It is understood that the aforementioned functional modules can be network elements in hardware devices, software functional modules running on dedicated hardware, or virtualized functional modules instantiated on a platform (e.g., a cloud platform).
[0039] The method for transmitting control information provided in this application will be described in detail below with reference to the accompanying drawings, through some embodiments and application scenarios.
[0040] like Figure 2 As shown, this application embodiment provides a method 200 for transmitting control information. This method can be executed by a terminal; in other words, it can be executed by software or hardware installed on the terminal. The method includes the following steps.
[0041] S202: The terminal determines the target receiving mode; wherein the terminal supports at least two receiving modes, the at least two receiving modes including the target receiving mode, the receiving mode being used to receive control information, the control information including paging messages and / or low-power wake-up signals.
[0042] In this embodiment, the terminal can determine the receiving mode to be used, i.e., the target receiving mode, from at least two receiving modes it supports; and receive control information according to the determined target receiving mode, such as receiving paging messages according to the target receiving mode, receiving low-power wake-up signals according to the target receiving mode, and receiving both paging messages and low-power wake-up signals according to the target receiving mode.
[0043] In various embodiments of this application, the at least two receiving modes correspond to different communication bandwidths, or different receivers (e.g., power), or different number of receptions, or different types of low-power receivers are used.
[0044] In one embodiment, the at least two receiving modes correspond to receiving the control information using different communication bandwidths, such as using a broadband communication mode to receive the control information and using a narrowband communication mode to receive the control information, in order to improve the performance of the terminal and the network side.
[0045] For example, for a mobile phone, supporting narrowband communication mode on top of broadband communication mode might not significantly increase cost or complexity. However, in certain situations (such as areas with poor broadband coverage), the additional coverage provided by narrowband cells can ensure basic communication. Furthermore, broadband cells may enter a dormant mode based on dynamic changes in services. When a terminal wants to camp on such a cell, it needs to wake it up first. If the terminal can camp on a narrowband cell, it doesn't need to frequently wake up the dormant broadband cell due to mobility, thus improving network and terminal energy efficiency. When the terminal's service needs to be met, it can then access the broadband cell.
[0046] In one embodiment, the at least two receiving modes include a main receiver receiving mode and a low-power receiver receiving mode. The low-power receiver is also known as a low-power wake-up radio (LP-WUR) or an almost zero-power wake-up radio (AZP-WUR). It is understood that the main receiver and the low-power receiver have different receiving powers, which is beneficial for energy saving in the terminal.
[0047] In one embodiment, the at least two receiving modes correspond to receiving the control information using different numbers of receptions. For example, a high-performance receiver can complete the reception in one go, while a low-performance receiver can complete the reception in multiple sessions. Using a low-performance receiver is beneficial for energy saving in the terminal. For another example, a high-capacity (e.g., 4Rx) receiving capability can complete the reception in one go, while a low-capacity (e.g., 1Rx) receiving capability requires multiple receptions.
[0048] In one embodiment, the at least two receiving modes correspond to the use of different receiver types to receive the control information. Different receiver types may have different receiving power and receiving performance, thereby contributing to energy saving in the terminal.
[0049] In one embodiment, the terminal determines the target reception mode by: the terminal receiving first information sent by a network-side device, the first information indicating the target reception mode; and the terminal determining the target reception mode based on the first information.
[0050] In this embodiment, the network-side device can be a core network device. The core network device can indicate the target reception mode used by the terminal through first information (such as sending the first information via a NAS message). Typically, the core network device can know in advance at least two reception modes supported by the terminal, for example, through terminal reporting. In this embodiment, the network-side device can flexibly indicate the reception mode used by the terminal, which is beneficial to improving the spectrum efficiency and energy efficiency of the communication system.
[0051] In this embodiment, the network-side device can be an access network device (such as a base station). For example, when the core network device needs to page the terminal, the core network device sends at least two receiving modes supported by the terminal to the access network device (e.g., carried in the paging message between the core network and the access network). The access network device can determine which receiving mode the terminal should use. Once determined, the access network device can instruct the terminal to use which receiving mode (e.g., to receive paging) via broadcast, i.e., indicate the target receiving mode. Before the terminal receives the target receiving mode indicated by the network side via broadcast, both receiving modes of the terminal are enabled so that it can receive the first information sent by the network side. In this embodiment, the network-side device can flexibly instruct the terminal to use the receiving mode, which is beneficial for improving the spectrum efficiency and energy efficiency of the communication system.
[0052] In one embodiment, the first information is carried by at least one of a Non-Access Stratum (NAS) message, system information, a short message, or Downlink Control Information (DCI). This embodiment allows for flexible selection of the signaling format used to indicate the receiving mode employed by the terminal.
[0053] In one embodiment, before the terminal has received any first information, the terminal determines the target reception mode to be all supported reception modes.
[0054] In one embodiment, the terminal determining the target reception mode may further include: the terminal receiving second information sent by the access network device, the second information being used to instruct the terminal to switch reception modes; and the terminal determining the target reception mode based on the second information.
[0055] In this embodiment, the second information may simply instruct the terminal to switch receiving modes, and the terminal can automatically switch to another receiving mode; or, the second information may specifically instruct the terminal to switch to a particular receiving mode, and the terminal switches to the receiving mode indicated by the second information. By sending the second information through the access network device, the terminal can dynamically switch receiving modes based on the network's needs, improving the overall system's energy efficiency. For example, in time period 1, the network is in a non-energy-saving state and uses broadband to send paging messages. In time period 2, the network is in an energy-saving state and wants to use narrowband to send paging messages. Before using narrowband to send paging messages, the network can instruct the terminal via system information or SMS to switch to narrowband receiving mode to receive paging messages. Then, the terminal uses narrowband receiving mode to listen for paging messages. For the terminal, receiving the second information and using narrowband receiving mode to listen for paging messages saves terminal energy consumption.
[0056] In one embodiment, the second information is carried by at least one of system information, short message, or DCI. This embodiment allows for flexible selection of the signaling format used to indicate the receiving mode used by the terminal.
[0057] S204: When the terminal is in a Radio Resource Control (RRC) disconnected state, the terminal receives the control information according to the target reception mode.
[0058] The control information transmission method provided in this application embodiment allows the terminal to determine the receiving mode to be used and receive control information such as paging messages and / or low-power wake-up signals using the determined receiving mode. This enables flexible reception of control information and helps meet the needs of the terminal in different scenarios (such as coverage and power saving). At the same time, the network side can improve the energy efficiency of the communication system by utilizing the at least two receiving modes supported by the terminal.
[0059] In one embodiment, before the terminal determines the target reception mode, the method further includes: the terminal sending third information to a network-side device, the third information being used to report the reception mode that the terminal prefers to use.
[0060] In one embodiment, the terminal sending third information to the network-side device includes: when the terminal needs to change its receiving mode, the terminal sending the third information to the network-side device.
[0061] In one embodiment, the terminal sending third information to the network-side device includes: when the terminal is in RRC idle state, the terminal sends third information to the core network device through a registration process or a Tracking Area Update (TAU) process; or, when the terminal is in RRC inactive state, if the terminal needs to update the reception mode, the terminal sends third information to the access network device through a Radio Access Network Notification Area Update (RNAU) process.
[0062] This embodiment allows the terminal to autonomously determine the receiving mode to use, and helps to meet the needs of the terminal in different scenarios (such as coverage and power saving).
[0063] In one embodiment, before the terminal determines the target reception mode, the method further includes at least one of the following:
[0064] 1) The terminal sends fourth information to the network-side device, the fourth information being used to report the receiving mode requested by the terminal, and the terminal determining the target receiving mode includes: taking the receiving mode indicated by the fourth information as the target receiving mode.
[0065] In one embodiment, the terminal sending the fourth information to the network-side device includes: when the terminal needs to change its receiving mode, the terminal sending the fourth information to the network-side device.
[0066] In one embodiment, the terminal sending fourth information to the network-side device includes: when the terminal is in RRC idle state, the terminal sends fourth information to the core network device through a registration process or a TAU process; or, when the terminal is in RRC inactive state, if the terminal needs to update the receiving mode, the terminal sends fourth information to the access network device through an RNAU process.
[0067] This embodiment allows the terminal to autonomously determine the receiving mode to use, and helps to meet the needs of the terminal in different scenarios (such as coverage and power saving).
[0068] 2) The terminal receives confirmation information corresponding to the fourth information, the fourth information being used to report the receiving mode requested by the terminal, and the terminal determining the target receiving mode includes: taking the receiving mode indicated by the fourth information as the target receiving mode.
[0069] In this embodiment, the terminal can report the desired reception mode, and the network-side device can confirm the reception mode. This allows the terminal to autonomously determine the reception mode to use, which helps meet the terminal's needs in different scenarios (such as coverage and power saving).
[0070] In one embodiment, before the terminal determines the target reception mode, the method further includes: the terminal sending fifth information to a core network device or an access network device, the fifth information being used to report the at least two reception modes supported by the terminal.
[0071] The fifth piece of information can be carried by terminal capability information messages or NAS messages. For example, during registration, the UE sends the fifth piece of information to the base station. After receiving it, the base station can forward it to the core network, explicitly or implicitly indicating that the fifth piece of information is used for the terminal's RRC non-connected state. Subsequently, the core network sends the fifth piece of information to the terminal's current serving base station (the serving base station in the RRC connected state, or the anchor base station in the RRC INACTIVE state) for the anchor base station to use when the terminal is in the RRC INACTIVE state. When the terminal is in the RRC idle state, if the terminal needs to update the paging reception mode, the terminal sends the fifth piece of information through the TAU process or during registration. For another example, when the terminal is in the RRC inactive (INACTIVE) state, if the terminal needs to update the paging reception mode, the terminal sends the fifth piece of information through the RNAU process. The fifth piece of information can be carried through terminal capability information or other information, such as terminal auxiliary information (UAI).
[0072] In this embodiment, the terminal can report the supported receiving modes, which helps the network-side device identify that the terminal supports multiple receiving modes and determine the receiving mode used by the terminal according to the network-side requirements. This helps improve the performance of the communication system, such as improving the energy efficiency of the entire communication system.
[0073] To illustrate the control information transmission method provided in this application, a specific embodiment will be described below. This embodiment mainly describes the negotiation, configuration, and change process of the terminal's receiving mode.
[0074] The main idea of this embodiment is: for a terminal that supports two reception modes, how the network controls the reception mode used by the terminal; the terminal receives control information according to the reception mode configured by the network. The terminal can negotiate with the network in advance to use one of the reception modes, which can be done through the following steps.
[0075] Step 1: The terminal reports its capabilities to the network side, indicating the two reception modes it supports. The terminal can report its supported reception modes to the network side via fifth information, such as UE capability information (carried by a container, or explicitly indicating that the fifth information represents the terminal's RRC non-connected state capability). This fifth information can be reported to the base station, then forwarded by the base station to the core network, and stored in the core network for use by the core network when the terminal is in the RRC idle state. Subsequently, the core network sends this fifth information to the terminal's current serving base station (the serving base station in the RRC connected state, or the anchor base station in the RRC INACTIVE state), for use by the anchor base station when the terminal is in the RRC INACTIVE state. Optionally, the fifth information can be sent during the registration process or the TAU process.
[0076] Step 2: The terminal receives first information from the network side. This first information indicates which reception mode the terminal uses. For example, the terminal receives the first information from a NAS message sent by the core network device.
[0077] Optionally, before receiving the first information, the terminal reports its preferred / suggested reception mode to the network side, and the network side ultimately determines the reception mode used by the terminal. Alternatively, the terminal reports the reception mode it requests to use to the network side and receives confirmation information from the network side. In this way, the terminal and the network side reach a consensus on the reception mode used by the terminal in the RRC disconnected state.
[0078] Step 3: The terminal is in RRC disconnected state, and the terminal receives control information according to the receiving mode indicated in the first information.
[0079] Step 4: The terminal is in RRC disconnected state. The terminal receives the second information, which instructs the terminal to switch the receiving mode. Optionally, the network side can notify the terminal to switch the receiving mode through system information, short messages, or DCI.
[0080] Optionally, if the terminal needs to change the receiving mode, the terminal needs to notify the network side or negotiate with the network side again.
[0081] Regarding the interaction between the core network and the base station: the core network can inform the base station of the receiving mode currently used by the terminal, and the base station can then use this receiving mode to send control information to the terminal; alternatively, the core network can inform the base station of the receiving modes supported by the terminal and the receiving mode currently used by the terminal, allowing the base station to determine whether to adjust the terminal's receiving mode. When network-side requirements (such as energy-saving requirements) change, the network side can dynamically adjust the terminal's receiving mode.

[0083] Figure 3 This is a schematic diagram illustrating the implementation flow of a control information transmission method according to an embodiment of this application, which can be applied to core network devices. For example... Figure 3 As shown, the method 300 includes the following steps.
[0084] S302: The core network device sends first information to the terminal, the first information being used to indicate the target receiving mode used by the terminal; wherein, the terminal supports at least two receiving modes, the at least two receiving modes including the target receiving mode, the receiving mode being used to receive control information, the control information including paging messages and / or low-power wake-up signals.
[0085] In various embodiments of this application, the at least two receiving modes correspond to different communication bandwidths, or different receivers (e.g., power), or different number of receptions, or different types of low-power receivers are used.
[0086] In one embodiment, the at least two receiving modes correspond to receiving the control information using different communication bandwidths, such as using a broadband communication mode to receive the control information and using a narrowband communication mode to receive the control information, in order to improve the performance of the terminal and the network side.
[0087] In one embodiment, the at least two receiving modes include a main receiver receiving mode and a low-power receiver receiving mode. The low-power receiver is also known as a low-power wake-up radio (LP-WUR) or an almost zero-power wake-up radio (AZP-WUR). It is understood that the main receiver and the low-power receiver have different receiving powers, which is beneficial for energy saving in the terminal.
[0088] In one embodiment, the at least two receiving modes correspond to receiving the control information using different numbers of receptions. For example, a high-performance receiver can complete the reception in one go, while a low-performance receiver can complete the reception in multiple sessions. Using a low-performance receiver is beneficial for energy saving in the terminal. For another example, a high-capacity (e.g., 4Rx) receiving capability can complete the reception in one go, while a low-capacity (e.g., 1Rx) receiving capability requires multiple receptions.
[0089] In one embodiment, the at least two receiving modes correspond to the use of different receiver types to receive the control information. Different receiver types may have different receiving power and receiving performance, thereby contributing to energy saving in the terminal.
[0090] In this embodiment, since the terminal supports at least two receiving modes simultaneously, the core network device can instruct the terminal to use the receiving mode, so that the terminal can receive paging messages and / or low-power wake-up signals and other control information according to the receiving mode, thereby achieving flexible reception of control information and meeting the needs of the terminal in different scenarios (such as coverage and power saving); at the same time, the network side can improve the energy efficiency of the communication system by using the at least two receiving modes supported by the terminal.
[0091] In one embodiment, before the core network device sends the first information to the terminal, the method further includes at least one of the following:
[0092] 1) The core network device receives third information sent by the terminal, and the third information is used to report the receiving mode that the terminal prefers to use.
[0093] 2) The core network device receives the fourth information sent by the terminal, the fourth information being used to report the receiving mode requested by the terminal.
[0094] 3) The core network device sends confirmation information corresponding to the fourth information, which is used to report the receiving mode requested by the terminal.
[0095] In one embodiment, before the core network device sends the first information to the terminal, the method further includes: the core network device receiving the fifth information sent by the terminal, the fifth information being used to report the receiving modes supported by the terminal.
[0096] In one embodiment, the method further includes: the core network device sending sixth information to the access network device, the sixth information indicating at least one of the following: 1) the target reception mode used by the terminal; 2) the at least two reception modes supported by the terminal.
[0097] For example, the core network device may send the target reception mode used by the terminal and the terminal's identification information together in the interface paging message to the access network device. The access network device can then send control information, such as a paging message, based on the target reception mode used by the terminal. Alternatively, the core network device may send the two reception modes supported by the terminal and the terminal's identification information together in the interface paging message to the access network device. The access network device can then determine how to send the control information based on the reception modes currently enabled in the cell (e.g., the base station broadcasting instructions to use narrowband reception mode).

[0105] In one embodiment, the at least two receiving modes correspond to the use of different receiver types to receive the control information. Different receiver types may have different receiving power and receiving performance, thereby contributing to energy saving in the terminal.
[0106] In this embodiment, since the terminal supports at least two receiving modes simultaneously, the network-side device can instruct the terminal to use the receiving mode or instruct the terminal to switch receiving modes. The terminal can also report the preferred or recommended receiving modes, which is beneficial for the terminal to receive control information such as paging messages and / or low-power wake-up signals, enabling flexible reception of control information and meeting the terminal's needs in different scenarios (such as coverage and power saving). At the same time, the network side can improve the energy efficiency of the communication system by utilizing the at least two receiving modes supported by the terminal.
[0107] In one embodiment, receiving or sending the sixth information includes: 1) receiving the sixth information sent by a core network device or a second access network device, wherein the second access network device is the anchor access network device of the terminal; or 2) sending the sixth information to the second access network device, wherein the first access network device is the anchor access network device of the terminal.
