Description

资源的确定方法、装置及通信设备Resource determination method, device and communication device 技术领域technical field
本公开涉及移动通信领域，特别是指一种资源的确定方法、装置及通信设备。The present disclosure relates to the field of mobile communications, and in particular, to a method, an apparatus, and a communication device for determining a resource.
背景技术Background technique
新一代的虚拟现实(virtual reality，简称VR)、增强现实(Augmented reality，简称AR)、车车通信等新型行业的不断涌现对于无线通信技术提出了更高的要求，驱使无线通信技术的不断演进以满足各行业应用的需求。The continuous emergence of new industries such as a new generation of virtual reality (VR), augmented reality (AR), and vehicle-to-vehicle communication has put forward higher requirements for wireless communication technology, driving the continuous evolution of wireless communication technology. To meet the needs of applications in various industries.
在无线通信技术的研究中，非地面网络通信***(Non-Terrestrial Network，简称NTN)，比如卫星通信，被认为是未来无线通信技术发展的一个重要方面。卫星通信是指地面上的无线电通信设备利用卫星作为中继节点而进行的通信。卫星通信***由卫星部分和地面部分组成。卫星通信的特点是：通信范围大，只要在卫星发射的电波所覆盖的范围内，从任何两点之间都可进行通信，不易受陆地灾害的影响，可靠性高。In the research of wireless communication technology, non-terrestrial network communication system (Non-Terrestrial Network, NTN for short), such as satellite communication, is considered to be an important aspect of the future development of wireless communication technology. Satellite communication refers to the communication carried out by radio communication equipment on the ground using satellites as relay nodes. The satellite communication system consists of a satellite part and a ground part. The characteristics of satellite communication are: the communication range is large, as long as the radio waves emitted by the satellite cover the range, communication can be carried out from any two points, it is not easily affected by land disasters, and the reliability is high.
在偏远的没有蜂窝网络覆盖的区域，新型行业需求也很强烈，比如，在运输(海运，陆路，铁路，航空)和物流、环境检测、采矿等行业方面。长期演进技术(Long-Term Evolution，简称LTE)、增强的机器类型通信(enhanced Machine Type Communication，简称eMTC)非常适合上述行业应用，但是需要通过卫星连接才能提供覆盖。There is also strong demand for new industries in remote areas without cellular coverage, for example, in transportation (sea, land, rail, air) and logistics, environmental testing, mining and other industries. Long-Term Evolution (LTE) and enhanced Machine Type Communication (eMTC) are very suitable for the above-mentioned industry applications, but satellite connections are required to provide coverage.
相关技术中，LTE/eMTC***中，对同一小区或用户设备UE，用于下行同步和广播信息接收的时频域资源较为固定，无法灵活配置，无法适应波束赋形、波束扫描，导致无法实现LTE/eMTC的覆盖增强。In the related art, in the LTE/eMTC system, for the same cell or user equipment UE, the time-frequency domain resources used for downlink synchronization and broadcast information reception are relatively fixed, which cannot be flexibly configured, and cannot be adapted to beamforming and beam scanning. Coverage enhancement of LTE/eMTC.

需要说明的是，由于不同的第一产生参数对应不同的候选PSS，从而UE可根据与获取的PSS相关的任一候选PSS对应的第一产生参数，作为该获取的PSS对应的第一产生参数，即作为该获取的PSS所在的下行传输的组序号。It should be noted that, since different first generation parameters correspond to different candidate PSSs, the UE can use the first generation parameter corresponding to any candidate PSS related to the acquired PSS as the first generation parameter corresponding to the acquired PSS , that is, the group sequence number of the downlink transmission where the obtained PSS is located.
其中，候选PSS与获取的PSS的相关性可以通过任一可衡量两个信号间关系的方式确定。可以本公开对此不做限定。The correlation between the candidate PSS and the acquired PSS can be determined by any method that can measure the relationship between the two signals. The present disclosure may not limit this.

需要说明的是，由于不同候选SSS对应不同的第二产生参数，从而UE可根据与获取的SSS相关性的任一候选SSS对应的第一产生参数，作为该获取的SSS对应的第一产生参数，进而确定该获取的SSS所在的下行传输的组序号。It should be noted that, since different candidate SSSs correspond to different second generation parameters, the UE can use the first generation parameter corresponding to any candidate SSS related to the acquired SSS as the first generation parameter corresponding to the acquired SSS , and then determine the group sequence number of the downlink transmission where the acquired SSS is located.
其中，候选SSS与获取的SSS的相关性可以通过任一可衡量两个信号间关系的方式确定，本公开对 此不做限定。Wherein, the correlation between the candidate SSS and the acquired SSS can be determined by any method that can measure the relationship between the two signals, which is not limited in the present disclosure.

其中，不同的PBCH对应的加扰序列和/或第三产生参数不同，第三产生参数，为用于产生加扰序列的参数，不同的第三产生参数，对应不同的加扰序列，进而对应不同的PBCH。即不同的下行传输，对应不同的第三产生参数或者不同的加扰序列。该加扰序列和/或第三产生参数，可以是网络设备预先发送给UE的，或者，还可以是UE基于协议或者标准的约定确定的，本公开对此不做限定。Wherein, the scrambling sequences and/or the third generation parameters corresponding to different PBCHs are different, the third generation parameters are parameters used to generate the scrambling sequences, and the different third generation parameters correspond to different scrambling sequences, which in turn correspond to different PBCHs. That is, different downlink transmissions correspond to different third generation parameters or different scrambling sequences. The scrambling sequence and/or the third generation parameter may be pre-sent by the network device to the UE, or may be determined by the UE based on a protocol or a standard agreement, which is not limited in the present disclosure.
另外，加扰序列的生成规则也可以是网络设备预先发送给UE的，或者，还可以是UE基于协议或者标准的约定确定的，本公开对此不做限定。In addition, the generation rule of the scrambling sequence may also be pre-sent by the network device to the UE, or may also be determined by the UE based on an agreement of a protocol or standard, which is not limited in the present disclosure.
可选的，若网络设备为UE配置了各第三产生参数及加扰序列的生成规则，或者，UE基于协议或者标准的约定，可以确定各第三产生参数及加扰序列生成规则，那么UE即可以根据加扰序列的生成规则及各第三产生参数，生成PBCH的各候选加扰序列，然后再基于候选加扰序列，获取PBCH。Optionally, if the network device configures each third generation parameter and the scrambling sequence generation rule for the UE, or the UE can determine each third generation parameter and the scrambling sequence generation rule based on the agreement of the protocol or standard, then the UE can determine the third generation parameter and the scrambling sequence generation rule. That is, each candidate scrambling sequence of the PBCH can be generated according to the generation rule of the scrambling sequence and each third generation parameter, and then the PBCH can be obtained based on the candidate scrambling sequence.
通常，网络设备在发送下行传输时，为提高信号的抗干扰性，会先用加扰序列对下行传输进行加扰，之后再将加扰后的下行传输发送给UE。相应的，UE可基于已知的各加扰序列对各下行传输进行尝试接收，若接收成功，则可以确定接收的该下行传输对应的加扰序列为当前使用的加扰序列。而如果接收失败，则丢弃该下行传输。Generally, in order to improve the anti-interference of the signal when sending the downlink transmission, the network device first scrambles the downlink transmission with a scrambling sequence, and then sends the scrambled downlink transmission to the UE. Correspondingly, the UE may attempt to receive each downlink transmission based on each known scrambling sequence, and if the reception is successful, the UE may determine that the received scrambling sequence corresponding to the downlink transmission is the currently used scrambling sequence. And if the reception fails, the downlink transmission is discarded.
需要说明的是，本公开中，对于PSS、SSS及PBCH对应的加扰序列的生成规则，可以分别采用相关协议中的产生公式，也可以是预先设定的其它生成规则对应的公式，本公开中对此不作限定。It should be noted that, in the present disclosure, for the generation rules of the scrambling sequences corresponding to PSS, SSS and PBCH, the generation formulas in the relevant protocols can be used respectively, or the formulas corresponding to other preset generation rules can be used. is not limited in this regard.
