Abstract

本发明实施例提供了一种资源调度方法，涉及领域无线通信技术领域，所述方法包括：被调度设备接收调度设备发送的预调度信息和动态调度信息，当该预调度信息指示该调度设备在预调度资源区间内为该被调度设备分配无线资源时，在该预调度信息所指示的无线资源上进行数据发送或数据接收或控制信令检测；当该动态调度信息指示该调度设备在动态调度资源区间内为被调度设备分配无线资源时，在该动态调度资源区间内的资源上进行控制信令检测。被调度设备不需要在所有的资源上进行控制信令检测，从而降低了被调度设备的功耗，提高被调度设备的续航能力。

Description

调度设备、被调度设备、资源调度方法及装置 技术领域
本发明涉及无线通信技术领域，特别涉及一种调度设备、被调度设备、资源调度方法及装置。
背景技术
在无线蜂窝网络中，调度设备通过调度机制来决定一个被调度设备使用哪些资源进行数据通信。
在传统的资源调度机制中，调度设备(例如基站、无线接入点、中继站等，以下统称调度设备)在每个调度周期更新一次资源调度的结果，并将调度结果通知给被调度设备，例如用户被调度设备UE、移动台MS等。例如，在长期演进(英文：Long Term Evolution，缩写：LTE)系统中，以调度设备为基站，被调度设备为用户设备UE为例，基站每1ms更新一次调度结果，基站通过物理下行控制信道(英文：Physical Downlink Control Channel，缩写：PDCCH)向UE发送用于指示承载被UE收发无线资源的调度信息。在每个动态调度周期(一般为一个子帧，1ms)内，处于链接状态的UE会持续对基站下发的PDCCH进行盲检测，以获得无线资源调度信息。典型的，在一个动态调度周期(1个子帧，即1ms)内，UE会在一个载波上进行32次盲检测。
在实现本发明的过程中，发明人发现相关技术至少存在以下问题：
在传统的资源调度机制中，UE需要在每个子帧进行PDCCH盲检测，功耗较大，影响被调度设备的续航能力。
发明内容
为了解决现有技术中被调度设备在每个子帧进行PDCCH盲检测，功耗较大，影响被调度设备的续航能力的问题，本申请提供了一种调度设备、被调度设备、资源调度方法及装置。
第一方面，本发明提供了一种资源调度方法，该方法包括：被调度设备接收调度设备发送的调度指示信息，该调度指示信息中包含预调度信息和动态调

Claims (1)

  1. 度信息；当该预调度信息指示该调度设备在预调度资源区间内为该被调度设备分配无线资源时，该被调度设备在该预调度信息所指示的无线资源上进行数据接收或发送或进行控制信令的检测；当该动态调度信息指示该调度设备在动态调度资源区间内为被调度设备分配无线资源时，该被调度设备在该动态调度资源区间内的资源上进行数据接收或发送或进行控制信令检测；其中，该预调度信息所指示的无线资源为该预调度资源区间内的时频资源，该预调度资源区间是至少一个调度期内可用的时频资源区间中包含的全部或者部分资源区间；该动态调度资源区间是该至少一个调度期内可用的时频资源区间中包含的、处于该预调度资源区间之外的部分资源区间或全部资源区间。即被调度设备不需要在所有资源上都进行控制信令的检测，从而降低了被调度设备的功耗，提高被调度设备的续航能力。
    在第一方面的第一种可能实现方式中，该方法还包括：当该预调度信息指示该调度设备不在该预调度资源区间内为该被调度设备分配无线资源时，被调度设备在预调度资源期间不进行数据接收或发送或进行控制信令检测；当该动态调度信息指示该调度设备不在该动态调度资源区间内为该被调度设备分配无线资源时，被调度设备在动态调度资源区间不进行数据接收或发送或进行控制信令检测。其中，该预调度信息所指示的无线资源为该预调度资源区间内的时频资源，该预调度资源区间是至少一个调度期内可用的时频资源区间中包含的全部或者部分资源区间；该动态调度资源区间是该至少一个调度期内可用的时频资源区间中包含的、处于该预调度资源区间之外的部分资源区间或全部资源区间。即预调度信息或者动态调度信息指示调度设备不在预调度资源区间或者动态调度资源区间内为被调度设备分配无线资源时，被调度设备在相应的资源区间内的所有资源上都不进行控制信令的检测，从而进一步降低了被调度设备的功耗，提高被调度设备的续航能力。
    在第一方面的第二种可能实现方式中，该方法还包括：当该预调度信息指示该调度设备不在该预调度资源区间内为该被调度设备分配无线资源，且该动态调度信息指示该调度设备不在该动态调度资源区间内为该被调度设备分配无线资源时，该被调度设备进入休眠模式，即当被调度设备在预调度资源区间和动态调度资源区间都不需要进行数据传输时，可以直接进入休眠模式，进一步降低被调度设备功耗的效果。
