping conditions of the fast measurement window are not met, then the fast measurement window is stopped after completing one valid RRM measurement and reporting.

[0324] If any item in the first set of conditions is not met, the stopping condition of the fast measurement window is determined to be unsatisfactory.

[0325] The first set of conditions includes at least one of the following:

[0326] Received on-demand synchronization signal block (OD-SSB) deactivation signaling;

[0327] Received secondary cell deactivation signaling;

[0328] The deactivation timer for the secondary cell corresponding to the fast measurement window has timed out.

[0329] The last OD-SSB instance has been received.

[0330] The following example illustrates how to use Scheme 1 or 2 above to determine at least one set of SSBs to be measured in a quick measurement window.

[0331] Example 5: Suppose a terminal learns that two SSBs are in the transmitting state (also known as active state) in a first serving cell. Both SSBs use an 8-bit bitmap to represent their transmission mode. Assume the main information of the two SSBs known to the terminal is shown in Table 10 below:

[0332]

[0333]

[0334] Table 10

[0335] The first set of SSBs is a cell-level configuration and is in a periodically transmitted active state. The second set of SSBs is an on-demand SSB configured by the network for the terminal. The second set of SSBs will only be sent by the network device after the network device sends an activation signaling to the terminal. That is, after completing the configuration of the second set of SSBs, the network device sends an activation signaling to the terminal to put the second set of SSBs into an active state.

[0336] At this point, the terminal opens a fast measurement window in the time domain associated with the first serving cell. Within this window, the terminal can perform SSB measurements based on either Scheme 1 or 2 described above, as well as various extended scenarios. When the fast measurement window ends, the network device may stop sending the second set of SSBs. Therefore, the terminal only needs to perform measurements and other operations based on the first set of SSBs.

[0337] In one example, the stopping condition for the fast measurement window can be determined based on the deactivation signaling of the second set of SSBs, the deactivation signaling of the first serving cell, or the expiration of the deactivation timer (e.g., sCellDeactivationTimer).

[0338] In another example, the network device can indicate the number of SSB instances to be sent for the second group of SSBs. Once the second group of SSBs has finished being sent, the network device will stop sending the second group of SSBs. The terminal can stop the fast measurement window after the last SSB instance of the second group of SSBs.

[0339] In another example, when the network device requires the terminal to perform SCell activation or measurement, the terminal can stop the fast measurement window after completing the SCell operation or reporting a measurement result.

[0340] For example, suppose the network device sends a second set of SSBs to the terminal and requests the terminal to activate SCell, then the terminal's measurement rows based on the fast measurement window are as follows: Figure 12 As shown. Figure 12 In the diagram, the SSB burst set enclosed in the dashed circle represents the SSB burst set that the terminal needs to measure both inside and outside the fast measurement window.

[0341] The above embodiments clarify the termination conditions of the time-domain fast measurement window, which can adapt to different application scenarios and maximize the transmission function of on-demand SSB, ensuring that the terminal can quickly complete various measurements and operations that need to be performed.

[0342] See Figure 13 This application provides a method for determining the SSB to be measured, applied to a network device, including the following steps:

[0343] Step 1301: Send a first signaling message to the terminal, the first signaling message carrying at least one group identifier of an SSB, the group identifier being used to determine the SSB to be measured from a first set of SSBs, the first set of SSBs including multiple groups of SSBs in the transmitting state in the first serving cell; or,

[0344] The terminal sends configuration information, which is used to determine the SSB to be measured from a first SSB set; wherein the first SSB set includes multiple groups of SSBs in the transmitting state in the first serving cell, and the configuration information includes SSB configuration information, or the configuration information includes measurement configuration information and SSB configuration information.

[0345] It should be noted that multiple SSBs in the transmission state can also be referred to as multiple SSBs in the active state. Specifically, multiple SSBs in the transmission state can include: cell-level SSBs periodically transmitted in the first serving cell and at least one set of on-demand transmitted SSBs.

[0346] For example, the first SSB set includes a first group of SSBs and a second group of SSBs. The second group of SSBs is an on-demand SSB configured by the network for the terminal. The second group of SSBs requires the network device to send an activation signaling to the terminal before the network sends it. The first group of SSBs is configured at the cell level, and the network decides whether to send it. When the first group of SSBs is active, the network will periodically send the first group of SSBs.

[0347] Accordingly, the terminal determines at least one group of SSBs to be measured from multiple groups of SSBs in the transmitting state based on the group identifier of at least one group of SSBs carried in the first signaling; or, the terminal determines at least one group of SSBs to be measured from multiple groups of SSBs in the transmitting state based on configuration information. In this way, it is not necessary to measure all SSBs in the transmitting state, thus avoiding problems such as excessive power consumption or excessive measurement delay caused by frequent SSB measurements.

[0348] In some embodiments, the first signaling includes: secondary cell activation signaling, and / or, measurement configuration signaling.

[0349] In some embodiments, sending configuration information to the terminal includes:

[0350] The measurement configuration information is sent to the terminal via measurement configuration signaling; and / or,

[0351] The SSB configuration information is sent to the terminal via SSB configuration signaling.

[0352] In some application examples, the network sends measurement configuration signaling to the terminal to indicate information such as the time and frequency domain of the measurement resources and the reporting method. After receiving the measurement configuration signaling, the terminal performs measurements according to the time and frequency domain information of the measurement resources and reports the measurement results according to the corresponding reporting method.

[0353] In some application examples, the network sends SSB configuration signaling to the terminal to indicate the time and frequency domain information of the on-demand SSB. After receiving the SSB configuration signaling, the terminal can obtain the time and frequency domain information of the on-demand SSB and perform measurements.

[0354] In some embodiments, the measurement configuration information includes at least one of the following parameter types: SSB group identifier, SSB center frequency, and SSB index.

[0355] In some embodiments, the SSB configuration information includes at least one of the following parameter types: SSB group identifier, SSB center frequency, SSB index, and SSB half-frame indicator.

[0356] It should be noted that the method for determining at least one set of SSBs to be measured from the first set of SSBs based on SSB configuration information, or based on measurement configuration information and SSB location information, can be found in the terminal-side embodiment, and will not be repeated here.

[0357] See Figure 14 This application provides a device 1400 for determining the SSB to be measured, applied to a terminal, including:

[0366] In some embodiments, the SSB configuration information includes at least one of the following parameter types: SSB group identifier, SSB center frequency, SSB index, and SSB half-frame indicator.

[0367] In some embodiments, the first processing module 1401 includes any one of the following:

[0368] The first determining submodule is configured to, when determining, based on the SSB configuration information, that each group of SSBs in the first SSB set has the same center frequency, half-frame indication, and SSB index, use the first SSB set as a candidate set; and determine, according to a first rule, at least one group of SSBs to be measured from the candidate set.

[0369] The second determining submodule is used to, when it is determined from the SSB configuration information that each group of SSBs in the first SSB set has the same center frequency, different half-frame indications and / or SSB indices, use the first SSB set as a candidate set; and determine at least one group of SSBs to be measured from the candidate set according to the second rule.

[0370] The third determining submodule is used to select M groups of SSBs from the first SSB set, where the center frequencies of the M groups of SSBs are not completely identical, based on the SSB configuration information. The center frequencies of the M groups of SSBs are the same as the center frequencies indicated in the measurement configuration information, 1 ≤ M < K, K is the number of SSB groups in the first SSB set, and M and K are positive integers. From the M groups of SSBs, at least one group of SSBs to be measured is determined.

[0371] The fourth determining submodule is used to, when it is determined from the SSB configuration information that each group of SSBs in the first SSB set has a not completely identical center frequency, and the center frequency is not included in the measurement configuration information, take the first SSB set as a candidate set; and determine at least one group of SSBs to be measured from the candidate set according to the second rule;

[0372] The first rule and the second rule are different.

[0373] In some embodiments, the third determining submodule includes one of the following:

[0374] The first determining unit is used to determine, when M=1, a group of SSBs that have the same center frequency as indicated in the measurement configuration information as the SSBs to be measured;

[0375] The second determining unit is configured to, when 1 < M < K, select M groups of SSBs as a candidate set, and determine at least one group of SSBs to be measured from the candidate set according to the half-frame indication and the SSB index.

[0376] In some embodiments, the second determining unit is specifically used for any of the following:

[0377] If the half-frame indication and the SSB index are the same in the M groups of SSBs, at least one group of SSBs to be measured is determined from the candidate set according to the first rule;

[0378] If the half-frame indication and / or the SSB index in the candidate set are not the same, at least one set of SSBs to be measured is determined from the candidate set in accordance with the second rule.

[0379] In some embodiments, the first rule includes any one of the following:

[0380] If the system frame number (SFN) occupied by each group of SSBs in the candidate set satisfies the first formula, the candidate set is determined as the SSB to be measured;

[0381] If the system frame number SFN occupied by each group of SSBs in the candidate set does not satisfy the first formula, and the SSB period of each group of SSBs in the candidate set is the same, the group of SSBs corresponding to the first SSB received in the time domain is determined as the SSB to be measured.

[0382] If the system frame number SFN occupied by each group of SSBs in the candidate set does not satisfy the first formula, and the SSB period of each group of SSBs in the candidate set is different, the group of SSBs with the shortest period in the candidate set shall be determined as the SSB to be measured.

[0383] The first formula is: SFN SSB_k =SFN SSB_0 ±k*T SSB / (10*F),k={1,2,…,F-1},T SSB SFN is the largest SSB period in group F. SSB_0SFN is the SFN occupied by the arbitrarily selected group of SSBs with the longest period. SSB_k F represents the SFN occupied by the k-th SSB, where F is a T SSB The number of SSB burst sets sent in the middle.

[0384] In some embodiments, the second rule includes any one of the following:

[0385] If only the first group of SSBs in the candidate set includes the SSB index set indicated in the measurement configuration information, then the first group of SSBs is determined as the group of SSBs to be measured; wherein, the first group of SSBs is any group of SSBs in the candidate set, and the SSB index set includes at least one SSB index; or,

[0386] If the minimum set of multiple SSBs in the candidate set covers the SSB index set indicated in the measurement configuration information, the minimum set is determined as the SSB to be measured; or,

[0387] If multiple SSBs in the candidate set can cover the SSB index set indicated in the measurement configuration information, the SSB with the shortest SSB period among the multiple SSBs is determined as the SSB to be measured.

[0388] In some embodiments, the first signaling includes: secondary cell activation signaling, and / or, measurement configuration signaling.
