Description

参考信号接收功率阈值的发送和接收方法及装置Method and device for transmitting and receiving reference signal receiving power threshold 技术领域Technical field
本申请涉及通信技术,尤其涉及一种参考信号接收功率阈值的发送和接收方法及装置。This application relates to communication technology, and in particular to a method and device for sending and receiving a reference signal received power threshold.
背景技术Background technique
目前,正在研究在窄带物联网(Narrow Band Internet of Things,NB-IoT)中增加上行免调度传输技术,上行免调度传输还可以称为预配置上行资源中的传输(transmission in preconfigured UL resources,PUR)、免调度传输(grant-free transmission)或者预配置资源中的上行链路传输(UpLink transmission in preconfigured resources)等,以下均称为上行免调度传输。上行免调度传输技术中,基站为终端设备预先配置上行资源,当有上行数据要进行传输时,终端设备可以直接在预先配置的上行资源上按照预先规定的发送方式进行上行数据传输,基站根据对上行数据的解调情况发送反馈信息。可以看出,采用上行免调度传输技术,终端设备不需要向基站申请上行资源,也不需要等待基站下发上行调度信息,减少了流程,具有降低功耗时延、降低信令开销等优势。Currently, research is underway to add uplink scheduling-free transmission technology to the Narrow Band Internet of Things (NB-IoT). Uplink scheduling-free transmission can also be called transmission in preconfigured UL resources (PUR). ), scheduling-free transmission (grant-free transmission), or uplink transmission in pre-configured resources (UpLink transmission in preconfigured resources), etc., are all referred to as uplink scheduling-free transmission below. In the uplink scheduling-free transmission technology, the base station pre-configures uplink resources for the terminal equipment. When there is uplink data to be transmitted, the terminal equipment can directly transmit the uplink data on the pre-configured uplink resources according to the predetermined transmission mode. The demodulation of the uplink data sends feedback information. It can be seen that using the uplink scheduling-free transmission technology, the terminal device does not need to apply for uplink resources from the base station, nor does it need to wait for the base station to issue uplink scheduling information, which reduces the process and has the advantages of reducing power consumption delay and signaling overhead.
通常终端设备传输上行数据时,同一小区内不同终端设备由于位置不同,终端设备发送的上行数据到达基站的时间可能会不同,这会造成用户间的干扰。时间提前量(Timing Advance,TA)的作用就是让终端设备调整上行传输时间,使得小区内所有终端设备发送的上行数据到达基站的时间相同,以避免用户间干扰。Generally, when a terminal device transmits uplink data, due to different locations of different terminal devices in the same cell, the time at which the uplink data sent by the terminal device reaches the base station may be different, which may cause interference between users. The function of Timing Advance (TA) is to allow terminal equipment to adjust the uplink transmission time so that the uplink data sent by all terminal equipment in the cell arrive at the base station at the same time to avoid interference between users.
终端设备可以根据基站配置的参考信号接收功率(Reference Signal Received Power,RSRP)阈值(threshold)来判断TA有否有效,在TA有效的情况下,终端设备才可以采用上行免调度传输技术直接发送上行数据。但是现在的标准讨论中,TA是否有效的判断结果可能会不适应终端设备状态的改变。比如,如果终端设备在TA无效的情况下使用该TA发送数据,则会导致网络设备解调不准确、浪费网络资源和增加终端设备的功耗。如果终端设备在TA有效的情况下,因针对TA是否有效的判断出现错误而导致终端设备不能使用上行免调度传输,则这种情况下终端设备通常会改用传统的数据传输方式进行数据传输,显然会增加通信设备的功耗和网络资源开销。The terminal equipment can judge whether the TA is valid according to the RSRP (Reference Signal Received Power) threshold configured by the base station. Only when the TA is valid, the terminal equipment can use the uplink scheduling-free transmission technology to directly send the uplink. data. However, in the current standard discussion, the result of judging whether the TA is valid may not adapt to the change of the terminal equipment state. For example, if the terminal device uses the TA to send data when the TA is invalid, it will cause the network device to demodulate inaccurately, waste network resources and increase the power consumption of the terminal device. If the terminal device is unable to use uplink scheduling-free transmission due to an error in the judgment of whether the TA is valid when the TA is valid, the terminal device will usually use the traditional data transmission method for data transmission in this case. Obviously, it will increase the power consumption of communication equipment and network resource overhead.

图2为本申请RSRP阈值的发送和接收方法实施例的流程图,如图2所示,本实施例的方法可以包括:FIG. 2 is a flowchart of an embodiment of a method for sending and receiving RSRP thresholds of this application. As shown in FIG. 2, the method of this embodiment may include:
步骤201、网络设备为通信设备配置第一RSRP阈值集合。Step 201: The network device configures a first RSRP threshold set for the communication device.
第一RSRP阈值集合包括一个或多个RSRP阈值,第一RSRP阈值集合用于确定通信设备的第一TA是否有效(valid)。即通信设备可以根据第一RSRP阈值集合中的一个或多个RSRP阈值判断第一TA是否有效。示例性的:The first RSRP threshold set includes one or more RSRP thresholds, and the first RSRP threshold set is used to determine whether the first TA of the communication device is valid (valid). That is, the communication device may determine whether the first TA is valid according to one or more RSRP thresholds in the first RSRP threshold set. Exemplary:
若第一RSRP阈值集合中包括一个RSRP阈值NRSRP threshold,则通信设备在满足|NRSRP change|≤NRSRP threshold时,认为第一TA有效,其中,NRSRP change=NRSRP now-NRSRP ref,NRSRP now表示通信设备当前测量得到的RSRP值,NRSRP ref表示RSRP参考值,其可以是通信设备前一次测量得到的RSRP值,也可以是通信设备获得第一TA时测量得到的RSRP值,本申请对此不做具体限定。 If the first RSRP threshold set includes an RSRP threshold NRSRP threshold , the communication device considers the first TA valid when |NRSRP change |≤NRSRP threshold is satisfied, where NRSRP change = NRSRP now- NRSRP ref , and NRSRP now represents the communication device The RSRP value obtained by the current measurement, NRSRP ref represents the RSRP reference value, which can be the RSRP value measured by the communication device last time, or the RSRP value measured when the communication device obtains the first TA. This application will not be specific limited.
若第一RSRP阈值集合中包括两个RSRP阈值NRSRP threshold1和NRSRP threshold2,则通信设备在满足NRSRP threshold1≤NRSRP change≤NRSRP threshold2时,认为第一TA有效。 If the first RSRP threshold set includes two RSRP thresholds NRSRP threshold1 and NRSRP threshold2 , the communication device considers the first TA to be valid when NRSRP threshold1 ≤ NRSRP change ≤ NRSRP threshold2 is satisfied.
第一TA的作用就是让通信设备调整上行传输时间,使得小区内所有通信设备发送的上行数据到达网络设备的时间相同,以避免用户间干扰。最初时网络设备给通信设备配置第一TA和第一RSRP阈值集合,通信设备可以根据第一RSRP阈值集合中的一个或多个RSRP阈值(RSRP threshold)来判断第一TA有否有效,在第一TA有效的情况下,通信设备才可以采用上行免调度传输技术直接发送上行数据。网络设备可以将配置给通信设备的第一TA直接发送给通信设备。The role of the first TA is to allow the communication equipment to adjust the uplink transmission time so that the uplink data sent by all communication equipment in the cell arrive at the network equipment at the same time to avoid interference between users. Initially, the network device configures the first TA and the first RSRP threshold set for the communication device. The communication device can determine whether the first TA is valid according to one or more RSRP thresholds in the first RSRP threshold set. Only when a TA is valid, the communication device can directly send uplink data using the uplink scheduling-free transmission technology. The network device may directly send the first TA configured to the communication device to the communication device.
示例性的,假设最初时通信设备距离网络设备的距离x=1500m,对应于该距离网络设备给通信设备配置的第一RSRP阈值集合包括两个阈值-6.3dB和10.3dB,通信设备在满足-6.3dB≤NRSRP change≤10.3dB时认为第一TA有效,NRSRP change=NRSRP now-NRSRP ref,NRSRP now表示通信设备当前测量得到的RSRP值,NRSRP ref表示RSRP参考值,其可以是通信设备前一次测量得到的RSRP值,也可以是通信设备获得第一TA时测量得到的RSRP值,本申请对此不做具体限定。 Exemplarily, assuming that the distance between the communication device and the network device is x=1500m at the beginning, the first RSRP threshold set configured by the network device for the communication device corresponding to this distance includes two thresholds -6.3dB and 10.3dB, and the communication device is satisfying- When 6.3dB≤NRSRP change ≤10.3dB, the first TA is considered valid, NRSRP change = NRSRP now- NRSRP ref , NRSRP now represents the RSRP value currently measured by the communication device, and NRSRP ref represents the RSRP reference value, which can be the previous time of the communication device The measured RSRP value may also be the RSRP value measured when the communication device obtains the first TA, which is not specifically limited in this application.
步骤202、通信设备向网络设备发送第一信息。Step 202: The communication device sends the first information to the network device.
通信设备发送的第一信息包括承载于数据信道的上行数据和/或上行控制信令,或承 载于随机接入信道(Random Access Channel,RACH)的前导码(preamble)。当根据第一RSRP阈值集合确定第一TA有效时,该第一信息可以是承载于数据信道的上行数据和/或上行控制信令。当根据第一RSRP阈值集合确定第一TA失效时,该第一信息可以是承载于随机接入信道的前导码。The first information sent by the communication device includes uplink data and/or uplink control signaling carried on a data channel, or a preamble carried on a random access channel (Random Access Channel, RACH). When it is determined that the first TA is valid according to the first RSRP threshold set, the first information may be uplink data and/or uplink control signaling carried on the data channel. When it is determined that the first TA is invalid according to the first RSRP threshold set, the first information may be the preamble carried on the random access channel.
步骤203、网络设备根据第一信息为通信设备确定第二RSRP阈值集合。Step 203: The network device determines a second RSRP threshold set for the communication device according to the first information.
第二RSRP阈值集合包括一个或多个RSRP阈值,第二RSRP阈值集合用于确定通信设备的第二TA是否有效,第二TA等于第一TA与第一调整量的和,第二RSRP阈值集合中的每个RSRP阈值分别等于第一RSRP阈值集合中的每个RSRP阈值与一个调整量的和。第二TA的作用就是在网络设备和通信设备进行数据传输的过程中,让通信设备及时调整上行传输时间,使得小区内所有通信设备发送的上行数据到达网络设备的时间相同,以避免用户间干扰。而在网络设备和通信设备进行数据传输的过程中,从第一TA到第二TA发生了TA变化,通信设备的位置也可能发生变化,如果如上所述,再采用第一RSRP阈值集合确定通信设备的第二TA是否有效,很可能是不准确的,因此需要对第一RSRP阈值集合调整,采用调整后得到的第二RSRP阈值集合来确定第二TA是否有效。The second RSRP threshold set includes one or more RSRP thresholds, the second RSRP threshold set is used to determine whether the second TA of the communication device is valid, the second TA is equal to the sum of the first TA and the first adjustment, and the second RSRP threshold set Each RSRP threshold in is equal to the sum of each RSRP threshold in the first RSRP threshold set and an adjustment value. The role of the second TA is to allow the communication equipment to adjust the uplink transmission time in time during the data transmission process of the network equipment and the communication equipment, so that the uplink data sent by all communication equipment in the cell arrives at the network equipment at the same time to avoid interference between users . In the process of data transmission between network equipment and communication equipment, TA changes from the first TA to the second TA, and the location of the communication equipment may also change. If as described above, the first RSRP threshold set is used to determine the communication. Whether the second TA of the device is valid is likely to be inaccurate. Therefore, the first RSRP threshold set needs to be adjusted, and the adjusted second RSRP threshold set is used to determine whether the second TA is valid.
网络设备可以根据第一信息确定第二TA,再根据第一TA和第二TA确定是否需要进行TA更新,例如,第二TA和第一TA不同就表示需要进行TA更新。若确定需要进行TA更新,则根据第二TA确定第二RSRP阈值集合,即网络设备只有在需要进行TA更新时,才会根据第二TA确定第二RSRP阈值集合。网络设备向通信设备发送第二TA可以采用两种方式:一种是网络设备将配置给通信设备的第二TA直接发送给通信设备;另一种是网络设备将第二TA相对于第一TA的第一调整量发送给通信设备。The network device may determine the second TA according to the first information, and then determine whether a TA update is required according to the first TA and the second TA. For example, the difference between the second TA and the first TA indicates that the TA update is required. If it is determined that a TA update is required, the second RSRP threshold set is determined according to the second TA, that is, the network device determines the second RSRP threshold set according to the second TA only when the TA update is required. The network device can send the second TA to the communication device in two ways: one is that the network device directly sends the second TA configured to the communication device to the communication device; the other is that the network device sends the second TA relative to the first TA The first adjustment amount is sent to the communication device.
示例性的,假设最初时通信设备距离网络设备的距离x=1500m,对应于该距离网络设备配置的第一TA为19,第一RSRP阈值集合包括两个阈值-6.3dB和10.3dB。通信设备在和网络设备进行数据传输的过程中,通信设备远离网络设备移动了500m(1500m→2000m),此时如果不更新RSRP阈值集合,则TA是否有效的判断可能会不准确,即第一TA实际上已经失效,但通信设备根据第一RSRP阈值集合判断第一TA有效,通信设备会用第一TA发送上行数据,导致网络设备解调不准确、浪费网络资源和增加通信设备的功耗,并对其他通信设备造成干扰。因此当通信设备远离网络设备时,RSRP阈值集合的区间应变小。或者通信设备在和网络设备进行数据传输的过程中,通信设备朝向网络设备移动了500m(1500m→1000m),此时如果不更新RSRP阈值集合,则TA是否有效的判断可能会不准确,即第一TA实际上仍然有效,但通信设备根据第一RSRP阈值集合判断第一TA失效,导致通信设备不能使用上行免调度传输。这种情况下通信设备通常会改用传统的数据传输方式进行数据传输。与上行免调度传输相比,使用传统的数据传输方式进行数据传输,会增加通信设备的功耗和网络资源开销。因此当通信设备朝向网络设备时,RSRP阈值集合的区间应变大。Exemplarily, assuming that the distance x between the communication device and the network device at the beginning is x=1500m, the first TA corresponding to the distance network device configuration is 19, and the first RSRP threshold set includes two thresholds -6.3dB and 10.3dB. In the process of data transmission between the communication device and the network device, the communication device moves 500m away from the network device (1500m→2000m). At this time, if the RSRP threshold set is not updated, the judgment of whether the TA is valid may be inaccurate, that is, the first TA has actually failed, but the communication device judges that the first TA is valid according to the first RSRP threshold set. The communication device will use the first TA to send uplink data, resulting in inaccurate demodulation by the network device, wasting network resources, and increasing the power consumption of the communication device , And cause interference with other communication equipment. Therefore, when the communication device is far away from the network device, the interval of the RSRP threshold set should be small. Or in the process of data transmission between the communication device and the network device, the communication device moves 500m (1500m→1000m) toward the network device. If the RSRP threshold set is not updated at this time, the judgment of whether the TA is valid may be inaccurate. A TA is actually still valid, but the communication device judges that the first TA is invalid according to the first RSRP threshold set, which results in the communication device not being able to use uplink scheduling-free transmission. In this case, the communication device usually uses the traditional data transmission method for data transmission. Compared with uplink scheduling-free transmission, using traditional data transmission methods for data transmission will increase the power consumption of communication equipment and network resource overhead. Therefore, when the communication device faces the network device, the interval of the RSRP threshold set should be large.
表1示出了前述两种变化下有效TA和RSRP阈值集合的对应关系,NRSRP change=NRSRP now-NRSRP ref,NRSRP now表示通信设备当前测量得到的RSRP值,NRSRP ref表示RSRP参考值,其可以是通信设备前一次测量得到的RSRP值,也可以是通 信设备获得第一TA时测量得到的RSRP值,本申请对此不做具体限定,δ awaydB和δ closedB是RSRP阈值集合中的两个RSRP阈值。 Table 1 shows the corresponding relationship between the effective TA and RSRP threshold set under the aforementioned two changes, NRSRP change = NRSRP now- NRSRP ref , NRSRP now represents the RSRP value currently measured by the communication device, and NRSRP ref represents the RSRP reference value, which can be It is the RSRP value measured by the communication device last time, or it can be the RSRP value measured when the communication device obtains the first TA. This application does not specifically limit this. δ away dB and δ close dB are two of the RSRP threshold set. RSRP threshold.

如表1所示,
Figure PCTCN2019098409-appb-000002
当通信设备远离网络设备移动了500m(1500m→2000m)时,网络设备将通信设备的TA从19(第一TA)调整为26(第二TA),相应的,第二RSRP阈值集合包括两个阈值-4.9dB和7.1dB。当通信设备朝向网络设备移动了500m(1500m→1000m)时,网络设备将通信设备的TA从19(第一TA)调整为13(第二TA),相应的,第二RSRP阈值集合包括两个阈值-8.7dB和19.8dB。
As shown in Table 1,
Figure PCTCN2019098409-appb-000002
When the communication device moves 500m away from the network device (1500m→2000m), the network device adjusts the TA of the communication device from 19 (first TA) to 26 (second TA). Correspondingly, the second RSRP threshold set includes two The threshold is -4.9dB and 7.1dB. When the communication device moves 500m (1500m→1000m) toward the network device, the network device adjusts the TA of the communication device from 19 (first TA) to 13 (second TA). Correspondingly, the second RSRP threshold set includes two The threshold is -8.7dB and 19.8dB.
需要说明的是,上述当通信设备远离网络设备移动了500m(1500m→2000m)时,第二TA(26)等于第一TA(19)与第一调整量(7)的和。当通信设备朝向网络设备移动了500m(1500m→1000m)时,第二TA(13)等于第一TA(19)与第一调整量(-6)的和。但是在通信设备移动的过程中,也可能存在TA没有发生变化的情况,即第一调整量为0,此时第一TA和第二TA相等,不需要进行TA更新。It should be noted that when the communication device moves away from the network device by 500 m (1500 m→2000 m), the second TA (26) is equal to the sum of the first TA (19) and the first adjustment (7). When the communication device moves 500m (1500m→1000m) toward the network device, the second TA (13) is equal to the sum of the first TA (19) and the first adjustment (-6). However, during the movement of the communication device, there may also be a situation in which the TA does not change, that is, the first adjustment amount is 0. At this time, the first TA and the second TA are equal, and no TA update is required.
另外,上述当通信设备远离网络设备移动了500m(1500m→2000m)时,第一RSRP阈值集合的区间中的δ away(第一RSRP阈值)-6.3dB变为第二RSRP阈值集合的区间中的δ away(第一RSRP阈值)-4.9dB,δ away调整量为1.4dB,第一RSRP阈值集合的区间中的δ close(第二RSRP阈值)10.3dB变为第二RSRP阈值集合的区间中的δ close(第二RSRP阈值)7.1dB,δ close调整量为-3.2dB。当通信设备朝向网络设备移动了500m(1500m→1000m)时,第一RSRP阈值集合的区间中的δ away(第一RSRP阈值)-6.3dB变为第二RSRP阈值集合的区间中的δ away(第一RSRP阈值)-8.7dB,δ away调整量为-2.4B,第一RSRP阈值集合的区间中的δ close(第二RSRP阈值)10.3dB变为第二RSRP阈值集合的区间中的δ close (第二RSRP阈值)19.8dB,δ close调整量为9.5dB。但是在通信设备移动的过程中,也可能存在RSRP阈值集合中的部分RSRP阈值发生变化的情况,即RSRP阈值集合中的部分RSRP阈值分别对应的调整量为0;也可能存在RSRP阈值集合没有发生变化的情况,即每个RSRP阈值分别对应的调整量均为0。 In addition, when the communication device moves 500m away from the network device (1500m→2000m), the δ away (first RSRP threshold)-6.3dB in the interval of the first RSRP threshold set becomes the interval of the second RSRP threshold set. δ away (first RSRP threshold) -4.9dB, δ away adjustment is 1.4dB, δ close (second RSRP threshold) 10.3dB in the interval of the first RSRP threshold set becomes the interval of the second RSRP threshold set δ close (the second RSRP threshold) is 7.1dB, and the adjustment amount of δ close is -3.2dB. When the communication device moves 500m (1500m→1000m) toward the network device, the δ away (first RSRP threshold)-6.3dB in the interval of the first RSRP threshold set becomes δ away ( The first RSRP threshold) -8.7dB, the δ away adjustment is -2.4B, the δ close (second RSRP threshold) 10.3dB in the interval of the first RSRP threshold set becomes δ close in the interval of the second RSRP threshold set (The second RSRP threshold) 19.8dB, and the δ close adjustment amount is 9.5dB. However, during the movement of the communication device, some RSRP thresholds in the RSRP threshold set may change, that is, some RSRP thresholds in the RSRP threshold set correspond to an adjustment value of 0; there may also be no RSRP threshold set The change situation, that is, the adjustment amount corresponding to each RSRP threshold is 0.
步骤204、网络设备向通信设备发送RSRP指示信息,RSRP指示信息用于指示第二RSRP阈值集合。Step 204: The network device sends RSRP indication information to the communication device, where the RSRP indication information is used to indicate the second RSRP threshold set.
网络设备向通信设备发送RSRP指示信息,可以将RSRP指示信息承载于控制信息,例如下行控制信息(Downlink Control Information,DCI)。The network device sends RSRP indication information to the communication device, and the RSRP indication information may be carried in control information, such as Downlink Control Information (DCI).

网络设备向通信设备发送RSRP指示信息,也可以将RSRP指示信息承载于数据信道。可选的,网络设备可以将RSRP指示信息承载于在数据信道中传输的媒体接入控制层控制元素(Media Access Control Control Element,MAC CE)或者无线资源控制(Radio Resource Control,RRC)信令。The network device sends RSRP indication information to the communication device, and may also carry the RSRP indication information on the data channel. Optionally, the network device may carry the RSRP indication information in a media access control layer control element (Media Access Control Control Element, MAC CE) or radio resource control (Radio Resource Control, RRC) signaling transmitted in the data channel.
本申请中第一RSRP阈值集合和第二RSRP阈值集合中的RSRP阈值是一一对应的,例如,第一RSRP阈值集合中的第一RSRP阈值和第二RSRP阈值集合中的第一RSRP阈值对应,前者和对应的调整量求和后得到后者,第一RSRP阈值集合中的第二RSRP阈值和第二RSRP阈值集合中的第二RSRP阈值对应,前者和对应的调整量求和后得到后者。基于此,RSRP指示信息可以包括第二RSRP阈值集合中的每个RSRP阈值相对于第一RSRP阈值集合中的每个RSRP阈值的调整量,即网络设备在RSRP指示信息中携带的是第二RSRP阈值集合中每个RSRP阈值对应的调整量。或者,RSRP指示信息也可以包括第二RSRP阈值集合中的每个RSRP阈值,即网络设备在RSRP指示信息中携带的是第二RSRP阈值集合中每个RSRP阈值。In this application, the RSRP thresholds in the first RSRP threshold set and the second RSRP threshold set are in one-to-one correspondence. For example, the first RSRP threshold in the first RSRP threshold set corresponds to the first RSRP threshold in the second RSRP threshold set. , The former and the corresponding adjustments are summed to obtain the latter. The second RSRP threshold in the first RSRP threshold set corresponds to the second RSRP threshold in the second RSRP threshold set. The former and the corresponding adjustments are summed to obtain the By. Based on this, the RSRP indication information may include the adjustment amount of each RSRP threshold in the second RSRP threshold set relative to each RSRP threshold in the first RSRP threshold set, that is, the network device carries the second RSRP in the RSRP indication information. The adjustment value corresponding to each RSRP threshold in the threshold set. Alternatively, the RSRP indication information may also include each RSRP threshold in the second RSRP threshold set, that is, the RSRP indication information carried by the network device is each RSRP threshold in the second RSRP threshold set.
在一些可能的实现方式中,网络设备可以在RSRP指示信息中携带上述第二RSRP阈值集合中的RSRP阈值相对于第一RSRP阈值集合中的RSRP阈值的调整量,而网络设备发送前述调整量可以采用以下多种方式:In some possible implementations, the network device may carry in the RSRP indication information the adjustment amount of the RSRP threshold in the second RSRP threshold set with respect to the RSRP threshold in the first RSRP threshold set, and the network device may send the adjustment amount. Use the following methods:
第一种方式,网络设备发送一个比例因子,通信设备根据该比例因子和第一RSRP阈值集合中的RSRP阈值得到第二RSRP阈值集合中的RSRP阈值。例如,比例因子取值集合为
Figure PCTCN2019098409-appb-000009
假设第一RSRP阈值集合中的RSRP阈值为-6.3dB、当前网络设备发送的比例因子为
Figure PCTCN2019098409-appb-000010
则通信设备可以得到调整量为
Figure PCTCN2019098409-appb-000011
进而可以得到第二RSRP阈值集合中的RSRP阈值为-6.3dB+1.575dB=-4.725dB。
In the first manner, the network device sends a scale factor, and the communication device obtains the RSRP threshold in the second RSRP threshold set according to the scale factor and the RSRP threshold in the first RSRP threshold set. For example, the scale factor value set is
Figure PCTCN2019098409-appb-000009
Assume that the RSRP threshold in the first RSRP threshold set is -6.3dB, and the scale factor sent by the current network device is
Figure PCTCN2019098409-appb-000010
Then the communication equipment can be adjusted as
Figure PCTCN2019098409-appb-000011
Furthermore, it can be obtained that the RSRP threshold in the second RSRP threshold set is -6.3dB+1.575dB=-4.725dB.
第二种方式,网络设备发送的调整量取值于一个集合。例如,调整量取值集合为{±8,±6,±4,±2},假设第一RSRP阈值集合中的RSRP阈值为-6.3dB、当前网络设备发送的调整量为2dB,则通信设备可以得到第二RSRP阈值集合中的RSRP阈值为-6.3dB+2dB=-4.3dB。In the second way, the adjustment value sent by the network device is set in a set. For example, the adjustment value set is {±8,±6,±4,±2}, assuming that the RSRP threshold in the first RSRP threshold set is -6.3dB and the adjustment amount sent by the current network device is 2dB, then the communication device It can be obtained that the RSRP threshold in the second RSRP threshold set is -6.3dB+2dB=-4.3dB.
第三种方式,网络设备发送的调整量取值于多个集合,各集合的取值范围和/或量化精度不完全相同。例如,调整量取值集合有2个,分别为{±12,±10,±8,±6,±4,±2,±1}和{±1,±0.5},网络设备可以发送指示信息告知当前发送的调整量取值于哪一个集合,或者通信设备根据提前约定好的规则判断当前发送的调整量取值于哪一个集合,例如约定规则可以是:当通信设备的TA值小于某一阈值时,使用集合{±12,±10,±8,±6,±4,±2,±1};否则, 使用集合{±1,±0.5}。In the third method, the adjustment value sent by the network device is in multiple sets, and the value range and/or quantization accuracy of each set are not completely the same. For example, there are two sets of adjustment values, namely {±12,±10,±8,±6,±4,±2,±1} and {±1,±0.5}, and the network device can send instructions Inform which set the currently sent adjustment value is in, or the communication device judges which set the currently sent adjustment value is in according to a pre-agreed rule. For example, the agreed rule can be: when the TA value of the communication device is less than a certain set For threshold, use set {±12,±10,±8,±6,±4,±2,±1}; otherwise, use set {±1,±0.5}.
第四种方式,当网络设备发送的调整量个数大于1个时,每个调整量可以取值于不同集合,各集合的取值范围和/或量化精度不完全相同。例如,当前网络设备发送的调整量个数为2个,第一个调整量的取值集合可以是{±2,±1,±0.5,±0.25},第二个调整量的取值集合可以是{±8,±6,±4,±2}。In the fourth way, when the number of adjustments sent by the network device is greater than one, each adjustment can be in different sets, and the value range and/or quantization accuracy of each set are not completely the same. For example, the number of adjustments sent by the current network device is 2, the value set of the first adjustment can be {±2,±1,±0.5,±0.25}, and the value set of the second adjustment can be It is {±8,±6,±4,±2}.
在一种可能的实现方式中,网络设备在满足设定条件集合时,才向通信设备发送RSRP指示信息;其中,设定条件集合包括以下至少一个条件:In a possible implementation manner, the network device sends RSRP indication information to the communication device only when the set condition set is met; wherein the set condition set includes at least one of the following conditions:
(1)通信设备到当前服务小区的基站的距离小于第一阈值;(1) The distance from the communication device to the base station of the current serving cell is less than the first threshold;
(2)第二TA小于第二阈值;(2) The second TA is less than the second threshold;
(3)通信设备的RSRP大于第三阈值;(3) The RSRP of the communication device is greater than the third threshold;
(4)第二RSRP阈值集合中有至少一个RSRP阈值的绝对值大于第四阈值;(4) The absolute value of at least one RSRP threshold in the second RSRP threshold set is greater than the fourth threshold;
(5)第二RSRP阈值集合中有两个RSRP阈值的绝对值分别大于第五阈值及第六阈值。(5) The absolute values of two RSRP thresholds in the second RSRP threshold set are respectively greater than the fifth threshold and the sixth threshold.
需要说明的是,上述条件集合中的小于和/或大于的判定条件中也可以根据实际设定的阈值改为小于或等于、大于或等于,本申请对此不做具体限定。例如,上述设定条件集合也可以是:It should be noted that the judgment conditions of less than and/or greater in the above condition set can also be changed to less than or equal to, greater than or equal to, according to the actually set threshold, which is not specifically limited in this application. For example, the above set of conditions can also be:
(1)通信设备到当前服务小区的基站的距离小于或等于第七阈值;(1) The distance from the communication device to the base station of the current serving cell is less than or equal to the seventh threshold;
(2)第二TA小于或等于第八阈值;(2) The second TA is less than or equal to the eighth threshold;
(3)通信设备的RSRP大于或等于第九阈值;(3) The RSRP of the communication device is greater than or equal to the ninth threshold;
(4)第二RSRP阈值集合中有至少一个RSRP阈值的绝对值大于或等于第十阈值;(4) The absolute value of at least one RSRP threshold in the second RSRP threshold set is greater than or equal to the tenth threshold;
(5)第二RSRP阈值集合中有两个RSRP阈值的绝对值分别大于或等于第十一阈值及第十二阈值。(5) The absolute values of two RSRP thresholds in the second RSRP threshold set are greater than or equal to the eleventh threshold and the twelfth threshold, respectively.
与上述情况反之,当通信设备距离当前服务小区的基站较远时,RSRP阈值集合中的RSRP阈值变化量小,此时网络设备可能不需要更新RSRP阈值集合。例如,本申请可以在满足设定条件集合时,即(1)通信设备到当前服务小区的基站的距离大于第一阈值;(2)第二TA大于第二阈值;(3)通信设备的RSRP小于第三阈值;(4)第二RSRP阈值集合中有至少一个RSRP阈值的绝对值小于第四阈值;(5)第二RSRP阈值集合中有两个RSRP阈值的绝对值分别小于第五阈值及第六阈值,网络设备不更新RSRP阈值集合,也无需向通信设备发送RSRP指示信息。Contrary to the above situation, when the communication device is far from the base station of the current serving cell, the RSRP threshold change in the RSRP threshold set is small, and the network device may not need to update the RSRP threshold set at this time. For example, the present application may meet the set condition set, that is, (1) the distance between the communication device and the base station of the current serving cell is greater than the first threshold; (2) the second TA is greater than the second threshold; (3) the RSRP of the communication device Less than the third threshold; (4) the absolute value of at least one RSRP threshold in the second RSRP threshold set is less than the fourth threshold; (5) the absolute value of two RSRP thresholds in the second RSRP threshold set is less than the fifth threshold and The sixth threshold, the network device does not update the RSRP threshold set, nor does it need to send RSRP indication information to the communication device.
综上所述,本申请中网络设备可以在满足一定条件的情况下,才向通信设备发送RSRP指示信息。In summary, the network device in this application can only send RSRP indication information to the communication device when certain conditions are met.
步骤205、通信设备根据RSRP指示信息确定第二RSRP阈值集合。Step 205: The communication device determines a second RSRP threshold set according to the RSRP indication information.
如果RSRP指示信息包括第二RSRP阈值集合中的每个RSRP阈值相对于第一RSRP阈值集合中的每个RSRP阈值的调整量,则通信设备根据前述调整量结合第一RSRP阈值集合中的每个RSRP阈值计算得到第二RSRP阈值集合中的每个RSRP阈值;如果RSRP指示信息包括第二RSRP阈值集合中的每个RSRP阈值通信设备,则通信设备直接获取第二RSRP阈值集合中的每个RSRP阈值。If the RSRP indication information includes the adjustment amount of each RSRP threshold in the second RSRP threshold set with respect to each RSRP threshold in the first RSRP threshold set, the communication device combines each of the RSRP threshold sets in accordance with the foregoing adjustment amount. The RSRP threshold is calculated to obtain each RSRP threshold in the second RSRP threshold set; if the RSRP indication information includes each RSRP threshold communication device in the second RSRP threshold set, the communication device directly obtains each RSRP in the second RSRP threshold set Threshold.
通信设备在确定第二RSRP阈值集合之后,就可以根据第二RSRP阈值集合中的一个或多个RSRP阈值判断第二TA是否有效。示例性的:After determining the second RSRP threshold set, the communication device can determine whether the second TA is valid according to one or more RSRP thresholds in the second RSRP threshold set. Exemplary:
若第二RSRP阈值集合中包括一个RSRP阈值NRSRP threshold,则通信设备在满足|NRSRP change|≤NRSRP threshold时,认为第二TA有效,其中,NRSRP change=NRSRP now-NRSRP refIf the second RSRP threshold set includes an RSRP threshold NRSRP threshold , the communication device considers the second TA valid when |NRSRP change |≤NRSRP threshold , where NRSRP change = NRSRP now- NRSRP ref .
若第二RSRP阈值集合中包括两个RSRP阈值NRSRP threshold1和NRSRP threshold2,则通信设备在满足NRSRP threshold1≤NRSRP change≤NRSRP threshold2时,认为第二TA有效。 If the second RSRP threshold set includes two RSRP thresholds NRSRP threshold1 and NRSRP threshold2 , the communication device considers that the second TA is valid when NRSRP threshold1 ≤ NRSRP change ≤ NRSRP threshold2 is satisfied.
本实施例,网络设备根据第一信息给通信设备重新配置与更新后的TA相匹配的RSRP阈值集合,从而通信设备能够基于新的RSRP阈值集合判断更新后的TA是否有效,该判断结果适应于通信设备状态的改变。针对更新后的TA有效的情况,本实施例的方案使得该通信设备能够尽可能地使用上行免调度传输,从而可以尽可能地降低了通信设备的功耗和网络设备的资源开销。针对更新后的TA失效的情况,本实施例的方案使得该通信设备在此情况下改用传统的数据传输方式进行数据传输,尽可能地减少了该通信设备对其他通信设备的干扰,也减少了网络设备对该通信设备不必要的数据解调。In this embodiment, the network device reconfigures the RSRP threshold set matching the updated TA for the communication device according to the first information, so that the communication device can determine whether the updated TA is valid based on the new RSRP threshold set, and the determination result is adapted to Changes in the state of communication equipment. In view of the fact that the updated TA is valid, the solution of this embodiment enables the communication device to use uplink scheduling-free transmission as much as possible, thereby reducing the power consumption of the communication device and the resource overhead of the network device as much as possible. In view of the failure of the updated TA, the solution of this embodiment causes the communication device to switch to the traditional data transmission method for data transmission in this case, which reduces the interference of the communication device to other communication devices as much as possible, and also reduces The network device demodulates unnecessary data from the communication device.
