Provided that the same technical effects are achieved, the base station is not limited to specific technical vocabulary. It should be noted that in the embodiments of this application, a base station in the NR system is merely used as an example, but does not limit a specific type of the base station. 
     With reference to the accompanying drawings, the following describes in detail a method and an apparatus for sending auxiliary information, a method and an apparatus for receiving auxiliary information, a terminal, and a network side device in the embodiments of this application based on specific embodiments and application scenarios thereof. 
       FIG.  2    is a flowchart of a method for sending auxiliary information according to an embodiment of this application. As shown in  FIG.  2   , the method for sending auxiliary information is applied to a terminal and includes the following steps: 
     Step  201 : Send auxiliary information for a target configuration to a network side device, where the target configuration is a configuration related to transmission of a preconfigured physical uplink shared channel PUSCH resource. 
     In this embodiment of this application, the target configuration may be understood as a configuration related to transmission of an uplink resource preconfigured by the network side device. Alternatively, the target configuration may be a configuration related to transmission of a preconfigured physical uplink shared channel (PUSCH) resource. For example, the target configuration may be similar to PUR-Config in LTE. For another example, the target configuration may be a configuration related to a transmission mode of a preconfigured PUSCH resource for small data transmission (SDT) in NR. In addition to the above target configuration, there may be another target configuration. This is not limited in this embodiment of this application. 
     The following briefly describes an NR SDT data service. 
     The NR SDT data service may be understood as a service of small and infrequent data. For example, an NR SDT data service in an application of a smartphone may include data of an instant messaging service, heart-beat/keep-alive data of an instant messaging (IM)/email client and another application, push notifications of various applications, and the like. For another example, an NR SDT data service in an application of a dumbphone may include periodic positioning messages of a wearable device, data of a sensor, data of a smart water meter, and the like. The NR SDT data service may alternatively be sporadic low-throughput short data and the like. 
     In this embodiment of this application, the terminal sends the auxiliary information to the network side device, so that the network side device can configure an uplink resource according to the auxiliary information. Therefore, the auxiliary information can assist the network side device in better configuring the uplink resource, thereby enabling the uplink resource configured by the network side device to better satisfy a demand of the terminal. 
     Optionally, before the sending auxiliary information for a target configuration to a network side device, the method further includes:
     receiving configuration information sent by the network side device, where the configuration information is used to indicate whether the terminal is allowed to report the auxiliary information; and   the auxiliary information is sent in a case that the configuration information indicates that the terminal is allowed to report the auxiliary information.   

     In this embodiment of this application, the network side device may send the configuration information to the terminal. The configuration information may be used to indicate whether the terminal is allowed to report the auxiliary information. In this way, in a case that the terminal receives the configuration information sent by the network side device and used to indicate that the terminal is allowed to report the auxiliary information, the terminal can send the auxiliary information to the network side device on an appropriate occasion. However, if the terminal receives the configuration information sent by the network side device and used to indicate that the terminal is not allowed to report the auxiliary information, the terminal may not send the auxiliary information to the network side device. 
     It should be noted that the above configuration information may directly indicate whether the terminal is allowed to report the auxiliary information, or indirectly indicate whether the terminal is allowed to report the auxiliary information. 
     Optionally, the configuration information includes a target bit, where the target bit is used to indicate whether the terminal is allowed to report the auxiliary information; and/or 
     the configuration information includes information about a target timer, where the target timer is configured to indicate whether the terminal is allowed to report the auxiliary information. 
     The target bit may be one bit, and may directly indicate whether the terminal is allowed to report the auxiliary information, or indirectly indicate whether the terminal is allowed to report the auxiliary information. The target timer may be one timer, and may directly indicate whether the terminal is allowed to report the auxiliary information. 
     Optionally, the sending auxiliary information for a target configuration to a network side device includes: 
     sending the auxiliary information for the target configuration to the network side device in a case that an initiation condition is satisfied. 
     Optionally, the initiation condition includes at least one of the following:
     the network side device allows the terminal to send the auxiliary information;   the terminal is interested in the target configuration;   the terminal is not interested in the target configuration;   the terminal is no longer interested in the target configuration;   the terminal is interested in a first transmission mode, where the first transmission mode is a transmission mode related to the target configuration;   the terminal is not interested in the first transmission mode;   the terminal is no longer interested in the first transmission mode;   the target configuration does not match a service feature of the terminal;   a medium access control (MAC) protocol data unit (PDU) of uplink data is less than or equal to a transport block size (TBS) configured based on a type of the terminal; and   a state of the terminal is a target state, where the target state is a radio resource control (RRC) connected state or a non-RRC connected state, or the target state is only the RRC connected state, or the target state is only the non-RRC connected state.   

     The first transmission mode is a transmission mode related to the target configuration. For example, the first transmission mode may be an LTE PUR transmission mode; or may be a transmission mode of a preconfigured PUSCH resource for SDT in NR. This is not limited in this embodiment of this application. 
     In the above initiation condition, that the target configuration does not match a service feature of the terminal may be understood as follows: At least one configuration in the target configuration does not match the service feature of the terminal. In other words, that the target configuration does not match a service feature of the terminal may include the following two cases: Some configurations in the target configuration do not match the service feature of the terminal; and all configurations in the target configuration do not match the service feature of the terminal. 
     In the above initiation condition, the target state in which the terminal reports the auxiliary information may be preconfigured by the network side device, or may be specified in a protocol. If the target state is merely the RRC connected state, the terminal may report the auxiliary information to the network side device only when in the RRC connected state, but cannot report the auxiliary information to the network side device when in the non-RRC connected state. If the target state is merely the non-RRC connected state, the terminal may report the auxiliary information to the network side device only when in the non-RRC connected state, but cannot report the auxiliary information to the network side device when in the RRC connected state. If the target state is the RRC connected state or the non-RRC connected state, the terminal may report the auxiliary information to the network side device when in either the RRC connected state or the non-RRC connected state. 
     As an example, the initiation condition may be that the terminal is interested in a configuration of the preconfigured PUSCH resource, or that the terminal is interested in a transmission mode of the preconfigured PUSCH resource. As another example, the initiation condition may be that the terminal is not interested in or is no longer interested in a configuration of the preconfigured PUSCH resource, or that the terminal is not interested in or is no longer interested in a transmission mode of the preconfigured PUSCH resource for SDT. As still another example, the initiation condition may be that a configuration of an existing preconfigured PUSCH resource does not match or is not suitable for a service of the terminal, that is, at least one configuration in the target configuration does not match the service feature of the terminal. 
     Optionally, the auxiliary information includes first auxiliary information and/or second auxiliary information in a case that the terminal needs the target configuration. The first auxiliary information is used to indicate a tendentious configuration of the terminal for the target configuration, and the second auxiliary information is used to indicate service status of the terminal. 
     In this implementation, that the terminal needs the target configuration may include a case that the terminal actively needs the target configuration. For example, the terminal is interested in the target configuration. For another example, the terminal is interested in the transmission mode (namely, the first transmission mode) related to the target configuration. Alternatively, the terminal may passively need or be forced to need the target configuration. In other words, the network side device considers that the terminal needs the target configuration. For example, the terminal is not interested in the target configuration or the transmission mode related to the target configuration, but the network side device considers that the terminal needs the target configuration. 
     Both the first auxiliary information and the second auxiliary information may be understood as content of the auxiliary information. When the terminal initiates reporting of the auxiliary information, the content of the auxiliary information may be specified through an RRC layer of the terminal, and then the auxiliary information may be submitted to an underlying protocol entity for transmission. 
     In this implementation, the first auxiliary information is used to indicate the tendentious configuration (or referred to as a preferred configuration) of the terminal for the target configuration. The tendentious configuration may be understood as a result of the target configuration. In other words, the terminal expects the network side device to configure the target configuration according to the tendentious configuration, and enables, by sending the first auxiliary information to the network side device, the network side device to be aware of the terminal’s tendentious configuration for the target configuration. Therefore, the network side device is enabled to configure the target configuration according to the first auxiliary information. 
     The second auxiliary information is used to indicate the service status of the terminal. The network side device is enabled to be aware of the service status of the terminal after the second auxiliary information is sent to the network side device, so that the network side device can reasonably configure the target configuration according to the service status of the terminal. 
     A quantity of pieces of each of the first auxiliary information and the second auxiliary information may be one or more. 
     Specific content of the first auxiliary information and the second auxiliary information is described below respectively. 
     Optionally, the first auxiliary information includes at least one of a target configuration identifier, a service identifier, a service pattern identifier, a configuration parameter, and first transmission bearer information. 
     This embodiment provides the content of the first auxiliary information. 
     The target configuration identifier may be, for example, PUSCH configuration 1. 
     The service identifier may be, for example, service 1. 
     The service pattern identifier may be, for example, traffic pattern 1. 
     It should be noted that both the service identifier and the service pattern identifier are used to indicate a specific service type or service pattern, and have the same or similar meanings. Therefore, the first auxiliary information may include both the service identifier and the service pattern identifier, or only any one of the service identifier and the service pattern identifier. 
     Optionally, the configuration parameter includes at least one of a TBS, a quantity of PUSCH occasions (PUSCH occasions), a period of a PUSCH occasion, time offset for the first PUSCH occasion, a bandwidth part (BWP) identifier, and a quantity of hybrid automatic repeat requests (HARQ). 
     The unit of the period of the PUSCH occasion may be any case. The unit of the time offset for the first PUSCH occasion (time offset for the first PUSCH occasion) may also be any case. The BWP identifier may be, for example, activated BWP 1. 
     Optionally, the first transmission bearer information includes at least one of a radio bearer identifier, a logical channel identifier, a data flow identifier, a session identifier, and a cell group identifier. 
     The radio bearer identifier may be, for example, data radio bearer 1 (Data Radio bearer 1, DRB1). The logical channel identifier may be, for example, logical channel identifier 1 (Logical Channel ID 1, LCID 1). The data flow identifier may be, for example, QoS flow 1. The session identifier may be, for example, PDU session 1. The cell group identifier may be, for example, master cell group (MCG) or secondary cell group (SCG). 
     Optionally, the second auxiliary information includes at least one of Quality of Service (Quality of Service, QoS) requirement information and service status information. 
     A quantity of pieces of each of the QoS requirement information and the service status information may be one or more. 
     Optionally, the QoS requirement information includes at least one of a service identifier, a service pattern identifier, QoS description information, and second transmission bearer information; and 
     the second transmission bearer information is used to indirectly indicate a QoS requirement of the terminal. 
     The service identifier may be, for example, service identifier (identifier, ID) 1. The service pattern identifier may be, for example, traffic pattern 1. The QoS description information (QoS profile) may be, for example, description information such as low delay and high reliability. 
     Optionally, the second transmission bearer information includes at least one of a radio bearer identifier, a data flow identifier, a session identifier, and a logical channel identifier. 
     The radio bearer identifier may be, for example, data radio bearer 1 (Data Radio bearer 1, DRB1). The data flow identifier may be, for example, QoS flow 1. The session identifier may be, for example, PDU session 1. The logical channel identifier may be, for example, logical channel identifier 1 (Logical Channel ID 1, LCID 1). 
     Optionally, the service status information includes at least one of a service identifier, a service pattern identifier, a service period (periodicity), a service starting time, a service ending time, a service duration time, and a service size (packet size). 
     The service identifier may be, for example, service ID 1. The service pattern identifier may be, for example, traffic pattern 1. The service period (or a period of the service pattern) may be any value and any time unit, for example, 5 hours. 
     A quantity of the service starting time (or a starting time of the service pattern) may be one or more. A quantity of the service ending time (or an ending time of the service pattern) may also be one or more. A quantity of the service duration time (or a duration time of the service pattern) may also be one or more. A quantity of the service size (or a size of the service pattern) may also be one or more. 
     Optionally, a quantity of each of the service starting time, the service ending time, the service duration time, and the service size is one or more. 
     When the quantity of the service starting time is a complex number, the quantity of the service ending time and/or the service duration time is also a complex number, and a mapping relationship between the service starting time and the service ending time and/or the service duration time is required. For example, service starting time 1 corresponds to service ending time 1 and/or service duration time 1, and service starting time 2 corresponds to service ending time 2 and/or service duration time 2. 
     A time value of the service starting time may be represented in at least one of the following manners: 
     The time value of the service starting time is represented by an absolute time, for example, 14:00 China Standard Time (CST). 
     The time value of the service starting time is represented by a relative time, and a reference time thereof may be any time, for example, 00:00 CST. 
     When the quantity of the service ending time is a complex number, the quantity of the service starting time and/or the service duration time is also a complex number, and a mapping relationship between the service ending time and the service starting time and/or the service duration time is required. For example, service ending time 1 corresponds to service starting time 1 and/or service duration time 1, and service ending time 2 corresponds to service starting time 2 and/or service duration time 2. 
     A time value of the service ending time may be represented in at least one of the following manners: 
     The time value of the service ending time is represented by an absolute time, for example, 14:00 CST. 
     The time value of the service ending time is represented by a relative time, and a reference time thereof may be any time, for example, 00:00 CST, or a corresponding service starting time. 
     When the quantity of the service duration time is a complex number, the quantity of the service starting time and/or the service ending time is also a complex number, and a mapping relationship between the service duration time and the service starting time and/or the service ending time is required. For example, service duration time 1 corresponds to service starting time 1 and/or service ending time 1, and service duration time 2 corresponds to service starting time 2 and/or service ending time 2. 
     A value of the service duration time may be any value and any time unit, for example, 5 minutes. 
     A value of the service size may be any value, and a unit of the service size may be any unit. For example, the service size is 800 bits. 
     The above describes the specific content of the first auxiliary information and the second auxiliary information. Because the auxiliary information includes the above content, for example, the auxiliary information includes content such as the terminal’s tendentious configuration for the target configuration, QoS requirement information, service status information, and the like, the network side device can be assisted in better configuring the target resource. 
     Optionally, the auxiliary information includes third auxiliary information in a case that the terminal does not need the target configuration, and the third auxiliary information is used to indicate that the target configuration needs to be released. 
     The third auxiliary information may be an identifier used to indicate that an identifier configured for the preconfigured PUSCH resource needs to be released, for example, may be pur-ReleaseRequest. 
     In a case that the terminal does not need the target configuration, the terminal can enable, by sending the third auxiliary information to the network side device, the network side device to be aware that the terminal does not need the target configuration. Therefore, the network side device does not need to configure the target configuration for the terminal, thereby reducing resource overheads of the network side device in configuring the target configuration. 
     As an example, two specific embodiments are provided below by taking the target configuration as a configuration related to the transmission of preconfigured PUSCH resource. 
     EMBODIMENT I 
     As shown in  FIG.  3   , the service pattern of the terminal is burstdata (several data packets are sent at one time, and each interval between the data packets is very short).  FIG.  3    shows that three data packets are sent at one time. These three packets are St1-Et1, St2-Et2, and St3-Et3 respectively. 
     The network side device uses one bit (bit) in system information to indicate that the terminal is allowed to report the auxiliary information. In a case that the initiation condition of the auxiliary information is satisfied (for example, the terminal is interested in the configuration of the preconfigured PUSCH resource), the terminal sends the auxiliary information to the network side device. 
     The content of the auxiliary information includes the tendentious configuration related to the configuration of the preconfigured PUSCH resource, the QoS requirement information, and the service status information.

     A quantity of the starting time of the service pattern is 3, namely, St1=09:00, St2=09:02, and St3=09:04. 
     A quantity of the ending time of the service pattern is 3, namely, Et1=09:01, Et2=09:03, and Et3=09:06. 
     A quantity of the size of the service pattern is three. Packet 1 is 20 bits (corresponding to St1 and Et1), Packet 2 is 20 bits (corresponds to St2 and Et2), and Packet 3 is 40 bits (corresponds to St3 and Et3). 
     EMBODIMENT II 
     As shown in  FIG.  4   , when the service pattern of the terminal changes, the configuration of the preconfigured PUSCH resource needs to be updated. 
     The network side device uses one timer to indicate that the terminal is allowed to report the auxiliary information. In a case that the initiation condition of the auxiliary information is satisfied (for example, the terminal is interested in the transmission mode of the preconfigured PUSCH resource), the terminal sends the auxiliary information to the network side device. 
     The content of the auxiliary information includes the tendentious configuration related to the configuration of the preconfigured PUSCH resource, the QoS requirement information, and the service status information.

     It may be clearly understood by a person skilled in the art that, for convenience and brevity of description, for a specific working process of the above described system, apparatus, and unit, reference may be made to a corresponding process in the above method embodiments, and details are not described herein again. 
     In the embodiments provided in this application, it should be understood that the disclosed apparatus and method may be implemented in another manner. For example, the described apparatus embodiment is merely an example. For example, the unit division is merely logical function division. In actual implementation, there may be another division manner. For example, multiple units or components may be combined or integrated into another system, or some features may be ignored or not performed. In addition, the displayed or discussed mutual couplings or direct couplings or communication connections may be implemented through some interfaces. The indirect couplings or communication connections between the apparatuses or units may be implemented in electronic, mechanical, or other forms. 
     The units described as separate parts may or may not be physically separate, and parts displayed as units may or may not be physical units, may be located in one place, or may be distributed on multiple network units. Some or all of the units may be selected based on an actual requirement to implement the objectives of the solutions in the embodiments. 
     In addition, functional units in the embodiments of the present disclosure may be integrated into one processing unit, or each of the units may exist alone physically, or two or more units are integrated into one unit. 
     Based on the descriptions of the above implementations, a person skilled in the art may clearly understand that the method in the above embodiment may be implemented by software in addition to a necessary universal hardware platform or by hardware only. In most circumstances, the former is a preferred implementation. Based on such understanding, the technical solutions of this application essentially, or the part contributing to the prior art may be implemented in a form of a software product. The computer software product is stored in a storage medium (for example, a ROM/RAM, a magnetic disk, or a compact disc), and includes several instructions for instructing a terminal (which may be a mobile phone, a computer, a server, an air conditioner, a network device, or the like) to perform the method described in the embodiments of this application. 
     It can be understood that the embodiments described in the present disclosure may be implemented by hardware, software, firmware, middleware, microcode, or a combination thereof. For implementation with hardware, the module, unit, and subunit can be implemented in one or more application specific integrated circuits (ASIC), a digital signal processor (DSP), a DSP device (DSPD), a programmable logic device (PLD), a field-programmable gate array (FPGA), a general-purpose processor, a controller, a micro-controller, a micro-processor, and other electronic units for implementing the functions of the present disclosure, or a combination thereof. 
     For implementation with software, technologies described in the embodiments of the present disclosure may be implemented by executing functional modules (for example, a process and a function) in the embodiments of the present disclosure. A software code may be stored in the memory and executed by the processor. The memory may be implemented in the processor or outside the processor. 
     The embodiments of this application are described above with reference to the accompanying drawings, but this application is not limited to the above specific implementations. The above specific implementations are merely schematic instead of restrictive. Under enlightenment of this application, a person of ordinary skills in the art may make many forms without departing from aims and the protection scope of claims of this application, all of which fall within the protection scope of this application.
