  • the primary synchronization signal mainly performs time domain synchronization and frequency domain synchronization synchronization at the sub-frame level, and the base station transmits a 62-bit ZC sequence (Zadoff).
  • -Chu sequence there are three kinds of root sequences, because there is enough spread spectrum gain, and the path loss of low frequency transmission is not particularly large, which can meet the requirements of 4G; the secondary synchronization signal can further complete the synchronization of the wireless frame level.
  • the subframe number information may further acquire physical cell ID information.
  • the synchronization signal uses a relatively fixed transmission mode; because the user equipment (User Equipment, UE for short) It can be called terminal). It does not know the bandwidth of the cell system when booting. It only knows the frequency band and bandwidth that it supports (see 36.101 for details). In order to enable the UE to detect the frequency and symbol synchronization information of the system as soon as possible, regardless of the size of the downlink system bandwidth, the PSS and the SSS are located on the central 72 subcarriers (ie, the central resource block (Resource Block, RB for short) ), does not contain DC.
  • the central 72 subcarriers ie, the central resource block (Resource Block, RB for short)
  • the UE will attempt to receive PSS and SSS near the center frequency of the LTE frequency it supports. Since the terminal cannot obtain the configuration information related to the subframe, the time domain position of the synchronization signal PSS/SS and the broadcast channel PBCH is relatively fixed for a duplex mode, as shown in FIG. 1 .
  • FIG. 2 For the basic process of synchronization in LTE and the functions of each step, refer to FIG. 2 .

  • frequency bands are mainly 3GHz to 6GHz and 6GHz to 100GHz.
  • This frequency band basically belongs to the centimeter band and the millimeter band, and its propagation characteristics are significantly different from the lower frequency band. Since the propagation loss of the high frequency band is significantly larger than the low frequency band, the coverage of the high frequency band is generally much smaller than the coverage of the low frequency band.
  • beamforming technology is generally used in transmission to narrow the wireless signal energy and concentrate on devices that need to communicate with each other. For the synchronization signal, through some calculations and analysis, it is considered that a narrow beam is needed to effectively combat very large path loss, so that the SINR of the receiving end satisfies the synchronous coverage requirement.
  • the original synchronization signal that only needs one wide beam covers the entire cell, and becomes a synchronization signal that needs multiple narrow beams, as shown in FIG.
  • the narrow beam synchronization signal coverage technology introduces a new dimension into the air domain, and the number of beams is N, and N is an integer greater than 1.
  • the challenge of the beam-based synchronization signal is: since many beams formed when the number of antennas is large are radio frequency beams, different radio beams formed by the same transmission channel cannot perform space division multiplexing and frequency division multiplexing; different coverage The situation and the value of the different beamwidth conditions N are not fixed, which brings great difficulty to the detection of the synchronization signal.
  • different radio frequency beams are mainly time-division multiplexed, and different radio frequency beams are transmitted on different time domain symbols. If the radio frequency beam is used for the synchronization signal, the wide beam synchronization signal becomes multiple narrow beam synchronization. Signal transmission. At this time, there is a problem that when the number of beams is different, the time domain resources that need to be occupied are different, but in the related art, at this time The terminal does not complete the access, and cannot notify the information about the value of the number of radio beams when the synchronization is synchronized. Therefore, in the related art, a fixed value of N is adopted, which greatly limits the flexibility of synchronization, thus affecting the performance of synchronization and the coverage of synchronization signals.

Description

同步信号的发送方法、接收方法、发送装置及接收装置 技术领域
本发明涉及通信领域，具体而言，涉及一种同步信号的发送方法、接收方法、发送装置及接收装置。
背景技术
通信系统中一个重要的基础性问题是同步问题；同步的主要功能是完成通信时间上的同步和频域上的同步(多载波系统)，使得待同步的对端(可以是基站，也可以是终端，下面以终端为例进行说明)可以正确的进行物理层各信道及信号的接收；同步检测过程中还可以获取一些其他的必要信息，比如通知物理层小区标识(Physical-layer Cell Identity，简称为PCI)等。在4G长期演进(Long-Term Evolution，简称为LTE)中，由于主要工作在低频，物理层同步信号在空域上是在较宽的范围内发送，分为主同步信号(Primary Synchronization Signal，简称为PSS)和辅同步信号(Secondary Synchronization Signal，简称为SSS)；其中主同步信号主要完成子帧级的时域同步及频域同步的同步功能，基站发送时采用一个62位长的ZC序列(Zadoff-Chu序列)，有三种根序列可选，由于存在足够的扩频增益，而且低频传输的路径损耗不是特别大，可以满足4G的需求；辅同步信号可以进一步的完成无线帧级的同步，获得子帧编号信息，还可以进一步的获取物理小区ID信息。
终端开机后在同步信号的检测之前，由于终端不能获得带宽、双工方式、天线数目相关的信息，因此同步信号采用的是比较固定的发送方式；由于用户设备(User Equipment，简称为UE，也可称为终端)开机时并不知道小区系统带宽的大小，只知道自己支持的频带和带宽(详见36.101)。为了使UE能够尽快检测到系统的频率和符号同步信息，无论下行系统带宽的大小是多少，PSS和SSS都位于中心的72个子载波上(即中心的6个资源块(Resource Block，简称为RB)上，不包含DC。实际只使用了 频率中心DC周围的62个子载波，两边各留了5个子载波用作保护波段)。UE会在其支持的LTE频率的中心频点附近去尝试接收PSS和SSS。由于终端不能获取子帧相关的配置信息，因此对于一种双工方式，其同步信号PSS/SS及广播信道PBCH的时域位置是比较固定配置的，如图1所示。LTE中同步基本流程及各步骤功能具体可参见图2。
新一代的5G移动通信系统将会在比2G、3G、4G系统所用频率更高的载波频率上进行系统组网，目前得到业界广泛共识和国际组织认定的频段主要是3GHz～6GHz和6GHz～100GHz，这一频段基本上属于厘米波段和毫米波段，其传播特性与较低频段有明显区别，由于高频段的传播损耗明显大于低频段，因此高频段的覆盖一般远小于低频段的覆盖范围。为了增强高频段的覆盖范围，发送时普遍采用了波束成型技术，使无线信号能量收窄，更集中于需要相互通信的设备上。对于同步信号，通过一些计算和分析，认为需要使用窄波束才能有效的对抗非常大的路径损耗，使得接收端的SINR满足同步的覆盖需求。
在同步过程中引入射频波束后，原来的只需要一个宽波束的同步信号覆盖整个小区，变为了需要多个窄波束的同步信号的进行发送，如图3所示。
相比于原来的宽波束同步信号覆盖技术，窄波束的同步信号覆盖技术引入了一个新的维度为空域，其波束个数为N，N为大于1的整数。此时基于波束的同步信号面临的挑战有：由于天线数目很多时形成的很多波束是射频波束，同一个发送通道形成的不同的射频波束不能进行空分复用和频分复用；不同的覆盖情况以及不同的波束宽度情况N的取值不固定，给同步信号的检测带来较大的困难。
相关技术中，不同的射频波束主要是通过时分复用的，不同的射频波束在不同时域符号上发送，如果射频波束用于同步信号，则宽波束的同步信号变为多个窄波束同步的信号发送。此时，存在的一个问题是，在波束个数不同时，其需要占用的时域资源是不同的，但是在相关技术中，此时 终端并没有完成接入，无法通知相关的同步时射频波束个数的取值N的信息。因此在相关技术会采用固定的N的取值，这样会大大限制同步的灵活性，因此影响了同步的性能及同步信号的覆盖。
针对上述问题，相关技术中并未提出有效的解决方案。
