Description

SSB transmission methods, devices, terminals and equipment

[0001] This disclosure claims priority to Chinese Patent Application No. 202410855604.8, filed with the Chinese Patent Office on June 28, 2024, entitled "Transmission Method, Apparatus, Terminal and Device for SSB", the entire contents of which are incorporated herein by reference. Technical Field

[0002] This disclosure relates to the field of communication technology, and in particular to a method, apparatus, terminal and device for transmitting SSB. Background Technology

[0003] Reducing energy consumption and carbon dioxide emissions is one of the sustainable development goals of modern society. Wireless mobile communication networks typically deploy a large number of base stations, which usually transmit Synchronization Signal Blocks (SSBs) 24 / 7, consuming a significant amount of energy daily. To reduce energy consumption and achieve green communication networks, energy-saving mechanisms have been introduced into wireless communication systems. For connected terminals, the secondary serving cell (Scell) transmits SSBs only when needed; otherwise, the Scell ​​either doesn't transmit SSBs or transmits only sparse ones. This method effectively saves power. However, for on-demand SSBs, the terminal cannot know the network's information about the transmitted SSBs, potentially leading to unnecessary or erroneous signaling processes and failing to reduce energy consumption. Summary of the Invention

[0205] It should be understood that the phrase "an embodiment" or "one embodiment" throughout the specification means that a particular feature, structure, or characteristic relating to an embodiment is included in at least one embodiment of this disclosure. Therefore, "in one embodiment" or "one embodiment" appearing throughout the specification does not necessarily refer to the same embodiment.

[0206] In the various embodiments of this disclosure, 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 disclosure.

[0207] In this disclosure, the term "and / or" describes the relationship between related 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 related objects have an "or" relationship.

[0208] In this disclosure, the term "multiple" refers to two or more, and other quantifiers are similar.

[0209] The technical solutions of the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this disclosure, and not all embodiments. Based on the embodiments of this disclosure, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this disclosure.

[0210] In describing the embodiments of this disclosure, some concepts used in the following description will first be explained.

[0211] 1. On-demand SSB.

[0212] To conserve network-side energy, the concept of on-demand SSB is proposed. To reduce network-side power consumption, the SCell can choose not to send an SSB or send a traditional sparse SSB (i.e., always-on SSB). When the terminal requires an SSB, the SCell sends an on-demand SSB to meet the terminal's SSB needs. As shown in Figure 1, on-demand SSB activation may occur in the following four scenarios:

[0213] Scenario 1: SCell is configured but the terminal has not received the activation command;

[0214] Scenario 2: When the terminal receives the SCell activation command;

[0215] Scenario 3: The period from when the terminal receives the SCell activation command until the SCell is fully activated;

[0216] Scenario 4: When SCell is fully activated.

[0217] II. SCell Configuration.

[0218] For terminals supporting Carrier Aggregation (CA), one or more SCells can be aggregated with Special Cells (SpCells) to expand bandwidth. Currently, each terminal can be configured with a maximum of two cell groups. Each cell group can be configured with a maximum of 32 serving cells, including one primary serving cell (Pcell) and 31 SCells. The network side can add / modify / delete SCells for the terminal according to its needs via Radio Resource Control (RRC) ConnectionReconfiguration messages. SCells are not necessarily activated immediately after configuration; their status settings include the following:

[0219] When adding a SCell, if the SCellState is set to the activated state in the RRCConnectionReconfiguration message, the SCell will be activated during configuration; otherwise, the SCell will be deactivated.

[0220] After adding a SCell, the network side can activate / deactivate the Medium Access Control (MAC) Control Element (CE) via the SCell, or enhance the SCell activation / deactivation MAC CE to activate or deactivate the SCell.

[0221] Each SCell corresponds to a timer (sCellDeactivationTimer), and the SCell is deactivated when the timer expires;

[0222] When the terminal receives the Secondary Cell Group State (scg-State), the entire Secondary Cell Group (SCG) is in an inactive state, meaning that the SCells under that SCG are also inactive.

[0223] III. BWP Configuration.

[0224] The bandwidth can be adjusted according to the terminal's needs. Terminals with high transmission rates can be configured with a large bandwidth, while terminals with lower transmission rate requirements can be configured with a narrow bandwidth. For connected terminals, up to four BWPs can be configured for the uplink (UL) / downlink (DL). Additionally, there is one initial BWP that can be used for SCell activation. Therefore, the terminal needs to store a maximum of five DL / UL BWP configurations. However, at any given time, only one BWP can be active. The terminal can switch between different BWPs to meet different needs. DL BWP switching methods include:

[0225] a) Switch the BWP by reconfiguring the initial active downlink BWP identifier (firstActiveDownlinkBWP-Id) via the RRCConnectionReconfiguration message;

[0226] b) Based on the configured inactivity timer of the BWP, when the bwp-inactivityTimer times out, return from the currently active BWP to the default BWP.

[0227] c) Switching via Downlink Control Information (DCI).

[0228] Dormant BWP: If the BWP is configured as a dormant BWP, the terminal will stop monitoring the transmission of the Physical downlink control channel (PDCCH) and the Random Access Channel (RACH), Sounding Reference Signal (SRS), Physical Uplink Shared Channel (PUSCH), and Physical Uplink Control Channel (PUCCH), but will continue to perform Channel State Information (CSI) measurement, Automatic Gain Control (AGC), and beam management (if configured).

[0229] Default BWP: The network side can configure a default BWP for the terminal. If not configured, the initial BWP can be assumed to be the default BWP. When the BWP timer expires, the terminal will switch back to the default BWP.

[0230] The embodiments of this disclosure provide a method, apparatus, terminal, and device for transmitting SSB, in order to solve the problem of high transmission power consumption.

[0231] 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.

[0232] As shown in Figure 2, an embodiment of this disclosure provides an SSB transmission method applied to a terminal, specifically including the following steps:

[0233] Step 201: The terminal receives the first information sent by the network-side device, the first information being used to indicate the transmission of the synchronization signal block (SSB);

[0234] The first information includes at least one of the following:

[0235] The identifier of the target BWP corresponding to the partial bandwidth BWP switch; the target BWP refers to the BWP to which the user is to switch.

[0236] The purpose of the SSB; it can also be understood as the scope of application of the SSB; in some embodiments, it can be the purpose of the activated or transmitted SSB;

[0237] The index of the SSB resource collection;

[0238] SSB index.

[0239] In this embodiment, the network-side device sends first information to the terminal to indicate SSB transmission. The terminal can determine the transmitted SSB based on this first information, and / or determine how to use the SSB in subsequent measurements or beam failure detection, and / or determine the activated SSB, and / or determine the deactivated SSB, thereby avoiding unnecessary signaling processes and terminal behavior. The SSB can be an on-demand SSB. In some embodiments, the first information is used to indicate SSB transmission, but can also be understood as indicating SSB activation and / or deactivation.

[0240] In some embodiments, multiple pieces of information in the first information are sent by the network-side device via a single signaling signal, or via multiple separate signaling signals.

[0241] In this embodiment, for one or more of the aforementioned first information, the network-side device can send multiple pieces of first information simultaneously through a single signaling instruction, or it can send each piece of first information separately through multiple signaling instructions. For example, the network-side device can simultaneously send the SSB index, the SSB's purpose, and the identifier of the target BWP corresponding to the BWP handover through a single signaling instruction; or, the network-side device can send the SSB index through signaling instruction 1, the SSB's purpose through signaling instruction 2, and the identifier of the target BWP corresponding to the BWP handover through signaling instruction 3. This embodiment does not limit the method by which the network-side device sends the first information.

[0242] In embodiments of this disclosure, the network-side device sends first information to the terminal to indicate SSB transmission, such as the identifier of the target BWP corresponding to the BWP switching, the purpose of the SSB, the index of the SSB resource set, and one or more of the SSB indexes. Based on this first information, the terminal can accurately determine the SSB transmitted by the network-side device, avoiding unnecessary signaling processes and terminal actions, effectively reducing transmission power consumption and improving transmission efficiency.

[0243] In some embodiments, the first information has a corresponding relationship with the indication function of the first information; the corresponding relationship includes at least one of the following:

[0244] (1) If the first information includes: a first index of the SSB resource set and / or a second index of the SSB; then the first information is used to indicate: to transmit (or activate) the SSB corresponding to the first index and / or to transmit (or activate) the SSB corresponding to the second index, and not to transmit (or deactivate) the SSB resource set that has been transmitted (or activated) and / or the SSB that has been transmitted (or activated).

[0245] In this embodiment, if the network-side device indicates the index of the SSB resource set and / or the index of the SSB, it is considered that the resource set index and / or the on-demand SSB index indicates the transmission (or activation), and the resource set and / or the on-demand SSB index of the transmitted (or activated) on-demand SSB are not transmitted (or deactivated). In this case, the signaling content sent by the network-side device is the on-demand SSB resource set index and / or the on-demand SSB index.

[0246] (2) If the first information includes: a first index of the SSB resource set and / or a second index of the SSB; then the first information is used to indicate: to transmit (or activate) the SSB corresponding to the first index and / or to transmit (or activate) the SSB corresponding to the second index, and the state of the SSB resource set and / or the SSB that has been transmitted (or activated) remains unchanged.

[0247] In this embodiment, if the network-side device indicates the index of the SSB resource set and / or the index of the SSB, it is considered that the resource set index and / or on-demand SSB index indicating transmission (or activation) are activated. The already transmitted (or activated) on-demand SSB resource set configuration and / or on-demand SSB index are not deactivated, i.e., transmission continues. In this case, the signaling content sent by the network-side device is the on-demand SSB resource set index and / or on-demand SSB index.

[0248] (3) If the first information includes: a first index of the SSB resource set and / or a second index of the SSB, and the first information also includes the status information of the SSB resource set that has been transmitted (or activated) and / or the SSB that has been transmitted (or activated); then the first information is used to indicate: to transmit (or activate) the SSB corresponding to the first index and / or to transmit (or activate) the SSB corresponding to the second index, and to adjust or not adjust the status of the SSB resource set that has been transmitted (or activated) and / or the SSB that has been transmitted (or activated) according to the status information;

[0249] In this embodiment, if the network-side device indicates the index of the SSB resource set and / or the index of the SSB, and indicates the state of the SSB resource set and / or the SSB that has been transmitted (or activated), the terminal can determine whether to deactivate the transmitted (or activated) SSB based on the indicated state. For example: if the network-side device indicates that the resource set of the transmitted (or activated) on-demand SSB and / or the state of the on-demand SSB is transmitted, such as {activated}, then the resource set of the transmitted (or activated) SSB and / or the state of the SSB remains unchanged; if the network-side device indicates that the resource set of the transmitted (or activated) on-demand SSB and / or the state of the on-demand SSB is not transmitted (or deactivated), such as {deactivated}, then it means that the resource set of the transmitted (or activated) on-demand SSB and / or the on-demand SSB will not be transmitted (or deactivated).

[0250] (4) If the first information includes: transmitting (or activating) list 1 and / or not transmitting (or deactivating) list 2, then the first information is used to indicate: transmitting (or activating) the SSB resource set and / or SSB contained in list 1; and / or deactivating the SSB resource set and / or SSB in list 2.

[0251] In this embodiment, the network-side device can indicate the activation or deactivation status of the on-demand SSB resource set index and / or the on-demand SSB index. For example, if the content of the first information sent by the network-side device is the transmitted (or activated) on-demand SSB resource set index and / or the on-demand SSB index and / or the non-transmitted (or deactivated) on-demand SSB resource set index and / or the on-demand SSB index, then the terminal can directly determine which SSBs are transmitted (or activated) and which SSBs are not transmitted (or deactivated).

[0252] (5) If the first information includes bitmap information, and each bit of the bitmap information corresponds to an SSB resource set and / or an SSB, then the first information is used to indicate: the state of the SSB resource set and / or the SSB is determined according to the value of the bitmap information.

[0253] In this embodiment, the network-side device can indicate the first information in the form of a Bitmap, for example, by indicating the transmission status of the on-demand SSB resource set index and / or the on-demand SSB index in the form of a Bitmap.

[0254] (6) If the first information includes: a first index of the SSB resource set and / or a second index of the SSB; then the first information is used to indicate: to transmit the SSB corresponding to the first index and / or to transmit the SSB corresponding to the second index.

[0255] In this embodiment, if the network-side device indicates the on-demand SSB resource set index and / or the on-demand SSB index, it can be assumed that this indication only defines the on-demand SSB transmission behavior for this time, without considering previous on-demand SSB transmissions.

[0256] (7) If the first information includes: the resource set index and SSB index of the transmitted (or activated) on-demand SSB, it means that the SSB is transmitted with the configuration in the corresponding SSB resource set index. For example, if the first information includes SSB 1 and SSB resource set 1, it means that SSB1 is transmitted with the configuration of the SSB resource set, such as period, frequency, etc.

[0257] As an optional embodiment, the method further includes: receiving configuration information of an SSB resource set sent by a network-side device, wherein the configuration information of the SSB resource set includes at least one of the following:

[0258] 1) Index of SSB resource set; The network-side device can pre-configure one or more indexes of SSB resource sets, and can subsequently send the index of a certain SSB resource set to the terminal to indicate whether to activate or deactivate the SSB resource set corresponding to that index.

[0259] 2) SSB Index; The network-side device can configure one or more SSB indexes in the SSB resource set. Subsequently, it can send the index of a certain SSB resource set to the terminal, and then the SSB index will be transmitted.

[0260] 3) Duration of SSB transmission; the duration for which the index of the SSB resource set and / or the index of the SSB configured by the network-side device will no longer be transmitted after the specified duration.

[0261] 4) SSB transmission period; By pre-configuring the SSB transmission period, the terminal can transmit based on the pre-configured period when transmitting SSBs in subsequent transmissions.

[0262] 5) SSB PositionsInBurst: By configuring the transmission position of the SSB, the transmission of the SSB is indicated.

[0263] 6) SSB transmission frequency; By pre-configuring the SSB transmission frequency, the terminal can transmit based on the pre-configured frequency when transmitting SSB in subsequent transmissions.

[0264] In this embodiment, the network-side device can pre-configure SSB resource sets and their configuration information for the terminal. For example, it can pre-configure one or more SSB resource set indexes, one or more SSB indexes, and one or more information such as SSB transmission duration, transmission period, transmission frequency, and transmission bitmap. By pre-configuring the SSB resource set configuration information, the terminal can subsequently be shown the indexes of active or deactivated SSB resource sets and / or SSB indexes, and the terminal can learn about the transmitted SSBs based on the pre-configured information.

[0265] In some embodiments, the method further includes:

[0266] If the first information includes a first index of an SSB resource set and / or a second index of an SSB, then it is determined that the SSB resource set corresponding to the first index and / or the SSB corresponding to the second index are transmitted.

[0267] or,

[0268] If the first information includes a first index of the SSB resource set and a second index of the SSB, then the configuration information of the SSB corresponding to the second index has been transmitted in the SSB resource set corresponding to the first index, and it can be determined that the second index under the SSB resource set corresponding to the first index has been transmitted.

[0269] In this embodiment, if the terminal receives a first index of the SSB resource set and / or a second index of the SSB indicated by the network-side device, it means that the SSB corresponding to the first index is transmitted and / or the SSB corresponding to the second index is transmitted. Alternatively, if the terminal receives a first index of the SSB resource set and a second index of the SSB sent on demand, it means that the configuration of the SSB resource set corresponding to the first index includes the configuration of the SSB corresponding to the second index. For example, the network-side device transmits the SSB configuration information in the pre-configured SSB resource set configuration information, and the network side indicates the SSB index through the first information, then the SSB index under the SSB resource set corresponding to the first index is transmitted.

[0270] As an optional embodiment, the first information is also used to indicate BWP switching;

[0271] The method further includes:

[0272] Receive configuration information sent by the network-side device, the configuration information including: BWP configuration information and / or SSB pre-configuration information;

[0273] If the target BWP for the BWP switch is the default BWP, the SSB corresponding to the target BWP is received according to the pre-configuration information and / or the configuration information of the SSB before the switchover.

[0274] In this embodiment, the first information can also indicate BWP switching. For example, when the network-side device indicates the transmission (or activation) of a certain on-demand SSB, if there is a simultaneous BWP switching, it can send an SSB transmission (or activation) indication to the terminal. This indication includes the transmitted (or activated) SSB index and / or SSB resource set index, as well as the identifier of the target BWP corresponding to the BWP switching. That is, when the network-side device indicates the transmission (or activation) of the on-demand SSB, it indicates the BWP ID to be switched. Alternatively, when the network-side device indicates BWP switching, it indicates the activated on-demand SSB. It should be noted that the network-side device can indicate the SSB index and / or SSB resource set index and / or BWP ID through one or more signaling messages.

[0275] Network-side devices can pre-configure SSB-related information when configuring a BWP for a terminal, such as SSB transmission period, frequency, and SSB-PositionsInBurst. When a terminal performs a BWP handover to a default BWP (and / or dormant BWP), if some SSB information was configured during BWP pre-configuration, the corresponding on-demand SSB configuration can be changed to the configuration used during BWP pre-configuration. That is, the terminal can determine the relevant SSB parameters after the BWP handover based on the pre-configured SSB parameters, such as transmission period, frequency, and location, and can then use these pre-configured parameters to receive the SSB. If the network-side device has not pre-configured some SSB information, the terminal can determine the relevant SSB parameters after the BWP handover based on the SSB configuration before the handover, such as transmission period, frequency, and location, and can then reuse the on-demand SSB configuration from before the handover to receive the SSB.

[0276] For example, for the default BWP, the corresponding SSBs may be pre-configured during BWP pre-configuration. If switching to the default BWP, the corresponding SSBs will change according to the pre-configuration. If some SSB configurations (such as transmission direction) are not configured in the pre-configuration, the previous (before switching to default) BWP SSB configurations will be reused.

[0277] In some embodiments, when a BWP handover occurs, the first information further includes: the SSB transmission period after the BWP handover. In this embodiment, when a BWP handover occurs, the network-side device can indicate the on-demand SSB period after the handover at the same time as indicating the BWP handover. For example, when the network-side device instructs the terminal to switch to a dormant BWP, it can simultaneously indicate the on-demand SSB period after the handover.

[0278] In some embodiments, for a dormant BWP, when the network-side device instructs the terminal to switch to a dormant BWP, it may simultaneously instruct the on-demand SSB resource set index or the on-demand SSB index after the switch. This can also be understood as the network-side device instructing the first information to be the index of the SSB resource set and / or the index of the SSB, and instructing the BWP switch, and the instructing index of the SSB resource set and / or the index of the SSB is applied after the BWP switch.

[0279] As an optional embodiment, the SSB may be used for at least one of the following purposes:

[0280] 1) L1 measurement; that is, the network-side device indicates to the terminal that the purpose of the SSB is L1 measurement. For example, if the network-side device sends the SSB index to the terminal and the purpose of the SSB is L1 measurement, it means that the SSB corresponding to the indicated SSB index is used for L1 measurement and / or L1 measurement reporting.

[0281] 2) L3 measurement; that is, the network-side device indicates to the terminal that the purpose of the SSB is L3 measurement. For example, if the network-side device sends the SSB index to the terminal and states that the purpose of the SSB is L3 measurement, it means that the SSB corresponding to the indicated SSB index is used for L3 measurement and / or L3 measurement reporting. In some embodiments, the L3 measurement is a measurement obtained from the RRC layer.

[0282] 3) Beam failure detection, whereby the network-side device indicates to the terminal that the purpose of the SSB is beam failure detection. For example, the network-side device sends the SSB index and the purpose of the SSB to the terminal, indicating that the SSB corresponding to the indicated SSB index is used for beam failure detection. In this embodiment, the network-side device can indicate whether beam failure detection should be performed through a new signaling. For example, beam failure detection was previously configured, but because no SSB was being transmitted (on-demand SSB means that no SSB was being transmitted previously or the transmission was sparse, and it is transmitted only when needed), the terminal will not perform beam failure detection. When on-demand SSB is being transmitted, the network-side device can indicate to the terminal whether beam failure detection is required.

[0283] In some embodiments, where the purpose of the SSB is L1 measurement, the SSB is used to trigger at least one of the following operations in the L1 measurement:

[0284] Perform L1 measurements; for example, the SSB indicated by the network-side device is used to perform L1 measurements.

[0285] L1 measurement configuration update; for example, the SSB indicated by the network-side device is used to perform L1 measurement configuration update; for example, before the terminal receives the SSB or receives the purpose of the SSB sent by the network-side device, L1 measurement is not performed. After receiving the purpose of the SSB indicated by the network side, the terminal updates the L1 measurement configuration according to the L1 measurement configuration information pre-configured by the network side and performs L1 measurement.

[0286] L1 measurement report; in this case, it is assumed that the network-side device triggers the terminal's L1 measurement report by indicating the first information.

[0287] And / or, if the purpose of the SSB is L3 measurement, the SSB is used to trigger at least one of the following operations in the L3 measurement:

[0288] Perform L3 measurements; for example, the SSB indicated by the network-side device is used to perform L3 measurements.

[0289] L3 measurement configuration update; for example, the SSB indicated by the network-side device is used to perform L3 measurement configuration update; for example, before the terminal receives the SSB or receives the purpose of the SSB sent by the network-side device, L3 measurement is not performed. After receiving the purpose of the SSB indicated by the network side, the terminal updates the L3 measurement configuration according to the L3 measurement configuration information pre-configured by the network side and performs L3 measurement.

[0290] In the case of an L3 measurement report, it is assumed that the network-side device triggers the terminal's L3 measurement report by indicating the first information.

[0291] In some embodiments, when the first information includes the purpose of the SSB, it can be indicated in the form of a bitmap, for example, 001 represents BFD being active and L1 / L3 measurement being inactive. Alternatively, the purpose of the SSB can be indicated by an index, for example, 00 represents BFD, 01 represents L1 measurement, 10 represents L3 measurement, etc. The method by which the network-side device indicates the purpose of the SSB is not limited here.

[0292] As an optional embodiment, the method further includes:

[0293] The L3 measurement report is triggered if the first condition is met.

[0294] The first condition includes at least one of the following:

[0295] 1) The secondary serving cell for transmitting SSB is an unknown cell;

[0296] 2) Obtain the measurement results of the secondary serving cell transmitting the SSB based on the first information; that is, after receiving the first information, the terminal obtains new measurement results based on the first information.

[0297] 3) The time interval between the current time and the last reported measurement result of the secondary serving cell is greater than the first threshold. The first threshold can be pre-configured or pre-defined, and is not limited here.

[0298] In this embodiment, the terminal triggers an L3 measurement report when at least one of the above conditions is met, meaning that the terminal can initiate an L3 measurement report independently without the need for instructions from the network-side device.

[0299] As an optional embodiment, when the use of the SSB includes beam failure detection, the method further includes at least one of the following:

[0300] If the SSB stops transmitting when it is aperiodic, then the configuration information for beam failure detection corresponding to the SSB is determined to be invalid.

[0301] When the SSB is aperiodic transmission, beam failure detection is performed for the duration indicated by the beam failure detection configuration information.

[0302] In this embodiment, if the transmission time of the on-demand SSB is non-periodic, i.e., it only transmits for a period of time and then stops transmitting, then when the on-demand SSB transmission stops, the terminal considers the previously configured beam failure detection configuration of the on-demand SSB to be invalid; and / or, when the network-side device configures beam failure detection for the terminal, it adds a valid duration, which represents the valid detection duration for beam failure detection of the on-demand SSB. Once this time is exceeded, the terminal will no longer perform beam failure detection. In some embodiments, when the network-side device configures beam failure detection for the terminal, the configured valid duration can be a fixed value, or it can be the duration between the start time of SSB transmission and the stop time of SSB transmission.

[0303] As an optional embodiment, the method further includes:

[0304] If the second condition is met, it is determined that the measurement configuration information and / or beam failure detection configuration information corresponding to the SSB are not executed or are invalid, and the measurement configuration information includes L1 measurement configuration information and / or L3 measurement configuration information;

[0305] The second condition includes at least one of the following:

[0306] The secondary serving cell for transmitting SSBs has been released;

[0307] The secondary serving cell for transmitting SSB has been modified;

[0308] The secondary serving cell transmitting SSB is deactivated;

[0309] Received the status information (scg-State) of the secondary serving cell group transmitting the SSB;

[0310] The timer (sCellDeactivationTimer) of the secondary serving cell transmitting the SSB stops or expires.

[0311] In this embodiment, when one or more of the second conditions described above are met, it can be considered that the relevant measurements (L1 measurement and / or L3 measurement) and / or beam failure detection configuration of the on-demand SSB are also deactivated.

[0312] The implementation process of the SSB transmission method of this disclosure is illustrated below by way of example.

[0313] Example 1: The network-side device indicates the index of the SSB resource set and / or the index of the SSB.

[0314] Step 11: If on-demand SSB resource sets can be pre-configured, the network side pre-configures one or more on-demand SSB resource sets. Each on-demand SSB resource set includes different on-demand SSB configurations, such as at least one of the following: on-demand SSB resource set index, SSB index, ssb-PositionsInBurst, SSB transmission period, SSB transmission frequency, SSB transmission duration, etc. If the on-demand SSB resource set index is not configured in the on-demand SSB resource set, the index of the on-demand SSB resource set can be implicitly indicated.

[0315] Step 12: For scenario 1 shown in Figure 1, the network-side device can configure the on-demand SSB resource set index and / or SSB index and its transmission status in the RRC message. For example, if the transmission status of on-demand SSB resource set 1 is configured as transmission (or activation) in the RRC message, such as {activated}, it means that the SCell is sending with on-demand SSB resource set 1. If the RRC message does not carry the transmission status of on-demand SSB resource set 1 or the transmission status is configured as non-transmission (deactivated), such as {deactivated}, it means that on-demand SSB resource set 1 is not activated.

[0316] Step 13: For scenario 1, if there is a need for on-demand SSB transmission, the network-side device can indicate the transmission (or activation) of on-demand SSB through indication signaling. This indication signaling can be DCI or MAC CE, and the content of the signaling may include, but is not limited to, one or more of the following:

[0317] a) The signaling content is: the resource set index and / or SSB index of the transmitted on-demand SSB, indicating that the SSB corresponding to the on-demand resource set index and / or SSB index has been transmitted (or activated). For example, if the signaling content is on-demand SSB resource set 1, the terminal believes that on-demand SSB resource set 1 has been transmitted (or activated).

[0318] b) The signaling content consists of the transmitted on-demand SSB resource set index and SSB index, indicating that the SSB corresponding to the SSB index has been transmitted (or activated), and the configuration information of this SSB is the configuration information within the SSB resource set index. The network-side device can send the on-demand SSB resource set index and SSB index as two separate signaling messages or as a single signaling message.

[0319] c) The signaling content includes: the resource set index and / or SSB index of the transmitted on-demand SSB, and / or the transmission status of the transmitted (or activated) SSBs. This indicates that the transmitted (or activated) SSB resource set is configured to continue transmission (or not be deactivated), and SSB transmission is performed according to the original configuration information of the transmitted (or activated) SSB resource set and the new configuration information of the on-demand SSB resource set. For example, at time T1, the signaling content is on-demand SSB resource set 2 and indicates that the status of on-demand SSB resource set 1 is transmission (or activation), such as {activated}. In this case, the terminal believes that both on-demand SSB resource set 2 and on-demand SSB resource set 1 will be transmitted after time T2.

[0320] For example, if the signaling content at time T1 is on-demand SSB resource set 2 and indicates that the state of on-demand SSB resource set 1 is not transmitting (or deactivated), such as {deactivated}, or does not indicate the state of on-demand SSB resource set 1, then the terminal believes that only on-demand SSB resource set 2 will be transmitted after time T2. All {activated} and {deactivated} values ​​described in the embodiments of this disclosure can also be represented by 0 / 1 bits or other forms, as long as they can represent active and deactivated states; no specific limitations are made here.

[0321] d) The signaling content is: the resource set index and / or SSB index of the transmitted on-demand SSB. This indicates that SSB transmission is in progress, and the previously transmitted SSB continues to be transmitted. For example: at time T1, the signaling content is on-demand SSB resource set 1; at time T2, the signaling content is on-demand SSB resource set 2. In this case, the terminal assumes that both on-demand SSB resource set 1 and on-demand SSB resource set 2 will be transmitted after time T2.

[0322] e) The signaling content includes: the transmitted (or activated) on-demand SSB resource set index and / or on-demand SSB index, and / or the non-transmitted (or deactivated) on-demand SSB resource set index and / or on-demand SSB index, indicating the transmission status of the on-demand SSB resource set index and / or on-demand SSB index. That is, it configures a list of on-demand SSB transmission (or activation) and / or non-transmission (or deactivation) lists, which contain the on-demand SSB index and / or on-demand SSB resource set index. For example, if the transmission (or activation) list contains on-demand SSB resource set index1 at time T1, and the transmission (or activation) list contains on-demand SSB resource set 2 at time T2, then the terminal considers there to be two transmission (or activation) SSB resource sets at time T2. If the transmission (or activation) list contains on-demand SSB resource set 3, and the non-transmission (or deactivation) list contains on-demand SSB resource set 1, then the terminal considers there to be two transmission (or activation) SSB resource sets, SSB resource set 2 and SSB resource set 3, at time T3.

[0323] f) The network-side device indicates the transmission status of the on-demand SSB resource set index and / or the on-demand SSB index in the form of a bitmap. For example, if the transmission status of the on-demand SSB resource set is 00000001 at time T1, it means that on-demand SSB resource sets 0-6 are not transmitted (or deactivated), and on-demand resource set 7 is transmitted (or activated).

[0324] Step 14: For scenario 2 or scenario 3 shown in Figure 1, if there is a need for on-demand SSB transmission, the network-side device indicates the on-demand SSB transmission (or activation). The indication signaling can be given through enhanced traditional SCell Activation / Deactivation MAC CE or Enhanced SCell Activation / Deactivation MAC CE signaling, or through the new DCI / MAC CE signaling. If there is no need for on-demand SSB transmission, the network-side device does not need to send any signaling regarding on-demand SSB transmission (or activation). The content of the indication signaling is similar to that in step 13 and will not be repeated here.

[0325] Step 15: For scenario 4 in Figure 1, after the SCell is fully activated, if there is a need for on-demand SSB transmission, the network-side device indicates the transmission (or activation) of on-demand SSB; if there is no need for on-demand SSB transmission, the network-side device does not need to send any signaling regarding on-demand SSB transmission (or activation). The content of the indication signaling is similar to that in step 13, and will not be repeated here.

[0326] It should be noted that the execution order of steps 11 to 15 is not limited here, and all of the above steps are optional. Steps 11 to 15 can be executed independently or multiple steps can be executed.

[0327] Example 2: Network-side device indicates BWP handover.

[0328] Step 21: Refer to step 11 of Example 1 above, which will not be repeated here.

[0329] Step 22: Refer to steps 12 to 15 of Example 1 above, which will not be repeated here.

[0330] Step 23: For scenario 4, if there is a need for on-demand SSB transmission, the network-side device indicates on-demand SSB transmission (or activation). Additionally, if there is a BWP handover, the network-side device indicates on-demand SSB transmission (or activation) and BWP handover, with the indication method being at least one of the following:

[0331] a) If there is a BWP handover requirement, the network-side device indicates the BWP ID to be switched when indicating the transmission (or activation) of on-demand SSB. This indication information can be indicated by DCI or MAC CE signaling. The indication content of on-demand SSB transmission (or activation) refers to step 13 in Example 1 above.

[0332] b) If there is a BWP handover requirement, the network-side device indicates the transmission (or activation) of the on-demand SSB when indicating the BWP handover. This indication information can be indicated by enhancing the original DCI BWP handover signaling. The indication content of the transmission (or activation) of the on-demand SSB is the same as step 13 in Example 1 above; or, this indication information is indicated by the new DCI / MAC CE signaling, which is similar to the indication method in a), and will not be described in detail here.

[0333] c) If a BWP handover is required, the network-side device can instruct the BWP handover and on-demand SSB transmission (or activation) respectively. In some embodiments, the network-side device can instruct the BWP handover using the original BWP handover signaling or the new DCI or MAC CE signaling, and the network-side device can instruct the SSB transmission using DCI or MAC CE.

[0334] Step 24: If the target BWP for the terminal's BWP switching is the default BWP or the dormitory BWP, the possible configuration and activation instructions for the default BWP or the dormitory BWP include, but are not limited to, the following:

[0335] 1) For default BWP / dormant BWP, on-demand SSB can be pre-configured during BWP configuration. This on-demand SSB may include the SSB's transmission cycle, frequency, and some configurations such as ssb-PositionsInBurst.

[0336] If the network-side device does not have certain pre-configured parameters, the on-demand SSB configuration before switching to the default BWP / dormant BWP will be reused. That is, when the terminal's BWP switches to the default BWP / dormant BWP, its on-demand SSB configuration can default to the on-demand SSB configuration during BWP pre-configuration (if it exists). For example, during pre-configuration, the on-demand SSB periodic configuration is set in the default BWP / dormant BWP configuration, while other configurations are missing. When the terminal switches to the default BWP / dormant BWP, the periodic configuration will be applied and changed, while other configurations remain unchanged. This BWP switching includes the terminal automatically switching to the default BWP / dormant BWP after the timer expires.

[0337] 2) For dormant BWP, when the network-side device instructs the terminal to switch to dormant BWP, it can indicate the on-demand SSB index and / or SSB resource set index after the switch. The on-demand SSB resource set may contain the SSB resource set index and / or SSB index and / or ssb-PositionsInBurst and / or transmission period and / or transmission frequency, etc.

[0338] 3) In the event of a BWP handover, the on-demand SSB period after the handover can be indicated, meaning that other configurations remain unchanged, only the on-demand SSB transmission period is changed.

[0339] It should be noted that the execution order of steps 21 to 24 is not limited here, and all of the above steps are optional. Steps 21 to 24 can be executed independently or multiple steps can be executed.

[0340] Example 3: Network-side devices indicate the purpose of the SSB.

[0341] Step 31: The network-side device pre-configures one or more on-demand SSB resource sets, which is similar to step 11 in Example 1, and will not be repeated here.

[0342] Step 32: The network-side device sends the index of the on-demand SSB resource set and / or the on-demand SSB index, and / or the scope of application (i.e., purpose) of the activated on-demand SSB. The signaling content of the scope of application of the activated on-demand SSB sent by the network-side device includes, but is not limited to, one of the following:

[0343] i) The scope of application of bitmap format, such as on-demand SSB 1, may include: 001 represents BFD being effective and L1 / L3 measurement being invalid; 100 represents L3 measurement being effective and L1 measurement and BFD being invalid.

[0344] ii) Index of the scope of application of on-demand SSB, such as on-demand SSB1, whose scope may include: 00 represents (Beam Failure Detection, BFD), 01 represents L1 measurement, 10 represents L3 measurement, etc.; it may also include measurement reporting, such as 000 representing beam failure detection, 100 representing L3 measurement, 010 representing L3 measurement reporting, or 001 representing L3 measurement and reporting, etc.

[0345] The network-side device can send signaling indicating the scope of the active on-demand SSB together with the index of the SSB resource set or the index of the SSB in Example 1, or send it separately.

[0346] The signaling sent by the network-side device to activate the scope of the on-demand SSB can be one or more of the following:

[0347] RRC message;

[0348] DCI;

[0349] MAC CE;

[0350] This is used after enhancing the traditional SCell activation signaling SCell Activation / Deactivation MAC CE or Enhanced SCell Activation / Deactivation MAC CE.

[0351] Step 33: After receiving the signaling content from step 32, the terminal may perform at least one of the following actions:

[0352] a) Perform L3 and / or L1 measurements. After receiving the signaling content in step 32, the terminal begins to perform the measurements.

[0353] b) The terminal performs L3 and / or L1 measurements according to the SSB transmission instruction. For example: if the SSB was not transmitting before time T2, and the SSB is transmitting at time T2, indicating that the purpose of the SSB is L3 and / or L1 measurement, then the terminal performs SSB measurement according to the measurement configuration indicated by the base station side. Before time T2, although the measurement configuration was configured, the terminal did not use it to perform the measurement.

[0354] c) L3 and / or L1 measurement reports: If the purpose of the SSB is to indicate L3 and / or L1 measurement reports, the terminal will report the measurement results after the measurement.

[0355] d) Perform beam failure detection. The terminal performs beam failure detection for the SSB resource based on the beam failure detection.

[0356] Among them, a), b), and c) above may be executed individually or in combination, such as measuring first and then reporting.

[0357] Step 34: If the on-demand SSB transmission time is aperiodic, i.e., it only transmits for a period of time and then stops transmitting, the terminal's measurement and beam failure detection behaviors include, but are not limited to:

[0358] When the transmission of on-demand SSB stops, the terminal considers the previously configured beam failure detection configuration of on-demand SSB to be invalid, that is, the terminal no longer performs L1 / L3 measurements and beam failure detection for the on-demand SSB.

[0359] When configuring beam failure detection for the terminal, an effective duration is added. This effective duration represents the effective detection time for beam failure detection of the on-demand SSB. Once this time is exceeded, the terminal will no longer perform L1 / L3 measurements and beam failure detection for the on-demand SSB.

[0360] Step 35: When the SCell is deactivated, the terminal can assume that the associated L1 / L3 measurements and beam failure detection configurations of the on-demand SSB are also deactivated. SCell deactivation includes, but is not limited to:

[0361] When the SCell is released or modified;

[0362] When SCell is deactivated;

[0363] When the terminal receives scg-State;

[0364] When the SCell's sCellDeactivationTimer expires, the SCell is considered deactivated.

[0365] It should be noted that the execution order of steps 31 to 35 is not limited here, and all of the above steps are optional. Steps 31 to 35 can be executed independently or multiple steps can be executed.

[0366] Example 4: Terminal reports L3 measurement report.

[0367] Step 41 is similar to step 11 in Example 1 above, and will not be repeated here.

[0368] Step 42 is similar to steps 12 to 15 in Example 1 above, and will not be repeated here.

[0369] Step 43: The terminal triggers an L3 measurement report when at least one of the following conditions is met:

[0370] a) The secondary serving cell is an unknown cell; that is, when the cell is an unknown cell, the terminal triggers an L3 measurement report in order to turn the cell into a known cell and reduce the cell activation latency.

[0371] b) After receiving the SSB transmission instruction, the terminal triggers an L3 measurement report and reports the measurement results based on the latest serving cell measurement results obtained from the SSB transmission instruction.

[0372] c) The time interval between the current time and the last reported measurement result of the secondary cell is greater than a first threshold. The threshold can be indicated by the base station or be a default value. For example, if the terminal reports an L3 measurement result at time T1, and the time interval between time T2 and time T1 is greater than the threshold, the terminal can trigger an L3 measurement report and report an L3 measurement result.

[0373] Based on Example 4 above, the terminal can promptly report the required L3 measurement results to the network-side device.

[0374] It should be noted that the execution order of steps 41 to 43 is not limited here, and all of the above steps are optional. The above steps can be executed independently or multiple steps can be executed.

[0375] In this embodiment, the signaling content and terminal behavior related to the on-demand SSB activation process are designed. Through this embodiment, the network-side device can change the index, configuration, and purpose of the on-demand SSB through the transmission (or activation) signaling of the on-demand SSB, and combine the transmission (or activation) of the on-demand SSB with BWP to reduce the related signaling process and avoid unnecessary terminal behavior.

[0376] In embodiments of this disclosure, the network-side device sends first information to the terminal to indicate SSB transmission, such as the identifier of the target BWP corresponding to the BWP switching, the purpose of the SSB, the index of the SSB resource set, and one or more of the SSB indexes. Based on this first information, the terminal can accurately determine the SSB transmitted by the network-side device, avoiding unnecessary signaling processes and terminal actions, effectively reducing transmission power consumption and improving transmission efficiency.

[0377] As shown in Figure 3, this disclosure also provides an SSB transmission method applied to a network-side device, including:

[0378] Step 301: The network-side device sends first information to the terminal, the first information being used to indicate the transmission of SSB;

[0379] The first information includes at least one of the following:

[0380] BWP switches to the identifier of the corresponding target BWP;

[0381] The uses of SSB;

[0382] Index of the SSB resource collection;

[0383] Index of SSB.

[0384] In this embodiment, the network-side device sends first information to the terminal to indicate SSB transmission. This allows the terminal to determine the transmitted SSB based on the first information, and / or to determine how to use the SSB in subsequent measurements or beam failure detection, and / or to determine the activated SSB, and / or the deactivated SSB, thereby avoiding unnecessary signaling processes and terminal behavior. The SSB can be an on-demand SSB. In some embodiments, the first information is used to indicate SSB transmission, but it can also be understood as indicating SSB activation and / or deactivation.

[0385] In embodiments of this disclosure, the network-side device sends first information to the terminal to indicate SSB transmission, such as the identifier of the target BWP corresponding to the BWP switching, the purpose of the SSB, the index of the SSB resource set, and one or more of the SSB indexes. Based on this first information, the terminal can accurately determine the SSB transmitted by the network-side device, avoiding unnecessary signaling processes and terminal actions, effectively reducing transmission power consumption and improving transmission efficiency.

[0386] In some embodiments, sending the first information to the terminal includes: sending multiple pieces of information in the first information through one signaling or through multiple signaling.

[0387] In this embodiment, for one or more of the above-mentioned first information, the network-side device can send multiple first information simultaneously through one signaling, or it can send each first information separately through multiple signaling.

[0388] As an optional embodiment, the method further includes:

[0389] The configuration information of the SSB resource set is sent to the terminal, and the configuration information of the SSB resource set includes at least one of the following:

[0390] 1) Index of SSB resource set; The network-side device can pre-configure one or more indexes of SSB resource sets, and can subsequently send the index of a certain SSB resource set to the terminal to indicate whether to activate or deactivate the SSB resource set corresponding to that index.

[0391] 2) SSB Index; The network-side device can configure one or more SSB indexes in the SSB resource set. Subsequently, it can send the index of a certain SSB resource set to the terminal, and then the SSB index will be transmitted.

[0392] 3) Duration of SSB transmission; the duration for which the index of the SSB resource set and / or the index of the SSB configured by the network-side device will no longer be transmitted after the specified duration.

[0393] 4) SSB transmission period; By pre-configuring the SSB transmission period, the terminal can receive SSBs transmitted by the network-side device based on the pre-configured period.

[0394] 5) SSB PositionsInBurst: By configuring the transmission position of the SSB, the transmission of the SSB is indicated.

[0395] 6) SSB transmission frequency; By pre-configuring the SSB transmission frequency, the terminal can receive SSBs transmitted by the network-side device based on the pre-configured frequency.

[0396] In this embodiment, the network-side device can pre-configure SSB resource sets and their configuration information for the terminal. For example, it can pre-configure one or more SSB resource set indexes, one or more SSB indexes, and one or more information such as SSB transmission duration, transmission period, transmission frequency, and transmission bitmap. By pre-configuring the SSB resource set configuration information, the terminal can subsequently be shown the indexes of active or deactivated SSB resource sets and / or SSB indexes, and the terminal can learn about the SSBs transmitted by the network-side device based on the pre-configured information.

[0397] As an optional embodiment, the first information is also used to indicate BWP switching;

[0398] The method further includes sending configuration information to the terminal, the configuration information including BWP configuration information and / or SSB pre-configuration information.

[0399] In this embodiment, the first information can also indicate BWP switching. For example, when the network-side device indicates the transmission (or activation) of a certain on-demand SSB, if there is a simultaneous BWP switching, it can send SSB transmission (or activation) signaling to the terminal. This signaling includes the transmitted (or activated) SSB index and / or SSB resource set (SSB), as well as the identifier of the target BWP corresponding to the BWP switching. That is, the network-side device indicates the switching BWP ID simultaneously when indicating the transmission (or activation) of the on-demand SSB. Alternatively, the network-side device indicates the transmission (or activation) of the on-demand SSB simultaneously when indicating BWP switching. It should be noted that the network-side device can indicate the SSB index and / or SSB resource set index and / or BWP ID through one or more signaling messages.

[0400] Network-side devices can pre-configure SSB-related information when configuring a BWP for a terminal, such as SSB transmission period, frequency, and SSB-PositionsInBurst. When a terminal performs a BWP handover to a default BWP (and / or dormant BWP), if some SSB information was configured during BWP pre-configuration, the corresponding on-demand SSB configuration can be changed to the configuration used during BWP pre-configuration. That is, the terminal can determine the relevant SSB parameters after the BWP handover based on the pre-configured SSB parameters, such as transmission period, frequency, and location, and can then use these pre-configured parameters to receive the SSB. If the network-side device has not pre-configured some SSB information, the terminal can determine the relevant SSB parameters after the BWP handover based on the SSB configuration before the handover, such as transmission period, frequency, and location, and can then reuse the on-demand SSB configuration from before the handover to receive the SSB.

[0401] In some embodiments, in the event of a BWP handover, the first information further includes: the transmission cycle of the SSB after the BWP handover.

[0402] In this embodiment, when a BWP handover occurs, the network-side device can indicate the on-demand SSB period after the handover at the same time as indicating the BWP handover.

[0403] As an optional embodiment, the SSB may be used for at least one of the following purposes:

[0404] 1) L1 measurement; that is, the network-side device indicates to the terminal that the purpose of the SSB is L1 measurement. For example, if the network-side device sends the SSB index to the terminal and the purpose of the SSB is L1 measurement, it means that the SSB corresponding to the indicated SSB index is used for L1 measurement and / or L1 measurement reporting.

[0405] 2) L3 measurement; that is, the network-side device indicates to the terminal that the purpose of the SSB is L3 measurement. For example, if the network-side device sends the SSB index to the terminal and states that the purpose of the SSB is L3 measurement, it means that the SSB corresponding to the indicated SSB index is used for L3 measurement and / or L3 measurement reporting. In some embodiments, the L3 measurement is a measurement obtained from the RRC layer.

[0406] 3) Beam failure detection, whereby the network-side device indicates to the terminal that the purpose of the SSB is beam failure detection. For example, the network-side device sends the SSB index to the terminal and states that the purpose of the SSB is beam failure detection, indicating that the SSB corresponding to the indicated SSB index is used for beam failure detection.

[0407] In some embodiments, where the purpose of the SSB is L1 measurement, the SSB is used to trigger at least one of the following operations in the L1 measurement:

[0408] Perform L1 measurements; for example, the SSB indicated by the network-side device is used to perform L1 measurements.

[0409] L1 measurement configuration update; for example, the SSB indicated by the network-side device is used to perform L1 measurement configuration update; for example, before the terminal receives the SSB or receives the purpose of the SSB sent by the network-side device, L1 measurement is not performed. After receiving the purpose of the SSB indicated by the network side, the terminal updates the L1 measurement configuration according to the L1 measurement configuration information pre-configured by the network side and performs L1 measurement.

[0410] L1 measurement report; in this case, it is assumed that the network-side device triggers the terminal's L1 measurement report by indicating the first information.

[0411] And / or, if the purpose of the SSB is L3 measurement, the SSB is used to trigger at least one of the following operations in the L3 measurement:

[0412] Perform L3 measurements; for example, the SSB indicated by the network-side device is used to perform L3 measurements.

[0413] L3 measurement configuration update; for example, the SSB indicated by the network-side device is used to perform L3 measurement configuration update; for example, before the terminal receives the SSB or receives the purpose of the SSB sent by the network-side device, L3 measurement is not performed. After receiving the purpose of the SSB indicated by the network side, the terminal updates the L3 measurement configuration according to the L3 measurement configuration information pre-configured by the network side and performs L3 measurement.

[0414] In the case of an L3 measurement report, it is assumed that the network-side device triggers the terminal's L3 measurement report by indicating the first information.

[0415] In some embodiments, the network-side device may indicate the purpose of the SSB in the form of a bitmap, for example, 001 represents BFD enabled and L1 / L3 measurement invalid. Alternatively, it may indicate the index corresponding to the purpose of the SSB, for example, 00 represents BFD, 01 represents L1 measurement, 10 represents L3 measurement, etc. The method by which the network-side device indicates the purpose of the SSB is not limited here.

[0416] It should be noted that the network-side device in this embodiment can implement all the steps implemented by the network-side device in the above-described embodiment applied to the terminal, and can achieve the same technical effect. Therefore, the parts and beneficial effects that are the same as those in the above-described embodiment applied to the terminal will not be described in detail here.
