技术领域Technical field
本公开涉及通信技术领域，尤其涉及一种物理下行控制信道PDCCH的检测方法及终端。The present disclosure relates to the field of communication technologies, and in particular, to a method and a terminal for detecting a physical downlink control channel (PDCCH).
背景技术Background technique
在NR(New Radio，新无线)***中，PDCCH(Physical Downlink Control Channel，物理下行控制信道)用于承载下行控制信息，使用CCE(Control Channel Element，控制信道单元)作为基本逻辑单元，每个CCE对应确定的比特数。基站发给终端的数据使用不同的AL(Aggregation Level，聚合等级)，可能的取值是1、2、4、8、16等。基站根据UE(终端)的负载和信道状态等因素确定AL，负载量大或信道条件恶劣时，为保证传输质量，通常会采用较高的AL。In the NR (New Radio) system, the PDCCH (Physical Downlink Control Channel) is used to carry downlink control information, and the CCE (Control Channel Element) is used as the basic logical unit. Each CCE Corresponds to the determined number of bits. The data sent by the base station to the terminal uses different AL (Aggregation Level, aggregation level), the possible values are 1, 2, 4, 8, 16 and so on. The base station determines the AL based on factors such as the load of the UE (terminal) and the channel state. When the load is large or the channel conditions are bad, in order to ensure the transmission quality, a higher AL is usually used.
基站发给不同UE的信息在PDCCH中复用，特定AL的数据映射到PDCCH中一些特定的位置上。The information sent by the base station to different UEs is multiplexed in the PDCCH, and data of a specific AL is mapped to some specific positions in the PDCCH.
为了区分不同的UE，发送的信息的CRC(循环校验码)比特使用RNTI(Radio Network Temporary Identifier，无线网络临时标识)进行加扰，RNTI与发送信息的功能和UE ID有关。In order to distinguish different UEs, CRC (cyclic check code) bits of transmitted information are scrambled using RNTI (Radio Network Temporary Identifier, wireless network temporary identifier). RNTI is related to the function of sending information and UE ID.
UE收到寻呼信号后，进入Connected(连接)态并监测PDCCH，但并不知道要接收信息的明确的聚合等级和在PDCCH中所处的位置，只能从高层得到AL的可选范围，每个AL对应多个可能的位置；After receiving the paging signal, the UE enters the Connected state and monitors the PDCCH, but does not know the clear aggregation level of the information to be received and its position in the PDCCH. It can only obtain the optional range of AL from the upper layer. Each AL corresponds to multiple possible positions;
因此需要对这些位置进行多次盲检，即对每个可能的位置和长度进行译码、解扰和CRC校验，校验通过，则结束盲检并获得所需的PDCCH信息，校验不通过则对下一个可能的位置进行同样的操作直到遍历所有位置。最终 才能接收到自己的信息，这一过程消耗较多电量。Therefore, it is necessary to perform multiple blind checks on these positions, that is, to decode, descramble and CRC check every possible position and length. If the check passes, the blind check ends and the required PDCCH information is obtained. Pass and do the same for the next possible position until all positions are traversed. Eventually, you can receive your own information, and this process consumes more power.

具体实施方式Detailed ways
下面将参照附图更详细地描述本公开的示例性实施例。虽然附图中显示了本公开的示例性实施例，然而应当理解，可以以各种形式实现本公开而不应被这里阐述的实施例所限制。相反，提供这些实施例是为了能够更透彻地理解本公开，并且能够将本公开的范围完整的传达给本领域的技术人员。Hereinafter, exemplary embodiments of the present disclosure will be described in more detail with reference to the accompanying drawings. Although exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure can be implemented in various forms and should not be limited by the embodiments set forth herein. On the contrary, these embodiments are provided to enable a thorough understanding of the present disclosure, and to fully convey the scope of the present disclosure to those skilled in the art.
如图1所示，本公开的实施例提供一种物理下行控制信道PDCCH的检测方法，包括：As shown in FIG. 1, an embodiment of the present disclosure provides a method for detecting a physical downlink control channel PDCCH, including:
步骤11，获取聚合等级与信道状态的对应关系。终端在获取聚合等级(AL)与信道状态的对应关系时，可以通过***消息获取，如接收基站发送的***消息，该***消息中携带有聚合等级(AL)与信道状态的对应关系；这里的信道状态可以是由SINR(Signal to Interference plus Noise Ratio，信号与干扰加噪声比)作为指标来表示，当然，也可以由其它信道状态信息来表示。Step 11: Obtain the correspondence between the aggregation level and the channel state. When the terminal obtains the correspondence between the aggregation level (AL) and the channel state, it can obtain it through a system message, such as receiving a system message sent by the base station. The system message carries the correspondence between the aggregation level (AL) and the channel state. The channel state can be represented by SINR (Signal, Interference, and Noise Ratio) as an indicator, and of course, it can also be represented by other channel state information.
步骤12，根据所述对应关系，进行物理下行控制信道PDCCH的盲检。这样终端就不需要针对每个AL对应多个可能的位置都进行盲检，从而减少PDCCH盲检的次数，降低终端的功耗。Step 12: Perform a blind detection of the physical downlink control channel PDCCH according to the corresponding relationship. In this way, the terminal does not need to perform blind detection for multiple possible positions corresponding to each AL, thereby reducing the number of PDCCH blind detections and reducing the power consumption of the terminal.
本公开的一具体实施例中，上述步骤12具体可以包括：In a specific embodiment of the present disclosure, the above step 12 may specifically include:
步骤121，根据聚合等级与信道状态信息的对应关系，确定盲检的聚合等级的顺序。确定盲检的聚合等级的顺序时，可以通过以下方式实现：Step 121: Determine the order of the blindly detected aggregation levels according to the correspondence between the aggregation levels and the channel state information. When determining the order of the aggregation levels for blind inspection, this can be achieved in the following ways:
获取需要进行盲检的聚合等级的候选值以及当前的信道状态；具体来说， 终端可以通过对参考信号进行测量获得当前的信道状态；终端进入连接态后，接收高层通过信令发送的搜索空间配置，从而获取需要进行盲检的聚合等级的候选值。Obtain the candidate of the aggregation level that needs to be blindly checked and the current channel state; specifically, the terminal can obtain the current channel state by measuring the reference signal; after the terminal enters the connected state, it receives the search space sent by the upper layer through signaling Configuration to obtain candidate values for the aggregation levels that need to be blindly checked.
在所述对应关系中，若查找到当前的信道状态对应的聚合等级，将查找到的所述聚合等级作为盲检的起始聚合等级，并按预设顺序确定所述聚合等级的候选值中的其它聚合等级的盲检顺序；In the correspondence relationship, if an aggregation level corresponding to the current channel state is found, the found aggregation level is used as a starting aggregation level for blind detection, and a candidate value of the aggregation level is determined in a preset order. Sequence of blind inspection of other aggregation levels;
在所述对应关系中，若没有查找到当前的信道状态对应的聚合等级，在所述聚合等级的候选值中，将与所述当前的信道状态对应的聚合等级最接近的聚合等级作为盲检的起始聚合等级，并按预设顺序确定所述聚合等级的候选值中的其它聚合等级的盲检顺序。In the correspondence relationship, if the aggregation level corresponding to the current channel state is not found, among the candidate values of the aggregation level, the aggregation level closest to the aggregation level corresponding to the current channel state is used as a blind detection. And a blind detection order of other aggregation levels among the candidate values of the aggregation level in a preset order.
步骤122，根据所述聚合等级的顺序，进行PDCCH的盲检。Step 122: Perform a blind detection of the PDCCH according to the order of the aggregation levels.
例如：使用SINR作为信道状态指标，基站通过***信息发送AL和SINR的对应关系如下：For example: using SINR as the channel state indicator, the correspondence between the base station sending AL and SINR through system information is as follows:
ii 00 11 22 33 44
SINR范围SINR range (0,1](0,1) (1,2](1,2) (2,3](2,3) (3,4](3,4) (4,+∞)(4, + ∞)
ALAL 11 22 44 88 1616
假设UE在通过测量参考信号，得到SINR estimate＝2.8，终端接收到的高层信令指示的AL候选值为1、2、4、8、16，根据接收到的上述AL和SINR的对应关系表1和SINR estimate，可以确定对应的起始盲检AL＝4，其余的AL，可以按照预设顺序进行其它AL的盲检。这样，盲检时，以AL＝4作为起始盲检，并进一步的按预设顺序进行盲检，可以较大概率检测到正确的AL，不需要对各个AL都进行盲检，从而减少盲检的次数，降低终端的功耗。 Assume that the UE obtains SINR estimate = 2.8 by measuring the reference signal, and the candidate AL value indicated by the high-level signaling received by the terminal is 1, 2, 4, 8, and 16. According to the above-mentioned correspondence relationship between the AL and SINR, Table 1 And SINR estimate , it can be determined that the corresponding initial blind test AL = 4, and the remaining ALs can be blindly checked for other ALs in a preset order. In this way, when blind inspection is performed, AL = 4 is used as the initial blind inspection, and the blind inspection is further performed in a preset order. The correct AL can be detected with a higher probability, and no blind inspection is required for each AL, thereby reducing blind The number of inspections reduces the power consumption of the terminal.
本公开的上述实施例中，按预设顺序确定所述聚合等级的候选值中的其它聚合等级的盲检顺序具体可以包括以下三种方式中的至少一种：In the above embodiments of the present disclosure, the blind detection order for determining other aggregation levels among the candidate values of the aggregation level according to a preset order may specifically include at least one of the following three methods:
1)在所述聚合等级的候选值中，按照当前的信道状态与所述对应关系中的信道状态的接近程度的顺序，依次确定用于盲检的其它聚合等级；具体来说，1) among the candidate values of the aggregation level, in order of the closeness of the current channel state and the channel state in the corresponding relationship, other aggregation levels used for blind detection are determined in order; specifically,
根据公式：
Figure PCTCN2019089796-appb-000003
获得当前的信道状 态与所述对应关系中的信道状态的接近程度； According to the formula:
Figure PCTCN2019089796-appb-000003
Obtaining the closeness between the current channel state and the channel state in the corresponding relationship;
在所述聚合等级的候选值中，按照ΔSINR从小到大的顺序，依次确定用于盲检的聚合等级；Among the candidate values of the aggregation level, the aggregation level used for the blind detection is determined in order from ΔSINR in ascending order;
其中，ΔSINR表示当前的信道状态与所述对应关系中的信道状态的接近程度，SINR estimate为当前的信道状态，SINR i为所述对应关系中第i个信道状态，SINR i-1为所述对应关系中第i-1个信道状态。 Wherein, ΔSINR represents the closeness of the current channel state to the channel state in the corresponding relationship, SINR estimate is the current channel state, SINR i is the i-th channel state in the corresponding relationship, and SINR i-1 is the The i-1th channel state in the correspondence.
例如，按照ΔSINR从小到大的顺序，依次确定用于盲检的聚合等级时，对应的AL依次为8、2、16、1，即盲检的AL顺序为4、8、2、16、1。For example, when the aggregation level used for blind detection is determined in order from ΔSINR from small to large, the corresponding AL is 8, 2, 16, 1, and 1, in other words, the order of blind AL is 4, 8, 2, 16, 1, .
2)在所述聚合等级的候选值中，按照聚合等级从小到大顺序，依次确定用于盲检的其它聚合等级；2) Among the candidate values of the aggregation level, other aggregation levels for blind detection are determined in order from the descending order of the aggregation level;
例如，以SINR作为信道状态指标，基站发送的AL和SINR对应关系如下：For example, using SINR as the channel state indicator, the correspondence between AL and SINR sent by the base station is as follows:
ii 00 11 22 33 44
SINR范围SINR range (0,1](0,1) (1,2](1,2) (2,3](2,3) (3,4](3,4) (4,+∞)(4, + ∞)
ALAL 11 22 44 88 1616
假设UE在通过测量参考信号得到的SINR estimate＝0.5，从高层信令接收到的AL候选值为2、4、8、16；此时从对应关系表中，可以得到SINR estimate对应表中参考值AL＝1，AL候选值里不包括1，因此选择SINR最相近的AL＝2作为起始盲检的AL，后续顺序可以按聚合等级的候选值的从小到大的顺序，最终确定盲检的AL顺序为2、4、8、16。 Assume that the SINR estimate = 0.5 obtained by the UE by measuring the reference signal, and the AL candidate values received from high-level signaling are 2, 4, 8, 16; at this time, the reference value in the SINR estimate correspondence table can be obtained from the correspondence table. AL = 1, AL candidate value does not include 1. Therefore, AL = 2 with the closest SINR is selected as the AL for the initial blind detection. The subsequent order can be in the order of the candidate value of the aggregation level from small to large, and the blind detection is finally determined. The AL order is 2, 4, 8, 16.
3)在所述聚合等级的候选值中，按照聚合等级从大到小顺序，依次确定用于盲检的其它聚合等级；3) Among the candidate values of the aggregation level, other aggregation levels used for blind detection are determined in order from the aggregation level in descending order;
例如，以SINR作为信道状态指标，基站发送的AL和SINR对应关系如下：For example, using SINR as the channel state indicator, the correspondence between AL and SINR sent by the base station is as follows:
ii 00 11 22 33 44
SINR范围SINR range (0,1](0,1) (1,2](1,2) (2,3](2,3) (3,4](3,4) (4,+∞)(4, + ∞)
ALAL 11 22 44 88 1616
假设UE在通过测量参考信号得到的SINR estimate＝5，从高层信令接收到的AL候选值为1、2、4、8，此时从对应关系表中，可以得到SINR estimate对应表 中参考值AL＝16，AL候选值里不包括16，因此选择SINR最相近的AL＝8作为起始盲检的AL，后续顺序可以按聚合等级的候选值的从大到小的顺序，最终确定盲检的AL顺序为8、4、2、1。 Assuming that the SINR estimate = 5 obtained by the UE by measuring the reference signal, and the AL candidate values received from high-level signaling are 1, 2, 4, and 8, at this time, the reference value in the SINR estimate correspondence table can be obtained from the correspondence table. AL = 16, AL candidate value does not include 16. Therefore, AL with the closest SINR = 8 is selected as the AL for the initial blind detection. The subsequent order can be determined in the order of the candidate value of the aggregation level from large to small. The AL sequence is 8, 4, 2, 1.
本公开的上述实施例，通过根据AL与信道状态的对应关系，进行物理下行控制信道PDCCH的盲检；这样终端可以较早的检测到正确的AL，检测到正确的AL时，可以停止其余候选AL的检测，这样终端就不需要针对每个AL对应多个可能的位置都进行盲检，从而减少PDCCH盲检的次数，降低终端的功耗。The above embodiments of the present disclosure perform blind detection of the physical downlink control channel PDCCH according to the correspondence between the AL and the channel state; in this way, the terminal can detect the correct AL earlier, and can stop the remaining candidates when the correct AL is detected AL detection, so that the terminal does not need to perform blind detection for multiple possible positions corresponding to each AL, thereby reducing the number of blind PDCCH detections and reducing power consumption of the terminal.
