本发明实施例涉及通信技术领域，尤其涉及一种配置上下行子帧的方法及装置。Embodiments of the present invention relate to the field of communication technologies, and in particular to a method and device for configuring uplink and downlink subframes.
背景技术Background technique
随着互联网技术的发展，通信业务量会急剧增长，业务类型也会更加多变。在LAA微型小区的环境下，由于小区内用户数量较少，并且随着数据业务的发展，上下行业务具有突发性的特点，上下行业务之间很难保持一个稳定的业务比例。在这种情况下，现有的静态上下行子帧配置的方式，不能很好的适应这种业务突发性带来的变化，容易造成资源的浪费以及频谱效率的下降，并且也不能很好地发挥LAA基站的特点和优势。例如，如果当前时刻下行业务量远多于上行业务量，根据业务量情况将子帧配置为固定方式一，即[DSUDDDSUDD]，但在下一时刻可能上行业务量大大增加，远远超过下行业务量，当前的子帧配置就不能满足传输的要求。为了更好的解决业务的突发性带来问题，需要一种小区间灵活、自适应地上下行子帧配置方式。With the development of Internet technology, the volume of communication services will increase dramatically, and the types of services will become more varied. In the LAA micro-cell environment, due to the small number of users in the cell and the sudden nature of the uplink and downlink services with the development of data services, it is difficult to maintain a stable business ratio between the uplink and downlink services. In this case, the existing static uplink and downlink subframe configuration methods cannot well adapt to the changes brought about by the suddenness of such services, which is likely to cause waste of resources and decrease in spectrum efficiency, and it is also not very good. Give full play to the characteristics and advantages of the LAA base station. For example, if the downlink traffic is much more than the uplink traffic at the current moment, configure the subframe as fixed mode 1 according to the traffic situation, that is, [DSUDDDSUDD], but the uplink traffic may increase greatly at the next moment, far exceeding the downlink traffic , the current subframe configuration cannot meet the transmission requirements. In order to better solve the problem caused by the burstiness of services, a flexible and adaptive way of configuring uplink and downlink subframes between cells is needed.

Then, at the beginning of each TII, the uplink and downlink subframes are reconfigured according to the total number of uplink and downlink bits to be transmitted in the current TTI.
从TTI＝2时刻起，之后在每个TTI的起始时刻分别统计各LAA基站下的UE上行缓存待传比特数和下行缓存待传比特数，将上下行待传总比特数相比得到一个比值UL/DL，然后将这个比值UL/DL和一个对比参数m进行比较。若比值UL/DL>＝对比参数m,则将第N+4个TTI时刻的子帧设置为UL(N表示当前TTI)；若这个比值UL/DL<对比参数m，则N+4TTI子帧保持不变，仍为DL。对于这个对比参数m大小的取值，可以取为上下行泊松过程的lamda值的比例，即lamda_ul/lamda_dl。From TTI = 2, after that, at the beginning of each TTI, the number of uplink buffered bits to be transmitted and the number of downlink buffered bits to be transmitted by the UE under each LAA base station are counted, and the total number of uplink and downlink bits to be transmitted is compared to obtain a The ratio UL/DL is then compared with a comparison parameter m. If the ratio UL/DL>=comparison parameter m, then set the subframe at the N+4th TTI moment as UL (N indicates the current TTI); if the ratio UL/DL<comparison parameter m, then N+4TTI subframe Unchanged, still DL. For the value of the comparison parameter m, it can be taken as the ratio of the lamda value of the uplink and downlink Poisson processes, that is, lamda_ul/lamda_dl.
