- the access node configures the calculation amount of the CSI measurement of the 24ports as described above in the configuration mode 1, the UE cannot be configured to perform CSI reporting every 4 slots (such as in the fifth slot unit (slot 4)), so that the UE cannot The measurement is completed and reported. Therefore, the configuration 1 mode is an unavailable configuration.
- the access node configures the UE to perform CSI reporting in a periodic or semi-continuous manner, and also performs CSI reporting in every four slot units.
- each slot can support up to 4 ports, so the UE needs at least 4 slots to complete the 16ports measurement calculation.
- the access node is configured with the calculation amount of the CSI measurement of the 16ports and the reporting period (every 4 slots) as in the configuration mode 2, the UE can report the corresponding measurement according to the configuration. So the way to configure 2 is the available configuration.
- FIG. 7 is a schematic diagram of a configuration manner in which an access node configures a non-periodic CSI reporting of a UE according to a CSI reporting capability of a UE.
- the maximum support 16portS c slot so the access node and the UE measurement reporting CSI configuration, each slot should be considered maximum supportable UE 16ports, UE performed when the CSI is reported to complete the calculation of the amount of the corresponding CSI measurement can be performed CSI reported.
- the access node configures a timing offset of the non-period reporting of the UE, where the time offset is reported by the access node to send the CSI triggering time domain unit to the CSI.
- the interval between the inter-domain units, as shown in Fig. 7, is set to 5slots.
- CSI measurement 1 For CSI measurements, multiple measurements and reports (eg, CSI measurement 1, CSI measurement 2) can be performed based on various factors (eg, changes in interference).
- CSI measurement 1 the number of reported reports reported by the UE is two, corresponding to CMR setl and IMR setl, CMR set2, and IMR set2, respectively.
- the number of reported reports reported by the UE is two, corresponding to CMR setl and IMR set3, CMR set2, and IMR set4, respectively.
- the IMR set3 with 8ports
- the eighth slot configures the IMR set3 with 16ports
- the other is unchanged. If the access node is configured to trigger CSI measurement 2 in slot 6, then the UE has space and the base station can trigger a new CSI report. The access node can be configured to trigger at this moment. This configuration is available.
- FIG. 8 is a schematic diagram showing another configuration manner in which an access node configures UE non-periodic CSI reporting according to the CSI reporting capability of the UE.
- the time offset arrangement 1, the access node configuration aperiodic reporting UE is still 5slotS c 8 1 for CSI measurement
- the number of reports reported by the UE is set configuration 2
- the access node is configured with CPORT setl containing 8ports for CSI measurement in the first slot unit (slot 0)
- CMR set2 containing 16ports is configured in the second slot unit (slot 1)
- the sixth slot unit (slot 5) configures the IMR setl containing 8ports for CSI measurement, and sends the IMR setl containing 16ports in the seventh slot unit (slot 6): visible, the total calculation of the CSI measurement 1 to be calculated by the UE
- the number of reported reports reported by the UE is two, corresponding to CMR setl and IMR set3, CMR set2, and IMR set4, respectively.
- the configuration of the access node needs to consider the relationship between the time when the CMR set and the IMR set are sent and the time before the UE reports the time. For example, if the access node triggers the reporting of CSI measurement 1 at the end of slot 1 according to configuration mode 1, after a preset time offset, the UE should report at the end of slot 6, and because IMR setl ( 8ports) and IMR set2 (16ports) are sent in slots 5 and slot 6, respectively. Then, in slot 6, the UE is not idle yet, and the interference measurement set calculation must be processed.
- the access node cannot be configured to trigger CSI in slot 6.
- the measurement of the measurement 2 at least after the end of the slot 6, the UE processes the calculation of the CSI measurement 1, in order to trigger the CSI measurement 2.
- the UE needs to report at the end of slot 6, if the sum of the ports of IMR setl and IMR set2 exceeds the UE in two The number of ports supported by the unit, that is, 32ports, then the UE cannot complete the allocation in slot 6. The calculated amount cannot be reported.

Description
一种用于终端设备能力传输的方法、 装置及系统 本申请要求于 2018年 1月 12 日提交中国专利局、 申请号为 201810032046.X、 发明 名称为“一种用于终端设备能力传输的方法、 装置及系统”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。 技术领域
本申请涉及通信技术领域, 更具体地, 涉及通信系统中的终端设备能力传输的技术。 背景技术
下一代移动通信系统要求大容量和高质量的数据传输。大规模多输入多输出(Massive Multi-Input Multi- Output, 简称 Massive MIMO)技术被认为是可实现未来高速数据传输的 关键技术之一, 该技术通过使用大规模天线, 实现频谱效率的显著提升。 而基站可以获 取的信道状态信息 (CSI) 的准确性在很大程度上决定了 Massive MIMO 的性能。 信道 状态信息 (Channel State Information, 简称为 CSI) 是为了让基站能够获得下行传输的信 道状况和干扰情况, 由用户设备(User Equipment, 简称为 UE)对下行传输信道进行测量, 对测量结果的量化获得并进行上报。
针对 CSI的测量和结果上报, 基站需预先根据 UE的 CSI上报能力配置 CSI测量和 上报的相应参数。 而在长期演进(Long Term Evolution, 简称为 LTE)通信系统的 Rl l、 R12 和 R13几个版本中, 皆将 UE的 CSI上报能力定义为 UE上报能处理的 CSI进程 (CSI process) 的个数。 在新空口 (Next Radio, 简称为 NR) 中定义了一套灵活的 CSI配置框 架, 用于 CSI测量时, 基站会配置一个测量集 (measurement setting) , 一个或者多个上 报集(reporting setting),一个或者多个资源集(Resource setting)。每个 measurement setting 包含一个或者多个链路 (Link) , 每个 Link 用于连接一个 reporting setting和 Resource setting, 并且指示是用于信道测量还是干扰测量。 每个 reporting setting 包含 CSI上报的 内容和所占时频域资源位置, 每个 resource setting 包含用于 CSI 测量的参考信号 ( Reference Signal, 简称为 RS) 资源所占时频域资源位置。 而目前 NR中中讨论的潜在 方式是将 UE的 CSI上报能力定义为 UE上报能处理的 reporting setting的个数。
然而, 无论是 CSI process的个数还是 reporting setting的个数, 由于 CSI process和 reporting setting的配置情况很多, UE在考虑上报能力时只能根据最差 (即, 最耗计算量) 的情况来评估, 都无法真实代表 UE的在 CSI上报方面的计算能力, 同时对 CSI的测量 上报也限制了自由度。 发明内容

为使本申请解决的技术问题、 采用的技术方案和达到的技术效果更加清楚, 下面将 以实施例的形式结合附图对本申请的技术方案作进一步详细的描述。 所述详细的描述通 过使用方框图、 流程图和 /或示例提出了设备和 /或过程的各种实施例。 由于这些方框图、 流程图和 /或示例包含一个或多个功能和 /或操作,所以本领域技术人员将理解可以通过许 多硬件、 软件、 固件或它们的任意组合单独和 /或共同实施这些方框图、 流程图或示例内 的每个功能和 /或操作。
本申请中“多个”是指两个或两个以上。 本申请中的术语“和 /或”, 仅仅是一种描述关
联对象的关联关系, 表示可以存在三种关系, 例如, A和 /或 B, 可以表示: 单独存在 A, 同时存在 A和 B, 单独存在 B这三种情况。 另外, 本文中字符“/”, 一般表示前后关联对 象是一种“或”的关系。 本申请中的术语“第一”、 “第二”、 “第三”、 “第四”等是为了区分不 同的对象, 并不限定该不同对象的顺序。
本申请中, 名词“网络”和“系统”经常交替使用, 但本领域的技术人员可以理解其含 义。 本申请所提及的所有 “终端” /“终端设备”, 在一些情况下可以是指移动设备, 例如 移动电话、 个人数字助理、 手持或膝上型计算机以及具有电信能力的类似设备, 有些情 况下还可以是穿戴设备或车载设备等, 并包括未来 5G 网络中的终端或者未来演进的 PLMN 网络中的终端等。 这种终端可以包括设备及其相关联的可移除存储模块 (例如但 不限于 :包括订户标识模块 (Subscriber Identification Module, 简称为 SIM)应用、 通用订户 标识模块 (Universal Subscriber Identification Module, 简称为 USIM)应用或可移除用户标 识模块 (Removable User Identity Module, 简称为 R-UIM)应用的通用集成电路卡 (Universal Integrated Circuit Card, 简称为 UICC) ) ) 。 备选地, 这种终端可以包括没有这种模块的 设备本身。 在其它情况下, 术语“终端” /“终端设备”可以是指具有类似能力但是不可携 带的设备, 例如, 台式计算机、 机顶盒或网络设备。 术语“终端” /“终端设备”还可以是 指可端接用户的通信会话的任何硬件或软件组件。 此外, “用户终端” 、 “User Equipment”、 “UE” 、 “站点” 、 “station” 、 “STA”、 “用户设备” 、 “用户代理” 、 “User Agent” 、 “UA” 、 “用户装备” 、 “移动设备”和“设备”等皆是与本文中 “终 端” /“终端设备”同义的替代术语。 为方便描述, 本申请中, 上面提到的设备统称为用户 设备或 UEc
本申请中提及的 “接入节点” , 是一种网络设备, 部署在无线接入网中用以为终端 设备提供无线通信功能的装置, 能够负责调度和配置给 UE 的下行参考信号等功能。 所 述接入节点可以包括各种形式的宏基站、 微基站、 中继站、 接入点等等, 包括作为对传 统无线电信系统中的对等设备改进的系统和设备。 这种高级或下一代设备可以包含在长 期演进 LTE 通信系统、 5G通信系统、 未来演进系统或者多种通信融合系统中, 例如, LTE系统中包括的演进通用陆地无线接入网节点 B(E-UTRAN Node B, 简称为 eNB)、 5G 包括的新无线接入网节点 B (New Radio Access NodeB, 简称为 NR NodeB ) 、 其他无线 接入点或类似组件, 在采用不同的无线接入技术的系统中, 具备接入节点功能的设备名 称可能会有所不同。 为方便描述, 本申请中, 上述为 UE 提供无线通信功能的装置统称 为接入节点。
图 1 给出了本申请涉及的一种网络系统架构, 该系统用于 UE 的能力上报和信道状 态信息 (Channel State Information, 简称为 CSI) 测量, 其包括 UE100和接入节点 200, 图 1 中以 UE100在移动过程中, 与接入节点 200从建立连接到 CSI测量的两个阶段为示 例。 可选的, 如果该网络是以用户为中心、 网络跟着用户移动而追踪的网络, 那么系统 还包括至少一个传输接收点 300 (transmission and reception point, 简称为 TRP) , 这些 传输接收点 300具备其所在区域对应接入节点 200的一些功能, 能够部分替代接入节点 200, 与 UE100 之间进行交互, 还能够在特定场景下具备特定的用途, 例如能够监听未 接入的非激活态用户发送的上行跟踪参考信号, 以用户为中心, 跟随用户的移动, 进行 监听; 在用户激活与接入节点 200 建立连接后, UE 能力的上报也可以通过传输接收点 300发给接入节点 200。
在 UE100与接入节点 200建立连接后, UE100会将自身的能力进行上报, 以便接入 节点 200进行相应的配置。 其中, 上报的能力包括 CSI上报的 UE能力、 导频配置的 UE 能力、 支持的 CSI测量类型的能力、 缓存能力等。 在本申请中, 关注的是 CSI上报的能 力, UE100会向接入节点 200上报与至少一个时域单元支持的用于 CSI测量的导频的端 口 (port) 数相关的 CSI上报能力信息, 其中, 导频的概念可以包括参考信号 (Reference Signal, 简称为 RS) 、 同步信号块 (Synchronization Signal Block, 简称为 SSB) 等、 前 导等, 本申请后续以 RS 为导频代表进行描述。 接入节点 200在 CSI测量上报的相关配 置会根据该能力信息对 UE100进行配置, 包括资源的配置和上报的配置。 基于该能力信 息, 接入节点 200需要考虑 CSI测量的配置是否超出 UE的处理能力, 在 UE100该进行 上报时, 能否已经处理完相应的 CSI测量, 能够进行上报;在什么时间配置或触发 UE100 上报是合适的。
之后, 进入到 CSI测量阶段, 接入节点 200向 UE100发送导频信号进行信道测量和 干扰测量, UE100上报信道状态信息 CSI, 包括例如: 预编码矩阵指示(Precoding Matrix Indicator, 简称为 PMI) 、秩指示(Rank Indication, 简称为 RI)和信道质量指示(Channel Quality Indicator, 简称为 CQI) 等; 其中, UE100通过 PMI可以告诉接入节点 200当前 下行传输的最佳预编码矩阵。 通过 RI告诉接入节点 200当前下行传输的最佳层数。 CQI 表示在采用了建议的 RI和 PMI之后, 为确保下行数据接收的误码率不超过预定值, 可 用的调制编码方案。 CSI上报既可以以周期的方式上报给接入节点 200, 也可以以非周期 的形式上报, 两种方式的区别在于配置或触发报告的方式不同。
需要说明的是, 图 1 所示的仅是本申请所涉及的一种网络系统架构的示例, 本申请 并不局限于此。 类似的, 本申请还可以在正 EE802. i l的系统中应用, 通过站点 (Station, 简称为 STA) 向接入点 (Access Point, 简称为 AP) 上报自己的信道测量信息的上报能 力, 有效进行 STA信道测量上报的配置。 实施例一
网络中, UE与接入节点建立连接, 采用本实施例的方法进行 CSI上报能力的上报, 从而使接入节点获知真实的 UE的 CSI上报能力, 灵活进行 CSI测量和上报的配置。 本 实施例及后续实施例皆以 UE 与接入节点之间交互进行描述, 仅为示例性描述, 本申请 不限于此,在网络中接入节点管理下的传输接收点 TRP具备部分接入节点的相关功能时, 本申请还可以应用在 UE与 TRP交互进行 CSI上报能力的上报的场景下。 根据本申请的 实施例, 图 2 为本申请提供的一种终端设备能力的上报方法的第一个实施例的流程图, 为了便于方案理解, 在描述时, 本实施例及后续实施例皆以 UE 和接入节点双侧的行为 展开, 从交互多方的角度进行整体描述, 但绝非限定系统中改进在于交互各侧的步骤必 须合在一起执行, 本申请提出的技术方案, 在系统中每一侧均有改进。
该方法包括:
S 10K UE生成能力信息。
UE与接入节点建立连接后, 需要向接入节点上报自身所支持的能力的能力信息, 上 报的能力包括 CSI上报的 UE能力、 导频配置的 UE能力等。 在本申请中, 关注的是 CSI 上报的能力, CSI上报的能力是 UE的计算能力在涉及 CSI上报需求的一种能力体现。
S 102、 UE向接入节点发送 UE的能力信息。
其中, 该能力信息用于指示 UE的信道状态信息 CSI上报能力, 该能力信息与该 UE 至少一个时域单元 (unit) 支持的用于 CSI测量的导频 (如 RS) 的端口 (port)数相关联。 用于 CSI测量的导频 (如 RS) 的端口 (port) 数可以指, 发送用于 CSI测量的导频 (如 RS) 所用的端口数, 端口可以理解为逻辑上的虚拟天线, 端口是从接收者的角度定义的, 个端口对于接收者来说就认为是一个独立的天线信道, 端口的区分可以通过不同的时 频资源位置、 不同的码域拓展序列等进行区分, 通过不同的端口可以区分不同的信道。
该能力信息可以有一个或者至少两个, 如果针对不同的 CSI测量类型, 如不同的码 本类型、 不同的预编码矩阵指示 PMI类型、 不同的带宽部分 BWP 大小等。 可选的, 还 有不同的混合类型如: 不同的码本类型和不同的 PMI 类型、 不同的码本类型和不同的 BWP大小、 不同的 PMI类型和不同的 BWP大小、 不同的码本类型和不同的 PMI类型以 及不同的 BWP 大小等。 该至少两个能力信息可以分别指示针对不同 CSI测量类型下的 UE的 CSI上报能力; 如果该能力信息不针对不同的 CSI测量类型进行区分, 则可选的, UE的 CSI上报能力以特定类型 (如, 最大复杂度的类型、 最耗时的类型、 预设的指定类 型等) 下的上报能力确定, 所述能力信息指示特定类型下的 CSI上报能力。
其中, 用于 CSI测量的导频的端口数包括以下至少一项: 用于信道测量的导频的端 口数、 用于信道测量的导频的端口数和用于干扰测量的导频的端口数的和、 用于信道测 量的导频的端口数和用于干扰测量的导频的端口数的加权和, 可选的, 如果用于干扰测 量的导频的计算复杂度可能小于用于信道测量的导频的复杂度, 用于干扰测量的导频的 端口数的加权因子可以选择小于等于 1, 但此仅为本申请的示例, 本申请不限于此。
UE的 CSI上报能力可以通过至少一个时域单元支持的用于 CSI测量的导频的端口数 来体现, 可选的, 可以是至少一个时域单元最大支持的用于 CSI测量的导频的端口数, 也就是 UE 至少一个时域单元能够处理的最大计算量的体现; 或者根据特定考量, 根据 预定策略确定的至少一个时域单元支持的用于 CSI测量的导频的端口数, 如体现平均计 算能力的端口数、 或特定场景下能够处理的端口数。 其中, 导频的概念可以包括参考信 号 (Reference Signal, 简称为 RS) 、 同步信号块 (Synchronization Signal Block, 简称为 SSB) 等、 前导等, 本申请后续以 RS为导频代表进行描述。
UE的 CSI上报能力也可以通过支持用于 CSI测量的导频的预定端口数所需的时域单 元数 (即, 对所述预定端口数对应的计算量进行计算所需的时域单元数的信息) 来体现, 具体的, 比如预定端口数是 P (P大于等于 1) , 其中, 预定端口数可选的, 可以是预设 的 UE支持的可配置的最少端口数、 预设的 UE支持的可配置的最多端口数、按预定配置 标准确定的端口数。 计算完 P端口所需的时域单元数为 N (P大于等于 1) , 因此, P/N 就是每个时域单元支持的用于 CSI测量的导频的端口数, 可见, 计算用于 CSI测量的导 频的预定端口数所需的时域单元数, 是与至少一个时域单元支持的用于 CSI测量的导频 的端口数有间接的关联关系。 可选的, 计算用于 CSI测量的导频的预定端口数所需的时 域单元数, 可以是计算用于 CSI测量的导频的预定端口数所需的最少时域单元数, 即体 现 UE最快的处理速度; 或者根据特定考量, 根据预定策略确定的计算用于 CSI测量的 导频的预定端口数所需的时域单元数, 如体现平均计算速度的时域单元数、 或特定场景 下的处理速度对应的时域单元数。
需要说明的, 本申请不限于此两种 CSI能力的体现表示, 只要与至少一个时域单元 支持的用于 CSI测量的导频的端口数相关联的任何直接或间接的表示皆能用于本申请。
因此, 对应 CSI的能力指示, 所述能力信息包括至少一个时域单元支持的用于 CSI测量 的导频的端口数的信息, 也可以包括计算用于 CSI测量的导频的预定端口数所需的时域 单元数的信息。
对于时域单元的划分, 一个时域单元可以包括以下划分类型的至少一种: n个时域符 号 (symbol) 、 n 个小时隙 (mini-slot) 、 n 个时隙 (slot) 、 n 个子帧 (subframe) 、 n 个帧 (frame) , 或者 n个以其他形式定义的子时域单元; 其中, n大于等于 1。
所述能力信息,可以通过比特图 B itmap中的比特位来指示或指示字段的取值来指示。 例如, 如果能力信息是如上所述的至少一个时域单元支持的用于 CSI测量的导频的端口 数, 假设所有可能的 CSI上报能力潜在值个数为 P (例如 P为 32, 则所有可能的 CSI上 报能力潜在值个数为 32个, 即对应 1 port至 32port, 包含 1 port和 32port, 此仅为示例, 还可能是 1 port至 48port等) , 通过 Bitmap中的比特位来指示的方式可以是: Bitmap长 度为 P比特 (bit) , 以下示例中以 P为 32为例进行描述, 可以理解, 本申请不限于此, 1 port至 32port分别由 32 bit中的每一比特位指示,可将该比特位置 1或置 0来进行指示。 例如要上报的端口数是 M, 则 UE上报的 Bitmap中第 M位 (起始位置为 1) 置为 1 (或 0) 其他比特位置为 0 (或 1) 。 对于通过指示字段的取值来指示的情况, 可以通过长 度为 I1 I比特的指示字段, 通过该字段的不同取值来指示端口数。 同样, 如果能力 信息是如上所述的计算用于 CSI测量的导频的预定端口数所需的时域单元数, 假设所有 可能的 CSI上报能力潜在值个数为 N (同样, 例如 N为 16, 即所有可能的 CSI上报能力 潜在值个数为 16个, 例如计算 32port所需 lunit至 16unit) , 通过 Bitmap中的比特位来 指示的方式可以是: Bitmap长度为 N比特 (bit) , 假如要上报的时域单元数是 M (即计 算 32port需要 M个 unit) , 则 UE上报的 Bitmap中第 M位 (起始位置为 1) 置为 1 (或 0) 其他比 位置为 0 (或 1) 。 对于通过指示字段的取值来指示的情况, 可以通过长 度为 # 比特的指示字段, 通过该字段的不同取值来指示时域单元数。 可以理解的, 指示的形式不限于以上举例, 所有能实现对不同类型进行指示的方式都可用于本申请。

独立的字段进行串联, 相比于一个字段能指示多个值) , 每个数值对应的含义可以为: 不同码本类型、 不同 PMI类型、 不同 BWP大小、 前述类型的各种混合类型。
5203、 根据接收到的 UE上报的能力信息, 接入节点确定对 UE的 CSI测量的相关 配置。

实施例三
图 4 为本申请提供的一种终端设备能力的上报方法的第三个实施例的流程图。 本实 施例与实施例一或二的区别在于, 该实施例针对 CSI上报的 UE能力存在不同定义类型 的选择的情况下, 进行 UE 能力上报流程, 此外, 实施例二中的情况是能力信息中有多 个能力值的情况, 而本实施例中主要针对选择的对应各能力值的格式 /定义形式可选。 与 实施例一或二相同或类似的内容在本实施例中不再赞述。 该方法包括:
S30K 接入节点向 UE发送 CSI上报能力的定义类型选择指示信息。
对于网络中存在多种 CSI上报能力的定义类型时, UE与接入节点建立连接后, 是不 确定向接入节点上报哪种定义类型的 CSI上报能力的。 因此, 需要接入节点向 UE发送 CSI上报能力的定义类型选择指示信息,以告知 UE随后 CSI上报能力以哪种定义类型进 行确定和上报。
需要说明的是, 本实施例中, CSI 上报能力的定义类型选择指示信息所针对的 CSI 上报能力, 不一定是实施例一中所定义的方式, 还可以是针对其他定义的 CSI上报能力, 只要该 CSI上报能力存在多种定义类型, 均可通过本实施例的方式进行指示。
可选的, 针对如实施例一所述的 CSI上报能力的定义, 所述定义类型可以是针对其 中时域单元划分类型的不同而定义不同的 CSI上报能力, 例如, CSI上报能力可以与 n 个 symbol支持的用于 CSI测量的导频的端口数相关联、 与 n个 mini-slot支持的用于 CSI 测量的导频的端口数相关联、 与 n个 slot支持的用于 CSI测量的导频的端口数相关联、 与 n个 subframe支持的用于 CSI测量的导频的端口数相关联、 与 n个 frame支持的用于 CSI测量的导频的端口数相关联, 或者与 n个以其他形式定义的子时域单元支持的用于 CSI测量的导频的端口数相关联; 其中, n大于等于 1。 因此, 所述定义类型选择指示信 息, 可以通过定义类型索引来进行定义类型选择的指示, 还可以通过比特图 Bitmap中相 应的比特位进行指示, 例如, 时域单元的划分类型有 4种, Bitmap的长度可以为 4比特, 每一比特位对应一种类型 (如 n个 symbol、 n个 slot) , 通过将相应的比特位置 1或置 0, 来指示该定义类型中时域单元的划分对应哪种划分类型 (如以 n个 symbol划分还是以 n
个 slot划分) ; 所述定义类型选择指示信息, 可以通过指示字段的取值来进行指示, 例 如, 对于时域单元的划分类型有 4种, 指示字段可以为 2比特, 通过该字段的不同取值, 如 00、 01、 10、 11来分别指示对应的划分类型。 可以理解的, 指示的形式不限于以上举 例, 所有能实现对不同类型进行指示的方式都可用于本申请。
可选的, 针对如实施例一所述的 CSI上报能力的定义中至少一个时域单元支持的用 于 CSI测量的导频的端口数的情况下, 所述定义类型可以是针对 UE的计算能力分类的 不同而定义不同的 CSI上报能力, 例如, CSI上报能力可以与 UE是否具备针对 CSI测量 上报集的多个并行计算通道, 以及每个时域单元是否支持一个上报集的计算相关联, 可 以包括三种分类: 一、 UE不具备针对 CSI测量上报集的多个并行计算通道, 每个时域单 元支持一个上报集的计算; 二、 UE具备针对 CSI测量上报集的多个并行计算通道, 一个 并行计算通道对应一个上报集的计算; 三、 UE具备针对 CSI测量上报集的多个并行计算 通道, 多个并行计算通道对应一个上报集的并行计算。 因此, 同样, 所述定义类型选择 指示信息, 可以通过定义类型索引或比特图 Bitmap中相应的比特位进行指示或, 通过指 示字段的取值来进行指示, 具体方式类似, 在此不再贅述。 可以理解的, 指示的形式不 限于以上举例, 所有能实现对不同类型进行指示的方式都可用于本申请。
5302、 UE根据收到的所述 CSI上报能力的定义类型选择指示信息, 生成能力信息。 如果根据上面的示例, 定义类型选择指示信息指示时域单元的划分为以一个 slot 为 单位进行划分, 则根据每个 slot支持的用于 CSI测量的导频的 port数相关联的定义情况 生成待上报的能力信息。
如果根据上面的示例, 定义类型选择指示信息指示计算能力分类为以上第三种, 则 根据 UE具备针对 CSI测量上报集的多个并行计算通道, 一个并行计算通道对应一个上 报集的计算相关联的定义情况生成待上报的能力信息。
5303、 UE向接入节点发送 UE的能力信息。
其中, 该能力信息用于指示 UE的信道状态信息 CSI上报能力, 如果该能力信息与 UE 至少一个时域单元 (unit) 支持的用于 CSI测量的导频的端口 (port) 数相关联, 则 可具体参考实施一例的相关描述, 在此不再贅述。
对于 S302示例中三种计算能力分类, 如果是第一种和第三种, 可选的, 所述能力信 息包括计算用于 CSI测量导频的预定端口数所需的时域单元数的信息。 如果是第二种, 可选的, 所述能力信息包括计算用于 CSI测量导频的预定端口数所需的时域单元数的信 息和并行计算通道数。
5304、 根据接收到的 UE上报的能力信息, 接入节点确定对 UE的 CSI测量的相关 配置。
此步骤与 S 103类似, 在此不再贅述。
5305、 接入节点向 UE发送 CSI测量的相关配置信息。
UE根据接入节点发来的 CSI测量的相关配置信息, 进行配置, 根据该配置, 在后续 CSI测量时, 完成 CSI的测量并上报。
本申请实施例的一种终端设备能力的上报方法, 通过接入节点向 UE发送 CSI上报 能力的定义类型选择指示信息, 使得在系统中存在多种 CSI上报能力的定义类型时, UE 能有效上报 CSI上报能力。
实施例四
图 5 为本申请提供的一种终端设备能力的上报方法的第四个实施例的流程图。 本实 施例与实施例三的区别在于, 该实施例针对 CSI上报的 UE 能力存在不同定义类型的选 择的情况下, 由 UE 上报定义类型的选择指示, 与实施例三相同或类似的内容在本实施 例中不再贅述。 需要说明的是, 与实施例三类似, 本实施例中所针对的 CSI上报能力, 不一定是实施例一中所定义的方式,还可以是针对其他定义的 CSI上报能力,只要该 CSI 上报能力存在多种定义类型, 均可应用本实施例的方式。
该方法包括:
S40K UE生成能力信息。
对于网络中存在多种 CSI上报能力的定义类型时, UE与接入节点建立连接后, 待进 行能力上报时, 可以根据 UE选定的 CSI上报能力的定义类型生成能力信息。 比如, 对 于所述时域单元的划分类型, UE可以根据自身计算能力的强弱, 以处理中不同的时域单 元划分大小灵活地来体现自身的计算处理能力。
5402、 UE向接入节点发送 UE的能力信息。
关于能力信息的相关描述, 具体可参见实施例一至实施例三, 在此不再贅述。
5403、 UE向接入节点发送 UE选择的 CSI上报能力的定义类型选择指示信息。 针对网络中存在多种 CSI上报能力的定义类型, 可选的, UE可以通过能力信息的信 令格式的不同来指示接入节点 UE选定的定义类型; 可选的, UE可以通过定义类型选择 指示信息来告知接入节点 UE 选定的定义类型。 该定义类型选择指示信息可以与所述能 力信息一起发送或分开发送。
关于定义类型的划分举例和定义类型选择指示信息的指示方式举例, 皆可参见实施 例三的相关描述, 在此不再贅述。
需要说明的是, S402和 S403并非存在必然的先后顺序, 其仅是体现 UE向接入节点 发送两种信息, 如果定义类型选择指示信息可以通过 UE 上报能力信息的信令格式的不 同来指示, 则无需 S403 ; 如果定义类型选择指示信息与所述能力信息一起发送, 则 S402 和 S403为一个步骤。
5404、 根据接收到的 UE上报的能力信息, 接入节点确定对 UE的 CSI测量的相关 配置。
此步骤与 S 103类似, 在此不再贅述。
5405、 接入节点向 UE发送 CSI测量的相关配置信息。
UE根据接入节点发来的 CSI测量的相关配置信息, 进行配置, 根据该配置, 在后续 CSI测量时, 完成 CSI的测量并上报。
本申请实施例的一种终端设备能力的上报方法,通过 UE向接入节点指示 UE选择的 定义类型, 使得在系统中存在多种 CSI上报能力的定义类型时, 接入节点能有效获知 UE 的 CSI上报能力, 从而进行有效配置。 以上实施例侧重对 UE的 CSI上报能力进行上报的说明,接入节点获知了 UE的上报 能力后, 可以根据该能力进行 CSI测量的相关配置, 以下将给出接入节点进行 CSI测量 的相关配置的说明。
图 6给出了一种接入节点根据 UE的 CSI上报能力配置 UE周期或半持续 CSI上报
的配置方式的示意图。 其中, 有两种配置方式, 配置方式 1和配置方式 2。 假设 UE上报 的 CSI上报能力为每个 unit最大可支持 4个端口 (4ports) , unit以一个时隙 (slot) 进 行划分, 也就是 UE的 CSI上报能力为 UE每个 slot最大可支持 4ports。 因此接入节点对 UE进行 CSI测量和上报的配置时, 需考虑 UE每个 slot最大可支持 4ports, UE进行 CSI 上报时, 要完成相应的 CSI测量的计算量, 能够进行 CSI上报。
如图 6所示, 配置方式 1 中, 接入节点配置 UE周期或半持续进行 CSI上报, 每 4 个 slot单元进行一次 CSI上报, 接入节点在第一 slot单元 (slot O) 配置用于 CSI测量的 包含 8ports的信道测量导频集合 (Channel Measurement Reference Signal Set,简称为 CMR set) , 在第二 slot单元 (slot 1 ) 配置用于 CSI测量的包含 16ports的干扰测量导频集合 (Interference Measurement Reference Signal Set, 简称为 IMR set) 。 可见, UE完成信道 测量和干扰测量需要完成 8ports+16ports=24ports的计算量, 根据 UE的 CSI上报能力每 个 slot最大可支持 4ports, 那么 UE要完成 24ports的测量计算, 需要至少 6个 slot。 那么 如果接入节点如配置方式 1这样配置如上的 24ports的 CSI测量的计算量,那么就不能配 置 UE每 4个 slot进行一次 CSI上报 (如在第五个 slot单元 (slot4) ) , 这样 UE无法完 成测量进行上报。 因此配置 1的方式为不可用的配置。
如图 6所示, 配置方式 2中, 接入节点配置 UE周期或半持续进行 CSI上报, 同样 也是每 4个 slot单元进行一次 CSI上报。但接入节点配置在第一 slot单元配置包含 8ports 的 CMR set, 在第二 slot单元配置包含 8ports的 IMR set。 可见, UE完成信道测量和干 扰测量需要完成 8ports+8ports=16ports的计算量, 根据 UE的 CSI上报能力每个 slot最大 可支持 4ports, 那么 UE要完成 16ports的测量计算, 需要至少 4个 slot。 那么如果接入 节点如配置方式 2这样配置如上的 16ports的 CSI测量的计算量和上报周期 (每 4个 slot), 那么 UE能根据这样的配置完成相应测量进行上报。 因此配置 2的方式为可用的配置。
图 7给出了一种接入节点根据 UE的 CSI上报能力配置 UE非周期 CSI上报的配置 方式的示意图。 其中, 有两种配置方式, 配置方式 1和配置方式 2, 假设 UE上报的 CSI 上报能力为每个 unit最大可支持 16ports, unit以一个 slot进行划分, 也就是 UE的 CSI 上报能力为 UE每个 slot最大可支持 16portSc 因此接入节点对 UE进行 CSI测量和上报 的配置时, 需考虑 UE每个 slot最大可支持 16ports, UE进行 CSI上报时, 要完成相应的 CSI测量的计算量, 能够进行 CSI上报。
如图 7 所示, 配置方式 1 中, 接入节点配置 UE非周期上报的时间偏移量 (timing offset) , 该时间偏移量是接入节点发送 CSI触发的触发时域单元到 CSI上报的域间单元 的间隔, 所图 7所示, 该时间偏移量 Y被配置为 5slots。
对于 CSI测量, 可以基于各种因素的考虑 (如, 干扰的改变) 进行多次测量和上报 (如 CSI测量 1、 CSI测量 2) 。 对于 CSI测量 1, 配置 UE上报的上报集个数是 2个, 分别对应 CMR setl和 IMR setl、 CMR set2和 IMR set2。 接入节点在第一 slot单元 (slot 0)配置用于 CSI测量的包含 8ports的 CMR setl,在第二 slot单元 (slot 1 )配置包含 16ports 的 CMR set2, 在第四 slot单元 ( slot 3 ) 配置用于 CSI测量的包含 8ports的 IMR setl, 在 第五 slot单元 (slot 4) 配置包含 16ports的 IMR set2 ; 可见, UE要计算的 CSI测量 1的 总计算量为 8+16+8+16=48portSc
对于 CSI测量 2,配置 UE上报的上报集个数是 2个,分别对应 CMR setl和 IMR set3、 CMR set2和 IMR set4。在第七 slot单元 (slot 6)配置报含 8ports的 IMR set3 , 在第八 slot
单元 ( slot 7 ) 配置包含 16ports的 IMR set4。 可见, UE要计算的 CSI测量 2的总计算量 为 8 + 16+8 + 16=48ports 0
可见, 对于 CSI测量 1, UE完成 48ports的计算, 需要至少 48/16=3slots, 如果接入 节点配置在 slot 3进行 CSI测量 1的触发, 那么经过配置的时间偏移量 Y, 在 slot 8时, 经过 5slots的时间, UE能够完成 CSI1测量并进行上报。 因此, 对于 CSI测量的时间偏 移量和计算量的配置, 是可用的。 同样, 对于 CSI测量 2的时间偏移量和计算量的配置, 也是可用的。
但是, 如果对于 CSI测量 2, 接入节点配置在 slot 5进行 CSI测量 2的触发, 那么此 时 UE在进行 CSI测量 1的计算, 还没有计算完, 那么此时超出 UE的能力, 接入节点不 能配置在该时刻触发。 因此, 该配置不可用。
如图 7所示, 配置方式 2中, 其他不变, 如果对于 CSI测量 2, 接入节点配置在 slot 6进行 CSI测量 2的触发, 那么此时 UE已经空间, 基站可以触发新的 CSI上报, 接入节 点可以配置在该时刻触发。 该配置可用。
图 8给出了另一种接入节点根据 UE的 CSI上报能力配置 UE非周期 CSI上报的配 置方式的示意图。 其中, 有两种配置方式, 配置方式 1 和配置方式 2, 假设 UE上报的 CSI上报能力为每个 unit最大可支持 16ports , unit以一个 slot进行划分, 也就是 UE的 CSI上报能力为 UE每个 slot最大可支持 16ports。因此接入节点对 UE进行 CSI测量和上 报的配置时, 需考虑 UE每个 slot最大可支持 16ports, UE进行 CSI上报时, 要完成相应 的 CSI测量的计算量, 能够进行 CSI上报。
如图 8所示,配置方式 1 中,接入节点配置 UE非周期上报的时间偏移量仍为 5slotSc 对于 CSI测量 1, 配置 UE上报的上报集个数是 2个, 分别对应 CMR setl和 IMR setl、 CMR set2和 IMR set2,接入节点在第一 slot单元 ( slot 0)配置用于 CSI测量的包含 8ports 的 CMR setl , 在第二 slot单元 ( slot 1 ) 配置包含 16ports的 CMR set2, 在第六 slot单元 ( slot 5 ) 配置用于 CSI测量的包含 8ports的 IMR setl , 在和第七 slot单元 ( slot 6) 分别 发送包含 16ports 的 IMR setl : 可见, UE 要计算的 CSI 测量 1 的总计算量为 8+16+8+16=48portSo
对于 CSI测量 2,配置 UE上报的上报集个数是 2个,分别对应 CMR setl和 IMR set3、 CMR set2和 IMR set4。 在第七 slot单元 ( slot 6) 发包含 8ports的 CMR set3 , 在第八 slot 单元 ( slot 7 ) 发包含 16ports的 CMR set4。 可见, UE要计算的 CSI测量 2的总计算量为 8+16+8+16=48portSo
可见, 对于 CSI测量 1, UE完成 48ports的计算, 需要至少 48/16=3slots。 但是, 需 要说明的, 除了总的计算时间, 接入节点配置时还需要考虑下发 CMR set和 IMR set的 时间和 UE上报时间之前的关系。 例如, 如果按照配置方式 1所示, 如果接入节点在 slot 1结束时触发 CSI测量 1的上报, 经过预置的时间偏移量, UE应该在 slot 6结束时进行 上报, 而由于 IMR setl ( 8ports ) 和 IMR set2 ( 16ports) 分别在 slot 5和 slot 6才下发, 那么在 slot 6时, UE还没有空闲, 还得处理干扰测量集的计算, 所以接入节点不能配置 在 slot 6触发 CSI测量 2的上报, 至少得在 slot 6结束后, UE处理完 CSI测量 1的计算, 才能进行 CSI测量 2的触发。 另外, 还需要说明, 如果 IMR setl和 IMR set2分别在 slot 5 和 slot 6才下发, UE需要在 slot 6结束时进行上报, 如果 IMR setl和 IMR set2的端口数 之和, 超过 UE在两个 unit所支持的端口数, 即 32ports, 那么 UE在 slot 6也无法完成配
置的计算量, 无法进行上报。
如图 8所示, 配置方式 2中, 其他不变, 如果 IMR set2的端口数变为 8ports, 并且 在 slot 5进行 CSI测量 2的触发, 那么在 slot 5和 slot6, UE各有剩余 8ports的计算能力, 虽然此时 (slot 5和 slot6) 还未收到配置的 IMR set3和 IMR set4, 但基站可以触发新的 CSI上报, UE可先对 CSI测量 2中已知的 CMR setl (8ports) 进行计算。 因此, 接入节 点可以配置在该时刻 (slot 5) 触发 CSI测量 2, 该配置可用。 可以理解的, 该配置方式 中, UE是支持并行处理的, 当有计算能力富余时, UE可以并行进行计算。 对于 UE支 持并行处理的, 将视为具有用于 CSI上报的更强的 UE能力。 如果在 CSI上报之前每个 时域单元的导频端口的平均数量不大于 UE能力, 则可以配置一个或多个上报集。
需要说明的, 以上配置方式说明, 具体针对 UE的 CSI上报能力为每个时域单元最 大支持的用于 CSI测量的导频的端口数的情况, 其仅为示例性说明, 给出针对 UE的 CSI 上报能力如何进行配置的说明, 不构成对本申请的限制, 针对 UE的 CSI上报能力的不 同定义情况, 遵循以上示例的配置逻辑, 接入节点对 UE的 CSI测量和上报的配置, 需 使得不超出 UE的 CSI上报能力, 使得 UE能够完成 CSI测量和上报。 上述主要从系统各实体之间交互进行并行传输控制的流程角度对本申请实施例提供 的方案进行了介绍。 可以理解的是, 各实体, 为了实现上述功能, 其包含了执行各个功 能相应的硬件结构和 /或软件模块。 本领域技术人员应该很容易意识到, 结合本文中所公 开的实施例描述的各示例的单元及算法步骤, 本申请能够以硬件或硬件和计算机软件的 结合形式来实现。 某个功能究竟以硬件还是计算机软件驱动硬件的方式来执行, 取决于 技术方案的特定应用和设计约束条件。 专业技术人员可以对每个特定的应用来使用不同 方法来实现所描述的功能, 但是这种实现不应认为超出本申请的范围。
本申请实施例可以根据上述方法示例对 UE、 接入节点进行功能模块的划分, 例如, 可以对应各个功能划分各个功能模块, 也可以将两个或两个以上的功能集成在一个处理 模块中。 上述集成的模块既可以采用硬件的形式实现, 也可以采用软件功能模块的形式 实现。 需要说明的是, 本申请实施例中对模块的划分是示意性的, 仅仅为一种逻辑功能 划分, 实际实现时可以有另外的划分方式。 下面以采用对应各个功能划分各个功能模块 为例进行说明。
本申请实施例还提供了一种终端设备。 该终端设备可以用于执行图 2 -图 5任一附图 中 UE所执行的步骤。 图 9示出了一种简化的终端设备结构示意图。 便于理解和图示方 便, 图 9中, 终端设备以手机作为例子。 如图 9所示, 终端设备 90包括处理器、 存储器、 射频电路、 天线以及输入输出装置。 处理器主要用于对通信协议以及通信数据进行处理, 以及对终端设备 90进行控制, 执行软件程序, 处理软件程序的数据等。 存储器主要用于 存储软件程序和数据。 射频电路主要用于基带信号与射频信号的转换以及对射频信号的 处理。 天线主要用于收发电磁波形式的射频信号。 输入输出装置, 例如触摸屏、 显示屏, 键盘等主要用于接收用户输入的数据以及对用户输出数据。 需要说明的是, 有些种类的 终端设备 90可以不具有输入输出装置。 其中, 存储器和处理器可以是集成在一起的, 也 可以是独立设置的; 此外, 射频电路和处理器可以是集成在一起的, 也可以是独立设置 的。
当需要发送数据时, 处理器对待发送的数据进行基带处理后, 输出基带信号至射频
电路, 射频电路将基带信号进行射频处理后将射频信号通过天线以电磁波的形式向外发 送。 当有数据发送到终端设备 90时, 射频电路通过天线接收到射频信号, 将射频信号转 换为基带信号, 并将基带信号输出至处理器, 处理器将基带信号转换为数据并对该数据 进行处理。 为便于说明, 图 9 中仅示出了一个存储器和处理器。 在实际的终端设备产品 中, 可以存在一个或多个处理器和一个或多个存储器。 存储器也可以称为存储介质或者 存储设备等。 存储器可以是独立于处理器设置, 也可以是与处理器集成在一起, 本申请 实施例对此不做限制。

Actually, for each reporting setting, the real UE capability for CSI reporting depends on how much workload UE can afford for calculating CSI info based on the CSI-RS resources configured in resource settings linked with the reporting setting. The total number of CSI-RS ports in each unit UE can afford can reflect the UE capability for CSI reporting. UE capability for CSI reporting can be defined as the maximum number of CSI-RS ports for each unit UE afford for update CSI. For UE supports processing in parallel would have a large UE capability for CSI reporting. One or more reporting setting can be configured if the average number of CSI-RS ports for each unit before CSI reporting is no larger than the UE capability.
Then we can the following proposal:
Proposal XX: UE capability for CSI reporting can be defined as the maximum number of CSI-RS ports for each unit UE afford for update CSI.
可见, 在提案中给出, UE在每个 unit中能够承载的 CSI-RS端口的总数可以反映用 于 CSI上报的 UE能力。 用于 CSI上报的 UE能力可以被定义为 UE为更新 CSI提供的 每个 unit的 CSI-RS端口的最大数量。 对于 UE支持并行处理的, 将具有用于 CSI上报 的更大的 UE能力。 如果在 CSI上报之前每个单元的 CSI-RS端口的平均数量不大于 UE 能力, 则可以配置一个或多个上报集。
最后, 优选的, 在提案中的优选方案为: 用于 CSI上报的 UE能力可以被定义为 UE 为更新 CSI支持的每个 unit的 CSI-RS端口的最大数量。 尽管在此结合各实施例对本申请进行了描述, 然而, 在实施所要求保护的本申请过
