[0002] Reducing energy consumption and carbon dioxide emissions is one of the sustainable development goals of modern society. Wireless mobile communication networks usually deploy a large number of base stations, which are usually operated continuously for 24 hours, so a large amount of energy is consumed by the base stations of the mobile communication network every day. In order to reduce energy consumption and achieve a green communication network, an energy-saving mechanism is introduced in the wireless communication system, and an on-demand SSB is proposed. Currently, the base station periodically transmits SSBs, which results in unnecessary base station overhead and power consumption. SUMMARY

[0268] It should be understood that the phrase "one embodiment" or "an embodiment" throughout the specification means that a specific feature, structure, or characteristic related to the embodiment is included in at least one embodiment of this application. Therefore, "in one embodiment" or "in an embodiment" appearing throughout the specification does not necessarily refer to the same embodiment. Furthermore, these specific features, structures, or characteristics can be combined in any suitable manner in one or more embodiments.

[0269] In the various embodiments of this application, it should be understood that the sequence number of each process described below does not imply the order of execution. The execution order of each process should be determined by its function and internal logic, and should not constitute any limitation on the implementation process of the embodiments of this application.

[0270] In the embodiments of this application, the term "and / or" describes the relationship between associated objects, indicating that three relationships can exist. For example, A and / or B can represent three cases: A alone, A and B simultaneously, and B alone. The character " / " generally indicates that the preceding and following associated objects have an "or" relationship.

[0271] In the embodiments of this application, the term "multiple" refers to two or more, and other quantifiers are similar.

[0272] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0273] In describing the embodiments of this application, some concepts used in the following description will first be explained.

[0274] 1. On-demand SSB.

[0275] To conserve network energy, the concept of on-demand SSB was proposed. To reduce network power consumption, the secondary serving cell (SCell) can choose not to send SSBs or send traditional sparse SSBs (i.e., always-on SSBs). When a terminal requires an SSB, the SCell sends an on-demand SSB to meet the terminal's SSB needs. Figure 1 As shown, on-demand SSB activation may occur in the following four scenarios:

[0276] Scenario 1: During the period when the SCell is configured but the User Equipment (UE) has not received an activation command, the User Equipment (UE) can also be referred to as a terminal;

[0277] Scenario 2: When the terminal receives the SCell activation command;

[0278] Scenario 3: The period from when the terminal receives the SCell activation command until the SCell is fully activated;

[0279] Scenario 4: When SCell is fully activated.

[0280] II. Partial Bandwidth Part (BWP) Dormancy

[0281] Secondary serving cells (SCells) can be configured with dormant BWPs. If the active BWP of an active SCell is a dormant BWP, the terminal stops monitoring the transmission of the Physical downlink control channel (PDCCH), Random Access Channel (RACH), Sounding Reference Signal (SRS), Physical Uplink Shared Channel (PUSCH), and Physical Uplink Control Channel (PUCCH). However, if Channel State Information (CSI) measurement, Automatic Gain Control (AGC), and beam management are configured, the terminal will continue to perform CSI measurement, AGC, and beam management.

[0282] Embodiments of this application provide a method, apparatus, terminal, and network-side device for a terminal to request an SSB, in order to solve the problem of high power consumption caused by the periodic transmission of SSBs by the base station.

[0283] The method and apparatus are based on the same concept of the application. Since the methods and apparatus solve problems in similar ways, the implementation of the apparatus and methods can refer to each other, and the repeated parts will not be described again.

[0284] like Figure 2 As shown, an embodiment of this application provides a method for a terminal to request an SSB, applied to a terminal, specifically including the following steps:

[0285] Step 201: The terminal sends a first request message to the network-side device based on the mobility status and / or resource detection status. The first request message is used to request a synchronization signal block (SSB).

[0286] In this embodiment, the mobility state refers to the terminal's mobility speed, whether it is exceeding the speed limit, etc. The resource detection state refers to the result obtained by the terminal in detecting resources. The terminal can determine whether to request an SSB from the network-side device based on its own mobility state and / or the result of the resource detection. If an SSB request is required, the terminal sends a first request message to the network-side device, which instructs the network-side device to send an SSB. Optionally, the SSB can be an on-demand SSB.

[0287] In embodiments of this application, the terminal requests a Service Shield (SSB) from the network-side device based on its own mobility status and / or the results obtained from resource detection. This assists the network-side device in sending SSBs more accurately, thereby reducing the power consumption caused by the network-side device continuously sending SSBs.

[0288] Optionally, the movement state includes: whether the movement speed is greater than a first threshold.

[0289] In this embodiment, the first threshold can be a fixed value configured by the network-side device or predefined. The terminal determines its own movement speed. If the movement speed is greater than or equal to the first threshold, it requests an SSB from the network-side device; if its own movement speed is less than the first threshold, it does not need to request an SSB.

[0290] Optionally, the network-side device can also configure a movement speed range for the terminal. For example, a first speed range indicates a medium speed, and a second speed range indicates a high speed. The terminal determines its own movement speed and requests an SSB from the network-side device when moving at a medium or high speed. Alternatively, the movement speed range can be predefined, meaning the terminal itself can determine whether its current movement speed is low, medium, or high, and thus decide whether to request an SSB from the network-side device.

[0291] As an optional embodiment, the resource detection status includes one of the following:

[0292] 1) Among the measurement results of M measurements on N resources, there are A measurement results that are less than the second threshold, where N, M, and A are positive integers, and A is less than or equal to M;

[0293] The second threshold includes at least one of the following:

[0294] Pre-configured values;

[0295] Measurement results of reference resources;

[0296] The difference between the measurement result of the reference resource and a preset offset value, wherein the preset offset value is greater than or equal to 0.

[0297] In this embodiment, the N resources can be all or some of the resources already configured on the terminal. These resources can be configured on the network side or default to the originally configured SSBs; that is, the value of N can be configured or predefined by the network-side device. The number of measurements M can be configured or predefined by the network-side device as a fixed value, meaning it can be configured to measure some or all of the N resources once or multiple times.

[0298] Based on the obtained measurement results, if all M measurement results of N resources are less than the second threshold (where A equals M), or if some of the M measurement results of N resources are less than the second threshold (where A is less than M), then the terminal requests an SSB from the network-side device.

[0299] In this embodiment, N, M, A, and the second threshold can be configured by the network side or are fixed values. The second threshold can also be the measurement result of a reference resource or the difference between the measurement result of the reference resource and the offset value. The reference resource may be a preset resource (e.g., a sparse SSB), other transmitting SSBs, or other signal resources (e.g., CSI-RS), and is not limited here. The offset value can be a value configured or predefined by the network-side device.

[0300] 2) Within the first time frame, the measurement results of N resources are all less than the second threshold;

[0301] The second threshold includes at least one of the following:

[0302] Pre-configured values;

[0303] Measurement results of reference resources;

[0304] The difference between the measurement result of the reference resource and a preset offset value, wherein the preset offset value is greater than or equal to 0.

[0305] In this embodiment, the terminal measures N resources within a first time range. Each resource can be measured once or multiple times. When all the obtained measurement results are less than the second threshold, the terminal requests an SSB from the network-side device.

[0306] 3) Within the first time frame, among the measurement results of N resources, there are B measurement results that are less than the second threshold, where B is a positive integer;

[0307] The second threshold includes at least one of the following:

[0308] Pre-configured values;

[0309] Measurement results of reference resources;

[0310] The difference between the measurement result of the reference resource and a preset offset value, wherein the preset offset value is greater than or equal to 0.

[0311] In this embodiment, the terminal measures N resources within a first time range. Each resource can be measured once or multiple times. If B of the measured results are less than a second threshold, the terminal can request a Service Stub (SSB) from the network-side device. The first time range, the number of resources measured (N), and the number of measurement results used to determine the measurement results (B) can be configured or predefined by the network-side device.

[0312] As an optional embodiment, the first request message carries at least one of the following pieces of information:

[0313] 1) The function of the first request message; for example, it is used to request the network-side device to transmit on-demand SSB.

[0314] 2) The reason for initiating the first request message; for example, terminal movement, resource detection status meeting requirements, on-demand SSB request, etc.

[0315] 3) The SSB index corresponding to the reason for initiating the first request message; it can also be understood as the SSB index that caused the first request message, such as the index of the SSB with poor link quality in resource detection.

[0316] 4) The SSB resource set index corresponding to the reason for initiating the first request message; it can also be understood as the SSB resource set index that caused the first request message. A resource set index may contain one or more on-demand SSB indexes and / or one or more on-demand SSB resource configurations (such as period and / or frequency).

[0317] 5) The index of the requested SSB; for example, the SSB index of the on-demand SSB sent by the terminal to the network-side device.

[0318] 6) The index of the SSB resource set corresponding to the requested SSB; for example, the index of the SSB resource set of the on-demand SSB sent by the terminal requesting the network-side device.

[0319] 7) Requested beam identifier; for example, the terminal requests the network-side device to send the beam ID of the SSB.

[0320] 8) Indexes of other requested resources; for example, the terminal requests the indexes of other resources sent by the network-side device (e.g., CSI-RS index).

[0321] 9) The index of the top X SSB resource sets with the best measurement results, where X is a positive integer; it can be the index of the top X SSB resource sets with the best measurement results among the original SSB measurement results, where X is greater than or equal to 1, and can be configured by the network-side device or predefined as a fixed value.

[0322] 10) The index of the top Y SSBs with the best measurement results, where Y is a positive integer; it can be the index of the top Y SSBs with the best measurement results among the original SSBs, where Y is greater than or equal to 1, and can be configured by the network-side device or predefined as a fixed value.

[0323] 11) Measurement results: The measurement results corresponding to the resource detection status obtained by the terminal.

[0324] In this embodiment, the signaling when the terminal requests an SSB from the network-side device includes, but is not limited to, one or more of the above-mentioned items. The network-side device determines whether to send an SSB to the terminal based on the first request message.

[0325] Optionally, the signaling corresponding to the first request message sent by the terminal when requesting on-demand SSB from the network-side device includes, but is not limited to, at least one of the following:

[0326] Medium Access Control (MAC) Control Element (CE);

[0327] Uplink Control Information (UCI);

[0328] Radio Resource Control (RRC);

[0329] UE Assistance Information (UAI);

[0330] RACH;

[0331] PUSCH.

[0332] As an optional embodiment, the method further includes:

[0333] The first information sent by the monitoring network-side device includes at least one of the following:

[0334] (1) SSB; In this embodiment, after the terminal requests an on-demand SSB from the network-side device, it detects the SSB sent by the network-side device. Optionally, the terminal can wait for a period of time T1 and then listen for the on-demand SSB within time T. T1 is greater than or equal to 0. T1 and T can be configured or predefined by the network side.

[0335] Optionally, when the terminal sends the first request message to the network-side device, if the request message content contains the corresponding on-demand SSB, then the terminal listens for the on-demand SSB of the request.

[0336] (2) Acknowledgement (ACK): In this embodiment, after the terminal requests on-demand SSB from the network-side device, it detects the ACK feedback sent by the network-side device.

[0337] Optionally, after requesting an on-demand SSB, the terminal can wait for a period of time T1 and then listen for the ACK feedback of the first request message sent by the network-side device within time T. Optionally, the ACK feedback may contain other information, such as information about the on-demand SSB that is about to be transmitted (or activated). After detecting the ACK feedback from the network-side device, the terminal can start listening for the on-demand SSB after time T2. Optionally, if the ACK feedback contains other information, the terminal listens for the on-demand SSB based on the other information sent by the network-side device.

[0338] T1 and T2 are greater than or equal to 0, and T1, T2 and T can be configured or predefined by the network side.

[0339] (3) SSB transmission indication; optionally, the SSB transmission indication may be an SSB transmission (or activation) indication.

[0340] After the terminal requests an on-demand SSB from the network-side device, it detects the SSB transmission indication sent by the network-side device.

[0341] Optionally, after a terminal requests an on-demand SSB, it can wait for a period of time T1 and then listen for SSB transmission indications (or activation indications) sent by the network-side device within time T. The SSB transmission indication may contain at least one of the following information: the on-demand SSB configuration resource set index to be transmitted (or activated), the on-demand SSB index, the on-demand SSB configuration, and an indication of whether the on-demand SSB transmission (or activation) requested by the terminal is allowed.

[0342] Optionally, after the terminal detects the corresponding SSB transmission indication, it can listen for on-demand SSB after time T2. T1 and T2 are equal to or greater than 0. T1, T2 and T can be configured or predefined by the network side.

[0343] Optionally, for (1), (2), and (3) above, after the terminal requests on-demand SSB, it can listen for ACK feedback and SSB transmission indication sent by the network-side device. For example: after sending the request message, the terminal waits for a period of time T1 and then listens for ACK feedback from the network side regarding the terminal's request for on-demand SSB within time T; after monitoring the ACK feedback from the network side, the terminal starts listening for SSB transmission indication from the network side after time T2; after receiving the SSB transmission indication from the network side, it listens for on-demand SSB transmission within time T3. Time T1, T2, and T3 are greater than or equal to 0, and T1, T2, T3, and T can be configured or predefined by the network side.

[0344] (4) Rejection message: After the terminal requests on-demand SSB from the network-side device, it detects the rejection message sent by the network-side device.

[0345] Optionally, after the terminal requests on-demand SSB, it can wait for a period of time T1 and then listen for rejection feedback of the first request message sent by the network-side device within time T. Optionally, the rejection feedback may contain other information, such as the reason for rejection.

[0346] (5 Second time range, the second time range is the time range during which the terminal stops requesting SSB from the network-side device.)

[0347] In this embodiment, after the terminal requests an on-demand SSB from the network-side device, it detects the second time range sent by the network-side device. The network-side device indicates to the terminal the time range to stop requesting SSBs, and the terminal will not send request messages within that time range. Optionally, after sending the first request message, the terminal can wait for a period of time T1 and then listen to the second time range within time T. T1 is greater than or equal to 0, and T1 and T can be configured or predefined by the network side.

[0348] It should be noted that one or more of the above information can be sent by the network-side device through a single signaling message or through multiple signaling messages.

[0349] Optionally, the method further includes: when the network-side device does not indicate an SSB, listening to the SSB according to the default SSB resource configuration information.

[0350] In this embodiment, if there are multiple on-demand SSB resource configurations, the network-side device can pre-configure the default on-demand SSB. If the network-side device does not indicate the on-demand SSB to be transmitted (or activated), the terminal can listen according to the pre-configured default on-demand SSB resource configuration.

[0351] As an optional embodiment, the method further includes: performing a first operation;

[0352] The first operation includes at least one of the following:

[0353] 1) Change the index of the SSB for beam failure detection to the index of the requested SSB;

[0354] In this embodiment, after the terminal requests an SSB, the default SSB index for beam management is changed to the requested SSB index.

[0355] 2) Stop using the original SSB for beam failure detection and check for updated beam management configuration information sent by the network-side device; or, continue using the original SSB for beam failure detection and, upon receiving updated beam management configuration information sent by the network-side device, perform beam failure detection based on the updated beam management configuration information.

[0356] In this embodiment, after the terminal requests an SSB, it no longer performs beam management on the original SSB index. Instead, it waits for the network-side device to configure a new beam management configuration before using the new configuration information for beam management. Alternatively, after the terminal requests an on-demand SSB change, it continues to perform beam management on the original SSB index until it receives new configuration information from the network-side device, at which point it uses the new configuration information for beam management.

[0357] In this embodiment, after the terminal requests the SSB, it performs one or more of the beam management behaviors described above.

[0358] Optionally, when the terminal's active BWP is a dormant BWP, in order to ensure synchronization between the terminal and the SCell, the terminal is allowed to send an on-demand SSB request message (i.e., the first request message) to the network-side device. The signaling of the first request message includes, but is not limited to, at least one of the following:

[0359] PUCCH;

[0360] PUSCH;

[0361] RACH;

[0362] MAC CE;

[0363] RRC.

[0364] As an optional embodiment, the method further includes:

[0365] In the event of a monitoring failure, perform the second operation;

[0366] The second operation includes at least one of the following:

[0367] 1) Stop requesting SSB from the network-side device, or send a second request message to the network-side device, the second request message being used to request the SSB;

[0368] In this embodiment, after the terminal requests an on-demand SSB, some monitoring failures may occur. Upon a monitoring failure, the terminal can stop initiating on-demand SSB requests to the network-side device, i.e., it can cease sending request messages for the SSB; alternatively, the terminal can wait for a time d or immediately request the SSB again from the network-side device after the monitoring failure. For example, the terminal can wait for time d before requesting an on-demand SSB from the SCell, or the terminal can immediately request an on-demand SSB from the SCell.

[0369] 2) Send a third request message to the network-side device, the third request message being used to request the release or modification of secondary serving cell information.

[0370] In this embodiment, after the terminal requests an on-demand SSB, some monitoring failures may occur. Upon a monitoring failure, the terminal can request the network-side device to release or modify the secondary serving cell information. For example, after a monitoring failure, the terminal may send a message to the network-side device that the SCell is unavailable, requesting the release or modification of the SCell information.

[0371] Optionally, the monitoring failure includes at least one of the following:

[0372] 1) No first information is received from the network-side device within the third time range; wherein the third time range is configured or predefined by the network-side device.

[0373] Optionally, the first information includes at least one of the following:

[0374] SSB;

[0375] Affirmative response information;

[0376] SSB transmission indication;

[0377] Rejection information;

[0378] The second time range is the time range during which the terminal stops requesting SSB from the network-side device.

[0379] 2) The terminal requested SSB from the network-side device L times, but did not receive any SSBs, where L is a positive integer;

[0380] In this embodiment, after the terminal requests on-demand SSB, if any one or more of the above-mentioned monitoring failure behaviors occur, the second operation is executed.

[0381] For example: after a terminal requests an on-demand SSB, if the terminal does not receive an SSB transmission indication and / or ACK feedback from the network side within time T, the second operation described above is performed; or, after a terminal requests an on-demand SSB, if the terminal does not detect an on-demand SSB within time T (i.e., the third time range), the second operation described above is performed; or, after sending L on-demand SSB request messages, the terminal considers the on-demand SSB request to have failed, where L can be configured or predefined by the network-side device.

[0382] As an optional embodiment, the method further includes: receiving first configuration information sent by a network-side device; and determining the mobility state and / or the resource detection state based on the first configuration information.

[0383] The first configuration information includes at least one of the following:

[0384] a: The measurement resource used to determine the resource detection status; for example: N resources that the terminal needs to measure, or some of the N resources.

[0385] b: A threshold used to determine the resource detection status; for example, the second threshold may be a pre-configured value, or the measurement result of the reference resource, or the difference between the measurement result of the reference resource and a preset offset value.

[0386] c: A threshold used to determine the movement state; for example, a first threshold for the speed of movement of the terminal.

[0387] d: The number of resource measurements used to determine the resource detection status; for example, M measurements, A of the M measurement results, and B of the N resource measurement results.

[0388] e: The offset value used to determine the resource detection status; the terminal can determine the second threshold as the difference between the measurement result of the reference resource and the preset offset value based on this offset value.

[0389] f: The time range used to determine the resource detection status, such as the first time range, that is, the terminal can determine that the first time range is required when judging the resource detection status.

[0390] In this embodiment, the network-side device can configure conditions for the terminal to trigger an on-demand SSB request message, including but not limited to one or more of the above conditions. The terminal determines its mobility status and / or resource detection status based on the above conditions, thereby determining whether to request an SSB from the network-side device. Optionally, the network-side device can also configure a triggering event for the terminal to send the first request message, such as: the triggering event is that the terminal's mobility speed is greater than a first threshold, or the triggering event is that A out of M measurement results are less than a second threshold, etc.

[0391] As an optional embodiment, the method further includes:

[0392] Receive the second configuration information sent by the network-side device;

[0393] The information carried by the first request message is determined based on the second configuration information;

[0394] The second configuration information includes at least one of the following:

[0395] The first indication information is used to indicate whether the reason for initiating the first request message is carried;

[0396] The second indication information is used to indicate whether the SSB index corresponding to the reason for initiating the first request message is carried; for example, whether the SSB index that caused the request signaling is carried, i.e., the index of the SSB with poor link quality.

[0397] The third indication information is used to indicate whether the SSB resource set index corresponding to the reason for initiating the first request message is carried;

[0398] The fourth indication information is used to indicate whether the index of the SSB requested by the terminal is carried;

[0399] The fifth instruction information is used to indicate whether the index of the SSB resource set corresponding to the SSB requested by the terminal is carried;

[0400] The sixth indication information is used to indicate whether the beam identifier requested by the terminal is carried;

[0401] The seventh instruction information indicates whether to carry an index of other resources requested by the terminal; for example, whether to carry a CSI-RS index.

[0402] The eighth indication information is used to indicate whether to carry the indexes of the top X SSB resource sets with the highest measurement results, where X is a positive integer; for example, it indicates whether to carry the indexes of the top X SSB resource sets with the best original SSB measurement results, where X is greater than or equal to 1, and can be configured by the network-side device or predefined as a fixed value.

[0403] The ninth indication information is used to indicate whether to carry the indices of the top Y SSBs with the highest measurement results, where Y is a positive integer; for example, it indicates whether to carry the indexes of the top Y best SSBs with the best measurement results of the originally sent SSBs, where Y is greater than or equal to 1, and can be configured by the network side or predefined as a fixed value.

[0404] The tenth instruction is used to indicate whether the measurement results are carried.

[0405] In this embodiment, the network-side device can pre-configure the content of the on-demand SSB request message (i.e., the first request message) for the terminal, including one or more of the above-mentioned features. The terminal determines the content of the first request message based on the second configuration information described above.

[0406] The following example illustrates the implementation process of the terminal request SSB method in an embodiment of this application.

[0407] Example 1: Terminal in Figure 1The method for requesting SSB in Scenario 1 should be noted. Scenario 1 is only an example, and steps 11 to 15 of this example can be applied to other scenarios.

[0408] for Figure 1 Scenario 1: The terminal is constantly moving. As the terminal moves, it moves from beam N (which transmits SSB N) to beam M (which does not transmit SSB). For example, the terminal was originally within the coverage area of ​​beams 1 / 2 / 3 of the SCell, and the SSB transmission direction was also beams 1 / 2 / 3. SSBs in other beam directions were not transmitted. As the terminal moves, it gradually moves away from beams 1 / 2 / 3 and into the coverage area of ​​other beams, such as beams 4 / 5 / 6. In this case, the terminal can request on-demand SSBs in beams 4 / 5 / 6 from the network-side equipment so that it can continue to communicate with the SCell under beams with good channel quality.

[0409] The method includes:

[0410] Step 11: The terminal checks whether the conditions for an on-demand SSB request are met, and the conditions include, but are not limited to, one or more of the following:

[0411] a: The terminal detected that the measurement results of the original N resources were all less than a certain threshold M times. For example: the terminal detected that the measurement result R of SSB 1 was less than the threshold Th M times, where N and M are both equal to or greater than 1. N, M and Th can be configured by the network side or are fixed values. The resources monitored by the terminal can be configured by the network side or are the default SSBs transmitted in the original configuration.

[0412] b: The terminal detects that the measurement results of the original N resources are consistently less than the measurement results of other resources (e.g., sparse SSBs) for M consecutive times. For example, the terminal detects that the measurement result R1 of the original on-demand SSB1, after adding an offset, is still less than the measurement result R2 of the sparse SSB9 of the adjacent beam for M consecutive times. N and M can both be greater than or equal to 1, and N, M, and offset can be configured by the network side or be fixed values. The resources detected by the terminal can be configured by the network side or default to the SSBs transmitted in the original configuration.

[0413] c: Detects that the measurement results of N resources are all less than a threshold within a certain time period, or that B of the measurement results of N resources are less than the threshold. For example: The terminal detects that all measurement results of SSB1 within time T are less than the threshold, or that there are B measurements less than the threshold, where B is greater than or equal to 1. B and T can be configured by the network side or predefined.

[0414] Step 12: The terminal detects that the conditions for an on-demand SSB request are met and sends a request to the network-side device.

[0415] a: The signaling of the sent request message can be one or more of the following:

[0416] MAC CE;

[0417] UCI;

[0418] RRC;

[0419] UAI;

[0420] RACH;

[0421] PUSCH.

[0422] b: The content of the request message can be one or more of the following:

[0423] 1) The purpose of the request message is, for example, to request the base station to transmit on-demand SSB. It can be 1 bit information, requesting the network-side equipment to send on-demand SSB.

[0424] 2) Reason for initiation, such as: terminal movement or poor signal quality of the original resource. Optionally, this reason for initiation can indicate which number this initiation is.

[0425] 3) The SSB index that triggered the request message, such as the SSB index of poor link quality, so that the network-side device can decide whether to disable the on-demand SSB transmission based on the needs of the serving terminal. Optionally, if the on-demand SSB is only for this terminal, the network side can not transmit (or deactivate) the on-demand SSB transmission in order to save network-side energy consumption.

[0426] 4) The SSB resource set index that triggered the request signaling, such as the SSB resource set index with poor link quality, so that the network-side device can decide whether to close the on-demand SSB transmission based on the needs of the serving terminal.

[0427] 5) Request to send the SSB index of on-demand SSB. If the terminal detects sparse SSB resources in other directions or the measurement results of other resources are greater than a certain threshold or the conditions for triggering on-demand SSB are met, the terminal sends the requested SSB index to the network side so that the terminal can ensure good signal quality with SCell under the new beam.

[0428] 6) Request the sending of the SSB resource set index for on-demand SSB. If the terminal detects sparse SSB resources in other directions or the measurement results of other resources are greater than a certain threshold or the conditions for triggering on-demand SSB are met, the terminal sends the requested SSB resource set index to the network side so that the terminal can ensure good signal quality with the SCell under the new beam.

[0429] 7) Request the beam ID to be sent.

[0430] 8) Request other resource indexes (e.g., CSI-RS index).

[0431] 9) The top X SSB indices with the best measurement results from the original transmitting SSB, where X is greater than or equal to 1. X can be configured by the network side or be a fixed value. For example, the terminal reports the SSB index with the best measurement results in the detected transmitting SSB beam to the network side. The network side can infer the on-demand SSB that is about to be transmitted (or activated) based on the resource with the worst measurement results and the resource with the best measurement results.

[0432] 10) The index of the top N SSB resource sets with the best measurement results from the original SSB.

[0433] 11) Measurement results: When sending a request message, the terminal can carry the corresponding measurement results so that the network side can make a decision. For example, if the content of the request message sent by the terminal is the top X SSB indices with the best SSB measurement results sent in the original message, it can carry the measurement results corresponding to the SSB indices so that the network side can make a decision.

[0434] Optionally, after a terminal requests an on-demand SSB change, the corresponding beam management, such as beam failure detection operations, includes, but is not limited to, the following:

[0435] a) After the terminal requests an on-demand SSB change, the SSB index and / or SSB resource set index that are used for beam management by default will be changed to the requested SSB index and / or SSB resource set index. The original SSB index and / or SSB resource set index will no longer be used for beam management. Instead, the changed SSB index and / or SSB resource set index will be used until an RRC reconfiguration command is received.

[0436] b) After the terminal requests an on-demand SSB change, it will no longer perform beam management on the original SSB index and / or SSB resource set index, nor will it perform beam management on the changed SSB index and / or SSB resource set index. Instead, it will wait for the network side to configure a new beam management configuration.

[0437] c) After the terminal requests an on-demand SSB change, it continues to perform beam management on the original SSB index and / or SSB resource set index until it receives the new configuration from the network side.

[0438] Optionally, when the terminal's active BWP is a dormant BWP, in order to ensure synchronization between the terminal and the SCell, the terminal is allowed to send an on-demand SSB request message to the network side. The signaling of the request message can be one or more of the following:

[0439] PUCCH;

[0440] PUSCH;

[0441] RACH;

[0442] MAC CE.

[0443] Step 13: After the terminal requests an on-demand SSB, the corresponding monitoring behavior includes, but is not limited to, one or more of the following:

[0444] a: After the terminal requests on-demand SSB, it waits for a period of time T1 and then listens for on-demand SSB transmission within time T. T1 may be equal to 0 or greater than 0. T and T1 can be configured by the network side or be fixed values.

[0445] b: After the terminal requests an on-demand SSB, it waits for a period of time T1 and then listens for an ACK response to the on-demand SSB request within time T. Optionally, the ACK response may contain information about the on-demand SSB that will be transmitted (or activated). After receiving the ACK response from the network side, the terminal starts listening for the requested on-demand SSB after time T2, where T1 and T2 are greater than or equal to 0. For example: After sending a request message, the terminal waits for a period of time T1 and then listens for an ACK response within time T. This ACK may contain 1 bit of information to indicate that the network side has received the terminal's request message, and / or the ACK carries information about the on-demand SSB that will be transmitted (or activated). The terminal then listens for subsequent on-demand SSBs based on the ACK content.

[0446] c: After the terminal requests an on-demand SSB, it waits for a period of time T1 and then listens for an activation indication (or transmission indication) from the network side within time T. This activation indication (or transmission indication) can indicate whether the on-demand SSB requested by the terminal is allowed to be activated (or transmitted), for example, by indicating whether activation (or transmission) is allowed through 1-bit signaling; and / or, this activation indication (or transmission indication) can indicate the on-demand SSB configuration resource set index and / or on-demand SSB index and / or on-demand SSB configuration for activation (or transmission). After the terminal hears the corresponding activation indication (or transmission indication), it receives the on-demand SSB according to the corresponding on-demand SSB configuration after time T2, where T and T1 are equal to or greater than 0.

[0447] For example: After sending an on-demand SSB, the terminal waits for a period of time T1 and then listens for an activation indication (or transmission indication) within time T. If the activation indication (or transmission indication) is on-demand SSB resource set index1, the terminal listens for on-demand SSB index1 after time T2. Here, on-demand SSB resource set index1 may contain one or more on-demand SSB indices.

[0448] d: After the terminal requests on-demand SSB, it waits for a period of time T1 and then listens for ACK feedback and activation indication (or transmission indication) sent by the network side within time T. After receiving the ACK feedback from the network side, the terminal starts listening for the activation indication (or transmission indication) from the network side within time TT after time T2. After receiving the activation indication (or transmission indication) from the network side, the terminal listens for the transmission of on-demand SSB within time T3. Time T1, T2, and T3 are greater than or equal to 0.

[0449] e: If there are multiple on-demand SSB resource configurations, the network side can pre-configure a default on-demand SSB for the terminal. If the network side does not indicate which on-demand SSB will be activated (or transmitted), the terminal can listen according to the resource configuration of the default on-demand SSB.

[0450] Optionally, when the terminal sends a request message to the network-side device, if the content of the request message contains the corresponding on-demand SSB, the terminal listens for the requested on-demand SSB. For example, after sending an on-demand SSB request to the network-side device, the terminal directly listens for the requested on-demand SSB. If the network-side device does not indicate the on-demand SSB index and / or SSB resource set index and / or SSB resource set configuration that is about to be activated (or transmitted), the terminal can listen for the requested on-demand SSB resource configuration; after the terminal hears the ACK feedback or SSB transmission indication sent by the network-side device, it listens for the requested on-demand SSB.

[0451] Step 14: After the terminal requests on-demand SSB, the corresponding monitoring failure behavior includes, but is not limited to, one or more of the following:

[0452] a) The terminal does not receive an activation indication (or SSB transmission indication) and / or ACK feedback from the network side within time T. This time T can be configured by the network side or is a fixed value.

[0453] b) The terminal did not detect an on-demand SSB for the requested direction and / or the default direction within time T.

[0454] c) After sending L on-demand SSB requests, the terminal considers the on-demand SSB request to have failed. L can be equal to 0 or greater than 0, and can be configured by the network side or a predetermined value. For example, if the terminal fails to send an on-demand SSB request for the first time, waits for time T1 to send a second on-demand SSB request, and then waits for time T2 to send a third on-demand SSB request, and then fails again, the terminal considers the on-demand SSB request to have failed. T1 and T2 can be equal or unequal, and T1 and T2 can be configured by the network side or fixed values. The method for determining the failure of each on-demand SSB request is the same as in a) or b) of step 14 above. The values ​​of T1 and T2 are not limited here; they can be the same as or different from those in a) or b) of step 15.

[0455] Step 15: When the terminal requests on-demand SSB and monitoring fails, the terminal may perform one or more of the following actions:

[0456] a) The terminal waits for time 'a' before requesting the on-demand SSB to be sent to SCell. That is, after waiting for time 'a', steps 12 / 13 / 14 are repeated. 'a' can be configured by the network side or can be a fixed value.

[0457] b) The terminal continues to request the on-demand SSB from SCell, i.e., immediately repeat steps 12 / 13 / 14.

[0458] c) The terminal sends a message to the network side that the SCell is unavailable, requesting the release or modification of the SCell. For example, if step c) in step 17 occurs, the terminal sends a message to the network side that the SCell is unavailable.

[0459] d) The terminal no longer initiates on-demand SSB requests for the corresponding cell.

[0460] It should be noted that the embodiments of this application do not limit the execution order of the above steps, and the above steps are all optional execution steps, that is, the above steps can be executed independently or multiple steps can be combined for execution.

[0461] Example 2: Terminal in Figure 1 The network-side execution methods corresponding to the SSB request in Scenario 1 include:

[0462] Step 21: The network side pre-configures the triggering conditions for on-demand SSB and / or the content of the on-demand SSB request message for the terminal side.

[0463] a) The conditions under which the terminal triggers an on-demand SSB request include, but are not limited to, one or more of the following:

[0464] The terminal monitors resources used for on-demand SSB requests. For example, the network side configures the terminal to monitor SSB index, on-demand SSB resource set index, or other resource index for on-demand SSB requests. The terminal monitors these resources to determine whether to request the transmission of on-demand SSB.

[0465] The threshold conditions used by the terminal for on-demand SSB requests. For example: one or more of the following: threshold for comparing monitored resources, threshold for comparing adjacent resources and monitored resources, threshold for terminal movement speed, etc.

[0466] The comparison conditions used by the terminal for on-demand SSB requests. For example: the resources monitored by the terminal are all below the threshold M times, or the resources monitored by the terminal meet the trigger event of the on-demand SSB request M times, A of the M measurement results are all below the threshold, N of the measurement results are all below the threshold, B of the N of the measurement results are below the threshold, etc.

[0467] The time range used by the terminal for on-demand SSB requests, such as the first time range, that is, the terminal can determine that the first time range is a condition when judging the resource detection status.

[0468] The terminal uses this as a trigger event for on-demand SSB requests. For example, if the terminal detects that the measurement result R1 of the original on-demand SSB1, after adding an offset, is still less than the measurement result R2 of the sparse SSB9 of the adjacent beam, the network side can configure the terminal with the corresponding event ID and the corresponding offset value and / or other values ​​within the event.

[0469] b) The content of the request message from the network side to the terminal for pre-configuring on-demand SSB includes, but is not limited to, one or more of the following:

[0470] Whether to include the reason for initiation. If configured on the network side, the terminal side will include the corresponding reason for initiation when reporting.

[0471] Whether to carry the SSB index that caused the request signaling, i.e. the SSB with poor link quality. If configured on the network side, the terminal side will carry the original SSB index with poor signal quality when reporting.

[0472] Whether to carry the SSB resource set index that caused the request signaling. If configured on the network side, the terminal side will carry the SSB resource set index with poor original signal quality when reporting.

[0473] Whether to include the SSB index of the request sent to the on-demand SSB. If configured on the network side, the terminal side will include the requested SSB index when reporting.

[0474] Whether to include the SSB resource set index of the request sent to the on-demand SSB. If configured on the network side, the terminal side will include the requested SSB resource set index when reporting.

[0475] Whether to carry the beam ID of the request to be sent. If configured on the network side, the terminal side will carry the beam ID of the request when reporting.

[0476] Whether to include the index of other resources requested (e.g., CSI-RS index) when sending the request. If configured on the network side, the terminal side will include the requested resource index when reporting.

[0477] Whether to carry the indexes of the top X SSB resource sets with the best SSB measurement results sent originally, where X is greater than or equal to 1, can be configured by the network side or a fixed value.

[0478] Whether to carry the top Y best SSB indices of the original SSB measurement results, where Y is greater than or equal to 1, can be configured by the network side or be a fixed value.

[0479] Whether to carry measurement results so that the network side can make corresponding judgments.

[0480] Step 22: After the network side receives the on-demand SSB request message from the terminal side, the possible actions include, but are not limited to, one or more of the following:

[0481] 1) Upon receiving a request message from the terminal, the network-side device transmits an SSB. Optionally, the network-side device can transmit an SSB based on the terminal's request, decide which SSB to transmit itself, or transmit a default SSB. For example: if the terminal's request content includes the requested on-demand SSB index, the network side begins transmitting the corresponding on-demand SSB; or if the terminal's request content does not include the requested on-demand SSB index, the network side transmits the default SSB; or the network side decides which SSBs to transmit and transmits the corresponding SSBs.

[0482] 2) Upon receiving the request message from the terminal, the network side sends a corresponding ACK feedback to the terminal. For example, the network side sends the terminal a bit indicating whether the corresponding SSB activation is allowed, where 1 represents allowing activation of the on-demand SSB. After receiving this indication, if activation is allowed, the terminal listens for the requested or default on-demand SSB. Alternatively, the network side can also send information to the terminal indicating whether it has received the terminal's request message. Optionally, the ACK feedback may also include activated on-demand SSB information to indicate which on-demand SSB the terminal will subsequently listen for.

[0483] 3) After receiving the request message from the terminal, the network side sends a corresponding transmission instruction to the terminal. For example, the network side sends the corresponding on-demand SSB index and / or on-demand SSB resource set index and / or on-demand SSB configuration to the terminal. After receiving the instruction, the terminal confirms the SSB to be transmitted.

[0484] 4) The network side sends SSB configuration to the terminal. For example, the terminal requests the transmission of on-demand SSB1 and / or beam 1 and / or on-demand SSB resource set from the network side. The network side can instruct the terminal on the configuration of on-demand SSB1 (period, etc.); or the network side decides which SSBs to transmit and transmits the corresponding SSB configuration.

[0485] 5) The network side rejects the terminal's request and sends a corresponding rejection message to the terminal. Optionally, the rejection message may carry a reason for rejection, such as the beam's capacity being full. Optionally, the network side may indicate to the terminal other SSB indexes or SSB resource set indexes that can transmit on-demand SSBs. Optionally, the network side may indicate to the terminal the reason for changing the SSB, such as the requested SSB resource beam's capacity being full.

[0486] 6) The network side rejects the terminal's request based on reasons such as load and capacity, and does not send any signaling to the terminal.

[0487] 7) The network side indicates time T, indicating that the terminal is not allowed to initiate a request within time T. That is, after receiving this indication, the terminal will not initiate an on-demand SSB request within time T.

[0488] It should be noted that network-side devices can transmit the above information through one or more signaling messages. For example, the network-side device may first send an SSB transmission indication and / or ACK through one signaling message, which carries the SSB resource set index, and then send the SSB through another signaling message; or, the network side may send the SSB directly; or, the network-side device may send a rejection message and / or time T through one signaling message to notify the terminal to reject the terminal's SSB request and not allow the terminal to initiate a request within time T.

[0489] It should be noted that the embodiments of this application do not limit the execution order of the above steps, and the above steps are all optional execution steps, that is, the above steps can be executed independently or multiple steps can be combined for execution.

[0490] Example 3: The terminal is in Figure 1 The method for requesting SSB in Scenario 2 should be noted. Scenario 2 is only an example, and the content of this example can also be applied to other scenarios.

[0491] for Figure 1Scenario 2: For example, if the network does not transmit SSB or transmits sparse traditional SSB, and the terminal detects that the moving speed exceeds a certain threshold, the terminal sends auxiliary information to the network, which then decides whether to transmit (or activate) on-demand SSB. For instance, if the terminal's moving speed is high and the network transmits sparse SSB, the large measurement interval of the sparse SSB will lead to inaccurate reporting results. To obtain fast and accurate measurement results, after the terminal sends relevant auxiliary information, the network can decide whether to activate the transmission of some on-demand SSBs to obtain faster and more accurate measurement results.

[0492] The method includes:

[0493] Step 31: The terminal monitors the triggering conditions for the on-demand SSB request. The reasons why the terminal requests the on-demand SSB from the network side include, but are not limited to:

[0494] If the terminal's moving speed exceeds a certain threshold, which can be configured by the network side, the terminal can report this information when its moving speed exceeds the threshold. The network side then determines whether to send an on-demand SSB to meet measurement and synchronization requirements.

[0495] Step 32: The terminal requests an on-demand SSB from the network side. The request message is the same as in Example 1, and the content of the request message includes, but is not limited to, one or more of the following:

[0496] Reasons for initiation, such as the terminal's moving speed exceeding a threshold;

[0497] The direction of the terminal's movement, for example, after the terminal reports its direction of movement, the network side can infer the on-demand SSB that will be activated soon, so as to ensure the continuity of the terminal's movement process;

[0498] The rest of the content is the same as in Example 1, and will not be repeated here.

[0499] Steps 33 to 35 are the same as steps 13 to 15 in Example 1, and will not be repeated here.

[0500] It should be noted that the embodiments of this application do not limit the execution order of the above steps, and the above steps are all optional execution steps, that is, the above steps can be executed independently or multiple steps can be combined for execution.

[0501] In embodiments of this application, the terminal requests a Service Shield (SSB) from the network-side device based on its own mobility status and / or the results obtained from resource detection. This assists the network-side device in sending SSBs more accurately, thereby reducing the power consumption caused by the network-side device continuously sending SSBs.

[0502] likeFigure 3 As shown in the embodiments of this application, a method for a terminal to request an SSB is also provided, applied to a network-side device, including:

[0503] Step 301: The network-side device receives a first request message sent by the terminal, the first request message being used to request an SSB; wherein, the first request message is sent based on the terminal's mobility status and / or resource detection status.

[0504] In this embodiment, the mobility state refers to the terminal's mobility speed, whether it is exceeding the speed limit, etc. The resource detection state refers to the result obtained by the terminal in detecting resources. The terminal can determine whether to request an SSB from the network-side device based on its own mobility state and / or the result of the resource detection. If an SSB request is required, the terminal sends a first request message to the network-side device, which instructs the network-side device to send an SSB. Optionally, the SSB can be an on-demand SSB.

[0505] In embodiments of this application, the terminal requests a Service Stub (SSB) from the network-side device based on its own mobility status and / or the results obtained from resource detection. The network-side device can send SSBs more accurately based on the terminal's request, thereby reducing the power consumption caused by the network-side device continuously sending SSBs.

[0506] Optionally, the movement state includes: whether the movement speed is greater than a first threshold.

[0507] In this embodiment, the first threshold can be a fixed value configured by the network-side device or predefined. The terminal determines its own movement speed. If the movement speed is greater than or equal to the first threshold, it requests an SSB from the network-side device; if its own movement speed is less than the first threshold, it does not need to request an SSB.

[0508] Optionally, the network-side device can also configure a movement speed range for the terminal. For example, a first speed range indicates a medium speed, and a second speed range indicates a high speed. The terminal determines its own movement speed and requests an SSB from the network-side device when moving at a medium or high speed. Alternatively, the movement speed range can be predefined, meaning the terminal itself can determine whether its current movement speed is low, medium, or high, and thus decide whether to request an SSB from the network-side device.

[0509] As an optional embodiment, the resource detection status includes one of the following:

[0510] 1) Among the measurement results of M measurements on N resources, there are A measurement results that are less than the second threshold, where N, M, and A are positive integers, and A is less than or equal to M;

[0511] The second threshold includes at least one of the following:

[0512] Pre-configured values;

[0513] Measurement results of reference resources;

[0514] The difference between the measurement result of the reference resource and a preset offset value, wherein the preset offset value is greater than or equal to 0.

[0515] In this embodiment, the N resources can be all or some of the resources already configured on the terminal. These resources can be configured on the network side or default to the originally configured SSBs; that is, the value of N can be configured or predefined by the network-side device. The number of measurements M can be configured or predefined by the network-side device as a fixed value, meaning it can be configured to measure some or all of the N resources once or multiple times.

[0516] Based on the obtained measurement results, if all M measurement results of N resources are less than the second threshold (where A equals M), or if some of the M measurement results of N resources are less than the second threshold (where A is less than M), then the terminal requests an SSB from the network-side device.

[0517] In this embodiment, N, M, A, and the second threshold can be configured by the network side or are fixed values. The second threshold can also be the measurement result of a reference resource or the difference between the measurement result of the reference resource and the offset value. The reference resource may be a preset resource (e.g., a sparse SSB), other transmitting SSBs, or other signal resources (e.g., CSI-RS), and is not limited here. The offset value can be a value configured or predefined by the network-side device.

[0518] 2) Within the first time frame, the measurement results of N resources are all less than the second threshold;

[0519] In this embodiment, the terminal measures N resources within a first time range. Each resource can be measured once or multiple times. When all the obtained measurement results are less than the second threshold, the terminal requests an SSB from the network-side device.

[0520] 3) Within the first time frame, among the measurement results of N resources, there are B measurement results that are less than the second threshold, where B is a positive integer;

[0521] The second threshold includes at least one of the following:

[0522] Pre-configured values;

[0523] Measurement results of reference resources;

[0524] The difference between the measurement result of the reference resource and a preset offset value, wherein the preset offset value is greater than or equal to 0.

[0525] In this embodiment, the terminal measures N resources within a first time range. Each resource can be measured once or multiple times. If B of the measured results are less than a second threshold, the terminal can request a Service Stub (SSB) from the network-side device. The first time range, the number of resources measured (N), and the number of measurement results used to determine the measurement results (B) can be configured or predefined by the network-side device.

[0526] Optionally, the first request message carries at least one of the following pieces of information:

[0527] The purpose of the first request message;

[0528] The reason for initiating the first request message;

[0529] The SSB index corresponding to the reason for initiating the first request message;

[0530] The SSB resource set index corresponding to the reason for initiating the first request message;

[0531] The index of the requested SSB;

[0532] The index of the SSB resource set corresponding to the requested SSB;

[0533] The requested beam identifier;

[0534] Indexes of other requested resources;

[0535] The indices of the top X SSB resource sets with the best measurement results, where X is a positive integer;

[0536] The indices of the top Y SSBs with the best measurement results, where Y is a positive integer;

[0537] Measurement results.

[0538] In this embodiment, the signaling when the terminal requests an SSB from the network-side device includes, but is not limited to, one or more of the above-mentioned items. The network-side device determines whether to send an SSB to the terminal based on the first request message.

[0539] As an optional embodiment, the method further includes:

[0542] A positive response is provided; after the terminal requests an on-demand SSB from the network-side device, the network-side device can send an ACK feedback to the terminal, and then send an on-demand SSB after a period of time. Optionally, this ACK feedback may contain other information, such as information about the on-demand SSB that will be activated soon.

[0543] SSB transmission indication; the SSB transmission indication may be an SSB activation indication. After the terminal requests an on-demand SSB from the network-side device, the network-side device may send an SSB transmission indication to the terminal; optionally, the network-side device may send an on-demand SSB after a period of time.

[0544] Rejection message: After the terminal requests an on-demand SSB from the network-side device, the network-side device may refuse to send an SSB to the terminal, in which case a rejection message will be sent.

[0545] The second time range is the period during which the terminal stops requesting SSBs from the network-side device. After the terminal requests an on-demand SSB from the network-side device, the network-side device indicates to the terminal the time range during which it will stop requesting SSBs, and the terminal will not send request messages within that time range.

[0546] Optionally, when the network-side device sends the above information to the terminal, one or more of the above information can be sent by the network-side device through one signaling message or through multiple signaling messages.

The terminal determines its mobility status and / or resource detection status based on the above conditions, thereby determining whether to request an SSB from the network-side device. Optionally, the network-side device can also configure a triggering event for the terminal to send the first request message, such as: the triggering event is that the terminal's mobility speed is greater than a first threshold, or the triggering event is that A out of M measurement results are less than a second threshold, etc.

[0562] As an optional embodiment, the method further includes:

[0575] In this embodiment, the network-side device can pre-configure the content of the on-demand SSB request message (i.e., the first request message) for the terminal, including one or more of the above-mentioned features. The terminal determines the content of the first request message based on the second configuration information described above.

[0576] In embodiments of this application, the terminal requests a Service Stub (SSB) from the network-side device based on its own mobility status and / or the results obtained from resource detection. The network-side device can send SSBs more accurately based on the terminal's request, thereby reducing the power consumption caused by the network-side device continuously sending SSBs.
