Description
技术领域technical field
本发明涉及通信技术领域，特别涉及一种数据传输的重传监听控制方法、装置及终端。The present invention relates to the field of communication technology, in particular to a retransmission monitoring control method, device and terminal for data transmission.
背景技术Background technique
LTE((Long Term Evolution，长期演进)通信系统具有灵活的数据调度和传输机制，数据传输资源需要基站进行动态分配和授权。如图1所示，在终端没有获得上行传输资源授权的情况下，上行数据传输过程包含四部分：The LTE (Long Term Evolution, Long Term Evolution) communication system has a flexible data scheduling and transmission mechanism, and the data transmission resources need to be dynamically allocated and authorized by the base station. As shown in Figure 1, when the terminal does not obtain the uplink transmission resource authorization, The uplink data transmission process consists of four parts:
1)终端(TX)发送上行调度请求(SR，Schedule Request)，请求基站(RX)分配上行数据传输资源，如子帧2；1) The terminal (TX) sends an uplink scheduling request (SR, Schedule Request) to request the base station (RX) to allocate uplink data transmission resources, such as subframe 2;
2)基站收到终端调度请求后，根据当前资源调度情况，在相应的子帧为终端进行上行授权(UL Grant)，指定终端发送上行数据的资源(指时域和频域位置)和格式(调制方式等)，如子帧8；2) After receiving the terminal scheduling request, the base station performs an uplink grant (UL Grant) for the terminal in the corresponding subframe according to the current resource scheduling situation, and specifies the resource (referring to the time domain and frequency domain position) and the format ( modulation mode, etc.), such as subframe 8;
3)终端收到上行授权后，根据上行授权中指定的资源位置和数据格式，在对应的资源上发送上行数据，如子帧12；3) After receiving the uplink authorization, the terminal sends uplink data on the corresponding resource according to the resource location and data format specified in the uplink authorization, such as subframe 12;
4)终端完成上行数据发送后，需要等待基站侧的反馈，以决定是进行重传还是监听重传调度，如子帧18，当收到基站反馈的ACK时，表明接收成功，不需要重传；4) After the terminal completes the uplink data transmission, it needs to wait for the feedback from the base station side to decide whether to retransmit or monitor the retransmission scheduling. For example, in subframe 18, when receiving the ACK fed back by the base station, it indicates that the reception is successful and no retransmission is required. ;
其中，第4步涉及到上行重传机制。上行重传有同步自适应重传和同步非自适应重传两种方式。“同步”表示重传的子帧位置固定；“非自适应重传”表示重传使用的资源和传输格式和初始传输完全相同，不需要基站发送控制信令指示传输格式和资源，终端接收到基站反馈的NACK(表示未成功接收)后自动触发非自适应重传；“自适应重传”表示重传过程中可以根据实际的信道状态信息改变资源和传输参数，因此每次重传需要基站发送重传调度指示重传的资源和传输格式，终端检测到基站发送的重传调度后触发自适应重传。Among them, the fourth step involves the uplink retransmission mechanism. There are two modes of uplink retransmission: synchronous adaptive retransmission and synchronous non-adaptive retransmission. "Synchronous" means that the subframe position for retransmission is fixed; "Non-adaptive retransmission" means that the resources and transmission format used for retransmission are exactly the same as the initial transmission, and there is no need for the base station to send control signaling to indicate the transmission format and resources. Non-adaptive retransmission is automatically triggered after the NACK fed back by the base station (indicating unsuccessful reception); "adaptive retransmission" means that resources and transmission parameters can be changed according to the actual channel state information during the retransmission process, so each retransmission requires the base station to The retransmission schedule is sent to indicate retransmission resources and transmission formats, and the terminal triggers adaptive retransmission after detecting the retransmission schedule sent by the base station.
如果终端收到NACK或者重传调度，表示基站没有正确接收，终端发起重传。如果终端收到ACK(图1子帧18)，并不表示该上行数据被基站成功接收，基站仍可以在该进程对应的子帧上(图1子帧28、子帧38……)调度自适应重传，终端需在对应的子帧上(图1子帧28、子帧38……)监听重传调度。终端只有收到基站在该进程上调度新数据，或者达到最大监听次数，才表示数据接收成功。如果没有收到基站的新数据调度或者重传调度，终端监听基站调度的次数取决于基站配置的传输次数，重传调度监听位置的总个数＝传输次数-1，传输次数由基站通过空口信令配置给终端。If the terminal receives NACK or retransmission scheduling, it means that the base station did not receive it correctly, and the terminal initiates retransmission. If the terminal receives ACK (subframe 18 in Figure 1), it does not mean that the uplink data has been successfully received by the base station, and the base station can still schedule its own To adapt to retransmission, the terminal needs to monitor retransmission scheduling on corresponding subframes (subframe 28, subframe 38... in FIG. 1). The terminal indicates that the data is received successfully only when it receives the new data scheduled by the base station on this process, or reaches the maximum number of monitoring times. If no new data scheduling or retransmission scheduling from the base station is received, the number of times the terminal monitors the base station scheduling depends on the number of transmissions configured by the base station. Configure the command to the terminal.
该种上行数据传输的反馈机制，目的在于防止终端误检基站反馈的确认消息。如果终端将NACK误检成ACK，则不会发起非自适应重传，基站接收不到预期的重传数据包。按照现有方案，终端仍在相应子帧上监听针对该数据包的重传调度，则基站在发现没有收到预期的重传包后，可以在下一次最接近的监听位置上调度自适应重传，终端收到调度后仍会重传数据包，仅是重传时间后延了若干子帧。反之会导致改上行数据包丢失。The purpose of this feedback mechanism for uplink data transmission is to prevent the terminal from misdetecting the confirmation message fed back by the base station. If the terminal mistakenly detects NACK as ACK, it will not initiate non-adaptive retransmission, and the base station cannot receive expected retransmission data packets. According to the existing scheme, the terminal is still monitoring the retransmission scheduling for the data packet on the corresponding subframe, and the base station can schedule the adaptive retransmission at the next closest monitoring position after finding that the expected retransmission packet is not received , the terminal will still retransmit the data packet after receiving the scheduling, but the retransmission time is delayed by several subframes. On the contrary, the uplink data packet will be lost.
终端在实际工作中可以使用一个或者多个功耗优化方案，如不连续接收(DRX)。在功耗优化方案的设计中，终端可以预先在没有数据传输的时间段上关闭部分收发机组件和模块，工作在低功耗模式，达到节省电量、延长电池工作时间的目的。In actual work, the terminal may use one or more power consumption optimization schemes, such as discontinuous reception (DRX). In the design of the power consumption optimization scheme, the terminal can turn off some transceiver components and modules in advance during the time period when there is no data transmission, and work in a low power consumption mode to save power and prolong the battery working time.
终端根据预先评估的可以工作在低功耗模式的时间间隔长短，关闭一个或者多个组件。某些组件是否可被关闭，取决于低功耗模式时长(设为Tsleep)。比如，终端根据自身组件特性确定一个器件可关闭的最小时间间隔(设为Tmin)。如果终端预估的Tsleep小于Tmin，则没有任何组件可以被关闭，无法达到节省电量的目的。如果Tsleep大于Tmin，达到关闭组件的最小时间门限，则一个或者多个组件可以被关闭。随着Tsleep的增加，可以关闭的组件逐渐增多。当Tsleep达到最大时间门限，大部分组件可以被断电关闭，终端功耗降低到最低水平，进入深度睡眠。综上，终端可工作于低功耗模式的时长决定了可关闭的组件数量，进一步决定了功耗节省效果。The terminal shuts down one or more components according to the pre-evaluated time interval for working in the low power consumption mode. Whether certain components can be turned off depends on the duration of the low power mode (set to Tsleep). For example, the terminal determines the minimum time interval (set as Tmin) during which a device can be turned off according to the characteristics of its own components. If the estimated Tsleep of the terminal is smaller than Tmin, no component can be turned off, and the purpose of saving power cannot be achieved. If Tsleep is greater than Tmin, reaching the minimum time threshold for shutting down components, one or more components may be shut down. With the increase of Tsleep, the components that can be closed gradually increase. When Tsleep reaches the maximum time threshold, most components can be powered off, the terminal power consumption is reduced to the lowest level, and it enters deep sleep. To sum up, the duration that the terminal can work in the low-power mode determines the number of components that can be turned off, and further determines the power saving effect.
在现有上行数据传输方案中，如图2所示，监听重传调度将会反复中断休眠周期，将一段较长的Tsleep切断为多段较短的休眠时间，导致DRX带来的节省增益非常小。并且开/关组件本身就带来一些额外的准备工作，终端从休眠状态醒过来监听重传调度的子帧的前后几个子帧就处于工作状态，导致终端工作于低功耗模式的时长可能接近于零。In the existing uplink data transmission scheme, as shown in Figure 2, the monitoring and retransmission scheduling will repeatedly interrupt the sleep period, cutting a long Tsleep into multiple short sleep periods, resulting in very little saving gain brought by DRX . And the on/off component itself brings some additional preparation work. The terminal wakes up from the dormant state and monitors the subframes of the retransmission scheduling before and after the subframes are in the working state, resulting in the terminal working in the low power mode. The duration may be close to at zero.

具体实施方式Detailed ways
为使本发明的目的、技术方案和优点更加清楚，下面将结合附图及具体实施例对本发明进行详细描述。In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.
本发明针对现有的终端在上传数据时，因约定的重传调度监听位置的总个数相同，在数据传输过程中是否发生重传调度都需要在相同的位置进行监听，此种监听方式，会重复唤醒终端上的组件，导致终端功耗较大，耗电较多的问题，提供一种数据传输的重传监听控制方法、装置及终端。The present invention aims at the existing terminal when uploading data, because the total number of agreed retransmission scheduling monitoring positions is the same, whether retransmission scheduling occurs during the data transmission process needs to be monitored at the same position, this monitoring method, The components on the terminal will be woken up repeatedly, resulting in high power consumption of the terminal and the problem of high power consumption. A retransmission monitoring control method, device and terminal for data transmission are provided.
如图3所示，本发明实施例提供一种数据传输的重传监听控制方法，应用于一终端，包括：As shown in FIG. 3, an embodiment of the present invention provides a retransmission monitoring control method for data transmission, which is applied to a terminal and includes:
步骤110，向基站发送上行数据时，获取预设的重传调度监听位置的总个数以及数据传输开始的第一个评估时间的预设评估时长和重传调度监听位置的总个数的预设第一调整步长；Step 110, when sending uplink data to the base station, obtain the preset total number of retransmission scheduling monitoring positions, the preset evaluation duration of the first evaluation time at the start of data transmission, and the preset total number of retransmission scheduling monitoring positions. Set the first adjustment step;
步骤120，在第一个评估时间内，根据预设的重传调度监听位置的总个数，获取每个监听位置上的重传调度次数的监听结果；Step 120, within the first evaluation time, according to the preset total number of retransmission scheduling monitoring positions, obtain the monitoring result of the number of times of retransmission scheduling at each monitoring position;
步骤130，根据所述监听结果以及所述重传调度监听位置的总个数的预设第一调整步长，调整重传调度监听位置的总个数，使得在接下来的第二个评估时间内，按照调整后的重传调度监听位置的总个数控制数据传输的重传监听。Step 130, adjust the total number of retransmission scheduling monitoring positions according to the monitoring result and the preset first adjustment step size of the total number of retransmission scheduling monitoring positions, so that at the next second evaluation time Inside, the retransmission monitoring of data transmission is controlled according to the adjusted total number of retransmission scheduling monitoring positions.
上述方案，在一次数据传输过程中，通过将整个数据传输过程分为多个时间段，在每个时间段中分别对数据的重传调度进行监听，以此调整下个时间段内的重传调度监听位置的总个数，通过此种方式，实时调整终端在数据传输过程中重传调度监听位置的总个数，在数据传输过程中，发生较少重传调度时，降低重传调度监听位置的总个数；以此减少了终端因为需要监听重传调度而从休眠期被唤醒的次数，延长了终端低功耗工作时长，降低了终端的功耗。In the above solution, during a data transmission process, the entire data transmission process is divided into multiple time periods, and the data retransmission schedule is monitored in each time period, so as to adjust the retransmission in the next time period The total number of scheduling monitoring positions. In this way, the total number of retransmission scheduling monitoring positions of the terminal during data transmission is adjusted in real time. During data transmission, when less retransmission scheduling occurs, the retransmission scheduling monitoring is reduced. The total number of locations; this reduces the number of times the terminal is woken up from the dormant period because it needs to monitor the retransmission scheduling, prolongs the working time of the terminal with low power consumption, and reduces the power consumption of the terminal.
上述实施例的所述步骤110中，在一次数据传输开始时，所述预设的重传调度监听位置的总个数的初始值可以由基站统一配置为最大值Nmax，其中，Nmax＝传输次数-1；也可以由终端根据当前的信道传输质量来确定，例如，当信道传输质量较好时，设置的初始值相对较小，反之，设置的初始值应相对较大。在数据传输开始时，第一个评估时间内的评估时长和预设第一调整步长可以选用初始设置值，也可以在数据传输开始前，根据信道传输质量选用较为适宜的初始值。In the step 110 of the above-mentioned embodiment, at the beginning of a data transmission, the initial value of the total number of preset retransmission scheduling monitoring positions can be uniformly configured by the base station as a maximum value Nmax, where Nmax=number of transmissions -1; can also be determined by the terminal according to the current channel transmission quality, for example, when the channel transmission quality is good, the initial value set is relatively small, otherwise, the initial value should be relatively large. At the beginning of data transmission, the evaluation duration and the preset first adjustment step in the first evaluation time can be selected as initial setting values, or a more appropriate initial value can be selected according to the channel transmission quality before the data transmission starts.
应当说明的是，在一次数据传输过程中，终端会按照基站规定的数据大小，将长度较大的数据进行分割，形成多个具有较小长度的数据片进行传送，在每个数据片传送的过程中，均需要获取基站的授权后才可以进行数据片的传输；这里可以认为一个数据片在一个时间帧内便可传输完成，进一步如图1所示，即在时间帧12的时刻，数据片传输完成，其余的时间便是对此数据片是否接收成功的重传调度的监听，在没有传输成功时，进行重传；上述实施例中，在所述第一评估时间内可能包含多个数据片的传输过程，对每个数据片在传输过程中监听重传调度的位置是相同的。It should be noted that during a data transmission process, the terminal will divide the data with a larger length according to the data size specified by the base station to form multiple data pieces with a smaller length for transmission. During the process, it is necessary to obtain the authorization of the base station before the data slice can be transmitted; here it can be considered that a data slice can be transmitted within a time frame, further shown in Figure 1, that is, at the moment of time frame 12, the data The slice transmission is completed, and the rest of the time is to monitor whether the data slice is successfully received by the retransmission schedule, and retransmit when the transmission is not successful; The transmission process of the data slice is the same for each data slice during the transmission process to monitor the retransmission scheduling position.
基于上述叙述，本发明步骤120的具体实现方式为：Based on the above narration, the specific implementation of step 120 of the present invention is:
记录每个监听位置上发生重传调度的次数；Record the number of times retransmission scheduling occurs at each listening position;
所述监听结果由监听位置以及每个监听位置上对应的重传调度次数共同构成。The monitoring result is composed of monitoring positions and corresponding retransmission scheduling times at each monitoring position.
应当说明的是，如图1可知，每个数据片在传输过程中，均会在本数据片的时间帧28和时间帧38的位置上进行监听，因此步骤120中统计的便是第一个评估时间内所有数据片在时间帧28的位置发生重传调度的总次数，以及在时间帧38的位置发生重传调度的总次数。It should be noted that, as shown in Figure 1, each data piece will be monitored at the time frame 28 and time frame 38 of the data piece during the transmission process, so the statistics in step 120 are the first The total number of retransmission scheduling occurrences at the position of time frame 28 and the total number of retransmission scheduling occurrences at the position of time frame 38 of all data slices within the evaluation time.
在得到每个监听位置上的重传调度次数的监听结果后，便可以对重传调度监听位置的总个数进行调整，以使得在下一个评估时间内按照调整后的重传调度监听位置的总个数进行数据的重传监听。因此，本发明实施例的所述步骤130的具体实现方式为：After obtaining the monitoring result of the retransmission scheduling times at each monitoring position, the total number of retransmission scheduling monitoring positions can be adjusted so that the total number of retransmission scheduling monitoring positions can be adjusted according to the adjusted retransmission scheduling monitoring position in the next evaluation time. The number of data retransmission monitoring. Therefore, the specific implementation manner of the step 130 in the embodiment of the present invention is as follows:
当所述监听结果表明存在预设的监听位置的重传调度次数为零，则根据所述预设第一调整步长，在预设的重传调度监听位置的总个数的基础上，减少重传调度监听位置的总个数，使得调整后的重传调度监听位置的总个数不小于1；When the monitoring result shows that the number of retransmission scheduling of the preset monitoring position is zero, then according to the preset first adjustment step size, on the basis of the total number of preset retransmission scheduling monitoring positions, reduce The total number of retransmission scheduling monitoring positions, so that the adjusted total number of retransmission scheduling monitoring positions is not less than 1;
当所述监听结果表明预设的所有监听位置的重传调度次数均不为零，则根据所述预设第一调整步长，在预设的重传调度监听位置的总个数的基础上，增加重传调度监听位置的总个数，使得增加后的重传调度监听位置的总个数不超过预设最大重传调度监听位置总个数。When the monitoring result shows that the preset retransmission scheduling times of all monitoring positions are not zero, then according to the preset first adjustment step size, on the basis of the total number of preset retransmission scheduling monitoring positions , increase the total number of retransmission scheduling monitoring positions, so that the increased total number of retransmission scheduling monitoring positions does not exceed the preset maximum total number of retransmission scheduling monitoring positions.
应当说明的是，一般数据在传输过程中，时间帧越往后，发生重传调度的机率会越大，因此在进行调整时，在重传调度监听位置的总个数不为1的情况下，当统计结果表明所述监听结果中包含在相同的监听位置上发生重传调度的次数为零的情况，则需要减少数据传输的重传监听，在进行减少时，会优先去除排在最后面的监听位置，即停用最后的某一个或几个监听位置；在重传调度监听位置的总个数不为最大值的情况下，当统计结果表明所述监听结果中包含在所有的监听位置上发生重传调度的次数均不为零的情况，则在进行增加时，会在原有的监听位置的最后增加相应的监听位置，即启用最后的某一个或几个监听位置。It should be noted that during the general data transmission process, the later the time frame is, the greater the probability of retransmission scheduling will be. Therefore, when making adjustments, when the total number of retransmission scheduling monitoring positions is not 1 , when the statistical results show that the number of retransmission scheduling occurrences at the same monitoring position is zero in the monitoring results, it is necessary to reduce the retransmission monitoring of data transmission. When reducing, it will preferentially remove the last monitoring positions, that is, deactivate the last one or several monitoring positions; in the case that the total number of retransmission scheduling monitoring positions is not the maximum value, when the statistical results show that the monitoring results include all monitoring positions If the number of times of retransmission scheduling on the network is not zero, when increasing, the corresponding monitoring position will be added at the end of the original monitoring position, that is, the last one or several monitoring positions will be enabled.
例如，数据传输中配置的最大重传调度监听位置的总个数为10个，即位置1、位置2……位置10，在数据传输开始时，获取到信道传输质量较好，只启用位置1至位置4的监听即可，在第一个评估时间内，经过统计发现位置1至位置4的监听位置上均有重传调度发生，此时，表明此监听位置的个数选取是不合理的，需要增加监听位置的个数，按照预设第一调整步长，增加监听位置，比如，当预设第一调整步长为2时，此时需要增加两个监听位置，即在位置4后启用位置5和位置6这两个监听位置。For example, the total number of maximum retransmission scheduling monitoring positions configured in data transmission is 10, that is, position 1, position 2...position 10. At the beginning of data transmission, the channel transmission quality is obtained, and only position 1 is enabled. The monitoring at position 4 is enough. In the first evaluation time, it is found that retransmission scheduling occurs at the monitoring positions from position 1 to position 4 through statistics. At this time, it shows that the selection of the number of monitoring positions is unreasonable. , it is necessary to increase the number of monitoring positions, and increase the monitoring position according to the preset first adjustment step. For example, when the preset first adjustment step is 2, two monitoring positions need to be added at this time, that is, after position 4 The two listening positions, position 5 and position 6, are enabled.
上述的实现方式可以为：The above implementation can be as follows:
1、当Nmax≥N＞1且∑Ri＝0(i为整数，i＝N，N-1，N-2…N-k+1，Δn≥k≥1)，则N＝max{N-k，1}，保证至少有一次监听重传调度的机会；1. When Nmax≥N>1 and ∑Ri=0 (i is an integer, i=N, N-1, N-2...N-k+1, Δn≥k≥1), then N=max{N-k, 1}, to ensure at least one chance to monitor retransmission scheduling;
2、当Nmax>N≥1且RN>0(即重传调度发生在最后一次机会上)，则N＝min{N+Δn，Nmax}；2. When Nmax>N≥1 and R N >0 (that is, retransmission scheduling occurs on the last chance), then N=min{N+Δn, Nmax};
3、其它情况N保持不变；3. In other cases, N remains unchanged;
其中，N为当前的监听重传调度的总个数，Nmax为重传调度监听位置的总个数的最大值，Δn为预设第一调整步长。Wherein, N is the total number of the current monitoring retransmission scheduling, Nmax is the maximum value of the total number of retransmission scheduling monitoring positions, and Δn is the preset first adjustment step size.
在第一个评估时间内，得到调整后的重传调度监听位置的总个数，在第二个评估时间内进行重传调度监听位置的总个数的调整时，首先要获取的第二个评估时间的评估时长以及第二调整步长，在考虑到不增加终端的功耗的情况下，可以在第二个评估时间内沿用第一个评估时间的评估时长和第一调整步长，但是，为了在信道条件较好时重传监听位置的个数能够高频快速收敛到目标值，可以使用幅度较大的快速调整，评估时长取较小值，调整步长取较大值；在信道条件较差时重传监听次数的收敛可能是低频慢速的，评估时长取较大值，调整步长取较小值。In the first evaluation time, the total number of adjusted retransmission scheduling monitoring positions is obtained. When adjusting the total number of retransmission scheduling monitoring positions in the second evaluation time, the second The evaluation duration and the second adjustment step of the evaluation time, in consideration of not increasing the power consumption of the terminal, the evaluation duration and the first adjustment step of the first evaluation time can be used in the second evaluation time, but , in order that the number of retransmission monitoring positions can quickly converge to the target value at high frequency when the channel condition is good, a fast adjustment with a large range can be used, and the evaluation time is taken as a small value, and the adjustment step is taken as a large value; in the channel When the conditions are poor, the convergence of the number of retransmission monitoring times may be low-frequency and slow. The evaluation time is taken as a larger value, and the adjustment step is taken as a smaller value.
因此，本发明另一实施例中，在步骤130之后还包括：Therefore, in another embodiment of the present invention, after step 130, it also includes:
获取当前的信道传输质量的评估参数；Obtain the evaluation parameters of the current channel transmission quality;
根据所述评估参数，在所述评估参数对照表中获取第二评估时间对应的预设评估时长；Obtain a preset evaluation duration corresponding to the second evaluation time in the evaluation parameter comparison table according to the evaluation parameters;

应当说明的是，本发明实施例中，所述评估参数优选为接收信号强度(RSRP)和信噪比(SINR)。It should be noted that, in the embodiment of the present invention, the evaluation parameters are preferably received signal strength (RSRP) and signal-to-noise ratio (SINR).
上述方案中，设置多个表征信道条件的门限值，相对应地设置多个不同的评估时长和调整步长，不同门限值范围内选择不同的评估时长和调整步长。在信道条件落入某门限值范围内时，选择相应的评估时长和调整步长。依据信道传输质量进行相应评估时长和调整步长的选取，可以较快速的将重传调度监听位置的总个数调整到合适的取值，以此保证终端上的组件能快速达到稳定工作的状态。In the above solution, multiple thresholds representing channel conditions are set, and multiple different evaluation time lengths and adjustment step sizes are set correspondingly, and different evaluation time lengths and adjustment step sizes are selected within different threshold value ranges. When the channel condition falls within a certain threshold range, a corresponding evaluation time length and adjustment step size are selected. According to the selection of the corresponding evaluation time and adjustment step according to the channel transmission quality, the total number of retransmission scheduling monitoring positions can be adjusted to an appropriate value quickly, so as to ensure that the components on the terminal can quickly reach a stable working state .
如图4所示，本发明所述重传监听控制方法的详细流程为：As shown in Figure 4, the detailed flow of the retransmission monitoring control method of the present invention is as follows:
在数据传输开始时，设置初始的重传调度监听位置的总个数(优选为网络配置的最大值，以使得终端和基站在传输开始时保持一致)，然后确定首次调整的评估时长和调整步长；在第一个评估时间的评估时长内，记录当前信道传输条件下，重传调度发生的位置以及每个位置上的重传调度的次数，例如：发生在位置1的重传调度次数为R1，发生在位置2的重传调度次数为R2……发生在位置n的重传调度次数为Rn；根据记录的重传调度发生的位置以及每个位置上的重传调度的次数，依据调整步长调整重传调度监听位置的总个数；然后获取下一个评估时间的评估时长及调整步长，在下一个评估时间内重新进行重传调度监听位置的总个数的调整，直到完成本次数据传输。At the beginning of data transmission, set the total number of initial retransmission scheduling monitoring positions (preferably the maximum value configured by the network, so that the terminal and the base station are consistent at the beginning of transmission), and then determine the evaluation duration and adjustment step for the first adjustment Long; within the evaluation duration of the first evaluation time, record the location where retransmission scheduling occurs and the number of retransmission scheduling at each location under the current channel transmission conditions, for example: the number of retransmission scheduling that occurs at location 1 is R1, the number of retransmission scheduling at position 2 is R2...the number of retransmission scheduling at position n is Rn; according to the location where the recorded retransmission scheduling occurs and the number of retransmission scheduling at each position, adjust according to The step size adjusts the total number of retransmission scheduling monitoring positions; then obtains the evaluation duration and adjustment step of the next evaluation time, and re-adjusts the total number of retransmission scheduling monitoring positions in the next evaluation time until the completion of this time data transmission.
