Description

频带修改方法、装置、终端及基站Band modification method, device, terminal and base station 技术领域Technical field
本发明涉及通信领域,具体而言,涉及一种频带修改方法、装置、终端及基站。The present invention relates to the field of communications, and in particular to a frequency band modification method, apparatus, terminal, and base station.
背景技术Background technique
长期演进(Long Term Evolution,简称为LTE)系统中,小区的中心工作载频通过EARFCN(E-UTRA Absolute Radio Frequency Channel Number)来标识,小区的EARFCN包含了小区的工作物理频率和工作频带的信息,以下用EARFCN(工作物理频率,工作频带)来标识该小区的工作载频。当前小区只支持一个频带,但由于运营商引入新的频带,在物理频率上跟已经存在的频带有重合,从而引出一种新的场景,即小区支持多频带,如图1所示,图1是相关技术中的多频带小区的结构示意图。为了前向兼容性,对于多频带的小区,基站会将旧的频带通过原有的信元通知终端,新增加的频带通过新的信元通知终端,这样原来的终端不会因为引入新频带而受到影响,新的支持多频带的终端可以认知新的信元,从而可以支持多频带的小区。对于小区的频带信息(包含原有的信元和新增的信元),基站是通过系统消息中的系统消息块1通知终端的,系统消息可以通过广播信道通知给终端,也可以通过专用消息如无线资源控制(Radio Resource Control,简称为RRC)消息通知给终端,终端在连接态下接收变化的系统消息时,对于频带信息的更新,是忽略的。In the Long Term Evolution (LTE) system, the central working carrier frequency of the cell is identified by the E-UTRA Absolute Radio Frequency Channel Number (EARFCN), and the EARFCN of the cell contains information about the working physical frequency and the working frequency band of the cell. The following uses EARFCN (working physical frequency, working frequency band) to identify the working carrier frequency of the cell. The current cell supports only one frequency band, but because the operator introduces a new frequency band, it overlaps with the existing frequency band on the physical frequency, thereby eliciting a new scenario, that is, the cell supports multiple frequency bands, as shown in FIG. It is a schematic structural diagram of a multi-band cell in the related art. For forward compatibility, for a multi-band cell, the base station notifies the terminal through the original cell, and the newly added frequency band notifies the terminal through the new cell, so that the original terminal does not introduce a new frequency band. Affected, new multi-band-capable terminals can recognize new cells and thus support multi-band cells. For the frequency band information of the cell (including the original cell and the newly added cell), the base station notifies the terminal through the system message block 1 in the system message, and the system message can be notified to the terminal through the broadcast channel, or through the dedicated message. For example, the radio resource control (Radio Resource Control, RRC for short) message is notified to the terminal, and when the terminal receives the changed system message in the connected state, the update of the band information is ignored.
为向移动用户提供更高的数据速率,高级长期演进系统(Long Term Evolution Advance,简称LTE-A)提出了载波聚合技术(Carrier Aggregation,简称CA),其目的是为具有相应能力的UE提供更大宽带,提高UE的峰值速率。LTE中,系统支持的最大下行传输带宽为20MHz,载波聚合是将两个或者更多的分量载波(Component Carriers,简称CC)聚合起来支持大于20MHz,最大不超过100MHz的传输带宽。具有载波聚合能力的LTE-A UE,可以同时在多个分量载波上收发数据。进行载波聚合的分量载波归属同一个频带称为同频带载波聚合,归属不同的频带称为异频带载波聚合。LTE-A系统中,终端进入连接态后可以同时通过多个分量载波(如CC1,CC2)与源基站进行通信,基站会通过显式的配置或者按照协议约定为UE指定一个主分量载波(Primary Component Carrier,简称为PCC),其他的分量载波称为辅分量载波(Secondary Component Carrier,简称为SCC),在下行主载波单元(Downlink Primary Component Carrier,简称为DL PCC)上的服务小区称为主服务小区(Primary Cell,简称为Pcell),在下行辅载波单元(Downlink Secondary Component Carrier,简称为DL  SCC)上的服务小区称为辅服务小区(Secondary Cell,简称为Scell)。但是在相关技术中,对于多频带小区如何进行载波聚合,尚未有公开的技术。In order to provide mobile users with higher data rates, the Long Term Evolution Advance (LTE-A) proposes Carrier Aggregation (CA), which aims to provide more UEs with corresponding capabilities. Large broadband, increasing the peak rate of the UE. In LTE, the maximum downlink transmission bandwidth supported by the system is 20 MHz. Carrier aggregation is to aggregate two or more component carriers (CC) to support a transmission bandwidth greater than 20 MHz and a maximum of 100 MHz. An LTE-A UE with carrier aggregation capability can transmit and receive data on multiple component carriers simultaneously. The component carriers that perform carrier aggregation belong to the same frequency band, which is called the same-band carrier aggregation, and the different frequency bands are called hetero-band carrier aggregation. In the LTE-A system, after the terminal enters the connected state, it can communicate with the source base station through multiple component carriers (such as CC1 and CC2) at the same time. The base station specifies a primary component carrier (Primary) by explicit configuration or according to the protocol. The component carrier (referred to as PCC), the other component carrier is called the secondary component carrier (SCC), and the serving cell on the downlink primary component carrier (DL PCC) is called the master. Primary Cell (Pcell), Downlink Secondary Component Carrier (DL) The serving cell on the SCC is called a secondary cell (Scell). However, in the related art, there is no disclosed technology for how to perform carrier aggregation for a multi-band cell.
针对相关技术中存在的无法实现多频带小区的载波聚合的问题,目前尚未提出有效的解决方案。For the problem of carrier aggregation that cannot implement multi-band cells in the related art, an effective solution has not been proposed yet.

下面结合具体的实施例对本发明进行说明。The invention will now be described in connection with specific embodiments.
例如,目前LTE时分双工(Time Division Duplexing,简称为TDD网络中使用了频带38和频带41,其中,小区1是归属频带38的,小区2是归属频带38和频带41的,小区3是归属频带41的,其中小区2是多频带小区。如表1所示:For example, in the current LTE time division duplexing (Time Division Duplexing, referred to as TDD network, the frequency band 38 and the frequency band 41 are used, wherein the cell 1 is the home frequency band 38, the cell 2 is the home frequency band 38 and the frequency band 41, and the cell 3 is the home. In band 41, cell 2 is a multi-band cell. As shown in Table 1:
表1Table 1
  是否归属频带38Whether to belong to the frequency band 38 是否归属频带41Whether to belong to the frequency band 41
小区1Community 1 Yes no
小区2 Community 2 Yes Yes
小区3Community 3 no Yes
假设,终端也存在多种,可以分类如表2所示:Assume that there are also a variety of terminals, which can be classified as shown in Table 2:
表2Table 2
  是否支持频带38Whether to support frequency band 38 是否支持频带41Whether to support band 41 是否支持多频带Whether to support multiple bands
终端1Terminal 1 Yes no no
终端2 Terminal 2 Yes Yes Yes
终端3Terminal 3 Yes Yes no
对于终端1,和终端2,3,都将以频带38接入小区2。终端2支持频带41的同频带载波聚合,不支持频带38和频带41的异频带载波聚合,并且在归属频带38的小区2进入连接态,基站计划将小区3配置给终端进行载波聚合,按照现有技术最简单的方法就是基站直接在RRC重配置中直接添加归属于频带41的小区3,由于终端1并不支持频带38和频带41的异频带载波聚合,终端将会执行RRC重建,引起业务中断。For terminal 1, and terminals 2, 3, both will access cell 2 in frequency band 38. The terminal 2 supports the same-band carrier aggregation of the frequency band 41, does not support the inter-band carrier aggregation of the frequency band 38 and the frequency band 41, and the cell 2 in the home frequency band 38 enters the connected state, and the base station plans to configure the cell 3 to the terminal for carrier aggregation. The simplest method is that the base station directly adds the cell 3 belonging to the frequency band 41 directly in the RRC reconfiguration. Since the terminal 1 does not support the inter-band carrier aggregation of the frequency band 38 and the frequency band 41, the terminal will perform RRC reconstruction to cause a service. Interrupted.
为了解决问题,在本发明实施例中,基站在添加小区3作为Scell时或添加小区3作为Scell前改变终端在小区2归属的频带。可以有以下几种办法:In order to solve the problem, in the embodiment of the present invention, the base station changes the frequency band to which the terminal belongs in the cell 2 when adding the cell 3 as the Scell or adding the cell 3 as the Scell. There are several ways to do this:
方法一:通过在RRC重配置操作中携带专用SIB1实现,并立即生效。Method 1: Implemented by carrying a dedicated SIB1 in the RRC reconfiguration operation, and takes effect immediately.
方法二:执行重配过程将终端在小区2中使用的频带改为41。 Method 2: Perform a reconfiguration process to change the frequency band used by the terminal in the cell 2 to 41.
采用本发明实施例中提出的方法,可以顺利完成终端进行多频带小区的载波聚合,而不引起业务中断。With the method proposed in the embodiment of the present invention, the terminal can perform carrier aggregation of the multi-band cell without causing service interruption.
下面结合表1和表2对上述实施例进行说明,假设场景如图11所示,该图11是根据本发明实施例的场景示意图。小区2和小区3都归属基站1,其中小区2归属频带38和41,小区3归属频带41。终端2支持频带38和41,同时支持多频带。为了前向兼容,基站1对于小区2的系统消息广播,将旧的频带此时为38通过原有的信元通知终端,新增加的频带此时为41通过新的信元通知终端。The foregoing embodiment is described below with reference to Table 1 and Table 2. It is assumed that the scenario is as shown in FIG. 11, which is a schematic diagram of a scenario according to an embodiment of the present invention. Both cell 2 and cell 3 belong to base station 1, where cell 2 is home to bands 38 and 41 and cell 3 is home to band 41. Terminal 2 supports bands 38 and 41 while supporting multiple bands. For forward compatibility, the base station 1 broadcasts the system message to the cell 2, and the old frequency band is now 38 to notify the terminal through the original cell, and the newly added frequency band is 41 to notify the terminal through the new cell.
