[0041] The control information transmission method provided by the embodiments of the present application will be described in detail below in combination with the accompanying drawings, some embodiments and application scenarios.

[0042] As shown in FIG. 2, the present application provides a control information transmission method 200, which can be executed by a terminal, in other words, the method can be executed by software or hardware installed in the terminal, and the method comprises the following steps.

[0043] S202: The terminal determines a target receiving mode; wherein the terminal supports at least two receiving modes, the at least two receiving modes include the target receiving mode, and the receiving mode is used to receive control information, and the control information includes a paging message and / or a low-power wake-up signal.

[0044] In this embodiment, the terminal can determine the receiving mode used from the at least two receiving modes supported by itself, i.e., the target receiving mode; and receive the control information according to the determined target receiving mode, for example, receive the paging message according to the target receiving mode, receive the low-power wake-up signal according to the target receiving mode, receive the paging message and the low-power wake-up signal according to the target receiving mode, etc.

[0045] In various embodiments of the present application, the at least two receiving modes correspond to different communication bandwidths respectively, or different receivers (such as power) respectively, or different receiving times respectively, or different types of low-power receivers used.

[0046] In one embodiment, the at least two receiving modes correspond to receiving the control information using different communication bandwidths respectively, for example, receiving the control information using a wideband communication mode, receiving the control information using a narrowband communication mode, etc., so as to improve the performance of the terminal and the network side.

[0047] For example, for a mobile phone, additional support of a narrowband communication mode on the basis of support of a wideband communication mode can not bring too much increase of cost and complexity, but can ensure basic communication according to additional coverage provided by a narrowband cell in some cases (such as in an area with poor wideband coverage). For another example, a wideband cell can enter a sleep mode according to dynamic changes of services, and the cell needs to be woken up before a terminal camps on the cell. If the terminal can camp on a narrowband cell at this time, the terminal does not need to frequently wake up the sleeping wideband cell due to mobility, thereby improving network and terminal energy efficiency, and when services of the terminal occur, the terminal accesses through the wideband cell.

[0048] In an embodiment, the at least two reception modes include a main receiver reception mode and a low-power receiver reception mode, i.e., a low-power wake-up receiver (LP-WUR) or an almost zero-power wake-up receiver (AZP-WUR). It can be understood that the main receiver and the low-power receiver have different reception powers, thereby facilitating energy saving of the terminal.

[0049] In an embodiment, the at least two reception modes correspond to reception of the control information using different numbers of receptions, for example, one reception using a high-performance receiver, and multiple receptions using a low-performance receiver, thereby facilitating energy saving of the terminal. For another example, one reception using a high-capability (such as 4Rx) reception capability, and multiple receptions using a low-capability (such as 1Rx) reception capability.

[0050] In an embodiment, the at least two reception modes correspond to reception of the control information using different types of receivers. The different types of receivers can have different reception powers and different reception performances, thereby facilitating energy saving of the terminal.

[0051] In an embodiment, the terminal determining the target reception mode includes: the terminal receiving first information sent by a network-side device, the first information being used to indicate the target reception mode; and the terminal determining the target reception mode based on the first information.

[0052] The network-side device in this embodiment can be a core network device, which can indicate the target reception mode used by the terminal through the first information (such as sending the first information through a NAS message). Generally, the core network device can know at least two reception modes supported by the terminal in advance, for example, through reporting by the terminal. In this embodiment, the network-side device can flexibly indicate the reception mode used by the terminal, thereby facilitating improvement of spectral efficiency and energy efficiency of the communication system.

[0053] The network-side device in this embodiment 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 (for example, carried in an interface paging message between the core network and the access network), and the access network device can determine which receiving mode the terminal uses. After the determination, the access network device can indicate the receiving mode used by the terminal to receive (such as receiving a page) through broadcasting, that is, indicate the target receiving mode. Before the terminal receives the target receiving mode indicated by the network side through broadcasting, the terminal starts both receiving modes, so that the first information sent by the network side can be received. In this embodiment, the network-side device can flexibly indicate the receiving mode used by the terminal, which is beneficial to improving the spectrum efficiency and energy efficiency of the communication system.

[0054] In one embodiment, the first information is carried in at least one of a non-access stratum (NAS) message, system information, a short message, or downlink control information (DCI). This embodiment can flexibly select a signaling format to indicate the receiving mode used by the terminal.

[0055] In one embodiment, before the terminal receives any first information, the terminal determines that the target receiving mode is all supported receiving modes.

[0056] In one embodiment, the terminal determining the target receiving mode can further include: receiving, by the terminal, second information sent by the access network device, the second information being used to indicate the terminal to switch the receiving mode; and determining, by the terminal, the target receiving mode based on the second information.

[0057] In this embodiment, the second information can only indicate the terminal to switch the receiving mode, and the terminal can automatically switch to another receiving mode; or the second information indicates the terminal to switch to a specific receiving mode, and the terminal switches to the receiving mode indicated by the second information. Through the second information sent by the access network device, the terminal can dynamically switch the receiving mode based on the demand of the network side, thereby improving the energy efficiency of the whole system. For example, in time period 1, the network side is in a non-energy-saving state, and the network side uses a wide band to send a paging message. In time period 2, the network side is in an energy-saving state, and the network side wants to use a narrow band to send a paging message. Before the network side uses the narrow band to send the paging message, the network side can indicate the terminal to switch to a narrow-band receiving mode to receive the paging message through system information or a short message, and then the terminal uses the narrow-band receiving mode to listen to the paging message. For the terminal, after receiving the second information, the terminal uses the narrow-band receiving mode to listen to the paging message, which can save the energy consumption of the terminal.

[0058] In one embodiment, the second information is carried by at least one of system information, a short message or DCI. This embodiment can flexibly select a signaling format to indicate the receiving mode used by the terminal.

[0059] S204: In a case where the terminal is in a radio resource control (RRC) non-connected state, the terminal receives the control information according to the target receiving mode.

[0060] The method for transmitting control information provided by the embodiments of the present application can determine the receiving mode used by the terminal, and receive the control information such as a paging message and / or a low-power wake-up signal using the determined receiving mode, so as to achieve flexible reception of control information and meet the needs of the terminal in different scenarios (such as coverage and power saving). Meanwhile, the network side can use the at least two receiving modes supported by the terminal to improve the energy efficiency of the communication system.

[0061] In one embodiment, before the terminal determines the target receiving mode, the method further includes: the terminal sending third information to the network side device, the third information being used to report the receiving mode preferred by the terminal.

[0062] In one embodiment, the terminal sending the third information to the network side device includes: in a case where the terminal has a demand for changing the receiving mode, the terminal sending the third information to the network side device.

[0063] In one embodiment, the terminal sending the third information to the network side device includes: in a case where the terminal is in an RRC idle state, the terminal sending the third information to the core network device through a registration process or a tracking area update (TAU) process; or in a case where the terminal is in an RRC inactive state, if the terminal wants to update the receiving mode, the terminal sends the third information to the access network device through a radio access network notification area update (RNAU) process.

[0064] This embodiment is beneficial to the terminal to autonomously determine the receiving mode used, and is beneficial to meeting the needs of the terminal in different scenarios (such as coverage and power saving).

[0065] In one embodiment, before the terminal determines the target receiving mode, the method further includes at least one of the following:

[0066] 1) the terminal sends fourth information to the network side device, the fourth information is used for reporting a receiving mode required by the terminal to use, and the terminal determines the target receiving mode by taking the receiving mode indicated by the fourth information as the target receiving mode.

[0067] In one embodiment, the terminal sending the fourth information to the network side device includes: in a case where the terminal has a demand for changing the receiving mode, the terminal sends the fourth information to the network side device.

[0068] In one embodiment, the terminal sending the fourth information to the network side device includes: in a case where the terminal is in an RRC idle state, the terminal sends the fourth information to a core network device through a registration process or a TAU process; or in a case where the terminal is in an RRC inactive state, if the terminal wants to update the receiving mode, the terminal sends the fourth information to an access network device through an RNAU process.

[0069] This embodiment is beneficial for the terminal to autonomously determine the receiving mode to use and is beneficial for meeting the demand of the terminal in different scenarios (such as coverage and power saving).

[0070] 2) the terminal receives confirmation information corresponding to the fourth information, the fourth information is used for reporting a receiving mode required by the terminal to use, and the terminal determines the target receiving mode by taking the receiving mode indicated by the fourth information as the target receiving mode.

[0071] In this embodiment, the terminal can report a required receiving mode, and the network side device can confirm the receiving mode, which is beneficial for the terminal to autonomously determine the receiving mode to use and is beneficial for meeting the demand of the terminal in different scenarios (such as coverage and power saving).

[0072] In one embodiment, before the terminal determines the target receiving mode, the method further includes: the terminal sends fifth information to a core network device or an access network device, the fifth information is used for reporting at least two receiving modes supported by the terminal.

[0073] The fifth information can be carried by a terminal capability information message or a NAS message. For example, in a registration process, the UE sends the fifth information to the base station, and the base station can forward the fifth information to the core network after receiving the fifth information, and explicitly or implicitly indicates that the fifth information is used for the RRC non-connected state of the terminal. The core network sends the fifth information to the current serving base station of the terminal (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. When the terminal is in the RRC idle state, if the terminal wants to update the paging reception mode, the terminal sends the fifth information in the TAU process or the registration process. For another example, when the terminal is in the RRC inactive (INACTIVE) state, if the terminal wants to update the paging reception mode, the terminal sends the fifth information in the RNAU process. The fifth information can be carried by terminal capability information or other information, such as terminal assistance information (UAI).

[0074] In this embodiment, the terminal can report the supported reception mode, which is beneficial for the network side device to identify that the terminal supports multiple reception modes, and to determine the reception mode used by the terminal according to the needs of the network side, and is beneficial for improving the performance of the communication system, for example, improving the energy efficiency of the entire communication system.

[0075] To describe the transmission method of control information provided by the embodiments of the present application in detail, a specific embodiment will be described below. This embodiment mainly introduces the negotiation, configuration, and change process of the reception mode of the terminal.

[0076] The main idea of this embodiment is: for a terminal supporting two reception modes, how does the network control the reception mode used by the terminal; and the terminal receives control information according to the reception mode configured by the network. The terminal can negotiate with the network side in advance to use one of the reception modes, which can be achieved through the following steps.

[0077] Step 1: The terminal reports the terminal capability to the network side, indicating the two supported reception modes. The terminal can report the supported reception mode to the network side through the fifth information, such as the terminal capability information (UE capability information) message (carried by a container or explicitly supporting the fifth information as the RRC non-connected state capability of the terminal). The fifth information can be reported to the base station, and then forwarded to the core network by the base station, and stored in the core network for use when the terminal is in the RRC idle state. The core network sends the fifth information to the current serving base station of the terminal (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 in the registration process or the TAU process.

[0078] Step 2: The terminal receives the first information from the network side, and the first information is used to indicate which receiving mode the terminal uses. For example, the terminal receives the first information from the NAS message sent by the core network device.

[0079] Optionally, before receiving the first information, the terminal reports its preferred / suggested receiving mode to the network side, and finally the receiving mode used by the terminal is determined by the network side. Alternatively, the terminal reports the receiving mode it requires to use to the network side, and receives the confirmation information from the network side. In this way, the terminal and the network side reach a consistent understanding of the receiving mode used by the terminal in the RRC non-connected state.

[0080] Step 3: The terminal is in the RRC non-connected state, and the terminal receives the control information according to the receiving mode indicated in the first information.

[0081] Step 4: The terminal is in the RRC non-connected state, and the terminal receives the second information, which is used to indicate the terminal to switch the receiving mode.
