Description
技术领域 technical field
本发明涉及移动通信技术，尤其涉及一种载波聚合系统中的调度方法、系统和设备。The present invention relates to mobile communication technology, in particular to a scheduling method, system and equipment in a carrier aggregation system.
背景技术 Background technique
目前的载波聚合系统，主要考虑了三种载波聚合场景，一种是同一频段内的连续载波聚合，一种是同一频段内的非连续载波聚合，一种是不同频段间的非连续载波聚合。The current carrier aggregation system mainly considers three carrier aggregation scenarios, one is continuous carrier aggregation in the same frequency band, the other is non-continuous carrier aggregation in the same frequency band, and the other is non-continuous carrier aggregation between different frequency bands.
图1是目前三种载波聚合场景中各载波占用的频段示意图。Fig. 1 is a schematic diagram of frequency bands occupied by each carrier in the current three carrier aggregation scenarios.
在同一频段内的连续载波聚合和非连续载波聚合中，各个载波上的上下行时隙配置应该相同，否则将出现严重的基站间干扰以及终端间干扰。对于不同频段间的非连续载波聚合，不同频段的不同载波上的上下行时隙配置可能不同，以便更加灵活地适应网络的上下行业务速率要求。当各个载波的上行行时隙配置不同时，如何解决基站间的相互干扰以及终端间的相互干扰成为必须解决的技术问题。In continuous carrier aggregation and non-continuous carrier aggregation in the same frequency band, the configuration of uplink and downlink time slots on each carrier should be the same, otherwise serious interference between base stations and terminals will occur. For discontinuous carrier aggregation between different frequency bands, the uplink and downlink time slot configurations on different carriers in different frequency bands may be different, so as to more flexibly adapt to the network uplink and downlink service rate requirements. When the uplink time slots of each carrier are configured differently, how to solve the mutual interference between base stations and the mutual interference between terminals becomes a technical problem that must be solved.
对于不同频段间的非连续载波聚合系统，目前有方案提出通过射频滤波来解决基站间的干扰以及终端间的干扰，从而实现基站之间的共存以及终端之间的共存。For the non-continuous carrier aggregation system between different frequency bands, there are currently solutions to solve the interference between base stations and terminals through radio frequency filtering, so as to realize the coexistence between base stations and terminals.
对于基站之间的共存，假设以接收机灵敏度损失0.8dB作为评估标准的话，A频段内的基站发射机保护B频段内的接收机，所需衰减为74dB(基站带宽20MHz，发射功率46dBm，接收机噪声系数5dB，邻频泄露比为45dB，接收机噪声功率为-109dBm/MHz，天线间最小耦合损耗为30dB，所需衰减为46-13-109-7-45-30＝74dB)。若A、B频段之间的频率间隔足够远的话，采用成本较高的介质滤波器的话，将有可能达到所需衰减要求，但是成本较高。For the coexistence between base stations, assuming that the receiver sensitivity loss is 0.8dB as the evaluation standard, the base station transmitter in the A frequency band protects the receiver in the B frequency band, and the required attenuation is 74dB (the base station bandwidth is 20MHz, the transmission power is 46dBm, and the receiver The machine noise figure is 5dB, the adjacent frequency leakage ratio is 45dB, the receiver noise power is -109dBm/MHz, the minimum coupling loss between antennas is 30dB, and the required attenuation is 46-13-109-7-45-30＝74dB). If the frequency interval between the A and B frequency bands is far enough, it is possible to meet the required attenuation requirements by using a high-cost dielectric filter, but the cost is high.
对于终端来讲，假设以接收机灵敏度损失3dB作为评估准则，所需衰减为73dB(带宽20MHz，发射功率23dBm，接收机噪声系数9dB，邻频泄露比为30dB，终端天线两根天线间最小耦合损耗为12dB，则所需衰减为23-13-(-174+60+9)-30-12＝73dB)，这对于终端是不可实现的，因为采用常用的SAW滤波器，终端侧带外20MHz外的衰减只有30-40dB左右，无法达到终端间共存所需的要求。For the terminal, assuming that the receiver sensitivity loss is 3dB as the evaluation criterion, the required attenuation is 73dB (the bandwidth is 20MHz, the transmit power is 23dBm, the receiver noise figure is 9dB, the adjacent frequency leakage ratio is 30dB, and the minimum coupling between the two antennas of the terminal antenna is If the loss is 12dB, the required attenuation is 23-13-(-174+60+9)-30-12=73dB), which is unrealizable for the terminal, because the commonly used SAW filter is used, and the terminal side is out-of-band 20MHz The external attenuation is only about 30-40dB, which cannot meet the requirements for coexistence between terminals.
可见，对于上述三种载波聚合系统，如何解决终端侧不同载波间的干扰问题，仍是当前需要解决的技术问题。It can be seen that for the above three carrier aggregation systems, how to solve the interference problem between different carriers at the terminal side is still a technical problem to be solved at present.

In addition, for the system, the primary and secondary carrier configurations of different terminals can be different, that is, the primary carrier of one terminal can be configured as the secondary carrier of another terminal, so the scheduling of secondary carriers on a specific terminal does not affect the system The overall throughput (restricted secondary carrier resources can be scheduled to other terminals), so as to ensure system performance while reducing inter-carrier interference.

具体实施方式 Detailed ways
本发明提出，在载波聚合系统中，为每个终端配置主载波(Primarycell，Pcell)和辅载波(Secondarycell，Scell)，其中Pcell一般为1个，Scell可以为若干个，重要的控制信息在Pcell上传输，由于Pcell上传输的信息较为重要，因此以保证Pcell上的传输质量为主，当终端在当前调度时刻的主辅载波上的时隙方向不同时，网络侧设备根据终端的Pcell的调度情况，确定Scell的调度，避免终端在辅载波上的发射干扰在主载波上的接收，或者避免主载波上的发射干扰辅载波上的接收。The present invention proposes that in the carrier aggregation system, a primary carrier (Primary cell, Pcell) and a secondary carrier (Secondary cell, Scell) are configured for each terminal, where there is generally one Pcell, and there may be several Scells, and important control information is stored in the Pcell Uplink transmission, because the information transmitted on Pcell is more important, so it is mainly to ensure the transmission quality on Pcell. When the direction of the time slot on the primary and secondary carriers of the terminal at the current scheduling time is different, the network side device will schedule according to the Pcell of the terminal In this case, the scheduling of the Scell is determined to prevent the transmission of the terminal on the secondary carrier from interfering with the reception on the main carrier, or prevent the transmission on the main carrier from interfering with the reception on the secondary carrier.
在载波聚合系统中，对于一个终端来说，系统会为其配置一个主载波和若干个辅载波，并且，不同终端的Pcell和/或Scell的配置可以相同也可以不同，例如可以将一终端的主载波配置为另外一终端的辅载波。因此，虽然对于特定终端，其在Scell上的调度是受限制的，但对于网络来看，由于Pcell和Scell都是由网络侧进行配置的，一个UE的Scell可能是另外一个UE的Pcell，所以整体的系统容量是不会受到影响的，这样既支持了不同载波上的不同时隙配比，又不会影响系统容量。通过在不同频段配置不同的上下行时隙比例，可以更加合理的利用网络资源适应不同的上下行业务需求。In the carrier aggregation system, for a terminal, the system configures a primary carrier and several secondary carriers, and the configurations of Pcell and/or Scell of different terminals can be the same or different, for example, a terminal's The primary carrier is configured as a secondary carrier of another terminal. Therefore, although for a specific terminal, its scheduling on the Scell is limited, from the perspective of the network, since both Pcell and Scell are configured by the network side, the Scell of one UE may be the Pcell of another UE, so The overall system capacity will not be affected, thus not only supporting different time slot ratios on different carriers, but also not affecting the system capacity. By configuring different ratios of uplink and downlink time slots in different frequency bands, network resources can be more reasonably utilized to meet different uplink and downlink service requirements.
图2是本发明提供的载波聚合系统中的调度方法流程图。Fig. 2 is a flowchart of a scheduling method in the carrier aggregation system provided by the present invention.
如图2所示，该方法包括：As shown in Figure 2, the method includes:
步骤201，网络侧设备判断在调度周期内终端的主载波是否被调度，如果是，执行步骤202，否则执行步骤205。Step 201 , the network side device judges whether the main carrier of the terminal is scheduled within the scheduling period, if yes, executes step 202 , otherwise executes step 205 .
本步骤中的调度周期可以是当前时刻对应的调度周期，也可以是当前时刻之后的某个调度周期。The scheduling cycle in this step may be the scheduling cycle corresponding to the current moment, or a certain scheduling cycle after the current moment.
步骤202，判断对该主载波的调度是上行调度还是下行调度，如果是上行调度，执行步骤203，如果是下行调度，执行步骤204。Step 202, judge whether the scheduling of the main carrier is uplink scheduling or downlink scheduling, if it is uplink scheduling, perform step 203, if it is downlink scheduling, perform step 204.
步骤203，在同一调度周期内禁止对该终端的辅载波进行下行调度，结束本流程。Step 203, prohibit downlink scheduling of the secondary carrier of the terminal within the same scheduling period, and end this process.
步骤204，在同一调度周期内禁止对该终端的主载波进行上行调度，结束本流程。Step 204, prohibit uplink scheduling of the main carrier of the terminal within the same scheduling period, and end this process.
步骤205，在同一调度周期内对该终端的辅载波进行正常调度，即进行上行调度和/或下行调度，结束本流程。Step 205: Perform normal scheduling on the secondary carrier of the terminal in the same scheduling period, that is, perform uplink scheduling and/or downlink scheduling, and end this process.
当终端配置有一个主载波和多个辅载波时，仍然以主载波为中心，所有辅载波均采用图2所示方法进行调度，即如果在调度周期内对主载波进行上行调度，则禁止在同一调度周期内对该终端的任意辅载波进行下行调度，如果在调度周期内对主载波进行下行调度，则禁止在同一调度周期内对该终端的任意辅载波进行上行调度。When the terminal is configured with a primary carrier and multiple secondary carriers, the primary carrier is still the center, and all secondary carriers are scheduled using the method shown in Figure 2, that is, if the primary carrier is scheduled uplink within the scheduling period, it is prohibited Perform downlink scheduling on any secondary carrier of the terminal in the same scheduling period, and prohibit uplink scheduling on any secondary carrier of the terminal in the same scheduling period if downlink scheduling is performed on the primary carrier in the same scheduling period.
此外，若未来终端滤波器技术发生飞跃，或者载波聚合的载波间隔足够远，可以满足终端同时在多个载波上进行方向相反的信息传输，即在主载波进行接收的同时，在辅载波上进行发射，或者在主载波进行发射的同时，在辅载波上进行接收，可以增加指示信息或载波聚合能力信息，由终端向网络侧发送所述指示信息和/或所述载波聚合能力信息，告知网络侧该终端具备同时在某些频段上进行方向相反的信息传输的能力，网络侧可以依据该能力指示信息和/或载波聚合能力信息进行调度，具体流程参见图3。In addition, if there is a leap in terminal filter technology in the future, or if the carrier aggregation carrier spacing is far enough, the terminal can simultaneously transmit information in opposite directions on multiple carriers, that is, while the main carrier is receiving, it will be transmitted on the secondary carrier. transmit, or receive on the secondary carrier while transmitting on the primary carrier, may add indication information or carrier aggregation capability information, and the terminal sends the indication information and/or the carrier aggregation capability information to the network side to inform the network On the side, the terminal has the ability to transmit information in opposite directions on certain frequency bands at the same time, and the network side can perform scheduling based on the capability indication information and/or carrier aggregation capability information. See Figure 3 for the specific process.
图3是本发明提供的载波聚合系统中的又一调度方法流程图。Fig. 3 is a flowchart of another scheduling method in the carrier aggregation system provided by the present invention.
如图3所示，该方法包括：As shown in Figure 3, the method includes:
步骤301，网络侧设备判断终端是否支持主辅载波同时收发，即同时在主辅载波上进行方向相反的信息传输，如果是，执行步骤306，否则执行步骤302。In step 301, the network-side device judges whether the terminal supports simultaneous transmission and reception of the main and auxiliary carriers, that is, information transmission in opposite directions on the main and auxiliary carriers at the same time, and if yes, executes step 306; otherwise, executes step 302.
本步骤中，网络侧设备接收终端上报的指示信息和/或载波聚合能力信息，根据终端上报的指示信息和/或载波聚合能力信息判断该终端是否支持同时在配置的主载波和辅载波上进行方向相反的信息传输。In this step, the network-side device receives the indication information and/or carrier aggregation capability information reported by the terminal, and judges whether the terminal supports concurrently configured primary carrier and secondary carrier based on the indication information and/or carrier aggregation capability information reported by the terminal. information transfer in the opposite direction.
步骤302，网络侧设备判断在调度周期内终端的主载波是否被调度，如果是，执行步骤303，否则执行步骤306。Step 302, the network side device judges whether the main carrier of the terminal is scheduled within the scheduling period, if yes, executes step 303, otherwise executes step 306.
本步骤中的调度周期可以是当前时刻对应的调度周期，也可以是当前时刻之后的某个调度周期。The scheduling cycle in this step may be the scheduling cycle corresponding to the current moment, or a certain scheduling cycle after the current moment.
步骤303，判断对该主载波的调度是上行调度还是下行调度，如果是上行调度，执行步骤304，如果是下行调度，执行步骤305。Step 303, judge whether the scheduling of the main carrier is uplink scheduling or downlink scheduling, if it is uplink scheduling, perform step 304, if it is downlink scheduling, perform step 305.

下面举一个具体的例子对本发明进行示例性说明，具体请参见图4。A specific example is given below to illustrate the present invention, please refer to FIG. 4 for details.
图4是本发明提供的载波聚合系统中的调度示意图。Fig. 4 is a schematic diagram of scheduling in the carrier aggregation system provided by the present invention.
如图4所示，网络侧为UE1配置频段1上的载波1(CC1)为Pcell，频段2上的载波2(CC2)为Scell，为UE2配置CC1为Scell，CC2为Pcell。在时间轴上，CC1和CC2的上下行时隙比例分别被配置为3∶2和2∶3。As shown in Figure 4, the network side configures UE1 with carrier 1 (CC1) on frequency band 1 as a Pcell, carrier 2 (CC2) on frequency band 2 as a Scell, and configures UE2 with CC1 as a Scell and CC2 as a Pcell. On the time axis, the uplink and downlink time slot ratios of CC1 and CC2 are respectively configured as 3:2 and 2:3.
网络侧在第三个子帧上两个载波的时隙方向不同，则在该子帧上，对于UE1来说，其Pcell是CC1，为上行发送，Scell为CC2，为下行接收，如果同时调度，UE1的CC1上的发射将干扰CC2上的数据接收；对于UE2来说，其Pcell是CC2，为下行发送，Scell为CC1，为上行接收，如果同时调度，UE2的CC1上的发射将干扰CC2上的数据接收；则根据本发明：On the network side, on the third subframe, the time slot directions of the two carriers are different. In this subframe, for UE1, its Pcell is CC1, which is for uplink transmission, and the Scell is CC2, which is for downlink reception. If they are scheduled at the same time, The transmission on CC1 of UE1 will interfere with the data reception on CC2; for UE2, its Pcell is CC2, which is for downlink transmission, and its Scell is CC1, which is for uplink reception. If scheduled at the same time, the transmission on UE2's CC1 will interfere with CC2 The data reception; then according to the present invention:
网络侧根据UE1的Pcell上的调度情况，确定Scell上的调度。具体地：The network side determines the scheduling on the Scell according to the scheduling situation on the Pcell of UE1. specifically:
若网络侧在Pcell上为UE1调度了资源(上行发射)，则在Scell的该子帧上不再为UE1调度资源(下行接收)。If the network side schedules resources for UE1 on the Pcell (uplink transmission), then no longer schedules resources for UE1 on the subframe of the Scell (downlink reception).
若网络侧在Pcell上没有为UE1调度资源，则在Scell上该子帧上可以为UE1调度资源。If the network side does not schedule resources for UE1 on the Pcell, it may schedule resources for UE1 on the subframe on the Scell.
同样的，网络侧根据UE2的Pcell上的调度情况，确定Scell上的调度。具体地：Similarly, the network side determines the scheduling on the Scell according to the scheduling situation on the Pcell of UE2. specifically:
若网络侧在Pcell上为UE2调度了资源(下行接收)，则在Scell的该子帧上不再为UE1调度资源(上行发射)。If the network side schedules resources for UE2 on the Pcell (downlink reception), then no longer schedules resources for UE1 on the subframe of the Scell (uplink transmission).
若网络侧在Pcell上没有为UE1调度资源，则在Scell上该子帧上可以为UE1调度资源。If the network side does not schedule resources for UE1 on the Pcell, it may schedule resources for UE1 on the subframe on the Scell.
对于子帧1、2、4和5来说，可采用相同方法配置辅载波的调度情况。For subframes 1, 2, 4 and 5, the same method can be used to configure the scheduling of the secondary carrier.
由图4可见，对于某个终端，根据其Pcell的调度情况，确定其Scell上的调度配置，可以解决终端一个载波发射干扰另外载波接收的问题，支持不同载波配置不同的上下行时隙比例的功能。It can be seen from Figure 4 that for a certain terminal, according to the scheduling situation of its Pcell, the scheduling configuration on its Scell is determined, which can solve the problem that one carrier of the terminal transmits and interferes with the reception of another carrier, and supports the configuration of different carrier configurations with different uplink and downlink time slot ratios. Function.
本发明中，不同载波上的上下行时隙比例配置信息和各个终端的Pcell和Scell配置情况都是网络侧设备可以获知的，因此本发明的可实现性较强，并且本发明不需要改动现有协议即可支持不同载波上配置不同时隙比例，适应网络上下行流量特性，实现简单，应用前景较高。In the present invention, the ratio configuration information of uplink and downlink time slots on different carriers and the Pcell and Scell configuration of each terminal can be known by the network side equipment, so the present invention has strong realizability, and the present invention does not need to change the existing There is a protocol to support the configuration of different time slot ratios on different carriers, adapting to the characteristics of uplink and downlink traffic on the network, easy to implement, and has a high application prospect.
