技术领域technical field

Some enhancements. Specifically, the enhancement will be done by sending the PRACH multiple times. The multiple PRACH transmissions are classified according to the beam direction of the multiple PRACH transmissions, and can be classified into multiple PRACH transmissions of the same beam and multiple PRACH transmissions of different beams.
另一方面，波束失败恢复(Beam Failure Recovery，简称BFR)流程中也有基于RACH流程的过程。而如果BFR流程中采用了前述Msg1重复传输的方式，尤其采用了不同波束的多次Msg1传输方式时，对BFR流程及后续相关流程也会产生影响。而现有技术并没有提供应对这些影响的有效解决方案。On the other hand, there is also a process based on the RACH process in the beam failure recovery (Beam Failure Recovery, BFR for short) process. However, if the aforementioned repeated transmission of Msg1 is used in the BFR process, especially when multiple Msg1 transmissions with different beams are used, it will also have an impact on the BFR process and subsequent related processes. However, the existing technology does not provide an effective solution to deal with these effects.

具体实施方式Detailed ways
如背景技术所言，当BFR流程中采用了Msg1重复传输的方式，尤其采用了不同波束的多次Msg1传输方式时，对BFR流程及后续相关流程也会产生影响。As mentioned in the background art, when the repeated transmission of Msg1 is adopted in the BFR process, especially when multiple Msg1 transmissions of different beams are adopted, it will also have an impact on the BFR process and subsequent related processes.
例如，根据现有协议的相关规定，在用于BFR的控制资源集(control-resource set，简称CORESET)内或者在用于BFR的搜索空间内，终端(也称用户设备，User Equipment，简称UE)成功接收到了小区无线网络临时标识(Cell Radio Network Temporary Identity，简称C-RNTI)或者调制与编码策略无线网络临时标识(Modulation and Coding Scheme Radio Network Temporary Identity，简称MCS-RNTI)加扰循环冗余检验(Cyclic redundancy check，CRC)的物理下行控制信道(Physical Downlink Control Channel，简称PDCCH)之后的28个符号(symbol)之后(如28个正交频分复用(Orthogonal Frequency Division Multiplexing，简称OFDM)符号)，直到UE接收到用于激活物理上行控制信道(Physical Uplink Control Channel，简称PUCCH)空间关系信息(spatialrelationinfo)配置的信令之前，UE发送PUCCH所采用的路损参考信号(Path loss reference signal，简称PLRS)是BFR流程中使用的新波束(new beam)对应的参考信号。其中，UE在专用于波束失败恢复的搜索空间内接收到C-RNTI或者MCS-RNTI加扰CRC的PDCCH则可以标志着波束失败恢复成功。For example, according to the relevant provisions of the existing protocol, in the control resource set (control-resource set, CORESET for short) or in the search space for BFR, the terminal (also called user equipment, User Equipment, UE for short) ) successfully received the Cell Radio Network Temporary Identity (C-RNTI for short) or the Modulation and Coding Scheme Radio Network Temporary Identity (MCS-RNTI for short) scrambling cyclic redundancy Check (Cyclic redundancy check, CRC) after 28 symbols (symbols) after the Physical Downlink Control Channel (PDCCH) (for example, 28 Orthogonal Frequency Division Multiplexing (OFDM) symbol), until the UE receives the signaling for activating the physical uplink control channel (Physical Uplink Control Channel, referred to as PUCCH) spatial relationship information (spatialrelationinfo) configuration, the UE sends the path loss reference signal (Path loss reference signal) used by the PUCCH , PLRS for short) is the reference signal corresponding to the new beam (new beam) used in the BFR process. Wherein, the UE receives the PDCCH scrambled by the C-RNTI or the MCS-RNTI CRC in the search space dedicated for beam failure recovery, which may indicate that the beam failure recovery is successful.
但是，若BFR流程中改为采用Msg1进行不同波束(different beam)重复传输的方式进行时，由于BRF流程中使用了多个波束，则如何选择PUCCH所采用的PLRS就是一个亟需解决的问题。However, if the BFR process is changed to use Msg1 for repeated transmission of different beams (different beams), since multiple beams are used in the BRF process, how to select the PLRS used by the PUCCH is an urgent problem to be solved.
为解决上述技术问题，本发明实施例提供一种物理上行控制信道传输方法，包括：响应于基于随机接入流程的波束失败恢复成功，根据随机接入流程期间传输的消息确定路损参考信号PLRS，其中，所 述随机接入流程包括不同波束的多次物理随机接入信道PRACH传输；使用所述PLRS传输物理上行控制信道PUCCH。In order to solve the above-mentioned technical problems, an embodiment of the present invention provides a physical uplink control channel transmission method, including: in response to the successful recovery of beam failure based on the random access procedure, determining the path loss reference signal PLRS according to the message transmitted during the random access procedure , wherein the random access procedure includes multiple physical random access channel PRACH transmissions of different beams; using the PLRS to transmit a physical uplink control channel PUCCH.
当采用不同波束的多次PRACH传输进行波束失败恢复时，采用本发明方案能够正确进行后续的PUCCH传输，以确保后续通信的正常进行。具体而言，由于本实施场景中波束失败恢复流程期间通过不同的波束进行了多次PRACH传输，因而本实施方案提供了一种改进的PLRS确定方式。根据随机接入流程期间传输的消息而非波束本身来确定PLRS，从而使得采用不同波束的多次PRACH传输进行波束失败恢复这一应用场景中的终端在波束失败恢复成功后能够正确发送PUCCH，以确保和网络的有效通信。When multiple PRACH transmissions of different beams are used to recover from beam failure, the solution of the present invention can correctly perform subsequent PUCCH transmissions to ensure normal progress of subsequent communications. Specifically, since multiple PRACH transmissions are performed through different beams during the beam failure recovery process in this implementation scenario, this implementation solution provides an improved PLRS determination method. The PLRS is determined according to the message transmitted during the random access procedure instead of the beam itself, so that the terminal in the application scenario of beam failure recovery using multiple PRACH transmissions of different beams can correctly send the PUCCH after the beam failure recovery is successful, so that Ensure effective communication with the network.
为使本发明的上述目的、特征和有益效果能够更为明显易懂，下面结合附图对本发明的具体实施例做详细的说明。In order to make the above objects, features and beneficial effects of the present invention more comprehensible, specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.
在一个具体实施中，对于采用发送多次PRACH的方式来增强覆盖的场景，原则上相同波束的多次PRACH传输以及不同波束的多次PRACH传输都适合于进行BFR。其中，对协议改动来说，相同波束的多次PRACH传输对协议的改动较少因而更具可行性。In a specific implementation, for a scenario where coverage is enhanced by sending multiple PRACHs, in principle, multiple PRACH transmissions of the same beam and multiple PRACH transmissions of different beams are suitable for BFR. Wherein, for the protocol modification, multiple PRACH transmissions of the same beam require less protocol modification and thus are more feasible.
相应的，未来可以规定BFR只能采用传统(legacy)方式，即Msg1不做重复传输(repetition)或者只能用采用相同波束的Msg1重复传输的方式进行。具体采用哪一种方式可以通过高层信令配置，或者通过RACH资源来隐式的获知。例如，如果基站没有配置专门用于Msg1重复传输的资源，那么UE就默认只能采用传统的方式，反之则可以认为UE可以采用Msg1重复传输的方式。Correspondingly, in the future, it may be stipulated that BFR can only be performed in a traditional (legacy) manner, that is, Msg1 does not perform repeated transmission (repetition) or can only be performed in the manner of repeated transmission of Msg1 using the same beam. Which method to use can be configured through high-level signaling, or implicitly known through RACH resources. For example, if the base station does not configure resources dedicated to the repeated transmission of Msg1, then the UE can only adopt the traditional method by default; otherwise, it can be considered that the UE can adopt the repeated transmission of Msg1.
而若未来协议确定UE可以采用不同波束的Msg1重复传输来进行BFR，则至少在BFR成功后的PUCCH传输阶段需要进行相应调整，以确保UE能够正确进行PUCCH传输。接下来，对该场景及相应的实现方案进行详细阐述。However, if the future agreement determines that the UE can perform BFR by repeatedly transmitting Msg1 in different beams, at least corresponding adjustments need to be made in the PUCCH transmission stage after the BFR is successful, so as to ensure that the UE can correctly perform PUCCH transmission. Next, the scenario and the corresponding implementation plan are described in detail.
图1是本发明实施例一种物理上行控制信道传输方法的流程图。Fig. 1 is a flowchart of a physical uplink control channel transmission method according to an embodiment of the present invention.
本实施方案可以应用于BFR成功后的PUCCH传输场景，且BFR是采用不同波束的Msg1重复传输进行的。This implementation solution can be applied to the PUCCH transmission scenario after the BFR is successful, and the BFR is performed by using the Msg1 repeated transmission of different beams.
在具体实施中，下述步骤S101～步骤S102所提供的物理上行控制信道传输方法可以由用户设备(也可称为UE)中的具有PUCCH传输功能的芯片执行，也可以由用户设备中的基带芯片执行。In a specific implementation, the physical uplink control channel transmission method provided in the following steps S101 to S102 can be executed by a chip with a PUCCH transmission function in the user equipment (also referred to as UE), or by a baseband in the user equipment. chip implementation.
具体地，参考图1，本实施例所述物理上行控制信道传输方法可以包括如下步骤：Specifically, referring to FIG. 1, the physical uplink control channel transmission method described in this embodiment may include the following steps:
步骤S101，响应于基于随机接入流程的波束失败恢复成功，根据随机接入流程期间传输的消息确定PUCCH资源的路损参考信号PLRS，其中，所述随机接入流程包括不同波束的多次物理随机接入信道PRACH传输；Step S101, in response to the successful recovery of beam failure based on the random access procedure, determine the path loss reference signal PLRS of the PUCCH resource according to the message transmitted during the random access procedure, wherein the random access procedure includes multiple physical Random access channel PRACH transmission;
步骤S102，使用所述PLRS传输PUCCH。Step S102, using the PLRS to transmit the PUCCH.
进一步，步骤S101中所述的不同波束的多次PRACH传输可以用于发送第一消息(即前述消息Msg1)。不同波束上进行的多次PRACH传输可以理解为传输了多次PRACH，不同PRACH占据不同的随机接入时机(Random Access Occasion，简称RO)资源。Further, the multiple PRACH transmissions of different beams described in step S101 may be used to send the first message (ie, the aforementioned message Msg1 ). Multiple PRACH transmissions performed on different beams can be understood as multiple PRACH transmissions, and different PRACHs occupy different Random Access Occasion (Random Access Occasion, RO) resources.
在一个具体实施中，当接收到波束失败恢复成功指示时可以确定BFR成功，自接收到波束失败恢复成功指示起经过预设时段之后，接收到网络更新或者配置PUCCH资源的PLRS之前，此时UE需要确定用于传输PUCCH资源的PLRS。其中，波束失败恢复成功指示可以指的是用户终端在专用于波束失败恢复的搜索空间内接收到C-RNTI或者MCS-RNTI加扰CRC的PDCCH。In a specific implementation, BFR can be determined to be successful when the beam failure recovery success indication is received. After a preset period of time has elapsed since receiving the beam failure recovery success indication, before receiving a network update or a PLRS that configures PUCCH resources, at this time, the UE A PLRS for transmitting PUCCH resources needs to be determined. Wherein, the beam failure recovery success indication may refer to that the user terminal receives a PDCCH scrambled with a CRC by a C-RNTI or an MCS-RNTI in a search space dedicated to beam failure recovery.
例如，在成功接收到了C-RNTI或MCS-RNTI加扰CRC的PDCCH之后的28个符号之后，直到接收到用于激活或者配置PUCCH空间关系信息(spatialrelationinfo)配置的信令之前，UE可以执行步骤S101以自行确定PLRS。其中，成功接收到了C-RNTI或MCS-RNTI加扰的PDCCH即可确定BFR成功，用于激活或者配置PUCCH空间 关系信息配置的信令可以承载有网络配置的PLRS。For example, after successfully receiving 28 symbols after the PDCCH with C-RNTI or MCS-RNTI scrambled CRC, until receiving signaling for activating or configuring PUCCH spatial relationship information (spatialrelationinfo) configuration, the UE may perform the steps S101 to determine the PLRS by itself. Among them, the successful reception of the C-RNTI or MCS-RNTI scrambled PDCCH can determine the success of BFR, and the signaling used to activate or configure PUCCH spatial relationship information configuration can bear the PLRS configured by the network.
在一个具体实施中，步骤S101可以包括步骤：根据所述多次PRACH传输各自占据的RO资源确定优选PRACH；将所述优选PRACH对应的参考信号RS确定为所述PLRS。In a specific implementation, step S101 may include the steps of: determining a preferred PRACH according to RO resources occupied by the multiple PRACH transmissions; and determining a reference signal RS corresponding to the preferred PRACH as the PLRS.
具体地，每次PRACH传输占据的RO资源在时域上可能存在先后，如可以基于RO资源的索引号排序。如果在时域上索引号相同，则不同RO资源在频域上的位置也可能不同。Specifically, the RO resources occupied by each PRACH transmission may have a sequence in the time domain, for example, they may be sorted based on the index numbers of the RO resources. If the index numbers in the time domain are the same, the positions of different RO resources in the frequency domain may also be different.
例如，可以将所述多次PRACH传输各自占据的RO资源中，时域上最靠前或最靠后的RO资源对应的PRACH确定为所述优选PRACH。可以将所有RO资源的索引号进行排序，并将其中排序最前或最后的RO资源对应的PRACH确定为优选PRACH。若时域上最靠前或最靠后的RO资源的数量为多个，则将其中频域上最高或最低的RO资源对应的PRACH确定为所述优选PRACH。For example, among the RO resources occupied by the multiple PRACH transmissions, the PRACH corresponding to the earliest or the last RO resource in the time domain may be determined as the preferred PRACH. The index numbers of all RO resources may be sorted, and the PRACH corresponding to the RO resource sorted first or last is determined as the preferred PRACH. If there are multiple RO resources at the front or at the bottom in the time domain, the PRACH corresponding to the highest or lowest RO resource in the frequency domain is determined as the preferred PRACH.
又例如，可以将所述多次PRACH传输各自占据的RO资源中，选择RO资源索引号最小的RO资源作为优选PRACH，或者选择RO资源索引号最大的RO资源作为优选PRACH。For another example, among the RO resources occupied by the multiple PRACH transmissions, the RO resource with the smallest RO resource index number may be selected as the preferred PRACH, or the RO resource with the largest RO resource index number may be selected as the preferred PRACH.
又例如，可以选择时间上最早传输的PRACH作为优选PRACH，或者选择时间上传输最晚的PRACH作为优选PRACH。For another example, the PRACH transmitted earliest in time may be selected as the preferred PRACH, or the PRACH transmitted latest in time may be selected as the preferred PRACH.
又例如，可以将所述多次PRACH传输各自对应的参考信号中，选择参考信号索引号最小的参考信号作为PUCCH资源的PLRS，或者，选择参考信号索引号最大的参考信号作为PUCCH资源的PLRS。For another example, among the reference signals corresponding to the multiple PRACH transmissions, the reference signal with the smallest reference signal index number may be selected as the PLRS of the PUCCH resource, or the reference signal with the largest reference signal index number may be selected as the PLRS of the PUCCH resource.
又例如，可以从所述多次PRACH传输各自占据的RO资源中随机选取一个RO资源，并将该RO资源对应的PRACH确定为优选PRACH。For another example, one RO resource may be randomly selected from the RO resources occupied by the multiple PRACH transmissions, and the PRACH corresponding to the RO resource is determined as the preferred PRACH.
进一步，网络可以预先配置各PRACH对应的RS，并指示给UE。Further, the network may pre-configure the RS corresponding to each PRACH and indicate it to the UE.
在一个具体实施中，步骤S101可以包括步骤：将所述多次 PRACH传输中信道质量最优的PRACH确定为优选PRACH；将所述优选PRACH对应的RS确定为所述PLRS。In a specific implementation, step S101 may include the steps of: determining the PRACH with the best channel quality in the multiple PRACH transmissions as the preferred PRACH; and determining the RS corresponding to the preferred PRACH as the PLRS.
例如，PRACH的信道质量可以基于其对应的参考信号接收功率(Reference Signal Received Power，简称RSRP)表征。例如，可以在进行随机接入流程期间测量得到PRACH所对应的参考信号的RSRP。For example, the channel quality of the PRACH can be characterized based on its corresponding Reference Signal Received Power (RSRP for short). For example, the RSRP of the reference signal corresponding to the PRACH may be obtained by measuring during the random access procedure.
在一个具体实施中，步骤S101可以包括以下步骤：根据所述多次PRACH传输中各PRACH的索引确定优选PRACH；将所述优选PRACH的RS确定为所述PLRS。In a specific implementation, step S101 may include the following steps: determining a preferred PRACH according to the index of each PRACH in the multiple PRACH transmissions; and determining the RS of the preferred PRACH as the PLRS.
具体地，PRACH的索引可以由网络配置或协议预先设定。Specifically, the PRACH index can be preset by network configuration or protocol.
例如，可以将索引的数值最大或最小的PRACH确定为所述优选PRACH。For example, the PRACH with the largest or smallest index value may be determined as the preferred PRACH.
在一个具体实施中，步骤S101可以包括步骤：在接收所述随机接入流程的第二消息(Msg2)期间，获取指示信息；根据所述指示信息确定所述PLRS。In a specific implementation, step S101 may include the steps of: acquiring indication information during receiving the second message (Msg2) of the random access procedure; and determining the PLRS according to the indication information.
具体地，Msg2(即随机接入响应，Random Access Response，简称RAR)可以是在随机接入流程期间由网络指示给UE的。Specifically, Msg2 (that is, Random Access Response, Random Access Response, RAR for short) may be indicated to the UE by the network during the random access procedure.
进一步，Msg2可以通过物理下行共享信道(Physical Downlink Shared Channel，简称PDSCH)承载。相应的，可以从用于承载所述第二消息的PDSCH中获取所述指示信息。例如，PDSCH可以用于发送RAR的媒体访问控制层控制单元(Media Access Control-Control Element，简称MAC-CE)，则在本示例中可以在MAC-CE中增加X比特来指示PUCCH资源对应的PLRS。其中，X可以是任意正整数。Further, Msg2 may be carried by a Physical Downlink Shared Channel (PDSCH for short). Correspondingly, the indication information may be acquired from the PDSCH used to carry the second message. For example, PDSCH can be used to send the Media Access Control-Control Element of RAR (Media Access Control-Control Element, referred to as MAC-CE), then in this example, X bits can be added to the MAC-CE to indicate the PLRS corresponding to the PUCCH resource . Wherein, X can be any positive integer.
又例如，可以从调度所述PDSCH的物理下行控制信道(Physical Downlink Control Channel，简称PDCCH)中获取所述指示信息。如可以在用于调度RAR的MAC-CE的PDCCH中额外承载一个指示域来指示PUCCH资源对应的PLRS。For another example, the indication information may be obtained from a physical downlink control channel (Physical Downlink Control Channel, PDCCH for short) that schedules the PDSCH. For example, an indication field may be additionally carried in the PDCCH of the MAC-CE for scheduling the RAR to indicate the PLRS corresponding to the PUCCH resource.
进一步，指示信息中可以直接指示PLRS。或者，指示信息可以指示采用不同波束中的哪一个波束传输的PRACH所对应的RS作为PUCCH资源对应的PLRS。Further, the indication information may directly indicate the PLRS. Alternatively, the indication information may indicate which beam among different beams is used to transmit the RS corresponding to the PRACH as the PLRS corresponding to the PUCCH resource.
在一个具体实施中，步骤S101可以包括步骤：将接收波束对应的RS确定为所述PLRS，其中，所述接收波束用于接收所述随机接入流程的第二消息。In a specific implementation, step S101 may include the step of: determining the RS corresponding to the receiving beam as the PLRS, where the receiving beam is used to receive the second message of the random access procedure.
在一个具体实施中，步骤S101可以包括步骤：将发送所述随机接入流程的第三消息(Msg3)所采用的PLRS确定为所述PLRS。In a specific implementation, step S101 may include the step of: determining the PLRS used to send the third message (Msg3) of the random access procedure as the PLRS.
例如，可以将发送Msg3的发送波束对应的RS确定为PLRS。For example, the RS corresponding to the transmission beam for transmitting Msg3 may be determined as the PLRS.
由上，当采用不同波束的多次PRACH传输进行波束失败恢复时，采用本发明方案能够正确进行后续的PUCCH传输，以确保后续通信的正常进行。From the above, when multiple PRACH transmissions of different beams are used to recover from beam failure, the solution of the present invention can correctly perform subsequent PUCCH transmissions to ensure normal progress of subsequent communications.
具体而言，由于本实施场景中波束失败恢复流程期间通过不同的波束进行了多次PRACH传输，因而本实施方案提供了一种改进的PLRS确定方式。根据随机接入流程期间传输的消息而非波束本身来确定PLRS，从而使得采用不同波束的多次PRACH传输进行波束失败恢复这一应用场景中的终端在波束失败恢复成功后能够正确发送PUCCH，以确保和网络的有效通信。Specifically, since multiple PRACH transmissions are performed through different beams during the beam failure recovery process in this implementation scenario, this implementation solution provides an improved PLRS determination method. The PLRS is determined according to the message transmitted during the random access procedure instead of the beam itself, so that the terminal in the application scenario of beam failure recovery using multiple PRACH transmissions of different beams can correctly send the PUCCH after the beam failure recovery is successful, so that Ensure effective communication with the network.
图2是本发明实施例一个典型应用场景的信令交互图。Fig. 2 is a signaling interaction diagram of a typical application scenario according to an embodiment of the present invention.
在本场景中，结合图2，UE21可以执行操作s201，以基于不同波束的多次PRACH传输进行BFR流程。In this scenario, referring to FIG. 2 , UE21 may perform operation s201 to perform a BFR process based on multiple PRACH transmissions of different beams.
接下来，基站22执行操作s202，以向UE21发送采用C-RNTI或MSC-RNTI加扰的PDCCH。相应的，UE21成功接收到采用C-RNTI或MSC-RNTI加扰的PDCCH并确认BFR成功。Next, the base station 22 performs operation s202 to send the PDCCH scrambled with the C-RNTI or the MSC-RNTI to the UE 21 . Correspondingly, UE21 successfully receives the PDCCH scrambled by using C-RNTI or MSC-RNTI and confirms that BFR is successful.
确认BFR成功之后经过28个OFDM符号后，若没有接收到基站22发送的用于激活PUCCH空间关系信息配置的信令，则UE21 执行操作s203，以基于上述图1所示方案自行确定PLRS。After 28 OFDM symbols have passed after confirming that the BFR is successful, if the signaling for activating the PUCCH spatial relationship information configuration sent by the base station 22 is not received, the UE21 performs operation s203 to determine the PLRS by itself based on the scheme shown in FIG. 1 above.
接下来，UE21执行操作s204，以采用确定的PLRS向基站22发送PUCCH。Next, the UE21 performs operation s204 to send the PUCCH to the base station 22 by using the determined PLRS.
在一个变化例中，在执行操作s203和操作s204之前/同时/之后，若接收到基站22通过执行操作s208发送的用于激活PUCCH空间关系信息配置的信令，则UE21可以执行操作s209，采用该信令中配置的PLRS发送PUCCH。此时，UE21将不会再采用基于操作s203确定的PLRS发送PUCCH。In a variation example, before/simultaneously/after performing operation s203 and operation s204, if receiving the signaling for activating PUCCH spatial relationship information configuration sent by base station 22 by performing operation s208, UE21 may perform operation s209, adopt The PLRS configured in the signaling sends the PUCCH. At this time, UE21 will no longer use the PLRS determined based on operation s203 to send the PUCCH.
