Description

一种上行资源分配方法、基站和用户终端Uplink resource allocation method, base station and user terminal

技术领域Technical field

本文涉及但不限于通信领域，尤其涉及一种上行资源分配方法、基站和用户终端。This document relates to, but is not limited to, the field of communications, and in particular, to an uplink resource allocation method, a base station, and a user terminal.

背景技术Background technique

随着LAA(LTE-Advanced，高级LTE)或称LTE-U(即：将LTE的优势拓展到非授权频段)的概念的提出，LTE(Long Term Evolution，长期演进)***通过对非授权频段的使用，能大大提高LTE***吞吐量，并且也会降低运营成本。但是，根据一些国家地区的管制要求，在使用非授权频段时，需要引入LBT(Listen Before Talk，先听后讲)机制即先对信道进行侦听，根据侦听结果确定信道是否为可用信道，如果为可用信道，则可以进行上行或下行业务数据、控制信令的传输。在LAA部署中，LTE***使用非授权频段，在有管制要求的国家、地区，也需要遵循基于LBT机制的***运营。With the concept of LAA (LTE-Advanced) or LTE-U (ie, extending the advantages of LTE to unlicensed bands), the LTE (Long Term Evolution) system passes the unlicensed frequency band. Use, can greatly improve the throughput of the LTE system, and will also reduce operating costs. However, according to the regulatory requirements of some countries and regions, when using unlicensed frequency bands, it is necessary to introduce a LBT (Listen Before Talk) mechanism to listen to the channel first, and determine whether the channel is an available channel according to the interception result. If it is an available channel, the transmission of uplink or downlink service data and control signaling can be performed. In the LAA deployment, the LTE system uses unlicensed frequency bands, and in countries and regions with regulatory requirements, it also needs to follow the system operation based on the LBT mechanism.

对于LTE上行传输，因为其本身特点，通常由基站进行资源分配，并且基站通过下行子帧上的UL Grant(上行授权)将上行资源分配信息通知给用户；用终端户接收到UL Grant后，按照UL Grant的指示，在相应的时、频资源上发送业务数据。按照目前LTE协议要求，发送UL Grant的下行子帧与其所指示的发送PUSCH(Physical Uplink Shared Channel，物理上行共享信道)的上行子帧之间至少有4个子帧间隔。假设基站在子帧n进行上行资源分配，在子帧(n+1)将UL Grant发送给用户终端，用户终端最快可以在子帧(n+5)上进行上行数据发送，也就是说，从基站进行上行资源分配到用户终端进行上行数据发送，最少也有5个子帧的时延，如果上行数据可以顺利发送，付出这样的时延代价是有效果的，但是，考虑到LBT机制很可能因为LBT竞争信道失败，这样用户终端是不能如期在子帧(n+5)上发送上行数据的，那么，显然浪费了子帧(n+5)的上行资源，并且增加了用户终端的等待时延。即使基站在通过LBT机制确定信道可用，但是在时隔5个子帧的时延即用户终端进行上行数据发送时，之前确定为可用的信道未必当前还是可用的，因此，如果此时信道已不可用，用户终端也是不能如期在子帧(n+5)上发送上行数据的，同样也浪费了子帧(n+5)的上行资源，并且也增加了用户终端的等待时延。For the LTE uplink transmission, the resource allocation is usually performed by the base station, and the base station notifies the user of the uplink resource allocation information by using the UL Grant (uplink authorization) on the downlink subframe; after receiving the UL Grant by the terminal user, The UL Grant indicates that the service data is sent on the corresponding time and frequency resources. According to the requirements of the current LTE protocol, there is at least four subframe intervals between the downlink subframe in which the UL Grant is transmitted and the uplink subframe in which the PUSCH (Physical Uplink Shared Channel) is transmitted. It is assumed that the base station performs uplink resource allocation in subframe n, and transmits the UL Grant to the user terminal in subframe (n+1), and the user terminal can perform uplink data transmission in the subframe (n+5) at the earliest, that is, The uplink resource allocation from the base station to the user terminal for uplink data transmission has a delay of at least 5 subframes. If the uplink data can be sent smoothly, it is effective to pay such a delay, but considering that the LBT mechanism is likely because The LBT contending for the channel fails, so that the user terminal cannot send the uplink data on the subframe (n+5) as scheduled, then obviously the uplink resource of the subframe (n+5) is wasted, and the waiting delay of the user terminal is increased. . Even if the base station determines that the channel is available through the LBT mechanism, when the time delay of 5 subframes, that is, the user terminal performs uplink data transmission, the channel determined to be available before is not always available, therefore, if At this time, the channel is no longer available, and the user terminal cannot send the uplink data on the subframe (n+5) as scheduled, and also wastes the uplink resources of the subframe (n+5), and also increases the waiting time of the user terminal. Delay.

本申请发明人发现，考虑到LBT机制的效率，在一次LBT竞争到信道后，最好可以对信道进行连续占用，这无论是对于提高LBT效率，还是减少用户等待延迟，都是有好处的，但是LBT连续占用信道，可能与上行资源分配结果相冲突，这也是一个需要解决的问题。The inventor of the present application has found that, considering the efficiency of the LBT mechanism, after an LBT competes for a channel, it is preferable to continuously occupy the channel, which is advantageous for improving LBT efficiency or reducing user waiting delay. However, the LBT continuously occupies the channel, which may conflict with the uplink resource allocation result, which is also a problem to be solved.

本申请旨在提供一种上行资源分配机制，能够在保证公平性的前提下，尽可能少的浪费上行资源，并且也能降低LBT冲突概率，减少用户等待延迟，进而使得信道容量最大化。The present application aims to provide an uplink resource allocation mechanism, which can waste uplink resources as little as possible under the premise of ensuring fairness, and can also reduce LBT collision probability, reduce user waiting delay, and thereby maximize channel capacity.

可选地，步骤101之前还包括：所述基站遵循获得的资源分配信息中的上行最少调度用户数对用户终端进行上行资源分配；所述基站进行上行LBT侦听，如果侦听结果是信道忙，则等待下一个CCA时隙再发起新的LBT侦听，直到基站的某个CCA侦听结果是信道空闲，则基站通过发送占用信号来占有信道；Optionally, before step 101, the base station further performs uplink resource allocation on the user terminal according to the uplink minimum number of scheduled users in the obtained resource allocation information; the base station performs uplink LBT interception, if the interception result is that the channel is busy Waiting for the next CCA time slot to initiate a new LBT interception until the CCA listening result of the base station is that the channel is idle, the base station occupies the channel by transmitting the occupied signal;

所述根据获得的资源分配信息向用户侧发送上行传输指示信息包括：基站等待最近的下行子帧，通过该下行子帧给被调度的用户发送上行传输指示信息，可选地，上行传输指示信息可以为UL Grant，所述上行传输指示信息中包括有表示在连续多个上行子帧上发送上行业务数据的资源分配信息和连续占用信息。其中，连续占用信息由获得的资源分配信息中的上行最少调度用户数确定。The sending the uplink transmission indication information to the user side according to the obtained resource allocation information includes: the base station waits for the latest downlink subframe, and sends the uplink transmission indication information to the scheduled user through the downlink subframe, optionally, the uplink transmission indication information. The uplink transmission indication information includes resource allocation information and continuous occupation information indicating that the uplink service data is sent in consecutive uplink subframes. The continuous occupation information is determined by the number of uplink minimum scheduling users in the obtained resource allocation information.

或者，可选地，Or, optionally,

步骤101之前还包括：所述基站根据获得的资源分配信息中的LBT传输成功率，按照LBT传输成功率设置对应用户终端的调度优先级，LBT传输成功率越大对应的用户终端被调度的优先级越高，并且遵循获得的资源分配信息中的上行最少调度用户数，基于获得的每个LBT传输成功率分别对所对应的用户终端进行上行资源分配，以确定调度结果。Before the step 101, the base station further includes: according to the LBT transmission success rate in the obtained resource allocation information, setting a scheduling priority corresponding to the user terminal according to the LBT transmission success rate, and the LBT transmission success rate is larger, and the corresponding user terminal is scheduled to be prioritized. The higher the level, and follow the obtained resource allocation letter The number of uplink minimum scheduled users in the information is used to perform uplink resource allocation on the corresponding user terminal based on each obtained LBT transmission success rate to determine a scheduling result.

其中，对于LBT传输成功率值较高的用户，可以提高调度优先级；以确定最终的调度结果如调度了哪些用户、都分别分配了哪些资源等。For a user with a high LBT transmission success rate, the scheduling priority can be increased; and the final scheduling result, such as which users are scheduled, which resources are allocated, and the like, are determined.

所述根据获得的资源分配信息向用户侧发送上行传输指示信息包括：基站接收到用户侧占用信道的占用信号，根据调度结果，通过最近的下行子帧给被调度的用户终端发送上行传输指示信息。可选地，上行传输指示信息可以为UL Grant。在上行传输指示信息中新增用于表示该上行传输指示信息对应用户终端是主调度用户终端或辅调度用户终端的主辅标识域，主辅标识域可以为1比特，比如：主辅标识域为1，表示该UL Grant对应主调度用户终端；主辅标识域为0，表示该UL Grant对应辅调度用户终端，或者反之。The sending the uplink transmission indication information to the user side according to the obtained resource allocation information includes: receiving, by the base station, an occupation signal of the occupied channel of the user side, and sending, by using the latest downlink subframe, the uplink transmission indication information to the scheduled user terminal according to the scheduling result. . Optionally, the uplink transmission indication information may be a UL Grant. Adding a primary and secondary identification domain for indicating that the uplink terminal corresponds to the user terminal is a primary scheduling user terminal or a secondary scheduling user terminal, and the primary and secondary identification domains may be 1 bit, for example, the primary and secondary identification domains are added to the uplink transmission indication information. A value of 1 indicates that the UL Grant corresponds to the primary scheduling user terminal; the primary and secondary identity fields are 0, indicating that the UL Grant corresponds to the secondary scheduling user terminal, or vice versa.

可选地，在UL Grant中还新增M比特的LBT截止符号限制域，LBT截止符号限制域占用的比特数目可以为1到

中的任意值。其中，M为在非授权频段上被调度的用户终端数目，数字14为目前协议规定的一个子帧的长度及一个子帧包括14个符号。需要说明的是，基站侧要指示用户侧哪个符号为CCA上限，即如果在上限符号之前不能竞争到信道，就不允许再发数据了，这个指示可以是半静态或动态的，可以在如上所述的UL Grant中指示，也可以在RRC(Radio Resource Control，无线资源控制)信令中指示，所用比特数目可以为[1比特，向上取整log₂(上行子帧内符号数目)]中的任意一个数值。Optionally, an M-bit LBT cutoff symbol restriction field is also added in the UL Grant, and the number of bits occupied by the LBT cutoff symbol restriction domain may be 1 to

Any value in . Where M is the number of user terminals scheduled on the unlicensed frequency band, the number 14 is the length of one subframe specified by the current protocol, and one subframe includes 14 symbols. It should be noted that the base station side indicates which symbol on the user side is the CCA upper limit, that is, if the channel cannot be contending before the upper limit symbol, the data is not allowed to be retransmitted. This indication may be semi-static or dynamic, and may be as above. The indication in the UL Grant may also be indicated in the RRC (Radio Resource Control) signaling, and the number of used bits may be [1 bit, round up log ₂ (number of symbols in the uplink subframe)] Any one value.

需要说明的是，因为由用户终端来执行上行LBT侦听，因此可能出现被基站调度上的用户终端因LBT侦听失败而无法竞争到信道的情况，因此，本可选方案中基站做了调度备份，即每个频域调度单元都会调度两个用户终端，分别为上述提到的主调度用户，辅调度用户。It should be noted that, since the uplink LBT is performed by the user terminal, the user terminal scheduled by the base station may not be able to contend to the channel due to the LBT interception failure. Therefore, the base station performs scheduling in this alternative. Backup, that is, each frequency domain scheduling unit will schedule two user terminals, which are the above-mentioned primary scheduling users and secondary scheduling users.

可选地，上行传输指示信息也就是非授权信道资源占用指示信息，可以包含对非授权信道的连续占用信息，该上行传输指示信息可以用1比特标识连续占用或者非连续占用。这里，假设LBT最大连续占用时长为N个子帧或OFDM符号，则该连续占用信息的比特数目为对log₂(N)向上取整的结果，其中，LBT最大连续占用时长为多比特。 Optionally, the uplink transmission indication information, that is, the unlicensed channel resource occupation indication information, may include continuous occupation information of the unlicensed channel, where the uplink transmission indication information may be continuously occupied or discontinuously occupied by the 1-bit identifier. Here, assuming that the LBT maximum consecutive occupation time is N subframes or OFDM symbols, the number of bits of the continuous occupation information is a result of rounding up log ₂ (N), wherein the LBT maximum continuous occupation time is multiple bits.

可选地，上行传输指示信息也就是非授权信道资源占用指示信息，其中如果不包含对非授权信道的连续占用信息，当上下行子帧配置不均衡时，一个下行子帧里可能要发送多个UL Grant，分别对应多个连续的上行子帧，则本实施例的方法还包括：在每个上行传输指示信息里新增一个域，用来指示该上行传输指示信息对应的上行子帧序号。其中，上行传输指示信息为UL Grant时，UL Grant可以是多种类型的，可以是对应多个U(上行)子帧的，也可以是对应1个U子帧的，从而解决了连续调度与CCA竞争之间的冲突。Optionally, the uplink transmission indication information, that is, the unlicensed channel resource occupation indication information, if the continuous occupation information of the unlicensed channel is not included, when the uplink and downlink subframe configuration is unbalanced, a downlink subframe may be sent more. Each of the UL grants corresponds to a plurality of consecutive uplink subframes, and the method in this embodiment further includes: adding a field in each uplink transmission indication information, indicating the uplink subframe sequence number corresponding to the uplink transmission indication information. . When the uplink transmission indication information is a UL Grant, the UL Grant may be of multiple types, and may be corresponding to multiple U (uplink) subframes, or may be corresponding to one U subframe, thereby solving continuous scheduling and Conflict between CCA competition.

所述上行传输指示信息中不包含对非授权信道的连续占用信息；The uplink transmission indication information does not include continuous occupation information of the unlicensed channel;

所述方法还包括：在每个上行传输指示信息中新增一个域，用来指示该上行传输指示信息对应的上行子帧序号。The method further includes: adding a field to each uplink transmission indication information, and indicating the uplink subframe number corresponding to the uplink transmission indication information.

本发明实施例的一种可选实施方式中，如图2所示，所述步骤101后还包括：In an optional implementation manner of the embodiment of the present invention, as shown in FIG. 2, after the step 101, the method further includes:

步骤102：接收来自用户侧按照上行传输指示信息发送的上行数据。Step 102: Receive uplink data sent by the user side according to the uplink transmission indication information.

可选地，在步骤101之后，步骤102之前，本实施例的方法还包括：Optionally, after the step 101, before the step 102, the method in this embodiment further includes:

用户侧收到来自基站侧的UL Grant后，按照其中的资源分配指示，以及连续占用指示，在后续连续多个上行子帧上发送上行业务数据。After receiving the UL Grant from the base station side, the user side sends the uplink service data in subsequent consecutive uplink subframes according to the resource allocation indication and the continuous occupation indication.

或者，or,

用户侧收到来自基站侧的UL Grant后，进行上行LBT侦听，如果本用户终端是主调度用户且侦听到信道空闲，则直接发送占用信号来占用信道；如果本用户终端是主调度用户且侦听到信道忙，则本次CCA侦听失败，等待下一个CCA时隙再发起新的LBT侦听；如果本用户终端是辅调度用户且侦听到信道空闲，则也发送占用信号来占用信道；此时，After receiving the UL Grant from the base station side, the user side performs uplink LBT interception. If the user terminal is the primary scheduling user and the channel is idle, the occupation signal is directly sent to occupy the channel; if the user terminal is the primary scheduling user And if the channel is busy, the current CCA interception fails, waiting for the next CCA time slot to initiate a new LBT interception; if the user terminal is a secondary scheduling user and the channel is detected to be idle, the occupancy signal is also sent. Occupy the channel; at this time,

基站根据检测到的占用信号，可以了解哪些用终端户LBT侦听竞争到信道，基站在授权载波上对所有发送占用信号的主、辅用户终端发送允许传输标识，该允许传输标识可以但不限于为1比特，比如为1表示允许该用户终端按照UL Grant指示在对应上行子帧上发送数据，为0表示该用户终端收到的UL Grant作废；或者反之；其中，允许传输标识可以携带在另一个UL Grant中发送，可以指示是用于允许哪个UL Grant指示在对应上行子帧上发送数据的，也可以无需指示，因为用户侧在本用户终端需要上传数据时是知道的。The base station can learn, according to the detected occupied signal, which terminal LBT is used to listen to the channel, and the base station sends an allowed transmission identifier to all the primary and secondary user terminals that send the occupied signal on the authorized carrier, and the allowed transmission identifier can be, but is not limited to, 1 bit, for example, 1 means that the user terminal is allowed to send data in the corresponding uplink subframe according to the UL Grant indication, and 0 means that the UL Grant received by the user terminal is invalid; or vice versa; wherein the allowed transmission identifier can be carried in another Transmitted in a UL Grant, the indication may be used to allow which UL Grant indication to send data on the corresponding uplink subframe. It is also possible to provide no indication, because the user side knows when the user terminal needs to upload data.

用户侧根据来自基站侧的允许传输标识，在允许传输标识显示允许时，确定在对应子帧上发送上行数据；在允许传输标识显示为不允许时，立即中断占用信号的发送，释放信道。The user side determines to send uplink data on the corresponding subframe according to the allowed transmission identifier from the base station side, and when the allowed transmission identifier is not allowed, immediately interrupts the transmission of the occupied signal and releases the channel.

可选地，所述方法还包括：Optionally, the method further includes:

如果主、辅用户终端的信道空闲(即主调度用户终端和辅调度用户终端均CCA成功)，可以由基站侧在授权载波上通过动态信令指示：可以采用MU-MIMO(Multi-User Multiple-Input Multiple-Output，多用户多输入多输出)方式让主、辅用户终端都传输，或者，只允许主调度用户终端传输所述上行数据，If the channels of the primary and secondary user terminals are idle (that is, the primary scheduling user terminal and the secondary scheduling user terminal are both successful in CCA), the base station side may indicate by dynamic signaling on the authorized carrier: MU-MIMO (Multi-User Multiple- may be adopted) The Input Multiple-Output (Multiple User Multiple Input Multiple Output) mode allows both the primary and secondary user terminals to transmit, or only allows the primary scheduling user terminal to transmit the uplink data.

如果主用户的信道空闲，辅用户的信道忙(即：所述主调度用户终端CCA成功，所述辅调度用户终端CCA未成功)，可以由基站侧在授权载波上通过动态信令指示：由主调度用户终端发送所述上行数据。If the channel of the primary user is idle, the channel of the secondary user is busy (ie, the primary scheduling user terminal CCA is successful, and the secondary scheduling user terminal CCA is unsuccessful), and may be indicated by the base station side on the authorized carrier by dynamic signaling: The primary scheduling user terminal transmits the uplink data.

如果主调度用户的信道忙，辅用户的信道空闲(即所述主调度用户终端CCA未成功，辅调度用户终端CCA成功)，可以由基站侧在授权载波上通过动态信令指示：由辅用户终端发送所述上行数据。If the channel of the primary scheduling user is busy and the channel of the secondary user is idle (that is, the primary scheduling user terminal CCA is unsuccessful and the secondary scheduling user terminal CCA is successful), the base station side may indicate by dynamic signaling on the authorized carrier: by the secondary user The terminal transmits the uplink data.

通过本发明实施例及其可选方案提供的技术方案可见，用户侧进行上行数据传输前，通过对上行最少调度用户数及LBT传输成功率的考虑，尽量选择LBT传输成功率高的用户为被调度用户，这样无疑在保证公平性的前提下，尽可能地避免了对上行资源的浪费，并且也降低了LBT冲突概率，减少了用户等待时延，从而提高了信道容量。According to the technical solution provided by the embodiment of the present invention and the optional solution, before the uplink data transmission is performed on the user side, the user with a high LBT transmission success rate is selected as the user with the minimum number of uplink scheduling users and the LBT transmission success rate. Scheduling users, this undoubtedly avoids the waste of uplink resources as much as possible under the premise of ensuring fairness, and also reduces the LBT collision probability, reduces the waiting delay of users, and thus improves the channel capacity.

本发明又一实施例提供了一种上行资源分配方法，如图3所示，包括步骤500～501：A further embodiment of the present invention provides an uplink resource allocation method, as shown in FIG. 3, including steps 500-501:

500、用户侧接收来自基站侧的上行传输指示信息；所述上行传输指示信息是所述基站根据资源分配信息发送的；500. The user side receives the uplink transmission indication information from the base station side, where the uplink transmission indication information is sent by the base station according to the resource allocation information.

501、所述用户侧按照接收到的所述上行传输指示信息发送上行业务数据。 501. The user side sends uplink service data according to the received uplink transmission indication information.

所述用户侧按照接收到的所述上行传输指示信息中的资源分配指示，以及连续占用指示，在后续连续多个上行子帧上发送上行业务数据。The user side sends uplink service data in subsequent consecutive uplink subframes according to the received resource allocation indication in the uplink transmission indication information and the continuous occupation indication.

下面结合实施示例对本发明实施例的方法进行详细描述。The method of the embodiment of the present invention will be described in detail below with reference to the embodiments.

图4为本发明实施例的上行资源分配方法的第一实施示例的流程示意图，第一实施示例中，假设由基站来执行上行LBT操作，LBT最大连续占用信道时长为4ms。如图4所示，包括步骤200～205：4 is a schematic flowchart of a first implementation example of an uplink resource allocation method according to an embodiment of the present invention. In the first implementation example, it is assumed that an uplink LBT operation is performed by a base station, and a maximum duration of LBT continuous channel occupation is 4 ms. As shown in FIG. 4, steps 200-205 are included:

步骤200、OAM实体配置基站的上行最少调度用户数X；Step 200: The OAM entity configures the number of uplink minimum scheduled users of the base station X;

步骤201、基站进行上行调度，保证调度上的用户终端的个数M不小于上行最少调度用户数X；Step 201: The base station performs uplink scheduling to ensure that the number M of user terminals on the scheduling is not less than the number of uplink minimum scheduled users X.

步骤200～步骤201所表示的过程中，假设采用手动配置方式，基站侧预先设置执行上行调度时的最少调度用户数X＝4个；基站根据该数目约束，对所有候选上行用户终端进行调度，最终在比如20MHz的非授权频段上能调度上的用户终端数为M个，而且M大于或等于4。In the process indicated by the step 200 to the step 201, it is assumed that the manual configuration mode is adopted, and the base station side presets the minimum number of scheduled users X=4 when performing uplink scheduling; the base station performs scheduling on all candidate uplink user terminals according to the number constraint. Finally, the number of user terminals that can be scheduled on an unlicensed band such as 20 MHz is M, and M is greater than or equal to 4.

步骤202、基站进行上行LBT侦听； Step 202: The base station performs uplink LBT interception.

步骤203、判断LBT侦听结果是否为信道空闲；如果是则进行步骤204；如果不是则返回步骤202。Step 203: Determine whether the LBT listening result is that the channel is idle; if yes, proceed to step 204; if not, return to step 202.

步骤201～步骤203所表示的过程中：因为有被调度上的上行用户终端，基站要进行上行LBT侦听：如果侦听结果是信道忙，则等待下一个CCA时隙再发起新的LBT侦听，直到基站在某CCA时隙的侦听结果是信道空闲，则进入步骤204。In the process represented by step 201 to step 203: because there is an uplink user terminal that is scheduled, the base station performs uplink LBT interception: if the interception result is that the channel is busy, wait for the next CCA time slot and then initiate a new LBT detection. Listening, until the base station's listening result in a CCA slot is that the channel is idle, then step 204 is entered.

步骤204：基站发送占用信号来占用信道，并等待最近的下行子帧，在该下行子帧上给被调度上的用户终端发送UL Grant信令，在UL Grant信令中携带有资源分配指示和连续占用指示。Step 204: The base station sends an occupation signal to occupy the channel, and waits for the latest downlink subframe, and sends UL Grant signaling to the scheduled user terminal in the downlink subframe, where the UL Grant signaling carries the resource allocation indication and Continuous occupancy indication.

第一实施示例中，由于要对信道连续占用4个子帧，因此基站在给M个用户终端发送的UL Grant中，新增2比特的连续占用指示，其中，00表示对信道连续占用1个子帧，01表示对信道连续占用2个子帧，10表示对信道连续占用3个子帧，11表示对信道连续占用4个子帧。In the first implementation example, the base station continuously occupies 4 subframes, so the base station adds a 2-bit continuous occupation indication to the UL Grant sent to the M user terminals, where 00 indicates that the subframe continuously occupies 1 subframe. 01 indicates that the channel continuously occupies 2 subframes, 10 indicates that the channel continuously occupies 3 subframes, and 11 indicates that the channel continuously occupies 4 subframes.

步骤205：用户终端收到基站发送的UL Grant后，按照其中的资源分配指示，以及连续占用指示，在后续连续多个上行子帧上发送上行业务数据。Step 205: After receiving the UL Grant sent by the base station, the user terminal sends the uplink service data in subsequent consecutive uplink subframes according to the resource allocation indication and the continuous occupation indication.

图5为本发明实施例的上行资源分配方法的第二实施示例的流程示意图，第二实施示例中，假设由用户终端来执行上行LBT操作，LBT最大连续占用信道时间为4ms。如图5所示，包括步骤300～310：FIG. 5 is a schematic flowchart of a second implementation example of an uplink resource allocation method according to an embodiment of the present invention. In a second implementation example, it is assumed that an uplink LBT operation is performed by a user terminal, and a maximum continuous occupied channel time of the LBT is 4 ms. As shown in FIG. 5, steps 300-310 are included:

步骤300、用户终端计算并反馈LBT传输成功率；Step 300: The user terminal calculates and feeds back an LBT transmission success rate.

步骤301、基站进行上行调度，保证调度上的用户终端的个数M不小于上行最少用户调度数X，并进行调度备份；Step 301: The base station performs uplink scheduling to ensure that the number M of user terminals on the scheduling is not less than the number of uplink minimum user scheduling X, and performs scheduling backup.

步骤300～步骤301所表示的过程中：假设采用手动配置方式，基站侧于预先设置执行上行调度时的上行最少调度用户数X＝4个，基站的上行调度要在该数目约束下进行，即基站被调度上的用户终端的数M不小于上行最少调度用户数X，并进行调度备份。In the process indicated by step 300 to step 301, it is assumed that the manual configuration mode is adopted, and the number of uplink minimum scheduling users in the uplink scheduling when the base station side is set in advance is X=4, and the uplink scheduling of the base station is performed under the constraint of the number, that is, The number M of user terminals on which the base station is scheduled is not less than the number of uplink minimum scheduled users X, and scheduled backup is performed.

步骤301之前，每个用户终端统计目标时间内(本实施例中假设目标时间为最近100ms)的用户终端自身的LBT传输成功率，并通过PUSCH(Physical Uplink Shared Channel，物理上行共享信道)或PUCCH(Physical Uplink Control Channel，物理上行控制信道)周期性向基站反馈该LBT传输成功率值。Before step 301, each user terminal counts the LBT transmission success rate of the user terminal itself in the target time (the target time is assumed to be the last 100 ms in this embodiment), and passes the PUSCH (Physical Uplink Shared Channel) or PUCCH. (Physical Uplink Control Channel, physical uplink control channel) periodically feeds back the LBT transmission success rate value to the base station.

而基站在调度前，可以读取所有候选用户终端最近一次反馈的LBT传输成功率，将LBT传输成功率较大的用户终端的调度优先级提高，并且遵循预先配置的上行最少调度用户数，确定最终的调度结果。The base station can read the LBT transmission success rate of the last feedback of all the candidate user terminals before scheduling, and improve the scheduling priority of the user terminal with the LBT transmission capability, and follow the pre-configured uplink minimum scheduling users. The final scheduling result.

步骤301中，由于由用户终端来做LBT侦听，因此可能出现基站调度上的用户终端因LBT侦听失败而无法竞争到信道，因此基站做调度备份，即每个频域调度单元都会调度两个用户终端，分别为主调度用户终端，辅调度用户终端。In step 301, since the user terminal performs LBT interception, the user terminal on the base station scheduling may fail to compete for the channel due to the LBT interception failure, so the base station performs scheduling backup, that is, each frequency domain scheduling unit schedules two. Each user terminal is a main scheduling user terminal and a secondary scheduling user terminal.

步骤302：基站根据调度结果，在最近的下行子帧上给被调度上的用户终端发送UL Grant。其中，Step 302: The base station sends a UL Grant to the scheduled user terminal on the latest downlink subframe according to the scheduling result. among them,

UL Grant中新增有主辅标识域，该域为1比特，本实施例中假设为1表示该UL Grant对应主调度用户终端，为0则表示该UL Grant对应辅调度用户终端。UL Grant中还新增M比特LBT截止符号限制域，该域占用比特数目可以为1到
