- Satellite communication is not restricted by the user area.
- general terrestrial communication cannot cover areas where communication equipment cannot be installed, such as oceans, mountains, and deserts, or areas that cannot be covered by communication due to sparse population.
- satellite communication because A satellite can cover a large area of the ground, and the satellite can orbit the earth, so in theory, every corner of the earth can be covered by satellite communications.
- satellite communication has greater social value.
- Satellite communication can be covered at a lower cost in remote mountainous areas, poor and backward countries or regions, so that people in these areas can enjoy advanced voice communication and mobile Internet technology, which is conducive to narrowing the digital gap between these areas and developed areas. To promote the development of these areas. Third, the satellite communication distance is long, and with the increase of the communication distance, the communication cost has not increased significantly; finally, the stability of satellite communication is high, and it is not restricted by natural disasters.
- communication satellites can be divided into: Low-Earth Orbit (LEO) satellites, Medium-Earth Orbit (MEO) satellites, Geostationary Earth Orbit (GEO) Satellites, High Elliptical Orbit (HEO) satellites, etc.
- LEO Low-Earth Orbit
- MEO Medium-Earth Orbit
- GEO Geostationary Earth Orbit
- HEO High Elliptical Orbit
- 3GPP mainly studies LEO satellites and GEO satellites.
- the LEO satellite's orbital altitude ranges from 500 kilometers (km) to 1500km, and the corresponding orbital period is about 1.5 hours to 2 hours.
- the signal propagation delay of single-hop communication between users is generally less than 20 milliseconds (ms), and the maximum satellite visible time is 20 minutes.
- the NTN technology based on LEO satellites has the characteristics of short signal propagation distance, low link loss, and low requirements for the transmission power of the user terminal.
- the orbital height of the GEO satellite is 35786km, and the rotation period around the earth is 24 hours.
- the signal propagation delay of single-hop communication between users is generally 250ms.
- the satellite uses multiple beams to cover the ground, that is, a satellite can form dozens or even hundreds of satellite beams to cover the ground.
- a satellite beam can cover a ground area with a diameter of tens to hundreds of kilometers.
- the functions or protocols of NR suitable for terrestrial communications need to be appropriately adjusted to adapt to the NTN technology.
- the HARQ mechanism in the NR protocol suitable for terrestrial communications needs to be adjusted to adapt to the integration of satellite communications and terrestrial communications.
- the NR protocol defines two levels of retransmission mechanisms, namely the HARQ mechanism at the Medium Access Control (MAC) layer and the Automatic Repeat Request (Automatic Repeat Request) at the Radio Link Control (RLC) layer.
- ARQ Automatic Repeat Request
- the retransmission of lost or erroneous data is mainly handled by the HARQ mechanism of the MAC layer and supplemented by the retransmission function of the RLC layer.
- the HARQ mechanism of the MAC layer can provide fast data retransmission, and the ARQ mechanism of the RLC layer can provide reliable data transmission.
- the Hybrid Automatic Repeat reQuest (HARQ) mechanism uses the Stop-and-Wait Protocol (also called the SQW protocol) to send data.
- Stop-and-wait protocol also called the SQW protocol
- the sender stops and waits for confirmation information.
- This process can also be referred to as HARQ feedback.
- NR uses multiple parallel HARQ processes to send data blocks. When one HARQ process is waiting for confirmation information, the sender can use another HARQ process to continue sending data blocks.
- the multiple HARQ processes together form a HARQ entity, which combines a stop-and-wait protocol to allow data blocks to be continuously sent.
- the multiple HARQ processes include an uplink HARQ process and a downlink HARQ process.
- the uplink HARQ process and the downlink HARQ process are independent of each other and do not affect each other.
- the number of the uplink HARQ process and the downlink HARQ process may be the same.
- the uplink HARQ process is aimed at the transmission of uplink data.
- the downlink HARQ process is aimed at downlink data transmission.
- the confirmation message includes ACK and NACK. If the acknowledgement is received successfully, the acknowledgement message is ACK, and if the acknowledgement fails, the acknowledgement message is NACK.
- each serving cell corresponding to the terminal has its own HARQ entity.
- Each HARQ entity is responsible for maintaining a set of parallel downlink HARQ processes and a set of parallel uplink HARQ processes.
- each uplink carrier and downlink carrier supports a maximum of 16 HARQ processes.
- the base station can indicate the maximum number of HARQ processes to the terminal through the semi-static configuration of radio resource control (Radio Resource Control, RRC) signaling according to the network deployment situation. If the network does not provide corresponding configuration parameters, the default maximum number of HARQ processes supported by each downlink carrier is 8, and the maximum number of HARQ processes supported by each uplink carrier is always 16.
- RRC Radio Resource Control
- Each HARQ process corresponds to a HARQ process number (Identity or Identification, ID).
- ID HARQ process number
- the Broadcast Control Channel BCCH
- Msg3 is transmitted in the random process using HARQ ID 0.
- each downlink HARQ process can only process 1 TB at a time; for terminals that support downlink space division multiplexing, each downlink HARQ process can process 1 or 2 TB at a time.
- Each uplink HARQ process of the terminal processes 1 TB at a time.
- the HARQ mechanism can be divided into a synchronous HARQ mechanism and an asynchronous HARQ mechanism in the time domain, and a non-adaptive HARQ mechanism and an adaptive HARQ mechanism in the frequency domain.
- the uplink and downlink transmissions in the NR protocol use the asynchronous adaptive HARQ mechanism.
- the asynchronous HARQ mechanism refers to the retransmission of a TB at any time.
- the adaptive HARQ mechanism refers to the ability to change the frequency domain resources and modulation and coding strategy (Modulation and Coding Scheme, MCS) used for retransmission of the TB.
- MCS Modulation and Coding Scheme
- NR can support semi-static resource configuration.
- the semi-static resource configuration refers to that the network side device allocates scheduling resources to the terminal through the DCI carried by the PDCCH, and the terminal sends or receives service data according to the scheduled resources in each fixed period.
- the semi-static resource configuration can include the configuration grant (CG) for the uplink transmission link (Upper Link, UL) and the semi-persistent scheduling (Semi-Persistent Scheduling, SPS) for the downlink transmission link (Down Link, DL). ).
- CG configuration grant
- SPS semi-persistent scheduling
- Type 1 CG means that when the UE receives the RRC configuration, the user equipment (User Equipment, UE) can use or configure , Namely activation, Type 2 CG is when the UE receives the RRC configuration and saves the RRC configuration, when the subsequent DCI indicates that the CG is activated or deactivated, the CG resource can be activated (used) or deactivated (not used).
- the network side device When configuring CG or SPS, the network side device also indicates the number of HARQ processes that can be used by the corresponding CG resource or SPS resource.
- the UE can calculate the HARQ process ID corresponding to the CG resource according to the HARQ process data. For example, define the variables of the HARQ process with a maximum number of 16:
- composite SPS or composite CG is supported in R16, it can be configured in RRC accordingly, and the HARQ process offset value (offset) can also be indicated at the same time.
- the UE can calculate the HARQ process ID corresponding to the CG resource according to the HARQ process data and the HARQ process offset.
- the network-side equipment allocates uplink transmission resources based on the UE (per-UE) instead of the bearer (per-bearer), based on which radio bearers the data of the UE refers to can be put into the allocated uplink transmission resources.
- the transmission is determined by the UE.
- the UE Based on the uplink transmission resources configured by the network-side device, the UE needs to determine the amount of transmission data for each logical channel in the initial transmission MAC protocol data unit (PDU). In some cases, the UE also needs to be a MAC control unit. (Control Element, CE) allocates resources. In order to realize the multiplexing of uplink logical channels, each uplink logical channel needs to be assigned a priority. For a given size of MAC PDU, when there are multiple uplink logical channels that have data transmission requirements at the same time, the resources of the MAC PDU are allocated in order of the priority of the logical channel corresponding to each uplink logical channel. . That is to say, in the existing logical channel priority (Logical Channel Prioritization, LCP) rules, only the priority of the LCH is considered, and logical channel mapping is performed to perform data transmission.
- LCP Logical Channel Prioritization
- the UE follows the following priority order (arranged in order of priority from high to low) when performing logical channel priority processing:
- C-RNTI Cell radio network temporary identification
- UL-CCCH uplink common control channel
- a single power headroom report (Single Entry PHR) MAC CE or multiple power headroom reports (Multiple Entry PHR) MAC CE;
- BSR MAC CE used to fill the buffer status report (padding BSR).
- the wireless signal transmission between the terminal and the satellite has a long time delay.
- the introduction of the disabling HARQ function is being discussed to reduce the data transmission delay, and it can be based on the HARQ process.
- Perform the configuration of enabling or disabling the HARQ function that is, for multiple HARQ processes of a terminal, the HARQ function of some of the HARQ processes can be configured in the enabled state, and the HARQ function of the other part of the HARQ processes can be configured in the disabled state.
- the network can not wait to receive the uplink transmission of the UE (for uplink HARQ, it is the uplink data transmission, and for the downlink HARQ, it is the UE's ACK for the HARQ downlink data transmission. /NACK feedback) and continue to schedule the HARQ process for data transmission, thereby reducing the MAC transmission delay; on the other hand, if the network no longer schedules the HARQ process for retransmission, the reliability of MAC transmission will be affected.
- the network side device can allocate logical channels with different QoS requirements to different HARQ processes for transmission according to the QoS requirements of different logical channels when scheduling resources.
- the current UL resource allocation is only allocated by the network-side device based on the UE, and does not indicate which logical channels can use the allocated resources for transmission.
- the network side device wants to transfer LCH1
- the information of is placed on the HARQ process that is in the disabled state for resource transmission, and the information of LCH2 is placed on the HARQ process that is in the enabled state for resource transmission. Therefore, for the HARQ process with the HARQ function turned off and the HARQ process with the HARQ function turned on, how to complete the uplink logical channel multiplexing requires a set of rules from the standard level.
- the HARQ process may be set with an enabled state, or the HARQ process may not be set with an enabled state.
- the HARQ process includes the HARQ process in the disabled state and the HARQ process in the enabled state.
- Turning on the HARQ function means that the HARQ process is in the enabled state
- turning off the HARQ function means that the HARQ process is in the disabled state.
- the HARQ process without the enabled state can perform ACK/NACK feedback the same as the HARQ process with the HARQ function enabled.
- the HARQ process without the enabled state can also be the HARQ process without ACK/NACK feedback.
- This application is implemented The example does not limit this.
- the HARQ process that is not provided with the HARQ function can also be understood as the HARQ process that does not limit the logical channel mapping situation, that is, according to the first information, any logical channel can correspond to it.
- the uplink transmission of is sent on the HARQ process.
- the HARQ process in the disabled state and the HARQ process in the enabled state can be referred to as two types of HARQ processes, and can also be referred to as two types of HARQ processes.

非地面通信网络(Non Terrestrial Network,NTN)技术是一种采用卫星通信的方式向地面用户提供通信服务的技术,其相比于地面通信具有很多优点,例如,NTN技术可以不受用户地域的限制,为地面通信难以通信覆盖的区域提供服务,再例如,对于山地、荒漠及海上等地区,NTN技术相较于地面通信具有较低的通信成本。

为使本申请的目的、技术方案和优点更加清楚,下面将结合附图对本申请实施方式作进一步地详细描述。
目前3GPP正在研究NTN技术,NTN技术一般采用卫星通信的方式向地面用户提供通信服务。相比于地面通信(例如地面蜂窝网),卫星通信具有很多独特的优点。首先,卫星通信不受用户地域的限制,例如一般的陆地通信不能覆盖海洋、高山以及沙漠等无法搭设通信设备的区域,或者由于人口稀少而不做通信覆盖的区域,对于卫星通信来说,由于一颗卫星即可以覆盖较大的地面区域,加之卫星可以围绕地球做轨道运动,因此理论上地球上每一个角落都可以被卫星通信覆盖。其次,卫星通信具有较大的社会价值。卫星通信在边远山区、贫穷落后的国家或地区都可以以较低的成本覆盖,从而使这些地区的人们享受到先进的语音通信和移动互联网技术,有利于缩小这些区域与发达地区的数字鸿沟,以促进这些区域的发展。再次,卫星通信距离远,并且随着通信距离的增大,通讯成本并没有明显增加;最后,卫星通信的稳定性高,不受自然灾害的限制。
按照通信卫星的轨道高度,可以将通信卫星分为:低地球轨道(Low-Earth Orbit,LEO)卫星、中地球轨道(Medium-Earth Orbit,MEO)卫星、地球同步轨道(Geostationary Earth Orbit,GEO)卫星、高椭圆轨道(High Elliptical Orbit,HEO)卫星等等。目前阶段3GPP主要研究的是LEO卫星和GEO卫星。其中,LEO卫星的轨道高度范围为500千米(km)至1500km,相应的轨道周期约为1.5小时至2小时。用户间单跳通信的信号传播延迟一般小于20毫秒(ms),最大卫星可视时间为20分钟。基于LEO卫星的NTN技术具有信号传播距离短、链路损耗少以及对用户终端的发射功率要求不高的特点。GEO卫星的轨道高度为35786km,围绕地球旋转周期为24小时,用户间单跳通信的信号传播延迟一般为250ms。为了保证卫星在地球上的覆盖面积以及提升整个卫星通信系统的系统容量,卫星采用多波束覆盖地面,也即是,一颗卫星可以形成几十甚至数百个卫星波束来覆盖地面,其中,每个卫星波束可以覆盖直径几十至上百公里的地面区域。
在将卫星通信与地面通信进行融合的过程中,适用于地面通信的NR的功能或者协议需要进行适当的调整以适应NTN技术。例如,适用于地面通信的NR协议中的HARQ机制便需要为适应卫星通信与地面通信的融合进行调整。
为了有助于理解本申请实施例的相关描述,在此首先对NR协议中的HARQ机制进行简要介绍:
在NR协议定义了两级重传机制,分别是媒质接入控制(Medium Access Control,MAC)层的HARQ机制和无线链路控制(Radio Link Control,RLC)层的自动重复请求(Automatic Repeat Request,ARQ)机制。其中,丢失 或出错的数据的重传主要是由MAC层的HARQ机制处理的,再由RLC层的重传功能进行补充。MAC层的HARQ机制能够提供快速的数据重传,RLC层的ARQ机制能够提供可靠的数据传输。
混合自动重传请求(Hybrid Automatic Repeat reQuest,HARQ)机制使用停等协议(Stop-and-Wait Protocol,也称SQW协议)来发送数据。在停等协议中,发送端在发送一个传输块(Transmission Block,TB)之后,就停下来等待确认信息,该过程也可称为HARQ反馈。如此使得发送端在每发送一个TB之后,均会停下来等待确认,导致用户吞吐量很低。因此,为了提高用户吞吐量,NR采用多个并行的HARQ进程进行数据块的发送,当一个HARQ进程在等待确认信息时,发送端可以使用另一个HARQ进程来继续发送数据块。这些HARQ进程共同组成了一个HARQ实体,该HARQ实体结合了停等协议,允许数据块进行连续发送。其中,该多个HARQ进程包括上行HARQ进程和下行HARQ进程,上行HARQ进程和下行HARQ进程相互独立互不影响,上行HARQ进程和下行HARQ进程的数量可以相同,该上行HARQ进程针对上行数据的传输,下行HARQ进程针对下行数据传输。确认消息包括ACK以及NACK。若确认接收成功则该确认消息为ACK,如果确认接受失败则该确认消息为NACK。
适用于地面通信的NR协议中规定,终端对应的每个服务小区都有各自的HARQ实体。每个HARQ实体负责维护一组并行的下行HARQ进程和一组并行的上行HARQ进程。目前每个上行载波和下行载波均支持最多16个HARQ进程。基站可以根据网络部署情况通过无线资源控制(Radio Resource Control,RRC)信令的半静态配置向终端指示最大的HARQ进程数量。如果网络没有提供相应的配置参数,则每个下行载波支持的缺省的最大HARQ进程数量为8个,而每个上行载波支持的最大HARQ进程数量始终为16个。每个HARQ进程对应一个HARQ进程号(Identity或Identification,ID)。对于下行传输,广播控制信道(Broadcast Control Channel,BCCH)使用一个专用的广播HARQ进程。对于上行传输,随机过程中的传输第三消息Msg3使用HARQ ID 0。
对于不支持下行空分复用的终端,每个下行HARQ进程只能一次处理1个TB;对于支持下行空分复用的终端,每个下行HARQ进程可以一次处理1个或者2个TB。终端的每个上行HARQ进程一次处理1个TB。HARQ机制在时域上可以分为同步HARQ机制和异步HARQ机制,在频域上分为非自适应HARQ机制和自适应HARQ机制。NR协议中的上下行传输均使用异步自适应HARQ机制,其中,异步HARQ机制指的是TB的重传可以发生在任意时刻,对于同一个TB,其重传与上一次传输的时间间隔是不固定的;自适应HARQ机制指的是可以改变重传TB所使用的频域资源和调制与编码策略(Modulation and Coding Scheme,MCS)。
其次,对NR协议中的半静态的资源配置进行简要介绍:
为了支持周期性且业务量基本固定的业务,同时减少频繁的物理下行控制信道(Physical Downlink Control Channel,PDCCH)调度开销,NR可以支持半静态的资源配置。其中,半静态的资源配置指的是,网络侧设备通过PDCCH承载的DCI为终端分配调度资源,终端每个固定的周期根据该调度资源发送或接收业务数据。半静态的资源配置可以包括针对上行传输链路(Upper Link,UL)的配置授权(Configured Grant,CG)以及针对下行传输链路(Down Link,DL)的半持续调度(Semi-Persistent Scheduling,SPS)。对CG来说,可以包括两种类型,分别为类型1(type1)和类型2(type2),其中,type1CG是当UE接收到RRC配置后,用户设备(User Equipment,UE)即可使用或配置,即激活,Type2 CG是当UE接收到RRC配置后保存该RRC配置,当后续收到DCI指示该CG激活或去激活时,方可激活(使用)或去激活(不使用)该CG资源。
在配置CG或者SPS时,网络侧设备同时指示对应CG资源或者SPS资源可以使用的HARQ进程数目。UE可以根据HARQ进程数据计算出对应该CG资源的HARQ进程ID。例如,定义最大数目为16的HARQ进程的变量:
nrofHARQ-Processes INTEGER(1..16),
由于在R16中支持了复合SPS或者复合CG,因此可以相应地在RRC中配置,也可同时指示HARQ进程偏移值(offset)。UE可以根据HARQ进程数据和HARQ进程offset计算出对应该CG资源的HARQ进程ID。
最后,对NR协议中的逻辑信道(Logic Channel,LCH)优先级进行简要介绍:
在NR中,网络侧设备基于UE(即per-UE)而不是基于承载(即per-bearer)分配上行传输资源,基于UE指的是哪些无线承载的数据能够放入分配的上行传输资源中进行传输是由UE决定的。
基于网络侧设备配置的上行传输资源,UE需要决定在初传MAC协议数据单元(Protocol Data Unit,PDU)中的每个逻辑信道的传输数据量,在某些情况下UE还要为MAC控制单元(Control Element,CE)分配资源。为了实现上行逻辑信道的复用,需要为每个上行逻辑信道分配一个优先级。对于一个给定大小的MAC PDU,在有多个上行逻辑信道同时有数据传输需求的情况下,按照有各个上行逻辑信道对应的逻辑信道优先级从大到小的顺序依次分配该MAC PDU的资源。也就是说,在现有的逻辑信道优先级(Logical Channel prioritization,LCP)规则中,仅考虑LCH的优先级,进行逻辑信道映射,从而进行数据传输。
具体的,对于不同的信号和/或逻辑信道,UE进行逻辑信道优先级处理时遵循以下优先级顺序(按照优先级从高到低的顺序排列):
1)小区无线网络临时标识(C-RNTI)MAC CE或来自上行公共控制信道(UL-CCCH)的数据;
2)配置授权确认(Configured Grant Confirmation)MAC CE;
3)用于除填充缓冲区状态报告(padding BSR)之外的BSR MAC CE;
4)单次功率余量报告(Single Entry PHR)MAC CE或者多次功率余量报告(Multiple Entry PHR)MAC CE;
5)来自除UL-CCCH之外的任意逻辑信道的数据;
6)用于推荐的比特率查询(Recommended bit rate query)的MAC CE;
7)用于填充缓冲区状态报告(padding BSR)的BSR MAC CE。
在目前的NTN系统中,终端与卫星之间的无线信号传输存在时延较大,在3GPP对NTN标准化过程中正在讨论引入去使能HARQ功能以降低数据传输时延,并且同意可以基于HARQ进程进行使能或去使能HARQ功能的配置,即对于一个终端的多个HARQ进程,可以配置其中一部分HARQ进程的HARQ功能为使能状态,另一部分HARQ进程的HARQ功能为去使能状态。
将某个HARQ进程的HARQ功能配置为去使能状态,一方面,网络可以不等待接收UE的上行传输(对于上行HARQ为上行数据传输,对于下行HARQ为UE针对该HARQ的下行数据传输的ACK/NACK反馈)而继续调度该HARQ进程进行数据传输,从而降低MAC传输时延;而另一方面,如果网络不再调度该HARQ进程进行重传,MAC传输可靠性会收到影响。
由于不同的业务有不同的QoS要求,比如有些业务对时延敏感,有些业务对丢包率有严格的要求。对于时延敏感的业务,可以使用HARQ功能配置为去使能状态的HARQ进程进行传输,从而降低传输时延;对于对丢包率有严格要求的业务,而可以使用HARQ功能配置为使能状态的HARQ进程进行传输,从而提高传输可靠性。
对于下行传输,网络侧设备在调度资源时可以根据不同逻辑信道的QoS要求,将具有不同QoS要求的逻辑信道分配到不同的HARQ进程上去传输。对于上行传输,当前的UL资源分配仅是网络侧设备基于UE分配的,而不指示哪些逻辑信道可以使用该分配的资源进行传输。而按照现有的LCP,UE对收到的UL进行LCP时,仅考虑优先级,而不考虑资源是否对应HARQ功能使能/去使能的特性,这就可能造成具有不同QoS要求的逻辑信道未能分配到不同的HARQ进程上,导致业务传输QoS不能保证,造成与网络资源分配初衷违背的情况,例如,根据待传输的LCH信息(例如BSR或者buffer status report),网络侧设备想将LCH1的信息放在处于去使能的HARQ进程上进行资源传输,将LCH2的信息放在处于使能状态的HARQ进程上进行资源传输。因此,对于关闭HARQ功能的HARQ进程和开启HARQ功能的HARQ进程,如何完成上行逻辑信道复用,需要从标准层面制定一套规则。
需要提前说明的是,在本申请实施例中,HARQ进程可以设置有使能状态,也可以未设置有使能状态的HARQ进程。当HARQ进程设置有使能状态时,基于该HARQ功能使得HARQ进程包括处于去使能状态的HARQ进程和处于使能状态的HARQ进程。开启HARQ功能指的是HARQ进程处于使能状态,关闭HARQ功能指的是HARQ进程处于去使能状态。未设置有使能状态的HARQ进程可以和开启HARQ功能的HARQ进程一样均进行ACK/NACK反馈,当然,未设置使能状态的HARQ进程也可以是HARQ进程不进行ACK/NACK反馈,本申请实施例对此不进行限定。在本申请接下来的实施例中,未设置有HARQ功能的HARQ进程也可以理解为不限制逻辑信道映射情况的HARQ进程,也即是,根据第一信息,任何一个逻辑信道均可以将其对应的上行传输在该HARQ进程上进行发送。处于去使能状态的HARQ进程和处于使能状态的HARQ进程可以称为两种属性的HARQ进程,也可以称为两种类型的HARQ进程。

图3示出了该第一种数据传输方法的流程图,该数据传输方法中,上行资源包括上行CG资源(也可称为CG资源,该CG资源可以为type1CG和/或type 2 CG)。该方法包括:
步骤301、接收上行资源的资源配置信令,该资源配置信令携带有第一信息。
该资源配置信令中携带有第一信息,该第一信息可以包括其中至少一个信息项,当第一信息包括两个以上信息项时,不同的信息项可以携带在相同或不同的资源配置信令中。示例性的,资源配置信令包括无线资源控制(Radio Resource Control,RRC)信令,RRC信令包括用于配置该上行CG资源的RRC信令。该RRC信令可以包括configuredgrantconfig IE。

根据接收到的资源配置信令配置CG资源以及与该配置的CG资源对应的HARQ相关参数,并配置或确定第一逻辑信道和/或第二逻辑信道。该第一逻辑信道包括允许在处于去使能状态的HARQ进程对应的资源上进行传输的逻辑信道,第二逻辑信道包括禁止在处于去使能状态的HARQ进程对应的资源上进行传输的逻辑信道,或者,允许在处于使能状态的HARQ进程对应的资源上进行传输的逻辑信道。
步骤302、根据该第一信息,将第一逻辑信道对应的上行传输在上行资源上进行发送。
可选的,用于配置该上行CG资源的RRC信令可以包括用于配置type1的上行CG资源的RRC信令,也可以包括用于配置type2的上行CG资源的RRC信令。
若根据RRC信令配置的CG资源为type1CG,当UE收到该资源配置信令后,即可使用该CG资源进行数据传输;若配置的CG资源为type2 CG,当UE收到该资源配置信令,且收到DCI信令指示激活后,可使用该CG资源进行数据传输。
在本申请实施例中,第一信息可以为上述步骤301中描述的至少一个信息项中第1项、第2项以及第5项至第12项中的至少一种。上行CG资源对应的HARQ进程所具有的HARQ功能可以包括三种情况:HARQ功能为使能状态,HARQ功能为去使能状态,未设定HARQ功能。因此,步骤302可以分为以下三种情况:
在第一种情况中,在UE使用该CG资源进行新传时,若UE根据该第一信息,确定该上行CG资源对应的HARQ功能为去使能状态,由于预先设置第一逻辑信道包括允许在处于去使能状态的HARQ进程对应的资源上进行传输的 逻辑信道,则UE仅将第一逻辑信息对应的上行数据和/或至少与该第一逻辑信道对应的MAC CE映射在该上行CG资源上。
在第二种情况中,在UE使用该CG资源进行新传时,若UE根据该第一信息,确定该上行CG资源对应的HARQ功能为使能状态,由于第二逻辑信道为禁止在处于去使能状态的HARQ进程对应的资源上进行传输的逻辑信道,或者,允许在处于使能状态的HARQ进程对应的资源上进行传输的逻辑信道,则UE仅将第二逻辑信息对应的上行数据和/或至少与该第二逻辑信道对应的MAC CE映射在该上行CG资源上。
在第三种情况中,在UE使用该CG资源进行新传时,若UE根据该第一信息,确定该上行CG资源对应的HARQ进程未设置HARQ功能,由于第二逻辑信道为禁止在处于去使能状态的HARQ进程对应的资源上进行传输的逻辑信道,或者,允许在处于使能状态的HARQ进程对应的资源上进行传输的逻辑信道,则UE仅将第二逻辑信息对应的上行数据和/或至少与该第二逻辑信道的MAC CE映射在该上行CG资源上;或者,UE将第一逻辑信道和第二逻辑信道对应的上行数据和/或至少与该逻辑信道对应的MAC CE映射在该上行CG资源上。
需要说明的是,若资源配置信息中未指示第二逻辑信道,UE可以根据第一逻辑信道在总的所有逻辑信道中确定出第二逻辑信道。同理,若资源配置信息中未指示第一逻辑信道,UE可以根据第二逻辑信道在总的所有逻辑信道中确定出第一逻辑信道。
图4示出了针对图3所描述的数据传输方法的一种具体实施例示意图。假设UE建立了4条上行逻辑信道,分别为LCH1,LCH2,LCH3和LCH4。在本申请实施例中,以第一信息包括逻辑信道的标识为例进行说明。
步骤a1、UE接收网络侧设备发送的资源配置信令,UE根据该资源配置信令配置了如下内容:
两套CG资源,分别对应CG index1和CG index2,且均为type1的CG资源;
其中,与CG index1的CG资源对应的2个HARQ进程,对应的HARQ ID分别为1和2,配置HARQ ID1为去使能的HARQ进程,配置HARQ ID2为使能的HARQ进程,可以在CG index1上传输的LCH为LCH1至LCH4,配置第一逻辑信道标识为LCH1和LCH2,第二逻辑信道标识为LCH3和LCH4;
与CG index2的CG资源对应的2个HARQ进程,对应的HARQ ID分别为3和4,配置HARQ ID3为去使能的HARQ进程,HARQ ID4为使能的HARQ进程,可以在CG index2上传输的LCH为LCH2和LCH4,配置第一逻辑信道标识为LCH2,第二逻辑信道标识为LCH4。
步骤a2、根据第一信息,将第一逻辑信道对应的上行传输在上行资源上进行发送。
在t1时刻为CG index1的CG资源的位置,对应的HARQ进程为HARQ ID1,此时每个LCH都有待传输数据可以传输,但是由于HARQ ID1为去使能的HARQ进程且第一逻辑信道标识为LCH1,LCH2,则UE使用该上行CG资源仅传输LCH1和LCH2对应的上行数据,也即是,UE仅将LCH1和LCH2对应的上行数据在该上行资源上进行发送。
在t2时刻为CG index1的CG资源的位置,对应的HARQ进程为HARQ ID2,此时每个LCH都有待传输数据可以传输,但是由于HARQ ID2为使能的HARQ进程且第二逻辑信道标识为LCH3,LCH4,则UE使用该上行CG资源仅传输LCH3和LCH4对应的上行数据,也即是,UE仅将LCH3和LCH4对应的上行数据在该上行资源上进行发送。
在t3时刻为CG index2的CG资源的位置,对应的HARQ进程为HARQ ID3,此时每个LCH都有待传输数据可以传输,但是由于HARQ ID3为去使能的HARQ且在CG index2上传输的LCH为LCH2和LCH4,UE使用该上行CG资源仅传输LCH2对应的上行数据,也即是,UE仅将LCH2对应的上行数据在该上行资源上进行发送。
在t4时刻为CG index2的CG资源的位置,对应的HARQ进程为HARQ ID4,此时每个LCH都有待传输数据可以传输,但是由于HARQ ID4为使能的HARQ且在CG index2上传输的LCH为LCH2和LCH4,UE使用该上行CG资源仅传输LCH4对应的上行数据,也即是,UE仅将LCH4对应的上行数据在该上行资源上进行发送。
需要说明的是,当第一信息包括上行CG索引标识、与上行CG索引标识对应的至少一个逻辑信道的标识和/或优先级时,即第一信息包括CG index以及在该CG index对应的CG资源上传输的逻辑信道的标识和/或优先级,例如,可以在CG index2上传输的LCH为LCH2和LCH4,其可用来限制在某个HARQ进程或每个CG资源上(如特定CG index对应的CG资源)上进行传输的LCH的标识或优先级。当然,该信息也可是一种专用指示信息而不携带于RRC中。
还需要说明的是,不同的CG资源可以对应同一个LCH ID,也可以对应不同的LCH ID。不同的CG资源对应的LCH可以是同一类型的逻辑信道,例如不同的CG资源均对应第一类型的逻辑信道,也可以对应不同类型的逻辑信道,例如一个CG资源对应的是第一逻辑信道,对另一个CG资源对应的是第二逻辑信道。
可选的,在本申请实施例中,UE可以对应CG资源以及动态授权(Dynamic Grant,DG)资源,其中,CG资源可以对应至少一个CG索引,每个CG索引可以对应至少一个HARQ进程。当以UE为粒度时,该UE对应的至少一个HARQ进程对应的HARQ功能可以均为使能状态或者均为去使能状态;当以CG资源为粒度时,与至少一个CG index上传输的CG资源对应的至少一个HARQ进程对应的HARQ功能可以均为使能状态或者均为去使能状态;当以CG index为粒度时,与每个CG index上传输的CG资源对应的至少一个HARQ进程对应的HARQ功能可以均为使能状态或者均为去使能状态;当以HARQ进程为粒度时,需要单独配置与该CG资源对应的至少一个HARQ 进程中每个HARQ进程的HARQ功能。
当以UE,CG资源和CG index为粒度时,前述第一信息可以指包括步骤301中第1项、第2项以及第5项至第13项中的任意一种。
示例的,若第一信息中指示的是CG index ID为A(A为非负整数)的上行资源对应的至少一个HARQ进程均为去使能,则在该CG index ID为A的所有上行资源上(或其对应的HARQ进程)仅传输第一逻辑信道对应的上行数据。
在第一种数据传输方法中,针对不同类型的CG资源(即type1和/或type2),在RRC信息中引入了LCH和具有不同HARQ功能的HARQ进程的映射关系,保证了不同的LCH分别在关闭HARQ功能的HARQ进程和开启HARQ功能的HARQ进程上传输,从而保证了不同业务的QoS需求。
图5示出了第二种数据传输方法的流程图,该数据传输方法中,上行资源包括上行CG资源(也可称为CG资源,该CG资源可以为type 2 CG)。该方法包括:
步骤501、接收PDCCH。
该PDCCH用于指示上行资源的激活状态,PDCCH中携带有第一信息。该第一信息可以包括其中至少一个信息项,当第一信息包括两个以上信息项时,不同的信息项可以携带在相同或不同的PDCCH中。

该DCI信令携带有第一信息,该DCI信令用于激活上行CG资源。
步骤501b、根据DCI信令激活上行CG资源。
当UE收到该资源配置信令,且收到DCI信令指示激活某个上行CG资源后,才可使用该上行CG资源进行数据传输。
可选的,第一信息可以包括如下至少一个信息项:
1)配置CG资源对应的CG index标识;
2)与终端对应的所有HARQ进程的使能状态;
3)与配置的CG资源对应的HARQ进程的数目。可选的,在配置多个CG资源时,同时配置HARQ offset;可选的,与配置的CG资源对应的HARQ进程的数目包括:与配置的CG索引对应的HARQ进程的数目。
4)与配置的CG资源对应的HARQ进程标识;可选的,与配置的CG资源对应的HARQ进程的标识包括:与配置的CG索引对应的HARQ进程的标识。
5)与配置的CG资源对应的HARQ进程中的至少一个HARQ进程的使能状态;可选的,包括:a)与上行CG资源对应的所有HARQ进程的使能状态;b)与上行CG资源对应的单个CG索引标识对应的所有HARQ进程的使能状态,所述上行CG资源对应有至少两个CG索引标识;c)与上行CG资源对应的单个HARQ进程对应的使能状态。
6)与配置的CG资源对应的处于去使能的HARQ进程标识;
7)与配置的CG资源对应的处于使能的HARQ进程标识;
8)第一逻辑信道的标识;
9)第一逻辑信道的优先级;
10)区别于第一逻辑信道的第二逻辑信道的标识;
11)区别于第一逻辑信道的第二逻辑信道的优先级。其中第二逻辑信道为禁止在处于去使能状态的HARQ进程对应的资源上进行传输的逻辑信道,或者,允许在处于使能状态的HARQ进程对应的资源上进行传输的逻辑信道。
12)上行CG索引标识、与上行CG索引标识对应的至少一个逻辑信道的标识。其中,该逻辑信道为在与上行CG索引标识对应的上行CG资源上传输的逻辑信道的标识。
13)上行CG索引标识、与上行CG索引标识对应的至少一个逻辑信道的优先级。其中,该逻辑信道为在与上行CG索引标识对应的上行CG资源上传输的逻辑信道的优先级。
可选的,该资源配置信令中可以包括第一信息中的至少一个信息项。该资源配置信令和该PDCCH共同给出完整的第一信息。
可选的,根据接收到的资源配置信令或者DCI信令配置type2 CG资源以及与该配置的type2 CG资源对应的HARQ相关参数,并配置或确定第一逻辑信道和/或第二逻辑信道。该第一逻辑信道包括允许在处于去使能状态的HARQ进程对应的资源上进行传输的逻辑信道,第二逻辑信道是禁止在处于去使能状态的HARQ进程对应的资源上进行传输的逻辑信道,或者,允许在处于使能状态的HARQ进程对应的资源上进行传输的逻辑信道。
步骤502、根据第一信息,将第一逻辑信道对应的上行传输在上行资源上进行发送。
在UE接收到PDCCH之后可以根据其中包括的DCI信令激活上行CG资源。对于已经激活的上行CG资源,UE可以根据上述第一信息中的至少一个信息项,将第一逻辑信道对应的上行传输在上行资源上进行发送。与上述步骤302类似,在本申请实施例中,上行CG资源对应的HARQ进程所具有的HARQ功能可以包括三种情况:HARQ功能为使能状态,HARQ功能为去使能状态,未设定HARQ功能。因此,步骤302可以分为以下三种情况:
在第一种情况中,在UE使用该CG资源进行新传时,若UE根据第一信息,确定该上行CG资源对应的HARQ功能为去使能状态,则UE仅将第一逻辑信息对应的上行数据和/或至少与该第一逻辑信道对应的MAC CE映射在该上行CG资源上。
在第二种情况中,在UE使用该CG资源进行新传时,若UE根据第一信息,确定该上行CG资源对应的HARQ功能为使能状态,则UE仅将第一逻辑信息对应的上行数据和/或至少与该第一逻辑信道对应的MAC CE映射在该上行CG资源上。
在第三种情况中,在UE使用该CG资源进行新传时,若UE根据该第一信息,确定该上行CG资源对应的HARQ进程未设置HARQ功能,则UE仅将第二逻辑信息对应的上行数据和/或至少与该第二逻辑信道对应的MAC CE映射在该上行CG资源上;或者,将UE将第一逻辑信道和第二逻辑信道对应的上行数据和/或至少与该逻辑信道对应的MAC CE映射在该上行CG资源上。
需要说明的是,若DCI信令中未指示第二逻辑信道,UE可以根据第一逻辑信道在总的所有逻辑信道中确定第二逻辑信道。同理,若DCI信令中未指示第一逻辑信道,UE可以根据第二逻辑信道在总的所有逻辑信道中确定第一逻辑信道。
需要说明的是,配置HARQ进程的使能状态,如配置对应CG index1的HARQ进程HARQ ID1为去使能的HARQ进程,HARQ ID2为使能的HARQ进程,也可以在专用RRC消息中配置或在DCI中指示。
图6示出了针对图5所描述的数据传输方法的一种具体实施例示意图。假设UE建立了4条上行逻辑信道,分别为LCH1,LCH2,LCH3和LCH4。
步骤b1、UE接收网络侧设备发送的资源配置信令,UE根据该资源配置信令中的至少一个信息项配置了如下内容:
两套CG资源,分别对应CG index1和CG index2,且均为type2的CG资源,其中,与CG index1的CG资源对应的2个HARQ进程,对应的HARQ ID分别为1和2。与CG index2的CG资源对应的2个HARQ进程,对应的HARQ ID分别为3和4,配置HARQ ID3为去使能的HARQ进程,HARQ ID4为使能的HARQ进程。
步骤b2、UE接收承载DCI指令的PDCCH。
该DCI信令中的第一信息指示CG index 1的CG资源激活,该过程可以包括:首先DCI信令指示CG index1的CG资源激活;然后DCI信令中的第一信息指示对应CG index1的CG资源的HARQ进程中,存在处于去使能的HARQ进程。
进一步的,指示HARQ ID1为去使能的HARQ进程,HARQ ID2为使能的HARQ进程。指示能在CG index1上传输的LCH为LCH1,LCH2,LCH3。指示第一逻辑信道标识为LCH1,LCH2,第二逻辑信道标识为LCH3,LCH4。
进一步的,可以在专用RRC消息或该DCI中指示,至少一个CG index对应的CG资源上传输的逻辑信道的标识和/或优先级,例如,可以在CG index1上传输的LCH为LCH1,LCH2和LCH3,其可用来限制在某个HARQ进程或每个CG资源上(如特定CG index对应的CG资源)上进行传输的LCH的标识和/或优先级。相应的该信息可以为第一信息中的一种,也可是一种专用指示信息。
需要说明的是,由于CG index2的CG资源未指示激活(因此图6中未示出),则UE不能使用该CG资源进行UL传输。直至后续,UE收到网络指示激活该CG index2的资源时,UE才可以使用CG index2的资源进行传输。
作为另一种实施例,配置HARQ进程的使能状态,如配置对应CG index1的HARQ进程HARQ ID1为去使能的HARQ进程,HARQ ID2为使能的HARQ进程,也可以在专用RRC消息中配置或在DCI中指示。
可选的,HARQ进程的使能状态可以为根据HARQ进程数,LCH的优先级,LCH对应数据的优先级,已建立业务QoS等信息确定。
步骤b3、根据第一信息,将第一逻辑信道对应的上行传输在上行资源上进行发送。
在t1时刻为CG index1的CG资源的位置,对应的HARQ进程为HARQ ID1,此时每个LCH都有待传输数据可以传输,但是由于HARQ ID1为去使能的HARQ进程且第一逻辑信道标识为LCH1和LCH2,则UE使用该上行CG资源仅传输LCH1和LCH2的上行数据。
在t2时刻为CG index1的CG资源的位置,对应的HARQ进程为HARQ ID2,此时每个LCH都有待传输数据可以传输,但是由于HARQ ID2为使能的HARQ进程且第二逻辑信道标识为LCH3和LCH4,但是LCH4不能在CG index1的资源上传输,UE使用该上行CG资源仅传输LCH3的上行数据。
可选的,DCI中携带的第一信息可以包括上行CG索引标识、与上行CG索引标识对应的至少一个逻辑信道的标识和/或优先级,例如,可以在CG index1上传输的LCH为LCH1,LCH2和LCH3,其可用来限制在某个HARQ进程或每个CG资源上(如特定CG index对应的CG资源)上进行传输的LCH的标识或优先级。另外,上行CG索引标识、与上行CG索引标识对应的至少一个逻辑信道的标识和/或优先级可以在专用指示信息中进行指示,例如在专用RRC消息中进行指示。
还需要说明的是,不同的CG资源可以对应同一个LCH ID,也可以对应不同的LCH ID。不同的CG资源对应的LCH可以是同一类型的逻辑信道,例如不同的CG资源均对应第一类型的逻辑信道,也可以对应不同类型的逻辑信道,例如一个CG资源对应的是第一逻辑信道,对另一个CG资源对应的是第二逻辑信道。
可选的,UE可以对应CG资源以及DG资源,其中,CG资源可以对应至少一个CG索引,每个CG索引可以对应至少一个HARQ进程。当以UE为粒度时,该UE对应的至少一个HARQ进程对应的HARQ功能可以均为使能状态或者均为去使能状态;当以CG资源为粒度时,与至少一个CG index上传输的CG资源对应的至少一个HARQ进程对应的HARQ功能可以均为使能状态或者均为去使能状态;当以CG index为粒度时,与每个CG index上传输的CG资源对应的至少一个HARQ进程对应的HARQ功能可以均为使能状态或者均为去使能状态;当以HARQ进程为粒度时,需要单独配置与该CG资源对应的至少一个HARQ进程中每个HARQ进程的HARQ功能。
当以UE,CG资源和CG index为粒度时,前述第一信息可以包括步骤501中所描述的第一信息中的至少一个信息项。
示例的,若第一信息中指示的是CG index ID为A(A为非负整数)的上行资源对应的至少一个HARQ进程均为去使能,则在该CG index ID为A的所有上行资源上(或其对应的HARQ进程)仅传输第一逻辑信道对应的上行数据。
在第二种数据传输方法中,针对类型为的type2的CG资源,在DCI信令中引入了LCH和具有不同HARQ功能的HARQ进程的映射关系,保证了不同的LCH分别在关闭HARQ功能的HARQ进程和开启HARQ功能的HARQ进程上传输,从而保证了不同业务的QoS需求。
图7示出了第三种数据传输方法的流程图,该数据传输方法中,上行资源包括DG资源,一个DG资源对应一个HARQ进程。该方法包括:
步骤701、接收上行资源的资源调度信令。
该资源调度信令携带有第一信息,该资源调度信令包括用于调度上行动态资源的下行控制信息DCI信令。该资源调度信令可以包括PDCCH。
该资源调度信令中携带有第一信息,该资源调度信令中包括至少一个信息项,该第一信息可以包括其中至少一个信息项,当第一信息包括其中两个以上信息项时,不同的信息项携带在相同或不同的资源调度信令中。以下示出了该资源调度信令中可以包括的至少一个信息项:
1)与配置的DG资源对应的HARQ进程标识;
2)与配置的DG资源对应的HARQ进程的使能状态;
3)第一逻辑信道的标识;
4)第一逻辑信道的优先级;
5)区别于第一逻辑信道的第二逻辑信道的标识;
6)区别于第一逻辑信道的第二逻辑信道的优先级,其中第二逻辑信道为禁止在处于去使能状态的HARQ进程对应的资源上进行传输的逻辑信道,或者,允许在处于使能状态的HARQ进程对应的资源上进行传输的逻辑信道;
7)与配置的DG资源对应的至少一个逻辑信道的标识。其中,与配置的DG资源对应的至少一个逻辑信道指的是在该DG资源上传输的逻辑信道。
8)与配置的DG资源对应的至少一个逻辑信道的优先级。其中,与配置的DG资源对应的至少一个逻辑信道指的是在该DG资源上传输的逻辑信道。
需要说明的是,DCI中若指示该HARQ进程的HARQ功能为去使能状态,则该DCI中指示的是第一逻辑信道的信息;DCI中若指示该HARQ进程的HARQ功能为去使能状态,则该DCI中指示的是第二逻辑信道的信息。在其他可能的实现方式中,DCI信令中若指示该HARQ进程的HARQ功能处于去使能状态,且该DCI信令中还指示第二逻辑信道,则UE可以首先根据该DCI信令指示的第二逻辑信道在总的所有逻辑信道中确定出第一逻辑信道,再将该第一逻辑信道对应的上行数据在该处于去使能状态的HARQ进程上传输。或者,DCI信令中若指示该HARQ进程的HARQ功能处于去使能状态,则UE可以指示出该HARQ进程对应的逻辑信道并将该逻辑信道标识为第一逻辑信道。本申请实施例对此不进行限制。
步骤702、根据第一信息,将第一逻辑信道对应的上行传输在上行资源上进行发送。
若网络通过DCI指示该资源为新传资源或者新指示信息(New Data Indication,NDI)翻转(0变为1,或者1变为0),则UE可以使用该DG资源进行新传传输。否则,UE使用该DG资源进程重传传输。
在本申请实施例中,第一信息可以为上述资源配置信令中包括的至少一个信息项中第2项至第6项中的至少一种。针对DG资源对应的HARQ进程所具有的HARQ功能地三种情况,步骤702可以包括以下三种情况:
在第一种情况中,若为新传资源,在UE使用该DG资源进行新传时,若UE根据第一信息,确定该上行DG资源对应的HARQ功能为去使能状态,则UE仅将第一逻辑信息对应的上行数据和/或至少与该第一逻辑信道对应的MAC CE映射在该上行CG资源上。
在第二种情况中,若为新传资源,在UE使用该DG资源进行新传时,若UE根据第一信息,确定该上行DG资源对应的HARQ功能为使能状态,则UE仅将第二逻辑信息对应的上行数据和/或至少与该第二逻辑信道的MAC CE映射在该UL CG资源上。
在第三种情况中,若为新传资源,在UE使用该DG资源进行新传时,若UE根据该第一信息,确定该上行DG资源对应的HARQ进程未设置HARQ功能,则UE仅将第二逻辑信息对应的上行数据和/或至少与该第二逻辑信道的MAC CE映射在该上行CG资源上;或者,UE将第一逻辑信道和二逻辑信息对应的上行数据和/或至少与该逻辑信道对应的MAC CE映射在该上行CG资源上。
需要说明的是,若DCI中未指示第二逻辑信道,UE可以根据第一逻辑信道在总的所有逻辑信道中确定出第二逻辑信道。同理,若DCI中未指示第一逻辑信道,UE可以根据第二逻辑信道在总的所有逻辑信道中确定出第一逻辑信道。
图8示出了针对图7所描述的数据传输方法的一种具体实施例示意图。假设UE建立了4条上行逻辑信道,分别为LCH1,LCH2,LCH3和LCH4。
步骤c1、UE接收网络侧设备发送的DCI指示信息,调度DG资源进行新传。同时在DCI中指示的信息具体包含:
1)该DG资源对应的HARQ进程标识为HARQ ID1;
2)指示HARQ ID1为去使能的HARQ进程,也即是,指示该HARQ进程类型的属性(即HARQ进程的使能状态)。
3)指示第一逻辑信道标识为LCH1以及LCH2,也即是,第一逻辑信道的信息。
4)指示能在该资源上传输的LCH为LCH1,LCH2以及LCH3,也即是,能在该DG资源上传输的LCH的属性。
步骤c2、根据第一信息,将第一逻辑信道对应的上行传输在上行资源上进行发送。
对该DG资源,此时每个LCH都有待传输数据可以传输。但是由于能在该资源上传输的LCH被指示为LCH1,LCH2,LCH3,则仅有LCH1,LCH2,LCH3的数据可以在该DG上传输。同时,HARQ进程的类型,该ID为1的HARQ进程被指示的类型为去使能的HARQ进程,且第一逻辑信道标识为LCH1和LCH2,则UE使用该DG资源,仅传输LCH1和LCH2的数据。
需要说明的是,UE也可以先判断HARQ进程类型的属性和第一逻辑信道信息,再判断指示的能在该DG资源上传输的LCH的属性,或者同时对HARQ进程类型的属性和第一逻辑信道信息以及指示的能在该资源上传输的LCH的属性进行判断,或者以其他顺序进行判断,本申请实施例在此不做限制。
还需要说明的是,在第三种数据传输方法中,资源调度信令也可以称为资源传输信令等其他信令名称,该信令用于分配上行资源,本申请对该信令的具体名称不加以限定。
该第三种数据传输方法中,针对DG资源,在DCI中引入LCH和具有不同类型HARQ功能的HARQ进程的映射关系,保证了不同的LCH分别在关闭HARQ功能的HARQ进程和开启HARQ功能的HARQ进程上传输,从而保证了不同业务的QoS需求。
