Description
本申请要求于2021年8月06日提交中国专利局、申请号为202110903586.2、申请名称为“一种获取信息的方法和装置”的中国专利申请的优先权,其全部内容通过引用结合在本申请中。This application claims the priority of the Chinese patent application with the application number 202110903586.2 and the application title "A Method and Device for Obtaining Information" submitted to the China Patent Office on August 06, 2021, the entire contents of which are incorporated by reference in this application middle.
本申请涉及通信技术的领域,并且更具体地,涉及一种获取信息的方法和装置。The present application relates to the field of communication technology, and more specifically, to a method and device for acquiring information.
为了提升小区边缘用户体验,当为终端设备的服务小区有多个时,终端设备既可以选择单接收传输点模式(single transmission and reception point,STRP),也可以采用多接收传输点模式(multiple transmission and reception point,MTRP)工作。其中,MTRP模式中配置的用于调度数据的下行控制信息(downlink control information,DCI)的比特长度可能要长于在STRP模式中使用的DCI。例如,3GPP 5G NR Rel-17版本,MTRP模式中使用的DCI需要指示2个接收传输点(transmission and reception point,TRP)时,与STRP模式中使用的DCI相比,DCI需要新增8至14个比特。In order to improve user experience at the edge of the cell, when there are multiple serving cells for the terminal device, the terminal device can either choose the single transmission and reception point (STRP) mode or the multiple transmission point mode (multiple transmission point). and reception point, MTRP) work. Wherein, the bit length of downlink control information (DCI) configured in the MTRP mode for scheduling data may be longer than that of the DCI used in the STRP mode. For example, in the 3GPP 5G NR Rel-17 version, when the DCI used in MTRP mode needs to indicate two receiving transmission points (transmission and reception point, TRP), compared with the DCI used in STRP mode, DCI needs to add 8 to 14 bits.
目前,当终端设备从MTRP模式切换到STRP模式时,终端设备接收到的DCI可能仍然包括多个TRP的信息,终端设备可以对DCI中相应的指示域的后半部分进行截取,使得DCI的长度与STRP模式下配置的DCI的长度相同,然后再进行解读获得该TRP的信息。当终端设备从STRP模式切换到MTRP模式时,终端设备接收到的DCI中包括多个TRP的信息,终端设备可以对DCI中相应的指示域进行补零,使得DCI的长度与MTRP模式下配置的DCI的长度相同,然后再进行解读获得多个TRP的信息。At present, when a terminal device switches from MTRP mode to STRP mode, the DCI received by the terminal device may still include information about multiple TRPs, and the terminal device can intercept the second half of the corresponding indication field in the DCI so that the length of the DCI It is the same length as the DCI configured in STRP mode, and then it is interpreted to obtain the information of the TRP. When the terminal device switches from STRP mode to MTRP mode, the DCI received by the terminal device includes information of multiple TRPs, and the terminal device can pad the corresponding indication field in the DCI so that the length of the DCI is the same as that configured in MTRP mode. The length of the DCI is the same, and then it is interpreted to obtain the information of multiple TRPs.
但是,终端设备在MTRP模式与STRP模式进行切换,采用补零或者截取的方式不具有灵活性,并且,当在DCI中包括多个TRP的信息,且用于指示每个TRP的信息的比特长度不同时,采用补零或者截取的方式会存在无法解读的可能,因袭,亟需一种获取信息的方法,在切换时能够灵活准确的获取控制信息中的信息。However, when a terminal device switches between MTRP mode and STRP mode, it is not flexible to use zero padding or truncation, and when the DCI includes multiple TRP information and is used to indicate the bit length of each TRP information At the same time, there is a possibility that it cannot be interpreted in the way of zero padding or interception, and there is an urgent need for a method of obtaining information that can flexibly and accurately obtain the information in the control information when switching.

当前,为了进一步增强MTRP的性能,Rel-17定义了物理上行共享信道(physical uplink shared channel,PUSCH)增强的方案。通过扩展DCI(例如格式DCI 0_1,DCI 0_2,DCI 1_1或DCI 1_2)中相应指示域的比特字段,使得DCI能够指示2个TRP的信息,从而可以支持采用两个TPR传输数据的方案。以下列出了支持两个TRP的DCI中需要扩展的指示域:Currently, in order to further enhance the performance of MTRP, Rel-17 defines a physical uplink shared channel (physical uplink shared channel, PUSCH) enhancement scheme. By extending the bit field of the corresponding indication field in the DCI (such as format DCI 0_1, DCI 0_2, DCI 1_1 or DCI 1_2), the DCI can indicate the information of 2 TRPs, thereby supporting the scheme of using two TPRs to transmit data. The indication fields that need to be extended in a DCI supporting two TRPs are listed below:
1.传输功率控制(transmission power control,TPC)1. Transmission power control (TPC)
该TPC字段由2个比特扩展到4个比特。指示两个TRP的其中一种方式为:该TPC字段包括两个TPC域,第一个TPC域包括原来的2个比特,用于指示一个TRP的信息,另一个TPC域包括新增的2个比特,指示另一个TRP的信息;另一种方式为该TPC字段中的4个比特组成一个TPC域,该一个TPC域指示两个TPC的信息。需要说明的是,可以通过RRC配置一个信息用于指示包括新增的2个比特的TPC域是否存在,或者说指示采用哪一种方式指示两个TRP的信息。The TPC field is extended from 2 bits to 4 bits. One of the ways to indicate two TRPs is: the TPC field includes two TPC fields, the first TPC field includes the original 2 bits, which are used to indicate the information of a TRP, and the other TPC field includes the newly added 2 bits The bit indicates information of another TRP; another mode is that 4 bits in the TPC field form a TPC field, and the one TPC field indicates information of two TPCs. It should be noted that, RRC may be used to configure a piece of information to indicate whether the TPC field including the newly added 2 bits exists, or to indicate which method is used to indicate the information of two TRPs.
2.信道探测参考信号资源指示(sounding reference signal resource indicator,SRI)2. Channel sounding reference signal resource indicator (sounding reference signal resource indicator, SRI)
该SRI字段可基于原来配置的比特数量增加1至3个比特。该SRI字段包括两个SRI域,第一个SRI域包括原来的比特,与一个SRS resource set相关联,用于指示一个TRP的相关信息,另一个SRI域包括新增的比特,与另一个不同的SRS resource set相关联,指示另一个TRP的相关信息。The SRI field may be increased by 1 to 3 bits based on the originally configured number of bits. The SRI field includes two SRI fields, the first SRI field includes the original bits, associated with an SRS resource set, and is used to indicate the relevant information of a TRP, and the other SRI field includes newly added bits, which are different from the other Associated with the SRS resource set of the SRS, indicating the relevant information of another TRP.
需要说明的是,两个SRI域的长度可以相同也可以不同,或者说,新增的比特数量与原来的比特数量可以相同也可以不同。It should be noted that the lengths of the two SRI fields may be the same or different, or in other words, the number of newly added bits may be the same as or different from the original number of bits.
例如,当采用码本方式进行传输时,如果与两个SRI域相关联的两个SRS resource set中的资源的个数相同,那么两个SRI域的长度相同;如果两个SRS resource set中的资源的个数不相同,那么两个SRI域的长度也不相同,分别等于log[N],其中N为与之相关联的SRS resource set中的资源的个数。For example, when using the codebook method for transmission, if the number of resources in the two SRS resource sets associated with the two SRI domains is the same, then the lengths of the two SRI domains are the same; if the resources in the two SRS resource sets If the number of resources is different, the lengths of the two SRI domains are also different, which are equal to log[N] respectively, where N is the number of resources in the associated SRS resource set.
作为示例而非限定,针对STRP模式传输,SRI字段包括一个SRI域,与一个SRS resource set相关联,该SRS resource set中的资源的最大数目为4;针对MTRP模式传输,SRI字段包括两个SRI域,分别关联两个SRS resource set,每个SRS resource set中的资源的最大数目为4。表1至表3分别示出了一个SRI域的映射索引列表,其中,表1中SRI域所关联的SRS resource set中包括2个资源,表2中SRI域所关联的SRS resource set中包括3个资源,表3中SRI域所关联的SRS resource set中包括4个资源。As an example and not limitation, for STRP mode transmission, the SRI field includes an SRI field, associated with an SRS resource set, and the maximum number of resources in the SRS resource set is 4; for MTRP mode transmission, the SRI field includes two SRI Domains are associated with two SRS resource sets respectively, and the maximum number of resources in each SRS resource set is 4. Tables 1 to 3 respectively show a mapping index list of an SRI domain, wherein the SRS resource set associated with the SRI domain in Table 1 includes 2 resources, and the SRS resource set associated with the SRI domain in Table 2 includes 3 resources. resources, the SRS resource set associated with the SRI domain in Table 3 includes 4 resources.

再例如,当采用基于非码本方式进行传输时,可以根据第一个SRI域确定第二个SRI域包括的比特的个数。此时,定义指示的两个TRP传输信息的层数相同,则可以根据第一个SRI域所指示的对应的层数的最大SRI编码点数确定第二个SRI域包括的比特的个数。For another example, when the non-codebook-based transmission is adopted, the number of bits included in the second SRI field may be determined according to the first SRI field. At this time, if the layers of the two TRP transmission information indicated by the definition are the same, the number of bits included in the second SRI field can be determined according to the maximum number of SRI code points of the corresponding layer number indicated by the first SRI field.
作为示例而非限定,针对STRP模式传输,SRI字段包括一个SRI域,与一个SRS resource set相关联,该SRS resource set中的资源的最大数目为4;针对MTRP模式传输,SRI字段包括两个SRI域,分别关联两个SRS resource set,每个SRS resource set中的资源的最大数目为4。表4至表7分别示出了一个SRI域不同最大层数(分别为1层、2层、3层和4层)的映射索引列表。As an example and not limitation, for STRP mode transmission, the SRI field includes an SRI field, associated with an SRS resource set, and the maximum number of resources in the SRS resource set is 4; for MTRP mode transmission, the SRI field includes two SRI Domains are associated with two SRS resource sets respectively, and the maximum number of resources in each SRS resource set is 4. Table 4 to Table 7 respectively show the mapping index lists of different maximum layers (layer 1, layer 2, layer 3 and layer 4) in an SRI domain.

表6:Table 6:
表7:Table 7:
3.传输预编码矩阵指示(transmitted precoding matrix indicator,TPMI)3. Transmission precoding matrix indicator (transmitted precoding matrix indicator, TPMI)
该TPMI字段可基于原来配置的比特数量增加1至5个比特。该TPMI字段包括两个TPMI域,第一个TPMI域包括原来的比特,TPMI域通常采用基于码本的传输方式,即可以根据第一个TPMI域确定第二个TPMI域包括的比特的个数,也就是新增的比特个数,例如,可以根据第一个TPMI域所指示的该层中的最大TPMI编码点数确定第二个TPMI域包括的比特的个数。具体地,表8示出了一个TPMI域的映射索引列表,其中,fullyAndPartialAndNonCoherent、partialAndNonCoherent、nonCoherent三个参数可以通过RRC进行配置,也就是说,作为示例,终端设备可以根据该三个参数的配置确定采用表8中三列映射索引中的哪一列对TPMI域进行解读。The TPMI field may be increased by 1 to 5 bits based on the originally configured number of bits. The TPMI field includes two TPMI fields, the first TPMI field includes the original bits, and the TPMI field usually adopts a codebook-based transmission method, that is, the number of bits included in the second TPMI field can be determined according to the first TPMI field , that is, the number of newly added bits. For example, the number of bits included in the second TPMI field may be determined according to the maximum number of TPMI code points in the layer indicated by the first TPMI field. Specifically, Table 8 shows a mapping index list of a TPMI domain, where the three parameters fullyAndPartialAndNonCoherent, partialAndNonCoherent, and nonCoherent can be configured through RRC, that is to say, as an example, the terminal device can determine according to the configuration of the three parameters Which column of the three-column mapping index in Table 8 is used to interpret the TPMI domain.
表8:Table 8:
4.相位跟踪参考信号-解调参考信号(phase tracking reference signals-demodulationreference signal,PTRS-DMRS)关系4. Phase tracking reference signal-demodulation reference signal (phase tracking reference signals-demodulation reference signal, PTRS-DMRS) relationship
当该PTRS-DMRS字段的maxRank等于2时,不再新增比特,复用原来的比特指示两个TRP的相关信息,例如,利用MSB和LSB分别指示两个TRP的相关信息;当该maxRank大于2时,可以新增一个PTRS-DMRS域,例如,原来的比特组成一个PTRS-DMRS域,新增2个比特组成另一个PTRS-DMRS域,两个PTRS-DMRS域分别指示两个TRP的相关信息。目前相关协议对PTRS-DMRS域也定义了相关的映射索引列表,为了简便,在此不再赘述。When the maxRank of the PTRS-DMRS field is equal to 2, no new bits are added, and the original bits are reused to indicate the relevant information of the two TRPs, for example, the MSB and LSB are used to indicate the relevant information of the two TRPs respectively; when the maxRank is greater than 2, you can add a PTRS-DMRS field, for example, the original bits form a PTRS-DMRS field, and add 2 bits to form another PTRS-DMRS field, and the two PTRS-DMRS fields indicate the correlation between the two TRPs respectively. information. At present, relevant protocols also define a related mapping index list for the PTRS-DMRS domain, which will not be repeated here for simplicity.
5.STRP和MTRP动态转换(dynamic switching between STRP and MTRP)5. Dynamic switching between STRP and MTRP (dynamic switching between STRP and MTRP)
该字段包括2个比特,用于指示MTRP模式下MTRP操作与STRP操作之间发生切换,表9示出了该字段的定义。This field includes 2 bits, and is used to indicate switching between MTRP operation and STRP operation in MTRP mode. Table 9 shows the definition of this field.
表9:Table 9:
根据当前协议TS 38.212和TS 38.213,用于激活部分带宽(bandwidth part,BWP)的DCI中包括一个或多个指示域。当不同的BWP配置不同的TRP传输模式时,例如,BWP#1配置STRP模式进行传输,BWP#2配置MTRP模式进行传输,从上述可知,BWP#1中的DCI#1和BWP#2中的DCI#2存在的一个或多个指示域以及相应的字段的长度将有所不同。According to the current protocols TS 38.212 and TS 38.213, the DCI used to activate the bandwidth part (BWP) includes one or more indication fields. When different BWPs configure different TRP transmission modes, for example, BWP# 1 configures STRP mode for transmission, and BWP#2 configures MTRP mode for transmission. From the above, it can be seen that DCI# 1 in BWP# 1 and DCI in BWP#2 The lengths of one or more indication fields present in DCI#2 and the corresponding fields will be different.
当从BWP#1切换到BWP#2,STRP模式切换到MTRP模式时:When switching from BWP# 1 to BWP#2, STRP mode switches to MTRP mode:
终端设备需要从接收到的DCI#1中获取两个TRP的信息,终端设备可以将DCI#1中短于DCI#2的指示域进行在前补零,使得DCI#1中相应的指示域的长度与DCI#2中的一致,然后终端设备进行解读,获取两个TRP的信息。The terminal device needs to obtain two TRP information from the received DCI# 1, and the terminal device can pad the indication field shorter than DCI#2 in DCI# 1 with zeros in front, so that the corresponding indication field in DCI# 1 The length is consistent with that in DCI#2, and then the terminal device interprets it to obtain the information of the two TRPs.
为了清楚,以DCI中的SRI域进行举例,假设DCI#1中的SRI#1的长度为3个比特,DCI#2中的SRI#2的长度为6个比特,若终端设备接收到的SRI#1为“011”,则将其进行补零变为“000011”后进行解读。For clarity, take the SRI field in DCI as an example. Assume that the length of SRI# 1 in DCI# 1 is 3 bits, and the length of SRI#2 in DCI#2 is 6 bits. If the terminal device receives the SRI # 1 is "011", then it will be interpreted after zero padding to "000011".
当从BWP#2切换到BWP#1,MTRP模式切换到STRP模式时:When switching from BWP#2 to BWP# 1, MTRP mode switches to STRP mode:
终端设备接收到的DCI#2中可能仍然包括两个TRP的信息,终端设备只需要一个TRP的信息,终端设备可以对DCI#1中长于DCI#2的指示域进行在后截取,使得DCI#1中相应的指示域的长度与DCI#2中的一致,然后终端设备进行解读,获取一个TRP的信息。The DCI#2 received by the terminal device may still include two TRP information, and the terminal device only needs one TRP information, and the terminal device can intercept the indication field longer than DCI#2 in DCI# 1, so that DCI# The length of the corresponding indication field in 1 is consistent with that in DCI#2, and then the terminal device interprets it to obtain the information of a TRP.
为了清楚,以DCI中的SRI域进行举例,假设DCI#1中的SRI#1的长度为6个比特,DCI#2中的SRI#2的长度为3个比特,若终端设备接收到的SRI#1为“011101”,则截取其后三位变为“101”后进行解读。For clarity, take the SRI field in DCI as an example. Assume that the length of SRI# 1 in DCI# 1 is 6 bits, and the length of SRI#2 in DCI#2 is 3 bits. If the terminal device receives the SRI # 1 is "011101", then intercept the last three digits and change it to "101" for interpretation.
但是,这种模式切换时获取信息的方式不够灵活,且容易出现错误,例如总是前置补0的话可能会出现指示错误。并且,在DCI中的某个指示域中包括两个域分别指示两个TRP的信息,且该两个域包括的比特的个数不同的情况下,补零或者截取的方式可能无法获取正确的信息。为了清楚,以下以SRI指示域进行举例说明,假设DCI#1所属的BWP#1配置STRP模式,DCI#1中SRI#1为一个指示域,SRI#1包括3个比特;假设DCI#2所属的BWP#2配置MTRP模式,DCI#2中SRI#2包括SRI域#21和SRI域#22,SRI域#21和SRI域#22分别用于指示TRP#1和TRP#2的信息,该SRI域#21包括3个比特,该SRI域#22包括2个比特。However, this way of obtaining information when switching modes is not flexible enough, and is prone to errors, for example, if always prepending 0, an indication error may occur. In addition, when a certain indication field in the DCI includes two fields respectively indicating two TRP information, and the number of bits included in the two fields is different, zero padding or truncation may not be able to obtain the correct information. For clarity, the following uses the SRI indicator field as an example. Assume that BWP# 1 to which DCI# 1 belongs is configured with STRP mode. SRI# 1 in DCI# 1 is an indicator field, and SRI# 1 includes 3 bits; assume that DCI#2 belongs BWP#2 of BWP#2 configures MTRP mode, SRI#2 in DCI#2 includes SRI field #21 and SRI field #22, and SRI field #21 and SRI field #22 are used to indicate the information of TRP# 1 and TRP#2 respectively, the The SRI field #21 includes 3 bits, and the SRI field #22 includes 2 bits.
若从BWP#1切换到BWP#2,STRP模式切换到MTRP模式,终端设备接收到SRI#1,终端设备无法判断需要在前补零的个数,或者说无法知道需要在SRI#1的前面补2个0才与SRI#2包括的比特数目相同,从而终端设备无法从DCI#1中获取正确的两个TRP的信息。If you switch from BWP# 1 to BWP#2, switch from STRP mode to MTRP mode, and the terminal device receives SRI# 1, the terminal device cannot determine the number of zeros that need to be added before SRI# 1, or it cannot know that it needs to be in front of SRI# 1 The number of bits included in SRI#2 is the same as the number of bits included in SRI#2 by adding two 0s, so that the terminal device cannot obtain correct information of two TRPs from DCI# 1.
若从BWP#2切换到BWP#1,MTRP模式切换到STRP模式,终端设备接收到SRI#2,SRI#2包括3个比特的SRI域#21和2个比特的SRI域#22,终端设备无法判断需要截取的比特的位数,从而终端设备无法从DCI#2中获取正确的所需的TRP的信息。If switching from BWP#2 to BWP# 1, the MTRP mode switches to STRP mode, the terminal device receives SRI#2, and SRI#2 includes 3-bit SRI field #21 and 2-bit SRI field #22, the terminal device The number of bits to be truncated cannot be judged, so the terminal equipment cannot obtain correct required TRP information from DCI#2.
因此,亟需一种获取信息的方法,在切换时能够灵活准确的获取控制信息中所需要的信息。Therefore, there is an urgent need for a method for obtaining information, which can flexibly and accurately obtain the information required in the control information during switching.
图2示出了一种本申请提出的获取信息的方法200的示意性流程图。FIG. 2 shows a schematic flow chart of a method 200 for acquiring information proposed in this application.
该方法应用于支持第一配置和第二配置的通信***中,当该***在第一配置和第二配置之间进行切换时,该方法200包括步骤S210至S240。The method is applied in a communication system supporting the first configuration and the second configuration. When the system switches between the first configuration and the second configuration, the method 200 includes steps S210 to S240.
可选地,所述第一配置为单接收传输点模式的配置,所述第二配置为多接收传输点模式的配置,和/或,Optionally, the first configuration is a configuration of a single receiving transmission point mode, and the second configuration is a configuration of a multi-receiving transmission point mode, and/or,
所述第一配置为多接收传输点模式下的配置,所述第二配置为单接收传输点模式下的配置,和/或,The first configuration is a configuration in a multi-reception transmission point mode, and the second configuration is a configuration in a single reception transmission point mode, and/or,
所述第一配置和所述第二配置分别为相同或不同的频带宽度部分的配置,和/或,The first configuration and the second configuration are configurations of the same or different frequency bandwidth parts respectively, and/or,
所述第一配置和所述第二配置分别为相同或不同的载波的配置,和/或,The first configuration and the second configuration are respectively the same or different carrier configurations, and/or,
所述第一配置和所述第二配置分别为相同或不同的小区的配置,和/或,The first configuration and the second configuration are configurations of the same or different cells respectively, and/or,
所述第一配置和所述第二配置分别为相同或不同的时域格式的配置。The first configuration and the second configuration are configurations of the same or different time domain formats respectively.
例如,第一配置和第二配置之间的切换可以是STRP模式和MTRP模式之间的切换,也可以是不同的BWP之间的切换,配置STRP模式的BWP与配置MTRP模式的BWP之间的切换,也可以是不同的载波之间的切换,配置STRP模式的载波与配置MTRP模式的载波之间的切换,也可以是不同的小区之间的切换,配置STRP模式的小区与配置MTRP模式的小区之间的切换,还可以是BWP和小区之间的切换,BWP和载波之间的切换,或者是小区和载波之间的切换等。For example, the switch between the first configuration and the second configuration may be a switch between STRP mode and MTRP mode, or a switch between different BWPs. The BWP configured with STRP mode and the BWP configured with MTRP mode Handover can also be a handover between different carriers, a handover between a carrier configured with STRP mode and a carrier configured with MTRP mode, or a handover between different cells, between a cell configured with STRP mode and a carrier configured with MTRP mode The handover between cells may also be a handover between a BWP and a cell, a handover between a BWP and a carrier, or a handover between a cell and a carrier.
第一配置或第二配置可以理解为有一种BWP、载波或小区,也可以理解为一种BWP、载波或小区的配置,或者说是一种BWP、载波或小区下的配置。需要说明的是,第一配置和第二配置为不同的配置,具有不同的解读信息的模式和或格式,***在第一配置和第二配置之间进行切换时,终端设备可能需要改变对接收到的信息的解读方式。The first configuration or the second configuration can be understood as having a BWP, carrier or cell, or as a configuration of the BWP, carrier or cell, or a configuration under the BWP, carrier or cell. It should be noted that the first configuration and the second configuration are different configurations and have different modes and or formats for interpreting information. When the system switches between the first configuration and the second configuration, the terminal device may need to change the How to interpret the information received.
S210,终端设备接收第一配置下的第一控制信息。S210. The terminal device receives first control information under the first configuration.
例如,终端设备从接入网设备#1接收第一配置下的第一控制信息,对应地,接入网设备#1向终端设备发送第一配置下的第一控制信息。For example, the terminal device receives the first control information under the first configuration from the access network device # 1, and correspondingly, the access network device # 1 sends the first control information under the first configuration to the terminal device.
需要说明的是,该第一控制信息的配置方式采用第一配置的方式,但该第一控制信息携带的信息是关于第二配置下的信息,也就是说,终端设备接收到的第一控制信息,可以不采用第一配置的方式对第一控制信息进行解读,而采用其它方式对第一控制信息进行解读以获取所需要的信息。It should be noted that the configuration method of the first control information adopts the first configuration method, but the information carried in the first control information is information about the second configuration, that is, the first control information received by the terminal device information, the first control information may not be interpreted in the manner of the first configuration, but the first control information may be interpreted in other ways to obtain the required information.
也就是说,不同模式下的控制信息的大小或者格式不同,例如,STRP模式下的DCI中的一些指示域包括的比特的个数要少于MTRP模式下的该指示域包括的比特的个数。第一配置下的控制信息调度第二配置下的信道时,终端设备需要将第一配置下的控制信息转化为第二配置,再进行解读获取所需要的第二控制信息。That is to say, the size or format of the control information in different modes is different. For example, the number of bits included in some indication fields in the DCI in STRP mode is less than the number of bits included in the indication field in MTRP mode. . When the control information in the first configuration schedules the channel in the second configuration, the terminal device needs to convert the control information in the first configuration into the second configuration, and then interpret and obtain the required second control information.
可选地,终端设备接收切换信息,该切换信息用于指示从第一配置切换到第二配置。Optionally, the terminal device receives switching information, where the switching information is used to indicate switching from the first configuration to the second configuration.
S220,终端设备根据第一控制信息确定第二配置下的第一信道的传输。S220. The terminal device determines transmission of the first channel under the second configuration according to the first control information.
需要说明的是,第一信道可以是PUSCH、PDSCH、PUCCH或者PDCCH等,第一信道也可以理解成需要传输的数据或者信令,本申请对此不作限定。It should be noted that the first channel may be PUSCH, PDSCH, PUCCH, or PDCCH, etc., and the first channel may also be understood as data or signaling that needs to be transmitted, which is not limited in this application.
为了清楚,以下以在STRP模式和在MTRP模式之间切换的场景进行举例,本申请实施例用于在不同的小区间进行切换和在不同的载波间进行切换的方式类似,为了简便,在此不再赘述。For clarity, the following is an example of switching between STRP mode and MTRP mode.

作为示例而非限定,第一比特字段与第三比特资源相同可以理解为第一比特指端和第二比特字段的长度相同,和/或比特值相同,和/或所指示的内容的关联或映射关系相同。As an example and not a limitation, the fact that the first bit field is the same as the third bit resource can be understood as the length of the first bit finger and the second bit field are the same, and/or the bit values are the same, and/or the association of the indicated content or The mapping relationship is the same.
第二比特字段可以是一个或多个,例如,该第二比特字段为SRI域,该第一个或多个SRI域可以分别对应一个或多个SRS资源集合(SRS resource set),为了清楚,以下以一个第二比特字段进行介绍。The second bit field can be one or more, for example, the second bit field is an SRI domain, and the first or more SRI domains can respectively correspond to one or more SRS resource sets (SRS resource set), for clarity, A second bit field is used for introduction below.
方式1:Method 1:
第二比特字段与第一比特字段为相同的比特字段。The second bit field is the same bit field as the first bit field.
需要说明的是,第一比特字段和第二比特字段为相同的比特字段,是指第一比特字段和第二比特字段包括的比特相同,但是第一比特字段和第二比特字段解释出来的信息可以不用,例如,参见图3,图3示出了第一控制信息包括的字段为SRI字段进行切换的示意性结构图,当第一控制信息包括的字段为SRI字段时,第一比特字段和第二比特字段关联不同的SRS resource set,若第一控制信息为0111,则第二控制信息有第一比特字段和第二比特字段组成,为01110111。It should be noted that the first bit field and the second bit field are the same bit field, which means that the bits included in the first bit field and the second bit field are the same, but the information interpreted by the first bit field and the second bit field It may not be used. For example, refer to FIG. 3. FIG. 3 shows a schematic structural diagram of switching the field included in the first control information as the SRI field. When the field included in the first control information is the SRI field, the first bit field and The second bit field is associated with different SRS resource sets. If the first control information is 0111, the second control information consists of the first bit field and the second bit field, which is 01110111.
方式2:Method 2:
第二比特字段的长度为第一长度,该第一长度是根据第一比特字段确定的。The length of the second bit field is the first length, and the first length is determined according to the first bit field.
第二比特字段为从所述第一比特字段的最高有效位开始截取获得的第一长度的比特字段,The second bit field is a bit field of the first length obtained by intercepting from the most significant bit of the first bit field,
或者,第二比特字段为从所述第一比特字段的最低有效位开始截取获得的所述第一长度的比特字段,其中,所述第一长度是根据所述第一比特字段确定的。Alternatively, the second bit field is a bit field of the first length obtained by truncating from the least significant bit of the first bit field, where the first length is determined according to the first bit field.
作为示例而非限定,以第一控制信息包括SRI域进行举例,假设SRI域的配置方式为基于非码本传输,最大层数为2,1个SRS recourse set包括4个资源,其映射索引表为表5所示的第5列和第6列(可以参见表10):As an example and not a limitation, take the first control information including the SRI domain as an example, assuming that the configuration of the SRI domain is based on non-codebook transmission, the maximum number of layers is 2, and one SRS recourse set includes 4 resources, and its mapping index table Columns 5 and 6 shown in Table 5 (see Table 10):
表10:Table 10:
比特字段bit field | 对应的取值corresponding value | SRI(s),N SRS=4 SRI(s), N SRS =4 |
00000000 | 00 | 00 |
00010001 | 11 | 11 |
00100010 | 22 | 22 |
00110011 | 33 | 33 |
01000100 | 44 | 0,10,1 |
01010101 | 55 | 0,20,2 |
01100110 | 66 | 0,30,3 |
01110111 | 77 | 1,21,2 |
10001000 | 88 | 1,31,3 |
10011001 | 99 | 2,32,3 |
1010-11111010-1111 | 10-1510-15 | reservedreserved |
可选地,第一长度为所述第一比特字段所述的第一集合对于的最大编码点,第一集合为包括的层数相同的比特字段。Optionally, the first length is the maximum code point of the first set described by the first bit field, and the first set is a bit field including the same number of layers.
例如,在表10中,对应的取值为0至3的比特字段对应的层数为1,对应的取值为4至9的比特字段对应的层数为2,则第一集合可以是包括比特字段0000至0011的集合,也可以是包括比特字段0100至1001的集合。For example, in Table 10, the layer number corresponding to the bit field with a corresponding value from 0 to 3 is 1, and the corresponding layer number to a bit field with a corresponding value from 4 to 9 is 2, then the first set may include The set of bit fields 0000 to 0011 may also be a set including bit fields 0100 to 1001.
再例如,以第一控制信息包括TPMI字段进行举例,假设TPMI字段的配置方式为基于码本传输,其映射索引表采用表8所示的第5列和第6列。对应的取值为0至3的比特字段对应的层数为1,对应的取值为4至9的比特字段对应的层数2,类似地,第一集合可以是包括比特字段0000至0011的集合,也可以是包括比特字段0100至1001的集合。For another example, taking the first control information including the TPMI field as an example, assuming that the configuration mode of the TPMI field is based on codebook transmission, the mapping index table adopts the fifth column and the sixth column shown in Table 8. The corresponding bit field with a value of 0 to 3 corresponds to a layer number of 1, and the corresponding bit field with a value of 4 to 9 corresponds to a layer number of 2. Similarly, the first set may include bit fields 0000 to 0011 A set may also be a set including bit fields 0100 to 1001.
需要说明的是,以上仅是以SRI字段和TPMI字段进行举例,第一控制信息还可以包括其它字段,其确定第一比特字段和第二比特字段的方式与之类似,为了简便,在此不再赘述。It should be noted that the above is only an example of the SRI field and the TPMI field. The first control information may also include other fields, and the method for determining the first bit field and the second bit field is similar. Let me repeat.
第一长度为所述第一比特字段所述的第一集合对于的最大编码点,可以理解为终端设备根据第一集合中包括的比特字段的个数确定第一集合对应的第一长度。The first length is the maximum code point of the first set described by the first bit field. It can be understood that the terminal device determines the first length corresponding to the first set according to the number of bit fields included in the first set.
例如,若第一集合包括比特字段0000至0011共4个比特字段,该4个比特字段最少需要2个比特进行索引,此时,第一长度为2;若第一集合包括比特字段0100至1001共6个比特字段,该6个比特字段最少需要3个比特进行索引,此时,第一长度为3。For example, if the first set includes 4 bit fields of bit fields 0000 to 0011, the 4 bit fields require at least 2 bits for indexing, and at this time, the first length is 2; if the first set includes bit fields 0100 to 1001 There are 6 bit fields in total, and the 6 bit fields require at least 3 bits for indexing. In this case, the first length is 3.
例如,参见图4,若第二比特字段为从所述第一比特字段的最高有效位开始截取获得的所述第一长度的比特字段,假设第一比特字段为0111,该第一比特字段属于第一集合,该第一集合对应的第一长度为3,在这种情况下,第二比特字段为011。For example, referring to FIG. 4, if the second bit field is a bit field of the first length obtained by intercepting from the most significant bit of the first bit field, assuming that the first bit field is 0111, the first bit field belongs to The first set, the first length corresponding to the first set is 3, in this case, the second bit field is 011.
例如,参见图5,若第二比特字段为从所述第一比特字段的最低有效位开始截取获得的所述第一长度的比特字段,假设,第一比特字段为0111,该第一比特字段属于第一集合,该第一集合对应的第一长度为3,在这种情况下,第二比特字段为111。For example, referring to FIG. 5, if the second bit field is a bit field of the first length obtained by intercepting from the least significant bit of the first bit field, it is assumed that the first bit field is 0111, and the first bit field belongs to the first set, and the first length corresponding to the first set is 3, in this case, the second bit field is 111.
方式3:Method 3:
第一比特字段属于第二集合,该第二比特字段为第二集合中的多个比特字段中的一个。The first bit field belongs to the second set, and the second bit field is one of the plurality of bit fields in the second set.
例如,第二集合可以是包括对应的取值在预设范围内的比特字段。For example, the second set may include bit fields whose corresponding values are within a preset range.
有关第二集合的描述与第一集合的描述类似,为了简便,在此不再赘述。The description about the second set is similar to the description of the first set, and for the sake of brevity, details are omitted here.
作为示例而非限定,仍以第一控制信息包括SRI字段进行举例,假设第二集合是对应的取值为4至9的比特字段,即比特字段0100至1001,那么第二比特字段可以为比特字 段0100至1001中的任意一个。As an example but not a limitation, the first control information includes the SRI field as an example, assuming that the second set is a corresponding bit field with a value of 4 to 9, that is, a bit field 0100 to 1001, then the second bit field can be a bit field Any one of fields 0100 to 1001.
在一种可能的实现方式中,第二比特字段为所述第二集合中对应的取值最大的比特字段。In a possible implementation manner, the second bit field is a bit field corresponding to a maximum value in the second set.
例如,第一比特字段为1000,该第二比特字段属于第二集合,第二集合是对应的取值为4至9的比特字段,此时,第二比特字段为对应的取值为9的比特字段1001。For example, the first bit field is 1000, the second bit field belongs to the second set, and the second set is a corresponding bit field with a value of 4 to 9. At this time, the second bit field is a corresponding value of 9 bit field 1001.
在另一种可能的实现方式中,第二比特字段为所述第二集合中对应的取值最小的比特字段。In another possible implementation manner, the second bit field is a corresponding minimum value bit field in the second set.
例如,第一比特字段为1000,该第二比特字段属于第二集合,第二集合是对应的取值为4至9的比特字段,此时,第二比特字段为对应的取值为4的比特字段0100。For example, the first bit field is 1000, the second bit field belongs to the second set, and the second set is a corresponding bit field with a value of 4 to 9. At this time, the second bit field is a corresponding value of 4 Bit field 0100.
方式1至方式3中的根据第一控制信息确定第二控制信息,可以理解为在原有的第一控制信息包括的比特字段的基础上进行扩展,第二控制信息仍会包括原有的比特字段。Determining the second control information based on the first control information in modes 1 to 3 can be understood as expanding on the basis of the bit fields included in the original first control information, and the second control information will still include the original bit fields .
方式4至方式7中,终端设备可以直接根据第一控制信息确定第二配置下的第一信道的传输,以下将对方式4至方式7分别进行介绍。In mode 4 to mode 7, the terminal device may directly determine the transmission of the first channel under the second configuration according to the first control information, and mode 4 to mode 7 will be introduced respectively below.
方式4:Method 4:
根据第一控制信息确定第二配置下的第一信道的传输,包括:Determining the transmission of the first channel under the second configuration according to the first control information includes:
对所述第一控制信息进行联合解码,以获得第二配置下的第一信道的传输。Perform joint decoding on the first control information to obtain transmission of the first channel under the second configuration.
所述第一控制信息是通过联合编码获得的。The first control information is obtained through joint coding.
作为示例而非限定,该第一控制信息为一个SRI域,该一个SRI域用于指示MTRP模式中的2个接入网设备,该第一控制信息是通过对2个接入网设备关联的指示域进行联合编码获得的。假设SRI字段的配置方式为每个SRS resource set包括4个资源,则可以参照表11根据两个接入网设备对应的SRI域的取值获取联合编码点,也就是第一控制信息对应的取值或者说是编码点。As an example but not a limitation, the first control information is an SRI field, which is used to indicate two access network devices in MTRP mode, and the first control information is associated with the two access network devices Indicates that the domains are jointly encoded. Assuming that the SRI field is configured in such a way that each SRS resource set includes 4 resources, you can refer to Table 11 to obtain the joint code point according to the values of the SRI fields corresponding to the two access network devices, that is, the value corresponding to the first control information value or code point.
表11:Table 11:
可选地,可以通过RRC配置联合编码点的索引映射列表,例如,通过RRC配置0-63个联合编码点以及对应的两个SRI域对应的取值组合,再通过MAC-CE确定与SRI字段的比特长度相对应的编码点,例如,包括4个比特的第一控制信息对应的联合编码点最多可以有16个。Optionally, the index mapping list of joint code points can be configured through RRC, for example, 0-63 joint code points and corresponding value combinations corresponding to the two SRI fields can be configured through RRC, and then the MAC-CE can be used to determine the corresponding value combination with the SRI field The code points corresponding to the bit length, for example, there may be 16 joint code points corresponding to the first control information including 4 bits at most.
在一种可能的实现方式中,接入网设备可以根据配置的联合编码点的有效个数以及SRI字段的比特长度按照等距编码的方式进行映射。In a possible implementation manner, the access network device may perform mapping in an equidistant coding manner according to the effective number of configured joint coding points and the bit length of the SRI field.
例如,可以采用如下公式进行映射。For example, the following formula can be used for mapping.
x+y=Mx+y=M
其中,N为配置的联合编码点的有效个数,M为SRI字段能够指示的编码点的个数,通过上市,可以获得x个步进为
的联合编码点,y个步进为
的联合编码点。
Among them, N is the valid number of configured joint code points, and M is the number of code points that can be indicated by the SRI field. Through listing, x steps can be obtained as The joint code point of , y steps are joint code point.
例如,参见表10,假设配置的联合编码点的有效个数为64,SRI字段的比特长度为4,即SRI字段能够指示的编码点的个数为16,则可以知道
x=6,y=10,那么16个联合编码点对应的取值分别是:0、2、4、6、8、10、13、16、19、22、25、28、31、34、37、40。
For example, referring to Table 10, assuming that the effective number of configured joint code points is 64, and the bit length of the SRI field is 4, that is, the number of code points that the SRI field can indicate is 16, then it can be known that x=6, y=10, then the values corresponding to the 16 joint coding points are: 0, 2, 4, 6, 8, 10, 13, 16, 19, 22, 25, 28, 31, 34, 37 , 40.
终端设备接收由联合编码获得的第一控制信息后,通过解码便可确定第二配置下的第一信道的传输。After receiving the first control information obtained through joint coding, the terminal device can determine the transmission of the first channel under the second configuration by decoding.
需要说明的是,以上仅是以SRI域进行举例,第一控制信息还可以包括其它字段,其确定的方式与之类似,为了简便,在此不再赘述。It should be noted that the above is only an example of the SRI field, and the first control information may also include other fields, which are determined in a similar manner, and are not repeated here for simplicity.

作为示例而非限定,为了清楚,以SRI域进行举例。As an example rather than a limitation, the SRI domain is used as an example for clarity.
方式5:Way 5:

若第一信道在MTRP模式下进行STRP操作,终端设备可以根据第一控制信息所指示的第一SRS资源集合与接入网设备#2进行第一信道的传输。If the STRP operation is performed on the first channel in the MTRP mode, the terminal device may perform transmission on the first channel with the access network device #2 according to the first SRS resource set indicated by the first control information.

可选地,该第一SRS资源集合为MTRP模式中的多个SRS资源集合中的索引最小的SRS资源集合。Optionally, the first SRS resource set is an SRS resource set with the smallest index among multiple SRS resource sets in the MTRP mode.
例如,参见图6,MTRP模式下包括第一接入网设备#1对应的SRS资源集合1和第二接入网设备#2对应的SRS资源集合2以及对应的信道的信息(例如图6所示的PUSCH#1和PUSCH#2),终端设备可以根据第一控制信息,与第一SRS资源集合(例如图6中的SRS资源集合1)相关联,该第一SRS资源集合与该第一控制信息的关联可以采用静态配 置、动态配置或者采用协议约束。在这种情况下,其它的指示信息,例如PUSCH#1的相应信息可以由第一控制信息中获得。For example, referring to FIG. 6 , in the MTRP mode, the SRS resource set 1 corresponding to the first access network device # 1 and the SRS resource set 2 corresponding to the second access network device #2 and the corresponding channel information (for example, as shown in FIG. 6 PUSCH # 1 and PUSCH #2 shown), the terminal device can associate with the first SRS resource set (for example, SRS resource set 1 in FIG. 6 ) according to the first control information, and the first SRS resource set is associated with the first The association of control information can adopt static configuration, dynamic configuration or protocol constraints. In this case, other indication information, such as corresponding information of PUSCH# 1, can be obtained from the first control information.
方式6:Method 6:

例如,参见图7,终端设备对第一控制信息进行解析,获得MTRP模式下的第三控制信息的监控信息。从而,终端设备可以根据监控信息进行监控,以获取MTRP模式下第一接入网设备#2和第二接入网设备#3对应的信道的信息(例如图7所示的PUSCH#1和PUSCH#2),从而确定第二配置下的第一信道的传输。For example, referring to FIG. 7 , the terminal device parses the first control information to obtain monitoring information of the third control information in MTRP mode. Therefore, the terminal device can monitor according to the monitoring information, so as to obtain the channel information corresponding to the first access network device #2 and the second access network device #3 in MTRP mode (for example, PUSCH # 1 and PUSCH # 1 shown in FIG. 7 #2), so as to determine the transmission of the first channel under the second configuration.
