- devices such as AR and MR need built-in cameras to collect and continuously upload current scene images at a specific frequency (such as 60Hz).
- data scheduling can generally be divided into dynamic scheduling and semi-persistent scheduling.
- semi-persistent scheduling includes configuration grant scheduling and semi-persistent scheduling.
- uplink scheduling is divided into two types: dynamic scheduling transmission and configured grant (CG) scheduling-free transmission, and CG scheduling-free transmission is hereinafter referred to as CG transmission.
- CG dynamic scheduling transmission and configured grant
- CG scheduling-free transmission is hereinafter referred to as CG transmission.
- the UE sends a transmission request to the base station and reports the amount of data to be transmitted.
- the base station allocates corresponding transmission resources for the UE according to the information reported by the UE.
- Dynamic scheduling can configure different parameters for each transmission to adapt to channel state changes.
- dynamic scheduling requires blind detection of control information at the receiving end, which increases power consumption at the receiving end.
- the uplink scheduling-free transmission includes type1 and type2.
- the uplink scheduling-free transmission configuration is all completed through RRC signaling.
- the uplink scheduling-free transmission configuration is first configured by the base station through RRC signaling, and then the base station activates uplink transmission through downlink control information (DCI) signaling.
- DCI downlink control information
- the receiving end does not need to blindly detect control information.
- the configuration parameters of the CG transmission change, reactivation or reconfiguration is required, which still requires blind detection of control information at the receiving end, resulting in power consumption overhead.
- the uplink scheduling-free transmission scheme is divided into two types: type1 and type2.
- Type 1 uplink scheduling-free transmission configuration is completed through RRC signaling
- type 2 uplink scheduling-free transmission configuration is completed through RRC signaling and DCI activation signaling.
- the network device for example, base station
- the network device first configures periodic transmission resources for the terminal device through RRC signaling, and the terminal device can directly transmit on the configured resources when it needs to transmit uplink data.
- scheduling-free transmission saves time for scheduling requests and data scheduling. All parameters involved in Type1 scheduling-free transmission are configured through RRC.
- the network device For type2 uplink scheduling-free data transmission, the network device (for example, base station) first configures through RRC signaling, and then the network device (for example, base station) schedules the wireless network temporary identifier (configured scheduling radio network temporary identifier, CS- RNTI) scrambled physical downlink control channel (physical downlink control channel, PDCCH) activation signaling activates uplink transmission.
- Type2 scheduling-free transmission resource period is configured through RRC signaling, specific time-frequency resource configuration, modulation and coding strategy (modulation and coding scheme, MCS) level and multiple-input multiple-output system (multi-input multi-output, MIMO) parameters, etc. Both are indicated in the activation DCI signaling.
- the terminal device According to the cycle and offset configured by RRC, the terminal device can directly transmit in the configured transmission cycle after receiving the DCI activation signaling.
- NR also provides two scheduling methods, that is, semi-persistent scheduling (SPS) transmission for dynamic scheduling and pre-configured authorization.
- SPS semi-persistent scheduling
- dynamic scheduling the UE needs to monitor (monitor) the PDCCH all the time, and determine the scheduling signaling for the terminal through the C-RNTI information carried by the PDCCH.
- the blind detection power consumption of the UE is also relatively large.
- the base station configures the downlink SPS resource period through RRC signaling, but does not activate the SPS at this time.
- the base station Similar to the type2 process of uplink transmission, the base station sends the PDCCH scrambled by the CS-RNTI to activate or deactivate the SPS, and indicates the resource used for the first transmission of the SPS.
- the UE determines whether the downlink SPS is activated and the resource location of the subsequent SPS by monitoring the PDCCH. After the downlink SPS is activated, the UE will receive downlink transmission on the pre-configured resource position.
- the current 3GPP standard adopts the MCS based on the channel state, that is, adjusts the parameters of the MCS according to the channel state.
- the MCS parameter can be used to adjust the modulation and coding strategy of the transmitted data, and improve the reliability of data transmission at the cost of additional redundant bits.
- network devices for example, base stations
- network devices can use low-order MCS to transmit data, that is, by adding a large number of redundant bits and using low-order modulation, at the cost of reducing system transmission efficiency, ensuring Correct rate of transmitted data transmission.
- network equipment for example, a base station
- the above SPS/CG type1/2 all have the characteristics of one configuration and multiple transmissions, that is, after configuring parameters once, all data transmitted by SPS/CG adopts the configured parameters. If you want to change configuration parameters, RRC reconfiguration or DCI reactivation is required. But reconfiguration or activation will introduce additional delay. Since the DCI format used for reactivation contains a lot of fields (that is, occupies a lot of bits), but only 5 bits are used to indicate the MCS, and the remaining fields are not helpful for changing the MCS, so frequent reactivation seriously increases the overhead of system transmission. It not only affects the capacity of the system, but also increases the power consumption of DCI for blind detection reconfiguration or reactivation of terminal equipment.
- the present application proposes a method for information transmission, in order to provide reliable transmission of data while reducing detection overhead of detection control information.

本申请涉及通信领域,并且更具体地,涉及信息传输的方法和装置。The present application relates to the field of communications, and more particularly, to methods and devices for information transmission.
未来通信系统中的实时宽带通信(real-time broadband communication,RTBC)场景旨在支持大带宽和低交互时延,目标是在给定时延和一定的可靠性要求下,将带宽提升10倍,打造人与虚拟世界交互时的沉浸式体验。其中,有着超高带宽和超低时延要求的扩展现实专业版(extended reality professional,XR Pro)业务对第五代(the 5th generation,5G)移动通信技术提出了更为严峻的挑战。XR主要包含虚拟现实(virtual reality,VR)、增强现实(augmented reality,AR)以及混合现实(mixed reality,MR)等虚拟与现实交互技术。其中,在下行传输过程中,服务器的XR内容将以固定频率(例如,60Hz或120Hz)生成数据内容,并由基站侧传输给XR的终端设备。另外,由于图形生成的需要,AR和MR等设备需内置摄像头采集并以特定频率(例如,60Hz)连续上传当前场景图像。The real-time broadband communication (RTBC) scenario in the future communication system aims to support large bandwidth and low interaction delay. The goal is to increase the bandwidth by 10 times under the given delay and certain reliability requirements, creating Immersive experience when a person interacts with a virtual world. Among them, the extended reality professional (XR Pro) service with ultra-high bandwidth and ultra-low latency requirements poses a more severe challenge to the fifth generation (5G) mobile communication technology. XR mainly includes virtual reality (VR), augmented reality (augmented reality, AR) and mixed reality (mixed reality, MR) and other virtual and reality interaction technologies. Wherein, during the downlink transmission process, the XR content of the server will generate data content at a fixed frequency (for example, 60 Hz or 120 Hz), and transmit it to the XR terminal equipment by the base station side. In addition, due to the needs of graphics generation, devices such as AR and MR need built-in cameras to collect and continuously upload current scene images at a specific frequency (for example, 60Hz).
在当前的新空口(new radio,NR)中,针对上行传输和下行传输,都提供了动态调度和半静态调度两种调度方式。其中,动态调度可以为每次传输配置不同的参数,以适应信道状态的变化,但动态调度需要接收端盲检控制信息,增加了接收端的功耗开销。半静态调度具有一次配置多次使用的特点,也即,配置一次参数之后,后续的传输都采用该次配置的参数。虽然,在半静态调度下,接收端不需要盲检控制信息。但是,半静态传输的配置参数的改变,需要通过控制信息进行重配置或重新激活。在这种情况下,接收端依然需要盲检控制信息,从而带来功耗开销。In the current new radio interface (new radio, NR), two scheduling methods, dynamic scheduling and semi-persistent scheduling, are provided for uplink transmission and downlink transmission. Among them, dynamic scheduling can configure different parameters for each transmission to adapt to changes in the channel state, but dynamic scheduling requires blind detection of control information at the receiving end, which increases the power consumption of the receiving end. Semi-persistent scheduling has the feature of one-time configuration and multiple usage, that is, after parameters are configured once, subsequent transmissions will use the parameters configured this time. Although, under semi-persistent scheduling, the receiving end does not need to blindly detect control information. However, changes to configuration parameters of semi-static transmissions require reconfiguration or reactivation through control messages. In this case, the receiving end still needs to blindly detect the control information, which brings power consumption overhead.
因此,亟需一种信息传输的方法,既能使能半静态传输基于信道变化做出对应的改变以提供传输可靠性和资源利用率,又避免接收端盲检DCI带来的功耗。Therefore, there is an urgent need for a method of information transmission, which can not only enable semi-static transmission to make corresponding changes based on channel changes to improve transmission reliability and resource utilization, but also avoid power consumption caused by blind detection of DCI at the receiving end.

Since the information of the RRC layer will eventually become the information of the PHY layer, or be transformed from the information of the PHY layer, under this architecture, high-level signaling, such as RRC layer signaling, can also be considered to be sent by the DU , or, sent by DU+AAU.

5G新愿景下的实时宽带通信(real time broadband communication,RTBC)场景旨在支持支持大带宽和低交互时延,目标是在给定时延下和一定的可靠性要求下的提升带宽,打造人与虚拟世界交互时的沉浸式体验。其中,有着超高带宽和超低时延要求的扩展现实(extended reality,XR)Pro业务对当前5G提出了更为严峻的挑战。XR主要包含虚拟现实(virtual reality,VR),增强现实(augmented reality,AR)以及混合现实(mixed reality,MR)等虚拟与现实交互技术。其中,在下行传输过程中,服务器的XR内容将以固定频率(例如60Hz,120Hz)生成数据内容,并由基站侧传输给拓展现实终端设备(XR UE)。另外,由于图形生成的需要,AR和MR等设备需内置摄像头采集并以特定频率(例如60Hz)连续上传当前场景图像。The real time broadband communication (RTBC) scenario under the new vision of 5G aims to support large bandwidth and low interaction delay. Immersive experience when interacting with virtual worlds. Among them, the extended reality (XR) Pro service with ultra-high bandwidth and ultra-low latency requirements poses a more severe challenge to the current 5G. XR mainly includes virtual reality (VR), augmented reality (augmented reality, AR) and mixed reality (mixed reality, MR) and other virtual and reality interaction technologies. Among them, during the downlink transmission process, the XR content of the server will generate data content at a fixed frequency (such as 60Hz, 120Hz), and transmit it to the extended reality terminal equipment (XR UE) by the base station side. In addition, due to the needs of graphics generation, devices such as AR and MR need built-in cameras to collect and continuously upload current scene images at a specific frequency (such as 60Hz).
在NR中,数据的调度通常可以分为动态调度和半静态调度。其中,半静态调度包括配置授权调度和半持续调度。In NR, data scheduling can generally be divided into dynamic scheduling and semi-persistent scheduling. Among them, semi-persistent scheduling includes configuration grant scheduling and semi-persistent scheduling.
例如,上行链路的调度分为动态调度传输和配置授权(configured grant,CG)免调度传输两种,CG免调度传输在下文中简称为CG传输。动态调度传输,是在上行数据传输之前,UE向基站发送传输请求并上报传输的数据量。基站根据UE上报的信息为UE分配相应的传输资源。动态调度可以为每次传输配置不同的参数,以适应信道状态的变化。但是,动态调度需要接收端盲检控制信息,增加了接收端的功耗开销。配置授权免调度传输是指UE不需要每次传输时向基站发送调度请求,也不需要等待基站的上行调度许可,而是由UE在实现配置或激活的资源上自主进行周期性的上行数据的发送。上行的免调度传输包括type1和type2两种,其中,对于type1,上行免调度的传输配置全部是通过RRC信令完成的。对于type2,上行免调度的传输配置首先由基站通过RRC信令配置,然后由 基站通过下行控制信息(downlink control information,DCI)信令激活上行传输。相比于动态调度传输,在免调度传输中,接收端不需要盲检控制信息。但是,如果CG传输的配置参数发生变化,需要进行重新激活或者重配置,这依然需要接收端盲检控制信息,带来功耗开销。For example, uplink scheduling is divided into two types: dynamic scheduling transmission and configured grant (CG) scheduling-free transmission, and CG scheduling-free transmission is hereinafter referred to as CG transmission. In the dynamic scheduling transmission, before the uplink data transmission, the UE sends a transmission request to the base station and reports the amount of data to be transmitted. The base station allocates corresponding transmission resources for the UE according to the information reported by the UE. Dynamic scheduling can configure different parameters for each transmission to adapt to channel state changes. However, dynamic scheduling requires blind detection of control information at the receiving end, which increases power consumption at the receiving end. Configuring authorized scheduling-free transmission means that the UE does not need to send a scheduling request to the base station every time it transmits, nor does it need to wait for the uplink scheduling permission from the base station, but the UE independently performs periodic uplink data on the resources configured or activated send. The uplink scheduling-free transmission includes type1 and type2. For type1, the uplink scheduling-free transmission configuration is all completed through RRC signaling. For type2, the uplink scheduling-free transmission configuration is first configured by the base station through RRC signaling, and then the base station activates uplink transmission through downlink control information (DCI) signaling. Compared with dynamic scheduling transmission, in scheduling-free transmission, the receiving end does not need to blindly detect control information. However, if the configuration parameters of the CG transmission change, reactivation or reconfiguration is required, which still requires blind detection of control information at the receiving end, resulting in power consumption overhead.
如图2所示,上行免调度传输方案分为type1和type2两种。Type1的上行免调度的传输配置是通过RRC信令完成的,type2的上行免调度的传输配置是通过RRC信令和DCI激活信令共同完成的。对于type1的上行免调度数据传输,网络设备(例如,基站)先通过RRC信令为终端设备配置周期性的传输资源,终端设备有上行数据需要传输时可以直接在配置的资源上进行传输。相对于基于调度的数据传输,免调度传输省去了调度请求和数据调度的时间。Type1免调度传输涉及的所有参数,均通过RRC配置。As shown in Figure 2, the uplink scheduling-free transmission scheme is divided into two types: type1 and type2. Type 1 uplink scheduling-free transmission configuration is completed through RRC signaling, type 2 uplink scheduling-free transmission configuration is completed through RRC signaling and DCI activation signaling. For type1 uplink scheduling-free data transmission, the network device (for example, base station) first configures periodic transmission resources for the terminal device through RRC signaling, and the terminal device can directly transmit on the configured resources when it needs to transmit uplink data. Compared with scheduling-based data transmission, scheduling-free transmission saves time for scheduling requests and data scheduling. All parameters involved in Type1 scheduling-free transmission are configured through RRC.
对于type2的上行免调度数据传输,由网络设备(例如,基站)先通过RRC信令配置,然后由网络设备(例如,基站)通过配置调度无线网络临时标识(configured scheduling radio network temporary identifier,CS-RNTI)加扰的物理下行控制信道(physical downlink control channel,PDCCH)激活信令激活上行传输。Type2免调度传输资源周期通过RRC信令配置,具体的时频资源配置,调制与编码策略(modulation and coding scheme,MCS)等级和多输入多输出系统(multi-input multi-output,MIMO)参数等都在激活DCI信令中指示。终端设备按照RRC配置的周期和偏移,在收到DCI激活信令后,可在配置的传输周期上直接进行传输。For type2 uplink scheduling-free data transmission, the network device (for example, base station) first configures through RRC signaling, and then the network device (for example, base station) schedules the wireless network temporary identifier (configured scheduling radio network temporary identifier, CS- RNTI) scrambled physical downlink control channel (physical downlink control channel, PDCCH) activation signaling activates uplink transmission. Type2 scheduling-free transmission resource period is configured through RRC signaling, specific time-frequency resource configuration, modulation and coding strategy (modulation and coding scheme, MCS) level and multiple-input multiple-output system (multi-input multi-output, MIMO) parameters, etc. Both are indicated in the activation DCI signaling. According to the cycle and offset configured by RRC, the terminal device can directly transmit in the configured transmission cycle after receiving the DCI activation signaling.
另外,在下行传输中,NR也提供了两种调度方式,即为动态调度和预配置授权的半持续调度(semi-perisistent scheduling,SPS)传输。在动态调度中,UE需要一直监测(monitor)PDCCH,并通过PDCCH携带的C-RNTI信息来确定针对本终端的调度信令。UE的盲检功耗也是比较大的。在预配置授权的SPS传输中,基站会通过RRC信令配置下行SPS资源周期,但此时并不激活SPS。与上行传输的type2过程类似,基站发送经过CS-RNTI加扰的PDCCH用于激活或去激活SPS,并指示SPS的首次传输使用的资源。UE通过监测PDCCH来确定下行SPS是否被激活,以及后续SPS的资源位置。当下行的SPS被激活之后,UE会在预配置的资源位置上接收下行传输。In addition, in downlink transmission, NR also provides two scheduling methods, that is, semi-persistent scheduling (SPS) transmission for dynamic scheduling and pre-configured authorization. In dynamic scheduling, the UE needs to monitor (monitor) the PDCCH all the time, and determine the scheduling signaling for the terminal through the C-RNTI information carried by the PDCCH. The blind detection power consumption of the UE is also relatively large. In the SPS transmission of the pre-configuration authorization, the base station configures the downlink SPS resource period through RRC signaling, but does not activate the SPS at this time. Similar to the type2 process of uplink transmission, the base station sends the PDCCH scrambled by the CS-RNTI to activate or deactivate the SPS, and indicates the resource used for the first transmission of the SPS. The UE determines whether the downlink SPS is activated and the resource location of the subsequent SPS by monitoring the PDCCH. After the downlink SPS is activated, the UE will receive downlink transmission on the pre-configured resource position.
由于在无线传输中,空口信道的变化极易导致传输的信号产生误码。为解决该问题,当前3GPP标准采用基于信道状态的MCS,即根据信道状况调整MCS的参数。MCS参数可以用于调整传输数据的调制和编码策略,以附加额外冗余比特为代价,提升数据的传输可靠性。具体地,当信道状态较差时,网络设备(例如,基站)可采用低阶MCS来传输数据,即通过附加多量冗余比特以及采用低阶调制的方式,以降低系统传输效率为代价,保证传输数据传输的正确率。当信道状态较好时,网络设备(例如,基站)可采用高阶MCS传输信号,即采用高阶调制方式,并附加少量冗余比特的方式提升带宽效率。In wireless transmission, changes in air interface channels can easily lead to bit errors in transmitted signals. In order to solve this problem, the current 3GPP standard adopts the MCS based on the channel state, that is, adjusts the parameters of the MCS according to the channel state. The MCS parameter can be used to adjust the modulation and coding strategy of the transmitted data, and improve the reliability of data transmission at the cost of additional redundant bits. Specifically, when the channel state is poor, network devices (for example, base stations) can use low-order MCS to transmit data, that is, by adding a large number of redundant bits and using low-order modulation, at the cost of reducing system transmission efficiency, ensuring Correct rate of transmitted data transmission. When the channel state is good, network equipment (for example, a base station) can use high-order MCS to transmit signals, that is, use high-order modulation and add a small amount of redundant bits to improve bandwidth efficiency.
上述的SPS/CG type1/2都具有一次配置,多次传输的特点,即配置一次参数后,所有SPS/CG传输的数据都采用所配置的参数。若希望改变配置参数,需要RRC重新配置或DCI重激活。但重新配置或激活都会引入额外的时延。由于用于重激活的DCI格式含有很多字段(即占用很多比特数),但其中仅有5比特用于指示MCS,其余字段对更改MCS没有任何帮助,因此频繁重激活严重增加系统传输的开销,不仅影响系统的容量,同时也会增加终端设备盲检重配置或重激活的DCI的功耗。The above SPS/CG type1/2 all have the characteristics of one configuration and multiple transmissions, that is, after configuring parameters once, all data transmitted by SPS/CG adopts the configured parameters. If you want to change configuration parameters, RRC reconfiguration or DCI reactivation is required. But reconfiguration or activation will introduce additional delay. Since the DCI format used for reactivation contains a lot of fields (that is, occupies a lot of bits), but only 5 bits are used to indicate the MCS, and the remaining fields are not helpful for changing the MCS, so frequent reactivation seriously increases the overhead of system transmission. It not only affects the capacity of the system, but also increases the power consumption of DCI for blind detection reconfiguration or reactivation of terminal equipment.

具体地,可以将经过第二调制方式和/或第二编码方式处理后的控制信息表示为A,其码长表示为|A|,采用正交相移键控(quadrature phase shift keying,QPSK)的编码方式下,则其所需RE的个数为B=ceil(|A|/2),其中,ceil表示向上取整。定义第一物理共享信道中的第一个未承载DM-RS的符号为第一符号,定义未承载PT-RS的资源单元RE为第一RE,确定第一RE的数量E。Specifically, the control information processed by the second modulation method and/or the second encoding method can be represented as A, and its code length is represented by |A|, using quadrature phase shift keying (quadrature phase shift keying, QPSK) In the encoding mode of , the number of REs required is B=ceil(|A|/2), where ceil represents rounding up.

如图5所示,以半持续调度SPS的下行传输为例,物理下行控制信道(physical downlink control channel,PDCCH)所占的符号数量为2,即图5中的符号0和符号1,第一物理共享信道,例如物理下行共享信道(physical downlink shared channel,PDSCH),采用mapping type A的映射方式,只有一个DM-RS,且DM-RS为type1,位置于符号2上,传输SPS数据的天线端口号为1000,第一物理共享信道所对应时域资源为符号2-13,对应频域资源为3个资源块(resource block,RB),即每个符号包含36个RE,编号从0-35,该图例不包括PT-RS信号。假设控制信息包含5比特MCS经过第二调制方式为正交相位调制和第二编码方式为(32,K)里德-穆勒编码处理后所需的RE数量B为16。根据上述规则,PDSCH所占符号为2-13,可以初步假设第一符号为符号2。而在图5中,符号2用于承载DM-RS信号,因此符号2中无第一RE,确定第一符号为符号3。符号3不为DM-RS所占符号,且该符号上未映射任何参考信号,因此该符号上第一RE为该符号所有RE,即第一RE的数量为36。通过计算,控制信息所需要的RE数量B为16,因为16小于36,因此确定第一频域映射间隔为d=floor(36/16)=2,即在符号3上,每隔2个RE映射一个控制信息所需的RE。如图5中所示,可以从符号3中编号0的RE开始映射,则该MCS控制信息映射在PDSCH的符号3上的编号为0、2、6、8、10、12、14、16、18、20、22、24、28、30的RE上。As shown in Figure 5, taking the downlink transmission of the semi-persistent scheduling SPS as an example, the number of symbols occupied by the physical downlink control channel (PDCCH) is 2, that is, symbol 0 and symbol 1 in Figure 5, the first Physical shared channel, such as physical downlink shared channel (PDSCH), adopts mapping type A mapping method, only one DM-RS, and DM-RS is type1, located on symbol 2, the antenna for transmitting SPS data The port number is 1000, the time-domain resources corresponding to the first physical shared channel are symbols 2-13, and the corresponding frequency-domain resources are 3 resource blocks (resource blocks, RBs), that is, each symbol contains 36 REs, numbered from 0- 35. The illustration does not include PT-RS signals. Assuming that the control information includes 5-bit MCS, the number B of REs required after the second modulation method is quadrature phase modulation and the second coding method is (32, K) Reed-Muller coding is 16. According to the above rules, the symbols occupied by the PDSCH are 2-13, and it can be preliminarily assumed that the first symbol is symbol 2. However, in FIG. 5 , symbol 2 is used to carry a DM-RS signal, so there is no first RE in symbol 2 , and the first symbol is determined to be symbol 3 . Symbol 3 is not occupied by a DM-RS, and no reference signal is mapped on this symbol, so the first RE on this symbol is all REs of this symbol, that is, the number of first REs is 36. By calculation, the number B of REs required for control information is 16, because 16 is less than 36, so it is determined that the first frequency domain mapping interval is d=floor(36/16)=2, that is, on symbol 3, every 2 REs RE needed to map a control message. As shown in Figure 5, the mapping can start from RE number 0 in symbol 3, and the numbers of the MCS control information mapped on symbol 3 of PDSCH are 0, 2, 6, 8, 10, 12, 14, 16, 18, 20, 22, 24, 28, 30 on RE.
在完成控制信息到第一物理共享信道的映射后,采用速率匹配的方式将SPS数据映射至该第一物理共享信道的第二RE上。示例性地,以图5为例,第二RE为符号2-13上未承载控制信息和DM-RS的RE。因为图5中天线端口号为1000,所以SPS数据从符号2开始按照先频域后时域的顺序映射至第一物理共享信道上,即SPS数据先映射至第一物理共享信道中符号2中编号为1、3、5、7、9、11、13、15、17、19、21、23、25、27、29、31、33、35的RE上,然后映射至符号3上编号为1、3、5、7、9、11、13、15、17、19、21、23、25、27、29、31、32、33、34、35的RE上。之后,SPS数据未映射的数据将按照先频域后时域的顺序映射至第一物理共享信道上,如映射至符号4的编号为0-35的RE 上后,再继续映射至符号6的编号为0-35的RE上,直至SPS数据全部映射完成。需要注意的是,当采用高码分复用(code division multiplexing,CDM)组号或高天线端口号进行信息传输时,第二RE不包括低CDM组号或低天线端口号的DM-RS所对应的RE。例如,若图5中的第一物理共享信道采用天线端口1002/1003传输数据,则对于的DM-RS出现的位置为符号2上编号1、3、5、7、9、11、13、15、17、19、21、23、25、29、31、33、35的RE,此时符号2上的用于天线端口1000和1001的DM-RS所占的RE,即0、2、6、8、10、12、14、16、18、20、22、24、28、30、32、34,不用于承载任何数据。在该情景下,第一物理共享信道中只有符号3-13有第二RE,因此SPS数据将从符号3开始按照先频域后时域的顺序复用至第一物理共享信道中。After the mapping of the control information to the first physical shared channel is completed, the SPS data is mapped to the second RE of the first physical shared channel in a rate matching manner. Exemplarily, taking FIG. 5 as an example, the second RE is an RE that does not carry control information and DM-RS on symbols 2-13. Because the antenna port number in Figure 5 is 1000, the SPS data is mapped to the first physical shared channel starting from symbol 2 in the order of the frequency domain and then the time domain, that is, the SPS data is first mapped to symbol 2 in the first physical shared channel On REs numbered 1, 3, 5, 7, 9, 11, 13, 15, 17, 19, 21, 23, 25, 27, 29, 31, 33, 35, and then mapped to symbol 3 numbered 1 , 3, 5, 7, 9, 11, 13, 15, 17, 19, 21, 23, 25, 27, 29, 31, 32, 33, 34, 35 RE. After that, the unmapped data of the SPS data will be mapped to the first physical shared channel in the order of the frequency domain first and then the time domain, for example, after being mapped to the RE numbered 0-35 of the symbol 4, and then continue to be mapped to the symbol 6 On the REs numbered 0-35, until all the SPS data is mapped. It should be noted that when a high code division multiplexing (CDM) group number or a high antenna port number is used for information transmission, the second RE does not include the DM-RS with a low CDM group number or a low antenna port number. Corresponding RE. For example, if the first physical shared channel in Figure 5 uses the antenna port 1002/1003 to transmit data, then the position where the DM-RS appears is the number 1, 3, 5, 7, 9, 11, 13, 15 on symbol 2 , 17, 19, 21, 23, 25, 29, 31, 33, and 35 REs, at this time, the REs occupied by the DM-RS used for antenna ports 1000 and 1001 on symbol 2, that is, 0, 2, 6, 8, 10, 12, 14, 16, 18, 20, 22, 24, 28, 30, 32, 34, not used to carry any data. In this scenario, only symbols 3-13 in the first physical shared channel have the second RE, so the SPS data will be multiplexed into the first physical shared channel starting from symbol 3 in the order of first frequency domain and then time domain.
情形2 Scenario 2
当控制信息所需的RE数量B较多时,可能还需要将控制信息的数据映射至第一物理共享信道上的第二符号上,其中,第二符号是第一符号的相邻的未承载控制信息和DM-RS的符号。以情景1的参数为背景,如图6所示,与图5中不同的是,假设控制信息包含5比特MCS经过第二调制方式为正交相位调制,第二编码方式为6比特CRC和1/8极化码,编码后的控制信息需要的RE数量B为44。根据情形1中所述规则,确定第一符号为符号3。因为第一符号,即符号3,不包含任何参考信号,符号3的第一RE数量为36。又因为符号3中第一RE数量小于控制信息所需的RE数量B,因此第一频域间隔为1,即在符号3上的每个RE映射一个控制信息所需的RE。当符号3映射完毕后,控制信息未映射的RE数量为8,因此还需要将控制信息映射至第二符号上。根据第二符号为第一符号的相邻的未承载控制信息和DM-RS的符号的规则,确定第二符号为图6中符号4,且符号4中第一RE的数量为36,因为8小于36,因此确定第二频域映射间隔为d=floor(36/8)=4,即在符号4上,每隔4个RE映射一个控制信息所需的RE。如图6中所示,可以从编号0的RE开始映射,则该MCS控制信息映射在第一物理共享信道的符号4上的编号为0、4、8、12、16、20、24、28的RE上。When the number B of REs required for the control information is large, it may be necessary to map the data of the control information to the second symbol on the first physical shared channel, where the second symbol is the adjacent uncarried control of the first symbol Symbols for information and DM-RS. Taking the parameters of Scenario 1 as the background, as shown in Figure 6, the difference from Figure 5 is that the control information contains 5-bit MCS and the second modulation method is quadrature phase modulation, and the second encoding method is 6-bit CRC and 1 /8 polar code, the number B of REs required for the coded control information is 44. According to the rules described in case 1, the first symbol is determined to be symbol 3. Since the first symbol, symbol 3, does not contain any reference signal, the first number of REs for symbol 3 is 36. And because the first number of REs in symbol 3 is smaller than the number B of REs required for control information, the first frequency interval is 1, that is, each RE on symbol 3 maps one RE required for control information. After symbol 3 is mapped, the number of REs to which the control information is not mapped is 8, so the control information needs to be mapped to the second symbol. According to the rule that the second symbol is an adjacent symbol that does not carry control information and DM-RS of the first symbol, it is determined that the second symbol is symbol 4 in Figure 6, and the number of first REs in symbol 4 is 36, because 8 is less than 36, so it is determined that the second frequency domain mapping interval is d=floor(36/8)=4, that is, on symbol 4, every 4 REs are mapped to an RE required for control information. As shown in Figure 6, the mapping can start from RE number 0, then the numbers of the MCS control information mapped on symbol 4 of the first physical shared channel are 0, 4, 8, 12, 16, 20, 24, 28 on the RE.
在完成控制信息到第一物理共享信道的映射后,采用速率匹配的方式将SPS数据映射至该第一物理共享信道的第二RE上。以图6为例,第二RE为符号2-13上未承载控制信息和DM-RS的RE。因此,SPS数据从符号2开始按照先频域后时域的顺序映射至第一物理共享信道上,具体流程可以参考情景1。需要注意的是,当采用CDM组号或高天线端口号进行信息传输时,第二RE不包括低CDM组号或低天线端口号的DM-RS所对应的RE。例如,若图5中的第一物理共享信道采用天线端口1002/1003传输数据,符号2上的DM-RS占用的RE为1、3、5、7、9、11、13、15、17、19、21、23、25、29、31、33、35,此时符号2上的用于天线端口1000和1001的DM-RS所占的RE,即0、2、6、8、10、12、14、16、18、20、22、24、28、30、32、34,不用于承载任何数据。在该情景下,图6中第一物理共享信道中只有符号4-13有第二RE,因此SPS数据将从符号4开始按照先频域后时域的顺序复用至PSCH中。示例性地,SPS数据先映射至符号4中编号为1、2、3、5、6、7、9、10、11、13、14、15、17、18、19、21、22、23、25、26、27、29、30、31、32、33、34、35的RE上,SPS数据未映射的数据再继续映射至符号5-13的第二RE上,此处不再赘述。After the mapping of the control information to the first physical shared channel is completed, the SPS data is mapped to the second RE of the first physical shared channel in a rate matching manner. Taking FIG. 6 as an example, the second RE is an RE that does not carry control information and DM-RS on symbols 2-13. Therefore, starting from symbol 2, the SPS data is mapped to the first physical shared channel in the frequency domain first and then the time domain, and the specific process can refer to scenario 1. It should be noted that when a CDM group number or a high antenna port number is used for information transmission, the second RE does not include REs corresponding to DM-RSs with a low CDM group number or a low antenna port number. For example, if the first physical shared channel in Figure 5 uses antenna port 1002/1003 to transmit data, the REs occupied by the DM-RS on symbol 2 are 1, 3, 5, 7, 9, 11, 13, 15, 17, 19, 21, 23, 25, 29, 31, 33, 35, at this time, the REs occupied by the DM-RS used for antenna ports 1000 and 1001 on symbol 2, that is, 0, 2, 6, 8, 10, 12 , 14, 16, 18, 20, 22, 24, 28, 30, 32, 34 are not used to carry any data. In this scenario, only symbols 4-13 in the first physical shared channel in Figure 6 have the second RE, so the SPS data will be multiplexed into the PSCH starting from symbol 4 in the order of frequency domain and then time domain. Exemplarily, the SPS data is first mapped to symbols 4 numbered 1, 2, 3, 5, 6, 7, 9, 10, 11, 13, 14, 15, 17, 18, 19, 21, 22, 23, On the REs 25, 26, 27, 29, 30, 31, 32, 33, 34, and 35, the unmapped data of the SPS data is further mapped to the second REs of the symbols 5-13, which will not be repeated here.
情形3 Scenario 3
该情形下考虑第一物理共享信道中配置有额外的DM-RS的场景。如图7所示,以半持续调度SPS的下行传输为例,控制信道PDCCH所占的符号数量为2,即图7中的符号0和符号1,PDSCH采用mapping type A的映射方式,有两个DM-RS,位置于符号2和符号11上,传输SPS数据的天线端口号为1000,PDSCH所对应时域资源为符号2-13,对应频域资源为3个RB,即每个符号包含36个RE,编号从0-35,该图例不包括PT-RS信号。In this situation, a scenario in which an additional DM-RS is configured in the first physical shared channel is considered. As shown in Figure 7, taking the downlink transmission of semi-persistent scheduling SPS as an example, the number of symbols occupied by the control channel PDCCH is 2, that is, symbol 0 and symbol 1 in Figure 7, and PDSCH adopts the mapping type A mapping method, there are two DM-RS, located on symbols 2 and 11, the antenna port number for transmitting SPS data is 1000, the time domain resources corresponding to PDSCH are symbols 2-13, and the corresponding frequency domain resources are 3 RBs, that is, each symbol contains 36 REs, numbered from 0-35, the legend does not include PT-RS signals.
为便于与情形2进行对比,假设经过第二调制和/或第二编码方式处理后的控制信息为需要占用44个RE,一种可能的映射方式为,确定第一符号为与前置DM-RS所在的符号2相邻的符号3,将控制信息按照第一频域间隔等于1个RE进行映射,当符号3映射完毕后,控制信息未映射的数据数量为8,因此还需要将控制信息映射至第二符号上。根据第二符号为第一符号的相邻的未承载控制信息和DM-RS的符号的规则,确定第二符号为图6中符号4,且符号4中第一RE的数量为36,因此确定第二频域映射间隔为d=floor(36/8)=4,即在符号4上,每隔4个RE映射一个控制信息所需的RE。另一种可能的映射方式中,第一符号的个数可能为多个,如图7所示,确定第一符号为与前置DM-RS所在的符号2相邻的符号3以及与后置DM-RS所在的符号11相邻的10(或12),且符号10(或12)中第一RE的数量为36,因此确定第一频域映射间隔为d=floor(36/8)=4,即在符号10(或12)上,每隔4个RE映射一个控制信息所需的RE,由此可以将控制信息所需的RE分别根据第一频域映射间隔为1个RE和第一频域映射间隔为4个RE映射至符号3和符号10(或12)中。For the convenience of comparison with Case 2, assuming that the control information processed by the second modulation and/or the second coding method needs to occupy 44 REs, a possible mapping method is to determine that the first symbol is the same as the pre-DM- The symbol 3 adjacent to the symbol 2 where the RS is located maps the control information according to the first frequency domain interval equal to 1 RE. After the symbol 3 is mapped, the number of unmapped data of the control information is 8, so the control information also needs to be mapped Mapped onto the second symbol. According to the rule that the second symbol is adjacent to the first symbol that does not carry control information and DM-RS symbols, it is determined that the second symbol is symbol 4 in Figure 6, and the number of first REs in symbol 4 is 36, so it is determined The second frequency-domain mapping interval is d=floor(36/8)=4, that is, on symbol 4, every 4 REs are mapped to an RE required for control information. In another possible mapping method, the number of the first symbol may be multiple, as shown in Figure 7, the first symbol is determined to be the symbol 3 adjacent to the symbol 2 where the pre-DM-RS is located and the The symbol 11 where the DM-RS is located is adjacent to 10 (or 12), and the number of first REs in the symbol 10 (or 12) is 36, so the first frequency domain mapping interval is determined as d=floor(36/8)= 4. That is, on symbol 10 (or 12), every 4 REs are mapped to an RE required for control information, so that the REs required for control information can be divided into 1 RE and the 1st frequency domain mapping interval according to the first frequency domain. A frequency domain mapping interval is 4 REs are mapped to symbol 3 and symbol 10 (or 12).
可选地,还可以根据符号排序信息来确定控制信息映射至第一物理共享信道的符号的符号顺序,例如,为提升解码可靠性,可按照符号序列临近一个或多个承载DM-RS的符号的方式排序(如,该符号排序为3、10、12、4、5、6、7、8、9、13),又例如,为减小解码时延,可按照顺序排序(如,该符号排序为3、4、5、6、7、8、9、10、12、13),本申请不对其进行限定。例如,当符号排序为3、10、12、4、5、6、7、8、9、13,且DM-RS所在的符号为符号2和符号11时,符号3、10、12为第一符号,符号4、5、6、7、8、9、13为第二符号,将控制信息先以第一频域映射间隔为1个RE映射至符号3上,若有控制信息还有未映射数据,则将控制信息未映射的数据继续按照第一频域映射间隔映射至符号10上。当完成控制信息到符号10的映射后,若控制信息还有未映射数据,则继续将该控制信息的未映射数据映射至符号12上,直至控制信息的全部映射至第一物理共享信道上。Optionally, the symbol sequence of the symbols that control information is mapped to the first physical shared channel may also be determined according to the symbol sequence information. For example, to improve decoding reliability, one or more symbols carrying DM-RS may be adjacent to each other according to the symbol sequence (for example, the symbols are sorted as 3, 10, 12, 4, 5, 6, 7, 8, 9, 13), and for example, in order to reduce the decoding delay, they can be sorted in order (for example, the symbols The sequence is 3, 4, 5, 6, 7, 8, 9, 10, 12, 13), which is not limited in this application. For example, when the symbols are sorted as 3, 10, 12, 4, 5, 6, 7, 8, 9, 13, and the symbols where the DM-RS is located are symbols 2 and 11, symbols 3, 10, and 12 are the first Symbols, symbols 4, 5, 6, 7, 8, 9, and 13 are the second symbols, and the control information is first mapped to symbol 3 with the first frequency domain mapping interval as 1 RE. If there is control information, there is still unmapped data, the data that is not mapped to the control information is continuously mapped to symbols 10 according to the first frequency domain mapping interval. After the mapping of the control information to the symbol 10 is completed, if there is unmapped data in the control information, continue to map the unmapped data of the control information to the symbol 12 until all the control information is mapped to the first physical shared channel.
情形4 Situation 4
该情形下考虑第一物理共享信道中包含PT-RS的场景。当第一物理共享信道中配置有PT-RS时,需要首先确定PT-RS的分布,即首先确定PT-RS的时域密度和频域密度,其中PT-RS的频域密度与分配的RB数量相关,而PT-RS的时域密度是根据MCS确定的。In this situation, a scenario in which the PT-RS is included in the first physical shared channel is considered. When PT-RS is configured in the first physical shared channel, it is necessary to first determine the distribution of PT-RS, that is, first determine the time-domain density and frequency-domain density of PT-RS, where the frequency-domain density of PT-RS is related to the allocated RB Quantity related, while the time domain density of PT-RS is determined according to MCS.
在一些实施例中,当第一物理共享信道中包含PT-RS时,需要首先确定PT-RS的分布,即首先确定PT-RS的时域密度以及对应物理共享信道所分配的资源块RB的数量。其中,PT-RS的时域密度与MCS参数的关系如表1所示,PT-RS的频域密度与带宽的关系如表2所示。In some embodiments, when the first physical shared channel contains PT-RS, it is necessary to first determine the distribution of PT-RS, that is, first determine the time domain density of PT-RS and the resource block RB allocated to the corresponding physical shared channel. quantity. Table 1 shows the relationship between the time-domain density of the PT-RS and the MCS parameters, and Table 2 shows the relationship between the frequency-domain density and the bandwidth of the PT-RS.

Among them, some fields of PT-RS configuration can be as follows:
具体地,第二配置信息包括或本身即为上述PT-RS下行配置ptrs-downlinkConfig,本申请可以在字段中增加新字段timeDensitypreset,用于指示PT-RS符号的时域密度,发送端设备(即第二通信装置)将该第二配置信息发送接收端设备(即第一通信装置),接收端设备可以根据该第一配置信息中的时域密度timeDensitypreset参数以及频域密度freqnecyDensity参数确定PT-RS符号的时域间隔和频域间隔,以便于快速、准确的确定PT-RS符号的位置分布。Specifically, the second configuration information includes or itself is the above-mentioned PT-RS downlink configuration ptrs-downlinkConfig, and the present application may add a new field timeDensitypreset in the field, which is used to indicate the time domain density of the PT-RS symbol, and the sending end device (ie The second communication device) sends the second configuration information to the receiving end device (that is, the first communication device), and the receiving end device can determine the PT-RS according to the time domain density timeDensitypreset parameter and the frequency domain density freqnecyDensity parameter in the first configuration information The time domain interval and the frequency domain interval of symbols are used to quickly and accurately determine the position distribution of PT-RS symbols.

在本申请中,半静态调度的RB数量由激活控制信息所指示,因此可以认为是一个已知参量,而由于每次SPS传输的MCS由第一物理共享信道中的控制信息所指示,因此MCS对于第一通信装置(接收端)来说是一个未知参数,若继续采用上述技术,会导致第一通信装置(接收端)无法解析PT-RS。In this application, the number of RBs for semi-persistent scheduling is indicated by the activation control information, so it can be considered as a known parameter, and since the MCS of each SPS transmission is indicated by the control information in the first physical shared channel, the MCS It is an unknown parameter for the first communication device (receiving end). If the above technology is continued to be used, the first communication device (receiving end) will not be able to parse the PT-RS.
因此,在该情形下,本申请实施例中第二通信装置(发送端)可以根据PT-RS的预设时域密度来确定PT-RS在第一物理共享信道上的分布,并将该预设时域密度发送给第一通信装置(接收端),这样可以保证第一通信装置(接收端)正常解析PT-RS。Therefore, in this situation, in the embodiment of the present application, the second communication device (transmitter) can determine the distribution of PT-RS on the first physical shared channel according to the preset time domain density of PT-RS, and use the preset It is assumed that the time domain density is sent to the first communication device (receiving end), which can ensure that the first communication device (receiving end) parses the PT-RS normally.

这样,第一通信装置可以根据PT-RS的预设时域密度确定PT-RS的位置,从而正确解析PT-RS。In this way, the first communication device can determine the position of the PT-RS according to the preset time domain density of the PT-RS, so as to correctly resolve the PT-RS.
其中,PT-RS的预设时域密度不同于基于MCS设定的门限值Among them, the preset time domain density of PT-RS is different from the threshold value set based on MCS
在本申请实施例中,以半持续调度SPS的下行传输为例,物理共享信道一共包括3个RB,对应的子载波编号为0至35,PDCCH占用的符号为0和1,物理共享信道占用的符号为2到13,频域密度K
PT-RS=2,时域密度L
PT-RS=2,采用偏移00,DM-RS端口号为0,DM-RS配置类型为1,因此确定PT-RS所在RB中的起始资源单元
若n
RNTI=0,根据公式(1)确定PT-RS的起始RB
为0。
In the embodiment of this application, taking the downlink transmission of semi-persistent scheduling SPS as an example, the physical shared channel includes 3 RBs in total, the corresponding subcarrier numbers are 0 to 35, the symbols occupied by PDCCH are 0 and 1, and the physical shared channel occupies The symbols are 2 to 13, the frequency domain density K PT-RS = 2, the time domain density L PT-RS = 2, the offset 00 is used, the DM-RS port number is 0, and the DM-RS configuration type is 1, so determine The starting resource unit in the RB where the PT-RS is located If n RNTI =0, determine the starting RB of the PT-RS according to formula (1) is 0.
因此,如图8中所示,可以确定PT-RS分别位于第0个和第2个RB上第0个子载波上,即第0个和第24个子载波上。另外,因为时域密度L
PT-RS=2,即在第0个和第24子载波上,从第一个可用PDSCH符号的RE上开始,每隔2个符号映射一个PT-RS符号。
Therefore, as shown in FIG. 8 , it can be determined that the PT-RS is located on the 0th subcarrier on the 0th and the second RB, that is, on the 0th and the 24th subcarrier respectively. In addition, because the time-domain density L PT-RS =2, that is, on the 0th and 24th subcarriers, starting from the RE of the first available PDSCH symbol, every 2 symbols are mapped to a PT-RS symbol.
在本申请中PT-RS分布在第一物理共享信道的符号4、6、8、10、12上的编号为0和24的RE上。In this application, the PT-RS is distributed on REs numbered 0 and 24 on symbols 4, 6, 8, 10, and 12 of the first physical shared channel.
假设第二调制方式为正交相位调制,第二编码方式为6比特CRC和1/8极化码,编码后的控制信息需要的RE为44。根据上述规则,确定第一符号为符号3,且根据上述PT-RS的时域密度和频域密度的分布方式,可以确定符号3上未映射任何PT-RS参考信号,因此确定符号3上第一RE的数量为36。根据情景1中所述方法,确定第一频域映射间隔为1,即在符号3上,每隔1个RE映射一个控制信息所需的RE。当符号3映射完毕后,控制信息未映射的RE数量为8,根据第二符号为第一符号的相邻的未承载控制信息和DM-RS的符号的规则,可以确定第二符号为第一物理共享信道中的符号4。由于符号4上映射了2个PT-RS信号,因此符号4上第一RE的数量为34。因为8小于34,因此确定第二频域映射间隔为d=floor(34/8)=4,即在符号4上,每隔4个RE映射一个控制信息所需的RE。因为编号为0的RE被PT-RS所占用,因此控制信息映射的RE可以从编号为1的RE开始映射,则该MCS控制信息映射在PDSCH的符号4上的编号为1、5、9、13、17、21、25、29的RE上。Assume that the second modulation mode is quadrature phase modulation, the second encoding mode is 6-bit CRC and 1/8 polar code, and the coded control information requires 44 REs. According to the above rules, it is determined that the first symbol is symbol 3, and according to the distribution of the above-mentioned PT-RS time domain density and frequency domain density, it can be determined that no PT-RS reference signal is mapped on symbol 3, so it is determined that the first symbol on symbol 3 The number of one RE is 36. According to the method described in Scenario 1, the first frequency-domain mapping interval is determined to be 1, that is, on symbol 3, every other RE is mapped to an RE required for control information. After symbol 3 is mapped, the number of REs to which the control information is not mapped is 8. According to the rule that the second symbol is adjacent to the first symbol that does not carry control information and DM-RS symbols, it can be determined that the second symbol is the first Symbol 4 in the physical shared channel. Since two PT-RS signals are mapped on symbol 4, the number of first REs on symbol 4 is 34. Since 8 is less than 34, it is determined that the second frequency-domain mapping interval is d=floor(34/8)=4, that is, on symbol 4, every 4 REs are mapped to an RE required for control information. Because the RE numbered 0 is occupied by the PT-RS, the REs to which the control information is mapped can start to be mapped from the REs numbered 1, and the numbers of the MCS control information mapped on the symbol 4 of the PDSCH are 1, 5, 9, 13, 17, 21, 25, 29 on RE.
需要说明的是,当按照上述方式对控制信息进行映射时,映射的RE可能与PT-RS所占用的RE重合,此时控制信息映射的RE可以跳过该RE。例如,在上述编号为0的RE上,控制信息与PT-RS重合,因此在映射时,控制信息可以从编号为1的RE开始映射,此时控制信息映射的RE可以整体向后偏移1个RE,控制信息映射在图8中第一物理共享信道的符号4上的编号为1、5、9、13、17、21、25、29的RE上;或者,与PT-RS重合的控制信息可以推迟1个RE进行映射,而不影响控制信息其他RE的映射位置。示例性地,如图8所示,控制信息可以从编号为1的RE开始映射,此时控制信息映射的未与PT-RS所占用的RE重合的RE位置不变,如,控制信息映射在第一物理共享信道的符号4上的编号为1、4、8、12、16、20、25(因为编号24上有PT-RS,故向后偏移1个RE)、28的RE上。It should be noted that when the control information is mapped in the above manner, the mapped RE may overlap with the RE occupied by the PT-RS, and at this time the RE mapped by the control information may skip the RE. For example, on the above-mentioned RE numbered 0, the control information overlaps with the PT-RS. Therefore, during mapping, the control information can be mapped from the RE numbered 1. At this time, the RE mapped to the control information can be shifted backward by 1 as a whole. RE, the control information is mapped on the REs numbered 1, 5, 9, 13, 17, 21, 25, and 29 on the symbol 4 of the first physical shared channel in Figure 8; or, the control overlapped with the PT-RS Information can be deferred to be mapped by one RE, without affecting the mapping positions of other REs of control information. Exemplarily, as shown in FIG. 8, the control information can be mapped from the RE numbered 1. At this time, the position of the RE mapped by the control information that does not overlap with the RE occupied by the PT-RS remains unchanged. For example, the control information is mapped in The numbers on symbol 4 of the first physical shared channel are 1, 4, 8, 12, 16, 20, 25 (because there is a PT-RS on number 24, so it is shifted backward by 1 RE), and 28 REs.
此外,当控制信息所需的RE数量超过该符号上的第一RE数量时,根据上述规则,将控制信息映射至下一个符号上,例如符号5。In addition, when the number of REs required by the control information exceeds the first number of REs on the symbol, the control information is mapped to the next symbol, such as symbol 5, according to the above rule.
情形5 Scenario 5
在当前NR标准中,一个SPS每次只能调度一个物理共享信道传输SPS数据(也可称为时隙或者传输块TB,即一个物理共享信道也可以表示为一个时隙或者一个TB,为便于描述,本申请统一采用物理共享信道来进行介绍),但由于一个XR视频帧尺寸较大,因此通常需要同时调度多个SPS才能够传输一个XR视频帧。基于此,在本申请实施例中, 考虑将控制信息应用于信息传输的多个SPS中。In the current NR standard, an SPS can only schedule one physical shared channel to transmit SPS data at a time (also called a time slot or a transmission block TB, that is, a physical shared channel can also be expressed as a time slot or a TB, for convenience description, this application uniformly adopts the physical shared channel for introduction), but because the size of one XR video frame is relatively large, it is usually necessary to schedule multiple SPSs at the same time to be able to transmit one XR video frame. Based on this, in the embodiment of the present application, it is considered to apply the control information to multiple SPSs for information transmission.
在本申请实施例中,可以将多个SPS设置关联关系,例如,在带宽部分(bandwidth part,BWP)下行链路专用信息BWP-DownlinkDedicatedinformation element中加入SPS配置添加修改列表指示标志sps-configToAddModListFlag,用于指示SPS配置添加修改列表sps-configToAddModList中的SPS关联关系。例如,当SPS配置添加修改列表指示标志sps-configToAddModListFlag取第一值时,如‘1’时,该SPS配置添加修改列表sps-configToAddModList中的多个SPS进程存在关联性,否则当SPS配置添加修改列表指示标志sps-configToAddModListFlag取第二值时,如‘0’时,不存在关联性。若该SPS配置添加修改列表sps-configToAddModList中的SPS存在关联性,则该SPS配置添加修改列表sps-configToAddModList中任意SPS的第一物理共享信道中的控制信息对该SPS配置添加修改列表sps-configToAddModList中的所有相关SPS所传输的数据生效。示例性地,SPS配置添加修改列表指示标志sps-configToAddModListFlag(加粗斜体)在BWP配置的部分字段可以如下所示:In the embodiment of the present application, a plurality of SPSs can be set to have an association relationship, for example, in the bandwidth part (bandwidth part, BWP) downlink dedicated information BWP-DownlinkDedicatedinformation element, add the SPS configuration addition modification list indicator sps-configToAddModListFlag, use It is used to instruct the SPS configuration to add the SPS relationship in the modification list sps-configToAddModList. For example, when the SPS configuration addition modification list indication flag sps-configToAddModListFlag takes the first value, such as '1', the SPS configuration addition modification list sps-configToAddModList is associated with multiple SPS processes, otherwise when the SPS configuration addition modification When the list indication flag sps-configToAddModListFlag takes the second value, such as '0', there is no association. If the SPS configuration addition modification list sps-configToAddModList is related to the SPS, then the SPS configuration addition modification list sps-configToAddModList adds the control information in the first physical shared channel of any SPS to the SPS configuration addition modification list sps-configToAddModList The data transmitted by all relevant SPS in the . Exemplarily, the SPS configuration adding modification list indication flag sps-configToAddModListFlag (bold and italic) in some fields of the BWP configuration may be as follows:
具体地,第一配置信息包括上述带宽部分下行链路专用信息BWP-DownlinkDedicatedinformation element,本申请可以在字段中增加字段sps-configToAddModListFlag-r18(加粗斜体),用于指示SPS配置添加修改列表sps-configToAddModList中的SPS关联关系。第一配置信息中的其他参数可以参考当前第三代合作伙伴计划(3
rd partnership project,3GPP)标准中技术规范(technical specification,TS)38.331协议。发送端设备(即第二通信装置)将该第一配置信息发送接收端设备(即第一通信装置),接收端设备可以根据该第一配置信息中的sps-configToAddModListFlag参数确定该SPS配置添加修改列表sps-configToAddModList中的SPS存在关联性,通过将列表中的多个SPS设置关联关系,可以将控制信息同时应用于列表中的多个SPS,有助于节省信令开销,减少设备能耗。
Specifically, the first configuration information includes the above bandwidth part downlink dedicated information BWP-DownlinkDedicatedinformation element, and the present application may add a field sps-configToAddModListFlag-r18 (bold and italic) in the field to indicate that the SPS configuration adds a modification list sps- SPS association in configToAddModList. For other parameters in the first configuration information, reference may be made to the technical specification (technical specification, TS) 38.331 protocol in the current 3rd Generation Partnership Project (3rd Partnership Project, 3GPP) standard. The sending end device (that is, the second communication device) sends the first configuration information to the receiving end device (that is, the first communication device), and the receiving end device can determine the SPS configuration addition modification according to the sps-configToAddModListFlag parameter in the first configuration information The SPSs in the list sps-configToAddModList are related. By setting the relationship between multiple SPSs in the list, the control information can be applied to multiple SPSs in the list at the same time, which helps to save signaling overhead and reduce equipment energy consumption.
如图9所示,在时分双工中时隙配比每10个时隙包含为8个下行时隙(downlink,DL)和2个上行时隙(uplink,UL)下,子载波间隔(subcarrier spacing,SCS)为15kHz时,假设RRC配置4个SPS来传输XR视频业务,且每个SPS的传输周期都为10ms。此时,可以将该4个SPS设置关联关系。例如,设置SPS配置添加修改列表指示标志sps-configToAddModListFlag取第一值时,即该4个SPS存在关联性,此时可以在该SPS配置添加修改列表sps-configToAddModList中指示标识sps-config Index最低的SPS进程中传输第一物理共享信道。示例性地,若SPS配置添加修改列表sps-configToAddModList中包含4个SPS,分别为对应SPS-config Index0-3(简称SPS 0-3),如图9所示(该图例不包括PT-RS信号),指示标识sps-config Index最低的SPS用于传输第一物理共享信道,即SPS0所对应的物理共享信道上,且第一物理共享信道的该控制信息对该SPS配置添加修改列表sps-configToAddModList中的所有SPS,即SPS0-3,所传输的物理共享信道有效。应理解,SPS配置添加修改列表指示标志sps-configToAddModListFlag取第一值时,也可以指示其他sps-config Index的SPS用于传输第一物理共享信道,本申请对此不做限制。As shown in Figure 9, in time division duplexing, the time slot ratio of every 10 time slots includes 8 downlink time slots (downlink, DL) and 2 uplink time slots (uplink, UL), the subcarrier spacing (subcarrier When spacing, SCS) is 15kHz, it is assumed that RRC configures 4 SPSs to transmit XR video services, and the transmission period of each SPS is 10ms. At this point, the four SPSs may be set in an association relationship. For example, when the SPS configuration add modification list indication flag sps-configToAddModListFlag is set to take the first value, that is, the four SPSs are related, at this time, the SPS configuration addition modification list sps-configToAddModList can be indicated in the sps-configToAddModList with the lowest value The first physical shared channel is transmitted in the SPS process. Exemplarily, if the SPS configuration addition modification list sps-configToAddModList contains 4 SPSs, which are corresponding to SPS-config Index0-3 (SPS 0-3 for short), as shown in Figure 9 (the legend does not include PT-RS signals ), indicating that the SPS with the lowest sps-config Index is used to transmit the first physical shared channel, that is, the physical shared channel corresponding to SPS0, and the control information of the first physical shared channel adds a modification list sps-configToAddModList to the SPS configuration All SPSs in , that is, SPS0-3, the physical shared channel transmitted is valid. It should be understood that when the SPS configuration addition modification list indication flag sps-configToAddModListFlag takes the first value, it may also indicate that SPSs of other sps-config Indexes are used to transmit the first physical shared channel, which is not limited in this application.
情形6 Scenario 6
该情形下考虑将控制信息应用于信息传输的1个SPS的N个物理共享信道的场景。In this situation, a scenario in which control information is applied to N physical shared channels of one SPS for information transmission is considered.
在本申请实施例中,可以在第一配置信息中增加指示信息,用于指示控制信息应用的物理共享信道的个数。其中,这些物理共享信道可以是相邻的物理共享信道,也可以是不相邻的物理共享信道。一种可能的方式为,在SPS配置SPS-config信令中加入时隙个数nrofSlot指示符,其取值可以为2-8等,用于指示SPS调度的物理共享信道的个数。此时,nrofSlot指示符(加粗斜体)在SPS配置的部分字段可以如下所示:In this embodiment of the present application, indication information may be added to the first configuration information, which is used to indicate the number of physical shared channels to which the control information applies. Wherein, these physical shared channels may be adjacent physical shared channels, or may be non-adjacent physical shared channels. One possible manner is to add an nrofSlot indicator of the number of timeslots in the SPS-config signaling of the SPS configuration, and its value can be 2-8, etc., which is used to indicate the number of physical shared channels scheduled by the SPS. At this time, the nrofSlot indicator (bold and italic) can be shown as follows in some fields of SPS configuration:
具体地,第一配置信息包括或本身即为上述SPS配置SPS-config信令,本申请可以在字段中增加物理共享信道数量指示信息字段nrofSlot,用于指示SPS调度的物理共享信道的个数,即每次SPS传输机会所传输的物理共享信道的个数。第一配置信息中的其他参数可以参考当前3GPP标准中TS38.331协议。发送端设备(即第二通信装置)将该第一配置信息发送接收端设备(即第一通信装置),接收端设备可以根据该第一配置信息中的nrofSlot参数确定该控制信息可以应用的物理共享信道的个数,通过此方法,接收端设备可以知道每个SPS传输机会所要接收的物理共享信道的个数,有助于提升传输的灵活性。Specifically, the first configuration information includes or itself configures the SPS-config signaling for the above-mentioned SPS, and the present application may add a physical shared channel number indication information field nrofSlot in the field, which is used to indicate the number of physical shared channels scheduled by the SPS, That is, the number of physical shared channels transmitted by each SPS transmission opportunity. For other parameters in the first configuration information, reference may be made to the TS38.331 protocol in the current 3GPP standard. The sending end device (that is, the second communication device) sends the first configuration information to the receiving end device (that is, the first communication device), and the receiving end device can determine the physical location where the control information can be applied according to the nrofSlot parameter in the first configuration information. The number of shared channels, through this method, the receiving end device can know the number of physical shared channels to be received by each SPS transmission opportunity, which helps to improve the flexibility of transmission.
示例性的,如图10(该图例不包括PT-RS信号)所示,假设在nrofSlot=4的情况下,起始于D05的SPS传输本应于D05-U00传输数据,但U00为上行数据,所以不相邻时隙为D05-D07和D10。或者,假设在nrofSlot=4的情况下,如图10(该图例不包括PT-RS信号)所示,起始于D05的SPS传输本应于D05-U00传输数据,但由于U00用于承载上行数据,所以SPS传输时隙为D05-D07,即由于SPS传输时隙与上行时隙冲突,SPS传输本应在U00传输的时隙不再用于SPS数据传输,且SPS不再推迟或补偿该SPS传输时隙。Exemplarily, as shown in Figure 10 (the legend does not include PT-RS signals), suppose that in the case of nrofSlot=4, the SPS transmission starting at D05 should have transmitted data at D05-U00, but U00 is uplink data , so the non-adjacent time slots are D05-D07 and D10. Or, suppose that in the case of nrofSlot=4, as shown in Figure 10 (the legend does not include PT-RS signals), the SPS transmission starting from D05 should have transmitted data at D05-U00, but because U00 is used to carry uplink data, so the SPS transmission time slot is D05-D07, that is, due to the conflict between the SPS transmission time slot and the uplink time slot, the time slot that SPS transmission should have been transmitted in U00 is no longer used for SPS data transmission, and SPS will no longer delay or compensate for this SPS transmission time slot.
可选地,可以将控制信息加入到用PDSCH携带的信令中,例如,在RRC信令中的sps-config中加入独立控制selfContainedControlIE信令,该信令为空时,本实施例所示的映射方法不开启。又或者,独立控制selfContainedControlIE信令内可以包含一或多个配置信息,如MCS,nrofTB等配置信息。此时,独立控制selfContainedControlIE信令(加粗斜体)在SPS配置的部分字段可以如下所示:Optionally, the control information can be added to the signaling carried by the PDSCH, for example, the independent control selfContainedControlIE signaling is added to the sps-config in the RRC signaling. When the signaling is empty, the The mapping method is not turned on. Alternatively, the independent control selfContainedControlIE signaling may include one or more configuration information, such as MCS, nrofTB and other configuration information. At this time, the independent control selfContainedControlIE signaling (bold and italic) can be configured in some fields of the SPS as follows:
具体地,第一配置信息包括或本身即为上述SPS配置SPS-config信令,本申请可以在字段中增加字段selfContainedControlIE,用于指示对应的SPS中包含第一物理共享信道。更进一步的,可以通过增加字段MCS来指示该第一物理共享信道中的控制信息是否包含的第一调制方式和/或第一编码方式,以及增加字段nrofTB,用于指示第一物理共享信道中的控制信息是否包含物理共享信道数量指示信息。需要注意的是,此时nrofTB字段的大小为发送端和接收端设备已知的预配置参量。通过第一物理信道中的控制信息中的nrofTB内容,发送端设备可以灵活指示每次SPS传输机会所传输的物理共享信道的个数。需要注意的是,该物理共享信道的个数可以包括第一物理共享信道。发送端设备(即第二通信装置)将该第一配置信息发送接收端设备(即第一通信装置),接收端设备可以根据该第一配置信息中的selfContainedControlIE参数确定第一物理共享信道中的控制信息的内容,并根据该控制信息中的MCS参数确定SPS传输的物理共享信道中数据的第一调制方式和/或第一编码方式,以及根据控制信息中的nrofTB参数确定每次SPS传输机会所传输的物理共享信道的个数。第一配置信息中的其他参数可以参考当前3GPP标准中TS38.331协议。通过此方法,可以让接收端设备准确、高效的识别该方法的生效与否。将控制信息承载于第一配置信息中,有助于减少通信时延,节省信令开销。Specifically, the first configuration information includes or itself configures the SPS-config signaling for the above-mentioned SPS, and the present application may add a field selfContainedControlIE to indicate that the corresponding SPS contains the first physical shared channel. Furthermore, the field MCS can be added to indicate whether the control information in the first physical shared channel contains the first modulation scheme and/or the first coding scheme, and the field nrofTB can be added to indicate that the control information in the first physical shared channel Whether the control information of the control information includes the indication information of the number of physical shared channels. It should be noted that at this time, the size of the nrofTB field is a pre-configured parameter known by the sending end and the receiving end device. Through the nrofTB content in the control information in the first physical channel, the sending end device can flexibly indicate the number of physical shared channels to be transmitted for each SPS transmission opportunity. It should be noted that the number of physical shared channels may include the first physical shared channel. The sending end device (that is, the second communication device) sends the first configuration information to the receiving end device (that is, the first communication device), and the receiving end device can determine the configuration information in the first physical shared channel according to the selfContainedControlIE parameter in the first configuration information. The content of the control information, and according to the MCS parameter in the control information, determine the first modulation method and/or the first coding method of the data in the physical shared channel of SPS transmission, and determine each SPS transmission opportunity according to the nrofTB parameter in the control information The number of physical shared channels transmitted. For other parameters in the first configuration information, reference may be made to the TS38.331 protocol in the current 3GPP standard. Through this method, the receiving end device can accurately and efficiently identify whether the method is valid or not. Carrying the control information in the first configuration information helps to reduce communication delay and save signaling overhead.
示例性地,selfContainedControlIE指示了MCS和nrofTB两个参数。本申请对该selfContainedControlIE所指示的具体内容不做限制。Exemplarily, selfContainedControlIE indicates two parameters of MCS and nrofTB. This application does not limit the specific content indicated by the selfContainedControlIE.
示例性地,可以将该指示信息复用至每次SPS传输的第一个物理共享信道中,用于指示该控制信息将对该次或接下来的多次的SPS数据生效。Exemplarily, the indication information may be multiplexed into the first physical shared channel of each SPS transmission, and used to indicate that the control information will take effect on this or the next multiple SPS data.
具体地,通过在第一配置信息中加入nrofTBs信令,一个SPS每次可以传输多个物理共享信道。如当nrofTBs=n4时,即N=4,一个SPS每次可以传输4个物理共享信道。图10(该图例不包括PT-RS信号)展示了在SCS为15kHz下,SPS传输周期为10ms时,一个SPS传输4个物理共享信道的场景,其中D00-D03为一次SPS传输机会,D10-D13为相邻的下一次SPS传输机会。其中,每次传输机会包含1个第一物理共享信道和3个物理共享信道。示例性地,为了降低解码时延,可以采用每次SPS传输的第一个TB承载该第一物理共享信道,该第一物理共享信道中的控制信息将对该次的SPS数据生效,即D00的第一物理共享信道中的控制信息,如MCS,可用于解码D00-D03中的SPS数据。D00、D01、D02和D03上的数据生效。Specifically, by adding nrofTBs signaling to the first configuration information, one SPS can transmit multiple physical shared channels each time. For example, when nrofTBs=n4, that is, N=4, one SPS can transmit 4 physical shared channels each time. Figure 10 (the illustration does not include PT-RS signals) shows a scenario where one SPS transmits four physical shared channels when the SCS is 15kHz and the SPS transmission period is 10ms, where D00-D03 is an SPS transmission opportunity, and D10- D13 is an adjacent next SPS transmission opportunity. Wherein, each transmission opportunity includes one first physical shared channel and three physical shared channels. Exemplarily, in order to reduce the decoding delay, the first TB of each SPS transmission can be used to carry the first physical shared channel, and the control information in the first physical shared channel will take effect for the SPS data of this time, that is, D00 The control information in the first physical shared channel, such as MCS, can be used to decode the SPS data in D00-D03. The data on D00, D01, D02 and D03 take effect.
应理解,在实际应用中,上述情形5和情形6可以同时存在,这样可以进一步减小开销,节省能耗。It should be understood that in practical applications, the foregoing situation 5 and situation 6 may exist simultaneously, which can further reduce overhead and save energy consumption.
例如,控制信息可以应用于多个SPS的多个物理共享信道中,此时多个物理共享信道可以是相邻的物理共享信道,如图11中所示(该图例不包括PT-RS信号),SPS配置添加修改列表sps-configToAddModList中包含SPS0和SPS1,且SPS0和SPS1配置中的nrofTBs=n2。D00和D01为SPS0一次传输机会的数据,D10和D11为SPS0下一相邻传输机会的数据,D02和D03为SPS1一次传输机会的数据,D12和D13为SPS1下一相邻传输机会的数据。示例性地,在该SPS配置添加修改列表sps-configToAddModList中指示标识sps-config Index最低的SPS进程中承载一个第一物理共享信道,如D00。其中,D00中的第一物理共享信道所携带的控制信息对SPS0的D00-D01及SPS1的D02-D03生效,D10所携带的控制信息对SPS0的D10-D11及SPS1的D12-D13生效。应理解,SPS配置添加修改列表指示标志sps-configToAddModListFlag取第一值时,也可以指示其他sps-config Index的SPS用于传输第一物理共享信道,本申请对此不做限制。For example, the control information can be applied to multiple physical shared channels of multiple SPSs. At this time, the multiple physical shared channels can be adjacent physical shared channels, as shown in FIG. 11 (the illustration does not include PT-RS signals) , the SPS configuration addition modification list sps-configToAddModList includes SPS0 and SPS1, and nrofTBs=n2 in the configurations of SPS0 and SPS1. D00 and D01 are the data of one transmission opportunity of SPS0, D10 and D11 are the data of the next adjacent transmission opportunity of SPS0, D02 and D03 are the data of one transmission opportunity of SPS1, and D12 and D13 are the data of the next adjacent transmission opportunity of SPS1. Exemplarily, the SPS process indicated in the SPS configuration addition modification list sps-configToAddModList with the lowest sps-config Index bears a first physical shared channel, such as D00. Wherein, the control information carried by the first physical shared channel in D00 takes effect on D00-D01 of SPS0 and D02-D03 of SPS1, and the control information carried by D10 takes effect on D10-D11 of SPS0 and D12-D13 of SPS1. It should be understood that when the SPS configuration addition modification list indication flag sps-configToAddModListFlag takes the first value, it may also indicate that SPSs of other sps-config Indexes are used to transmit the first physical shared channel, which is not limited in this application.
需要注意的是,情形1-6中的第一物理共享信道的周期和一个或多个SPS的周期时相同的。也就是说,每次一个或多个SPS传输都会携带一个第一物理共享信道,且该第一物理共享信道的控制信息,如MCS,可以用于一个或多个每次SPS传输机会。It should be noted that the period of the first physical shared channel in scenarios 1-6 is the same as the period of one or more SPSs. That is, each transmission of one or more SPSs carries a first physical shared channel, and the control information of the first physical shared channel, such as MCS, can be used for each of one or more SPS transmission opportunities.
例如,控制信息还可以应用于一个或多个SPS的M个物理共享信道,此时M个物理共享信道可以是不相邻的物理共享信道,例如,M个物理共享信道为该SPS一个或多个传输周期的N个物理共享信道的整数倍,即M为N的整数倍,此时控制信息应用于一个或多个SPS的M/N个传输周期。如图10所示,一个SPS传输N=4个物理共享信道,其中,D00至D03为SPS0一个传输机会的数据,D10至D13为SPS0下一个相邻传输机会的数据。当M=8,假设第一物理共享信道位于D00时刻上,该第一物理共享信道所携带的控制信息可以对SPS0传输周期的D00至D03以及SPS0下一相邻传输周期的D10至D13生效。具体地,一种实现方式为在第一配置信息中携带周期参数(例如,SPS-config中的sps-selfContainedControlIEPeriod),例如周期参数为2,即表示控制信息对包括本次传输在内的两个传输周期的信息传输生效;另一种可能的实现方式为在第一配置信息中配置生效次数,比如生效次数2,即表示每2个SPS传输机会出现一次第一物理共享信道的控制信息。此时,周期参数sps-selfContainedControlIEPeriod(加粗斜体)在SPS配置的部分字段可以如下所示:For example, the control information can also be applied to M physical shared channels of one or more SPSs. At this time, the M physical shared channels can be non-adjacent physical shared channels. For example, the M physical shared channels are one or more physical shared channels of the SPS. Integer multiples of N physical shared channels in one transmission cycle, that is, M is an integer multiple of N, at this time the control information is applied to M/N transmission cycles of one or more SPSs. As shown in FIG. 10 , one SPS transmits N=4 physical shared channels, wherein D00 to D03 are the data of one transmission opportunity of SPS0, and D10 to D13 are the data of the next adjacent transmission opportunity of SPS0. When M=8, assuming that the first physical shared channel is located at time D00, the control information carried by the first physical shared channel can take effect for D00 to D03 of the SPSO transmission period and D10 to D13 of the next adjacent transmission period of SPSO. Specifically, one implementation is to carry a period parameter (for example, sps-selfContainedControlIEPeriod in SPS-config) in the first configuration information. For example, the period parameter is 2, which means that the control information is valid for two transmissions including this transmission. The information transmission of the transmission cycle takes effect; another possible implementation is to configure the number of times of validity in the first configuration information, for example, the number of times of validity is 2, which means that the control information of the first physical shared channel appears once every 2 SPS transmission opportunities. At this time, the period parameter sps-selfContainedControlIEPeriod (bold and italic) can be shown as follows in some fields of SPS configuration:
具体地,第一配置信息包括或本身即为上述SPS配置SPS-config信令,本申请可以在字段中增加字段sps-selfContainedControlIEPeriod,用于指示控制信息生效的传输周期的个数,也可以理解为第一物理共享信道出现的周期间隔。第一配置信息中的其他参数可以参考当前3GPP标准中TS38.331协议。发送端设备(即第二通信装置)将该第一配置信息发送接收端设备(即第一通信装置),接收端设备可以根据该第一配置信息中的sps-selfContainedControlIEPeriod参数确定该控制信息生效的传输周期个数,即该控制信息对接下来的几个传输周期的物理共享信道生效。通过此方法,可以让接收端设备识别该控制信息生效的传输周期个数,进一步地,将控制信息以及控制信息应用的传输周期的个数信息同时承载于第一配置信息中,有助于提升传输灵活性。Specifically, the first configuration information includes or itself configures SPS-config signaling for the above-mentioned SPS. The present application may add a field sps-selfContainedControlIEPeriod to the field to indicate the number of transmission periods for which the control information takes effect, which can also be understood as Periodic interval at which the first physical shared channel occurs. For other parameters in the first configuration information, reference may be made to the TS38.331 protocol in the current 3GPP standard. The sending end device (that is, the second communication device) sends the first configuration information to the receiving end device (that is, the first communication device), and the receiving end device can determine the period when the control information takes effect according to the sps-selfContainedControlIEPeriod parameter in the first configuration information. The number of transmission cycles, that is, the control information takes effect on the physical shared channel of the next several transmission cycles. Through this method, the receiver device can identify the number of transmission cycles for which the control information takes effect. Further, the control information and the number of transmission cycles for which the control information is applied are carried in the first configuration information at the same time, which helps to improve Transport flexibility.
示例性地,sps-selfContainedControlIEPeriod指示了n1到n4四个参数,本申请不限制该sps-selfContainedControlIEPeriod所指示参数的数值和数量。或者,该sps-selfContainedControlIEPeriod也可以放入独立控制selfContainedControlIE信令中,如下所示:Exemplarily, sps-selfContainedControlIEPeriod indicates four parameters n1 to n4, and the present application does not limit the value and number of parameters indicated by sps-selfContainedControlIEPeriod. Alternatively, the sps-selfContainedControlIEPeriod can also be put into the independent control selfContainedControlIE signaling, as follows:
S450,第一通信装置接收来自第二通信装置的控制信息和数据,该控制信息和数据复用在第一物理共享信道上,该控制信息用于指示数据的第一调制方式和/或第一编码方式。S450. The first communication device receives control information and data from the second communication device, the control information and data are multiplexed on the first physical shared channel, and the control information is used to indicate the first modulation mode of the data and/or the first Encoding.
本申请对于控制信息和数据的映射的先后顺序不作限定,例如,可以先将控制信息进行映射,后对数据进行映射,此时数据映射在第一物理共享信道的第二RE上,第二RE为第一物理共享信道中未承载控制信息、DM-RS和PT-RS的资源单元。又例如,可以先完成对数据的映射,再进行控制信息的映射,即采用“打孔”的方式,将控制信息映射到物理共享信道的资源上,此时可能控制信息会替换掉部分数据。具体地,先采用速率匹配的方式将SPS数据按照先频域后时域的顺序映射至该第一物理共享信道的第二RE上,第二RE为第一物理共享信道中未承载控制信息、DM-RS和PT-RS的资源单元。需要注意的是,第二RE同样需要考虑CDM组和天线端口号的影响。之后将控制信息映射到该物理信道的第一RE上,由于此时第一RE包括第二RE,即第一RE和第二RE对应相同符号中的相同RE编号,所以控制信息映射在第一RE的过程中,可能会替换掉映射在相同RE上的数据。例如,上述图5也可以理解为,SPS数据从第一物理共享信道中的符号2开始按照先频域后时域的顺序映射至PDSCH的多个符号上,在SPS数据映射结束后,确定承载控制信息的第一符号为符号3,且第一频域映射间隔为d=floor(36/16)=2,即在符号3上,每隔2个RE映射一个控制信息所需的RE,则最终的结果是,控制信息映射在第一物理共享信道的符号3上的RE编号为0、2、6、8、10、12、14、16、18、20、22、24、28、30的RE上,并替换掉这些RE上的数据。This application does not limit the sequence of mapping control information and data. For example, the control information can be mapped first, and then the data can be mapped. At this time, the data is mapped to the second RE of the first physical shared channel, and the second RE It is a resource unit not carrying control information, DM-RS and PT-RS in the first physical shared channel. For another example, the mapping of data can be completed first, and then the mapping of control information can be performed, that is, the control information can be mapped to the resources of the physical shared channel in a "punching" manner. At this time, the control information may replace part of the data. Specifically, the rate matching method is first used to map the SPS data to the second RE of the first physical shared channel in the order of the frequency domain first and then the time domain. The second RE is that the first physical shared channel does not carry control information, Resource elements of DM-RS and PT-RS. It should be noted that the second RE also needs to consider the influence of the CDM group and the antenna port number. Then map the control information to the first RE of the physical channel. Since the first RE includes the second RE at this time, that is, the first RE and the second RE correspond to the same RE number in the same symbol, so the control information is mapped on the first RE. In the process of RE, the data mapped on the same RE may be replaced. For example, the above-mentioned Figure 5 can also be understood as that the SPS data starts from symbol 2 in the first physical shared channel and is mapped to multiple symbols of the PDSCH in the order of the frequency domain and then the time domain. After the SPS data mapping is completed, the bearer The first symbol of the control information is symbol 3, and the first frequency-domain mapping interval is d=floor(36/16)=2, that is, on symbol 3, every 2 REs are mapped to an RE required for the control information, then The final result is that the control information is mapped to the RE numbers 0, 2, 6, 8, 10, 12, 14, 16, 18, 20, 22, 24, 28, 30 on the symbol 3 of the first physical shared channel RE, and replace the data on these REs.
在本申请中,“指示”可以显式地和/或隐式地指示。示例性地,隐式指示可以基于用于传输的位置和/或资源;显式指示可以基于一个或多个参数,和/或一个或多个索引, 和/或一个或多个它所表示的位模式。此外,“指示”还可以表示“包含”,例如,控制信息指示半静态传输的调制方式和/或编码方式的信息,也可以表述为:控制信息包含半静态传输的调制方式和/或编码方式的信息。In this application, "indicate" may indicate explicitly and/or implicitly. Exemplarily, an implicit indication may be based on the location and/or resources used for transmission; an explicit indication may be based on one or more parameters, and/or one or more indices, and/or one or more bit pattern. In addition, "indicate" may also mean "include", for example, the information indicating the modulation mode and/or coding mode of semi-static transmission in the control information may also be expressed as: the control information includes the modulation mode and/or coding mode of semi-static transmission Information.
S460,第一通信装置接收来自第二通信装置的第一配置信息,第一配置信息用于配置半静态传输,承载半静态传输的物理共享信道包括第一物理共享信道。S460. The first communication device receives first configuration information from the second communication device, where the first configuration information is used to configure semi-static transmission, and the physical shared channel carrying the semi-static transmission includes the first physical shared channel.
其中,第一配置信息还用于配置半静态传输的N个物理共享信道,该N个物理共享信道包括第一物理共享信道。例如,该N个物理共享信道可以对应与上述一个SPS的物理共享信道,即控制信息的周期与SPS周期相同。Wherein, the first configuration information is also used to configure N physical shared channels for semi-static transmission, and the N physical shared channels include the first physical shared channel. For example, the N physical shared channels may correspond to the physical shared channel of the above-mentioned one SPS, that is, the cycle of the control information is the same as the cycle of the SPS.
在另一种实现方式中,控制信息的周期与SPS周期不同,例如,第一配置信息还用于指示控制信息应用于半静态传输的数据对应的M个物理共享信道,M为N的正整数倍,即控制信息应用于SPS的多个周期。例如,如图11所示,一个SPS的传输周期为10ms,且包含N=4个物理共享信道。其中,D00处包含第一物理共享信道,该第一物理共享信道的控制信息对M=8个物理共享信道生效,或者说,该控制信息的传输周期为SPS传输周期的两倍,即20ms。该M个物理共享信道可以对应于一个SPS的两个传输周期的物理共享信道。其中,该M个物理共享信道的数据是根据控制信息的第一调制和/或第一编码方式处理的。In another implementation, the period of the control information is different from the period of the SPS. For example, the first configuration information is also used to indicate that the control information is applied to the M physical shared channels corresponding to the semi-statically transmitted data, and M is a positive integer of N. times, that is, the control information is applied to the number of cycles of the SPS. For example, as shown in FIG. 11 , the transmission period of one SPS is 10 ms, and includes N=4 physical shared channels. Wherein, D00 contains the first physical shared channel, and the control information of the first physical shared channel takes effect for M=8 physical shared channels, or in other words, the transmission period of the control information is twice the SPS transmission period, that is, 20ms. The M physical shared channels may correspond to the physical shared channels of two transmission periods of one SPS. Wherein, the data of the M physical shared channels is processed according to the first modulation and/or first coding manner of the control information.
可选地,第一配置信息还用于指示控制信息映射至第一物理共享信道的符号的符号排序信息。例如,该符号排序信息对应于上述情形3中的符号顺序。其中,该符号排序信息根据临近一个或多个DM-RS的方式排序或者顺序排序。Optionally, the first configuration information is further used to indicate symbol ordering information of symbols that control information is mapped to the first physical shared channel. For example, the symbol ordering information corresponds to the symbol order in Case 3 above. Wherein, the symbol sorting information is sorted according to the manner or sequence of one or more DM-RSs adjacent to each other.
可选地,第一配置信息还用于指示控制信息应用于半静态传输的一个或多个TB,例如,对应于上述情形6所述的可以在第一配置信息中增加指示信息,用于指示控制信息应用的TB的个数。其中,这些传输块可以是相邻的传输块,也可以是不相邻的传输块。Optionally, the first configuration information is also used to indicate that the control information is applied to one or more TBs for semi-static transmission. The number of terabytes used to control information. Wherein, these transport blocks may be adjacent transport blocks or non-adjacent transport blocks.
其中,第一配置信息还用于指示控制信息的第二调制方式和/或第二编码方式。这样,第一通信装置可以根据控制信息的第二调制方式和/或第二编码方式对控制信息进行解码,获得控制信息。Wherein, the first configuration information is also used to indicate the second modulation mode and/or the second coding mode of the control information. In this way, the first communication device may decode the control information according to the second modulation mode and/or the second coding mode of the control information to obtain the control information.
S470,第一通信装置根据第一调制和/或第一编码方式,对数据进行解码。S470. The first communication device decodes the data according to the first modulation and/or the first coding mode.
根据本申请的技术方案,通过将数据和数据对应的控制信息复用在同一个物理共享信道中,有助于在降低检测控制信息检测开销的同时,提供数据的可靠传输。According to the technical solution of the present application, by multiplexing the data and the control information corresponding to the data in the same physical shared channel, it is helpful to provide reliable transmission of data while reducing the detection overhead of detection control information.
需要说明的是,上述方案以SPS场景为例对本申请的方案进行了介绍,但其不应对本申请的应用场景产生任何限定。It should be noted that the above solution introduces the solution of the present application by taking the SPS scenario as an example, but it should not limit the application scenario of the present application in any way.
例如,本申请的技术方案同样可以应用于动态调度场景的初传和重传场景,以下行场景为例,可以在PDSCH配置PDSCH-CONFIG中加入第一配置信息,(如,独立控制selfContainedControlIE信令),该第一配置信息还可以包括多个配置信息,如MCS,HARQ进程标识ID等配置信息。若该第一配置信息被配置,则控制信息可以按照上述方法映射至DCI所对应的第一物理共享信道PDSCH资源中,接收端译码DCI时忽略DCI中所包含的控制信息,或者DCI中不包含第一配置信息所包含的配置信息,而是从PDSCH中获得控制信息。具体地,将MCS和HARQ进程ID等信息按照规定顺序(如先MCS后HARQ ID)级联后,附加CRC码和信道编码,然后按照上述方法映射至PDSCH资源上。此时,独立控制selfContainedControlI信令(加粗斜体)在PDSCH配置的部分字段可以如下所示:For example, the technical solution of the present application can also be applied to the initial transmission and retransmission scenarios of the dynamic scheduling scenario. Take the downlink scenario as an example, the first configuration information can be added to the PDSCH configuration PDSCH-CONFIG (for example, independently control the selfContainedControlIE signaling ), the first configuration information may also include a plurality of configuration information, such as MCS, HARQ process identification ID and other configuration information. If the first configuration information is configured, the control information can be mapped to the first physical shared channel PDSCH resource corresponding to the DCI according to the above method, and the receiving end ignores the control information contained in the DCI when decoding the DCI, or the DCI does not include The configuration information included in the first configuration information is included, but the control information is obtained from the PDSCH. Specifically, after concatenating information such as MCS and HARQ process ID in a prescribed order (for example, first MCS and then HARQ ID), add CRC code and channel coding, and then map to PDSCH resources according to the above method. At this time, the independent control selfContainedControlI signaling (bold and italic) can be configured in some fields of the PDSCH as follows:
具体地,第一配置信息包括或本身即为上述SPS配置SPS-config信令,本申请的第一配置信息加入selfContainedControlIE字段,并在该字段中增加字段MCS,用于指示该第一物理共享信道中的控制信息是否包含第一调制方式和/或第一编码方式;还可以增加字段HARQ-ProcessesID,用于指示该第一物理共享信道中的控制信息是否包含HARQ进程信息;还可以增加字段新数据指示符(new data indicator,NDI),用于指示该第一物理共享信道中的控制信息是否包含NDI信息,以及增加字段冗余版本(redundancy versiong,RV),用于指示该第一物理共享信道中的控制信息是否包含RV信息。应理解,上述字段比特大小与3GPP标准中已知,且发送端和接收端设备均已知道上述每个字段的比特大小。以当前3GPP release16为例,MCS字段由5比特构成,HARQ-processID由4比特构成等,信息字段大小可能会随3GPP版本变化而更新。第一配置信息中的其他参数可以参考当前3GPP标准中TS38.331协议。发送端设备(即第二通信装置)将该第一配置信息发送接收端设备(即第一通信装置),接收端设备可以根据该第一配置信息确定第一物理共享信道中的控制信息所包含的内容,从而确定SPS数据的MCS参数、HARQ-ProcessesID参数、NDI参数或RV参数。进一步地,将关于同一个物理共享信道的数据的多个控制信息同时承载于第一配置信息中,有助于减少通信时延,节省信令开销。Specifically, the first configuration information includes or itself configures SPS-config signaling for the above-mentioned SPS. The first configuration information of this application is added to the selfContainedControlIE field, and a field MCS is added to this field to indicate the first physical shared channel Whether the control information in the first physical shared channel contains the first modulation method and/or the first coding method; the field HARQ-ProcessesID can also be added to indicate whether the control information in the first physical shared channel contains HARQ process information; the field new A data indicator (new data indicator, NDI) is used to indicate whether the control information in the first physical shared channel contains NDI information, and a field redundancy version (redundancy versiong, RV) is added to indicate that the first physical shared channel Whether the control information in the channel contains RV information. It should be understood that the bit size of the above field is known in the 3GPP standard, and both the sending end and the receiving end device already know the bit size of each field above. Taking the current 3GPP release16 as an example, the MCS field is composed of 5 bits, and the HARQ-processID is composed of 4 bits. The size of the information field may be updated as the 3GPP version changes. For other parameters in the first configuration information, reference may be made to the TS38.331 protocol in the current 3GPP standard. The sending end device (that is, the second communication device) sends the first configuration information to the receiving end device (that is, the first communication device), and the receiving end device can determine according to the first configuration information that the control information included in the first physical shared channel content, thereby determining the MCS parameter, HARQ-ProcessesID parameter, NDI parameter or RV parameter of the SPS data. Further, carrying multiple pieces of control information about the data of the same physical shared channel in the first configuration information at the same time helps to reduce communication delay and save signaling overhead.
又例如,本申请的技术方案同样可以应用于重传场景,可以在PDSCH-Config中加入第一配置信息,(如,重传独立控制RetransmissionSelfContainedControlIE信令),该第一配置信息可以包含多个配置信息,如MCS,HARQ进程ID等配置信息。若第一配置信息被配置,则控制信令可以按照上述方法映射至DCI所对应的PDSCH资源中,接收端译码DCI时可忽略DCI中所包含的控制信息,而是从PDSCH中获得控制信息。具体地,将MCS和HARQ进程ID等信息按照规定顺序(如先MCS后HARQ ID)级联后,附加CRC码和信道编码,然后按照上述方法映射至PDSCH资源上。或者,当接收端知道重传时刻 的具体位置时,可以选择不解码DCI,而是接收对应时隙的PDSCH数据,并从中解码上述控制信息。For another example, the technical solution of the present application can also be applied to the retransmission scenario, and the first configuration information can be added to the PDSCH-Config (for example, the retransmission independent control RetransmissionSelfContainedControlIE signaling), and the first configuration information can include multiple configurations Information, such as MCS, HARQ process ID and other configuration information. If the first configuration information is configured, the control signaling can be mapped to the PDSCH resource corresponding to the DCI according to the above method, and the receiving end can ignore the control information contained in the DCI when decoding the DCI, but obtain the control information from the PDSCH . Specifically, after concatenating information such as MCS and HARQ process ID in a prescribed order (for example, first MCS and then HARQ ID), add CRC code and channel coding, and then map to PDSCH resources according to the above method. Or, when the receiving end knows the specific location of the retransmission moment, it can choose not to decode the DCI, but to receive the PDSCH data of the corresponding time slot, and decode the above-mentioned control information from it.
此外,本申请的技术方案还可以应用于SPS重传场景,其具体映射方法可以参照上述SPS场景中的介绍。可在SPS-Config(即,第一配置信息)中添加重传独立控制retransmissionSelfContainedControlIE信令,该第一配置信息可以包含多个配置信息,如MCS,HARQ进程ID等配置信息。若第一配置信息被配置,则控制信令可以按照上述方法映射至DCI所对应的PDSCH资源中,接收端译码DCI时可忽略DCI中所包含的控制信息,而是从PDSCH中获得控制信息。具体地,将MCS和HARQ进程ID等信息按照规定顺序(如先MCS后HARQ ID)级联后,附加CRC码和信道编码,然后按照上述方法映射至PDSCH资源上。或者,当接收端知道重传时刻的具体位置时,可以选择不解码DCI,而是接收对应时隙的PDSCH数据,并从中解码上述控制信息。示例性地,重传独立控制retransmissionSelfContainedControlIE信令(加粗斜体)在SPS配置的部分字段可以如下所示:In addition, the technical solution of the present application can also be applied to the SPS retransmission scenario, and the specific mapping method can refer to the introduction in the above SPS scenario. The retransmission independent control retransmissionSelfContainedControlIE signaling can be added to SPS-Config (ie, first configuration information), and the first configuration information can include multiple configuration information, such as MCS, HARQ process ID and other configuration information. If the first configuration information is configured, the control signaling can be mapped to the PDSCH resource corresponding to the DCI according to the above method, and the receiving end can ignore the control information contained in the DCI when decoding the DCI, but obtain the control information from the PDSCH . Specifically, after concatenating information such as MCS and HARQ process ID in a prescribed order (for example, first MCS and then HARQ ID), add CRC code and channel coding, and then map to PDSCH resources according to the above method. Alternatively, when the receiving end knows the specific location of the retransmission moment, it may choose not to decode the DCI, but to receive the PDSCH data of the corresponding time slot, and decode the above-mentioned control information therefrom. Exemplarily, some fields of the SPS configuration in the retransmission self-contained control IE signaling (bold and italic) may be as follows:
具体地,第一配置信息包括或本身即为上述SPS配置SPS-config信令,本申请可以 在字段中增加字段retransmissionSelfContainedControlIE,用于指示该方法可以应用于重传场景。进一步地,可以如上文所述,在retransmissionSelfContainedControlIE中增加MCS参数、HARQ-ProcessesID参数、NDI参数或RV参数,各参数对应的含义请参照上文所述,为了简洁,在此不再赘述。第一配置信息中的其他参数可以参考当前3GPP标准中TS38.331协议。发送端设备(即第二通信装置)将该第一配置信息发送接收端设备(即第一通信装置),接收端设备可以根据该第一配置信息中的retransmissionSelfContainedControlIE参数,将该技术方案应用于重传场景。具体地,在该retransmissionSelfContainedControlIE字段被配置,且接收端设备判断当前接收数据为重传数据后,可以通过解码第一物理共享信道中控制信息的MCS参数、HARQ-ProcessesID参数、NDI参数或RV参数,获取相应参数所指示的信息以便于解码第一物理共享信道中的数据。将关于同一个物理共享信道的数据的多个控制信息同时承载于第一配置信息中,有助于减少通信时延,节省信令开销。Specifically, the first configuration information includes or itself configures the SPS-config signaling for the above-mentioned SPS, and the present application may add a field retransmissionSelfContainedControlIE in the field to indicate that the method can be applied to a retransmission scenario. Further, the MCS parameter, the HARQ-ProcessesID parameter, the NDI parameter or the RV parameter may be added to the retransmissionSelfContainedControlIE as described above. For the meanings corresponding to each parameter, please refer to the above description. For the sake of brevity, details are not repeated here. For other parameters in the first configuration information, reference may be made to the TS38.331 protocol in the current 3GPP standard. The sending end device (that is, the second communication device) sends the first configuration information to the receiving end device (that is, the first communication device), and the receiving end device can apply the technical solution to the retransmissionSelfContainedControlIE parameter in the first configuration information. Pass the scene. Specifically, after the retransmissionSelfContainedControlIE field is configured and the receiving end device determines that the currently received data is retransmission data, it can decode the MCS parameter, HARQ-ProcessesID parameter, NDI parameter or RV parameter of the control information in the first physical shared channel, The information indicated by the corresponding parameter is acquired so as to decode the data in the first physical shared channel. Simultaneously carrying multiple pieces of control information about the data of the same physical shared channel in the first configuration information helps to reduce communication delay and save signaling overhead.
