Description

一种上行控制信息发送方法、设备和信令A method, device and signaling for sending uplink control information

技术领域technical field

本申请涉及移动通信技术领域,尤其涉及一种上行控制信息发送的方法和设备。The present application relates to the field of mobile communication technologies, and in particular, to a method and device for sending uplink control information.

背景技术Background technique

5G已成为移动通信的最新一代技术,一个重要应用就是在非授权频段的使用。在非授权频段,需要考虑各种无线系统共存。典型的非授权频段应用包括Wifi、基于LTE的LAA技术等。为了使多种技术共存,各国监管机构对非授权频段的使用采用强制的先听后发技术(LBT),即只有当侦听到目前信道没有被占用时才能进行数据发送。这种机制带来的问题是有些数据不能保证在确定的位置发送。如果现有的5G新空口设计(NR)直接用于非授权频段,性能很难得到保证。尤其是基于5G NR的设计在非授权频段独立部署时,由于反馈信息不能保证在固定时间及时发送,在业务比较繁忙的时候,系统性能将大幅度下降。5G has become the latest generation of mobile communication technology, and an important application is the use of unlicensed frequency bands. In unlicensed bands, the coexistence of various wireless systems needs to be considered. Typical unlicensed band applications include Wifi, LTE-based LAA technology, etc. In order to allow multiple technologies to coexist, regulatory agencies in various countries adopt the mandatory listen-before-transmit (LBT) technique for the use of unlicensed frequency bands, that is, data transmission can only be performed when it is detected that the current channel is not occupied. The problem with this mechanism is that some data is not guaranteed to be sent in a certain location. If the existing 5G new radio interface design (NR) is directly used in the unlicensed frequency band, the performance can hardly be guaranteed. Especially when the 5G NR-based design is independently deployed in the unlicensed frequency band, since the feedback information cannot be guaranteed to be sent at a fixed time, the system performance will be greatly reduced when the business is busy.

根据5G NR在非授权频段的使用,其设计需要支持多种场景,尤其要在非授权频段需要独立进行部署。为支持在非授权频段能独立部署,终端设备(UE)需要在非授权频段进行上行控制信道(PUCCH)发送。根据目前标准的规定,PUCCH的发送需要通过网络设备(gNB)进行配置,然后终端根据gNB配置的PUCCH资源进行相应的上行控制信息发送。According to the use of 5G NR in unlicensed frequency bands, its design needs to support multiple scenarios, especially in unlicensed frequency bands, it needs to be deployed independently. In order to support independent deployment in the unlicensed frequency band, the terminal equipment (UE) needs to transmit the uplink control channel (PUCCH) in the unlicensed frequency band. According to the current standard, the transmission of PUCCH needs to be configured by a network device (gNB), and then the terminal sends corresponding uplink control information according to the PUCCH resources configured by the gNB.

根据目前标准规定,gNB配置的PUCCH配置发送位置固定。由于在非授权频段数据发送需要满足LBT的要求,一旦由于LBT导致指示时间不能发送PUCCH,那么UE在非授权频段性数据发送将受到很大影响。本发明提供一种的PUCCH配置方式。通过该方式,可以增加一个PUCCH配置可用的资源数量,提升PUCCH的鲁棒性,从而提升NR在非授权频段的性能。According to the current standard, the PUCCH configuration configured by the gNB has a fixed transmission position. Since data transmission in the unlicensed frequency band needs to meet the requirements of LBT, once the PUCCH cannot be transmitted due to the indicated time due to LBT, the data transmission of the UE in the unlicensed frequency band will be greatly affected. The present invention provides a PUCCH configuration method. In this way, the number of resources available for a PUCCH configuration can be increased, the robustness of the PUCCH can be improved, and the performance of NR in the unlicensed frequency band can be improved.

具体实施方式Detailed ways

为使本申请的目的、技术方案和优点更加清楚,下面将结合本申请具体实施例及相应的附图对本申请技术方案进行清楚、完整地描述。显然,所描述的实施例仅是本申请一部分实施例,而不是全部的实施例。基于本申请中的实施例,本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例,都属于本申请保护的范围。In order to make the objectives, technical solutions and advantages of the present application clearer, the technical solutions of the present application will be clearly and completely described below with reference to the specific embodiments of the present application and the corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of the present application, but not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

根据目前NR协议,UE发送PUCCH基本流程为:According to the current NR protocol, the basic process of UE sending PUCCH is as follows:

gNB通知UE可用PUCCH发送资源;The gNB informs the UE that the PUCCH transmission resources are available;

UE根据发送信息类型及大小,结合gNB配置的PUCCH发送资源,确定PUCCH发送内容、格式及发送位置,然后进行PUCCH发送;The UE determines the content, format and transmission position of the PUCCH according to the type and size of the transmission information, combined with the PUCCH transmission resources configured by the gNB, and then transmits the PUCCH;

gNB在配置的PUCCH资源处进行PUCCH的检测和接收。The gNB performs PUCCH detection and reception at the configured PUCCH resources.

根据目前标准方案,gNB通知UE的PUCCH发送资源配置只含有一个发送时间点。非授权频段由于有其他系统共存,存在该配置时间点受到干扰而不能发送PUCCH的情况。According to the current standard solution, the PUCCH transmission resource configuration notified by the gNB to the UE only contains one transmission time point. Due to the coexistence of other systems in the unlicensed frequency band, there is a situation where the configuration time point is interfered and the PUCCH cannot be sent.

为了提升PUCCH发送鲁棒性,本发明提供一种在非授权频段PUCCH的配置方式。In order to improve the robustness of PUCCH transmission, the present invention provides a configuration method of PUCCH in an unlicensed frequency band.

以下结合附图,详细说明本申请各实施例提供的技术方案。The technical solutions provided by the embodiments of the present application will be described in detail below with reference to the accompanying drawings.

图1为PUCCH资源配置参数示意图。根据目前标准TS38.331规定,PUCCH的发送需要根据gNB的配置,其中PUCCH资源具体配置参数为PUCCH-Resource。PUCCH-Resource配置包括配置标号(pucch-ResourceId)、频率开始位置(startingPRB)、是否采用跳频、PUCCH格式等信息(format),具体配置见图1。FIG. 1 is a schematic diagram of PUCCH resource configuration parameters. According to the current standard TS38.331, the transmission of the PUCCH needs to be configured according to the gNB, and the specific configuration parameter of the PUCCH resource is PUCCH-Resource. The PUCCH-Resource configuration includes information (format) such as a configuration label (pucch-ResourceId), a frequency starting position (startingPRB), whether frequency hopping is adopted, and a PUCCH format. The specific configuration is shown in FIG. 1 .

图2为PUCCH格式配置中开始符号位置的配置信息示意图。图中包括在不同的PUCCH格式(PUCCH-format0~4)配置中的开始符号指示(startingSymbolIndex)。由于所示配置信息中只支持一个起始发送符号。如果存在其他系统的干扰,配置的起始发送符号会不能发起PUCCH传输,造成PUCCH承载信息无法反馈的情况。FIG. 2 is a schematic diagram of configuration information of start symbol positions in PUCCH format configuration. The figure includes starting symbol indications (startingSymbolIndex) in different PUCCH format (PUCCH-format0-4) configurations. Since only one initial transmission symbol is supported in the configuration information shown. If there is interference from other systems, the configured initial transmission symbol cannot initiate PUCCH transmission, resulting in the situation that the PUCCH bearer information cannot be fed back.

本发明中,在gNB为UE的PUCCH资源配置中,在各个PUCCH格式(PUCCH-format)中加入多个开始符号位置的指示。增加候选的开始符号个数,使得PUCCH资源配置支持多个PUCCH候选发送时间点。UE根据PUCCH资源及多个候选发送时间点,选择一个发送。In the present invention, in the PUCCH resource configuration in which the gNB is the UE, multiple indications of starting symbol positions are added to each PUCCH format (PUCCH-format). Increase the number of candidate start symbols so that the PUCCH resource configuration supports multiple PUCCH candidate transmission time points. The UE selects one for transmission according to the PUCCH resource and multiple candidate transmission time points.

所述开始符号位置表示为以下至少一种方式:The start symbol position is expressed in at least one of the following ways:

方式1:开始符号起始位置、开始符号数量值;Mode 1: start symbol start position, start symbol quantity value;

方式2:开始符号起始位置、开始符号结束位置;Mode 2: start symbol start position, start symbol end position;

方式3:离散的开始符号位置。Mode 3: Discrete start symbol positions.

方式4:在方式1~3基础上,进一步增加时隙指示。Mode 4: On the basis of modes 1 to 3, the time slot indication is further added.

图3为包含开始符号起始位置、开始符号数量值的配置信息示意图。具体地,方式1:用开始符号起始位置、开始符号数量值指示起始符号后连续多个可用作开始符号的符号数。其中加粗字体标出的开始符号数量值(StartSymbolduration)即标识在开始符号起始位置(startingSymbolIndex)后连续多个可用作开始符号的数量。如StartSymbolduration=3表示由startingSymbolIndex开始,后续3个符号也可以用作PUCCH的开始符号。FIG. 3 is a schematic diagram of configuration information including the starting position of the start symbol and the number value of the start symbol. Specifically, Mode 1: Use the start position of the start symbol and the value of the number of start symbols to indicate the number of consecutive symbols that can be used as the start symbol after the start symbol. The starting symbol quantity value (StartSymbolduration) marked in bold font is the quantity that can be used as the starting symbol in a row after the starting position (startingSymbolIndex) of the starting symbol. For example, StartSymbolduration=3 means starting from startingSymbolIndex, and the following three symbols can also be used as starting symbols of PUCCH.

图4为包含开始符号起始位置、开始符号结束位置的配置信息示意图。具体地,方式2:用开始符号起始位置、指示PUCCH开始符号最大范围。其中加粗字体标出的开始符号结束位置(endingSymbolIndex)为PUCCH最晚的结束符号。即在开始符号起始位置与开始符号结束位置之间的符号均可以用作PUCCH发送。如endingSymbolIndex为10,那么代表由startingSymbolIndex开始,一直到第10符号均可以进行该PUCCH发送。FIG. 4 is a schematic diagram of configuration information including the start position of the start symbol and the end position of the start symbol. Specifically, mode 2: use the start position of the start symbol to indicate the maximum range of the PUCCH start symbol. The starting symbol ending position (endingSymbolIndex) marked in bold font is the latest ending symbol of PUCCH. That is, the symbols between the start position of the start symbol and the end position of the start symbol can be used for PUCCH transmission. If the endingSymbolIndex is 10, it means that the PUCCH can be sent from the startingSymbolIndex to the 10th symbol.

图5为包含离散的开始符号位置的配置信息示意图。具体地,方式3:用离散的开始符号位置。指示多个PUCCH开始符号,用比特集的方式为各个符号进行标识。例如,其中加粗字体标出的候选开始符号置索引(candidateStartSymbolIndex)即为多个可能的开始符号的集合。例如,用14个比特分别指示14个符号是否可用作开始符号。FIG. 5 is a schematic diagram of configuration information including discrete start symbol positions. Specifically, Mode 3: Use discrete start symbol positions. Indicates multiple PUCCH start symbols, and identifies each symbol in the form of a bit set. For example, the candidate start symbol index (candidateStartSymbolIndex) marked in bold font is a set of multiple possible start symbols. For example, 14 bits are used to respectively indicate whether 14 symbols can be used as start symbols.

图6为包含时隙指示的配置信息示意图。优选地,所述配置信息中,还包含时隙指示。进一步地,所述时隙指示表示为:时隙数量值。具体地,方式4:进行多个可能开始符号位置的同指示时,进行多个可能开始时隙的指示。其中,多个可能开始符号的指示方式可以为以上3种方式的一种,多个开始时隙的指示为单独指示。例如,以方式1进行开始符号位置指示,同时加入时隙指示。图6中时隙数量值(slotDuration)表示在PUCCH可以开始发送的时隙后slotDuration个时隙内的多个可能开始符号都可以用于开始PUCCH发送。FIG. 6 is a schematic diagram of configuration information including time slot indication. Preferably, the configuration information further includes a time slot indication. Further, the time slot indication is expressed as: the number of time slots. Specifically, mode 4: when multiple possible start symbol positions are indicated at the same time, multiple possible start time slots are indicated. Wherein, the indication manner of the multiple possible start symbols may be one of the above three manners, and the indication of the multiple start time slots is a separate indication. For example, start symbol position indication is performed in mode 1, and time slot indication is added at the same time. The value of the number of slots (slotDuration) in FIG. 6 indicates that a plurality of possible start symbols in the slotDuration time slots after the time slot in which the PUCCH can start to transmit can be used to start the PUCCH transmission.

图7为本发明方法用于终端设备的动态的PUCCH反馈实施例流程图。FIG. 7 is a flowchart of an embodiment of the method of the present invention used for dynamic PUCCH feedback of a terminal device.

本申请实施例提出一种上行控制信息发送方法,用于终端设备,包含以下步骤:An embodiment of the present application proposes a method for sending uplink control information, which is used for a terminal device, and includes the following steps:

步骤11、终端设备接收配置信息,所述配置信息包含PUCCH开始符号位置,所述开始符号位置多于1个;Step 11. The terminal device receives configuration information, where the configuration information includes a PUCCH start symbol position, and the start symbol position is more than one;

例如,UE接收由gNB发送的含有PUCCH-Resource的配置信息,用于UE发送PUCCH。For example, the UE receives the configuration information including the PUCCH-Resource sent by the gNB for the UE to send the PUCCH.

举例来说,gNB通过高层的RRC信令发送多个PUCCH-Resource集合,每个PUCCH-Resource集合中有多个PUCCH-Resource配置(例如图1)。通过该信令,UE可获得多个PUCCH-Resource配置,每个配置通过本发明方式,具有多个PUCCH可能的起始发送符号(例如图3~6)。在每1个时隙内包含14个符号时,该时隙内最多可以定义14个开始符号位置。For example, the gNB sends multiple PUCCH-Resource sets through high-layer RRC signaling, and each PUCCH-Resource set has multiple PUCCH-Resource configurations (eg, FIG. 1 ). Through this signaling, the UE can obtain multiple PUCCH-Resource configurations, and each configuration has multiple possible initial transmission symbols of the PUCCH through the method of the present invention (eg, FIGS. 3-6 ). When each time slot contains 14 symbols, a maximum of 14 starting symbol positions can be defined in the time slot.

步骤12、接收PUCCH资源指示信息,所述资源指示信息,包含PUCCH资源配置参数,所述PUCCH资源指示信息包含于下行控制信令中;Step 12: Receive PUCCH resource indication information, where the resource indication information includes PUCCH resource configuration parameters, and the PUCCH resource indication information is included in downlink control signaling;

例如,UE接收下行控制信道(PDCCH),通过PDCCH中的PDSCH-to-HARQ-timing-indicator和PUCCH resource indicator来决定PUCCH发送的时隙(slot)信息和具体PUCCH发送配置。For example, the UE receives the downlink control channel (PDCCH), and determines the time slot information for PUCCH transmission and the specific PUCCH transmission configuration through PDSCH-to-HARQ-timing-indicator and PUCCH resource indicator in the PDCCH.

其中PDSCH-to-HARQ-timing-indicator用于指示UE在收到PDCCH后若干时隙进行PUCCH发送;PUCCH resource indicator则具体指示在如图1的多个PUCCH-Resource配置中具体采用哪一个进行PUCCH发送。确定一种PUCCH配置后,根据步骤11,UE就获得PUCCH发送格式及多个可用于PUCCH发送的候选位置。The PDSCH-to-HARQ-timing-indicator is used to instruct the UE to perform PUCCH transmission in several time slots after receiving the PDCCH; the PUCCH resource indicator specifically indicates which one to use for the PUCCH in the multiple PUCCH-Resource configurations as shown in Figure 1 send. After a PUCCH configuration is determined, according to step 11, the UE obtains the PUCCH transmission format and multiple candidate positions that can be used for PUCCH transmission.

步骤13、在所述开始符号位置对信道进行持续监听,选择空闲的开始符号位置发送PUCCH。Step 13: Continuously monitor the channel at the start symbol position, and select an idle start symbol position to send the PUCCH.

例如,UE根据多个可发送位置,选择一个位置进行PUCCH实际发送。UE根据步骤12确定的多个PUCCH候选位置,准备相应的PUCCH发送数据。在候选位置上,UE依时间顺序依次进行信道监测。如果监测结果为信道未被占用,可以进行PUCCH发送,那么UE进行PUCCH发送。如果信道监测结果为信道被占用,则不进行PUCCH发送。For example, the UE selects a location to actually transmit the PUCCH according to multiple transmittable locations. The UE prepares corresponding PUCCH transmission data according to the multiple PUCCH candidate positions determined in step 12 . At the candidate positions, the UE performs channel monitoring in chronological order. If the monitoring result is that the channel is not occupied and the PUCCH can be sent, the UE sends the PUCCH. If the channel monitoring result is that the channel is occupied, no PUCCH transmission is performed.

举例说明,当UE根据PUCCH-Resource指示,获得可发送的PUCCH的候选位置为第0至第5符号。那么,UE根据指示的格式,准备好第0至第5符号发送PUCCH数据。同时,UE进行信道的持续监听(LBT),从0符号开始,一旦信道空闲,可以进行数据发送,UE进行相应符号的PUCCH发送。For example, when the UE obtains the candidate positions of the transmittable PUCCH according to the PUCCH-Resource indication, the 0th to 5th symbols are. Then, the UE prepares the 0th to 5th symbols to send PUCCH data according to the indicated format. At the same time, the UE performs continuous monitoring (LBT) of the channel, starting from symbol 0. Once the channel is idle, data transmission can be performed, and the UE performs PUCCH transmission of the corresponding symbol.

与图7所示实施例相对应地,网络设备(gNB)侧的工作过程实施例,包含以下步骤:Corresponding to the embodiment shown in FIG. 7 , the working process embodiment on the network device (gNB) side includes the following steps:

步骤21、网络设备发出配置信息,所述配置信息包含PUCCH开始符号位置,所述开始符号位置多于1个;Step 21, the network device sends configuration information, the configuration information includes the PUCCH start symbol position, and the start symbol position is more than one;

例如gNB通过高层信令(例如RRC信令)为UE进行PUCCH相关配置,包括各种PUCCH-Resource配置;For example, the gNB performs PUCCH related configuration for the UE through high-layer signaling (such as RRC signaling), including various PUCCH-Resource configurations;

步骤22、网络设备发送下行控制信令,其中包含PUCCH资源指示信息;例如,gNB发送包含PUCCH反馈时隙与配置指示字段的下行控制信息;Step 22, the network device sends downlink control signaling, which includes PUCCH resource indication information; for example, gNB sends downlink control information including PUCCH feedback time slot and configuration indication field;

图9为本发明方法用于终端设备的半静态的PUCCH反馈实施例流程图。FIG. 9 is a flowchart of an embodiment of the method of the present invention used for semi-static PUCCH feedback of a terminal device.

本申请实施例提出一种上行控制信息发送方法,用于终端设备,包含以下步骤:An embodiment of the present application proposes a method for sending uplink control information, which is used for a terminal device, and includes the following steps:

步骤31、终端设备接收配置信息,所述配置信息包含PUCCH开始符号位置,所述开始符号位置多于1个;Step 31, the terminal device receives configuration information, where the configuration information includes the PUCCH start symbol position, and the start symbol position is more than one;

步骤31中,UE接收由gNB发送的含有PUCCH-Resource的PUCCH发送配置。In step 31, the UE receives the PUCCH transmission configuration including the PUCCH-Resource sent by the gNB.

举例来说,gNB通过高层的RRC信令发送多个PUCCH-Resource配置给UE。通过该信令,UE可获得多个PUCCH-Resource配置,每个配置通过本发明方式,具有多个PUCCH可能的起始发送符号。For example, the gNB sends multiple PUCCH-Resource configurations to the UE through high-layer RRC signaling. Through this signaling, the UE can obtain multiple PUCCH-Resource configurations, and each configuration has multiple possible initial transmission symbols of the PUCCH through the method of the present invention.

步骤32、接收PUCCH资源指示信息,所述资源指示信息,包含PUCCH资源配置参数,所述PUCCH资源指示信息包含于高层信令中。Step 32: Receive PUCCH resource indication information, where the resource indication information includes PUCCH resource configuration parameters, and the PUCCH resource indication information is included in higher layer signaling.

例如,UE接收半静态的PUCCH反馈信令。该信令类型如CSI-ReportConfig。该信令中包括PUCCH发送的相关信息PUCCH-CSI-Resource及CSI-ReportPeriodicityAndOffset。For example, the UE receives semi-static PUCCH feedback signaling. The signaling type is such as CSI-ReportConfig. The signaling includes related information PUCCH-CSI-Resource and CSI-ReportPeriodicityAndOffset sent by PUCCH.

其中CSI-ReportPeriodicityAndOffset用于指示PUCCH反馈时隙位置;PUCCH-CSI-Resource则具体指示多个PUCCH-Resource配置中具体采用哪一个进行PUCCH发送。确定一种PUCCH配置后,根据步骤31,UE就获得PUCCH发送格式及多个可用于PUCCH发送的候选位置。The CSI-ReportPeriodicityAndOffset is used to indicate the position of the PUCCH feedback time slot; the PUCCH-CSI-Resource specifically indicates which one of the multiple PUCCH-Resource configurations is specifically used for PUCCH transmission. After a PUCCH configuration is determined, according to step 31, the UE obtains the PUCCH transmission format and multiple candidate positions that can be used for PUCCH transmission.

需要说明的是,如果此时遇到方式4配置的多个可能时隙指示,则不进行方式4的多时隙PUCCH发送,只根据CSI-ReportPeriodicityAndOffset指示的周期进行PUCCH发送。It should be noted that, if multiple possible time slot indications configured in mode 4 are encountered at this time, the multi-slot PUCCH transmission in mode 4 is not performed, and PUCCH transmission is only performed according to the period indicated by CSI-ReportPeriodicityAndOffset.

步骤33、在所述开始符号位置对信道进行持续监听,选择空闲的开始符号位置发送PUCCH。Step 33: Continuously monitor the channel at the start symbol position, and select an idle start symbol position to send the PUCCH.

步骤33中,UE根据多个可发送位置,选择一个位置进行PUCCH实际发送。UE根据步骤32确定的多个PUCCH候选位置,准备相应的PUCCH发送数据。在候选位置上,UE依时间顺序依次进行信道的监测。如果监测结果为信道未被占用,那么UE进行PUCCH发送。如果信道监测结果为信道被占用,则不进行PUCCH发送。In step 33, the UE selects a location to actually transmit the PUCCH according to multiple transmittable locations. The UE prepares corresponding PUCCH transmission data according to the multiple PUCCH candidate positions determined in step 32 . At the candidate positions, the UE performs channel monitoring in chronological order. If the monitoring result is that the channel is not occupied, the UE performs PUCCH transmission. If the channel monitoring result is that the channel is occupied, no PUCCH transmission is performed.
