However, not every RACH resource has a random access (Random Access, RA) message sent. Since the network side does not know the actual occupancy of the RACH resources, in order to avoid interference to the RACH channel, all uplink resources cannot be used for uplink data transmission, resulting in waste of resources and reduced spectrum efficiency.

本公开涉及通信技术领域,尤其涉及一种信息传输方法、装置、电子设备及存储介质。The present disclosure relates to the field of communication technologies, and in particular, to an information transmission method, an apparatus, an electronic device, and a storage medium.
移动通信系统中,随着技术的演进和应用场景的需求,不同类型的终端/用户设备(User Equipment,UE)被陆续定义,例如,覆盖增强(Coverage Enhancement,CE)UE,能力降低能力降低(Reduced capability,RedCap)UE,小数据(small data)UE等。考虑到这些UE的应用场景、所采用的技术均不相同,UE类型的识别将是一个重要课题。In the mobile communication system, with the evolution of technology and the requirements of application scenarios, different types of terminals/user equipment (User Equipment, UE) are defined one after another, for example, Coverage Enhancement (CE) UE, capability reduction capability reduction ( Reduced capability, RedCap) UE, small data (small data) UE, etc. Considering that these UEs have different application scenarios and adopted technologies, identification of UE types will be an important topic.
已有的技术方案在初始接入过程中完成对不同UE类型的识别,例如,通过独立的随机接入信道(Random Access Channel,RACH)配置(configuration),或者通过不同的前导索引(Preamble index)区分不同类型的UE。The existing technical solutions complete the identification of different UE types in the initial access process, for example, through an independent random access channel (Random Access Channel, RACH) configuration (configuration), or through different preamble indexes (Preamble index) Different types of UEs are distinguished.
但是随着需要进行区分的UE类型的增多,配置独立的RACH configuration会极大的降低系统的传输效率,影响系统的性能。However, with the increase of UE types that need to be distinguished, configuring independent RACH configuration will greatly reduce the transmission efficiency of the system and affect the performance of the system.

在第五代新无线接入技术(5th Generation New RAT,5G NR)移动通信系统中,随着技术的演进和应用场景的需求,不同类型的终端被陆续定义。例如,第三代合作伙伴计划(The 3rd Generation Partnership Project,3GPP)Rel-17版本协议中定义了CE终端(Terminal,也称用户设备(User Equipment,UE)),RedCap终端,small data终端等。考虑到前述终端面对的应用场景、所采用的技术均不相同,终端类型的识别将是一个重要课题。In the 5th Generation New RAT (5G NR) mobile communication system, with the evolution of technology and the requirements of application scenarios, different types of terminals are defined one after another. For example, the 3rd Generation Partnership Project (3GPP) Rel-17 version protocol defines CE terminals (Terminal, also known as User Equipment (UE)), RedCap terminals, small data terminals, etc. Considering that the application scenarios and technologies used by the aforementioned terminals are all different, the identification of terminal types will be an important topic.
在Rel-17的讨论中,已经涉及针对终端类型的识别技术,典型的方法是在初始接入过程中完成对不同终端类型的识别。In the discussion of Rel-17, the identification technology for terminal types has been involved, and a typical method is to complete the identification of different terminal types in the initial access process.
例如,当前5G NR系统中,存在四步随机接入(4-step Random Access,4-step RA)和两步随机接入(2-step Random Access,2-step RA)。具有2-step RA能力的终端根据当前的信道状况,选择采用4-step RA或者2-step RA发起随机接入过程(random access procedure)。此时终端和基站通过两种途径区分4-step RA和2-step RA。For example, in the current 5G NR system, there are four-step random access (4-step Random Access, 4-step RA) and two-step random access (2-step Random Access, 2-step RA). A terminal with 2-step RA capability chooses to use 4-step RA or 2-step RA to initiate a random access procedure according to the current channel conditions. At this time, the terminal and the base station distinguish between 4-step RA and 2-step RA in two ways.
1、通过独立的RACH configuration,也即4-step RA和2-step RA占用不同的时频资源发送前导(Preamble)码。1. Through independent RACH configuration, that is, 4-step RA and 2-step RA occupy different time-frequency resources to send the preamble code.
2、通过不同的Preamble index区别不同类型的终端,也即4-step RA和2-step RA在相同的时频资源上发送不同的Preamble index。2. Different types of terminals are distinguished by different Preamble indexes, that is, 4-step RA and 2-step RA send different Preamble indexes on the same time-frequency resource.
RACH资源为周期性资源,是小区级别的配置,一旦配置下来在系统中就一直存在。但是并不是在每个RACH资源上都有随机接入(Random Access,RA)消息的发送。由于网络侧不知道RACH资源的实际占用情况,为了避免对RACH信道的干扰,所有的上行资源均不能用作上行数据的传输,从而造成资源的浪费,降低了频谱效率。RACH resources are periodic resources and are configured at the cell level. Once configured, they always exist in the system. However, not every RACH resource has a random access (Random Access, RA) message sent. Since the network side does not know the actual occupancy of the RACH resources, in order to avoid interference to the RACH channel, all uplink resources cannot be used for uplink data transmission, resulting in waste of resources and reduced spectrum efficiency.
另外,由于需要保证RACH的传输性能,基站在调度上行传输时需要避开RACH资源,当系统中存在过多的RACH资源时,将造 成终端上行传输资源的碎片化,使得调度过度复杂。In addition, due to the need to ensure the transmission performance of the RACH, the base station needs to avoid the RACH resources when scheduling uplink transmission. When there are too many RACH resources in the system, the uplink transmission resources of the terminal will be fragmented, making the scheduling excessively complicated.
本公开实施例针对上述技术问题,利用不同随机接入信道时机(RACH occasion,RO)区分不同类型的终端,不同类型的终端在不同的RO内进行随机接入前导码的发送,网络侧根据终端发送随机接入前导码所使用的RO确定终端的类型。In view of the above technical problems, the embodiments of the present disclosure use different random access channel occasions (RACH occasion, RO) to distinguish different types of terminals, and different types of terminals send random access preambles in different ROs. The RO used to send the random access preamble determines the type of terminal.
为使本公开实施例的目的、技术方案和优点更加清楚,下面将结合本公开实施例中的附图,对本公开实施例中的技术方案进行清楚、完整地描述,显然,所描述的实施例仅仅是本公开一部分实施例,而不是全部的实施例。基于本公开中的实施例,本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例,都属于本公开保护的范围。In order to make the purposes, technical solutions and advantages of the embodiments of the present disclosure clearer, the technical solutions in the embodiments of the present disclosure will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present disclosure. Obviously, the described embodiments These are only some of the embodiments of the present disclosure, but not all of the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present disclosure.
图1是本公开实施例提供的一种信息传输方法的流程示意图之一,如图1所示,本公开实施例提供的一种信息传输方法,其执行主体可以为终端。该方法包括:FIG. 1 is one of the schematic flow charts of an information transmission method provided by an embodiment of the present disclosure. As shown in FIG. 1 , an execution subject of an information transmission method provided by an embodiment of the present disclosure may be a terminal. The method includes:
步骤101、终端根据自身的类型以及随机接入信道时机RO与终端类型的关联关系,确定发送随机接入前导码的目标RO。Step 101: The terminal determines the target RO for sending the random access preamble according to its own type and the association between the random access channel opportunity RO and the terminal type.
具体来说,本公开实施例中,利用不同RO区分不同类型的终端,不同类型的终端在不同的RO内进行随机接入前导码的发送,网络侧根据终端发送随机接入前导码所使用的RO确定终端的类型。Specifically, in the embodiment of the present disclosure, different ROs are used to distinguish different types of terminals, and different types of terminals send random access preambles in different ROs. RO determines the type of terminal.
首先,终端需要确定RO与终端类型的关联关系。First, the terminal needs to determine the association relationship between the RO and the terminal type.
一方面,RO与终端类型的关联关系可以通过协议预先配置。On the one hand, the association relationship between the RO and the terminal type may be pre-configured through a protocol.
另一方面,RO与终端类型的关联关系可以由网络侧进行配置。On the other hand, the association relationship between the RO and the terminal type can be configured by the network side.
RO与终端类型的关联关系可以是终端的类型编号与终端被允许使用的RO所属的SSB2RO映射周期或SSB2RO关联时段的编号之间的对应关系。也可以是终端的比特图(bitmap)与终端被允许使用的RO所属的SSB2RO映射周期或SSB2RO关联时段的编号之间的对应关系等。The association relationship between the RO and the terminal type may be the corresponding relationship between the type number of the terminal and the SSB2RO mapping period or the number of the SSB2RO association period to which the RO that the terminal is allowed to use belongs. It may also be the correspondence between the bitmap of the terminal and the SSB2RO mapping period to which the RO that the terminal is allowed to use belongs, or the number of the SSB2RO associated period, or the like.
例如,RO与终端类型的关联关系如下:For example, the relationship between RO and terminal type is as follows:
第1类终端被允许使用的RO的编号为1,第2类终端被允许使用的RO的编号为2,…,第n类终端被允许使用的RO的编号为n。The number of ROs allowed to be used by the terminal of type 1 is 1, the number of ROs allowed to be used by terminals of type 2 is 2, ..., and the number of ROs allowed to be used by terminals of type n is n.
再例如,RO与终端类型的关联关系如下:For another example, the relationship between RO and terminal type is as follows:
第1类终端被允许使用的RO所属的同步信号块到随机接入信道时机(synchronization signal block to RACH occasion,SSB2RO/SSB-to-RO)映射周期(mapping cycle)的编号为1,第2类终端被允许使用的RO所属的SSB2RO mapping cycle的编号为2,…,第n类终端被允许使用的RO所属的SSB2RO mapping cycle的编号为n。The synchronization signal block to random access channel (synchronization signal block to RACH occasion, SSB2RO/SSB-to-RO) mapping cycle to which the RO that type 1 terminals are allowed to use is numbered 1, and type 2 The number of the SSB2RO mapping cycle to which the RO that the terminal is allowed to use is 2, ..., and the number of the SSB2RO mapping cycle to which the RO that the nth type of terminal is allowed to use belongs is n.

其中,m为终端的类型编号/识别码;M为需要区分的终端的种类数;n
cycle为第m类终端被允许使用的RO所属的SSB2RO映射周期或SSB2RO关联时段的编号/识别码,n为自然数。
Among them, m is the type number/identification code of the terminal; M is the number of types of terminals that need to be distinguished; n cycle is the SSB2RO mapping cycle or the number/identification code of the SSB2RO association period to which the mth type of terminal is allowed to use the RO, and n is a natural number.

终端确定RO与终端类型的关联关系之后,若需要进行随机接入,则根据自身的类型以及RO与终端类型的关联关系,确定发送随机接入前导码的目标RO。After the terminal determines the association relationship between the RO and the terminal type, if random access is required, it determines the target RO for sending the random access preamble according to its own type and the association relationship between the RO and the terminal type.
例如,RO与终端类型的关联关系为:C个association period里的N1个SSB-to-RO mapping cycle用于CE UE的随机接入;N2个SSB-to-RO mapping cycle用于RedCap UE的随机接入;N3个 SSB-to-RO mapping cycle用于small data的随机接入,并以此类推。不同类型的终端在对应的SSB-to-RO mapping cycle所包含的RO上发送Preamble码。For example, the association relationship between RO and terminal type is: N1 SSB-to-RO mapping cycles in C association periods are used for random access of CE UEs; N2 SSB-to-RO mapping cycles are used for random access of RedCap UEs Access; N3 SSB-to-RO mapping cycles are used for random access of small data, and so on. Different types of terminals send the Preamble code on the RO included in the corresponding SSB-to-RO mapping cycle.
其中,N1个SSB-to-RO mapping cycle、N2个SSB-to-RO mapping cycle、N3个SSB-to-RO mapping cycle互不重叠。N1+N2+N3+…+Nn<=C个association period内包含的cycle总和,C,N1,N2,N3…Nn均为大于等于1的整数。Among them, N1 SSB-to-RO mapping cycles, N2 SSB-to-RO mapping cycles, and N3 SSB-to-RO mapping cycles do not overlap each other. N1+N2+N3+...+Nn<=sum of cycles included in C association periods, C, N1, N2, N3...Nn are all integers greater than or equal to 1.

When performing random access, the RedCap UE uses the RO included in the N2 SSB-to-RO mapping cycles to send the Preamble code. When the small data UE performs random access, it uses the RO included in the N3 SSB-to-RO mapping cycles to send the Preamble code.

例如,RO与终端类型的关联关系如下:For example, the relationship between RO and terminal type is as follows:
CE UE被允许使用的RO所属的SSB2RO association period的编号为1;RedCap UE被允许使用的RO所属的SSB2RO association period的编号为2;small data UE被允许使用的RO所属的SSB2RO association period的编号为3。The number of the SSB2RO association period to which the RO that the CE UE is allowed to use is 1; the number of the SSB2RO association period to which the RO that the RedCap UE is allowed to use is 2; the number of the SSB2RO association period to which the RO that the small data UE is allowed to use is 3.
则基站在接收到终端在编号为1的SSB2RO association period包含的RO上发送的随机接入Preamble码之后,确定该终端的类型为CE UE;基站在接收到终端在编号为2的SSB2RO association period 包含的RO上发送的随机接入Preamble码之后,确定该终端的类型为RedCap UE;基站在接收到终端在编号为3的SSB2RO association period包含的RO上发送的随机接入Preamble码之后,确定该终端的类型为small data UE。Then the base station determines that the type of the terminal is CE UE after receiving the random access Preamble code sent by the terminal on the RO included in the SSB2RO association period numbered 1; After the random access Preamble code sent on the RO, determine that the type of the terminal is RedCap UE; after receiving the random access Preamble code sent by the terminal on the RO included in the SSB2RO association period numbered 3, the base station determines that the terminal The type is small data UE.

The RO in the mapping period of the SSB2RO numbered 2 in the period sends a random access Preamble code, and the terminal with type number 3 uses the RO in the mapping period of the SSB2RO numbered 3 in the SSB2RO association period numbered 1 to send random access Access the Preamble code.
需要说明的是:上述举例并非穷举,只要能保证不同终端所使用的RO所属的SSB2RO的映射周期不重叠,通过RO所属的SSB2RO的映射周期的编号能够区分不同的终端的其他配置方式均可行,此处不再赘述。It should be noted that the above examples are not exhaustive, as long as it can ensure that the mapping periods of the SSB2ROs to which the ROs used by different terminals do not overlap, and the number of the mapping periods of the SSB2ROs to which the ROs belong can be used to distinguish different terminals.

例如,RO与终端类型的关联关系如下:For example, the relationship between RO and terminal type is as follows:
类型编号为1的终端被允许使用的RO所属的SSB2RO关联时段(association period)的编号为1,类型编号为2的终端被允许使用的RO所属的SSB2RO association period的编号为2,…,类型编号为n的终端被允许使用的RO所属的SSB2RO association period的编号为n。The number of the SSB2RO association period (association period) to which the terminal with type number 1 is allowed to use is 1, and the number of the SSB2RO association period to which the terminal with type number 2 is allowed to use is 2, ..., type number The number of the SSB2RO association period to which the terminal n is allowed to use belongs is n.
本公开实施例提供的信息传输方法,终端的类型编号与终端被允许使用的RO所属的SSB2RO映射周期或SSB2RO关联时段的编号相对应,不同的类型编号对应的SSB2RO映射周期或SSB2RO关联时段的编号不同,从而区分出不同类型的终端,避免了资源的碎片化,提高了资源的利用率。In the information transmission method provided by the embodiment of the present disclosure, the type number of the terminal corresponds to the number of the SSB2RO mapping period or the SSB2RO association period to which the RO that the terminal is allowed to use belongs, and the number of the SSB2RO mapping period or the SSB2RO association period corresponding to different type numbers Therefore, different types of terminals are distinguished, the fragmentation of resources is avoided, and the utilization rate of resources is improved.

本公开实施例提供的信息传输方法,将终端的类型编号与终端被允许使用的RO所属的SSB2RO映射周期或SSB2RO关联时段的编号的模值建立对应关系,从而区分出不同类型的终端,避免了资源的碎片化,提高了资源的利用率。The information transmission method provided by the embodiment of the present disclosure establishes a corresponding relationship between the type number of the terminal and the modulo value of the SSB2RO mapping period or the number of the SSB2RO association period to which the RO that the terminal is allowed to use belongs, thereby distinguishing different types of terminals, avoiding the need for The fragmentation of resources improves the utilization of resources.
下面以几个具体的例子对上述实施例中的方法进行一步说明:The method in the above-mentioned embodiment is described in one step with several specific examples below:
例1:example 1:
5G系统在Rel-17以及后续版本中引入了多种类型的终端,这些终端适用于不同的应用场景,并有对应的能力和支撑技术,需要尽早进行区分以便实现最优的性能。假设目前系统中存在三种新类型的终端需要在random access procedure中予以区分,分别为:CE UE,RedCap UE和small data UE。网络侧为这三种不同类型的终端配置相同的RACH configuration,并通过该RACH configuration确定的RO中的部分RO来确定终端的类型。The 5G system introduces various types of terminals in Rel-17 and subsequent versions. These terminals are suitable for different application scenarios and have corresponding capabilities and supporting technologies. They need to be distinguished as soon as possible to achieve optimal performance. It is assumed that there are three new types of terminals in the current system that need to be distinguished in the random access procedure, namely: CE UE, RedCap UE and small data UE. The network side configures the same RACH configuration for these three different types of terminals, and determines the type of the terminal by using some ROs in the ROs determined by the RACH configuration.
假设网络侧通过为不同类型的终端配置特定RO的方式,在RO资源上区分终端的具体类型。It is assumed that the network side distinguishes specific types of terminals on RO resources by configuring specific ROs for different types of terminals.
假设当前系统为FDD,频段为FR1,基站为三种不同类型的终端配置的RACH资源编号为RACH configuration#27(具体的参数配置以及含意可见参考文件TS38.211,Table 6.3.3.2-2)。假设当前系统中的同步信号块候选(SSB candidate)的个数为8。则根据SIB1中携带的参数ssb-perRACH-OccasionAndCB-PreamblesPerSSB,可知SSB、RO以及preamble码的映射关系,假设每个RO与一个SSB映射,每个SSB与8个preamble码映射。基于此配置,此时SSB-to-RO association period大小为10个slot。假设SCS=15kHz,因此SSB-to-RO association period为10ms。Assuming that the current system is FDD, the frequency band is FR1, and the RACH resource number configured by the base station for three different types of terminals is RACH configuration#27 (for the specific parameter configuration and meaning, please refer to the reference document TS38.211, Table 6.3.3.2-2). It is assumed that the number of synchronization signal block candidates (SSB candidates) in the current system is 8. Then according to the parameter ssb-perRACH-OccasionAndCB-PreamblesPerSSB carried in SIB1, the mapping relationship between SSB, RO and preamble code can be known. It is assumed that each RO is mapped to one SSB, and each SSB is mapped to 8 preamble codes. Based on this configuration, the size of the SSB-to-RO association period is 10 slots at this time. Suppose SCS=15kHz, so the SSB-to-RO association period is 10ms.
基于上述配置,在一个association period内可用于RACH传输和不可用于RACH传输的RO的示意图如图2所示。Based on the above configuration, a schematic diagram of ROs that can be used for RACH transmission and cannot be used for RACH transmission within an association period is shown in FIG. 2 .
基站在SIB1中额外发送不同类型终端对应RO的配置信息,包括:The base station additionally sends configuration information of ROs corresponding to different types of terminals in SIB1, including:
1)用于终端类型识别的时间窗口包含的SSB-to-RO association period或者SSB-to-RO mapping cycle的数量。1) The number of SSB-to-RO association period or SSB-to-RO mapping cycle included in the time window for terminal type identification.
2)指示C个association period里的N1个SSB-to-RO mapping cycle用于类型1终端的随机接入;N2个SSB-to-RO mapping cycle用于类型2终端的随机接入;N3个SSB-to-RO mapping cycle用于类型3终端的随机接入,并以此类推。不同类型的终端在对应的RO上发送Preamble码。2) Indicate N1 SSB-to-RO mapping cycles in C association periods for random access of type 1 terminals; N2 SSB-to-RO mapping cycles for random access of type 2 terminals; N3 SSBs -to-RO mapping cycle is used for random access of type 3 terminals, and so on. Different types of terminals send the Preamble code on the corresponding RO.
其中,N1个cycle、N2个cycle、N3个cycle互不重叠。N1+N2+N3+…<=C个association period内包含的cycle总和。C,N1,N2,N3…为大于等于1的整数。Among them, N1 cycles, N2 cycles, and N3 cycles do not overlap with each other. N1+N2+N3+...<=sum of cycles included in C association periods. C, N1, N2, N3... are integers greater than or equal to 1.
假设C=3,N1=1,N2=1,N3=1,即CE UE对应第一个SSB-to-RO mapping cycle,RedCap UE对应第二个SSB-to-RO mapping cycle,small data UE对应第三个SSB-to-RO mapping cycle。根据该信息,则确定图2中第一个SSB-to-RO mapping cycle内包含的所有RO用于CE UE,第二个SSB-to-RO mapping cycle内包含的所有RO用于RedCap UE,第三个SSB-to-RO mapping cycle内包含的所有RO用于small data UE。也即CE UE只能在第一个SSB-to-RO mapping cycle内包含的任意RO中发送对应的preamble码,RedCap UE只能在第二个SSB-to-RO mapping cycle内包含的任意RO中发送对应的preamble码,small data UE只能在第三个SSB-to-RO mapping cycle内包含的任意RO中发送对应的preamble码。Assuming C=3, N1=1, N2=1, N3=1, that is, CE UE corresponds to the first SSB-to-RO mapping cycle, RedCap UE corresponds to the second SSB-to-RO mapping cycle, and small data UE corresponds to The third SSB-to-RO mapping cycle. According to this information, it is determined that all ROs included in the first SSB-to-RO mapping cycle in Figure 2 are used for CE UEs, and all ROs included in the second SSB-to-RO mapping cycle are used for RedCap UEs. All ROs included in the three SSB-to-RO mapping cycles are used for small data UEs. That is, the CE UE can only send the corresponding preamble code in any RO contained in the first SSB-to-RO mapping cycle, and the RedCap UE can only send the corresponding preamble code in any RO contained in the second SSB-to-RO mapping cycle. Send the corresponding preamble code, the small data UE can only send the corresponding preamble code in any RO included in the third SSB-to-RO mapping cycle.
对应地,网络侧如果在第一个SSB-to-RO mapping cycle内包含 的任意RO中检测接收到preamble码,则确定该终端为CE UE;如果在第二个SSB-to-RO mapping cycle内包含的任意RO中检测接收到preamble码,则确定该终端为RedCap UE;如果在第三个SSB-to-RO mapping cycle内包含的任意RO中检测接收到preamble码,则确定该终端为RedCap UE。Correspondingly, if the network side detects and receives a preamble code in any RO included in the first SSB-to-RO mapping cycle, it determines that the terminal is a CE UE; if it is in the second SSB-to-RO mapping cycle If the preamble code is detected in any RO included, it is determined that the terminal is a RedCap UE; if the preamble code is detected and received in any RO included in the third SSB-to-RO mapping cycle, it is determined that the terminal is a RedCap UE .
例2:Example 2:
基站在为不同类型终端配置对应的RO数目{N1,N2,N3…}时,可通过bitmap的方式对不同类型的终端进行配置。也即不同类型终端根据各自的bitmap确定C个association period内的哪些RO用于自身的preamble传输。When configuring the corresponding RO numbers {N1, N2, N3...} for different types of terminals, the base station may configure different types of terminals by means of a bitmap. That is, different types of terminals determine which ROs within the C association periods are used for their own preamble transmission according to their respective bitmaps.
每种类型的终端根据长度为3比特的bitmap确定自身对应的RO,bitmap中的1表示所述RO可用,0表示所述RO不可用。Each type of terminal determines its corresponding RO according to a bitmap with a length of 3 bits. 1 in the bitmap indicates that the RO is available, and 0 indicates that the RO is unavailable.
假设CE UE,RedCap UE以及small data UE对应的bitmap分别为{100}、{010}以及{001},则三种类型的终端对应的SSB-to-RO mapping cycle为:CE UE对应第一个SSB-to-RO mapping cycle,RedCap UE对应第二个SSB-to-RO mapping cycle,small data UE对应第三个SSB-to-RO mapping cycle。Assuming that the bitmaps corresponding to CE UE, RedCap UE and small data UE are {100}, {010} and {001} respectively, then the SSB-to-RO mapping cycle corresponding to the three types of terminals is: CE UE corresponds to the first SSB-to-RO mapping cycle, RedCap UE corresponds to the second SSB-to-RO mapping cycle, small data UE corresponds to the third SSB-to-RO mapping cycle.
终端发送preamble码以及基站检测接收preamble码的方法可参照例1,此处不再赘述。For the methods for the terminal to send the preamble code and the base station to detect and receive the preamble code, reference may be made to Example 1, which will not be repeated here.
例3:Example 3:
一个RO可对应多个SSB,也即一个SSB-to-RO association period内可包含多个SSB-to-RO mapping cycle。One RO can correspond to multiple SSBs, that is, one SSB-to-RO association period can contain multiple SSB-to-RO mapping cycles.
不同类型终端对应RO的配置信息可以通过协议预先配置,也可以参照例1或例2,此处不再赘述。The configuration information of the ROs corresponding to different types of terminals may be pre-configured through a protocol, or refer to Example 1 or Example 2, which will not be repeated here.
终端发送preamble码以及基站检测接收preamble码的方法可参照例1,此处不再赘述。For the methods for the terminal to send the preamble code and the base station to detect and receive the preamble code, reference may be made to Example 1, which will not be repeated here.
例4:Example 4:
本例子中,利用MIB中的1比特保留位确定当前C个关联周期 (association period)内配置的SSB-to-RO mapping cycle或者association period是否有部分用于不同类型UE的识别(identification)。In this example, a 1-bit reserved bit in the MIB is used to determine whether part of the SSB-to-RO mapping cycle or association period configured in the current C association periods (association periods) is used for identification of different types of UEs.
该1比特保留位的值为0表示不支持通过SSB-to-RO mapping cycle或者association period进行不同类型UE的识别。The value of this 1-bit reserved bit is 0, indicating that the identification of different types of UEs through the SSB-to-RO mapping cycle or association period is not supported.
该1比特保留位的值为1表示支持通过SSB-to-RO mapping cycle或者association period进行不同类型UE的识别。The value of the 1-bit reserved bit is 1 to support the identification of different types of UEs through the SSB-to-RO mapping cycle or association period.
可以通过协议预定义的方式确定哪些SSB-to-RO mapping cycle或者association period用于不同类型终端的识别。Which SSB-to-RO mapping cycle or association period is used for identification of different types of terminals can be determined in a pre-defined manner in the protocol.
例如,通过协议定义,从SFN#0开始,mod(n
cycle,M)=0的SSB-to-RO mapping cycle或者association period包含的RO用于第一类型的终端,mod(n
cycle,M)=1的SSB-to-RO mapping cycle或者association period包含的RO用于第二类型的终端,mod(n
cycle,M)=2的SSB-to-RO mapping cycle或者association period包含的RO用于第三类型的终端,并以此类推。
For example, according to the protocol definition, starting from SFN # 0, the SSB-to-RO mapping cycle with mod(n cycle ,M)=0 or the RO included in the association period is used for the first type of terminal, mod(n cycle ,M) The RO included in the SSB-to-RO mapping cycle or the association period of =1 is used for the second type of terminal, and the RO included in the SSB-to-RO mapping cycle or association period with mod(n cycle ,M)=2 is used for the second type of terminal. Three types of terminals, and so on.
其中,n
cycle为SSB-to-RO mapping cycle或者SSB-to-RO association period的编号。M为预定义的用于终端类型识别的SSB-to-RO mapping cycle或者SSB-to-RO association period窗口所包含的SSB-to-RO mapping cycle或者SSB-to-RO association period个数,不同类型的终端对应不同的SSB-to-RO mapping cycle或者SSB-to-RO association period,M也可以理解为需要区分的终端的种类数。
Among them, n cycle is the number of SSB-to-RO mapping cycle or SSB-to-RO association period. M is the number of SSB-to-RO mapping cycles or SSB-to-RO association periods included in the predefined SSB-to-RO mapping cycle or SSB-to-RO association period window for terminal type identification, different types The terminals correspond to different SSB-to-RO mapping cycles or SSB-to-RO association periods, and M can also be understood as the number of types of terminals that need to be distinguished.
某种类型的终端只能在该类型终端对应的RO上发送preamble码。网络侧一旦检测接收到preamble码,根据RO对应的终端类型确定发送preamble码的终端的具体类型,并根据终端类型进行相应的操作。A terminal of a certain type can only send the preamble code on the RO corresponding to the terminal of this type. Once the network side detects and receives the preamble code, it determines the specific type of the terminal sending the preamble code according to the terminal type corresponding to the RO, and performs corresponding operations according to the terminal type.
例5:Example 5:
在本例中,通过PBCH中的2比特保留位确定当前C个关联周期(association period)内配置的SSB-to-RO mapping cycle或者 association period,是否有部分用于不同类型UE的identification,并在对应的RO上发送preamble码。In this example, the 2-bit reserved bits in the PBCH are used to determine whether the SSB-to-RO mapping cycle or association period configured in the current C association periods (association periods) is partially used for identification of different types of UEs. The preamble code is sent on the corresponding RO.
PBCH中的2比特保留位的值为00表征不允许终端通过SSB2RO映射周期或SSB2RO关联时段区分不同终端的类型;The value of the 2-bit reserved bits in the PBCH is 00, indicating that the terminal is not allowed to distinguish the types of different terminals through the SSB2RO mapping period or the SSB2RO association period;

第一集合、第二集合和第三集合中包含的终端类型可以根据具体情况进行配置。配置方式可以为基站配置,也可以为协议预先配置。The terminal types included in the first set, the second set and the third set can be configured according to specific conditions. The configuration mode can be configured by the base station or pre-configured by the protocol.
