Description

[0001] This application is a divisional application of the invention patent application with application number 201980000139.7 and invention name “Method, device and storage medium for determining SR configuration” filed on February 14, 2019. Technical Field

[0002] The present disclosure relates to the field of communication technologies, and more particularly to a method, device, and storage medium for determining an SR (Schedule Request) configuration. Background Art

[0003] In the 5G NR (New Radio) system, it is decided to introduce multiple SR configurations, that is, multiple SR configurations can be provided for the terminal, and which SR configuration to use depends on the logical channel that triggers the SR.

[0004] On the Uu interface, the base station sends an RRC (Radio Resource Control) connection reconfiguration message to the terminal, which carries the mapping between logical channels and SR configurations. This message indicates to the terminal the SR configuration corresponding to each logical channel. When the terminal needs to use a logical channel to send data to the base station, if an SR is triggered, the terminal can send an SR to the base station based on the SR configuration corresponding to the logical channel.

[0005] For the logical channels established between terminals for transmitting sidelink data streams, since the mapping relationship between the sidelink data streams and the logical channels is determined by the terminals themselves, the base station cannot obtain the relevant information of the sidelink data streams used to transmit each logical channel, resulting in the base station not being reasonable and accurate when determining the SR configuration of the logical channel.

[0068] Exemplary embodiments will be described in detail herein, with examples illustrated in the accompanying drawings. In the following description, when referring to the drawings, identical numerals in different figures represent identical or similar elements, unless otherwise indicated. The embodiments described in the following exemplary embodiments are not intended to represent all possible embodiments consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present disclosure, as detailed in the appended claims.

[0069] The network architecture and business scenarios described in the embodiments of the present disclosure are intended to more clearly illustrate the technical solutions of the embodiments of the present disclosure, and do not constitute a limitation on the technical solutions provided by the embodiments of the present disclosure. A person skilled in the art will appreciate that, with the evolution of network architecture and the emergence of new business scenarios, the technical solutions provided by the embodiments of the present disclosure are equally applicable to similar technical problems.

[0070] Figure 1 FIG1 is a schematic diagram showing a network architecture according to an exemplary embodiment. The network architecture may include: a core network 11, an access network 12, and a terminal 13.

[0071] The core network 11 includes several core network devices. The functions of the core network devices are mainly to provide user connections, user management, and service carrying, and to provide an interface to the external network as a bearer network. For example, the core network of a 5G NR system may include devices such as an AMF (Access and Mobility Management Function) entity, a UPF (User Plane Function) entity, and an SMF (Session Management Function) entity.

[0072] The access network 12 includes several base stations 14. The access network in the 5G NR system can be called NG-RAN (New Generation-Radio Access Network). The base station 14 is a device deployed in the access network 12 to provide wireless communication functions for the terminal 13. The base station 14 can include various forms of macro base stations, micro base stations, relay stations, access points, etc. In systems using different wireless access technologies, the names of devices with base station functions may be different. For example, in the 5G NR system, they are called gNodeB or gNB. With the evolution of communication technology, the name "base station" may change. For the convenience of description, in the embodiments of the present disclosure, the above-mentioned devices that provide wireless communication functions for the terminal 13 are collectively referred to as base stations.

[0073] There are typically multiple terminals 13, and one or more terminals 13 may be distributed within the cell managed by each base station 14. Terminals 13 may include various handheld devices with wireless communication capabilities, vehicle-mounted devices, wearable devices, computing devices, or other processing devices connected to a wireless modem, as well as various forms of user equipment (UE), mobile stations (MS), terminal devices, and so on. For ease of description, in the embodiments of the present disclosure, the above-mentioned devices are collectively referred to as terminals.

[0074] The base station 14 and the core network device communicate with each other through some air interface technology, such as the NG interface in the 5G NR system. The base station 14 and the terminal 13 communicate with each other through some air interface technology, such as the Uu interface.

[0075] like Figure 2 As shown in the figure, in the 5G NR system, the smallest data transmission granularity within the AS (Access Stratum) is the QoS flow. A QoS flow is the finest QoS differentiation granularity within a PDU (Protocol Data Unit) session. This means that the difference between two PDU sessions lies in their different QoS flows (typically, the TFT (Traffic Flow Template) parameters of the QoS flows). In the 5G NR system, a QoS flow is identified by a QFI (QoS Flow ID), which is used to identify a QoS flow. User plane data with the same QFI within a PDU session receives the same forwarding treatment (e.g., the same scheduling, the same admission threshold, etc.). The QFI must be unique within a PDU session. This means that a PDU session can have multiple (e.g., up to 64) QoS flows, but each QoS flow has a different QFI (ranging from 0 to 63). Therefore, the QFI of two PDU sessions on a terminal may overlap. The QFI can be dynamically configured or equal to the 5-Generation QoS Indicator (5QI). After receiving the QoS flow, the AS needs to complete the mapping of the QoS flow to the logical channel. One or more QoS flows can be mapped to a logical channel. On the Uu interface, this mapping relationship is controlled by the base station.

[0076] In addition, if Figure 3As shown, terminals 13 and 13 (for example, vehicle-mounted equipment and other equipment (such as other vehicle-mounted equipment, mobile phones, RSU (Road Side Unit), etc.)) can communicate with each other through a direct communication interface (such as a PC5 interface). Accordingly, the communication link established based on the direct communication interface can be called a direct link or a side link (sidelink). Compared with communication based on the Uu interface, communication based on the direct communication interface has the characteristics of short delay and low overhead, and is suitable for communication between two terminals with close geographical locations (such as vehicle-mounted equipment and other peripheral devices with close geographical locations). The smallest data transmission granularity on the side link is also a QoS flow. The QoS of the QoS flow on the side link is indicated by VQI (Vehicle QoS Indicator). VQI is a numerical value, and each numerical value indicates the service quality of a set of QoS flows on the side link, including information such as rate, delay, reliability and transmission distance.

[0077] The "5G NR system" in the embodiments of this disclosure may also be referred to as a 5G system or an NR system, but those skilled in the art will understand the meaning. The technical solutions described in the embodiments of this disclosure are applicable to the 5G NR system and to subsequent evolution systems of the 5G NR system.

[0078] In an embodiment of the present disclosure, in response to the technical problems mentioned in the background technology, by providing the QoS parameters of the QoS flow transmitted on the side link to the base station, the base station can reasonably and accurately determine the SR configuration of the logical channel used to transmit the QoS flow based on the QoS parameters of the QoS flow.

[0079] The technical solution of the present disclosure is introduced and explained below through several exemplary embodiments.

[0080] Figure 4 This is a flow chart of a method for determining an SR configuration according to an exemplary embodiment. Figure 1 In the network architecture shown in FIG. , the method may include the following steps ( 401 - 404 ).

[0081] In step 401, the terminal sends sidelink information to the base station, where the sidelink information includes QoS parameters corresponding to a first logical channel used to transmit a first sidelink data flow.

[0082] The first sidelink data stream can be any QoS stream transmitted via the sidelink. In the disclosed embodiment, a mapping relationship exists between the first sidelink data stream and the first logical channel, meaning that the first sidelink data stream is transmitted via the first logical channel. The first logical channel can be any sidelink logical channel. In addition, the mapping relationship between the first sidelink data stream and the first logical channel can be configured by either the terminal or the base station.

[0083] Only one side link data stream, such as the first side link data stream, may be mapped to the first logical channel; alternatively, multiple side link data streams, such as the first side link data stream and at least one other side link data stream, may be mapped to the first logical channel.

[0084] The QoS parameters are used to indicate the QoS requirements of the first side link data flow, such as requirements on rate, delay, reliability, transmission distance, etc. The QoS parameters can be represented by VQI.

[0085] In an embodiment of the present disclosure, side link information is sent to the base station through the terminal. Since the side link information includes the QoS parameters corresponding to the first logical channel, the base station can obtain the QoS requirements of the QoS flow used to transmit the first logical channel.

[0086] In addition, the sidelink information can be sent to the base station through sidelink terminal information (SidelinkUEInformation) or through other messages, which is not limited in the embodiments of the present disclosure.

[0087] In step 402, the base station generates SR configuration information according to the sidelink information, where the SR configuration information is used to indicate the SR configuration of the first logical channel.

[0088] After obtaining the QoS parameters of the first sidelink data flow transmitted on the first logical channel, the base station configures a corresponding SR configuration for the first logical channel according to the QoS parameters. Optionally, the SR configuration includes but is not limited to at least one of the following: an SR prohibition timer, a maximum number of SR transmissions, and a time-frequency resource location that can be used for SR transmission.

[0089] In addition, the base station may explicitly indicate the SR configuration of the first logical channel in the SR configuration information, for example, the SR configuration information includes the correspondence between the identification information of the first logical channel and the SR configuration of the first logical channel; or, the base station may also implicitly indicate the SR configuration of the first logical channel in the SR configuration information, for example, the SR configuration information does not directly include the correspondence between the identification information of the first logical channel and the SR configuration of the first logical channel, but includes other information, and the terminal determines the SR configuration of the first logical channel based on the other information. There are many possible implementation methods for the specific content included in the SR configuration information, and please refer to the description in the following embodiments for details.

[0090] In step 403, the base station sends SR configuration information to the terminal.

[0091] Optionally, the SR configuration information is sent to the terminal via an RRC connection reconfiguration message (RRCConnectionReconfiguration message), or may be sent to the terminal via other messages, which is not limited in the embodiments of the present disclosure.

[0092] In step 404, the terminal determines the SR configuration of the first logical channel according to the SR configuration information.

[0093] After receiving the SR configuration information, the terminal reads the content included in the SR configuration information, and determines the SR configuration of the first logical channel accordingly.

[0094] In addition, when the QoS requirement of the sidelink data flow in the logical channel changes, the terminal can repeat the process of steps 401 to 404 to update the SR configuration of the logical channel to adapt to the new QoS requirement.

[0095] To sum up, in the technical solution provided by the embodiments of the present disclosure, by providing the QoS parameters of the QoS flow transmitted on the side link to the base station, the base station can reasonably and accurately determine the SR configuration of the logical channel used to transmit the QoS flow based on the QoS parameters of the QoS flow.

[0096] Based on Figure 4 In an optional embodiment provided in the embodiment, Figure 5 As shown, the method may include the following steps (501-504).

[0097] In step 501, the terminal sends sidelink information to a base station, where the sidelink information includes a VQI of a first sidelink data stream.

[0098] In this embodiment, the sidelink information includes the VQI of at least one sidelink data stream that the terminal needs to transmit, and the at least one sidelink data stream includes the first sidelink data stream. Optionally, the sidelink information includes the VQIs of all sidelink data streams that the terminal needs to transmit.

[0099] For example, the sidelink data streams that the terminal needs to transmit have four QoS flows, and the identification information (i.e., QFI) of these four QoS flows are 1, 2, 3, and 4. In addition, assuming that the VQIs of these four QoS flows are 1, 2, 3, and 4, respectively, the sidelink information sent by the terminal to the base station includes a VQI list, which contains the VQIs of all QoS flows that the terminal needs to transmit, that is, the VQI list contains four VQIs, 1, 2, 3, and 4.

[0100] In this embodiment, the mapping relationship between sidelink data flows and logical channels is configured by the terminal. For example, the terminal configures QoS flows with QFIs 1 and 2 to be mapped to logical channel 1, QoS flows with QFI 3 to be mapped to logical channel 2, and QoS flows with QFI 4 to be mapped to logical channel 3. In addition, the terminal can map QoS flows with the same or similar QoS requirements to the same logical channel.

[0101] In a possible implementation, the terminal first completes mapping of the sidelink data stream to the logical channel, and then sends the sidelink terminal information to the base station, which carries the VQIs of the sidelink data streams in all logical channels.

[0102] In step 502, the base station generates SR configuration information according to the sidelink information, where the SR configuration information includes a correspondence between the VQI of the first sidelink data flow and the SR configuration.

[0103] After receiving the sidelink information, the base station configures a corresponding SR configuration for each VQI in the VQI list according to the VQI list included in the sidelink information. In the embodiments of the present disclosure, the specific manner in which the base station configures the corresponding SR configuration for the VQI is not limited. For example, the base station can configure different SR configurations for different VQIs, or can configure the same SR configuration for multiple VQIs (such as similar VQIs). This embodiment of the present disclosure does not limit this.

[0104] In step 503, the base station sends SR configuration information to the terminal.

[0105] Optionally, the base station sends an RRC connection reconfiguration message to the terminal, which carries at least one group of SR configurations, and each group of SR configurations corresponds to a VQI list.

[0106] Exemplarily, the RRC connection reconfiguration message carries SR parameter A, SR parameter B and SR parameter C, where the VQI corresponding to SR parameter A is 1, the VQI corresponding to SR parameter B is 2, and the VQI corresponding to SR parameter C is 3 and 4.

[0107] In step 504, the terminal determines the SR configuration of the first logical channel according to the SR configuration information.

[0108] After receiving the SR configuration information, the terminal determines the SR configuration corresponding to the VQI of the first sidelink data flow as the SR configuration of the first logical channel based on the correspondence between the VQI of the first sidelink data flow and the SR configuration, as well as the mapping relationship between the first sidelink data flow and the first logical channel, contained in the SR configuration information. In the above example, since a QoS flow with a QFI of 3 is mapped to logical channel 2, and the VQI corresponding to the QoS flow with a QFI of 3 is 3, corresponding to SR parameter C, the terminal sets the SR parameter corresponding to logical channel 2 to C.

[0109] Optionally, if the first logical channel is used to transmit at least one other sidelink data stream in addition to the first sidelink data stream, the terminal selects the SR configuration corresponding to the maximum VQI as the SR configuration for the first logical channel based on the correspondence between the VQI and the SR configuration of the first sidelink data stream, as well as the correspondence between the VQI and the SR configuration of the other sidelink data streams, included in the SR configuration information. In the above example, since QoS flows with QFIs 1 and 2 are mapped to logical channel 1, and the QoS flow with QFI 1 corresponds to a VQI of 1, corresponding to SR parameter A, and the QoS flow with QFI 2 corresponds to a VQI of 2, corresponding to SR parameter B, the terminal selects the SR configuration corresponding to the maximum VQI, i.e., SR parameter B corresponding to VQI 2, as the SR configuration for logical channel 1. In this manner, when a logical channel is mapped to multiple QoS flows with different QoS requirements, selecting the SR configuration corresponding to the maximum VQI as the SR configuration for the logical channel can meet the highest QoS requirement and ensure the reliability of the SR configuration for the logical channel.

[0110] In addition, when the QoS requirement of the sidelink data flow in the logical channel changes, the terminal can repeat the process of steps 501 to 504 to update the SR configuration of the logical channel to adapt to the new QoS requirement.

[0111] Based on Figure 4 In another optional embodiment provided by the embodiment, as Figure 6 As shown, the method may include the following steps (601-604).

[0112] In step 601, the terminal sends sidelink information to the base station, where the sidelink information includes a correspondence between identification information of a first logical channel and a VQI of a first sidelink data flow.

[0113] In this embodiment, the sidelink information includes the correspondence between VQIs and logical channels. For example, the sidelink information includes identification information of at least one logical channel created by the terminal for transmitting a sidelink data stream, where the at least one logical channel includes a first logical channel. Furthermore, the sidelink information also includes the VQI corresponding to each logical channel, i.e., the VQI of the sidelink data stream mapped to each logical channel.

[0114] For example, the terminal needs to transmit four QoS flows for the sidelink data stream, and the identification information (i.e., QFI) of these four QoS flows is 1, 2, 3, and 4, respectively. Furthermore, it is assumed that the VQIs of these four QoS flows are 1, 2, 3, and 4, respectively. In this embodiment, the mapping relationship between the sidelink data stream and the logical channel is configured by the terminal. For example, the terminal configures the QoS flows with QFIs 1 and 2 to be mapped to logical channel 1, the QoS flow with QFI 3 to be mapped to logical channel 2, and the QoS flow with QFI 4 to be mapped to logical channel 3. In addition, the terminal can map QoS flows with the same or similar QoS requirements to the same logical channel. In this way, the sidelink information sent by the terminal to the base station includes the correspondence between logical channel 1 and VQIs 1 and 2, the correspondence between logical channel 2 and VQI 3, and the correspondence between logical channel 3 and VQI 4.

[0115] In step 602, the base station generates SR configuration information according to the side link information, where the SR configuration information includes a correspondence between identification information of the first logical channel and the SR configuration of the first logical channel.

[0116] After receiving the side link information, the base station configures the corresponding SR configuration for each logical channel according to the correspondence between the logical channel and the VQI contained in the side link information. In the embodiment of the present disclosure, the specific manner in which the base station configures the corresponding SR configuration for the logical channel is not limited. For example, when a certain logical channel corresponds to multiple VQIs, the base station determines the SR configuration of the logical channel according to the maximum VQI value among the multiple VQIs, thereby meeting the highest QoS requirements and ensuring the reliability of the SR configuration of the logical channel. In addition, the base station can configure different SR configurations for different logical channels, or configure the same SR configuration for different logical channels, which is not limited in the embodiment of the present disclosure.

[0117] Still combining with the above example, the SR configuration information generated by the base station may include: the correspondence between logical channel 1 and SR parameter B, and the correspondence between logical channels 2 and 3 and SR parameter C.

[0118] In step 603, the base station sends SR configuration information to the terminal.

[0119] The SR configuration information may be sent to the terminal via an RRC connection reconfiguration message, or may be sent to the terminal via other messages, which is not limited in the embodiments of the present disclosure.

[0120] In step 604, the terminal determines the SR configuration of the first logical channel according to the SR configuration information.

[0121] After receiving the SR configuration information, the terminal reads the correspondence between the logical channels and the SR configurations contained in the SR configuration information, thereby determining the SR configuration of each logical channel.

[0122] Still referring to the above example, the terminal sets the SR parameter corresponding to logical channel 1 to B, and sets the SR parameters corresponding to logical channels 2 and 3 to C.

[0123] In addition, when the QoS requirement of the sidelink data flow in the logical channel changes, the terminal can repeat the process of steps 601 to 604 to update the SR configuration of the logical channel to adapt to the new QoS requirement.

[0124] Based on Figure 4 In another optional embodiment provided by the embodiment, as Figure 7 As shown, the method may include the following steps (701-704).

[0125] In step 701, the terminal sends sidelink information to the base station, where the sidelink information includes a correspondence between identification information of a first sidelink data flow and a VQI of the first sidelink data flow.

[0126] In this embodiment, the sidelink information includes a correspondence between sidelink data streams and VQIs. For example, the sidelink information includes a correspondence between identification information of at least one sidelink data stream that the terminal needs to transmit and the VQI, where the at least one sidelink data stream includes a first sidelink data stream. Alternatively, the sidelink information includes a correspondence between identification information of all sidelink data streams that the terminal needs to transmit and the VQIs.

[0127] For example, the side link data stream that the terminal needs to transmit has four QoS streams, and the identification information (i.e., QFI) of these four QoS streams are 1, 2, 3, and 4, respectively. The side link information sent by the terminal to the base station includes a QFI list, which contains the QFIs of all QoS streams that the terminal needs to transmit, that is, the QFI list contains four QFIs, 1, 2, 3, and 4; and the terminal indicates in the side link information that the VQIs corresponding to the above four QFIs are 1, 2, 3, and 4, respectively.

[0128] In step 702, the base station generates SR configuration information based on the side link information, where the SR configuration information includes the correspondence between the identification information of the first side link data stream and the identification information of the first logical channel, and the correspondence between the identification information of the first logical channel and the SR configuration of the first logical channel.

[0129] In this embodiment, the mapping relationship between sidelink data flows and logical channels is configured by the base station. For example, the base station maps QoS flows with QFIs 1 and 2 to logical channel 1, QoS flows with QFI 3 to logical channel 2, and QoS flows with QFI 4 to logical channel 3. Furthermore, the base station can map QoS flows with the same or similar QoS requirements to the same logical channel.

[0130] In addition, after the base station completes the configuration of the mapping relationship between the side link data stream and the logical channel, it configures the corresponding SR configuration for each logical channel according to the QoS requirements of the side link data stream corresponding to each logical channel. In the embodiment of the present disclosure, the specific method of configuring the corresponding SR configuration for the logical channel by the base station is not limited. For example, when a certain logical channel corresponds to multiple VQIs, the base station determines the SR configuration of the logical channel according to the maximum value of the VQI among the multiple VQIs, thereby meeting the highest QoS requirements and ensuring the reliability of the SR configuration of the logical channel. In addition, the base station can configure different SR configurations for different logical channels, or configure the same SR configuration for different logical channels. The embodiment of the present disclosure does not limit this.

[0131] Still combining with the above example, the SR configuration information generated by the base station may include: the correspondence between QFI 1 and QFI 2 and logical channel 1, the correspondence between QFI 3 and logical channel 2, and the correspondence between QFI 4 and logical channel 3; in addition, the SR configuration information also includes the correspondence between logical channel 1 and SR parameter B, and the correspondence between logical channels 2 and 3 and SR parameter C.

[0132] In step 703, the base station sends SR configuration information to the terminal.

[0133] The SR configuration information may be sent to the terminal via an RRC connection reconfiguration message, or may be sent to the terminal via other messages, which is not limited in the embodiments of the present disclosure.

[0134] In step 704, the terminal determines the SR configuration of the first logical channel according to the SR configuration information.

[0135] After receiving the SR configuration information, the terminal reads the correspondence between the side link data stream and the logical channel, as well as the correspondence between the logical channel and the SR configuration contained in the SR configuration information, so as to complete the mapping between the side link data stream and the logical channel, and determine the SR configuration of each logical channel.

[0136] Still referring to the above example, the terminal maps the QoS flows with QFIs 1 and 2 to logical channel 1, the QoS flow with QFI 3 to logical channel 2, and the QoS flow with QFI 4 to logical channel 3. In addition, the terminal sets the SR parameter corresponding to logical channel 1 to B, and sets the SR parameters corresponding to logical channels 2 and 3 to C.

[0137] In addition, when the QoS requirement of the sidelink data flow in the logical channel changes, the terminal can repeat the process of steps 701 to 704 to update the SR configuration of the logical channel to adapt to the new QoS requirement.

[0138] In the above Figure 5 、 Figure 6 and Figure 7 The embodiments provide three different implementations for configuring SR configurations for sidelink logical channels. All three implementations can provide the base station with the QoS parameters of the QoS flow transmitted on the sidelink, enabling the base station to reasonably and accurately determine the SR configuration of the logical channel used to transmit the QoS flow based on the QoS parameters of the QoS flow. In these three implementations, the control capability of the base station is gradually improved, and the signaling exchanged between the terminal and the base station will also increase accordingly. In actual applications, the appropriate implementation method can be selected based on actual needs.

[0177] Figure 10 The figure is a schematic structural diagram of a terminal according to an exemplary embodiment.

[0178] The terminal 1000 includes a transmitter 1001, a receiver 1002 and a processor 1003. The processor 1003 may also be a controller. Figure 10 denoted as “controller / processor 1003 ”. Optionally, the terminal 1000 may further include a modem processor 1005 , wherein the modem processor 1005 may include an encoder 1006 , a modulator 1007 , a decoder 1008 and a demodulator 1009 .

[0179] In one example, transmitter 1001 conditions (e.g., performs analog-to-analog conversion, filtering, amplification, and frequency upconversion) the output samples and generates an uplink signal, which is transmitted to a base station via an antenna. On the downlink, the antenna receives the downlink signal transmitted by the base station. Receiver 1002 conditions (e.g., performs filtering, amplification, frequency downconversion, and digitization) the signal received from the antenna and provides input samples. Within modem processor 1005, encoder 1006 receives traffic data and signaling messages to be transmitted on the uplink and processes them (e.g., formats, encodes, and interleaves them). Modulator 1007 further processes (e.g., performs symbol mapping and modulation) the encoded traffic data and signaling messages and provides output samples. Demodulator 1009 processes (e.g., demodulates) the input samples and provides symbol estimates. Decoder 1008 processes (e.g., deinterleaves and decodes) the symbol estimates and provides decoded data and signaling messages for transmission to terminal 1000. The encoder 1006, modulator 1007, demodulator 1009, and decoder 1008 can be implemented by the combined modem processor 1005. These units perform processing according to the radio access technology adopted by the radio access network (for example, the access technology of 5G NR and other evolved systems). It should be noted that when the terminal 1000 does not include the modem processor 1005, the above functions of the modem processor 1005 can also be completed by the processor 1003.

[0180] The processor 1003 controls and manages the actions of the terminal 1000, and is used to execute the processing performed by the terminal 1000 in the above-mentioned embodiments of the present disclosure. For example, the processor 1003 is also used to execute the various steps on the terminal side in the above-mentioned method embodiments, and / or other steps of the technical solutions described in the embodiments of the present disclosure.

The transmitter / receiver 1101 is used to support the transmission and reception of information between the base station and the terminal in the above embodiment, and to support communication between the base station and other network entities. The processor 1102 performs various functions for communicating with the terminal. In the uplink, the uplink signal from the terminal is received via the antenna, demodulated by the receiver 1101 (for example, the high-frequency signal is demodulated into a baseband signal), and further processed by the processor 1102 to recover the service data and signaling information sent by the terminal. In the downlink, the service data and signaling message are processed by the processor 1102, and modulated by the transmitter 1101 (for example, the baseband signal is modulated into a high-frequency signal) to generate a downlink signal, which is transmitted to the terminal via the antenna. It should be noted that the above demodulation or modulation functions can also be performed by the processor 1102. For example, the processor 1102 is also used to execute the various steps on the base station side in the above method embodiment, and / or other steps of the technical solution described in the embodiment of the present disclosure.

[0185] Furthermore, the base station 1100 may also include a memory 1103, which is used to store program codes and data of the base station 1100. In addition, the base station may also include a communication unit 1104. The communication unit 1104 is used to support the base station to communicate with other network entities (such as network equipment in the core network). For example, in the 5G NR system, the communication unit 1104 can be an NG-U interface, which is used to support the base station to communicate with the UPF (User Plane Function) entity; or, the communication unit 1104 can also be an NG-C interface, which is used to support access to the AMF (Access and Mobility Management Function) entity for communication.

[0186] It is understandable that Figure 11 Only a simplified design of the base station 1100 is shown. In practical applications, the base station 1100 may include any number of transmitters, receivers, processors, controllers, memories, communication units, etc., and all base stations that can implement the embodiments of the present disclosure are within the scope of protection of the embodiments of the present disclosure.
