Description

Paging method and communication device Technical Field

[0001] The present application relates to the field of communication technology, and more specifically, to a paging method and a communication device. Background Art

[0002] In both LTE and NR systems, core network-triggered paging information is sent by the access network equipment to the terminal device via the physical downlink shared channel (PDSCH). The access network equipment indicates the transmission resources of the PDSCH to the terminal device using a Paging-Radio Temporary Identity scrambled physical downlink control channel.

[0003] To reduce network-side energy consumption, a communication system design is currently being proposed that separates signaling from data. This involves dividing access network equipment into data access network equipment and signaling access network equipment. Data access network equipment focuses on user plane processing and can be powered on when data is being transmitted and powered off when it is not, thereby achieving energy savings. Signaling access network equipment focuses on signaling plane processing, providing wide-area signaling coverage and maintaining always-on connectivity.

[0004] When a signaling access network device is paging a terminal device, the corresponding data access network device may be in a dormant state due to no data transmission. To enable the data access network device to provide data transmission services to the terminal device, the terminal device needs to wake it up by sending a wake-up signal. However, this approach may increase overall latency.

[0005] Summary of the Invention

[0006] The present application provides a paging method and a communication device, which can achieve simultaneous paging of a terminal device and a network device capable of providing services to the terminal device, thereby reducing the overall delay.

[0007] In a first aspect, a paging method is provided, including: a first communication device receives a paging message from a third communication device, the paging message including first indication information, the first indication information being used to indicate the first communication device and the second communication device, the second communication device providing a service for the first communication device, or the first communication device providing a service for the second communication device; the first communication device establishes a connection with the second communication device or the third communication device according to the paging message.

[0008] The first communication device may be a terminal device 120, or a chip in the terminal device 120, or a device used in conjunction with the terminal device 120. The second communication device may be a network device 130 capable of providing services for the terminal device 120, or a chip in the network device 130, or a device used in conjunction with the network device 130. Alternatively, the second communication device may be the terminal device 120, and the first communication device may be the network device 130 capable of providing services for the terminal device 120. The third communication device may be a network device 110, which is used to provide relevant configurations for the aforementioned terminal device 120.

[0009] The first communication device establishes a connection with the second communication device or the third communication device based on the paging information, which may specifically include the first communication device establishing a first connection based on the paging information. The first connection may be a connection between the first communication device and the second communication device, or may be a connection between the first communication device and the third communication device.

[0010] By carrying indication information for indicating the terminal device and the network device that provides services for the terminal device in the paging information, the present application can achieve simultaneous paging of the terminal device and the network device that can provide services for the terminal device, thereby reducing the overall delay.

[0011] In a possible implementation, the first indication information includes a first identifier and a second identifier, wherein the first identifier is used to indicate the first communication device, and the second identifier is used to indicate the second communication device.

[0012] Specifically, by including a first identifier and a second identifier in a paging message, a first communication device, upon receiving the paging message, can determine that the paging message is relevant to it using the first identifier. Correspondingly, a second communication device, upon receiving the paging message, can determine that the paging message is relevant to it using the second identifier. In this way, the present application can achieve simultaneous paging of a terminal device and a network device capable of providing services to the terminal device, thereby reducing overall latency.

[0013] In a possible implementation manner, the first indication information includes an index, where the index associates the first communication device with the second communication device.

[0014] There is a mapping relationship between the index and the first communication device and the second communication device. The mapping relationship may be pre-configured or pre-defined by a protocol. The first communication device or the second communication device may determine whether the paging information is relevant to it based on the received index and the mapping relationship.

[0015] Optionally, the index may associate the identifier of the first communication device with the identifier of the second communication device.

[0016] Optionally, the embodiment of the present application does not limit the specific form of the index.

[0017] By adopting the index that associates the first communication device and the second communication device, the embodiment of the present application can save signaling overhead for paging the first communication device and the second communication device at the same time.

[0018] In one possible implementation, the paging information further includes beam information for communication between the first communication device and the second communication device.

[0019] The above implementation method can enable the first communication device to quickly achieve beam alignment with the second communication device, thereby reducing access delay.

[0020] In a possible implementation, the transmission resource used by the first communication apparatus to receive the paging information is the same as the transmission resource used by the second communication apparatus to receive the paging information.

[0021] Specifically, the first communication device and the second communication device receive the paging information at the same transmission resource, which can be represented as the first communication device and the second communication device sharing the same paging configuration information. In this way, the embodiment of the present application can save signaling overhead.

[0022] In one possible implementation, the second communication device provides a service for the first communication device. Before the first communication device receives a paging message from the third communication device, the method further includes:

[0023] The first communication device receives second indication information from a third communication device, where the second indication information is used to indicate at least one control resource set; the first communication device determines a first control resource set in at least one resource control set based on parameters of the first communication device; there is an association between the parameters of the first communication device and the first control resource set; each control resource set in the at least one control resource set is used to receive downlink control information, where the downlink control information is used to indicate a transmission resource for receiving the paging information.

[0024] By indicating multiple control resource sets for receiving downlink control information to the first communication device, the first communication device can select an appropriate control resource set based on the parameters, thereby avoiding blind detection on multiple control resource sets at the same time, which can reduce the complexity of the first communication device.

[0025] In addition, by configuring multiple control resource sets for monitoring downlink control information, the embodiment of the present application can solve the problem of insufficient control channel resources for monitoring downlink control information, thereby enhancing the paging capacity.

[0026] In a possible implementation manner, the association relationship between the parameters of the first communication device and the first control resource set is predefined by a protocol, or the association relationship between the parameters of the first communication device and the first control resource set is indicated.

[0027] For example, the third communication device sends indication information to the first communication device, which is used to indicate the association relationship between the parameters of the first communication device and the first control resource set.

[0028] By adopting the indication method, the embodiment of the present application can more flexibly indicate to the first communication device the association relationship between the parameters of the first communication device and the first control resource set. By adopting the protocol predefined method, the embodiment of the present application can reduce notification overhead.

[0029] In a possible implementation manner, the parameter of the first communication device includes at least one of the following: a group identifier, a device identifier, or a beam index.

[0030] The first communication device may determine an appropriate control resource set based on the above parameters, thereby reducing the complexity of the first communication device in determining the corresponding control resource set.

[0031] For example, when the parameters of the first communication device include a beam index, the first communication device can directly determine the corresponding control resource set based on the synchronization signal block beam index. Additionally, adjacent synchronization signal block beam indices can be associated with different control resource sets (e.g., different frequency domain locations), thereby reducing interference.

[0032] In a possible implementation, the downlink control information is further used to indicate at least one of the following: system message change, earthquake and tsunami warning system information, commercial mobile early warning system message, or notification to stop paging detection.

[0033] In a second aspect, a paging method is provided, including: a first communication device receives configuration information from a third communication device, the configuration information is used to configure a first transmission resource and at least one second transmission resource, wherein the first transmission resource is used to receive downlink control information, the second transmission resource is used to receive paging information, and the downlink control information is used to indicate reception of the paging information; the first communication device receives the downlink control information from the third communication device and the paging information from the second communication device according to the configuration information.

[0034] Specifically, the first communication device receives downlink control information and paging information from different communication devices respectively according to the configuration information sent by the third communication device. In this way, the embodiment of the present application can enable the first communication device to receive paging information on a transmission resource different from the transmission resource used to receive downlink control information. In this way, the problem of insufficient physical downlink shared channel resources for sending paging information can be overcome.

[0035] Specifically, the first communication device can receive paging information based on the second transmission resource, and the downlink control information received based on the first transmission resource is used to indicate the reception of paging information. In this way, it can overcome the existing limitation that the resources used to receive paging information cannot exceed the size of control resource set #0, and then increase the transmission resources used to transmit paging information.

[0036] In a possible implementation manner, a carrier corresponding to the first transmission resource is different from a carrier corresponding to the second transmission resource.

[0037] In this way, cross-carrier scheduling of paging information can be supported.

[0038] In a possible implementation, the configuration information includes at least one of the following: a cell identifier corresponding to the second transmission resource, a starting position and size of the second transmission resource, a resource number of the second transmission resource, or a carrier number of the second transmission resource.

[0039] The first communication device may determine more detailed information about the second transmission resource based on the above information, so that the first communication device can receive paging information on the second transmission resource.

[0040] In a possible implementation manner, the cell identifier used to scramble the first transmission resource is different from the cell identifier used to scramble the second transmission resource.

[0041] By using different cell identifiers to scramble different transmission resources, the embodiments of the present application can support the reuse of current implementation methods, thereby reducing the implementation complexity of cross-carrier scheduling scenarios for paging information.

[0042] In a possible implementation, the method further includes: the first communication device receiving third indication information from a third communication device, where the third indication information is used to indicate whether the quasi-co-location of the first transmission resource is the same as the quasi-co-location of the second transmission resource.

[0043] Specifically, the first communications device may determine, based on whether the quasi-co-location of the first transmission resource and the second transmission resource indicated by the third indication information is the same, whether the quasi-co-location information used to receive downlink control information can be reused when receiving paging information. For example, if they are the same, the quasi-co-location information used to receive downlink control information can be reused; if they are not the same, the quasi-co-location information used to receive downlink control information is not reused.

[0044] In a possible implementation, the method further includes: the first communication device receiving fourth indication information from the third communication device, where the fourth indication information is used to indicate beam information for communication between the first communication device and the second communication device.

[0045] Specifically, the first communication device receives downlink control information and paging information from different communication devices. The first communication device can determine the beam information used to receive the paging information through the above-mentioned fourth indication information, that is, the indication information indicates what kind of beam the first communication device should use to receive the paging information, thereby avoiding not receiving the paging information.

[0046] In a possible implementation, the third indication information or the fourth indication information is further used to indicate at least one of the following: the number of time units between the first transmission resource and the second transmission resource, or the cyclic prefix length of the second transmission resource.

[0047] By indicating the time delay between the first transmission resource and the second transmission resource, the embodiment of the present application can enable the first communication device to receive the second transmission resource at an appropriate time, thereby avoiding the situation where the first communication device fails to receive the paging information in advance. In addition, this can also reduce the energy consumption of the first communication device.

[0048] In one possible implementation, the time unit includes at least one of the following: a time slot, a mini-slot, a non-slot, or a symbol.

[0049] For example, the new air interface wireless communication system supports the scheduling of mini-slots, which can start from any orthogonal frequency division multiplexing (OFDM) symbol in a time slot. A downlink mini-slot can be 2, 4, or 7 OFDM symbols, and an uplink mini-slot can be any length within 1-14 OFDM symbols. A mini-slot can also be referred to as a non-slot.

The chip system in the embodiments of the present application can be composed of a chip, or can include a chip and other discrete devices.

[0169] Figure 1 is a schematic diagram of a communication system 100 applicable to an embodiment of the present application. As shown in Figure 1, the communication system 100 includes a network device 110, multiple terminal devices 120, and multiple network devices 130. Furthermore, the embodiment of the present application does not limit the number of terminal devices and network devices included in the communication system 100. It is worth noting that the schematic diagram shown in Figure 1 is intended for illustrative purposes only and does not limit the scope of protection claimed by this application.

[0170] It is understandable that the terminal device 120 shown in FIG. 1 may be any terminal device listed above, and the network device 110 and the network device 130 may also be any network device listed above.

[0171] In the above-described communication system 100, the network device 110 may be a wide-coverage base station (e.g., a signaling base station) configured to provide signaling services to terminal devices within the coverage area of ​​the network device 110. In addition to being connected to the network device 110, the terminal device 120 may also be connected to the network device 130. The network device 130 may be a small-coverage base station (e.g., a data base station, a normal base station, or a small base station) configured to provide services, such as data transmission services, to terminal devices within the coverage area of ​​the network device 130. The services may be enabled or disabled based on the need for the services, thereby achieving energy conservation.

[0172] The existing paging process is described below.

[0173] FIG2 is a flow chart of an existing paging method 200. As shown in FIG2 , the execution body of the paging method 200 includes a terminal device and an access network device. The paging method 200 includes:

[0174] S210. The access network device sends downlink control information scrambled by the paging-radio network temporary identifier to the terminal device.

[0175] Accordingly, the terminal device receives downlink control information (DCI) scrambled by a paging radio network temporary identifier (P-RNTI) from the access network device.

[0176] For terminal devices in idle state, they need to periodically wake up and monitor the P-RNTI-encrypted physical downlink control channel (PDCCH) and parse the DCI carried by the PDCCH. In addition to being used to indicate short messages to terminal devices, the P-RNTI-encrypted DCI can also be used to schedule transmission resources for the physical downlink shared channel (PDSCH) that carries paging messages.

[0177] Specifically, the terminal device can determine that the received P-RNTI-scrambled DCI is a paging indication, and can also determine the transmission resources of the PDSCH for receiving the paging information based on the P-RNTI-scrambled DCI.

[0178] S220: The access network device sends a paging message to the terminal device.

[0179] Correspondingly, the terminal device receives paging information from the access network device.

[0180] The terminal device can determine the transmission resource of the PDSCH used to receive the paging information according to the DCI scrambled by the P-RNTI it has received, and receive the paging information from the access network device at the transmission resource of the PDSCH.

[0181] Furthermore, the terminal device can parse and obtain the content of the paging information.

[0182] From the above, the terminal device and the access network device complete the paging process.

[0183] Specifically, paging is the process of finding or waking up a terminal device. Paging processes can be categorized into two types: those triggered by the core network (CN) and those triggered by access network devices. The following section focuses on the core network-triggered paging process.

[0184] The paging information triggered by the core network needs to be sent to the terminal device through the access network device. For example, the core network sends the paging information to the access network device through the NG interface, and the access network device then sends it to the terminal device.

[0185] In both LTE and NR systems, core network-triggered paging information is sent to terminal devices via the PDSCH by the access network equipment. The PDSCH transmission resources are indicated to the terminal device by the access network equipment using the P-RNTI-scrambled PDCCH. Therefore, before receiving paging information, the terminal device must first monitor the PDCCH channel and determine whether paging information is being sent within the paging cycle based on whether the PDCCH carries the P-RNTI DCI.

[0186] In order to reduce the power consumption of terminal devices in the radio resource control_idle state (RRC_IDLE) / inactive state (RRC_INACTIVE), the terminal device will use discontinuous reception (DRX) to receive paging information. Among them, a DRX cycle includes at least one paging frame (PF). A PF corresponds to at least one paging occasion (PO). The terminal device only needs to wake up once in a DRX cycle to monitor a PO. In addition, the DRX cycle indicates the period in which the terminal device detects paging, the PF indicates the system frame in which the terminal device detects paging, and the PO indicates the specific PDCCH monitoring occasions (monitioring occasions) in which the terminal device detects paging.

[0187] The terminal device can calculate and determine the position of PF and PO through relevant formulas. For example,

[0188] PF: (SFN+PF_offset)mod T=(T div N)*(UE_ID mod N);

[0189] i_s:floor(UE_ID / N)mod N S =0.

[0190] SFN represents the system frame number (SFN). T represents the DRX cycle. Generally, there is a cell-level T in the system information. c At the same time, there may also be UE-level T UE If there is no indication T UE , then T=T UE ; If T is indicated UE , then T=min{T c , T UE}. N represents the total number of PFs in T. N SIndicates the number of POs corresponding to a PF. PF_offset indicates the offset of the PF. UE_ID indicates the remainder of the UE's international mobile subscriber identifier (IMSI) modulo 1024, where mod is a modulo operation. floor indicates a function that rounds down. i_s indicates the index of the PO corresponding to the PF.

[0191] It is understood that the access network device can broadcast configuration information related to paging through the paging control channel (PCCH)-configuration information (Config) in the system information block (SIB). For example, the configuration information related to paging may include: paging cycle (DRX cycle), PF offset within the paging cycle, the starting position of PO, etc. Based on the above configuration information and the identification information of the terminal device, the terminal device determines the corresponding PO within each paging cycle. For an example of the content of the configuration information, please refer to Table 1.

[0192] Table 1

[0193]

[0194] Based on the content shown in Table 1, it can be concluded that the terminal device needs to wake up once every 320ms (T*10ms) and attempt to receive paging information. During the DRX cycle, one PF will be used to send paging information in every two system frames (N=16). Different terminal devices can select a corresponding PO from the 16 POs in the DRX cycle based on their different UE_IDs to receive paging information.

[0195] In the scenario shown in Figure 1, in order to reduce network-side energy consumption while keeping user services online, the network device 110 used to provide signaling services to the terminal device 120 needs to remain online. The network device 130 that provides data transmission services to the terminal device 120 is turned on when there is data transmission and turned off when there is no data transmission. Among them, the network device 130 can support multiple modes, such as: active state, dormant state, uplink transmission only (UL only) state, etc. When there are no terminal devices in the connected state (RRC-CONNECTED) within the coverage area of ​​the network device 130, the network device 130 can enter the dormant state. At this time, the paging operation is performed by the network device 110. When the network device 110 performs the operation of paging the terminal device 120, if the terminal device 120 to be paged is within the coverage area of ​​the network device 130 in the dormant state, after the terminal device 120 is awakened, it needs to wake up the corresponding network device 130 in the dormant state so that it can provide data transmission services to the terminal device 120.

[0196] However, the paging method in which the network device 110 first wakes up the terminal device 120 and then the terminal device 120 wakes up the corresponding network device 130 will cause the startup time of the network device 130 to be later and increase the overall delay.

[0197] In view of the above technical problems, the present application provides a paging method and a communication device. By carrying indication information for indicating a terminal device and a network device that can provide services for the terminal device in the paging information, the present application can achieve simultaneous paging of the terminal device and the network device that can provide services for the terminal device, thereby reducing the overall delay.

[0198] The paging method according to the embodiment of the present application will be described below with reference to the accompanying drawings.

[0199] FIG3 is an interactive flow chart of a paging method 300 according to an embodiment of the present application. The method flow in FIG3 can be executed by the first communication device / third communication device, or by a module and / or device (e.g., a chip or integrated circuit, etc.) with corresponding functions installed in the first communication device / third communication device, and is not limited in the embodiment of the present application. The following description will be made using the first communication device / third communication device as an example. The execution entities of the paging method 300 are the first communication device and the third communication device. Among them, the third communication device can be the network device 110.

[0200] It is understandable that in the paging method 300, the first communication device may be a terminal device 120, and the second communication device may be a network device 130. Alternatively, the first communication device may be a network device 130, and the second communication device may be a terminal device 120. Therefore, the paging method 300 is not only applicable to the scenario where the first communication device is a terminal device 120 and the second communication device is a network device 130, but also to the scenario where the first communication device is a network device 130 and the second communication device is a terminal device 120. For ease of description, the embodiment of the present application is described by taking the first communication device as the terminal device 120 as an example, but is not limited to the scenario where the first communication device is the network device 130. As shown in Figure 3, the paging method 300 includes:

[0201] S310. The third communication device sends a paging message #A to the first communication device, including first indication information, used to indicate the first communication device and the second communication device.

[0202] Accordingly, the first communication device receives the paging message #A from the third communication device.

[0203] Specifically, the paging information #A sent by the third communication device to the first communication device includes first indication information, which is used to indicate the first communication device and the second communication device.

[0204] In one possible implementation, when the first communication device is a terminal device 120, the second communication device is a network device 130, and the second communication device can be used to provide services for the first communication device, for example, the second communication device provides data transmission services for the first communication device, or the second communication device provides data forwarding services for the first communication device, and so on.

[0205] In addition, the second communication device is used to provide services for the first communication device, which can be understood as: the second communication device is an associated communication device of the first communication device, that is, the first communication device and the second communication device are associated with each other.

[0206] Among them, the association relationship between the second communication device and the first communication device can be configured by the core network, or by a third communication device, or can be formed based on the historical resident information of the first communication device, or through the interaction between the second communication devices and their associated first communication devices.

[0207] When the second communication device provides services for the first communication device, the second communication device may be referred to as a service node, and the service node may be any one of a base station, a cell, a TRP, a RIS node, an IAB node, and a relay node.

[0208] In one aspect, the first indication information included in the paging message #A can be used to indicate to the first communications device that the paging message #A is relevant to the first communications device. After receiving the paging message related to the first communications device, the first communications device can perform one or more of the following operations: responding to the paging message #A, restoring the RRC connection, re-establishing the RRC connection, etc.

[0209] On the other hand, the first indication information included in the paging message #A can also be used to indicate to the second communication device that the paging message #A is related to the second communication device. After receiving the paging message related to it, the second communication device can perform one or more of the following operations: switching to an awake state, responding to the paging message #A, or providing data transmission services to the first communication device, etc.

[0210] In summary, the paging message #A sent by the third communication device to the first communication device can be used not only to page the first communication device, but also to page the second communication device. The third communication device can simultaneously page the first and second communication devices by broadcasting the paging message #A. Specifically, the third communication device can also send the paging message #A to the second communication device. The third communication device can simultaneously broadcast the paging message #A to both the first and second communication devices.

[0211] In one possible implementation, the first indication information includes a first identifier and a second identifier. The first identifier may be a device identifier (e.g., UE_ID) of the first communication device, which is used to indicate the first communication device. The second identifier may be a device identifier, a cell identifier (e.g., CELL_ID), or a network-configured node identifier (e.g., an identifier configured by the third communication device for the second communication device when the second communication device establishes a link with the third communication device) of the second communication device, etc., which is used to indicate the second communication device.

[0212] Specifically, by including a first identifier and a second identifier in a paging message, a first communication device, upon receiving the paging message, can determine that the paging message is relevant to it using the first identifier. Correspondingly, a second communication device, upon receiving the paging message, can determine that the paging message is relevant to it using the second identifier. In this way, the present application can achieve simultaneous paging of a terminal device and a network device capable of providing services to the terminal device, thereby reducing overall latency.

[0213] Optionally, when the first indication information in the paging information #A includes the first identifier and the second identifier, it can be understood that the paging information #A includes the first identifier and the second identifier.

[0214] In one possible implementation, paging information #A may include an identifier list including multiple identifiers. Furthermore, the identifier list may include an identifier list for a first communication device and an identifier list for a second communication device. Specifically, the identifier list for the first communication device includes multiple identifiers indicating different first communication devices. The identifier list for the second communication device includes multiple identifiers indicating different second communication devices.

[0215] In one possible implementation, the first indication information includes a first identifier list and a second identifier list, wherein each first identifier in the first identifier list indicates a first communication device, and each second identifier in the second identifier list indicates a second communication device.

[0216] Optionally, one first identifier is associated with multiple second identifiers, that is, one first communication device is associated with one or more second communication devices. In this way, multiple first communication devices and second communication devices can be woken up simultaneously.

[0217] In one possible implementation, the first indication information includes an index that associates the first communication device with the second communication device. Exemplarily, the index associates an identifier of the first communication device (eg, a first identifier) ​​with an identifier of the second communication device (eg, a second identifier).

[0218] The index can be considered as a connection relationship established by the third communication device between the first communication device and the second communication device. The third communication device reflects the association relationship between the first communication device and the second communication device in the form of an index, and the association relationship between the first communication device and the second communication device can be configured in a manner predefined by the protocol.

[0219] For example, index #a is associated with identifier #a1 and identifier #b1, index #b is associated with identifier #a2 and identifier #b2, and index #c is associated with identifier #a3 and identifier #b3. A first communication device can determine that paging information #A is associated with the first communication device based on the received index #a and its own identifier #a1. A second communication device can determine that paging information #A is associated with the second communication device based on the received index #a and its own identifier #b1. Thus, by employing an indexing approach, embodiments of the present application can reduce signaling overhead.

[0220] Optionally, the index may include the identifier of the first communication device or the identifier of the second communication device. That is, paging message #A includes the identifier of the first communication device or the identifier of the second communication device, and the identifier of the first communication device is associated with the identifier of the second communication device. This association may be predefined by the protocol or configured in advance. After receiving paging message #A, the first communication device or the second communication device can determine whether paging message #A is relevant to it based on the identifier of the first communication device or the identifier of the second communication device and this association.

[0221] Furthermore, the paging information #A may include an index list, which includes multiple indexes, for example, the above-mentioned index #a, index #b, index #c, etc.

[0222] Optionally, the embodiment of the present application does not limit the specific form of the index.

[0223] By adopting the index that associates the first communication device and the second communication device, the embodiment of the present application can save signaling overhead for paging the first communication device and the second communication device at the same time.

[0224] Optionally, the association relationship between the first communication device and the second communication device may be determined by the third communication device indicating to the first communication device and the second communication device.

[0225] Exemplarily, for example, when the first communication device accesses the third communication device, the third communication device indicates to the first communication device the index value corresponding to the association relationship between the first communication device and the second communication device; or, when the first communication device enters the RRC_IDLE state, the third communication device indicates to the first communication device the index value corresponding to the association relationship between the first communication device and the second communication device, and so on.

[0226] In one possible implementation, the first indication information includes an index and a first identifier. In this way, the first communication device can determine that the paging information #A is related to it based on the first identifier. The second communication device can also determine that the paging information #A is related to it based on the first identifier and the index.

[0227] S320. The first communication device establishes a connection with the second communication device or the third communication device according to the paging information #A.

[0228] Specifically, when the first communication device is terminal device 120 and the second communication device is network device 130, the first communication device can determine that it is related to the first communication device through the first indication information in paging message #A. Therefore, the first communication device can respond to paging message #A. For example, the first communication device restores the RRC connection with the third communication device, or the first communication device re-establishes the RRC connection with the third communication device, etc. For another example, the first communication device establishes an air interface connection with the second communication device.

[0229] The first communication device establishing a connection with the second communication device or the third communication device based on the paging information may include: the first communication device establishing a first connection based on the paging information. The first connection may be a connection between the first communication device and the second communication device, or a connection between the first communication device and the third communication device. This is explained here and will not be repeated below.

[0230] In summary, the first communication device can establish a connection with the second communication device or the third communication device according to the paging information #A.

[0231] By carrying indication information for indicating the first communication device and the second communication device associated with the first communication device in the paging information, the third communication device can wake up the first communication device and the second communication device at the same time, thereby reducing the overall delay and saving paging overhead.

[0232] In some possible implementations, the third communication device can obtain the location information of the first communication device (terminal device), for example: the location of the first communication device (terminal device) is fixed, for example: the third communication device can obtain the location information of the first communication device (terminal device) based on artificial intelligence, perception, etc., and can infer one or more second communication devices that may be associated with the first communication device (terminal device) based on the location information.

[0233] In some possible implementations, due to the mobility of the first communication device (terminal device), the third communication device may not be able to obtain the specific location information of the first communication device (terminal device) in real time, but it can infer one or more second communication devices that may be associated with the first communication device (terminal device) based on the acquired historical location information and movement route of the first communication device (terminal device).

[0234] In a possible implementation, the third communication device places the identifiers of multiple second communication devices associated with the first communication device in the paging information #A to simultaneously wake up the first communication device and the multiple second communication devices associated with it.

[0235] The number of second communication devices associated with the first communication device may be one or more. When multiple second communication devices are involved, the aforementioned first indication information can be used to indicate multiple second communication devices.

[0236] A possible implementation:

[0237] The transmission resource used by the third communication apparatus to send the paging information #A to the first communication apparatus is the same as the transmission resource used by the third communication apparatus to send the paging information #A to the second communication apparatus.

[0238] For example, the first communication device and the second communication device monitor paging information #A on the same transmission resource. In other words, the first communication device and the second communication device share the same paging configuration information. Thus, the third communication device can simultaneously wake up the first and second communication devices using the same paging configuration information, saving signaling overhead.

[0239] A possible implementation:

[0240] The transmission resource used by the third communication apparatus to send the paging information #A to the first communication apparatus is different from the transmission resource used by the third communication apparatus to send the paging information #A to the second communication apparatus.

[0241] For example, the third communication device can broadcast multiple paging configuration information, which are used to page the first communication device and the second communication device respectively, thereby supporting the first communication device and the second communication device to monitor paging information on different transmission resources. In this way, embodiments of the present application can support the first communication device and the second communication device to monitor paging information #A on different transmission resources.

[0242] In one possible implementation, the paging information #A may also include beam information for communication between the first communication device and the second communication device.

[0243] For example, the transmission beam and / or reception beam information of the first communication device may be configured in the paging information #A. For example, notification or indication may be performed through a synchronization signal and physical broadcast channel block (SSB), a precoding matrix indication (PMI), or other forms.

[0244] Exemplarily, the configuration of the transmitting beam information is described as an example. For example, SSB has 8 indexes, each index corresponds to a different beam, and the paging information #A may include a specific SSB index. The first communication device can determine the transmitting beam based on the specific SSB index included in the paging information #A.

[0245] In this way, the embodiment of the present application can quickly align the beam of the first communication device with the second communication device by indicating the beam information for communicating between the first communication device and the second communication device, thereby reducing the access delay.

[0246] It is understandable that the paging method 300 is also applicable to the scenario where the first communication device is the network device 130 and the second communication device is the terminal device 120. For a specific description, please refer to the above content and will not be repeated here.

[0247] It should be noted that when the first communication device is the network device 130 and the second communication device is the terminal device 120, the first communication device can determine that it is related to the first communication device through the first indication information in the paging message #A. Therefore, the first communication device can respond to the paging message #A. For example, the first communication device establishes inter-station interface transmission (e.g., Xn interface transmission) with the third communication device. For another example, the first communication device establishes an air interface connection with the second communication device.

[0248] The paging method 400 according to an embodiment of the present application will be described below in conjunction with FIG. 4 .

[0249] Figure 4 is an interactive flow chart of the paging method 400 of an embodiment of the present application. The method flow in Figure 4 can be executed by the first communication device / third communication device, or by a module and / or device (for example, a chip or integrated circuit, etc.) with corresponding functions installed in the first communication device / third communication device, and the embodiment of the present application is not limited. The following description will be made using the first communication device / third communication device as an example. The execution subjects of the paging method 400 are the first communication device and the third communication device. Among them, the first communication device can be the terminal device 120, and the third communication device can be the network device 110. As shown in Figure 4, the paging method 400 includes:

[0250] S410. The third communication device sends second indication information to the first communication device, for indicating at least one control resource set (core resource set, CORESET).

[0251] Correspondingly, the first communication device receives the second indication information from the third communication device, and determines at least one CORESET indicated by the third communication device according to the second indication information.

[0252] Specifically, each CORESET in the at least one CORESET can be used to indicate resources for the first communication device to receive DCI, that is, each CORESET is used to receive DCI.

[0253] Optionally, the DCI is encrypted using P-RNTI, and the embodiments of the present application are described using this as an example.

[0254] Optionally, the DCI may also be scrambled using other identifiers, which is not limited in the embodiments of the present application.

[0255] Specifically, the transmission resources for the first communication device to receive the DCI carried on the PDCCH are mainly determined by the CORESET and the search space (SS). Among them, the CORESET is used to indicate information such as the frequency domain resource information of the PDCCH and the number of OFDM symbols occupied by the time domain resources, and the search space is used to indicate the starting OFDM symbol of the PDCCH and the monitoring period, the associated CORESET and other information. The first communication device can determine the transmission resources for receiving the P-RNTI scrambled DCI through the CORESET and SS.

[0256] Generally, the third communication device may configure a search space identifier for indicating the SS used by the first communication device in the PDCCH common field of the system message. If the PDCCH common field does not configure a search space identifier, the first communication device may use a default Type 0-PDCCH resource, which may be a PDCCH resource for scheduling system information block 1 (SIB1).

[0257] For the SS associated with the paging, the third communication device usually configures its associated CORESET, and the first communication device detects the P-RNTI-scrambled DCI on this CORESET. If the third communication device does not configure the CORESET associated with the paging, the first communication device can detect the P-RNTI-scrambled DCI on CoreSet #0 (the default CORESET).

[0258] When the first communication device searches only for P-RNTI-scrambled DCI in the common search space (CSS) within the CORESET, the CSS within the CORESET is limited. If multiple first communication devices search for P-RNTI-scrambled DCI in the CSS, paging information about multiple first communication devices may not be sent in a timely manner. Therefore, the third communication device may send second indication information indicating at least one CORESET to the first communication device, and the first communication device may select an appropriate CORESET from among the second indication information.

[0259] S420: The first communication device determines CORESET#A in at least one CORESET according to the parameters of the first communication device.

[0260] Specifically, the parameters of the first communication device may include at least one of the following: a group identifier, a beam index, and a device identifier, etc. Each of the above-listed parameters is associated with the CORESET#A indicated by the third communication device.

[0261] In one possible implementation, the association between the parameters of the first communication device and CORESET#A is predefined by a protocol; or, the association between the parameters of the first communication device and CORESET#A is indicated. For example, the third communication device indicates the association between the parameters of the first communication device and CORESET#A to the first communication device.

[0262] Exemplarily, when the first communication device accesses the network, the third communication device indicates to the first communication device the association relationship between the parameters of the first communication device and CORESET#A.

[0263] By adopting the indication method, the embodiment of the present application can more flexibly indicate to the first communication device the association relationship between the parameters of the first communication device and the first control resource set. By adopting the protocol predefined method, the embodiment of the present application can reduce notification overhead.

[0264] Optionally, the association relationship between the parameters of the first communication device and CORESET#A may be indicated by the third communication device, or may be informed by the first communication device and the third communication device in a previous communication process.

[0265] The following will exemplarily describe the association relationship between the parameters of the first communication device and CORESET#A.

[0266] For example, the association relationship between the group identifier and the CORESET is as follows:

[0267] When the parameters of the first communication device include a group identifier, the third communication device (or the core network) may group multiple first communication devices into the same group and assign a group identifier to each group. For example, the group identifier of the first group may be #U, and the group identifier of the second group may be #Y. Each group may include multiple first communication devices.

[0268] The third communication device can be configured such that the first communication device corresponding to group ID #U corresponds to CORESET #1, and the first communication device corresponding to group ID #Y corresponds to CORESET #2. In this way, the first communication device determines the corresponding CORESET based on its own group ID, avoiding blind detection across multiple CORESETs simultaneously, thereby reducing the complexity of the first communication device.

[0269] For example, the association relationship between the group identifier and the CORESET can be seen in Table 2.

[0270] Table 2

[0271]

[0272] In Table 2, the first communication device with group identification #U selects CORESET#1; the first communication device with group identification #Y selects CORESET#2; the first communication device with group identification #P selects CORESET#3; and the first communication device with group identification #K selects CORESET#4.

[0273] Optionally, the third communication device may send the contents of Table 2 to the first communication device in the form of configuration information. In this way, the first communication device may determine the corresponding CORESET based on the second indication information sent by the third communication device and its own group identifier (when the contents shown in Table 2 are predefined by the protocol), thereby avoiding blind detection on multiple CORESETs at the same time, thereby reducing the complexity of the first communication device.

[0274] Optionally, the first communication device can also determine the corresponding CORESET based on the second indication information sent by the third communication device, the content shown in Table 2, and its own group identifier, to avoid blind detection on multiple CORESETs at the same time, thereby reducing the complexity of the first communication device.

[0275] In the above S410, the at least one CORESET indicated by the second indication information sent by the third communication device to the first communication device may be part or all of the CORSETs shown in Table 2, which is not limited in this embodiment of the present application.

[0276] It is understood that the above-mentioned grouping can be completed by the core network or by a third communication device. If completed by the core network, the core network will send the information of the first communication device and its corresponding group identifier information to the first communication device and the third communication device. If completed by the third communication device, the third communication device will indicate the group identifier corresponding to the first communication device to the first communication device. For example, through system information broadcast, or when the first communication device is in a connected state, through RRC signaling notification, etc.

[0277] Optionally, the contents shown in Table 2 may be configured in a manner predefined by the protocol.

[0278] For example, the association relationship between the device identifier and the CORESET #2 is:

[0279] When the parameters of the first communication device include a device identifier, the association between the device identifier of the first communication device and the CORESET can be predefined by the protocol or configured by the third communication device. For example, if the third communication device is configured with multiple CORESETs, the first communication device can determine the corresponding CORESET based on the device identifier of the first communication device.

[0280] By adopting the indication method, the embodiment of the present application can more flexibly indicate to the first communication device the association between the parameters of the first communication device and the first control resource set. By adopting the protocol predefined method, the embodiment of the present application can reduce the notification overhead.

[0281] Exemplarily, the third communication device numbers the configured multiple CORESETs, for example, from 0 to N-1, where N is the number of CORESETs configured by the third communication device, and the CORESET index to be detected by the first communication device = UE_ID mod N, where mod represents a modulo operation. In this way, the first communication device determines the corresponding CORESET based on its own device identifier, avoiding blind detection on multiple CORESETs simultaneously, thereby reducing the complexity of the first communication device.

[0282] For example, the association relationship between the device identifier and the CORESET can be seen in Table 3.

[0283] Table 3

[0284]

[0285] In Table 3, the first communication device with UE_ID mod N of 0 selects CORESET#0; the first communication device with UE_ID mod N of 1 selects CORESET#1; the first communication device with UE_ID mod N of 2 selects CORESET#2; and the first communication device with UE_ID mod N of N-1 selects CORESET#N-1.

[0286] Optionally, the third communication device may send the contents of Table 3 to the first communication device in the form of configuration information. In this way, the first communication device can determine the corresponding CORESET based on the second indication information sent by the third communication device and its own device identifier, avoiding blind detection on multiple CORESETs at the same time, thereby reducing the complexity of the first communication device.

[0287] Optionally, the contents shown in Table 3 may be configured in a protocol predefined manner.

[0288] In the above S410, the at least one CORESET indicated by the second indication information sent by the third communication device to the first communication device may be part or all of the CORSETs shown in Table 3, which is not limited in this embodiment of the present application.

[0289] For example, the association relationship between beam index and CORESET #3 is:

[0290] When the parameters of the first communication device include a beam index, the third communication device may configure an association between the beam index of the first communication device and a CORESET. For example, the third communication device may configure multiple CORESETs and indicate the association between the beam index of the first communication device and the multiple CORESETs.

[0291] For example, each beam index can be associated with a CORESET. For example, if there are four beam indices, beam index 0 is associated with CORESET 0, beam index 1 is associated with CORESET 1, beam index 2 is associated with CORESET 2, and beam index 3 is associated with CORESET 3. In this way, the first communication device can determine the corresponding CORESET under the corresponding beam index, avoiding blind detection on multiple CORESETs simultaneously, thereby reducing the complexity of the first communication device.

[0292] For example, the association relationship between the beam index and the CORESET can be seen in Table 4.

[0293] Table 4

[0294]

[0295] In Table 4, the first communication device with a beam index of 1 selects CORESET#1; the first communication device with a beam index of 2 selects CORESET#2; and the first communication device with a beam index of 3 selects CORESET#3.

[0296] Optionally, the third communication device may send the contents of Table 4 to the first communication device. In this way, the first communication device may determine the corresponding CORESET based on the second indication information sent by the third communication device and its own corresponding beam index, thereby avoiding blind detection on multiple CORESETs at the same time, thereby reducing the complexity of the first communication device.

[0297] Optionally, the contents shown in Table 4 may be configured in a protocol predefined manner.

[0298] In the above S410, the at least one CORESET indicated by the second indication information sent by the third communication device to the first communication device may be part or all of the CORSETs shown in Table 4, which is not limited in this embodiment of the present application.

[0299] When the parameters of the first communication device include a beam index, the first communication device can determine the corresponding CORESET through the synchronization signal block beam in which it is located. On the other hand, adjacent synchronization signal block beams can be associated with different control resource sets (such as different frequency domain positions), which can reduce interference.

[0300] In one possible implementation, one beam is used to transmit one SSB, i.e., one beam corresponds to one SSB. Therefore, the beam index and the SSB index may correspond one to one. The parameters of the first communication device may further include the SSB index.

[0301] For example, each SSB index can be associated with a CORESET. For example, there are four SSB indices, where SSB index 0 is associated with CORESET 0, SSB index 1 is associated with CORESET 1, SSB index 2 is associated with CORESET 2, and SSB index 3 is associated with CORESET 3. In this way, the first communication device can determine the corresponding CORESET under the corresponding SSB index, avoiding blind detection on multiple CORESETs at the same time, thereby reducing the complexity of the first communication device.

[0302] For example, the association relationship between the SSB index and the CORESET can be seen in Table 5.

[0303] Table 5

[0304]

[0305] In Table 5, the first communication device with an SSB index of 1 selects CORESET#1; the first communication device with an SSB index of 2 selects CORESET#2; and the first communication device with an SSB index of 3 selects CORESET#3.

[0306] Optionally, the third communication device may send the contents of Table 5 to the first communication device. In this way, the first communication device may determine the corresponding CORESET based on the second indication information sent by the third communication device and its own corresponding SSB index, thereby avoiding blind detection on multiple CORESETs at the same time, thereby reducing the complexity of the first communication device.

[0307] Optionally, the content shown in Table 5 may be configured in a protocol predefined manner.

[0308] In the above S410, the at least one CORESET indicated by the second indication information sent by the third communication device to the first communication device may be part or all of the CORSETs shown in Table 5, which is not limited in this embodiment of the present application.

[0309] For example, the association relationship between the SSB index (which may also be the beam index), the device identifier, and the CORESET is as follows:

[0310] When the parameters of the first communication device include an SSB index and a device identifier, the third communication device may configure an association relationship among the device identifier, the SSB index, and the CORESET of the first communication device.

[0311] Exemplarily, each SSB index is associated with multiple CORESETs. Since each SSB beam is associated with multiple CORESETs, the third communication device can determine the CORESET that the first communication device needs to detect based on the device identifier of the first communication device. For example, the third communication device can number the CORESETs associated with each SSB index from 0 to N-1, where N is the number of CORESETs associated with each SSB index, and the CORESET index that the first communication device needs to detect = UE ID mod N.

[0312] For example, there are four SSB indices, where SSB index 0 is associated with CORESET 0 and CORESET 1, SSB index 1 is associated with CORESET 2 and CORESET 3, SSB index 2 is associated with CORESET 0 and CORESET 1, and SSB index 3 is associated with CORESET 2 and CORESET 3. For the first communication device under SSB index 3, it determines that the beam is associated with CORESET 2 and CORESET 3 by obtaining the second indication information. The first communication device can first renumber CORESET 2 and CORESET 3 as CORESET 0 and CORESET 1, and then determine the corresponding CORESET according to the above formula: CORESET index = UE ID mod 2. For example, if the UE ID of the first communication device is 15, then the CORESET index = UE ID mod 2 = 1, and index 1 corresponds to CORESET 3. The first communication device then monitors the P-RNTI-scrambled DCI at CORESET 3.

[0313] In this way, the first communication device can determine the corresponding CORESET under the corresponding wave SSB index and device identification, avoiding blind detection on multiple CORESETs at the same time, thereby reducing the complexity of the first communication device.

[0314] For example, the association relationship between the status type and CORESET #5 is:

[0315] When the parameters of the first communication device include a status type, the third communication device may configure an association relationship between the status type of the first communication device and the CORESET.

[0316] For example, the third communication device may be configured with two CORESETs: one CORESET for the first communication device in an idle state and one CORESET for the first communication device in a third state (inactive). The third state may also be referred to as an inactive state. The first communication device can determine the appropriate CORESET based on its own state type, avoiding simultaneous blind detection on multiple CORESETs, thereby reducing the complexity of the first communication device.

[0317] For example, the association relationship between the status type and CORESET can be seen in Table 6.

[0318] Table 6

[0319]

[0320] In Table 6, the first communication device in the idle state selects CORESET#1; the first communication device in the third state selects CORESET#2.

[0321] Optionally, the third communication device may send the contents of Table 6 to the first communication device. In this way, the first communication device may determine the corresponding CORESET based on the second indication information sent by the third communication device and its own state type, thereby avoiding blind detection on multiple CORESETs at the same time, thereby reducing the complexity of the first communication device.

[0322] Optionally, the content shown in Table 6 can be configured in a protocol predefined manner.

[0323] In the above S410, the at least one CORESET indicated by the second indication information sent by the third communication device to the first communication device may be part or all of the CORSETs shown in Table 6, which is not limited in this embodiment of the present application.

[0324] By indicating multiple control resource sets for receiving downlink control information to the first communication device, the first communication device can select an appropriate control resource set according to the parameters, thereby avoiding blind detection on multiple CORESETs at the same time and reducing the complexity of the first communication device.

[0325] In other words, by configuring multiple CORESETs for monitoring DCI, the embodiment of the present application can solve the problem of insufficient control channel resources for monitoring DCI, thereby enhancing the paging capacity.

[0326] The first communication device can determine the corresponding CORESET under the corresponding parameters, avoiding blind detection on multiple CORESETs at the same time, thereby reducing the complexity of the first communication device. In addition, by configuring multiple CORESETs for monitoring DCI, the embodiment of the present application can improve frequency diversity gain.

[0327] It can be understood that the first communication device can determine an appropriate control resource set based on the above parameters, thereby reducing the complexity of the first communication device in determining the corresponding control resource set.

[0328] For example, when the parameters of the first communication device include a beam index, the first communication device can directly determine the corresponding control resource set based on the synchronization signal block beam index. Additionally, adjacent synchronization signal block beam indices can be associated with different control resource sets (e.g., different frequency domain locations), thereby reducing interference.

[0329] Optionally, the DCI may indicate, in addition to the transmission resources for receiving the paging information, at least one of the following:

[0330] System message changes, Earthquake and Tsunami Warning System (ETWS) information, Commercial Mobile Alert System (CMAS) messages, or notifications to stop paging detection, etc.

[0331] A possible implementation:

[0332] When the above-mentioned DCI indicates transmission resources for receiving paging information, the paging method 400 can be combined with the paging method 300 to form a new paging method. For details, please refer to the description in the summary of the invention.

[0333] For example, the paging method 300 shown in FIG3 relates to how to simultaneously wake up a first communication device and a second communication device. The paging method 400 shown in FIG4 relates to how to indicate to the first communication device a set of control resources for receiving DCI. Before executing the paging method 300, the third communication device may first execute the paging method 400. The first communication device may determine the set of control resources for receiving DCI based on the second indication information sent by the third communication device, and then determine the resources for receiving the aforementioned paging message #A based on the DCI.

[0334] The paging method 500 according to an embodiment of the present application will be described below in conjunction with FIG. 5 .

[0335] Figure 5 is an interactive flow chart of the paging method 500 of an embodiment of the present application. The method flow in Figure 5 can be executed by the first communication device / third communication device, or by a module and / or device (for example, a chip or integrated circuit, etc.) with corresponding functions installed in the first communication device / third communication device, and the embodiment of the present application is not limited. The following description will be given using the first communication device / third communication device as an example. The execution subjects of the paging method 500 are the first communication device and the third communication device. The first communication device can be the terminal device 120, and the third communication device can be the network device 110. As shown in Figure 5, the paging method 500 includes:

[0336] S510. The third communication device sends configuration information #A to the first communication device, for configuring transmission resource #A and at least one transmission resource #B.

[0337] Accordingly, the first communication device receives the configuration information #A from the third communication device.

[0338] Specifically, the first communication device receives downlink control information and paging information from different communication devices respectively according to the configuration information sent by the third communication device. In this way, the embodiment of the present application can enable the first communication device to receive paging information on a transmission resource different from the transmission resource used to receive downlink control information. In this way, the problem of insufficient physical downlink shared channel resources for sending paging information can be overcome.

[0339] Specifically, the first communication device can receive paging information based on the second transmission resource, and the downlink control information received based on the first transmission resource is used to indicate the reception of paging information. In this way, it can overcome the existing limitation that the resources used to receive paging information cannot exceed the size of control resource set #0, and then increase the transmission resources used to transmit paging information.

[0340] For example, transmission resource #A and transmission resource #B configured by configuration information #A are used to indicate PDCCH resources and PDSCH resources, respectively. The PDCCH resource is used by the first communications device to receive DCI, which indicates the reception of paging information #B. The PDSCH resource is used by the first communications device to receive paging information #B. For ease of description, this embodiment of the application uses the example where the PDCCH resource refers to transmission resource #A and the PDSCH resource refers to transmission resource #B.

[0341] In one possible implementation, the configuration information #A includes at least one of the following:

[0342] The cell identifier corresponding to the PDSCH resource, the starting position and size of the PDSCH resource, the resource number of the PDSCH resource or the carrier number of the PDSCH resource.

[0343] Specifically, the resource number of the PDSCH resource refers to the position or number of the PDSCH in the multiple PDSCH resources when the carrier on which the PDSCH used to receive the paging information #B is located includes multiple PDSCH resources. The carrier number of the PDSCH resource refers to the position or number of the carrier on which the PDSCH resource is located in the multiple carriers when the first communication device can receive the paging information #B on multiple carriers and each carrier supports one PDSCH resource.

[0344] The first communication device can determine the appropriate PDSCH resource based on the relevant information of the PDSCH resource indicated above, and receive paging information based on the PDSCH resource. In this way, it can overcome the existing limitation that the resources used to receive paging information cannot exceed the size of control resource set #0, and then increase the transmission resources used to transmit paging information.

[0345] PDCCH resource configuration can reuse existing mechanisms. For example, PDCCH resource configuration primarily includes core set configuration and search space configuration. Specifically, core set configuration indicates the frequency domain resources occupied by the core set, time domain symbols, whether interleaving is used, etc.; search space configuration indicates the period, time slot, offset, etc., used to determine the search time slot. All of these can continue to use existing mechanisms.

[0346] The first communication device may determine more detailed information about the second transmission resource based on the above information, so that the first communication device can receive paging information on the second transmission resource.

[0347] It is understandable that if the number of configurable PDSCH resources in a cell is large, the number of bits occupied by the resource number field for indicating the PDSCH resource in the new indication information sent by the third communication device to the first communication device can be determined based on the total number of PDSCH resources.

[0348] S520. The first communication device receives downlink control information from the third communication device and paging information #B from the second communication device according to the configuration information #A.

[0349] Specifically, the first communication device may receive DCI and paging information #B respectively according to the configuration information #A, wherein the DCI comes from the third communication device and the paging information #B comes from the second communication device.

[0350] The DCI received by the first communication device may be sent by the third communication device, and the paging information #B received by the first communication device may be sent by the second communication device. That is, the third communication device sends DCI to the first communication device to indicate that it is a paging indication, and the second communication device sends paging information #B to the first communication device. In this way, the embodiment of the present application can increase the capacity or number of PDSCH resources used to carry paging information.

[0351] Specifically, the first communication device receives DCI and paging information #B from different communication devices respectively according to the configuration information sent by the third communication device. In this way, the embodiment of the present application can enable the first communication device to receive paging information #B on a transmission resource different from the transmission resource used to receive DCI. In this way, the existing problem of insufficient PDSCH resources for sending paging information can be overcome.

[0352] Specifically, the first communication device can receive paging information #B based on the second transmission resource, and the DCI received based on the first transmission resource is used to indicate the reception of paging information #B. In this way, the existing limitation that the resources used to receive paging information cannot exceed the size of CORESET#0 can be overcome, and then the transmission resources used to transmit paging information can be increased.

[0353] In one possible implementation, the carrier corresponding to the PDCCH resource is different from the carrier corresponding to the PDSCH resource, so that cross-carrier scheduling of paging information can be supported.

[0354] In a possible implementation, the first communication device receives third indication information from the third communication device, which is used to indicate whether the quasi co-location (QCL) of the PDCCH resources is the same as the QCL of the PDSCH resources.

[0355] In this way, when the first communication device determines through the third indication information that the QCL of the PDCCH resource is different from the QCL of the PDSCH resource, it can be determined that the carrier corresponding to the PDCCH resource is different from the carrier corresponding to the PDSCH resource.

[0356] Specifically, the first communications device may determine whether to reuse the QCL information used to receive the DCI when receiving the paging information based on whether the QCLs of the first transmission resource and the second transmission resource indicated by the third indication information are the same. For example, if they are the same, the quasi-co-location information used to receive the downlink control information may be reused; if they are not the same, the quasi-co-location information used to receive the downlink control information is not reused.

[0357] Optionally, the first communication device may receive paging information #B and DCI from a third communication device, or may receive paging information #B from the third communication device and DCI from a second communication device. In the latter case, the first communication device may use different beams to receive paging information #B and DCI. The third communication device may define a field in the third indication information (e.g., the third indication information is DCI) to indicate whether the QCLs of the paging information #B and the DCI are the same.

[0358] Furthermore, the third communication device may also send fourth indication information to the first communication device to indicate beam information for communication between the first communication device and the second communication device. This beam information is used by the first communication device to receive paging information #B. See the following description for details.

[0359] In one possible implementation, the first communication device receives fourth indication information from the third communication device, which is used to indicate beam information for communication between the first communication device and the second communication device.

[0360] For example, the third communication device may indicate to the first communication device the beam information for communication between the first communication device and the second communication device through a DCI indication or a combination of a high-layer configuration and a DCI indication.

[0361] Specifically, the first communication device receives DCI and paging information #B from different communication devices. Therefore, the first communication device can determine the beam information used to receive the paging information #B through the above-mentioned fourth indication information, that is: the fourth indication information indicates what kind of beam the first communication device should use to receive the paging information #B, thereby avoiding the first communication device not receiving the paging information #B.

[0362] In one possible implementation, the first communications device determines whether the QCL of the PDCCH resource is the same as the QCL of the PDSCH resource by determining whether the carrier used to receive the DCI and the carrier used to receive the paging information #B are the same carrier. If they are the same carrier, the QCL of the PDCCH resource is the same as the QCL of the PDSCH resource; if they are not the same carrier, the QCL of the PDCCH resource is different from the QCL of the PDSCH resource.

[0363] In one possible implementation, the cell identifier for scrambling the PDCCH resources is different from the cell identifier for scrambling the PDSCH resources.

[0364] By using different cell identifiers to scramble different transmission resources, the embodiments of the present application can support the reuse of current implementation methods, thereby reducing the implementation complexity of cross-carrier scheduling scenarios for paging information.

[0365] In this way, the first communication device can determine whether the carrier corresponding to the PDCCH resource is the same as the carrier corresponding to the PDSCH resource based on the fact that the cell identifier used for the scrambled PDCCH resource is different from the cell identifier used for the scrambled PDSCH resource. In this way, cross-carrier scheduling of paging information can be supported.

[0366] It should be understood that the DCI and paging message #B received by the first communication device may originate from different communication devices. For example, the first communication device may receive DCI from a third communication device and paging message #B from a second communication device. Therefore, there may be a delay between the first communication device receiving the DCI and receiving the paging message #B.

[0367] Generally, factors that cause delay include at least one of the following:

[0368] The first communication device receives the arrival time difference of the downlink signals from the third communication device and the second communication device, the timing difference between the third communication device and the second communication device, the processing time of the first communication device switching the carrier, etc.

[0369] For example, assuming that the time of the last symbol of the PDCCH resource is n, the starting time of the PDSCH resource is no earlier than n+T, where T can be understood as the time delay between the two. The third communication device can indicate the time interval T between the PDCCH resource and the PDSCH resource through the third indication information or the fourth indication information.

[0370] Illustratively, the third indication information or the fourth indication information is used to indicate at least one of the following:

[0371] The number of time units between PDCCH resources and PDSCH resources; or the cyclic prefix (CP) length of PDSCH resources.

[0372] Optionally, the time unit may include at least one of the following:

[0373] Slot, mini-slot, non-slot, or symbol.

[0374] Specifically, the NR communication system supports the scheduling of mini-slots, which can start at any OFDM symbol in a time slot. Downlink mini-slots can be 2, 4, or 7 OFDM symbols, while uplink mini-slots can be any length between 1 and 14 OFDM symbols. Mini-slots can also be called non-slots.

[0375] For example, the third indication information or the fourth indication information includes a field #A, which is used to indicate the number of time slots between the PDCCH resources and the PDSCH resources.

[0376] For example, the third indication information or the fourth indication information includes a field #B, which is used to indicate the number of symbols spaced between the PDCCH resources and the PDSCH resources.

[0377] For example, the third indication information or the fourth indication information includes a field #C, which is used to indicate the CP length of the PDSCH resource.

[0378] The above-mentioned fields #A, #B, and #C can be combined with each other. For example, the third indication information or the fourth indication information indicates the number of time slot intervals and the number of symbol intervals between the PDCCH resources and the PDSCH resources through the combination of field #A and field #B; for example, the third indication information or the fourth indication information indicates the number of time slot intervals and the number of symbol intervals between the PDCCH resources and the PDSCH resources and the CP length of the PDSCH resources through the combination of field #A and field #C. For example, the third indication information or the fourth indication information indicates the number of time slot intervals and the number of symbol intervals between the PDCCH resources and the PDSCH resources and the CP length of the PDSCH resources through the combination of field #A, field #B, and field #C. For another example, the third indication information or the fourth indication information indicates the number of symbol intervals and the CP length of the PDSCH resources between the PDCCH resources and the PDSCH resources through the combination of field #B and field #C.

[0379] Exemplarily, when the third indication information or the fourth indication information is DCI, it may include two indications: slot indication + symbol indication, that is, there may be two fields, respectively used to indicate the number of slots and the number of symbols of the interval.

[0380] Optionally, the number of time slots of the interval between the PDCCH resources and the PDSCH resources may be indicated in a time domain resource allocation table for paging indication predefined in the protocol, and the number of time slots of the interval may be a non-negative integer.

[0381] Optionally, the DCI may also indicate the CP length of the PDSCH resource. For both intra-carrier and cross-carrier scheduling scenarios, the present invention supports different CP lengths, and may pre-define multiple different CP lengths by protocol, and indicate the CP length of the PDSCH resource via the DCI.

[0382] In this way, the embodiment of the present application can indicate the delay between the PDCCH resources and the PDSCH resources to the first communication device.

[0383] By indicating the time delay between the first transmission resource and the second transmission resource, the embodiment of the present application can enable the first communication device to receive the second transmission resource at an appropriate time, thereby avoiding the situation where the first communication device fails to receive the paging information in advance. In addition, this can also reduce the energy consumption of the first communication device.

[0384] It is understandable that the above-mentioned paging methods can be combined with each other to form a new technical solution. For example, the paging method 300 and the paging method 400 can be combined to form a new technical solution.
