第五代(5th generation，5G)移动通信***中，终端设备可以向网络设备发送资源调度请求(scheduling request，SR)以请求上行共享信道(physical uplink sharechannel，PUSCH)资源。In the 5th generation (5G) mobile communication system, a terminal device can send a resource scheduling request (scheduling request, SR) to a network device to request physical uplink share channel (PUSCH) resources.
目前，终端设备需要将SR承载在物理上行控制信道(physical uplink control channel，PUCCH)资源上发送，用于承载SR的PUCCH资源为该终端设备发送SR的专有资源，通常来说，该专有资源不能被其他终端设备或者其他信息占用。然而，在5G***的非授权频谱中，由于需要占用足够的带宽以满足占用信道带宽(occupied channel bandwidth，OCB)的需求，因此在发送上行信息时需要采用交错(interlace)的结构以在频域上占用更多的物理资源块(physical resource block，PRB)，进而，使用SR的专有资源发送SR信息时，尽管只有1比特的信息量，仍然需要分配多个PRB。显然，使用多个PRB发送1比特的信息量会造成资源的浪费。At present, the terminal device needs to bear the SR on the physical uplink control channel (PUCCH) resource and send it. The PUCCH resource used to carry the SR is the exclusive resource for the terminal device to send the SR. Generally speaking, the exclusive Resources cannot be occupied by other terminal devices or other information. However, in the unlicensed spectrum of the 5G system, because sufficient bandwidth needs to be occupied to meet the occupied channel bandwidth (OCB) requirements, it is necessary to use an interlace structure to transmit uplink information in the frequency domain. It occupies more physical resource blocks (PRBs). Furthermore, when SR dedicated resources are used to send SR information, although there is only one bit of information, multiple PRBs still need to be allocated. Obviously, using multiple PRBs to send 1 bit of information will cause a waste of resources.

目前，为了满足OCB的需求，使用SR的专用资源发送SR信息时，尽管只有1比特的信息量，仍然需要分配多个PRB，显然，使用多个PRB发送1比特的信息量会造成资源的浪费。基于此，本申请实施例提供一种SR信息的传输方法，该方法中，终端设备接收网络设备发送的SR的标识和第一信息，并根据该第一信息确定目标资源，该目标资源为第一资源中能够发送与该SR的标识对应的SR传输状态的资源，该第一资源用于发送上行控制信息和 /或上行数据。终端设备在该目标资源上向网络设备发送该SR传输状态，进而，网络设备在该目标资源上接收终端设备发送的该SR传输状态。基于该方案，由于终端设备可以根据网络设备发送的第一信息，在用于发送上行控制信息和/或上行数据的第一资源中确定目标资源，并在该目标资源上发送SR的标识对应的SR传输状态，因此，相对于现有技术中终端设备在SR专有资源上向网络设备发送SR信息的方案，可以减少资源浪费。At present, in order to meet the needs of OCB, when using SR dedicated resources to send SR information, although there is only 1 bit of information, multiple PRBs still need to be allocated. Obviously, using multiple PRBs to send 1 bit of information will cause a waste of resources. . Based on this, an embodiment of the present application provides a method for transmitting SR information. In this method, a terminal device receives an SR identifier and first information sent by a network device, and determines a target resource based on the first information, where the target resource is the first information.

The terminal device sends the SR transmission status to the network device on the target resource, and further, the network device receives the SR transmission status sent by the terminal device on the target resource. Based on this solution, the terminal device can determine the target resource in the first resource used to send uplink control information and/or uplink data according to the first information sent by the network device, and send the corresponding SR identifier on the target resource The SR transmission state, therefore, compared with the prior art solution in which the terminal device sends SR information to the network device on the SR dedicated resource, resource waste can be reduced.

其中，SR的标识为步骤S401中终端设备接收的网络设备发送的SR的标识。The identifier of the SR is the identifier of the SR sent by the network device received by the terminal device in step S401.
可选的，本申请实施例中，第一信息包括的内容不同，终端设备根据第一信息确定目标资源的方法也不同，包括如下三种情况：Optionally, in the embodiment of the present application, the content included in the first information is different, and the method for the terminal device to determine the target resource according to the first information is also different, including the following three cases:
情况一、第一信息包括与SR的标识对应的目标资源的信息。相应的，终端设备根据该目标资源的信息确定目标资源。Case 1: The first information includes the target resource information corresponding to the identifier of the SR. Correspondingly, the terminal device determines the target resource according to the information of the target resource.
其中，第一资源的用途不同，目标资源的信息也不同，相应的，终端设备根据目标资源的信息确定的目标资源也不同，包括如下三种场景：Among them, the purpose of the first resource is different, and the information of the target resource is different. Accordingly, the target resource determined by the terminal device according to the information of the target resource is also different, including the following three scenarios:
①第一资源用于发送上行控制信息，且上行控制信息为CSI，目标资源的信息为与CSI有关的标识。① The first resource is used to send uplink control information, and the uplink control information is CSI, and the target resource information is an identifier related to CSI.
其中，与CSI有关的标识可以为CSI报告配置标识，也可以为CSI报告资源标识。Wherein, the identifier related to the CSI may be a CSI report configuration identifier or a CSI report resource identifier.
可选的，用于发送CSI的第一资源可以为CSI报告资源，CSI报告资源可以是用于传输周期CSI或者半静态CSI的PUCCH资源；或者也可以是用于发送半静态CSI的PUSCH资源。Optionally, the first resource used to send CSI may be a CSI report resource, and the CSI report resource may be a PUCCH resource used to transmit periodic CSI or semi-static CSI; or may also be a PUSCH resource used to send semi-static CSI.
可选的，上述SR的标识和与CSI有关的标识的对应关系可以为一一对应，即SR的标识对应的SR传输状态只能在一个CSI报告配置标识对应的CSI报告资源上发送。Optionally, the correspondence between the aforementioned SR identifier and the CSI-related identifier may be a one-to-one correspondence, that is, the SR transmission state corresponding to the SR identifier can only be sent on the CSI report resource corresponding to one CSI report configuration identifier.
示例性的，以SR的标识为SR标识1，目标资源的信息为CSI报告配置标识1为例，终端设备可以根据SR标识1与CSI报告配置标识1的对应关系，确定SR标识1对应的SR传 输状态的发送机会，如图5a所示，CSI报告配置标识1对应的CSI报告1在时间单元n+1和时间单元n+4发送，CSI报告配置标识2对应的CSI报告2在时间单元n+3和时间单元n+6发送。则终端设备根据SR标识1与CSI报告配置标识1的对应关系，可以确定SR标识1对应的SR传输状态的发送机会为CSI报告配置标识1对应的CSI报告1的发送时间单元，即时间单元n+1和时间单元n+4。进而终端设备根据SR标识1对应的SR传输状态的发送机会确定目标资源，该目标资源可以为时间单元n+1对应的CSI报告1的资源、时间单元n+4对应的CSI报告1的资源中的一个或多个。Exemplarily, taking the SR identifier as SR identifier 1, and the target resource information as CSI report configuration identifier 1, the terminal device can determine the SR corresponding to SR identifier 1 according to the correspondence between SR identifier 1 and CSI report configuration identifier 1. The transmission opportunity of the transmission status is shown in Figure 5a. CSI report 1 corresponding to CSI report configuration identifier 1 is sent in time unit n+1 and time unit n+4, and CSI report 2 corresponding to CSI report configuration identifier 2 is sent in time unit n +3 and time unit n+6 are sent. Then, the terminal device can determine that the transmission opportunity of the SR transmission state corresponding to SR identifier 1 is the transmission time unit of CSI report 1 corresponding to CSI report configuration identifier 1, namely time unit n, according to the correspondence between SR identifier 1 and CSI report configuration identifier 1. +1 and time unit n+4. Furthermore, the terminal device determines the target resource according to the transmission opportunity of the SR transmission state corresponding to the SR identifier 1.

其中，目标资源为一个时间单元对应的CSI报告资源还是多个时间单元对应的CSI报告资源可以根据实际情况，包括信道状态，终端设备设备当前是否需要发送数据以及以及终端设备的实现而定。例如，终端设备在t1时刻确定信道空闲，如果此时终端设备在SR标识1对应的一个或多个逻辑信道中有数据需要发送，且需要向网络设备请求资源，那么终端设备可以在时间单元n+1对应的CSI报告1的资源上发送CSI报告1以及SR标识1对应的SR传输状态，若在时间单元n+4之前，终端设备接收到网络设备为其调度的资源，则终端设备不再继续发送SR标识1对应的SR传输状态，在该场景下，目标资源即为时间单元n+1对应的CSI报告1的资源；或者，若在时间单元n+4之前，终端设备未接收到网络设备为其调度的资源，且时间单元n+4不在SR标识1对应的禁止传输时间内，终端设备可以在时间单元n+4的开始时刻确定信道是否空闲，若确定信道空闲，则终端设备在时间单元n+4对应的CSI报告1的资源上继续发送SR标识1对应的SR传输状态，在该场景下，目标资源即为时间单元n+1对应的CSI报告1的资源以及时间单元n+4对应的CSI报告1的资源。可以理解的是，实际应用中，终端设备也可以根据其他情况确定目标资源为一个时间单元对应的CSI报告资源还是多个时间单元对应的CSI报告资源，本申请实施例对此不做具体限定。Among them, whether the target resource is a CSI report resource corresponding to one time unit or a CSI report resource corresponding to multiple time units may be determined according to actual conditions, including channel status, whether the terminal device currently needs to send data, and the implementation of the terminal device. For example, the terminal device determines that the channel is idle at time t1. If the terminal device has data to send in one or more logical channels corresponding to SR identifier 1 and needs to request resources from the network device, then the terminal device can use time unit n CSI report 1 and the SR transmission status corresponding to SR ID 1 are sent on the resource of CSI report 1 corresponding to +1. If the terminal device receives the resource scheduled by the network device for it before the time unit n+4, the terminal device no longer Continue to send the SR transmission status corresponding to SR ID 1. In this scenario, the target resource is the resource of CSI report 1 corresponding to time unit n+1; or, if the terminal device does not receive the network before time unit n+4 The device is the resource scheduled by the device, and the time unit n+4 is not within the forbidden transmission time corresponding to the SR identifier 1, the terminal device can determine whether the channel is free at the beginning of the time unit n+4. If the channel is determined to be free, the terminal device is The resource of CSI report 1 corresponding to time unit n+4 continues to send the SR transmission status corresponding to SR identifier 1. In this scenario, the target resource is the resource of CSI report 1 corresponding to time unit n+1 and time unit n+ 4 corresponds to the resource of CSI report 1. It is understandable that in practical applications, the terminal device may also determine whether the target resource is a CSI report resource corresponding to one time unit or a CSI report resource corresponding to multiple time units according to other conditions, which is not specifically limited in the embodiment of the present application.

In addition, the terminal device can also determine that the CSI is sent in the time slots numbered 1, 5, and 9 according to the related configuration of the CSI, and the actual transmission opportunity of the SR transmission state corresponding to the above SR identifier finally determined by the terminal device is the configured SR transmission The transmission opportunity of the state overlaps or the same time slot as the transmission opportunity of the CSI, that is, the actual transmission opportunity of the SR transmission state corresponding to the above SR identifier is the time slot numbered 1, 5, and 9, and the target resource corresponds to the time slot 1. One or more of the CSI report resources corresponding to timeslot 5, and the CSI report resources corresponding to timeslot 9, where the target resource is the CSI report resource corresponding to one timeslot or the CSI corresponding to multiple timeslots Report resources can be determined according to actual conditions, including channel status, whether the terminal device currently needs to send data, and the implementation of the terminal device. For related description, please refer to the description of the one-to-one correspondence between the SR identifier and the CSI-related identifier, here No longer.
可选的，在该情况二中，网络设备可以将第一信息携带在SR的相关配置信息中。示例 性的，以SR的标识为SR标识为例，网络设备可以将第一信息携带在SR的配置信息中，此时，SR的配置信息的数据结构可以为：Optionally, in the second case, the network device may carry the first information in the related configuration information of the SR. Exemplarily, taking the SR identifier as the SR identifier as an example, the network device may carry the first information in the configuration information of the SR. At this time, the data structure of the configuration information of the SR may be:
SR标识(Scheduling Request ID)；SR identification (Scheduling Request ID);
SR禁止计数器(SR prohibit timer)；SR prohibit timer (SR prohibit timer);
SR传输最大次数(SR trans Max)；The maximum number of SR transmissions (SR trans Max);
SR偏的移值(SR offset-CSI)；SR offset (SR offset-CSI);
SR的周期(SR periodicity)。SR period (SR periodicity).
情况三、第一信息用于指示终端设备能够在第一资源上发送SR的标识对应的SR传输状态。Case 3: The first information is used to indicate that the terminal device can send the SR transmission status corresponding to the SR identifier on the first resource.
可选的，该第一信息可以为新定义的无线资源控制(radio resource control，RRC)信令。示例性的，该RRC信令可以为“simultaneous-SR-CSI”，用于指示终端设备能够在CSI报告资源上传输SR的传输状态；或者，该RRC信令可以为“simultaneous-SR-HARQ”，用于指示终端设备能够在HARQ资源上传输SR的传输状态。Optionally, the first information may be newly defined radio resource control (radio resource control, RRC) signaling. Exemplarily, the RRC signaling may be "simultaneous-SR-CSI", which is used to indicate that the terminal device can transmit the transmission status of the SR on the CSI report resource; or, the RRC signaling may be "simultaneous-SR-HARQ" , Used to indicate the transmission status of the terminal equipment capable of transmitting SR on HARQ resources.
相应的，在该情况三中，终端设备根据第一信息确定目标资源，包括：终端设备将信道空闲后的第一资源中的第一个资源确定为目标资源。其中，第一个资源为信道空闲后的第一资源中起始时间单元最小的资源，若存在多个资源的起始时间单元相同且最小，那么第一个资源为多个资源中服务小区标识最小的资源。Correspondingly, in the third case, the terminal device determining the target resource according to the first information includes: the terminal device determining the first resource among the first resources after the channel is idle as the target resource. Among them, the first resource is the resource with the smallest starting time unit among the first resources after the channel is idle. If there are multiple resources with the same and smallest starting time unit, then the first resource is the serving cell identifier among multiple resources. The smallest resource.
示例性的，如图8所示，以上行控制信息为CSI，第一资源为CSI报告资源为例，终端设备根据CSI的相关配置确定的第一资源包括CSI报告1对应的CSI报告资源、CSI报告2对应的CSI报告资源、CSI报告3对应的CSI报告资源、以及CSI报告4对应的CSI报告资源，CSI报告2和CSI报告4对应的CSI报告资源的起始时间单元相同。若终端设备在t1时刻确定信道空闲，则信道空闲后的第一资源中起始时间单元最小的资源包括CSI报告2对应的CSI报告资源以及CSI报告4对应的CSI报告资源。其中，CSI报告2对应的CSI报告资源所在服务小区的标识最小，因此，信道空闲后的第一资源中的第一个资源(即目标资源)为CSI报告2对应的CSI报告资源。需要说明的是，此处仅以上行控制信息为CSI为例对终端设备在情况三下确定目标资源的方法进行说明，可以理解的是，当上行控制信息为HARQ信息时，终端设备也可以采用类似的方法确定目标资源，在此不再赘述。Exemplarily, as shown in FIG. 8, the upper line control information is CSI, and the first resource is CSI report resource. For example, the first resource determined by the terminal device according to the related configuration of CSI includes CSI report resource corresponding to CSI report 1, and CSI report resource. The CSI report resource corresponding to report 2, the CSI report resource corresponding to CSI report 3, and the CSI report resource corresponding to CSI report 4, and the CSI report resources corresponding to CSI report 2 and CSI report 4 have the same starting time unit. If the terminal device determines that the channel is idle at time t1, the resource with the smallest initial time unit in the first resource after the channel is idle includes the CSI report resource corresponding to CSI report 2 and the CSI report resource corresponding to CSI report 4. Among them, the identity of the serving cell where the CSI report resource corresponding to CSI report 2 is located is the smallest. Therefore, the first resource (ie, target resource) in the first resource after the channel is free is the CSI report resource corresponding to CSI report 2. It should be noted that here only the upstream control information is CSI as an example to illustrate the method for the terminal device to determine the target resource in case three. It is understandable that when the uplink control information is HARQ information, the terminal device can also use A similar method is used to determine the target resource, which will not be repeated here.
可选的，上行控制信息为HARQ信息时，该第一信息也可以包含在下行控制信息(downlink control information，DCI)中，动态指示终端设备是否能够在该DCI调度的HARQ资源中传输SR传输状态。例如，在DCI中使用1比特指示该DCI调度的HARQ资源中是否能够传输SR传输状态，该比特取值为“1”时表示能够在该HARQ资源中传输SR传输状态，该比特取值为“0”时表示不能在该HARQ资源中传输SR传输状态。Optionally, when the uplink control information is HARQ information, the first information may also be included in downlink control information (DCI) to dynamically indicate whether the terminal device can transmit the SR transmission status in the HARQ resource scheduled by the DCI . For example, 1 bit is used in DCI to indicate whether the SR transmission status can be transmitted in the HARQ resource scheduled by the DCI. When the value of this bit is "1", it means that the SR transmission status can be transmitted in the HARQ resource, and the value of this bit is " 0" indicates that the SR transmission status cannot be transmitted in the HARQ resource.
相应的，终端设备接收到携带第一信息的DCI，且该第一信息指示终端设备能够在该DCI调度的资源上传输SR传输状态后，可以将携带第一信息的DCI调度的HARQ资源确定为发送SR的标识对应的传输状态的目标资源。Correspondingly, after the terminal device receives the DCI carrying the first information, and the first information indicates that the terminal device can transmit the SR transmission status on the resource scheduled by the DCI, it may determine the HARQ resource scheduled by the DCI carrying the first information as Send the target resource of the transmission state corresponding to the SR identifier.
示例性的，如图9所示，以4个时间单元的物理下行共享信道(physical downlink share channel，PDSCH)需要在同一个HARQ资源上反馈为例，网络设备可以在最后一个时间单元的DCI中携带第一信息，例如，使用1比特指示在该HARQ资源上能否传输SR传输状态；或者，为了防止最后一个时间单元的DCI丢失，网络设备可以在该4个时间单元的DCI中均携带相同的第一信息，例如，分别使用取值相同的1比特指示在该HARQ资源上能否传输SR传输状态。若第一信息指示终端设备能够在该HARQ资源上传输SR传输状态，则终端设备 可以将DCI指示的时间单元n+5对应的HARQ资源确定为发送SR的标识对应的SR传输状态的目标资源。Exemplarily, as shown in Figure 9, taking the physical downlink share channel (PDSCH) of 4 time units that need to be fed back on the same HARQ resource as an example, the network device can be in the DCI of the last time unit Carry the first information, for example, use 1 bit to indicate whether the SR transmission status can be transmitted on the HARQ resource; or, to prevent the loss of the DCI of the last time unit, the network device can carry the same in the DCI of the 4 time units The first information of, for example, uses 1 bit with the same value to indicate whether the SR transmission status can be transmitted on the HARQ resource. If the first information indicates that the terminal device can transmit the SR transmission status on the HARQ resource, the terminal device may determine the HARQ resource corresponding to the time unit n+5 indicated by the DCI as the target resource of the SR transmission status corresponding to the identifier of sending the SR.
上述三种情况中，除情况三外，在其余两种情况下网络设备没有显式地指示终端设备能够在第一资源上传输SR的传输状态。基于此，可选的，在情况一和情况二下，本申请实施例提供的SR信息的传输方法还包括：网络设备向终端设备发送第二信息。相应的，终端设备接收网络设备发送的第二信息，该第二信息用于指示终端设备能够在第一资源上发送SR传输状态。终端设备接收到该第二信息后，若需要发送步骤S401中接收的网络设备发送的SR的标识对应的SR传输状态，则根据上述情况一和情况二中的方法确定目标资源。In the above three cases, except for case three, in the other two cases, the network device does not explicitly indicate that the terminal device can transmit the transmission status of the SR on the first resource. Based on this, optionally, in case one and case two, the SR information transmission method provided in the embodiment of the present application further includes: the network device sends the second information to the terminal device. Correspondingly, the terminal device receives the second information sent by the network device, and the second information is used to indicate that the terminal device can send the SR transmission status on the first resource. After the terminal device receives the second information, if it needs to send the SR transmission status corresponding to the SR identifier sent by the network device received in step S401, the target resource is determined according to the methods in the above case 1 and case 2.
可选的，该第二信息可以为新定义的无线资源控制RRC信令。示例性的，该RRC信令可以为“simultaneous-SR-CSI”，用于指示终端设备能够在CSI报告资源上传输SR的传输状态；或者，该RRC信令可以为“simultaneous-SR-HARQ”，用于指示终端设备能够在HARQ资源上传输SR的传输状态。Optionally, the second information may be newly defined radio resource control RRC signaling. Exemplarily, the RRC signaling may be "simultaneous-SR-CSI", which is used to indicate that the terminal device can transmit the transmission status of the SR on the CSI report resource; or, the RRC signaling may be "simultaneous-SR-HARQ" , Used to indicate the transmission status of the terminal equipment capable of transmitting SR on HARQ resources.
S403、终端设备在目标资源上向网络设备发送SR的标识对应的SR传输状态。相应的，网络设备在目标资源上接收终端设备发送的SR的标识对应的SR传输状态。S403: The terminal device sends the SR transmission status corresponding to the SR identifier to the network device on the target resource. Correspondingly, the network device receives the SR transmission status corresponding to the SR identifier sent by the terminal device on the target resource.
其中，SR的标识为步骤S401中终端设备接收的网络设备发送的SR的标识。The identifier of the SR is the identifier of the SR sent by the network device received by the terminal device in step S401.
可选的，SR的标识对应的SR传输状态包括第一状态或第二状态，该第一状态可以为“正(postive)”表示请求资源状态，该第二状态可以为“负(Negative)”表示非请求资源状态。相应的，该SR的标识对应的SR传输状态在目标资源中的表现形式可能存在如下三种形式：Optionally, the SR transmission state corresponding to the SR identifier includes a first state or a second state. The first state may be "postive" to indicate the requested resource state, and the second state may be "Negative" Represents the status of unrequested resources. Correspondingly, the SR transmission status corresponding to the SR identifier may have the following three forms in the target resource:
形式一、该SR传输状态的第一状态通过对解调参考信号(demodulation reference signal，DMRS)采用第一目标调制符号调制后的第一DMRS表示，该SR传输状态的第二状态通过对该DMRS采用第二目标调制符号调制后的第二DMRS表示。其中，第一目标调制符号为采用预设调制方式对第一状态调制后得到的符号，第二目标调制符号为采用该预设调制方式对第二状态调制后得到的符号。Form 1: The first state of the SR transmission state is represented by the first DMRS modulated by the first target modulation symbol for the demodulation reference signal (DMRS), and the second state of the SR transmission state is expressed by the DMRS Represents the second DMRS modulated by the second target modulation symbol. The first target modulation symbol is a symbol obtained by modulating the first state using a preset modulation method, and the second target modulation symbol is a symbol obtained after modulating the second state using the preset modulation method.
可选的，该DMRS可以是目标资源上承载的第二个DMRS，也可以是终端设备根据预设规则确定的一个DMRS，本申请实施例对此不做具体限定。Optionally, the DMRS may be the second DMRS carried on the target resource, or may be a DMRS determined by the terminal device according to a preset rule, which is not specifically limited in the embodiment of the present application.
可选的，该表现形式一可以通过如下方式确定：Optionally, the expression form one can be determined in the following ways:
终端设备首先采用预设调制方式对SR的标识对应的SR传输状态进行调制，得到目标调制符号，该预设调制方式可以为二进制相移键控(binary phase shift keying，BPSK)，也可以为Pi/2BPSK。示例性的，以终端设备使用BPSK调制方式，并用1比特表示该SR传输状态为例，如下表1所示，该1比特取值为“1”表示第一状态，终端设备采用BPSK调制方式对该1比特进行调制得到第一目标调制符号“-1”；或者，该1比特取值为“0”表示第二状态，终端设备采用BPSK调制方式对该1比特进行调制得到第二目标调制符号“1”。The terminal device first modulates the SR transmission state corresponding to the SR identifier by using a preset modulation method to obtain the target modulation symbol. The preset modulation method can be binary phase shift keying (BPSK) or Pi /2BPSK. Exemplarily, take the terminal device using the BPSK modulation method and use 1 bit to indicate the SR transmission state as an example, as shown in Table 1 below, the value of this 1 bit is "1" to indicate the first state, and the terminal device uses the BPSK modulation method to This 1-bit is modulated to obtain the first target modulation symbol "-1"; or, the value of the 1-bit is "0" to indicate the second state, and the terminal device uses BPSK modulation to modulate the 1-bit to obtain the second target modulation symbol "1".

确定目标调制符号后，终端设备使用第一目标调制符号对目标资源上承载的一个DMRS进行调制得到第一DMRS，或者使用第二目标调制符号对该DMRS进行调制得到第二DMRS。示例性的，以该DMRS为序列A(n)为例，采用目标调制符号调制后的该DMRS可以表示为“A(n)·目标调制符号”，则第一DMRS可以表示为-A(n)，第二DMRS可以表示为A(n)。After determining the target modulation symbol, the terminal device uses the first target modulation symbol to modulate a DMRS carried on the target resource to obtain a first DMRS, or uses a second target modulation symbol to modulate the DMRS to obtain a second DMRS. Exemplarily, taking the DMRS as the sequence A(n) as an example, the DMRS modulated by the target modulation symbol may be expressed as "A(n)·target modulation symbol", and the first DMRS may be expressed as -A(n ), the second DMRS can be expressed as A(n).

形式三、SR的标识对应的SR传输状态直接通过1比特表示。Form 3: The SR transmission status corresponding to the SR identifier is directly represented by 1 bit.
可选的，该1比特取值为“1”表示第一状态，该1比特取值为“0”表示第二状态。在该形式三下，终端设备在目标资源上可以通过如下方式向网络设备发送该SR传输状态：Optionally, the 1-bit value "1" indicates the first state, and the 1-bit value "0" indicates the second state. In the third form, the terminal device can send the SR transmission status to the network device on the target resource in the following manner:
终端设备首先计算该1比特信息所需要占用的资源元素(resource element，RE)数量，然后在目标资源中确定一个符号，并从该符号对应的RE中确定一部分RE，该部分RE的数量与该SR传输状态需要占用的RE数量相同，最后丢弃该部分RE上映射的上行控制信息或上行数据，将表示该SR传输状态的1比特信息映射到该部分RE上发送给网络设备。其中，终端设备在目标资源中确定的一个符号可以为承载DMRS的符号之前或之后的第一个符号，或者也可以为预留的用于承载HARQ信息的符号之前或之后的第一个符号。The terminal device first calculates the number of resource elements (RE) that the 1-bit information needs to occupy, then determines a symbol in the target resource, and determines a part of RE from the RE corresponding to the symbol. The SR transmission state needs to occupy the same number of REs, and finally the uplink control information or uplink data mapped on the part of REs is discarded, and the 1-bit information indicating the transmission state of the SR is mapped to the part of REs and sent to the network device. Wherein, a symbol determined by the terminal device in the target resource may be the first symbol before or after the symbol carrying the DMRS, or may also be the first symbol before or after the symbol reserved for carrying HARQ information.
示例性的，以目标资源包括7个符号，每个符号对应12个RE，表示SR的标识对应的SR传输状态的1比特信息占用2个RE为例，如图10a所示，终端设备在目标资源中确定的一个符号为目标资源承载的第一个DMRS后的第一个符号(编号为2的符号)，从该符号对应的RE中确定的一部分RE可以为该符号对应的RE中编号为0和1的RE。此时，终端设备可以将符号2对应的RE0和RE1上映射的上行控制信息或上行数据丢弃，并将表示SR的标识对应的SR传输状态的1比特信息映射到符号2对应的RE0和RE1上。Exemplarily, the target resource includes 7 symbols, each symbol corresponds to 12 REs, and the 1-bit information representing the SR transmission status corresponding to the SR identifier occupies 2 REs as an example. As shown in FIG. 10a, the terminal device is in the target A symbol determined in the resource is the first symbol (symbol numbered 2) after the first DMRS carried by the target resource. A part of the REs determined from the REs corresponding to the symbol may be numbered as the REs corresponding to the symbol 0 and 1 RE. At this time, the terminal device can discard the uplink control information or uplink data mapped on RE0 and RE1 corresponding to symbol 2, and map the 1-bit information indicating the SR transmission status corresponding to the SR identifier to RE0 and RE1 corresponding to symbol 2 .
或者，示例性的，以目标资源包括7个符号，每个符号对应12个RE，表示SR的标识对应的SR传输状态的1比特信息占用2个RE为例，如图10b所示，终端设备在目标资源中确定的一个符号为用于承载HARQ信息的符号之后的第一个符号(编号为3的符号)，从该符号对应的RE中确定的一部分RE可以为该符号对应的RE中编号为0和1的RE。此时，终端设备可以将符号3对应的RE0和RE1上映射的上行控制信息或上行数据丢弃，并将表示SR的标识对应的SR传输状态的1比特信息映射到符号3对应的RE0和RE1上。Or, as an example, the target resource includes 7 symbols, each symbol corresponds to 12 REs, and 1-bit information representing the SR transmission status corresponding to the SR identifier occupies 2 REs as an example, as shown in FIG. 10b, the terminal equipment A symbol determined in the target resource is the first symbol (symbol numbered 3) after the symbol used to carry HARQ information, and a part of the REs determined from the REs corresponding to the symbol may be numbered in the REs corresponding to the symbol RE is 0 and 1. At this time, the terminal device can discard the uplink control information or uplink data mapped on RE0 and RE1 corresponding to symbol 3, and map the 1-bit information representing the SR transmission state corresponding to the SR identifier to RE0 and RE1 corresponding to symbol 3 .
可选的，终端设备除向网络发送SR的标识对应的SR传输状态外，在上述步骤S402的情况二和情况三中，终端设备还可以向网络设备发送SR的标识，以便网络设备确定目标资源上传输的SR传输状态对应的SR的标识，即以便网络设备确定哪个SR需要请求资源或不请求资源。当然，终端设备还可以采用其他方式告知网络设备目标资源上传输的SR传输状态对应的SR标识，本申请实施例对此不做具体限定。Optionally, in addition to sending the SR transmission status corresponding to the SR identifier to the network, the terminal device may also send the SR identifier to the network device in case 2 and case 3 of step S402, so that the network device can determine the target resource The identifier of the SR corresponding to the transmission status of the SR transmitted on the above, that is, the network device can determine which SR needs to request resources or does not request resources.

基于本申请实施例提供的SR信息的传输方法，由于终端设备可以根据网络设备发送的第一信息，在用于发送上行控制信息和/或上行数据的第一资源中确定目标资源，并在该目标资源上发送SR的标识对应的SR传输状态，因此，相对于现有技术中终端设备在SR专有资 源上向网络设备发送SR信息的方案，可以减少资源浪费。Based on the SR information transmission method provided by the embodiments of the present application, since the terminal device can determine the target resource in the first resource used to send uplink control information and/or uplink data according to the first information sent by the network device, and use the The SR transmission status corresponding to the SR identifier sent on the target resource, therefore, compared with the prior art solution in which the terminal device sends SR information to the network device on the SR dedicated resource, resource waste can be reduced.

The subsequent terminal device determines that the channel is idle at time t4. At this time, the terminal device can use the method in step S402 to determine the target resource from the first resource (the first resource corresponding to the target resource as the time unit n+6 in FIG. 11 is Example), and send the SR transmission status corresponding to the SR identifier that was not sent in time on the target resource, without waiting for the next SR transmission status configured by the network device, thereby increasing the SR sending opportunity and reducing the transmission time Extension.
