Description

一种上行接入共享方法和设备Uplink access sharing method and device

技术领域Technical Field

本申请涉及移动通信技术领域,尤其涉及一种上行接入共享方法、配置信令和设备。The present application relates to the field of mobile communication technology, and in particular to an uplink access sharing method, configuration signaling and device.

背景技术Background Art

在小区中同时存在中继设备和终端设备的时候,,二者都需要接入基站。如果配置相同的随机接入资源,使得随机接入参数的配置受到限制。举例来说,由于中继设备的功率和能力较高,当其位于主基站小区半径外的情况下,需要尝试接入到主基站上,那么主基站给终端配置随机接入参数的时候就会和中继设备进行匹配,发送的preamble格式中的GP和CP会很大,来满足中继设备的接入,或者是循环移位的数值很大,从而降低了可用循环移位的数量,这样对处于小区半径以内的终端接入是不合理的。但是,如果网络给中继设备和终端设备配置独立的随机接入资源,会大大增加信令开销,而且不利于随机接入资源的共享,影响接入的容量。When there are both relay devices and terminal devices in a cell, both need to access the base station. If the same random access resources are configured, the configuration of random access parameters is restricted. For example, due to the high power and capability of the relay device, when it is outside the cell radius of the main base station, it needs to try to access the main base station. Then when the main base station configures random access parameters for the terminal, it will match the relay device, and the GP and CP in the sent preamble format will be large to meet the access of the relay device, or the cyclic shift value will be large, thereby reducing the number of available cyclic shifts. This is unreasonable for terminal access within the cell radius. However, if the network configures independent random access resources for relay devices and terminal devices, it will greatly increase the signaling overhead, and is not conducive to the sharing of random access resources, affecting the access capacity.

具体实施方式DETAILED DESCRIPTION

为使本申请的目的、技术方案和优点更加清楚,下面将结合本申请具体实施例及相应的附图对本申请技术方案进行清楚、完整地描述。显然,所描述的实施例仅是本申请一部分实施例,而不是全部的实施例。基于本申请中的实施例,本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例,都属于本申请保护的范围。In order to make the purpose, technical solution and advantages of the present application clearer, the technical solution of the present application will be clearly and completely described below in combination with the specific embodiments of the present application and the corresponding drawings. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

以下结合附图,详细说明本申请各实施例提供的技术方案。The technical solutions provided by various embodiments of the present application are described in detail below in conjunction with the accompanying drawings.

图1为包含中继设备和终端设备的小区示意图。小区中同时存在中继设备61和终端设备62,二者都能接入到基站60。中继设备和终端设备各自发送随机接入序列,基站设备识别后发出随机接入相应。Figure 1 is a schematic diagram of a cell including a relay device and a terminal device. A relay device 61 and a terminal device 62 exist in the cell at the same time, and both can access a base station 60. The relay device and the terminal device each send a random access sequence, and the base station device sends a random access response after identifying it.

随机接入序列xu,v(n)的生成公式如下,其中基础序列为xu(i),Cv是循环移位,LRA是序列的长度。The generation formula of the random access sequence x u,v (n) is as follows, where the base sequence is x u (i), C v is the cyclic shift, and L RA is the length of the sequence.

xu,v(n)=xu((n+Cv)modLRA)x u,v (n)=x u ((n+C v )modL RA )

Figure GDA0004141951960000031
Figure GDA0004141951960000031

当LRA长度为139,循环移位的步长值Ncs=10的时候,循环移位的个数v为139/10下取整为13,而Cv的数值为0,10,20,…,120,用一个根序列,生成13个随机接入序列。要生成64个随机接入序列,共需要5个根序列。When the LRA length is 139 and the cyclic shift step value Ncs = 10, the number of cyclic shifts v is 139/10 rounded down to 13, and the value of Cv is 0, 10, 20, ..., 120. One root sequence is used to generate 13 random access sequences. To generate 64 random access sequences, a total of 5 root sequences are required.

需要说明,选用循环移位的数值和小区半径有关,假设有两个终端,UE1在小区的边缘,UE2距离eNB较近,UE1使用循环移位值为0,UE2使用循环移位值为Ncs。从eNB角度看来,由于传输时延的存在,UE1的循环移位值不是0而是其他的值X,只要值X小于Ncs,X与Ncs自相关的值为0,这样eNB将能区分接入过程中的UE1和UE2,这是ZC序列的特性。所以,小区最大覆盖半径受循环移位数值限制。It should be noted that the selected cyclic shift value is related to the cell radius. Assume that there are two terminals, UE1 is at the edge of the cell, and UE2 is closer to the eNB. UE1 uses a cyclic shift value of 0, and UE2 uses a cyclic shift value of N cs . From the perspective of the eNB, due to the existence of transmission delay, the cyclic shift value of UE1 is not 0 but other values X. As long as the value X is less than Ncs, the value of the autocorrelation between X and N cs is 0, so that the eNB will be able to distinguish UE1 and UE2 during the access process. This is the characteristic of the ZC sequence. Therefore, the maximum coverage radius of the cell is limited by the cyclic shift value.

图2为本发明上行接入信道共享方法的实施例流程图。FIG. 2 is a flow chart of an embodiment of the uplink access channel sharing method of the present invention.

步骤10、发送上行接入配置信令,所述配置信令包含用于指示第一步长值和或第二步长值的标识。所述第二步长值大于所述第一步长值。Step 10: Send an uplink access configuration signaling, wherein the configuration signaling includes an identifier for indicating the first step length value and/or a second step length value. The second step length value is greater than the first step length value.

当所述上行接入配置信令发送到所述终端设备时,至少包含第一步长值;当所述上行接入配置信令发送到中继设备时,至少包含第二步长值。When the uplink access configuration signaling is sent to the terminal device, it at least includes the first step length value; when the uplink access configuration signaling is sent to the relay device, it at least includes the second step length value.

考虑到中继设备的接入半径要大于终端设备的接入半径,当终端和中继配置相同资源的时候,对于相同的ZC根序列,可用定义两个循环移位步长值Ncs,小的Ncs用于终端设备接入,大的Ncs用于中继设备接入。Considering that the access radius of the relay device is larger than that of the terminal device, when the terminal and the relay are configured with the same resources, for the same ZC root sequence, two cyclic shift step values N cs can be defined. The small N cs is used for terminal device access, and the large N cs is used for relay device access.

现有技术是通过高层配置参数(zeroCorrelationZoneConfig)来获得循环移位的步长。为支持中继和终端不同的循环移位步长,引入两个高层配置参数,一个用于终端的配置参数(zeroCorrelationZoneConfig_UE),即第一步长值的标识,用于获得相对较小的循环移位步长值,另一个用于中继的配置参数(zeroCorrelationZoneConfig_IAB),即第二步长值的标识,获得相对较大的循环移位步长值。The prior art obtains the cyclic shift step size through a high-level configuration parameter (zeroCorrelationZoneConfig). To support different cyclic shift step sizes for relays and terminals, two high-level configuration parameters are introduced, one for the terminal configuration parameter (zeroCorrelationZoneConfig_UE), i.e., the identifier of the first step size value, used to obtain a relatively small cyclic shift step size value, and the other for the relay configuration parameter (zeroCorrelationZoneConfig_IAB), i.e., the identifier of the second step size value, used to obtain a relatively large cyclic shift step size value.

以下表举例来说,用于终端设备的第一步长值标识(zeroCorrelationZoneConfig_UE)的数值设置范围为0~10,对应的,第一步长值为表中第0~10行的NCS数值;用于中继设备的第二步长值标识(zeroCorrelationZoneConfig_IAB)的数值设置范围为11~15,第二步长值为表中第11~15行的Ncs数值;这样就保证了终端设备的循环移位较小,中继设备的循环移位较大。Taking the following table as an example, the value setting range of the first step length value identifier (zeroCorrelationZoneConfig_UE) used for the terminal device is 0 to 10, and the corresponding first step length value is the N CS value in rows 0 to 10 in the table; the value setting range of the second step length value identifier (zeroCorrelationZoneConfig_IAB) used for the relay device is 11 to 15, and the second step length value is the N cs value in rows 11 to 15 in the table; this ensures that the cyclic shift of the terminal device is smaller and the cyclic shift of the relay device is larger.

(上表数值仅作为举例,具体参数摘自3GPP标准38.211中“Table 6.3.3.1-7:Ncsfor preamble formats withΔfRA=15·2μkHz whereμ∈{0,1,2,3}”)(The values in the above table are only for example. The specific parameters are taken from "Table 6.3.3.1-7: N cs for preamble formats with Δf RA =15·2 μ kHz where μ∈{0,1,2,3}" in 3GPP standard 38.211)

步骤20、接收配置信令,用所述第一步长值或第二步长值对至少一个根序列循环移位,得到随机接入序列。Step 20: Receive configuration signaling, and cyclically shift at least one root sequence using the first step value or the second step value to obtain a random access sequence.

现有的机制是高层配置参数来获得生成随机接入序列的根序列和步长值,直到一共生成了64个随机接入序列为止。例如,用一个根序列生成13个随机接入序列。要生成64个随机接入序列,共需要5个根序列。The existing mechanism is to obtain the root sequence and step value for generating random access sequences by configuring parameters at a high level until a total of 64 random access sequences are generated. For example, 13 random access sequences are generated using one root sequence. To generate 64 random access sequences, a total of 5 root sequences are required.

例如,所述中继设备接收配置信令,所述配置信令中包含用于指示所述第二步长值的标识;用所述第二步长值对至少一个根序列循环移位,得到所述第二随机接入序列;将全部或部分的所述第二随机接入序列确定为所述第二随机接入序列的集合。For example, the relay device receives configuration signaling, wherein the configuration signaling includes an identifier for indicating the second step value; cyclically shifts at least one root sequence using the second step value to obtain the second random access sequence; and determines all or part of the second random access sequence as a set of the second random access sequences.

再例如,终端设备接收配置信令,所述配置信令包含用于指示所述第一步长值的标识;用所述第一步长值对所述至少一个根序列循环移位,得到所述第一机接入序列;在全部所述第一随机接入序列中排除与所述第二随机接入序列相同的部分,确定为所述第一随机接入序列的集合。For another example, a terminal device receives configuration signaling, wherein the configuration signaling includes an identifier for indicating the first step length value; cyclically shifts the at least one root sequence using the first step length value to obtain the first machine access sequence; and excludes the part that is identical to the second random access sequence in all the first random access sequences to determine the set of the first random access sequences.

用于终端设备的随机接入序列,属于第一随机接入序列的集合;用于中继设备的随机接入序列,属于第二随机接入序列的集合。The random access sequence used for the terminal device belongs to the set of first random access sequences; the random access sequence used for the relay device belongs to the set of second random access sequences.

步骤30、发送所述随机接入序列,所述随机接入序列属于所述第一随机接入序列的集合或所述第二随机接入序列的集合;Step 30: Send the random access sequence, where the random access sequence belongs to a set of the first random access sequences or a set of the second random access sequences;

终端设备发送的随机接入序列,为所述第一随机接入序列,是由至少一个根序列在第一步长值条件下通过循环移位生成的。The random access sequence sent by the terminal device is the first random access sequence, which is generated by cyclic shifting of at least one root sequence under the first step length value condition.

中继设备发送的随机接入序列,为所述第二随机接入序列,是由所述至少一个根序列在第二步长值条件下循环移位生成的。The random access sequence sent by the relay device is the second random access sequence, which is generated by cyclically shifting the at least one root sequence under the second step value condition.

步骤40、接收所述随机接入序列,判断所述随机接入序列属于所述第一随机接入序列的集合或第二随机接入序列的集合;Step 40: Receive the random access sequence, and determine whether the random access sequence belongs to the set of the first random access sequences or the set of the second random access sequences;

图3为第二步长是第一步长的倍数时随机接入序列的集合示意图。FIG3 is a schematic diagram of a set of random access sequences when the second step length is a multiple of the first step length.

作为本发明优化的实施例,所述第二步长值是所述第一步长值的倍数。在所述第一随机接入序列的集合中,排除与所述第二随机接入序列的集合中任意一个相同的第一随机接入序列。所述第一随机序列集合和第二随机序列集合中包含的随机序列总数为64个。As an optimized embodiment of the present invention, the second step value is a multiple of the first step value. In the set of the first random access sequences, a first random access sequence that is identical to any one in the set of the second random access sequences is excluded. The total number of random sequences included in the first random sequence set and the second random sequence set is 64.

为支持中继设备和终端设备不同的循环移位,基站侧根据所覆盖的中继设备的覆盖范围,配置中继设备的循环移位步长是终端设备循环移位的倍数N(N为正整数),以保证中继设备使用比终端N倍大的循环移位步长来生成随机接入序列,从而满足中继设备和终端的覆盖范围不一致的需求。To support different cyclic shifts for relay devices and terminal devices, the base station side configures the cyclic shift step of the relay device to be a multiple N (N is a positive integer) of the cyclic shift of the terminal device according to the coverage range of the covered relay device, to ensure that the relay device uses a cyclic shift step N times larger than that of the terminal to generate a random access sequence, thereby meeting the requirements of inconsistent coverage ranges of the relay device and the terminal.

这里需要指出的是,由于中继设备的随机接入速率相对较低,因此可以生成比终端更少数量的随机接入序列。It should be pointed out here that, since the random access rate of the relay device is relatively low, it can generate fewer random access sequences than the terminal.

如图3中所示,对于终端设备,当高层配置Ncs=10的时候,每个ZC序列需要13个循环移位来生成随机接入序列,一共需要5个ZC序列依据循环移位生成共64个随机接入序列,图中每一个方块表示一个随机接入序列;As shown in FIG3 , for a terminal device, when the high-layer configuration N cs =10, each ZC sequence requires 13 cyclic shifts to generate a random access sequence, and a total of 5 ZC sequences are required to generate a total of 64 random access sequences according to the cyclic shift. Each square in the figure represents a random access sequence;

依据本专利的高层配置,中继设备配置4倍大小的步长值,即Ncs=40来生成随机接入序列,每个根序列生成3个循环移位的随机接入序列,可以生成15个用于中继设备的随机接入序列。具体的循环移位的数值Cv为0,40,80。图中每一个方块表示一个随机接入序列,灰色方块表示第二随机接入序列的集合。在图3所示实施例中,所述第二随机接入序列的集合,包含全部的所述第二随机接入序列。According to the high-level configuration of this patent, the relay device configures a step value of 4 times the size, that is, N cs = 40 to generate a random access sequence. Each root sequence generates 3 cyclic shift random access sequences, and 15 random access sequences for the relay device can be generated. The specific cyclic shift value C v is 0, 40, and 80. Each square in the figure represents a random access sequence, and the gray square represents a set of second random access sequences. In the embodiment shown in Figure 3, the set of the second random access sequences includes all of the second random access sequences.

为避免冲突,所有N倍的循环移位均用于中继设备,剩下的循环移位用于终端。例子中的Cv=0,40和80用于中继设备。最终,用于中继的随机接入序列个数为15个,用于终端的随机接入序列个数为49个。即在全部第一随机序列中,去掉与灰色方块重合的部分(划×表示),得到第一随机序列的集合。To avoid conflicts, all N-fold cyclic shifts are used for relay devices, and the remaining cyclic shifts are used for terminals. In the example, C v = 0, 40 and 80 are used for relay devices. Finally, the number of random access sequences used for relays is 15, and the number of random access sequences used for terminals is 49. That is, among all the first random sequences, the parts that overlap with the gray blocks (indicated by ×) are removed to obtain a set of first random sequences.

图4为第二随机接入序列的集合包含部分第二随机接入序列的示意图。FIG4 is a schematic diagram showing that a set of second random access sequences includes a part of second random access sequences.

优选地,所述第二随机接入序列的集合,包含部分的所述第二随机接入序列。在所述第一随机接入序列的集合中,排除与所述第二随机接入序列的集合中任意一个相同的第一随机接入序列。所述第一随机序列集合和第二随机序列集合中包含的随机序列总数为64个。Preferably, the set of the second random access sequences includes part of the second random access sequences. In the set of the first random access sequences, the first random access sequences that are identical to any one in the set of the second random access sequences are excluded. The total number of random sequences included in the first random sequence set and the second random sequence set is 64.

基站给终端和中继配置其专用的根序列和循环移位,来保证终端和中继专用的接入序列,如图4所示,仍然取终端设备高层配置Ncs=10,中继设备Ncs=40。终端在第二个根序列生成随机接入序列的Cv=40,50,…,120,中继在第二个根序列生成随机接入序列的Cv=0。终端在第四个根序列生成随机接入序列的循环移位数值Cv=0,10,20,30,80,90,100,110,120;中继在第三个根序列生成随机接入序列的Cv=40。终端在第五个根序列生成随机接入序列的循环移位数值Cv=0,10,20,30,40,50,60,70,120;中继在第五个根序列生成随机接入序列的Cv=80。图中每一个方块表示一个随机接入序列,灰色方块表示第二随机接入序列的集合,是在所有的第二随机接入序列中指定的部分(其余划×表示)。这个例子中用于中继的随机接入序列个数为3个。在全部第一随机序列中,去掉与灰色方块重合的部分(划×表示),得到第一随机序列的集合,用于终端的随机接入序列个数为61个。The base station configures the terminal and the relay with their dedicated root sequences and cyclic shifts to ensure the dedicated access sequences for the terminal and the relay. As shown in FIG4 , the terminal device high-level configuration N cs = 10 and the relay device N cs = 40 are still taken. The terminal generates C v = 40, 50, ..., 120 for the random access sequence at the second root sequence, and the relay generates C v = 0 for the random access sequence at the second root sequence. The terminal generates C v = 0, 10, 20, 30, 80, 90, 100, 110, 120 for the random access sequence at the fourth root sequence; the relay generates C v = 40 for the random access sequence at the third root sequence. The terminal generates C v = 0, 10, 20, 30, 40, 50, 60, 70, 120 for the random access sequence at the fifth root sequence; the relay generates C v = 80 for the random access sequence at the fifth root sequence. Each square in the figure represents a random access sequence, and the gray square represents the set of second random access sequences, which is a specified part of all second random access sequences (the rest are indicated by crosses). In this example, the number of random access sequences used for relay is 3. Among all the first random sequences, the part overlapping with the gray square is removed (indicated by crosses), and the set of first random sequences is obtained. The number of random access sequences used for terminals is 61.

本发明中,终端和中继设备公用相同的序列,引入两种循环移位步长值,设计的原则是小的步长值用于终端设备,大的步长值用于中继设备。指示的方法有三种,一种是将可配置的步长值分成两类,使得一类稍大的步长值用于中继设备,另一类小的步长值用于终端设备,另外一种是给指示中继设备的步长值是终端设备步长值的倍数,第三种是直接配置生成的64个接入序列中按照高步长值的一部分随机接入序列给中继设备使用。In the present invention, the terminal and the relay device share the same sequence, and two cyclic shift step values are introduced. The design principle is that a small step value is used for the terminal device and a large step value is used for the relay device. There are three indication methods, one is to divide the configurable step value into two categories, so that a slightly larger step value is used for the relay device and the other small step value is used for the terminal device, another is to indicate that the step value of the relay device is a multiple of the step value of the terminal device, and the third is to directly configure a part of the random access sequences with a high step value among the generated 64 access sequences for the relay device to use.
