Description

频带范围上报的方法和通信装置
本申请要求于2021年7月9日提交中国国家知识产权局、申请号为202110780071.8、申请名称为“频带范围上报的方法和通信装置”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本申请涉及通信领域，尤其涉及一种频带范围上报的方法通信装置。
背景技术
随着人们对通信需求的不断增长，第五代通信技术支持的工作带宽大幅增加，提供更大的通信容量和更高的通信速率。第三代合作伙伴计划(3rd generation partnership project，3GPP)协议定义第五代(5th generation，5G)系统可以支持100MHz(可以称为FR1频段)甚至400MHz(可以称为FR2频段)的工作带宽，另外，5G时代主流频谱是大带宽的时分双工(time division dual，TDD)频段，比如n78频段的协议频段范围是3300MHz～3800MHz，相较4G时代主流的FDD频段，频带范围明显增大，而终端由于性价比或者器件性能的限制，可能无法支持大带宽或者无法支持协议频段的全频带范围。
基于上述原因，5G网络与终端设备实际支持的频带范围存在多样性，可能出现终端支持的频带范围与网络的频带范围不对齐，从而导致终端无法入网或者接入后无法正常工作的问题。

一种技术中，在终端与网络频带不对齐的情况下，可以通过对终端支持的频带范围进行剪裁以实现终端的正常入网和使用，但是剪裁后的终端仅能在特定的网络下使用，造成终端能力的折损和带宽的浪费，而在本申请提出的技术方案中，不需要对终端能力进行剪裁，终端仅需要将自身能力上报，由网络设备根据终端支持的频带范围和第一小区的频带范围灵活地为终端设备配置合适的频带范围，以解决终端与网络频带不对齐所导致的无法入网或者无法使用的问题。该方案对于5G终端漫游的频带不对齐问题尤为重要，5G终端漫游时，通过使用该方案终端可以适应当地网络可能出现的频带范围多样性，即使频带范围不对齐，也能够正常入网和使用。

其中，可穿戴设备也可以称为穿戴式智能设备，是应用穿戴式技术对日常穿戴进行智能化设计、开发出可以穿戴的设备的总称，如眼镜、手套、手表、服饰及鞋等。可穿戴设备即直接穿在身上，或是整合到用户的衣服或配件的一种便携式设备。可穿戴设备不仅仅是一种硬件设备，更是通过软件支持以及数据交互、云端交互来实现强大的功能。广义穿戴式智能设备包括功能全、尺寸大、可不依赖智能手机实现完整或者部分的功能，例如：智能手表或智能眼镜等，以及只专注于某一类应用功能，需要和其它设备如智能手机配合使用，如各类进行体征监测的智能手环、智能首饰等。
此外，在本申请实施例中，终端设备还可以是物联网系统中的终端设备，IoT是未来信息技术发展的重要组成部分，其主要技术特点是将物品通过通信技术与网络连接，从而实现人机互连，物物互连的智能化网络。
此外，在本申请实施例中，终端设备还可以包括智能打印机、火车探测器、加油站等传感器，主要功能包括收集数据(部分终端设备)、接收网络设备的控制信息与下行数据，并发送电磁波，向网络设备传输上行数据。
本申请实施例中的网络设备可以是用于与终端设备通信的设备，该网络设备可以是全球移动通信(global system for mobile communications，GSM)系统或码分多址(code division multiple access，CDMA)中的基站(base transceiver station，BTS)，也可以是宽带码分多址(wideband code division multiple access，WCDMA)系统中的基站B(nodeB，NB)，还可以是LTE系统中的演进型基站B(evolved nodeB，eNB或eNodeB)，还可以是云无线接入网络(cloud radio access network，CRAN)场景下的无线控制器，还可以是无线网络控制器(radio network controller，RNC)、基站控制器(base station controller，BSC)、家庭基站(例如，home evolved nodeB，或home nodeB，HNB)、基带单元(baseband unit，BBU)，或者该网络设备可以为中继站、接入点、车载设备、可穿戴设备以及5G网络中 的网络设备或者未来演进的PLMN网络中的网络设备等，可以是WLAN中的接入点(access point，AP)、无线中继节点、无线回传节点、传输点(transmission point，TP)或者发送接收点(transmission and reception point，TRP)等,可以是新型无线系统(new radio，NR)系统中的gNB或传输点(TRP或TP)，或者，5G系统中的基站的一个或一组(包括多个天线面板)天线面板，或者，还可以为构成gNB或传输点的网络节点，如基带单元(BBU)，或，分布式单元(distributed unit，DU)等，本申请实施例并不限定。
在一些部署中，gNB可以包括集中式单元(centralized unit，CU)和DU。gNB还可以包括有源天线单元(active antenna unit，简称AAU)。CU实现gNB的部分功能，DU实现gNB的部分功能，比如，CU负责处理非实时协议和服务，实现无线资源控制(radio resource control，RRC)，分组数据汇聚层协议(packet data convergence protocol，PDCP)层的功能。DU负责处理物理层协议和实时服务，实现无线链路控制(radio link control，RLC)层、媒体接入控制(media access control，MAC)层和物理(physical，PHY)层的功能。AAU实现部分物理层处理功能、射频处理及有源天线的相关功能。由于RRC层的信息最终会变成PHY层的信息，或者，由PHY层的信息转变而来，因而，在这种架构下，高层信令，如RRC层信令，也可以认为是由DU发送的，或者，由DU+AAU发送的。可以理解的是，网络设备可以为包括CU节点、DU节点、AAU节点中一项或多项的设备。此外，可以将CU划分为接入网(radio access network，RAN)中的网络设备，也可以将CU划分为核心网(core network，CN)中的网络设备，本申请对此不做限定。

此外，在本申请实施例中，网络设备可以包括基站(gNB)，例如宏站、微基站、室内热点、以及中继节点等，功能是向终端设备发送无线电波，一方面实现下行数据传输，另一方面发送调度信息控制上行传输，并接收终端设备发送的无线电波，接收上行数据传输。
为便于理解本申请实施例，下面对本申请中涉及的几个术语做简单介绍。
(1)协议频段：协议划分的不同频段。表1中给出了几种5G的TDD协议频段的范围。
表1
Figure PCTCN2022103542-appb-000001
Figure PCTCN2022103542-appb-000002
(2)频带：包括一个或者多个频率点，该一个或者多个频率点可以是连续的，或者非连续的，例如，频带可以包括2515MHz～2615MHz之间的频率点。
(3)带宽：频带的宽度。例如：终端支持n41频段中2515MHz～2615MHz的频带，其中，带宽为100MHz。
(4)频带范围的起始频率点：指该频带范围内包含的最小频率点。为便于理解，这里举例进行说明，假设频带范围是2515MHz～2615MHz，则该频带范围的起始频率点为2515MHz。假设频带范围是4400MHz～5000MHz，则该频带范围的起始频率点为4400MHz。可以理解，起始频率点是相对于频带范围而言的，不同的频带范围的起始频率点可以不同。
(5)频带范围的结束频率点：指该频带范围内包含的最大频率点。为便于理解，这里举例进行说明，假设频带范围是2515MHz～2615MHz，则该频带范围的结束频率点为2615MHz。假设频带范围是4400MHz～5000MHz，则该频带范围的结束频率点为5000MHz。可以理解，结束频率点是相对于频带范围而言的，不同的频带范围的结束频率点可以不同。
参见图2，图2是本申请给出的终端支持的频带范围与网络的频带范围不对齐的示意图。如图2所示，假设网络的实际频带范围是2500MHz～2600MHz，频段号为n41，终端支持n41频段中的2515MHz～2615MHz的频带范围。如果终端设备在该网络下上报支持n41频段的100MHz带宽，由于基站默认终端设备支持全频带范围，因此，网络设备根据上报的100MHz带宽为终端设备配置的频带范围为2500MHz～2600MHz，这时，由于终端设备实际不支持该网络的前15MHz带宽，这时会因为终端支持的频带范围与网络的频带范围不对齐而导致终端设备入网异常或接入后无法正常工作的问题。
有鉴于此，本申请实施例提供了一种频带范围上报的方法，可以确保终端设备正常入网和使用。以下结合附图，对本申请实施例提供的方法进行介绍。
参见图3，图3是本申请提出的一种频带范围上报的方法的示意性交互图。
S301，终端设备驻留第一小区，其中，第一小区为网络设备服务的小区。
具体的，终端设备从网络设备发送的系统信息块(system information block，SIB)1消息中获取载波带宽和频带范围起始频率点两个参数，其中，载波带宽用于指示第一小区的带宽，频带范围起始频率点用于指示第一小区支持的频带范围的起始频率点，终端设备基于载波带宽和频带范围完成第一小区驻留。
需要说明的是，在此阶段终端设备可以不执行载波带宽和频带范围的校验，因此，虽然终端设备的实际频带范围与第一小区支持的频带范围不对齐，可以不影响终端设备发起后续的初始接入流程。
在一种实现方式中，为避免终端设备无法接入，协议支持网络设备为终端设备配置一个带宽较小的初始带宽部分(bandwidth part，BWP)，终端设备在该初始BWP上发起初 始接入过程，该初始BWP位于第一频带范围所在频段的中心或者其他合适位置。作为示例，终端设备从网络设备发送的SIB1消息中获取初始BWP信息，从而完成接入流程。
应理解，UE完成初始接入后，可以从RRC空闲状态进入到RRC连接(RRC Connection)状态。
需要说明是，S301为可选步骤。
S302，终端设备确定第一信息，第一信息用于指示第一频带范围，第一频带范围为终端设备支持的频带范围。
可选地，在S302之前，该方法还包括：网络设备向终端设备发送请求消息，该请求消息用于请求终端设备上报第一频带范围。
本实施例中，第一信息可以通过多种实施方式指示第一频带范围。
作为第一种可能的实施方式，第一信息可以包括第一频带范围的带宽大小的信息和用于确定第一频带范围的起始频率点的信息。可以理解，频带范围的起始频率点是指该频带范围对应的起始点。例如：第一频带范围为2536～2636MHz，则第一频带范围的起始频率点为2536MHz，第一频带范围的带宽大小为100MHz。用于确定第一频带范围的起始频率点的信息可以直接指示该第一频带范围的起始频率点，例如用于确定第一频点范围的起始频率点的信息包括2536MHz的信息，或者可以间接指示该第一频带范围的起始频率点，例如，用于确定第一频带范围的起始频率点的信息可以包括参数，根据该参数可以计算出第一频带范围的起始频率点。
作为第二种可能的实施方式，第一信息可以包含第一频带范围的起始频率点的信息和结束频率点的信息。作为示例，第一频带范围为2536～2636MHz，则可以第一信息包含起始频率点2536MHz和结束频率点2636MHz。
作为示例，下面给出几种可能的确定第一频带范围的方式，其中，方式一和方式三为上述第一种可能的实施方式的示例，方式二和方式四为上述第二种可能的实施方式的示例：
方式一：
第一信息包括第一频带范围的带宽大小的信息和用于确定第一频带范围的起始频率点的信息，方式一中主要介绍如何确定第一频带范围的起始频率点。第一频带范围的起始频率点的信息包括参数C，且第一频带范围的起始频率点A可以表示为：A＝B+C*D，其中，B为第一频带范围所在频段的一个频率点，D为带宽步长，D和C均为大于或等于0的数，B、D和C可以是整数或者不是整数，本申请实施例对此不作限定。
应理解，第一频带范围所在频段是指终端设备支持的频段范围所在的频段。例如：n41频段的频带范围为2496～2690MHz，但终端设备由于硬件规则限制等，仅支持n41频段中的一部分，例如：终端设备支持的频带范围为2536～2636MHz，那么在该示例中终端设备支持的频带范围所在的频段即代表n41频段。
在一种具体实现方式中，参数C可以是整数，可通过N个比特对应的取值表示，例如：N＝6，则C的取值范围为0至2 N-1，具体地，当C＝000010时，则表示C的取值为2。
可选的，B和D可以是预配置的。示例性地，可以是通过第三代合作伙伴计划(3rd generation partnership project，3GPP)协议预先定义，然后将参数B和D预先配置在网络设备和终端设备中。例如：预配置B为n41频段的起始频率点2496MHz，或者B为距离 该频段的起始频率点的最小的10倍的整数，即2500MHz。例如，D可定义为10MHz、20MHz或者30MHz等，D可以根据不同的频段确定，比如n41频段(2496MHz～2690MHz)采用20MHz步长，n77频段(3300MHz～4200MHz)采用30MHz步长，本申请对此不作限定。
可选的，B和D也可以携带在第一频带范围的起始频率点的信息中。
可选的，B和D中的一个参数可以是预配置的，另一个携带在第一频带范围的起始频率点的信息中。
需要说明的是，方式一中只是示例性的给出了第一频带范围的起始频率点A一种可能的计算规则。实际中，第一频带范围的起始频率点A的计算规则可以是预配置的，预配置在终端设备和网络设备，或者，也可以由终端设备和网络设备协商后进行统一配置，本申请对此不做限定。
为便于理解，对方式一举例说明：假设第一频带范围为2536MHz～2636MHz，C＝2，D＝20MHz，假设B为第一频带范围所在频段的起始频率点，由于第一频带范围2536MHz～2636MHz为频段n41(2496MHz～2690MHz)的子集，因此B为n41频段的起始频率点2496MHz，则第一频带范围的起始频率点A＝2496MHz+2*20MHz＝2536MHz，之后，根据第一信息中包括的第一频带范围的带宽大小(该举例中为100MHz)和第一频带范围的起始频率点即可确定第一频带的范围为2536～2636MHz。
方式二：
第一信息包含第一频带范围的起始频率点信息和结束频率点信息。该方式中可以采用N个比特(bit)的2进制数表征C1和C2，其中低X个bit的C1表示起始频率点，本申请为了描述方便，将起始频率点表示为Astart，Astart＝B+C1*D，高Y个bit的C2表示结束频率点，本申请为了描述方便，将结束频率点表示为Aend，Aend＝B+C2*D，其中，X与Y的和为N，X和Y均为大于或等于0的整数，其中，B可以表示第一频带范围所在频段的一个频率点，D可以表示带宽步长，具体可以参见方式一中的描述。
例如：N＝10，X＝Y＝5，也就是说，C1和C2各占5bit，5bit的C1和C2取值范围均为0至31(即2 5-1)，则当D＝30MHz时，C1*D(或C2*D)最大可以表示为31*30MHz，即930MHz，可以支持表1中带宽最大的n77频段(4200MHz-3300MHz＝900MHz)内的频率点。为便于理解，这里假设第一频带范围为4000MHz～4100MHz，B为n77的起始频率点3300MHz，如果C1*D支持的最大范围过小，比如C1*D最大只能取到为500MHz，那么该示例中Astart＝B+C1*D最大只能取到Astart＝3300MHz+500MHz＝3800MHz，无法表示该示例中第一频带范围的起始频率点4000MHz，C2*D取值过小同理。因此，实际中在使用方式二时可以根据第一频带范围对应的具体范围灵活的决定C1、C2所占的bit个数以及D的大小。
为便于理解，对方式二举例说明：N＝10，X＝Y＝5时，低5bit的C1为00010，即C1取值为2，而高5bit的C2为00111，即C2取值为7。假设第一频带范围为2536～2636MHz，C1＝2，C2＝7，D＝20MHz，B为第一频带范围所在频段的起始频率点，由于第一频带范围2536～2636MHz为频段n41(2496MHz～2690MHz)的子集，因此B为n41频段的起始频率点2496MHz，则第一频带范围的起始频率点Astart＝2496MHz+2*20MHz＝2536MHz，而结束频率点Aend＝2496MHz+7*20MHz＝2536MHz。
方式三：
第一信息包括第一频带范围的带宽大小的信息和用于确定第一频带范围的起始频率点的信息。该方式中第一频带范围可采用资源指示值(resource indicator value，RIV)的方式，即指示终端设备支持的频带范围的起始频率点和带宽长度。具体示例，第一频带范围的起始频率点A＝B+C，其中，B为第一频带范围所在频段的起始频率点，C表示第一频带范围的起始频率点A距离B的长度，C可以使用一个N位的bit(例如：10bit)的二进制数表示。例如，第一频带范围所在频段为频段n41(2496MHz～2690MHz)，则B可以为2496MHz。又例如，第一频带范围所在频段为频段n77(3300MHz～4200MHz)，则B为3300MHz。带宽长度Len则表示距离第一频带范围的起始频率点A的长度，使用一个Mbit(例如：10bit)二进制数表示，其中，M和N可以相等，也可以不相等。
为便于理解，对方式三举例说明：频段n41中第一频带范围是2536～2636MHz，则B为n41频段的起始频率点2496MHz，C采用一个10bit二进制数101000时，即表示十进制的40，则第一频带范围的起始频率点A＝2496MHz+40MHz＝2536MHz；带宽长度Len也采用一个10bit二进制数1100100时，即表示十进制的100，则带宽长度为100MHz，因此第一频带范围为2536MHz～2636MHz。
方式四：
第一信息包含第一频带范围的起始频率点信息和结束频率点信息。该方式可由终端上报直接两个数值实现，即起始频率点和结束频率点，其中两个频率点分别用二进制数表示，上报占用的比特数可以根据实际情况确定，本申请不作具体限定。例如：n79频段范围为4400MHz～5000MHz，起始频率点4400和结束频率点5000可由两个13bit的2进制数表示。
为便于理解，对方式四举例说明：第一频带范围为2536MHz～2636MHz，则第一频带范围的起始频率点Astart用100111101000表示，即十进制的2536MHz，而第一频带范围的结束频率点Astart用101001001100表示，即十进制的2636MHz。
S303，终端设备向网络设备发送第一信息。
对应的，网络设备接收终端设备发送的第一信息，并根据第一信息确定终端设备支持的频带范围。
在一种具体的实现方式中，终端设备可以通过UE能力上报信令(即第一信息的一例)中的上报第一频带范围的带宽大小和第一频带范围的起始频率点。
一种技术中，在终端与网络频带不对齐的情况下，可以通过对终端支持的频带范围进行剪裁以实现终端的正常入网和使用，但是剪裁后的终端仅能在特定的网络下使用，造成终端能力的折损和带宽的浪费。而在本申请提出的技术方案中，不需要对终端能力进行剪裁，终端仅需要将自身能力上报，网络设备可以根据终端支持的频带范围和网络设备的频带范围灵活地为终端设备配置合适的频带范围，以解决终端与网络频带不对齐所导致的无法入网或者无法使用的问题。该方案对于5G终端漫游的频带不对齐问题尤为重要，5G终端漫游时，通过使用该方案终端可以适应当地网络可能出现的频带范围多样性，即使频带范围不对齐，也能够正常入网和使用。
示例的，下面结合S304～S306给出一种网络设备确定终端设备支持的合适的频带范围合适的频带范围的方法。
S304，网络设备根据第一信息确定第一配置信息，第一配置信息包括第三频带范围。其中，第三频带范围为第一频带范围和第二频带范围的交集的部分或全部，第二频带范围为第一小区支持的频带范围。
S305，网络设备向终端设备发送第一配置信息。
对应的，终端设备从网络设备接收第一配置信息。
在一种具体的实现方式中，网络设备通过RRC重配置消息为终端设备配置BWP(即第三频带范围)。
可选的，网络设备最多可以为终端设备配置4个不同的BWP(即配置4个不同的第三频带范围)。
S306，终端设备和网络设备在第三频带范围进行通信。
可以看出，上述方法中网络设备通过获取终端和第一小区所支持的频带范围的交集确定合适的BWP，以解决终端无法入网或者无法使用的问题。其中，第三频带范围可以配置为终端设备支持的频带范围和网络频带范围交集的最大带宽，从而可以充分发挥5G的大带宽优势。
