Description

Technical Field

[0001] The present application relates to the field of wireless communications, and in particular to a paging method and apparatus. Background Art

[0002] In a communication system, a terminal is usually in a standby state. When the terminal is in the standby state, it will periodically detect paging messages and use the paging messages to determine whether it needs to establish a connection with the network device. For example, when the terminal is in the standby state, it will detect the physical downlink control channel (PDCCH) used to carry the paging message, and receive the physical downlink shared channel (PDSCH) carrying the terminal identifier based on the PDCCH. If the terminal identifier carried in the PDSCH includes the identifier of the terminal, it is determined that the terminal is paged. Subsequently, the terminal will establish a connection with the network device. In the above process, after the terminal detects the PDCCH, it also needs to detect the PDSCH to determine whether it is paged. Therefore, the power consumption of the terminal receiving the paging message is relatively high.

[0003] To reduce the power consumption of terminals receiving paging messages, the terminal identifier can be carried in the PDCCH. In this way, the terminal can determine whether it has been paged after detecting the PDCCH. However, how to make the terminal compatible with the above two paging methods is an urgent problem that needs to be solved. Summary of the Invention

[0004] The present application provides a paging method and apparatus, and the terminal is compatible with two paging modes.

[0005] To achieve the above objectives, the embodiments of the present application adopt the following technical solutions:

[0006] In a first aspect, an embodiment of the present application provides a paging method, the method comprising: receiving a paging PDCCH from a network device; when the paging PDCCH is a first type of paging PDCCH, determining whether to be paged based on the first type of paging PDCCH; when the paging PDCCH is a second type of paging PDCCH, receiving a paging PDSCH, and determining whether to be paged based on the paging PDSCH.

[0007] In the method provided in the first aspect above, the terminal can receive a paging PDCCH from the network device and, when the paging PDCCH is a first type of paging PDCCH, determine whether to be paged based on the first type of paging PDCCH; when the paging PDCCH is a second type of paging PDCCH, receive a paging PDSCH based on the second paging PDCCH and determine whether to be paged based on the paging PDSCH. In this way, the terminal can be compatible with both the first type of paging PDCCH and the second type of paging PDCCH. The network device can also determine the method for paging the terminal as needed, rather than using only a single method to page the terminal.

[0008] In a possible implementation, the first type of paging PDCCH and the second type of paging PDCCH have the same size. Based on the above method, the complexity of blind detection of the paging PDCCH by the terminal can be reduced.

[0009] In one possible implementation, the first type of paging PDCCH and the second type of paging PDCCH use different scrambling methods. Based on the above method, the first type of paging PDCCH and the second type of paging PDCCH use different scrambling methods. Therefore, the terminal can determine the type of paging PDCCH based on the scrambling method, thereby correctly parsing the paging PDCCH.

[0010] In a possible implementation, the paging PDCCH includes paging type indication information, and the paging type indication information is used to indicate the type of the paging PDCCH. Based on the above method, the terminal can determine the type of the paging PDCCH according to the paging type indication information, so as to correctly parse the paging PDCCH.

[0011] In one possible implementation, the paging type indication information occupies the lowest N bits of the paging PDCCH, where N is a positive number. Based on the above method, for terminals supporting the second type of paging PDCCH, the lower bits of the second type of paging PDCCH are reserved and the terminals do not need to identify them. For terminals supporting the first type of paging PDCCH, the type of paging PDCCH can be determined based on the paging type indication information, thereby achieving better compatibility.

[0012] In one possible implementation, the method further includes: receiving a notification message from the network device, the notification message being used to indicate the type of the paging PDCCH. Based on the above method, the terminal can receive a notification message from the network device indicating the type of the paging PDCCH, thereby being able to determine the type of the paging PDCCH based on the notification message.

[0013] In one possible implementation, the notification message also indicates the number of paging PDCCHs that can be detected within a paging opportunity. Based on the above method, the terminal can determine the number of paging PDCCHs that can be detected within a paging opportunity through the notification message. In this way, within a paging opportunity, after receiving the number of paging PDCCHs indicated in the notification message, the terminal can stop receiving paging PDCCHs, thereby reducing terminal power consumption.

[0014] In a possible implementation, the notification message is a high-layer signaling. Based on the above method, the terminal can receive the notification message via the high-layer signaling, so that the terminal can determine the type of the paging PDCCH.

[0015] In one possible implementation, the first type of paging PDCCH includes a terminal identifier, and the paging PDSCH includes at least one terminal identifier. Based on the above method, the first type of paging PDCCH includes a terminal identifier, so the first type of paging PDCCH and the second type of paging PDCCH can be the same size, thereby reducing the complexity of the terminal's blind detection of the paging PDCCH. In addition, the terminal can also use the same scrambling method as the second type of paging PDCCH to further reduce the complexity of the terminal's blind detection of the paging PDCCH.

[0016] In a possible implementation, the second type of paging PDCCH does not include the terminal's identity. Based on the above method, the second type of paging PDCCH does not include the terminal's identity, so the terminal needs to receive the paging PDSCH including the terminal's identity according to the second type of paging PDCCH.

[0017] A possible implementation method is to determine whether a terminal is paged based on the first type of paging PDCCH, including: if the first type of paging PDCCH includes the identifier of the first terminal, determining that the first terminal is paged; if none of the paging PDCCHs within the paging opportunity where the paging PDCCH is located includes the identifier of the first terminal, determining that the first terminal is not paged; determining whether a terminal is paged based on the paging PDSCH, including: if the paging PDSCH includes the identifier of the first terminal device, determining that the first terminal device is paged; if the paging PDSCH does not include the identifier of the first terminal device, determining that the first terminal device is not paged. Based on the above method, if the paging PDCCH is the first type of paging PDCCH, the terminal can determine whether it is paged based on the identifier of the terminal in the first type of paging PDCCH. If the paging PDCCH is the second type of paging PDCCH, the terminal can determine whether it is paged based on the identifier of the terminal in the paging PDSCH.

[0018] In one possible implementation, the terminal identifier included in the paging PDCCH is a first type identifier or a second type identifier, the terminal identifier included in the paging PDSCH is a second type identifier, and the first type identifier is a part of the second type identifier. Based on the above method, the terminal identifier included in the paging PDCCH can be multiple types of identifiers.

[0019] In one possible implementation, the second type of identifier is a 5G service temporary mobile subscriber identity (5G S-temporary mobile subscriber identity, 5G-S-TMSI) or an inactive radio network temporary identifier (I-RNTI). Based on the above method, the paging PDCCH may include 5G-S-TMSI, I-RNTI, part of the 5G-S-TMSI, or part of the I-RNTI, so that the terminal can determine whether it is being paged.

[0020] A possible implementation method is that when the paging PDCCH is a first type of paging PDCCH, within the paging opportunity where the paging PDCCH is located, the number of terminals to be paged is less than or equal to a first threshold; or, the service coverage of the network device is less than or equal to a second threshold; or, the traffic volume of the network device is less than or equal to a third threshold; the distance between the location of the network device and the location of the city center is greater than or equal to a fourth threshold; or, the terminal to be paged is in an inactive state; or, the paging identifier of the terminal to be paged is I-RNTI. Based on the above method, when the number of terminals to be paged within the paging opportunity where the paging PDCCH is located is less than or equal to the first threshold; or, the service coverage of the network device is less than or equal to the second threshold; or, the business volume of the network device is less than or equal to the third threshold; when the distance between the location of the network device and the location of the city center is greater than or equal to the fourth threshold, the network device pages the terminal through the first type of paging PDCCH; or, when the terminal to be paged is in an inactive state, the network device pages the terminal through the first type of paging PDCCH; or, when the paging identifier of the terminal to be paged is I-RNTI, the network device pages the terminal through the first type of paging PDCCH.

[0021] In a second aspect, an embodiment of the present application provides a paging method, which includes: determining a paging PDCCH; when the paging PDCCH is a first type of paging PDCCH, sending the paging PDCCH to a terminal; when the paging PDCCH is a second type of paging PDCCH, sending the paging PDCCH to the terminal and sending a paging PDSCH to the terminal.

[0022] The method provided by the above-mentioned second aspect is that when the paging PDCCH is a first type of paging PDCCH, the network device sends the paging PDCCH to the terminal so that the terminal determines whether to be paged based on the first type of paging PDCCH; when the paging PDCCH is a second type of paging PDCCH, the network device sends the paging PDCCH to the terminal and sends the paging PDSCH to the terminal so that the terminal determines whether to be paged based on the paging PDSCH.

[0023] In a possible implementation, the first type of paging PDCCH and the second type of paging PDCCH have the same size. Based on the above method, the complexity of blind detection of the paging PDCCH by the terminal can be reduced.

[0024] In one possible implementation, the first type of paging PDCCH and the second type of paging PDCCH use different scrambling schemes. Based on the above method, the first type of paging PDCCH and the second type of paging PDCCH use different scrambling schemes. In this way, the terminal can determine the type of paging PDCCH based on the scrambling scheme, thereby correctly parsing the paging PDCCH.

[0025] In a possible implementation, the paging PDCCH includes paging type indication information, and the paging type indication information is used to indicate the type of the paging PDCCH. Based on the above method, the terminal can determine the type of the paging PDCCH according to the paging type indication information, so as to correctly parse the paging PDCCH.

[0026] In one possible implementation, the paging type indication information occupies the lowest N bits of the paging PDCCH, where N is a positive number. Based on the above method, for terminals supporting the second type of paging PDCCH, the lower bits of the second type of paging PDCCH are reserved and the terminals do not need to identify them. For terminals supporting the first type of paging PDCCH, the type of paging PDCCH can be determined based on the paging type indication information, thereby achieving better compatibility.

[0027] In a possible implementation, the method further includes: sending a notification message to the terminal, the notification message being used to indicate the type of the paging PDCCH. Based on the above method, the network device can send a notification message to the terminal indicating the type of the paging PDCCH, so that the terminal determines the type of the paging PDCCH according to the notification message.

[0028] In one possible implementation, the notification message also indicates the number of paging PDCCHs that can be detected within a paging opportunity. Based on the above method, the terminal can determine the number of paging PDCCHs that can be detected within a paging opportunity through the notification message. In this way, within a paging opportunity, after receiving the number of paging PDCCHs indicated in the notification message, the terminal can stop receiving paging PDCCHs, thereby reducing terminal power consumption.

[0029] In a possible implementation, the first message is a high-layer signaling. Based on the above method, the network device may send the notification message to the terminal via high-layer signaling, so that the terminal can determine the type of the paging PDCCH.

[0030] In one possible implementation, the first type of paging PDCCH includes a terminal identifier, and the paging PDSCH includes at least one terminal identifier. Based on the above method, the first type of paging PDCCH includes a terminal identifier, so the first type of paging PDCCH and the second type of paging PDCCH can be the same size, thereby reducing the complexity of the terminal's blind detection of the paging PDCCH. In addition, the terminal can also use the same scrambling method as the second type of paging PDCCH to further reduce the complexity of the terminal's blind detection of the paging PDCCH.

[0031] In a possible implementation, the second type of paging PDCCH does not include the terminal's identity. Based on the above method, the second type of paging PDCCH does not include the terminal's identity, so the terminal needs to receive the paging PDSCH including the terminal's identity according to the second type of paging PDCCH.

[0032] In one possible implementation, the terminal identifier included in the paging PDCCH is a first type identifier or a second type identifier, the terminal identifier included in the paging PDSCH is a second type identifier, and the first type identifier is a part of the second type identifier. Based on the above method, the terminal identifier included in the paging PDCCH can be multiple types of identifiers.

[0033] In one possible implementation, the second type of identifier is a 5G-S-TMSI or an I-RNTI. Based on the above method, the paging PDCCH may include a 5G-S-TMSI, an I-RNTI, a portion of a 5G-S-TMSI, or a portion of an I-RNTI, so that the terminal can determine whether it is being paged.

[0034] A possible implementation method is applied to a network device. When the paging PDCCH is a first type of paging PDCCH, the number of terminals to be paged within the paging opportunity where the paging PDCCH is located is less than or equal to a first threshold; or, the service coverage of the network device is less than or equal to a second threshold; or, the traffic volume of the network device is less than or equal to a third threshold; the distance between the location of the network device and the location of the city center is greater than or equal to a fourth threshold; or, the terminal to be paged is in an inactive state; or, the paging identifier of the terminal to be paged is I-RNTI. Based on the above method, when the number of terminals to be paged within the paging opportunity where the paging PDCCH is located is less than or equal to the first threshold; or, the service coverage of the network device is less than or equal to the second threshold; or, the business volume of the network device is less than or equal to the third threshold; when the distance between the location of the network device and the location of the city center is greater than or equal to the fourth threshold, the network device pages the terminal through the first type of paging PDCCH; or, when the terminal to be paged is in an inactive state, the network device pages the terminal through the first type of paging PDCCH; or, when the paging identifier of the terminal to be paged is I-RNTI, the network device pages the terminal through the first type of paging PDCCH.

[0059] The implementation of the embodiments of the present application will be described in detail below with reference to the accompanying drawings.

[0060] The method provided in the embodiment of the present application can be used in various communication systems. For example, the communication system can be a long term evolution (LTE) system, a fifth generation (5G) communication system, a new radio (NR) system, a wireless fidelity (WiFi) system, a communication system related to the third generation partnership project (3GPP), and a communication system evolved in the future, etc., without limitation. Figure 1 Taking the communication system 10 shown as an example, the method provided in the embodiment of the present application is described.

[0061] like Figure 1 , which is a schematic diagram of the architecture of the communication system 10 provided in an embodiment of the present application. Figure 1 In the figure, the communication system 10 may include one or more network devices 101 (only one is shown) and terminals 102 to 104 that can communicate with the network device 101. Figure 1 It is only a schematic diagram and does not constitute a limitation on the applicable scenarios of the technical solution provided in this application.

[0062] exist Figure 1 In the wireless communication network, network devices can provide wireless access services for terminals. Specifically, each network device corresponds to a service coverage area. Terminals entering the area can communicate with the network device through the Uu port to receive the wireless access services provided by the network device. The terminal and the network device can communicate through the Uu port link. Among them, the Uu port link can be divided into uplink (UL) and downlink (DL) according to the direction of the data transmitted thereon. The UL can transmit uplink data sent from the terminal to the network device, and the DL can transmit downlink data transmitted from the network device to the terminal. For example: Figure 1 In the example, terminal 103 is located in the coverage area of ​​network device 101. Network device 101 can send downlink data to terminal 103 via DL, and terminal 103 can send uplink data to network device 101 via UL.

[0063] A terminal can communicate with other terminals via a direct communication link. The direct communication link between a terminal and other terminals can be called a side link, a side link (SL), or a device-to-device link (D2D link). For example, taking the direct communication link between a terminal and other terminals as a side link, Figure 1 Terminal 102 and terminal 103 may communicate via a side link, and terminal 104 and terminal 103 may communicate via a side link.

[0064] Figure 1 The network device in, for example: network device 101 can be any device with wireless transceiver function. Including but not limited to: evolved base station (NodeB or eNB or e-NodeB, evolutionary Node B) in LTE, base station (gNodeB or gNB) or transmission receiving point (transmission reception point / transmission reception point, TRP) in NR, base station of subsequent evolution of 3GPP, access node in WiFi system, wireless relay node, wireless backhaul node, etc. The base station can be: macro base station, micro base station, pico base station, small station, relay station, or balloon station, etc. Multiple base stations can support the network of the same technology mentioned above, or support the network of different technologies mentioned above. The base station can include one or more co-site or non-co-site TRPs. The network device can also be a wireless controller, a centralized unit (CU), and / or a distributed unit (DU) in a cloud radio access network (CRAN) scenario. The network device can also be a server, a wearable device, a machine communication device, or an in-vehicle device, etc. The following description uses a base station as an example of a network device. The multiple network devices may be base stations of the same type or different types. A base station may communicate with a terminal or communicate with the terminal through a relay station. A terminal may communicate with multiple base stations of different technologies. For example, a terminal may communicate with a base station supporting an LTE network or a base station supporting a 5G network, and may also support dual connectivity with a base station of an LTE network and a base station of a 5G network.

Wearable devices may also be referred to as wearable smart devices, which are a general term for wearable devices that are intelligently designed and developed using wearable technology for daily wear, such as glasses, gloves, watches, clothing, and shoes. A wearable device is a portable device that is worn directly on the body or integrated into the user's clothes or accessories. Wearable devices are not just hardware devices, but also achieve powerful functions through software support, data interaction, and cloud interaction. In a broad sense, wearable smart devices include those that are fully functional, large in size, and can achieve complete or partial functions without relying on smartphones, such as smart watches or smart glasses, as well as those that only focus on a certain type of application function and need to be used in conjunction with other devices such as smartphones, such as various smart bracelets and smart jewelry for vital sign monitoring.

[0081] The following combination Figure 1 and Figure 2 The paging method provided in the embodiment of the present application is described in detail.

[0082] It should be noted that the paging method provided in the embodiment of the present application can be applied between a network device and a terminal, and can also be applied between terminals. The embodiment of the present application is introduced by taking the application of the paging method between a network device and a terminal as an example. When the paging method is applied between terminals, you can refer to the following description of the application of the paging method between a network device and a terminal. The difference is that when the paging method is applied between a network device and a terminal, the network device and the terminal communicate through PDCCH or PDSCH. When the paging method is applied between terminals, the terminals communicate through the physical sidelink control channel (PSSCH) or the physical sidelink shared channel (PSSCH).

[0083] It should be noted that the message names between network elements or the names of parameters in the messages in the following embodiments of the present application are only examples, and other names may be used in specific implementations. The embodiments of the present application do not specifically limit this.

[0084] It should be noted that in the following embodiments of this application, words such as "exemplary" or "for example" are used to indicate examples, illustrations, or descriptions. Any embodiment or design described as "exemplary" or "for example" in the following embodiments of this application should not be construed as being preferred or advantageous over other embodiments or designs. Rather, the use of words such as "exemplary" or "for example" is intended to present the relevant concepts in a concrete manner.

[0085] It can be understood that the same step or steps or messages with the same function in the embodiments of the present application can be referenced by each other in different embodiments.

[0086] It is understood that in the embodiments of the present application, the network device and / or terminal may perform some or all of the steps in the embodiments of the present application. These steps are merely examples, and the embodiments of the present application may also perform other steps or variations of various steps. In addition, the various steps may be performed in a different order than those presented in the embodiments of the present application, and it is possible that not all of the steps in the embodiments of the present application need to be performed.

[0087] In the embodiments of the present application, the specific structure of the execution subject of the paging method is not particularly limited in the embodiments of the present application. As long as the program that records the code of the paging method of the embodiments of the present application can be run to communicate according to the paging method of the embodiments of the present application, for example, the execution subject of the paging method provided in the embodiments of the present application can be a network device, or a component applied to a network device, such as a chip, and this application does not limit this. Alternatively, the execution subject of the paging method provided in the embodiments of the present application can be a terminal, or a component applied to a terminal, such as a chip, and this application does not limit this. The following embodiments are described by taking the execution subjects of the paging method as network devices and terminals as examples.

[0088] like Figure 3 As shown, a paging method provided in an embodiment of the present application includes steps 301 to 303.

[0089] Step 301: The network device determines a paging PDCCH.

[0090] Among them, the network device can be Figure 1 The network device 101 in FIG.

[0091] The paging PDCCH may be a first type paging PDCCH or a second type paging PDCCH. The first type paging PDCCH may include a terminal identifier. If multiple terminals are paged, the network device needs to determine multiple paging PDCCHs, each including a terminal identifier. The second type paging PDCCH does not include a terminal identifier.

[0092] In one possible implementation, the identifier of the terminal included in the first type of paging PDCCH is a first type of identifier or a second type of identifier. The first type of identifier is a part of the second type of identifier. It can be understood that a part of the second type of identifier is intercepted as the first type of identifier. For example, the first type of identifier is the high M bits of the second type of identifier. M is a positive integer. The second type of identifier can be a 5G service temporary mobile user identity (5G S-temporary mobile subscriber identity, 5G-S-TMSI) or an inactive radio network temporary identifier (inactive radio network temporary identifier, I-RNTI), etc.

[0093] Exemplarily, taking the case where the terminal identifier bit is R bits and the payload size of the first type of paging PDCCH is K bits, if R is greater than or equal to K, then M=K. In this case, the first type of paging PDCCH includes the first type of identifier. If R is less than K, then M=R. In this case, the first type of paging PDCCH includes the second type of identifier. At this time, in addition to the second type of identifier, the first type of paging PDCCH also includes a reserved bit of (KR) bits, and the reserved bit is located in the low bit of the first type of paging PDCCH.

[0094] Please refer to Table 1, which provides several examples of the first-type paging PDCCH payload size, the number of bits of the terminal identifier, the value of M, and the reserved bits in the first-type paging PDCCH. In Table 1, the unit of each number is bit. In Table 1, when the first-type paging PDCCH payload size is 39 bits and the number of bits of the terminal identifier is 48 bits, the first-type paging PDCCH includes the first-type identifier, M is 39 bits, and the reserved bits in the first-type paging PDCCH are 0 bits, that is, the first-type paging PDCCH does not include reserved bits. When the first-type paging PDCCH payload size is 39 bits and the number of bits of the terminal identifier is 41 bits, the first-type paging PDCCH includes the first-type identifier, M is 39 bits, and the reserved bits in the first-type paging PDCCH are 0 bits. When the first-type paging PDCCH payload size is 42 bits and the terminal identifier bit position is 41 bits, the first-type paging PDCCH includes the second-type identifier, M is 41 bits, and the reserved bit in the first-type paging PDCCH is 1 bit. When the first-type paging PDCCH payload size is 44 bits and the terminal identifier bit position is 41 bits, the first-type paging PDCCH includes the second-type identifier, M is 41 bits, and the reserved bit in the first-type paging PDCCH is 3 bits.

[0095] Table 1

[0096]

[0097] It should be noted that when a terminal detects a paging message in a specific paging opportunity, the paging opportunity is determined by the lower L bits of the terminal's identifier, where L is a positive integer. Therefore, if the first type of paging PDCCH includes the first type of identifier, as long as (L + M) is greater than or equal to the number of bits of the second type of identifier, no false or erroneous paging will occur. For example, if the terminal's identifier is 41 bits, the terminal's paging opportunity is determined by the lower 10 bits of the terminal's identifier. If the network device determines to page the terminal, the first type of paging PDCCH only needs to include the upper 41-10 = 31 bits of the terminal's identifier.

[0098] In a possible implementation, the second type of paging PDCCH includes physical layer signaling for receiving a paging PDSCH, for example, information such as time-frequency resources of the paging PDSCH.

[0099] Exemplarily, the second type of paging PDCCH includes one or more of the following information: a short message indicator, a short message, a frequency domain resource indicator, a time domain resource indicator, a virtual resource block (VRB) to physical resource block (PRB) mapping (VRB-to-PRB mapping) method indication, a modulation and coding method, a transport block scaling value, and reserved bits, etc. Among them, the introduction of the short message indicator, the short message, the frequency domain resource indicator, the time domain resource indicator, the VRB-to-PRB mapping method indication, the modulation and coding method, the transport block scaling value, and the reserved bits can be referred to the explanation in the conventional technology and will not be repeated here.

[0100] In one possible implementation, the first type of paging PDCCH and the second type of paging PDCCH have the same size. For example, the first type of paging PDCCH and the second type of paging PDCCH have the same payload size, thereby reducing the complexity of the terminal's blind detection of the paging PDCCH.

[0101] For example, the formats of the first type paging PDCCH and the second type paging PDCCH may be as follows: Figure 4 shown. Figure 4 In the present invention, the first type of paging PDCCH includes a first type of identifier or a second type of identifier, and the second type of paging PDCCH includes a short message indication, a short message, a frequency domain resource indication, a time domain resource indication, a VRB-to-PRB mapping method indication, a modulation and coding method, a transport block scaling value, and a reserved bit.

[0102] Furthermore, for the same DL bandwidth part (BWP), the first type paging PDCCH and the second type paging PDCCH have the same size.

[0103] Exemplarily, the sizes of the first type of paging PDCCH and the second type of paging PDCCH corresponding to different DL BWPs can be as shown in Table 2. In Table 2, when the DL BWP is 12 RBs and the frequency domain resource indication bit width is 7 bits, the sizes of the first type of paging PDCCH and the second type of paging PDCCH are both 35 bits. When the DL BWP is 24 RBs and the frequency domain resource indication bit width is 9 bits, the sizes of the first type of paging PDCCH and the second type of paging PDCCH are both 37 bits. When the DL BWP is 48 RBs and the frequency domain resource indication bit width is 11 bits, the sizes of the first type of paging PDCCH and the second type of paging PDCCH are both 39 bits. When the DL BWP is 96 RBs and the frequency domain resource indication bit width is 13 bits, the sizes of the first type of paging PDCCH and the second type of paging PDCCH are both 41 bits.

[0104] Table 2

[0105]

[0106] It should be noted that Table 2 is only an example of the sizes of the first type paging PDCCH and the second type paging PDCCH. In actual applications, the sizes of the first type paging PDCCH and the second type paging PDCCH may also be other values ​​without limitation.

[0107] It should be noted that the scrambling methods of the first type of paging PDCCH and the second type of paging PDCCH can be the same or different. For example, the second type of paging PDCCH can be scrambled using a paging radio network temporary identifier (P-RNTI), and the first type of paging PDCCH can be scrambled using an RNTI different from the P-RNTI. If the scrambling methods of the first type of paging PDCCH and the second type of paging PDCCH are the same, the complexity of the terminal's blind detection of the paging PDCCH can be further reduced.

[0108] In a possible implementation, the paging PDCCH includes paging type indication information, where the paging type indication information is used to indicate the type of the paging PDCCH.

[0109] It can be understood that the paging type indication information may be included in the first type of paging PDCCH but not included in the second type of paging PDCCH; or, the paging type indication information may be included in the second type of paging PDCCH but not included in the first type of paging PDCCH; or, the indication information may be included in both the first type of paging PDCCH and the second type of paging PDCCH.

[0110] Exemplarily, the paging type indication information is 1-bit indication information. For example, when the paging type indication information is 1, it indicates that the paging PDCCH is the first type of paging PDCCH, and when the paging type indication information is 0, it indicates that the paging PDCCH is the second type of paging PDCCH, and vice versa.

[0111] Furthermore, the paging type indication information occupies the lowest N bits of the paging PDCCH, where N is a positive number.

[0112] For example, Figure 5 As shown, for the first type of paging PDCCH, the paging type indication information occupies the lowest N bits of the paging PDCCH. For the second type of paging PDCCH, the paging type indication information occupies the bits in the reserved bits of the paging PDCCH. For terminals that support the second type of paging PDCCH, the lower bits of the second type of paging PDCCH are reserved bits and the terminals do not need to identify them. For terminals that support the first type of paging PDCCH, the type of paging PDCCH can be determined based on the paging type indication information. Therefore, compatibility is better.

[0113] Exemplarily, taking the terminal's identifier as R bits and the first type of paging PDCCH's payload size as K bits as an example, if R is greater than or equal to K, then M = (KN). In this case, the first type of paging PDCCH includes the first type of identifier. If R is less than K, then M = R. In this case, the first type of paging PDCCH includes the second type of identifier. At this time, in addition to the second type of identifier, the first type of paging PDCCH also includes a reserved bit of (KRN) bits, and the reserved bit is located in the low bit of the first type of paging PDCCH.

[0114] Please refer to Table 3, which provides several exemplary descriptions of the first-type paging PDCCH payload size, the number of terminal identifier bits, the value of M, and the reserved bits in the first-type paging PDCCH when N=1. In Table 3, the unit of each number is bit. In Table 3, when the first-type paging PDCCH payload size is 39 bits and the number of terminal identifier bits is 48 bits, the first-type paging PDCCH includes the first-type identifier, M is 38 bits, and the reserved bits in the first-type paging PDCCH are 0 bits, that is, the first-type paging PDCCH does not include reserved bits. When the first-type paging PDCCH payload size is 39 bits and the number of terminal identifier bits is 41 bits, the first-type paging PDCCH includes the first-type identifier, M is 38 bits, and the reserved bits in the first-type paging PDCCH are 0 bits. When the first-type paging PDCCH payload size is 42 bits and the terminal identifier bit position is 41 bits, the first-type paging PDCCH includes the second-type identifier, M is 41 bits, and the reserved bits in the first-type paging PDCCH are 0 bits. When the first-type paging PDCCH payload size is 44 bits and the terminal identifier bit position is 41 bits, the first-type paging PDCCH includes the second-type identifier, M is 41 bits, and the reserved bits in the first-type paging PDCCH are 2 bits.

[0115] Table 3

[0116]

[0117] In one possible implementation, the network device determines the paging PDCCH in the following exemplary manner:

[0118] Method 1: The network device determines the paging PDCCH based on the number of terminals to be paged. Generally speaking, when the number of terminals to be paged is small, the paging PDCCH determined by the network device is the first type of paging PDCCH; when the number of terminals to be paged is large, the paging PDCCH determined by the network device is the second type of paging PDCCH.

[0119] Exemplarily, within the paging opportunity where the paging PDCCH is located, the number of terminals to be paged is less than or equal to the first threshold, and the paging PDCCH determined by the network device is the first type of paging PDCCH; if the number of terminals to be paged is greater than the first threshold, the paging PDCCH determined by the network device is the second type of paging PDCCH. For the introduction of paging opportunities, reference can be made to the explanations in conventional technology. Taking the first threshold of 4 as an example, within the paging opportunity where the paging PDCCH is located, if the number of terminals to be paged is 3, the paging PDCCH determined by the network device is the first type of paging PDCCH; if the number of terminals to be paged is 5, the paging PDCCH determined by the network device is the second type of paging PDCCH.

[0120] Method 2: The network device determines the paging PDCCH based on the service coverage of the network device. Generally speaking, when the service coverage of the network device is small, the paging PDCCH determined by the network device is the first type of paging PDCCH; when the service coverage of the network device is large, the paging PDCCH determined by the network device is the second type of paging PDCCH.

[0121] Exemplarily, if the service coverage of the network device is less than or equal to the second threshold, the paging PDCCH determined by the network device is a first type of paging PDCCH; if the service coverage of the network device is greater than the second threshold, the paging PDCCH determined by the network device is a second type of paging PDCCH. For example, if the network device is a micro base station with a service coverage less than the second threshold, the paging PDCCH determined by the network device is a first type of paging PDCCH; if the network device is a macro base station with a service coverage greater than the second threshold, the paging PDCCH determined by the network device is a second type of paging PDCCH.

[0122] Mode 3: The network device determines the paging PDCCH based on the traffic volume. Generally speaking, when the traffic volume of the network device is small, the paging PDCCH determined by the network device is the first type of paging PDCCH; when the traffic volume of the network device is large, the paging PDCCH determined by the network device is the second type of paging PDCCH.

[0123] Exemplarily, if the traffic volume of the network device is less than or equal to a third threshold, the paging PDCCH determined by the network device is a first type of paging PDCCH; if the traffic volume of the network device is greater than the third threshold, the paging PDCCH determined by the network device is a second type of paging PDCCH. For example, if the traffic volume during the day is greater than the third threshold, the paging PDCCH determined by the network device is a second type of paging PDCCH; if the traffic volume at night is less than the third threshold, the paging PDCCH determined by the network device is a first type of paging PDCCH.

[0124] Method 4: The network device determines a paging PDCCH based on the network device's location. Generally speaking, when the network device is located in a low-density area (e.g., a suburban area), the paging PDCCH determined by the network device is a first-type paging PDCCH; when the network device is located in a high-density area (e.g., an urban area), the paging PDCCH determined by the network device is a second-type paging PDCCH.

[0125] Exemplarily, if the distance between the location of the network device and the location of the city center is greater than or equal to the fourth threshold, the paging PDCCH determined by the network device is the first type of paging PDCCH; if the distance between the location of the network device and the location of the city center is less than the fourth threshold, the paging PDCCH determined by the network device is the second type of paging PDCCH. Taking the fourth threshold of 30km as an example, when the network device is in the city center, the paging PDCCH determined by the network device is the second type of paging PDCCH; when the network device is in the suburbs 40km away from the city center, the paging PDCCH determined by the network device is the first type of paging PDCCH. Alternatively, the network device is classified as belonging to an area with a low population density or as belonging to an area with a high population density according to its location. The paging PDCCH determined by the network device classified as belonging to an area with a low population density is the first type of paging PDCCH, and the paging PDCCH determined by the network device classified as belonging to an area with a high population density is the second type of paging PDCCH.

[0126] Mode 5: The network device determines the paging PDCCH according to the status of the terminal to be paged.

[0127] In one possible implementation, when the terminal to be paged is in an inactive state, the network device determines to page the terminal using a first type of paging PDCCH. When the terminal to be paged is in an idle state or a connected state, the network device determines to page the terminal using a second type of paging PDCCH.

[0128] It is understandable that when the terminal is in an inactive state, the network device determines the terminal's paging identifier based on the I-RNTI. When the terminal is in an idle state or a connected state, the network device determines the terminal's paging identifier based on the 5G-S-TMSI. The paging identifier is an identifier used by the network device when paging the terminal, for example, a first type identifier or a second type identifier. The bit size of the I-RNTI is 41 bits, and the bit size of the 5G-S-TMSI is 48 bits. The bit size of the I-RNTI is smaller than that of the 5G-S-TMSI. Therefore, if the paging identifier is determined based on the I-RNTI, using the first type of paging PDCCH to paging the terminal will generally not cause the terminal to be mis-paged. In this case, the network device determines to use the first type of paging PDCCH to paging the terminal. However, the 5G-S-TMSI bit size is relatively large, and when the paging PDCCH payload size is small, it may cause the terminal to be mis-paged. In this case, the network device determines to use the second type of paging PDCCH to paging the terminal.

[0129] Method 6: The network device determines the paging PDCCH according to the paging identifier.

[0130] Exemplarily, when the paging identifier of the terminal to be paged is I-RNTI, the network device determines to page the terminal via the first type of paging PDCCH. When the paging identifier of the terminal to be paged is 5G-S-TMSI, the network device determines to page the terminal via the second type of paging PDCCH.

[0131] Method 7: The network device determines the paging PDCCH according to the second type of identifier and the paging PDCCH payload size.

[0132] In one possible implementation, if the bit position obtained by adding N bits of the paging type indication information to the bit position of the second type identifier minus the L bits used to determine the paging opportunity in the second type identifier is less than or equal to the PDCCH payload size, the network device determines to page the terminal via the first type of paging PDCCH. When the bit position obtained by adding N bits of the paging type indication information to the bit position of the second type identifier minus the L bits used to determine the paging opportunity in the second type identifier is greater than the PDCCH payload size, the network device determines to page the terminal via the second type of paging PDCCH.

[0133] For example, taking the second type of identifier as I-RNTI, L as 10 bits, and N as 1 bit as an example, 41-10+1=32 bits. If the payload size of the paging PDCCH is 37 bits and 32<37, the network device determines to use the first type of paging PDCCH. Taking the second type of identifier as 5G-S-TMSI, L as 10 bits, and N as 1 bit as an example, 48-10+1=39 bits. If the payload size of the paging PDCCH is 37 bits and 39>37, the network device determines to use the second type of paging PDCCH.

[0134] It is understandable that if the paging type indication information is not included in the paging PDCCH, the network device does not refer to the N bits of the paging type indication information when determining the paging PDCCH. Exemplarily, if the bit position of the second type of identifier, minus the bit position obtained by subtracting the L bits used to determine the paging opportunity in the second type of identifier, is less than or equal to the PDCCH payload size, the network device determines to page the terminal through the first type of paging PDCCH. When the bit position of the second type of identifier, minus the bit position obtained by subtracting the L bits used to determine the paging opportunity in the first type of identifier, is greater than the PDCCH payload size, the network device determines to page the terminal through the second type of paging PDCCH.

[0135] It is understandable that a network device may determine different types of paging PDCCHs for different terminals. For example, the paging PDCCH determined by the network device for terminal 1 is a first type of paging PDCCH, and the paging PDCCH determined for terminal 2 is a second type of paging PDCCH.

[0136] It is understandable that the embodiments of the present application do not limit the number of paging PDCCHs determined by the network device. In other words, the number of paging PDCCHs determined by the network device can be one or more. When the number of paging PDCCHs determined by the network device is multiple, the multiple paging PDCCHs can all be paging PDCCHs of the first type, can all be paging PDCCHs of the second type, or can include both paging PDCCHs of the first type and paging PDCCHs of the second type.

[0137] It should be noted that before step 301, the network device may also receive information indicating the type of paging PDCCH from the terminal. The information indicating the type of paging PDCCH is used to indicate the type of paging PDCCH supported by the terminal. In this way, the network device can determine the paging method for the terminal as needed.

[0138] Step 302: The network device sends a paging PDCCH to the terminal.

[0139] The terminal can be Figure 1For example, the terminal is Figure 1 Terminal 102, and / or, terminal 103, and / or, terminal 104.

[0140] Correspondingly, the terminal receives a paging PDCCH from the network device.

[0141] Step 303: The terminal determines whether it is paged according to the paging PDCCH.

[0142] It is understandable that before determining whether it is paged, the terminal needs to determine the type of the received paging PDCCH. For example, the terminal can determine the type of the paging PDCCH by the following three methods:

[0143] Method 1: The terminal determines the type of paging PDCCH according to the scrambling method.

[0144] In one possible implementation method, the scrambling methods of the first type of paging PDCCH and the second type of PDCCH are different. When the terminal descrambles the paging PDCCH, if the paging PDCCH is descrambled using the scrambling method corresponding to the first type of paging PDCCH, the terminal determines that the received paging PDCCH is the first type; if the paging PDCCH is descrambled using the scrambling method corresponding to the second type of paging PDCCH, the terminal determines that the received paging PDCCH is the second type.

[0145] Method 2: The terminal determines the type of the paging PDCCH according to the above-mentioned paging type indication information.

[0146] In one possible implementation, if the paging PDCCH includes paging type indication information, the terminal determines the type of the paging PDCCH based on the paging type indication information. For example, if the paging type indication information is 1, the terminal determines that the received paging PDCCH is the first type; if the paging type indication information is 0, the terminal determines that the received paging PDCCH is the second type, and vice versa.

[0147] Method 3: The terminal determines the type of paging PDCCH through a notification message sent by a network device.

[0148] In a possible implementation, before step 302, the terminal receives a notification message indicating the type of the paging PDCCH from the network device, and then determines the type of the paging PDCCH according to the notification message. Figure 6 It can be understood that, for mode 3, the paging PDCCH may not include the above-mentioned paging type indication information, and / or the scrambling mode of the first type of paging PDCCH and the second type of paging PDCCH is the same.

[0149] It can be understood that after determining the type of the paging PDCCH, the terminal can parse the paging PDCCH, thereby determining whether the terminal is paged according to the paging PDCCH.

[0150] In one possible implementation, when the paging PDCCH is a first type of paging PDCCH, the terminal determines whether to be paged based on the first type of paging PDCCH; when the paging PDCCH is a second type of paging PDCCH, the terminal receives the paging PDSCH based on the second type of paging PDCCH; and the terminal determines whether to be paged based on the paging PDSCH.

[0151] Furthermore, the terminal determines whether it is paged based on the first type of paging PDCCH, including: if the first type of paging PDCCH includes the terminal's identifier, determining that the terminal is paged; if no paging PDCCH within the paging opportunity where the paging PDCCH is located does not include the terminal's identifier, determining that the terminal is not paged. The terminal identifier may also be replaced with the first type of identifier corresponding to the terminal.

[0152] It can be understood that if the paging PDCCH is the second type of paging PDCCH, the terminal also needs to receive the paging PDSCH from the network device according to the frequency domain resource indication and time domain resource indication in the second type of paging PDCCH, and then determine whether the terminal is paged according to the paging PDSCH.

[0153] The paging PDSCH includes an identifier of at least one terminal.

[0154] Furthermore, the terminal determines whether it is paged according to the paging PDSCH, including: if the paging PDSCH includes the terminal's identifier, determining that the terminal is paged; if the paging PDSCH does not include the terminal's identifier, determining that the terminal is not paged.

[0155] based on Figure 3 In the method shown, the network device can determine the paging PDCCH and send the paging PDCCH to the terminal. After receiving the PDCCH, the terminal determines the type of the PDCCH. When the paging PDCCH is a first type of paging PDCCH, it determines whether the terminal is paged based on the first type of paging PDCCH; when the paging PDCCH is a second type of paging PDCCH, it receives the paging PDSCH and determines whether the terminal is paged based on the paging PDSCH. In this way, the terminal can be compatible with the first type of paging PDCCH and the second type of paging PDCCH. The network device can also determine the method of paging the terminal as needed, rather than using only a single method to page the terminal.

[0156] exist Figure 3In a possible implementation of the method shown, the network device sends a notification message to the terminal to indicate the type of the paging PDCCH sent by the subsequent network device. After receiving the notification message, the terminal can determine the type of the paging PDCCH received by the terminal based on the notification message. Specifically, Figure 6 As shown, Figure 3 The method shown further includes step 601 and step 602 .

[0157] Step 601: The network device sends a notification message to the terminal.

[0158] The notification message is used to indicate the type of the paging PDCCH. For example, the notification message includes 1 bit of information. When the 1 bit of information is 1, the notification message indicates that the type of the paging PDCCH is the first type of paging PDCCH. When the 1 bit of information is 0, the notification message indicates that the type of the paging PDCCH is the second type of paging PDCCH, and vice versa.

[0159] Furthermore, the notification message is used to indicate the number Q of paging PDCCHs that can be detected in one paging opportunity, where Q is a positive number. Thus, after the terminal detects Q paging PDCCHs in one paging opportunity, the terminal can stop detecting paging PDCCHs to reduce power consumption of the terminal.

[0160] In a possible implementation manner, the notification message is a higher layer signaling, for example, a radio resource control (RRC) layer signaling.

[0161] It is understandable that the above Q may also be predefined. For example, the above Q may be defined in the protocol.

[0162] Step 602: The terminal determines the type of the paging PDCCH according to the notification message.

[0163] For example, taking the notification message including 1-bit information as an example, if the 1-bit information is 1, the terminal determines that the type of paging PDCCH is the first type of paging PDCCH; if the 1-bit information is 0, the terminal determines that the type of paging PDCCH is the second type of paging PDCCH, and vice versa.

[0164] It should be noted that the above steps 601 and 602 may also be performed before step 301 without limitation.

[0165] based on Figure 6In the method shown, the network device can send a notification message to the terminal to indicate the type of the paging PDCCH. After receiving the notification message, the terminal can determine the type of the paging PDCCH based on the notification message. In this way, after receiving the paging PDCCH, the terminal can correctly interpret the paging PDCCH.

It can be understood that in order to realize the above functions, the above-mentioned network devices or terminals, etc. include hardware structures and / or software modules corresponding to the execution of each function. Those skilled in the art should easily realize that, in combination with the units and algorithm operations of the various examples described in the embodiments disclosed herein, the present application can be implemented in the form of hardware or a combination of hardware and computer software. Whether a function is executed in the form of hardware or computer software driving hardware depends on the specific application and design constraints of the technical solution. Professional and technical personnel can use different methods to implement the described functions for each specific application, but such implementation should not be considered to be beyond the scope of this application.

[0167] The embodiments of the present application can divide the network device or terminal into functional modules according to the above method examples. For example, each functional module can be divided according to each function, or two or more functions can be integrated into one processing module. The above integrated modules can be implemented in the form of hardware or in the form of software functional modules. It should be noted that the division of modules in the embodiments of the present application is schematic and is only a logical function division. In actual implementation, there may be other division methods.

[0168] For example, when the functional modules are divided in an integrated manner, Figure 7 The schematic diagram of the structure of a communication device is shown.

[0183] In one possible implementation, the second type of identifier is 5G-S-TMSI or I-RNTI.

[0184] A possible implementation method is that when the paging PDCCH is a first type of paging PDCCH, the number of terminals to be paged within the paging opportunity where the paging PDCCH is located is less than or equal to a first threshold; or, the service coverage of the network device is less than or equal to a second threshold; or, the traffic volume of the network device is less than or equal to a third threshold; the distance between the location of the network device and the location of the city center is greater than or equal to a fourth threshold; or, the terminal to be paged is in an inactive state; or, the paging identifier of the terminal to be paged is I-RNTI.
