  • the number of preambles in CBRA is too small, resulting in a high collision probability, or the RSRP threshold configured on the network side for 2-step CBRA is too low, resulting in too many terminals performing 2-step CBRA, and the collision probability is high.

  • the network side can determine whether it should support the terminal to fall back to the 4-step RACH. For example, in the edge coverage area on a certain carrier or BWP, the RSRP measured by the terminal is not very high. Therefore, the probability of failure of the 2-step RACH of the terminal in the edge area is high. If the terminal is not supported to fall back to the 4-step RACH, the terminal will not be able to complete the random access process.
  • the network side can determine whether the number of 2-step RACH attempts that the terminal is allowed to try is properly configured. If the number of times N is configured too large, it will cause the terminal to try too many 2-step RACHs, and eventually fall back to 4-step RACH, which will cause the terminal to try 2-step RACH for too long; if the number of times N is configured too much If it is small, it will cause the terminal to easily produce a fallback process, so that there are fewer terminals that can benefit from the 2-step RACH process.

Description

信息上报方法、接收方法装置、终端及网络侧设备
相关申请的交叉引用
本申请主张在2020年2月7日在中国提交的中国专利申请号No.202010082243.X的优先权,其全部内容通过引用包含于此。
技术领域
本公开涉及通信技术领域,尤其是指一种信息上报方法、接收方法装置、终端及网络侧设备。
背景技术
对于工作在免许可频段的终端和基站,必须在每次发送数据之前都要进行LBT(Listen before talk,先听后说)操作,如果监听到信道繁忙,则退避一段时间再监听,直到信道空闲一段时间后才可认为信道空闲,再发送数据。为了减少随机接入的时延,可以减少相关技术中的4步随机接入机制的步骤到2步,从而减少进行LBT的次数,实现减少随机接入的整体时延。
由于2步随机接入具有步骤少,时延短的优点,其应用场景也顺理成章地扩展到了许可频段。也就是说,免许可频段和许可频段都可使用2步随机接入。
此外,对于切换的场景,目标基站可以在切换命令中给终端配置专用的随机接入资源,以避免终端在目标小区的随机接入过程中与其他终端碰撞,从而提升终端接入目标小区的速度。
通常终端发起2步或4步随机接入时并未与网络建立连接,所以网络侧不了解终端的随机接入的性能情况;从而导致网络侧无法对网络覆盖或参数进行优化。

向终端发送用于请求终端上报随机接入的相关信息的请求消息。
作为本公开的至少一个实施例,所述向终端发送用于请求终端上报随机接入的相关信息的请求消息之前,所述方法还包括:
接收终端发送的指示信息,所述指示信息用于指示所述终端记录有随机接入的相关信息。
换言之,终端向网络侧设备上报随机接入的相关信息的方式包括下述三种:
1.网络侧通过请求消息请求终端上报;
2.终端主动上报;
3.终端告知网络其记录有随机接入的相关信息之后,网络侧再通过请求消息请求终端上报。
其中,所述随机接入的相关信息通过下述消息的至少一项消息携带:
目标消息;例如该目标消息为新定义的消息等,在此不做具体限定;
随机接入报告。
本公开的至少一个实施例中,上述随机接入的相关信息可以帮助网络侧在合适的载波(SUL/UL)、BWP上配置合理的随机接入类型(2步、4步、CBRA、CFRA)及相关的参数(2步随机接入的RSRP门限、尝试2步随机接入的次数等)。
网络侧设备接收到终端上报的随机接入的相关信息之后,可以进行相应 的网络覆盖及参数优化,如优化终端在SUL或UL、BWP上支持的随机接入类型、2步随机接入的质量门限值,尝试2步随机接入的次数门限、优化消息A对应的覆盖包括波束级别的和小区级别的覆盖优化等。例如:
1)根据终端上报的随机接入的相关信息,网络侧可以定位需要优化的随机接入的场景和类型,如发生随机接入失败的场景是切换场景下的2-step CFRA,终端没有正确地完成网络侧期待的2-step CFRA,原因可能是给终端分配的专用随机接入资源的随机接入前导preamble码与邻区的产生了碰撞,或给终端配置的进行2-step CFRA的RSRP的门限值过低、导致终端检测到的RSRP虽然符合网络侧配置的门限、但是基站侧没有成功检测到msg A(其中基站可能成功解出了preamble码,给终端回复fallback指示;也可能连preamble码都没有成功解出,网络侧给终端回复backoff指示),从而无法正常完成2-step CFRA过程。因此网络侧可以与邻区协调preamble的group避免碰撞(如当preamble码被成功解出时),或提升终端进行2-step CFRA的RSRP的门限值(如当preamble码没有被成功解出时),提升网络侧检测msgA的成功率。
2)根据终端上报的随机接入的相关信息,网络侧可以判断终端发送msg A之后收到对应反馈的时间长度,从而判断是否应提升某些场景、特别是CFRA这种对时延要求高的场景下的基站的反馈速度,避免终端长时间等待网络侧的反馈。
3)根据终端上报的随机接入的相关信息,例如终端发起了2-step CBRA、并检测到了碰撞,且网络侧收到多个终端的类似上报,则网络侧判断可能是分给2-step CBRA的preamble数太少了、导致碰撞概率较高,或者网络侧配置的进行2-step CBRA的RSRP的门限值过低、导致进行2-step CBRA的终端过多从而碰撞概率较高,因此网络侧可以调整终端进行2-step CBRA的RSRP的门限值和/或preamble group(前导码组)。
4)根据终端上报的随机接入的相关信息,网络侧可以进一步定位该随机接入的问题发生在哪个载波上(SUL还是普通的UL),以及哪个BWP上(网络侧可根据locationandbandwidth、子载波间隔SCS等信息判断具体的BWP),网络侧可以针对性地调整相应的载波或BWP的随机接入资源的配置,或调 整网络侧对终端选择SUL或UL的指示(当该载波上的SUL或UL是由网络侧指示、而非配置门限的形式);
5)根据终端上报的随机接入的相关信息,网络侧可以判断是否应该支持终端回退到4步RACH,如某个载波或BWP上的边缘覆盖地区,终端测量到的RSRP并不是很高,那么在边缘地区终端进行2-step RACH的失败概率较高,如果不支持终端回退到4步RACH,将导致终端无法完成随机接入过程。
6)根据终端上报的随机接入的相关信息,网络侧可以判断允许终端尝试的2-step RACH的次数是否配置合理。如次数N配置得过大,会导致终端尝试过多次数的2-step RACH、最终还是要回退到4-step RACH,导致终端尝试2-step RACH的时间过长;若次数N配置得过小,则会导致终端很容易就会产生回退过程、从而能从2-step RACH过程中获益的终端较少。
