Description

一种时隙调度方法及终端、存储介质Time slot scheduling method, terminal and storage medium 技术领域Technical field
本申请涉及通信领域,尤其涉及一种时隙调度方法及终端、存储介质。The present application relates to the field of communications, and in particular, to a time slot scheduling method, terminal, and storage medium.
背景技术Background technique
随着第五代移动通信技术(5G,5th-Generation)的快速发展,终端能够同时支持长期演进(LTE,Long Term Evolution)和新空口(NR,New Radio)两种制式,并处于同时工作状态,对终端的数据传输方式的改进能够提高终端的数据传输速度和质量,然而,在数据传输速度和质量提升的同时,也会提高终端的功率,高功率终端产生大量辐射被人的脑部吸收,会大大影响人体健康。为了保证终端在安全标准内,标准上对电磁波吸收比值(SAR,Specific Absorption Rate)有严格的指标要求,SAR值是衡量终端对人体电磁辐射强度的指标参量,标准规定终端的SAR值必须低于限定的SAR值。With the rapid development of 5th-generation mobile communication technology (5G, 5th-Generation), the terminal can support both Long Term Evolution (LTE) and New Radio (NR) standards, and work simultaneously. The improvement of the data transmission method of the terminal can improve the data transmission speed and quality of the terminal. However, while the data transmission speed and quality are improved, the power of the terminal will also be increased. A large amount of radiation generated by high-power terminals is absorbed by the human brain. Will greatly affect human health. In order to ensure that the terminal is in the safety standard, the standard has strict index requirements for electromagnetic wave absorption ratio (SAR). The SAR value is an index parameter that measures the intensity of the human body's electromagnetic radiation. The standard stipulates that the terminal's SAR value must be lower than Limited SAR value.
现阶段降低终端的SAR值的方式包括:天线结构中增加分集天线,分集天线的接收频点与主天线SAR峰值对应的频点相匹配,通过分集天线分散主天线SAR峰值对应频点的电流分布,从而降低主天线的SAR峰值;或者设置多个天线,并从多个天线中,选用最大射频功率对应的SAR值未超过预设SAR阈值的天线中的一个天线作为该终端的主天线等更改终端硬件结构的方式。以及通过降低终端发送信号时的发射功率来降低终端的SAR值。At this stage, the method of reducing the SAR value of the terminal includes: adding a diversity antenna to the antenna structure, the receiving antenna of the diversity antenna matches the frequency corresponding to the SAR peak value of the main antenna, and the current distribution of the frequency corresponding to the main antenna SAR peak is dispersed by the diversity antenna To reduce the SAR peak value of the main antenna; or to set multiple antennas and select one of the antennas whose maximum SAR power corresponds to a SAR value that does not exceed the preset SAR threshold as the main antenna of the terminal. The way the terminal hardware is structured. And reduce the terminal's SAR value by reducing the transmit power when the terminal sends a signal.
然而,能够同时支持LTE和NR两种制式的终端,当处于同一频段时,其LTE和NR一般采用的是共天线设计,现有技术的采用分级天线对主天线进行分流或者从多天线中选取未超过预设SAR阈值的天线作为主天线, 会在增加了终端结构复杂的情况下未考虑同时工作的LTE和NR的数据传输情况,从而影响终端进行数据传输的质量和速度;现有技术中的通过降低终端发送信号时的发射功率来降低终端的SAR值,也只是单纯的降低了整体的发射功率,同样未考虑到同时工作的LTE和NR的数据传输情况,从而影响终端进行数据传输的质量和速度。However, terminals that can support both LTE and NR standards. When they are in the same frequency band, their LTE and NR generally use a common antenna design. In the prior art, hierarchical antennas are used to split the main antenna or select from multiple antennas. The antenna that does not exceed the preset SAR threshold is used as the main antenna, and it will not consider the data transmission situation of LTE and NR working at the same time when the terminal structure is complicated, thereby affecting the quality and speed of data transmission by the terminal; in the prior art, The SAR value of the terminal is reduced by reducing the transmission power when the terminal sends signals. It also simply reduces the overall transmission power. It also does not take into account the data transmission of LTE and NR working at the same time, which affects the data transmission of the terminal. Quality and speed.

The attached drawings are for reference only and are not intended to limit the embodiments of the present application.
随着5G技术的快速发展,终端能够支持5G无线网双连接协议架构,即同时支持LTE和NR两种制式,且终端在工作频段上工作时,LTE和NR两种制式处于同时工作状态,其中,通用移动通信***陆地无线接入网(E-UTRAN,Evolved-Universal Mobile Telecommunications System-Terrestrial Radio Access Network)和NR双连接终端,即EN-DC终端,使用LTE分组核心网(EPC,Evolved Packet Core)作为核心网,使用LTE协议栈及LTE相关接口作为网元间信令交互与数据传输的基础;NR和 E-UTRAN双连接终端,即NE-DC终端,使用NR下一代核心(NG,Next Generation)Core作为核心网,使用NR协议栈及NR相关接口作为网元间信令交互与数据传输的基础。With the rapid development of 5G technology, the terminal can support the 5G wireless network dual connection protocol architecture, that is, it supports both LTE and NR standards, and when the terminal works in the operating frequency band, the LTE and NR modes are working simultaneously, of which , Universal Mobile Communication System Terrestrial Radio Access Network (E-UTRAN, Evolved-Universal Mobile Telecommunications System-Terrestrial Radio Access Network) and NR dual-connected terminals, namely EN-DC terminals, using LTE packet core network (EPC, Evolved Packet Packet Core ) As the core network, using the LTE protocol stack and LTE-related interfaces as the basis for signaling interaction and data transmission between network elements; NR and E-UTRAN dual-connection terminals, namely NE-DC terminals, use the NR next-generation core (NG, Next Generation) Core is the core network, and uses the NR protocol stack and NR related interfaces as the basis for signaling interaction and data transmission between network elements.

When the LTE and NR systems work on two discrete segments of the same frequency band at the same time, they are called in-band discontinuous terminals. The time slot scheduling method proposed in this application is used to solve the problem that the SAR value of the in-band continuous terminal and the in-band discontinuous terminal exceeds the standard.
由于LTE一般采用静态或半静态的上下行时隙配比,故,LTE的上下行配比确定之后不会再进行大幅度的更改,而NR则采用半静态或动态的上下行时隙配比,因此,本申请基于优先考虑LTE的上下行配比情况,然后决定NR的上下行配比调度的原则提出下述实施例。Because LTE generally uses static or semi-static uplink and downlink timeslot ratios, the LTE uplink and downlink ratios will not be changed significantly after determination, while NR uses semi-static or dynamic uplink and downlink timeslot ratios. Therefore, this application proposes the following embodiments based on the principle of preferentially considering the uplink and downlink allocation of LTE and then determining the uplink and downlink allocation scheduling of NR.

本申请实施例中,当终端接入第一小区时,终端从***广播消息中读取第一小区的上下行时隙配置信息,并根据第一小区的上下行时隙配置信息确定出终端工作在工作频段时,LTE的上行时隙占比UL LTE,其中,LTE的上行时隙占比UL LTE为上行时隙占上下行时隙配置信息的比值。 In the embodiment of the present application, when the terminal accesses the first cell, the terminal reads the uplink and downlink timeslot configuration information of the first cell from the system broadcast message, and determines the terminal operation according to the uplink and downlink timeslot configuration information of the first cell. In the operating frequency band, the uplink time slot ratio of LTE is UL LTE , and the uplink time slot ratio of LTE UL LTE is the ratio of uplink time slot to uplink and downlink time slot configuration information.

本申请实施例中,如图2所示,LTE上下行数据传输是以子帧为长度单位进行上下行传输的。In the embodiment of the present application, as shown in FIG. 2, the LTE uplink and downlink data transmission is performed by using a subframe as a length unit for uplink and downlink transmission.
S102、根据上行时隙占比和预设最大上行占比,得到NR的最大上行符号占比,并将最大上行符号占比发送至基站,以调度基站至多为NR分配最大上行符号占比,预设最大上行占比为在工作频段的最大发射功率对应的最大上行占比。S102. Obtain the maximum uplink symbol ratio of the NR according to the uplink time slot ratio and the preset maximum uplink ratio, and send the maximum uplink symbol ratio to the base station to schedule the base station to allocate the maximum uplink symbol ratio to the NR at most. Let the maximum uplink share be the maximum uplink share corresponding to the maximum transmit power in the operating frequency band.
当终端根据第一小区的上下行时隙配置信息,确定LTE的上行时隙占比之后,终端根据上行时隙占比和预设最大上行占比,得到NR的最大上行符号占比,并将最大上行符号占比发送至基站。After the terminal determines the LTE uplink time slot ratio according to the uplink and downlink time slot configuration information of the first cell, the terminal obtains the maximum uplink symbol ratio of the NR according to the uplink time slot ratio and the preset maximum uplink ratio, and The maximum proportion of uplink symbols is sent to the base station.
本申请实施例中,由于LTE和NR的平均上行时隙占比不超过最大发射功率的最大上行占比时,终端的SAR值才能够达标,故,终端先获取工作频段对应的最大发射功率的最大上行占比,并将最大上行占比乘2得到最大发射功率对应的预设最大上行占比,之后,终端计算预设最大上行占比与上行时隙占比的差值,并将预设最大上行占比与上行时隙占比的差值确定为NR的最大上行符号占比,终端将NR的最大上行符号占比发送至基站,基站根据NR的最大上行符号占比,为NR至多分配最大上行符号占比。In the embodiment of the present application, because the average uplink time slot ratio of LTE and NR does not exceed the maximum uplink ratio of the maximum transmission power, the SAR value of the terminal can meet the standard. Therefore, the terminal first obtains the maximum transmission power corresponding to the operating frequency band. The maximum uplink ratio and multiplying the maximum uplink ratio by 2 to obtain the preset maximum uplink ratio corresponding to the maximum transmit power. After that, the terminal calculates the difference between the preset maximum uplink ratio and the uplink time slot ratio, and The difference between the maximum uplink share and the uplink time slot share is determined as the maximum uplink symbol share of the NR. The terminal sends the maximum uplink symbol share of the NR to the base station, and the base station allocates at most NR based on the maximum uplink symbol share of the NR. Maximum uplink symbol ratio.
本申请实施例中,如图3所示,设NR上行占比的统计窗口长度为window,每一个window由S1-Sn+2个符号组成,在基站在调度NR的上行占比时以window长度为单位进行调度。In the embodiment of the present application, as shown in FIG. 3, the statistical window length of the NR uplink ratio is set to window, and each window is composed of S1-Sn + 2 symbols. The base station uses the window length when scheduling the NR uplink ratio. Scheduling for the unit.
示例性的,终端在某一频段电磁波吸收比值(SAR,Specific AbsorptionRate)值不超标时的最大发射功率为26dBM,终端获取自身在该频段中26dBM的最大上行占比为maxUplinkDutyCycle,为使得终端的SAR值符合标准,终端的LTE的上行时隙占比UL LTE和NR的上行符号占比UL NR需要满足公式(1),即: Exemplarily, the maximum transmit power of the terminal when the specific electromagnetic absorption ratio (SAR) value in a certain frequency band does not exceed the standard is 26dBM, and the terminal obtains the maximum uplink share of 26dBM in this frequency band as maxUplinkDutyCycle, so that the terminal ’s SAR The value complies with the standard. The uplink slot ratio of the terminal's LTE UL LTE and the uplink symbol ratio of the NR UL NR need to satisfy formula (1), that is:
Average(UL LTE+UL NR)≤maxUplinkDutyCycle  (1) Average (UL LTE + UL NR ) ≤maxUplinkDutyCycle (1)
因此,终端根据LTE的上行时隙占比UL LTE和最大上行占比maxUplinkDutyCycle,计算出NR的最大上行符号占比为: Therefore, the terminal calculates the maximum uplink symbol ratio of NR according to UL LTE uplink slot ratio UL LTE and maximum uplink ratio maxUplinkDutyCycle:
UL NR-max=2×maxUplinkDutyCycle-UL LTE  (2) UL NR-max = 2 × maxUplinkDutyCycle-UL LTE (2)
可以理解的是,由于同样LTE和NR的发射功率产生的SAR值是一样的,且LTE一般采用静态或半静态的上下行时隙配比,故,终端先确定出在工作频段的最大发射功率对应的最大上行占比,并根据第一小区的上下行时隙配置信息,确定LTE的上行时隙占比,之后,终端根据上行时隙占比和预设最大上行占比,得到NR的最大上行符号占比,并向基站为NR调度该最大上行符号占比,终端通过确定NR的上下行时隙调度的方式避免SAR值超标,能够使得同时支持LTE和NR两种制式的终端满足标准限定的SAR值的前提下,提升数据传输的质量和速度。It can be understood that because the SAR values generated by the same LTE and NR transmit power are the same, and LTE generally uses static or semi-static uplink and downlink time slot ratios, the terminal first determines the maximum transmit power in the operating frequency band.

本申请实施例中,当终端判断出基站为NR分配的第一上行符号占比不满足SRA值标准时,终端按照预设调整策略,降低LTE和/或NR的发射功率,以使LTE和NR的发射功率满足预设发射要求。In the embodiment of the present application, when the terminal determines that the ratio of the first uplink symbol allocated by the base station to the NR does not meet the SRA value standard, the terminal reduces the transmission power of LTE and / or NR according to a preset adjustment policy, so that the LTE and NR The transmission power meets the preset transmission requirements.
本申请实施例中,预设发射要求为LTE的发射参考值和NR的发射参考值之和小于或者等于最大发射参考值,其中,LTE的发射参考值由LTE的当前发射功率与上行时隙占比确定,NR的发射参考值由LTE的当前发射功率与第一上行符号占比确定,最大发射参考值由最大发射功率和预设最大上行占比确定。In the embodiment of the present application, the preset transmission requirement is that the sum of the transmission reference value of LTE and the transmission reference value of NR is less than or equal to the maximum transmission reference value, wherein the transmission reference value of LTE is occupied by the current transmission power of LTE and the uplink time slot. The transmission reference value of the NR is determined by the current transmission power of the LTE and the first uplink symbol ratio, and the maximum transmission reference value is determined by the maximum transmission power and a preset maximum uplink ratio.
本申请实施例中,LTE的发射参考值为LTE的当前发射功率与上行时隙占比相乘得到的发射参考值,NR的发射参考值为LTE的当前发射功率与第一上行符号占比相乘得到的发射参考值,最大发射参考值为最大发射功率和预设最大上行占比相乘得到的发射参考值。In the embodiment of the present application, the transmission reference value of LTE is a transmission reference value obtained by multiplying the current transmission power of LTE by the uplink slot ratio, and the transmission reference value of NR is equal to the current transmission power of LTE and the first uplink symbol ratio. The transmission reference value obtained by multiplying, and the maximum transmission reference value is a transmission reference value obtained by multiplying the maximum transmission power and a preset maximum uplink ratio.
本申请实施例中,LTE和NR的发射功率满足公式(3)时,表征LTE和NR的发射功率满足预设发射要求,In the embodiment of the present application, when the transmission power of LTE and NR satisfies formula (3), it means that the transmission power of LTE and NR meets a preset transmission requirement,
P LTE×UL LTE+P NR×UL NR≤ENDC power class×maxUplinkDutyCycle  (3) P LTE × UL LTE + P NR × UL NR ≤ENDC power class × maxUplinkDutyCycle (3)

本申请实施例中,预设调整策略为终端优先降低辅载波的发射功率,对于EN-DC终端而言,辅载波为NR,此时,终端降低NR的发射功率; 对于NE-DC终端而言,辅载波为LTE,此时,终端降低LTE的发射功率。In the embodiment of the present application, the preset adjustment strategy is that the terminal preferentially reduces the transmit power of the secondary carrier.

At this time, the terminal reduces the transmission power of LTE.
可以理解的是,由于同样LTE和NR的发射功率产生的SAR值是一样的,且LTE一般采用静态或半静态的上下行时隙配比,故,终端先确定出在工作频段的最大发射功率对应的最大上行占比,并根据第一小区的上下行时隙配置信息,确定LTE的上行时隙占比,之后,终端根据上行时隙占比和预设最大上行占比,得到NR的最大上行符号占比,并向基站为NR调度该最大上行符号占比,当终端判断出第一上行符号占比大于所述最大上行符号占比时,终端降低LTE和/或NR的发射功率,终端通过确定NR的上下行时隙调度的方式结合降低LTE和/或NR的发射功率的方式避免SAR值超标,能够使得同时支持LTE和NR两种制式的终端满足标准限定的SAR值的前提下,提升数据传输的质量和速度。It can be understood that because the SAR values generated by the same LTE and NR transmit power are the same, and LTE generally uses static or semi-static uplink and downlink time slot ratios, the terminal first determines the maximum transmit power in the operating frequency band. The corresponding maximum uplink ratio, and determine the uplink time slot ratio of LTE according to the uplink and downlink time slot configuration information of the first cell. After that, the terminal obtains the maximum NR according to the uplink time slot ratio and the preset maximum uplink ratio.

工业实用性Industrial applicability
在本申请实施例中,由于同样LTE和NR的发射功率产生的SAR值是一样的,且LTE一般采用静态或半静态的上下行时隙配比,故,终端先确定出在工作频段的最大发射功率对应的最大上行占比,并根据第一小区的上下行时隙配置信息,确定LTE的上行时隙占比,之后,终端根据上行时隙占比和预设最大上行占比,得到NR的最大上行符号占比,并向基站为NR调度该最大上行符号占比,终端通过确定NR的上下行时隙调度的方式避免SAR值超标,能够使得同时支持LTE和NR两种制式的终端满足标准限定的SAR值的前提下,提升数据传输的质量和速度。In the embodiment of the present application, since the SAR values generated by the same transmission power of LTE and NR are the same, and LTE generally uses static or semi-static uplink and downlink time slot ratios, the terminal first determines the maximum value in the operating frequency band. The maximum uplink ratio corresponding to the transmission power, and determines the uplink slot ratio of LTE according to the uplink and downlink slot configuration information of the first cell. After that, the terminal obtains the NR according to the uplink slot ratio and the preset maximum uplink ratio. The maximum uplink symbol ratio is calculated, and the maximum uplink symbol ratio is scheduled to the base station for the NR. The terminal determines the NR uplink and downlink time slot scheduling to prevent the SAR value from exceeding the standard.
