Description

Technical Field

[0001] The present application relates to the field of wireless communication technology, and in particular to a signaling indication method and device. Background Art

[0002] 5G was designed to meet the growing traffic demand while limiting the power consumption of mobile networks. With the launch of 5G Advanced, network energy saving has received increasing attention. Release 18 defines a network energy consumption model to identify opportunities to improve network energy efficiency and specifies methods so that base stations can dynamically adjust the active part of their antennas and the transmit power. Based on Release 18, Release 19 will further introduce additional energy saving features, including: on-demand SSB transmission in secondary cells and on-demand SIB1 transmission for idle UEs. The SIB1 information of traditional base stations is periodically sent along with the broadcast information. The UE will start the system message acquisition process after cell selection (such as power on), cell reselection, intra-system handover completion, reconfiguration from synchronization, entering 5G RAT from other RATs, and returning to coverage from non-coverage areas. From the perspective of energy saving, even if the terminal does not need to obtain broadcast information, SIB1 information is still being sent. Especially for terminals in the IDLE state, it is possible to consider requesting SIB1 information transmission on demand during the terminal's cell reselection process.

[0003] For on-demand SIB1 transmission for idle UEs, the energy-saving terminal receives the configuration information of the uplink wake-up signal (ULWUS) from the anchor cell (anchor cell, cellA). The energy-saving terminal sends the uplink wake-up signal to the energy-saving cell (NESCELL) according to the configuration information, and then receives the broadcast signal of the on-demand SIB1 from the energy-saving cell. The specific process is as follows: 1. The anchor cell configures the terminal with uplink wake-up signaling, which includes information such as the search space and time-frequency resources of the on-demand SIB1 (on demandSIB1) of the receiving energy-saving cell.

[0004] 2. The energy-saving terminal receives the uplink wake-up signal configuration information from the anchor cell. When it needs to receive the on-demand SIB1, it sends the uplink wake-up signal to the energy-saving cell. After the energy-saving cell sends a response (RAR response), it sends SIB1 according to the uplink wake-up signal configuration. The terminal receives the on-demand SIB1 according to the search space information and other information configured in the uplink wake-up signal.

[0005] Problems to be solved: Before the NES terminal sends information requesting SIB1, the energy-saving cell may be broadcasting SIB1 periodically. Before requesting on-demand SIB1, the NES terminal needs to blindly search whether the energy-saving cell is sending SIB1 based on the configuration information of the uplink wake-up signal. If the energy-saving cell is periodically sending broadcast information SIB1 at this time, the energy-saving terminal can directly receive the SIB1 sent by the energy-saving cell based on the received uplink wake-up signal configuration information, without sending an uplink wake-up signal to request on-demand SIB1. However, if the energy-saving cell does not send SIB1, the energy-saving terminal cannot search for the SIB1 information of the energy-saving cell. The energy-saving terminal still needs to send a wake-up signal to request on-demand SIB1, which will increase the terminal power and complexity and increase the delay in obtaining SIB1.

[0006] When the uplink wake-up configuration information of the energy-saving cell is updated, signaling is required to indicate the new update information to the terminal. If only the uplink wake-up signal configuration signaling is used for updating, considering that the uplink wake-up signal contains the uplink wake-up information of multiple energy-saving cells, even if the uplink configuration information of a certain energy-saving cell is updated, the anchor cell needs to rebroadcast the updated uplink wake-up signal configuration information of all energy-saving cells to the terminal so that the terminal can request on-demand SIB1. Therefore, the anchor cell needs to frequently update the SIB broadcast information to update the configuration of the uplink wake-up signal, which brings unnecessary signaling overhead and increases the power consumption and signaling overhead of the anchor cell. Summary of the invention

[0007] The present application proposes a signaling indication method and device, which solves the problems of long latency for a terminal to obtain on-demand SIB1 and high power consumption and signaling overhead for an anchor cell to send uplink new signal configuration information, and is particularly suitable for terminal communication scenarios in which energy-saving cells and anchor cells of a mobile communication network collaborate.

If the first signaling indicates that the energy-saving terminal in the energy-saving cell will broadcast SIB1 periodically within a certain period of time, then the energy-saving terminal in the cell does not need to send a wake-up signal during this period, and can directly receive the SIB1 information of the energy-saving cell, thereby avoiding invalid transmission of the uplink wake-up signal. If the first signaling indicates that the energy-saving terminal in the energy-saving cell is not sending broadcast information SIB1, then the energy-saving terminal in the cell needs to send an uplink wake-up signal according to the configuration information of the uplink wake-up signal, triggering the energy-saving cell to send on-demand SIB1, and will indicate to the terminal in the cell in the first signaling that the energy-saving cell is broadcasting and sending SIB1, thereby avoiding the terminal from checking whether it can receive SIB1 before sending the wake-up signal, thereby improving the timeliness of receiving SIB1 and reducing the power consumption of the terminal. If the first signaling indicates that the uplink configuration information of a certain energy-saving cell is updated, the terminal sends an uplink wake-up signal according to the updated uplink wake-up signal configuration information, thereby avoiding frequent updates of the uplink wake-up signal configuration information and reducing signaling redundancy and base station power consumption.

DETAILED DESCRIPTION

[0023] In order to make the purpose, technical solution and advantages of the present application clearer, the technical solution of the present application will be clearly and completely described below in combination with the specific embodiments of the present application and the corresponding drawings. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present application.

[0024] The technical solutions provided by various embodiments of the present application are described in detail below in conjunction with the accompanying drawings.

[0025] Figure 1 This is a flow chart of an embodiment of the method of the present application. According to the embodiments of the first aspect and the second aspect, the working process of the present application is as follows 110 to 130: Step 110: The network side device determines the timing for the target energy-saving cell to send broadcast information, and sends first indication information indicating whether the target energy-saving cell currently sends broadcast information and / or second indication information indicating whether the target energy-saving cell updates wake-up signal configuration information.

[0026] In one embodiment of the present application, the network side device belongs to an anchor cell, and the first signaling includes the first indication information and / or the second indication information; the first signaling is at least one of the following: paging message, downlink control information, and configuration information of an uplink wake-up signal.

[0027] In another embodiment of the present application, the network side device belongs to a target energy-saving cell, and the second signaling includes the first indication information and / or the second indication information; and the second signaling is a downlink control signaling.

[0028] In one embodiment of the present application, the first indication information further includes a timing for the target energy-saving cell to send broadcast information.

[0029] In the embodiment of the present application, the broadcast information of the target energy-saving cell refers to SIB1. However, it should be noted that those skilled in the art can understand that after waking up the target energy-saving cell, the information sent by the target energy-saving cell can be any broadcast information, and the solution of the present application can be applicable.

[0030] Step 120: The terminal side device receives a first signaling from an anchor cell and / or a second signaling from a target energy-saving cell.

[0031] In an embodiment of the present application, the first signaling and / or the second signaling includes first indication information indicating whether the target energy-saving cell is currently sending broadcast information.

[0032] In one embodiment of the present application, the first signaling and / or the second signaling further includes second indication information on whether the target energy-saving cell updates the wake-up signal configuration information.

[0033] Step 130: The terminal device determines to receive broadcast information or send an uplink wake-up signal in response to the first indication information.

[0034] In one embodiment of the present application, in response to the second indication information, the wake-up signal configuration information is updated, and a wake-up signal is sent to the target energy-saving cell.

[0035] In one embodiment of the present application, the first indication information further includes a timing for the target energy-saving cell to send broadcast information, and the terminal side device responds to the first indication information, and any terminal side device receives the broadcast information according to the timing.

[0036] Through the above technical solution, the energy-saving terminal in the energy-saving cell receives the wake-up signal configuration information from the anchor cell, receives the first signaling from the anchor cell and / or the second signaling from the target energy-saving cell, which indicates whether the target energy-saving cell sends broadcast information and / or whether the wake-up signal information of the energy-saving cell is updated. The terminal sends an uplink wake-up signal according to the wake-up signal configuration information and the first and second signaling to obtain the SIB1 broadcast information of the energy-saving cell. When the terminal receives the first signaling or the second signaling indicating that the energy-saving cell is sending broadcast information, the terminal does not need to send an uplink wake-up signal and receives the SIB1 broadcast information from the energy-saving cell. Furthermore, the first and second signaling can instruct the terminal that the target energy-saving cell sends broadcast information within the first time.

[0037] It should be noted that the above steps are used for network entities of a wireless communication system, including terminal side devices, network side devices or other intermediate devices; the above steps can also be used for service devices that provide information processing for the network entity devices; the above steps can also be used for any device, system, subsystem, circuit, chip or software entity that provides information reception, transmission, identification and processing for terminal side devices or network side devices.

[0038] Figure 2 This is a flowchart of an embodiment of the method of the present application including first indication information.

[0039] Embodiment 1: The terminal receives the wake-up signal configuration information from the anchor cell and receives the first signaling. If the first signaling indicates that the energy-saving cell is not sending broadcast information, the terminal sends an uplink wake-up signal according to the wake-up signal configuration information. If the first signaling indicates that the energy-saving cell is sending broadcast information, the terminal does not need to send an uplink wake-up signal.

[0040] The specific process is as follows: Step 210: The terminal receives the wake-up signal configuration information from the anchor cell. The configuration information includes information such as time-frequency resources required for the terminals of multiple energy-saving cells to send wake-up signals, and also includes information such as the search space for the terminal to receive on-demand SIB1.

[0041] Step 220: The terminal receives a first signaling from the anchor cell, where the first signaling indicates that the target energy-saving cell does not send any broadcast information.

[0042] The target energy-saving cell is any one of the energy-saving cells.

[0043] The first signaling can be in the following ways: 1) The energy-saving terminal receives the first signaling as the configuration information of the uplink wake-up signal, that is, the configuration information sent to the terminal indicates whether the energy-saving cell is sending periodic SIB1. The energy-saving terminal determines whether to send an uplink wake-up signal based on the received uplink wake-up signal configuration information, and further triggers the sending of an uplink wake-up signal to request on-demand SIB1. When the target energy-saving cell sends periodic SIB1, the uplink wake-up signal configuration information of the energy-saving cell is no longer sent to the terminal.

[0044] The problem with this method is that, because the uplink wake-up signal is broadcast and sent in the SIB information of the anchor cell, and the uplink wake-up signal contains uplink wake-up information of multiple energy-saving cells, if the SIB1 sending status of the target energy-saving cell is indicated in the uplink wake-up signal configuration information, even if a certain energy-saving cell needs to indicate that there is broadcast information to be sent, or the uplink configuration information of a certain energy-saving cell is updated, the anchor cell needs to resend the updated uplink wake-up signal configuration information to the terminal through the SIB, so that the terminal can request on-demand SIB1 from the target energy-saving cell. Therefore, the anchor cell will frequently update the SIB broadcast information to update the configuration of the uplink wake-up signal, which will bring unnecessary signaling overhead and increase the power consumption of the anchor cell and the energy-saving cell.

[0045] 2) When the energy-saving terminal is in an IDLE state or an unconnected state, the energy-saving terminal receives the first signaling as a paging signaling, and adds the update status and update information of the uplink wake-up signal configuration information, or an indication of whether to send an uplink wake-up signal, to the paging signaling.

[0046] It should be noted that the "indication of whether an uplink wake-up signal needs to be sent" in this application is the "indication of whether the target energy-saving cell sends broadcast information" included as the first indication information. Those skilled in the art can understand that in the application scenario of this application, when the network side device of the target energy-saving cell sends broadcast information, the energy-saving terminal can receive it without sending an uplink wake-up signal. Conversely, when the network side device of the target energy-saving cell does not send broadcast information, the energy-saving terminal needs to send an uplink wake-up signal.

[0047] The workflow of the energy-saving terminal is: (1) The energy-saving terminal in IDLE state searches for SSB and obtains the uplink wake-up signal configuration information in the broadcast information SIB of the anchor cell.

[0048] (2) The energy-saving terminal in the IDLE state receives a paging message on the paging channel and obtains the first signaling, thereby obtaining an indication of whether an uplink wake-up signal needs to be sent. This information is used to wake up the energy-saving cell, etc.

[0049] The working process of the anchor cell and the energy-saving cell is as follows: when the system information changes (including the uplink wake-up signal configuration information), the anchor cell will send a system information change indication SI change indication in the paging message to the terminal, adding indication information. When the terminal receives this indication, it can know that the target energy-saving cell is sending SIB1, and can directly receive SIB1 without sending an uplink wake-up signal to obtain it.

[0050] 3) When the terminal has accessed the anchor cell, the energy-saving terminal receives the first signaling as a downlink control signaling, and adds the update status and update information of the uplink wake-up signal to the downlink control signaling, or an indication of whether an uplink wake-up signal needs to be sent. The energy-saving cell sends downlink control signaling to the terminal in the cell, and preferably public control information indicates to all terminals that SIB1 is being sent. Specifically, information can be added to the downlink public control signaling encrypted with SI-RNTI to indicate to the terminal whether each energy-saving cell is sending broadcast SIB1. For example, the SIB1 sending status of the corresponding energy-saving cell can be indicated in a bitmap manner, or in a codeword manner, through N bits, to indicate the SIB1 sending status of 2 to the power of N energy-saving cells.

[0051] Step 230, the terminal receives the first signaling. If the first signaling indicates that the energy-saving cell is sending SIB1, the terminal receives SIB1 according to the uplink wake-up signal configuration (uplink wake-up signal) information. If the first signaling indicates that the energy-saving cell is not sending SIB1, step 240, the terminal sends an uplink wake-up signal.

[0052] Step 250: The energy-saving cell sends a second signaling to indicate to other energy-saving terminals that the network-side device of the cell is sending SIB1. The indication information of the second signaling can be used as indication information for other energy-saving terminals whether to send an uplink wake-up signal.

[0053] Figure 3 This is a flow chart of an embodiment of the method of the present application that includes second indication information.

[0054] Embodiment 2: The terminal receives the wake-up signal configuration information from the anchor cell as the first signaling indicating that the target energy-saving cell has updated the wake-up signal configuration information, and the terminal sends an uplink wake-up signal according to the updated wake-up signal configuration information. In particular, the wake-up signal configuration information update here may also include indication information on whether a certain target energy-saving cell is sending SIB1.

[0055] The specific process is as follows: Step 310: The terminal receives the wake-up signal configuration information from the anchor cell. The configuration information includes information such as time-frequency resources for terminals in multiple energy-saving cells to send wake-up signals, and also includes information such as search space for the terminal to receive on-demand SIB1.

[0056] Step 320: The terminal receives a first signaling from the anchor cell, where the first signaling indicates whether the target energy-saving cell has updated the wake-up signal configuration information.

[0057] In this embodiment, combined with the uplink wake-up signal configuration information update indication in the SIB; preferably, the "indication of whether the target energy-saving cell updates the wake-up signal configuration information" contained in the second indication information does not refer to the updated configuration information itself. For example, the second indication information indicates whether it is updated through a status symbol, or the second indication information may include the target energy-saving cell identifier where the uplink wake-up signal configuration information is updated, and the target energy-saving cell identifier may be sent through the first signaling instead of all the configuration information. This can save signaling overhead.

[0058] In this embodiment, the first signaling has the following modes: 1) When the energy-saving terminal is in an IDLE state or an unconnected state, the energy-saving terminal receives the first signaling as a paging signaling, and adds the update status and update information of the configuration information required for the uplink wake-up signal to the paging signaling, or an indication of whether to send an uplink wake-up signal.

[0059] The workflow of the energy-saving terminal is: (1) The energy-saving terminal in IDLE state searches for SSB and obtains the uplink wake-up signal configuration information in the broadcast information SIB of the anchor cell.

[0060] (2) The energy-saving terminal in IDLE state receives a paging message on the paging channel and obtains the first signaling, and then obtains the updated information of the uplink wake-up signal configuration, and uses this information to wake up the energy-saving cell, etc. Alternatively, the terminal obtains the first signaling to determine which specific target energy-saving cell has an updated uplink wake-up signal configuration, and the terminal searches the SSB of the anchor cell again based on this information to obtain the updated uplink wake-up signal configuration information of the corresponding target energy-saving cell, without having to re-obtain the uplink wake-up signal configuration information of all energy-saving cells.

[0061] The working process of the anchor cell and the energy-saving cell is as follows: the anchor cell sends the configuration information of the uplink wake-up signal in the broadcast signaling in the SSB. When the system information changes (including the uplink wake-up signal configuration information), the anchor cell network will send the system information change indication SI change indication in the paging message to the terminal, as the second indication information indicating which energy-saving cell's uplink wake-up signal has been updated, and the specific update information. The terminal sends the uplink wake-up signal according to the updated uplink configuration information to obtain the on-demand SIB1. Or the anchor cell indicates which specific energy-saving cells have been updated when the system information changes, and only sends the uplink wake-up signal configuration information corresponding to these energy-saving cells in the subsequent broadcast signaling.

[0062] 2) When the terminal has accessed the anchor cell, the energy-saving terminal receives the first signaling as downlink control signaling. As an embodiment, the second indication information in the downlink control signaling may also include the update status and update information of the target energy-saving cell for the uplink wake-up signal configuration information.

[0063] The energy-saving cell sends a second signaling (downlink control signaling) to the terminal in the cell, preferably using public control information to indicate to all terminals that their network-side devices are sending SIB1. Specifically, the second signaling can also add information to the downlink public control signaling encrypted with SI-RNTI to indicate the updated uplink wake-up signal configuration information of each energy-saving cell to the terminal. For example, a codeword can be used to indicate which of the 2 to the power of N energy-saving cells have updated uplink wake-up signal information through N bits, and then use M bits to indicate which content has been updated.

[0064] Step 330: When the terminal receives the first signaling from the anchor cell or the second signaling from the target energy-saving cell, the terminal sends an uplink wake-up signal according to the updated uplink wake-up signal configuration information.

[0065] Step 340: Receive SIB1 according to the updated uplink wake-up signal configuration information indicated by the first signaling or the second signaling.

[0066] In the embodiment of step 3, compared with the above-mentioned embodiment, the first signaling and / or the second signaling further includes updated uplink wake-up signal configuration information.

[0067] Figure 4 This is a flow chart of an embodiment in which the first indication information in the method of the present application includes the timing of sending broadcast information.

[0068] Embodiment 3: The terminal receives the wake-up signal configuration information from the anchor cell, the terminal sends an uplink wake-up signal according to the wake-up signal configuration information, and receives the first signaling, which indicates to the terminal that the target energy-saving cell sends broadcast information within the first time, that is, it indicates that the terminal does not need to send an uplink wake-up signal. The specific process is as follows: Step 410: The terminal receives the wake-up signal configuration information from the anchor cell. The configuration information includes information such as time-frequency resources for terminals in multiple energy-saving cells to send wake-up signals, and also includes information such as search space for the terminal to receive on-demand SIB1.

[0069] Step 420: The terminal receives a first signaling from the anchor cell, wherein the first indication information indicates whether the energy-saving cell sends broadcast information, and further indicates that the broadcast information is sent within the first time.

[0070] The first signaling has the following modes: 1) The energy-saving terminal receives the first signaling as uplink wake-up signal configuration information, that is, the configuration information sent to the terminal indicates whether the energy-saving cell is sending periodic SIB1 and the sending time is within the first time. The energy-saving terminal determines at what time to send the uplink wake-up signal to trigger the sending of the request SIB1 according to the received uplink wake-up signal configuration information.

[0071] 2) When the energy-saving terminal is in an IDLE state or an unconnected state, the energy-saving terminal receives the first signaling as a paging signaling, and adds an indication of whether an uplink wake-up signal needs to be sent within the first time to the paging signaling.

[0072] The workflow of the energy-saving terminal is: (1) The energy-saving terminal in IDLE state searches for SSB and obtains the uplink wake-up signal configuration information in the broadcast information SIB of the anchor cell.

[0073] (2) The energy-saving terminal in IDLE state receives a paging message on the paging channel and obtains the first signaling, and can obtain whether the wake-up signal has broadcast information sent within the first time. If not, it initiates the wake-up of the energy-saving cell to obtain the on-demand SIB1.

[0074] The working process of the anchor cell and the energy-saving cell is as follows: when the network system information of the anchor cell changes (including the uplink wake-up signal configuration information), the system information change indication SI change indication in the paging message will be sent to the terminal, and the indication information will be added to instruct the energy-saving cell to send SIB1 as soon as possible.

[0075] 2) When the terminal has accessed the anchor cell, the energy-saving terminal receives the first signaling as a downlink control signaling, and adds the update status and update information of the uplink wake-up signal to the downlink control signaling, or indicates whether the uplink wake-up signal needs to be sent within the first time. The energy-saving cell sends downlink control signaling to the terminal in the cell, and preferably public control information indicates to all terminals that SIB1 is being sent. Specifically, information can be added to the downlink public control signaling encrypted with SI-RNTI to indicate to the terminal whether each energy-saving cell is sending broadcast SIB1. For example, the SIB1 sending status of the corresponding energy-saving cell can be indicated in a bitmap manner, or in a codeword manner, through N bits, to indicate the SIB1 sending status of 2 to the power of N energy-saving cells, and M bits are added to indicate the corresponding first time.

[0076] Step 430: The terminal receives the first signaling. If the first signaling indicates that the target energy-saving cell is not currently sending SIB1, and the terminal device determines that uplink wake-up information needs to be sent, the uplink wake-up information is sent to the target energy-saving cell.

[0077] Step 440, the terminal receives the first signaling. If the first signaling indicates that the target energy-saving cell sends SIB1 within the first time, and the terminal device determines that there is no need to send uplink wake-up information, the terminal receives SIB1 within the first time according to the uplink wake-up signal configuration (uplink wake-up signal) information.

[0078] Step 450: When the terminal triggers the energy-saving cell to send the on-demand SIB1, the energy-saving cell sends a second signaling to indicate to other energy-saving terminals that the energy-saving cell is sending SIB1 within the first time.

[0079] It should be noted that the above embodiments of the present application are not all embodiments. For example, if the terminal identifies or accesses the target energy-saving cell, the first indication information and / or the second indication information can be included in the second signaling of the target energy-saving cell. In this way, the first indication information can include not only an indication of whether to send broadcast information, but also an indication of the timing of sending the broadcast information, and further determine the response of the terminal side device after receiving the second signaling.

[0081] To implement the above technical solution, the present application proposes a network side device 500, which includes a network sending module 501, a network determining module 502, and a network receiving module 503 that are interconnected.

[0082] The network sending module is used to send the first signaling or the second signaling. When the network side device belongs to the anchor cell, the network sending module also sends the uplink wake-up signal configuration information of multiple energy-saving cells in a broadcast manner; when the network side device belongs to the target energy-saving cell, the network sending module is also used to send the broadcast information SIB1.

[0083] The network determination module is used to determine the timing for the target energy-saving cell to send broadcast information, and can also determine whether the target energy-saving cell changes the uplink wake-up signal configuration information.

[0084] The network receiving module is used to receive an uplink wake-up signal when the network side device belongs to the target energy-saving cell.
