Description
本发明涉及通信领域,具体而言,涉及一种随机接入无线网络临时标识(RA-RNTI,Random Access Radio Network Temporary Identity)的配置方法及装置。The present invention relates to the field of communications, and in particular, to a method and an apparatus for configuring a Random Access Radio Network Temporary Identity (RA-RNTI).
机器间(M2M,Machine to Machine)通信是第五代移动通信技术(5G,5th Generation)目前研究的一个重要课题,也是未来无线通信的一个重要应用领域。在M2M课题里,针对终端的低成本和低吞吐量特性,3GPP提出了窄带物联网(NB-IoT,Narow Band Internet of Things)系统的研究子课题,目标是在200KHz的频带内构建一个和长期演进(LTE,Long-Term Evolution)相似的系统,为低成本终端提供低吞吐量的无线通讯服务。下行仍然采用正交频分多址(OFDMA,Orthogonal Frequency Division Multiple Access)技术,上行采用单载波频分多址(SC-FDMA,Single-Carrier Frequency Division Multiple Access)技术,并尽量重用或简化LTE系统中已有的功能模块。子载波宽度除了沿用LTE系统15KHz的子载波宽度外,上行增加3.75KHz的子载波宽度以进一步增强机器终端上行的覆盖能力。当前,相关的技术标准正在3GPP国际标准化组织内进行研究。M2M (Machine to Machine) communication is an important topic of the fifth generation of mobile communication technology (5G, 5th Generation), and an important application field for wireless communication in the future. In the M2M project, 3GPP proposed a research sub-project of the NB-IoT (Narow Band Internet of Things) system for the low-cost and low-throughput characteristics of the terminal. The goal is to build a long-term and long-term band in the 200 kHz band. A similar system (LTE, Long-Term Evolution) provides low-throughput wireless communication services for low-cost terminals. The downlink still uses the Orthogonal Frequency Division Multiple Access (OFDMA) technology, and the uplink uses the Single-Carrier Frequency Division Multiple Access (SC-FDMA) technology, and reuses or simplifies the LTE system as much as possible. The existing functional modules. The subcarrier width increases the subcarrier width of 3.75 KHz in the uplink in addition to the subcarrier width of 15 KHz in the LTE system to further enhance the coverage capability of the uplink of the machine terminal. Currently, relevant technical standards are being studied within the 3GPP International Organization for Standardization.
在传统LTE系统中,不同的随机接入信道是使用不同的随机接入无线网络临时标识(RA-RNTI,Random Access Radio Network Temporary Identity)进行区别的。用户终端使用和发送随机接入前导的物理随机接入信道(PRACH,Physical Random Access Channel)所对应的RA-RNTI在后续的随机接入响应窗内进行随机接入响应(RAR,Random Access Response)的接收。这个过程中,用户终端使用的RA-RNTI是根据发送随机接入前导的PRACH所在的第一个子帧号(0~9),发送随机接入前导的PRACH在频域上的索引(0~5)进行计算得到的。可见,传统的的RA-RNTI计算方法是以发送随机接入前导的PARCH所占的第一个子帧的子帧号和PARCH的频率索引号为参数进行计算的,最多支持一个10ms帧范围内的物理随机接入信道(PRACH,Physical Random Access Channel)的识别。In a conventional LTE system, different random access channels are distinguished by using different Random Access Radio Network Temporary Identity (RA-RNTI). The user terminal uses the RA-RNTI corresponding to the physical random access channel (PRACH) of the random access preamble to perform a random access response (RAR, Random Access Response) in the subsequent random access response window. Reception. In this process, the RA-RNTI used by the user equipment is based on the first subframe number (0 to 9) where the PRACH of the random access preamble is located, and the index of the PRACH in the frequency domain of the random access preamble is transmitted (0 to 5) Calculated. It can be seen that the traditional RA-RNTI calculation method is calculated by using the subframe number of the first subframe occupied by the PARCH that transmits the random access preamble and the frequency index number of the PARCH as parameters, and supports a maximum of 10 ms frame range. Identification of a Physical Random Access Channel (PRACH).
由于不同用户可能在相同的PRACH发送不同的随机接入前导,一个RAR消息中经常会包含多个RAR单元,每个RAR单元包含有一个随机接入前导标识(RAPID,Random Access Preamble Identity)用来指示该RAR单元的目标用户。A different RAR message is often included in a RAR message, and each RAR unit includes a random access preamble identity (RAPID). Indicates the target user of the RAR unit.
综上所述,传统LTE系统中,用户在发送随机接入前导之后,必须在规定的RAR窗口内检测所有的PDCCH。且如果在某个PDCCH中使用PRACH所对应的RA-RNTI成功解码了某个DCI信息后,还需要按照该DCI信息接收RAR消息中的所有RAR单元。最后才根据RAR单元的RAPID找到自己的RAR单元。这个过程中,用户设备耗能很多。由于NB IoT系统希望用户侧电池的使用寿命在10年以上,省电的设计就显得尤为重要。
In summary, in the conventional LTE system, after transmitting a random access preamble, the user must detect all PDCCHs in a prescribed RAR window. And if a certain DCI information is successfully decoded by using the RA-RNTI corresponding to the PRACH in a certain PDCCH, all RAR units in the RAR message need to be received according to the DCI information. Finally, I find my RAR unit based on the RAPID of the RAR unit. In this process, user equipment consumes a lot of energy. Since the NB IoT system expects the life of the user-side battery to be more than 10 years, the power-saving design is particularly important.
针对相关技术中,用户设备必须解析出包括了多个RAR单元的RAR信息才能获取到自身需要的RAR单元进而导致用户设备耗电量很大的问题,尚未提出有效的解决方案。For the related art, the user equipment must parse the RAR information including multiple RAR units to obtain the RAR unit that is needed by itself, and the user equipment consumes a large amount of power. No effective solution has been proposed.

The above technical means is used to solve the related art, and the user equipment must parse out more The RAR information of the RAR unit can obtain the RAR unit that is required by the RAR unit, and the user equipment consumes a large amount of power. The technical solution of the embodiment of the present invention reduces the user's consumption by optimizing the configuration and process of the random access. Electricity to support longer battery life.
从上述步骤S102和步骤S202均可以看出,基站为所有随机接入前导,配置至少两个不同的RA-RNTI,即基站为一个或多个随机接入前导规定一个相同的RA-RNTI,通过调节共享相同RA-RNTI的随机接入前导的个数可以控制RAR消息中有效消息的比例。这种情况下,虽然每个RAR单元中还是需要进行RAPID的指示,但其所占比特数还是可以大大减小。It can be seen from the foregoing steps S102 and S202 that the base station configures at least two different RA-RNTIs for all random access preambles, that is, the base station specifies one and the same RA-RNTI for one or more random access preambles. Adjusting the number of random access preambles sharing the same RA-RNTI can control the proportion of valid messages in the RAR message. In this case, although the indication of the RAPID is still required in each RAR unit, the number of bits occupied by it can be greatly reduced.
对于上述技术方案,基站为随机接入前导配置的RA-RNTI可以包括多种配置方式,以下结合一示例解释说明上述配置方式,以及用户设备如何根据PRACH上发送的随机接入前导选择RA-RNTI。For the foregoing technical solution, the RA-RNTI configured by the base station for the random access preamble may include multiple configuration manners. The following describes the foregoing configuration manner, and how the user equipment selects the RA-RNTI according to the random access preamble sent on the PRACH. .
当一个PRACH包括五个随机接入前导,可以配置前两个随机接入前导对应第一RA-RNTI,后三个随机接入前导对应第二RA-RNTI,基站会将上述对应关系告知用户设备,具体可以是基站通过广播消息或者指定信令方式告知用户设备,用户设备接收到随机接入前导后,根据基站发送的对应关系,获取接收到的随机接入前导对应的RA-RNTI。When a PRACH includes five random access preambles, the first two random access preambles may be configured to correspond to the first RA-RNTI, and the last three random access preambles correspond to the second RA-RNTI, and the base station may notify the user equipment of the corresponding relationship. Specifically, the base station may notify the user equipment by using a broadcast message or a specified signaling manner, and after receiving the random access preamble, the user equipment acquires the RA-RNTI corresponding to the received random access preamble according to the corresponding relationship sent by the base station.
在本发明实施例中,还存在多种配置方式,例如,五个随机接入前导中前两个随机接入前导对应第一RA-RNTI,第三个和第四个对应第二RA-RNTI,第五个对应第三RA-RNTI,基
站通过广播消息或者指定信令方式将这种对应关系发送至用户设备,还可以是7个随机接入前导中前三个对应第一RA-RNTI,后四个对应第二RA-RNTI,基站通过广播消息或者指定信令方式将这种对应关系发送至用户设备,需要说明的是,上述示例仅用于解释说明本发明实施例的技术方案,并不用于限定本发明实施例。In the embodiment of the present invention, there are multiple configurations, for example, the first two random access preambles of the five random access preambles correspond to the first RA-RNTI, and the third and fourth corresponding second RA-RNTIs. The fifth corresponds to the third RA-RNTI, the base
The station sends the corresponding relationship to the user equipment by using a broadcast message or a specified signaling manner, and may also be the first three RA-RNTIs corresponding to the first three of the seven random access preambles, and the second RA-RNTI corresponding to the second four base stations. The corresponding relationship is sent to the user equipment by means of a broadcast message or a specified signaling manner. It is to be noted that the above-mentioned examples are only used to explain the technical solutions of the embodiments of the present invention, and are not intended to limit the embodiments of the present invention.
为了更好的实现减少耗电的技术效果,上述配置信息用于为同一个PRACH上的所有随机接入前导分配各不相同的RA-RNTI,即PRACH上的所有随机接入前导分配的是两两各不相同的RA-RNTI,能够最大限度的节省耗电。In order to better achieve the technical effect of reducing power consumption, the foregoing configuration information is used to allocate different RA-RNTIs for all random access preambles on the same PRACH, that is, all random access preambles on the PRACH are allocated two. Two different RA-RNTIs can save power.
当然,由于随机接入前导的RA-RNTI各不相同,不同用户的RAR信息就可以完全区别开来,每个RAR信息中只包含用户需要的RAR单元,RAR信息中可以不包括RAPID来继续指示RAR单元,即RAR信息的比特数也会大大减少,因此,基站可以在PDCCH上发送RAR信息,这时,可以直接使用已发送的随机接入前导所对应的RA-RNTI对该RAR消息进行加扰。Certainly, the RAR information of different users may be completely distinguished because the RA-RNTIs of the random access preambles are different. Each RAR information only includes RAR units required by the user, and the RAR information may not include the RAPID to continue indication. The RAR unit, that is, the number of bits of the RAR information is also greatly reduced. Therefore, the base station can transmit the RAR information on the PDCCH. In this case, the RAR message can be directly added by using the RA-RNTI corresponding to the transmitted random access preamble. Disturb.
对于上述配置信息的发送方式,本发明实施例的可选示例中提供了两种实现方式:携带在系统消息广播消息发送;通过指定标准协议约定。For the manner of sending the foregoing configuration information, two implementation manners are provided in the optional example of the embodiment of the present invention: carrying a message broadcast message in the system; and specifying a standard protocol.
可选地,上述方法还包括:如果用户设备在指定时间内未接收到RAR信息,用户设备接收基站通过至少以下方式之一传递的回退指示BI信息:通过系统消息模块SIB发送BI信息;通过物理下行控制信道PDCCH发送BI信息,其中,可以通过PDCCH中的公共搜索空间发送BI信息,在可选示例中,在PDCCH中发送BI信息,该BI信息通过指定的小区无线网络临时标识C-RNTI进行扰码。Optionally, the method further includes: if the user equipment does not receive the RAR information within the specified time, the user equipment receives the back-off indication BI information that is sent by the base station by using at least one of the following manners: sending the BI information by using the system message module SIB; The physical downlink control channel PDCCH transmits BI information, wherein the BI information may be transmitted through a common search space in the PDCCH. In an optional example, BI information is transmitted in the PDCCH, the BI information temporarily identifying the C-RNTI through the designated cell radio network Perform scrambling code.
当用户设备侧进行了基站所规定的最大次数的随机接入重发并始终无法收到相应的RAR信息之后,用户设备判定当前随机接入过程失败,此处,用户设备侧还可以执行以下技术方案:根据至少以下情况判断是否启动下一轮的随机接入过程:定时器时间是否到达;参考信号接收功率RSRP的变化情况;当前PRACH信道的负荷状态,进一步地,上述定时器的时长通过至少以下方式之一参数确定:基站发送的配置信息;用户设备随机接入失败的次数。After the user equipment side performs the maximum number of random access retransmissions specified by the base station and cannot receive the corresponding RAR information, the user equipment determines that the current random access procedure fails. Here, the user equipment side can also perform the following technologies. Solution: judging whether to start the next round of random access procedure according to at least the following conditions: whether the timer time is reached; the change of the reference signal receiving power RSRP; the load status of the current PRACH channel, and further, the duration of the foregoing timer passes at least One of the following parameters determines the configuration information sent by the base station; the number of times the user equipment fails to access the random access.
综上所述,本发明实施例提出的技术方案:基于随机接入前导的RA-NTI配置方法,即基站为同一个PRACH中发送的不同随机接入前导规定不同的RA-RNTI值,用户设备在发送一个随机接入前导之后,就用相应的RA-RNTI进行后续RAR的接收。这样,不同用户设备的RAR消息就可以完全分开。一个用户设备只需要接收自己的RAR消息,而不需要接收其他用户设备的RAR消息。并且,由于每个RAR消息只包含一个RAR单元,RAPID可以不用再进行指示。In summary, the technical solution proposed by the embodiment of the present invention is: a RA-NTI configuration method based on a random access preamble, that is, a base station specifies different RA-RNTI values for different random access preambles transmitted in the same PRACH, and the user equipment After transmitting a random access preamble, subsequent RAR reception is performed with the corresponding RA-RNTI. In this way, the RAR messages of different user equipments can be completely separated. A user equipment only needs to receive its own RAR message without receiving RAR messages of other user equipments. Moreover, since each RAR message contains only one RAR unit, the RAPID can be omitted.
本发明实施例对上述技术方案的进一步改进在于,基站可以在系统广播中指示RA-RNTI配置方法是传统的基于PRACH的处理流程的还是基于随机接入前导的处理流程,用户设备根据收到的指示进行具体的随机接入操作。如果RA-RNTI配置方法指示是基于随机接入前导的,则按本发明实施例的方法进行后续RA操作。否则,按传统方法进行后续RA操作。
A further improvement of the foregoing technical solution in the embodiment of the present invention is that the base station can indicate in the system broadcast whether the RA-RNTI configuration method is a traditional PRACH-based processing flow or a random access preamble-based processing flow, and the user equipment receives the Indicates a specific random access operation. If the RA-RNTI configuration method indication is based on a random access preamble, the subsequent RA operation is performed according to the method of the embodiment of the present invention. Otherwise, follow-up RA operations are performed in the traditional way.
当用户设备发送随机接入前导之后,如果没有收到RAR消息,需要接收基站的回退指示BI。通常,在同一个PRACH中发送随机接入前导的用户设备需要接收并使用相同的BI指示进行后续回退操作。为此,本发明实施例还提出了以下几种BI信息传递方法:After the user equipment sends the random access preamble, if the RAR message is not received, the base station's backoff indication BI needs to be received. Generally, a user equipment that transmits a random access preamble in the same PRACH needs to receive and use the same BI indication for subsequent backoff operations. To this end, the embodiments of the present invention also propose the following methods for BI information transmission:
1)将BI信息放到SIB中,如果用户设备在RAR窗中如果无法收到自己的RAR消息,就直接使用SIB中的BI值进行回退后再继续下一次随机接入前导的发送。1) Put the BI information into the SIB. If the user equipment cannot receive its own RAR message in the RAR window, it directly uses the BI value in the SIB to roll back and then resumes the next random access preamble.
2)基站可以在PDCCH中的公共搜索空间发送BI信息。该信息也可以合并在其他公共信息中,基站可以为每个PRACH指定一个专门的RNTI(例如可以称为BI-RNTI)进行PDCCH中BI信息的发送,在一个可选示例中,该BI信息可以位于RAR窗中的最后一个PDCCH中。2) The base station can transmit BI information in a common search space in the PDCCH. The information may also be combined in other public information. The base station may specify a specific RNTI (for example, may be referred to as BI-RNTI) for each PRACH to transmit BI information in the PDCCH. In an optional example, the BI information may be Located in the last PDCCH in the RAR window.
当用户设备进行了基站所规定的最大次数的随机接入重发并始终无法收到相应的RAR信息之后,用户设备判定随机接入失败。用户设备可以启动一个定时器,并在该定时器超时之后重新开始新一轮的随机接入过程,即重新选择PRACH,并进行随机接入前导的发送和重发。可选的,该定时器所配置的时长可以根据基站发送的信息决定;该定时器的时长可以根据标准协议规定进行配置;该定时器所配置的时长可以根据随机接入失败次数由用户设备进行动态配置。After the user equipment performs the maximum number of random access retransmissions specified by the base station and cannot receive the corresponding RAR information at all times, the user equipment determines that the random access fails. The user equipment can start a timer and restart a new round of random access procedure after the timer expires, that is, reselect the PRACH, and perform random access preamble transmission and retransmission. Optionally, the duration of the timer may be determined according to information sent by the base station; the duration of the timer may be configured according to a standard protocol; the duration configured by the timer may be performed by the user equipment according to the number of random access failures. Dynamic configuration.
可选的,用户设备也可以继续监测或周期性的监测所接收的基站信号RSRP的变化,并根据基站信号RSRP的变化决定是否重新开始新一轮的随机接入过程,即重新选择PRACH,并进行随机接入前导的发送和重发。当然,用户设备还可以根据当前信道的负荷状态决定是否重新开始新一轮的随机接入过程。Optionally, the user equipment may continue to monitor or periodically monitor the received RSRP change of the base station signal, and determine whether to restart a new round of random access procedure according to the change of the base station signal RSRP, that is, reselect the PRACH, and The transmission and retransmission of the random access preamble is performed. Of course, the user equipment can also decide whether to restart a new round of random access procedure according to the load status of the current channel.
本发明实施例的上述技术方案:包括基于随机接入前导的RA-RNTI配置和相应的BI通知方法。由于用户设备只需要接收自己的RAR单元,而无需接收使用同一PRACH的其他用户设备的RAR单元,所以可以减小耗电,延长电池寿命。其次,基站可以不用为RAR单元进行RAPID的指示,减少了需要传递的信息,这进一步减小了耗电。最后,本发明实施例对BI指示方法进行了优化,以适应所提出的随机接入。The foregoing technical solution of the embodiment of the present invention includes: a RA-RNTI configuration based on a random access preamble and a corresponding BI notification method. Since the user equipment only needs to receive its own RAR unit without receiving the RAR unit of other user equipments using the same PRACH, power consumption can be reduced and battery life can be prolonged. Secondly, the base station can reduce the need to transmit information without performing an indication of the RAPID for the RAR unit, which further reduces power consumption. Finally, the embodiment of the present invention optimizes the BI indication method to accommodate the proposed random access.
