- a wireless transmitter having multiple antennas can form a narrow wireless signal that points in a specific direction (for example, beamforming).
- the width and direction of the beam can be flexibly adjusted by applying appropriate weights to each antenna element.
- Beamforming can be either digital or analog.
- each antenna element has a separate baseband module, each antenna unit can independently control the amplitude and phase of the signal transmitted thereon, and thus, the digital beam can be narrowband (eg, have a ratio of total a narrower bandwidth of the system).
- Different digital beams can be multiplexed in the time or frequency domain.
- multiple antenna elements share the same digital baseband module, with each antenna unit having a separate phase shifter. The signal sent by each antenna unit can only be adjusted on the transmit phase shift (no amplitude adjustment is possible). Therefore, the analog beam is broadband and can only be multiplexed in the time domain.
- analog beamforming it can be applied to base stations in a wireless communication system, and can also be used for a UE.
- the analog beamforming of the uplink transmission can be obtained by the base station or the UE.
- the first mode if the correspondence between the downlink (DL)/uplink (UL) beam of the UE is established (for example, the reciprocity of the uplink and downlink beams is established), the UE may The DL Rx beam (downlink receive beam) derives its optimal UL Tx beam (uplink transmit beam, also referred to as uplink transmission characteristics), and the UE can automatically obtain the optimal UL Tx beam.
- the UE In order for the UE to be able to derive the UL Tx beam, the UE needs to know the downlink signal used to infer the DL Rx beam.

- SSB Synchronization Signal Block
- the second mode if the beam correspondence of the DL/UL on the UE side is not established, the UE cannot acquire the UL Tx beam through the DL signal, and the gNB is required to perform measurement and selection of the UL signal.
- the UE may send a set of uplink reference signals, and different uplink reference signals are transmitted using different UL Tx beams, which enables the gNB to use these uplink reference signals for uplink measurement and select an optimal transmit beam. Note that this method is applicable regardless of whether the correspondence between the uplink and downlink beams of the UE is established.
- the gNB needs to firstly semi-statically configure or dynamically trigger a reference signal (RS) resource sent by a group of UEs.
- RS reference signal
- the gNB After receiving the RSs sent by the UE, the gNB sends an indication of the RS resources (eg, RS resources). Serial number) to the UE. In this way, the UE can use the transmit beam of the RS resource indicated by the gNB to ensure the transmission performance.
- RS resources eg, RS resources. Serial number

- the indication information may be an indication for pointing to other types of RS resources (eg, DL reference signal or UL reference signal, CSI-RS, SSB, etc.).
- the gNB and the UE need to know in advance the bit width of the SRI and the RS resource corresponding to each SRI indication state.
- Each SRI may correspond to an RS resource, or a group of RS resources.
- the SRI for indicating the UL Tx beam can be used for the UL signal (for example, SRS), and can also be used for the uplink channel (for example, Physical Uplink Shared Channel (PUSCH), Physical Uplink Control Channel (Physical). Uplink Control Channel, PUCCH, etc.).
- SRS Physical Uplink Shared Channel

- the relationship between the transmission timing of the AP-SRS (for example, slot n1 (slot n1)) and the start timing of the transmission beam of the AP-SRS applied to the target SRS resource (for example, slot n2) needs to be defined in advance. For example: fixed, or configuration message through high-level signaling of the target SRS and/or source SRS, or by dynamic indication (either an independent signal or the same signal as the dynamic signal triggering the AP-SRS).

- SRS resources for example: an SRS resource set.
- the UL Tx beam is determined by the UE, or the UL Tx beam is determined by the gNB and signaled to the UE.

- the periodic PUCCH used for periodic channel state information (CSI) reporting must start at the time after the RRC configuration of the PUCCH resource, which may precede the MAC-CE activation of the UL beam, which will result in uplink. The problem of unclear transmission characteristics.
- Scenario 3 After receiving an RRC reconfiguration message, before receiving the associated MAC-CE activation information.

下面将结合本公开实施例中的附图,对本公开实施例中的技术方案进行清楚、完整地描述,显然,所描述的实施例是本公开一部分实施例,而不是全部的实施例。基于本公开中的实施例,本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例,都属于本公开保护的范围。
本公开的说明书和权利要求书中的术语“包括”以及它的任何变形,意图在于覆盖不排他的包含,例如,包含了一系列步骤或单元的过程、方法、系统、产品或设备不必限于清楚地列出的那些步骤或单元,而是可包括没有清楚地列出的或对于这些过程、方法、产品或设备固有的其它步骤或单元。此外,说明书以及权利要求中使用“和/或”表示所连接对象的至少其中之一,例如A和/或B,表示包含单独A,单独B,以及A和B都存在三种情况。
在本公开实施例中,“示例性的”或者“例如”等词用于表示作例子、例证或说明。本公开实施例中被描述为“示例性的”或者“例如”的任何实施例或设计方案不应被解释为比其它实施例或设计方案更优选或更具优势。确切而言,使用“示例性的”或者“例如”等词旨在以具体方式呈现相关概念。
为了更好的理解的本公开实施例的技术方案,首先介绍以下技术点:
(1)一个有多根天线的无线发射机(例如:下一代基站(next generation node base station,gNB))可以形成一个较窄的指向特定方向(例如:波束赋形)的无线信号。波束的宽度和方向可以通过在每个天线单元应用合适的权值来灵活地调整。波束赋形可以是数字域或是模拟域的。
对于数字波束赋形,每个天线单元具有单独的基带模块,每个天线单元可以独立地控制在其上传输的信号的幅度和相位,因此,数字波束可以是窄带的(例如:具有比总的系统带宽更窄的带宽)。不同的数字波束可以在时域或频域进行复用。对于模拟波束赋形,多个天线单元共享同一个数字基带模块,每个天线单元具有独立的相移器。每个天线单元发送的信号只能在发送相移上进行调整(不能进行幅度调整)。因此,模拟波束是宽带的,只能在时间域上进行复用。
对于模拟波束赋形,可以应用于无线通信系统中的基站,也可以用于UE。对于从UE到基站的上行链路传输,上行传输的模拟波束赋形可以通过基站或者UE获得。
第一种方式:如果在UE侧下行链路(Downlink,DL)/上行链路(Uplink,UL)的波束的对应关系是成立的(例如:上下行波束的互易性成立),UE可以根据DL Rx波束(下行链路接收波束)推出其最优的UL Tx波束(上行链路发送波束,也可称为上行传输特性),则UE可以自动地获得最优的UL Tx波束。为了使得UE可以推出UL Tx波束,UE需要知道用来推测DL Rx波束的下行信号。这个(或这些)下行信号可以是高层信号预配置的,或是网络侧指示给UE的。这样的一些下行信号的示例如:5G系统中的信道状态信息参考信号(Channel State Information-Reference Signal,CSI-RS),同步信号块(Synchronization Signal Block,SSB)。
第二种方式:如果在UE侧DL/UL的波束对应关系是不成立的,UE不 能通过DL信号获取UL Tx波束,而需要gNB进行UL信号的测量和选择。例如,UE可以发送一组上行参考信号,不同的上行参考信号使用不同的UL Tx波束进行发送,这使得gNB可以利用这些上行参考信号进行上行测量并选择最优的发送波束。注意无论UE的上行和下行波束间的对应关系是否成立,这种方式都适用。gNB需要首先半静态地配置或者动态地触发一组UE发送的参考信号(reference signal,RS)资源,接收到UE发送的这些RS后,gNB发送一个其倾向的RS资源指示(例如:RS资源的序号)给UE。这样UE就可以使用gNB指示的其倾向的RS资源的发送波束,以保证传输性能。一种UL信号的示例如第五代通信技术(5G)系统中的探测参考信号(Sounding Reference Signal,SRS)。
以上两种方式都可以独立地进行应用,或者同时使用。基站(下文以gNB为例)可以通过一个指示信息来指示其倾向的RS资源。
在本公开实施例中,gNB用于指示的其倾向的RS资源的指示信息,可以以探测参考资源指示(Sounding reference resource indicator,SRI)为例来进行阐述。需要说明的是,虽然在本公开实施例中,以SRI为例来进行阐述,无论指示信息以何种方式命名,都在本公开的范畴内。例如:指示信息可以为用于指向其他类型的RS资源(例如:DL参考信号或UL参考信号,CSI-RS,SSB等)的指示。gNB和UE需要预先知道SRI的比特宽度和每个SRI指示状态对应的RS资源。每个SRI可能对应指示一个RS资源,或者一组RS资源。
需要说明的是,用于指示UL Tx波束的SRI可以用于UL信号(例如:SRS),也可用于上行信道(例如物理上行共享信道(Physical Uplink Shared Channel,PUSCH)、物理上行控制信道(Physical Uplink Control Channel,PUCCH)等)。
(2)关于SRS的介绍:
配置给一个UE的SRS资源从时间域传输行为的角度可以分为多种类型。对于周期的SRS(periodic SRS,P-SRS)和半持续的SRS(semi-persistent SRS,SP-SRS),其在时间上按照一定的周期图样(periodic pattern)进行传输。一个时间图样包含着特定的周期和特定的时间偏移。对于非周期的SRS (aperiodic SRS,下文中用AP-SRS或A-SRS表示),它可以动态地通过一个动态信号在任意时刻进行触发,而非遵循一个特定的周期传输图样。一个触发信令可以在一个特定的时间窗内触发一个时间点或多个时间点的SRS传输。该触发信令可以携带在用于UL grant(上行准许)或DL grant(下行准许)中的DCI(Downlink Control Information,下行控制信息)。
SRS可以用于不同的用途。一个第一类SRS可以用于gNB进行UL CSI(Channel State Information,信道状态信息)获取。用于CSI获取的SRS可以进行了或没有进行模拟波束赋形,如果没有模拟波束赋形,可以通过前面介绍的SRI进行波束指示。一个第二类SRS可以用于模拟波束训练,其中UE发送的多个SRS使用相同或不同的波束。类似的,UL Tx波束可以由gNB通过SRI指示。
一个(目标)SRS资源的UL发送波束可以通过另一个(源)SRS资源的指示来提供,UE可以假设目标SRS资源使用与源SRS资源相同的UL Tx波束。以下是一些可能的[源,目标]SRS的示例:
源SRS资源可以通过无线资源控制(RRC)和/或媒体接入控制层控制单元(Medium Access Control Control Element,MAC-CE)信令进行配置和/或激活/去激活。
[P/SP,AP]:一个AP-SRS(aperiodic SRS)的源SRS资源可以通过高层信令配置,或者通过用于AP SRS触发的grant(或者下行控制信息(DCI))动态触发。
[AP,AP]:一个AP-SRS(aperiodic SRS)的源SRS资源可以通过高层信令配置,或者通过用于AP SRS触发的grant(或者DCI信令)动态触发。
[AP,P/SP]:目标SRS的UL Tx波束可以基于源AP-SRS的动态触发而动态变化。AP-SRS的发送时刻(例如:时隙n1(slot n1))和该AP-SRS的发送波束应用于目标SRS资源(例如:slot n2)的起始时刻之间的关系需要预先定义。例如:固定,或者通过目标SRS和/或源SRS的高层信令的配置消息,或者通过动态指示(可以是一个独立的信号,或者与触发AP-SRS的动态信号为同一信号)。
一个SRS资源集可以包括一个或多个SRS资源。5G中的SRS可以具有 多种用途,例如用于UL CSI获取(数字波束赋形),和/或UL发送波束管理(模拟波束赋形):
用于UL CSI获取(数字波束赋形)的SRS可以通过进行了模拟波束赋形的传输或者进行不进行模拟波束赋形的传输,SRS的UL Tx波束可以基于前面介绍的任何一种方式进行确定。
用于UL波束管理(模拟波束赋形)的SRS可以用于不同的目的,例如:P2和P3,其中,P2表示gNB的Rx(接收)波束扫描,其要求UE使用相同的UL Tx波束发送多个SRS资源(例如:一个SRS资源集)。UL Tx波束由UE确定,或者UL Tx波束由gNB确定并通过信令指示给UE。P3表示UE侧的Tx波束扫描,其需要UE使用不同的UL Tx波束发送多个SRS资源(例如:一个SRS资源集)。UL Tx波束可以由UE确定,或者由gNB指示。
(3)关于PUSCH:
PUSCH的传输是基站调度的,因此,PUSCH的上行传输特性可以通过SRI动态指示。SRI可以伴随着PUSCH的调度进行指示,即,每个PUSCH的传输总是伴随着一个与之对应的SRI波束指示。SRI可以在触发PUSCH的同一个UL准许中指示,也可以通过一个其他的L1信号指示。作为一种实现方式,一个波束指示用于UE进行多个PUSCH的传输,例如,在多个时隙进行传输。在这种情况下,携带SRI的L1信号可能需要指示多个PUSCH的位置(例如:指示它们的时隙编号,起始位置,每个生效的SRI的持续时间,或者一个SRI的激活/去激活信息的生效时间等)。
(4)关于PUCCH:
PUCCH可用来传输上行控制信息,包括但不限于:下行数据传输的确认/否认(ACK/NAK)相应,DL信道状态信息(channel state information,CSI),以及DL波束测量结果等。
一个UE可以被配置一个或多个PUCCH资源。每个PUCCH资源为一组时间频率资源的配置,以及一些其他可能的参数,例如PUCCH的格式(format),序列等。一个PUCCH信号的上行传输波束可以是动态指示或者半静态配置的。当一个PUCCH信号为半静态配置的时候,一个特定的PUCCH资源的发送波束(Tx beam)是基站半静态地配置的。一种方式是通过RRC 信号为每个PUCCH资源配置一组包含N个候选发送波束中的发送波束,其中N≥1。如果N=1,通过RRC信号为PUCCH配置的波束无需进一步地激活或者去激活,可以直接用于PUCCH。如果N≥1,可以通过额外的DL控制信号(如MAC-CE信息或动态信号)来为PUCCH从RRC信号配置的N个波束中选择一个发送波束。接收到MAC-CE(MAC-CE通过PDSCH携带)后,UE发送一个确认相应(ACK)给基站,以确认正确接收到了MAC-CE激活信息。基站接收到ACK信息后,间隔一个预设的P个时隙的时间间隔,基站和UE都假设MAC-CE携带的激活波束当前是生效的,并开始使用该激活波束进行通信。去激活的过程与上述激活过程类似。该流程的一个示意图如图1所示。
下面结合附图介绍本公开的实施例。本公开实施例提供的数据传输方法和设备可以应用于无线通信系统中。该无线通信系统可以为采用5G系统,或者演进型长期演进(Evolved Long Term Evolution,eLTE)系统,或者后续演进通信系统。参考图2,为本公开实施例提供的一种无线通信系统的架构示意图。如图2所示,该无线通信系统可以包括:网络侧设备20和用户设备,例如用户设备记做UE 21,UE 21可以与网络侧设备20通信。在实际应用中上述各个设备之间的连接可以为无线连接,为了方便直观地表示各个设备之间的连接关系,图2中采用实线示意。
需要说明的是,上述通信系统可以包括多个UE,网络侧设备和可以与多个UE通信(传输信令或传输数据)。
本公开实施例提供的网络侧设备可以为基站,该网络侧设备可以为通常所用的基站,也可以为演进型基站(evolved node base station,eNB),还可以为5G系统中的网络侧设备(例如下一代基站(next generation node base station,gNB)或发送和接收点(transmission and reception point,TRP))等设备。
本公开实施例提供的用户设备可以为手机、平板电脑、笔记本电脑、超级移动个人计算机(Ultra-Mobile Personal Computer,UMPC)、上网本或者个人数字助理(Personal Digital Assistant,PDA)等。
本公开实施例中的波束可以为模拟波束、数字波束,或模拟/数字混合波 束,也可以对应于预编码、模拟预编码、数字预编码等。
参见图3,图中示出根据本公开实施例的数据传输方法的流程,该方法的执行主体为UE,具体包括步骤301至302。

在本公开实施例中,第一信号可以为物理上行共享信道(Physical Uplink Shared Channel,PUSCH)、物理上行控制信道(Physical Uplink Control CHannel,PUCCH)、探测参考信号(Sounding Reference Signal,SRS)、随机接入信道(Random Access Channel,RACH)或其他类型的信号。
在本公开实施例中,上行传输特性是指UE使用的一种传输样式(transmission format)。虽然本文中使用上行发送波束作为上行传输特性的一种实施例的示例,需要说明的是,其他的传输特性(不同于UL波束,或者作为UL波束的补充,如上行传输模式(transmission scheme))也同样适用,为便于描述,此处没有针对其他传输特性展开说明。
步骤302、当所述网络侧设备没有清晰地指示所述第一信号的第一上行传输特性时,确定所述第一信号的实际的第一上行传输特性,通过所述第一上行传输特性发送第一信号,或者当所述网络侧设备没有清晰地指示所述第一信号的第一上行传输特性时,不进行所述第一信号的发送。

如果接收到了所述第三指示信息,则认为需要使用第一上行传输特性进行所述第一信号的传输,否则不使用第一上行传输特性进行所述第一信号的传输。
作为一个实施例,具体地,所述第二指示信息可以是一个显式的指示信息。例如,所述第二指示信息包含两个状态,两个状态分别代表使用第一上行传输特性进行第一信号的传输和不使用第一上上行传输特性进行第一信号的传输。如下图所示:
第二指示信息 | 代表的含义 |
0 | 使用第一上行传输特性进行第一信号的传输 |
1 | 不使用第一上行传输特性进行第一信号的传输 |
当然,所述第二指示信息也可以包含多个状态,其中一部分状态对应于是否使用第一上行传输特性进行第一信号的传输。
作为另一个实施例,具体地,所述第二指示信息可以是一个隐式的指示信息。例如,与所述第一上行传输特性相关联的信号指示信息,例如网络设备通过向终端指示了与所述第一信号相关联的第二信号来指示与所述第一信号相对应的第一上行传输特性,所述第一信号相对应的上行传输特性通过所述第二信号来确定。举例来说,假设所述第一上行传输特性为上行发送波束,所述第一信号为SRS信号,所述第二信号为CSI-RS信号,所述第二指示信息为与所述第一信号相关联的所述第二信号的指示。若与所述SRS相关联的CSI-RS为进行了波束赋形的CSI-RS,则认为所述网络设备向终端指示使用第一上行传输特性进行第一信号的传输;若与所述SRS相关联的CSI-RS没有进行波束赋形,则认为所述网络设备向终端指示不使用第一上行传输特性进行第一信号的传输
作为一个实施例,具体地,第三指示信息可以是一个与第一信号相关联的一个第三信号。若网络设备为终端指示了所述第三信号,则所述终端认为所述网络设备指示了终端使用第一上行传输特性进行第一信号的传输。若所述终端没有获得第三信号,则认为网络设备没有向终端指示使用第一上行传输特性进行第一信号的传输。
方式三、若没有接收到不再使用第一上行传输特性进行所述第一信号传输的第四指示信息,使用第一上行传输特性进行所述第一信号的传输,否则,不使用第一上行传输特性进行所述第一信号的传输。
与第三指示信息类似,所述第四指示信息也可以是显式地指示方式,或者为隐式的指示方式。
在本公开实施例中,可以通过以下方式确定所述第一信号的实际的第一上行传输特性:
方式1:根据下行接收信号确定所述第一信号的第一上行传输特性;或者,
方式2:确定所述第一信号的实际的第一上行传输特性与第三信号的第一上行传输特性相同。
对于方式1,可选地,所述下行信号为CSI-RS信号。根据所述网络设备为所述UE配置的CSI-RS信号确定所述第一信号的第一上行传输特性。所述CSI-RS信号可以为用于波束管理的CSI-RS信号,或者,用于第一上行传输特性确定的CSI-RS,或者用于下行CSI获取的CSI-RS等。以所述第一上行传输特性为上行发送波束为例,UE通过CSI-RS的下行接收波束可以获得一个上行发送波束,可以将该上行发送波束作为所述第一信号的上行发送波束。
对于方式1,可选地,所述下行信号可以为DMRS信号。
对于方式2,所述网络设备可以为UE指示与所述第一信号相关联的第三信号,UE根据与所述第一信号相关联的第三信号获得所述第一信号的第一上行传输特性。所述第三信号可以为一个上行信号或下行信号。
在本公开实施例中,在所述确定所述第一信号的实际的第一上行传输特性之后,所述方法还包括:将所述实际的第一上行传输特性的指示信息发送给网络侧设备,例如通过其他第一信号将所述实际的第一上行传输特性的指 示信息发送给网络侧设备;或者,通过所述第一信号将所述实际的第一上行传输特性的指示信息发送给网络侧设备。
其中,所述其他信号并不限制为第一信号,例如第一信号为PUSCH,所述其他信号为PUCCH。所述其他信号也可以为其他第一信号类型的信号,例如第一信号为一个PUSCH,所述其他信号为另一个PUSCH。
进一步地,所述实际的第一上行传输特性的指示信息,包括以下任意一项:从所述网络侧设备为所述UE配置的多个用于波束管理的信道状态信息参考信号(CSI-RS)资源中指示一个或多个CSI-RS资源的指示信息;

以下给出一些上述情况对应的示例。
对于上述情况(i),以第一信号为PUSCH,第一上行传输特性为上行发送波束为例。
在一个示例中:基站向UE指示上行发送波束,所述上行发送波束用于所有的上行信号。只有UE获得了基站指示的上行发送波束,且该上行发送波束生效(该上行发送波束生效可以与基站指示上行发送波束的信令方式有关。例如,基站通过RRC信令配置上行发送波束,通过MAC-CE信令激活且到达生效时间后才认为该上行发送波束生效;再例如,基站通过DCI信令指示上行发送波束,UE对DCI指示的该上行发送波束解码后该上行发送波束就生效;再例如,基站向UE指示上行发送波束,到达生效时间后该上行发送波束才生效等等,注意上行发送波束的指示方式可以为直接指示或者通过参考信号指示的方式等)后,才认为UE获取到了有效的上行发送波束。若UE接收基站指示UE发送PUSCH的第一指示信息后,发送该第一指示信息对应的PUSCH时,基站未向UE发送上行发送波束的指示信息或者基站发送的关于上行发送波束的指示信息或重配置信息尚未生效,可以认为UE未获取到该第一指示信息对应的PUSCH的有效的上行发送波束。所述UE获取到的所有有效的第一上行传输特性中最近一次获取到的有效的第一上行传输特性是指所述UE获取到且生效了的第一上行传输特性中最近一次获取到且生效的第一上行传输特性。
在另一个示例中:基站向UE指示多种上行信号的上行发送波束。例如,指示PUSCH的上行发送波束以及SRS的上行发送波束。UE接收到发送PUSCH的第一指示信息,且发送该第一指示信息对应的PUSCH时,若基站未向UE发送上行发送波束的指示信息或者UE接收到了基站发送的关于PUSCH的上 行发送波束的指示信息或重配置信息,且该指示信息或重配置信息尚未生效,则认为UE未获取到该第一指示信息对应的PUSCH的有效的上行发送波束。所述UE获取到的所有有效的第一上行传输特性中最近一次获取到的有效的第一上行传输特性是指所述UE获取到的所有上行信号的有效的上行发送波束中最近一次获取到的有效的第一上行传输特性。例如,最近一次获取到的有效的上行发送波束为一个SRS的上行发送波束,则UE使用该SRS的上行发送波束发送这个PUSCH。
对于上述情况(ii),以第一信号为PUSCH,第一上行传输特性为上行发送波束为例。
在一个示例中:UE接收基站指示UE发送PUSCH的第一指示信息后,发送该第一指示信息对应的PUSCH时,若基站未向UE发送PUSCH的上行发送波束的指示信息或者基站发送的关于PUSCH的上行发送波束的配置信息或重配置信息尚未生效,则认为UE未获取到该第一指示信息对应的PUSCH的有效的上行发送波束。所述UE获取到的第一信号的所有有效的第一上行传输特性中最近一次获取到的有效的第一上行传输特性是指所述UE之前最近一次获取到的PUSCH的有效的上行发送波束。
对于上述情况(iii),以第一信号为PUSCH,第一上行传输特性为上行发送波束为例。
在一个示例中:UE接收基站指示UE发送PUSCH的第一指示信息后,发送该第一指示信息对应的PUSCH时,若UE未获取该PUSCH对应的有效的上行发送波束,则使用UE最近一次发送上行信号使用的上行发送波束。
对于上述情况(iv),仍以第一信号为PUSCH,第一上行传输特性为上行发送波束为例。
在一个示例中:UE接收基站指示UE发送PUSCH的第一指示信息后,发送该第一指示信息对应的PUSCH时,若UE未获取该PUSCH对应的有效的上行发送波束,则使用UE最近一次发送PUSCH使用的上行发送波束。
这样,接收网络侧设备发送的第一指示信息,所述第一指示信息用于指示所述UE发送第一信号;当所述网络侧设备没有清晰地指示所述第一信号的第一上行传输特性,确定所述第一信号的实际的第一上行传输特性,通过所 述第一上行传输特性发送所述第一信号,或者当所述网络侧设备没有清晰地指示所述第一信号的第一上行传输特性,不进行所述第一信号的发送,避免当上行传输特性指示不清晰时,用户设备自行决定上行传输特性,将有可能导致网络侧设备和用户设备的理解不一致,从而无法使用相对应的上行接收行为,从而影响系统性能的问题。
参见图4,图中示出根据本公开实施例的数据传输方法的流程,该方法的执行主体为网络侧设备,具体步骤如下:
步骤401、向UE发送第一指示信息,所述第一指示信息用于指示所述UE发送第一信号;
步骤402、当所述网络侧设备没有清晰地指示所述第一信号的第一上行传输特性时,确定与所述第一信号实际的第一上行传输特性所对应的接收方式,通过所述接收方式接收第一信号,或者当所述网络侧设备没有清晰地指示所述第一信号的第一上行传输特性时,不在为所述第一信号调度的资源上接收所述第一信号。
在本公开实施例中,可选地,所述方法还包括:向终端发送是否使用第一上行传输特性发送所述第一信号的指示信息:

方式二、发送第三指示信息。如果所述终端接收到了所述第三指示信息,则所述终端认为需要使用第一上行传输特性进行所述第一信号的传输,否则不使用第一上行传输特性进行所述第一信号的传输。
作为一个实施例,具体地,所述第二指示信息可以是一个显式的指示信息。例如,所述第二指示信息包含两个状态,两个状态分别代表使用第一上行传输特性进行第一信号的传输和不使用第一上上行传输特性进行第一信号的传输。如下图所示:
第二指示信息 | 代表的含义 |
0 | 使用第一上行传输特性进行第一信号的传输 |

当然,所述第二指示信息也可以包含多个状态,其中一部分状态对应于是否使用第一上行传输特性进行第一信号的传输。

作为一个实施例,具体地,第三指示信息可以是一个与第一信号相关联的一个第三信号。若网络设备为终端指示了所述第三信号,则所述终端认为所述网络设备指示了终端使用第一上行传输特性进行第一信号的传输。若所述终端没有获得第三信号,则认为网络设备没有向终端指示使用第一上行传输特性进行第一信号的传输。
方式三、发送第四指示信息,所述第四指示信息用于指示所述终端不再使用第一上行传输特性进行所述第一信号传输。所述终端若没有接收到第四指示信息,则使用第一上行传输特性进行所述第一信号的传输,否则,不使用第一上行传输特性进行所述第一信号的传输。
与第二指示信息和第三指示信息类似,所述第四指示信息也可以是显式地指示方式,或者为隐式的指示方式。

以下给出一些上述情况对应的示例。
对于上述情况(i),以第一信号为PUSCH,第一上行传输特性为上行发送波束为例。
在一个示例中:基站向UE指示上行发送波束,所述上行发送波束用于所有的上行信号。只有当基站指示了上行发送波束,且该上行发送波束生效(该上行发送波束生效有一些可能的情况,可以与基站指示上行发送波束的信令方式有关。例如,基站通过RRC信令配置上行发送波束,通过MAC-CE信令 激活且到达生效时间后才认为该上行发送波束生效;再例如,基站通过DCI信令指示上行发送波束,UE通过该DCI译码到该上行发送波束后该上行发送波束就生效;再例如,基站向UE指示上行发送波束,到达生效时间后该上行发送波束才生效等等)后,才认为基站向UE发送了有效的上行发送波束。若UE接收基站指示UE发送PUSCH的第一指示信息后,发送该第一指示信息对应的PUSCH时,基站未发送关于上行发送波束的指示信息或者基站发送的关于上行发送波束的指示信息或重配置信息尚未生效,则认为基站尚未向UE发送该第一指示信息对应的PUSCH的有效的上行发送波束。向UE发送的所有有效的第一上行传输特性中最近一次发送的有效的第一上行传输特性是指基站向UE发送的且生效了的第一上行传输特性中最近一次发送且生效的第一上行传输特性。
在另一个示例中:基站向UE指示多种上行信号的上行发送波束。例如,指示PUSCH的上行发送波束以及SRS的上行发送波束。UE接收到发送PUSCH的第一指示信息,且发送该第一指示信息对应的PUSCH时,基站未向UE发送PUSCH的上行发送波束的指示信息或者基站向UE发送的关于PUSCH的上行发送波束的指示信息或重配置信息尚未生效,则认为基站尚未向UE发送该第一指示信息对应的PUSCH的有效的上行发送波束。向UE发送的所有有效的第一上行传输特性中最近一次发送的有效的第一上行传输特性是指基站向UE发送的所有上行信号的有效的上行发送波束中最近一次发送的有效的第一上行传输特性。例如,最近一次发送的有效的上行发送波束为一个SRS的上行发送波束,则UE使用该SRS的上行发送波束发送这个PUSCH。
对于上述情况(ii),以第一信号为PUSCH,第一上行传输特性为上行发送波束为例。
在一个示例中:UE接收基站指示UE发送PUSCH的第一指示信息后,发送该第一指示信息对应的PUSCH时,若基站未向UE发送关于上行发送波束的指示信息或者基站向UE发送的关于PUSCH的上行发送波束的指示信息或重配置信息尚未生效,则认为基站尚未向UE发送该第一指示信息对应的PUSCH的有效的上行发送波束。向UE发送的所有有效的第一上行传输特性中最近一 次发送的有效的第一上行传输特性是指基站之前最近一次向UE发送的PUSCH的有效的上行发送波束。
对于上述情况(iii),以第一信号为PUSCH,第一上行传输特性为上行发送波束为例。
在一个示例中:UE接收基站指示UE发送PUSCH的第一指示信息后,发送该第一指示信息对应的PUSCH时,使用UE最近一次发送上行信号使用的上行发送波束。
对于上述情况(iv),仍以第一信号为PUSCH,第一上行传输特性为上行发送波束为例。
在一个示例中:UE接收基站指示UE发送PUSCH的第一指示信息后,发送该第一指示信息对应的PUSCH时,使用UE最近一次发送PUSCH使用的上行发送波束。
在本公开实施例中,第一信号可以为物理上行共享信道(Physical Uplink Shared Channel,PUSCH)、物理上行控制信道(Physical Uplink Control CHannel,PUCCH)、探测参考信号(Sounding Reference Signal,SRS)、随机接入信道(Random Access Channel,RACH)或其他类型的信号。
在本公开实施例中,上行传输特性是指UE使用的一种传输样式(transmission format)。虽然本文中使用上行发送波束作为上行传输特性的一种实施例的示例,需要说明的是,其他的传输特性(不同于UL波束,或者作为UL波束的补充)也同样适用,为便于描述,此处没有针对其他传输特性展开说明。
在本公开实施例中,可选地,所述接收通过所述第一上行传输特性发送的所述第一信号,包括:确定所述上行信号的实际上行发送波束;通过所述实际上行发送波束对应的接收波束接收通过所述第一上行传输特性发送的所述第一信号。
示例1
步骤1、对于一个被调度或触发传输的第一信号,UE确定是否需要使用一个上行传输特性对该第一信号进行波束赋形。如果需要,UE确定网络是否清晰地指示了该第一信号的上行传输特性。
步骤2:如果上行传输特性没有通过网络进行清晰地指示,UE不进行第一信号的传输。
示例2
步骤1:对于一个被调度或触发传输的第一信号,UE确定是否需要使用一个上行传输特性对该第一信号进行波束赋形。如果需要,UE确定网络是否清晰地指示了该第一信号的上行传输特性。
步骤2:如果网络没有清晰地指示上行传输特性,UE确定所述第一信号的上行传输特性。
可选地,UE将其确定的所述第一信号的上行传输特性指示给网络侧设备。该上行传输特性指示可以通过另一个第一信号携带,或者通过所述被调度或触发的第一信号携带。
示例3
步骤1:对于一个被调度或触发传输的第一信号,UE确定是否需要使用一个上行传输特性对该第一信号进行波束赋形。如果需要,UE确定网络是否清晰地指示了该第一信号的上行传输特性。
步骤2:如果网络没有清晰地指示上行传输特性,UE使用网络最近一次清晰指示的上行传输特性作为上行传输特性。
该上行传输特性可以为:最近一次RRC配置的N个波束中的一个预定义的波束,例如,如果N>1,预定义的波束为N个波束中最低序号的波束;如果N=1,预定义的波束为最近一次RRC配置的N个波束。
或者,该上行传输特性可以为:最近一次MAC-CE激活的波束。
示例4
步骤1:对于一个被调度或触发传输的第一信号,UE确定是否需要使用一个上行传输特性对该第一信号进行波束赋形。如果需要,UE确定网络是否清晰地指示了该第一信号的上行传输特性。
步骤2:如果网络没有清晰地指示上行传输特性,UE使用一个默认的上行传输特性。
可选地,默认的上行传输特性为以下任意一项:
最近一次RACH过程中Msg3传输使用的上行传输特性;
最近一次RRC配置的N个波束中的一个预定义的波束,例如:如果N>1,预定义的波束为N个波束中最低序号的波束;如果N=1,预定义的波束为最近一次RRC配置的N个波束;
最近一次MAC-CE激活的波束。
可选地,默认的上行传输特性可以为网络预先定义的。
对于由gNB配置空间波束的第一信号,对UE来说,存在一个上行传输特性不清晰的模糊时段(ambiguity period),包含但不限于以下场景:
场景1:UE尚未接收到关于波束的初始RRC配置。
UE开机后,UE搜索下行同步信道,并读取物理广播信道(PBCH)以获取必要的用于初始接入的系统信息以连接到一个小区。当UE需要通过上行链路接入到所搜索到的小区时,启动初始接入过程(RACH)。初始接入过程包含从UE到gNB的第一消息(Msg1,用于定时估计的上行信息),从gNB到UE的第二消息(Msg2,携带第三消息(Msg3)的调度准许信息),从UE到gNB的Msg3(携带多种UE请求的信息,其中包含RRC连接请求信息),以及从gNB到UE的第四消息(Msg4,携带msg3的确认信息)。Msg4可能携带竞争解决方案(contention resolution)以及发给UE的初始RRC配置信息。
如果UE成功接收到了Msg4,则成功进行了初始接入。需要说明的是,Msg4中的RRC配置信息可能并不包含UE的所有RRC参数,而是只包含一部分RRC参数。在将来的一个时间点可能才传输额外的RRC参数(例如:上行传输特性)。因此,在Msg4的接收和未来的携带上行传输特性信息的RRC信息传输之间的时间段内,UE并不清楚应该用什么样的上行传输特性(即存在一个上行传输特性的模糊时段)。
需要说明的是,即使Msg4中携带了上行传输特性,在上行传输特性生效(例如:通过MAC-CE激活)之前,用于上行传输的上行传输特性对于UE来说仍然是不清晰的,除非(1)RRC上行传输特性配置信息的发送和接收时延是明确定义的,以及(2)配置的上行传输特性应用于上行传输的时间间隔是明确定义的,且UE在从配置上行传输特性到(2)之前不进行任何UL传输。否则,发送波束不清晰的问题仍然存在。
场景2:UE接收到了关于波束的初始RRC配置,但尚未接收到相关联的MAC-CE激活信令。
RRC携带了一组供N个配置的波束,其中N≥1。如果N>1,将有一个MAC-CE激活信息用于从N个配置的波束中选择一个波束用于上行传输。知道MAC-CE激活信息指示的波束生效之前,对于UE来说应该使用哪个上行传输特性都是不清晰(ambiguity)的,除非在上行传输特性不清晰的问题解决之前,不强制UE进行任何上行传输。然而,这并不是总能保证的。例如:用于周期信道状态信息(Channel State Information,CSI)上报的周期地PUCCH,必须在PUCCH资源的RRC配置之后的时刻开始传输,这可能先于MAC-CE激活UL波束之前,这将导致上行传输特性不清晰的问题。
场景3:接收到一个RRC重配信息之后,接收到相关联的MAC-CE激活信息之前。
场景4:当接收到RRC配置和相关联的第一MAC-CE激活信息之后,UE使用第一MAC-CE指示的激活波束,之后UE接收到了第二MAC-CE激活(或重激活)信息,但第二MAC-CE激活的波束尚未生效的时候。
具体地:在接收到RRC配置和MAC-CE激活信息(第一MAC-CE)之后,所指示的激活波束(称其为第一波束)被用于上行传输。在任意一个时间点,gNB可能去激活当前的波束(第一波束),并通过另一个MAC-CE(第二MAC-CE)激活另外一个波束(称其为第二波束)。第一波束的去激活指令和第二波束的激活指令可能在同一个MAC-CE,或者不同的MAC-CE.无论如何,在第二MAC-CE激活的波束(第二波束)生效之前,上行传输特性是不清楚的。
