[Means for solving the problem]

[0004] According to a first aspect, a paging method is provided, the paging method including a step in which a terminal device determines at least one paging bandwidth for carrying a paging message of the terminal device, each of the at least one paging bandwidth being equal to or less than a bandwidth of a minimum bandwidth capability of the terminal device, and a step in which the terminal device receives the paging message in the at least one paging bandwidth.

[0038] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the technical solutions in the embodiments of the present disclosure will be described clearly and completely with reference to the drawings in the embodiments of the present disclosure.

[0039] It is understood that the technical solutions of the embodiments of the present disclosure can be applied to various communication systems, such as a Global System of Mobile communication (GSM) system, a Code Division Multiple Access (CDMA) system, a Wideband Code Division Multiple Access (WCDMA) system, a General Packet Radio Service (GPRS), a Long Term Evolved (LTE) system, an LTE Frequency Division Duplex (FDD) system, an LTE Time Division Duplex (TDD), a Universal Mobile Telecommunication System (UMTS), a Worldwide Interoperability for Microwave Access (WiMAX) communication system, a New Radio (NR) or a future 5G system.

[0040] In particular, the technical solution of the embodiment of the present disclosure can be applied to various communication systems based on non-orthogonal multiple access technology, such as a Sparse Code Multiple Access (SCMA) system and a Low Density Signature (LDS) system, and of course the SCMA system and the LDS system are also called by other names in the communication field. Furthermore, the technical solution of the embodiment of the present disclosure can be applied to a multi-carrier transmission system adopting a non-orthogonal multiple access technology, such as an Orthogonal Frequency Division Multiplexing (OFDM), Filter Bank Multi-Carrier (FBMC), Generalized Frequency Division Multiplexing (GFDM), Filtered-OFDM (F-OFDM) system adopting a non-orthogonal multiple access technology.

[0041] The terminal device in the embodiments of the present disclosure may be a User Equipment (UE), an access terminal, a user unit, a subscriber station, a mobile station, a mobile station, a remote station, a remote terminal, a mobile device, a user terminal, a terminal, a wireless communication device, a user agent, or a user device. The access terminal may be a mobile phone, a wireless telephone, a Session Initiation Protocol (SIP) telephone, a Wireless Local Loop (WLL) station, a Personal Digital Assistant (PDA), a handheld device with wireless communication capabilities, a computing device or other processing device connected to a wireless modem, an in-vehicle device, a wearable device, a terminal device in a future 5G network, or a terminal device in a future evolved Public Land Mobile Network (PLMN), etc., but the embodiments of the present disclosure are not limited thereto.

[0042] The network device in the embodiments of the present disclosure may be a device for communicating with a terminal device, and the network device may be a base station (Base Transceiver Station, BTS) in GSM or CDMA, a base station (NodeB, NB) in a WCDMA system, an evolved base station (Evolutional NodeB, eNB or eNodeB) in an LTE system, a radio controller in a Cloud Radio Access Network (Cloud Radio Access Network, CRAN) scene, or the network device may be a relay station, an access point, an in-vehicle device, a wearable device, a network device in a future 5G network or a network device in a future evolved PLMN network, etc., but the embodiments of the present disclosure are not limited thereto.

[0043] FIG. 1 is a schematic diagram of one application scene of an embodiment of the present disclosure. The communication system in FIG. 1 may include a terminal device 10 and a network device 20. The network device 20 is for providing communication services to the terminal device 10 and accessing a core network, and the terminal device 10 accesses the network by searching for a synchronization signal, a broadcast signal, etc. transmitted from the network device 20, thereby communicating with the network. The arrows shown in FIG. 1 may represent uplink / downlink transmissions over a cellular link between the terminal device 10 and the network device 20.

[0044] In a 3rd Generation Partnership Project (3GPP) LTE system, a network can send a paging to a UE in an idle state. The paging process may be triggered by a core network or a base station to send a paging request to a UE in an idle state, or to notify the system of an information update, or to notify the UE to receive information such as Earthquake and Tsunami Warning System (ETWS) and Commercial Mobile Alert Service (CMAS). When a base station receives a paging message from a core network, it decodes the content therein, obtains a Tracking Area Identity (TAI) list for the UE, and performs air interface paging in cells belonging to the tracking areas in the list.

[0045] Within the system bandwidth, there exists a paging bandwidth for carrying paging messages, and the paging bandwidth in the prior art is likely to be larger than the bandwidth capability of the paged terminal device, thereby preventing the paged terminal device from receiving its own paging message.

[0046] In this case, the embodiment of the present disclosure provides a paging method that can avoid the occurrence of the above problem.

[0047] It is understood that the terms "system" and "network" are often used interchangeably herein. The term "and / or" in this specification only describes the relation between related objects and indicates that there are three relations, for example, A and / or B indicates that A exists alone, A and B exist simultaneously, and B exists alone. In addition, the symbol " / " in this specification generally indicates that the related objects before and after it are in an "or" relation.

[0048] 2 is a schematic block diagram of a paging method 100 according to an embodiment of the present disclosure. As shown in FIG. 2, the method 100 includes the following parts or wholes: At S110, the terminal device determines at least one paging bandwidth for carrying a paging message of the terminal device, each of the at least one paging bandwidth being less than or equal to a bandwidth of a minimum bandwidth capability of the terminal device. At S120, the terminal device receives the paging message on the at least one paging bandwidth.

[0049] The network device can arrange multiple paging bandwidths in the system bandwidth, and each paging bandwidth can be equal to or smaller than the bandwidth of the minimum bandwidth capability of the terminal device, for example, 10 MHz. This can avoid the occurrence of some terminal devices being unable to receive the paging message because the bandwidth capability of the own device is smaller than the paging bandwidth. The network device can arrange one paging bandwidth for each terminal device, or arrange multiple paging bandwidths for each terminal device, in order to reduce congestion of paging message transmission. The network device can arrange the paging bandwidth periodically, which can further improve flexibility. For example, the network device can predetermine the bandwidth capability of all terminal devices in the cell covered by the network device at a certain time, and arrange the paging bandwidths in the system bandwidth according to the minimum bandwidth capability, such that none of the paging bandwidths is larger than the bandwidth of the minimum bandwidth capability, in order to enable all terminal devices in the cell covered by the network device to receive the paging message. The network device can transmit the paging message to the terminal device in at least one paging bandwidth, and the terminal device can first determine the paging bandwidth belonging to itself, and then receive its paging message in the paging bandwidth belonging to itself.

[0050] Therefore, the paging method of the embodiment of the present disclosure can avoid the problem of the terminal device being unable to receive paging messages due to insufficient bandwidth capability by taking into account the bandwidth of the minimum bandwidth capability of the terminal device when allocating paging bandwidth.

[0051] First, the paging bandwidth is defined to carry paging messages, but does not exclude carrying other information such as synchronization information in the paging bandwidth. The paging bandwidth in the embodiment of the present disclosure is defined in the frequency domain, and different paging bandwidths may not overlap at all in the frequency domain, or may overlap partially, and are not limited in the time domain, that is, the paging bandwidths may completely overlap in the time domain. For example, the system bandwidth is 40 MHz, and the highest and lowest resources of 10 MHz and 10 MHz on the same symbol can be two paging bandwidths.

[0052] In an embodiment of the present disclosure, the method further includes a step of determining a plurality of paging bandwidths for the terminal device to carry a paging message, each of the plurality of paging bandwidths being equal to or less than the bandwidth of the minimum bandwidth capability, and the determination of at least one paging bandwidth for the terminal device to carry the paging message of the terminal device includes the terminal device determining the at least one paging bandwidth from among the plurality of paging bandwidths.

[0053] The terminal device may determine a plurality of paging bandwidths arranged by the network device in the system bandwidth, and further, the terminal device may determine at least one paging bandwidth belonging to itself from among the plurality of paging bandwidths. For example, the terminal device predetermines an identifier of at least one paging bandwidth belonging to itself, and when the terminal device knows the frequency domain locations of the plurality of paging bandwidths in advance, the terminal device may know the frequency domain location of the at least one paging bandwidth belonging to itself. It is understood that the plurality of paging bandwidths in the system bandwidth may be pre-arranged by the network device, or may be agreed upon by a protocol that may be pre-set in the terminal device, for example. Meanwhile, the terminal device may obtain at least one paging bandwidth belonging to itself without combining all paging bandwidths in the system bandwidth. For example, the obtained paging indication information directly indicates the at least one paging bandwidth, and in this case, the terminal device may directly determine at least one paging bandwidth belonging to itself according to the paging indication information.

[0054] In NR, wideband carriers up to 400 MHz are supported. On the network side, there is no problem in supporting wideband carriers, but for UEs, it is limited by cost, power, etc., and the maximum supported bandwidth is limited by the UE's capabilities. Therefore, for one wideband carrier, one or more bandwidth parts (BWPs) are configured, and each BWP may include a set of consecutive PRBs. For one UE, a maximum of one active downlink (DL) BWP and a maximum of one active uplink (UL) BWP are allowed to exist simultaneously in one serving cell. Furthermore, before a BWP is configured for a UE, there is an initial active DL / UL BWP, and an active DL / UL BWP can be configured for the UE during or after the Radio Resource Control (RRC) connection establishment process.

[0055] By distributing multiple paging bandwidths defined within the system bandwidth across multiple different BWPs, the paging load can be averaged across the different BWPs, and some paging bandwidths among the multiple paging bandwidths may also be in the same BWP, for example, the multiple paging bandwidths may partially overlap or not overlap at all in the same BWP intermediate frequency region.

[0056] In an embodiment of the present disclosure, the method further includes a step in which the terminal device receives configuration information of the multiple paging bandwidths transmitted from the network device, and the terminal device determining the at least one paging bandwidth from among the multiple paging bandwidths includes the terminal device determining a frequency domain location of each of the at least one paging bandwidth based on an identifier of the terminal device and the configuration information of the multiple paging bandwidths.

[0057] The terminal device can determine a frequency domain location where at least one paging bandwidth belonging to itself is located based on its own identity (ID). For example, UE_ID=(International Mobile Subscriber Identification Number (IMSI) mod 1024), paging bandwidth index=UE_ID mod N, where N is the number of all paging bandwidths in the system bandwidth. The network device can indicate the location information of multiple paging bandwidths in the system bandwidth to the terminal device, so that the terminal device can know the frequency domain locations where all paging bandwidths are located, and further, the terminal device can determine the frequency domain locations where the paging bandwidths belonging to itself are located based on the determined indexes of the paging bandwidths belonging to itself.

[0058] In an embodiment of the present disclosure, the configuration information of the multiple paging bandwidths includes frequency domain location information of each of the multiple paging bandwidths and / or frequency domain offset information of each of the multiple paging bandwidths.

[0059] The network device may directly indicate the frequency domain location of each of the multiple paging bandwidths to the terminal device, or may indirectly indicate the location by a frequency domain offset or the like. For example, the network device may indicate the paging bandwidth offset relative to the frequency domain location of a synchronization signal block (SSB), or the paging bandwidth offset relative to the frequency domain location of a broadcast signal. The network device may indicate the paging bandwidth offset relative to the frequency domain location of a center frequency point of the system bandwidth, or may indicate the paging bandwidth offset by the frequency domain location of a certain BWP. For example, the network device may notify the terminal device of the arrangement information of each BWP in advance, and the number of paging bandwidths is the same as the number of BWPs arranged by the network, that is, the network device may notify the terminal device that one paging bandwidth is arranged in each BWP, so that the terminal device may know in advance that each paging bandwidth occupies the central 10 MHz of the BWP in which it is located. When the terminal device knows the arrangement information of each BWP, it can know the frequency domain location occupied by each paging bandwidth.

[0060] In an embodiment of the present disclosure, the configuration information of the multiple paging bandwidths is carried in the remaining minimum system information RMSI.

[0061] When the paging bandwidth is allocated by the network device, the network device may inform the terminal device of the allocation information of the paging bandwidths through a system message, for example, the system message may be either Remaining minimum system information (RMSI) or other system information (OSI).

[0062] In an embodiment of the present disclosure, the multiple paging bandwidths belong to multiple paging bandwidth sets that correspond one-to-one to multiple sets of paging parameters for determining paging frames and / or paging occasions.

[0063] After the terminal device obtains the paging bandwidth belonging to itself, the terminal device needs to know the paging parameters belonging to itself, for example, the terminal device needs to know the paging occasion (PO) belonging to itself, so that the terminal device can receive the paging message at the corresponding time. Those skilled in the art will understand that after the base station receives the paging message of the core network, the paging messages of the UEs with the same PO can be aggregated into one paging message and sent to the related UEs via the paging channel. The UE receives the paging parameters in the system message, calculates the PO together with its IMSI, and receives the paging message at the corresponding time. The paging message is carried by the Physical Downlink Shared Channel (PDSCH), and the UE obtains the paging indication information by detecting the Physical Downlink Control Channel (PDCCH) scrambled by the Paging-Radio Network Temporary Identity (P-RNTI), thereby receiving the paging message. A UE in Idle state saves power with Discontinuous Reception (DRX), and the UE obtains DRX-related information from system messages. A PO on a paging frame (PF) during one DRX cycle listens to the PDCCH scrambled by the P-RNTI to receive a paging message. The PF indicates in which system frame number the paging message should appear, and the PO indicates the subframe time in which it may appear.

[0064] Paging parameters may be configured independently for different paging bandwidths, and multiple paging bandwidths may be divided into multiple paging bandwidth sets, and a set of paging parameters may be configured independently for paging bandwidths within each paging bandwidth set; that is, paging parameters corresponding to different paging bandwidth sets may be configured independently, but paging parameters for paging bandwidths in the same paging bandwidth set are commonly configured.

[0065] The number of paging bandwidths in each paging bandwidth set may be the same or different, for example, a first paging bandwidth set includes one paging bandwidth, and a second paging bandwidth set includes two paging bandwidths. Paging bandwidths belonging to the same BWP may be divided into the same paging bandwidth set.

[0066] The paging parameters may be independently configured for different paging bandwidths or different bandwidth sets, allowing the network devices some flexibility in sending paging messages.

[0067] The network device may transmit paging messages to the terminal device via different beams for different paging bandwidths, and the different beams can be time-division transmitted via time-division multiplexing (TDM), thereby improving resource utilization.

[0068] In an embodiment of the present disclosure, the paging parameters are carried in the remaining minimum system information RMSI or other system information OSI.

[0069] As can be seen from the above description, the network device may inform the paging parameter of the paging bandwidth through a system message, for example, the system message may be either RMSI or OSI.

[0070] 3 is a schematic block diagram illustrating a paging method 200 according to an embodiment of the present disclosure. As shown in FIG. 3, the method 200 includes the following parts or wholes: In S210, the network device determines the terminal device to be paged. At S220, the network device transmits a paging message to the terminal device on at least one paging bandwidth, each of the at least one paging bandwidth being less than or equal to a bandwidth of a minimum bandwidth capability of the terminal device.

[0071] Therefore, the paging method of the embodiment of the present disclosure can avoid the problem of the terminal device being unable to receive paging messages due to insufficient bandwidth capability by taking into account the bandwidth of the minimum bandwidth capability of the terminal device when allocating paging bandwidth.

[0072] In an embodiment of the present disclosure, the method further includes a step in which the network device transmits to the terminal device configuration information of a plurality of paging bandwidths for carrying paging messages, the configuration information of the plurality of paging bandwidths being used by the terminal device to determine a frequency domain location of the at least one paging bandwidth, each of the plurality of paging bandwidths being equal to or less than the bandwidth of the minimum bandwidth capability.

[0073] In an embodiment of the present disclosure, the configuration information of the multiple paging bandwidths includes frequency domain location information of each of the multiple paging bandwidths and / or frequency domain offset information of each of the multiple paging bandwidths.

[0074] In an embodiment of the present disclosure, the configuration information of the multiple paging bandwidths is carried in the remaining minimum system information RMSI.

[0075] In an embodiment of the present disclosure, the frequency domain locations of at least two of the multiple paging bandwidths do not completely overlap.

[0076] In an embodiment of the present disclosure, the multiple paging bandwidths belong to multiple paging bandwidth sets that correspond one-to-one to multiple sets of paging parameters for determining paging frames and / or paging occasions.

[0077] In the embodiment of the present disclosure, paging bandwidths of the same paging bandwidth set belong to the same bandwidth portion BWP.

[0078] In an embodiment of the present disclosure, the paging parameters are carried in the remaining minimum system information RMSI or other system information OSI.

[0079] It should be understood that the interactions between the network device and the terminal device and related characteristics, functions, etc. described by the network device correspond to the related characteristics, functions of the terminal device, and the related contents are described in detail in the above method 100, and therefore will not be described here for brevity.

[0080] Furthermore, in each embodiment of the present disclosure, it should be understood that the numbers of each of the above processes do not indicate the order of execution, but rather the order of execution of each process is determined by its function and internal logic, and does not in any way limit the implementation process of the embodiments of the present disclosure.

[0081] The paging method according to an embodiment of the present disclosure has been described in detail above. Below, a paging device according to an embodiment of the present disclosure will be described with reference to Figures 4 to 7, and the technical features described in the method embodiment are applied to the following device embodiments.

[0083] Therefore, a terminal device of an embodiment of the present disclosure can avoid a problem in which the terminal device is unable to receive paging messages due to insufficient bandwidth capability by taking into account the bandwidth of the terminal device's minimum bandwidth capability when allocating paging bandwidth.
