網路設備在發送RAR消息之前,首先會根據接收到的隨機接入請求消息確定RA-RNTI。相應地,終端設備根據發送的隨機接入請求消息確定RA-RNTI。換句話說,網路設備和終端設備分別確定隨機接入請求消息對應的RA-RNTI。首先介紹現有技術中確定RA-RNTI的方式。Before sending the RAR message, the network device first determines the RA-RNTI according to the received random access request message. Correspondingly, the terminal device determines the RA-RNTI according to the sent random access request message. In other words, the network device and the terminal device respectively determine the RA-RNTI corresponding to the random access request message. First, the method of determining the RA-RNTI in the prior art is introduced.
網路設備和終端設備根據隨機接入請求消息佔用的第一個子幀(subframe)的編號和該第一個子幀裡隨機接入請求消息佔用的頻域位置的編號,確定RA-RNTI。The network device and the terminal device determine the RA-RNTI according to the number of the first subframe occupied by the random access request message and the number of the frequency domain position occupied by the random access request message in the first subframe.
具體地,網路設備和終端設備可以根據公式(1)確定RA-RNTI。Specifically, the network device and the terminal device may determine the RA-RNTI according to formula (1).
RA-RNTI = 1+t_id+10f_id (1)RA-RNTI = 1+t_id+10f_id (1)
其中,t_id為隨機接入請求消息佔用的第一個子幀的編號,f_id為在該第一個子幀裡隨機接入請求消息佔用的頻域位置的編號。Where t_id is the number of the first subframe occupied by the random access request message, and f_id is the number of the frequency domain position occupied by the random access request message in the first subframe.
網路設備接收到隨機接入請求消息之後,根據公式(1)確定RA-RNTI,並根據該RA-RNTI發送RAR消息,相應地,終端設備確定該RA-RNTI,並根據該RA-RNTI監聽屬於自己的RAR消息。該方式會增加終端設備獲取RAR消息的複雜度。After receiving the random access request message, the network device determines the RA-RNTI according to formula (1), and sends a RAR message according to the RA-RNTI. Accordingly, the terminal device determines the RA-RNTI and monitors according to the RA-RNTI Your own RAR message. This method will increase the complexity of the terminal device acquiring RAR messages.
例如,在多波束(Multi-beam)系統中,為了提高終端設備發送隨機接入請求消息的成功率,終端設備可以通過不同的波束向網路設備發送隨機接入請求消息。終端設備在不同的波束發送隨機接入請求消息時,每個波束對應的時域資源的訊息不同(例如,對應的第一個子幀的編號不同)。此時,終端設備在監聽屬於自己的RAR消息時需要嘗試多個RA-RNTI,導致終端設備獲取RAR的複雜度較高。For example, in a multi-beam system, in order to improve the success rate of the terminal device sending the random access request message, the terminal device can send the random access request message to the network device through different beams. When the terminal device sends a random access request message on different beams, the information of the time domain resource corresponding to each beam is different (for example, the number of the corresponding first subframe is different). At this time, the terminal device needs to try multiple RA-RNTIs when listening to its own RAR message, resulting in a higher complexity for the terminal device to obtain RAR.
又例如,為了提高終端設備發送隨機接入前導碼的成功率,終端設備可以使用頻分複用的方式在同一個時域資源上發送多個隨機接入請求消息(多個隨機接入請求消息攜帶的隨機接入前導碼可以相同也可以不同)。此時,終端設備在監聽屬於該第一終端設備的RAR消息時也需要嘗試多個RA-RNTI,導致終端設備獲取RAR消息的複雜度較高。For another example, in order to improve the success rate of the terminal device sending a random access preamble, the terminal device may use frequency division multiplexing to send multiple random access request messages (multiple random access request messages) on the same time domain resource The random access preamble carried may be the same or different). At this time, the terminal device also needs to try multiple RA-RNTIs when listening to the RAR message belonging to the first terminal device, resulting in a higher complexity for the terminal device to obtain the RAR message.
為了降低終端設備獲取RAR消息的複雜度,可以採用以下方式確定RA-RNTI。In order to reduce the complexity of the terminal device acquiring the RAR message, the RA-RNTI can be determined in the following manner.
方式一、method one,
根據隨機接入請求消息佔用的資源的第一資源訊息確定RA-RNTI。其中,該第一資源訊息用於指示該隨機接入請求消息佔用的頻域資源或時域資源。The RA-RNTI is determined according to the first resource message of the resources occupied by the random access request message. The first resource message is used to indicate the frequency domain resource or time domain resource occupied by the random access request message.
例如,網路設備和終端設備可以根據公式(2)確定RA-RNTI。For example, network equipment and terminal equipment may determine RA-RNTI according to formula (2).
RA-RNTI = t_id+A (2)RA-RNTI = t_id+A (2)
其中,t_id為隨機接入請求消息佔用的第一個子幀的編號;A為調整參數。Where t_id is the number of the first subframe occupied by the random access request message; A is the adjustment parameter.
又例如,網路設備和終端設備可以根據公式(3)確定RA-RNTI。For another example, the network device and the terminal device may determine RA-RNTI according to formula (3).
RA-RNTI=10f_id+B (3)RA-RNTI=10f_id+B (3)
其中,f_id 為在隨機接入請求消息佔用的第一個子幀裡該隨機接入請求消息佔用的頻域位置編號,B為調整參數。Where, f_id is the frequency domain position number occupied by the random access request message in the first subframe occupied by the random access request message, and B is the adjustment parameter.
該方式確定RA-RNTI,可以降低終端設備獲取RAR消息的複雜度,但是,現有技術中的確定屬於自己的RAR消息具有局限性,若將方式一與現有技術中確定屬於自己的RAR消息的方式結合,容易導致終端設備判斷出錯。This method of determining the RA-RNTI can reduce the complexity of the terminal device acquiring the RAR message. However, the determination of the RAR message belonging to itself in the prior art has limitations. If the method 1 is the same as the method of determining the RAR message belonging to itself in the prior art Combined, it is easy to cause errors in terminal device judgment.
例如,在第一資源訊息用於指示隨機接入請求消息佔用的頻域資源的情況下,網路設備和終端設備根據第一資源訊息確定RA-RNTI,若第一終端設備和第二終端設備均佔用頻域資源C發送隨機接入請求消息,且第一終端設備和第二終端設備發送的隨機接入請求消息均包括隨機接入前導碼D,網路設備先根據第二終端設備發送的隨機接入請求消息發送RAR消息(記為第二RAR消息),第一終端設備和第二終端設備均監聽到該第二RAR消息,該第二RAR消息攜帶隨機接入前導碼D的訊息(例如,隨機接入前導碼D的索引)。若仍採用現有技術中確定RAR消息的方式(即僅根據隨機接入前導碼的索引確定屬於自己的RAR消息),第一終端設備會誤認為該第二RAR消息為屬於自己的RAR消息,並使用該第二RAR消息中的訊息進行相關操作,導致第一終端設備處理出錯。For example, in the case where the first resource message is used to indicate the frequency domain resource occupied by the random access request message, the network device and the terminal device determine RA-RNTI according to the first resource message, if the first terminal device and the second terminal device Both occupy frequency domain resources C and send random access request messages, and the random access request messages sent by the first terminal device and the second terminal device both include a random access preamble D, and the network device first sends The random access request message sends a RAR message (recorded as a second RAR message), and both the first terminal device and the second terminal device listen to the second RAR message, and the second RAR message carries a random access preamble D message ( For example, the index of the random access preamble D). If the method of determining the RAR message in the prior art is still used (that is, only the RAR message belonging to itself is determined according to the index of the random access preamble), the first terminal device may mistakenly consider the second RAR message to be its own RAR message, and Use the information in the second RAR message to perform related operations, resulting in an error in the processing of the first terminal device.
同理,在第一資源訊息用於指示隨機接入請求消息佔用的時域資源的情況下,由於現有技術中的確定屬於自己的RAR消息具有局限性,也容易導致終端設備判斷出錯。Similarly, in the case where the first resource message is used to indicate the time-domain resource occupied by the random access request message, due to the limitation of the RAR message that determines that it belongs to itself in the prior art, it is also easy to cause an error in the judgment of the terminal device.
方式二、Method two
根據隨機接入請求消息佔用的資源的第一資源訊息確定RA-RNTI。其中,該第一資源訊息用於指示該隨機接入請求消息佔用的頻域資源和時域資源,且方式二中第一資源訊息指示的時域資源的細微性較大。The RA-RNTI is determined according to the first resource message of the resources occupied by the random access request message. Wherein, the first resource message is used to indicate the frequency domain resource and the time domain resource occupied by the random access request message, and the time domain resource indicated by the first resource message in mode 2 is more nuanced.
例如,在方式二中,網路設備和終端設備根據隨機接入請求消息佔用的無線幀的訊息(例如,佔用的第一個無線幀的編號)確定RA-RNTI。For example, in the second method, the network device and the terminal device determine the RA-RNTI according to the information of the radio frame occupied by the random access request message (for example, the number of the first radio frame occupied).
該方法能夠平衡終端設備接收RAR消息的複雜度以及終端設備確定屬於自己的RAR的次數。但是,由於現有技術中的確定屬於自己的RAR消息具有局限性,若將方式二與現有技術中確定屬於自己的RAR消息的方式結合,容易導致終端設備判斷出錯,具體說明可以參見上文的相關描述,為了簡潔此處不再贅述。This method can balance the complexity of the terminal device receiving the RAR message and the number of times that the terminal device determines its own RAR. However, due to the limitation of determining that the RAR message belongs to you in the prior art, if you combine the second method with the method of determining your own RAR message in the prior art, it is easy to cause an error in the judgment of the terminal device. The description will not be repeated here for brevity.
進一步地,假設多個終端設備佔用相同的子幀和頻域資源發送相同的隨機接入前導碼,該多種終端設備接收到某個終端設備的RAR消息之後,根據該RAR消息攜帶的隨機接入前導碼,會認為該RAR消息屬於自己,並根據該RAR消息進行競爭過程。由於終端設備沒有正確識別屬於自己的RAR消息,會導致終端設備進行無意義的競爭。Further, it is assumed that multiple terminal devices occupy the same subframe and frequency domain resources and send the same random access preamble. After receiving the RAR message of a certain terminal device, the multiple terminal devices according to the random access carried in the RAR message The preamble will consider that the RAR message belongs to itself, and will compete according to the RAR message. Since the terminal device does not correctly identify its own RAR message, it will cause the terminal device to compete meaninglessly.
通過分析可以發現,採用現有技術中僅根據RAR消息中的隨機接入前導碼的索引確定屬於自己的RAR消息具有局限性,不利於終端設備準確地確定屬於自己的RAR消息。Through analysis, it can be found that using the prior art to determine the own RAR message according to the index of the random access preamble in the RAR message has limitations, which is not conducive to the terminal device accurately determining the own RAR message.
有鑑於此,本發明實施例提供一種用於隨機接入的方法,網路設備發送的RAR消息包括前導碼訊息和指示訊息,終端設備可以根據前導碼訊息和指示訊息確定接收到的RAR消息是否屬於自己。該方法具有較高的相容性,有利於終端設備準確地判斷屬於自己的RAR消息。下面詳細說明本發明實施例的用於隨機接入的方法。In view of this, embodiments of the present invention provide a method for random access. The RAR message sent by the network device includes a preamble message and an indication message. The terminal device can determine whether the received RAR message is based on the preamble message and the indication message. belong to myself. This method has high compatibility, which is helpful for the terminal device to accurately judge its own RAR message. The method for random access according to an embodiment of the present invention is described in detail below.

It should be understood that the first terminal device is any terminal device in at least one terminal device, and the "first" is only used for distinguishing descriptions, and should not constitute any limitation to the embodiments of the present invention. Similarly, the second terminal device should not constitute any limitation on the embodiments of the present invention.
如圖2所示,該方法200包括:As shown in FIG. 2, the
S210、第一終端設備向網路設備發送隨機接入請求消息,相應地,網路設備接收第一終端設備發送的隨機接入請求消息,其中,該隨機接入請求消息包括隨機接入前導碼。S210. The first terminal device sends a random access request message to the network device. Correspondingly, the network device receives the random access request message sent by the first terminal device, where the random access request message includes a random access preamble .
可選地,本發明實施例中,第一終端設備可以通過多波束的方式向網路設備發送接入請求消息。Optionally, in the embodiment of the present invention, the first terminal device may send an access request message to the network device in a multi-beam manner.
其中,終端設備在通過多波束的方式發送隨機接入請求消息時,不同的波束的起始子幀的位置可以不同。Wherein, when the terminal device sends the random access request message in a multi-beam manner, the starting subframe positions of different beams may be different.
可選地,本發明實施例中,第一終端設備可以通過一個波束發送隨機接入請求消息之後,等待網路設備發送的RAR消息,如果未等到網路設備發送的RAR消息,採用另一波束發送隨機接入請求消息,並等待網路設備發送的RAR消息,如果接收到網路設備發送的RAR消息,則停止發送隨機接入請求消息,否則,再次選擇波束發送隨機接入請求消息。Optionally, in the embodiment of the present invention, the first terminal device may wait for the RAR message sent by the network device after sending the random access request message through one beam, and if it does not wait for the RAR message sent by the network device, use another beam Send a random access request message and wait for the RAR message sent by the network device. If the RAR message sent by the network device is received, stop sending the random access request message. Otherwise, select the beam again to send the random access request message.
S220、網路設備根據該隨機接入請求消息確定RA-RNTI,相應地,第一終端設備根據該隨機接入請求消息確定RA-RNTI;S220. The network device determines the RA-RNTI according to the random access request message. Accordingly, the first terminal device determines the RA-RNTI according to the random access request message;
S230、網路設備根據RA-RNTI發送RAR消息,相應地,第一終端設備根據RA-RNTI接收網路設備發送的RAR消息,其中,該RAR消息包括指示訊息和前導碼訊息,該前導碼訊息用於指示該隨機接入前導碼;S230. The network device sends a RAR message according to the RA-RNTI. Accordingly, the first terminal device receives the RAR message sent by the network device according to the RA-RNTI. The RAR message includes an indication message and a preamble message. The preamble message Used to indicate the random access preamble;
具體地,網路設備根據RA-RNTI和該隨機接入請求消息發送RAR消息。Specifically, the network device sends a RAR message according to the RA-RNTI and the random access request message.
S240、該第一終端設備根據該指示訊息和該前導碼訊息,確定該RAR消息屬於該第一終端設備。S240. The first terminal device determines that the RAR message belongs to the first terminal device according to the instruction message and the preamble message.
為了便於說明,可以將“第一終端設備發送的隨機接入請求消息”記為“第一請求消息”,將“第一隨機接入請求消息攜帶的隨機接入前導碼”記為“第一前導碼”,將“根據第一請求消息確定的RA-RNTI”記為“第一RA-RNTI”將“網路設備根據第一請求消息發送的RAR消息”記為“第一RAR消息”。For convenience of description, the "random access request message sent by the first terminal device" may be recorded as the "first request message", and the "random access preamble carried in the first random access request message" may be recorded as the "first The "preamble" records "RA-RNTI determined according to the first request message" as "first RA-RNTI" and "RAR message sent by the network device according to the first request message" as "first RAR message".
具體地,第一終端設備需要確定接收到的RAR消息是否屬於該第一終端設備。Specifically, the first terminal device needs to determine whether the received RAR message belongs to the first terminal device.
例如,第一終端設備發送第一請求消息之後,若第一終端設備接收的RAR消息攜帶的指示訊息與第一請求消息相匹配,且該RAR消息攜帶的前導碼訊息指示的隨機接入前導碼與第一前導碼相同,第一終端設備可以確定該RAR消息屬於該第一終端設備。For example, after the first terminal device sends the first request message, if the indication message carried in the RAR message received by the first terminal device matches the first request message, and the random access preamble indicated by the preamble message carried in the RAR message Same as the first preamble, the first terminal device may determine that the RAR message belongs to the first terminal device.
又例如,第一終端設備發送第一請求消息之後,若第一終端設備接收的RAR消息攜帶的指示訊息與第一請求消息不匹配,或該RAR消息攜帶的前導碼訊息指示的隨機接入前導碼與第一前導碼不相同,第一終端設備可以確定該RAR消息不屬於該第一終端設備。For another example, after the first terminal device sends the first request message, if the indication message carried in the RAR message received by the first terminal device does not match the first request message, or the random access preamble indicated by the preamble message carried in the RAR message The code is different from the first preamble, and the first terminal device may determine that the RAR message does not belong to the first terminal device.
與現有技術中終端設備僅根據RAR消息中的隨機接入前導碼的索引確定屬於自己的RAR消息相比,在本發明實施例中,RAR消息不僅攜帶前導碼訊息還攜帶指示訊息,第一終端設備根據RAR消息攜帶的前導碼訊息和指示訊息確定屬於自己的RAR消息,該方法具有較高的相容性,能夠適用于多種應用場景,有利於第一終端設備準確地確定屬於自己的RAR消息。Compared with the prior art where the terminal device determines its own RAR message only based on the index of the random access preamble in the RAR message, in the embodiment of the present invention, the RAR message carries not only the preamble message but also the indication message. The first terminal The device determines its own RAR message according to the preamble message and indication message carried in the RAR message. This method has high compatibility and can be applied to a variety of application scenarios, which is conducive to the first terminal device accurately determining its own RAR message .
可選地,在S240之前,該方法200還可以包括:Optionally, before S240, the
S201、第二終端設備向網路設備發送第二隨機接入請求消息,相應地,網路設備接收該第二隨機接入請求消息,可以將“第二隨機接入請求消息”記為“第二請求消息”;S201. The second terminal device sends a second random access request message to the network device. Correspondingly, the network device receives the second random access request message, and may record the "second random access request message" as "the first Second request message";

Correspondingly, the network device determines the RA-RNTI according to the second request message, and may record "RA-RNTI determined according to the second request message" as "Second RA-RNTI";
S203、網路設備根據該第二RA-RNTI發送第二RAR消息;S203. The network device sends a second RAR message according to the second RA-RNTI;
S204、第二終端設備根據該第二RAR消息攜帶的前導碼訊息和指示訊息,確定該第二RAR消息為屬於自己的RAR消息,該第二終端設備停止監聽屬於自己的RAR消息;S204. The second terminal device determines that the second RAR message is its own RAR message according to the preamble message and the indication message carried in the second RAR message, and the second terminal device stops listening to its own RAR message;
對於第一終端設備而言,網路設備發送第二RAR消息至少可以包括以下兩種情況:For the first terminal device, the network device sending the second RAR message may include at least the following two cases:
情況一、第一RA-RNTI和第二RA-RNTI不相同,第一終端設備無法接收該第二RAR消息。Case 1: The first RA-RNTI and the second RA-RNTI are different, and the first terminal device cannot receive the second RAR message.
情況二、第一RA-RNTI和第二RA-RNTI相同,第一終端設備和第二終端設備均可以接收到該第二RAR消息,該第一終端設備需要根據第二RAR消息中的指示訊息和前導碼訊息確定該第二RAR消息是否屬於該第一終端設備。若該第一終端設備確定該第二RAR消息屬於該第一終端設備,該第一終端設備可以根據該第二RAR消息進行處理;若該第一終端設備確定該第二RAR消息不屬於該第一終端設備,該第一終端設備需要繼續監聽屬於該第一終端設備的RAR消息。Case 2: The first RA-RNTI and the second RA-RNTI are the same, both the first terminal device and the second terminal device can receive the second RAR message, and the first terminal device needs to follow the indication message in the second RAR message And the preamble message determine whether the second RAR message belongs to the first terminal device. If the first terminal device determines that the second RAR message belongs to the first terminal device, the first terminal device may process according to the second RAR message; if the first terminal device determines that the second RAR message does not belong to the first A terminal device, the first terminal device needs to continue to listen to RAR messages belonging to the first terminal device.
具體地,在情況二中,該方法200可以包括:Specifically, in case two, the
S205、第一終端設備根據第二RAR消息攜帶的前導碼訊息和指示訊息,確定該第二RAR消息不屬於該第一終端設備,該第一終端設備需要繼續監聽屬於自己的RAR消息,其中,該第二RAR消息攜帶的指示訊息與第一請求消息對應的指示訊息不同。S205. The first terminal device determines that the second RAR message does not belong to the first terminal device according to the preamble message and the indication message carried in the second RAR message. The first terminal device needs to continue to listen to its own RAR message, where, The indication message carried in the second RAR message is different from the indication message corresponding to the first request message.
具體地,RAR消息攜帶的指示訊息可以包括以下幾類指示訊息中的至少一類:Specifically, the indication message carried in the RAR message may include at least one of the following types of indication messages:
第一類、the first sort,
第一類指示訊息包括隨機接入請求消息佔用的資源的第二資源訊息。The first type of indication message includes a second resource message of resources occupied by the random access request message.
例如,第一RAR攜帶的指示訊息包括第一請求消息佔用的資源的第二資源訊息,第二RAR攜帶的指示訊息包括第二請求消息佔用的資源的第二資源訊息。For example, the indication message carried by the first RAR includes the second resource message of the resource occupied by the first request message, and the indication message carried by the second RAR includes the second resource message of the resource occupied by the second request message.
作為可選地一例,若採用方式一確定RA-RNTI,第一資源訊息和第二資源訊息的域類別不同。As an optional example, if the first method is used to determine the RA-RNTI, the domain types of the first resource information and the second resource information are different.
例如,第一資源訊息用於指示隨機接入請求消息佔用頻域資源,第二資源訊息用於指示隨機接入請求消息佔用的時域資源。即網路設備和終端設備根據隨機接入請求消息佔用的資源的第一資源訊息確定RA-RNTI,且該第一資源訊息用於指示隨機接入請求消息佔用的頻域資源,該第二資源訊息用於指示隨機接入請求消息佔用的時域資源。For example, the first resource message is used to indicate that the random access request message occupies frequency domain resources, and the second resource message is used to indicate that the random access request message occupies time domain resources. That is, the network device and the terminal device determine the RA-RNTI according to the first resource message of the resource occupied by the random access request message, and the first resource message is used to indicate the frequency domain resource occupied by the random access request message, and the second resource The message is used to indicate the time domain resources occupied by the random access request message.
可選地,該第二資源訊息可以用於指示隨機接入請求消息佔用的時域資源的起始位置和隨機接入請求消息佔用的時域資源的結束位置中的至少一種。Optionally, the second resource message may be used to indicate at least one of a start position of the time domain resource occupied by the random access request message and an end position of the time domain resource occupied by the random access request message.
例如,該第二資源訊息具體用於指示以下訊息中的至少一種:For example, the second resource message is specifically used to indicate at least one of the following messages:
1a、隨機接入請求消息佔用的第一個子幀的編號;1a. The number of the first subframe occupied by the random access request message;
例如,第一RAR消息攜帶的指示訊息包括第二資源訊息,該第二資源訊息用於指示第一請求消息佔用的第一個子幀的編號;第二RAR消息攜帶的第二資源訊息用於指示第二請求消息佔用的第一個子幀的編號。For example, the indication message carried in the first RAR message includes a second resource message, which is used to indicate the number of the first subframe occupied by the first request message; the second resource message carried in the second RAR message is used for Indicates the number of the first subframe occupied by the second request message.
1b、隨機接入請求消息佔用的第一個時隙或第一個迷你時隙的編號;1b. The number of the first time slot or the first mini time slot occupied by the random access request message;
1c、隨機接入請求消息佔用的最後一個子幀的編號;1c. The number of the last subframe occupied by the random access request message;
1d、隨機接入請求消息佔用的最後一個時隙或最後一個迷你時隙的編號。1d. The number of the last time slot or last mini time slot occupied by the random access request message.
1b、1c和1d的說明可以參見1a的相關描述,為了簡潔此處不再贅述。For descriptions of 1b, 1c and 1d, please refer to the relevant descriptions of 1a, and they will not be repeated here for brevity.
通過第一類指示訊息可以將頻域資源和時域資源進行分離。例如,使用隨機接入請求消息佔用的頻域資源確定RA-RNTI,使用隨機接入請求消息佔用的時域資源確定指示訊息,該方法可以使第一終端設備準確地確定屬於自己的RAR消息,同時該方法能夠降低第一終端設備接收RAR消息的複雜度。The first type of indication message can separate frequency domain resources and time domain resources. For example, the frequency domain resource occupied by the random access request message is used to determine the RA-RNTI, and the time domain resource occupied by the random access request message is used to determine the indication message. This method can enable the first terminal device to accurately determine its own RAR message. At the same time, this method can reduce the complexity of the first terminal device receiving the RAR message.
例如,以指示訊息包括1a為例,第一請求消息和第二請求消息佔用的頻域資源均為C,第一前導碼和第二前導碼相同均為D,第一請求消息佔用的第一個子幀的編號為N(N≥0),第二請求消息佔用的第一個子幀的編號為M(M≥0,且M≠N),網路設備接收第二請求消息後發送第二RAR消息,該第二RAR消息包括第二前導碼D的訊息和編號M,由於第一終端設備和第二終端設備使用相同的頻域資源發送隨機接入請求消息,第一終端設備和第二終端設備均可以接收到(監聽到)第二RAR消息。由於編號M與編號N不同,第一終端設備確定該第二RAR消息不屬於自己,第一終端設備繼續監聽屬於自己的RAR消息。若第一終端設備監聽到包括第一前導碼D的訊息和編號M的第一RAR消息,第一終端設備確定該第一RAR消息屬於該第一終端設備。For example, taking the indication message including 1a as an example, the frequency domain resources occupied by the first request message and the second request message are both C, the first preamble and the second preamble are both D, and the first request message occupies the first The number of each subframe is N (N≥0), the number of the first subframe occupied by the second request message is M (M≥0, and M≠N). After receiving the second request message, the network device sends the first Two RAR messages, the second RAR message includes the message of the second preamble D and the number M. Since the first terminal device and the second terminal device use the same frequency domain resource to send the random access request message, the first terminal device and the second Both terminal devices can receive (monitor) the second RAR message. Since the number M is different from the number N, the first terminal device determines that the second RAR message does not belong to itself, and the first terminal device continues to listen to the RAR message that belongs to itself. If the first terminal device listens to the message including the first preamble D and the first RAR message with the number M, the first terminal device determines that the first RAR message belongs to the first terminal device.
作為可選地另一例,若採用方式二確定RA-RNTI,第一資源訊息和第二資源訊息指示的資源的細微性不同,且第一資源訊息指示的資源的細微性大於第二資源訊息指示的資源的細微性。As another optional example, if the second method is used to determine the RA-RNTI, the fineness of the resources indicated by the first resource message and the second resource message are different, and the fineness of the resources indicated by the first resource message is greater than the indication of the second resource message The nuance of resources.
例如,第一資源訊息用於指示隨機接入請求消息(例如,第一請求消息)佔用頻域資源和時域資源,第二資源訊息用於指示隨機接入請求消息(第一請求消息)佔用的時域資源,第一資源訊息指示的時域資源的細微性大於第二資源訊息指示的時域資源的細微性。For example, the first resource message is used to indicate that the random access request message (for example, the first request message) occupies frequency domain resources and time domain resources, and the second resource message is used to indicate that the random access request message (first request message) occupies The time domain resource indicated by the first resource message is more subtle than the time domain resource indicated by the second resource message.
需要說明的是,本發明實施例中的細微性可以是指資源的單位大小。例如,以時域資源為例,無線幀的細微性大於子幀的細微性,子幀的細微性大於時隙的細微性等。其中,該細微性也可以反映時域資源的精確度。換句話說,第二資源訊息指示的時域資源的精確度高於第一資源訊息指示的時域資源的精確度。It should be noted that the subtlety in the embodiments of the present invention may refer to the unit size of resources. For example, taking time-domain resources as an example, the fineness of a radio frame is greater than the fineness of a subframe, and the fineness of a subframe is greater than the fineness of a time slot. Among them, the subtlety can also reflect the accuracy of time domain resources. In other words, the accuracy of the time domain resource indicated by the second resource message is higher than the accuracy of the time domain resource indicated by the first resource message.
例如,第一資源訊息用於指示隨機接入請求消息佔用的無線幀的訊息,第二資源訊息用於指示隨機接入請求消息佔用的子幀的訊息。For example, the first resource message is used to indicate a radio frame message occupied by a random access request message, and the second resource message is used to indicate a subframe message occupied by a random access request message.
又例如,第一資源訊息用於指示隨機接入請求消息佔用的子幀的訊息,第二資源訊息用於指示隨機接入請求消息佔用的時隙(或迷你時隙)的訊息。For another example, the first resource message is used to indicate a subframe message occupied by a random access request message, and the second resource message is used to indicate a time slot (or mini slot) occupied by a random access request message.
通過第二類指示訊息可以平衡接收RAR消息的複雜度以及接收RAR消息的次數。具體地,第一終端設備可以首先根據隨機接入請求消息佔用的頻域資源以及大細微性的時域資源接收一部分RAR消息,可以降低接收RAR消息的複雜度以及RAR消息的接收次數,第一終端設備再根據小細微性的時域資源確定屬於自己的RAR消息(即第一RAR消息),有利於第一終端設備準確地識別屬於自己的RAR消息。The second type of indication message can balance the complexity of receiving RAR messages and the number of times of receiving RAR messages. Specifically, the first terminal device may first receive a part of the RAR message according to the frequency domain resource occupied by the random access request message and the large and detailed time domain resource, which can reduce the complexity of receiving the RAR message and the number of times the RAR message is received. First The terminal device then determines its own RAR message (that is, the first RAR message) according to the small and subtle time domain resources, which is beneficial to the first terminal device to accurately identify the RAR message belonging to itself.
例如,第一終端設備通過三個波束發送第一請求消息E、第二請求消息F和第三請求消息G,第一請求消息E、第二請求消息F和第三請求消息G佔用相同的頻域資源和無線幀,且該三個請求消息佔用的第一個子幀的編號分別是1、2和3,該三個請求消息對應相同的RA-RNTI,第一終端設備可以根據該RA-RNTI接收到該三個請求消息中的任一個(無需嘗試多個RA-RNTI),能夠降低接收RAR消息的複雜度。將用於精確地指示第一請求消息的時域資源的第二資源訊息通過第一RAR消息進行承載,有利於第一終端設備可以準確地識別屬於自己的RAR消息。For example, the first terminal device sends the first request message E, the second request message F, and the third request message G through three beams. The first request message E, the second request message F, and the third request message G occupy the same frequency Domain resources and radio frames, and the numbers of the first subframes occupied by the three request messages are 1, 2, and 3, respectively. The three request messages correspond to the same RA-RNTI, and the first terminal device can use the RA-RNTI The RNTI receives any one of the three request messages (no need to try multiple RA-RNTIs), which can reduce the complexity of receiving RAR messages. Carrying the second resource message for accurately indicating the time domain resource of the first request message through the first RAR message is beneficial to the first terminal device that can accurately identify its own RAR message.
需要說明的是,該第二資源訊息指示的時域資源的細微性越小(精確度越高),終端設備確定自己的RAR消息的準確率越高,能夠高效地提高隨機接入的效率,避免執行無意義的隨機競爭過程。It should be noted that the smaller the nuance of the time domain resource indicated by the second resource message (the higher the accuracy), the higher the accuracy of the terminal device in determining its own RAR message, which can effectively improve the efficiency of random access, Avoid performing meaningless random competition.
例如,仍然使用隨機接入請求消息佔用的頻域資源和起始子幀確定RA-RNTI,第一RAR消息包括的指示訊息為第一請求消息佔用的時隙的編號,該方法能夠提高第一終端設備確定屬於自己RAR消息的準確度,以使第一終端設備可以高效地進行隨機接入過程。For example, the frequency domain resource occupied by the random access request message and the starting subframe are still used to determine the RA-RNTI. The indication message included in the first RAR message is the number of the time slot occupied by the first request message. This method can improve the first The terminal device determines the accuracy of its own RAR message, so that the first terminal device can efficiently perform the random access process.
第二類、The second category,
第二類指示訊息以隨機接入請求消息佔用的第二資源訊息為變數的函數值的訊息。The second type of indication message uses the second resource message occupied by the random access request message as a variable function value message.
例如,第一RAR攜帶的指示訊息包括以第一請求消息佔用的資源的第二資源訊息為變數的函數值的訊息,第二RAR攜帶的指示訊息包括以第二請求消息佔用的資源的第二資源訊息為變數的函數值的訊息。For example, the indication message carried by the first RAR includes a message that takes the second resource message of the resource occupied by the first request message as a variable function value, and the indication message carried by the second RAR includes the second message of the resource occupied by the second request message The resource message is the message of the function value of the variable.
以第二資源訊息用於指示時域資源為例,該指示訊息可以用於指示以下訊息中的至少一種:Taking the second resource message for indicating time domain resources as an example, the indication message may be used to indicate at least one of the following messages:
2a、RAR消息佔用的第一個子幀的編號與隨機接入請求消息佔用的第一個子幀的編號之間的差值;2a. The difference between the number of the first subframe occupied by the RAR message and the number of the first subframe occupied by the random access request message;
例如,第一RAR消息攜帶的指示訊息用於指示第一RAR消息佔用的第一個子幀的編號與第一請求消息佔用的第一個子幀的編號之間的差值,第二RAR消息攜帶的指示訊息用於指示第二RAR消息佔用的第一個子幀的編號與第一請求消息佔用的第一個子幀的編號之間的差值。For example, the indication message carried in the first RAR message is used to indicate the difference between the number of the first subframe occupied by the first RAR message and the number of the first subframe occupied by the first request message, and the second RAR message The indication message carried is used to indicate the difference between the number of the first subframe occupied by the second RAR message and the number of the first subframe occupied by the first request message.
2b、RAR消息佔用的第一個時隙的編號與隨機接入請求消息佔用的第一個時隙的編號之間的差值,或該RAR消息佔用的第一個迷你時隙的編號與隨機接入請求消息佔用的第一個迷你時隙的編號之間的差值;2b. The difference between the number of the first time slot occupied by the RAR message and the number of the first time slot occupied by the random access request message, or the number and randomness of the first mini time slot occupied by the RAR message The difference between the numbers of the first mini slot occupied by the access request message;
2c、RAR消息佔用的最後一個子幀的編號與該隨機接入請求消息佔用的最後一個子幀的編號之間的差值;2c. The difference between the number of the last subframe occupied by the RAR message and the number of the last subframe occupied by the random access request message;
2d、該RAR消息佔用的最後一個時隙的編號與該隨機接入請求消息佔用的最後一個時隙的編號之間的差值,或該RAR消息佔用的最後一個迷你時隙的編號與該隨機接入請求消息佔用的最後一個迷你時隙的編號之間的差值。2d. The difference between the number of the last time slot occupied by the RAR message and the number of the last time slot occupied by the random access request message, or the number of the last mini slot occupied by the RAR message and the random The difference between the numbers of the last mini-slot occupied by the access request message.
2b、2c和2d的說明可以參見2a的相關描述,為了簡潔此處不再贅述。For descriptions of 2b, 2c, and 2d, please refer to the relevant descriptions of 2a, which will not be repeated here for brevity.
第一終端設備接收到RAR消息之後,可以根據RAR消息中的指示訊息確定該RAR消息對應的隨機接入請求消息佔用的時域資源的訊息,並判斷該確定的時域資源的訊息和自己發送的隨機接入請求消息的時域資源的訊息是否相同,若相同,確定該RAR消息屬於自己,若不同,確定該RAR消息不屬於自己並繼續監聽屬於自己的RAR消息。After receiving the RAR message, the first terminal device may determine the information of the time domain resource occupied by the random access request message corresponding to the RAR message according to the indication message in the RAR message, and determine the determined time domain resource message and send it by itself Whether the information of the time domain resource of the random access request message is the same, if it is the same, it is determined that the RAR message belongs to itself, if it is different, it is determined that the RAR message does not belong to itself and continues to listen to the RAR message belonging to itself.
例如,假設指示訊息包括2a,第一請求消息和第二請求消息佔用相同的頻域資源C,第一前導碼和第二前導碼均為D,第一請求消息佔用的第一個子幀的編號為N(N≥0),第二請求消息佔用的第一個子幀的編號為M(M≥0,且M≠N),網路設備接收第二請求消息後在第K(N≤K,且M≠N)個子幀發送第二RAR消息,該第二RAR消息攜帶第二前導碼B的訊息和差值K-M,第一終端設備根據該差值K-M確定第二RAR消息對應的隨機接入請求消息佔用的第一個子幀的編號為M,第一終端設備可以確定該第二RAR消息不屬於該第一終端設備。若第一終端設備監聽到第一RAR消息,該第一RAR消息攜帶第一前導碼D的訊息和差值K-N,第一終端設備根據該差值K-N確定該第二RAR消息對應的隨機接入請求消息佔用的第一個子幀的編號為N,該第一終端設備確定該第一RAR消息對應的隨機接入請求消息與第一請求消息的前導碼訊息和佔用的資源訊息均相同,該第一終端設備確定該第一RAR消息為屬於該第一終端設備。For example, suppose that the indication message includes 2a, the first request message and the second request message occupy the same frequency domain resource C, the first preamble and the second preamble are both D, and the first request frame occupies the first subframe. The number is N (N ≥ 0), the number of the first subframe occupied by the second request message is M (M ≥ 0, and M ≠ N), and the network device receives the second request message in the K (N ≤ K, and M≠N) subframes to send a second RAR message, the second RAR message carries the message of the second preamble B and the difference KM, the first terminal device determines the randomness corresponding to the second RAR message according to the difference KM The number of the first subframe occupied by the access request message is M, and the first terminal device may determine that the second RAR message does not belong to the first terminal device. If the first terminal device listens to the first RAR message, the first RAR message carries the message of the first preamble D and the difference KN, and the first terminal device determines the random access corresponding to the second RAR message according to the difference KN The number of the first subframe occupied by the request message is N. The first terminal device determines that the random access request message corresponding to the first RAR message and the first request message have the same preamble information and occupied resource information. The first terminal device determines that the first RAR message belongs to the first terminal device.
第三類、The third category,
第三類指示訊息包括隨機接入請求消息攜帶的除隨機接入前導碼之外的訊息。The third type of indication message includes messages other than the random access preamble carried in the random access request message.
具體地,該第三類指示訊息可以包括以下訊息中的至少一種:Specifically, the third type of indication message may include at least one of the following messages:
終端設備的位置訊息;Location information of terminal equipment;
例如,第一請求消息攜帶第一終端設備的位置訊息,該第一RAR攜帶第一終端設備的位置訊息;第二請求消息攜帶第二終端設備的位置訊息,該第二RAR攜帶第二終端設備的位置訊息。For example, the first request message carries the location information of the first terminal device, the first RAR carries the location information of the first terminal device; the second request message carries the location information of the second terminal device, and the second RAR carries the second terminal device Location information.
終端設備的標識訊息;Identification information of terminal equipment;
例如,第一請求消息攜帶第一終端設備的標識訊息,該第一RAR攜帶第一終端設備的標識訊息;第二請求消息攜帶第二終端設備的標識訊息,該第二RAR攜帶第二終端設備的標識訊息。For example, the first request message carries the identification message of the first terminal device, the first RAR carries the identification message of the first terminal device; the second request message carries the identification message of the second terminal device, and the second RAR carries the second terminal device Logo message.
終端設備的波束訊息;Beam information of terminal equipment;
隨機接入請求消息的發送時間戳記。例如,第一RAR消息攜帶第一請求消息的發送時間戳記,第二RAR消息攜帶第二請求消息的發送時間戳記。Random access request message transmission timestamp. For example, the first RAR message carries the sending timestamp of the first request message, and the second RAR message carries the sending timestamp of the second request message.
其中,該發送時間戳記可以包括字元序列,用於標識隨機接入請求消息的發送時間,該發送時間戳記還可以具體的發送時刻(例如,北京時間12點15分50秒)。該發送時間戳記還可以是發送時刻的部分訊息(例如,50s)。The sending timestamp may include a sequence of characters, which is used to identify the sending time of the random access request message, and the sending timestamp may also be a specific sending time (for example, 12:15:50 Beijing time). The sending timestamp may also be a partial message at the sending time (for example, 50s).
可選地,若RAR消息攜帶第三類指示訊息,可以將現有LTE系統中的msg2消息和msg3進行融合,能夠節省訊號開銷,提高終端設備隨機接入的效率。Optionally, if the RAR message carries the third type of indication message, the msg2 message and msg3 in the existing LTE system can be merged, which can save signal overhead and improve the efficiency of random access of the terminal device.
例如,第一終端設備發送的第一請求消息攜帶第一前導碼和第一終端設備的標識訊息,若第一終端設備接收到的RAR消息包括該第一前導碼和該標識訊息,該第一終端設備可以確定該RAR消息屬於該第一終端設備,進一步地,該第一終端設備還可以確定該第一終端設備在隨機接入過程中競爭成功。For example, the first request message sent by the first terminal device carries the first preamble and the identification message of the first terminal device. If the RAR message received by the first terminal device includes the first preamble and the identification message, the first The terminal device may determine that the RAR message belongs to the first terminal device. Further, the first terminal device may also determine that the first terminal device successfully competes in the random access process.
以上,描述了RAR消息攜帶的三類指示訊息。具體地,第一終端設備接收到RAR消息之後,判斷RAR消息攜帶的指示訊息和前導碼訊息是否與自己發送的隨機請求消息均匹配,若匹配,第一終端設備確定該RAR消息屬於自己,若不匹配確定該RAR消息不屬於自己。Above, the three types of indication messages carried by the RAR message have been described. Specifically, after receiving the RAR message, the first terminal device determines whether the indication message and the preamble message carried in the RAR message match the random request message sent by itself. If it matches, the first terminal device determines that the RAR message belongs to itself. The mismatch determines that the RAR message does not belong to itself.
例如,若RAR消息攜帶的前導碼訊息指示的隨機接入前導碼與第一請求消息攜帶的第一前導碼相同,該前導碼訊息與第一請求消息匹配。反之,不匹配。For example, if the random access preamble indicated by the preamble message carried in the RAR message is the same as the first preamble carried in the first request message, the preamble message matches the first request message. Otherwise, it does not match.
又例如,若該指示訊息包括資源訊息,且該資源訊息與第一請求消息佔用的資源的第二資源訊息相同(或該指示訊息包括該第一請求消息佔用的資源的第二資源訊息),例如,該指示訊息包括的資源訊息為第一請求消息佔用的第一個子幀的編號,該指示訊息包括的資源訊息與第一請求消息匹配,反之,不匹配。For another example, if the instruction message includes a resource message, and the resource message is the same as the second resource message of the resource occupied by the first request message (or the instruction message includes the second resource message of the resource occupied by the first request message), For example, the resource message included in the indication message is the number of the first subframe occupied by the first request message.
