Description

Method and device for status notification

Technical field

本发明涉及通信技术领域，特别涉及一种状态通知的方法及装置。The present invention relates to the field of communications technologies, and in particular, to a method and apparatus for status notification.

Background technique

授权频谱辅助接入(License Assisted Access，LAA)指在非授权频谱使用长期演进(Long Term Evolution，LTE)的技术。目前，在非授权频谱上使用的主要技术是无线保真(Wireless Fidelity，WIFI)，LTE系统可以利用非授权频谱作为LTE基站的辅小区(Scell)频谱资源使用。授权频谱辅助接入在占用信道资源时，小区处于cell on，即小区开状态(小区正常发射功率)；在出让信道资源时，小区处于cell off，即小区关状态(小区关闭功率发射，不发送小区级参考信号(Cell-specific Reference Signal，CRS))。为了使得LTE系统/WIFI系统友好共存，授权频谱辅助接入根据一定的规则周期性的判决出让非授权频谱资源的比例，动态调整每个系统的工作时间，因此需要更新cell on/off的周期和/或比例，以实现LTE系统与WIFI系统在非授权频段的友好共存。Licensed Assisted Access (LAA) refers to the technology of using Long Term Evolution (LTE) in unlicensed spectrum. At present, the main technology used on the unlicensed spectrum is Wireless Fidelity (WIFI), and the LTE system can utilize the unlicensed spectrum as the secondary cell (Scell) spectrum resource of the LTE base station. Authorized spectrum-assisted access When the channel resources are occupied, the cell is in cell on, that is, the cell is in the state (the cell normal transmission power); when the channel resource is transferred, the cell is in the cell off state, that is, the cell is off state (the cell is off the power transmission, not transmitting) Cell-specific Reference Signal (CRS)). In order to make the LTE system/WIFI system friendly coexistence, the licensed spectrum assisted access periodically decides the proportion of unlicensed spectrum resources according to a certain rule, dynamically adjusts the working time of each system, and therefore needs to update the cell on/off period and / or ratio to achieve friendly coexistence of LTE systems and WIFI systems in unlicensed bands.

为了保证用户设备(User Equipment，UE)与基站能同步cell on/off状态，目前是采用介质访问控制控制单元(MAC(Media Access Control，介质访问控制)Control Element，MCE)激活/去激活的方式，在on/off状态转换之前，基站提前调度，发送MCE通知UE激活/去激活，以通知UE该基站进入了cell on状态/cell off状态。In order to ensure that the user equipment (User Equipment, UE) and the base station can synchronize the cell on/off state, the medium access control control unit (MAC (Media Access Control) Control Element, MCE) is activated/deactivated. Before the on/off state transition, the base station schedules in advance, and sends an MCE to notify the UE to activate/deactivate to notify the UE that the base station enters the cell on state/cell off state.

发明人发现现有技术至少存在以下问题：The inventors have found that the prior art has at least the following problems:

基站在每次进行cell on/off状态转换时，都需要向UE发送MCE激活/去激活消息。如此频繁的MCE消息的发送，会造成空口资源的极大浪费。The base station needs to send an MCE activation/deactivation message to the UE each time the cell on/off state transition is performed. The sending of such frequent MCE messages will result in a huge waste of air interface resources.

detailed description

为使本发明的目的、技术方案和优点更加清楚，下面将结合附图对本发明实施方式作进一步地详细描述。The embodiments of the present invention will be further described in detail below with reference to the accompanying drawings.

实施例1Example 1

本发明实施例提供了一种状态通知的方法，参见图1。该方法包括：An embodiment of the present invention provides a method for status notification, as shown in FIG. 1. The method includes:

101：基站确定小区开关状态信息是否需要调整，小区开关状态信息至少包括以下一种：小区开关状态的周期以及小区开关状态的比例；101: The base station determines whether the cell switch state information needs to be adjusted, and the cell switch state information includes at least one of the following: a period of the cell switch state and a proportion of the cell switch state;

102：如果确定小区开关状态信息需要调整，则获取调整后的小区开关状态信息；102: If it is determined that the cell switch state information needs to be adjusted, obtaining the adjusted cell switch state information;

103：将调整后的小区开关状态信息发送给UE用于UE根据调整后的小区开关状态信息获取非授权频谱资源。103: Send the adjusted cell switch state information to the UE, where the UE acquires the unlicensed spectrum resource according to the adjusted cell switch state information.

其中，在基站中存在有两个小区，一个为授权频谱辅助接入主小区，另一个为授权频谱辅助接入辅小区。本发明实施例中基站会周期性的执行确定小区开关状态信息是否需要调整的步骤。There are two cells in the base station, one is for the licensed spectrum to access the primary cell, and the other is for the licensed spectrum to access the secondary cell. In the embodiment of the present invention, the base station periodically performs a step of determining whether the cell switch state information needs to be adjusted.

其中，确定小区开关状态信息是否需要调整以及获取调整后的小区开关状态信息的步骤由授权频谱辅助接入辅小区执行，授权频谱辅助接入辅小区在获取到调整后的小区开关状态信息之后，通知授权频谱辅助接入主小区执行更新小区开关状态信息的操作，即由授权频谱辅助接入主小区将调整后的小区开关状态信息发送给UE。The step of determining whether the cell switch state information needs to be adjusted and obtaining the adjusted cell switch state information is performed by the authorized spectrum auxiliary access secondary cell, and after the licensed spectrum auxiliary access secondary cell obtains the adjusted cell switch state information, Notifying the authorized spectrum to access the primary cell to perform the update The operation of the cell switch state information, that is, the authorized spectrum auxiliary access primary cell sends the adjusted cell switch state information to the UE.

其中，授权频谱辅助接入辅小区在确定了调整后的小区开关状态信息后，一方面需要通知UE更新UE自身存储的小区开关状态信息，另一方面也要更新授权频谱辅助接入辅小区自身存储的小区开关状态信息，以便授权频谱辅助接入辅小区按照调整后的小区开关状态信息进行后续的操作。After the determined spectrum auxiliary access secondary cell determines the adjusted cell switch state information, the UE needs to notify the UE to update the cell switch state information stored by the UE itself, and also needs to update the licensed spectrum to assist the access secondary cell itself. The stored cell switch state information is used to authorize the spectrum auxiliary access secondary cell to perform subsequent operations according to the adjusted cell switch state information.

例如：小区开/关状态的总的周期为200ms；小区开状态的周期和小区关状态的周期对应的比值为9:1。则说明小区开状态的周期为180ms，小区关状态的周期为20ms。For example, the total period of the cell on/off state is 200 ms; the ratio of the period of the cell on state to the period of the cell off state is 9:1. The period of the cell open state is 180 ms, and the period of the cell off state is 20 ms.

本发明实施例通过在判决出需要调整小区开关状态信息后，将调整后的小区开关状态信息发送给UE，以使UE根据调整后的小区开关状态信息获取非授权频谱资源。基站无需在每次小区开/关状态变更时通知UE，实现了UE自动根据调整后的小区开关状态信息进行相应的操作调整，提高了空口资源的利用率。After determining that the cell switch state information needs to be adjusted, the embodiment of the present invention sends the adjusted cell switch state information to the UE, so that the UE acquires the unlicensed spectrum resource according to the adjusted cell switch state information. The base station does not need to notify the UE every time the cell on/off state is changed, and the UE automatically performs corresponding operation adjustment according to the adjusted cell switch state information, thereby improving the utilization of the air interface resource.

实施例2Example 2

本发明实施例提供了一种状态通知的方法，参见图2。该方法包括：The embodiment of the invention provides a method for status notification, see FIG. 2 . The method includes:

201：终端接收基站发送的调整后的小区开关状态信息，小区开关状态信息至少包括以下一种：小区开关状态的周期以及小区开关状态的比例；201: The terminal receives the adjusted cell switch state information sent by the base station, where the cell switch state information includes at least one of the following: a period of the cell switch state and a proportion of the cell switch state.

202：根据调整后的小区开关状态信息，获取非授权频谱资源。202: Acquire an unlicensed spectrum resource according to the adjusted cell switch state information.

本发明实施例通过接收基站在调整了小区开关状态信息后向UE发送的调整后的小区开关状态信息，并根据该小区开关状态信息获取非授权频谱资源。基站无需在每次小区开/关状态变更时通知UE，实现了UE自动根据调整后的小区开关状态信息进行相应的操作调整，提高了空口资源的利用率。The embodiment of the present invention receives the adjusted cell switch state information that is sent by the base station to the UE after adjusting the cell switch state information, and obtains the unlicensed spectrum resource according to the cell switch state information. The base station does not need to notify the UE every time the cell on/off state is changed, and the UE automatically performs corresponding operation adjustment according to the adjusted cell switch state information, thereby improving the utilization of the air interface resource.

实施例3Example 3

本发明实施例提供了一种状态通知的方法，参见图3。该方法包括：The embodiment of the invention provides a method for status notification, see FIG. 3. The method includes:

301：基站确定小区开关状态信息是否需要调整，小区开关状态信息至少包括以下一种：小区开关状态的周期以及小区开关状态的比例。301: The base station determines whether the cell switch state information needs to be adjusted, and the cell switch state information includes at least one of the following: a period of the cell switch state and a proportion of the cell switch state.

其中，本步骤是由基站中的授权频谱辅助接入辅小区进行的操作，该操作过程可以由以下步骤进行实现： The step is an operation performed by the authorized spectrum in the base station to access the secondary cell, and the operation process can be implemented by the following steps:

3011：周期性的检测非授权频谱上业务负载状态和/或自身的业务量。3011: Periodically detecting the traffic load status and/or its own traffic on the unlicensed spectrum.

其中，可以仅侦测非授权频谱上业务负载状态；也可以仅检测自身的业务量；还可以通过侦测非授权频谱上业务负载状态和自身的业务量共同进行检测。The service load status on the unlicensed spectrum may be detected only; or the traffic volume of the unlicensed spectrum may be detected; and the service load status on the unlicensed spectrum and the traffic volume on the unlicensed spectrum may be detected together.

其中侦听检测，可以是通过能量测量，也可以是通过信号解析或者通过UE进行辅助测量，也可以通过其他方式，在此并不限定。The interception detection may be performed by energy measurement, or by signal analysis or by the UE for auxiliary measurement, or by other means, which is not limited herein.

3012：根据非授权频谱上业务负载状态和/或自身的业务量，确定是否需要调整小区开关状态信息。3012: Determine, according to the service load status on the unlicensed spectrum and/or the traffic volume of the self, whether to adjust the cell switch state information.

其中，调整原则为：当非授权频谱上业务负载变重时，会结合基站自身业务情况，适当出让非授权频谱资源，将小区开状态的周期调短，小区关状态的周期调长，以保证WIFI对非授权频谱资源的占用，达到LTE与WIFI友好共存的目的；反之，当基站侦听到非授权频谱上业务负载变轻时，基站也会结合自身的业务量，适当的多占用非授权频谱资源，缩短小区关状态的周期，增加小区开状态的周期，以保证合理利用非授权频谱资源。The adjustment principle is as follows: when the service load on the unlicensed spectrum becomes heavy, the unlicensed spectrum resources are appropriately transferred in combination with the service status of the base station, and the period of the cell open state is shortened, and the period of the cell off state is lengthened to ensure The occupation of unlicensed spectrum resources by WIFI achieves the purpose of LTE and WIFI friendly coexistence; on the contrary, when the base station detects that the service load on the unlicensed spectrum becomes light, the base station also combines its own traffic volume and appropriately occupies non-authorization. The spectrum resource shortens the period of the cell off state and increases the period of the cell open state to ensure reasonable utilization of unlicensed spectrum resources.

其中，该新增字段内容如下：Among them, the content of the new field is as follows:

上述内容中可以携带UE端需要获知的内容如下：The content that needs to be learned by the UE at the above content is as follows:

(1)小区开/关状态的周期：考虑授权频谱辅助接入系统如果长时间占用非授权频谱，会导致WIFI的beacon无法发送，进而使WIFI的终端掉线或无法接入，因此，小区开/关状态的周期可以考虑在200ms以内(考虑到授权频谱辅助接入与WIFI的公平性，小区开/关状态的最短时长都定义为10ms)。可以使用表1中定义的方式传输小区开/关状态周期。(1) Period of the cell on/off state: Considering that the licensed spectrum auxiliary access system occupies the unlicensed spectrum for a long time, the Wacon beacon cannot be sent, and the WIFI terminal is disconnected or cannot be accessed. Therefore, the cell is opened. The period of the /off state can be considered within 200 ms (taking into account the fairness of the licensed spectrum assisted access and WIFI, the shortest duration of the cell on/off state is defined as 10 ms). The cell on/off status period can be transmitted using the manner defined in Table 1.

表1Table 1

其中，p0表示Pattern Id为0，代表小区开/关状态的周期为100ms；p1表示Pattern Id为1，代表小区开/关状态的周期为200ms。Wherein, p0 indicates that the Pattern Id is 0, and the period of the cell on/off state is 100 ms; p1 indicates that the Pattern Id is 1, and the period of the cell on/off state is 200 ms.

(2)小区开/关状态转换的时刻：基站配置小区开/关状态的pattern id，onoffOffset，UE在帧号和子帧号满足如下条件时进入小区开/关状态转换：(2) Time of cell on/off state transition: The base station configures the pattern id of the cell on/off state, onoffOffset, and the UE enters the cell on/off state transition when the frame number and the subframe number satisfy the following conditions:

SFN mod T＝FLOOR(onoffOffset/10)；SFN mod T=FLOOR(onoffOffset/10);

subframe＝onoffOffset mod 10；with T＝P/10；Subframe=onoffOffset mod 10;with T=P/10;

其中：P为On/Off Repetition Period；onoffOffset在pattern id为0时的范围是10～89，在pattern id为1时的范围是10～189。Where: P is the On/Off Repetition Period; onoffOffset is in the range of 10 to 89 when the pattern id is 0, and 10 to 189 when the pattern id is 1.

(3)小区索引或小区的物理小区ID。(3) Cell index or physical cell ID of the cell.

基站在非授权频谱上，确定需要更新调整后的小区开关状态信息后，可以通过授权频谱辅助接入主小区的无线资源控制(Radio Resource Control，RRC)重配置消息，携带调整后的小区开关状态信息，通知该非授权频谱下的所有处于连接态的UE，以保证UE与基站的非授权频谱的小区开/关状态保持同步。After determining, on the unlicensed spectrum, the base station needs to update the adjusted cell switch state information, the base station may perform the radio resource control (RRC) reconfiguration message of the primary cell by using the licensed spectrum to carry the adjusted cell switch state. The information is sent to all UEs in the unconnected spectrum to ensure that the UE is in synchronization with the cell on/off state of the unlicensed spectrum of the base station.

可选的，本公开实施例中在RRC重配置消息中的SCellToAddMod-r10中新增字段中的内容为示例性描述，还可以以其他形式示出，在此并不限定新增字段中的内容。Optionally, the content in the newly added field in the SCellToAddMod-r10 in the RRC reconfiguration message in the embodiment of the disclosure is an exemplary description, and may also be shown in other forms, and the content in the newly added field is not limited herein. .

需要说明的是，UE与基站在非授权频谱上的小区开/关状态同时生效。It should be noted that the cell on/off state of the UE and the base station on the unlicensed spectrum is valid at the same time.

304：接收基站发送的无线资源控制RRC重配置消息，RRC重配置消息中包括调整后的小区开关状态信息。304: Receive a radio resource control RRC reconfiguration message sent by the base station, in an RRC reconfiguration message. The adjusted cell switch status information is included.

305：根据调整后的小区开关状态信息，获取非授权频谱资源。305. Acquire an unlicensed spectrum resource according to the adjusted cell switch state information.

UE获取到了调整后的小区开关状态信息，并将该调整后的小区开关状态信息更新自身存储的小区开关状态信息。更新之后会按照新的小区开关状态信息生效。The UE obtains the adjusted cell switch state information, and updates the adjusted cell switch state information to the cell switch state information stored by itself. After the update, it will take effect according to the new cell switch status information.

即UE会根据自身存储的小区开关状态信息，确定小区在什么时间进入小区开/关状态，因此UE在确定小区进入小区关状态时不进行CRS检测、参考信号接收功率(Reference Signal Receiving Power，RSRP)、参考信号接收质量(Reference Signal Receiving Quality，RSRQ)测量等操作，即获取到非授权频谱资源。That is, the UE determines the time when the cell enters the cell on/off state according to the cell switch state information stored by the UE. Therefore, the UE does not perform CRS detection and reference signal receiving power (Reference Signal Receiving Power, RSRP) when determining that the cell enters the cell off state. ), reference signal reception quality (RSRQ) measurement and other operations, that is, acquisition of unlicensed spectrum resources.
