本申请基于申请号为201810031344.7、申请日为2018年01月12日的中国专利申请提出,并要求该中国专利申请的优先权,该中国专利申请的全部内容在此引入本申请作为参考。
技术领域
本申请涉及通信领域但不限于通信领域,尤其涉及一种调度处理方法及装置、存储介质、电子设备。
背景技术
随着无线通信技术的发展和用户对通信需求的日益增加,为了满足更高、更快和更新的通信需要,第五代移动通信(5th Generation,简称为5G)技术已成为未来网络发展的趋势。5G通信***被认为是在更高更宽的频带(例如3GHz以上)中实施,以便完成更高的数据速率。
在第三代合作伙伴计划(3rd Generation Partnership Project,3GPP)的新空口(New Radio,NR)需求报告中,明确了NR网络需要支持低时延高可靠业务(URLLC,Ultra-Reliable and Low Latency Communications)。URLLC业务的性能指标包括2个,分别是用户面平均时延和可靠性。对于用户面时延,上行和下行都是0.5ms平均时延,可靠性方面,要求在一定的信道条件下,对于给定大小的数据包在1ms内要实现99.999%的可靠传输。这将对URLLC业务提出具有更短的调度间隔的要求,例如采用125微秒作为一个时隙的长度,或者2个子载波间隔为15kHz的具有普通循环前缀(CP,Cyclic Prefix)的正交频分复用技术(OFDM,Orthogonal Frequency  Division Multiplexing)的长度为一个mini-slot(迷你时隙)的长度,这里的mini-slot作为一个URLLC业务的调度单元。
相关技术中,对于NR中的增强移动宽带业务主要用于提升网络容量(eMBB,enhanced Mobile BroadBand),其对时延的要求相比URLLC更宽松,上行和下行用户面平均时延都为4ms,因此,基站可以采用更长的调度间隔调度eMBB数据,从而减少频繁调度带来的控制信道开销。例如,采用一个或多个slot(时隙)作为具有第一eMBB的调度单元。
相关技术中,按照NR协议的规定,同一个UE是可以同时支持eMBB和URLLC业务,目前协议可以通过配置2个search space set(搜索空间集),一个用于eMBB业务一个用于URLLC业务,这时就可能出现一种情况,即一个UE在第一个search space set中监听PDCCH候选,当盲检测到物理下行控制信道(Physical Downlink Control Channel,PDCCH)后,进一步根据下行控制信息(Downlink Control Information,DCI)消息中的资源分配比特域指示的时频资源解调数据时,如果还有其他PDCCH候选,UE会进一步盲检PDCCH以防发生可能的突发,这时就会造成UE一边解调数据的同时还要盲检PDCCH,从而增加UE检测的复杂度;另外,目前NR协议中支持基于时隙(slot-based)的调度和跨slot调度,如果多次调度指向同一个slot会造成UE混淆。针对相关技术中存在的上述问题,目前尚未发现有效的解决方案。
