Transmitting method, receiving method, device, equipment and storage medium

[0001] This disclosure claims priority to the Chinese patent application filed with the China Patent Office on November 29, 2023, with application number 202311619951.2 and application name “Sending method, receiving method, device, equipment and storage medium”, the entire content of which is incorporated by reference in this disclosure. Technical Field

[0002] The present disclosure relates to the field of communication technologies, and in particular to a sending method, a receiving method, an apparatus, a device, and a storage medium. Background Art

[0003] In mobile communications, the status of a terminal can be divided into idle state, connected state and inactive state. In the inactive state, the terminal maintains a connection with the core network, but has no connection with the access network. When the terminal enters the inactive state, the access network configures a Radio Access Network based Notification Area (RNA) for the terminal, which includes one or more cells. After the terminal enters the inactive state, if the cell to which the terminal belongs receives downlink service data or signaling data for the terminal from the core network, the cell notifies the terminal through a paging message in the cell. If the RNA contains multiple cells, the cell sends a message to other cells in the RNA to request other cells to page the terminal synchronously. When the terminal leaves the RNA, the terminal can initiate a Radio Access Network Notification Area Update (RAN-based Notification Area Update, RNA Update) process to report the latest cell to which the terminal belongs to the access network.

[0004] Summary of the Invention

[0005] The present disclosure aims to solve, at least to a certain extent, one of the technical problems in the related art, namely, that the access network equipment consumes a large amount of transmission power and wastes PDSCH time-frequency resources.

[0030] The following describes in detail embodiments of the present disclosure, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended only to explain the present disclosure and are not to be construed as limiting the present disclosure. On the contrary, the embodiments of the present disclosure include all variations, modifications, and equivalents that fall within the spirit and scope of the appended claims.

[0031] In order to better understand a sending method disclosed in an embodiment of the present disclosure, the communication system to which the embodiment of the present disclosure is applicable is first described below.

[0032] Please refer to Figure 1, which is a schematic diagram of the architecture of a communication system provided in an embodiment of the present disclosure. The communication system may include, but is not limited to, an access network device and a terminal. The number and configuration of devices shown in Figure 1 are for example purposes only and do not limit the embodiments of the present disclosure. In actual applications, two or more access network devices and two or more terminals may be included. The communication system shown in Figure 1 includes, for example, an access network device 101 and a terminal 102.

[0033] It should be noted that the technical solutions of the embodiments of the present disclosure can be applied to various communication systems, such as long-term evolution (LTE) systems, fifth-generation (5G) mobile communication systems, 5G new radio (NR) systems, or other future new mobile communication systems.

[0034] The access network device 101 in the embodiments of the present disclosure is an entity on the network side for transmitting or receiving signals. For example, the access network device 101 can be an evolved NodeB (eNB), a transmission reception point (TRP), a next generation NodeB (gNB) in an NR system, a base station in other future mobile communication systems, or an access node in a wireless fidelity (WiFi) system. The embodiments of the present disclosure do not limit the specific technology and specific device form adopted by the access network device.

[0035] The access network device provided by the embodiment of the present disclosure may be composed of a centralized unit (CU) and a distributed unit (DU), wherein the CU may also be called a control unit. The CU-DU structure may be used to split the protocol layer of the access network device, such as a base station, with some functions of the protocol layer being centrally controlled by the CU, and the remaining part or all of the functions of the protocol layer being distributed in the DU, which is centrally controlled by the CU.

[0036] The terminal 102 in the embodiment of the present disclosure is an entity on the user side for receiving or transmitting signals, such as a mobile phone. The terminal may also be referred to as a terminal, user equipment (UE), mobile station (MS), mobile terminal (MT), etc. The terminal may be a car with communication capabilities, a smart car, a mobile phone, a wearable device, a tablet computer (Pad), a computer with wireless transceiver capabilities, a virtual reality (VR) terminal, an augmented reality (AR) terminal, a wireless terminal in industrial control, a wireless terminal in self-driving, a wireless terminal in remote medical surgery, a wireless terminal in a smart grid, a wireless terminal in transportation safety, a wireless terminal in a smart city, a wireless terminal in a smart home, etc.

[0037] The embodiments of the present disclosure do not limit the specific technology and specific device form adopted by the terminal.

[0038] It can be understood that the communication system described in the embodiment of the present disclosure is for the purpose of more clearly illustrating the technical solution of the embodiment of the present disclosure, and does not constitute a limitation on the technical solution provided by the embodiment of the present disclosure. Ordinary technicians in this field can know that with the evolution of the system architecture and the emergence of new business scenarios, the technical solution provided by the embodiment of the present disclosure is also applicable to similar technical problems.

[0039] In the related art, an inactive terminal monitors the paging occasion (PO) of the access network in each discontinuous reception (DRX) cycle in order to obtain service establishment requirements or cell message update indications in a timely manner. The paging occasion is a collection of physical downlink control channel (PDCCH) monitoring occasions, which is used to carry paging downlink control indications (DCI). The paging frame (PF) contains one or more POs, or the starting position of the PO. The paging DCI is used to schedule the PDSCH that carries the paging message and / or indicates the paging short message. Each PO contains a group of S consecutive paging DCI monitoring occasions, where S is the number of synchronization signals and physical broadcast channel blocks (SSB) actually sent in the cell. The kth listening opportunity in the PO corresponds to the kth SSB actually sent. Therefore, different listening opportunities in the PO correspond to different beam directions, so that paging scheduling information and / or paging short message indications are sent at all listening opportunities in a PO, completing the beam scanning of a paging process. The terminal can assume that the paging messages sent at all listening opportunities in a PO are the same.

[0040] However, in some application scenarios, the number of SSBs actually sent by the cell is large. For example, in the terrestrial millimeter wave scenario, the maximum number of SSBs that can be sent is 64. In the non-terrestrial network (NTN) scenario, the number of SSBs is even larger. Therefore, the paging DCI monitoring opportunities contained in each PO also increase accordingly. When the terminal is in an inactive state, the access network device can only know the RNA where the terminal is located, but does not know the location information of the terminal, which makes the access network device unable to determine the sending direction of the downlink beam. Therefore, when the access network device pages a terminal, it can only send DCI on all paging DCI monitoring opportunities corresponding to the PO of the terminal, and the DCI will schedule the PDSCH that carries the paging message, resulting in a large degree of power consumption of the access network device and a waste of PDSCH time and frequency resources. For example, if the cell is configured with 64 SSB beams, 64 DCI and 64 PDSCH data need to be sent when paging a terminal.

[0041] Therefore, in order to solve the technical problem in the related art that the access network device has a high transmission power consumption and wastes PDSCH time-frequency resources, the embodiment of the present disclosure provides a transmission method, in which the access network device obtains first information, wherein the first information is used to indicate the first location notification area of ​​the target terminal, and obtains multiple downlink beams based on the first location notification area, and determines at least one first beam from the multiple downlink beams, and sends a paging downlink control indication DCI at the paging monitoring opportunity corresponding to the beam direction of the first beam. Since at least one first beam is determined from the multiple downlink beams, and the paging downlink control indication DCI is only sent at the paging monitoring opportunity corresponding to the beam direction of the first beam, the transmission power consumption of the access network device can be effectively reduced, and PDSCH time-frequency resources can be effectively saved.

[0042] The sending method and apparatus provided by the present disclosure are described in detail below with reference to the accompanying drawings. FIG2 is a flow chart of a sending method provided by an embodiment of the present disclosure, which is executed by an access network device, without limitation thereto.

[0043] As shown in FIG2 , the method may include but is not limited to the following steps:

[0044] S201: Acquire first information, where the first information is used to indicate a first location notification area of ​​a target terminal.

[0045] Among them, the terminal to which the paging downlink control indication DCI is to be sent can be called the target terminal. The target terminal can be in an inactive state or in a connected state. The location notification area represents the current activity range of the terminal, and the terminal can notify the access network device after leaving the activity range. The location notification area can be represented as a circular area with the terminal position as the center and the distance D as the radius, as shown in the circle area where the terminal is located on the left of Figure 3. Figure 3 is a schematic diagram of the location notification area in the embodiment of the present disclosure. The location notification area can be covered by one or more downlink beams. The location notification area can also be represented by one or more beam flags in the cell, representing the area covered by the beam set, such as the dotted area shown on the right of Figure 3, where each hexagon represents the coverage range of a beam.

[0046] The location notification area indicating the current activity range of the target terminal may be referred to as the first location notification area. The first information may be used to indicate the first location notification area of ​​the target terminal. For example, identification information indicating the first location notification area, or

[0047] Indicates range information of the first location notification area. For example, the first information is used to indicate the size, dimensions, downlink beam covering the range, downlink beam set covering the range, etc. of the range corresponding to the location notification area where the target terminal is located.

[0048] In some embodiments, when the terminal enters an inactive state, the access network device can configure a location notification area for the terminal. If the terminal is still within the location notification area, the access network device can directly determine the first information based on the local configuration. The first information is used to indicate that the access network device has configured the first location notification area for the terminal, and the scope of the first location notification area can also be known. In other embodiments, if the terminal moves outside the first location notification area, the terminal will report to the access network device an indication that the terminal has moved outside the location notification area, and the access network device will reconfigure the location notification area for the terminal. The reconfigured location notification area can be referred to as the second location notification area. The access network device can determine the first information. The first information is used to indicate the reconfigured location notification area for the target terminal (in this case, the reconfigured second location notification area can also be used as the first location notification area). There is no restriction on this.

[0049] S202: Acquire multiple downlink beams according to the first location notification area.

[0050] In some embodiments, after the access network device learns the first location notification area related to the target terminal, it can refer to the first location notification area to determine multiple downlink beams. For example, based on the range of the first location notification area, multiple downlink beams covering the range can be determined, and multiple downlink beams covering the range can be determined; or, based on the range of the first location notification area, a downlink beam set covering the range can be determined, and multiple downlink beams in the downlink beam set can be determined; of course, any other possible way can be used to refer to the first location notification area to determine multiple downlink beams, such as referring to the identification information of the first location notification area and a preset relationship to determine multiple downlink beams. The preset relationship can be used to describe the correspondence between the identification information and the corresponding multiple downlink beams, and there is no limitation on this.

[0051] S203: Determine at least one first beam from multiple downlink beams.

[0052] In some embodiments, after determining multiple downlink beams, some downlink beams can be selected from the multiple downlink beams, and the selected part of the downlink beams can be referred to as the first beam. For example, in the process of selecting the first beam from the multiple downlink beams, it can be determined whether to send the paging downlink control indication DCI based on the beam scanning method or the paging downlink control indication DCI based on the beam designation method, and then send the paging downlink control indication DCI based on the determined result; or, a preset downlink beam can be determined from the multiple downlink beams as the first beam; of course, the first beam can also be selected from the multiple downlink beams based on any other possible method, such as based on protocol selection, or based on dynamic indication selection, etc., and there is no limitation on this.

[0053] In some embodiments, it can be determined whether a paging message needs to be sent in the beam direction corresponding to each downlink beam. If a paging message needs to be sent, it is determined that a paging DCI needs to be sent at the paging monitoring opportunity corresponding to the beam direction, and the downlink beam corresponding to the beam direction is used as the first beam; if a paging message does not need to be sent, it is determined that a paging DCI does not need to be sent at the paging monitoring opportunity corresponding to the beam direction, and the downlink beam corresponding to the beam direction may not be used as the first beam, and there is no restriction on this.

[0054] In some embodiments, when a PO is about to be sent, the base station integrates the beam scanning paging queue and the beam designated paging queue to determine whether a paging DCI needs to be sent for each paging monitoring opportunity, as well as the content of the DCI-scheduled paging message. If a beam direction does not require a paging message to be sent, then the paging DCI does not need to be sent during the paging monitoring opportunity corresponding to this beam direction.

[0055] S204: Send a paging downlink control indication DCI at a paging monitoring opportunity corresponding to the beam direction of the first beam.

[0056] After determining at least one first beam from the multiple downlink beams, it may trigger the sending of a paging downlink control indication DCI to the terminal at a paging monitoring opportunity corresponding to the beam direction of the first beam.

[0057] In this embodiment, the access network device obtains first information, where the first information is used to indicate a first location notification area of ​​a target terminal, obtains multiple downlink beams based on the first location notification area, determines at least one first beam from the multiple downlink beams, and transmits a downlink paging control indication (DCI) during a paging monitoring opportunity corresponding to the beam direction of the first beam. Because at least one first beam is determined from the multiple downlink beams and the downlink paging control indication (DCI) is only transmitted during a paging monitoring opportunity corresponding to the beam direction of the first beam, the access network device can effectively reduce transmit power consumption and conserve PDSCH time-frequency resources.

[0058] FIG4 is a flow chart of another sending method provided by an embodiment of the present disclosure, which is executed by an access network device and is not limited to this. As shown in FIG4 , the method may include but is not limited to the following steps:

[0059] S401: Receive a connection recovery request message sent by a target terminal, wherein the connection recovery request message has a corresponding receiving beam and the target terminal is in an inactive state.

[0060] In some embodiments, when the terminal enters an inactive state, the access network device may configure a location notification area for the terminal. When the terminal in the inactive state moves outside the location notification area, the terminal may notify the access network device (e.g., a base station) through a location notification area update process. In some embodiments, the location notification area update process may be a multiplexed connection recovery process, as shown in FIG5 , which is a schematic diagram of the location notification area update process in an embodiment of the present disclosure. Taking the access network device as a base station and the target terminal as a UE as an example, the UE may send a connection recovery request message to the base station, and the base station may estimate the location of the UE based on the received connection recovery request message. Optionally, the base station sends a connection release message to the UE.

[0061] In some embodiments, a connection recovery request message may be sent using a data transmission method that switches from an inactive state to a connected state; or a random access based small data transmission method (RA-SDT) may be used to send a connection recovery request message; or a configured grant based small data transmission method (CG SDT) may be used to send a connection recovery request message.

[0062] S402: Determine first location information of the terminal according to the received beam.

[0063] In some embodiments, after receiving a connection restoration request message, if the base station finds that the UE belongs to the base station, the base station may first check the legitimacy of the connection restoration request message according to the stored UE context. If the connection restoration request message is determined to be legitimate, the base station may determine a coarse UE location according to the receive beam of the connection restoration request message, where the coarse UE location may be an optional example of the first location information.

[0064] In other embodiments, after receiving the connection recovery request message, the base station (base station 1) finds that the UE does not belong to this base station, and then initiates a UE context retrieval process to the base station to which the UE belongs (base station 2) to obtain the context of the UE, as shown in Figure 6, which is a schematic diagram of the inter-base station location notification area update process in the embodiment of the present disclosure. The subsequent operations are the same as the scenario where the UE belongs to this base station. After the process is completed, base station 1 initiates a path switching process to the core network to inform the core network that the UE has belonged to base station 1, and then base station 1 requests base station 2 to release the UE context.

[0065] S403: Determine first information according to the first location information and the beam resource configuration, where the first information is used to indicate a first location notification area of ​​the target terminal.

[0066] In some embodiments, since the location notification area can be covered by one or more downlink beams. The location notification area can also be represented by one or more beam flags in the cell, representing the area covered by the beam set. Then, after roughly estimating the first location information, the access network device can determine the part of the downlink beam corresponding to the first location information according to the beam resource configuration, and use the beam flag of the part of the downlink beam to describe the first location notification area (for example, describe the range of the first location notification area), or directly use the part of the downlink beam to describe the first location notification area, without limitation.

[0067] In some embodiments, the access network device may receive second location information sent by the target terminal, wherein the second location information has a greater degree of precision than the first location information, and determine the first information based on the first location information, the second location information, and the beam resource configuration, thereby effectively improving the accuracy of determining the range of the first location notification area. For example, along with a connection recovery request message, the UE may send positioning information to the base station by sending a Radio Resource Control (RRC) message or a Medium Access Control Control Element (MAC CE) message. The positioning information may be referred to as second location information.

[0068] In some embodiments, if the UE optionally sends positioning information, the base station may determine a fine-precision UE location (an optional example of second location information). The base station may determine a location notification area based on the UE location and the base station beam resource configuration.

[0069] S404: Acquire multiple downlink beams according to the first location notification area.

[0070] S405: Determine at least one first beam from multiple downlink beams.

[0071] S406: Send a paging downlink control indication DCI at a paging monitoring opportunity corresponding to the beam direction of the first beam.

[0072] For the description of S404 to S406 , please refer to the above embodiment for details, which will not be repeated here.

[0073] In this embodiment, the access network device obtains first information, wherein the first information is used to indicate the first location notification area of ​​the target terminal, and obtains multiple downlink beams based on the first location notification area, and determines at least one first beam from the multiple downlink beams, and sends a paging downlink control indication DCI at a paging monitoring opportunity corresponding to the beam direction of the first beam. Since at least one first beam is determined from multiple downlink beams, and the paging downlink control indication DCI is only sent at a paging monitoring opportunity corresponding to the beam direction of the first beam, the access network device can effectively reduce the consumption of transmission power and effectively save PDSCH time and frequency resources. By receiving a connection recovery request message sent by the target terminal, wherein the connection recovery request message has a corresponding receiving beam, and determining the first location information of the target terminal based on the receiving beam, and determining the first information based on the first location information and beam resource configuration, the first location notification area can be accurately and quickly determined.

[0074] In some embodiments of the present disclosure, the access network device can also determine the first location information based on the uplink and downlink communication data between the access network device and the target terminal in a connected state, wherein the target terminal enters an inactive state from a connected state, and determines the first information based on the first location information and beam resource configuration, thereby enabling the first location notification area to be flexibly determined.

[0075] In some embodiments of the present disclosure, the access network device may also determine second information, wherein the second information is used to indicate triggering a location notification area update process and sending a connection release message to the target terminal, wherein the connection release message includes at least: new inactive configuration parameters, and the new inactive configuration parameters are used to configure a second location notification area for the target terminal, thereby enabling timely updating of the location notification area of ​​the target terminal to support accurate sending of the paging downlink control indication DCI.

[0076] For example, taking the target terminal as a UE, if the UE's inactive state configuration parameters change, such as a change in the location notification area indicated by the beam flag, the base station may send a connection release message to the UE, carrying the new inactive state configuration parameters, to instruct the UE to return to the inactive state and trigger the configuration of a second location notification area for the target terminal. The second location notification area may be, for example, an updated location notification area. If the UE's inactive state configuration parameters do not change, the base station may not send a connection release message, and the UE remains in the inactive state, using the existing inactive state configuration parameters.

[0077] In some embodiments of the present disclosure, when sending a connection release message to a target terminal, the access network device may determine a second beam from multiple downlink beams based on the first location information, and send a connection release message to the target terminal based on the second beam, thereby enabling the access network device to refer to the coarse-precision location or optional fine-precision location of the terminal and use a reasonable downlink beam to send the connection release message.

[0078] In some embodiments of the present disclosure, the access network device may also determine the scope of the second location notification area to facilitate configuring an appropriate second location notification area for the target terminal. In some embodiments of the present disclosure, a trigger frequency value for the location notification area update process may be determined, where the trigger frequency value is used to describe how frequently the location notification area update process is triggered. Based on the trigger frequency value, the scope of the second location notification area is determined, thereby improving the accuracy and rationality of determining the scope of the second location notification area.

[0079] The trigger frequency describes how often the location notification area update process is triggered. A higher trigger frequency indicates that the location notification area update process is triggered more frequently. The range of the second location notification area can be adaptively determined based on the frequency with which the location notification area update process is triggered.

[0080] In some embodiments of the present disclosure, if the trigger frequency value is greater than or equal to the first frequency threshold, it is determined that the range of the second location notification area is greater than the range of the first location notification area; if the trigger frequency value is less than or equal to the second frequency threshold, it is determined that the range of the second location notification area is smaller than the range of the first location notification area, wherein the first frequency threshold is greater than the second frequency threshold.

[0081] The first frequency threshold is a frequency threshold value indicating a high frequency level. The second frequency threshold is a frequency threshold value indicating a low frequency level. If the location notification area update process is triggered frequently, a larger location notification area may be configured for the target terminal. If the location notification area update process is triggered less frequently, a smaller location notification area may be configured for the target terminal.

[0082] For example, the base station can adjust the location notification area range according to the frequency of the location notification area update process of the UE. For example, a high water level threshold N (an optional example of the first frequency threshold) and a low water level threshold M (an optional example of the second frequency threshold) are configured, and N>M. During this location notification area update process, if the UE has initiated N location notification area update processes within the previous T time, the base station configures a larger location notification area in this location notification area update process; if the UE has initiated less than M location notification area update processes within the previous T time, the base station configures a smaller location notification area in this location notification area update process.

[0083] In some embodiments of the present disclosure, the connection release message also includes: third information, wherein the third information is used to indicate whether the target terminal needs to update the location notification area after cell reselection, thereby effectively improving the flexibility of the location notification area configuration and effectively applying it to personalized communication scenarios.

[0084] In some embodiments of the present disclosure, if it is determined that the first location information and / or the second location information are not within the coverage of the service cell, the first location information is deleted, wherein the third information is used to indicate that the target terminal does not need a location notification area update after cell reselection, which can effectively reduce the storage resource consumption of the first location information and is effectively applicable to personalized communication scenarios.

[0085] For example, in a non-geostationary orbit (NTN) scenario, the base station moves at high speed relative to the ground. The base station can configure in the connection release message whether the UE requires a location notification area update after cell reselection. If the update is configured to be required, the UE can initiate a location notification area update after detecting cell reselection, as shown in Figure 6 above. If the update is not configured to be required, the UE does not initiate a location notification area update after detecting cell reselection. If the base station detects that the UE is no longer within the cell coverage area after moving, it can delete the UE's location information.

[0086] FIG7 is a flow chart of another sending method provided by an embodiment of the present disclosure, which is executed by an access network device and is not limited to this. As shown in FIG7 , the method may include but is not limited to the following steps:

[0087] S701: Acquire first information, where the first information is used to indicate a first location notification area of ​​a target terminal.

[0088] S702: Acquire multiple downlink beams according to the first location notification area.

[0089] S703: If the target terminal identifier belongs to at least one candidate terminal identifier in the beam scanning paging queue, determine at least one first beam according to multiple downlink beams, wherein the target terminal identifier is used to identify the target terminal.

[0090] In some embodiments, if the target terminal identifier belongs to at least one candidate terminal identifier in the beam scanning paging queue, multiple downlink beams are all used as the first beam.

[0091] S704: If the target terminal identifier belongs to at least one candidate terminal identifier in the beam-specified paging queue, determine at least one first beam from multiple downlink beams according to the target terminal identifier and the beam-specified paging queue.

[0092] In some embodiments, the beam-designated paging queue also includes: a beam identifier corresponding to each candidate terminal identifier; if the target terminal identifier belongs to at least one candidate terminal identifier in the beam-designated paging queue, then determining the candidate terminal identifier that matches the target terminal identifier from at least one candidate terminal identifier in the beam-designated paging queue, and determining the beam identifier corresponding to the matching candidate terminal identifier, and determining the downlink beam to which the corresponding beam identifier belongs from multiple downlink beams as the first beam.

[0093] In some embodiments, before obtaining the first information, if the access network device does not know the initial location information of the target terminal, the target terminal identifier can be added to the beam scanning paging queue; if the access network device knows the initial location information of the target terminal, the beam identifier corresponding to the target terminal identifier is determined, and the target terminal identifier and the corresponding beam identifier are added to the beam designated paging queue.

[0094] In some embodiments, the beam scanning paging queue includes: at least one candidate terminal identifier, and the beam designation paging queue includes: at least one candidate terminal identifier, and a beam identifier corresponding to each candidate terminal identifier.

[0095] The description of S703-S704 can be exemplified as follows:

[0096] In some embodiments, a beam scanning paging queue and a beam designated paging queue may be pre-formed. The beam scanning paging queue may indicate that a paging downlink control indication DCI is sent to the terminal therein based on a beam scanning method, while the beam designated paging queue may indicate that a paging downlink control indication DCI is sent to the corresponding terminal based on a designated beam.

[0097] For example, the beam scanning paging queue can be expressed as {UE1, UE2}, where UE1 and UE2 can be optional examples of candidate terminal identifiers. The beam specified paging queue can be expressed as {{beam 4, UE3}, {beam 5, UE3}, {beam 5, UE4}, {beam 6, UE4}}, where UE3, UE4, and UE5 can be optional examples of candidate terminal identifiers, beam 4 is a beam identifier corresponding to UE3, beam 5 is another beam identifier corresponding to UE3, beam 5 is a beam identifier corresponding to UE4, and beam 6 is another beam identifier corresponding to UE4. The beam scanning paging queue {UE1, UE2} indicates that a paging downlink control indication DCI is sent to UE1 and UE2 based on the beam scanning mode (i.e., based on all downlink beams). The beam specified paging queue {{beam 4, UE3}, {beam 5, UE3}, {beam 5, UE4}, {beam 6, UE4}} indicates that paging downlink control indication DCI is sent to UE3 based on beam 4 and beam 5, and paging downlink control indication DCI is sent to UE4 based on beam 5 and beam 6.

[0098] In some embodiments, the method for determining the beam scanning paging queue and the beam designated paging queue can be as shown in Figure 8, which is a schematic diagram of the paging processing flow chart in an embodiment of the present disclosure. When the base station receives downlink data of a candidate UE (the candidate UE can be an optional example of a candidate terminal) from the core network through the NG interface, or receives a paging request for a candidate UE from a neighboring base station through the Xn interface, a paging request from the core network for the idle candidate UE is added to the processing flow, and it is assumed that the base station does not know the location information of the idle candidate UE. If the base station does not have the location information of the candidate UE, the PO where the candidate UE is located adopts the beam scanning paging method, and the candidate UE flag can be added to the beam scanning paging queue. If the base station has the location information of the candidate UE, the downlink transmission beam list is determined according to the location information of the candidate UE, and the candidate UE flag is added to the beam designated paging queue. Among them, the candidate UE flag is an optional example of the candidate terminal identifier. "N" means no, and "Y" means yes.

[0099] After forming the beam scanning paging queue and / or beam designated paging queue, at least one first beam can be determined from multiple downlink beams with reference to the identifier of the target terminal, the beam scanning paging queue and / or the beam designated paging queue, so as to accurately and quickly determine at least one first beam from multiple downlink beams.

[0100] In some embodiments, if the target terminal identifier belongs to at least one candidate terminal identifier in the beam scanning paging queue, multiple downlink beams are all used as the first beam.

[0101] In some embodiments, if the target terminal identifier belongs to at least one candidate terminal identifier in the beam-specified paging queue, the candidate terminal identifier that matches the target terminal identifier is determined, and the beam identifier corresponding to the matching candidate terminal identifier is determined, and the downlink beam to which the corresponding beam identifier belongs is determined from multiple downlink beams as the first beam.

[0102] For example, when a PO is about to be sent, the base station integrates the beam scanning paging queue and the beam designated paging queue to determine whether a paging DCI needs to be sent for each paging monitoring opportunity, as well as the content of the DCI-scheduled paging message. If a certain beam direction does not need to send a paging message, the paging DCI can be not sent during the paging monitoring opportunity corresponding to this beam direction.

[0103] The following three scenarios are used as examples to illustrate how to construct a paging message.

[0104] Scenario 1: Beam scanning paging queue {UE1, UE2}, beam designated paging queue {{beam 4, UE3}, {beam 5, UE3}, {beam 5, UE4}, {beam 6, UE4}}.

[0105] Scenario 2: Beam scans the paging queue {UE1, UE2}, and the beam-specified paging queue is empty.

[0106] Scenario 3: The beam scanning paging queue is empty, and the beam specified paging queue is {{beam 4, UE3}, {beam 5, UE3}, {beam 5, UE4}, {beam 6, UE4}}.

[0107] For scenario 1, the two queues are combined at the beam granularity, as shown in Figure 9. Figure 9 is a schematic diagram of paging scheduling in an embodiment of the present disclosure. For scenario 3, paging DCI and paging messages are sent only on required beams.

[0108] S705: Send a paging downlink control indication DCI at a paging monitoring opportunity corresponding to the beam direction of the first beam.

[0109] In this embodiment, the access network device obtains first information, wherein the first information is used to indicate the first location notification area of ​​the target terminal, and obtains multiple downlink beams based on the first location notification area, and determines at least one first beam from the multiple downlink beams, and sends a paging downlink control indication DCI at a paging monitoring opportunity corresponding to the beam direction of the first beam. Since at least one first beam is determined from multiple downlink beams, and the paging downlink control indication DCI is only sent at a paging monitoring opportunity corresponding to the beam direction of the first beam, the access network device can effectively reduce the consumption of transmission power and effectively save PDSCH time and frequency resources. By pre-forming a beam scanning paging queue and / or a beam designated paging queue, wherein the beam scanning paging queue includes: at least one candidate terminal identifier, and the beam designated paging queue includes: at least one candidate terminal identifier, and a beam identifier corresponding to each candidate terminal identifier. If the target terminal identifier belongs to at least one candidate terminal identifier in the beam scanning paging queue, at least one first beam is determined based on multiple downlink beams. If the target terminal identifier belongs to at least one candidate terminal identifier in the beam designated paging queue, at least one first beam is determined from multiple downlink beams based on the target terminal identifier and the beam designated paging queue, thereby achieving rapid and accurate selection of at least one first beam from multiple downlink beams, and at the same time improving the sending flexibility of the paging downlink control indication DCI, which is effectively suitable for personalized communication scenarios.

[0110] In the disclosed embodiments, a location notification area is proposed. This area can be represented by a circle with the UE location as the center and a distance D as the radius; it can also be represented by multiple beam markers within a cell. When a UE enters an inactive state, the base station configures a location notification area. After an inactive UE leaves the location notification area, it can update its location to the base station through the location notification area update process. The UE updates its location to the base station through the location notification area update process. The base station can determine the UE's coarse-precision location based on the uplink receive beam direction. Optionally, the UE can also report its own positioning information to assist the base station in obtaining the UE's fine-precision location.

[0111] When there is no need to change the UE inactive configuration parameters, the connection release message in the location notification area update process may not be sent. The coverage of the location notification area can be adjusted according to the frequency of the UE's location notification area update process.

[0112] In the disclosed embodiments, the base station can determine the downlink beam set available to the UE based on the UE's location and location notification area, combined with the base station's downlink beam configuration, and construct a beam scanning paging queue and a beam designated paging queue. Based on this, the base station determines the PO's paging DCI monitoring timing and paging message content by integrating all paged UE information on the PO. This can reduce the number of paging DCI and paging messages sent, as well as the length of paging messages, saving base station power consumption and improving base station time and frequency resource utilization.

[0113] FIG10 is a flow chart of a receiving method provided by an embodiment of the present disclosure, which is executed by a terminal and is not limited to this. As shown in FIG10 , the method may include but is not limited to the following steps:

[0114] S1001: Receive a paging downlink control indication DCI, wherein the paging DCI is sent at a paging monitoring opportunity corresponding to a beam direction of at least one first beam among multiple downlink beams, and the multiple downlink beams are determined based on first information, and the first information is used to indicate a first location notification area of ​​the terminal.

Because at least one first beam is determined from the multiple downlink beams and the paging downlink control indication (DCI) is sent only during a paging monitoring opportunity corresponding to the beam direction of the first beam, transmit power consumption of an access network device can be effectively reduced, and PDSCH time-frequency resources can be effectively conserved.

[0117] In some embodiments of the present disclosure, the terminal may send a connection recovery request message to the access network device, wherein the connection recovery request message has a corresponding receiving beam, the receiving beam is used to determine the first location information of the terminal, and the first location information and the beam resource configuration are used to determine the first information.

Because at least one first beam is determined from the multiple downlink beams and the downlink paging control indication (DCI) is only transmitted during a paging monitoring opportunity corresponding to the beam direction of the first beam, the access network device can effectively reduce transmit power consumption and conserve PDSCH time-frequency resources.
