Description

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

Technical Field

The present disclosure relates to the field of communications technologies, and in particular, to a sending method, a receiving method, an apparatus, a device, and a storage medium.

Background

In mobile communication, the states of terminals can be classified into an idle state, a connected state, and an inactive state. In the inactive state, the terminal and the core network remain connected, and no connection exists between the terminal and the access network. When the terminal enters an inactive state, the access network configures a radio access network notification area (Radio Access Network based Notification Area, RNA) for the terminal, comprising one or more cells. After the terminal enters the inactive state, if the terminal home cell receives downlink service data or signaling data from the core network for the terminal, the home cell informs the terminal in the own cell through paging information. If the RNA contains multiple cells, the home cell sends a message to other cells within the RNA to require the other cells to page the terminal synchronously. When the terminal leaves the RNA, the terminal may initiate a radio access network notification area Update (RAN-based Notification Area Update, RNA Update) procedure, reporting the latest home cell of the terminal to the access network.

In order to better understand a transmission method disclosed in an embodiment of the present disclosure, a description is first given below of a communication system to which the embodiment of the present disclosure is applicable.

Referring to fig. 1, fig. 1 is a schematic architecture diagram of a communication system according to an embodiment of the disclosure. The communication system may include, but is not limited to, an access network device and a terminal, and the number and form of devices shown in fig. 1 are only for example and not meant to limit the embodiments of the present disclosure, and in practical applications, two or more access network devices and two or more terminals may be included.

For example: a long term evolution (long term evolution, LTE) system, a fifth generation (5th generation,5G) mobile communication system, a 5G New Radio (NR) system, or other future new mobile communication systems, etc.

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 may be an evolved NodeB (eNB), a transmission and reception point (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 (wireless fidelity, wiFi) system, or the like. The specific technology and specific device configuration employed by the access network device in the embodiments of the present disclosure are not limited.

The access network device provided by the embodiment of the disclosure may be composed of a Central Unit (CU) and a Distributed Unit (DU), where the CU may also be referred to as a control unit (control unit), the protocol layers of the access network device, such as a base station, may be detached by adopting a CU-DU structure, functions of part of the protocol layers are placed in the CU for centralized control, and functions of part or all of the protocol layers are distributed in the DU, so that the CU centrally controls the DU.

The terminal 102 in the embodiments of the present disclosure is an entity on the user side for receiving or transmitting signals, such as a mobile phone. A terminal may also be referred to as a terminal (terminal), a User Equipment (UE), a Mobile Station (MS), a Mobile Terminal (MT), etc. The terminal may be a car with communication function, a smart car, a mobile phone, a wearable device, a tablet (Pad), a computer with wireless transceiving function, a Virtual Reality (VR) terminal, an augmented reality (augmented reality, AR) terminal, a wireless terminal in industrial control (industrial control), a wireless terminal in unmanned driving (self-driving), a wireless terminal in teleoperation (remote medical surgery), a wireless terminal in smart grid (smart grid), a wireless terminal in transportation security (transportation safety), a wireless terminal in smart city (smart city), a wireless terminal in smart home (smart home), etc.

The embodiment of the disclosure does not limit the specific technology and the specific equipment form adopted by the terminal.

It may be understood that, the communication system described in the embodiments of the present disclosure is for more clearly describing the technical solutions of the embodiments of the present disclosure, and is not limited to the technical solutions provided in the embodiments of the present disclosure, and those skilled in the art can know that, with the evolution of the system architecture and the appearance of new service scenarios, the technical solutions provided in the embodiments of the present disclosure are equally applicable to similar technical problems.

In the related art, a terminal in an inactive state monitors Paging Occasions (POs) of an access network in each discontinuous reception (Discontinuous Reception, DRX) cycle, so as to acquire a service establishment requirement or a cell message update indication in time. The paging occasions are a set of physical downlink control channel (Physical Downlink Control Channel, PDCCH) listening occasions for carrying paging downlink control indications (Downlink Control Indicator, DCI). The Paging Frame (PF) contains one or more POs, or the start position of a PO. The paging DCI is used to schedule PDSCH carrying paging messages and/or indicate paging short messages. Each PO contains a set of S consecutive paging DCI listening occasions, where S is the number of synchronization signals and physical broadcast channel blocks (Synchronization Signal and Physical Broadcast Channel block, SSB) actually transmitted in the cell. The kth listening occasion in the PO corresponds to the actually transmitted kth SSB, whereby different listening occasions in the PO correspond to different beam directions, so that paging scheduling information and/or paging short message indications are transmitted at all listening occasions in one PO, i.e. beam scanning of one paging procedure is completed. The terminal may assume that the paging messages sent at all listening occasions in one PO are the same.

In some application scenarios, the number of SSBs actually transmitted by the cell is larger, for example, in a terrestrial millimeter wave scenario, and the maximum number of SSBs that can be transmitted is 64. In a Non-terrestrial network (Non-Terrestrial Network, NTN) scenario, the number of SSBs is larger. Thus, the paging DCI listening occasion that each PO contains increases accordingly. When the terminal is in an inactive state, the access network equipment can only know the RNA in which the terminal is located, but the position information of the terminal is not clear, so that the access network equipment cannot determine the sending direction of the downlink beam. Therefore, when the access network device pages a certain terminal, the DCI can only be sent on all paging DCI monitoring occasions of the terminal corresponding to the POs, and the DCI will schedule the PDSCH carrying the paging message, resulting in a larger transmission power consumption degree of the access network device and wasting PDSCH time-frequency resources. For example, if a cell configures 64 SSB beams, 64 pieces of DCI and 64 pieces of PDSCH data need to be transmitted when paging a certain terminal.

Therefore, in the embodiments of the present disclosure, in order to solve the technical problem that the transmission power consumption of the access network device in the related art is high and the PDSCH time-frequency resource is wasted, a transmission method is provided, where 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 a plurality of downlink beams according to the first location notification area, determines at least one first beam from the plurality of downlink beams, and transmits paging downlink control indication DCI at a paging listening occasion corresponding to the beam direction of the first beam. Since at least one first beam is determined from the plurality of downlink beams, and the paging downlink control indication DCI is sent only at the paging listening occasion corresponding to the beam direction of the first beam, the consumption degree of the sending power of the access network device can be effectively reduced, and the PDSCH time-frequency resource can be effectively saved.

The transmission method and the device thereof provided by the present disclosure are described in detail below with reference to the accompanying drawings. Fig. 2 is a flow chart of a transmission method provided in an embodiment of the disclosure, where the method is performed by an access network device, and this is not a limitation.

As shown in fig. 2, the method may include, but is not limited to, the steps of:

s201: and acquiring first information, wherein the first information is used for indicating a first position notification area of the target terminal.

A terminal to which paging downlink control indication DCI is to be transmitted may be referred to as a target terminal. The target terminal may be in an inactive state or in a connected state. The location notification area indicates 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 may be represented as a circular area with the location of the terminal as the center and the distance D as the radius, such as the circular area where the terminal is located as shown in the left part of fig. 3, and fig. 3 is a schematic diagram of the location notification area in the embodiment of the present disclosure. The location notification area may be covered by one or more downlink beams. The location notification area may also be represented by one or more beam markers within the cell, representing the area covered by the beam set, as shown by the dashed area on the right in fig. 3, where each hexagon represents the coverage of one beam.

Wherein the location notification area representing the current active area of the target terminal may be referred to as a first location notification area. The first information may be used to indicate a first location notification area of the target terminal. Such as identification information indicating a first location notification area, or

Range information indicating the first position notification area. For example, the first information is used to indicate the size and the dimension of the range corresponding to the location notification area where the target terminal is located, the downlink beam covering the range, the downlink beam set covering the range, and so on.

In some embodiments, when the terminal enters the inactive state, the access network device may configure a location notification area for the terminal, and if the terminal is still within the location notification area, the access network device may determine first information directly based on the local configuration, where the first information is used to indicate the first location notification area configured by the access network device for the terminal, and may also learn the range of the first location notification area. In other embodiments, if the terminal moves outside the first location notification area, the terminal reports to the access network device an indication that the terminal has moved outside the location notification area, and the access network device reconfigures the location notification area for the terminal, where the reconfigured location notification area may be referred to as a second location notification area. The access network device may determine first information indicating a location notification area reconfigured for the target terminal (at this time, the reconfigured second location notification area may also be referred to as the first location notification area), which is not limited.

S202: and acquiring a plurality of downlink beams according to the first position notification area.

In some embodiments, after learning the first location notification area related to the target terminal, the access network device may refer to the first location notification area to determine a plurality of downlink beams. For example, a plurality of downlink beams covering the range may be determined according to the range of the first location notification area, and a plurality of downlink beams covering the range may be determined; or, a downlink beam set covering the range can be determined according to the range of the first position notification area, and a plurality of downlink beams in the downlink beam set are determined; of course, the plurality of downlink beams may be determined by referring to the first location notification area in any other possible manner, for example, the plurality of downlink beams may be determined by referring to the identification information of the first location notification area and a preset relationship, and the preset relationship may be used to describe a correspondence between the identification information and the corresponding plurality of downlink beams, which is not limited.

S203: at least one first beam is determined from the plurality of downlink beams.

In some embodiments, after determining the plurality of downstream beams, a portion of the downstream beams may be selected from the plurality of downstream beams, and the selected portion of the downstream beams may be referred to as a first beam. For example, in the process of selecting the first beam from the plurality of downlink beams, whether to transmit the paging downlink control indication DCI based on the beam scanning mode or to transmit the paging downlink control indication DCI based on the beam specifying mode may be determined, and then the paging downlink control indication DCI is transmitted according to the determined result; or determining a preset downlink wave beam from a plurality of downlink wave beams as a first wave beam; of course, the first beam may be selected from the plurality of downstream beams based on any other possible manner, such as based on a protocol selection, or based on a dynamic indication selection, etc., without limitation.

In some embodiments, it may be determined whether a paging message needs to be sent in a beam direction corresponding to each downlink beam, if a paging message needs to be sent, it is determined that paging DCI needs to be sent at a paging listening occasion corresponding to the beam direction, and then the downlink beam corresponding to the beam direction is used as the first beam; if the paging message is not required to be sent, it is determined that the paging DCI is not required to be sent at the paging listening occasion corresponding to the beam direction, and the downlink beam corresponding to the beam direction may not be used as the first beam, which is not limited.

In some embodiments, when a PO is near to transmission, the base station combines the beam scanning paging queue and the beam designating paging queue, determines whether each paging listening occasion requires transmission of paging DCI, and the paging message content of the DCI schedule. If a certain beam direction does not need to send paging messages, paging DCI does not need to be sent at the paging listening occasion corresponding to the beam direction.

S204: and sending paging downlink control indication DCI at a paging listening occasion corresponding to the beam direction of the first beam.

After determining at least one first beam from the plurality of downlink beams, the method may trigger sending paging downlink control indication DCI to the terminal at a paging listening occasion corresponding to a beam direction of the first beam.

In this embodiment, the access network device obtains the first information, where the first information is used to indicate a first location notification area of the target terminal, obtains a plurality of downlink beams according to the first location notification area, determines at least one first beam from the plurality of downlink beams, and sends paging downlink control indication DCI at a paging listening occasion corresponding to a beam direction of the first beam. Since at least one first beam is determined from the plurality of downlink beams, and the paging downlink control indication DCI is sent only at the paging listening occasion corresponding to the beam direction of the first beam, the consumption degree of the sending power of the access network device can be effectively reduced, and the PDSCH time-frequency resource can be effectively saved.

Fig. 4 is a flowchart of another transmission method provided in an embodiment of the disclosure, where the method is performed by an access network device, and this is not a limitation. As shown in fig. 4, the method may include, but is not limited to, the steps of:

s401: and receiving a connection recovery request message sent by the target terminal, wherein the connection recovery request message has a corresponding receiving beam, and the target terminal is in an inactive state.

In some embodiments, the access network device may configure the location notification area for the terminal when the terminal enters the inactive state. When a terminal in an inactive state moves outside the location notification area, the terminal may notify an access network device (e.g., a base station) through a location notification area update procedure. In some embodiments, the location notification area update procedure may be a multiplexed connection recovery procedure, as shown in fig. 5, and fig. 5 is a schematic diagram of the location notification area update procedure in the 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 restoration request message to the base station, and the base station may estimate the location of the UE based on the received connection restoration request message. Optionally, the base station sends a connection release message to the UE.

In some embodiments, the connection recovery request message may be sent by adopting a data transmission mode that the inactive state enters the connected state; or a small data transmission mode (Random Access based Small Data Transmission, RA-SDT) based on random access can be adopted to send a connection recovery request message; or may send a connection restoration request message based on the small data transfer mode (Configured Grant based Small Data Transmission, CG SDT) for which the authorization is configured.

S402: first location information of the terminal is determined from the receive beam.

In some embodiments, after receiving the connection restoration request message, if the UE is found to belong to the base station, the base station may first check the validity of the connection restoration request message according to the stored UE context. If it is determined that the connection restoration request message is legal, the base station may determine a coarse UE location according to a reception beam of the connection restoration request message, wherein the coarse UE location may be an optional example of the first location information.

In other embodiments, after receiving the connection restoration request message, the base station (base station 1) discovers that the UE does not belong to the base station, and initiates a UE context searching procedure to the UE-belonging base station (base station 2) to obtain the context of the UE, as shown in fig. 6, fig. 6 is a schematic diagram of an inter-base station notification area updating procedure in the embodiments of the present disclosure. The subsequent operation is the same as the UE belongs to the present base station scenario. After the process is completed, the base station 1 initiates a path switching process to the core network, so that the core network knows that the UE is already attributed to the base station 1, and then the base station 1 requests the base station 2 to release the UE context.

S403: and determining first information according to the first position information and the beam resource configuration, wherein the first information is used for indicating a first position notification area of the target terminal.

In some embodiments, the location notification area may be covered by one or more downlink beams. The location notification area may also be represented by one or more beam marks in the cell, which represent an area covered by the beam set, and after roughly estimating the first location information, the access network device may determine a part of downlink beams corresponding to the first location information according to the beam resource configuration, and describe the first location notification area by using the beam mark of the part of downlink beams (for example, describe the range of the first location notification area), or describe the first location notification area directly by using the part of downlink beams, which is not limited.

In some embodiments, the access network device may receive second location information sent by the target terminal, where the fineness degree of the second location information is greater than that of the first location information, and determine the first information according to the first location information, the second location information, and the beam resource configuration, so that accuracy of determining the range of the first location notification area can be effectively improved. For example, with the connection restoration request message, the UE may transmit positioning information to the base station by transmitting a radio resource control (Radio Resource Control, RRC) message or a control element (Medium Access Control Control Element, MAC CE) message of medium access control, or the like. The positioning information may be referred to as second location information.

In some embodiments, the base station may determine a fine-precision UE location (an alternative example of second location information) if the UE optionally sent positioning information. The base station may determine a location notification area in combination with the UE location and the base station beam resource configuration.

S404: and acquiring a plurality of downlink beams according to the first position notification area.

S405: at least one first beam is determined from the plurality of downlink beams.

S406: and sending paging downlink control indication DCI at a paging listening occasion corresponding to the beam direction of the first beam.

The descriptions of S404-S406 may be specifically referred to the above embodiments, and are not repeated here.

In this embodiment, the access network device obtains the first information, where the first information is used to indicate a first location notification area of the target terminal, obtains a plurality of downlink beams according to the first location notification area, determines at least one first beam from the plurality of downlink beams, and sends paging downlink control indication DCI at a paging listening occasion corresponding to a beam direction of the first beam. Since at least one first beam is determined from the plurality of downlink beams, and the paging downlink control indication DCI is sent only at the paging listening occasion corresponding to the beam direction of the first beam, the consumption degree of the sending power of the access network device can be effectively reduced, and the PDSCH time-frequency resource can be effectively saved. By receiving the connection recovery request message sent by the target terminal, wherein the connection recovery request message has a corresponding receiving beam, determining the first position information of the target terminal according to the receiving beam, and determining the first information according to the first position information and the beam resource configuration, the first position notification area can be accurately and rapidly determined.

In some embodiments of the present disclosure, the access network device may further determine first location information according to uplink and downlink communication data of the access network device and the target terminal in a connection state, where the target terminal enters an inactive state from the connection state, and determine the first information according to the first location information and the beam resource configuration, so that flexible determination of the first location notification area can be implemented.

In some embodiments of the present disclosure, the access network device may further determine second information, where the second information is used to indicate to trigger a location notification area update procedure, and send a connection release message to the target terminal, where the connection release message includes at least: the new inactive state configuration parameters are used for configuring the second position notification area for the target terminal, so that the position notification area of the target terminal is updated timely, and accurate transmission of paging downlink control indication DCI is supported.

For example, taking the target terminal as the UE to perform an example, if the inactive state configuration parameter of the UE changes, for example, the location notification area indicated by the beam mark changes, the base station may send a connection release message to the UE, carrying the new inactive state configuration parameter, so as to instruct the UE to return to the inactive state, and trigger to configure the second location notification area for the target terminal. The second location notification area may be, for example, an updated location notification area. If the configuration parameters of the inactive state of the UE do not change, the base station may not send a connection release message, and the UE is still in the inactive state, and adopts the existing configuration parameters of the inactive state.

In some embodiments of the present disclosure, in the process of sending the connection release message to the target terminal, the access network device may determine a second beam from the multiple downlink beams according to the first location information, and send the connection release message to the target terminal based on the second beam, so that the access network device can send the connection release message by using a reasonable downlink beam with reference to the coarse precision location or the optional fine precision location of the terminal.

In some embodiments of the present disclosure, the access network device may also determine the range of the second location notification area in order to configure a suitable second location notification area for the target terminal. In some embodiments of the present disclosure, a trigger frequency value of a location notification area update procedure may be determined, where the trigger frequency value is used to describe how frequently the location notification area update procedure is triggered, and determine a range of a second location notification area according to the trigger frequency value, thereby improving accuracy and rationality of determining the range of the second location notification area.

The trigger frequency is used for describing the frequency condition that the update flow of the position notification area is triggered. The higher the trigger frequency, the more frequently the location notification area update procedure is triggered. The range of the second location notification area may be adaptively determined with reference to how frequently the location notification area update procedure is triggered.

In some embodiments of the present disclosure, if the trigger frequency value is greater than or equal to a first frequency threshold, the range of the second location notification area is determined to be greater than the range of the first location notification area, and if the trigger frequency value is less than or equal to a second frequency threshold, the range of the second location notification area is determined to be less than the range of the first location notification area, wherein the first frequency threshold is greater than the second frequency threshold.

The first frequency threshold is a threshold frequency value indicating a high frequency. The second frequency domain threshold is a threshold frequency value indicating a low frequency. If the frequency of the triggered position notification area updating flow is high, a large position notification area can be configured for the target terminal, and if the frequency of the triggered position notification area updating flow is low, a small position notification area can be configured for the target terminal.

For example, the base station may adjust the location notification area range according to how often the UE generates the location notification area update procedure. For example, a high water level threshold N (an alternative example of a first frequency threshold) and a low water level threshold M (an alternative example of a second frequency threshold) are configured, with N > M. When the current position notification area updating process is performed, if the UE initiates N times of position notification area updating processes in the previous T time, the base station configures a larger position notification area in the current position notification area updating process; if the UE initiates the updating flow of the position notification area for less than M times in the previous T time, the base station configures a smaller position notification area in the updating flow of the position notification area.

In some embodiments of the present disclosure, the connection release message further includes: and the third information is used for indicating whether the target terminal needs to update the position notification area after the cell reselection, so that the flexibility of the position notification area configuration can be effectively improved, and the method is effectively applicable to personalized communication scenes.

In some embodiments of the present disclosure, if it is determined that the first location information and/or the second location information is not within the coverage area of the serving cell, the first location information is deleted, where the third information is used to indicate that the target terminal does not need to update the location notification area after cell reselection, which can effectively reduce storage resource consumption of the first location information and is effectively suitable for a personalized communication scenario.

Illustratively, in non-geostationary orbit scenarios of NTN, the base station moves at high speed relative to the ground. The base station may configure in the connection release message whether the UE needs a location notification area update after cell reselection. If configured to require an update, the UE may initiate a location notification area update after detecting a cell reselection, as illustrated in fig. 6 above. If configured not to require an update, the UE does not initiate a location notification area update after detecting a cell reselection. After the base station moves, if the position of the UE is found to be not in the coverage area of the cell, the position information of the UE can be deleted.

Fig. 7 is a flowchart of another transmission method provided in an embodiment of the disclosure, where the method is performed by an access network device, and this is not a limitation. As shown in fig. 7, the method may include, but is not limited to, the steps of:

s701: and acquiring first information, wherein the first information is used for indicating a first position notification area of the target terminal.

In some embodiments, before the first information is acquired, if the access network device does not know the initial location information of the target terminal, the target terminal identifier is added to the beam scanning paging queue; if the access network equipment knows the initial position information of the target terminal, determining a beam identifier corresponding to the target terminal identifier, and adding the target terminal identifier and the corresponding beam identifier into a beam designated paging queue.

In some embodiments, beam scanning the paging queue comprises: at least one candidate terminal identification, the beam-specific paging queue comprising: at least one candidate terminal identity, and a beam identity corresponding to each candidate terminal identity.

The description explanation for S703 to S704 may be exemplified as follows:

in some embodiments, beam scanning paging queues may be preformed and beam specific paging queues determined. The beam scanning paging queue may indicate that paging downlink control indication DCI is sent to the terminal therein based on the beam scanning manner, and the beam designating paging queue may indicate that paging downlink control indication DCI is sent to the corresponding terminal based on the designated beam.

The beam scanning paging queue may be represented as { UE1, UE2}, where UE1, UE2 may be an alternative example of a candidate terminal identity. The beam-specific paging queue may be expressed as { beam 4, UE3}, { beam 5, UE4}, { beam 6, UE4}, where UE3, UE4, UE5 may be an alternative example of candidate terminal identities, beam 4 is one beam identity corresponding to UE3, beam 5 is another beam identity corresponding to UE3, beam 5 is one beam identity corresponding to UE4, and beam 6 is another beam identity corresponding to UE 4. Beam scanning paging queues { UE1, UE2}, means that paging downlink control indication DCI is sent for UE1, UE2 based on the beam scanning scheme (i.e. based on all downlink beams). The beam assignment paging queue { { { beam 4, UE3}, { beam 5, UE4}, { beam 6, UE4}, indicates that paging downlink control indication DCI is transmitted for UE3 based on beam 4 and beam 5, and paging downlink control indication DCI is transmitted for UE4 based on beam 5 and beam 6.

In some embodiments, the manner in which the paging queues are scanned for the beams and the paging queues are specified for the beams may be as shown in fig. 8, fig. 8 being a flow chart diagram of the paging process in an embodiment of the present disclosure. When the base station receives downlink data of a candidate UE (the candidate UE may be an optional example of a candidate terminal) from the core network through the NG interface, or receives a paging request of a certain candidate UE from the neighboring base station through the Xn interface, a paging request from the core network for an idle state candidate UE is added in the processing flow, and the base station is considered to be unaware of location information of the idle state candidate UE. If the base station does not have the position information of the candidate UE, the PO of the candidate UE is adopted in a beam scanning paging mode, and the candidate UE mark can be added into a beam scanning paging queue. If the base station has the position information of the candidate UE, determining a downlink sending beam list according to the position information of the candidate UE, and adding the candidate UE mark into a beam appointed paging queue. Wherein the candidate UE identity is an alternative example of a candidate terminal identity. "N" means no, and "Y" means yes.

After the beam scanning paging queue and/or the beam designating paging queue are formed, the at least one first beam can be determined from the plurality of downlink beams by referring to the identification of the target terminal, the beam scanning paging queue and/or the beam designating paging queue, so as to accurately and quickly determine the at least one first beam from the plurality of downlink beams.

In some embodiments, if the target terminal identifier belongs to at least one candidate terminal identifier in the beam-designated paging queue, determining a candidate terminal identifier matched with the target terminal identifier, determining a beam identifier corresponding to the matched candidate terminal identifier, and determining a downlink beam to which the corresponding beam identifier belongs from a plurality of downlink beams as the first beam.

For example, when a PO is near to transmit, the base station combines the beam scanning paging queue and the beam designating paging queue, determines whether each paging listening occasion requires paging DCI to be transmitted, and the paging message content of the DCI schedule. If a certain beam direction does not need to send a paging message, paging DCI may not be sent at the paging listening occasion corresponding to the beam direction.

The method of constructing the paging message is illustrated in the following three scenarios.

Scene one: beam scanning paging queues { UE1, UE2}, beam assignment paging queues { { { beam 4, UE3}, { beam 5, UE4}, { beam 6, UE4 }.

Scene II: the beam scans the paging queues { UE1, UE2}, the beam designates the paging queue as empty.

Scene III: the beam scan paging queue is empty and the beam designates paging queue { { beam 4, ue3}, { beam 5, ue4}, { beam 6, ue4 }.

For scenario one, the two queues are merged at the beam granularity, as shown in FIG. 9. Fig. 9 is a diagram of paging scheduling in an embodiment of the present disclosure, for scenario three, paging DCI and paging message are sent only on the required beam.

S705: and sending paging downlink control indication DCI at a paging listening occasion corresponding to the beam direction of the first beam.

In this embodiment, the access network device obtains the first information, where the first information is used to indicate a first location notification area of the target terminal, obtains a plurality of downlink beams according to the first location notification area, determines at least one first beam from the plurality of downlink beams, and sends paging downlink control indication DCI at a paging listening occasion corresponding to a beam direction of the first beam. Since at least one first beam is determined from the plurality of downlink beams, and the paging downlink control indication DCI is sent only at the paging listening occasion corresponding to the beam direction of the first beam, the consumption degree of the sending power of the access network device can be effectively reduced, and the PDSCH time-frequency resource can be effectively saved. A beam scanning paging queue and/or a beam designating paging queue are formed in advance, wherein the beam scanning paging queue comprises: at least one candidate terminal identification, the beam-specific paging queue comprising: at least one candidate terminal identity, and a beam identity corresponding to each candidate terminal identity. If the target terminal identification belongs to at least one candidate terminal identification in the beam scanning paging queue, at least one first beam is determined according to the downlink beams, and if the target terminal identification belongs to at least one candidate terminal identification in the beam appointed paging queue, at least one first beam is determined from the downlink beams according to the target terminal identification and the beam appointed paging queue, so that the at least one first beam is rapidly and accurately selected from the downlink beams, and the transmission flexibility of paging downlink control instruction DCI is improved, and the method is effectively applicable to personalized communication scenes.

In the embodiment of the disclosure, a location notification area is provided, which may be represented by a circle with the UE location as the center and the distance D as the radius; multiple beam markers within a cell may also be used. When the UE enters an inactive state, the base station configures a location notification area. After the inactive state UE leaves the location notification area, the location of the inactive state UE may be updated to the base station through a location notification area update procedure. The UE updates its own position to the base station through the position notification area updating flow, and the coarse precision position of the UE can be determined by the base station through the uplink receiving beam direction. Optionally, the UE may report its own positioning information at the same time to assist the base station in obtaining the fine-precision position of the UE.

When the UE inactivity configuration parameter does not need to be changed, the connection release message in the location notification area update procedure may not be sent. The coverage area of the location notification area may be adjusted according to the frequency of the UE generating the location notification area update procedure.

In the embodiment of the disclosure, the base station can determine the downlink beam set available to the UE according to the UE position and the position notification area range and in combination with the downlink beam configuration of the base station, and construct a beam scanning paging queue and a beam designated paging queue. On the basis, the paging DCI monitoring time and paging message content of the PO are determined by integrating all the paging UE information on the PO. The paging DCI and the paging message sending quantity and the paging message length can be reduced, the power consumption of the base station is saved, and the time-frequency resource utilization rate of the base station is improved.
