方式一:将与类型1公共搜索空间(Type1 Common search space)在时域上发生重叠的随机接入时机确定为无效的随机接入资源。
Method 1: Determine random access opportunities that overlap with the Type 1 Common search space in the time domain as invalid random access resources.
在一种实现方式中,一个随机接入时机由一个独立可用于PRACH盲重传的资源组成,即一个随机接入时机对应于一个独立可用于PRACH盲重传的资源。In an implementation manner, a random access opportunity consists of a resource that can be independently used for PRACH blind retransmission, that is, a random access opportunity corresponds to a resource that can be independently used for PRACH blind retransmission.
在另一种实现方式中,一个随机接入时机由N个独立可用于PRACH盲重传的资源组成,其中,N为正整数。例如:N为2,4,8等。在此实现方式中,在任一用于PRACH盲重传的资源与类型1公共搜索空间在时域上发生重叠时,将所述用于PRACH盲重传的资源所属的随机接入时机确定为无效的随机接入资源。In another implementation manner, a random access opportunity consists of N resources that can be independently used for PRACH blind retransmission, where N is a positive integer. For example: N is 2, 4, 8, etc. In this implementation, when any resource used for PRACH blind retransmission overlaps with the type 1 public search space in the time domain, the random access opportunity to which the resource used for PRACH blind retransmission belongs is determined to be invalid. random access resources.
例如:一个随机接入时机由8个独立可用于PRACH盲重传的资源组成,其中第1个用于PRACH盲重传的资源与类型1公共搜索空间在时域上发生重叠,其它7个用于PRACH盲重传的资源均未与类型1公共搜索空间在时域上发生重叠,确定此随机接入时机为无效的随机接入时机。For example: a random access opportunity consists of 8 resources that can be independently used for PRACH blind retransmission. Among them, the first resource used for PRACH blind retransmission overlaps with the type 1 public search space in the time domain, and the other 7 resources are used for PRACH blind retransmission. None of the PRACH blind retransmission resources overlaps with the Type 1 public search space in the time domain, and this random access opportunity is determined to be an invalid random access opportunity.
一种可能的处理方式中,确定多个随机接入时机后,依次判断每个随机接入时机中是否存在重叠情况(即是否存在与类型1公共搜索空间在时域上发生重叠的用于PRACH盲重传的资源),将存在所述重叠情况的随机接入时机确定为无效的随机接入时机,将不存在所述重叠情况的随机接入时机确定为有效的随机接入时机。In one possible processing method, after determining multiple random access opportunities, it is determined whether there is overlap in each random access opportunity (that is, whether there is an overlap in the time domain with the type 1 public search space for PRACH). Blind retransmission resources), determine the random access opportunities with the overlapping situation as invalid random access opportunities, and determine the random access opportunities without the overlapping situation as valid random access opportunities.
方式二:当一个随机接入时机由N个独立可用于PRACH盲重传的有效资源组成时,所述有效资源通过下述方式确定:不将与类型1公共搜索空间在时域上发生重叠的PRACH资源确定为有效的随机接入资源。
Method 2: When a random access opportunity consists of N effective resources that can be independently used for PRACH blind retransmission, the effective resources are determined in the following way: the effective resources do not overlap with the type 1 public search space in the time domain. The PRACH resource is determined as a valid random access resource.
或者可以描述为:将与类型1公共搜索空间在时域上发生重叠的PRACH资源确定为无效资源,此无效资源不计入随机接入时机内,并且此无效资源不用于PRACH盲重传。Or it can be described as: PRACH resources that overlap with the type 1 public search space in the time domain are determined as invalid resources. This invalid resource is not included in the random access opportunity, and this invalid resource is not used for PRACH blind retransmission.
例如:PRACH盲重传的次数为N,则一个随机接入时机由N个PRACH重传资源组成。在确定随机接入时机(RO)时,先确定前N个PRACH重传资源中是否存在无效资源,如果存在无效资源,则不将无效资源计入RO,沿着PRACH重传资源的排列顺序向后顺延。For example: the number of PRACH blind retransmissions is N, then a random access opportunity consists of N PRACH retransmission resources. When determining the random access opportunity (RO), first determine whether there are invalid resources in the first N PRACH retransmission resources. If there are invalid resources, the invalid resources will not be included in the RO, and the order of the PRACH retransmission resources will be followed. Later postponed.
在一示例中,PRACH盲重传的次数为8,则一个随机接入时机由8个PRACH重传资源组成。在确定随机接入时机(RO)时,先确定前8个PRACH重传资源中是否存在无效资源,如果第2个PRACH重传资源为无效资源,则不将第2个PRACH重传资源计入RO, 如果第9个PRACH重传资源不是无效资源,则此RO包括第1个PRACH重传资源以及第3至9个PRACH重传资源;如果第9个PRACH重传资源不是无效资源,则不将第9个PRACH重传资源计入RO,继续判断第10个PRACH重传资源中是否存在无效的资源,以此类推。In an example, the number of PRACH blind retransmissions is 8, so one random access opportunity consists of 8 PRACH retransmission resources. When determining the random access opportunity (RO), first determine whether there are invalid resources in the first 8 PRACH retransmission resources. If the second PRACH retransmission resource is an invalid resource, the second PRACH retransmission resource will not be counted. RO, if the 9th PRACH retransmission resource is not an invalid resource, this RO includes the 1st PRACH retransmission resource and the 3rd to 9th PRACH retransmission resources; if the 9th PRACH retransmission resource is not an invalid resource, then no Count the 9th PRACH retransmission resource into RO, continue to determine whether there are invalid resources in the 10th PRACH retransmission resource, and so on.
其中,N的值可以基于任一下述方式确定:Among them, the value of N can be determined based on any of the following methods:
所述N为网络设备配置的PRACH重传次数;The N is the number of PRACH retransmissions configured by the network device;
所述N为协议规定的PRACH重传次数。The N is the number of PRACH retransmissions specified in the protocol.
方式三:将位于类型1公共搜索空间之后Ngap个符号后的并且与所述第二时域资源发生重叠的随机接入时机确定为无效的随机接入时机。
Method 3: Determine a random access opportunity located Ngap symbols after the Type 1 public search space and overlapping with the second time domain resource as an invalid random access opportunity.
其中,Ngap为TDD band下位于SSB/下行符号之后的有效的RO需要与所述SSB/下行符号之间间隔的符号个数。Among them, Ngap is the number of symbols between the effective RO required after the SSB/downlink symbol and the SSB/downlink symbol in the TDD band.
本方式三中沿用3GPP TS38.211中的TDD band对应的Ngap,可以提高对协议的兼容性。In this method three, the Ngap corresponding to the TDD band in 3GPP TS38.211 is used, which can improve the compatibility with the protocol.
在TS38.211中的表8.1-2中,随机接入前导子载波间隔(preamble SCS)与Ngap具有对应关系。如表1所示:In Table 8.1-2 in TS38.211, the random access preamble subcarrier spacing (preamble SCS) has a corresponding relationship with Ngap. As shown in Table 1:
表1Table 1
Preamble SCSPreamble SCS | NgapNgap |
1.25kHz或5kHz1.25kHz or 5kHz | 00 |
15kHz或30kHz或60kHz或120kHz15kHz or 30kHz or 60kHz or 120kHz | 22 |
方式四:将符合方式一和预设规则的随机接入时机确定为无效的随机接入资源。
Method 4: Determine random access opportunities that comply with Method 1 and preset rules as invalid random access resources.
其中,预设规则为R15或R16中基于TDD band确定有效RO的规则。具体包括:Among them, the default rule is the rule in R15 or R16 that determines the effective RO based on TDD band. Specifically include:
对于成对频谱或额外的上行链路频带,所有随机接入时机均是有效的。For paired spectrum or additional uplink bands, all random access opportunities are valid.
对于不成对频谱,如果UE未被提供tdd_UL_DL_ConfigurationCommon,PRACH时隙中的随机接入时机符合下述条件时为有效的:在未位于PRACH时隙中的一SS/PBCH块之前并且开始于上一SS/PBCH块重复符号之后的至少Ngap个符号处。如果UE被提供了tdd_UL_DL_ConfigurationCommon,PRACH时隙中的随机接入时机符合下述条件时为有效的:位于上行符号中,或者,在未位于PRACH时隙中的一SS/PBCH块之前并且开始于上一SS/PBCH块重复符号之后的至少Ngap个符号处。For unpaired spectrum, if the UE is not provided with tdd_UL_DL_ConfigurationCommon, the random access opportunity in the PRACH slot is valid when it meets the following conditions: before an SS/PBCH block not located in the PRACH slot and starting from the previous SS /PBCH block repeat symbol at least Ngap symbols after. If the UE is provided with tdd_UL_DL_ConfigurationCommon, the random access opportunity in the PRACH slot is valid when it meets the following conditions: located in the uplink symbol, or before and starting from an SS/PBCH block not located in the PRACH slot. An SS/PBCH block is repeated at least Ngap symbols after the symbol.
方式五:将符合方式二和所述预设规则的随机接入资源确定为无效的随机接入资源。
Method 5: Determine random access resources that comply with Method 2 and the preset rules as invalid random access resources.
在一些可能的实施方式中,为避免对legacy用户设备调度产生影响,所述用于PRACH盲重传的随机接入时机是独立配置的。In some possible implementations, in order to avoid affecting the scheduling of legacy user equipment, the random access timing for PRACH blind retransmission is configured independently.
在一些可能的实施方式中,不允许存在传统配置的RO(legacy RO)与独立配的RO(separate RO)位于相同的时域资源上,但是mapping到不同的SSB index上的配置。即,传统配置的RO(legacy RO)与独立配的RO(separate RO)位于相同的时域资源时,需映射到相同的SSB index上。In some possible implementations, configurations in which the legacy RO (legacy RO) and the independently configured RO (separate RO) are located on the same time domain resource but mapped to different SSB indexes are not allowed to exist. That is, when the traditionally configured RO (legacy RO) and the independently configured RO (separate RO) are located in the same time domain resource, they need to be mapped to the same SSB index.
