技术领域Technical field

本申请涉及通信领域，并且更具体地，涉及一种用于传输数据的方法和终端设备。The present application relates to the field of communications and, more particularly, to a method and terminal device for transmitting data.

背景技术Background technique

移动通信***的传统工作频段主要集中在6GHz以下的频段，使得频谱资源十分拥挤。为了实现极高速短距离通信，以及支持5G容量和传输速率等方面的需求，移动通信***采用高频频段(比如大于或等于6GHz以上的频段)传输信号以缓解频谱资源紧张的现状。为了克服高频频段与生俱来的高路损的缺陷，物理层需要采用高增益的波束天线来提高链路覆盖。高频小区可以采用波束对(beam pair)进行数据传输，具体即：发送端对准一个方向或波束(beam)进行数据发送，接收端也需要对准相应的方向或波束接收数据。比如，终端设备与网络设备可以通过至少一个波束对进行数据传输。The traditional operating frequency bands of mobile communication systems are mainly concentrated in the frequency bands below 6 GHz, making the spectrum resources very crowded. In order to achieve extremely high-speed short-distance communication, and support for 5G capacity and transmission rate requirements, mobile communication systems use high-frequency bands (such as bands greater than or equal to 6GHz) to transmit signals to alleviate the current situation of spectrum resources. In order to overcome the inherent high path loss of high frequency bands, the physical layer needs to use high gain beam antennas to improve link coverage. The high-frequency cell can transmit data by using a beam pair. Specifically, the transmitting end is aligned with one direction or beam for data transmission, and the receiving end also needs to be aligned with the corresponding direction or beam to receive data. For example, the terminal device and the network device can perform data transmission through at least one beam pair.

若终端设备移动或位置发生改变，则波束的信号(接收或发送)强度会出现变化(增强或减弱)，影响数据传输。并且，目前尚无有效地解决方案。因此，亟需提出一种方法针对高频频段中的波束进行管理。If the terminal device moves or the position changes, the signal (receive or transmit) strength of the beam changes (increases or decreases), affecting data transmission. And, there is currently no effective solution. Therefore, there is a need to propose a method for managing beams in a high frequency band.

S210，终端设备接收网络设备发送的第一控制信息，所述第一控制信息包括至少一个上行波束的标识信息，所述第一控制信息用于指示所述至少一个上行波束是否有效；S210: The terminal device receives the first control information that is sent by the network device, where the first control information includes the identifier information of the at least one uplink beam, where the first control information is used to indicate whether the at least one uplink beam is valid.

可选地，所述第一控制信息可以包括所述至少一个上行波束的标识信息(比如，beam ID或索引index信息)，使得所述终端设备可以根据波束的标识信息识别出对应的波束。Optionally, the first control information may include identification information (for example, beam ID or index index information) of the at least one uplink beam, so that the terminal device may identify the corresponding beam according to the identifier information of the beam.

可选地，所述至少一个上行波束可以是上行服务波束。其中，服务波束可以指用于终端设备与网络设备之间进行数据传输的波束。服务波束可以包括上行服务波束和下行服务波束。Optionally, the at least one uplink beam may be an uplink serving beam. The service beam may refer to a beam used for data transmission between the terminal device and the network device. The service beam may include an uplink service beam and a downlink service beam.

可选地，在本申请实施例中，波束“有效”可以指：接收端(具体可以是网络设备)在检测到某一波束的信号质量大于某一阈值时，可以认为该波束是有效的；反之，可以认为该波束是无效或失效的。或者，波束“有效”也可以理解为波束是可用的，对应地，波束“无效”或“失效”理解为波束是不可用的。Optionally, in the embodiment of the present application, the beam “valid” may be: the receiving end (specifically, the network device) may consider that the beam is valid when detecting that the signal quality of a certain beam is greater than a certain threshold; Conversely, the beam can be considered invalid or invalid. Alternatively, a beam "valid" can also be understood as a beam is available, and correspondingly, a beam "invalid" or "failed" is understood to be that the beam is not available.

在本申请实施例中，“无效”可以理解为“失效”，“失效”也可以理解为“无效”。本申请实施例引入术语“无效”和“失效”只是为了便于从不同的角度定义波束的状态，并不对本申请实施例构成限定。比如，从网络设备侧来讲，网络设备可以向终端设备指示波束有效或无效；从终端设备侧来讲，终端设备可以通过测量，确定波束有效或波束失效。当然，这里只是示例性地说明，具体用哪个术语描述可以结合具体实施例。本领域人员能够理解，波束“失效”或“无效”术语的使用并不对本申请实施例构成限定。In the embodiment of the present application, “invalid” can be understood as “invalid”, and “invalid” can also be understood as “invalid”. The terms "invalid" and "failed" are introduced in the embodiment of the present application only to facilitate the definition of the state of the beam from different angles, and are not limited to the embodiments of the present application. For example, from the network device side, the network device can indicate to the terminal device that the beam is valid or invalid; from the terminal device side, the terminal device can determine whether the beam is valid or beam failure by measurement. Of course, the description herein is merely illustrative, and specific terminology may be used in conjunction with the specific embodiments. Those skilled in the art will appreciate that the use of the term "failed" or "invalid" of a beam does not limit the embodiments of the present application.

这里，上行波束可以包含beam pair中终端设备的传输波束。Here, the uplink beam may include a transmission beam of the terminal device in the beam pair.

对应地，网络设备可以向终端设备发送所述第一控制信息，以告诉终端设备哪些波束有效或哪些波束无效。Correspondingly, the network device may send the first control information to the terminal device to tell the terminal device which beams are valid or which beams are invalid.

比如，网络设备可以基于对beam pair的测量，实现对beam pair的管理。具体比如：若某些上行波束是有效的，则网络设备可以增加有效的上行波束；若某些上行波束是无效的，则网络设备可以对无效的上行波束进行删除操作。并且，网络设备将有效上行波束或无效上行波束通过第一控制信息告知给终端设备。另外，若某些上行波束是有效的，网络设备还可以告知终端设备可以继续使用这些波束，以便进行数据传输过程。For example, the network device can manage the beam pair based on the measurement of the beam pair. For example, if some uplink beams are valid, the network device can add a valid uplink beam; if some uplink beams are invalid, the network device can delete the invalid uplink beam. Moreover, the network device notifies the terminal device of the valid uplink beam or the invalid uplink beam by using the first control information. In addition, if some uplink beams are valid, the network device can also inform the terminal device that the beams can continue to be used for the data transmission process.

可选地，所述第一控制信息可以通过媒体接入控制层控制元素(Medium Access Control，MAC)层消息或物理(Physical，PHY)层信令发送。比如，第一控制信息可以通过随机接入响应消息(Random Access Response，RAR)或媒体接入控制层控制元素(Medium Access Control Control Elements，MAC CE)发送；又比如，第一控制信息还可以通过下行控制信令(Downlink Control Information，DCI)发送。Optionally, the first control information may be sent by a medium access control layer (Medium Access Control, MAC) layer message or physical (PHY) layer signaling. For example, the first control information may be sent by a random access response message (RAR) or a medium access control control element (MAC CE); for example, the first control information may also pass Downlink Control Information (DCI) is sent.

可选地，若所述第一控制信息是通过物理层信令发送的，则所述终端设备的物理层需要把所述第一控制信息通知给所述终端设备的MAC层。也就是说，终端设备的物理层可以接收网络设备发送的所述第一控制信息。Optionally, if the first control information is sent by physical layer signaling, the physical layer of the terminal device needs to notify the first control information to the MAC layer of the terminal device. That is, the physical layer of the terminal device can receive the first control information sent by the network device.

S220，若所述第一控制信息指示所述至少一个上行波束有效，所述终端设备确定所述至少一个上行波束在预设时长内有效；S220. If the first control information indicates that the at least one uplink beam is valid, the terminal device determines that the at least one uplink beam is valid within a preset duration.

具体地，第一控制信息可以指示所述至少一个上行波束是否有效。如果所述第一控制信息指示所述至少一个上行波束是有效的，则终端设备可以确定所述至少一个上行波束在预设时长内有效。终端设备可以使用这些有效的上行波束与网络设备进行数据通信，比如，终端设备可以这些使用有效的上行波束，传输以下数据中的至少一种：调度请求 (Scheduling request，SR)、信道状态信息(Channel status information，CSI)、混合自动重传请求(Hybrid Automatic Repeat reQuest，HARQ)反馈feedback、信道探测参考信号(Sounding Reference Signal，SRS)、半静态调度(Semi-Persistent Scheduling，SPS)、免授权Grant free、用户面数据、控制面数据等。Specifically, the first control information may indicate whether the at least one uplink beam is valid. And if the first control information indicates that the at least one uplink beam is valid, the terminal device may determine that the at least one uplink beam is valid for a preset duration. The terminal device can use these effective uplink beams to perform data communication with the network device. For example, the terminal device can transmit at least one of the following data by using a valid uplink beam: a scheduling request (SR), channel state information ( Channel status information (CSI), Hybrid Automatic Repeat reQuest (HARQ) feedback feedback, Sounding Reference Signal (SRS), Semi-Persistent Scheduling (SPS), Unlicensed Grant Free, user plane data, control plane data, etc.

其中，SR用于终端设备告知网络设备：该终端设备有上行数据待发送。可选地，SR可以通过物理上行控制信道(Physical Uplink Control Channel，PUCCH)进行传输。The SR is used by the terminal device to notify the network device that the terminal device has uplink data to be sent. Optionally, the SR may be transmitted through a Physical Uplink Control Channel (PUCCH).

CSI可以包括：信道质量指示(Channel Quality Indicator，CQI)、预编码矩阵指示(Precoding Matrix Indicator，PMI)、预编码类型指示(Precoding Type Indicator，PTI)、分集指示(Rank Indication，RI)。CSI主要用于终端设备告诉网络设备下行信道的质量，使得网络设备基于下行信道质量进行下行调度。其中，CQI用于选择调制编码方案。PMI用于选择多天线多入多出(Multiple-Input Multiple-Output，MIMO)的码本。PTI用于指示预编码类型。RI用于指示多天线MIMO中天线矩阵的秩。可选地，CSI也可以通过PUCCH进行传输。The CSI may include: a Channel Quality Indicator (CQI), a Precoding Matrix Indicator (PMI), a Precoding Type Indicator (PTI), and a Rank Indication (RI). The CSI is mainly used by the terminal device to tell the network device the quality of the downlink channel, so that the network device performs downlink scheduling based on the downlink channel quality. Among them, CQI is used to select a modulation and coding scheme. PMI is used to select a multiple-input multiple-output (MIMO) codebook. PTI is used to indicate the precoding type. The RI is used to indicate the rank of the antenna matrix in multi-antenna MIMO. Alternatively, the CSI can also be transmitted through the PUCCH.

HARQ feedback用于下行的数据的反馈。SRS用于网络设备进行上行信道质量测量或波束管理。HARQ feedback is used for feedback of downlink data. The SRS is used by the network device for uplink channel quality measurement or beam management.

SPS适用于IP网络传送语音(Voice over Internet Protocol，VoIP)业务等周期性发包，包大小基本固定的业务场景。半静态调度时，网络设备与终端设备按照双方的约定周期性地预留、使用特定的无线承载(Radio Bearer，RB)资源，减少了PDCCH的开销。The SPS is applicable to a service scenario in which the packet size is basically fixed, such as a voice over Internet Protocol (VoIP) service. During semi-persistent scheduling, the network device and the terminal device periodically reserve and use specific Radio Bearer (RB) resources according to the agreement of both parties, which reduces the PDCCH overhead.

Grant free是指：终端设备使用Grant free发送数据前，不需要网络设备动态的分配专用的资源。还可以理解为，终端设备使用的Grant free资源是基于竞争的，至少一个终端设备可以共享该资源。引入Grant free主要为了节省终端设备的电能。Grant free means that the terminal device does not need to dynamically allocate dedicated resources to the network device before sending data using Grant free. It can also be understood that the Grant free resource used by the terminal device is contention-based, and at least one terminal device can share the resource. Grant free is mainly introduced to save power of terminal equipment.

应理解，这里只是示例性地描述了终端设备在上行传输时可能的一些传输信息，实际中可以包括其他合理的传输信息，并不对本申请实施例构成限定。It should be understood that some of the transmission information that may be used by the terminal device in the uplink transmission is exemplarily described herein, and other reasonable transmission information may be included in the actual configuration, which is not limited to the embodiment of the present application.

或者，如果所述第一控制信息指示所述至少一个上行波束是无效的，则终端设备不在所述至少一个上行波束上进行上行传输。具体即，终端设备不使用所述至少一个上行波束传输上述数据。Alternatively, if the first control information indicates that the at least one uplink beam is invalid, the terminal device does not perform uplink transmission on the at least one uplink beam. Specifically, the terminal device does not use the at least one uplink beam to transmit the foregoing data.

具体而言，终端设备在接收到网络设备发送的第一控制信息时，可以引入第一定时器。该第一定时器可以具体为终端设备的MAC层的定时器。比如，第一定时器可以为beam pair Timer。或者，所述第一定时器可以理解为：终端设备使用所述第一定时器维护其上行波束的有效时间。Specifically, the terminal device may introduce the first timer when receiving the first control information sent by the network device. The first timer may be specifically a timer of a MAC layer of the terminal device. For example, the first timer can be a beam pair timer. Alternatively, the first timer may be understood as: the terminal device uses the first timer to maintain the effective time of its uplink beam.

For example, the network device notifies the terminal device of the duration of the first timer by using physical layer signaling, a radio resource control (RRC) message, or a MAC CE.

这里，若所述第一控制信息指示所述至少一个上行波束有效，终端设备可以启动或重启第一定时器。在第一定时器运行期间，终端设备可以确定所述至少一个上行波束是有效的。那么，终端设备可以允许在所述至少一个上行波束上进行数据传输。比如，终端设备可以使用beam pair对应的终端设备的专用上行资源和相关配置，具体包括时域资源、频域资源、码域资源或空域资源等。具体地，“重启第一定时器”是指：若终端设备在第一定时器运行期间接收到所述第一控制信息，且所述第一控制信息指示所述至少一个上行波束是有效的，则终端设备可以重启所述第一定时器。Here, if the first control information indicates that the at least one uplink beam is valid, the terminal device may start or restart the first timer. During operation of the first timer, the terminal device may determine that the at least one uplink beam is active. Then, the terminal device can allow data transmission on the at least one uplink beam. For example, the terminal device may use a dedicated uplink resource and related configuration of the terminal device corresponding to the beam pair, and specifically includes a time domain resource, a frequency domain resource, a code domain resource, or an airspace resource. Specifically, the “restarting the first timer” means: if the terminal device receives the first control information during the running of the first timer, and the first control information indicates that the at least one uplink beam is valid, Then the terminal device can restart the first timer.

可选地，作为一个实施例，所述方法还可以包括：Optionally, as an embodiment, the method may further include:

具体而言，在所述第一定时器运行期间，如果所述第一控制信息指示所述至少一个上行波束无效的，那么终端设备可以确定所述至少一个上行波束是无效的，并且停止所述第一定时器。Specifically, during the running of the first timer, if the first control information indicates that the at least one uplink beam is invalid, the terminal device may determine that the at least one uplink beam is invalid, and stop the The first timer.

可选地，所述终端设备不使用所述至少一个上行波束对应的传输资源传输数据。换言之，所述至少一个上行波束对在所述第一定时器超时或停止后是无效的。Optionally, the terminal device does not use the transmission resource corresponding to the at least one uplink beam to transmit data. In other words, the at least one uplink beam pair is invalid after the first timer expires or stops.

Optionally, the terminal device may release the SR, CSI, HARQ feedback, SRS, SPS, and Grant free resources configured on the at least one uplink beam.

可选地，若以终端设备的物理PHY层和MAC层的角度描述，所述方法可以包括：所述终端设备的PHY层可以根据所述第一控制信息确定所述至少一个上行波束是否有效。如果所述终端设备的PHY层确定所述至少一个上行波束无效，那么终端设备的PHY层可以告知终端设备的MAC层所述至少一个上行波束无效。终端设备的MAC层在收到终端设备的PHY层的通知后，不允许通过所述至少一个上行波束发送以下至少一种数据：SR、CSI、HARQ feedback、SRS、SPS或Grant free等。这里，终端设备的PHY层可以发送随机接入前导序列，以进行随机接入过程，从而获取有效的上行波束。Optionally, if the description is performed by using a physical PHY layer and a MAC layer of the terminal device, the method may include: determining, by the PHY layer of the terminal device, whether the at least one uplink beam is valid according to the first control information. If the PHY layer of the terminal device determines that the at least one uplink beam is invalid, the PHY layer of the terminal device may inform the MAC layer of the terminal device that the at least one uplink beam is invalid. After receiving the notification of the PHY layer of the terminal device, the MAC layer of the terminal device does not allow to transmit at least one of the following data through the at least one uplink beam: SR, CSI, HARQ feedback, SRS, SPS, or Grant free. Here, the PHY layer of the terminal device may send a random access preamble sequence to perform a random access procedure, thereby acquiring a valid uplink beam.

可选地，如果终端设备的服务小区中的所有服务波束都失效，或者，该服务小区中所有服务波束对应的定时器都超时，那么终端设备可以清空该服务小区中的所有HARQ 缓存(buffer)中缓存的数据。这样，能够避免终端设备进行不符合网络设备期望的非自适应重传，从而避免了对其他终端设备数据传输的干扰。Optionally, if all service beams in the serving cell of the terminal device are invalid, or the timers corresponding to all service beams in the serving cell are timed out, the terminal device may clear all HARQ buffers in the serving cell. The data cached in . In this way, it is possible to prevent the terminal device from performing non-adaptive retransmission that does not meet the network device expectation, thereby avoiding interference with data transmission of other terminal devices.

在第一定时器超时或停止后，也可以理解为至少一个上行波束失效后，或者，在终端设备收到的第一控制信息指示至少一个上行波束无效的情况下，终端设备可以进行后续波束训练(beam training)操作，以获取有效的上行波束。可选地，所述波束训练操作可以包括随机接入过程。也就是说，终端设备可以通过随机接入过程，获取至少一个有效的上行波束，或至少一对有效的beam pair。After the first timer expires or stops, it can also be understood that after at least one uplink beam fails, or when the first control information received by the terminal device indicates that at least one uplink beam is invalid, the terminal device can perform subsequent beam training.

可选地，作为一个实施例，所述方法200可以包括：Optionally, as an embodiment, the method 200 may include:

所述终端设备的PHY层接收所述网络设备发送的下行波束的标识信息；The PHY layer of the terminal device receives the identifier information of the downlink beam sent by the network device;

所述终端设备的PHY层将所述下行波束的标识信息发送给所述终端设备的MAC层；The PHY layer of the terminal device sends the identifier information of the downlink beam to the MAC layer of the terminal device;

无线接口可以分为三个协议层，从下到上依次是：物理层(L1)、数据链路层(L2)和网络层(L3)。L1主要用于为高层业务提供传输的无线物理通道。L2从下至上依次是：分组数据汇聚(Packet Data Convergence Protocol，PDCP)、无线链路层控制(Radio Link Control，RLC)、媒体接入控制(Medium Access Control，MAC)、物理(Physical)层。L3包括接入层中的RRC子层和非接入层的移动性管理(Mobility Management，MM)和呼叫控制(Call Control，CC)。其中，PHY层为设备之间的数据通信提供传输媒体及互连设备，为数据传输提高可靠环境，MAC层可以以规定的格式向PHY层发送数据。The wireless interface can be divided into three protocol layers, from bottom to top: physical layer (L1), data link layer (L2), and network layer (L3). L1 is mainly used to provide wireless physical channels for transmission of high-level services. From the bottom to the top, L2 is: Packet Data Convergence Protocol (PDCP), Radio Link Control (RLC), Medium Access Control (MAC), and Physical (Physical) layer. L3 includes Mobility Management (MM) and Call Control (CC) of the RRC sublayer and the non-access stratum in the access layer. The PHY layer provides a transmission medium and an interconnection device for data communication between devices, and improves a reliable environment for data transmission, and the MAC layer can send data to the PHY layer in a prescribed format.

具体而言，终端设备的PHY层可以接收网络设备发送的某一个下行波束的标识信息(DL beam ID或index)。其中，一个随机接入信道(Random Access Channel，RACH)资源池可以关联或对应一个DL beam ID或index。然后，终端设备的PHY层把下行波束的标识信息发送给终端设备的MAC层。终端设备的MAC层可以在下行波束的标识信息对应的RACH资源池中，选择一个RACH资源(比如第一随机接入信道资源)。接着，所述终端设备的MAC层将所述第一随机接入信道资源发送给所述终端设备的PHY层。所述终端设备的PHY层使用所述第一随机接入信道资源，在至少一个发送波束中向网络设备发送随机接入前导序列。比如，终端设备的PHY层通过该RACH资源向网络设备发送前导序列。对应地，所述网络设备通过至少一个接收波束接收所述随机接入前导序列，并根据所述至少一个接收波束中接收到的所述随机接入前导序列的信号质量，确定所述至少一个发送波束中的哪些发送波束是有效的，哪些发送波束是无效的。可选地，所述网络设备可以通过第一控制信息告知所述终端设备哪些发送波束是有效的，哪些发送波束是无效的。Specifically, the PHY layer of the terminal device may receive identification information (DL beam ID or index) of a certain downlink beam sent by the network device. A random access channel (RACH) resource pool can be associated with or corresponding to a DL beam ID or index. Then, the PHY layer of the terminal device transmits the identification information of the downlink beam to the MAC layer of the terminal device. The MAC layer of the terminal device may select one RACH resource (such as the first random access channel resource) in the RACH resource pool corresponding to the identifier information of the downlink beam. Then, the MAC layer of the terminal device sends the first random access channel resource to the PHY layer of the terminal device. The PHY layer of the terminal device uses the first random access channel resource to send a random access preamble sequence to the network device in at least one transmit beam. For example, the PHY layer of the terminal device sends a preamble sequence to the network device through the RACH resource. Correspondingly, the network device receives the random access preamble sequence by using at least one receiving beam, and determines the at least one sending according to a signal quality of the random access preamble sequence received in the at least one receiving beam. Which transmit beams in the beam are valid and which transmit beams are invalid. Optionally, the network device may notify, by using the first control information, which of the transmit beams are valid and which transmit beams are invalid.

也就是说，终端设备的MAC层可以通过与终端设备的PHY层进行交互，获知beam ID或index，并根据beam ID或index选择RACH资源，最后将选择的RACH资源通知给终端设备的PHY层，以便于进行随机接入过程，以进行波束训练操作，从而获取有效的波束。That is, the MAC layer of the terminal device can learn the beam ID or index by interacting with the PHY layer of the terminal device, and select the RACH resource according to the beam ID or index, and finally notify the selected device RACH resource to the PHY layer of the terminal device. A random access procedure is performed to perform a beam training operation to obtain an effective beam.

可选地，终端设备的MAC层将所述第一随机接入信道资源发送给所述终端设备的PHY层时，还可以将初始发送功率告知给终端设备的PHY层。终端设备的PHY层可以使用该初始发送功率在RACH资源上进行随机接入。Optionally, when the MAC layer of the terminal device sends the first random access channel resource to the PHY layer of the terminal device, the initial transmit power may also be notified to the PHY layer of the terminal device. The PHY layer of the terminal device can perform random access on the RACH resource using the initial transmit power.

可选地，所述初始发送功率可以携带于网络设备发送的随机接入配置信息中。比如，所述随机接入配置信息可以包括功率控制信息和/或随机接入资源信息，该功率控制信息可以包括所述初始发送功率和功率攀升的步长。Optionally, the initial transmit power may be carried in random access configuration information sent by the network device. For example, the random access configuration information may include power control information and/or random access resource information, and the power control information may include a step size of the initial transmit power and power climb.

可选地，终端设备的MAC层也有可能没有接收到终端设备的PHY层发送的所述第一指示。即终端设备的MAC层未与终端设备的PHY层交互，也未获得beam ID或index。在这种情况下，终端设备的MAC层可以在前一次发送前导序列的RACH资源池(也可以指上一次随机接入成功时的RACH资源池)中选择一个RACH资源。同时，终端设备的MAC层可以在前一次发送前导序列的发送功率的基础上，按照所述功率攀升的步长，增加一个步长的功率作为发送功率。类似地，终端设备的MAC层把该发送功率和选择的RACH资源发送给终端设备的PHY层，使得终端设备的PHY层可以使用该发送功率在选择的RACH资源上进行随机接入。Optionally, the MAC layer of the terminal device may also not receive the first indication sent by the PHY layer of the terminal device. That is, the MAC layer of the terminal device does not interact with the PHY layer of the terminal device, nor does it obtain the beam ID or index. In this case, the MAC layer of the terminal device may select one RACH resource in the RACH resource pool of the previous transmission preamble sequence (also referred to as the RACH resource pool when the last random access succeeds). At the same time, the MAC layer of the terminal device can increase the power of one step as the transmission power according to the transmission power of the previous transmission preamble sequence according to the step size of the power climbing. Similarly, the MAC layer of the terminal device transmits the transmission power and the selected RACH resource to the PHY layer of the terminal device, so that the PHY layer of the terminal device can use the transmission power to perform random access on the selected RACH resource.

因此，终端设备的MAC层与终端设备的PHY层交互，以获得beam ID或index，可以进行随机接入过程，以便于获取有效的波束进行数据传输。Therefore, the MAC layer of the terminal device interacts with the PHY layer of the terminal device to obtain a beam ID or index, and a random access procedure can be performed to obtain an effective beam for data transmission.

应理解，在本申请实施例中，终端设备的MAC层与终端设备的PHY层交互，以获得beam ID或index，也可以单独实施，以应用到其他场景中，并不限于应用在终端设备的随机接入过程中。It should be understood that, in the embodiment of the present application, the MAC layer of the terminal device interacts with the PHY layer of the terminal device to obtain a beam ID or an index, which may be separately implemented to be applied to other scenarios, and is not limited to being applied to the terminal device. During random access.

图3示出了根据本申请另一实施例的用于传输数据的方法300的示意性流程图。该方法300可以由终端设备执行。例如，该终端设备可以是图1中的终端设备11、终端设备12或终端设备13。对应地，与该终端设备通信的网络设备可以是图1中的基站21。如图3所示，该方法300包括：FIG. 3 shows a schematic flow diagram of a method 300 for transmitting data in accordance with another embodiment of the present application. The method 300 can be performed by a terminal device. For example, the terminal device may be the terminal device 11, the terminal device 12 or the terminal device 13 in FIG. Correspondingly, the network device in communication with the terminal device may be the base station 21 in FIG. As shown in FIG. 3, the method 300 includes:

S310，终端设备向网络设备发送请求消息，并对所述请求消息的发送次数进行计数，所述请求消息用于请求恢复下行波束；S310. The terminal device sends a request message to the network device, and counts the number of times the request message is sent, where the request message is used to request to restore the downlink beam.

可选地，终端设备可以在一个或多个上行波束上，向网络设备发送请求消息，比如波束恢复请求(Beam Recovery Request，BRR)消息，以便于向网络设备请求恢复下行波束。可选地，终端设备可以通过全向天线向网络设备发送请求消息。进一步地，终端设备可以引入计数器，对所述请求消息的发送次数进行计数。计数器用于统计请求消息的发送次数。比如，对于一组上行波束，当终端设备发送了一个BRR时，终端设备可以对计数器进行加1。可选地，一组上行波束可以是通过波束扫描(beam sweeping)方式得到的波束。Optionally, the terminal device may send a request message, such as a Beam Recovery Request (BRR) message, to the network device on the one or more uplink beams to facilitate requesting the network device to recover the downlink beam. Optionally, the terminal device may send a request message to the network device by using the omnidirectional antenna. Further, the terminal device may introduce a counter to count the number of times the request message is sent. The counter is used to count the number of times the request message is sent. For example, for a group of uplink beams, when the terminal device sends a BRR, the terminal device can increment the counter by one. Optionally, a set of uplink beams may be beams obtained by beam sweeping.

可选地，比如，若终端设备只触发了(triggered)一个BRR，且没有其余的BRR被触发处于等待状态(pending状态)，此时将计数器记为0。这里，终端设备触发BRR与发送请求消息是不同的动作。其中，所述pending状态是指：当终端设备触发了至少一个 BRR，则可以认为该至少一个BRR处于等待状态。可选地，若所述pending状态被取消，则终端设备不会向网络设备发送请求消息。Optionally, for example, if the terminal device only triggers one BRR and no other BRR is triggered to wait (pending state), the counter is recorded as 0. Here, the terminal device triggers the BRR to be different from the send request message. The pending state refers to: when the terminal device triggers at least one BRR, the at least one BRR may be considered to be in a waiting state. Optionally, if the pending state is cancelled, the terminal device does not send a request message to the network device.

也就是说，终端设备可以在请求消息中，携带终端设备确定的至少一个有效的下行波束的标识信息，以便于网络设备可以在所述至少一个下行波束中确定出最终传输数据所使用的下行波束。可选地，所述至少一个下行波束可以是同一个服务小区的波束，也可以是不同的服务小区的波束，对此不作限定。That is, the terminal device may carry the identification information of the at least one valid downlink beam determined by the terminal device in the request message, so that the network device can determine, in the at least one downlink beam, the downlink beam used for finally transmitting the data. . Optionally, the at least one downlink beam may be a beam of the same serving cell, or may be a beam of a different serving cell, which is not limited thereto.

或者，所述请求消息也可以包括至少一个第二下行服务波束的标识信息，所述至少一个第二下行服务波束是服务波束集中的失效波束。其中，服务波束集的所有波束可用于终端设备与网络设备之间的数据传输。可选地，所述至少一个第二下行服务波束可以是同一个服务小区的波束，也可以是不同的服务小区的波束，对此不作限定。Alternatively, the request message may also include identification information of at least one second downlink serving beam, where the at least one second downlink serving beam is a failed beam in the serving beam set. Wherein, all beams of the service beam set can be used for data transmission between the terminal device and the network device. Optionally, the at least one second downlink service beam may be a beam of the same serving cell, or may be a beam of a different serving cell, which is not limited thereto.

例如，若终端设备可以维护M个下行服务波束(可以理解为上面所述的服务波束集)，如果确定该M个下行服务波束中有N个下行服务波束失效，其中，N是小于或等于M的正整数，则终端设备向网络设备发送请求消息，该请求消息中可以携带N个失效的下行服务波束和终端设备确定的信号较好的波束(可以理解为上面所述的至少一个下行波束)。可选地，该请求消息可以是针对该N个下行服务波束发送的，或者，也可以不与该N个下行服务波束相关。For example, if the terminal device can maintain M downlink service beams (which can be understood as the service beam set described above), if it is determined that there are N downlink service beam failures among the M downlink service beams, where N is less than or equal to M A positive integer, the terminal device sends a request message to the network device, where the request message may carry N failed downlink service beams and a better signal determined by the terminal device (can be understood as at least one downlink beam as described above) . Optionally, the request message may be sent for the N downlink service beams, or may not be related to the N downlink service beams.

可选地，所述请求消息中还可以携带终端设备的服务波束集。Optionally, the request message may further carry a service beam set of the terminal device.

终端设备确定至少一个第一下行服务波束失效；The terminal device determines that the at least one first downlink service beam fails;

这里，服务波束可以指用于终端设备与网络设备之间数据传输的波束。服务波束可以包括上行服务波束和下行服务波束。Here, the service beam may refer to a beam used for data transmission between the terminal device and the network device. The service beam may include an uplink service beam and a downlink service beam.

可选地，所述至少一个第一下行服务波束可以是同一个服务小区的波束，也可以是不同的服务小区的波束，对此不作限定。Optionally, the at least one first downlink service beam may be a beam of the same serving cell, or may be a beam of a different serving cell, which is not limited.

可选地，终端设备可以对下行服务波束进行测量，根据测量结果得到下行波束的信号强度。终端设备可以根据下行服务波束的信号强度，确定至少一个下行服务波束(比如第一下行服务波束)失效(failure)。比如，若至少一个第一下行服务波束的信号强度低于或等于一定的阈值门限的一段时间之后，则终端设备可以认为该至少一个第一下行服务波束失效。Optionally, the terminal device may measure the downlink service beam, and obtain a signal strength of the downlink beam according to the measurement result. The terminal device may determine, according to the signal strength of the downlink service beam, that at least one downlink service beam (such as the first downlink service beam) fails. For example, if the signal strength of the at least one first downlink serving beam is lower than or equal to a certain threshold threshold, the terminal device may consider that the at least one first downlink serving beam is invalid.

例如，终端设备可以确定服务小区中的服务波束失效，或者，也可以确定激活的服务波束失效。For example, the terminal device may determine a service beam failure in the serving cell, or may also determine an activated service beam failure.

在本申请实施例中，终端设备在判断至少一个第一下行服务波束失效后，可以触发至少一个BRR，继而向网络设备发送触发的BRR，以请求恢复下行波束。In the embodiment of the present application, after determining that the at least one first downlink service beam fails, the terminal device may trigger at least one BRR, and then send the triggered BRR to the network device to request to recover the downlink beam.

可选地，在S310之前，终端设备可以接收网络设备发送的资源配置信息，该资源配置信息用于为终端设备的服务小区配置第一资源。可选地，该第一资源可以包括时域资源，频域资源，码域资源，空域资源中的至少一项。可选地，所述第一资源可以是主小区(PCell)或辅小区(SCell)的资源。Optionally, before S310, the terminal device may receive resource configuration information sent by the network device, where the resource configuration information is used to configure the first resource for the serving cell of the terminal device. Optionally, the first resource may include at least one of a time domain resource, a frequency domain resource, a code domain resource, and an airspace resource. Optionally, the first resource may be a resource of a primary cell (PCell) or a secondary cell (SCell).

可选地，终端设备可以在该第一资源上选择某一资源，向网络设备发送所述请求消息。Optionally, the terminal device may select a certain resource on the first resource, and send the request message to the network device.

S320，在所述发送次数未达到预设次数时，若所述终端设备接收到所述网络设备发送的响应消息，则停止发送所述请求消息，并接收所述网络设备通过所述响应消息指示的下行波束发送的数据；S320, when the number of times of sending does not reach the preset number of times, if the terminal device receives the response message sent by the network device, stopping sending the request message, and receiving, by the network device, the indication by using the response message Data sent by the downlink beam;

或者，在所述发送次数达到预设次数后，所述终端设备停止发送所述请求消息。Or, after the number of times of sending reaches a preset number of times, the terminal device stops sending the request message.

具体而言，在请求消息的发送次数小于或等于预设次数(比如，预设次数为预定义的最大传输次数)前，如果终端设备收到了网络设备发送的响应消息，那么可以停止发送请求消息，并接收所述网络设备通过响应消息指示的下行波束发送的数据(即与网络设备进行数据通信)；或者，在请求消息的发送次数大于或等于最大传输次数后，终端设备即使没有接收到网络设备发送的响应消息，也必须停止发送所述请求消息。Specifically, before the number of times the request message is sent is less than or equal to the preset number of times (for example, the preset number of times is a predefined maximum number of transmissions), if the terminal device receives the response message sent by the network device, the request message may be stopped. Receiving, by the network device, the data sent by the downlink beam indicated by the response message (that is, performing data communication with the network device); or, after the number of times the request message is sent is greater than or equal to the maximum number of transmissions, the terminal device does not receive the network. The response message sent by the device must also stop sending the request message.

这里，网络设备通过响应消息指示的“下行波束”是有效的波束，可以理解为网络设备确定的有效的下行波束，该下行波束与终端设备确定的“至少一个第一下行服务波束”的失效波束是不同的概念。换言之，网络设备通过响应消息指示的“下行波束”，是网络设备确定终端设备可以用于数据的传输波束。Here, the "downlink beam" indicated by the network device by the response message is a valid beam, which can be understood as a valid downlink beam determined by the network device, and the downlink beam and the "at least one first downlink service beam" determined by the terminal device are invalid. Beams are different concepts. In other words, the "downlink beam" indicated by the network device by the response message is a transmission beam that the network device determines that the terminal device can use for data.

可选地，所述预设次数是网络设备预先配置的，或者，协议预先规定的，以便于限制终端设备发送请求消息的次数。Optionally, the preset number of times is pre-configured by the network device, or the protocol is pre-defined to limit the number of times the terminal device sends the request message.

可选地，终端设备在收到响应消息时，可以对接收波束进行修改或调整操作，或者也可以不作修改或调整，以便于接收网络设备在至少一个下行波束发送的数据，其中，该至少一个下行波束是网络设备通过响应消息指示的。可选地，该数据包括下行控制面数据和/或用户面数据。Optionally, the terminal device may modify or adjust the receiving beam when receiving the response message, or may not modify or adjust, so as to receive data sent by the network device in the at least one downlink beam, where the at least one The downlink beam is indicated by the network device through a response message. Optionally, the data includes downlink control plane data and/or user plane data.

这里，所述“修改或调整操作”包括：(1)若接收波束的部分波束发生了变化，则终端设备根据响应消息对接收波束进行部分调整，比如，修改接收波束的相位或角度；(2)若接收波束全部发生变化，则终端设备根据响应消息对接收波束进行全部调整，比如，修改接收波束的相位或角度。或者，(3)若接收波束未发生变化，终端设备对接收波束的方向不进行调整或修改。应理解，这里只是以这3种情况为例进行说明，实际中可以有其他合理的调整或修改操作，并不对本申请实施例构成限定。Here, the “modification or adjustment operation” includes: (1) if a part of the beam of the receiving beam changes, the terminal device partially adjusts the receiving beam according to the response message, for example, modifying the phase or angle of the receiving beam; If all the receiving beams change, the terminal device performs all adjustments on the receiving beam according to the response message, for example, modifying the phase or angle of the receiving beam. Or, (3) if the receiving beam does not change, the terminal device does not adjust or modify the direction of the receiving beam. It should be understood that the above three cases are only taken as an example, and there may be other reasonable adjustment or modification operations in practice, and the embodiments of the present application are not limited.

可选地，网络设备发送的所述响应消息可以包括至少一个下行波束的标识信息，以便于向终端设备通知用于为终端设备服务的下行波束。这里，所述至少一个下行波束可以理解为终端设备用于更新终端设备的服务波束集的波束。Optionally, the response message sent by the network device may include identifier information of the at least one downlink beam, so as to notify the terminal device of the downlink beam used for serving the terminal device.

可选地，网络设备发送的所述响应消息也可以通过物理层信令或MAC CE进行发送。Optionally, the response message sent by the network device may also be sent by using physical layer signaling or a MAC CE.

可选地，终端设备在停止发送所述请求消息后，可以释放所述第一资源，不再通过发送请求消息，避免了发送不必要的请求消息，以节省终端的电能。Optionally, after the terminal device stops sending the request message, the terminal device may release the first resource, and no longer send a request message, thereby avoiding sending an unnecessary request message to save power of the terminal.

可选地，所述方法300还可以包括：Optionally, the method 300 may further include:

在所述发送次数达到预设次数后，所述终端设备向所述网络设备发送随机接入请求或者，所述终端设备确定无线链路失败，或者，所述终端设备进入空闲态，或者，所述终端设备发起无线资源控制RRC连接重建立过程。After the number of times of sending reaches a preset number of times, the terminal device sends a random access request to the network device, or the terminal device determines that the radio link fails, or the terminal device enters an idle state, or The terminal device initiates a radio resource control RRC connection re-establishment process.

具体而言，若请求消息的发送次数大于或等于最大传输次数，终端设备可以向网络设备发送随机接入请求，以便于请求所述网络设备为终端设备提供服务；或者，终端设备可以认为无线链路失败；或者，终端设备进入空闲态(idle)，释放终端设备的服务小区的上下文；或者，终端设备发起RRC连接重建立过程，其中，RRC连接重建立过程用于重建立RRC连接，以便重新开始数据传输。换言之，在所述发送次数达到预设次数后，终端设备可以进行实施这四种情况中的任意一项。或者，终端也可以进行其他可能的行为。Specifically, if the number of times the request message is sent is greater than or equal to the maximum number of transmissions, the terminal device may send a random access request to the network device, so as to request the network device to provide a service for the terminal device; or, the terminal device may consider the wireless chain If the terminal device enters an idle state (idle), the context of the serving cell of the terminal device is released; or the terminal device initiates an RRC connection re-establishment process, where the RRC connection re-establishment process is used to re-establish the RRC connection, so as to re-establish Start data transfer. In other words, after the number of transmissions reaches a preset number of times, the terminal device can perform any one of the four cases. Alternatively, the terminal can perform other possible actions.

可选地，在终端设备向网络设备发送请求消息前，所述方法还可以包括：Optionally, before the terminal device sends the request message to the network device, the method may further include:

也就是说，终端设备在确定至少一个第一下行服务波束失效后，可以触发至少一个恢复请求。这里，“至少一个恢复请求的触发”可以指处于pending状态的至少一个BRR。终端设备可以根据或基于触发的至少一个BRR，向网络设备发送请求消息。其中，所述pending状态是指：当终端设备触发了至少一个BRR，则可以认为该至少一个BRR处于等待状态。可选地，若所述pending状态被取消，则终端设备不会向网络设备发送请求消息。That is, the terminal device may trigger at least one recovery request after determining that the at least one first downlink service beam fails. Here, "trigger of at least one resume request" may refer to at least one BRR in a pending state. The terminal device may send a request message to the network device according to or based on the triggered at least one BRR. The pending state refers to: when the terminal device triggers at least one BRR, the at least one BRR may be considered to be in a waiting state. Optionally, if the pending state is cancelled, the terminal device does not send a request message to the network device.

可选地，只要还有一个BRR处于pending状态而且还未被取消，那么终端设备可以继续向网络设备发送请求消息。Optionally, the terminal device may continue to send the request message to the network device as long as another BRR is in the pending state and has not been cancelled.

具体而言，如果终端设备接收到网络设备发送的响应消息，那么可以取消触发的至少一个恢复请求(即取消所有处于pending状态的BRR)；或者，如果终端设备发送请求消息的发送次数超过或达到最大传输次数，那么也可以取消至少一个恢复请求。Specifically, if the terminal device receives the response message sent by the network device, the triggered at least one recovery request may be cancelled (ie, all BRRs in the pending state are cancelled); or if the number of times the terminal device sends the request message exceeds or reaches The maximum number of transmissions, then at least one recovery request can also be cancelled.

可选地，在所述网络设备为所述终端设备配置了非连续接收DRX机制的情况下，所述方法还包括：Optionally, in a case that the network device is configured with the discontinuous receiving DRX mechanism for the terminal device, the method further includes:

在所述终端设备向网络设备发送下行波束的所述请求消息之后，且在所述终端设备取消触发的至少一个所述恢复请求之前，所述终端设备监听下行信道，以接收所述网络设备发送的所述响应消息。After the terminal device sends the request message of the downlink beam to the network device, and before the terminal device cancels the at least one of the recovery requests, the terminal device monitors the downlink channel to receive the network device to send The response message.

具体而言，如果终端设备配置了非连续接收(Discontinuous Reception，DRX)机制，则终端设备在向网络设备发送下行波束的所述请求消息之后，且在所述终端设备取消至少一个所述恢复请求之前(即至少一个所述恢复请求还处于pending状态)，所述终端设备可以保持DRX机制的激活期，监听下行信道，比如，物理下行控制信道(Physical Downlink Control CHannel，PDCCH)，以接收所述网络设备发送的所述响应消息。具体比如，终端设备可以监听服务小区的下行服务波束集的PDCCH，或者，可以监听至少一个服务小区的下行服务波束集的PDCCH，以便于获取响应消息。Specifically, if the terminal device is configured with a discontinuous reception (DRX) mechanism, the terminal device sends the request message of the downlink beam to the network device, and cancels at least one of the recovery requests at the terminal device. Before (ie, at least one of the recovery requests is still in the pending state), the terminal device may maintain an activation period of the DRX mechanism, and listen to a downlink channel, such as a Physical Downlink Control CHannel (PDCCH), to receive the The response message sent by the network device. For example, the terminal device may listen to the PDCCH of the downlink service beam set of the serving cell, or may listen to the PDCCH of the downlink service beam set of the at least one serving cell, in order to obtain a response message.

若所述终端设备监听到所述网络设备发送的响应消息，所述终端设备停止监听所述下行信道；或者，If the terminal device listens to the response message sent by the network device, the terminal device stops listening to the downlink channel; or

若所述发送次数达到预设次数，且所述终端设备未监听到网络设备发送的所述响应消息，所述终端设备停止监听所述下行信道。If the number of transmissions reaches a preset number of times, and the terminal device does not listen to the response message sent by the network device, the terminal device stops listening to the downlink channel.

具体而言，在DRX机制中，若终端设备成功监听到了响应消息，则可以停止监听下行信道；若终端设备的请求消息的发送次数达到最大传输次数，但是终端设备仍未监听到响应消息，则仍然停止监听所述下行信道。Specifically, in the DRX mechanism, if the terminal device successfully detects the response message, it may stop listening to the downlink channel; if the number of times the request message of the terminal device is sent reaches the maximum number of transmissions, but the terminal device still does not listen to the response message, The interception of the downlink channel is still stopped.

上面描述了终端设备可以通过请求消息告知网络设备：终端设备确定至少一个下行波束有效的情况。下面将描述该至少一个下行波束是否有效可以通过其他方式告知给网络设备。It has been described above that the terminal device can inform the network device by the request message that the terminal device determines that at least one downlink beam is valid. Whether the at least one downlink beam is valid or not can be otherwise notified to the network device.

可选地，作为一个实施例，在所述终端设备接收到所述网络设备发送的响应消息之前，所述方法还包括：Optionally, as an embodiment, before the receiving, by the terminal device, the response message sent by the network device, the method further includes:

也就是说，终端设备可以通过MAC CE，携带终端设备确定的至少一个信号强度较好的下行波束的标识信息(比如，beam ID或Index)，以便于网络设备可以在所述至少一个下行波束中确定出最终传输数据所使用的下行波束。另外，终端设备发送所述MAC CE的传输资源可以是网络设备为终端设备配置的。可选地，所述请求消息中还可以携带终端设备的服务波束集。可选地，所述至少一个下行波束可以是同一个服务小区的波束，也可以是不同的服务小区的波束，对此不作限定。That is, the terminal device may carry, by using the MAC CE, at least one identification information (for example, beam ID or Index) of the downlink beam with better signal strength determined by the terminal device, so that the network device may be in the at least one downlink beam. Determine the downstream beam used to ultimately transmit the data. In addition, the transmission resource of the MAC CE sent by the terminal device may be configured by the network device for the terminal device. Optionally, the request message may further carry a service beam set of the terminal device. Optionally, the at least one downlink beam may be a beam of the same serving cell, or may be a beam of a different serving cell, which is not limited thereto.

或者，所述MAC CE中也可以包括至少一个第二下行服务波束的标识信息，所述至少一个第二下行服务波束是服务波束集中的失效波束。其中，服务波束集的所有波束可用于终端设备与网络设备之间的数据传输。可选地，所述至少一个第二下行服务波束可以是同一个服务小区的波束，也可以是不同的服务小区的波束，对此不作限定。Alternatively, the MAC CE may also include identification information of at least one second downlink serving beam, where the at least one second downlink serving beam is a failed beam in the serving beam set. Wherein, all beams of the service beam set can be used for data transmission between the terminal device and the network device. Optionally, the at least one second downlink service beam may be a beam of the same serving cell, or may be a beam of a different serving cell, which is not limited thereto.

综上，终端设备可以通过请求消息或MAC CE，向网络设备通知至少一个下行波束，或者至少一个第二下行服务波束，或者终端设备的服务波束集。网络设备可以在至少一个下行波束中，选择出一个或多个下行波束向终端设备回复响应消息。In summary, the terminal device may notify the network device of the at least one downlink beam, or the at least one second downlink service beam, or the service beam set of the terminal device, by using the request message or the MAC CE. The network device may select one or more downlink beams to reply to the terminal device in response to the at least one downlink beam.

在本申请实施例中，网络设备可以在至少一个下行波束(即上述通过请求消息或MAC CE中携带的标识信息的至少一个下波束)中选择或确定出一个或多个有效的下行波束。或者，网络设备可以根据所述至少一个第二下行服务波束(即上述通过请求消息或 MAC CE中携带的标识信息的至少一个失效的服务下行波束)，在终端设备的服务波束集中，选择或确定出一个或多个有效的下行波束。In this embodiment of the present application, the network device may select or determine one or more valid downlink beams in the at least one downlink beam, that is, the at least one downlink beam that passes the request message or the identifier information carried in the MAC CE. Alternatively, the network device may select or determine in the service beam set of the terminal device according to the at least one second downlink service beam, that is, the at least one failed service downlink beam that passes the request message or the identifier information carried in the MAC CE. One or more valid downstream beams are present.

因此，在本申请实施例中，终端设备通过向网络设备发送请求消息，并对所述请求消息的发送次数进行计数；在所述发送次数达到预设次数前，若所述终端设备接收到所述网络设备发送的响应消息，则停止发送所述请求消息，并接收网络设备通过所述响应消息指示的下行波束发送的数据；或者，在所述发送次数达到预设次数后，所述终端设备停止发送所述请求消息，能够进行波束恢复，进一步地，避免了不必要的请求消息的发送，节省终端设备的功耗。Therefore, in the embodiment of the present application, the terminal device sends a request message to the network device, and counts the number of times the request message is sent; if the number of times the transmission reaches a preset number of times, if the terminal device receives the The response message sent by the network device stops transmitting the request message, and receives data sent by the network device by using the downlink beam indicated by the response message; or, after the number of times of sending reaches a preset number of times, the terminal device The transmission of the request message is stopped, and beam recovery can be performed. Further, unnecessary transmission of the request message is avoided, and power consumption of the terminal device is saved.

在本申请实施例的方法200中，终端设备可以接收网络设备发送的第一控制信息，该第一控制信息用于指示至少一个上行波束是否有效。进一步地，本申请还提供了一个实施例，终端设备可以预先向网络设备发送第一信号(比如同步信号)，使得网络设备可以根据第一信号确定出一些信号质量较好的波束。下文会结合图6详细描述该实施例。应理解，该实施例可以与前文的实施例结合使用，也可以单独使用，本对此不作限制。In the method 200 of the embodiment of the present application, the terminal device may receive the first control information that is sent by the network device, where the first control information is used to indicate whether the at least one uplink beam is valid. Further, the present application further provides an embodiment, the terminal device may send a first signal (such as a synchronization signal) to the network device in advance, so that the network device can determine some beams with better signal quality according to the first signal. This embodiment will be described in detail below in conjunction with FIG. It should be understood that this embodiment may be used in combination with the foregoing embodiments, or may be used alone, and is not limited thereto.

图4示出了根据本申请另一实施例的用于传输数据的方法400的示意性流程图。该方法400可以由终端设备执行。例如，该终端设备可以是图1中的终端设备11、终端设备12或终端设备13。对应地，与该终端设备通信的网络设备可以是图1中的基站21。如图4所示，该方法400包括：FIG. 4 shows a schematic flow diagram of a method 400 for transmitting data in accordance with another embodiment of the present application. The method 400 can be performed by a terminal device. For example, the terminal device may be the terminal device 11, the terminal device 12 or the terminal device 13 in FIG. Correspondingly, the network device in communication with the terminal device may be the base station 21 in FIG. As shown in FIG. 4, the method 400 includes:

S410，终端设备向网络设备发送请求消息，并对所述请求消息的发送次数进行计数，所述请求消息用于请求恢复下行波束；S410: The terminal device sends a request message to the network device, and counts the number of times the request message is sent, where the request message is used to request to restore the downlink beam.

可选地，终端设备可以在一个或多个上行波束上，向网络设备发送请求消息，比如波束失败恢复请求(Beam failure Recovery Request，BRR)消息，以便于向网络设备请求恢复下行波束。可选地，所述请求消息还可以用于向网络设备通知终端设备发生波束失败。可选地，终端设备可以通过全向天线向网络设备发送请求消息。进一步地，终端设备可以引入计数器，对所述请求消息的发送次数进行计数。换言之，在本申请实施例中，计数器用于统计BRR的发送次数。比如，对于一组上行波束，当终端设备发送了一个BRR时，终端设备可以对计数器进行加1。可选地，一组上行波束可以是通过波束扫描(beam sweeping)方式得到的波束。Optionally, the terminal device may send a request message, such as a Beam Failure Recovery Request (BRR) message, to the network device on one or more uplink beams, in order to request the network device to recover the downlink beam. Optionally, the request message may be further used to notify the network device that the terminal device has a beam failure. Optionally, the terminal device may send a request message to the network device by using the omnidirectional antenna. Further, the terminal device may introduce a counter to count the number of times the request message is sent. In other words, in the embodiment of the present application, the counter is used to count the number of transmissions of the BRR. For example, for a group of uplink beams, when the terminal device sends a BRR, the terminal device can increment the counter by one. Optionally, a set of uplink beams may be beams obtained by beam sweeping.

可选地，所述请求消息可以通过物理上行控制信道PUCCH或用于传输前导序列Preamble的物理信道进行传输的。其中，若所述请求消息在PUCCH传输，则所述请求消息为上行控制信令；若所述请求消息在用于传输前导序列的物理信道中传输，则所述请求消息为前导序列。需要说明的是，如果终端设备同时配置物理上行控制信道PUCCH和用于传输前导序列Preamble的物理信道的资源，那么终端设备优先选择通过物理上行控制信道PUCCH发送请求消息。Optionally, the request message may be transmitted by using a physical uplink control channel PUCCH or a physical channel for transmitting a preamble sequence Preamble. The request message is uplink control signaling if the request message is transmitted on a PUCCH; and the request message is a preamble sequence if the request message is transmitted in a physical channel used for transmitting a preamble sequence. It should be noted that, if the terminal device simultaneously configures the physical uplink control channel PUCCH and the resource of the physical channel for transmitting the preamble sequence Preamble, the terminal device preferentially selects to send the request message through the physical uplink control channel PUCCH.

可选地，比如，若终端设备只触发了(triggered)一个BRR，且没有其余的BRR被触发处于等待状态(pending状态)，此时将计数器记为0。这里，终端设备触发BRR与发送请求消息是不同的动作。其中，所述pending状态是指：当终端设备触发了至少一个BRR，则可以认为该至少一个BRR处于等待状态。可选地，若所述pending状态被取消，则终端设备不会向网络设备发送请求消息。Optionally, for example, if the terminal device only triggers one BRR and no other BRR is triggered to wait (pending state), the counter is recorded as 0. Here, the terminal device triggers the BRR to be different from the send request message. The pending state refers to: when the terminal device triggers at least one BRR, the at least one BRR may be considered to be in a waiting state. Optionally, if the pending state is cancelled, the terminal device does not send a request message to the network device.

可选地，若终端设备配置了第一定时器，那么终端设备在第一定时器运行期间，即使终端设备已经触发了BRR，也不会触发终端设备通过第一定时器关联的至少一个波束或至少一个小区向网络设备发送BRR，或者，所述终端设备不会触发终端设备向网络设备发送BRR。可选地，第一定时器的时长是由网络设备预先配置的或协议预先规定的。Optionally, if the terminal device is configured with the first timer, the terminal device does not trigger the terminal device to pass at least one beam associated with the first timer or even if the terminal device has triggered the BRR during the running of the first timer.

After the BRR is sent, the second timer is started or restarted, and the duration of the second timer may be configured by the network. The beam recovery triggered by the tenth timer timeout does not trigger the terminal device to send a beam recovery request to the network device.

需说明的是，所述终端设备在确定根据所述上行传输资源生成的第一协议层的协议数据单元中包括填充比特Padding bits时，则将填充Padding的波束状态报告第一协议层控制信令携带在Padding bits中，还可以理解为，在所述上行传输资源分配后，若还存在用于传输填充Padding数据的资源时，则终端设备将填充数据的波束状态报告MAC CE携带在填充Padding比特中。需说明的是，MAC CE包括Padding MAC CE和非Padding MAC CE。其中非Padding MAC CE包括以下中的至少一项：功率余量报告(Power Headroom Report，PHR)MAC CE、C-RNTI MAC CE、PHR MAC CE、SPS确认MAC CE。It is to be noted that, when determining that the protocol data unit of the first protocol layer generated according to the uplink transmission resource includes padding bits, the terminal device reports the beam state of the padding to report the first protocol layer control signaling. It is also understood that, in the Padding bits, after the uplink transmission resource allocation, if there is still a resource for transmitting Padding data, the terminal device carries the beam state report MAC CE of the padding data in the padding Padding bit. in. It should be noted that the MAC CE includes Padding MAC CE and non-Padding MAC CE. The non-Padding MAC CE includes at least one of the following: a Power Headroom Report (PHR) MAC CE, a C-RNTI MAC CE, a PHR MAC CE, and an SPS Confirmation MAC CE.

其中，所述Padding bits可以理解为剩余资源，用于传输Padding的波束状态报告MAC CE的资源。所述剩余资源是指在所述上行传输资源包括的传输块大小中除去分配给逻辑信道中的数据和第一MAC CE之后剩余的资源。其中，第一MAC CE是指以下至少一项：(1)非填充padding波束状态报告MAC CE的MAC CE；(2)非padding波束状态报告MAC CE的MAC CE；(3)非padding的功率余量报告PHR MAC CE的MAC CE。BSR用于通知终端设备的缓冲区状态，PHR用于通知终端设备的功率余量。第一MAC还可以理解为非Padding的MAC CE。The Padding bits can be understood as the remaining resources used to transmit the resources of the Padding beam status report MAC CE. The remaining resources refer to resources remaining after the data allocated to the logical channel and the first MAC CE are removed from the transport block size included in the uplink transmission resource. The first MAC CE refers to at least one of the following: (1) a non-padded beam state report MAC CE MAC CE; (2) a non-padding beam state report MAC CE MAC CE; (3) a non-padding power balance The quantity reports the MAC CE of the PHR MAC CE. The BSR is used to notify the buffer status of the terminal device, and the PHR is used to notify the power headroom of the terminal device. The first MAC can also be understood as a non-Padding MAC CE.

举例来说，对于一个padding的波束状态报告MAC CE：如果还存在剩余资源，比如用于波束状态报告MAC CE的填充padding bits大于或等于波束状态报告MAC CE加上它的子头sub-header，那么终端设备可以触发生成一个padding的波束状态报告MAC CE(比如，所述填充的波束状态报告MAC CE)，并携带于Padding bits中。其中，Padding bits用于传输填充padding数据或Padding MAC CE。For example, for a padding beam state report MAC CE: if there are still remaining resources, such as padding bits for the beam state report MAC CE is greater than or equal to the beam state report MAC CE plus its sub-header, Then, the terminal device can trigger the generation of a padding beam state report MAC CE (for example, the filled beam state report MAC CE) and carry it in the Padding bits. Among them, Padding bits are used to transmit padding data or Padding MAC CE.

可选地，终端设备根据Padding bits的大小，确定是否可以传输Padding的波束状态报告。可选地，如果可以传输，则还需确定波束状态报告MAC CE的大小，并上报R个波束中优先级最高的U个波束的波束状态。其中，优先级最高的波束可以理解为波束的第一信号接收功率或第一信号接收质量最好的U个波束，或波束的路损最小的U个波束，或波束的PDCCH质量最好的U个波束，其中，R大于或等于U，U、R均为正整数，U，R可以由网络配置的或协议预先规定的。Optionally, the terminal device determines, according to the size of the Padding bits, whether the beam state report of the Padding can be transmitted. Optionally, if the transmission is possible, the beam state report MAC CE size is also determined, and the beam states of the U beams with the highest priority among the R beams are reported. The beam with the highest priority can be understood as the first signal received power of the beam or the U beams with the best reception quality of the first beam, or the U beams with the smallest path loss of the beam, or the U with the best PDCCH quality of the beam. Beams, where R is greater than or equal to U, U, R are positive integers, and U, R may be pre-defined by network configuration or protocol.

第一信号接收功率或第一信号接收质量的第一信号可以理解为以下至少一种：PSS、SSS、CSI-RS、DMRS。The first signal received power or the first signal received quality may be understood as at least one of the following: PSS, SSS, CSI-RS, DMRS.

可选地，如果padding bits不能传输波束状态报告MAC CE，那么终端设备可以上报截取波束状态报告，即只上报部分波束的波束状态，比如波束的参考信号接收功率或质量最好的部分波束的波束状态；或者，如果padding bits能传输长的波束状态报告MAC CE，那么终端设备传输长的波束状态报告MAC CE。Optionally, if the padding bits cannot transmit the beam state report MAC CE, the terminal device may report the intercepted beam status report, that is, only report the beam status of the partial beam, such as the beam reference signal received power or the beam with the best quality partial beam. State; or, if the padding bits can transmit a long beam status report MAC CE, the terminal device transmits a long beam status report MAC CE.

可选地，对于一个padding的波束状态报告，终端设备不会取消已经触发的普通波束状态报告或周期波束状态报告。其中，普通波束状态报告是由失败波束触发的，周期波束状态报告是由波束状态报告的周期定时器触发的。Optionally, for a padding beam state report, the terminal device does not cancel the normal beam state report or the periodic beam state report that has been triggered. The normal beam state report is triggered by the failed beam, and the periodic beam state report is triggered by the periodic timer of the beam state report.

应理解，在本申请实施例中，波束状态报告也可以理解为波束状态信息。It should be understood that in the embodiment of the present application, the beam status report may also be understood as beam status information.

可选地，如果MAC协议数据单元PDU中只包括Padding波束状态报告或周期波束状态报告，那么MAC不生成MAC PDU。Optionally, if only the Padding beam status report or the periodic beam status report is included in the MAC protocol data unit PDU, the MAC does not generate a MAC PDU.

S930，所述终端设备根据所述第一指示，向所述网络设备发送所述第一协议层的PDU，其中，第一协议层的PDU包括填充比特Padding bits，所述填充比特Padding bits携带波束状态报告第一协议层控制信令。S930.
