- paging can be divided into:
- Core network paging which comes from the core network.
- the core network In the RRC_IDLE state, when downlink data arrives for the RRC_IDLE state terminal, the core network notifies the terminal through a paging message;
- the base station notifies the terminal through a paging message
- the final paging message is sent by the base station to the terminal through the air interface.
- the paging message is carried by the Paging Control Channel (PCCH), the data block of PCCH is carried by the Paging Channel (PCH), and the data block of PCH is carried by the Physical Downlink Shared Channel (PDSCH). Since PDSCH is a downlink shared physical channel, it can carry not only PCH but also Downlink Shared Channel (DL-SCH). Therefore, before receiving the paging message (on PDSCH), the terminal needs to monitor the Physical Downlink Control Channel (PDCCH) first, and then judge whether the network has sent a paging message to itself in this paging cycle according to whether the PDCCH carries the Paging Radio Network Temporary Identifier (P-RNTI).
- P-RNTI Paging Radio Network Temporary Identifier
- the downlink control information (DCI) that schedules paging can also carry short messages and indicate whether there are available tracking reference signal (TRS) resources.
- DCI downlink control information
- TRS tracking reference signal
- a paging message carries a paging record list (PagingRecordList), which carries at least 1 and at most maxNrofPageRec paging records, and each paging record carries a paging identifier of a paged terminal. That is, a paging message can indicate that at most maxNrofPageRec terminals are paged.
- PagingRecordList paging record list
- each paging record carries a paging identifier of a paged terminal. That is, a paging message can indicate that at most maxNrofPageRec terminals are paged.
- the terminal receiving the paging message is in idle state or inactive state.
- a PF is a radio frame that may contain one or more POs.
- a PO is a subframe that may contain a paging message.
- the terminal uses discontinuous reception (DRX) to receive paging messages.
- DRX discontinuous reception
- the terminal only wakes up once in a DRX cycle to monitor a PO.
- the terminal monitors one PO in each DRX cycle.
- PO is a set of PDCCH monitoring opportunities and can include multiple time slots (such as subframes or symbols) in which paging DCI can be sent.
- the network includes the uplink grant (UL grant) information in the RAR to indicate the scheduling information of the Msg3 Physical Uplink Shared Channel (PUSCH), and includes the Random Access Channel Preamble ID (RAPID), Temporary Cell-Radio Network Temporary Identifier (TC-RNTI), TA and other information. If the network does not receive the Msg3PUSCH, it can schedule the retransmission of the Msg3PUSCH in the PDCCH scrambled by the TC-RNTI.
- UL grant uplink grant
- RAR Random Access Channel Preamble ID
- TC-RNTI Temporary Cell-Radio Network Temporary Identifier
- different terminals randomly select preambles for transmission, so different terminals may select the same preamble to send on the same time-frequency wireless resources (Random Access Channel Occasion (RO) resources), which can be understood as a terminal preamble conflict.
- RO Random Access Channel Occasion
- different terminals will receive the same RAR, and at this time, different terminals will transmit Msg3PUSCH according to the scheduling information in the RAR UL grant.
- the network can only decode the PUSCH (including contention resolution information) sent by one terminal on one Msg3PUSCH scheduling resource, so the network will include the contention resolution information received in Msg3 in Msg4. If the contention resolution information in Msg4 received by the terminal matches the contention resolution information sent by the terminal in Msg3PUSCH, the terminal considers that the contention resolution is successful. If they do not match, the contention resolution is considered unsuccessful.
- the terminal reselects the random access channel (RACH) to send resources, sends the physical random access channel (PRACH), and makes the next random access attempt.
- RACH random access channel
- PRACH physical random access channel
- the two-step random access process 2-step RACH is introduced.
- the first step is that the terminal sends MsgA to the network side. After receiving MsgA, the network side sends MsgB to the terminal. If the terminal does not receive MsgB within a certain period of time, the terminal will accumulate the counter that counts the number of times MsgA is sent and resend MsgA. If the counter that counts the number of times MsgA is sent reaches a certain threshold, the terminal will switch from the 2-step random access process to the 4-step random access process.
- MsgA includes the MsgA preamble part and the MsgA PUSCH part.
- the preamble part is sent on the RO used for 2-step RACH
- the PUSCH part is sent on the MsgA PUSCH resources associated with the sending of the MsgA preamble and the RO.
- MsgA PUSCH resources are a group of PUSCH resources configured relative to each PRACH time slot, including time-frequency resources and demodulation reference signal (DMRS) resources.
- DMRS demodulation reference signal
- PUCCH Physical Uplink Control Channel
- dedicated PUCCH repetition was configured with the PUCCH format, for example, through the nrofSlots parameter in PUCCH-FormatConfig.
- dedicated PUCCH repetition can be configured in each PUCCH resource under PUCCH-config IE, pucch-RepetitionNrofSlots-r17, thereby indirectly achieving dynamic PUCCH repetition.
- the number of repetitions of common PUCCH repeated transmission is ⁇ 1,2,4,8 ⁇ .
- SIB System Information Block
- HARQ is a stop-and-wait protocol that includes multiple processes.
- the so-called stop-and-wait protocol means that the transmitter stops temporarily each time it sends a data packet and waits for confirmation information from the receiver. When the data packet arrives at the receiver, it is error-checked. If it is received correctly, a confirmation signal is returned, and if it is wrong, a non-confirmation signal is returned. When the transmitter receives the confirmation signal, it sends new data, otherwise it resends the last transmitted data packet.
- the so-called multiple processes refer to the transmitter running multiple different stop-and-wait protocols in parallel on the channel, using the gaps between different channels to interleave data and signaling, thereby improving channel utilization.
- uplink HARQ retransmission since in NR, both retransmission and new transmission require DCI indication. If the base station does not receive uplink data at the resource location indicated by the DCI or the received uplink data has errors, the base station will send a new DCI to instruct the terminal to retransmit.
- Autonomous retransmission is introduced in NR for unlicensed band operation. Specifically, if the terminal device does not receive an acknowledgment or dynamic grant for the HARQ process before the timer expires, the terminal device interprets it as a non-acknowledgment for the configured grant transmission. The terminal device then performs retransmission for the HARQ process in the configured grant resources. If there is a new packet to be sent, the retransmission should be given priority.
- Using the configured grant resources for autonomous retransmission as in unlicensed band operation will be detrimental to the deterministic transmission of time-sensitive communication services, because the configured grant resources are used for the retransmission of a previous packet of the time-sensitive communication service, and no resources can be used to send a new packet of the time-sensitive communication service. Therefore, subsequent transmissions of time-sensitive communication services will be delayed.
- Timing Advance Command is a command instructing the terminal to adjust TA.
- the initial time advance command is passed in the RAR message and the time advance command is passed in the Media Access Control-Control Element (MAC-CE) message.
- the initial time advance command is passed in the RAR message: For the first uplink message after PRACH, the terminal applies the timing advance value extracted from the RAR.
- the time advance command is passed in the MAC-CE message: After the initial connection is completed, the terminal adjusts the uplink transmission according to the MAC-CE timing advance.
- the initial TAC through RAR is about 12 bits, and its value range is 0-3846, which is an absolute TA.
- the TAC through MAC-CE is about 6 bits, and its value range is 0-63, which is a relative TA.
- TA is controlled by the MAC layer and implemented by the physical layer. The TA value depends on the signal propagation delay from the base station to the terminal, that is, different terminals located in different locations will have different TA values.
- the goal of TAC is to make the uplink transmission from all terminals to the base station consistent.

下面对本申请实施例提供的一种上行数据传输方法、装置、设备及存储介质中涉及的一些概念和/或术语做一下解释说明。
1、寻呼(paging)
在NR中,按照消息来源,寻呼可以分为:
核心网寻呼,来自于核心网,RRC_IDLE状态下,RRC_IDLE状态终端有下行数据到达时,核心网通过寻呼消息通知终端;
RAN寻呼,来自于基站,RRC_INACTIVE状态终端有下行数据到达时,基站通过寻呼消息通知终端;
最终的寻呼消息下发都是由基站通过空口下发给终端的。
寻呼消息由寻呼控制信道(Paging Control Channel,PCCH)承载,PCCH的数据块又是由寻呼信道(Paging Channel,PCH)来承载,而PCH的数据块又是由物理下行共享信道(Physical Downlink Shared Channel,PDSCH)来承载的。由于PDSCH是下行共享物理信道,所以其上除了可以承载PCH之外,还可以承载下行共享信道(Downlink-Shared Channel,DL-SCH)。因此在接收寻呼消息(PDSCH上)之前,终端需要先去监听物理下行控制信道(Physical Downlink Control Channel,PDCCH),然后根据PDCCH上是否有携带寻呼无线网络临时标识符(Paging-Radio Network Temporary Identifier,P-RNTI),来判断网络在本次寻呼周期是否有发送寻呼消息给自己。
除了发送寻呼消息,调度寻呼的下行控制信息(Downlink Control Information,DCI)还可以携带短消息(short message)和指示是否有可用的跟踪参考信号(Tracking Reference Signal,TRS)资源。
在一条寻呼消息中,携带有一个寻呼记录列表(PagingRecordList),该列表中携带最少1个,最多maxNrofPageRec个寻呼记录,每一个寻呼记录中,携带一个被寻呼终端的寻呼标识。即一条寻呼消息可以指示最多maxNrofPageRec个终端被寻呼。
被寻呼终端有两种标识,一种用于寻呼处于idle态的终端;另外一种用于寻呼inactive态的终端。接收寻呼消息的终端处于idle态或inactive态。
2、寻呼时机(Paging Occasion,PO)和寻呼帧(Paging Frame,PF)
PF是一个无线帧,它可以包含一个或多个PO。PO是可能包含寻呼消息的一个子帧。
终端知道寻呼周期、PF、PO,就可以知道接收寻呼消息的确切时间。为了降低RRC_IDLE或RRC_INACTIVE状态下终端的功耗,终端使用非连续接收(Discontinuous Reception,DRX)方式接收寻呼消息。一个DRX周期内有若干个PF,一个PF对应若干个PO,终端在一个DRX周期内只醒来一次监测一个PO。终端监视每个DRX周期的一个PO。PO是一组PDCCH监视时机,并且可以包括可以发送寻呼DCI的多个时隙(例如子帧或符号)。
3、随机接入过程
在现有技术中,随机接入过程可以是基于竞争的随机接入流程也可以是基于非竞争的随机接入的过程。随机接入过程可以是四步随机接入过程(又叫Type-1随机接入过程)或者两步随机接入过程(又叫Type-2随机接入过程)。
在竞争的4步随机接入过程中,终端首先向网络发送Msg1,包含前导码(preamble);网络检测到preamble后,将发送Msg2或随机接入响应(Random Access Reception,RAR)消息,包含网络所检测到的preamble的编号,以及分配给终端发送Msg3的上行无线资源;终端接收到Msg2后,确认Msg2中携带的preamble的编号中,至少有一个和自己所发送的preamble的编号一致,则根据RAR的指示的资源,发送包含竞争解决信息的Msg3;网络收到Msg3后,将发送包含竞争解决信息的Msg4;终端收到Msg4,确认进行解决信息和自己在Msg3中发送的一致,即完成4步随机接入。
网络在RAR中包含上行授权(UL grant)信息用于指示Msg3物理上行共享信道(Physical Uplink Shared Channel,PUSCH)调度信息,并且包含随机接入信道前导码标识(Random Access Channel Preamble ID,RAPID)、临时小区无线网络临时标识符(Temporary Cell-Radio Network Temporary Identifier,TC-RNTI)、TA等信息。如果网络没有接收到Msg3PUSCH,可以在TC-RNTI加扰的PDCCH中调度Msg3PUSCH的重传。
对于竞争的随机接入过程,不同的终端随机选取preamble进行传输,这样不同的终端可能在相同的时频无线资源(随机接入信道时机(Random Access Channel Occasion,RO)资源)上选取相同的preamble发送,这种情况可以理解为终端的preamble冲突。这种情况下,不同的终端会收到相同的RAR,则此时不同的终端会根据该RAR UL grant中的调度信息,进行Msg3PUSCH的传输。由于现有技术不支持Msg3PUSCH的重复传输,网络在一个Msg3PUSCH调度资源上只能解出一个终端发送的PUSCH(包含竞争解决信息),所以,网络会在Msg4中包含在Msg3中收到的竞争解决信息。如果终端收到的Msg4中的竞争解决信息和终端在Msg3PUSCH中发送的竞争解决信息匹配,则终端认为竞争解决成功。如果不匹配,则认为竞争解决不成功。
如果竞争解决不成功,则终端重新选择随机接入信道(Random Access Channel,RACH)发送资源,进行物理随机接入信道(Physical Random Access Channel,PRACH)发送,进行下一次随机接入尝试。
在NR Rel-16,两步随机接入过程2-step RACH被引入。第一步是终端发送MsgA给网络侧。网络侧接收到MsgA后给终端发送MsgB给终端,如果终端在一定时间内都没有收到MsgB,终端会将统计MsgA发送次数的计数器累加一并重新发送MsgA。如果统计MsgA发送次数的计数器达到一定门限,终端会从2-step随机接入过程切换到4-step随机接入过程。MsgA包括MsgA preamble部分和MsgA PUSCH部分,preamble部分在用于2-step RACH的RO上发送,PUSCH部分在跟发送MsgA preamble以及RO想关联的MsgA PUSCH资源上发送。MsgA PUSCH资源是相对于每个PRACH时隙配置的一组PUSCH资源,包括时频资源和解调参考信号(Demodulation Reference Signal,DMRS)资源。
4、重复传输
通常来说,由于终端功率受限等因素的影响,上行信道的覆盖更容易受限,需要考虑通过重复传输来提高覆盖或者可靠性。以物理上行控制信道(Physical Uplink Control Channel,PUCCH)重复传输为例,分为专用(dedicated)PUCCH重复传输和公共(common)PUCCH重复传输。
在NR Rel-16之前,专用PUCCH重复传输是跟PUCCH format绑定配置的,比如通过PUCCH-FormatConfig中nrofSlots参数配置。在NR Rel-17,专用PUCCH重复传输可以PUCCH-config IE下面的每个PUCCH资源中pucch-RepetitionNrofSlots-r17来配置,从而间接实现动态PUCCH重复传输。
公共PUCCH重复传输的重复次数为{1,2,4,8}。支持的配置PUCCH重复传输的指示方式,主要有两种:一是通过系统信息块(System Information Block,SIB)配置一个重复次数,则具备公共PUCCH重复传输的传输能力的终端可以基于配置的重复次数进行传输;二是通过SIB配置至少两个重复次数,则具备公共PUCCH重复传输的传输能力的终端能够被基站动态调度进行PUCCH重复传输,指示的重复次数为至少两个重复次数中某一个。
5、混合自动重传请求(Hybrid Automatic Repeat reQuest,HARQ)重传
HARQ方案既增加了系统的可靠性又提高了系统的传输效率。HARQ是一种包含多个进程的停等式协议。所谓停等式协议,就是发送端每发送一个数据分组包就暂时停下来,等待接收端的确认信息。当数据包到达接收端时,对其进行检错,若接收正确,返回确认信号,错误则返回不确认信号。当发端收到确认信号,就发送新的数据,否则重新发送上次传输的数据包。所谓多个进程指的是发送端在信道上并行地运行多套不同的停等式协议,利用不同信道间的间隙来交错地传递数据和信令,从而提高了信道利用率。对于上行HARQ重传,由于NR中,无论重传和新传都需要DCI指示。如果基站在DCI指示的资源位置没有接收到上行数据或者接收到的上行数据存在错误,那么基站就会发送新的DCI指示终端进行重传。
NR中针对未许可频带操作引入自主重传,具体地,如果终端设备在定时器到期之前没有接收到针对HARQ过程的确认或动态授权,则终端设备解译为针对配置授权传输的非确认。然后,终端设备在配置授权资源中执行针对HARQ过程的重传。如果存在要发送的新分组,则应当优先处理重传。如在未许可频带操作中那样使用配置授权资源进行自主重传将不利于时间敏感通信业务的确定性传输,因为配置授权资源被用于时间敏感通信业务的一个先前分组的重传,而没有资源可被用于发送时间敏感通信业务的新分组。因此,时间敏感通信业务的后续传输将被延迟。
6、TA
TA是基站发给终端的,指示在发送上行信道(例如PUSCH、PUCCH)及探测参考信号(Sounding Reference Signal,SRS)时调整的时间提前量;时间提前量命令(Timing Advance Command,TAC)是指示终端的调整TA的命令。
在NR中,TA信息传递给终端主要有两种方式:RAR消息中传递初始时间提前命令和媒体接入控制控制单元(Media Access Control-Control Element,MAC-CE)消息中传递的时间提前命令。其中,RAR消息中传递初始时间提前命令:对于PRACH之后的第一个上行链路消息,终端应用从RAR中提取的定时提前值。MAC-CE消息中传递的时间提前命令:初始连接完成后,终端根据MAC-CE定时提前调整上行传输。
通过RAR的初始TAC约为12位,其值范围为0–3846,是一个绝对TA。通过MAC-CE的TAC约为6位,其值范围为0-63,是一个相对TA。TA由MAC层控制,物理层实现。TA值取决于从基站到终端的信号传播时延,即位于不同位置的不同终端将具有不同的TA值。TAC的目标是使从所有终端到基站的上行链路传输一致。
