[0002] In related technologies, the network side typically reduces power consumption by not sending synchronization signals in some cells and / or sending synchronization signals with longer periods. In this case, if the terminal needs to obtain the synchronization signal of a certain cell, it needs to send a wake-up signal to the corresponding cell to wake up the network side to send a synchronization signal with a regular period in that cell, so as to meet the terminal's random access requirements.

[0003] However, in practical applications, there is currently no effective solution for how the terminal should send a wake-up signal. Summary of the Invention

[0199] The present application will now be described in further detail with reference to the accompanying drawings and embodiments.

[0200] In current 5G New Radio (NR) systems, terminals (also known as terminal devices) primarily utilize synchronization signals to achieve one or more of the following functions (one or more can also be understood as at least one): synchronization with one or more of the time, frequency, and spatial domains; automatic gain control (AGC); beam selection, etc. Specifically, the synchronization signal can be a synchronization signal and a physical broadcast channel block (SSB).

[0201] In related technologies, the methods for terminals to obtain configuration information related to synchronization signals (such as SSB configuration information) typically include the following:

[0202] The first method involves the terminal determining the transmission configuration of the synchronization signal based on the synchronization signal period and the beam through which the synchronization signal is transmitted, as indicated by the network side. Based on this determined transmission configuration, the terminal can then acquire the synchronization signal. For example, when the synchronization signal includes an SSB (Service Sequence Serving Cell), the network side (e.g., base station equipment) can configure the SSB-related information for the terminal via Radio Resource Control (RRC) messages. Specifically, the RRC message can include an SSB periodicity serving cell field and an SSB position inburst field. The ssb-periodicity serving cell field indicates the transmission period of the SSB, which can be in milliseconds (ms). The ssb-position inburst field can indicate the beam through a bitmap. In this case, the terminal can use the ssb-periodicity serving cell field and the ssb-position inburst field to determine the complete SSB transmission configuration.

[0203] The second method involves the terminal determining the transmission frequency of the synchronization signal based on a synchronization grid scanning method. The terminal then determines the subcarrier spacing of the synchronization signal based on the operating band of the synchronization grid to which the transmission frequency of the synchronization signal belongs, and by combining preset information (specifically, a preset correspondence). The frequency domain position information of the synchronization grid can be predefined.

[0204] Based on the indication information, the terminal obtains the transmission frequency and subcarrier spacing of the synchronization signal. For example, when the synchronization signal includes an SSB, the network side can indicate the location of the absolute frequency point in the system information through an RRC message, so that the terminal can search for the SSB at the indicated absolute frequency point location. At the same time, the terminal can obtain the frequency and width information of the SSB. Specifically, the RRC message can include an SSB frequency field and an SSB subcarrier spacing field; where the ssbfrequency field is used to indicate the frequency point where the SSB is located, and the ssbsubcarrierspacing field is used to indicate the subcarrier spacing of the SSB.

[0205] The third method involves the terminal determining the specific time slot and / or Orthogonal Frequency Division Multiplexing (OFDM) symbol corresponding to the synchronization signal based on the preset synchronization signal transmission pattern corresponding to the operating (or inferred) spectrum range (e.g., FR1, FR2, etc.) and the half-frame bits in the Master Information Block (MIB). The half-frame bits indicate whether the half-frame transmitting the SSB is the upper or lower half-frame of a radio frame, and these half-frame bits are carried in the Physical Broadcast Channel (PBCH) payload. The preset transmission pattern indicates which OFDM symbols the SSB transmits on within the half-frame. The preset transmission patterns corresponding to different spectrum ranges (or frequency points) are related to the operating frequency band and subcarrier spacing corresponding to the spectrum range; the specific correlation can be predefined. For example, when the synchronization signal includes an SSB, the transmission pattern of the SSB in a half-frame length can be predefined. For instance, when the frequency is less than 3 GHz, a single SSB transmission opportunity (also known as an SSB burst) can contain a maximum of 4 SSBs, located on the 2nd, 8th, 16th, and 22nd OFDM symbols in the half-frame, respectively. Alternatively, when the frequency is greater than or equal to 3 GHz and less than 6 GHz, a single SSB transmission opportunity can contain a maximum of 8 SSBs, located on the 2nd, 8th, 16th, 22nd, 30th, 36th, 44th, and 50th OFDM symbols in the half-frame, respectively.

[0206] Fourth, during the initial cell selection process, the terminal assumes that the synchronization signal is transmitted according to a predetermined period (e.g., 20ms).

[0207] The fifth method involves the terminal selecting any synchronization signal whose channel quality is greater than or equal to the RSRP threshold based on the reference signal received power (RSRP) threshold pre-configured on the network side, and initiating random access on the random access channel (RACH) resource corresponding to the selected synchronization signal.

[0208] As can be seen from the above description, the terminal can obtain the configuration information of the synchronization signal according to actual needs, and receive the synchronization signal based on the configuration information.

[0209] In related technologies, the network side typically sends synchronization signals (such as SSB) frequently with a period of 20ms. Correspondingly, the network side also needs to send system information associated with the synchronization signals (such as System Information Block 1 (SIB1)) with a period of 20ms to ensure the initial access performance of the terminal. Therefore, network devices usually find it difficult to enter a deep sleep mode, resulting in high power consumption.

[0210] To reduce the energy consumption of network devices, related technologies have proposed a scheme in which the network side does not send some public signals by default, and when a terminal needs to obtain public signals, the network side is triggered to send the corresponding public signals on demand. This can ensure that network devices enter a relatively deep sleep mode, thereby reducing energy consumption.

[0211] Specifically, the network side's default mode of not transmitting certain public signals (which can also be understood as a community energy-saving mode) can include the following two:

[0212] The first method involves the network side not sending any synchronization signals by default. Specifically, for example... Figure 1 As shown, under default conditions (which can also be understood as preset conditions), the network device corresponding to a certain cell does not send synchronization signals (such as SSB) and / or system information. In this case, if the terminal needs to obtain the synchronization signal and / or system information corresponding to that cell, the terminal can send a wake-up signal to the network device corresponding to that cell based on pre-configured information and / or information obtained from network devices in other cells, so as to trigger the network device in that cell to send the corresponding synchronization signal and / or system information; wherein, the wake-up signal can also be understood as an uplink wake-up signal, and the uplink refers to the direction in which the terminal sends information to the network device;

[0213] The second method involves the network side defaulting to sending long-period synchronization signals, specifically, such as... Figure 2As shown, the network device corresponding to a certain cell sends synchronization signals at long intervals by default. Based on the long-period synchronization signal, the terminal sends a wake-up signal to the network device to trigger the network device in that cell to send a short-period (e.g., 20ms) synchronization signal.

[0214] In practical applications, cells that do not send any synchronization signals by default and / or send long-period synchronization signals by default can be considered energy-saving cells. However, when a terminal sends a wake-up signal to an energy-saving cell, the following problem exists:

[0215] 1) When the energy-saving cell does not send any synchronization signal by default, the terminal cannot know the spatial information of the energy-saving cell (such as beam direction). There is currently no effective solution for how the terminal can determine the spatial parameters for sending the wake-up signal.

[0216] 2) In the case that energy-saving communities default to sending long-period synchronization signals, the number of bits in the synchronization signal is limited, so the information that the synchronization signal can carry is limited. In this case, there is currently no effective solution on how the network side can use the long-period synchronization signal to instruct the terminal to send one or more of the time domain information, frequency domain information, spatial domain information, code domain information, etc. of the wake-up signal.

[0217] Based on this, in various embodiments of this application, when a cell does not send any synchronization signal by default, and the terminal needs to obtain the synchronization signal of that cell, the network devices of other cells (such as neighboring cells) related to that cell configure the association relationship between the synchronization signals of other cells and the synchronization signal of that cell to the terminal, so that the terminal can use the received synchronization signals of other cells and combine the association relationship to determine the method of sending a wake-up signal, thereby triggering the network side to send a synchronization signal that can meet the needs of the terminal; when the synchronization signal sent by default by a cell cannot meet the needs of the terminal (such as sending a long-period synchronization signal), the network side issues configuration information related to sending a wake-up signal to the terminal, so that the terminal can send a wake-up signal based on the configuration information, thereby triggering the network side to send a synchronization signal that can meet the needs of the terminal.

[0218] The following describes the solutions of the embodiments of this application according to the different energy-saving methods adopted in the community.

[0219] Firstly, in scenarios where energy conservation is achieved in a residential community by not sending synchronization signals, this application provides a communication method applied to a terminal, such as... Figure 3 As shown, the method includes:

[0220] Step 301: Receive first information, the first information being used to indicate that the second synchronization signal of the second cell is associated with one or more first synchronization signals of the first cell;

[0221] Step 302: Receive one or more first synchronization signals;

[0222] Step 303: Send a first uplink signal, which is used to request the second synchronization signal.

[0223] In practical applications, the terminal may be referred to as UE, user, etc., and this application embodiment does not limit this.

[0224] The first cell is different from the second cell, such as Figure 4 As shown, the first cell and the second cell can be co-located or non-co-located. The second cell includes cells that do not transmit synchronization signals by default; that is, the second cell reduces energy consumption by not transmitting synchronization signals. In this case, the second cell can also be understood as an energy-saving cell. This application does not limit the names of the first cell and the second cell in its embodiments.

[0225] In practical applications, when a terminal performs initial access operations, it typically needs to obtain the synchronization signal from a nearby cell (which can also be understood as a cell that can provide services to the terminal) to determine the cell's network performance. However, when the terminal is located near the second cell, and the second cell is an energy-saving cell, since the second cell does not send synchronization signals by default, the terminal cannot receive the synchronization signal from the second cell and therefore cannot determine the performance of accessing the second cell.

[0226] To address the aforementioned issues, a first cell associated with (e.g., adjacent to) the second cell can inform terminals within its service range that a second cell exists nearby in a power-saving state (i.e., it does not send synchronization signals by default). Thus, when a terminal needs to obtain a synchronization signal, it can send an uplink signal to the second cell to request the second cell to begin sending synchronization signals; this can also be understood as waking up the second cell. Here, the uplink signal can also be called a wake-up signal.

[0227] In practical applications, the network equipment of the first cell can send (specifically, broadcast) first information to inform terminals within the range of the first cell of the association relationship (or association configuration) between the synchronization signal of the first cell and the synchronization signal of the second cell. Specifically, the network equipment can be a base station, such as a gNB. This application embodiment does not limit the name of the network equipment, as long as it performs its function. The first information can also be understood as configuration information, and this application embodiment does not limit the name of the first information. The synchronization signal type of the first cell can specifically be one of SSB, PBCH, Primary Synchronization Signal (PSS), Secondary Synchronization Signal (SSS), Low-Power Synchronization Signal (LP-SS), or a newly defined synchronization signal type in 6G mobile communication technology. The synchronization signal type of the second cell can specifically be one of SSB, PBCH, PSS, SSS, LP-SS, or a newly defined synchronization signal type in 6G. Furthermore, the synchronization signal type of the first cell can be the same as or different from the synchronization signal type of the second cell; this application embodiment does not limit this.

[0228] For example, suppose the number of synchronization signals in the first cell is M, and the number of synchronization signals in the second cell is N, where M and N are integers greater than or equal to 1. In this case, the first information sent by the first cell can indicate one of the following:

[0229] The synchronization signals of each of the M first cells correspond to one or more (one or more can also be understood as at least one) synchronization signals of the second cells.

[0230] The synchronization signals of each of the N second cells correspond to one or more synchronization signals of the first cells.

[0231] At this time, the terminal can use the first information to determine which or which first cells' synchronization signals are associated with the synchronization signal of each second cell.

[0232] After receiving the first information, in step 302, the terminal can receive the synchronization signal sent by the first cell; then, based on the received synchronization signal of the first cell and the first information, the terminal determines the second synchronization signal of the second cell that needs to be woken up (i.e., the second cell needs to be requested to send) from one or more synchronization signals of the second cell.

[0233] In practical applications, the terminal determines the second synchronization signal based on the received synchronization signal of the first cell and the conditions corresponding to that synchronization signal. All synchronization signals of the first cell can correspond to the same conditions; alternatively, each synchronization signal of the first cell can correspond to its own specific conditions. These conditions are related to the channel quality of the synchronization signal. Specifically,

[0234] When all synchronization signals in the first cell correspond to the same condition, among the synchronization signals (i.e., first synchronization signals) of one or more first cells corresponding to the second synchronization signal determined by the terminal, one or more first synchronization signals satisfy the condition. That is, in one embodiment, among the one or more first synchronization signals associated with the second synchronization signal, one or more first synchronization signals satisfy the first condition.

[0235] Given that each synchronization signal in the first cell corresponds to its own conditions (i.e., the conditions corresponding to different synchronization signals in the first cell may be different), among the synchronization signals (i.e., first synchronization signals) of one or more first cells corresponding to the second synchronization signal determined by the terminal, one or more first synchronization signals can satisfy the corresponding conditions. In other words, in one embodiment, among the one or more first synchronization signals associated with the second synchronization signal, one or more first synchronization signals respectively satisfy the corresponding second conditions.

[0236] In practical applications, the first condition can be set according to actual needs. In one embodiment, the first condition may include one of the following:

[0237] If the channel quality is greater than (or can be understood as higher than) the first threshold, then the terminal can be considered to be in the beam direction corresponding to the first synchronization signal.

[0238] If the channel quality is less than (or can be understood as below) the second threshold, then it can be considered that the terminal is not in the beam direction corresponding to the first synchronization signal.

[0239] If the channel quality is greater than the third threshold and less than the fourth threshold, then the terminal can be considered to be within a certain distance range of the beam direction corresponding to the first synchronization signal.

[0240] The channel quality may be associated with one or more of the following (one or more may also be understood as at least one):

[0241] Reference Signal Receiving Power (RSRP);

[0242] Reference Signal Receiving Quality (RSRQ);

[0243] Received Signal Strength Indication (RSSI).

[0244] In practical applications, the first threshold, second threshold, third threshold, and fourth threshold can be predefined. That is, in one embodiment, one or more of the first threshold, second threshold, third threshold, and fourth threshold are predefined. Of course, the first threshold, second threshold, third threshold, and fourth threshold can also be configured by the network side. That is, in one embodiment, the method may further include: receiving second information, the second information being used to indicate one or more of the first threshold, second threshold, third threshold, and fourth threshold. Here, the second information can also be understood as threshold configuration information; the signaling for transmitting the second information can be the same as or different from the signaling for transmitting the first information; the first information and the second information can be transmitted simultaneously, or the second information can be transmitted separately.

[0245] In practical applications, the second condition can be set according to actual needs. In one embodiment, the second condition may include one of the following:

[0246] The channel quality is greater than the corresponding fifth threshold;

[0247] The channel quality is less than the corresponding sixth threshold;

[0248] The channel quality is greater than the corresponding seventh threshold and less than the corresponding eighth threshold.

[0249] In practical applications, the fifth, sixth, seventh, and eighth thresholds can be predefined. That is, in one embodiment, one or more of the fifth, sixth, seventh, and eighth thresholds are predefined. Alternatively, the network side can configure the fifth, sixth, seventh, and eighth thresholds. In another embodiment, the method may further include receiving third information, which indicates one or more of the fifth, sixth, seventh, and eighth thresholds. Here, the third information can also be understood as threshold configuration information. The signaling transmitting the third information can be the same as or different from the signaling transmitting the first information. The first information and the third information can be transmitted simultaneously, or the third information can be transmitted separately.

[0250] When the second cell corresponds to multiple synchronization signals, all synchronization signals of the second cell can be considered as a set, namely the first synchronization signal set. In practical applications, the terminal can request the second cell to send all synchronization signals in the first synchronization signal set to obtain multiple synchronization signals and ensure the performance of accessing the second cell. In this case, the first synchronization signal set only contains the second synchronization signal.

[0251] Of course, the terminal may also request the second cell to send one or more synchronization signals from the first synchronization signal set that meet the terminal's requirements. In this way, the network side does not need to send all the synchronization signals of the second cell, which can effectively save energy. In this case, the first synchronization signal set includes the second synchronization signal and one or more third synchronization signals from the second cell (i.e., synchronization signals in the second cell that are not requested to be sent).

[0252] In practical applications, the terminal can determine one or more synchronization signals from the first set of synchronization signals that meet its requirements as the second synchronization signal to ensure network energy saving. In one embodiment, the second synchronization signal determined by the terminal from the first set of synchronization signals should satisfy one or more of the following:

[0253] The channel quality of one or more first synchronization signals associated with the second synchronization signal is higher than the channel quality of one or more first synchronization signals associated with the one or more third synchronization signals; that is, the second synchronization signal includes the synchronization signal with the best channel quality in the set of first synchronization signals.

[0254] The average channel quality of one or more first synchronization signals associated with the second synchronization signal is higher than the average channel quality of one or more first synchronization signals associated with the one or more third synchronization signals; that is, the second synchronization signal includes the synchronization signal with the best average channel quality in the set of first synchronization signals.

[0255] The index of the second synchronization signal is less than the index of the one or more third synchronization signals; that is, the second synchronization signal includes the synchronization signal with the smallest index in the first set of synchronization signals.

[0256] The number of first synchronization signals associated with the second synchronization signal that satisfy the first condition is greater than the number of first synchronization signals associated with the one or more third synchronization signals that satisfy the first condition.

[0257] The number of first synchronization signals that satisfy the second condition associated with the second synchronization signal is greater than the number of first synchronization signals that satisfy the second condition associated with the one or more third synchronization signals;

[0258] The second synchronization signal is a synchronization signal randomly selected from the first set of synchronization signals.

[0259] In practical applications, the synchronization signal requested by the terminal should at least meet the terminal's requirements, such as satisfying channel quality conditions. Therefore, the terminal can first filter out synchronization signals that satisfy the first or second condition from the first set of synchronization signals, and then determine the second synchronization signal from the filtered synchronization signals. In this case, one or more first synchronization signals corresponding to the third synchronization signal also satisfy the first or second condition. That is, in one embodiment, among all the first synchronization signals associated with each of the one or more third synchronization signals, there are one or more first synchronization signals that satisfy the first condition, or there are one or more first synchronization signals that satisfy the second condition respectively.

[0260] In practical applications, the terminal can use the synchronization signal transmission pattern of the second cell configured on the network side to determine which synchronization signals(s) of the second cell can actually be transmitted. In this case, the second synchronization signal should belong to the synchronization signals actually transmitted in the second cell. The synchronization signal transmission pattern of the second cell can be predefined, or the terminal can receive the synchronization signal transmission pattern of the second cell sent by the network side. The signaling for transmitting the synchronization signal transmission pattern of the second cell can be the same as or different from the signaling for transmitting the first information. The first information and the synchronization signal transmission pattern of the second cell can be transmitted simultaneously, or the synchronization signal transmission pattern of the second cell can be transmitted separately.

[0261] As can be seen from the above description, the terminal can use the received first information and the synchronization signal of the first cell, combined with predefined conditions, to determine a second synchronization signal that meets the terminal's requirements (such as beam direction requirements or channel quality requirements). Of course, if the second cell does not have a synchronization signal that meets the terminal's requirements, the terminal may not execute step 303, that is, it may not wake up the second cell, in order to ensure energy saving in the cell.

[0262] After determining the second synchronization signal, in step 303, the terminal can send a first uplink signal to the second cell to request the second cell to send the second synchronization signal.

[0263] In practical applications, the transmission power of the terminal sending the first uplink signal can be configured according to actual needs. For example, the transmission power of the first uplink signal can be configured to use the maximum transmission power supported by the terminal. That is, in one embodiment, the transmission power of the first uplink signal can be the maximum transmission power supported by the terminal. Of course, the transmission power of the first uplink signal can also be configured so that the terminal uses the minimum transmission power among one or more first transmission powers and the maximum transmission power supported by the terminal. That is, in one embodiment, the transmission power of the first uplink signal can be the minimum value between the maximum transmission power supported by the terminal and the first transmission power. The first transmission power can be predefined or configured on the network side. When the first transmission power is configured on the network side, in one embodiment, the method may further include: receiving fourth information, the fourth information being used to indicate the first transmission power; the signaling for transmitting the fourth information can be the same as or different from the signaling for transmitting the first information; the first information and the fourth information can be transmitted simultaneously, or the fourth information can be transmitted separately.

[0264] In practical applications, the terminal can send the first uplink signal at multiple transmission opportunities (also understood as transmission opportunities). That is, in one embodiment, the first uplink signal corresponds to N transmission opportunities, where N is an integer greater than 1. The value of N can be predefined according to actual needs; that is, in one embodiment, N is a predefined value. Alternatively, the value of N can be configured by the network side; that is, in one embodiment, the method can further include: receiving fifth information, which indicates the value of N; wherein the signaling for transmitting the fifth information can be the same as or different from the signaling for transmitting the first information; the first information and the fifth information can be transmitted simultaneously, or the fifth information can be transmitted separately.

[0265] In practical applications, after the terminal sends the first uplink signal, the network device of the second cell can send the second synchronization signal based on the received first uplink signal, so that the terminal can receive the second synchronization signal of the second cell and use the second synchronization signal to perform initial access and other operations.

[0266] Accordingly, embodiments of this application also provide a communication method applied to network devices, such as... Figure 5 As shown, the method includes:

[0267] Step 501: Send first information, the first information being used to indicate that the second synchronization signal of the second cell is associated with one or more first synchronization signals of the first cell;

[0268] Step 502: Send one or more first synchronization signals;

[0269] Step 503: Receive a first uplink signal, which is used to request the second synchronization signal.

[0270] In practical applications, the first cell (which may be the network device of the first cell) that is associated with (e.g., adjacent to) the second cell can inform the terminals within the service range of the first cell that there is a second cell in a power-saving state (i.e., a state in which no synchronization signal is sent by default). Thus, when the terminal needs to obtain a synchronization signal, it can send an uplink signal to the second cell to request the second cell to start sending a synchronization signal, which can also be understood as waking up the second cell.

[0271] In practical applications, in step 501, the network device (specifically including the network device associated with the first cell) sends (specifically, broadcasts) the first information to inform the terminals within the range of the first cell of the association relationship (or association configuration) between the synchronization signal of the first cell and the synchronization signal of the second cell. Here, step 501 can also be understood as: the network device sends the first information in the first cell.

[0272] After sending the first information, in step 502, the network device sends (specifically, broadcasts) a synchronization signal of the first cell, so that the terminal can determine, based on the received synchronization signal of the first cell and the first information, from one or more synchronization signals of the second cell the second cell needs to be woken up (i.e., the second cell needs to be requested to send a second synchronization signal). Here, step 501 can also be understood as: the network device sends the one or more first synchronization signals in the first cell.

[0273] After receiving the first information and one or more first synchronization signals, the terminal can determine which synchronization signals(i) need to be woken up (i.e., determine the second synchronization signal) by judging whether the synchronization signals of one or more first cells corresponding to each synchronization signal of the second cell meet the relevant conditions. All synchronization signals of the first cell may correspond to the same conditions, or each synchronization signal of the first cell may correspond to its own specific conditions.

[0274] In practical applications, when all synchronization signals in the first cell correspond to the same conditions, one or more of the first synchronization signals associated with the second synchronization signal satisfy the first condition, wherein the first condition may include one of the following:

[0275] The channel quality is greater than the first threshold;

[0276] The channel quality is less than the second threshold;

[0277] The channel quality is greater than the third threshold and less than the fourth threshold;

[0278] In one embodiment, the method may further include:

[0279] The system sends a second information message, which indicates one or more of a first threshold, a second threshold, a third threshold, and a fourth threshold. Specifically, the first threshold is used by the terminal to determine whether the channel quality of one or more first synchronization signals associated with the second synchronization signal is greater than the first threshold; the second threshold is used by the terminal to determine whether the channel quality of one or more first synchronization signals associated with the second synchronization signal is less than the second threshold; and the third and fourth thresholds are used by the terminal to determine whether the channel quality of one or more first synchronization signals associated with the second synchronization signal is greater than the third threshold and less than the fourth threshold. The second information can also be understood as threshold configuration information. The signaling for transmitting the second information can be the same as or different from the signaling for transmitting the first information. The first and second information can be transmitted simultaneously, or the second information can be transmitted separately.

[0280] In practical applications, given that each synchronization signal in the first cell corresponds to its own condition, one or more of the one or more first synchronization signals associated with the second synchronization signal satisfy the corresponding second condition, wherein the second condition may include one of the following:

[0281] The channel quality is greater than the corresponding fifth threshold;

[0282] The channel quality is less than the corresponding sixth threshold;

[0283] The channel quality is greater than the corresponding seventh threshold and less than the corresponding eighth threshold;

[0284] In one embodiment, the method may further include:

[0285] A third piece of information is sent, which indicates one or more of a fifth threshold, a sixth threshold, a seventh threshold, and an eighth threshold. Specifically, the fifth threshold is used by the terminal to determine whether the channel quality of one or more first synchronization signals associated with the second synchronization signal is greater than the fifth threshold; the sixth threshold is used by the terminal to determine whether the channel quality of one or more first synchronization signals associated with the second synchronization signal is less than the sixth threshold; and the seventh and eighth thresholds are used by the terminal to determine whether the channel quality of one or more first synchronization signals associated with the second synchronization signal is greater than the seventh threshold and less than the eighth threshold. The third information can also be understood as threshold configuration information. The signaling transmitting the third information can be the same as or different from the signaling transmitting the first information. The first information and the third information can be transmitted simultaneously, or the third information can be transmitted separately.

[0286] In practical applications, after determining the second synchronization signal, the terminal needs to send an uplink signal (i.e., a first uplink signal) to the second cell to request the second cell to send the second synchronization signal. At this time, the terminal can send the first uplink signal using the maximum transmission power it supports; alternatively, the terminal can also send the first uplink signal using the minimum transmission power among one or more configured transmission powers and the maximum transmission power it supports. That is, the transmission power of the first uplink signal can be one of the following:

[0287] The maximum transmission power supported by the terminal;

[0288] The minimum value between the maximum transmission power supported by the terminal and the first transmission power; wherein, the first transmission power refers to one or more pre-configured transmission powers;

[0289] When the transmission power of the first uplink signal is the minimum of the maximum transmission power supported by the terminal and the first transmission power, the network device can configure the first transmission power for the terminal. That is, in one embodiment, the method may further include:

[0290] A fourth piece of information is sent, which indicates the first transmission power. The first transmission power is used to determine the transmission power of the first uplink signal.

[0291] In practical applications, the terminal can send the first uplink signal to the second cell at multiple transmission opportunities (also understood as transmission opportunities). That is, the first uplink signal can correspond to N transmission opportunities, where N is an integer greater than 1. In this case, the network device can configure the value of N for the terminal. In other words, in one embodiment, the method may further include:

[0292] A fifth message is sent, which indicates the value of N. The value of N is used to determine the number of times the first uplink signal is sent.

[0293] In practical applications, when the first cell and the second cell share the same site, the network equipment of the first cell and the network equipment of the second cell are the same (i.e., the first cell and the second cell have the same network equipment). In this case, in step 503, the network equipment receives the first uplink signal sent by the terminal in the second cell. Then, the network equipment can send the second synchronization signal in the second cell based on the first uplink signal, so that the terminal can receive the second synchronization signal of the second cell and use the second synchronization signal to perform initial access and other operations.

[0294] Of course, when the first cell and the second cell are not co-located, the network device associated with the second cell (i.e., the network device of the second cell) can receive the first uplink signal sent by the terminal. Then, the network device associated with the second cell can send the second synchronization signal based on the first uplink signal, so that the terminal can receive the second synchronization signal of the second cell. That is to say, the process of waking up the second cell to send the synchronization signal includes: the network device of the first cell sends the first information and one or more first synchronization signals; the terminal receives the first information and one or more first synchronization signals in the first cell; then, the terminal sends the first uplink signal to the network device of the second cell; the network device of the second cell receives the first uplink signal sent by the terminal and sends the second synchronization signal corresponding to the first uplink signal; finally, the terminal receives the second synchronization signal in the second cell, thereby enabling operations such as access performance evaluation of the second cell.

[0295] This application also provides a communication method, such as... Figure 6 As shown, the method includes:

[0296] Step 601: The network device sends first information, which is used to indicate that the second synchronization signal of the second cell is associated with one or more first synchronization signals of the first cell;

[0297] Step 602: The terminal receives the first information;

[0298] Step 603: The network device sends one or more first synchronization signals;

[0299] Step 604: The terminal receives one or more first synchronization signals;

[0300] Step 605: The terminal sends a first uplink signal, which is used to request the second synchronization signal;

[0301] Step 606: The network device receives the first uplink signal.

[0302] It should be noted that the specific processing procedures for terminals and network devices have been detailed above and will not be repeated here.

[0303] The communication method provided in this application embodiment involves a network device sending first information, which indicates that a second synchronization signal of a second cell is associated with one or more first synchronization signals of a first cell; a terminal receiving the first information; the network device sending the one or more first synchronization signals; the terminal receiving the one or more first synchronization signals; the terminal sending a first uplink signal, which requests the second synchronization signal; and the network device receiving the first uplink signal. The solution provided in this application embodiment allows a cell (e.g., the second cell) to not send any synchronization signals by default, and the terminal needs to obtain the synchronization signal of that cell. Network devices in other cells related to that cell (e.g., the first cell) configure the association between the synchronization signals of other cells and the synchronization signal of that cell for the terminal. This enables the terminal to use the received synchronization signals of other cells, combined with the association, to determine how to send a wake-up signal (i.e., the first uplink signal), thereby triggering the network side to send a synchronization signal (i.e., the second synchronization signal) that meets the terminal's requirements.

[0304] Next, in a scenario where energy saving is achieved in a residential community by sending long-period synchronization signals, this application embodiment also provides a communication method applied to a terminal, such as... Figure 7 As shown, the method includes:

[0305] Step 701: Receive a fourth synchronization signal, the fourth synchronization signal containing sixth information, the sixth information including one or more of the following:

[0306] Frequency domain configuration information for the second uplink signal;

[0307] Time-domain configuration information of the second uplink signal;

[0308] Code field configuration information for the second uplink signal;

[0309] Power configuration information for the second uplink signal;

[0310] Step 702: Based on the sixth information, send the second uplink signal; wherein the second uplink signal is used to request the fifth synchronization signal.

[0311] In practical applications, the fourth synchronization signal can include a synchronization signal with a longer period (e.g., 160ms). This allows the network to achieve energy savings in the cell by sending the fourth synchronization signal. Specifically, the frequency domain location of the fourth synchronization signal (e.g., the synchronization grid) is independent of the frequency domain location of the fifth synchronization signal with a shorter period (e.g., 20ms).

[0312] However, in practical applications, if a terminal within the cell needs to obtain a synchronization signal for initial access or other operations, the fourth synchronization signal may be insufficient to meet the terminal's requirements. In this case, such as Figure 8 As shown, the terminal can send an uplink signal (i.e., a second uplink signal) to the network side to request the network side to send a fifth synchronization signal that meets its requirements. The type of the fourth synchronization signal can specifically be one of SSB, PBCH, PSS, SSS, LP-SS, or a newly defined synchronization signal type in 6G; the type of the fifth synchronization signal can specifically be one of SSB, PBCH, PSS, SSS, LP-SS, or a newly defined synchronization signal type in 6G; this application embodiment does not limit the names and specific implementations of the fourth and fifth synchronization signals.

[0313] In practical applications, the network side instructs the terminal on how to send the second uplink signal through the sixth information carried in the fourth synchronization signal. That is, the sixth information includes the transmission configuration of the second uplink signal. Here, the sixth information can also be understood as instruction information, and the name of the sixth information is not limited in this embodiment.

[0314] Specifically, the method by which the fourth synchronization signal carries the sixth information may include one or more of the following:

[0315] In terms of display method, specifically, the first field in the fourth synchronization signal contains the sixth information;

[0316] In an implicit manner, specifically, the sixth information is determined using relevant information from the fourth synchronization signal, wherein the relevant information from the fourth synchronization signal includes one or more of the following:

[0317] The frequency domain position in the fourth synchronization signal;

[0318] The sequence value in the fourth synchronization signal;

[0319] The cyclic displacement value in the fourth synchronization signal;

[0320] The encoded sequence in the fourth synchronization signal (e.g., the PBCH payload);

[0321] The pilot resources associated with the fourth synchronization signal; wherein the pilot resources include time-frequency resources of the pilot (such as resource elements (REs) of the PBCH demodulation reference signal (DM-RS)) or pilot sequences (such as sequences of PBCH DM-RS).

[0322] Specifically, the sixth information can be used to instruct the terminal to transmit one or more of the time domain, frequency domain, code domain, and power related to the second uplink signal. The following discussion addresses each configuration information indicated by the sixth information:

[0323] 1) When the sixth information indicates the frequency domain configuration information of the second uplink signal, in one embodiment, the frequency domain configuration information may include one or more of the following:

[0324] The seventh information is used to indicate the frequency band where the second uplink signal is located, or the seventh information is used to indicate one of one or more predefined frequency band combinations, each frequency band combination being associated with a frequency band where a fourth synchronization signal is located and a frequency band where a second uplink signal is located;

[0325] The eighth piece of information is used to indicate the frequency domain start position of the second uplink signal;

[0326] The ninth information is used to indicate the number of frequency domain resource units corresponding to the second uplink signal.

[0327] Specifically, the eighth information can indicate the offset between the frequency domain start position of the second uplink signal and the first subcarrier or first RB of the frequency band in which the second uplink signal is located. In one embodiment, the eighth information includes tenth information, which indicates the offset between the frequency domain start position of the second uplink signal and the start position of the start subcarrier or start RB of the frequency band in which the second uplink signal is located. Alternatively, the eighth information can also specifically indicate the offset between the frequency domain start position of the second uplink signal and the frequency domain start position of the fourth synchronization signal. In one embodiment, the eighth information includes eleventh information, which indicates the frequency domain offset between the frequency domain start position of the second uplink signal and the frequency domain start position of the fourth synchronization signal.

[0328] In practical applications, the seventh information can indicate that one of one or more predefined frequency bands is the frequency band where the second uplink signal is located. In this case, the terminal can directly determine to send the second uplink signal in the frequency band indicated by the seventh information. Alternatively, the seventh information can indicate one of the predefined combinations of one or more frequency bands. In this case, the terminal can use the frequency band of the fourth synchronization signal in combination with the frequency band combination indicated by the seventh information to determine the frequency band for sending the second uplink signal. Furthermore, if the system used is a Time Division Duplexing (TDD) system (i.e., the parameters in the fourth synchronization signal indicate that the corresponding system is a TDD system), or if the network side has not configured the seventh information for the terminal (i.e., the sixth information does not include the seventh information), the terminal can use the frequency band of the fourth synchronization signal as the frequency band for sending the second uplink signal. The system used refers to the system standard currently used by the terminal. In actual application, the terminal can determine the system standard currently used by the terminal through the sixth information. That is, in one embodiment, the sixth information is used to indicate the system standard used, which can be TDD or Frequency Division Duplexing (FDD).

[0329] When the eighth information includes the tenth information, the eighth information can specifically indicate one of one or more predefined offset values. In this case, the terminal can use the frequency band where the second uplink signal is located and the offset value indicated by the tenth information to determine the frequency domain starting position for transmitting the second uplink signal. Conversely, when the eighth information includes the eleventh information, the eighth information can specifically indicate one of one or more predefined frequency domain offsets. In this case, the terminal can use the frequency band where the fourth synchronization signal is located and the frequency domain offset indicated by the eleventh information to determine the frequency domain starting position for transmitting the second uplink signal. Furthermore, if the system standard used is TDD, or if the sixth information does not include the eighth information, the terminal can use the frequency domain position of the fourth synchronization signal (e.g., the center frequency) as the frequency domain position of the second uplink signal. Alternatively, the terminal can use the first subcarrier or RB of the frequency band where the second uplink signal is located as the frequency domain starting position of the second uplink signal.

[0330] Regarding the ninth information, it may indicate one of a predefined number of frequency domain resource units (or frequency domain resource values, etc.). In this case, the terminal may use the number of frequency domain resource units indicated by the ninth information for transmitting the second uplink signal. Simultaneously, if the sixth information does not include the ninth information, the terminal may transmit the second uplink signal based on predefined frequency domain resources (such as the number of frequency domain resource units).

[0331] 2) When the sixth information indicates the time-domain configuration information of the second uplink signal, in one embodiment, the time-domain configuration information may include one or more of the following:

[0332] The twelfth information is used to indicate the time-domain offset of the transmission timing of the second uplink signal relative to the transmission timing of the fourth synchronization signal;

[0333] The thirteenth information is used to indicate the time-domain pattern corresponding to the actual transmission timing used to transmit the second uplink signal;

[0334] The fourteenth information is used to indicate the number of time-domain resource units corresponding to the second uplink signal.

[0335] In practical applications, the twelfth information may indicate one of a predefined time-domain offset values. In this case, the terminal can use the time-domain start position of the fourth synchronization signal (which can also be understood as the transmission timing) in conjunction with the time-domain offset value indicated by the twelfth information to determine the time-domain start position for sending the second uplink signal. Furthermore, if the system standard used is FDD, or if the sixth information does not include the twelfth information, the terminal can use the time-domain start position of the fourth synchronization signal as the time-domain start position for sending the second uplink signal, i.e., the time-domain offset value is 0.

[0336] Regarding the thirteenth information, the thirteenth information may indicate one of the time-domain patterns in a predefined time-domain pattern of one or more transmission opportunities. In this case, the terminal may send the second uplink signal based on the time-domain pattern indicated by the thirteenth information. Simultaneously, if the system used is an FDD system, or if the sixth information does not contain the thirteenth information, the terminal may use the transmission pattern corresponding to the fourth synchronization signal as the transmission pattern of the second uplink signal.

[0337] Regarding the fourteenth piece of information, it may indicate one of a predefined number of time-domain resource units (or time-domain resource values, etc.). In this case, the terminal may use the number of time-domain resource units indicated by the fourteenth piece of information for transmitting the second uplink signal. Simultaneously, if the sixth piece of information does not include the fourteenth piece of information, the terminal may transmit the second uplink signal based on predefined time-domain resources (such as the number of time-domain resource units).

[0338] 3) When the sixth information indicates the code field configuration information of the second uplink signal, in one embodiment, the code field configuration information may include one or more of the following:

[0339] Community identification information, such as the cell ID;

[0340] The cell identification information and the index value of the fourth synchronization signal.

[0341] In practical applications, the terminal can determine the first sequence (which can also be understood as the transmission sequence or the sequence of the second uplink signal) to be sent based on the code field configuration information.

[0342] Specifically, when the code domain configuration information includes cell identifier information, the cell identifier information can indicate one of one or more predefined cell identifiers, so that the terminal can determine the first sequence of the first uplink signal. That is, in one embodiment, the method may further include: the terminal determining the first sequence of the second uplink signal based on the cell identifier information. Specifically, the terminal can generate the first sequence based on the cell identifier indicated by the cell identifier information; of course, the terminal can also input the cell identifier into a first module to obtain the first sequence output by the first module. The first module refers to a module used to generate the sequence. This application embodiment does not limit the name and specific implementation of the first module. Here, a module can also be understood as a model or unit, etc., and this application embodiment does not limit it in this way.

[0343] When the code field configuration information includes cell identifier information and the index value of the fourth synchronization signal, the cell identifier information can indicate one of one or more predefined cell identifiers, and the index value of the fourth synchronization signal can indicate one of one or more predefined index values, so that the terminal can determine the first sequence of the first uplink signal. That is, in one embodiment, the method may further include: determining the first sequence of the second uplink signal based on the cell identifier information and the index value of the fourth synchronization signal. Specifically, the terminal may generate the first sequence based on the cell identifier indicated by the cell identifier information and the index value of the fourth synchronization signal; of course, the terminal may also input the cell identifier and the index value of the fourth synchronization signal into the first module to obtain the first sequence output by the first module.

[0344] 4) When the sixth information indicates the power configuration information of the second uplink signal, in one embodiment, the power configuration information may include one or more of the following:

[0345] The fifteenth piece of information is used to indicate the second transmission power;

[0346] The sixteenth information is used to indicate the target receive power of the second uplink signal and / or the transmit power of the fourth synchronization signal.

[0347] In practical applications, the transmission power of the terminal sending the second uplink signal can be configured according to actual needs. For example, the transmission power of the second uplink signal can be configured to use the maximum transmission power supported by the terminal. That is, in one embodiment, the transmission power of the second uplink signal can be the maximum transmission power supported by the terminal. Of course, the transmission power of the second uplink signal can also be configured so that the terminal uses the minimum transmission power among one or more second transmission powers and the maximum transmission power supported by the terminal. That is, in one embodiment, the transmission power of the second uplink signal can be the minimum value between the maximum transmission power supported by the terminal and the second transmission power. In one embodiment, the second transmission power is predefined; or, the second transmission power can be determined based on the power configuration information. That is, in one embodiment, the method may further include: determining the second transmission power according to the power configuration information of the second uplink signal.

[0348] In practical applications, the fifteenth information may indicate one of one or more predefined transmission powers. In this case, the terminal may use the transmission power indicated by the fifteenth information as the second transmission power.

[0349] Regarding the sixteenth piece of information, the sixteenth piece of information may indicate a transmission power among one or more predefined transmission powers of the fourth synchronization signals, and / or a target reception power among one or more predefined target reception powers of the second uplink signals; in this case, the terminal can use the reception power of the fourth synchronization signal and the sixteenth piece of information to determine the second transmission power of the second uplink signal. Specifically, in one embodiment, determining the second transmission power based on the power configuration information of the second uplink signal includes:

[0350] The path loss is determined based on the transmission power and reception power of the fourth synchronization signal.

[0351] The second transmit power is determined based on the path loss and the target receive power of the second uplink signal.

[0352] In practical applications, the terminal can use the received power of the fourth synchronization signal and the transmitted power of the fourth synchronization signal indicated by the sixteenth information to determine the path loss (specifically including the path loss value) between the terminal and the network side; then, the terminal uses the path loss and the target received power of the second uplink signal indicated by the sixteenth information to determine the second transmitted power. Specifically, the path loss can be expressed as: received power of the fourth synchronization signal - transmitted power of the fourth synchronization signal; the second transmitted power can be expressed as: target received power of the second uplink signal + path loss.

[0353] As can be seen from the above description, the terminal can use the sixth information contained in the fourth synchronization signal to determine the relevant configuration for sending the second uplink signal; then, in step 602, the terminal sends the second uplink signal based on the relevant configuration.

[0354] When the network side sends multiple synchronization signals in power-saving mode, these multiple synchronization signals can be used as a second synchronization signal set. In this case, if the sixth information (i.e., uplink signal configuration information) contained in each synchronization signal in the second synchronization signal set is exactly the same, the terminal can use any synchronization signal as the fourth synchronization signal and use the sixth information contained in the fourth synchronization signal to determine how to send the second uplink signal. Of course, if the sixth information contained in each synchronization signal in the second synchronization signal set is not exactly the same, the terminal can determine from the second synchronization signal set the synchronization signal that meets the terminal's requirements (such as channel quality requirements or signal strength requirements) as the fourth synchronization signal and use the sixth information contained in the fourth synchronization signal to determine how to send the second uplink signal. In one embodiment, the fourth synchronization signal determined by the terminal from the multiple synchronization signals contained in the second synchronization signal set should satisfy one or more of the following:

[0355] The channel quality of the fourth synchronization signal is higher than that of the one or more sixth synchronization signals;

[0356] The index of the fourth synchronization signal is less than the index of the one or more sixth synchronization signals;

[0357] The fourth synchronization signal is a synchronization signal randomly selected from the second set of synchronization signals.

[0358] In practical applications, the same third condition can be set for all synchronization signals in the second set of synchronization signals. In this case, the determined fourth synchronization signal should at least satisfy the third condition. That is, in one embodiment, the fourth synchronization signal satisfies the third condition and each of the one or more sixth synchronization signals satisfies the third condition. In one embodiment, the third condition may include one of the following:

[0359] The channel quality is greater than the ninth threshold;

[0360] Channel quality is less than the tenth threshold;

[0361] The channel quality is greater than the eleventh threshold and less than the twelfth threshold.

[0362] In practical applications, the ninth, tenth, eleventh, and twelfth thresholds can be predefined. That is, in one embodiment, one or more of the ninth, tenth, eleventh, and twelfth thresholds are predefined. Alternatively, the network side can configure the ninth, tenth, eleventh, and twelfth thresholds. In another embodiment, the method may further include receiving seventeenth information, which indicates one or more of the ninth, tenth, eleventh, and twelfth thresholds. Specifically, the terminal can obtain the seventeenth information through one or more synchronization signals in the second synchronization signal group.

[0363] Of course, a corresponding fourth condition can also be set for each synchronization signal in the second set of synchronization signals. In this case, the determined fourth synchronization signal should at least satisfy the fourth condition. That is, in one embodiment, the fourth synchronization signal satisfies the corresponding fourth condition, and each of the one or more sixth synchronization signals satisfies the corresponding fourth condition. In one embodiment, the fourth condition may include one of the following:

[0364] The channel quality is greater than the corresponding thirteenth threshold;

[0365] The channel quality is less than the corresponding fourteenth threshold;

[0366] The channel quality is greater than the corresponding fifteenth threshold and less than the corresponding sixteenth threshold.

[0367] In practical applications, the thirteenth, fourteenth, fifteenth, and sixteenth thresholds can be predefined. That is, in one embodiment, one or more of the thirteenth, fourteenth, fifteenth, and sixteenth thresholds are predefined. Alternatively, the thirteenth, fourteenth, fifteenth, and sixteenth thresholds can be configured by the network side. In other words, in one embodiment, the method may further include receiving eighteenth information, which indicates one or more of the thirteenth, fourteenth, fifteenth, and sixteenth thresholds. Specifically, the terminal can obtain the eighteenth information through one or more synchronization signals in the second synchronization signal group.

[0368] In practical applications, after the terminal sends the second uplink signal, the network side can send the fifth synchronization signal based on the received second uplink signal, so that the terminal can perform initial access and other operations.

[0369] Accordingly, embodiments of this application also provide a communication method applied to network devices, such as... Figure 9 As shown, the method includes:

[0370] Step 901: Send a fourth synchronization signal, the fourth synchronization signal containing sixth information, the sixth information including one or more of the following:

[0371] Frequency domain configuration information for the second uplink signal;

[0372] Time-domain configuration information of the second uplink signal;

[0373] Code field configuration information for the second uplink signal;

[0374] Power configuration information for the second uplink signal;

[0375] Step 902: Receive the second uplink signal, which is used to request the fifth synchronization signal.

[0376] In practical applications, the network device sends a longer-period fourth synchronization signal in energy-saving mode, instead of a shorter-period fifth synchronization signal. However, if a terminal within the cell needs to obtain a synchronization signal for initial access or other operations, the fourth synchronization signal may not meet the terminal's requirements. In this case, the terminal can use the sixth information contained in the fourth synchronization signal to determine the method for sending the second uplink signal and send the second uplink signal to the network device. Then, in step 802, the network device receives the second uplink signal and can send the fifth synchronization signal based on the second uplink signal to meet the terminal's requirements.

[0377] In practical applications, the network device can send multiple synchronization signals in energy-saving mode. The sixth information (i.e., uplink signal configuration information) corresponding to each of these multiple synchronization signals may not be completely identical. In this case, the multiple synchronization signals sent by the network device can be considered as a second synchronization signal set. This second synchronization signal set includes the fourth synchronization signal and one or more sixth synchronization signals. To ensure that the synchronization signals requested by the terminal from the network device meet its requirements (such as channel quality requirements or signal strength requirements), the network device can configure the conditions that the fourth synchronization signal must meet for the terminal.

[0378] Specifically, the network side can set the same third condition for all synchronization signals in the second synchronization signal set. In this case, the fourth synchronization signal satisfies the third condition, and each of the one or more sixth synchronization signals satisfies the third condition. The third condition may include one of the following:

[0379] The channel quality is greater than the ninth threshold;

[0380] Channel quality is less than the tenth threshold;

[0381] The channel quality is greater than the eleventh threshold and less than the twelfth threshold;

[0382] In this context, in one embodiment, the method may further include:

[0383] The seventeenth message is sent, which indicates one or more of the ninth, tenth, eleventh, and twelfth thresholds. Specifically, the ninth threshold is used by the terminal to determine whether the channel quality of one or more first synchronization signals associated with the second synchronization signal is greater than the ninth threshold; the tenth threshold is used by the terminal to determine whether the channel quality of one or more first synchronization signals associated with the second synchronization signal is less than the tenth threshold; and the eleventh and twelfth thresholds are used by the terminal to determine whether the channel quality of one or more first synchronization signals associated with the second synchronization signal is greater than the eleventh threshold and less than the twelfth threshold.

[0384] Of course, the network side can also set a corresponding fourth condition for each synchronization signal in the second set of synchronization signals. In this case, the fourth synchronization signal satisfies the corresponding fourth condition, and each of the one or more sixth synchronization signals satisfies the corresponding fourth condition. The fourth condition may include one of the following:

[0385] The channel quality is greater than the corresponding thirteenth threshold;

[0386] The channel quality is less than the corresponding fourteenth threshold;

[0387] The channel quality is greater than the corresponding fifteenth threshold and less than the corresponding sixteenth threshold;

[0388] In this context, in one embodiment, the method may further include:

[0389] The eighteenth message is sent, which indicates one or more of the thirteenth, fourteenth, fifteenth, and sixteenth thresholds. Specifically, the thirteenth threshold is used by the terminal to determine whether the channel quality of one or more first synchronization signals associated with the second synchronization signal is greater than the thirteenth threshold; the fourteenth threshold is used by the terminal to determine whether the channel quality of one or more first synchronization signals associated with the second synchronization signal is less than the fourteenth threshold; and the fifteenth and sixteenth thresholds are used by the terminal to determine whether the channel quality of one or more first synchronization signals associated with the second synchronization signal is greater than the fifteenth threshold and less than the sixteenth threshold.

[0390] This application also provides a communication method, such as... Figure 10 As shown, the method includes:

[0391] Step 1001: The network device sends a fourth synchronization signal, the fourth synchronization signal containing sixth information, the sixth information including one or more of the following:

[0392] Frequency domain configuration information for the second uplink signal;

[0393] Time-domain configuration information of the second uplink signal;

[0394] Code field configuration information for the second uplink signal;

[0395] The power configuration information of the second uplink signal; wherein the second uplink signal is used to request the fifth synchronization signal;

[0396] Step 1002: The terminal receives the fourth synchronization signal;

[0397] Step 1003: The terminal sends the second uplink signal according to the sixth information;

[0398] Step 1004: The network device receives the second uplink signal.

[0399] It should be noted that the specific processing procedures for terminals and network devices have been detailed above and will not be repeated here.

[0400] The communication method provided in this application embodiment involves a network device sending a fourth synchronization signal. The fourth synchronization signal includes sixth information, which includes one or more of the following: frequency domain configuration information of a second uplink signal; time domain configuration information of a second uplink signal; code domain configuration information of a second uplink signal; and power configuration information of a second uplink signal. The second uplink signal is used to request a fifth synchronization signal. A terminal receives the fourth synchronization signal. The terminal sends the second uplink signal according to the sixth information. The network device receives the second uplink signal. In the solution provided in this application embodiment, when the default synchronization signal (i.e., the fourth synchronization signal) sent by a certain cell cannot meet the terminal's requirements, the terminal can send a wake-up signal based on the configuration information related to sending a wake-up signal (i.e., the second uplink signal) issued by the network side, thereby triggering the network side to send a synchronization signal (i.e., the fifth synchronization signal) that can meet the terminal's requirements.

[0401] The following section provides a more detailed description of this application with reference to application examples.

[0402] In related technologies, a cell can achieve energy saving by default not sending synchronization signals (i.e., no synchronization signal transmission) or by default sending long-period synchronization signals (long-period synchronization signal transmission).

[0403] In scenarios where synchronization signals are not transmitted, this application example proposes a method for triggering synchronization signals (specifically, SSBs) on demand, such as... Figure 11 As shown, it includes the following steps:

[0404] Step 1101: The network device of the first cell sends (or can be understood as sending in the first cell) the first configuration information (i.e. the first information mentioned above), the first configuration information including the association configuration of the first synchronization signal and the second synchronization signal;

[0405] The first synchronization signal can be transmitted on the first cell, and the second synchronization signal can be transmitted on the second cell. The association configuration of the first and second synchronization signals can specifically indicate the correspondence between the second and first synchronization signals, and the correspondence can include one of the following:

[0406] Each second synchronization signal corresponds one-to-one with a first synchronization signal;

[0407] One first synchronization signal can correspond to multiple second synchronization signals;

[0408] One second synchronization signal can correspond to multiple first synchronization signals.

[0409] Specifically, the network equipment (such as base stations) of the first cell can broadcast the first configuration information to inform the terminals in the first cell of the correspondence between the first synchronization signal and the second synchronization signal.

[0410] In practical applications, when the first cell and the second cell are not co-located, the association configuration of the first synchronization signal and the second synchronization signal can also indicate the channel quality threshold corresponding to the second synchronization signal.

[0411] Step 1102: The terminal receives the first configuration information in the first cell;

[0412] Step 1103: The network device sends one or more first synchronization signals; that is, it sends the one or more first synchronization signals in the first cell;

[0413] Step 1104: The terminal receives one or more first synchronization signals;

[0414] Step 1105: The terminal sends a first uplink signal, which is used to trigger (or request) a third synchronization signal (i.e., the aforementioned second synchronization signal), and the third synchronization signal belongs to the one or more second synchronization signals (i.e., the aforementioned first synchronization signal set);

[0415] In practical applications, the first uplink signal sent by the terminal can be used to trigger the network device of the second cell to send the third synchronization signal. At the same time, it can also be used to trigger the network device of the second cell to send system information of the second cell associated with the third synchronization signal, such as SIB1 of the second cell.

[0416] In practical applications, the terminal may determine the third synchronization signal from the one or more second synchronization signals in one or more of the following ways:

[0417] 1) If there are one or more second synchronization signals, and each second synchronization signal is associated with one or more first synchronization signals that satisfy the channel quality threshold of the first cell, then any one of the one or more second synchronization signals shall be selected as the third synchronization signal.

[0418] 2) Select a third synchronization signal from one or more second synchronization signals, wherein the channel quality of one or more first synchronization signals associated with the third synchronization signal is optimal;

[0419] 3) The second synchronization signal with the smallest index is used as the third synchronization signal;

[0420] 4) Use any one or all of the second synchronization signals corresponding to all the first synchronization signals as the third synchronization signal;

[0421] 5) Using the transmission pattern of the second synchronization signal, determine one or more second synchronization signals actually transmitted in the second cell, and then determine the third synchronization signal from the one or more second synchronization signals actually transmitted.

[0422] The channel quality threshold is defined as either greater than a configured threshold, falling within a configured set of threshold intervals, or less than a configured threshold. All first synchronization signals in the first cell share the same channel quality threshold (i.e., one or more of the aforementioned first, second, third, and fourth thresholds); or, each first synchronization signal in the first cell corresponds to a separate channel quality threshold (i.e., one or more of the aforementioned fifth, sixth, seventh, and eighth thresholds), and the channel quality thresholds corresponding to each first signal may be different. The transmission pattern of the second synchronization signal can be configured by the first cell; for example, the first configuration information may include the transmission pattern of the second synchronization signal.

[0423] In practical applications, if all the first synchronization signals received by the terminal do not meet the aforementioned channel quality threshold, the terminal may consider that all the second synchronization signals of the second cell are difficult to meet the requirements and determine not to send the first uplink signal.

[0424] In practical applications, the transmission power of the first uplink signal can be: the maximum transmission power supported by the terminal, or the minimum value between the maximum transmission power supported by the terminal and the first transmission power pre-configured by the network device.

[0425] In practical applications, the first uplink signal corresponds to multiple transmission opportunities. The number of these multiple transmission opportunities can be predefined or pre-configured by the network device.

[0426] Step 1106: The network equipment in the second cell receives the first uplink signal;

[0427] Step 1107: The network equipment in the second cell sends the third synchronization signal; that is, the third synchronization signal is sent in the second cell.

[0428] Specifically, when the terminal sends a first signal requesting all synchronization signals (i.e., all second synchronization signals) of the second cell, in step 1107, the network device of the second cell sends all second synchronization signals. Simultaneously, when sending the synchronization signals, the network device of the second cell also sends system information corresponding to the synchronization signals.

[0429] Step 1108: The terminal receives the third synchronization signal in the second cell.

[0430] The solution provided in the application example of this application designs and clarifies how to determine the third synchronization signal to be woken up when the terminal sends an uplink wake-up signal in a scenario where the energy-saving cell does not send a synchronization signal. Specifically, it addresses how to obtain the spatial information of the second cell (such as one or more of the channel quality, beam direction, and index of the second cell's synchronization signal). This enables the terminal to reliably wake up the synchronization signal of the energy-saving cell in this scenario.

[0431] In scenarios involving long-period synchronization signal transmission, this application example proposes a method for triggering synchronization signals on demand, such as... Figure 12 As shown, it includes the following steps:

[0432] Step 1201: The network device sends the fourth synchronization signal;

[0433] The terminal may assume that the fourth synchronization signal is sent at a fixed period, such as 170ms, and that the frequency domain position of the fourth synchronization signal (such as the synchronization grid) is independent of the frequency domain position of the fifth synchronization signal (such as the synchronization grid of the SSB).

[0434] Step 1202: The terminal receives the fourth synchronization signal (i.e., the aforementioned fourth synchronization signal);

[0435] Step 1203: The terminal determines the first information related to the second uplink signal based on the first indication information of the fourth synchronization signal (i.e., the sixth information mentioned above). The second uplink signal is used to trigger the fifth synchronization signal (i.e., the fifth synchronization signal mentioned above).

[0436] In practical applications, the fourth synchronization signal and the fifth synchronization signal can be the same or different. For example, when the fourth synchronization signal is LP-SS, the fifth synchronization signal is SSB.

[0437] In practical applications, the fourth synchronization signal can explicitly carry the indication information, for example, the first field of the fourth synchronization signal contains the first indication information. Alternatively, the fourth synchronization signal can also implicitly carry the first indication information, for example, the terminal can determine the knowledge information through the relevant information of the fourth synchronization signal, which includes one or more of the following:

[0438] The frequency domain location of the fourth synchronization signal;

[0439] The sequence value of the fourth synchronization signal;

[0440] The cyclic shift value of the fourth synchronization signal;

[0441] The encoded sequence of the fourth synchronization signal (e.g., PBCH payload);

[0442] The fourth synchronization signal pilot specifically includes the pilot time-frequency resources (such as the RE position of PBCH DM-RS) or pilot sequence (such as the sequence of PBCH DM-RS).

[0443] In practical applications, the first information related to the second uplink signal may include one or more of the following:

[0444] Frequency domain configuration for the second uplink signal transmission timing;

[0445] Time-domain configuration of the second uplink signal transmission opportunity;

[0446] The sequence corresponding to the second uplink signal;

[0447] The transmit power corresponding to the second uplink signal.

[0448] The frequency domain configuration for the second uplink signal transmission timing may include one or more of the following:

[0449] The frequency band combination corresponding to the frequency band where the fourth synchronization signal is located and the frequency band where the second uplink signal is located;

[0450] The frequency domain starting position of the second uplink signal in the frequency band;

[0451] The second uplink signal occupies frequency domain resources.

[0452] In practical applications, one or more frequency band combinations can be predefined, and one of the frequency band combinations can be indicated by the first indication information; or, when the parameters in the fourth synchronization signal indicate that the corresponding system is a TDD system, or when the first indication information does not contain information indicating the frequency band combination, the terminal can assume that the frequency band where the fourth synchronization signal is located is the same as the frequency band where the second uplink signal is located.

[0453] In practical applications, when the first indication information indicates a frequency band combination, the terminal can use the starting position of the first subcarrier or RB of the indicated frequency band combination as the frequency domain starting position of the second uplink signal; or, it can predefine one or more frequency domain offset values ​​(i.e., the offset value of the frequency domain starting position of the second uplink signal relative to the frequency domain starting position of the fourth synchronization signal), and indicate one of the frequency domain offset values ​​through the first indication information to determine the frequency domain starting position of the second uplink signal; or, when the parameters in the fourth synchronization signal indicate that the corresponding system is a TDD system, or when the first indication information does not configure the offset value and / or the frequency domain starting position, the terminal can consider that the frequency domain position of the fourth synchronization signal (e.g., the center frequency point) is the same as the frequency domain position of the second uplink signal, or consider that the frequency domain starting position of the second uplink signal is the frequency domain starting position of the fourth synchronization signal.

[0454] In practical applications, the frequency domain resources occupied by the second uplink signal can be a predefined value; or, the frequency domain resources occupied by the second uplink signal can be indicated by the first indication information. Specifically, one or more frequency domain resource values ​​occupied by the second uplink signal can be predefined, and one of the frequency domain resource values ​​can be indicated by the first indication information.

[0455] The time-domain configuration for the second uplink signal transmission timing may include one or more of the following:

[0456] The transmission timing of the second uplink signal is offset in the time domain compared to the transmission timing of the fourth synchronization signal;

[0457] Time-domain diagram of the transmission timing corresponding to the second uplink signal;

[0458] The second uplink signal occupies time domain resources.

[0459] In practical applications, one or more time-domain offset values ​​can be predefined (i.e., the offset value between the time-domain start position of the second uplink signal and the time-domain start position of the fourth synchronization signal), and one of the time-domain offset values ​​can be indicated by the first indication information. When the parameters in the fourth synchronization signal indicate that the corresponding system is an FDD system, or when the first indication information does not configure a time-domain offset value, the terminal can consider the time-domain start position of the fourth synchronization signal to be the time-domain start position of the second uplink signal, or in other words, the offset is 0.

[0460] In practical applications, one or more time-domain patterns for transmission opportunities can be predefined, and the time-domain pattern of one of the transmission opportunities can be indicated by the first indication information. When the parameters in the fourth synchronization signal indicate that the corresponding system is an FDD system, or when the first indication information does not configure a time-domain pattern, the terminal can assume that the transmission pattern of the fourth synchronization signal is the same as the transmission pattern of the second uplink signal.

[0461] In practical applications, the time-domain resources occupied by the second uplink signal can be predefined values; or, the frequency-domain resources occupied by the second uplink signal can be indicated by the first indication information. Specifically, one or more time-domain resource values ​​occupied by the second uplink signal can be predefined, and one of the time-domain resource values ​​can be indicated by the first indication information.

[0462] In practical applications, the terminal can determine the transmission sequence based on the first indication information, or it can determine the transmission sequence based on the first indication information and the index value of the fourth synchronization signal; wherein, the first indication information can be used to indicate the cell identifier, which is used to identify the cell corresponding to the terminal.

[0463] In practical applications, the transmit power corresponding to the second uplink signal is the maximum transmit power supported by the terminal; or, the minimum value between the maximum transmit power supported by the terminal and the first transmit power value; wherein, one or more first transmit powers are predefined, and one of the first transmit powers is indicated by the first indication information. Alternatively, the terminal can determine the transmit power of the second uplink signal using the transmit power of the fourth synchronization signal, the target receive power of the second uplink signal, and the path loss value; wherein, the path loss value can be determined by the terminal device based on the transmit power of the fourth synchronization signal; one or more fourth synchronization signals can be predefined, and the transmit power of one of the fourth synchronization signals can be indicated by the first indication information; one or more target receive powers can be predefined, and one of the target receive powers can be indicated by the first indication information.

[0464] In practical applications, the terminal can select any one of the four fourth synchronization signals with channel quality above a threshold, or the one with the best channel quality, the one with the lowest index, or all of the four fourth synchronization signals, and send a second uplink signal corresponding to the selected fourth synchronization signal. One or more thresholds can be predefined, and one of these thresholds can be indicated by a first indication information.

[0465] Step 1204: The terminal sends a second uplink signal based on the first information;

[0466] Step 1205: The network device receives the second uplink signal;

[0467] Step 1206: The network device sends a fifth synchronization signal corresponding to the second uplink signal;

[0468] Step 1207: The terminal receives the fifth synchronization signal.

[0469] The fifth synchronization signal may include configuration information of system information, such as frequency domain and / or time domain configuration of system information and / or scheduling control signals, such as starting position, occupied resources, etc.
