Description

上行CCA检测方法、装置、终端及计算机存储介质Uplink CCA detection method, device, terminal and computer storage medium

技术领域Technical field

本公开涉及通信领域，具体而言，涉及一种上行CCA检测方法、装置、终端及计算机存储介质。The present disclosure relates to the field of communications, and in particular, to an uplink CCA detection method, apparatus, terminal, and computer storage medium.

背景技术Background technique

目前，长期演进技术(Long-Term Evolution，简称LTE)的通信网络都是部署在授权载波中运营的，随着LTE的发展，一些公司提出了“建议研究LTE部署在非授权载波中的课题”，例如美国的高通公司认为：随着数据业务的快速增长，在不久的将来，授权载波将不能承受快速业务增长带来的巨大的数据量。考虑通过在非授权载波中部署LTE，以此来分担授权载波中的数据流量，可以解决业务增长带来的数据量压力。同时，非授权载波具有以下特点：一方面，由于非授权载波不需要购买，或者载波资源为零成本，因此非授权载波免费或低费用；另一方面，由于个人、企业都可以参与部署，设备商的设备也可以，因此非授权载波的准入要求低；再者，非授权载波具有共享性，通过多个不同***都运营其中时或者同一***的不同运营商运营其中时，可以考虑一些共享资源的方式，以提高载波效率。At present, the communication network of Long-Term Evolution (LTE) is deployed in the licensed carrier. With the development of LTE, some companies have proposed "recommended to study the problem of LTE deployed in unlicensed carriers." For example, Qualcomm in the United States believes that with the rapid growth of data services, in the near future, authorized carriers will not be able to withstand the huge amount of data brought by rapid business growth. Considering that LTE is deployed in an unlicensed carrier to share the data traffic in the authorized carrier, the data volume pressure brought by the service growth can be solved. At the same time, the unlicensed carrier has the following characteristics: on the one hand, since the unlicensed carrier does not need to be purchased, or the carrier resource is zero cost, the unlicensed carrier is free or low-cost; on the other hand, since the individual and the enterprise can participate in the deployment, the device The quotient equipment is also available, so the admission requirements of the unlicensed carrier are low; in addition, the unlicensed carrier is shared, and some sharing can be considered when multiple different systems are operating at the same time or when different operators of the same system operate. The way resources are used to improve carrier efficiency.

综上所述，虽然LTE部署在非授权载波中具有明显的优势，但是，在部署的过程中，依然存在问题；其中，无线接入技术多(跨不同的通信标准，协作难，网络拓扑多样)和无线接入站点多(用户数量大，协作难度大，集中式管理开销大)。由于无线接入技术多，非授权载波中将存在各种各样的无线***，彼此之间难于协调，干扰严重。因此，针对LTE部署在非授权载波中，仍然需要支持非授权载波的管制，多数国家要求***在非授权载波中部署时，需要支持先听后说(LBT)机制。通过先听后说机制可以避免相邻***之间同时使用非授权载波而为彼此带来的干扰。并且进一步引入竞争回退机制，即邻近的***站点(一般是同一***的邻近传输节点)，通过竞争回退机制后可以避免相同***的邻近传输节点同时使用非授权载波时带来的干扰。并且，管制中规定，使用非授权载波的设备(包括基站和用户设备(UE))在发送之前都是需要进行先听后说机制(即空闲信道评估(Clear Channel Assessment，简称CCA)，也称LBT机制)，当信道空闲时，设备才能使用非授权载波信道进行数据发送。In summary, although LTE deployment has obvious advantages in unlicensed carriers, there are still problems in the process of deployment; among them, there are many wireless access technologies (cross-communication standards, difficult collaboration, and diverse network topologies) ) and many wireless access sites (large number of users, difficult collaboration, centralized management overhead). Due to the large number of wireless access technologies, there will be various wireless systems in the unlicensed carrier, which are difficult to coordinate with each other and have serious interference. Therefore, for LTE deployed in unlicensed carriers, there is still a need to support the regulation of unlicensed carriers. Most countries require the system to support the Listen-Ahead (LBT) mechanism when deployed in unlicensed carriers. By listening to the mechanism first To avoid interference caused by the simultaneous use of unlicensed carriers between adjacent systems. And the competition back-off mechanism is further introduced, that is, the neighboring system sites (generally the neighboring transmission nodes of the same system) can avoid the interference caused by the neighboring transmission nodes of the same system simultaneously using the unlicensed carriers through the contention back-off mechanism. Moreover, the regulation stipulates that devices that use unlicensed carriers (including base stations and user equipments (UEs)) need to perform a listening and speaking mechanism (ie, Clear Channel Assessment (CCA), also called CSA). LBT mechanism), when the channel is idle, the device can use the unlicensed carrier channel for data transmission.

在LTE***中，会存在下面的问题：In the LTE system, the following problems exist:

如果基站调度多个用户设备UE计划在同一的上行子帧进行数据发送，此时UE如何执行CCA检测，以保证不同的UE能够同时成功为上行(UL)CCA检测，然后同时进行上行数据发送。If the base station schedules multiple user equipments to plan data transmission in the same uplink subframe, the UE performs CCA detection at this time to ensure that different UEs can successfully perform uplink (UL) CCA detection at the same time, and then simultaneously perform uplink data transmission.

另外，不同的UE之间如何保证竞争非授权载波的公平性，也是需要考虑的，例如，如果某一个UE总是竞争成功，连续多次完成数据发送，但是有些UE，基站多次为其发送上行授权信息，而这些UE由于UL CCA检测总是失败(CCA检测发现信道为忙)，不能按照基站调度要求来发送上行数据，并且基站侧还总是以为UE按照调度要求发送了上行数据，还继续执行接收和解码处理。显然，这个过程由于UL CCA失败导致了数据发送失败，上行授权浪费，基站增加了无效复杂度。这个问题应该如何解决或抑制呢？In addition, how to ensure the fairness of competing unlicensed carriers between different UEs is also considered. For example, if a UE always competes successfully, data transmission is performed multiple times in succession, but some UEs and base stations send them multiple times. Uplink authorization information, and these UEs always fail due to UL CCA detection (the CCA detects that the channel is busy), and cannot send uplink data according to the scheduling requirements of the base station, and the base station side always assumes that the UE sends uplink data according to the scheduling requirement, and The receiving and decoding processes are continued. Obviously, this process causes data transmission failure due to UL CCA failure, and the uplink authorization is wasted, and the base station increases the invalidity. How should this problem be solved or suppressed?

UE执行CCA检测的位置和具体CCA的形式也是需要进一步明确的，目前CCA的形式非常多，那么哪一种更适合UE呢？尤其是多个UE被调度复用在同一个上行子帧中时，如何使得多个UE在CCA成功后，在数据发送之前仍然保持占用信道，是UL CCA设计的关键点之一。The location where the UE performs CCA detection and the form of the specific CCA need to be further clarified. Currently, there are many forms of CCA, so which one is more suitable for the UE? In particular, when multiple UEs are scheduled to be multiplexed in the same uplink subframe, how to enable multiple UEs to remain occupied before the data is transmitted after the CCA is successful is one of the key points of the UL CCA design.

相关技术中，只有基站执行CCA的方案，基站和UE的数据发送特点不同，相关技术中进用户设备在对应的子帧上发送数据的一般流程为：UE先接收基站发送的上行授权信息，再去执行CCA，如果CCA检测成功才发送数据，否则不发送数据，且UE侧如果直接使用下行CCA的方法，则存在大概率CCA失败，导致UL LAA难以实现数据传输的问题。并且在竞争非授权载波时多个UE之间的公平性问题也是需要进行解决的。In the related art, only the base station performs the CCA scheme, and the data transmission characteristics of the base station and the UE are different. In the related art, the general process of the user equipment transmitting data in the corresponding subframe is: the UE first receives the uplink authorization information sent by the base station, and then Go to CCA, if the CCA test is successful The data is sent, otherwise the data is not sent, and if the UE side directly uses the downlink CCA method, there is a large probability that the CCA fails, which makes it difficult for the UL LAA to implement data transmission. And the fairness problem between multiple UEs when competing for unlicensed carriers also needs to be solved.

针对相关技术中的上述技术问题，目前尚未提出有效的解决方案。In view of the above technical problems in the related art, an effective solution has not yet been proposed.

步骤S102，确定用于进行上行CCA检测的子帧的时间段，其中，时间段的结束时刻点不晚于(早于或等于)子帧的用于发送上行数据的起始OFDM符号的起始边界；时间段的开始时刻点不早于(晚于或等于)用于发送上行数据的起始OFDM符号的前N个OFDM符号的起始边界；N为正整数；Step S102, determining a time period of a subframe for performing uplink CCA detection, where the end time point of the time segment is not later than (earlier than or equal to) the start of the start OFDM symbol for transmitting uplink data of the subframe. a boundary; a start time point of the time period is not earlier than (late or equal to) a start boundary of the first N OFDM symbols of the start OFDM symbol used for transmitting the uplink data; N is a positive integer;

步骤S104，在时间段内进行上行CCA检测。In step S104, uplink CCA detection is performed in a time period.

通过上述步骤，采用确定进行CCA检测的时间段，使得该时间段的结束时刻点不晚于子帧的用于发送上行数据的起始OFDM符号的起始边界，时间段的开始时刻点不早于用于发送上行数据的起始OFDM符号的前N个OFDM符号的起始边界，即使得当多个UE被调度复用在同一个子帧时，能够在该设定的时间段内进行CCA检测，进而多个UE都能够成功进行CCA检测，解决了相关技术中当多个UE被调度在同一个子帧进行数据发送时，UE如何执行CCA检测以保证不同的用户设备成功进行CCA检测的问题。 Through the above steps, the time period for determining the CCA detection is determined such that the end time point of the time period is not later than the start boundary of the start OFDM symbol of the subframe for transmitting the uplink data, and the start time of the time period is not early. The start boundary of the first N OFDM symbols of the start OFDM symbol used for transmitting the uplink data, that is, when a plurality of UEs are scheduled to be multiplexed in the same subframe, CCA detection can be performed within the set time period, In addition, multiple UEs can successfully perform CCA detection, which solves the problem of how the UE performs CCA detection to ensure that different user equipments successfully perform CCA detection when multiple UEs are scheduled to transmit data in the same subframe.

需要说明的是，上述子帧可以是上行子帧，也可以是特殊子帧，但并不限于此。上述上行数据可以包括物理上行共享信道(Physical Uplink Shared CHannel，简称为PUSCH)、物理随机接入信道(Physical Random Access CHannel，简称PRACH)、物理上行控制信道(Physical Uplink Control CHannel，简称PUCCH)、上行信道质量测量(SRS)中的一个或多个，但并不限于此。It should be noted that the foregoing subframe may be an uplink subframe or a special subframe, but is not limited thereto.

需要说明的是，在N为11或12时，子帧中的前3个OFDM符号用于发送下行数据，或子帧中的前3个OFDM符号用于发送下行数据，子帧的第4个符号至下一个子帧的第1个符号结束作为CCA检测时间段；在N为8或9时，子帧中的前6个OFDM符号用于发送下行数据或子帧中的前6个OFDM符号用于发送下行数据，子帧的第7个符号至下一个子帧的第1个符号结束作为CCA检测时间段；在N为5或6时，子帧中的前9个OFDM符号用于发送下行数据或子帧中的前9个OFDM符号用于发送下行数据，子帧的第10个符号至下一个子帧的第1个符号结束作为CCA检测时间段；在N为4或5时，子帧中的前10个OFDM符号或前3个OFDM符号用于发送下行数据；在N为3或4时，子帧中的前11个OFDM符号用于发送下行数据；在N为2或3时，子帧中的前12个OFDM符号用于发送下行数据；在N为1或2时，以下之一OFDM符号用于发送下行数据：子帧中的前6个OFDM符号、子帧中的前13个OFDM符号。It should be noted that when N is 11 or 12, the first 3 OFDM symbols in the subframe are used to transmit downlink data, or the first 3 OFDM symbols in the subframe are used to transmit downlink data, and the fourth subframe of the subframe. The symbol ends to the first symbol of the next subframe as the CCA detection period; when N is 8 or 9, the first 6 OFDM symbols in the subframe are used to transmit the downlink data or the first 6 OFDM symbols in the subframe. For transmitting downlink data, the 7th symbol of the subframe to the 1st symbol of the next subframe ends as the CCA detection period; when N is 5 or 6, the first 9 OFDM symbols in the subframe are used for sending The first 9 OFDM symbols in the downlink data or subframe are used to transmit downlink data, and the 10th symbol of the subframe to the 1st symbol of the next subframe ends as the CCA detection period; when N is 4 or 5, The first 10 OFDM symbols or the first 3 OFDM symbols in the subframe are used to transmit downlink data; when N is 3 or 4, the first 11 OFDM symbols in the subframe are used to transmit downlink data; at N is 2 or 3 The first 12 OFDM symbols in the subframe are used to transmit downlink data; when N is 1 or 2, one of the following OFDM symbols is used to send downlink data: The first six OFDM symbols, the front subframe 13 OFDM symbols.

具体地，在N为1，子帧中的前13个OFDM符号用于发送下行数据时，子帧中的第14个OFDM符号用于上行CCA检测。Specifically, when N is 1, and the first 13 OFDM symbols in the subframe are used to transmit downlink data, the 14th OFDM symbol in the subframe is used for uplink CCA detection.

需要说明的是，对于哪些OFDM符号可以用于发送上行数据，或者哪些OFDM符号可以用于发送下行数据，哪些OFDM符号可以用于进行CCA检测，根据用于发送上行数据的起始OFDM符号的不同而不同，需要说明的是，用于发送上行数据的起始OFDM符号可以是预先设定的。以N为11 为例进行说明，当上行数据起始符号为第8或第1个时，可以存在下面的方式：在用于发送上行数据的起始OFDM符号为子帧的第8个符号(对应符号7，子帧内符号的编号从0～13)时，该子帧的前3个OFDM符号用于发送下行数据，第4个至第7个OFDM中的某一时间点可以作为上述时间段的起始时间点，即第4个OFDM符号至第7个OFDM符号可以用于进行CCA检测，第8个OFDM符号至第14个OFDM可以用于发送上行数据；在用于发送上行数据的起始OFDM符号为子帧的第1个OFDM符号时，该子帧中的前3个OFDM符号用于发送下行数据，该子帧中的的第4个符号至第14个符号中的某一时间点可以作为上述时间段的起始时间点，即该子帧中的第4个OFDM符号至第14个OFDM符号可以用于进行CCA检测。上行数据从该子帧的下一个子帧的第1个符号开始发送。It should be noted that, for which OFDM symbols can be used to transmit uplink data, or which OFDM symbols can be used to transmit downlink data, which OFDM symbols can be used for CCA detection, according to different starting OFDM symbols used for transmitting uplink data Differently, it should be noted that the starting OFDM symbol used to transmit the uplink data may be preset. Take N as 11 For example, when the uplink data start symbol is the 8th or the 1st, the following manner may exist: the initial OFDM symbol used for transmitting the uplink data is the 8th symbol of the subframe (corresponding to the symbol 7, When the number of symbols in the sub-frame is from 0 to 13), the first three OFDM symbols of the subframe are used to transmit downlink data, and a certain time point in the fourth to seventh OFDM may be used as the start of the time period. The time points, ie, the 4th OFDM symbol to the 7th OFDM symbol may be used for CCA detection, the 8th OFDM symbol to the 14th OFDM may be used for transmitting uplink data; and the initial OFDM symbol used for transmitting uplink data When the first OFDM symbol of the subframe is used, the first three OFDM symbols in the subframe are used to transmit downlink data, and a certain time point from the fourth symbol to the 14th symbol in the subframe may be used as The starting time point of the above time period, that is, the 4th OFDM symbol to the 14th OFDM symbol in the subframe may be used for CCA detection. The uplink data is transmitted starting from the first symbol of the next subframe of the subframe.

在N为12的时候，对应一种实施例，即对应允许上行数据从第2个符号开始发送。当前子帧的前3个符号用于发送下行数据，当前子帧的第4个符号至下一个子帧的第1个符号中的某一时间点作为上述时间段的起始时间点。上行数据从所述下一个子帧的第2个符号开始发送。When N is 12, corresponding to an embodiment, corresponding to allowing uplink data to be transmitted from the second symbol. The first three symbols of the current subframe are used to transmit downlink data, and a certain time point in the first symbol of the current subframe to the first symbol of the next subframe is used as the starting time point of the time period. The uplink data is transmitted starting from the second symbol of the next subframe.

在本公开的一个实施例中，在步骤S104之前，上述方法还可以包括：根据上行CCA的等级确定上行CCA检测的时长；其中，上行CCA的等级越高，确定的上行CCA检测的时长越长。上述步骤S104可以表现为：在上行CCA检测的时长所指示的时间内进行上行CCA检测。In an embodiment of the present disclosure, before the step S104, the method may further include: determining a duration of the uplink CCA detection according to the level of the uplink CCA; wherein, the higher the level of the uplink CCA, the longer the determined duration of the uplink CCA detection. . The above step S104 can be performed by performing uplink CCA detection in the time indicated by the duration of the uplink CCA detection.

需要说明的是，可以通过以下至少之一参数确定上行CCA的等级：9微秒的个数m、调度或计划发送的时长、CCA次数；其中，CCA次数在上行CCA检测之前或之前的一段时间内，终端执行上行CCA检测失败导致被调度的上行数据不能发送的次数；其中，所述调度或计划发送的时长为终端发送上行数据的连续上行子帧数。It should be noted that the level of the uplink CCA may be determined by at least one of the following parameters: the number of 9 microseconds, the duration of scheduling or scheduled transmission, and the number of CCAs; wherein, the number of CCAs is before or before the uplink CCA detection. If the terminal performs the uplink CCA detection failure, the number of times that the scheduled uplink data cannot be sent; wherein the duration of the scheduling or scheduled transmission is the number of consecutive uplink subframes in which the terminal sends the uplink data.

需要说明的是，上述终端发送上行数据的连续上行子帧数可以是基站告知终端的，比如基站在向终端发送调度信息时，同时告知终端在哪些上行子帧上发送数据，而这些上行子帧中连续上行子帧数即为上述终端发送上行数据的连续上行子帧数。It should be noted that the number of consecutive uplink subframes in which the terminal sends uplink data may be a base station. Informing the terminal, for example, when the base station sends the scheduling information to the terminal, the base station simultaneously informs the terminal of the uplink subframes, and the number of consecutive uplink subframes in the uplink subframe is the number of consecutive uplink subframes in which the terminal sends the uplink data. .

可以通过调度或计划发送的时长一个参数来确定上行CCA的等级，也可以通过调度或计划发送的时长结合其他参数来确定上行CCA的等级，对于前者，具体可以表现为：根据调度或计划发送的时长按照第一映射关系找到与调度或计划发送的时长对应的上行CCA的等级，将与调度或计划发送的时长对应的上行CCA的等级确定为上行CCA的等级；其中，第一映射关系为调度或计划发送的时长与上行CCA的等级的映射关系。对于后者可以表现为以下形式，但并不限于此：在与调度或计划发送的时长对应多个上行CCA的等级的情况下，根据调度或计划发送的时长按照第一映射关系找到与调度或计划发送的时长对应的上行CCA的等级之后，再根据待传输的业务等级或QoS等级，从与调度或计划发送的时长对应的多个上行CCA的等级中确定上行CCA的等级。或者，在与调度或计划发送的时长对应多个上行CCA的等级的情况下，根据调度或计划发送的时长按照第一映射关系找到与调度或计划发送的时长对应的上行CCA的等级之后，根据CCA次数，按照第二映射关系从与调度或计划发送的时长对应的多个上行CCA的等级中确定出上行CCA的等级；其中，第二映射关系为CCA次数与上行CCA的等级的映射关系。The level of the uplink CCA may be determined by a parameter of the duration of the scheduling or planned transmission, and the level of the uplink CCA may be determined by scheduling or scheduling the duration of the transmission, in combination with other parameters, for the former, the specific performance may be: according to the schedule or plan. The duration of the uplink CCA corresponding to the duration of the scheduled or planned transmission is found according to the first mapping relationship, and the level of the uplink CCA corresponding to the duration of the scheduled or planned transmission is determined as the level of the uplink CCA; wherein the first mapping relationship is the scheduling Or the mapping relationship between the planned transmission duration and the level of the uplink CCA. The latter may be expressed in the following form, but is not limited to this: in the case of a plurality of uplink CCA levels corresponding to the duration of the scheduling or scheduled transmission, the scheduling or the scheduled transmission time is found according to the first mapping relationship and scheduling or After the level of the uplink CCA corresponding to the duration of the scheduled transmission, the level of the uplink CCA is determined from the levels of the plurality of uplink CCAs corresponding to the duration of the scheduled or planned transmission according to the service level or QoS level to be transmitted. Or, if the level of the uplink CCA corresponding to the duration of the scheduling or the planned transmission is found according to the duration of the scheduling or the planned transmission, according to the duration of the scheduled or scheduled transmission, according to the duration of the scheduling or the scheduled transmission, according to the first mapping relationship, The CCA number determines the level of the uplink CCA from the levels of the plurality of uplink CCAs corresponding to the duration of the scheduled or planned transmission according to the second mapping relationship; wherein the second mapping relationship is a mapping relationship between the number of CCAs and the level of the uplink CCA.

根据CCA次数，按照第二映射关系从与调度或计划发送的时长对应的多个上行CCA的等级中确定出上行CCA的等级可以表现为：当按照第二映射关系在多个上行CCA的等级所对应的CCA次数中找到CCA次数的情况下，将多个上行CCA的等级中与CCA次数对应的上行CCA的等级确定为上行CCA的等级；在与调度或计划发送的时长对应多个上行CCA的等级的情况下，当按照第二映射关系在多个上行CCA的等级所对应的CCA 次数中未找到CCA次数的情况下，将多个上行CCA的等级中等级最高的上行CCA的等级所对应的CCA次数作为门限，在CCA次数小于门限的情况下，确定多个上行CCA的等级中的等级最低的上行CCA的等级为上行CCA的等级；在CCA次数大于门限的情况下，确定多个上行CCA的等级中的等级最高的上行CCA的等级为上行CCA的等级。According to the number of CCAs, determining, according to the second mapping relationship, the level of the uplink CCA from the levels of the plurality of uplink CCAs corresponding to the duration of the scheduled or scheduled transmission may be expressed as: when the levels of the multiple uplink CCAs are in accordance with the second mapping relationship. When the number of CCAs is found in the corresponding number of CCAs, the level of the uplink CCA corresponding to the number of CCAs among the levels of the plurality of uplink CCAs is determined as the level of the uplink CCA; and the number of uplink CCAs corresponding to the duration of the scheduling or planned transmission is determined. In the case of a level, when the CCA corresponding to the level of the plurality of uplink CCAs according to the second mapping relationship If the number of CCAs is not found in the number of times, the number of CCAs corresponding to the level of the highest CCA of the highest level of the plurality of uplink CCAs is used as a threshold, and when the number of CCAs is less than the threshold, the level of the plurality of uplink CCAs is determined. The lowest level of the uplink CCA is the level of the uplink CCA; when the number of CCAs is greater than the threshold, it is determined that the level of the highest CCA of the highest level of the plurality of uplink CCAs is the level of the uplink CCA.

对于调度或计划发送的时长结合9微秒来确定上行CCA的等级的方案，可以是先按照上述第一映射关系来确定上行CCA的等级，然后再根据9微秒的个数与上行CCA的等级的映射关系进一步确定上行CCA的等级，此处不再详细赘述。另外，需要说明的是，也可以单独根据CCA的次数按照上述第二映射关系来确定上行CCA的等级，也可以在根据CCA的次数按照上述第二映射关系来确定上行CCA的等级之后，再根据9微秒的个数与上行CCA的等级的映射关系进一步确定上行CCA的等级；当然单独根据9微秒的个数依据9微秒的个数与上行CCA的等级的映射关系也可以确定上行CCA的等级，或者三个参数互相结合来确定上述CCA的等级。For the scheme of determining the level of the uplink CCA by combining the duration of the scheduling or the scheduled transmission, the level of the uplink CCA may be determined according to the first mapping relationship, and then the number of the uplink CCA is determined according to the number of 9 microseconds. The mapping relationship further determines the level of the uplink CCA, which will not be described in detail herein. In addition, it should be noted that the level of the uplink CCA may be determined according to the second mapping relationship according to the number of times of the CCA, or may be determined according to the second mapping relationship according to the number of times of the CCA, and then according to the second mapping relationship. The mapping relationship between the number of 9 microseconds and the level of the uplink CCA further determines the level of the uplink CCA; of course, the uplink CCA can also be determined according to the mapping of the number of 9 microseconds to the level of the uplink CCA according to the number of 9 microseconds. The level, or three parameters, are combined with each other to determine the level of the above CCA.

上述第一映射关系可以包括以下之一子映射关系，但并不限于此：第一子映射关系：在调度或计划发送的时长为1毫秒时，上行CCA的等级为1或2；在调度或计划发送的时长为2毫秒时，上行CCA的等级为3；在调度或计划发送的时长为3毫秒时，上行CCA的等级为4；在调度或计划发送的时长为4毫秒时，上行CCA的等级为5；在调度或计划发送的时长为大于4毫秒时，上行CCA的等级为6；第二子映射关系：在调度或计划发送的时长为1毫秒时，上行CCA的等级为1；在调度或计划发送的时长属于2毫秒至3毫秒所示的范围时，上行CCA的等级为2；在调度或计划发送的时长为4毫秒以上时，上行CCA的等级为3。The first mapping relationship may include one of the following sub-map relationships, but is not limited thereto: the first sub-map relationship: when the duration of scheduling or scheduled transmission is 1 millisecond, the level of the uplink CCA is 1 or 2; When the planned transmission time is 2 milliseconds, the uplink CCA level is 3; when the scheduled or scheduled transmission time is 3 milliseconds, the uplink CCA level is 4; when the scheduled or scheduled transmission time is 4 milliseconds, the uplink CCA is The level is 5; when the duration of scheduling or scheduled transmission is greater than 4 milliseconds, the level of the uplink CCA is 6; the second sub-map relationship: when the duration of scheduling or scheduled transmission is 1 millisecond, the level of the uplink CCA is 1; When the duration of scheduling or scheduled transmission belongs to the range indicated by 2 milliseconds to 3 milliseconds, the level of the uplink CCA is 2; when the duration of scheduling or scheduled transmission is 4 milliseconds or longer, the level of the uplink CCA is 3.

上述第二映射关系可以包括以下之一子映射关系，但并不限于此：第三子映射关系：在CCA次数大于4次时，上行CCA的等级为1；在CCA 次数为4次时，上行CCA的等级为2；在CCA次数为3次时，上行CCA的等级为3；在CCA次数为2次时，上行CCA的等级为4；在CCA次数为1次时，上行CCA的等级为5；在CCA次数为0次时，上行CCA的等级为6；第四子映射关系：在CCA次数大于2次时，上行CCA的等级为1；在CCA次数为2次时，上行CCA的等级为2；在CCA次数为1次时，上行CCA的等级为3；在CCA次数为0次时，上行CCA的等级为4；第五子映射关系：在CCA次数大于1次时，上行CCA的等级为1；在CCA次数为1次时，上行CCA的等级为2；在CCA次数为0次时，上行CCA的等级为3。The foregoing second mapping relationship may include one of the following sub-map relationships, but is not limited thereto: the third sub-map relationship: when the number of CCAs is greater than 4 times, the level of the uplink CCA is 1; in the CCA When the number of times is 4, the level of the uplink CCA is 2; when the number of CCA is 3, the level of the uplink CCA is 3; when the number of CCA is 2, the level of the uplink CCA is 4; when the number of CCA is 1 The level of the uplink CCA is 5; when the number of CCAs is 0, the level of the uplink CCA is 6; the fourth sub-map relationship: when the number of CCAs is greater than 2 times, the level of the uplink CCA is 1; the number of times of the CCA is 2 times The level of the uplink CCA is 2; when the number of CCA is 1 time, the level of the uplink CCA is 3; when the number of CCA times is 0, the level of the uplink CCA is 4; the fifth sub-map relationship: the number of times of the CCA is greater than 1 The next time, the level of the uplink CCA is 1; when the number of CCA is 1 time, the level of the uplink CCA is 2; when the number of CCA times is 0, the level of the uplink CCA is 3.

需要说明的是，上行CCA的等级的取值越小，上行CCA的等级越高。It should be noted that the smaller the value of the level of the uplink CCA is, the higher the level of the uplink CCA is.

在本公开实施例中，上行CCA检测的时长的取值包括以下至少之一：上行CCA检测的时长为16微秒和m个9微秒之和，其中，m为自然数；上行CCA检测的时长为以下至少之一：25微秒、34微秒、43微秒、52微秒、61微秒、70微秒；上行CCA检测的时长由K个固定时长组成，其中，固定时长用于一个CCA检测，固定时长为以下之一：16微秒、25微秒、34微秒、43微秒；K为正整数。In the embodiment of the present disclosure, the value of the duration of the uplink CCA detection includes at least one of the following: the duration of the uplink CCA detection is 16 microseconds and m 9 microseconds, where m is a natural number; the duration of the uplink CCA detection. At least one of: 25 microseconds, 34 microseconds, 43 microseconds, 52 microseconds, 61 microseconds, 70 microseconds; the duration of the uplink CCA detection is composed of K fixed durations, wherein the fixed duration is used for one CCA Detection, the fixed duration is one of the following: 16 microseconds, 25 microseconds, 34 microseconds, 43 microseconds; K is a positive integer.

在本公开实施例中，上行CCA检测的时长所指示的时间的开始时刻点为将时间段的结束时间点减去上行CCA检测的时长得到的时间点。即通过将上行CCA检测的时长所指示的时间的结束时刻点固定，即当多个UE进行CCA检测时，保证多个用UE的CCA检测的结束时刻点相同，进而避免了不同UE由于竞争的非公平性导致的UE之间的相互干扰问题。In the embodiment of the present disclosure, the start time point of the time indicated by the duration of the uplink CCA detection is a time point obtained by subtracting the time length of the uplink CCA detection from the end time point of the time period. That is, by fixing the end time point of the time indicated by the duration of the uplink CCA detection, that is, when multiple UEs perform CCA detection, it is ensured that the end time points of the CCA detection of multiple UEs are the same, thereby avoiding competition of different UEs. Mutual interference problems between UEs caused by unfairness.

需要说明的是，上述上行CCA检测的时长可以用于一次上行CCA检测，也可以用于多次上行CCA检测，比如在上行CCA检测的时长由K个固定时长组成的情况下，上行CCA检测的时长为用于进行K次上行CCA检测所用的时长；其中，每一次上行CCA检测所用的时长为固定时长。 It should be noted that the duration of the uplink CCA detection may be used for one uplink CCA detection, and may also be used for multiple uplink CCA detections. For example, when the duration of the uplink CCA detection is composed of K fixed durations, the uplink CCA detection is performed. The duration is the duration used for performing K times of uplink CCA detection; wherein the duration of each uplink CCA detection is a fixed duration.

需要说明的是，可以通过以下至少之一方式确定上述K：接收基站预先配置的K；根据上一次上行CCA检测是否成功来确定K；其中，在上一次上行CCA检测失败的情况下，K为上一次的K值减Q；在一次上行CCA检测成功的情况下，K为上一次的K值加Q；其中，Q为正整数。It should be noted that the K may be determined by at least one of the following: the K that is preset by the receiving base station; and the K determined according to whether the last uplink CCA detection is successful; wherein, in the case that the last uplink CCA detection fails, K is The last K value is reduced by Q; in the case where an uplink CCA detection is successful, K is the last K value plus Q; where Q is a positive integer.

需要说明的是，上述K值却大，那么上行CCA检测的时长就会越长，那么对应的CCA的等级就会越高。It should be noted that if the above K value is large, the longer the duration of the uplink CCA detection, the higher the level of the corresponding CCA.

在本公开的一个实施例中，上述步骤S104之后，上述方法还可以包括：在保持信道空闲的时长达到上行CCA检测的时长之后，在上行子帧上发送上行数据。即在多个UE CCA检测成功后，在上行数据发送之前，保持仍然占用信道。In an embodiment of the present disclosure, after the step S104, the method may further include: sending uplink data on the uplink subframe after the duration of the channel idle period reaches the duration of the uplink CCA detection. That is, after multiple UE CCAs are successfully detected, the channel is still occupied before the uplink data is transmitted.

需要说明的是，可以通过以下方式来获取上行CCA的等级：方式一，UE根据基站发送的下行调度的子帧数量，再结合UE根据最近的UE执行CCA失败导致上行传输失败的次数(即CCA次数)来确定UE上行CCA的优先级或执行的时长；方式二，UE接收基站发送的上行CCA等级，可选的，UE再结合UE统计的CCA失败次数，根据约定的规则进一步调整上行CCA的等级；方式三，基站根据多子帧调度的子帧数量和CCA失败次数为UE配置上行CCA的等级或执行的时长；其中，CCA失败次数为UE上报给基站，或基站统计获得。其中，UE通过专用RRC消息或上行控制指示(UCI)上报CCA失败次数；具体地，基站统计获得可以具体表现为：基站在调度UE发送上行数据的子帧中尝试接收UE发送的数据，如果基站不能确定UE是否由于CCA失败未发送上行数据时，基站一旦解码错误则认为是UE上行CCA失败。It should be noted that the level of the uplink CCA can be obtained in the following manner: mode 1, the number of subframes scheduled by the UE according to the downlink scheduling, and the number of times the UE fails to perform uplink transmission according to the latest UE performing CCA failure (ie, CCA) The number of times to determine the priority or duration of the uplink CCA of the UE. In the second method, the UE receives the uplink CCA level sent by the base station. Optionally, the UE combines the number of CCA failures calculated by the UE with the UE, and further adjusts the uplink CCA according to the agreed rules. Level 3: The base station configures the level of the uplink CCA or the duration of the execution according to the number of subframes and the number of CCA failures scheduled by the multiple subframes. The number of CCA failures is reported to the UE by the UE, or the base station obtains statistics. The UE may report the number of CCA failures by using a dedicated RRC message or an uplink control indication (UCI). Specifically, the base station statistics obtaining may be specifically performed by: the base station attempts to receive data sent by the UE in a subframe in which the scheduling UE sends uplink data, if the base station If it is not determined whether the UE does not send uplink data due to CCA failure, the base station considers that the UE uplink CCA fails once it is decoded incorrectly.

通过上述方法，可以获得下列益处：为UE执行上行CCA提供准确的时域执行区间，设置上行CCA等级和长度，可以调整不同UE由于附近信道环境带来的抢占信道概率不公平问题。 Through the foregoing method, the following benefits can be obtained: providing an accurate time domain execution interval for the UE to perform uplink CCA, setting an uplink CCA level and length, and adjusting an unfairness of preemptive channel probability caused by different channel environments of different UEs.

为了更好地理解本公开，以下结合具体的实施例对本公开做进一步地解释。For a better understanding of the present disclosure, the present disclosure is further explained below in conjunction with the specific embodiments.

实施例1Example 1

设置上行CCA的等级与下面的参数有关：多子帧调度的子帧数量。Setting the level of the uplink CCA is related to the following parameters: the number of subframes scheduled for multiple subframes.

具体地，基站调度UE或UE自主决定连续发送多于一个子帧(一个子帧为1ms，时长和子帧数可以互换)时，此时UE就属于采用多子帧调度的机制发送数据，其中连续调度的子帧数可能为2、3、4等，考虑到实际情况下，每次传输最大占用的子帧最多为10ms(这是授权辅助接入(LAA)下行的要求，地区管制中是13ms)。Specifically, when the base station schedules the UE or the UE autonomously determines to continuously transmit more than one subframe (one subframe is 1 ms, and the duration and the number of subframes are interchangeable), the UE belongs to the mechanism that uses multi-subframe scheduling to send data, where The number of consecutively scheduled subframes may be 2, 3, 4, etc. Considering the actual situation, the maximum occupied subframe for each transmission is at most 10 ms (this is the requirement for Authorized Auxiliary Access (LAA) downlink, and the regional control is 13ms).

如果UE发送子帧数为1个子帧，则UE发送数据之前信道至少空闲25μs。If the number of subframes transmitted by the UE is 1 subframe, the channel is at least 25 μs idle before the UE transmits data.

如果UE被配置多子帧调度，例如连续3个子帧，但是UE在为前2个子帧执行CCA检测时，信道为忙，对于最后一个子帧时，UE也是在发送数据之前信道至少空闲25μs即可。If the UE is configured with multiple subframe scheduling, for example, 3 consecutive subframes, but the UE performs busy CCA detection for the first 2 subframes, the channel is busy. For the last subframe, the UE is also at least 25 μs idle before transmitting data. can.

Td的时长是指LTE协议36.213vd00中定义的。Td由16μs和m个9μs组成。The duration of Td is defined in the LTE protocol 36.213vd00. Td consists of 16 μs and m 9 μs.

基站按照表1或表2或表3设置CCA检测时长与对应的发送时长。等级越高，对应的CCA检测时长越短，发送的时长越短。对于窗长的使用可以参考现有技术中为下行PDSCH信道发送而执行的CCA检测中的随机竞争窗的窗长的使用，其使用方法与现有技术中的方法是相同的。CCA制式为单次CCA，或者带有竞争窗的CCA。The base station sets the CCA detection duration and the corresponding transmission duration according to Table 1 or Table 2 or Table 3. The higher the level, the shorter the corresponding CCA detection duration and the shorter the transmission duration. For the use of the window length, reference may be made to the use of the window length of the random contention window in the CCA detection performed in the prior art for downlink PDSCH channel transmission, which is used in the same manner as in the prior art. The CCA standard is a single CCA, or a CCA with a competitive window.

表1Table 1

表2Table 2

表3table 3

下面以表1为例描述：The following is an example of Table 1:

当UE计划或者被基站调度发送时长为1ms时，UE可以选择执行等级为1或2的CCA等级。等级1检测的时长最短，所以对应最高优先级别的业务，其次是等级2。也就是说，对于计划发送时长为1ms时，UE还需要结合待传输的业务等级或QoS等级进一步确定选择等级1还是2。例如UE发送PRACH序列时，可以使用等级1。传输PUCCH时可以使用等级2。When the UE schedules or is scheduled to be transmitted by the base station for 1 ms, the UE may select to perform a CCA level of level 1 or 2. The level 1 detection has the shortest duration, so it corresponds to the highest priority level of service, followed by level 2. That is to say, when the planned transmission duration is 1 ms, the UE further needs to determine the selection level 1 or 2 in combination with the service level or QoS level to be transmitted. For example, when the UE transmits a PRACH sequence, level 1 can be used. Level 2 can be used when transmitting PUCCH.

当UE计划或者被基站调度发送时长为2ms时，此时UE执行的等级3。具体为：UE先执行信道空闲25μs，之后随机产生递减的N值，N的取值范围为0～3(3来自{3,4}，对应等级3中，N的最小取值范围，其他等级依次类推)，或者0～4(4来自{3,4}，对应等级3中，N的最大取值范围，其他等级依次类推)。N的递减规则可以参考LTE协议36.213vd00。When the UE plans or is scheduled to be transmitted by the base station for 2 ms, the UE performs level 3 at this time. Specifically, the UE performs channel idle for 25 μs first, and then randomly generates a decreasing value of N. The value of N ranges from 0 to 3 (3 is from {3, 4}, corresponding to level 3, the minimum value range of N, and other levels. And so on), or 0 to 4 (4 from {3, 4}, corresponding to level 3, the maximum value range of N, and so on by other levels). The decrement rule of N can refer to the LTE protocol 36.213vd00.

当使用某一等级中N的最大取值范围产生N值进行CCA检测为获得非授权载波使用权时，如果连续K1次都不能成功，则使用该等级中N的最小取值范围产生N值进行CCA检测。优选的，K1取值范围为{1，2，…，8}。When the maximum value range of N in a certain level is used to generate an N value for CCA detection to obtain the unlicensed carrier usage right, if the continuous K1 times cannot be successful, the minimum value range of N in the level is used to generate the N value for CCA. Detection. Preferably, K1 ranges from {1, 2, ..., 8}.

如果使用某一等级中N的最小取值范围产生N值进行CCA检测为获得非授权载波使用权时，如果连续K2次都不能成功，则使用上一个等级中N的最大取值范围产生N值进行CCA检测。优选的，K2取值范围为{2，3，…，8}。If the minimum value range of N in a certain level is used to generate the N value for CCA detection to obtain the unlicensed carrier usage right, if the continuous K2 times cannot be successful, the maximum value range of N in the previous level is used to generate the N value. CCA testing. Preferably, K2 ranges from {2, 3, ..., 8}.

实施例2Example 2

设置CCA等级依据UE执行CCA失败(未发现信道空闲)导致被调度的数据发送失败的次数(记为CCA次数)。The CCA level is set according to the number of times the UE fails to perform CCA failure (no channel idle is found), causing the scheduled data transmission failure (denoted as the number of CCAs).

表4、表5和表6给出了与等级相关的设置。下面以表格4为例说明如何使用。 Tables, Tables 5 and 6 give the level-related settings. Table 4 is used as an example to illustrate how to use it.

当设备连续使用基站配置的CCA机制或者根据约定规则选取的CCA机制或等级，进行信道检测时，CCA检测的结果：如果连续出现多次CCA检测均发现信道为非空闲，设备不能发送被调度的数据，则设备依据表1中CCA失败次数，选择下一次CCA检测的机制或等级。When the device continuously uses the CCA mechanism configured by the base station or the CCA mechanism or level selected according to the agreed rules to perform channel detection, the result of the CCA detection is: if multiple consecutive CCA detections are found that the channel is not idle, the device cannot send the scheduled Data, the device selects the mechanism or level of the next CCA detection according to the number of CCA failures in Table 1.

表4Table 4

表5table 5

表6Table 6

实施例3Example 3

设置CCA等级按照下面的表7、表8或表9。具体的使用如下，以表7为例进行说明。Set the CCA level according to Table 7, Table 8, or Table 9 below. The specific use is as follows, and Table 7 is taken as an example for explanation.

基站按照调度或计划发送的时长以及CCA次数确定CCA等级。等级越高，对应的CCA检测时长越短，发送的时长越短。其中调度或计划发送的时长优先级高于CCA次数。The base station determines the CCA level according to the duration of the scheduling or planned transmission and the number of CCAs. The higher the level, the shorter the corresponding CCA detection duration and the shorter the transmission duration. The duration of scheduling or scheduled transmission is higher than the number of CCAs.

例如当调度发送时长为1ms时，此时对应等级1、2，设备再依据CCA次数进一步选择，如果设备的CCA次数大于4则选择等级1，否则选择等级2。For example, when the scheduling transmission duration is 1 ms, corresponding to the level 1 and 2, the device further selects according to the number of CCAs. If the number of CCAs of the device is greater than 4, the level 1 is selected, otherwise the level 2 is selected.

表7Table 7

表8Table 8

表9Table 9

表9中当设备调度发送的时长为2ms～3ms时，此时候选等级有2、3，设备加入此时CCA次数为1，并不是2或3，这种情况，按照等级较高者的CCA次数为划分门限，例如此时按照等级2的CCA次数3划分门限，由于设备实际CCA次数为1，小于门限3，那么设备选择较低等级，此时为等级3。如果设备实际CCA次数为3，那么大于等于门限3，那么设备选择较高等级，此时为等级2。In Table 9, when the duration of the device scheduling transmission is 2ms to 3ms, the candidate level is 2 and 3, and the number of CCAs at the time of device join is 1, not 2 or 3. In this case, the CCA according to the higher rank. The number of times is the division threshold. For example, the threshold is divided according to the number of CCAs of level 2 at this time. Since the actual number of CCAs of the device is 1, less than the threshold 3, the device selects a lower level, and this is level 3. If the actual number of CCAs of the device is 3, then the threshold is greater than or equal to 3, then the device selects a higher level, which is level 2.

Taking N as an example for example, when the uplink data start symbol is the 8th or the 1st, the following manner may exist: the first OFDM symbol used for transmitting the uplink data is the 8th symbol of the subframe ( Corresponding to symbol 7, when the number of symbols in the sub-frame is from 0 to 13), the first three OFDM symbols of the subframe are used to transmit downlink data, and a certain time point in the fourth to seventh OFDM may be used as the time. The start time point of the segment, that is, the 4th OFDM symbol to the 7th OFDM symbol may be used for CCA detection, and the 8th OFDM symbol to the 14th OFDM may be used for transmitting uplink data; When the first OFDM symbol is the first OFDM symbol of the subframe, the first three OFDM symbols in the subframe are used to transmit downlink data, and one of the fourth symbol to the 14th symbol in the subframe The time point can be used as the starting time point of the above time period, that is, the 4th OFDM symbol to the 14th OFDM symbol in the subframe can be used for CCA detection. The uplink data is transmitted starting from the first symbol of the next subframe of the subframe.

在N为12的时候，对应一种实施例，即对应允许上行数据从第2个符号开始发送。当前子帧的前3个符号用于发送下行数据，当前子帧的第4 个符号至下一个子帧的第1个符号中的某一时间点作为上述时间段的起始时间点。上行数据从所述下一个子帧的第2个符号开始发送。When N is 12, corresponding to an embodiment, corresponding to allowing uplink data to be transmitted from the second symbol.
