技术领域Technical field
本发明涉及通信技术领域,尤其涉及一种NR-U系统中的系统信息传输方法。The present invention relates to the field of communication technology, and in particular, to a system information transmission method in an NR-U system.
背景技术Background technique
在移动通信领域,频谱资源是推动产业发展的核心资源,且随着移动通信的快速发展,频谱资源短缺的问题日益凸显。为解决这个问题,一方面采用大规模天线(MassiveMIMO)、超密集组网(UDN)等新技术提升网络容量,另一方面,不断开发可用的频谱资源。In the field of mobile communications, spectrum resources are the core resource that promotes industrial development. With the rapid development of mobile communications, the problem of spectrum resource shortage has become increasingly prominent. In order to solve this problem, on the one hand, new technologies such as massive antennas (MassiveMIMO) and ultra-dense networking (UDN) are used to improve network capacity; on the other hand, available spectrum resources are continuously developed.
目前5GHz频段存在的免许可使用的非授权频段仍是值得挖掘的资源。为了能够使用该非授权频段,3GPP提出了辅助授权接入(LAA)技术,即采用载波聚合的方式把非授权频段和授权频段联合进行使用,以实现更高的数据速率,使用户感受到更好的应用体验。然而,由于WiFi网络部署也在非授权频段,将新空口(NR)技术直接应用于非授权频段将不可避免地对Wi-Fi造成干扰。因此,在数据传输之前,基站需要首先执行先听后说(LBT)操作,以选择可用的频谱资源,最终实现和WiFi的和谐共存。The unlicensed frequency bands that currently exist in the 5GHz frequency band without permission are still resources worth exploring. In order to be able to use this unlicensed frequency band, 3GPP proposed assisted licensed access (LAA) technology, which uses carrier aggregation to jointly use unlicensed frequency bands and licensed frequency bands to achieve higher data rates and make users feel more comfortable. Good application experience. However, since WiFi network deployment is also in unlicensed frequency bands, applying New Radio (NR) technology directly to unlicensed frequency bands will inevitably cause interference to Wi-Fi. Therefore, before data transmission, the base station needs to first perform a listen-before-talk (LBT) operation to select available spectrum resources and ultimately achieve harmonious coexistence with WiFi.
在LTE中,系统信息(SI)是小区级别的信息,即对接入该小区的所有终端(UE)生效。它包含3种类型的RRC消息用于传输SI,分别是MIB消息、SIB1消息、一个或多个SI消息。然而,在NR中,为降低SI广播开销,有两种不同类型的SIB:一种类型是像LTE中SIB一样周期性地发送的类型,另一种类型是仅在有来自UE的请求时发送的类型,即引入了SI请求功能。In LTE, system information (SI) is cell-level information, which is effective for all terminals (UE) accessing the cell. It contains three types of RRC messages for transmitting SI, namely MIB messages, SIB1 messages, and one or more SI messages. However, in NR, to reduce SI broadcast overhead, there are two different types of SIB: one type is sent periodically like SIB in LTE, and the other type is sent only when there is a request from the UE type, that is, the SI request function is introduced.
对于SI请求,在NR中,主要有两种请求方法,分别是通过msg1和msg3进行SI请求。对于msg1请求SI,主要是通过RRC配置专有的PRACH occasion实现的,而对于msg3请求SI,主要是通过RRCSystemInfoRequest消息请求SI。此外,基于两步随机接入msgA也可以发起SI请求,相关内容仍然在讨论中。然而在新空口免授权频谱(NR-U)系统中,由于信道状态的不确定性,可能会存在请求SI不成功的情形,此时,UE则需要等待下一个周期在SI窗口接收请求的SI,这引入较大的等待时延,严重影响系统性能,因此,如何在NR-U系统中成功地,并且高效地获取SI是目前需要解决的重要问题。For SI requests, in NR, there are two main request methods, namely SI requests through msg1 and msg3. For msg1 to request SI, it is mainly implemented through the RRC configuration-specific PRACH occasion, while for msg3 to request SI, it is mainly requested for SI through the RRCSystemInfoRequest message. In addition, SI requests can also be initiated based on two-step random access msgA, and related content is still under discussion. However, in the New Radio Unlicensed Spectrum (NR-U) system, due to the uncertainty of the channel state, there may be situations where the SI request is unsuccessful. At this time, the UE needs to wait for the next cycle to receive the requested SI in the SI window. , which introduces a large waiting delay and seriously affects system performance. Therefore, how to successfully and efficiently obtain SI in the NR-U system is an important issue that needs to be solved at present.
