For example, A and/or B can mean that there is A alone, A and B exist at the same time, and B exists alone. three situations. In addition, the character "/" in this article generally indicates that the associated objects before and after are in an "or" relationship.
可選地,在NR系統中,基於競爭的隨機存取過程可以採用了四步隨機存取過程,具體地:Optionally, in the NR system, the contention-based random access process may adopt a four-step random access process, specifically:
在第一步驟中,終端設備向網路設備發送隨機存取前導序列(Preamble),即MSG1。In the first step, the terminal device sends a random access preamble, namely MSG1, to the network device.
在第二步驟中,網路設備檢測到有終端設備發送的Preamble之後向終端設備發送隨機存取回應(random access response,RAR)以告知終端設備在發送MSG3時可以使用的上行資源訊息,為終端設備分配臨時無線網路臨時識別字(Radio Network Temporary Identity,RNTI),給終端設備提供定時提前命令(time advance command)等,如果終端設備在RAR時間窗內沒有檢測到RAR,終端設備進行Preamble的重傳,如果終端設備在RAR時間窗內檢測到RAR,並且該RAR中的Preamble索引和該終端設備發送的Preamble索引系統,該終端設備可以確定成功接收到RAR,從而可以停止監聽RAR。進一步地,該終端設備根據RAR指示的上行資源進行MSG3的傳輸。其中,網路設備在發送RAR時使用的RA-RNTI是根據PRACH的時頻資源的位置計算的,一個RA-RNTI擾碼的PDCCH調度的PDSCH中可以包括對於多個Preamble的回應。In the second step, the network device detects the Preamble sent by the terminal device and sends a random access response (RAR) to the terminal device to inform the terminal device of the uplink resource information that can be used when sending MSG3. The device allocates a radio network temporary identity (RNTI) and provides a time advance command (time advance command) to the terminal device. If the terminal device does not detect RAR within the RAR time window, the terminal device performs Preamble For retransmission, if the terminal device detects the RAR within the RAR time window, and the Preamble index in the RAR and the Preamble index system sent by the terminal device, the terminal device can determine that the RAR is successfully received, and can stop monitoring the RAR. Further, the terminal device performs MSG3 transmission according to the uplink resource indicated by the RAR. Wherein, the RA-RNTI used by the network device when sending the RAR is calculated according to the position of the PRACH time-frequency resource, and the PDSCH scheduled by the PDCCH with one RA-RNTI scrambled code may include responses to multiple preambles.
在第三步驟中,終端設備接收到RAR之後,在RAR所指定的上行資源中發送MSG3訊息。In the third step, after receiving the RAR, the terminal device sends the MSG3 message in the uplink resource designated by the RAR.
在第四步驟中,網路設備向終端設備發送MSG4訊息,其中包括競爭解決訊息,同時為終端設備分配上行傳輸資源。終端設備接收到網路設備發送的MSG 4時,會檢測MSG 4中是否包括終端設備發送的MSG3訊息中的部分內容。若包括則表明終端設備隨機存取過程成功,否則認為隨機過程失敗,終端設備需要再次從第一步驟開始發起隨機存取過程。In the fourth step, the network device sends an MSG4 message to the terminal device, which includes a contention resolution message, and at the same time allocates uplink transmission resources for the terminal device. When the terminal device receives the MSG 4 sent by the network device, it will detect whether the MSG 4 includes part of the content in the MSG3 message sent by the terminal device. If it is included, it indicates that the random access process of the terminal device is successful, otherwise it is considered that the random process has failed, and the terminal device needs to initiate the random access process again from the first step.
可選地,在NR系統中,基於競爭的隨機存取過程也可以採用兩步隨機存取過程,具體地:Optionally, in the NR system, the contention-based random access process can also adopt a two-step random access process, specifically:
在第一步驟中,終端設備向網路設備發送Preamble和PUSCH,其中,Preamble和PUSCH分別相當於四步隨機存取過程中的MSG1和MSG3。In the first step, the terminal device sends the Preamble and PUSCH to the network device, where the Preamble and PUSCH are respectively equivalent to MSG1 and MSG3 in the four-step random access process.
其中,該Preamble和PUSCH具有對應關係,具體地,網路設備可以配置Preamble資源和PUSCH資源,以及Preamble資源和PUSCH資源之間的對應關係,可選地,Preamble資源和PUSCH資源可以是一對一,一對多,多對一等的對應關係,以一對多為例,一個Preamble資源可以對應多個PUSCH資源,不同的終端設備可以選擇相同的Preamble資源和不同的PUSCH資源發送該第一步驟中的訊息。Wherein, the Preamble and PUSCH have a corresponding relationship. Specifically, the network device can configure the Preamble resource and the PUSCH resource, and the corresponding relationship between the Preamble resource and the PUSCH resource. Optionally, the Preamble resource and the PUSCH resource can be one-to-one , One-to-many, many-to-one correspondence, take one-to-many as an example, a Preamble resource can correspond to multiple PUSCH resources, and different terminal devices can select the same Preamble resource and different PUSCH resources to send this first step In the message.
在第二步驟中,網路設備檢測到有終端設備發送的存取前導序列之後向終端設備發送隨機存取回應訊息,該隨機存取回應訊息為第一步驟中的Preamble和PUSCH的回應訊息,該隨機存取回應訊息可以包括四步隨機存取中的第二步驟和第四步驟的內容,具體地,該隨機存取回應訊息可以包括RAR和競爭解決訊息。In the second step, the network device detects the access preamble sequence sent by the terminal device and sends a random access response message to the terminal device. The random access response message is the response message of Preamble and PUSCH in the first step. The random access response message may include the content of the second step and the fourth step in the four-step random access. Specifically, the random access response message may include RAR and contention resolution messages.
應理解,上述四步隨機存取過程的延遲較大,通常無法滿足NR系統中低延遲高可靠性場景的需求,而基於兩步隨機存取過程的隨機存取的方法,可以減小隨機存取延遲,有利於滿足對延遲的需求。It should be understood that the aforementioned four-step random access process has a relatively large delay, which usually cannot meet the requirements of low-latency and high-reliability scenarios in the NR system, and the random access method based on the two-step random access process can reduce random memory. Taking delay is conducive to meeting the demand for delay.
