- PDCCH Physical Downlink Control Channel
- DCI Downlink Control Information
- PDSCH Physical Downlink Shared Channel
- PUSCH Physical Uplink Shared Channel
- DCI can be used to transmit common control information, carried via PDCCH.
- Network devices configure a search space for terminal devices. Different aggregation levels (ALs) can be configured, specifying the number of candidate PDCCHs the terminal device needs to monitor at each aggregation level. Terminal devices perform PDCCH detection within the search space. The maximum number of PDCCHs a terminal device can monitor in a single time slot is related to the subcarrier spacing.
- As aggregation levels
- the maximum number of PDCCHs a terminal device can monitor in a single time slot is 44.
- the subcarrier spacing parameter ⁇ takes values of 0, 1, 2, and 3, it corresponds to subcarrier spacings of 15kHz, 30kHz, 60kHz, and 120kHz, respectively.
- Terminal devices are designed to support extremely high peak data rates in NR Release 15 or 16 (R15/R16). Therefore, the requirements for terminal capabilities are high.
- the LTE standard defines a maximum single-carrier bandwidth of 20MHz, with larger bandwidths achieved through multi-carrier aggregation.
- 5G NR ultimately defines a maximum carrier bandwidth of 100MHz for frequencies below 6GHz, five times that of LTE, and a maximum carrier bandwidth of 400MHz for millimeter-wave frequencies.
- the required multiple-input multiple-output (MIMO) antenna configuration for NR has also been further increased.

- NR applications do not require such high processing power in terms of capacity and speed. These applications include the Internet of Things (IoT), industrial automation, and wearable devices. These scenarios demand communication hardware with low size and power consumption; lightweight capability is a characteristic of these terminals. Based on this consideration, NR R17 research introduced a compact terminal standard with reduced capabilities.

This compact terminal design significantly reduces the complexity of terminal hardware and correspondingly reduces power consumption, thus achieving energy savings.
- terminal devices can only detect PDCCH within the search space configured by network devices.
- the terminal device determines whether it needs to receive downlink data or send uplink data by detecting whether the network device has sent a PDCCH.
- detecting PDCCH consumes energy, and continuous PDCCH detection is detrimental to energy conservation and power saving.

接下来,对本申请实施例涉及的相关技术进行介绍:
·物理下行控制信道(Physical Downlink Control CHannel,PDCCH)检测:
网络设备向终端设备发送下行控制信息(Downlink Control Information,DCI),DCI用于下行调度例如调度物理下行共享信道(Physical Downlink Shared CHannel,PDSCH),或上行授权例如调度物理上行共享信道(Physical Uplink Shared CHannel,PUSCH),或者DCI用于传输公共控制信息,DCI通过PDCCH承载。网络设备为终端设备配置搜索空间(search space),网络设备可以配置不同的聚合等级(Aggregation Level,AL),在每种聚合等级下,配置终端设备需要监测的候选PDCCH数量。终端设备需要在搜索空间中执行PDCCH检测,终端设备在一个时隙内能够监测的PDCCH的最大数量与子载波间隔相关,例如,在15kHz子载波间隔时,终端设备在一个时隙内能够监测的PDCCH最大数量是44。参见表1,子载波间隔参数μ取值为0,1,2,3时,分别对应子载波间隔15kHz,30kHz,60kHz和120kHz;
表1
·终端设备复杂度优化:
终端设备可以简称为终端,NR第15版本或第16版本(Release 15/Release 16,R15/R16)中的终端设计支持极高的峰值速率。因此,对终端的能力要求较高。LTE标准定义单载波带宽最大为20MHz,更大的带宽通过多载波聚合实现。5G NR最终定义低于6GHz频段的最大载波带宽为100MHz,是LTE的5倍,而毫米波频段的最大载波带宽为400MHz。NR所要求的多输入多输出(Multiple-Input Multiple-Output,MIMO)天线规模也进一步提高。LTE的终端天线参考配置是一发双收,而NR R15在2500MHz以上的频点要求双发四收天线。NR的R15/R16也没有支持半双工,要求对上下行所有的时隙都能够做数据处理。
然而,在处理容量和速度上,NR的一些应用场景并不需要这么高的处理能力,这些场景包括物联网、工业自动化和可穿戴设备的应用。而这些场景下,都要求通信硬件有较低的体积和功耗,轻量化的能力要求是这类终端的特征。基于这样的考虑,NR R17研究引入缩减能力的紧凑型终端标准。
紧凑型终端标准对一些NR R15/R16的必选的能力进行了缩减。针对这类能力定义了相应的终端功能组。紧凑型终端标准还进一步优化终端识别,接入过程和优化测量上的功耗以适应相关的应用场景。这样的紧凑型终端的设计可以明显降低终端硬件的复杂度。同时还能够相应地降低终端的能耗,也能达到节能的作用。
相关技术中,终端设备只能在网络设备配置的搜索空间中检测PDCCH,终端设备通过检测网络设备是否发送了PDCCH进而判断是否需要接收下行数据或者发送上行数据。但是终端设备检测PDCCH会消耗能量,一直检测PDCCH不利于终端设备的节能降耗。为了解决上述问题,本申请实施例提供了一种配置方法,图2示出了本申请一个示例性实施例提供的配置方法的流程图,该方法由终端设备执行,该方法包括:
步骤210:获取第一配置信息。

在一些实施例中,获取第一配置信息,包括:基于系统信息块(System Information Block,SIB)或无线资源控制(Radio Resource Control,RRC)信令获取第一配置信息。可选地,该第一配置信息采用半静态配置的方式配置至少一组传输资源。
通过将第一配置信息携带在SIB或RRC信令中不需要额外的信令,减少信令传输开销,并且能够在终端设备连接网络设备后进行快速配置,加快接入网络的过程,此外能够在系统信息更新过程中对终端设备进行配置,更加灵活地管理和调整终端设备。

在一些实施例中,其它传输资源包括:至少一个第二传输资源;和/或,至少一个第三传输资源;其中,第二传输资源用于传输DCI和/或下行数据,第三传输资源用于传输反馈信息和/或上行数据。

在传输资源之间的对应关系是一对一的情况下,终端设备可以对每个接收到的下行数据继续进行即时反馈,反馈时延低;在传输资源之间的对应关系是多对一的情况下,针对接收到的多个下行数据,终端设备反馈一个上行数据,降低上行传输的系统开销。
