技术领域 Technical field
本发明涉及通信技术领域， 尤其涉及一种周期 CSI上 ·ί艮方法及终端。 背景技术  The present invention relates to the field of communications technologies, and in particular, to a periodic CSI method and a terminal. Background technique
LTE-A ( Long-Term Evolution- Advanced, 长期演进增强） 系统釆用同频组网， 在大幅 度提高频谱利用率的同时， 也会使小区边缘的 UE ( User Equipment, 用户设备； 也称为终 端）信号严重衰落， 并受到较高的来自其他小区的千扰。 若不对信号衰落和千扰问题加以 处理， 将会严重影响小区边缘终端的数据传输性能。 CoMP ( Coordinated Multiple Point, 多点协作）技术通过引入多小区之间的信息交互和联合传输， 不仅可以提高信号盾量， 也 可以降低小区间千扰， 从而可以大幅度提高小区边缘终端的数据传输性能。  LTE-A (Long-Term Evolution-Advanced) system uses the same-frequency networking to greatly improve the spectrum utilization rate, and also enables the UE at the cell edge (User Equipment; also called The terminal) signal is seriously fading and is subject to higher interference from other cells. If the signal fading and interference problems are not handled, the data transmission performance of the cell edge terminal will be seriously affected. The CoMP (Coordinated Multiple Point) technology introduces information exchange and joint transmission between multiple cells, which not only improves the signal shield but also reduces inter-cell interference, thereby greatly improving the data transmission of the cell edge terminal. performance.
目前的多点协作传输方案大致可以分为： DPS ( Dynamic Point Selection, 动态传输点 选择）， CBF ( Coordinated BeamForming, 协作波束赋形）， JT ( Joint Transmission, 联合传 输）， 或者是以上 3类传输方案的混合方案。 比如， DPS和 CBF相结合， 主传输点通过动 态选择确定， 与主传输点外的协作传输点之间通过联合调度实现协作波束赋形等。 同时， 也可以通过在某些时频资源上让某些传输点空出不发信号， 从而减少对其他传输点的千 扰， 实现灵活的频域千扰协调， 此类技术称为 DB ( Dynamic Blanking, 动态空白）。 在实 际系统中， 一个传输模式可能包括多种传输方案， 支持各类传输方案之间的模式切换。 为 了更好地保证传输性能和系统稳定性， 支持 CoMP传输的传输模式中往往需要支持向单点 传输的切换。  The current multi-point coordinated transmission scheme can be roughly divided into: DPS (Dynamic Point Selection), CBF (Coordinated Beam Forming), JT (Joint Transmission), or the above three types of transmission. A hybrid solution for the program. For example, in combination with DPS and CBF, the primary transmission point is determined by dynamic selection, and cooperative beamforming is achieved by joint scheduling with coordinated transmission points outside the primary transmission point. At the same time, it is also possible to reduce the interference to other transmission points by allowing some transmission points to be vacated on certain time-frequency resources, thereby achieving flexible frequency-domain interference coordination. This type of technology is called DB (Dynamic). Blanking, dynamic blank). In an actual system, a transmission mode may include multiple transmission schemes to support mode switching between various transmission schemes. In order to better ensure transmission performance and system stability, transmission modes supporting CoMP transmission often need to support switching to single-point transmission.
系统通过配置不同的 CSI-RS ( Channel State Information-Reference Signal, 信道状态信 息参考信号）使得终端可以测量各个传输点的下行信道， 每个传输点对应于一个 CSI-RS 资源。 值得注意的是， 传输点可以是一个物理的传输点， 而可以是一个虚拟的传输点， 每 个虚拟的传输点由一个或多个物理的传输点构成。  The system can configure different CSI-RS (Channel State Information-Reference Signals) so that the terminal can measure the downlink channels of each transmission point. Each transmission point corresponds to one CSI-RS resource. It is worth noting that the transmission point can be a physical transmission point, but can be a virtual transmission point, and each virtual transmission point is composed of one or more physical transmission points.
实现下行信道测量后， 根据传输方案所需要的 CSI ( Channel State Information, 信道状 态信息）进行信息反馈。 各类传输方案需要相应的信道状态信息支持。 比如， DPS传输方 案需要多个传输点的信道状态信息， 或者某一个传输点的信道状态信息和该传输点所对应 的 CSI-RS索引信息。 结合 DB技术的 DPS传输方案需要多种千扰假设情况下的信道盾量 信息。 JT传输方案需要多个传输点反馈相同 Rank (秩） 的信道状态信息等。 在现有的 LTE ( Long-Term Evolution, 长期演进） 系统中， 支持两类 CSI反馈方式。 即， 基于 PUCCH ( Physical Uplink Control Channel, 物理上行控制信道） 的周期 CSI反馈 和基于 PUSCH ( Physical Uplink Shared Channel, 物理上行共享信道） 的非周期 CSI反馈。 After the downlink channel measurement is implemented, information feedback is performed according to CSI (Channel State Information) required by the transmission scheme. Various transmission schemes require corresponding channel state information support. For example, the DPS transmission scheme requires channel state information of multiple transmission points, or channel state information of a certain transmission point and CSI-RS index information corresponding to the transmission point. The DPS transmission scheme combined with DB technology requires a variety of channel shields under the assumption of interference Information. The JT transmission scheme requires multiple transmission points to feed back channel state information of the same Rank (rank) and the like. In the existing LTE (Long-Term Evolution) system, two types of CSI feedback modes are supported. That is, periodic CSI feedback based on PUCCH (Physical Uplink Control Channel) and aperiodic CSI feedback based on PUSCH (Physical Uplink Shared Channel).

为了支持 CoMP传输。 终端在进行周期 CSI上报时， 对不同传输点或者千扰假设的 CSI分别配置上报周期，按照各自的上报周期独立上报。如果不同传输点或千扰假设的 CSI 在同一个时刻上报，则其使用的 PUCCH资源将会发生冲突。现有的解决方案是,在 PUCCH 所能承受的最大负载范围内 , 将这些冲突的 CSI按照 reporting type优先级进行合并传输。 如果所有 CSI合并后的负载大于 PUCCH所能承受的最大负载， 则不对 reporting type优先 级较低的 CSI进行反馈。 在一个 PUCCH中允许合并传输的 CSI负载的最大比特数， 称为 比特门限。  In order to support CoMP transmission. When reporting the periodic CSI, the terminal configures the reporting period for the CSIs of different transmission points or the interference assumptions, and independently reports them according to their respective reporting periods. If the CSIs of different transmission points or interference assumptions are reported at the same time, the PUCCH resources used by them will collide. The existing solution is to combine these conflicting CSIs according to the reporting type priority within the maximum load range that the PUCCH can bear. If the combined load of all CSIs is greater than the maximum load that the PUCCH can bear, the CSI with lower reporting type priority is not fed back. The maximum number of bits of the CSI payload allowed to be combined in a PUCCH, called the bit threshold.
现有技术中，比特门限为 PUCCH所能承受的最大负载。但是合并传输的不同周期 CSI 信息的解调门限和传输性能需求是不同的。 如果对不同周期 CSI信息都按照该 PUCCH所 能承载的最大比特数进行合并， 则无法满足一些准确性要求较高的周期 CSI信息的传输性 能需求， 从而导致基站可能无法获得准确的周期 CSI信息。 发明内容  In the prior art, the bit threshold is the maximum load that the PUCCH can withstand. However, the demodulation threshold and transmission performance requirements of CSI information for different periods of combined transmission are different. If the CSI information of different periods is combined according to the maximum number of bits that can be carried by the PUCCH, the transmission performance requirement of the periodic CSI information with high accuracy requirements cannot be met, and the base station may not be able to obtain accurate periodic CSI information. Summary of the invention

本发明实施例提供一种周期 CSI上 ·ί艮方法及终端。 当有多个（至少两个）周期 CSI信 息需要在同一上报时刻上报时， 即多个周期 CSI信息在同一上报时刻发生冲突， UE根据 上述冲突的周期 CSI信息来确定周期 CSI信息合并的比特门限； 根据预定的优先级规则对 发生冲突的周期 CSI信息排序； 进而在该比特门限的范围内， 按照发生冲突的周期 CSI信 息的优先级降序选择其中的部分周期 CSI信息进行合并上报。 确定的周期 CSI信息合并的 比特门限是根据冲突的周期 CSI信息确定的， 在保证合并传输的周期 CSI信息能满足传输 要求的前提下， 尽可能多的上报周期 CSI信息。 Embodiments of the present invention provide a periodic CSI method and a terminal. When there are multiple (at least two) periodic CSI information that need to be reported at the same reporting time, that is, multiple periodic CSI information collides at the same reporting time, the UE determines the bit threshold of the periodic CSI information combining according to the conflicting periodic CSI information. And sorting the periodic CSI information of the conflict according to the predetermined priority rule; and further, in the range of the bit threshold, selecting the partial periodic CSI information according to the priority descending order of the conflicting periodic CSI information for the combined reporting. The determined bit threshold of the combined CSI information is determined according to the conflicting periodic CSI information, and the CSI information can satisfy the transmission in the period of ensuring the combined transmission. On the premise of the request, report the periodic CSI information as much as possible.
其中， 多个周期 CSI信息在同一上报时刻合并上报是指， 多个周期 CSI信息在同一子 帧中的 PUCCH合并上 4艮。  The multiple periodic CSI information is combined and reported at the same reporting time, that is, the multiple periodic CSI information is merged in the PUCCH in the same subframe.
下面将结合附图， 对本发明实施例进行详细说明。  The embodiments of the present invention will be described in detail below with reference to the accompanying drawings.
如果有至少两个周期 CSI信息需要在同一上报时刻上报， 即至少两个周期 CSI信息在 同一上报时刻发生冲突， 则本发明实施例提供的一种周期 CSI上报方法， 其实现方式如图 1所示， 具体包括如下操作：  If there are at least two periodic CSI information that need to be reported at the same reporting time, that is, at least two periodic CSI information conflicts at the same reporting time, the periodic CSI reporting method provided by the embodiment of the present invention is implemented as shown in FIG. 1 . The indication includes the following operations:
步骤 100、UE根据上述发生冲突的周期 CSI信息，确定周期 CSI信息合并的比特门限。 步骤 110、 UE # ^据预定的优先级规则， 对发生冲突的周期 CSI信息排序。  Step 100: The UE determines a bit threshold for combining the periodic CSI information according to the periodic CSI information of the collision. Step 110: The UE #^ sorts the CSI information of the conflicting period according to a predetermined priority rule.
步骤 120、 在上述周期 CSI信息合并的比特门限的范围内， UE按照发生冲突的周期 Step 120: The UE follows the period in which the collision occurs within the range of the bit threshold of the period CSI information combination.
CSI信息的优先级降序从上述发生冲突的周期 CSI信息中选择至少一个周期 CSI信息。 The priority descending order of the CSI information selects at least one period CSI information from the above-mentioned conflicting period CSI information.
具体的， UE按照发生冲突的周期 CSI信息的优先级降序，从上述发生冲突的周期 CSI 信息中选择周期 CSI信息合并的比特门限范围内最多的周期 CSI信息。  Specifically, the UE selects the most periodic CSI information in the range of the bit threshold of the combined CSI information from the conflicting periodic CSI information according to the priority descending order of the conflicting CSI information.
例如，按照优先级降序， 前 N个周期 CSI信息的总大小超过周期 CSI信息合并的比特 门限， 则选择前 N-1个周期 CSI信息。  For example, in descending order of priority, the total size of the first N periods of CSI information exceeds the bit threshold of the periodic CSI information combination, and the first N-1 period CSI information is selected.
步骤 130、 UE将选择的周期 CSI信息在上述的上报时刻上报。  Step 130: The UE reports the selected period CSI information at the reporting time.
其中， 如果选择的周期 CSI信息超过一个， 则 UE将选择的周期 CSI信息按照优先级 降序合并后在上述的上报时刻进行上报。 合并后的周期 CSI信息的长度不大于周期 CSI信 息合并的比特门限。  If the selected period CSI information exceeds one, the UE combines the selected periodic CSI information in descending order of priority and reports the result at the reporting time. The combined period CSI information is not longer than the bit threshold of the periodic CSI information merge.
本发明实施例中， 通过 UE与基站侧预先的约定， 或者基站侧对 UE的配置， 或者高 层信令指示等方式， 在 UE侧预置有多个比特门限以及比特门限的确定规则。 相应的， UE 才艮据上述发生冲突的周期 CSI信息， 确定周期 CSI信息合并的比特门限的具体实现方式有 很多种， 下面例举几种。  In the embodiment of the present invention, a plurality of bit thresholds and bit threshold determination rules are preset on the UE side by using a pre-agreed agreement between the UE and the base station, or a configuration of the UE by the base station or a high-level signaling indication. Correspondingly, the UE can determine the specific implementation manner of the bit threshold of the periodic CSI information combining according to the periodic CSI information of the collision, and the following are exemplified.
一、 UE侧预置有第一比特门限和第二比特门限， 并预置有相应的比特门限的确定规 则如下： 如果冲突的周期 CSI信息中包含 RI信息， 则使用第一比特门限； 如果冲突的周 期 CSI信息中不包含 RI信息， 则使用第二比特门限。 其中， 第一比特门限小于第二比特 门限， 第一比特门限和第二比特门限的值可以根据系统实际需求设定， 本发明实施例不作 限定。 作为举例而非限定， 可以根据 RI信息的传输性能需求设置第一比特门限的值， 根 据 PUCCH所能承载的最大比特数确定第二比特门限。  First, the UE side presets the first bit threshold and the second bit threshold, and presets the corresponding bit threshold to determine the following rules: If the conflicting periodic CSI information includes RI information, the first bit threshold is used; If the RI information is not included in the periodic CSI information, the second bit threshold is used. The first bit threshold is smaller than the second bit threshold, and the values of the first bit threshold and the second bit threshold may be set according to actual requirements of the system, which is not limited in the embodiment of the present invention. By way of example and not limitation, the value of the first bit threshold may be set according to the transmission performance requirement of the RI information, and the second bit threshold is determined according to the maximum number of bits that the PUCCH can carry.
UE根据发生冲突的周期 CSI信息中是否包含 RI信息确定周期 CSI信息合并的比特门 限。 具体地： UE判断上述发生冲突的周期 CSI信息中是否包含 RI信息； The UE determines a bit threshold for combining the periodic CSI information according to whether the RI information is included in the CSI information of the period in which the collision occurs. specifically: Determining, by the UE, whether the RI information is included in the periodic CSI information of the conflict;
如果包含 RI信息， UE确定第一比特门限为周期 CSI信息合并的比特门限； 如果不包含 RI信息， UE确定第二比特门限为周期 SCI信息合并的比特门限。  If the RI information is included, the UE determines that the first bit threshold is a bit threshold for combining the periodic CSI information; if the RI information is not included, the UE determines that the second bit threshold is a bit threshold for combining the periodic SCI information.
二、 UE侧预置有多个比特门限， 每个比特门限对应不同的 reporting type优先级， 预 置的比特门限的确定规则为： 按照比特门限与 reporting type优先级之间的对应关系， 确定 周期 CSI信息合并的比特门限。 UE根据发生冲突的周期 CSI信息中各个周期 CSI信息的 reporting type的优先级， 确定周期 CSI信息合并的比特门限。 举例说明其实现方式：  2. The UE side presets multiple bit thresholds, and each bit threshold corresponds to a different reporting type priority. The preset bit threshold is determined according to the correspondence between the bit threshold and the reporting type priority. The bit threshold for the CSI information merge. The UE determines the bit threshold of the periodic CSI information combining according to the priority of the reporting type of the CSI information in each period of the CSI information in which the collision occurs. Give an example of how it is implemented:
UE侧预置的比特门限， 以及每个比特门限对应的不同的 reporting type优先级如下： 根据 UE侧与基站侧的约定， 或者基站侧的配置， 或者高层信令指示， reporting type 1、 la、 2、 2a、 2b、 2c、 3、 4、 5、和 6被分为三个 reporting type优先级等级。其中，最高 reporting type优先级中包括： reporting type 3, 5, 6, 和 2a,次高 reporting type优先级中包括： reporting type 2, 2b, 2c, 和 4。 最低 reporting type优先级中包括 reporting type 1和 la。  The bit threshold preset on the UE side, and the different reporting type priority corresponding to each bit threshold are as follows: According to the agreement between the UE side and the base station side, or the configuration on the base station side, or the high layer signaling indication, reporting type 1, la, 2, 2a, 2b, 2c, 3, 4, 5, and 6 are divided into three reporting type priority levels. Among them, the highest reporting type priority includes: reporting type 3, 5, 6, and 2a, and the second highest reporting type priority includes: reporting type 2, 2b, 2c, and 4. The lowest reporting type priority includes reporting type 1 and la.
最高 reporting type优先级对应比特门限 A,次高 reporting type优先级对应比特门限 B , 最低 reporting type优先级对应比特门限 C。  The highest reporting type priority corresponds to the bit threshold A, the second highest reporting type priority corresponds to the bit threshold B, and the lowest reporting type priority corresponds to the bit threshold C.
确定周期 CSI信息合并的比特门限具体包括：  Determining the period The bit threshold of the CSI information combination specifically includes:
如果发生冲突的周期 CSI信息中有周期 CSI信息的 reporting type 为最高优先级的 reporting type, 则 UE确定比特门限 A为周期 CSI信息合并的比特门限。  If the reporting type of the periodic CSI information in the CSI information is the highest priority reporting type, the UE determines that the bit threshold A is the bit threshold of the periodic CSI information combining.
如果冲突的周期 CSI信息中没有周期 CSI信息的 reporting type 为最高优先级的 reporting type, 但有周期 CSI信息的 reporting type为次高优先级的 reporting type, 则 UE 确定比特门限 B为周期 CSI信息合并的比特门限。  If the reporting type of the periodic CSI information does not have the reporting type of the highest priority, but the reporting type of the periodic CSI information is the next highest priority reporting type, the UE determines that the bit threshold B is a periodic CSI information merge. Bit threshold.
如果冲突的周期 CSI信息中各个周期 CSI信息的 reporting type 均为最低优先级的 reporting type, UE确定比特门限 C为周期 CSI信息合并的比特门限。  If the reporting type of the CSI information in each period of the CSI information is the lowest priority reporting type, the UE determines that the bit threshold C is the bit threshold of the periodic CSI information combining.
三、 UE侧预置有第三比特门限和第四比特门限， 并预置有相应的比特门限的确定规 则如下： 如果冲突的周期 CSI信息中有主传输点对应的周期 CSI信息， 则对应第三比特门 限。如果冲突的周期 CSI信息中没有主传输点对应的周期 CSI信息，则对应第四比特门限。 其中， 第三比特门限小于第四比特门限， 第三比特门限和第四比特门限的值可以根据系统 实际需求设定， 本发明不作限定。 作为举例而非限定， 可以根据主传输点对应的周期 CSI 信息的传输性能需求设置第三比特门限的值， 根据 PUCCH所能承载的最大比特数确定第 四比特门限。  3. The UE side presets the third bit threshold and the fourth bit threshold, and presets the corresponding bit threshold to determine the following rules: If the periodic CSI information of the conflict has the periodic CSI information corresponding to the primary transmission point, the corresponding Three-bit threshold. If there is no periodic CSI information corresponding to the primary transmission point in the CSI information of the collision period, the fourth bit threshold is corresponding. The third bit threshold is smaller than the fourth bit threshold, and the values of the third bit threshold and the fourth bit threshold may be set according to actual requirements of the system, which is not limited by the present invention. By way of example and not limitation, the value of the third bit threshold may be set according to the transmission performance requirement of the periodic CSI information corresponding to the primary transmission point, and the fourth bit threshold is determined according to the maximum number of bits that the PUCCH can carry.
UE根据发生冲突的周期 CSI信息对应的传输点，确定周期 CSI信息合并的比特门限。 具体地： UE判断发生冲突的 CSI信息中是否有主传输点对应的周期 CSI信息； 如果有， UE确定第三比特门限为周期 CSI信息合并的比特门限； The UE determines a bit threshold for combining the periodic CSI information according to the transmission point corresponding to the period CSI information in which the collision occurs. specifically: The UE determines whether there is periodic CSI information corresponding to the primary transmission point in the CSI information that conflicts; if yes, the UE determines that the third bit threshold is a bit threshold of the periodic CSI information combination;
如果没有， UE确定第四比特门限为周期 CSI信息合并的比特门限。  If not, the UE determines that the fourth bit threshold is a bit threshold for the periodic CSI information combining.
四、 UE侧预置有第五比特门限和第六比特门限， 并预置有相应的比特门限的确定规 则如下： 如果冲突的周期 CSI信息中有该 UE的服务小区对应的周期 CSI信息， 则对应第 五比特门限。 如果冲突的周期 CSI信息中没有该 UE的服务小区对应的周期 CSI信息， 则 对应第六比特门限。 其中， 第五比特门限小于第六比特门限， 第五比特门限和第六比特门 限的值可以根据系统实际需求设定，本发明不作限定。作为举例而非限定，可以根据该 UE 的服务小区对应的周期 CSI信息的传输性能需求设置第五比特门限的值， 根据 PUCCH所 能承载的最大比特数确定第六比特门限。  The UE side is preset with a fifth bit threshold and a sixth bit threshold, and the rule for determining the corresponding bit threshold is as follows: If the periodic CSI information of the conflict has the periodic CSI information corresponding to the serving cell of the UE, Corresponds to the fifth bit threshold. If there is no periodic CSI information corresponding to the serving cell of the UE in the CSI information of the collision, the sixth bit threshold is corresponding. The fifth bit threshold is smaller than the sixth bit threshold, and the values of the fifth bit threshold and the sixth bit threshold may be set according to actual requirements of the system, which is not limited in the present invention. By way of example and not limitation, the value of the fifth bit threshold may be set according to the transmission performance requirement of the periodic CSI information corresponding to the serving cell of the UE, and the sixth bit threshold is determined according to the maximum number of bits that the PUCCH can carry.
UE根据发生冲突的周期 CSI信息对应的服务小区， 确定周期 CSI信息合并的比特门 限。 具体地：  The UE determines a bit threshold for combining the periodic CSI information according to the serving cell corresponding to the CSI information of the period in which the collision occurs. specifically:
UE判断冲突的 CSI信息中是否有该 UE的服务小区对应的周期 CSI信息；  The UE determines whether there is periodic CSI information corresponding to the serving cell of the UE in the conflicting CSI information;
如果有， UE确定第五比特门限为周期 CSI信息合并的比特门限；  If yes, the UE determines that the fifth bit threshold is a bit threshold for combining the periodic CSI information;
如果没有， UE确定第六比特门限为周期 CSI信息合并的比特门限。  If not, the UE determines the sixth bit threshold as the bit threshold for the periodic CSI information combining.
五、 UE侧预置有第七比特门限和第八比特门限， 并预置有相应的比特门限的确定规 则如下： 如果发生冲突的周期 CSI信息中有主载波对应的周期 CSI信息， 则对应第七比特 门限。如果冲突的周期 CSI信息中没有主载波对应的周期 CSI信息，则对应第八比特门限。 其中， 第七比特门限小于第八比特门限， 第七比特门限和第八比特门限的值可以根据系统 实际需求设定， 本发明不作限定。 作为举例而非限定， 可以才 居主载波对应的周期 CSI信 息的传输性能需求设置第七比特门限的值， 根据 PUCCH所能承载的最大比特数确定第八 比特门限。  5. The UE side presets the seventh bit threshold and the eighth bit threshold, and presets the corresponding bit threshold to determine the following rules: If there is a periodic CSI information corresponding to the primary carrier in the CSI information of the conflicting period, the corresponding Seven-bit threshold. If there is no periodic CSI information corresponding to the primary carrier in the CSI information of the conflicting period, the eighth bit threshold is corresponding. The seventh bit threshold is less than the eighth bit threshold, and the values of the seventh bit threshold and the eighth bit threshold may be set according to actual requirements of the system, which is not limited by the present invention. By way of example and not limitation, the value of the seventh bit threshold may be set in the transmission performance requirement of the periodic CSI information corresponding to the primary carrier, and the eighth bit threshold is determined according to the maximum number of bits that the PUCCH can carry.
UE 据发生冲突的周期 CSI信息对应的载波确定周期 CSI信息合并的比特门限。 具 体地：  The UE determines the bit threshold of the CSI information combining period according to the carrier corresponding to the CSI information. specifically:
UE判断冲突的 CSI信息中是否有主载波对应的周期 CSI信息；  The UE determines whether there is periodic CSI information corresponding to the primary carrier in the conflicting CSI information;
如果有， UE确定第七比特门限为周期 CSI信息合并的比特门限；  If yes, the UE determines that the seventh bit threshold is a bit threshold for combining the periodic CSI information;
如果没有， UE确定第八比特门限为周期 CSI信息合并的比特门限。  If not, the UE determines that the eighth bit threshold is a bit threshold for the periodic CSI information combining.
实际应用中， 才 居系统实际需求选择上述任一种方式确定周期 CSI信息合并的比特门 限。 应当指出的是， 也可以根据其他规则确定周期 CSI信息。 只要是根据冲突的周期 CSI 信息从多个预置的比特门限中选择一个作为本次周期 CSI信息合并所使用的比特门限， 均 落入本发明的保护范围。 如果釆用上述第一、或第二种方式确定周期 CSI信息合并的比特门限。那么，步骤 110 的具体实现方式可以是： UE按照预定的周期 CSI信息的 reporting type优先级规则， 对发 生冲突的周期 CSI信息排序。 In practical applications, the actual requirements of the system are selected to determine the bit threshold of the periodic CSI information combination. It should be noted that the periodic CSI information can also be determined according to other rules. It suffices to select one of a plurality of preset bit thresholds as the bit threshold used for the current period CSI information combining according to the periodic CSI information of the collision, and all fall within the protection scope of the present invention. If the first or second manner described above is used, the bit threshold of the periodic CSI information combination is determined. Then, the specific implementation manner of the step 110 may be: the UE sorts the conflicting periodic CSI information according to the reporting type priority rule of the predetermined periodic CSI information.
作为举例而非限定， 预定的周期 CSI信息的 reporting type优先级规则可以是： 对于相同传输点 （或千扰假设， 或载波）对应的周期 CSI信息， reporting type 3, 5, 6 的优先级高于 reporting type 1, la, 2, 2a, 2b, 2c, 4。  By way of example and not limitation, the reporting type priority rule of the predetermined periodic CSI information may be: for the periodic CSI information corresponding to the same transmission point (or interference assumption, or carrier), the reporting type 3, 5, 6 has a high priority. In reporting type 1, la, 2, 2a, 2b, 2c, 4.
对于不同传输点（或千扰假设，或载波）对应的周期 CSI信息， reporting types3, 5, 6, 2a 的优先级最高， reporting type 2, 2b, 2c, 4的优先级其次， reporting type 1 , la的优先级最低。  For the period CSI information corresponding to different transmission points (or interference assumptions, or carriers), reporting types3, 5, 6, 2a have the highest priority, reporting type 2, 2b, 2c, 4 has the highest priority, reporting type 1 La has the lowest priority.
对于发生冲突且 reporting type优先级相同的周期 CSI信息， UE按照预定的周期 CSI 信息的反馈类型优先级规则， 对发生冲突的周期 CSI信息排序， 进一步包括：  For the periodic CSI information of the conflicting and reporting type priority, the UE sorts the CSI information of the conflicting period according to the feedback type priority rule of the CSI information of the predetermined period, and further includes:

如果釆用上述第三种方式确定周期 CSI信息合并的比特门限， 上述步骤 110的具体实 现方式可以是： UE按照预定的周期 CSI信息对应的传输点优先级规则， 对发生冲突的周 期 CSI信息排序。  If the third embodiment of the foregoing method is used to determine the bit threshold of the periodic CSI information combination, the specific implementation of the foregoing step 110 may be: the UE sorts the conflicting CSI information according to the transmission point priority rule corresponding to the predetermined periodic CSI information. .
对于发生冲突且传输点优先级相同的周期 CSI信息， UE按照预定的周期 CSI信息对 应的传输点优先级规则， 对发生冲突的周期 CSI信息排序， 进一步包括：  For the periodic CSI information of the conflicting and the same priority of the transmission point, the UE sorts the CSI information of the conflicting period according to the transmission point priority rule corresponding to the predetermined periodic CSI information, and further includes:

如果釆用上述第四种方式确定周期 CSI信息合并的比特门限， 上述步骤 110的具体实 现方式可以是： UE按照预定的周期 CSI信息对应的千扰假设优先级规则， 对发生冲突的 周期 CSI信息排序。 If the fourth threshold is used to determine the bit threshold of the periodic CSI information combination, the specific implementation of the above step 110 The current mode may be: the UE sorts the conflicting periodic CSI information according to the interference assumption priority rule corresponding to the predetermined periodic CSI information.
对于发生冲突且千扰假设优先级相同的周期 CSI信息， UE按照预定的周期 CSI信息 对应的千扰假设优先级规则， 对发生冲突的周期 CSI信息排序， 进一步包括：  For the periodic CSI information with the conflicting and the same interference priority, the UE sorts the conflicting CSI information according to the interference criterion of the predetermined periodic CSI information, and further includes:

下面将结合具体的应用场景， 对本发明实施例提供的方法进行详细介绍。  The method provided by the embodiment of the present invention is described in detail below in conjunction with a specific application scenario.
在第一个应用场景中，假设 UE需要反馈 3个不同的千扰假设各自对应的 CSI (以 CSI report 1 , CSI report2, CSI report3表示）， 各个 CSI的上报周期由基站配置； UE根据配置 的上 4艮周期在 PUCCH中分别按照各自的 reporting type上 ·ί艮各个周期 CSI信息。  In the first application scenario, it is assumed that the UE needs to feed back the CSI corresponding to the three different interference assumptions (represented by CSI report 1, CSI report 2, and CSI report 3), and the reporting period of each CSI is configured by the base station; The upper 4 艮 period is in the PUCCH according to the respective reporting type.
UE和基站约定： reporting type相同时， CSI report索引值越低的， 周期 CSI信息的优 先级越高； reporting type不同时， 不同的 reporting type的优先级如下： 相同 CSI report中的 reporting types 3, 5, 6的优先级高于 reporting type 1, la, 2, 2a, 2b, 2c,The UE and the base station agree that when the reporting type is the same, the lower the CSI report index value, the higher the priority of the periodic CSI information; when the reporting type is different, the priority of the different reporting type is as follows: The reporting types 3, 5, 6 in the same CSI report have higher priority than reporting type 1, la, 2, 2a, 2b, 2c,
4。 4.
不同 CSI report的 reporting types优先级由高到低如下：  The reporting types of different CSI reports have priority from high to low as follows:
最高优先级： reporting type 3, 5, 6, 2a ；  Highest priority: reporting type 3, 5, 6, 2a;
次高优先级： reporting type 2, 2b, 2c, 4 ；  Second highest priority: reporting type 2, 2b, 2c, 4;
最低优先级： reporting type 1 , la。  Lowest priority: reporting type 1 , la.
同时， UE和基站约定： 如果周期 CSI信息中包含 RI, 则周期 CSI信息合并的比特门 限为 10比特； 否则该比特门限为 20比特。  At the same time, the UE and the base station agree that if the periodic CSI information includes the RI, the bit threshold of the periodic CSI information combination is 10 bits; otherwise, the bit threshold is 20 bits.
如果在某个上报时刻， UE需要同时上报 CSI report 1的 RI ( 2比特， reporting type 3 ), CSI report2的宽带 PMI/CQ 11比特， reporting type2 )和 CSI report3的 RI( 2比特， reporting type 3 )。 则周期 CSI上报实现方式如图 2所示， 具体包括如下操作：  If at a certain reporting time, the UE needs to simultaneously report the RI (2 bits, reporting type 3) of the CSI report 1, the wideband PMI/CQ 11 bits of the CSI report 2, the reporting type 2 ) and the RI of the CSI report 3 (2 bits, reporting type 3) ). The implementation manner of the periodic CSI reporting is as shown in Figure 2, which specifically includes the following operations:
步骤 200、 UE确定发生冲突的周期 CSI信息中包含 RI信息；  Step 200: The UE determines that the conflicting period CSI information includes RI information.
步骤 210、 UE确定在该上 ·ί艮时刻， 周期 CSI信息合并的比特门限为 10比特； 步骤 220、 UE按照与基站约定的优先级规则， 对发生冲突的周期 CSI信息排序。  Step 210: The UE determines that the bit threshold of the periodic CSI information combination is 10 bits at the time of the last time. Step 220: The UE sorts the conflicting CSI information according to the priority rule agreed with the base station.
具体的，按照上述约定，冲突的周期 CSI信息排序结果为 {CSI report 1的 RI, CSI report3 的 RI, CSI report2的宽带 PMI/CQI }。 其顺序为周期 CSI信息的优先级的降序。  Specifically, according to the above agreement, the conflicting CSI information ranking result is {RI of CSI report 1, RI of CSI report3, and broadband PMI/CQI of CSI report2. The order is the descending order of priority of the periodic CSI information.
步骤 230、在 10比特范围内，UE按照冲突的周期 CSI信息的优先级降序选择 CSI report 1 的 RI和 CSI report3的 RI。  Step 230: In the 10-bit range, the UE selects the RI of the CSI report 1 and the RI of the CSI report 3 in descending order of priority of the conflicting period CSI information.
步骤 240、 UE将 CSI report 1的 RI和 CSI report3的 RI合并后在该上 4艮时刻的 PUCCH 中上艮。  Step 240: The UE combines the RI of the CSI report 1 and the RI of the CSI report3, and then uploads it in the PUCCH of the last time.
根据 10比特的门限 , UE只能上报前两个 RI信息，不能上报 CSI report2的宽带 PMI/CQI 信息， 因此在该上报时刻的 PUCCH中实际上报的信息为 {CSI report 1的 RI, CSI report3 的 RI}。  According to the 10-bit threshold, the UE can only report the first two RI information, and cannot report the wideband PMI/CQI information of the CSI report2. Therefore, the information actually reported in the PUCCH at the reporting time is {CSI report 1 RI, CSI report3 RI}.
通过上述处理过程 , 当发生冲突的周期 CSI信息中包含 RI信息时，优先上报 RI信息， 并且通过选择 RI信息对应的比特门限， 保证了 RI信息的传输性能。  Through the above process, when the RI information is included in the CSI information of the conflicting period, the RI information is preferentially reported, and the transmission threshold performance of the RI information is ensured by selecting the bit threshold corresponding to the RI information.
在第二个应用场景中，假设 UE需要反馈 3个不同的千扰假设各自对应的 CSI (以 CSI report 1 , CSI report2, CSI report3表示）， 各个 CSI的上报周期由基站配置； UE根据配置 的上 4艮周期在 PUCCH中分别按照各自的 reporting type上 ·ί艮各个周期 CSI信息。  In the second application scenario, it is assumed that the UE needs to feed back the CSI corresponding to the three different interference assumptions (represented by CSI report 1, CSI report 2, and CSI report 3), and the reporting period of each CSI is configured by the base station; The upper 4 艮 period is in the PUCCH according to the respective reporting type.
UE和基站约定： reporting type相同时， CSI report索引值越低的， 周期 CSI信息的优 先级越高； reporting type不同时， 不同的 reporting type的优先级如下：  The UE and the base station agree that when the reporting type is the same, the lower the CSI report index value, the higher the priority of the periodic CSI information; when the reporting type is different, the priority of different reporting types is as follows:
相同 CSI report中的 reporting types 3, 5, 6的优先级高于 reporting type 1, la, 2, 2a, 2b, 2c, 4。 The reporting types 3, 5, 6 in the same CSI report have higher priority than reporting type 1, la, 2, 2a, 2b, 2c, 4.
不同 CSI report的 reporting types优先级由高到低如下：  The reporting types of different CSI reports have priority from high to low as follows:
最高优先级： reporting type 3, 5, 6, 2a;  Highest priority: reporting type 3, 5, 6, 2a;
次高优先级： reporting type 2, 2b, 2c, 4;  Second highest priority: reporting type 2, 2b, 2c, 4;
最低优先级： reporting type 1 , la。  Lowest priority: reporting type 1 , la.
同时， UE和基站约定： 如果冲突的周期 CSI信息中包含优先级最高的 reporting type 的 CSI信息， 则周期 CSI信息合并的比特门限为 10比特； 如果冲突的周期 CSI信息中不 包含优先级最高的 reporting type的周期 CSI信息，但包含优先级次高的 reporting type的周 期 CSI信息， 则周期 CSI信息合并的比特门限为 15比特； 如果冲突的周期 CSI信息中只 包含优先级最低的 reporting type的周期 CSI信息， 则周期 CSI信息合并的比特门限为 20 比特。  At the same time, the UE and the base station agree that: if the conflicting periodic CSI information includes the CSI information of the reporting type with the highest priority, the bit threshold of the periodic CSI information is 10 bits; if the conflicting periodic CSI information does not include the highest priority The periodic CSI information of the reporting type, but the periodic CSI information of the reporting type with the second highest priority, the bit threshold of the periodic CSI information combination is 15 bits; if the conflicting periodic CSI information only includes the period of the lowest priority reporting type For CSI information, the bit threshold for combining the periodic CSI information is 20 bits.
如果在某个上报时刻中， UE需要同时上报 CSI report 1的窄带 CQI ( 12比特， reporting typel ), CSI report2的宽带 PMI/CQ 8比特， reporting type2 )和 CSI report3的宽带 PMI/CQI ( 8比特， reporting type2 )。 则周期 CSI上 4艮实现方式如图 3所示， 具体包括如下操作： 步骤 300、 UE确定发生冲突的周期 CSI信息中不包含优先级最高的 reporting type的 周期 CSI信息， 但包含优先级次高的 reporting type的周期 CSI信息；  If at a certain reporting time, the UE needs to simultaneously report the narrowband CQI (12 bits, reporting typel) of CSI report 1, the wideband PMI/CQ 8 bits of CSI report2, the reporting type 2) and the wideband PMI/CQI of CSI report3 (8 bits). , reporting type2). As shown in FIG. 3, the implementation of the periodic CSI is as follows: Step 300: The UE determines that the periodic CSI information of the conflicting period does not include the periodic CSI information of the reporting type with the highest priority, but includes the second highest priority. Periodic CSI information of the reporting type;
步骤 310、 UE确定该上报时刻， 周期 CSI信息合并的比特门限为 15比特。  Step 310: The UE determines the reporting time, and the bit threshold of the combined CSI information is 15 bits.
步骤 320、 UE按照与基站约定的优先级规则， 对发生冲突的周期 CSI信息排序。 具体的， 按照上述约定， 冲突的周期 CSI 信息排序结果为 {CSI report2 的宽带 PMI/CQI , CSI report3的宽带 PMI/CQI, CSI reportl的窄带 CQI}。 其顺序为周期 CSI信 息的优先级的降序。  Step 320: The UE sorts the CSI information of the conflicting period according to the priority rule agreed with the base station. Specifically, according to the above agreement, the conflicting CSI information ranking result is {CSI report2 broadband PMI/CQI, CSI report3 broadband PMI/CQI, CSI reportl narrowband CQI}. The order is the descending order of priority of the periodic CSI information.
步骤 330、在 15比特范围内，UE按照冲突的周期 CSI信息的优先级降序选择 CSI report2 的宽带 PMI/CQI。  Step 330: In the 15-bit range, the UE selects the broadband PMI/CQI of the CSI report2 according to the priority descending order of the conflicting period CSI information.
步骤 340、 UE将 CSI report2的宽带 PMI/CQI在该上报时刻的 PUCCH中上报。  Step 340: The UE reports the broadband PMI/CQI of the CSI report2 in the PUCCH of the reporting time.
根据 15比特的门限， UE只能上报 CSI report2的宽带 PMI/CQI信息， 不能上报优先 级较低的两个信息， 因此在该上报时刻的 PUCCH中实际上报的信息为 {CSI report2的宽带 PMI/CQI }。  According to the 15-bit threshold, the UE can only report the broadband PMI/CQI information of the CSI report2, and cannot report two pieces of information with lower priority. Therefore, the information actually reported in the PUCCH at the reporting time is {the broadband PMI of the CSI report2/ CQI }.
通过上述处理过程， 可以确保 reporting type优先级较高的周期 CSI信息的上报， 并能 够满足上 ·ί艮的周期 CSI信息的传输性能需求。  Through the above process, the reporting of periodic CSI information with a higher priority of the reporting type can be ensured, and the transmission performance requirement of the CSI information of the periodic period can be satisfied.
在第三个应用场景中， 假设 UE 需要反馈 3 个不同传输点各自对应的 CSI (以 CSI reportl , CSI report2, CSI report3表示）， 各个 CSI的上报周期由基站配置； UE根据配置 的上 ·ί艮周期在 PUCCH中分别按照各自的 reporting type上 ·ί艮各个周期 CSI信息。 In the third application scenario, it is assumed that the UE needs to feed back the CSI corresponding to each of the three different transmission points (represented by CSI report1, CSI report2, CSI report3), and the reporting period of each CSI is configured by the base station; The upper 艮 cycle is in the PUCCH according to the respective reporting type.
UE和基站约定了不同传输点的优先级，并约定优先级越高的传输点其对应的周期 CSI 信息的优先级越高。 假设优先级为 CSI reportl> CSI report2> CSI report3 , 其中 CSI report 1 对应的传输点为主传输点。  The UE and the base station agree on the priorities of different transmission points, and the higher the priority of the transmission point, the higher the priority of the corresponding period CSI information. Assume that the priority is CSI report1> CSI report2> CSI report3, where the transmission point corresponding to CSI report 1 is the primary transmission point.
同时， UE和基站约定： 如果冲突的周期 CSI信息中包含主传输点的反馈信息， 则周 期 CSI信息合并的比特门限为 15比特； 否则该比特门限为 20比特。  At the same time, the UE and the base station agree that if the conflicting periodic CSI information includes the feedback information of the primary transmission point, the phase threshold of the combined CSI information is 15 bits; otherwise, the bit threshold is 20 bits.
如果在某个上报时刻中， UE需要同时上报 CSI report 1的 RI( 2比特， reporting type 3 ), If the UE needs to report the RI (2 bits, reporting type 3) of CSI report 1 at the same time,
CSI report2的宽带 PMI/CQ 11比特， reporting type2 )和 CSI report3的 RI( 2比特， reporting type 3 ), 则周期 CSI上报实现方式如图 4所示， 具体包括如下操作： The CSI report2 broadband PMI/CQ 11 bits, reporting type2) and CSI report3 RI (2 bits, reporting type 3), the periodic CSI reporting implementation is shown in Figure 4, which includes the following operations:
步骤 400、 UE确定发生冲突的周期 CSI信息中包含主传输点对应的周期 CSI信息； 步骤 410、 UE确定在上 ·ί艮时刻， 周期 CSI信息合并的比特门限为 15比特。  Step 400: The UE determines the period in which the collision occurs. The CSI information includes the periodic CSI information corresponding to the primary transmission point. Step 410: The UE determines that the bit threshold of the periodic CSI information combination is 15 bits at the time of the last.
步骤 420、 UE按照与基站约定的优先级规则， 对发生冲突的周期 CSI信息排序。 具体的，按照上述约定，冲突的周期 CSI信息排序结果为 {CSI report 1的 RI, CSI report2 的 PMI/CQI, CSI report3的宽带 RI }。 其顺序为周期 CSI信息的优先级的降序。  Step 420: The UE sorts the CSI information of the conflicting period according to the priority rule agreed with the base station. Specifically, according to the above agreement, the conflicting CSI information ranking result is {RI of CSI report 1, PMI/CQI of CSI report2, and broadband RI of CSI report3. The order is the descending order of priority of the periodic CSI information.
步骤 430、在 15比特范围内，UE按照冲突的周期 CSI信息的优先级降序选择 CSI report 1 的 RI和 CSI report2的 PMI/CQL  Step 430: In the 15-bit range, the UE selects the RI of the CSI report 1 and the PMI/CQL of the CSI report 2 in descending order of priority of the conflicting CSI information.
步骤 440、 UE将 CSI report 1的 RI和 CSI report2的 PMI/CQI合并后在该上 4艮时刻的 Step 440: The UE combines the RI of the CSI report 1 and the PMI/CQI of the CSI report 2 at the time of the last 4
PUCCH中上艮。 In the PUCCH.
根据 15比特的门限， UE只能上报优先级最高的前两个 CSI信息， 不能上报最后一个 信息， 因此在该上报时刻的 PUCCH中实际上报的信息为 {CSI report 1的 RI, CSI report2 的 PMI/CQI}。  According to the 15-bit threshold, the UE can only report the first two CSI information with the highest priority, and cannot report the last information. Therefore, the information actually reported in the PUCCH at the reporting time is {CSI report 1 RI, CSI report 2 PMI. /CQI}.
通过上述处理过程， UE 与基站约定主传输点具有最高优先级， 从而确保主传输点对 应的周期 CSI信息的上报， 并能够满足主传输点对应的 CSI信息的传输性能需求。  Through the foregoing process, the UE and the base station agree that the primary transmission point has the highest priority, thereby ensuring the reporting of the periodic CSI information corresponding to the primary transmission point, and meeting the transmission performance requirement of the CSI information corresponding to the primary transmission point.
在第四个应用场景中，假设 UE需要反馈 3个不同载波各自对应的 CSK以 CSI report 1 , CSI report2, CSI report3表示）， 各个 CSI的上报周期由基站配置； UE根据配置的上报周 期在 PUCCH中分别按照各自的 reporting type上 ·ί艮各个周期 CSI信息。  In the fourth application scenario, it is assumed that the UE needs to feed back the corresponding CSKs of the three different carriers to be represented by CSI report 1, CSI report2, and CSI report3, and the reporting period of each CSI is configured by the base station; the UE reports the periodicity according to the configured period in the PUCCH. Each of the CSI information is updated according to the respective reporting type.
UE和基站约定了不同载波的优先级， 并约定优先级越高的载波其对应的周期 CSI信 息的优先级越高。 假设优先级为 CSI report 1> CSI report2> CSI report3 , 其中 CSI report 1对 应的载波为主载波。  The UE and the base station agree on the priorities of different carriers, and the higher the priority of the carrier, the higher the priority of the corresponding period CSI information. Assume that the priority is CSI report 1> CSI report2> CSI report3, where the carrier corresponding to CSI report 1 is the primary carrier.
同时， UE和基站约定： 如果冲突的周期 CSI信息中包含主载波的反馈信息， 则周期 At the same time, the UE and the base station agree: if the conflicting period CSI information includes feedback information of the primary carrier, the period
CSI信息合并的比特门限为 15比特； 否则该比特门限为 20比特。 如果在某个上报时刻中， UE需要同时上报 CSI report 1的 RI( 2比特， reporting type 3 ),The bit threshold for CSI information combining is 15 bits; otherwise the bit threshold is 20 bits. If the UE needs to report the RI (2 bits, reporting type 3) of CSI report 1 at the same time,
CSI report2的宽带 PMI/CQ 11比特， reporting type2 )和 CSI report3的 RI( 2比特， reporting type 3 ), 则周期 CSI上报实现方式如图 5所示， 具体包括如下操作： The CSI report2 broadband PMI/CQ 11 bits, reporting type2) and CSI report3 RI (2 bits, reporting type 3), the periodic CSI reporting implementation is as shown in Figure 5, including the following operations:
步骤 500、 UE确定发生冲突的周期 CSI信息中包含主载波对应的周期 CSI信息； 步骤 510、 UE确定在上 ·ί艮时刻， 周期 CSI信息合并的比特门限为 15比特。  Step 500: The UE determines the period in which the collision occurs. The CSI information includes the periodic CSI information corresponding to the primary carrier. Step 510: The UE determines that the time threshold of the combined CSI information is 15 bits at the time of the last.
步骤 520、 UE按照与基站约定的优先级规则， 对发生冲突的周期 CSI信息排序。 具体的，按照上述约定，冲突的周期 CSI信息排序结果为 {CSI report 1的 RI, CSI report2 的 PMI/CQI, CSI report3的宽带 RI }。  Step 520: The UE sorts the CSI information of the conflicting period according to the priority rule agreed with the base station. Specifically, according to the above agreement, the conflicting CSI information ranking result is {RI of CSI report 1, PMI/CQI of CSI report2, and broadband RI of CSI report3.
步骤 530、在 15比特范围内，UE按照冲突的周期 CSI信息的优先级降序选择 CSI report 1 的 RI。  Step 530: In the 15-bit range, the UE selects the RI of the CSI report 1 in descending order of priority of the conflicting period CSI information.
步骤 540、 UE将 CSI report 1的 RI在该上 4艮时刻的 PUCCH中上艮。  Step 540: The UE uploads the RI of the CSI report 1 to the PUCCH at the last time.
根据 15比特的门限， UE只能上报优先级最高的第一个 CSI信息， 不能上报后面两个 CSI信息， 因此在该上报时刻的 PUCCH中实际上报的信息为 {CSI report 1的 RI }。  According to the 15-bit threshold, the UE can only report the first CSI information with the highest priority, and cannot report the latter two CSI information. Therefore, the information actually reported in the PUCCH at the reporting time is RI } of the CSI report 1.
通过上述处理过程， UE 与基站约定主载波具有最高优先级， 从而确保主载波对应的 周期 CSI信息的上报， 并能够满足主载波对应的 CSI信息的传输性能需求。  Through the foregoing process, the UE and the base station agree that the primary carrier has the highest priority, so as to ensure the reporting of the periodic CSI information corresponding to the primary carrier, and can meet the transmission performance requirement of the CSI information corresponding to the primary carrier.
