Description
技术领域technical field
本发明涉及移动通信技术领域,尤其涉及一种业务调度方法、设备和系统。The present invention relates to the technical field of mobile communication, in particular to a service scheduling method, device and system.
背景技术Background technique
长期演进(Long Term Evolution,LTE)技术是3G技术的演进。LTE改进并增强了3G的空中接入技术,在20MHz频谱带宽下能够提供下行100Mbit/s与上行50Mbit/s的峰值速率,改善了小区边缘用户的性能,提高小区容量和降低系统延迟,因此,LTE技术得到了业界广泛的认可,运营商开始大力部署LTE网络。Long Term Evolution (LTE) technology is the evolution of 3G technology. LTE improves and enhances the 3G air access technology. Under the 20MHz spectrum bandwidth, it can provide a peak rate of downlink 100Mbit/s and uplink 50Mbit/s, which improves the performance of cell edge users, increases cell capacity and reduces system delay. Therefore, LTE technology has been widely recognized by the industry, and operators have begun to vigorously deploy LTE networks.
媒体流(MediaFLO)技术是美国高通公司对于移动电话、个人数字助理等可携式装备的广播资料传送技术。广播资料包含多样性的即时影音串流、独立或是非即时的影音“短片”,如股市的走势、体育赛事的分数,以及气象报道等IP数据广播应用服务。MediaFLO系统是从现有的移动网络的频谱使用中所分割的一块传递数据,例如,美国使用的MediaFLO的频谱是716-722MHz。MediaFLO (MediaFLO) technology is the broadcast data transmission technology of Qualcomm for mobile phones, personal digital assistants and other portable equipment. The broadcast data includes a variety of real-time video streams, independent or non-real-time video "short films", such as stock market trends, sports scores, and IP data broadcasting applications such as weather reports. The MediaFLO system is a piece of transmission data divided from the spectrum usage of the existing mobile network. For example, the spectrum of MediaFLO used in the United States is 716-722MHz.
当运营商使用存在MediaFLO广播的频段构建LTE网络时,例如,美国运营商AT&T和Verizon使用存在MediaFLO广播的700MHz频段构建LTE网络,一种双模终端应运而生。如图1所示,显示了一种典型的双模终端,这种双模终端中集成了LTE双工机和MediaFLO接收器,该LTE双工机用于LTE数据的发送/接收(TX/RX),该MediaFLO接收器用于接收MediaFLO广播,LTE双工机和MediaFLO接收器共用同一天线。When operators build LTE networks using frequency bands where MediaFLO broadcasts exist, for example, US operators AT&T and Verizon use 700MHz frequency bands where MediaFLO broadcasts exist to build LTE networks, and a dual-mode terminal emerges as the times require. As shown in Figure 1, a typical dual-mode terminal is shown. An LTE duplexer and a MediaFLO receiver are integrated in this dual-mode terminal. The LTE duplexer is used for transmitting/receiving LTE data (TX/RX ), the MediaFLO receiver is used to receive MediaFLO broadcasts, and the LTE duplexer and the MediaFLO receiver share the same antenna.
在实现本发明的过程中,发明人发现现有技术中至少存在如下问题:In the process of realizing the present invention, the inventor finds that there are at least the following problems in the prior art:
上述包含LTE双工机和MediaFLO接收器的双模终端,在上行方向发送LTE数据时会对MediaFLO广播的接收产生自干扰。例如,若MediaFLO广播的带宽是6MHz,有效带宽为5.6MHz,MediaFLO接收器的噪声系数是8dB,这种场景下,可以计算出共用天线的LTE双工机和MediaFLO接收器之间所需的隔离度为80dB,否则,影响双模终端的正常运行。若通过在终端中插入额外的设备实现上述隔离度,这种插入处理对现有终端损耗很大,需要增加终端中处理芯片的体积和功能,对终端的要求过高且成本很大,在实际应用中不可行。亟待一种解决上述双模终端中自干扰问题的方法。The aforementioned dual-mode terminal including an LTE duplexer and a MediaFLO receiver will generate self-interference to the reception of MediaFLO broadcasts when transmitting LTE data in the uplink direction. For example, if the MediaFLO broadcast bandwidth is 6MHz, the effective bandwidth is 5.6MHz, and the noise figure of the MediaFLO receiver is 8dB, in this scenario, the isolation required between the LTE duplexer and the MediaFLO receiver sharing the antenna can be calculated The degree is 80dB, otherwise, it will affect the normal operation of the dual-mode terminal. If the above-mentioned isolation is achieved by inserting additional devices into the terminal, this kind of insertion process will cause a lot of loss to the existing terminal, and it is necessary to increase the size and function of the processing chip in the terminal. The requirements for the terminal are too high and the cost is very high. Not feasible in application. There is an urgent need for a method for solving the self-interference problem in the above-mentioned dual-mode terminal.

Moreover, the technical solution of the embodiment of the present invention does not need to add additional equipment to the terminal, fully utilizes existing resources, consumes little cost, and has great feasibility in practical applications.
下面对本发明实施例四提供的技术方案进行详细介绍。The technical solution provided by Embodiment 4 of the present invention will be described in detail below.
本发明实施例四提供的技术方案,可由网络侧的相关网元获取业务调度信息,根据该业务调度信息,调度终端在执行第一业务时不执行第二业务,以避免第一业务和第二业务同时存在时产生冲突而带来的问题,如自干扰现象,或者由终端侧进行控制以避免第一业务和第二业务同时存在时产生冲突而带来的问题,如自干扰现象。其中,上述第一业务为无线通信数据的上行发送,上述第二业务为广播数据的接收;或者,上述第一业务为广播数据的接收,上述第二业务为无线通信数据的上行发送。According to the technical solution provided by Embodiment 4 of the present invention, relevant network elements on the network side can obtain service scheduling information. According to the service scheduling information, the scheduling terminal does not perform the second service when executing the first service, so as to avoid the first service and the second service. Problems caused by conflicts when services exist at the same time, such as self-interference phenomenon, or problems caused by conflicts caused by the simultaneous existence of the first service and the second service by controlling on the terminal side, such as self-interference phenomenon. Wherein, the above-mentioned first service is uplink transmission of wireless communication data, and the above-mentioned second service is reception of broadcast data; or, the above-mentioned first service is reception of broadcast data, and the above-mentioned second service is uplink transmission of wireless communication data.
情况一:由网络侧进行控制以避免自干扰现象Case 1: Controlled by the network side to avoid self-interference
首先,网络侧的相关网元,如演进的基站(eNB),需要获取到业务调度信息。上述业务调度信息可以为与第一业务相关的调度信息,或者包括与第二业务相关的调度信息,或者为与第一业务和第二业务相关的调度信息。第一业务和第二业务为两种同时存在时会产生冲突,对终端造成影响,如自干扰,而需要调度的任意两种可能的业务。First, relevant network elements on the network side, such as evolved base stations (eNBs), need to obtain service scheduling information. The foregoing service scheduling information may be scheduling information related to the first service, or include scheduling information related to the second service, or be scheduling information related to the first service and the second service. The first service and the second service are any two possible services that may conflict when they exist at the same time and cause impact on the terminal, such as self-interference, and need to be scheduled.
在本发明实施例中,主要以调度LTE中的数据的上行发送业务和MediaFLO数据的接收业务的场景为例进行说明。进一步的,本发明实施例中上述业务的调度信息选取与MediaFLO相关的业务调度信息。但不限于此,例如,本技术方案可适用于其它上行数据的发送与下行数据的接收相干扰的场景,如上述的广播数据还可以为多媒体广播组播业务(MBMS)数据、手持数字视频广播(DVB-H)数据、地面数字多媒体广播(DMB)或者综合业务数字广播-地面传输(ISDB-T)数据等其他广播数据。In the embodiment of the present invention, the scenario of scheduling the uplink transmission service of data in LTE and the reception service of MediaFLO data is mainly used as an example for description. Further, in the embodiment of the present invention, the above service scheduling information selects the service scheduling information related to MediaFLO. But not limited thereto, for example, this technical solution can be applied to other scenarios where the transmission of uplink data interferes with the reception of downlink data, such as the above-mentioned broadcast data can also be multimedia broadcast multicast service (MBMS) data, handheld digital video broadcasting (DVB-H) data, terrestrial digital multimedia broadcasting (DMB) or integrated services digital broadcasting-terrestrial transmission (ISDB-T) data and other broadcast data.
示例性的,上述业务调度信息可以包含终端接收MediaFLO数据的起始时刻(Start)和持续时间(Duration),或者,上述的业务调度信息可以包含终端接收MediaFLO数据的起始时刻和终止时刻。在终端每次接收MediaFLO业务之前,基站获取该业务调度信息。Exemplarily, the above service scheduling information may include the start time (Start) and duration (Duration) of the terminal receiving the MediaFLO data, or the above service scheduling information may include the start time and end time of the terminal receiving the MediaFLO data. Before the terminal receives the MediaFLO service each time, the base station acquires the service scheduling information.
进一步的,当MediaFLO数据是周期性发送的,且每个周期中MediaFLO数据的时间信息一样时,上述业务调度信息可以包含终端接收MediaFLO数据的起始时刻(Start)、持续时间(Duration)和周期(Period),或者,上述的业务调度信息可以包含终端接收MediaFLO数据的起始时刻、终止时刻和周期,基站只需获取一次该业务调度信息,即可获知终端接收MediaFLO数据的时间信息。Further, when the MediaFLO data is sent periodically, and the time information of the MediaFLO data in each period is the same, the above service scheduling information may include the start time (Start), duration (Duration) and period of the terminal receiving the MediaFLO data (Period), or, the above-mentioned service scheduling information may include the start time, end time and period of the terminal receiving the MediaFLO data, and the base station only needs to obtain the service scheduling information once to know the time information of the terminal receiving the MediaFLO data.
但不限于此,该调度信息可以包含eNB进行业务调度时,所需的任何指示终端接收MediaFLO数据的时间信息。But not limited thereto, the scheduling information may include any time information required by the eNB to instruct the terminal to receive the MediaFLO data when the eNB performs service scheduling.
eNB可通过多种方式获取到上述MediaFLO的业务调度信息,例如,至少包括如下两种方式:The eNB can obtain the above-mentioned MediaFLO service scheduling information in a variety of ways, for example, at least including the following two ways:
方式一、接收终端发送的MediaFLO的业务调度信息Method 1: Receive the service scheduling information of MediaFLO sent by the terminal
eNB接收终端发送的上述MediaFLO的业务调度信息。The eNB receives the above-mentioned MediaFLO service scheduling information sent by the terminal.
可以新增一条专用信令,终端通过该新增的专用信令将MediaFLO的业务调度信息发送给eNB。终端的运行机制保证了终端可以获知该MediaFLO的业务调度信息。例如,终端接收到系统中的系统消息或广播信令时,解析该系统消息或广播信令,获取到相应的MediaFLO的业务调度信息,或者,终端从接收到的MediaFLO数据包中获取相应的MediaFLO的业务调度信息,这时,MediaFLO数据包中携带了控制信息包,该控制信息包中包含上述MediaFLO的业务调度信息。A dedicated signaling can be added, and the terminal sends the service scheduling information of MediaFLO to the eNB through the newly added dedicated signaling. The operating mechanism of the terminal ensures that the terminal can obtain the service scheduling information of the MediaFLO. For example, when the terminal receives a system message or broadcast signaling in the system, it parses the system message or broadcast signaling to obtain the corresponding MediaFLO service scheduling information, or the terminal obtains the corresponding MediaFLO from the received MediaFLO packet. At this time, the MediaFLO data packet carries a control information packet, and the control information packet includes the above-mentioned MediaFLO service scheduling information.
方式二、接收终端发送的业务指示信息,根据所述业务指示信息获取已保存的所述业务调度信息。Mode 2: Receive service indication information sent by the terminal, and acquire the stored service scheduling information according to the service indication information.
这种方式中,eNB对需进行调度的MediaFLO的业务调度信息提前进行存储。终端只需上报MediaFLO的业务指示信息,eNB根据该业务指示信息查询已保存的所有业务调度信息,并读取匹配的业务调度信息。In this manner, the eNB stores the service scheduling information of the MediaFLO that needs to be scheduled in advance. The terminal only needs to report the service indication information of MediaFLO, and the eNB queries all the stored service scheduling information according to the service indication information, and reads the matching service scheduling information.
以6MHz带宽为例,MediaFLO可以提供20个300kbps的Mobile TV业务,为每个Mobile TV业务设置标识,eNB获取并保存该20个Mobile TV业务的业务调度信息,并保存Mobile TV业务与标识的对应关系,将该标识作为业务指示信息,终端只需上报该标识,eNB根据接收到的标识查询对应关系,即可获取到相应的MediaFLO的业务调度信息。Taking the 6MHz bandwidth as an example, MediaFLO can provide 20 300kbps Mobile TV services, and set an identifier for each Mobile TV service. The eNB obtains and saves the service scheduling information of the 20 Mobile TV services, and saves the correspondence between the Mobile TV service and the identifier. relationship, the identification is used as service indication information, the terminal only needs to report the identification, and the eNB queries the corresponding relationship according to the received identification, and can obtain the corresponding service scheduling information of MediaFLO.
下面对eNB利用上述业务调度信息执行控制处理,以避免终端接收MediaFLO数据时进行LTE系统中的上行数据的发送的情况进行说明。在此,需要发送的LTE系统中的上行数据包括LTE系统中任何由终端发送至eNB的上行数据信息,通过对下述示例性的LTE系统中上行数据发送的描述,本领域技术人员可以清楚获知对所有LTE数据的上行发送场景的控制方法。下面针对终端在不同的上行信道中进行数据和信号的发送,分别进行如下处理:The following describes the situation where the eNB uses the above service scheduling information to perform control processing to avoid sending uplink data in the LTE system when the terminal receives MediaFLO data. Here, the uplink data in the LTE system that needs to be sent includes any uplink data information sent by the terminal to the eNB in the LTE system. Through the description of the following exemplary uplink data transmission in the LTE system, those skilled in the art can clearly understand A control method for uplink transmission scenarios of all LTE data. The following processes are performed respectively for the terminal to send data and signals in different uplink channels:
(1)物理上行共享信道(PUSCH):(1) Physical Uplink Shared Channel (PUSCH):
在PUSCH上发送的数据包括动态调度数据和半静态调度数据。Data sent on the PUSCH includes dynamic scheduling data and semi-persistent scheduling data.
对动态调度数据,在每一次进行该动态调度数据的发送时,首先终端向eNB发送资源请求指示(Source Request Indicator,SRI)消息,eNB根据该SRI消息发送物理下行控制信道(PDCCH)信令,控制终端PUSCH动态调度数据的发送。For dynamic scheduling data, each time the dynamic scheduling data is sent, the terminal first sends a Resource Request Indicator (Source Request Indicator, SRI) message to the eNB, and the eNB sends Physical Downlink Control Channel (PDCCH) signaling according to the SRI message, The control terminal PUSCH dynamically schedules the sending of data.
本发明实施例中,eNB根据业务调度信息控制MediaFLO数据的接收与PUSCH动态调度数据的上行发送,如图4所示,具体包括如下步骤:In the embodiment of the present invention, the eNB controls the reception of MediaFLO data and the uplink transmission of PUSCH dynamic scheduling data according to the service scheduling information, as shown in Figure 4, specifically including the following steps:
步骤T1:eNB接收终端发送的MediaFLO的业务调度信息。Step T1: The eNB receives the service scheduling information of MediaFLO sent by the terminal.
该业务调度信息指示了终端接收MediaFLO数据的时间信息,例如,该业务调度信息为终端接收MediaFLO数据的起始时刻和持续时间,或该业务调度信息为终端接收MediaFLO数据的起始时刻和终止时刻。The service scheduling information indicates the time information for the terminal to receive MediaFLO data, for example, the service scheduling information is the start time and duration of the terminal receiving MediaFLO data, or the service scheduling information is the start time and end time of the terminal receiving MediaFLO data .
步骤T2:终端需要进行PUSCH动态调度数据的上行发送时,终端向eNB发送SRI消息,请求eNB允许该动态调度数据的发送。Step T2: When the terminal needs to perform uplink transmission of PUSCH dynamic scheduling data, the terminal sends an SRI message to the eNB, requesting the eNB to allow the transmission of the dynamic scheduling data.
步骤T3:eNB接收到上述SRI消息后,根据业务调度信息进行调度。Step T3: After receiving the above SRI message, the eNB performs scheduling according to the service scheduling information.
若eNB根据业务调度信息判断出在发送该动态调度数据时,终端在进行MediaFLO业务的接收,即该动态调度数据的上行发送与MediaFLO数据的接收相冲突时,则该调度结果可以为拒绝终端进行上述动态调度数据的发送。若该动态数据的上行发送与MediaFLO数据的接收不冲突,则该调度结果可以为允许上述动态数据的发送。If the eNB judges according to the service scheduling information that when sending the dynamic scheduling data, the terminal is receiving the MediaFLO service, that is, when the uplink sending of the dynamic scheduling data conflicts with the receiving of the MediaFLO data, the scheduling result can be that the terminal is rejected. The sending of the above-mentioned dynamic scheduling data. If the uplink sending of the dynamic data does not conflict with the receiving of the MediaFLO data, the scheduling result may be to allow the sending of the dynamic data.
进一步的,若该动态调度数据具有较高的重要性,则优先处理该动态数据的上行发送,这时,调度结果为终端停止接收MediaFLO数据,进行动态调度数据的上行发送。Further, if the dynamic scheduling data is of high importance, the uplink transmission of the dynamic data is prioritized. At this time, the scheduling result is that the terminal stops receiving MediaFLO data and performs uplink transmission of the dynamic scheduling data.
步骤T4:eNB向终端发送PDCCH信令,该PDCCH信令携带上述调度结果。Step T4: The eNB sends PDCCH signaling to the terminal, and the PDCCH signaling carries the above scheduling result.
步骤T5:终端根据解析接收到的PDCCH信令,获知调度结果。Step T5: The terminal obtains the scheduling result by analyzing the received PDCCH signaling.
当调度结果为允许上述动态调度数据的上行发送时,向eNB发送PUSCH数据。或者,当调度结果为拒绝上述动态调度数据的上行发送时,不进行PUSCH数据的发送;或者,当调度结果为停止接收MediaFLO数据且发送上述动态调度数据时,终端停止接收MediaFLO数据以发送该动态调度数据。When the scheduling result is that the uplink transmission of the dynamic scheduling data is allowed, the PUSCH data is sent to the eNB. Or, when the scheduling result is to reject the uplink transmission of the dynamic scheduling data, do not send the PUSCH data; or, when the scheduling result is to stop receiving MediaFLO data and send the dynamic scheduling data, the terminal stops receiving MediaFLO data to send the dynamic Scheduling data.
对半静态调度数据,在第一次进行该数据的发送时,终端向eNB发送SRI消息,eNB根据该SRI消息向终端发送PDCCH信令,在该PDCCH信令中对半静态调度数据的发送周期和时间等进行配置,终端根据PDCCH信令中的配置发送该半静态调度数据。在后续处理过程中,终端直接根据配置的发送周期和时间等,执行该半静态调度数据的发送,无需再利用SRI消息向eNB进行请求。For semi-persistent scheduling data, when the data is sent for the first time, the terminal sends an SRI message to the eNB, and the eNB sends PDCCH signaling to the terminal according to the SRI message, and the sending period of the semi-persistent scheduling data in the PDCCH signaling and time are configured, and the terminal sends the semi-persistent scheduling data according to the configuration in the PDCCH signaling. During subsequent processing, the terminal directly executes the sending of the semi-persistently scheduled data according to the configured sending period and time, without using the SRI message to request the eNB.
在本发明实施例中,eNB根据业务调度信息获知,当终端进行该半静态调度数据的上行发送时,存在MediaFLO数据的接收业务,则eNB通过重新向终端发送PDCCH信令对半静态调度数据的发送周期和时间重新进行设置,调整半静态调度数据的发送周期和时间等,以避开MediaFLO数据的接收,使半静态调度数据的上行发送与MediaFLO数据的接收不冲突,从而避免了自干扰现象的发生。In the embodiment of the present invention, the eNB learns from the service scheduling information that when the terminal performs the uplink transmission of the semi-persistently scheduled data, there is a service for receiving MediaFLO data, and the eNB retransmits the PDCCH signaling to the terminal for semi-persistently scheduled data. Re-set the sending cycle and time, adjust the sending cycle and time of semi-statically scheduled data, etc., to avoid the reception of MediaFLO data, so that the uplink sending of semi-statically scheduled data does not conflict with the reception of MediaFLO data, thereby avoiding self-interference happened.
上述PUSCH数据的上行发送还可跟随有参考信号(RS)的上行发送,这时对RS的处理方式可参见对上述PUSCH数据的处理方式。The above-mentioned uplink transmission of the PUSCH data may also be followed by uplink transmission of a reference signal (RS), at this time, the processing method for the RS may refer to the above-mentioned processing method for the PUSCH data.
(2)物理上行控制信道(PUCCH)(2) Physical Uplink Control Channel (PUCCH)
PUCCH信令可以是伴随PUSCH信令发送的,这种情况下调度的方法参见对上行发送的PUSCH数据的调度方法。The PUCCH signaling may be sent along with the PUSCH signaling. In this case, for the scheduling method, refer to the scheduling method for the PUSCH data sent uplink.
进一步的,PUCCH信令也可以用于确认/非确认(ACK/NACK)消息,信道质量指示(CQI)消息,SRI消息或RS的上行发送。Further, the PUCCH signaling can also be used for uplink transmission of acknowledgment/non-acknowledgement (ACK/NACK) messages, channel quality indication (CQI) messages, SRI messages or RSs.
对ACK/NACK消息,这两种消息是终端对eNB发送的物理下行共享信道(PDSCH)数据的反馈消息,ACK消息表示接收PDSCH数据成功,NACK消息表示接收PDSCH数据失败。eNB可根据设置得到其所发送的PDSCH数据和终端反馈的ACK/NACK消息之间的时序关系,并根据这种时序关系判断终端在接收MediaFLO数据的同时是否会出现需要发送ACK/NACK消息的情况,若存在这种情况,则eNB不再进行相应PDSCH数据的发送。For the ACK/NACK message, these two messages are feedback messages sent by the terminal to the physical downlink shared channel (PDSCH) data sent by the eNB. The ACK message indicates that the PDSCH data is successfully received, and the NACK message indicates that the PDSCH data is failed to be received. The eNB can obtain the timing relationship between the PDSCH data it sends and the ACK/NACK message fed back by the terminal according to the settings, and judge whether the terminal needs to send an ACK/NACK message while receiving MediaFLO data according to this timing relationship , if this situation exists, the eNB will no longer send the corresponding PDSCH data.
在LTE的频分双工(FDD)系统中,终端通过PUCCH信令在n时刻反馈的ACK/NACK消息,对应于eNB在(n-4)时刻发送的PDSCH数据。因此,当eNB要向终端发送PDSCH数据时,根据MediaFLO的业务调度信息判断在4个时刻后,终端需要进行MediaFLO数据的接收时,则eNB不再进行相应PDSCH数据的发送。In the frequency division duplex (FDD) system of LTE, the ACK/NACK message fed back by the terminal at time n through PUCCH signaling corresponds to the PDSCH data sent by the eNB at time (n-4). Therefore, when the eNB wants to send PDSCH data to the terminal, and judges according to the service scheduling information of MediaFLO that the terminal needs to receive MediaFLO data after 4 moments, the eNB will no longer send the corresponding PDSCH data.
在LTE时分双工(TDD)中,终端通过PUCCH信令在n时刻反馈的ACK/NACK,对应于基站在(n-k)时刻向该终端发送的PDSCH数据,对k的取值参见下表:In LTE Time Division Duplex (TDD), the ACK/NACK fed back by the terminal at time n through PUCCH signaling corresponds to the PDSCH data sent by the base station to the terminal at (n-k) time. For the value of k, refer to the following table:
表1Table 1
表1中对不同模式下(模式0至模式6)9种子帧的k的取值进行了说明。表1中最左边的纵列为PDSCH所配置的模式,“-”表示相应子帧为上行的子帧。由表1可知,在模式0下,对子帧2的k的取值为6。这种情况下,当eNB要向终端发送PDSCH数据时,根据MediaFLO的业务调度信息判断在6个时刻后,终端需要进行MediaFLO数据的接收时,则eNB不再进行相应PDSCH数据的发送。Table 1 illustrates the value of k in 9 sub-frames in different modes (mode 0 to mode 6). The leftmost column in Table 1 is the mode configured by the PDSCH, and "-" indicates that the corresponding subframe is an uplink subframe. It can be known from Table 1 that in mode 0, the value of k for subframe 2 is 6. In this case, when the eNB wants to send PDSCH data to the terminal, it is judged according to the service scheduling information of MediaFLO that the terminal needs to receive MediaFLO data after 6 moments, then the eNB will no longer send the corresponding PDSCH data.
进一步的,当上述PDSCH数据具有较高的重要性,可调度终端停止对应时刻MediaFLO数据的接收,在相应时刻向终端发送PDSCH数据,如以上述LTE的FDD系统为例,eNB在当前时刻向终端发送PDSCH数据,并调度终端在4个时刻后停止MediaFLO数据的接收,以使终端在4个时刻后发送相应的PUCCH信令消息,如ACK/NACK消息。Further, when the above-mentioned PDSCH data is of high importance, the terminal can be scheduled to stop receiving MediaFLO data at the corresponding time, and send PDSCH data to the terminal at the corresponding time. For example, taking the above-mentioned LTE FDD system as an example, the eNB sends the terminal at the current time Send PDSCH data, and schedule the terminal to stop receiving MediaFLO data after 4 moments, so that the terminal sends corresponding PUCCH signaling messages, such as ACK/NACK messages, after 4 moments.
对于CQI和SRI,其发送周期和时间偏差(offset)都可由eNB进行配置,例如,CQI的周期从2个子帧(subframe)到160个子帧的范围内是可以配置的。For CQI and SRI, both the sending period and time offset (offset) can be configured by the eNB, for example, the period of CQI can be configured within a range from 2 subframes to 160 subframes.
当出现了终端接收MediaFLO业务的同时,按照配置需进行CQI和SRI的上行发送的情况,eNB重新对CQI和SRI的发送周期和offset进行配置,以避开在接收MediaFLO业务的同时进行上行数据的发送。When the terminal receives the MediaFLO service, the uplink transmission of CQI and SRI is required according to the configuration, and the eNB reconfigures the sending cycle and offset of the CQI and SRI to avoid the uplink data transmission while receiving the MediaFLO service. send.
(3)探测参考信号(Sounding Reference Signal,SRS)(3) Sounding Reference Signal (SRS)
SRS设置在一个子帧的最后一个块中,SRS的频域间隔为两个等效子载波。SRS的周期和offset由eNB配置,周期从2个subframe到160个subframe可配置,因此也是可以通过网络侧的eNB对该SRS进行控制的。The SRS is set in the last block of a subframe, and the frequency domain interval of the SRS is two equivalent subcarriers. The period and offset of the SRS are configured by the eNB, and the period can be configured from 2 subframes to 160 subframes. Therefore, the SRS can also be controlled by the eNB on the network side.
当出现了终端接收MediaFLO数据的同时,按照eNB的配置终端需进行SRS的上行发送的情况,eNB重新对SRS的发送周期和offset进行配置,调度终端在接收MediaFLO数据时,不执行SRS的发送,或者,终端停止MediaFLO数据的接收,根据eNB的配置进行SRS的发送,以避开在终端接收MediaFLO数据的同时进行上行数据的发送。When the terminal receives MediaFLO data, the terminal needs to perform SRS uplink transmission according to the eNB configuration, the eNB reconfigures the SRS transmission cycle and offset, and the scheduling terminal does not perform SRS transmission when receiving MediaFLO data. Or, the terminal stops receiving the MediaFLO data, and sends the SRS according to the configuration of the eNB, so as to avoid sending the uplink data while the terminal is receiving the MediaFLO data.
对上述处理中,因调度处理而未能正常发送的信令、数据或消息,可在后续允许的时刻进行重发。In the above processing, signaling, data or messages that cannot be sent normally due to the scheduling processing can be resent at a subsequent allowed time.
情况二:由终端侧进行控制以避免自干扰现象Case 2: Control by the terminal side to avoid self-interference
终端可直接根据获取到的业务调度信息,对该终端上MediaFLO数据的接收和LTE上行数据的发送进行调度。The terminal can directly schedule the reception of MediaFLO data and the transmission of LTE uplink data on the terminal according to the acquired service scheduling information.
终端侧针对不同的上行信道和信号的发送,分别进行如下处理:The terminal side performs the following processing for different uplink channels and signal transmissions:
(1)PUSCH(1)PUSCH
终端在进行MediaFLO数据的接收时,不进行PUSCH数据的发送。终端在接收MediaFLO数据的期间,可以不进行半静态PUSCH数据的发送,或者,当终端接收到来自eNB的PDCCH信令指示发送PUSCH数据,而此时正在接收MediaFLO数据时,终端可以拒绝发送该PUSCH数据,或当PDCCH信令指示该PUSCH数据具有较高的重要性时,终端停止MediaFLO数据的接收,进行PUSCH数据的上行发送。When receiving MediaFLO data, the terminal does not send PUSCH data. During the period of receiving MediaFLO data, the terminal may not send semi-static PUSCH data, or, when the terminal receives PDCCH signaling from the eNB indicating to send PUSCH data, and is receiving MediaFLO data at this time, the terminal may refuse to send the PUSCH data, or when the PDCCH signaling indicates that the PUSCH data is of high importance, the terminal stops receiving MediaFLO data and performs uplink transmission of PUSCH data.
在发送上述PUSCH数据时还可同时发送RS,对RS的处理方式可参见对上述PUSCH数据的处理方式。When sending the above PUSCH data, the RS may also be sent at the same time, for the processing method of the RS, please refer to the processing method of the above PUSCH data.
(2)PUCCH(2)PUCCH
终端在接收MediaFLO数据的期间,不向eNB反馈ACK/NACK消息(eNB可能重传相应的PDSCH)。During receiving MediaFLO data, the terminal does not feed back ACK/NACK messages to the eNB (the eNB may retransmit the corresponding PDSCH).
终端在接收MediaFLO数据的期间,可以不向eNB发送SRI消息请求PUSCH数据的发送,或者,不发送CQI。During the period of receiving MediaFLO data, the terminal may not send an SRI message to the eNB to request sending of PUSCH data, or may not send a CQI.
(3)SRS(3) SRS
终端在接收MediaFLO业务的期间,不发射SRS。During receiving the MediaFLO service, the terminal does not transmit SRS.
(4)物理随机接入信道(PRACH)(4) Physical Random Access Channel (PRACH)
PRACH用于终端与网络建立初始连接的时候向网络发送信令,或者响应网络的寻呼消息,也可以用于发送不连续的数据。eNB对PRACH的子帧进行配置,如表2所示,给出了PRACH的可配置子帧的具体信息。The PRACH is used to send signaling to the network when the terminal establishes an initial connection with the network, or to respond to a paging message from the network, and can also be used to send discontinuous data. The eNB configures the subframe of the PRACH, as shown in Table 2, which provides the specific information of the configurable subframe of the PRACH.
表2Table 2
PRACH数据的发送时机是由终端控制的,终端根据所述业务调度信息,在不接收MediaFLO数据时,进行物理随机接入信道PRACH数据的发送,或者,停止MediaFLO数据的接收,进行PRACH数据的发送。The timing of sending PRACH data is controlled by the terminal. According to the service scheduling information, when the terminal is not receiving MediaFLO data, the terminal sends physical random access channel PRACH data, or stops receiving MediaFLO data and sends PRACH data .
对上述处理中,因调度处理而未能正常发送的信令、数据或消息,可在后续允许的时刻进行重发。In the above processing, signaling, data or messages that cannot be sent normally due to the scheduling processing can be resent at a subsequent allowed time.
本发明实施例提供的技术方案,通过调度处理,调度终端在接收MediaFLO数据时,停止进行LTE中的数据的上行发送,或者,调度终端停止MediaFLO数据的接收,进行LTE中的数据的上行发送,从而避免了上行方向上发送的LTE中的数据对MediaFLO广播的接收产生自干扰,影响终端的运行。并且,本发明实施例的技术方案无需在终端中添加额外的设备,充分利用了现有资源,成本消耗很小,在实际应用中具有较大的可行性。In the technical solution provided by the embodiments of the present invention, through scheduling processing, when the scheduling terminal receives MediaFLO data, it stops uplink transmission of data in LTE, or the scheduling terminal stops receiving MediaFLO data, and performs uplink transmission of data in LTE. Therefore, it is avoided that the data in the LTE transmitted in the uplink direction causes self-interference to the reception of the MediaFLO broadcast, which affects the operation of the terminal. Moreover, the technical solution of the embodiment of the present invention does not need to add additional equipment to the terminal, fully utilizes existing resources, consumes little cost, and has great feasibility in practical applications.
