- MCS Maximum number of supported carriers
- MPC Multipoint Capability
- the overall idea of the method for expressing the multi-point transmission capability of the UE is: for the case where the maximum number of sectors is 2, the matrix representation is converted into a binary number; for the case where the maximum number of sectors is greater than 2, A classification notation is required.
- an exhaustive representation can also be employed.
- Method 1 Matrix representation, that is, the matrix capability of (MFS+1) X (MFS+1) is used to represent its capability range.
- Method 2 Classification representation. For the case where the MSS is further expanded, the attribute field is used to define it.
- Method 3 Exhaustive representation, when the multi-point transmission mode supported by the UE is very small, a special direct enumeration method is adopted, that is, enumerating the capabilities supported by the UE, and each combination relationship is performed by an integer number. Said. It should be noted that the present embodiment includes, but is not limited to, the above representation method, and the expressions extended by the matrix idea, the classification attribute idea, and the idea of numbering the multi-point transmission capability should also be included.
- Embodiment 2 Matrix Representation Take the UE with a maximum carrier frequency of 8 as an example, and the following (MFS+1) X (MFS+1) matrix capability is used to indicate its capability range.
- the horizontal axis represents the number of carriers used by one of the sectors, and the vertical axis represents the number of carriers corresponding to another sector.
- 1 indicates whether the UE supports the scenario, and 0 indicates that the channel is not supported. Change the scene.
- the black cell in the table indicates that the UE supports one sector using one carrier frequency and the other sector using five carrier frequencies for data reception.
- the scenario shown indicates that the UE does not support scenarios where the number of carrier frequencies of both sectors is greater than 4.
- the maximum number of carrier frequencies supported by the UE increases, it can be represented by simultaneously increasing the number of rows and columns of the matrix.
- the elements in the matrix are both 0 and 1
- a binary representation can be used, and, due to the definition, the matrix is strictly symmetric about the diagonal, that is, if the A sector X carrier frequencies are supported, the B fan The area y carrier frequency, then must also support A sector y carrier frequency, B sector X carrier frequency, can be compressed by matrix compression.
- the background of 3GPP Rell l is used to illustrate the use of the matrix representation in the implementation process.
- Form 2 Form 2:
- step S306 it can be found that the point above the black diagonal line and the point sent by the black diagonal line are completely symmetrical. Therefore, the entire matrix can be completely represented by only expressing the point below the black diagonal line and the black diagonal line.
- Original There is a matrix of 81 units, which can be fully represented by 45 units. Table 3 below renumbers these cells to an integer from 0 to 44.
- Step S308 the 0 and 1 of each cell are represented by a binary number, SP, and the matrix can be abstractly represented as a 45-bit binary number, which can be represented by two 32-bit numbers (WORD32), a total of 64 bits.
- WORD32 32-bit numbers
- the high position can also have a surplus of 19 bits, which is used to carry other special capability information and temporarily fill 0.
- the numbering method is as follows, the number of the nth digit is filled in by the content of the cell numbered n, the content of the diagonal stripe in Table 3 is 1, and the content of the grid part is 0; thus, the last obtained 2
- the hexadecimal number is: 00011 11110001 11110011 11101111 11111111 11111111; Converted to hexadecimal number: 0x03Fl 0xF3EF FFFF o Therefore, using these two 32-bit numbers can fully represent the UE multi-point transmission capability.
- Embodiment 3 Classification representation
- the classification notation in this embodiment is to use the number of sectors of the same frequency point as the primary classification attribute. For example, for the case where the MSS is 3, the division can be divided into three sectors, the same number of points, and two fans. The frequency band is the same, and the three sector frequency points are different. Then, sub-attributes can be defined under each primary classification attribute to indicate a more accurate capability representation. This idea can be further extended to the case of more sectors.
- the UE is divided into the following three categories of attributes in the capability representation, where 1 indicates support, 0 indicates no support, and each subclass has sub-attributes: (1) Supports that all sectors have different carrier frequencies: NoSectorFrequencySameCapality; Single sector carrier frequency MaxFrequecyNum; the difference between the maximum number of frequency points and the smallest number of frequency points (excluding 0) MaxGap;
- Step S400 Initialize all multi-point transmission capability attributes of the UE, that is, clear all UEs. Multi-point transmission capability attribute all fields; Step S402, if the UE supports all sectors with different carrier frequency numbers, then
- bitO represents the number of carrier frequencies is 1, bitl represents the number of carrier frequencies is 2, and so on; the frequency of another sector of different frequency points is filled into 2SectorFSC.DifferentFrequencyBitmap, bitO represents The number of frequencies is 1, bitl represents the number of carrier frequencies is 2, and so on; Step S410, if the number of individual frequency points can be greater than the number of frequency points of 2 sectors of the same frequency, fill in 2 S ectorF SC .
- bitO represents the number of carrier frequencies is 1
- bitl represents the number of carrier frequencies is 2
- Step S416 completing all fields of the UE multi-point transmission capability attribute. For example, for a UE with an MFS of 8 and an MSS of 3, if only three sectors are not supported, the carrier frequency is different, only three sectors are supported as one carrier frequency, or two sectors are two carrier frequencies. In addition, if one sector has 1 carrier frequency or no carrier frequency, you should fill in the following capabilities as follows:
- Embodiment 4 Exhaustive representation Since the attribute in the third embodiment cannot completely cover the UE, especially when the type of capability supported by the UE is very small, the embodiment provides a multipoint of the UE.
- the method of mapping the transmission capability to an integer uses a special enumeration method, and only indicates the capability supported by the UE. The following coding method can be adopted. First, define an integer to represent the MPC. The integer first has MSS bits, and each bit represents the number of sectors in the active set.
- Step S502 exhausting all kinds of capability configurations supported by the UE, and setting the UE
- the length of the capability array is the number; in step S504, each capability is converted into a number according to the above corresponding method; Step S506, each number is filled in a predefined array; Step S508, the length and content of the output array are output.
- Step S508 the length and content of the output array are output.
- Multi-point transmission convert them to numbers is 4 and 8, fill in the array, ie, the final completion is as follows:
- the attributes in the foregoing embodiments are all extensible. After the UE indicates these attributes, the UE supports the configuration attributes, and the network side can allocate according to the real-time wireless network quality conditions. Switch between the attribute states of the configuration.
- the embodiment of the present invention relates to a method for expressing a multi-point transmission capability of a UE in a multi-carrier wireless communication system, and adopts different methods according to the number of transmission capabilities supported by the UE and the maximum number of supported sectors to indicate multiple UEs.
- the point transmission support capability, and the simple mode of the multi-point transmission support capability of the UE is notified to the network side, and the capability of the multi-point transmission of the UE is comprehensively expressed, and the resources allocated by the network side to the UE are insufficient in the related art.
- the problem that the multi-point transmission operation fails to be established improves the processing capability and stability of the system.
- the invention is not limited to any specific combination of hardware and software.

Description
UE多点传输能力的表示方法及装置 技术领域 本发明涉及移动通信领域, 尤其涉及一种用户设备(User Equipment, 简称为 UE) 多点传输能力的表示方法及装置。 背景技术 在宽带码分多址 (Wideband Code Division Multiple Access, 简称为 WCDMA) 网 络中, 通用陆地无线接入网 (Universal Terrestrial Radio Access Network, 简称为 UTRAN)包括无线网络控制器(Radio Network Controller,简称为 RNC)和基站(NodeB) 两种基本网元。 随着 WCDMA网络的发展, 高速下行链路分组接入(High Speed Downlink Packet
Access, 简称为 HSDPA)、 高速上行链路分组接入 (High Speed Uplink Packet Access, 简称为 HSUPA)、 双小区高速下行分组接入 (Dual Cell-High speed downlink packet access,简称为 DC-HSDPA;)、双频段双小区高速下行分组接入(Dual band-Dual cell-high speed downlink packet access,简称为 DB-DC-HSDPA)、双小区高速上行分组接入(Dual Cell-high speed uplink packet access, 简称为 DC-HSUPA)、 四载波高速下行分组接入 (Four carrier-high speed downlink packet access, 简称为 4C-HSDPA), 八载波高速下行 分组接入 (Eight carrier-high speed downlink packet access, 简称为 8C-HSDPA)这些技 术陆续地被引入, 使得 UE的数据传输率不断得到提高。 作为实现这些技术的前提之 一, UE需要支持更多的频段和频段组合。 在支持的单频段内, UE需要支持更宽的带 宽; 在支持的双频段内, UE需要支持更多的双频段载波组合。 目前, 3GPP协议已经 完备地规范了 DC-HSDPA、 DB-DC-HSDPA和 DC-HSUPA, 4C-HSDPA这几种多载波 技术下, UE传输其支持的频段、 带宽及双频段载波组合信息的方式。 为了达到更高的数据吞吐量, 尤其是小区边缘的吞吐率, 经过 3GPP的技术分析 与论证, 提出一种增强功能: UE可以同时从不同 NodeB或相同的 NodeB的相同频点 或者同一频点的两个扇区同时接收数据块, 即, 在同一个传输时间间隔 TTI 内, UE 能接收到相当于传统模式二倍的数据块, 称为 DF-DC-HSDPA或者 SF-DC-HSDPA技 术。 在同一 NodeB接收不同小区数据块的模式称为 Intra-NodeB模式; 在不同 NodeB 接收不同小区数据块的模式称为 Inter-NodeB模式。 由此不难进一步推论,对于支持多 载波的 UE, UE将会支持在同一传输时间间隔(Transmission Time Interval,简称为 TTI)
内, UE可以在多个频点接收不同扇区的数据块,并且可能在不同的扇区内的频点数目 还可以不同。例如, 具备 4C-HSDPA能力的 UE, 可能支持在每个扇区内都采用 4C同 时进行接收数据, 也可能只能支持在一个扇区采用 4C接收数据; 或者只支持在两个 扇区内分别采用 2C接收数据; 或者同时也支持在一个扇区采用 1C接收数据, 另一个 扇区采用 2C接收数据。 但是, 在相关技术中, 由于 UE在各个扇区支持的最大下行载波个数并不固定, 所以, 网络侧在给 UE配置资源的时候, 可能会导致资源配置不够, 从而导致多点传 输操作建立失败。 发明内容 本发明的主要目的在于提供一种 UE多点传输能力的表示方案, 以至少解决上述 相关技术中由于网络侧给 UE配置的资源不够而导致多点传输操作建立失败的问题。 为了实现上述目的, 根据本发明的一个方面, 提供了一种 UE多点传输能力的表 示方法。 根据本发明实施例的 UE多点传输能力的表示方法, 包括以下步骤: UE根据其支 持的多点传输模式的个数, 确定 UE的多点传输支持能力的表示方式, 并使用该表示 方式表示 UE的多点传输支持能力; UE向网络侧发送 UE的多点传输支持能力。 优选地, UE根据其支持的多点传输模式的个数, 确定 UE的多点传输支持能力的 表示方式包括: 在 UE支持的多点传输模式的个数大于预定值的情况下, UE根据最大 扇区支持个数选择矩阵方式或分类方式来表示 UE的多点传输支持能力, 其中, 最大 扇区支持个数为 UE支持的同时接收数据的扇区数目; 在 UE支持的传输能力的个数 小于或等于预定值的情况下, UE采用穷举方式来表示 UE的多点传输支持能力。 优选地, UE根据最大扇区支持个数选择矩阵方式或分类方式来表示 UE的多点传 输支持能力包括:若最大扇区支持个数为 2,则选择矩阵方式来表示 UE的多点传输支 持能力;若最大扇区支持个数大于 2,则选择分类方式来表示 UE的多点传输支持能力。 优选地, 上述选择矩阵方式来表示 UE的多点传输支持能力包括: 建立以 UE支 持的 2个扇区中的一个扇区所使用的载频数为横轴, 以 UE支持的 2个扇区中的另一 个扇区所使用的载频数为纵轴的矩阵; 若 UE同时支持矩阵中横轴和纵轴所标识的载 频数, 则在矩阵对应的单元中填入 1 ; 否则, 在该单元中填入 0; 将矩阵中所有单元的 信息转换为二进制数, 以表示 UE的多点传输支持能力。
优选地, 上述矩阵为 M x M的方阵, 其中, M为最大载频支持个数加 1。 优选地, 上述选择分类方式来表示 UE的多点传输支持能力包括: 按照 UE支持 相同的频点数扇区的数目对 UE的多点传输支持能力划分子类别; 并根据最大单扇区 载频数和扇区的频点数情况在每个子类别中再划分子属性; 对每个子类别中的子属性 一一赋值, 以表示 UE的多点传输支持能力。 优选地, UE采用穷举方式来表示 UE的多点传输支持能力包括: 列举出 UE所支 持的频点和扇区的组合; 使用 N进制的整数来标识每种组合下对应的 UE的多点传输 支持能力, 其中, N为最大载频支持个数加 1。 优选地, UE向网络侧发送 UE的多点传输支持能力之后, 该方法还包括: 网络侧 接收 UE的多点传输支持能力, 并根据该多点传输支持能力对 UE进行资源配置。 为了实现上述目的, 根据本发明的另一方面, 还提供了一种 UE多点传输能力的 表示装置。 根据本发明的 UE 多点传输能力的表示装置, 包括: 确定模块, 设置为根据 UE 支持的多点传输模式的个数, 确定 UE的多点传输支持能力的表示方式; 表示模块, 设置为使用确定模块确定的表示方式表示 UE的多点传输支持能力; 发送模块, 设置 为向网络侧发送 UE的多点传输支持能力。 优选地, 确定模块还设置为在 UE支持的多点传输模式的个数大于预定值的情况 下,根据最大扇区支持个数选择矩阵方式或分类方式来表示 UE的多点传输支持能力, 其中, 最大扇区支持个数为 UE支持的同时接收数据的扇区数目; 以及在 UE支持的 传输能力的个数小于或等于预定值的情况下, 采用穷举方式来表示 UE的多点传输支 持能力。 通过本发明, 采用 UE根据其支持的多点传输模式的个数, 确定 UE的多点传输 支持能力的表示方式, 并使用表示方式表示 UE的多点传输支持能力, 以及将该表示 后的 UE的多点传输支持能力告知网络侧的方式,解决了相关技术中由于网络侧给 UE 配置的资源不够而导致多点传输操作建立失败的问题, 提高了系统的处理能力和稳定 性。
附图说明 此处所说明的附图用来提供对本发明的进一步理解, 构成本申请的一部分, 本发 明的示意性实施例及其说明用于解释本发明, 并不构成对本发明的不当限定。 在附图 中: 图 1是根据本发明实施例的 UE多点传输能力的表示方法的流程图; 图 2是根据本发明实施例的 UE多点传输能力的表示装置的结构框图; 图 3是根据本发明实施例的实施例二的矩阵表示法的流程图; 图 4是根据本发明实施例的实施例三的分类表示法的流程图; 图 5是根据本发明实施例的实施例四的穷举表示法的流程图。 具体实施方式 下文中将参考附图并结合实施例来详细说明本发明。 需要说明的是, 在不冲突的 情况下, 本申请中的实施例及实施例中的特征可以相互组合。 根据本发明实施例, 提供了一种 UE多点传输能力的表示方法。 图 1是根据本发 明实施例的 UE多点传输能力的表示方法的流程图, 如图 1所示, 包括以下步骤: 步骤 S102, UE根据其支持的多点传输模式的个数, 确定 UE的多点传输支持能 力的表示方式; 步骤 S104, UE使用表示方式表示 UE的多点传输支持能力; 步骤 S106, UE向网络侧发送 UE的多点传输支持能力。 通过上述步骤, 采用 UE根据其支持的多点传输模式的个数, 确定 UE的多点传 输支持能力的表示方式, 并使用表示方式表示 UE的多点传输支持能力, 以及将该表 示后的 UE的多点传输支持能力告知网络侧的方式, 解决了相关技术中由于网络侧给 UE配置的资源不够而导致多点传输操作建立失败的问题,提高了系统的处理能力和稳 定性。 优选地,在步骤 S102中,在 UE支持的多点传输模式的个数大于预定值的情况下, UE可以根据最大扇区支持个数选择矩阵方式或分类方式来表示 UE的多点传输支持能 力, 其中, 最大扇区支持个数为 UE支持的同时接收数据的扇区数目; 在 UE支持的
传输能力的个数小于或等于预定值的情况下, UE可以采用穷举方式来表示 UE的多点 传输支持能力。该方法针对不同的情况选择不同的表示方式,提高了系统的适应能力。 优选地, UE根据最大扇区支持个数选择矩阵方式或分类方式来表示 UE的多点传 输支持能力包括:若最大扇区支持个数为 2,则选择矩阵方式来表示 UE的多点传输支 持能力;若最大扇区支持个数大于 2,则选择分类方式来表示 UE的多点传输支持能力。 该方法可以提高系统的有效性。 优选地, 选择矩阵方式来表示 UE的多点传输支持能力包括: 建立以 UE支持的 2 个扇区中的一个扇区所使用的载频数为横轴, 以 UE支持的 2个扇区中的另一个扇区 所使用的载频数为纵轴的矩阵; 若 UE同时支持矩阵中横轴和纵轴所标识的载频数, 则在矩阵对应的单元中填入 1 ; 否则, 在该单元中填入 0; 将矩阵中所有单元的信息转 换为二进制数, 以表示 UE的多点传输支持能力。该方法适用于最大扇区支持个数为 2 的情况, 提高了系统效率。 优选地, 矩阵为 M x M的方阵, 其中, M为最大载频支持个数加 1。 该方法简单 实用、 可操作性强。 优选地, 选择分类方式来表示 UE的多点传输支持能力包括: 按照 UE支持相同 的频点数扇区的数目 (即, UE支持同时接收的扇区的数目)对 UE的多点传输支持能 力划分子类别; 并根据最大单扇区载频数和扇区的频点数情况在每个子类别中再划分 子属性; 对每个子类别中的子属性一一赋值, 以表示 UE的多点传输支持能力。 该方 法适用于最大扇区支持个数大于 2的情况, 分类分层次表示化简了表示流程, 提高了 系统的处理能力。 例如, UE支持同时接收的扇区为 3, 其中, 可能有 0、 2、 3个扇区的频点数相同, 这里 "0"表示所有扇区频点数均不同, "2"表示 2个扇区的频点数相同且另外 1个频点 数不同, "3"表示 3个扇区的频点数均相同。 优选地, UE采用穷举方式来表示 UE的多点传输支持能力包括: 列举出 UE所支 持的频点和扇区的组合; 使用 N进制的整数来标识每种组合下对应的 UE的多点传输 支持能力, 其中, N为最大载频支持个数加 1。该方法适用于 UE的多点传输支持能力 较少的情况, 可以有效地利用系统资源。 优选地, 在步骤 S106之后, 网络侧接收 UE的多点传输支持能力, 并根据该多点 传输支持能力对 UE进行资源配置。 该方法可以提高系统的性能。
对应于上述方法,本发明实施例还提供了一种 UE多点传输能力的表示装置。图 2 是根据本发明实施例的 UE多点传输能力的表示装置的结构框图, 如图 2所示, 该装 置 20包括: 确定模块 22, 设置为根据 UE支持的多点传输模式的个数, 确定 UE的多 点传输支持能力的表示方式; 表示模块 24, 耦合至确定模块 22, 设置为使用确定模块 22确定的表示方式表示 UE的多点传输支持能力; 发送模块 26, 耦合至表示模块 24, 设置为向网络侧发送 UE的多点传输支持能力。 通过上述装置 20, 采用确定模块 22根据 UE支持的多点传输模式的个数, 确定 UE的多点传输支持能力的表示方式, 表示模块 24使用表示方式表示 UE的多点传输 支持能力,以及发送模块 24将该表示后的 UE的多点传输支持能力告知网络侧的方式, 解决了相关技术中由于网络侧给 UE配置的资源不够而导致多点传输操作建立失败的 问题, 提高了系统的处理能力和稳定性。 优选地,确定模块 22还用于在 UE支持的多点传输模式的个数大于预定值的情况 下,根据最大扇区支持个数选择矩阵方式或分类方式来表示 UE的多点传输支持能力, 其中, 最大扇区支持个数为 UE支持的同时接收数据的扇区数目; 以及在 UE支持的 传输能力的个数小于或等于预定值的情况下, 采用穷举方式来表示 UE的多点传输支 持能力。 优选地, 该装置 20可以设置在 UE中。此时, RNC可以对 UE发送的多点传输支 持能力进行解析。 下面结合优选实施例和附图对上述实施例的实现过程进行详细说明。 实施例一 本实施例提供了一种 UE的多点传输能力的表示方法, 用于表述 UE对于载波数 以及同时接收扇区数的组合关系, 从而在上述网络侧给 UE配置资源的场景下, UE可 以通过合适的信令, 把其支持的各个扇区的频点数目信息发送给网络。 网络侧只有正 确接收到这些信息之后, 才能分配给 UE合适的无线资源, 做出合理的配置, 进而运 行良好。 如果网络能提前获悉 UE在各个扇区支持的最大下行载波个数, 在给 UE配 置资源的时候, 就能准确地进行配置, 这样保证了最大限度的利用 UE所支持的能力。 首先, 可以需要定义几个基本的变量: 最大扇区支持个数(MaxSectorSupport, 简 称为 MSS ) : UE 支持的同时接收数据的扇区数目; 最大载频支持个数 (MaxFrequency Support,简称为 MFS): UE在某个扇区上最大支持同时接收数据的频 点个数; 多点传输支持能力 (MultiPointCapability, 简称 MPC, 即本发明实施例中阐
述的 UE的综合能力): 包括支持在若干个扇区上, 每个扇区若干数目的载频上支持同 时接收数据的组合能力。 本实施例提供的 UE多点传输能力的表示方法的整体思路为:对于最大扇区数为 2 的情况, 用矩阵表示法, 转化为二进制数来定义; 对于最大扇区数大于 2的情况, 需 要采用分类表示法。 另外, 当 UE支持的多点传输模式非常少的时候, 还可以采用穷 举表示法。 下面对这三种方法做个简单介绍。 方法一: 矩阵表示法, 即, 用 (MFS+1 ) X (MFS+1 ) 的矩阵能力来表示其能力 范围。 方法二: 分类表示法, 对于 MSS进一步扩大的情况, 采用属性字段的方式进行定 义。 方法三: 穷举表示法, 当 UE支持的多点传输模式非常少的时候, 采用特殊的直 接列举说明的方法, 即, 列举 UE支持的能力, 将每一种组合关系用一个整数编号来 进行表示。 需要说明的是, 本实施例包括但不仅限于以上的表示方法, 由矩阵思路、 分类属 性思路以及对多点传输能力的进行编号的思路, 延伸开去的表达方式应该也包含在其 中。 实施例二: 矩阵表示法 以最大 8载频的 UE为例, 用以下的 (MFS+1 ) X (MFS+1 ) 的矩阵能力来表示其 能力范围。 如表格一, 横轴表示其中一个扇区所使用的载频数, 纵轴表示另一个扇区 对应的载频数, 对于矩阵中的每个单元, 1表示该 UE是否支持该场景, 0表示不支持 改场景。 例如, 表格中的黑色单元表示 UE支持其中一个扇区使用一个载频, 另一个 扇区使用 5个载频, 同时进行数据接收。 表格一:
OF IF 2F 3F 4F 5F 6F 7F 8F
OF 1 1 1 1 1 1 1 1 1
IF 1 1 1 1 1 1 1 1
2F 1 1 1 1 1 1 1 1 1
3F 1 1 1 1 1 1 1 1 1
4F 1 1 1 1 1 1 1 1 1
5F 1 1 1 1 1 0 0 0 0
6F 1 1 1 1 1 0 0 0 0
7F 1 1 1 1 1 0 0 0 0
8F 1 1 1 1 1 0 0 0 0 从上述表格中所有的多点传输支持能力来看, 所示的场景, 表示 UE不支持两个 扇区的载频数目都大于 4的场景。 通过上述方法, 可以完全表达某个 UE在两扇区的情况下, 对 8个载频的支持能 力。 优选地, 如果 UE支持的最大载频数增加, 则可以通过同时增加矩阵的行数和列 数进行表示。 优选地, 由于矩阵中的元素都为 0和 1, 可以采用二进制表示, 并且, 由于定义 的缘故, 该矩阵是关于对角线严格对称的, 即如果支持 A扇区 X个载频, B扇区 y个 载频, 那么也必然支持 A扇区 y个载频, B扇区 X个载频, 可以采用矩阵压缩的方式, 对其进行压缩。 下面针对 3GPP Rell l的背景,举例说明该矩阵表示法在实施过程中的使用。例如,
MSS = 2, MFS = 8。 图 3是根据本发明实施例的实施例二的矩阵表示法的流程图, 如 图 3所示, 该流程包括以下步骤: 步骤 S302, 绘制如下 (MFS+1 ) (MFS+1 ) 的矩阵。 步骤 S304, 将 UE多点传输能力填入, 如果 UE同时支持横轴载频数和纵轴载频 数配合, 则将对应的方框填入 1, 否则填入 0, 如下表格二所示。 表格二:
步骤 S306,可以发现黑色对角线上方的点和黑色对角线下发的点完全对称,因此, 只用表达黑色对角线下方的点以及黑色对角线就可以将整个矩阵完全表示, 这样, 原
来有 81个单元的矩阵, 可以用 45个单元完整表示。 如下表格三, 将这些单元格重新 编号到 0~44的整数。
步骤 S308 , 将每一个单元格的 0和 1用二进制数来表示, SP, 将这个矩阵可以抽 象表示成一个 45位的二进制数, 可以用两个 32位数 (WORD32)来表示, 共 64位, 高 位还能富余 19bit, 用于携带其他特殊能力信息, 暂时补 0。 在实施过程中, 编号方式如下所示, 第 n位的数由编号为 n的单元格内容填入, 表格三中斜条纹部分内容为 1,网格部分内容为 0;这样,最后得到的 2进制数为: 00011 11110001 11110011 11101111 11111111 11111111; 转化为 16 进制数为: 0x03Fl 0xF3EF FFFF o 因此, 用这两个 32位数就可以完整表示 UE多点传输能力。 实施例三: 分类表示法 对于 MSS进一步扩大的情况, 如果单纯采用将矩阵扩大到立方体, 并且进行全排 列罗列的方法, 耗费的二进制数将非常多, 并且对其编号也比较复杂, 因此, 可以采 用属性字段的方式进行定义。 本实施例中的分类表示法,是将其中相同的频点数扇区的数目作为一级分类属性, 例如,对于 MSS为 3的情况,可以分为 3个扇区频点数都相同、 2个扇区频点数相同、 3 个扇区频点数都不同三种情况。 然后, 每个一级分类属性下可以定义子属性, 用来 表明更加精确的能力表述。 这种思路也可以进一步扩展到更多扇区的情况中去。 下面针对 3GPP Rell2的背景, 举例说明该矩阵表示法在实施过程中的使用。对于 MSS = 3 , MFS = 8的情况, 如果按照实施例二中的方法, UE多点传输能力从矩阵转 化为一个立方体, 单元格的总数为 (MFS+1 ) (MFS+1 ) (MFS+1 ) , 也就是 9χ9χ9 = 729个单元格。这样即使将重复的情况去除, 仍然有很多组合情况, 并且将其用数字
编号的方法, 对应关系比较繁琐, 而对于 UE来说, 也不需要区分的如此详细。 因此, 对于 MSS为 3的情况, 可以采用以下的能力表达方法。 首先, UE在能力表示中分以下三个大类属性, 1表示支持, 0表示不支持, 每大 类下分一些子属性: ( 1 ) 支持所有扇区载频数都不相等情况: NoSectorFrequencySameCapality; 最大单扇区载频数 MaxFrequecyNum; 最大的频点数和最小的频点数之间的差值 (不包括 0) MaxGap;
(2) 支持所有扇区 2个载频数相等情况: 2SectorRequencySameCapality; 2个相同频点数扇区的频点数最大值 SameFrequecyNumBitmap; 另一个不同频点数扇区的频点数情况 DifferentFrequencyBitmap; 表示单独的频点数是否能大于 2个相同频点数扇区的频点数(1代表可以, 0代表 不可以 ) DifFerentFrequencyExceed S ameFrequecy; 最大的频点数和最小的频点数之间的差值 (不包括 0) MaxGap;
(3 ) 支持所有扇区 3个载频数相等情况: 3SectorRequencySameCapality; 3个相同频点数扇区的频点数最大值 SameFrequecyNumBitmap。 图 4是根据本发明实施例的实施例三的分类表示法的流程图, 如图 4所示, 该流 程包括以下步骤: 歩骤 S400, 初始化 UE所有多点传输能力属性, 即, 清空所有 UE多点传输能力 属性所有字段; 步骤 S402, 如果 UE 支持所有扇区载频数都不相同的情况, 则置
NoSectorFrequencySameCapality = 1 , 否贝1 J, NoSectorFrequencySameCapality = 0, £兆转 到步骤 S406; 步骤 S404, 将所有扇区载频数都不相同的情况下, UE支持某扇区下最多载频数 填入 NoSectorFSC.MaxFrequecyNum; 将最大的频点数和最小的频点数之间的差值填 入 NoSectorFSC.MaxGap;
步骤 S406, 如果 UE 支持 2 个扇区载频数相同的情况, 则置 2SectorFrequencySameCapality = 1 , 否贝1 J, 2SectorFrequencySameCapality = 0, 跳转至 lj S412; 步骤 S408, 将 2 个相 同频点数扇 区 的频点数支持情况填入 2SectorFSC. SameFrequecyNumBitmap, bitO代表载频数目为 1, bitl代表载频数目为 2, 以 此 类 推 ; 将 另 一 个 不 同 频 点 数 扇 区 的 频 点 数 情 况 填 入 2SectorFSC.DifferentFrequencyBitmap, bitO代表载频数目为 1, bitl代表载频数目为 2, 以此类推; 步骤 S410, 如果单独的频点数能大于 2 个相同频点数扇区的频点数, 则填写 2 S ectorF S C . DifferentFrequencyExceed S ameFrequecy = 1 , 否 贝1 J , 填 写 2SectorFSC.DifferentFrequencyExceedSameFrequecy = 0;将最大的频点数和最小的频点 数之间的差值 (不包括 0) 填写到 2SectorFSC.MaxGap; 步骤 S412, 如果 UE 支持 3 个扇区载频数相同的情况, 则置 3SectorFrequencySameCapality = 1 , 否贝1 J, 3SectorFrequencySameCapality = 0, 跳转至 lj S416; 步骤 S414, 将 3 个相 同频点数扇 区 的频点数支持情况填入 3 SectorFSC. SameFrequecyNumBitmap , bitO代表载频数目为 1, bitl代表载频数目为 2, 以此类推; 步骤 S416, 完成 UE多点传输能力属性所有字段的填写。 例如, 对于一个 MFS为 8, MSS为 3的 UE, 如果只不支持 3个扇区的载频数都 不同, 只支持 3个扇区都是一个载频, 或者 2个扇区是 2个载频, 另外, 一个扇区 1 个载频或没有载频的情况, 则应该如下填写下面的能力:
( 1 ) No S ectorFrequency S ameCap ality = 0;
(2) 2SectorFrequencySameCapality = 1; 2 SectorFSC. SameFrequecyNumBitmap = 0x03;
2 S ectorF S C . DifferentFrequencyB itmap = 0x1; 2 S ectorF S C . DifferentFrequencyExceed S ameFrequecy = 0;
2SectorFSC.MaxGap = 1;
(3 ) 3 SectorFrequencySameCapality = 1; 3 SectorFSC. SameFrequecyNumBitmap = 0x1。 实施例四: 穷举表示法 由于实施例三中的属性不可能完全覆盖 UE的情况, 特别是当 UE支持的能力类 型非常少的时候, 所以, 本实施例提供了一种将 UE的多点传输能力映射到一个整数 上的方法, 采用特殊列举说明的方法, 只指出 UE支持的能力即可, 可以采用如下的 编码方式。 首先, 定义一个整数来表示 MPC, 该整数首先有 MSS位, 每一位代表激活集中 的扇区个数。 每一位的具体数值用 (MFS+1)进制数来表示, 其中, 0代表不支持, 1代 表支持, MFS代表当前使用的频点个数。 例如, 对于单频点 2扇区, 共有 4种状态, 按照上面的说法, 表示为:
MPC= 11(2进制) = 3; MPC= 10(2进制) = 2; MPC= 01(2进制) = 1; MPC= 00(2 进制) = 0。 例如, 对于 2频点 2扇区, 共有 9种状态, 按照上面的说法, 表示为:
MPC= 22(3进制) = 8; MPC= 21(3进制) = 7; MPC= 20(3进制) = 6; MPC= 12(3 进制) = 5;
MPC= 11(3进制) = 4; MPC= 10(3进制) = 3 ; MPC= 02(3进制) = 2; MPC= 01(3 进制)= 1 ; MPC= 00(3进制) = 0。 相应地, 对于 8频点 2扇区, 共有 81种状态, 可以用 0〜80进行表示。 继续扩展,对于 F频点, S扇区,共有 (F+1)的 S次方种能力组合,可以用 0〜(F+1)S 来进行表示。 可见, 采用本实施例中的穷举表示法, UE只需要定义一个数组, 数组的长度为支 持的模式数目, 数组的每一个单元是支持模式所对应的编号即可。
图 5是根据本发明实施例的实施例四的穷举表示法的流程图, 如图 5所示, 该流 程包括以下步骤: 步骤 S502, 穷举 UE支持的各种所有能力配置数目, 设置 UE能力数组的长度为 该数目; 步骤 S504, 将每一种能力按照上面的对应方法转化为数字; 步骤 S506, 将每一个数字填入预先定义好的数组中; 步骤 S508, 输出数组的长度和内容, 即为 UE的多点传输能力。 例如, 2频点 2扇区的 UE, 如果只支持两个扇区频点相同的配置, 也就是指支持 前面的 MPC= 11(3进制), MPC= 22(3进制)这两种多点传输, 将他们转化为数字就是 4和 8, 填入数组, 即, 最后完成如下:
MPS.n = 2;
MPS[0] = 4, MPS[1] = 8。 需要说明的是, 以上实施例中的属性都具备可扩展性, 当 UE指明了这些属性之 后, 即表示 UE支持该种配置属性, 网络侧可以根据实时的无线网络质量情况来进行 分配以及在各种配置的属性状态之间切换。 综上所述, 本发明实施例涉及多载波无线通信系统中 UE多点传输能力的表达方 法,采用根据 UE支持的传输能力的个数及最大扇区支持个数选择不同方式来表示 UE 的多点传输支持能力, 并将该表示后的 UE的多点传输支持能力告知网络侧的简单方 式, 全面地表述了 UE多点传输的能力, 解决了相关技术中由于网络侧给 UE配置的 资源不够而导致多点传输操作建立失败的问题, 提高了系统的处理能力和稳定性。 显然, 本领域的技术人员应该明白, 上述的本发明的各模块或各步骤可以用通用 的计算装置来实现, 它们可以集中在单个的计算装置上, 或者分布在多个计算装置所 组成的网络上, 可选地, 它们可以用计算装置可执行的程序代码来实现, 从而可以将 它们存储在存储装置中由计算装置来执行,或者将它们分别制作成各个集成电路模块, 或者将它们中的多个模块或步骤制作成单个集成电路模块来实现。 这样, 本发明不限 制于任何特定的硬件和软件结合。
以上所述仅为本发明的优选实施例而已, 并不用于限制本发明, 对于本领域的技 术人员来说, 本发明可以有各种更改和变化。 凡在本发明的精神和原则之内, 所作的 任何修改、 等同替换、 改进等, 均应包含在本发明的保护范围之内。
