[0040] By way of example, FIG. 1 is a schematic diagram of an architecture of a communication system provided in embodiments of the present application. As shown in FIG. 1, the communication system 100 can include a network device 110, which can be a device that communicates with a terminal device 120 (or a communication terminal, a terminal).

[0042] In embodiments of the present application, the communication system shown in FIG. 1 further includes a mobility management entity (MME), an access and mobility management function (AMF), and other network entities, which are not limited in embodiments of the present application.
[0043] It should be understood that the devices with communication functions in the network / system in the embodiments of the present application can be referred to as communication devices. For example, the communication system 100 shown in FIG. 1, the communication devices can include the network devices 110 and the terminal devices 120 with communication functions, and the network devices 110 and the terminal devices 120 can be the specific devices described above, which will not be described here again; the communication devices can also include other devices in the communication system 100, such as network controllers, mobile management entities, and other network entities, and the embodiments of the present application do not limit this.
[0044] For ease of understanding, some related technical knowledge related to the embodiments of the present application is introduced first. The following related technologies can be combined with the technical solutions of the embodiments of the present application in any way as an optional scheme, which all belong to the protection scope of the embodiments of the present application. The embodiments of the present application include at least part of the following contents.
[0045] With the development of mobile communication technology, a new generation of wireless evolution system (for example, a 5G system) improves the transmission rate of data through multiple technologies to meet the transmission demand of large data volume such as high-definition video and virtual reality. Multiple technologies such as multiple-input multiple-output (MIMO) technology, non-orthogonal multiple access technology, simultaneous same frequency full duplex communication technology, new modulation technology, new coding technology, and high-order modulation technology. Through these technologies, the peak rate can reach Gbit / s.
[0046] As an example, the delay level of the air interface needs to be around 1ms to meet the real-time application of automatic driving, remote medical treatment, etc. As an example, the super large network capacity can provide the connection ability of hundreds of billions of devices, thereby meeting the communication demand of the Internet of Things. As an example, the spectral efficiency of the NR system is more than 10 times higher than that of the LTE system. Based on continuous wide area coverage and high mobility, the user's experience rate can reach 100 Mbit / s. As can be seen, the traffic density and the connection number density are greatly improved.
[0047] In addition, the improvement of system coordination and intelligence further improves the flexibility of the network. System coordination can be manifested as the coordinated networking of multi-user, multi-point, multi-antenna, and multi-camera. Based on coordination and intelligence, the network can be automatically adjusted flexibly between networks.
[0048] However, in a communication system, the power consumption of a network device (e.g., a base station) is usually high. In order to save the power consumption of the network device, the system message needs to be optimized. For example, the network device usually periodically transmits SIB1 for initial access and schedules other SIBs for terminal devices in an idle / inactive mode. However, the network device always transmits even if there is no demand from the terminal device or no terminal device camping on the cell, which results in a large power consumption. For this reason, in order to save the network energy, the 3rd generation partnership project (3GPP) has carried out a lot of research on on-demand SIB1 for terminal devices in an idle / inactive mode in release 18 (R18) and R19 to achieve network energy saving by reducing unnecessary SIB1 transmission and associated physical random access channel (PRACH) monitoring.
[0049] In some communication systems, the NES function is introduced based on the demand for network energy saving. In a cell supporting the NES configuration, the network device can transmit SSB with a variable period and / or transmit SIB1 on demand. However, the terminal devices in the cell can support the NES function or not. Therefore, due to the emergence of the NES cell, the terminal devices can include legacy terminal devices and terminal devices supporting the NES configuration. The legacy terminal device can also be referred to as a legacy terminal device, and the terminal device supporting the NES configuration can also be referred to as an NES terminal device.
[0050] In a cell supporting the NES configuration, how to design the paging mechanism is a problem that needs to be further studied. When the network needs to connect with the terminal device, the network initiates a paging procedure to send a paging message to the terminal device. When the terminal device in an idle mode is in a sleep state in a discontinuous reception (DRX) cycle or an extended DRX (eDRX) cycle, it can periodically wake up to detect whether there is a paging message.
[0051] In some scenarios, when SIB1 in the cell is transmitted on demand, how to transmit the configurations or parameters related to paging in SIB1 needs to be considered. That is, how to change the paging mechanism to support the transmission of SIB1 on demand is a research direction. Further, in order to save energy better, how to adjust the related paging mechanism based on the existing technology is also a technical difficulty that needs to be studied.
[0052] In some scenarios, the legacy terminal device needs the network device to periodically send SIB, but the terminal device supporting NES configuration does not need to periodically send SIB. The paging mechanism needs to be flexibly configured based on different types of terminal devices in the cell. When the paging mechanism considers the detection requirements of both legacy terminal devices and NES terminal devices, it helps to save energy consumption. Therefore, how to improve the paging mechanism to be compatible with legacy terminal devices and NES terminal devices, so as to save the energy consumption of terminal devices, also becomes one of the research goals.
[0053] In some scenarios, how the cell supporting NES configuration sends the paging message to increase the sleep time of the cell also needs to be considered.
[0054] In summary, in the cell supporting NES configuration, how to design the paging mechanism to save energy consumption becomes a problem to be solved.
[0055] It should be noted that the above-mentioned problem that the paging mechanism needs to be compatible with two types of terminal devices due to the difference between the legacy terminal device and the NES terminal device is only an example. The embodiments of the present application can be applied to a communication scenario in which the paging mechanism needs to be compatible with any multiple types of terminal devices.
[0056] To solve the above problem, the embodiments of the present application provide a method for wireless communication. Through the method, the terminal device can determine one or more POs that need to be detected in the first period based on the first information. When the first information is related to the type of the terminal device, the PO or the PEI, different terminal devices can determine the PO corresponding to them. After the first information indicates that the PF is continuously set, the network device and the terminal device can perform centralized paging and detection in the continuous PF, thereby achieving effective energy saving. In order to facilitate understanding, the method proposed by the embodiments of the present application will be described in detail below in combination with FIG. 2. The method shown in FIG. 2 is executed by the terminal device.
[0057] Referring to FIG. 2, in step S210, the terminal device determines one or more POs corresponding to the terminal device in the first period according to the first information.
[0058] The terminal device can be in different states, which is not limited here. As an example, the terminal device can be in an idle state or an inactive state, and needs to detect whether there is a corresponding paging message in the first period. As an example, the terminal device can be in an active state or a radio resource control (RRC) connected state, and can determine the wake-up time and the PF / PO before entering the idle state, so as to timely receive the PEI or the paging message.
[0059] In some embodiments, the terminal device can be a communication device supporting NES configuration, or a communication device with NES function. That is, the terminal device can be the NES terminal device as described above.
[0060] In some embodiments, the terminal device can be a legacy terminal device, which can also be referred to as a legacy terminal device.
[0061] The service cell corresponding to the terminal device is a first cell. The terminal device can be connected to a network device of the first cell. In other words, the cell where the terminal device is located is the first cell, or the network device corresponding to the first cell can provide services for the terminal device.
[0062] In some embodiments, the first cell can be a cell where energy saving needs to be implemented on the network side. The cell can be any of the cells as described above. The energy saving that needs to be implemented on the network side can include energy saving of the network device, or energy saving of the core network. Alternatively, the first cell can be an NES cell, or a network energy saving cell with similar functions.
[0063] As an example, for a terminal device in an idle / inactive mode, the first cell that sends SIB1 on demand is an NES cell.
[0064] The network device can be any of the access network devices as described above, or a core network device. In some embodiments, the network device can be a communication device that sends a paging message to the terminal device. The terminal device can receive the paging message sent by the network device.
[0065] In some embodiments, when there is a paging message corresponding to a terminal device, the network device can determine the PO corresponding to the terminal device according to the identity (ID) of the terminal device, to send the paging message. For the terminal device, the terminal device also needs to determine one or more POs corresponding to the terminal device, and detect the paging message on the one or more POs, to reduce unnecessary energy consumption.
[0066] Exemplarily, a paging occasion (PO) is usually a set of monitoring opportunities of a physical downlink control channel (PDCCH), which is composed of multiple slots, and thus can also be referred to as a paging opportunity.
[0067] Exemplarily, one PO can contain S synchronization signal blocks (SSBs), where S can be determined by ssb-PositionsInBurst in the SIB1 message. The paging message sent on each SSB can be exactly the same.
[0068] As an example, the network device can send the paging message of the terminal device by broadcasting on the corresponding PO. The terminal device can detect on the corresponding PO to determine whether there is a paging message for itself.
[0069] As an example, after determining the one or more POs that need to be detected, the terminal device can detect the paging message on the one or more POs. In other words, the one or more POs are used for the terminal device to perform paging detection.
[0070] The one or more POs determined by the terminal device are the POs corresponding to the terminal device. When the terminal device has a paging message, the network device will send the paging message on the PO corresponding to the terminal device, so that the terminal device can receive it. Therefore, the one or more POs corresponding to the terminal device can also be replaced by the one or more POs that the terminal device needs to detect.
[0071] In some embodiments, the determination of the one or more POs by the terminal device means that the terminal device determines the time domain position and / or frequency domain position of the one or more POs. As an example, the frame in which the one or more POs are located can be referred to as PF. The time domain position of the one or more POs can be determined by the position parameter of the PF.
[0072] As an example, a PF can be composed of multiple POs. For example, there are Ns POs in one PF.
[0073] As an example, the position of the PO can be replaced by the position of the PF. The terminal device can determine the position of the PO after determining the position of the PF.
[0074] In some embodiments, the one or more POs corresponding to the terminal device can be located in one PF, or can be located in multiple PFs. The multiple PFs can be multiple PFs in one period, or multiple PFs located in multiple periods, which are not limited here.
[0075] As an example, the PF in which the one or more POs corresponding to the terminal device are located will also be used by the terminal device for paging detection. Therefore, the one or more POs corresponding to the terminal device can be replaced by the one or more PFs corresponding to the terminal device.
[0076] The terminal device needs to determine one or more POs corresponding to it in the first period. In some embodiments, the first period can be any one or more periods related to energy saving. If there is no PO to be detected in the first period, the terminal device can remain in a sleep state to save energy. For example, the first period can be one or more DRX periods of the terminal device. For another example, the first period can be one or more eDRX periods. In some embodiments, the first period can be one or more paging periods, so that the terminal device can periodically detect paging messages.
[0077] As an example, the first period can be one DRX period. After determining one or more POs corresponding to it in the DXR period, the terminal device can wake up before the PO to detect the paging message in the PO.
[0078] As an example, the first period can be multiple DRX periods. The terminal device can determine one or more POs corresponding to it in the multiple DRX periods, so as to better detect the paging message in the idle state or the inactive mode.
[0079] As an example, the first period can be one paging period. The paging period can be a default paging period configured by a higher layer, or a specific DRX period of the terminal device. For example, the paging period T = min (default paging period, UE specific DRX period).
[0080] As an example, the first period can be multiple default paging periods.
[0081] As an example, the first period can include one PF or a specified number of PFs.
[0082] As an example, the first period can be a specified time period. The time period can be a time period based on the NES function configuration or similar function configuration.
[0083] As an example, the first period can be any time period configured by a higher layer, which is not limited here.
[0084] In some embodiments, the position of one or more POs corresponding to the terminal device in the first period can be determined according to the configuration parameters of the first period and the ID (UE ID ) of the terminal device. For example, the position of the PO corresponding to any UE in the PF can be i s = floor (UE ID / N) mod N s .
[0085] As an example, for an NES terminal device, the position of the corresponding PO in the first period or any PF in the first period can be represented as is,NES .
[0086] As an example, the position of the PO in the first period can be represented as the position of the PO in the PF. The position can be represented by an index value.
[0087] As an example, the position i of the PO in the first period can be represented as the position of the PO in the PF. s,NES The starting position of a set of PDCCH monitoring opportunities can be indicated, and the terminal device can start receiving the paging message from the i s,NES th PO continuously.
[0088] The terminal device can determine one or more POs corresponding thereto in the first period according to the first information. In some embodiments, the terminal device can determine the first information in multiple ways. For example, the first information can come from the network device. For another example, the first information can be the information of the terminal device itself. For another example, the first information can be determined according to the PEI or other similar indication information received by the network device. For another example, the first information can be determined according to the higher-layer configuration information.
[0089] In some embodiments, the first information can be carried in one or more of the following information: SIB, RRC, downlink control information (DCI).
[0090] In some embodiments, the first information can include one or more of the following information: the type of PO in the first period; the type of terminal device; the type of PEI received by the terminal device / the type of PEI sent by the network device to the terminal device; and whether the PF in the first period is continuous. In other words, the terminal device can determine the corresponding one or more POs according to any one or a combination of any multiple of the information.
[0091] It should be noted that the terminal device can determine the corresponding one or more POs based on the combination of the first information and other arbitrary information, which is not limited.
[0092] The method for the terminal device to determine the corresponding PO according to the first information will be exemplarily described below in combination with multiple embodiments.
[0093] Embodiment 1
[0094] The first information can include the type of PO in the first period and / or the type of terminal device. The PO in the first period can include at least two types of POs. The at least two types of POs can be respectively used for sending at least two types of paging messages or performing paging behavior on at least two types of terminal devices. That is, the time-frequency resources (POs) used by the network side for sending paging messages can be divided into at least two groups.
[0095] In some embodiments, the at least two types of POs can include legacy POs, POs supporting NES configuration, and POs related to other power saving configurations, without limitation.
[0096] In some embodiments, the at least two types of POs can respectively correspond to at least two types of terminal devices, or respectively correspond to at least two types of application scenarios. A terminal device can perform paging detection on a PO corresponding to its type or application scenario. For brevity, the following takes an example of POs in a first cycle including two types of POs.
[0097] As an example, the POs in the first cycle can include first type POs and second type POs. The first type POs correspond to first type terminal devices without NES function, and the second type POs correspond to second type terminal devices with NES function. For example, the first type POs are used to send paging messages to legacy terminal devices, and the second type POs are used to send paging messages to NES terminal devices. That is, when a terminal device is a legacy terminal device, one or more POs corresponding to the terminal device are POs in the first type POs; when the terminal device has NES function, one or more POs corresponding to the terminal device are POs in the second type POs.
[0098] As an example, the first type POs are legacy POs, and the second type POs are NES POs. When a terminal device is a legacy terminal device, paging detection can be performed on the legacy POs. When the terminal device is an NES terminal device, paging detection can be performed on the NES POs.
[0099] In some embodiments, the positions of the first type POs and the second type POs in the first cycle can be determined respectively. For example, the positions of the first type POs can be determined based on a related calculation formula; the positions of the second type POs can be designated by the system through a network device or a higher layer.
[0100] As an example, the system can identify a specific system frame number (SFN) for a specific type of terminal device. For example, the system can identify a specific SFN for NES terminal devices, and continuously allocate a plurality of PFs for NES terminal devices or continuously allocate these PFs at some regular intervals.
[0101] As an example, the system can consider configuring / indicating the starting offset of each second type PO independently for each PF. For example, the system can indicate the starting offset of each NES PO for each PF.
[0102] In some embodiments, the positions of the second type of POs in the first cycle can be determined according to the positions of the first type of POs, in which case the paging behaviors of the different types of terminal devices do not affect each other. For example, when the first type of POs are legacy POs and the second type of POs are NES POs, the NES POs can be allocated based on the time / frequency offsets of the legacy POs.
[0103] As an example, any of the second type of POs can be determined according to the position of any of the first type of POs.
[0104] As an example, any of the second type of POs can be determined according to the positions of one or more of the first type of POs adjacent to the any of the second type of POs.
[0105] As an example, in a DRX cycle, the total number of POs provided by the system for NES terminal devices can be the same as the total number of POs for legacy terminal devices, to ensure that the paging delay levels of the legacy terminal devices and the NES terminal devices are the same.
[0106] As an example, in a DRX cycle, the total number of POs provided by the system for NES terminal devices can be different from the total number of POs for legacy terminal devices, to ensure the paging requirements of the different types of terminal devices.
[0107] As an example, NES POs can exist in each PF. For example, the NES POs can use the same paging frame as the legacy POs, and the index positions of the NES POs in each PF can be set according to the same rule.
[0108] As an example, the positions of the second type of POs in the first cycle are determined according to the positions of the first type of POs and a first offset value. Optionally, the first offset value can be configured by a network device or a higher layer.
[0109] As an implementation manner, the first offset value can be provided through a SIB or a DCI.
[0110] As an example, the ID determination manners of the first type of terminal devices and the second type of terminal devices are the same, to facilitate the allocation of the first type of POs and the second type of POs through offset values. The following takes the first type of POs as legacy POs and the second type of POs as NES POs as an example, to respectively describe the position determination manners of the first type of POs and the second type of POs.
[0111] The position i of the first type of POs in any PF in the first cycle s is: i s = floor(UE ID / N) mod N s ;
[0112] The position i of the second type of POs in any PF in the first cycles,NES For: i s,NES = PO offset + floor(UE ID / N) mod N s ;
[0113] Wherein, PO offset represents a first offset value, UE ID represents an ID of a terminal device, N represents a number of PFs in a period, N s represents a number of POs in a PF. The first offset value is an offset of PO for receiving a paging by the NES terminal device compared with a conventional terminal device.
[0114] Optionally, the UE ID may be determined according to an international mobile subscriber identity (IMSI) or a 5G S-temporary mobile subscription identifier (5G-S-TMSI).
[0115] As an example, the UE ID may be IMSI mod 1024.
[0116] As an example, if the terminal device is in an eDRX period, the UE ID may be 5G-S-TMSI mod 4096; otherwise, the UE ID may be 5G-S-TMSI mod 1024.
[0117] Optionally, any PF in a first period needs to satisfy a formula: (SFN + PF offset ) mod T = (T div N) * (UE ID mod N), wherein T represents a paging period, PF offset is a frame offset of PF.
[0118] As an example, after the terminal device calculates a PF in which the PO is located, the terminal device calculates a position i s,NES of the NES PO in the PF. The terminal device can perform paging detection according to the calculated position, and the same applies until a DCI corresponding to the terminal device is detected in the paging period. Through the above formula, the accurate positions of PF / PO corresponding to the conventional terminal device and the terminal device supporting the NES cell can be determined respectively, so that any terminal device can avoid detecting unnecessary multiple PF / PO.
[0119] For ease of understanding, a paging method coexisting with the traditional PO and NES PO is exemplarily described in combination with FIG. 3. FIG. 3 shows two DRX cycles. In the two DRX cycles, paging frames (PFs) occur periodically. In each PF, two traditional POs and one NES PO are included. As shown in FIG. 3, in each PF, after the traditional POs are determined, the NES PO can be determined according to the position and corresponding offset value of the PO adjacent thereto, or according to the position and corresponding offset value of the starting PO in the PF.
[0120] In some embodiments, the first type of PO and the second type of PO can be located in different PFs in the first cycle, respectively. That is, the system can indicate different PFs for different scenarios or different terminal devices to determine the corresponding POs. For example, the first type of PO is located in a first PF, and the second type of PO is located in a second PF.
[0121] As an example, the first PF and the second PF can be one or more PFs, respectively.
[0122] As an example, the first PF is a traditional PF, and the second PF is an NES PF. The POs located in the first PF can be used for traditional terminal devices, and the POs located in the second PF can be used for NES terminal devices. The traditional PFs are uniformly distributed in the DRX cycle, and the NES PFs can be different from the traditional PFs. In the NES cell, both traditional terminal devices and NES terminal devices can be supported. Since the NES terminal device can support different SSB cycles and on-demand SIBs, a separate PF and corresponding PO can be configured for the NES terminal device.
[0123] As an example, the system can set a PF dedicated to NES or a specific PF number for NES.
[0124] As an example, the system can indicate the PF for the first type of PO and the PF for the second type of PO through N NES One or more NES PFs are configured in a paging cycle. For example, since multiple PFs are uniformly distributed in the paging cycle, the simplest method is to configure only one PF in the paging cycle, that is, to enable N NES = 1. This can require changes to the RRC configuration to allow more values to be configured for nAndPagingFrameOffset, that is, to allow more intensive paging cycles.
[0125] As an implementation, N NES N can be extended from T / 16 to T / 32, T / 64, T / 128, T / 256. Then for a paging cycle T = 1280 ms, if N NES= T / 128, we will only have one NES PF in this cycle. Therefore, in order to adapt to the increase in the number of terminal devices that need to be paged in one PF, the number of subframes used for PO also needs to be increased, and the value range of Ns also needs to be increased.
[0126] As an example, the system can specify that the odd PF is the PF of the legacy terminal device (the first PF), and the even PF is the PF of the NES terminal device (the second PF). There are respective POs in the respective PFs. That is, any PO in the PF corresponding to the legacy terminal device belongs to the PO of the legacy terminal device, and any PO in the PF corresponding to the NES terminal device belongs to the PO of the NES terminal device.
[0127] As an example, the DCI can be configured separately for each NES PF and indicate the starting offset of the PO.
[0128] As an implementation, the first PF includes a first type of PO located at a first position, and the second PF includes a second type of PO located at a second position. The first position in the first PF is the same as the second position in the second PF, so as to facilitate the system to indicate.
[0129] As an implementation, the first PF includes a first type of PO located at a first position, and the second PF includes a second type of PO located at a second position. The first position in the first PF is different from the second position in the second PF, so as to distinguish different PFs.
[0130] As an example, the second PF can be determined according to the first PF and the second offset value. For example, the system can allocate the NES PF based on the time / frequency offset of the legacy PF. The legacy PF is uniformly distributed in the DRX cycle, so the NES PF will also be uniformly distributed in the DRX cycle, which does not affect the paging behavior of the legacy terminal device.
[0131] As an example, the first PF and the second PF can be in the same cycle or not.
[0132] As an example, the first cycle includes the first PF and the second PF. The second PF can be one or more PFs in the first cycle in addition to the first PF. For example, the legacy PF can coexist with the NES PF in the DRX cycle.
[0133] As an example, the second PF can be a PF in any period in the first set of periods. The first set of periods can be a set of multiple periods containing the second PF. The first information can be used to indicate whether the first set of periods includes the first period. That is, when different types of terminal devices correspond to different PFs respectively, the terminal device can determine whether the first period includes the second PF according to the first information. For example, for an NES terminal device, when the first information indicates that the first period includes an NES PF, the terminal device detects in the first period; and when the first information indicates that the first period does not include an NES PF, the terminal device does not detect in the first period.
[0134] As an implementation manner, when the first period is a DRX period, the system can specify information of the NES PF in each DRX period, and inform the terminal device through the first information. For example, the system can determine whether the first period includes the NES PF based on a current cell load and / or a number of NES terminal devices applying for access.
[0135] As an implementation manner, when the first period is a DRX period, the system can only configure the NES PF in a specified DRX period. That is, there is no NES PF in some DRX periods, and there is an NES PF in some DRX periods.
[0136] For ease of understanding, another paging manner in which the traditional PO and the NES PO coexist is exemplarily illustrated in combination with FIG. 4. FIG. 4 also shows two DRX periods. In the first DRX period, the traditional PF and the NES PF are included; and in the second DRX period, only the traditional PF is included. The PO in the traditional PF is a traditional PO, and the PO in the NES PF is an NES PO. As shown in FIG. 4, the position of the NES PO in the NES PF is the same as the position of the traditional PO in the traditional PF.
[0137] Embodiment 2
[0138] The first information can include the type of the terminal device. As known from the foregoing, the type of the terminal device is one of at least two types of terminal devices. For brevity, two types of terminal devices are exemplarily illustrated. The terminal devices that accept paging in the first period can be grouped based on different types. In other words, the type of the terminal device can be used to determine the first type of terminal device and the second type of terminal device.
[0139] In some embodiments, since the PO corresponding to the terminal device is determined according to the ID of the terminal device, different types of terminal devices can be grouped by ID. That is, the ID determination manner of different types of terminal devices is differentiated, so as to determine one or more POs corresponding to different types of terminal devices.
[0140] As an example, the ID determination manners of the first type of terminal device and the second type of terminal device can be different. Exemplarily, when the first type of terminal device is a legacy terminal device and the second type of terminal device is an NES terminal device, the network can differentiate the ID value of the legacy terminal device and the ID value of the NES terminal device in order to simultaneously support the legacy terminal device and the terminal device supporting the NES cell. For example, the value range of the ID of the legacy terminal device is different from the value range of the ID of the NES terminal device.
[0141] As an example, the index or number of the terminal device in the plurality of terminal devices is used to determine the PF in which the one or more POs are located. Since the ID determination manners of different types of terminal devices are different, the number values of the terminal devices after the plurality of types of terminal devices accepting paging are uniformly numbered can distinguish the different types of terminal devices and determine the PF corresponding to the terminal device.
[0142] As an example, all the POs in the first period are used to send paging messages for the first type of terminal device and the second type of terminal device. The PF in which the one or more POs corresponding to the terminal device are located is determined according to the paging density in the first period and the ID of the terminal device.
[0143] As an implementation manner, the paging density can be determined according to the number of the first type of terminal device and the second type of terminal device accepting paging in the first period.
[0144] As an implementation manner, the paging density can be determined according to the number of the first type of terminal device and the second type of terminal device in the first period.
[0145] As an example, the PF in which the one or more POs corresponding to the terminal device are located can be determined according to the number or index of the terminal device among all the terminal devices accepting paging in the first period.
[0146] As an example, the PF in which the one or more POs corresponding to the terminal device are located can be determined according to the paging density and the number or index of the terminal device among all the terminal devices accepting paging in the first period.
[0147] As an example, it is assumed that a group of users accepting paging in the first cell includes legacy terminal devices and NES terminal devices. The UEs id are legacy terminal devices, and the UEs NES_id are terminal devices supporting the NES cell. It is assumed that there are M1 UEs id accepting paging as legacy terminal devices, and there are M2 UEs NES_idNumber them uniformly, and the index index′ can be expressed as: index′ = 0, 1, 2, … M1 + M2 - 1.
[0148] Among them, the M1 + M2 terminal devices that receive paging can be numbered in sequence. After uniform numbering, the number of each terminal device can be determined according to the size relationship between M1 and M2. The number of terminal device i (i ∈ index′) can be determined according to the ID of terminal device i.
[0149] If M1 > M2, for the index range where index′ ≤ 2M2 - 1, the number of terminal device i can be:
[0150] For the index range where index′ ≥ 2M2, the number of terminal device i can be:
[0151] If M1 < M2, for the index range where index′ ≤ 2M1 - 1, the number of terminal device i can be:
[0152] For the index range where index′ ≥ 2M1, the number of terminal device i can be:
[0153] Let PF i correspond to the PF number of terminal device i among the M1 + M2 terminal devices; D f represents the paging density on PF, that is, the number of terminal devices allocated on each PF; D o can represent the number of terminal devices allocated on each PO.
[0154] PF i = i / D f , where
[0155] If then the paging of terminal device i is on the first paging frame; if the paging of terminal device i is on the second paging frame; if the paging of terminal device i is on the third paging frame; and so on, until the DCI of terminal device i is detected within the paging cycle. Through the above method, the accurate positions of the PFs corresponding to the traditional terminal devices and the terminal devices supporting the NES cell can be obtained respectively, thus avoiding detecting multiple unnecessary PFs.
[0156] Embodiment 3
[0157] The first information can include a type of the PEI received by the terminal device and / or a type of the terminal device. For the network device, the first information can include a type of the PEI sent to the terminal device and / or a type of the terminal device according to the first information.
[0158] It should be understood that the PEI in the embodiments of the present application can be replaced by an early paging indication (EPI).
[0159] In some embodiments, the PEI received by the terminal device can include at least two types of PEI. The at least two types of PEI can be used to indicate that at least two types of terminal devices receive the paging message respectively. That is, the PEI sent by the network side can be divided into at least two groups.
[0160] As an example, the at least two types of PEI can include a legacy PEI for a legacy terminal device and an NES PEI for an NES terminal device. For example, the PEI received by the terminal device can be a legacy PEI or an NES PEI.
[0161] As an example, when the network side sets the PEI, different types of PEI will be different in order to facilitate the terminal device to distinguish. Illustratively, the setting of the NES PEI can be different from the PEI of the legacy terminal device.
[0162] As an example, the network device can indicate different types of PEI through DCI or PEI occasion (PEI-O).
[0163] As an example, different types of PEI can have different identities, so as to determine the type of PEI according to the identity. The terminal device can determine the type of PEI according to the identity of the received PEI. The identity of the PEI can be carried in the PEI or sent before the PEI.
[0164] As an example, the type of PEI can be used by the terminal device to determine whether it needs to be woken up for paging detection.
[0165] In some embodiments, since the identification of the PEI can correspond to different types of terminal devices, the POs corresponding to different types of terminal devices can overlap, thereby saving resources. On the overlapping POs, different types of terminal devices can determine whether to be woken up based on the type of the received PEI. Exemplarily, when the PEI is a NES PEI, if the terminal device is a legacy terminal device, the PO / PF indicated by the PEI is not detected, and thus the terminal device does not need to be woken up; if the terminal device is a NES terminal device, the terminal device needs to be woken up to detect whether there is a paging message for the terminal device.
[0166] As an example, when the first type of terminal device corresponds to the first type of PO and the second type of terminal device corresponds to the second type of PO, the first type of PO and the second type of PO can all overlap or partially overlap.
[0167] As an example, if the legacy PO and the NES PO completely overlap, the ID determination manner of different types of terminal devices needs to be defined to be the same. That is, the terminal device ID allocated to the NES PO is the same as the terminal device ID allocated to the legacy PO.
[0168] As an example, when the first type of terminal device corresponds to the first type of PF and the second type of terminal device corresponds to the second type of PF, the first type of PF and the second type of PF can all overlap or partially overlap.
[0169] As an example, the NES PF / PO should overlap with the legacy PF / PO as much as possible. When the network device (for example, gNB) provides a paging message to a specific terminal device, the paging message can be sent through the overlapping POs of the legacy terminal device and the NES terminal device. Further, when the network device tries to wake up the NES terminal device, the identification of the PEI can prevent the legacy terminal device from being unnecessarily woken up.
[0170] In some embodiments, the type of the PEI sent by the network device to the terminal device can be determined based on the setting of the PEI. The NES PEI sent by the network device is different from the legacy PEI, so that when the NES terminal device needs to be woken up, the legacy terminal device will not be woken up.
[0171] Embodiment 4
[0172] The first information can include whether the PFs in the first period are continuous. If the PFs in the first period are continuous, the network device and the terminal device perform a paging behavior in the time period in which the PFs are continuous. If the PFs in the first period are uniformly distributed, the communication device performs a paging mechanism in a related manner.
[0173] In some embodiments, whether the PFs in the first period are continuous refers to whether the PFs in the first period are continuous in the time domain resource.
[0174] To save the energy of the network side, multiple PFs evenly distributed in a paging cycle can be configured as continuous or partially continuous PFs. In this scenario, the terminal device also only needs to perform paging detection in the continuous PFs, so the sleep time of the terminal device can also be increased.
[0175] In some embodiments, part or all of the PFs in the first cycle are continuous in the time domain resources. The one or more POs corresponding to the terminal device can be determined according to the time domain positions of the continuous part or all of the PFs in the first cycle.
[0176] Taking a default paging cycle of T = 128 radio frames as an example, when N = T / 16, there are only 8 paging frames every 1280 ms. If the calculation formula of the paging frame is (SFN + PF offset ) mod T = (T div N) x (UE ID mod N), the 8 paging frames are evenly distributed in the paging cycle. In this formula, due to the operation of (UE ID mod N), multiple terminal devices can be sequentially assigned to the 8 PFs according to UE ID In order to concentrate the PFs in a continuous time period, the calculation formula of the PF frame needs to be adjusted, and the PO calculation formula can remain unchanged.
[0177] As an example, when all the PFs in the first cycle are continuous in the time domain resources, all the PFs satisfy the following conditions: (SFN + PF offset ) mod T = UE ID mod N;
[0178] Wherein, SFN is the system frame number, PF offset represents the offset value of all PFs in the first cycle, and T represents the paging cycle.
[0179] If PF offset = 0, the continuous multiple PFs are located at the starting position of the first cycle. FIG. 5 is a schematic diagram of PF offset = 0. Wherein, T = 128 radio frames, and N = T / 16. As shown in FIG. 5, the PF frames are concentrated in the first 8 radio frames of the cycle T, and the frames thereafter do not need to be paged.
[0180] The above describes the method for determining the one or more POs corresponding to the terminal device on the terminal device side. The one or more POs are used for the network device side to send a paging message to the terminal device, so the network device side also needs to determine the one or more POs. The method for the network device to determine the one or more POs is described below in conjunction with FIG. 6. For the sake of brevity, the terms already explained in FIG. 2 will not be repeated.
[0181] Referring to FIG. 6, at step S610, the network device determines one or more POs corresponding to the terminal device in a first period according to first information. The network device is any network device or core network device corresponding to a first cell in which the terminal device is located, which will not be described herein again.
