  • the industry's vision for 5G systems is to deliver any data to anyone or thing at any place and time. It is foreseeable that 5G will inevitably penetrate all aspects from production to life, providing the necessary material basis for industrial and social transformation and change.
  • the 5G communication system design requires much higher throughput, the number of connected terminals, delay, mobility, energy consumption and network flexibility than the previous communication system, and the system design will face more challenges.
  • One of the main challenges is to reduce network energy consumption, especially for base stations.
  • the communication system focused on reducing the energy consumption on the terminal side to extend the standby and use time of the terminal. Due to the more reliable power supply and technical considerations of the base station, the energy consumption of the base station has not received much attention. From the statistics, the current electricity cost of the base station under the system is a very important expenditure cost.
  • 5G In order to meet the needs of a variety of wireless services, 5G needs to have higher throughput and requires wider bandwidth. However, the traditional 300MHz to 3GHz frequency band cannot provide more bandwidth resources, so 5G will adopt more than before. Higher frequency bands in communication systems, such as 45 GHz and 60 GHz, have disadvantages such as large free propagation loss and easy absorption by air and rain. In urban and suburban areas, in order to meet the coverage and throughput requirements, 5G will adopt a multi-base station dense network (UDN). The density of base stations will far exceed that of previous communication systems. It can be expected if The energy consumption of the base station in 5G is still the same or similar to that of the previous communication system.
  • UDN multi-base station dense network
  • base station In order to communicate the target at any place, the base station is needed. Covering remote areas with sparsely populated areas, base stations in these areas are mostly powered by emerging energy sources such as solar energy. Base stations have lower energy consumption, making solar panels smaller, reducing the cost of base stations, and utilizing base stations. Deploy to these areas.
  • the bearer traffic of each base station is not evenly distributed, and is close to the "80/20 law".
  • a small number of base stations carry a large amount of services of the entire network, and most of the base stations only carry a small amount of the entire network.
  • the time-frequency resource utilization of base stations carrying a large number of services is at least double that of a small number of service base stations, but the energy consumption of the former is far less than double that of the latter, and the traffic volume is greatly different. The difference in energy consumption is reduced.
  • the main reason is the transmission of non-service data for cell discovery and access. Such data is frequently sent in a certain period regardless of whether the base station has services. The system broadcast message is such data. An important class.
  • 5G will avoid adopting the cyclical mode. It will use the “on-demand” method to send system broadcast messages, that is, transmit system broadcast messages only when the terminal needs it, and the higher frequency band adopted by 5G has shorter wavelengths, which can be used in units. Having more antennas in the area means that data can be transmitted by beamforming. This way, the transmission energy is concentrated in one direction, while the other directions have little or no energy. The on-demand transmission can be extended to space in this way. on.

Description

一种***广播消息的传输方法及基站、终端 技术领域
本发明涉及高频通信***领域，具体地说，涉及高频通信中一种***广播消息的传输方法及基站、终端。
背景技术
随着各种各样的无线电业务需求大量涌现，5G(第五代通信***)作为下一代通信***被提出。业界对5G***愿景为在任何地点和时间下任何人或物传递任何数据，可预见5G必将渗透到从生产到生活的各个方面，为工业和社会的转型和变革提供必要的物质基础，因此5G通信***设计在吞吐率、连接终端的数量、延迟、移动性、能耗和网络灵活性等各方面要求都要远高于之前的通信***，***设计将面临更多的挑战。
面临的主要挑战的之一是降低网络能耗，特别是基站的能耗问题。之前通信***着重降低终端侧的能耗，以延长终端的待机和使用时间，由于基站供电更有保证及技术方面考虑，基站的能耗没有受到重点关注。从统计看，目前***下基站的电费是十分重要的支出成本。
5G为了满足多种多样无线业务需求，需要有更高的吞吐率，要求有更宽的带宽，而传统使用的300MHz～3GHz的频段上已无法提供更多的带宽资源，因此5G将采用比之前通信***更高的频段，如45GHz、60GHz等，这些高频段信道具有自由传播损耗大、容易被空气和雨水吸收等缺点。在城区和郊区，为了达到覆盖和吞吐率方面的需求，5G会采用多基站密集组网(Ultra Dense Network，简称UDN)的方式，基站的密集程度会远超之前的通信***，可以预期，如果5G中基站的能耗依然和之前的通信***相同或类似，那基站电费的支出对运行商而言将不可承受，且不符合节能减排的全球共识，同时为了在任何地点通信目标，需要基站覆盖人烟稀少的偏远地区，这些地区的基站多采用如太阳能等新兴能源供电，基站有较低的能耗，使得太阳能电池板更小，降低了基站的成本，有利用基站 部署到这些地区。
现有通信***下，各基站承载业务量不是均匀分布，趋近于“80/20定律”，约少部分的基站承载了整网大量的业务，而大部分的基站仅承载了整网少量的业务；从使用的资源和能耗角度，承载大量业务的基站时频资源利用率至少是承载少量业务基站的一倍，但前者能耗远远达不到后者的一倍，业务量差异大，而能耗差异反倒减小，主要的原因是用于小区发现和接入的非业务数据的发送，这类数据无论基站是否有业务都以一定周期频繁发送，***广播消息就是这类数据中的重要一类。为了降低能耗，5G将避免采用周期方式，会采用“按需”方式发送***广播消息，即只在终端需要时传输***广播消息，同时5G采用的更高频段有更短波长，可以在单位面积上容纳更多天线，意味着可以采用波束赋形方式传输数据，这种方式将传输能量集中于某一方向，而其他方向能量很少或没有，按需传输可利用这种方式拓展到空间上。鉴于此，如何利用波束实现在时间和空间上按需可靠传输***广播消息是需要解决的问题。

图5为本发明实施例对用的应用场景的示意图，其中高频基站通过B0到B6波束覆盖Cell1小区，而初始接入小区的终端UE1和UE2分别位于波束B1和B3方向上。下面结合应用场景及具体实施例对本发明进 行详细说明。
实施例一
图6为本发明实施例一的一种***广播消息的传输方法的流程图，本实施例中，把***广播消息分为三类：第一类***广播消息包含小区选择、小区接入等所有终端都需要的基础性消息；第二类***广播消息是指除第一类***广播消息外所有终端都需要的其他***广播消息，如信道通用配置参数、定时器常量等；第三类***广播消息跟终端状态相关，当终端所处的状态不同时，需要不同部分的第三类***广播消息，如小区重选相关参数等。
第一类***广播消息采用周期方式在B0到B6波束上发送，而第二类和第三类***广播消息采用本发明实施例中的按需方式发送，第二类和第三类***广播消息分别按本发明实施例中所述的变更周期的方式进行分类并封装进***消息块中，同时为第二类和第三类***广播消息分别配置第一和第二专用序列集，每个专用序列集进一步分割成不同子集，每个子集至少包含一个序列，各子集一一映射到各波束上(B0到B6)，产生专用序列集的方法是唯一固定的，而各序列集分割成子集方式及子集到波束的映射方式虽是固定的，但存在多个备选方案，序列集产生方法的参数、选用哪种分割和一一映射方法等信息包含在第一类***广播消息中。
本实施例中预留资源持续以固定的周期出现，预留的资源在频域上是离散的，终端接入小区前预先知道预留资源周期和频域位置。本实施例侧重于描述第二类和第三类***广播消息的传输过程，***广播消息的发送和接收的具体过程描述如下：
步骤101：基站BS在所有波束方向上按一定周期发送第一类***广播消息；
步骤102：终端UE2在波束B3方向上接收到基站BS发送的第一类***广播消息；
步骤103：终端UE2在紧邻的预留资源上向基站BS发送第二类*** 广播消息请求序列；
终端通过第一类***广播消息中相关参数，产生专用序列集、并进行子集分割和映射。
终端UE2从映射到波束B3上的第一专用序列集的子集中的随机选择一个序列作为发送的请求序列。
步骤104：基站BS在预留资源上接收到请求序列后，在波束B3方向上发送终端UE2所需的第二类***广播消息；
基站BS根据接收的序列所属类别判定所要发送***广播消息的类别，再根据序列所属子集判定发送的波束方向。
需要注意的是，第一专用序列集不区分初传和重传功能，因此基站BS只要接收到该类序列后，就将第二类***广播消息在指定的波束方向上全部发送一次。
步骤105：终端UE2在波束B3方向上接收基站BS发送的第二类***广播消息；
终端UE2通过控制信道上的信息获知***广播消息的编码和调制方式，及时频域位置。
终端UE2收到***广播消息后，通过接收的消息中的索引块信息判定消息是否包含所需的第二类***广播消息，如果包含所需消息，则完成第二类***广播消息的接收，直接进行步骤106。
终端UE2接收第二类***广播消息，如果在一段时间内没有接受到或没有正确接收到所需第二类***广播消息，则终端UE2则按步骤103中的方式重新发送请求序列。
步骤106：终端UE2进行随机接入过程并接入Cell1小区；
步骤107：接入小区后，基站BS根据终端UE2的状态择机主动发送终端UE2所需第三类***广播消息；
基站BS事先通过控制信道信息通知终端UE2基站将发送第三类*** 广播消息。
如果基站BS发送完终端UE2所需的第三类***广播消息后，在预留资源上检测到终端UE2重传请求序列，则基站BS将上次发送给终端UE2的第三类***广播消息重新发送一次。
值得注意的是，不同波束方向上的终端可能需要不同的第三类***广播消息，基站BS可以根据各波束方向上终端的需求，在各波束方向上传输不同的第三类***广播消息，由索引块标识具体每个波束方向上传输了哪些消息。
步骤108：终端UE2接收基站BS发送的第三类***广播信息，处理过程与步骤105类似，不再赘述，唯一不用之处在于反馈序列采用的是第二专用序列集；
步骤109：接收第三类***信息。
***广播消息变化时，基站BS采用以下两种方式之一向终端UE2发送***消息更新通知：1、通过Paging(寻呼)信息通知；2、通过第一类***广播消息通知；
基站BS在终端UE2所在的波束B3方向上统一发送第二类和第三类***广播消息中被更新的部分，没有更新的部分不发送，具体发送了哪些部分由索引块标识；
值得注意的是，如果波束B3方向上同时需要为其他终端传输其他部分***广播消息，则该部分消息可以和上述更新的消息合并在一起传输，由终端根据索引块信息及自身需求决定取用哪部分***广播消息。
终端UE2接收被更新的***广播信息，处理过程与步骤105类似，不再赘述。唯一不用之处在于采用的反馈序列，这里复用的是第二专用序列集，基站BS根据反馈的序列所属类别和历史传输记录，就可确定需要重传哪部分消息。
实施例二
图7为本发明实施例二的一种***广播消息的传输方法的流程图，该方法把***广播消息分为两类：第一类***广播消息包含小区选择、小区接入、随机接入等所有终端都需要的基础性消息；第二类***广播消息是指除第一类***广播消息外的其余***广播消息，如信道通用配置参数、定时器常量、小区重选相关参数等。
第一类***广播消息采用周期方式在B0到B6波束上发送，而第二类***广播消息采用本发明实施例中的按需方式发送，第二类***广播消息分别按本发明实施例中所述的变更周期的方式进行分类并封装进***消息块中。
本实施例中预留的资源仅在一段时间内以周期的方式的重复出现，预留资源的周期是动态调整的，预留的资源在频域上的位置是连续的，但可动态调整。预留的资源被分成编号0到6共7个部分，每个部分依据编号映射到波束上(B0到B6)，周期相关信息、预留资源分割和映射信息包含在第一类***广播消息中。本实施例侧重于描述第二类***广播消息的传输过程，***广播消息的发送和接收的具体过程描述如下：
步骤201：基站BS在所有波束方向上按一定周期发送第一类***广播消息；
步骤202：终端UE1在波束B1方向上接收到基站BS发送的第一类***广播消息；
步骤203：终端UE1进行随机接入过程并接入Cell1小区；
步骤204：接入小区后，基站BS通过控制信道信息通知终端UE1基站将发送第二类***广播消息，还告知预留资源出现周期，起始和终止时的***帧号，及在频域上的位置；
值得注意的是，各次通知的预留资源的周期和频域上位置可以根据实际情况动态改变。
步骤205：基站BS主动在波束B1方向上发送终端UE1必需的第二类***广播消息；
基站不发送的全部的第二类***广播消息，只发送包括信道通用配置参数、定时器常量等终端UE1维持正常业务所必需的信息，发送内容由索引块信息标识。
步骤206：终端UE1在波束B1方向上接收基站BS发送的第二类***广播消息；
终端UE1通过控制信道上的信息获知***广播消息的编码和调制方式，及时频资源位置。
终端UE1收到***广播消息后，通过接收的消息中的索引块信息判定消息是否包含所需的***广播消息，如果包含所需消息，则完成***广播消息的接收。
终端UE1没有收到或正确收到所需的第二类***广播消失时，在紧邻的预留资源中波束B1所对应的频域位置上发送具有一定能量的信号；
当基站BS在预留资源上检测到超过给定阈值的能量时，在波束B1方向上向终端UE1重传第二类***广播消息，终端按步骤206接收消息。
基站BS根据检测到的能量所在的频域位置判断出波束B1方向，再根据历史传输记录确定需要重传哪部分第二类***广播消息。
终端UE1的状态发生变化时，基站BS根据终端UE1的状态再向其发送所需的第二类***广播消息(如小区重选信息)，区别在于发送的内容不同；
当***广播消息需要更新时，基站BS采用以下两种方式之一向终端UE1发送***消息更新通知：1、通过寻呼信息通知；2、通过第一类***广播消息通知。基站BS还通过控制信道告知预留资源出现周期，起始和终止时的***帧号，及在时频域上的位置；
基站BS在波束B1方向上向在终端UE1发送第二类***广播消息中被更新的部分，没有更新的部分不发送，具体发送了哪些部分由索引块标识；
值得注意的是，如果波束B1方向上同时需要为其他终端传输其他部分的第二类***广播消息，则该部分消息可以和上述更新的消息合并在一起传输，由终端根据索引块信息及自身需求决定取用哪部分***广播消息。
终端UE1接收被更新的***广播信息，处理过程与步骤206相同。
实施例三
图8为本发明实施例三的一种***广播消息传输的方法的流程图，该方法把***广播消息分为两类：第一类***广播消息包含小区选择、小区接入、随机接入等所有终端都需要的基础性消息；第二类***广播消息是指除第一类***广播消息外的其余***广播消息，如信道通用配置参数、定时器常量、小区重选相关参数等。
第一类和第二类***广播消息采用本发明中的按需方式发送，且这两类广播消息分别按本发明实施例中所述的变更周期的方式进行分类并封装进***消息块中。
本实施例中预留资源持续以固定的周期出现，并且预留资源在频域上分为是离散的两部分，终端接入小区前预先知道预留资源的周期和在频域上的位置，第一部分预留资源被基站内所有终端共享，用于传输表示第一类***广播消息的能量信号，第二部分预留资源用于传输表示第二类***广播消息的专用序列集，此专用序列集及其分割和映射方式预先指定，作为基站和终端先验信息。***广播消息的发送和接收的具体过程描述如下：
步骤301：终端UE1完成同步过程后，首先随机等待一段时间，在等待的时间段内，尝试在指定的时频资源下按指定的编码和调制方式接收第一类***广播消息，如果接收到，则跳至步骤306，否则进行步骤302；
等待时间到达后，终端UE1在紧邻的第一部分预留资源上发送有一定能量的信号；
步骤302：基站BS1在第一部分预留资源上检测到超过一定阈值的能量后，按一定顺序在所有波束(B0到B1)方向上遍历传输第一类***广播消息一次；
第一类***广播消息采用固定的编码和调制方式，并在固定的时频资源上发送。
步骤303：终端UE1在波束B1方向上接收基站BS发送的第一类***广播消息；
终端UE1收到***广播消息后，通过接收的消息中的索引块信息判定消息是否包含所需的***广播消息，如果包含所需消息，则完成***广播消息的接收，跳至步骤304。终端UE1没有收到或正确收到第一类***广播消息时，在紧邻的第一部分预留资源上发送具有一定能量的信号，基站BS按步骤302处理；
步骤304：终端UE1进行随机接入过程并接入Cell1小区；
步骤305：接入小区后，基站BS通过控制信道信息通知终端UE1基站将发送第二类***广播消息；基站BS主动在波束B1方向上发送终端UE1必需的第二类***广播消息；
基站不发送的全部的第二类***广播消息，只发送包括信道通用配置参数、定时器常量等终端UE1维持正常业务所必需的信息，发送内容由索引块信息标识。
步骤306：终端UE1在波束B1方向上接收基站BS发送的第二类***广播消息；
终端UE1从控制信道上获取***广播消息的编码和调制方式及时频域位置。
终端UE1收到***广播消息后，通过接收的消息中的索引块信息判定消息是否包含所需的***广播消息，如果包含所需消息，则完成***广播消息的接收。
终端UE1没有收到或正确收到所需的***广播消失时，从波束B1所对应的专用序列子集中随机选择一个序列，并在紧邻的第二部分预留资源中发送。
当基站BS在第二部分预留资源上检测到序列时，在波束B1方向上向终端UE1重传第二类***广播消息；
基站BS根据检测到的序列判断出波束B1方向，再根据历史传输记录确定需要重传哪部分第二类***广播消息。
终端UE1的状态发生变化时，基站BS根据终端UE1的状态再向其发送此状态下所需的第二类***广播消息(如小区重选信息)，发送和接收的方式与上文类似，区别在于发送的内容不同；
***广播消息更新时，基站BS通过寻呼信息通知向终端UE1发送***消息更新通知；
基站BS在波束B1方向上统一向在终端UE1发送第一类和第二类***广播消息中被更新的部分，没有更新的部分不发送，具体发送了哪些部分由索引块标识；
值得注意的是，如果波束B1方向上同时需要为其他终端传输其他部分的***广播消息时，则该部分消息可以和上述更新的消息合并在一起传输，由终端根据索引块信息及自身需求决定取用哪部分***广播消息。
终端UE1接收被更新的***广播信息。
