The amount of data to be transmitted by the emergency service is small each time, but it must be quickly transmitted. The short transmission time is an important feature of emergency services.

The non-emergency services involved in the existing communication system, for example, Mobile Broadband (MBB) services, the minimum data packet also needs to occupy one Transmission Time Interval (TTI) in the time domain, that is, The minimum allocation granularity of the resources used to transmit non-emergency services in the time domain is the TTI. In the prior art, when a user equipment (User Equipment, UE) sends a non-emergency service to a base station, the user equipment needs to send a scheduling request (SR) to the base station, and waits for the base station to schedule the service data. The method for transmitting the uplink service of the prior art is inefficient. If the uplink emergency service is transmitted by using the prior art, the transmission of the uplink emergency service may be delayed, so that the base station cannot process the uplink emergency service in time.

The UE is a user terminal in a 3G and 4G network, which is equivalent to a mobile station (Mobile Station, MS) in a 2G network, and may include a wireless terminal such as a mobile phone or a tablet (with a SIM card), or may be a machine-to-machine ( M2M, Machine to Machine) Wireless terminals in communication, such as sensors, meters capable of remote meter reading, and other mobile communication devices.

The overall concept of the uplink emergency service sending method provided by the present invention is first described below, and the implementation method of the method in the specific communication system, such as LTE (4G) and GSM (2G), will be described in detail later.

First, the overall concept of the uplink emergency service sending method provided by the present invention is described in conjunction with FIG. 2: the base station reserves resources for uplink emergency services. That is to say, the resources reserved by the base station are not occupied by non-emergency services. The resources involved in the embodiments of the present invention may be time-frequency resources (such as RBs or REs) in the LTE system, or may be time slot resources in the GSM system. In an actual application, the reserved resource may also be other types of air interface resources, which are not limited herein.

Referring to FIG. 2, the transmission method of the uplink emergency service shown in FIG. 2 may include:

S101. The base station reserves reserved resources for transmitting uplink emergency services from the system resources.

S103. The base station sends the first indication information to the UE, where the UE sends the uplink emergency service by using the resource indicated by the first indication information, that is, the reserved resource. Here, the first indication information is used to indicate which resources the reserved resource is. Correspondingly, the UE receives the first indication information sent by the base station.

S105. The UE receives an instruction to send an uplink emergency service to the base station. Specifically, the instruction may be generated by the internal trigger of the UE, or may be received from the outside, and is not limited herein.

S107. In response to the instruction received in S105, the UE may send the uplink emergency service by using the resource indicated by the first indication information, that is, the reserved resource, according to the first indication information. Correspondingly, the base station may receive the uplink emergency service by using the reserved resource.

Specifically, the base station may send the first indication information to the UE by using the following two methods, that is, notifying the UE by using the reserved resource: 1. The base station sends the radio resource control (RRC) message to the UE by using a radio resource control (RRC) message. The first indication information is applicable to the static configuration of the reserved resource by the base station, that is, the scenario in which the reserved resource does not change in a long time; 2. the base station passes the physical control channel (PDCCH) or The physical broadcast channel (PBCH) transmits the first indication information to the UE, and, like the control information of the next non-emergency service, the first indication information may also be distributed and transmitted in frequency and time to obtain a diversity gain, The method enables the base station to re-select the resources reserved for the emergency service from the system resources according to the scheduling situation of the system resources every other transmission period, thereby realizing the dynamic configuration of the reserved resources.

It should be noted that, when the dynamic configuration of the reserved resources is implemented, the base station may configure the reserved resources periodically, for example, every 1 TTI or 1 data frame, or configure the reserved resources aperiodically.

In the embodiment of the present invention, if there are multiple UEs that send emergency services to the base station through the reserved resources, the base station side may increase the receiving in order to prevent the uplink emergency services sent by the multiple UEs from colliding on the reserved resources. The number of antennas is multi-user MIMO (Multiuser MIMO, Multiple Input Multiple Output) technology to distinguish emergency services transmitted by different UEs.

The method for transmitting the uplink emergency service shown in FIG. 2 is implemented, and the base station reserves resources for the uplink emergency service. When the UE has an emergency service to be sent to the base station, the UE does not need to send a scheduling request to the base station as before sending the non-emergency service (SR). And waiting for the base station to be scheduled to transmit the service through the resources allocated by the base station, and directly transmitting the uplink emergency service to the base station through the resources reserved by the base station in the current TTI, so as to implement fast transmission of the uplink emergency service.

In the embodiment of the present invention, the uplink emergency service may include: control information and data information. The control information of the uplink emergency service may include the information indicating the modulation and coding mode, the redundancy version of the HARQ retransmission, and the like, and may also include the indication information of the resource occupied by the data information. In the embodiment of the present invention, the indication information is referred to as the second indication information. . In the embodiment of the present invention, the second indication information is used to indicate that the data information accounts for What resources are used?

It can be understood that, because the control information includes the second indication information, that is, the indication information of the data information of the uplink emergency service, the base station can find the resource used by the data information of the uplink emergency service according to the second indication information. And can receive data information through resources used by data information.

In the embodiment of the present invention, the reserved resources are not excessive, and the transmission of the uplink emergency service can be supported, thereby avoiding wasting system resources. However, in order to ensure correct and efficient transmission of the uplink emergency service, the reserved resource needs to support at least the transmission of the control information of the uplink emergency service. In an implementation manner, the size of the reserved resource may be determined according to a data amount of control information of an uplink emergency service and a total data amount of all information (control information and data information), so that the reservation of the size is The amount of data that the resource can support to transmit can be greater than or equal to the amount of data of the control information, and does not exceed the total amount of data of the uplink emergency service. It should be noted that the size of the reserved resource may be determined according to the actual application requirement or the transmission experience of the uplink emergency service, etc., which is not limited in the embodiment of the present invention.

Specifically, the UE may send the control information to the base station by using the resource indicated by the first information, that is, the reserved resource. Correspondingly, the base station may receive the control information by using the resource indicated by the first indication information, that is, the reserved resource, and, because the control information includes the second indication information, the base station may The second indication information receives the data information by using the resource indicated by the second indication information.

In the embodiment of the present invention, part or all of the data information of the uplink emergency service may be transmitted through the unreserved resource. Here, the non-reserved resource refers to a system resource other than the reserved resource, and may include: a non-reserved resource that has been scheduled for the uplink non-emergency service, and a non-reserved resource that is not scheduled for the uplink non-emergency service. Among them, the resources in the non-reserved resources that are not scheduled for non-emergency services are idle resources.

In the embodiment of the present invention, if the non-reserved resources occupied by the part or all of the data information are also scheduled to be non-emergency services, there is an uplink resource conflict. That is to say, when the resources scheduled for the uplink non-emergency service are partially or completely the same as the resources scheduled for the uplink emergency service data, an uplink resource conflict occurs.

In order to avoid resource conflict between the uplink emergency service and the uplink non-emergency service, the UE may send the part or all of the data information by using the idle resource.

In a specific implementation, the base station may determine the idle resource from the non-reserved resource according to the uplink resource scheduling information, and broadcast the indication information of the idle resource, where the indication information is used in the embodiment of the present invention. The third indication information is used to instruct the UE to send the part or all of the data information by using the idle resource. The third indication information is used to indicate the idle resource, and the uplink resource scheduling information is used to indicate that the resource that has been scheduled for the non-emergency service. In an actual application, the base station may send the third indication information to the UE by using a physical control channel (PDCCH) or a physical broadcast channel (PBCH). And, like the control information of the non-emergency service, the third indication information may also be distributed and transmitted in frequency and time to obtain a diversity gain.

Correspondingly, after receiving the third indication information sent by the base station, the UE may send the part or all of the data information according to the resource indicated by the third information, that is, the idle resource.

In a specific implementation, the UE may randomly select an idle resource for transmitting the data information from the resource indicated by the third indication information, that is, the idle resource, according to the third indication information, and select, by using, The idle resource sends the data information.

In the embodiment of the present invention, the third indication information may be a resource bitmap (Bit-map) for characterizing a scheduling situation of the non-reserved resource, where a data bit (bit) in the resource bitmap ) is used to mark whether a resource scheduling unit has been scheduled for the non-emergency service. It can be understood that since the resource bitmap uses bits to store data, the storage overhead can be greatly saved.

Specifically, the resource scheduling unit is used to indicate the minimum resource unit involved in performing uplink scheduling by the base station, and may be an RB pair in the LTE communication system, or may be a time slot in the GSM communication system. In a specific implementation, a data bit of 1 indicates that the resource scheduling unit corresponding to the data bit is occupied by a non-emergency service, and a data bit of 0 indicates that the resource scheduling unit corresponding to the data bit is idle. In an actual application, the data scheduling unit corresponding to the data bit may be occupied by the non-emergency service, and the data bit is 1 to indicate that the resource scheduling unit corresponding to the data bit is idle, and is not limited herein.

In another implementation manner, the base station may broadcast indication information of the idle resource in the current TTI to all user equipments in the cell at the start time of the current TTI, that is, the resource bitmap is used for Indicates idle resources in the current TTI.

In the implementation manner of the above two kinds of broadcasting of the third indication information, the previous implementation requires less broadcast times, but the amount of data broadcasted each time is larger; the latter implementation requires more broadcast times (each The start time of the TTI), but the amount of data broadcast each time is small. The specific implementation may be performed according to the actual application requirements. For example, the previous implementation manner is suitable for an application scenario with a low service load, and the subsequent implementation manner is suitable for an application scenario with a high service load, which is not limited herein.

It can be understood that, because the control information may include: second indication information, that is, indication information of idle resources occupied by data information of the uplink emergency service, the base station can find the data information according to the second indication information. An idle resource and capable of receiving the data information through an idle resource used by the data information.

In the embodiment of the present invention, if the amount of data that the reserved resource can support is greater than the amount of data of the control information, the UE may transmit part of the data information of the uplink emergency service through the reserved resource, and another part of the data. Information is transmitted through the idle resource. It can be understood that, at this time, the resource indicated by the second indication information may include two parts, where part is a reserved resource occupied by the data information, and another part is an idle resource occupied by the data information.

In the embodiment of the present invention, if there are multiple UEs simultaneously transmitting data information of the emergency service to the base station through the same idle resource, the data information of the uplink emergency service sent by the multiple UEs is prevented from colliding on the same idle resource. The base station side can increase the number of receiving antennas and use multi-user MIMO technology to distinguish data information sent by different UEs.

The UE may further determine the idle resource by using the foregoing step of receiving the third indication information sent by the base station, and the UE may further determine the idle resource for the uplink non-emergency service broadcast by the base station, according to the foregoing. The resource scheduling information analyzes the unreserved resources that have been scheduled for the uplink non-emergency service, and then analyzes the idle resources according to the unreserved resources that have been scheduled for the uplink non-emergency service. Here, the idle resource refers to the unscheduled resource. Non-reserved resources for uplink non-emergency services. Finally, the UE may send part or all of the data information by using the idle resource, so as to avoid resource conflict between the uplink emergency service and the uplink non-emergency service.

Specifically, the specific implementation manner of the base station broadcasting the resource scheduling information for the uplink non-emergency service may be: the base station sends the resource scheduling information that is not scrambled by using the UE identifier information (UE ID), so that the UE that sends the uplink emergency service is sent. It can also demodulate the resource scheduling letter for uplink non-emergency services. Information, and analyzes which of the scheduled non-reserved resources are, thereby determining the unreserved resources that are not scheduled for the uplink non-emergency service, that is, the idle resources.

It can be understood that, if the data information of the uplink emergency service is not sent by the idle resource, part or all of the data information of the uplink emergency service sent by the unreserved resource may be in conflict with the uplink non-emergency service, and the uplink emergency service and Signals for uplink non-emergency services are superimposed at the base station and interfere with each other. In the embodiment of the present invention, if the data information of the uplink emergency service is not sent by the idle resource, in order to enable the base station to correctly demodulate the part or all of the data information on the non-reserved resource that may cause the uplink resource conflict, the UE may The part or all of the data information is sent by the following two methods: first, raising the transmission power of the part or all of the data information; second, using low-order modulation for the part or all of the data information. It should be noted that, in an actual application, the UE may also use other methods, such as retransmitting part or all of the data information multiple times, so that the base station can correctly demodulate the part or all of the data information, and finally ensure the priority transmission of the uplink emergency service. .

It should be noted that the first, second, third, and other expressions used in the embodiments of the present invention are only used to distinguish the various indication information involved in the embodiments of the present invention, and are not used to limit the order.

In the embodiment of the present invention, the base station reserves resources for the uplink emergency service. When the UE has an emergency service to be sent to the base station, the UE can directly send the uplink emergency service to the base station through the resources reserved by the base station, and implement the uplink emergency service in time. And transmitting, if part or all of the data information of the uplink emergency service needs to be sent through the non-reserved resource, the UE may send the part or all of the data information by using the idle resource, thereby avoiding resource conflict with the non-emergency service.

Embodiments of the inventive method in an LTE (4G) communication system are described in detail below in conjunction with Figures 3A-3C. The LTE communication system is an Orthogonal Frequency Division Multiplexing (OFDM) system, and the resources involved are mainly time-frequency resources. The time-frequency resource can usually be represented by a resource block (RB) and a resource element (Resource Element, RE). RB refers to a continuous 180 kHz in frequency (12 subcarriers when the subcarrier spacing is 15 kHz), and 1 time slot in the time domain (1 time slot in LTE is 0.5 ms, and regular cyclic prefix length is 7). OFDM or SC-FDMA symbols); RE refers to one subcarrier on frequency, one OFDM or SC-FDMA symbol in the time domain.

Referring to FIG. 3A, FIG. 3A illustrates an allocation of uplink time-frequency resources in an LTE system.

As shown in FIG. 3A, the control information of the uplink non-emergency service is carried on a Physical Uplink Control Channel (PUCCH), and the PUCCH is spectrally located at both ends of the system bandwidth. The data information of the uplink non-emergency service is carried on a Physical Uplink Shared Channel (PUSCH). Through base station scheduling, the PUSCH can use time-frequency resources that are not used by the PUCCH. For example, as shown in FIG. 3A, at a certain TTI, the PUSCH uses a certain time-frequency resource in the middle of the spectrum in the figure.

The reserved resource 401 in FIG. 3A is a time-frequency resource reserved by the base station for uplink emergency services. As shown in FIG. 3A, within a single TTI, the reserved resource 401 may occupy M SC-FDMA symbols in the time domain and occupy N subcarriers in the frequency domain. The K resource factors RE formed by the intersection of the M SC-FDMA symbols and the N subcarriers in the frequency domain; M, N, K are positive integers, where K = M * N. That is to say, the reserved resource 401 is composed of K resource factors (RE). Preferably, the reserved resource 401 can cover the entire TTI in the time domain as shown in FIG. 3A, and can enable the UE to send an uplink emergency service in any one of the SC-FDMA symbols in the single TTI. Send unpredictable bursts of upstream emergency services. Preferably, the reserved resource 401 can be all in the PUSCH in the frequency domain as shown in FIG. 3A, so that the transmission of the uplink emergency service does not affect the transmission of the control information of the uplink non-emergency service.

In the embodiment of the present invention, in the process of transmitting the uplink emergency service, the control information 402 and the data information 403 may occupy the same SC-FDMA symbol as shown in FIG. 3A, and synchronous transmission of the control information 402 and the data information 403 may be implemented.

It should be noted that, in practical applications, the control information 402 and the data information 403 may also occupy different SC-FDMA symbols, that is, there is a delay between the control information 402 and the data information 403. For example, in the reserved resource 401, the control information 402 occupies the i-th SC-FDMA symbol, and the data information 403 occupies the i+1th SC-FDMA symbol, and the control information 402 and the data information 403 can both pass the reserved resource 401. Transmission, transmission of emergency services does not affect the transmission of non-emergency services, i is a positive integer. The example is only one implementation of the embodiment of the present invention, and may be different in practical applications. For example, there is a delay of two SC-FDMA symbols between the control information 402 and the data information 403, which is not limited herein.

In the embodiment of the present invention, since the emergency service requires a short transmission time, the emergency service needs to occupy as few SC-FDMA symbols as possible.

Taking FIG. 3A as an example, the control information 402 and the data information 403 occupy a total of one SC-FDMA symbol. In Within the reserved resource 401, if the RE on the SC-FDMA symbol is insufficient to support the transmission of all data (control information 402 and data information 403) of the uplink emergency service, the UE may pass the SC in addition to the reserved resource 401. The RE occupied by the non-emergency service on the -FDMA symbol transmits part or all of the data information 403. That is to say, the part or all of the data information 403 may use the same time-frequency resources as the uplink non-emergency services of other users, resulting in resource conflicts.

In order to avoid resource conflict between the uplink emergency service and the uplink non-emergency service, in the embodiment of the present invention, the UE may send the part or all of the data information by using the unreserved resource, that is, the idle resource in the resource other than the reserved resource 401. 403. Here, the idle resource refers to a resource in the non-reserved resource that is not scheduled for uplink non-emergency services.

According to the content of the method embodiment of FIG. 2, the base station may notify the UE of the idle resource by using the third indication information. Moreover, the third indication information may be a resource bitmap (Bit-map) for characterizing a scheduling situation of the non-reserved resource, which may greatly save storage overhead.

In the LTE communication system, the system bandwidth is N RBs, and the base station broadcasts the indication information of the idle resources in the future M TTIs to the UE through the resource bitmap, where N and M are positive integers. The resource bitmap can be as shown in FIG. 3B. Since the smallest resource scheduling unit is an RB pair, one bit can be used to mark whether an RB pair has been scheduled for the non-emergency service. A value of 0 indicates that the RB pair corresponding to the bit is not scheduled for non-emergency services, that is, the RB pair is idle. If the value of the bit is 1, it indicates that the RB pair corresponding to the bit has been scheduled to be non-emergency. business. It can be understood that the data amount of the resource bitmap shown in FIG. 5 is: N*M bits. Further, in order to reduce data transmission overhead, the resource bitmap may include only non-reserved resources other than the reserved resource 401, that is, only bit information other than the shadow. It can be understood that the data amount of the resource bitmap corresponding only to the non-reserved resources is reduced to: (N-2)*M bits.

The UE may further determine the idle resource by using the foregoing step of receiving the third indication information sent by the base station, and the UE may further determine the idle resource for the uplink non-emergency service broadcast by the base station, according to the foregoing. The resource scheduling information analyzes the unreserved resources that have been scheduled for the uplink non-emergency service, and then analyzes the idle resources according to the unreserved resources that have been scheduled for the uplink non-emergency service. Here, the idle resource refers to the unscheduled resource. Non-reserved resources for uplink non-emergency services. Finally, the UE may send the part or all of the data information 403 by using the idle resource, so as to avoid resource conflict between the uplink emergency service and the uplink non-emergency service.

In the embodiment of the present invention, if the part or all of the data information 403 is not sent by the idle resource, when the uplink emergency service and the uplink non-emergency service have a resource conflict, the uplink emergency service and the uplink non-emergency service signal are at the base station. Superimposed at each other, mutual interference. In this scenario, in order for the base station to correctly demodulate the part or all of the data information 403, the UE may adopt the following methods: first, raise the transmit power of the part or all of the data information 403; Low-order modulation is applied to the part or all of the data information 403. It should be noted that, in an actual application, the UE may further retransmit the part or all of the data information 403 on multiple REs, so that the base station can correctly demodulate the part or all of the data information 403, and finally ensure uplink. Priority transmission of emergency services.

It should be noted that, in practical applications, in addition to the case shown in FIG. 3A, the control information 402 and the data information 403 may occupy 2 (or more) SC-FDMA symbols.

It can be understood that, in order to make the base station aware of the UE that sends the uplink emergency service, the control information of the uplink emergency service needs to carry the User Equipment Identity (UE ID).

Referring to FIG. 3C, FIG. 3C illustrates another allocation of uplink time-frequency resources in the LTE system.

As shown in FIG. 3C, the base station can simultaneously receive uplink emergency services transmitted from two UEs (e.g., UE3 and UE4 in FIG. 3C) in one symbol. In an actual application, the base station may simultaneously receive uplink emergency services sent by two or more UEs in one symbol.

In the embodiment of the present invention, the REs occupied by the reserved resources may be statically configured, that is, remain unchanged for a long time; the REs occupied by the reserved resources may also be dynamically re-routed from the system resources according to the scheduling situation of the system resources. Selected. It should be noted that the base station can dynamically allocate reserved resources periodically, for example, every other TTI or one data frame, or dynamically allocate resources in a non-periodic manner.

In order to implement the reserved resource, the base station may change according to the transmission period of the data frame, and the base station may send the first indication information to the UE by using a control channel (PDCCH) in each TTI. And, like the control information of the non-emergency service, the first indication information may also be distributed and transmitted in frequency and time to obtain a diversity gain.

It should be noted that the time-frequency resource allocation implementation manner in the foregoing LTE communication system is also applicable to future communication systems (such as 4.5G, 5G), and the future communication system also has the concept of sub-carriers in the frequency direction, and also has symbols in the time direction ( Concepts like OFDM symbols, SC-FDMA symbols).

The present invention provides a method for transmitting uplink emergency services by using the time-frequency resources for transmitting uplink emergency services from the time-frequency resources of the LTE system, and the UE can directly pass the reserved time-frequency resources. The uplink emergency service is sent to the base station, and the uplink emergency service can be transmitted in time; and if part or all of the data information of the uplink emergency service needs to be sent through the unreserved resource, the UE may send the idle time-frequency resource by using the idle time-frequency resource. Part or all of the data information to avoid resource conflicts with non-emergency services.

In addition, embodiments of the present invention also provide an implementation of the solution of the present invention in a GSM (2G) communication system. The GSM communication system is a Time Division Multiple Access (TDMA) communication method, and the resources involved are mainly time slots.

Referring to FIG. 4, as shown in FIG. 4, a data frame includes 8 time slots, that is, 8 physical channels. The time length of one time slot is 0.577 ms. Multiple frames may constitute a multiframe. For example, 26 multiframes consist of 26 TDMA multiframes with a time interval of 120 ms.

In order to ensure timely transmission of uplink emergency services, the base station may reserve time slots for transmitting uplink emergency services from a plurality of time slots included in the data frame. Here, the reserved time slot is the reserved resource.

It can be understood that, after the UE receives the instruction for transmitting the uplink emergency service to the base station, the UE can directly transmit the uplink emergency to the base station by using the reserved time slot in the data frame (such as time slot 3 in FIG. 3). The service does not need to request the base station to allocate transmission slots.

After the time slot for transmitting the uplink emergency service is reserved, the base station may notify the UE of the reserved time slot to indicate that the UE can send the uplink emergency service to the base station by using the reserved time slot.

In the embodiment of the present invention, in the process of transmitting the uplink emergency service to the base station, the UE may send the control information of the uplink emergency service to the base station by using the reserved time slot; the control information may include: the uplink emergency service The information of the time slot occupied by the data information.

In the embodiment of the present invention, the UE may send part or all of the data information of the uplink emergency service through the unreserved time slot. Here, the non-reserved time slot refers to a time slot other than the reserved time slot. In order to avoid the collision between the uplink emergency service and the uplink non-emergency service, the UE may send the part or all of the data information through the idle time slot, that is, the unreserved time slot that is not scheduled for the non-emergency service.

In a specific implementation, the base station may determine, according to the uplink resource scheduling information, the non-reserved time slot. The idle time slot, and the third indication information is broadcasted to indicate that the UE sends the part or all of the data information by using the time slot indicated by the third indication information. Correspondingly, after receiving the third indication information, the UE may send the part or all of the data information by using the idle indication slot indicated by the third indication information according to the third indication information.

Here, the third indication information may be a resource bitmap for characterizing a scheduling situation of the non-reserved time slot. For example, FIG. 5 shows a resource bitmap corresponding to a data frame, where 1 bit is used to mark whether 1 time slot has been scheduled for non-emergency services, and if the bit value is 1, it indicates when the bit corresponds. The slot is scheduled for non-emergency services. If the bit value is 0, it indicates that the time slot corresponding to the bit is not scheduled for non-emergency services. Further, in order to reduce data transmission overhead, the resource bitmap may include only non-reserved resources other than reserved resources 401 (ie, reserved slot 0 and reserved slot 1), that is, only including shadows. Bit information.

It should be noted that the resource bitmap shown in FIG. 5 is only an implementation manner of the embodiment of the present invention, and may be different in practical applications, and should not be limited. In practical applications, in addition to a single data frame, the resource bitmap may be used to represent the at least 2 data frames, one (or at least 2) multi-frames, for at least 2 data frames, multi-frames, or super frames. Scheduling of non-reserved time slots within one (or at least 2) superframes.

It can be understood that, in order for the base station to know which UE the uplink emergency service is sent, the control information of the uplink emergency service also needs to carry the user equipment identifier (UE ID).

The present invention provides a method for transmitting uplink emergency services by using a time slot resource for transmitting uplink emergency services. After the UE receives an instruction to transmit uplink emergency services to the base station in the current TTI, the UE may The uplink emergency service is directly sent to the base station by using the reserved time slot, and the uplink emergency service can be transmitted in time; and if part or all of the data information of the uplink emergency service needs to be sent through the non-reserved time slot, the UE can The part or all of the data information is sent through the idle time slot, thereby avoiding resource conflicts with non-emergency services.
