Description

An information transmission method, apparatus and equipment

[0001] This disclosure claims priority to Chinese Patent Application No. 202410184894.8, filed on February 19, 2024, entitled "An Information Transmission Method, Apparatus and Device", 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 an information transmission method, apparatus and device. Background Technology

[0003] The Synchronization Signal / PBCH Block (SSB) in the current system is a periodic signal. Each SSB's number and location are indicated by its SSB PositionsInBurst. In Carrier Aggregation (CA) scenarios, the SSB configuration of the Primary Cell (PCell) is transmitted via System Information Block (SIB) 1, while the SSB configuration of the Secondary Cell (SCell) is transmitted separately for each SCell via Radio Resource Control (RRC). The base station then continuously transmits SSBs according to the configuration; simultaneously, to ensure coverage within the cell, beam scanning transmission of SSBs from multiple directions may be used. This leads to scenarios where unnecessary SSB transmissions may occur, resulting in higher network and terminal power consumption.

[0209] Figure 1 shows a block diagram of a wireless communication system applicable to embodiments of the present disclosure. The wireless communication system includes a terminal device (also referred to simply as a terminal) and a network device.

[0210] The terminal devices involved in the embodiments of this disclosure can be devices that provide voice and / or data connectivity to users, handheld devices with wireless connectivity, or other processing devices connected to a wireless modem. The names of the terminal devices may differ in different systems; for example, in a 5G system, a terminal device can be called User Equipment (UE). Wireless terminal devices can communicate with one or more core networks (CNs) via a Radio Access Network (RAN). Wireless terminal devices can be mobile terminal devices, such as mobile phones (or "cellular" phones) and computers with mobile terminal devices, for example, portable, pocket-sized, handheld, computer-embedded, or vehicle-mounted mobile devices that exchange voice and / or data with the RAN. Examples include Personal Communication Service (PCS) phones, cordless phones, Session Initiated Protocol (SIP) phones, Wireless Local Loop (WLL) stations, and Personal Digital Assistants (PDAs). Wireless terminal equipment can also be referred to as a system, subscriber unit, subscriber station, mobile station, mobile station, remote station, access point, remote terminal, access terminal, user terminal, user agent, or user device, but this application does not limit the terminology.

[0211] The network device involved in this disclosure can be a base station, which may include multiple cells providing services to terminals. Depending on the specific application, the base station may also be called an access point, or a device in the access network that communicates with the wireless terminal device through one or more sectors on the air interface, or other names.

[0213] The following is a description of the solutions provided in the embodiments of this disclosure.

[0214] Currently, SSB transmission is periodic, and base stations cannot shut it down according to service requirements. Furthermore, user distribution is not considered; even if there are no users in a certain direction, SSBs may still be transmitted in that direction. Therefore, base stations cannot dynamically adjust SSB transmission and shutdown according to actual scenario needs, and can only update SSB parameters through static signaling SIB1 or RRC; this results in high network and terminal power consumption.

[0215] Based on the above, this disclosure provides an information transmission method, apparatus, and device to solve the problem of high energy consumption in SSB transmission in related technologies. The method, apparatus, and device are based on the same concept, and since the principles by which they solve the problem are similar, their implementations can be referred to interchangeably, and repeated details will not be repeated.

[0216] The information transmission method provided in this disclosure is applied to a network device, as shown in FIG2. The method includes:

[0217] Step 21: Send a Synchronization Signal Block (SSB) transmission signaling to the terminal. The SSB transmission signaling includes a first signaling, which is used to trigger the transmission of the SSB, or the first signaling is used to trigger the transmission of the SSB and to stop the transmission of the SSB; or the SSB transmission signaling includes a second signaling and a third signaling, whereby the second signaling is used to trigger the transmission of the SSB and the third signaling is used to stop the transmission of the SSB; wherein the SSB transmission signaling carries SSB transmission parameter information.

[0218] In the case where "the first signaling is used to trigger the transmission of an SSB", the stop of the SSB transmission can be triggered by the occurrence of a predefined event; and / or, the SSB transmission signaling can be an indication to activate or deactivate a certain SSB transmission, but is not limited thereto.

[0219] In some embodiments, after step 21, the method may further include: sending an SSB according to the SSB transmission signaling, but this is not limited to this. For specific details, please refer to the terminal side (e.g., sending an SSB according to the SSB transmission signaling and the first identifier below), which will not be repeated here.

This method supports dynamically activating or deactivating SSB transmission, thereby avoiding energy waste caused by continuous SSB transmission, reducing SSB transmission energy consumption, achieving energy saving for network devices and terminals, and solving the problem of high SSB transmission energy consumption in related technologies.

[0221] The transmission parameter information includes at least one of the following: SSB time index information; SSB location information within the burst set; an index of a pattern in a predefined or network device-configured SSB pattern; SSB start time information; SSB duration information; and SSB function indication parameters.

This also supports measurement reporting when SSB transmission is triggered, further reducing the power consumption of network devices and terminals. "Used to trigger the terminal to report measurement results" can include: explicit or implicit triggering of the terminal to report measurement results, which is not limited here.

[0225] In some embodiments, at least one of the first, second, and third signaling signals carries a reporting configuration identifier, which is used to trigger the reporting corresponding to the corresponding reporting configuration (i.e., the reporting configuration corresponding to the reporting configuration identifier). This supports accurate triggering of the corresponding measurement reporting.

[0226] In some embodiments, the information transmission method further includes: stopping the transmission of the SSB upon the occurrence of a first event; wherein the first event includes at least one of the following: cell addition; cell deletion; cell modification; and terminal channel state information (CSI) reporting.

[0239] The SSB function indication parameter indicates at least one of the following: SSB measurement; secondary cell SCell activation; downlink synchronization. This ensures accurate indication of the SSB function.

[0240] In some embodiments, the SSB transmission signaling is Downlink Control Information (DCI) signaling or Media Access Control (MAC-CE) signaling. This allows for multiple implementation methods of this scheme.

[0241] It should be noted that the relevant content on the network device side and the terminal side can be referred to each other, and the repeated parts will not be repeated.

[0242] The information transmission method provided in the embodiments of this disclosure will be illustrated below with examples, using a base station as an example of a network device.

[0243] To address the aforementioned technical problems, this disclosure provides an information transmission method, specifically an on-demand SSB transmission method, which can be understood as an on-demand SSB transmission mechanism.

Simultaneously, the signaling can also trigger SSB transmission in a specific direction and / or trigger corresponding Channel State Information (CSI) measurement reporting (this reporting can include SSB and / or CSI-RS reporting); thereby supporting energy-saving functions in various scenarios such as measurement, cell activation, and downlink synchronization. This solution mainly involves the base station side and the terminal side, which will be described separately below.

[0273] 9) The activation signaling and / or deactivation signaling mentioned in 1) can be either DCI or MAC-CE.

[0274] It should be noted that the relevant content on the base station side and the terminal side can be referred to each other, and the repeated parts will not be repeated.

[0275] The following provides specific examples illustrating the solutions provided in the embodiments of this disclosure.

[0276] Example 1:

[0277] Suppose that the base station needs to activate SCells for the terminal based on the current downlink service transmission requirements. In one implementation, the base station will activate all inactive SCells for the terminal. In the New Radio (NR) protocol, the terminal's SCells and PCells are numbered using the ServingCellIndex and configured for the UE. In this embodiment, it is assumed that two SCells are activated for the terminal, numbered ServingCell_index1 and ServingCell_index2. It is also assumed that there are no SSB transmissions before these two SCells are activated, meaning the base station cannot obtain the channel quality of the SCells. In one implementation, the base station can configure energy-saving cell identifiers for ServingCell_index1 and ServingCell_index2 respectively, indicating that there are no SSB transmissions before their activation. In this way, ServingCell_index1 and ServingCell_index2 are both unknown cells (e.g., cells that the UE has not measured for a period of time, but this is not a limitation).

[0278] To reduce SCell activation latency, the base station can send on-demand SSB activation signaling to the terminal, instructing ServingCell_index1 and ServingCell_index2 to transmit on-demand SSB. In one embodiment, the activation signaling may include a status value indication field for the corresponding serving cell index, as shown in the table below. When the status value is 1, it indicates that on-demand SSB is activated for transmission; otherwise, a value of 0 indicates that on-demand SSB is not activated for transmission.

[0279] In addition, in one implementation, the base station configures one or more on-demand SSB parameter sets (corresponding to the parameter information mentioned above) for the serving cell via RRC signaling or through a system-predefined method. Each parameter set may include one or more of the following parameters:

[0280] The number and location of SSBs in an SSB burst (which can be indicated using a bitmap);

[0281] SSB cycle;

[0282] SSB subcarrier spacing;

[0283] SSB power;

[0284] SSB duration;

[0285] SSB start time.

[0286] The SSB duration represents the length of time after SSB activation, after which transmission ceases; it can be expressed as the number of transmission cycles or the duration (e.g., milliseconds or seconds). The SSB start time can be based on the time of receiving the activation signaling, indicating the offset time relative to this reference point, such as the offset sign, subframe, or milliseconds; or it can be determined by a reserved position for SSB transmission, for example, defined as starting from a certain reserved position after receiving the activation signaling. The SSB duration and SSB start time can be configured independently for each SCell, or shared by multiple or all cells.

[0287] For the above parameter set, for example, RRC signaling is configured with 4 types, as shown in the table below:

[0288] The SSB duration 3 can represent a duration of 3 cycles; the SSB start time 1 can represent the SSB time domain position reserved according to the cycle, and the transmission starts when the first reserved time domain position is received after the activation signaling.

[0289] The on-demand SSB activation signaling sent by the base station to the terminal may include an indication of the on-demand SSB parameter set corresponding to the SCell. One method is shown in the table below, which indicates the parameter index corresponding to each SCell; that is, ServingCell_index1 uses the parameter set with index 2, and ServingCell_index2 uses the parameter set with index 3.

[0290] In some embodiments, the values ​​of on-demand SSB parameters can also be directly indicated in the on-demand SSB activation signaling. For example, the SSB period of ServingCell_index1 can be indicated as 5ms, the number and position of SSBs in the SSB burst set can be 1001, and the SSB duration can be 3, etc. Unindicated SSB parameters can be configured independently by RRC for each SCell, but are not limited to this.

[0291] In another implementation, multiple or all SCells can be instructed to share a single parameter index. For example, the on-demand SSB parameter set index 4 can be used for both ServingCell_index1 and ServingCell_index2. For scenarios where multiple SCells share a single parameter index, the specific SCells sharing the same index can be determined by the protocol. For instance, the protocol can specify that SCells configured in the same simultaneous update list (such as the simultaneousU-TCI-UpdateList1-r17 list) share a single parameter.

[0292] Based on the above, after receiving the on-demand SSB activation signaling, the terminal can measure the SSBs on ServingCell_index1 and ServingCell_index2 to determine the channel quality of the corresponding cell; thus supporting the determination of whether to activate the SSB based on the channel quality.

[0293] Subsequently, the base station sends an SCell activation signaling message, which may include an activation indication field for the corresponding SCell (which may carry an activation status indication). In one embodiment, the SCell activation signaling message may also include an SSB activation indication for the corresponding SCell's SSB burst set (this indication can notify the UE of the SSB to be transmitted, truly activating the SSB transmission). This indication can be used to indicate that one or more SSBs in the SSB burst set are activated for transmission. Specifically, determining which SSB is activated for transmission can be determined by the base station based on the obtained terminal location information, or by the terminal reporting the results of on-demand SSB measurements; for example, the base station obtains the SSB activation indication and sends it to the terminal; specifically, the base station may obtain some prior information and then coordinate it with new information such as the SSB activation signaling to indicate. The SSB activation indication can use a bitmap indication (such as using the number and position of SSBs in the aforementioned SSB burst set) or an SSB index (corresponding to the aforementioned SSB time index information); for example, using a bitmap indication, as shown in the table below:

[0294] In this context, 0001 indicates that for ServingCell_index1, its SSB burst contains 4 possible SSBs, with only the fourth SSB being activated and transmitted. 0100 indicates that for ServingCell_index2, its SSB burst contains 4 possible SSBs, with only the second SSB being activated and transmitted. The SCell activation signaling may also include an SSB start time. Starting from this start time, the base station will send the fourth SSB on ServingCell_index1 according to the SSB cycle configured by RRC; and on ServingCell_index2, it will send the second SSB according to the SSB cycle configured by RRC; the base station will stop sending SSBs only after the terminal receives the SCell deactivation signaling (specifically, the base station could send a deactivation command and then stop sending SSBs, but this is not a limitation). The RRC configuration here can adopt the configuration method currently used in the protocol, with parameters such as the SSB cycle configured independently for each ServingCell. In one embodiment, the SCell deactivation signaling may also include an SSB deactivation indication in the SSB burst set corresponding to the SCell (this indication can notify the UE to stop the transmission of the SSB and actually deactivate the SSB transmission), which is used to indicate that one or more SSBs in the SSB burst set are deactivated for transmission.

[0295] The working process of this embodiment can be shown in Figure 4 (where on-demand SSB-1 can represent the SSB activated by on-demand SSB activation signaling for measurement, on-demand SSB-2 can represent the SSB activated by SCell activation signaling, and the dashed box can represent an SSB that is not sent); since on-demand SSB activation has been performed once, the terminal performs measurement (L1 / L3 (layer 1 or layer 3) measurement), which can convert the unknown SCell into a known SCell. In subsequent SCell activation, faster activation is achieved, shortening the SCell activation time.

[0296] In another implementation, the SCell activation signaling may not include the SSB activation indication in the corresponding SCell's SSB burst set, but is only used to indicate to the terminal that the SCell has been activated. In this case, no SSB corresponding to this SCell activation signaling begins transmission, meaning it does not change existing SSB transmission; and / or the SCell deactivation signaling also does not include the SSB deactivation indication in the corresponding SCell's SSB burst set, meaning it does not change or stop SSB transmission. As shown in Figure 5, the on-demand SSB activation signaling activates SSB transmission 8 times, while the SCell activation and SCell deactivation signaling do not change the transmission of this SSB, but are only used to notify the terminal to activate or deactivate this SCell.

[0297] Example 2:

[0298] Suppose a base station needs to add or delete a SCell. Since there is no SSB transmission on the SCell to be added or deleted, the base station needs to trigger on-demand SSB to perform measurements. Based on the measurement results, the base station determines whether to add or delete the SCell. Building upon the on-demand SSB activation signaling described in Example 1, the on-demand SSB activation signaling can also indicate measurement reporting configuration information (such as the aforementioned reporting configuration ID), or the activation signaling can implicitly associate reporting configuration information. For example, for ServingCell_index1, the base station configures multiple reporting configurations for the terminal. In this example, it is assumed that there are two reporting configurations, represented as ReportConfig-1 and ReportConfig-2 (or Measurement Identifier (MeasID)-1 and MeasID-2); then, the on-demand SSB activation signaling can explicitly indicate whether the corresponding reporting configuration is ReportConfig-1 or ReportConfig-2. Afterwards, the terminal performs on-demand SSB measurements according to the reporting configuration and reports the measurement results according to the format in ReportConfig-1 or ReportConfig-2.

[0299] Another implementation is that in the on-demand SSB activation signaling, for the corresponding SCell, only it indicates whether to report the measurement results. As shown in the table below, it instructs ServingCell_index1 to report the measurement results, while ServingCell_index2 does not report the measurement results.

[0300] In another implementation, reporting can be performed through implicit association. For example, for measurement reporting configured in the mobility management process for a specific cell, when the on-demand SSB activation signaling indicates that on-demand SSB activation transmission is enabled for this cell, the measurement reporting configured in Radio Resource Management (RRM) automatically takes effect. Subsequently, the terminal will report the measurement reporting results corresponding to this cell as configured through the MeasObject (which can be understood as reporting according to the cell's corresponding parameter configuration (e.g., instructions on how to measure, how to report, etc.)). For example, in the RRM configuration, the base station configures the measurement reporting method for cell 0 (i.e., physical cell identifier PCID = 0) through the MeasObject. When on-demand SSB activation of on-demand SSB transmission in cell 0, the terminal will report the measurements configured according to the MeasObject.

[0301] The workflow in this embodiment is shown in Figure 6. Since measurement reporting is only performed when on-demand SSB transmission is triggered, the power consumption of the base station and the terminal is reduced.

[0302] Furthermore, the solution in Example 2 can be used in combination with that in Example 1, and this is not a limitation.

[0303] Example 3:

[0304] In Example 1, on-demand SSB activation and SCell activation were indicated using different signaling. In this example, the same signaling can be used. For example, both can use on-demand SSB activation signaling. For instance, for on-demand SSB used for measurement (corresponding to on-demand SSB-1 in Figure 7), the activation signaling (e.g., On-demand SSB activation-1) indicates an SSB duration of 3. For on-demand SSB activated by SCell (corresponding to on-demand SSB-2 in Figure 7), the activation signaling (e.g., On-demand SSB activation-2) indicates an SSB duration of 6. Thus, no additional deactivation signaling is needed to indicate deactivation after SCell activation.

[0305] In another implementation, the SSB duration parameter may not be indicated in the on-demand SSB activation signaling. Specifically, as shown in Figure 8, one approach is to use on-demand SSB deactivation signaling (e.g., On-demand SSB deactivation-1) to indicate that the SSB stops transmitting. The on-demand SSB deactivation signaling can be the same as the SCell deactivation signaling described in Embodiment 1 (e.g., On-demand SSB deactivation-2), or it can be the same as the on-demand SSB activation signaling, for example, simply changing the activation status indicator from 1 to 0.

[0306] Alternatively, another implementation method is to stop SSB transmission based on changes in events. For example, the event could be the addition, deletion, or modification of an SCell, or a CSI report from the terminal.

[0307] In some embodiments, the on-demand SSB activation signaling may further include an SSB function indication field (corresponding to the on-demand SSB function indication parameter described above). For example, this SSB function indication field indicates that this SSB is used for one of the following functions:

[0308] Measurement reporting (corresponding to the SSB measurement mentioned above);

[0309] SCell activation;

[0310] Downlink synchronization.

[0311] For example, each ServingCell may use 2 bits to indicate one of the functions, or multiple ServingCells or all ServingCells may use 2 bits together to indicate one of the functions; this is not limited here.

[0312] Example 5:

[0313] In embodiments 1-4 above, when the on-demand SSB activation signaling is used to indicate SCell activation, multiple SSB parameters can be configured for this SCell. These SSB parameters correspond to different application times. For example, two SSB cycles can be configured. Thus, SCell activation can be achieved using a single on-demand SSB activation signaling, as shown in Figure 9: the first cycle is used for SSB measurement, with a cycle of 5ms and a duration of 3; the second cycle is used for SCell activation, with a cycle of 20ms and a duration of 6. Similar to embodiment 1, this configuration of multiple SSB parameters can be achieved through pre-configuration or indicated in the activation signaling.

[0314] For example, RRC signaling is configured with two sets of parameters:

[0315] The on-demand SSB activation signaling corresponding to index 2 can be used for SCell activation. Some SSB parameters contain two values ​​(these two values ​​can be used repeatedly in series). For example, if "the number and location of SSBs in the SSB burst" contains 1001 and 0001, then 1001 can be used in the first cycle, 0001 in the second cycle, 1001 in the third cycle, and 0001 in the fourth cycle, etc. The SSB cycle and SSB duration are similar; it is similar to the scheme shown in Figure 9.

[0316] In this embodiment, SCell activation can be achieved using only one on-demand SSB activation signaling, further reducing the power consumption of the base station and the terminal.

[0317] It should be noted that the relevant content of the above embodiments can be referred to each other, and the repeated parts will not be described again.

[0318] Based on the above, the solutions provided in this disclosure involve the following:

[0319] 1. Contents of On-demand SSB activation signaling:

[0320] 1) Includes at least one of the following: SSB time index, SSB location in the burst set, pattern index of one of multiple patterns of predefined or base station configured on-demand SSB, on-demand SSB start time, SSB duration, and on-demand SSB function indication parameters.

[0321] 2) The pattern information of the on-demand SSB described in 1) can be configured independently for each cell or jointly for multiple cells. 3) Based on 1), the base station can also configure an energy-saving cell identifier for the terminal, indicating that a cell is an energy-saving cell.

[0322] 2. Correlation between On-demand SSB activation and measurement reporting:

[0323] 1) The on-demand SSB activation signaling can indicate the reporting configuration ID, triggering the reporting of this configuration.

[0324] Alternatively, 2) on-demand SSB activation signaling can implicitly trigger measurement reporting for the corresponding cell.

[0325] 3. On-demand SSB activation signaling indicates SSB function:

[0326] SSB measurement;

[0327] SCell activation;

[0328] Downlink synchronization.

[0330] The parameters are indicated by the parameters (which can be carried in the activation signaling);

[0331] By deactivating the signaling instruction;

[0332] Implicit indication through the occurrence of an event.

[0333] In summary, the embodiments of this disclosure propose an on-demand SSB transmission mechanism. By dynamically activating or deactivating SSB transmission, it is possible to enable or disable SSB transmission according to service and / or channel condition requirements, thereby achieving energy saving for base stations and terminals.

[0334] This disclosure also provides an information transmission device, which is a network device, as shown in FIG10, including a memory 101, a transceiver 102, and a processor 103.

[0335] Memory 101 is used to store computer programs; transceiver 102 is used to send and receive data under the control of processor 103; processor 103 is used to read the computer programs in memory 101 and perform the following operations:

[0336] The transceiver 102 sends a Synchronization Signal Block (SSB) transmission signaling to the terminal. The SSB transmission signaling includes a first signaling, which is used to trigger the transmission of the SSB; or, the first signaling is used to trigger the transmission of the SSB and to stop the transmission of the SSB; or, the SSB transmission signaling includes a second signaling and a third signaling, whereby the second signaling is used to trigger the transmission of the SSB and the third signaling is used to stop the transmission of the SSB.

[0337] The SSB transmission signaling carries the transmission parameter information of the SSB.

[0338] The information transmission device provided in this embodiment sends a Synchronization Signal Block (SSB) transmission signaling to a terminal. The SSB transmission signaling includes a first signaling signal used to trigger SSB transmission, or the first signaling signal used to both trigger and stop SSB transmission; or the SSB transmission signaling includes a second and a third signaling signaling signaled, the second signaling signaled to trigger SSB transmission, and the third signaling signaled to stop SSB transmission. The SSB transmission signaling carries SSB transmission parameter information. This supports dynamically activating or deactivating SSB transmission, thereby avoiding energy waste caused by continuous SSB transmission, reducing SSB transmission energy consumption, achieving energy saving for network devices and terminals, and solving the problem of high SSB transmission energy consumption in related technologies.

[0339] Specifically, transceiver 102 is used to receive and send data under the control of processor 103.

[0340] In Figure 10, the bus architecture may include any number of interconnected buses and bridges, specifically linking various circuits of one or more processors represented by processor 103 and memory represented by memory 101. The bus architecture may also link various other circuits such as peripheral devices, voltage regulators, and power management circuits, which are well known in the art and therefore will not be described further herein. The bus interface provides an interface. Transceiver 102 may be multiple elements, including transmitters and receivers, providing units for communicating with various other devices over transmission media, including wireless channels, wired channels, optical fibers, etc. Processor 103 is responsible for managing the bus architecture and general processing, and memory 101 may store data used by processor 103 during operation.

[0341] The processor 103 can be a central processing unit (CPU), an application-specific integrated circuit (ASIC), a field-programmable gate array (FPGA), or a complex programmable logic device (CPLD). The processor can also adopt a multi-core architecture.

[0342] The transmission parameter information includes at least one of the following: SSB time index information; SSB location information in the burst set; index of a pattern in a predefined or network device configured SSB pattern; SSB start time information; SSB duration information; and SSB function indication parameters.

[0343] In some embodiments, the pattern of the SSB is configured for at least one cell.
