Description

Information transmission method, device and equipment

[0001] This disclosure claims priority to the Chinese patent application filed with the China Patent Office on February 19, 2024, with application number 202410184894.8 and application name “A method, device and apparatus for information transmission,” the entire contents of which are incorporated herein by reference. Technical Field

[0002] The present disclosure relates to the field of communication technologies, and in particular to an information transmission method, apparatus, and device. Background Art

[0003] The synchronization signal block (Synchronization Signal / PBCH Block, SSB) in the current system is a periodic signal. The number and position of each SSB are indicated by the position of the SSB in the burst set (ssb-PositionsInBurst). In the carrier aggregation (CA) scenario, the SSB configuration of the primary cell (PCell) is sent through the system information block (SIB) 1, and the SSB configuration of the secondary cell (SCell) is sent separately for each SCell through the radio resource control (RRC). After that, the base station always transmits SSB according to the configuration; at the same time, in order to ensure coverage within the cell, SSBs in multiple directions may be used for beam scanning transmission. This may lead to scenarios where unnecessary SSB transmission may exist, resulting in high energy consumption of the network and the terminal.

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

[0210] The terminal device involved in the embodiments of the present disclosure may be a device that provides voice and / or data connectivity to a user, a handheld device with wireless connection function, or other processing device connected to a wireless modem. In different systems, the name of the terminal device may also be different. For example, in a 5G system, the terminal device may be called User Equipment (UE). A wireless terminal device can communicate with one or more core networks (CN) via a radio access network (RAN). The wireless terminal device may be a mobile terminal device, such as a mobile phone (or "cellular" phone) and a computer with a mobile terminal device. For example, it may be a portable, pocket-sized, handheld, computer-built-in or vehicle-mounted mobile device that exchanges voice and / or data with a radio access network. For example, personal communication service (PCS) phones, cordless phones, session initiation protocol (SIP) phones, wireless local loop (WLL) stations, personal digital assistants (PDAs), and other devices.

Depending on the specific application scenario, the base station may also be called an access point, or may be a device in an access network that communicates with a wireless terminal device through one or more sectors on an air interface, or may be named by another name.

[0212] Network devices and terminal devices can each use one or more antennas for Multiple Input Multiple Output (MIMO) transmission. MIMO transmission can be single-user MIMO (SU-MIMO) or multi-user MIMO (MU-MIMO). Depending on the form and number of antenna combinations, MIMO transmission can be two-dimensional MIMO (2D-MIMO), three-dimensional MIMO (3D-MIMO), full-dimensional MIMO (FD-MIMO), or massive MIMO. It can also use diversity transmission, precoded transmission, or beamforming transmission.

[0213] The following first introduces the contents involved in the solution provided by the embodiment of the present disclosure.

[0214] Currently, SSB transmission is periodic, and base stations cannot shut down according to service needs. Furthermore, they do not consider user distribution. Even if there are no users in a certain direction, SSBs may still be transmitted in that direction. Consequently, base stations cannot dynamically adjust SSB transmission and shutdown based on actual scenario requirements. SSB parameters can only be updated through static signaling (SIB1) or RRC. This results in high network and terminal energy consumption.

[0215] Based on the foregoing, the embodiments of the present disclosure provide an information transmission method, apparatus, and device to address the high energy consumption issue of SSB transmission in the related art. The method, apparatus, and device are based on the same patent application concept. Since the principles for solving the problems in the method, apparatus, and device are similar, their implementations can refer to each other, and any repetitions will not be repeated.

[0216] The information transmission method provided in the embodiment of the present disclosure is applied to a network device, as shown in FIG2 , and includes:

[0217] Step 21: Send synchronization signal block SSB transmission signaling to the terminal, the SSB transmission signaling includes a first signaling, the first signaling 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, 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 transmission parameter information of the SSB.

[0218] In which, when "the first signaling is used to trigger the transmission of SSB", the stopping of SSB transmission can be triggered by the occurrence of a predefined event; and / or, the SSB transmission signaling can be an instruction to activate a certain SSB transmission or deactivate a certain SSB transmission, but is not limited to this.

[0219] In some embodiments, after step 21, it may also include: sending SSB according to the SSB transmission signaling, but it is not limited to this. For specific related content, please refer to the terminal side (for example, sending SSB according to the SSB transmission signaling and the following first identifier), which will not be repeated here.

The time index information of the SSB, such as SSB_index (index); and the index of the pattern can be implemented as an index of the parameter set of the SSB. For details, please refer to the content in the following embodiments and will not be repeated here.

[0223] In some embodiments, the information transmission method further includes: sending a first identifier to the terminal, the first identifier being used to indicate that the first cell is an energy-saving cell. This can further support energy conservation of network devices and terminals. The first cell can be any cell, or a cell that meets the conditions, and is not limited here.

[0224] At least one of the first signaling, the second signaling, and the third signaling is further used to trigger the terminal to report measurement results.

[0274] It is noted here that the above-mentioned related contents on the base station side and the terminal side can refer to each other, and the repeated contents will not be repeated.

[0275] The following is a specific example of the solution provided in the embodiment of the present disclosure.

[0276] Example 1:

[0277] Assume that the base station needs to activate the SCell for the terminal based on the current downlink service transmission requirements. In one embodiment, the base station will activate all unactivated SCells for the terminal. In the New Radio (NR) protocol, the SCell of the terminal is numbered together with the PCell using the ServingCellIndex and configured to the UE. In this embodiment, it is assumed that two SCells are activated for the terminal, and the numbers are represented as ServingCell_index1 and ServingCell_index2. At the same time, it is assumed that these two SCells do not transmit SSB before activation, that is, the base station cannot obtain the channel quality of the SCell. In one embodiment, the base station can configure energy-saving cell identifiers for ServingCell_index1 and ServingCell_index2 respectively, indicating that they do not transmit SSB before activation. In this way, ServingCell_index1 and ServingCell_index2 are both unknown cells (for example, cells that the UE has not measured for a period of time, but not limited to this).

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

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

[0280] The number and position of SSBs in an SSB burst (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 indicates the length of time after SSB activation, after which transmission ceases; it can be expressed as the number of transmission cycles or a time length (such as milliseconds or seconds). The SSB start time can be based on the time of receipt of the activation signaling as the reference point, indicating the offset time relative to this reference point, such as the offset symbol, subframe, millisecond, etc.; it can also be determined by the reserved position of the SSB transmission, for example, defined as starting from a reserved position after receipt of 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 in 4 ways, as shown in the following table:

[0288] The SSB duration 3 may indicate that it lasts for 3 cycles; the SSB start time 1 may indicate the SSB time domain position reserved according to the cycle, and transmission begins at the first reserved time domain position after receiving the activation signaling.

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

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

[0291] In another embodiment, multiple or all SCells may be indicated to share a parameter index, for example, indicating an on-demand SSB parameter set index of 4, which is used for both ServingCell_index1 and ServingCell_index2. For scenarios where multiple SCells share a parameter index, the specific SCells sharing the parameter index may be determined by protocol agreement. For example, the protocol may stipulate that SCells configured in the same simultaneous update list (e.g., simultaneousU-TCI-UpdateList1-r17 (Simultaneous Transmission Configuration Indication Update) list) share a parameter.

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

[0293] Afterwards, the base station sends an SCell activation signaling, and the SCell activation signaling may include an activation indication field of the corresponding SCell (which may carry an activation status indication). In one embodiment, the SCell activation signaling may also include an SSB activation indication in the SSB burst set of the corresponding SCell (this indication may notify the UE of the SSB to be transmitted and actually activate the SSB transmission), which may be used to indicate that one or several SSBs in the SSB burst set are activated for transmission. The specific determination of which SSB is activated for transmission may be determined by the base station based on the acquired terminal location information, or the result report of the on-demand SSB measurement by the above-mentioned terminal; 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 the indication with new information such as the SSB activation signaling. The SSB activation indication may be indicated by a bitmap (such as using the number and position of the SSB in the above-mentioned SSB burst set to indicate), or may be indicated by an SSB index (corresponding to the time index information of the above-mentioned SSB); for example, a bitmap indication is used, as shown in the following table:

[0294] Among them, 0001 means that for ServingCell_index1, its SSB burst set contains 4 possible SSBs, and only the fourth SSB is activated for transmission. 0100 means that for ServingCell_index2, its SSB burst set contains 4 possible SSBs, and only the second SSB is activated for transmission. The SCell activation signaling may also include the SSB start time. Starting from the start time, the base station will send the fourth SSB on ServingCell_index1 according to the SSB period configured by RRC; and send the second SSB on ServingCell_index2 according to the SSB period configured by RRC; until the terminal receives the SCell deactivation signaling, the base station will stop sending the SSB (specifically, the base station may send a deactivation instruction and then stop sending the SSB, but is not limited to this). The RRC configuration here can adopt the configuration method in the current protocol, and independently configure parameters such as the SSB period under each ServingCell. In one embodiment, the SCell deactivation signaling may also include an SSB deactivation indication in the SSB burst set of the corresponding SCell (this indication may notify the UE to stop transmitting the SSB and actually deactivate the SSB transmission), which is used to indicate that one or several SSBs in the SSB burst set are to be deactivated for transmission.

[0295] The operating process of this embodiment is shown in Figure 4 (where on-demand SSB-1 represents the SSB activated for measurement by on-demand SSB activation signaling, on-demand SSB-2 represents the SSB activated by SCell activation signaling, and the dashed box represents the SSB not transmitted). After an on-demand SSB activation, the terminal performs measurements (L1 / L3 (Layer 1 or Layer 3) measurements), converting an unknown SCell into a known SCell. In subsequent SCell activation, faster activation is achieved, shortening the SCell activation time.

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

[0297] Example 2:

[0298] Assume that the base station needs to add or delete an SCell. Since there is no SSB transmission on the SCell to be added or deleted, the base station needs to trigger on-demand SSB for measurement; then, based on the measurement result report, the base station determines whether to add or delete the SCell. On the basis of the on-demand SSB activation signaling described in Example 1, the on-demand SSB activation signaling may also indicate measurement reporting configuration information (such as the above-mentioned reporting configuration ID), or the activation signaling may implicitly associate the reporting configuration information. For example, for ServingCell_index1, the base station configures multiple reporting configurations for the terminal. In this embodiment, it is assumed that there are two reporting configurations, represented as report configuration (ReportConfig)-1 and ReportConfig-2 (or measurement identifier (MeasID)-1 and MeasID-2); then in the on-demand SSB activation signaling, it may be explicitly indicated whether the corresponding reporting configuration is ReportConfig-1 or ReportConfig-2. Afterwards, the terminal performs on-demand SSB measurement according to the reporting configuration, and reports the measurement result according to the format in ReportConfig-1 or ReportConfig-2.

[0299] Another implementation is to instruct, in the on-demand SSB activation signaling, corresponding to the SCell, only whether to report the measurement results. As shown in the following table, ServingCell_index1 is instructed to report the measurement results, while ServingCell_index2 is not instructed to report the measurement results.

[0300] In addition, in another embodiment, reporting can be performed in an implicitly associated manner. For example, for the measurement report of a certain cell configured in the mobility management process, when the on-demand SSB activation signaling indicates the on-demand SSB activation transmission of this cell, the measurement report configured by the Radio Resource Management (RRM) automatically takes effect. Afterwards, the terminal will report the result of the measurement report configured by the measurement object (MeasObject) corresponding to this cell (which can be understood as reporting according to the parameter configuration corresponding to the cell (such as indicating how to measure, how to report, etc.)). For example, in the RRM configuration, the base station configures the measurement reporting method of cell 0 (i.e., physical cell identifier PCID=0) through MeasObject. When on-demand SSB activates the on-demand SSB transmission of cell 0, the terminal will report according to the measurement configured by MeasObject.

[0301] The workflow in this embodiment is as shown in FIG6 . Since measurement reporting is performed only when on-demand SSB transmission is triggered, the power consumption of the base station and the terminal is reduced.

[0302] In addition, the solution in Example 2 can be used in combination with Example 1, which is not limited here.

[0303] Example 3:

[0304] In Example 1, on-demand SSB activation and SCell activation are indicated using different signaling. In this embodiment, the same signaling indication can be used. For example, on-demand SSB activation signaling is used. For example, for on-demand SSB used for measurement (corresponding to on-demand SSB-1 in Figure 7), the activation signaling (such as On-demand SSB activation-1) indicates that the SSB duration is 3. For on-demand SSB for SCell activation (corresponding to on-demand SSB-2 in Figure 7), the activation signaling (such as On-demand SSB activation-2) indicates that the SSB duration is 6. In this way, no additional deactivation signaling is required to indicate deactivation after SCell activation.

[0305] In another embodiment, the SSB duration parameter may not be indicated in the on-demand SSB activation signaling. Specifically, as shown in FIG8 , one approach is to use on-demand SSB deactivation signaling (e.g., On-demand SSB Deactivation-1) to instruct the SSB to stop transmission. The on-demand SSB deactivation signaling may be the same as the SCell deactivation signaling (e.g., On-demand SSB Deactivation-2) described in Example 1, or may be the same as the on-demand SSB activation signaling, for example, only changing the activation status indication from 1 to 0.

[0306] In another implementation, the transmission of the SSB may be stopped according to a change in an event, such as the addition, deletion, or modification of an SCell, or the reporting of CSI by a 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). For example, the SSB function indication field indicates that the SSB is used for one of the following functions:

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

[0309] SCell activation;

[0310] Downlink synchronization.

[0311] For example, each ServingCell uses 2 bits to indicate one of its functions, or multiple ServingCells or all ServingCells use 2 bits to indicate one of its functions, which is not limited here.

[0312] Example 5:

[0313] For the above-mentioned embodiments 1-4, 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 are configured. In this way, SCell activation can be achieved using one 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, the configuration of multiple SSB parameters can be achieved through pre-configuration or indicated in the activation signaling.

[0314] For example, RRC signaling configures two parameter sets:

[0315] The on-demand SSB activation signaling corresponding to index 2 can be used for SCell activation, where some SSB parameters contain two values ​​(these two values ​​can be used repeatedly in series). For example, if the "number and position of SSBs in the SSB burst set" 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 also similar; it is similar to the scheme shown in Figure 9.

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

[0317] It is to be noted that the relevant contents of the above embodiments can be referred to each other, and the repeated parts will not be repeated here.

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

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