Description

一种天线控制方法、装置及终端设备An antenna control method, device and terminal equipment 技术领域technical field
本发明涉及通信技术领域，尤其涉及一种天线控制方法、装置及终端设备。The present invention relates to the field of communication technologies, and in particular, to an antenna control method, device and terminal device.
背景技术Background technique
长期演进(Long Term Evolution，LTE)系统能够为用户提供更加丰富的通信业务，但用户在享用这些通信业务时，终端设备的功耗问题也尤为重要。由于基于包的数据流通常是突发性的，在一段时间内有数据传输，但在接下来的一段较长时间内没有数据传输。The Long Term Evolution (Long Term Evolution, LTE) system can provide users with more abundant communication services, but when users enjoy these communication services, the power consumption of terminal equipment is also particularly important. Since packet-based data streams are usually bursty, there is data transmission for a period of time, but no data transmission for a longer period of time next.
目前，在没有数据传输的时间段内，可以通过停止监听物理下行控制信道(Physical Downlink Control Channel，PDCCH)来降低终端设备的功耗。针对这一特性，在LTE系统中提出无线资源控制连接(Radio Resource Control_CONNECTED，RRC_CONNECTED)状态下的非连续接收(Discontinuous Reception，DRX)机制，即RRC_CONNECTED状态下的DRX机制(也可以称为CDRX机制)。在该机制下，为处于RRC连接状态的终端设备配置一个DRX周期，也可以称为CDRX周期。如图1所示，为CDRX周期示意图，CDRX周期(图中00表示一个CDRX周期)由CDRX激活期(On Duration，图中01所示)和CDRX休眠期(Opportunity for DRX，图中02所示)组成：在CDRX激活期内，终端设备监听并接收PDCCH(激活态)；在CDRX休眠期内，终端设备不监听PDCCH以减少功耗(休眠态)。At present, in a period of time when there is no data transmission, the power consumption of the terminal device can be reduced by stopping monitoring the Physical Downlink Control Channel (PDCCH). In response to this feature, a discontinuous reception (DRX) mechanism in the radio resource control connection (Radio Resource Control_CONNECTED, RRC_CONNECTED) state is proposed in the LTE system, that is, the DRX mechanism in the RRC_CONNECTED state (also known as the CDRX mechanism) . Under this mechanism, a DRX cycle, which may also be called a CDRX cycle, is configured for a terminal device in an RRC connection state. As shown in Figure 1, it is a schematic diagram of the CDRX cycle. The CDRX cycle (00 in the figure represents a CDRX cycle) consists of a CDRX activation period (On Duration, shown in Figure 01) and a CDRX sleep period (Opportunity for DRX, shown in Figure 02). ) composition: during the CDRX activation period, the terminal device monitors and receives the PDCCH (active state); during the CDRX sleep period, the terminal device does not monitor the PDCCH to reduce power consumption (sleep state).
终端设备虽然在CDRX休眠期内，通过不监听PDCCH可以减少功耗，但是终端设备整体功耗仍然很大，如何进一步降低功耗是本领域技术人员不停研究的课题。Although the power consumption of the terminal equipment can be reduced by not monitoring the PDCCH during the CDRX sleep period, the overall power consumption of the terminal equipment is still very large, and how to further reduce the power consumption is the subject of constant research by those skilled in the art.

请参阅图3，为本发明实施例公开的CDRX周期示意图；其中，一个CDRX周期由激活期(On Duration)和休眠期(Opportunity for DRX)组成，在激活期内，终端设备监听并接收PDCCH；在休眠期内，终端设备不接收PDCCH，以减少功耗，但是可以接收来自其它物理信道的数据，如下行共享物理信道(Physical Downlink Share Channel，PDSCH)、ACK/NACK等。从时域上看，时间被划分成一个个连续的CDRX周期(CDRX Cycle)，CDRX周期的选择需要考虑电池节约与延迟之间的平衡，从一个方面讲，长CDRX周期有益于延长终端设备的电池使用时间，例如，网页浏览过程中，当用户正在阅读已经下载好的网页时，终端设备持续接收下行数据是对资源的浪费；从另一个方面讲，当有新的数据传输时，一个更短的CDRX周期有益于更快的响应，例如，用户请求另一个网页或者进行VoIP通话时。为了满足终端设备的上述需求，每个终端设备可以配置两个CDRX周期：短CDRX周期(shortRCX-Cycle)和长CDRX周期(longDRX-Cycle)。如果终端设备配置了短CDRX周期，则长CDRX周期应该配置为短CDRX周期的倍数。但在任一时刻，终端设备只能使用其中一种配置。图3中，10表示一个短CDRX周期，11表示该短CDRX周期中的激活期，接下来三个白色格子为短CDRX周期中的休眠期，12为通过一个短CDRX周期计时器计时下的三个短CDRX周期；20表示一个长CDRX周期，21表示该长CDRX周期中的激活期，接下来的八个白色格子为长CDRX周期中的休眠期。即，一个短CDRX周期为5个子帧，激活期为2个子帧，休眠期为3个子帧；一个长CDRX周期为10个子帧，激活期为2个子帧，休眠期为8个子帧。Please refer to FIG. 3 , which is a schematic diagram of a CDRX cycle disclosed in an embodiment of the present invention; wherein, a CDRX cycle consists of an activation period (On Duration) and a dormancy period (Opportunity for DRX), and during the activation period, the terminal device monitors and receives PDCCH; During the sleep period, the terminal device does not receive the PDCCH to reduce power consumption, but can receive data from other physical channels, such as the Physical Downlink Share Channel (PDSCH), ACK/NACK, etc. From the time domain point of view, time is divided into successive CDRX cycles (CDRX Cycle). The choice of CDRX cycle needs to consider the balance between battery saving and delay. Battery usage time, for example, in the process of web browsing, when the user is reading the downloaded web page, it is a waste of resources for the terminal device to continuously receive downlink data; on the other hand, when there is new data transmission, a more A short CDRX cycle is beneficial for a faster response, for example, when the user requests another web page or makes a VoIP call. To meet the above requirements of terminal devices, each terminal device can be configured with two CDRX cycles: a short CDRX cycle (shortRCX-Cycle) and a long CDRX cycle (longDRX-Cycle). If the terminal device is configured with a short CDRX cycle, the long CDRX cycle should be configured as a multiple of the short CDRX cycle. But at any one time, the terminal device can only use one of these configurations. In Figure 3, 10 represents a short CDRX cycle, 11 represents the active period in the short CDRX cycle, the next three white squares are the sleep period in the short CDRX cycle, and 12 is the three-time period counted by a short CDRX cycle timer. A short CDRX cycle; 20 represents a long CDRX cycle, 21 represents the active period in the long CDRX cycle, and the next eight white boxes are the sleep period in the long CDRX cycle. That is, a short CDRX cycle is 5 subframes, the active period is 2 subframes, and the dormant period is 3 subframes; a long CDRX cycle is 10 subframes, the active period is 2 subframes, and the dormant period is 8 subframes.
在图3中，终端设备在无线帧的0号子帧中有DCI数据收发完之后，在1-3号子帧中如果一直没有数据进行收发，进入短CDRX周期，在3个短CDRX周期后，如果PDCCH信道中一直没有终端设备的DCI信息，将进入到长CDRX周期。CDRX周期中定义了多个定时器(timer)，如CDRX非激活定时器(drx-InactivityTimer)和激活定时器(OnDuration Timer)，其中：In Figure 3, after the terminal device has received and received DCI data in subframe 0 of the radio frame, if there is no data to send and receive in subframes 1-3, it enters a short CDRX cycle, and after 3 short CDRX cycles , if there is no DCI information of the terminal equipment in the PDCCH channel, it will enter the long CDRX cycle. Multiple timers (timers) are defined in the CDRX cycle, such as the CDRX inactivity timer (drx-InactivityTimer) and the activation timer (OnDuration Timer), where:
激活定时器(OnDuration Timer)：指定每个CDRX周期开始时，终端设备持续监听的PDCCH子帧数；Activation timer (OnDuration Timer): Specify the number of PDCCH subframes that the terminal device continues to monitor at the beginning of each CDRX cycle;
CDRX非激活定时器(drx-InactivityTimer)：指定在激活期期间，当终端设备成功解码一个指示上下行用户数据初传的PDCCH后，持续处于CDRX激活期的连续PDCCH子帧数。CDRX inactivity timer (drx-InactivityTimer): Specifies the number of consecutive PDCCH subframes that remain in the CDRX active period after the terminal device successfully decodes a PDCCH indicating the initial transmission of uplink and downlink user data during the active period.
每当终端设备被调度以初传数据时，就会启动(或重启)一个CDRX非激活定时器，终端设备将一直处于激活态直到定时器超时。Whenever a terminal device is scheduled to initially transmit data, a CDRX inactivity timer is started (or restarted), and the terminal device will remain active until the timer expires.
结合上述介绍，本发明实施例提供了一种天线控制方法、装置及终端设备，用于在CDRX非激活定时器计时超时后，说明暂时没有终端设备的下行数据，通过获取终端设备工作在单天线模式时的第一信号参数，如果第一信号参数匹配终端设备对应的服务小区的小区信号参数，将终端设备的天线模式从多天线模式切换至单天线模式，能够减少因打开多个天线带来的功耗损失，延长终端设备的待机时长。下面将从终端设备角度出发并结合具体实施例，对本发明技术方案进行详细介绍。Combined with the above introduction, the embodiments of the present invention provide an antenna control method, apparatus, and terminal equipment, which are used to indicate that there is no downlink data of the terminal equipment temporarily after the CDRX inactivity timer expires, and the terminal equipment works on a single antenna by obtaining The first signal parameter in the mode, if the first signal parameter matches the cell signal parameter of the serving cell corresponding to the terminal device, switching the antenna mode of the terminal device from the multi-antenna mode to the single-antenna mode can reduce the problems caused by opening multiple antennas. The power consumption is lost and the standby time of the terminal device is prolonged. The technical solutions of the present invention will be described in detail below from the perspective of terminal equipment and in conjunction with specific embodiments.
请参阅图4，图4为本发明实施例一公开的天线控制方法的流程示意图；如图4所示，该天线控制方法可包括：Please refer to FIG. 4, which is a schematic flowchart of an antenna control method disclosed in Embodiment 1 of the present invention; as shown in FIG. 4, the antenna control method may include:
401、在终端设备处于RRC连接状态下，若检测到CDRX非激活定时器计时超时后，获取终端设备工作在单天线模式时的第一信号参数。401. When the terminal device is in the RRC connection state, if it is detected that the CDRX inactivation timer times out, obtain the first signal parameter when the terminal device works in the single-antenna mode.
可选的，第一信号参数可以包括信号强度、信号质量和信噪比中的至少一种。Optionally, the first signal parameter may include at least one of signal strength, signal quality, and signal-to-noise ratio.
其中，终端设备在RRC连接时，天线模式通常为多天线模式。终端设备通过设置CDRX非激活定时器来检测是否没有用户的下行数据，如果CDRX非激活定时器超时，说明没有用户的下行数据，可以进入到CDRX机制，即进入CDRX周期。同时，在没有用户的下行数据之后，可以检测终端设备工作在单天线模式时的第一信号参数，以判断终端设备是否可以切换单天线模式，以节省用电。Wherein, when the terminal device is connected to RRC, the antenna mode is usually a multi-antenna mode. The terminal device detects whether there is no downlink data of the user by setting the CDRX inactivation timer. If the CDRX inactivation timer expires, it means that there is no downlink data of the user, and can enter the CDRX mechanism, that is, enter the CDRX cycle. At the same time, after there is no downlink data from the user, the first signal parameter of the terminal device operating in the single-antenna mode can be detected to determine whether the terminal device can switch the single-antenna mode to save electricity.
示例性的，在图3中，在1-3号子帧之后，CDRX非激活定时器超时，获取终端设备工作在单天线模式时的第一信号参数。Exemplarily, in FIG. 3 , after subframes 1-3, the CDRX inactivation timer expires, and the first signal parameter when the terminal device operates in the single-antenna mode is acquired.
402、若上述第一信号参数匹配终端设备对应的服务小区的小区信号参数，将终端设备的天线模式从多天线模式切换至单天线模式。402. If the above-mentioned first signal parameters match the cell signal parameters of the serving cell corresponding to the terminal device, switch the antenna mode of the terminal device from the multi-antenna mode to the single-antenna mode.
其中，若第一信号参数匹配终端设备对应的服务小区的小区信号参数，说明终端设备工作在单天线模式也可以满足服务小区的信号需求，因此，可以通过切换至单天线模式以降低终端设备的功耗，达到延长终端设备的待机时长的目的。Wherein, if the first signal parameter matches the cell signal parameter of the serving cell corresponding to the terminal device, it means that the terminal device can also meet the signal requirements of the serving cell even when the terminal device operates in the single-antenna mode. Therefore, switching to the single-antenna mode can reduce the Power consumption to achieve the purpose of extending the standby time of the terminal device.
可选的，上述多天线模式可以为双天线模式，或者三天线及以上模式。Optionally, the above-mentioned multi-antenna mode may be a dual-antenna mode, or a three-antenna mode or more.
作为一种可选的实施方式，在终端设备处于无线资源控制RRC连接状态下，若检测到非连续接收CDRX非激活定时器计时超时后，获取终端设备工作在单天线模式时的第一信号参数，包括：As an optional implementation manner, when the terminal device is in the RRC connection state, if it is detected that the discontinuous reception CDRX inactivity timer expires, the first signal parameter of the terminal device operating in the single-antenna mode is obtained. ,include:
在终端设备处于无线资源控制RRC连接状态下，若检测到非连续接收CDRX非激活定时器计时超时后，获取终端设备当前工作在多天线模式时的第一信号强度值；When the terminal device is in the radio resource control RRC connection state, if it is detected that the discontinuous reception CDRX inactivation timer expires, obtain the first signal strength value when the terminal device is currently working in the multi-antenna mode;
以及，获取终端设备的天线模式从多天线模式切换至单天线模式对应的信号强度衰减值；And, acquiring the signal strength attenuation value corresponding to the switching of the antenna mode of the terminal device from the multi-antenna mode to the single-antenna mode;
根据第一信号强度值和信号强度衰减值，获得终端设备工作在单天线模式 时的第二信号强度值；According to the first signal strength value and the signal strength attenuation value, obtain the second signal strength value when the terminal device works in the single antenna mode;
判断第二信号强度值是否匹配终端设备对应的服务小区的最小接入强度值。Determine whether the second signal strength value matches the minimum access strength value of the serving cell corresponding to the terminal device.
可以看出，上述实施方式主要通过判断终端设备工作在单天线模式下其信号强度是否满足服务小区的最小接入强度值，以确定是否可以切换至单天线模式。It can be seen that, in the above-mentioned embodiments, whether the terminal device can switch to the single-antenna mode is determined mainly by judging whether the signal strength of the terminal device in the single-antenna mode meets the minimum access strength value of the serving cell.
进而，若第一信号参数匹配终端设备对应的服务小区的小区信号参数，将终端设备的天线模式从多天线模式切换至单天线模式，包括：Furthermore, if the first signal parameter matches the cell signal parameter of the serving cell corresponding to the terminal device, switching the antenna mode of the terminal device from the multi-antenna mode to the single-antenna mode includes:
若第二信号强度值匹配最小接入强度值，将终端设备的天线模式从多天线模式切换至单天线模式。If the second signal strength value matches the minimum access strength value, switch the antenna mode of the terminal device from the multi-antenna mode to the single-antenna mode.
举例来说，终端设备工作在双天线模式时，信号强度值为120dBm，双天线模式到单天线模式的信号强度衰减值为10dBm，因此，终端设备工作在单天线模式时，信号强度值为110dBm，如果服务小区的最小接入强度值为120dBm，则说明终端设备工作在单天线模式时无法满足服务小区的需求，不能进行切换，以免终端设备无法正常接入网络；如果服务小区的最下接入强度值为110dBm，则说明终端设备工作在单天线模式时刚好满足服务小区的需求，可以将终端设备的天线模式从多天线模式切换至单天线模式，以降低功耗。For example, when the terminal device works in the dual-antenna mode, the signal strength value is 120dBm, and the signal strength attenuation value from the dual-antenna mode to the single-antenna mode is 10dBm. Therefore, when the terminal device works in the single-antenna mode, the signal strength value is 110dBm , if the minimum access strength value of the serving cell is 120dBm, it means that the terminal device cannot meet the needs of the serving cell when it works in the single antenna mode, and cannot perform handover, so as to prevent the terminal device from being unable to access the network normally; If the input strength value is 110dBm, it means that the terminal device works in the single-antenna mode just to meet the needs of the serving cell, and the antenna mode of the terminal device can be switched from the multi-antenna mode to the single-antenna mode to reduce power consumption.
实施上述实施例，终端设备处于RRC连接状态时天线模式为多天线模式，通过在CDRX非激活定时器计时超时后，获取终端设备工作在单天线模式时的第一信号参数，如果第一信号参数匹配终端设备对应的服务小区的小区信号参数，将终端设备的天线模式从多天线模式切换至单天线模式，可以看出，实施本发明实施例，在CDRX非激活定时器计时超时后，说明暂时没有终端设备的下行数据，而第一信号参数匹配终端设备对应的服务小区的小区信号参数，说明终端设备工作在单天线模式能够满足服务小区的信号需求，因此，可以将终端设备的天线模式从多天线模式切换至单天线模式，从而能够减少因打开多个天线带来的功耗损耗，延长终端设备的待机时长。Implementing the above embodiment, when the terminal device is in the RRC connection state, the antenna mode is the multi-antenna mode, and after the CDRX inactivity timer times out, the first signal parameters of the terminal device operating in the single-antenna mode are obtained. If the first signal parameter Match the cell signal parameters of the serving cell corresponding to the terminal device, and switch the antenna mode of the terminal device from the multi-antenna mode to the single-antenna mode. There is no downlink data of the terminal device, and the first signal parameters match the cell signal parameters of the serving cell corresponding to the terminal device, indicating that the terminal device works in the single-antenna mode and can meet the signal requirements of the serving cell. Therefore, the antenna mode of the terminal device can be changed from The multi-antenna mode is switched to the single-antenna mode, which can reduce the power consumption caused by opening multiple antennas and prolong the standby time of the terminal device.

501、在终端设备处于无线资源控制RRC连接状态下，若检测到CDRX非激活定时器计时超时后，获取终端设备工作在单天线模式时的第一信号参数。501. When the terminal device is in the radio resource control RRC connection state, if it is detected that the CDRX inactivity timer times out, obtain the first signal parameter when the terminal device operates in the single-antenna mode.
作为一种可选的实施方式，在终端设备处于无线资源控制RRC连接状态下，若检测到CDRX非激活定时器计时超时后，获取指示当前信道质量的参数值，如终端设备当前缓冲区待发送数据中的重传数据比例或者终端设备的接收信号强度；若参数值小于预先设置的阈值，维持终端设备的天线模式为多天线模式，若参数值大于预先设置的预置，执行获取终端设备工作在单天线模式时的第一信号参数的步骤；若参数值等于预先设置的阈值，可以执行维持终端 设备的天线模式为多天线模式的步骤或者执行获取终端设备工作在单天线模式时的第一信号参数的步骤。As an optional implementation manner, when the terminal device is in the RRC connection state, if it is detected that the CDRX inactivity timer expires, the parameter value indicating the current channel quality is obtained, such as the current buffer of the terminal device to be sent.
