具体实施方式
下面将结合本申请实施例中的附图，对本申请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申请一部分实施例，而不是全部的实施例。基于本申请中的实施例，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，都属于本申请保护的范围。
本申请的说明书和权利要求书中的术语“第一”、“第二”等是用于区别类似的对象，而不用于描述特定的顺序或先后次序。应该理解这样使用的数据在适当情况下可以互换，以便本申请的实施例能够以除了在这里图示或描述的那些以外的顺序实施。此外，说明书以及权利要求中“和/或”表示所连接对象的至少其中之一，字符“/”，一般表示前后关联对象是一种“或”的关系。
本文所描述的技术不限于长期演进型(Long Term Evolution，LTE)/LTE的演进(LTE-Advanced，LTE-A)系统，并且也可用于各种无线通信系统，诸如码分多址(Code Division Multiple Access，CDMA)、时分多址(Time Division Multiple Access，TDMA)、频分多址(Frequency Division Multiple Access，FDMA)、正交频分多址(Orthogonal Frequency Division Multiple Access，OFDMA)、单载波频分多址(Single-carrier Frequency-Division Multiple Access，SC-FDMA)和其他系统。术语“系统”和“网络”常被可互换地使用。CDMA系统可实现诸如CDMA2000、通用地面无线电接入(Universal Terrestrial Radio  Access，UTRA)等无线电技术。UTRA包括宽带CDMA(Wideband Code Division Multiple Access，WCDMA)和其他CDMA变体。TDMA系统可实现诸如全球移动通信系统(Global System for Mobile Communication，GSM)之类的无线电技术。OFDMA系统可实现诸如超移动宽带(UltraMobile Broadband，UMB)、演进型UTRA(Evolution-UTRA，E-UTRA)、IEEE802.11(Wi-Fi)、IEEE 802.16(WiMAX)、IEEE 802.20、Flash-OFDM等无线电技术。UTRA和E-UTRA是通用移动电信系统(Universal Mobile Telecommunications System，UMTS)的部分。LTE和更高级的LTE(如LTE-A)是使用E-UTRA的新UMTS版本。UTRA、E-UTRA、UMTS、LTE、LTE-A以及GSM在来自名为“第三代伙伴项目”(3rd Generation Partnership Project，3GPP)的组织的文献中描述。CDMA2000和UMB在来自名为“第三代伙伴项目2”(3GPP2)的组织的文献中描述。本文所描述的技术既可用于以上提及的系统和无线电技术，也可用于其他系统和无线电技术。然而，以下描述出于示例目的描述了NR系统，并且在以下大部分描述中使用NR术语，尽管这些技术也可应用于NR系统应用以外的应用。

请参见图1，图1示出本申请实施例可应用的一种无线通信系统的框图。无线通信系统包括终端11和网络侧设备12。其中，终端11也可以称作终端设备或者用户终端(User Equipment，UE)，终端11可以是手机、平板电脑(Tablet Personal Computer)、膝上型电脑(Laptop Computer)、个人数字助理(Personal Digital Assistant，PDA)、移动上网装置(Mobile Internet Device，MID)、可穿戴式设备(Wearable Device)或车载设备等终端侧设备，需要说明的是，在本申请实施例中并不限定终端11的具体类型。网络侧设备12可以是基站或核心网，其中，上述基站可以是5G及以后版本的基站(例如：gNB、5G NR NB等)，或者其他通信系统中的基站(例如：eNB、WLAN接 入点、或其他接入点等)，或者为位置服务器(例如：E-SMLC或LMF(Location Manager Function))，其中，基站可被称为节点B、演进节点B、接入点、基收发机站(Base Transceiver Station，BTS)、无线电基站、无线电收发机、基本服务集(Basic Service Set，BSS)、扩展服务集(Extended Service Set，ESS)、B节点、演进型B节点(eNB)、家用B节点、家用演进型B节点、WLAN接入点、WiFi节点或所述领域中其他某个合适的术语，只要达到相同的技术效果，所述基站不限于特定技术词汇，需要说明的是，在本申请实施例中仅以NR系统中的基站为例，但是本申请实施例并不限定基站的具体类型和具体通信系统。
在massive MIMO技术中如果采用全数字阵列，可以实现最大化的空间分辨率以及最优MU-MIMO性能，但是这种结构需要大量的模数/数模(Analog to Digital，AD/Digital to Analog，DA)转换器件以及大量完整的射频-基带处理通道，无论是设备成本还是基带处理复杂度都将是巨大的负担。
为了避免上述的实现成本与设备复杂度，数模混合波束赋形技术应运而生，即在传统的数字域波束赋形基础上，在靠近天线系统的前端，在射频信号上增加一级波束赋形。模拟赋形能够通过较为简单的方式，使发送信号与信道实现较为粗略的匹配。模拟赋形后形成的等效信道的维度小于实际的天线数量，因此其后所需的AD/DA转换器件、数字通道数以及相应的基带处理复杂度都可以大为降低。模拟赋形部分残余的干扰可以在数字域再进行一次处理，从而保证MU-MIMO传输的质量。相对于全数字赋形而言，数模混合波束赋形是性能与复杂度的一种折中方案，在高频段大带宽或天线数量很大的系统中具有较高的实用前景。
在对4G以后的下一代通信系统研究中，将系统支持的工作频段提升至6GHz以上，最高约达100GHz。高频段具有较为丰富的空闲频率资源，可以为数据传输提供更大的吞吐量。高频信号的波长短，同低频段相比，能够在同样大小的天线面板上布置更多的天线阵元，利用波束赋形技术形成指向性更强、波瓣更窄的波束。因此，将大规模天线和高频通信相结合，也是未来的趋势之一。
模拟波束赋形是全带宽发射的，并且每个高频天线阵列的天线面板上每 个极化方向阵元仅能以时分复用的方式发送模拟波束。模拟波束的赋形权值是通过调整射频前端移相器等设备的参数来实现。
目前，通常是使用轮询的方式进行模拟波束赋形向量的训练，即每个天线面板每个极化方向的阵元以时分复用方式依次在约定时间发送训练信号(即候选的赋形向量)，终端经过测量后反馈波束报告，供网络侧在下一次传输业务时采用该训练信号来实现模拟波束发射。波束报告的内容通常包括最优的若干个发射波束标识及其对应的接收功率或信干噪比。
在做波束测量(beam measurement)时，网络会配置参考信号资源集合(RS resource set)，其中包括至少一个参考信号资源，例如SSB resource或信道状态信息参考信号(Channel State Information Reference Signal，CSI-RS)resource。UE测量每个RS resource的L1-RSRP/L1-SINR，并将最优的至少一个测量结果上报给网络，上报内容包括SSBRI或CRI、及对应的L1-RSRP/L1-SINR。该报告内容反映了至少一个最优的波束及其质量，供网络确定用来与UE传输信道或信号的波束信息。
在经过波束测量和波束报告后，网络可以对下行与上行链路的信道或参考信号做波束指示(beam indication)，用于网络与UE之间建立波束链路，实现信道或参考信号的传输。
对于PDCCH的波束指示，网络使用无线资源控制(Radio Resource Control，RRC)信令为每个控制资源集(control-resource set，CORESET)配置K个传输配置指示(Transmission Configuration Indication，TCI)state，当K>1时，由媒体介入控制控制元素(MAC CE)指示或激活1个TCI state，当K＝1时，不需要额外的MAC CE命令。UE在监听PDCCH时，对CORESET内全部搜索空间(search space)使用相同准共址(Quasi-colocation，QCL)信息，即使用相同的TCI state来监听PDCCH。该TCI状态中的源参考信号(referenceSignal)(例如周期CSI-RS resource、半持续CSI-RS resource、SS block等)与UE-specific PDCCH解调参考信号(Demodulation Reference Signal，DMRS)端口是空间QCL的。UE根据该TCI状态即可获知使用哪个接收波束来接收PDCCH。
对于物理下行控制信道(Physical Downlink Control Channel，PDSCH)的 波束指示，网络通过RRC信令配置M个TCI state，再使用MAC CE命令激活2 N个TCI state，然后通过下行控制信息(Downlink Control Information,DCI)的N-bit TCI field来通知TCI状态，该TCI状态中的referenceSignal与要调度的PDSCH的DMRS端口是QCL的。UE根据该TCI状态即可获知使用哪个接收波束来接收PDSCH。
对于CSI-RS的波束指示，当CSI-RS类型为周期CSI-RS时，网络通过RRC信令为CSI-RS resource配置QCL信息。当CSI-RS类型为半持续CSI-RS时，网络通过MAC CE命令来从RRC配置的CSI-RS resource set中激活一个CSI-RS resource时指示其QCL信息。当CSI-RS类型为非周期CSI-RS时，网络通过RRC信令为CSI-RS resource配置QCL，并使用DCI来触发CSI-RS。
对于物理上行控制信道(Physical Uplink Control Channel，PUCCH)的波束指示，网络使用RRC信令通过参数PUCCH-SpatialRelationInfo为每个PUCCH resource配置空间关系信息(spatial relation information)，当为PUCCH resource配置的spatial relation information包含多个时，使用MAC-CE激活其中一个spatial relation information。当为PUCCH resource配置的spatial relation information只包含1个时，不需要额外的MAC CE命令。
对于物理上行共享信道(Physical Uplink Shared Channel，PUSCH)的波束指示，PUSCH的spatial relation信息是当PDCCH承载的DCI调度PUSCH时，DCI中的探测参考信号资源指示(SRS resource indicator，SRI)域(field)的每个SRI代码点(codepoint)指示一个SRI，该SRI用于指示PUSCH的spatial relation information。
对于探测参考信号(Sounding Reference Signal，SRS)的波束指示，当SRS类型为周期SRS时，网络通过RRC信令为SRS resource配置spatial relation information。当SRS类型为半持续SRS时，网络通过MAC CE命令来从RRC配置的一组spatial relation information中激活一个。当SRS类型为非周期SRS时，网络通过RRC信令为SRS resource配置spatial relation information，还可以使用MAC CE命令更新非周期SRS resource的spatial relation information。
其中，上述所提及的波束信息，也可以称为：波束信息、空间关系(spatial  relation)信息、空域发送滤波器(spatial domain transmission filter)信息、空域滤波器(spatial filter)信息、传输配置指示状态(TCI state)信息、准共址(QCL)信息或QCL参数等。其中，下行波束信息通常可使用TCI state信息或QCL信息表示。上行波束信息通常可使用spatial relation信息表示。
所提及的天线面板(Panel)，也可以称为：天线组、天线端口组、天线集合、天线端口集合、波束集合、波束子集合、天线阵列、天线端口阵列、天线子阵列、天线端口子阵列、逻辑实体、实体或天线实体等。
Panel的标识可以为：天线面板的标识、参考信号资源标识、参考信号资源集标识、TCI状态标识、QCL信息标识、空间关系标识等。
本申请实施例提供了一种获取通信资源的方法，如图2所示，所述方法包括：
步骤101：终端接收来自网络侧设备的第一指示信息，所述第一指示信息用于指示信道或参考信号的传输，所述第一指示信息包括波束信息和/或天线面板信息。
在本申请实施例中，网络侧设备向终端发送第一指示信息，第一指示信息用于指示信道或参考信号的传输，第一指示信息包括波束信息和/或天线面板信息，这样在终端支持多天线面板时，网络侧设备可以对天线面板的切换和/或波束的切换进行指示，支持对多天线面板的终端的数据传输，指示终端进行天线面板选择和/或天线面板切换，使得终端能够选择最优的天线面板上的波束进行传输，保证通信性能。
一些实施例中，所述第一指示信息包括以下任一项：
所述网络侧设备根据上行链路性能和下行链路性能确定的波束信息和/或天线面板信息；
所述网络侧设备根据上行链路性能或下行链路性能确定的波束信息和/或天线面板信息，这时，上行波束和下行波束可以不同，上行波束或下行波束可以为当前激活的天线面板上的波束或者为未激活的天线面板上的波束。
一些实施例中，所述根据上行链路性能和下行链路性能确定的波束信息和/或天线面板信息包括以下至少一项：
根据当前波束和待切换波束之间的下行链路的第一参数值差值是否满足 第一预设条件，以及当前波束和待切换波束之间的上行链路的第二参数值差值是否满足第二预设条件，所确定的波束信息；
根据当前激活的天线面板和未激活的天线面板上的下行链路的第三参数值差值是否满足第三预设条件，以及当前激活的天线面板和未激活的天线面板上的上行链路的第四参数值差值是否满足第四预设条件，所确定的天线面板信息；
根据当前波束所在天线面板和其他天线面板上的下行链路的第五参数值差值是否满足第五预设条件，以及当前波束所在天线面板和其他天线面板上的上行链路的第六参数值差值是否满足第六预设条件，所确定的天线面板信息。
其中，所述第一参数值为下行链路质量值；
所述第二参数值包括以下至少一项：上行链路质量值、发射功率、波束的功率管理-最大功率降低值。
上行链路质量值、下行链路质量值可以是采用以下任一质量参数或以下任一质量参数连续多次测量得到的平均值：参考信号接收功率RSRP；参考信号接收质量RSRQ；信号与干扰加噪声比SINR；接收的信号强度指示RSSI。
其中，网络侧设备根据上行链路性能和下行链路性能确定的波束信息和/或天线面板信息可以是在终端支持一个波束传输的情况下，根据当前波束和待切换波束之间的下行链路的第一参数值差值是否满足第一预设条件，以及当前波束和待切换波束之间的上行链路的第二参数值差值是否满足第二预设条件，所确定的波束信息。在终端能力仅支持一个波束传输的情况下，下行波束和上行波束具有波束一致性，即终端的上行发送波束与下行接收波束的波束信息除了方向以外都相同，对于网络侧设备的下行发送波束与上行接收波束也是同理。也就是说，下行波束和上行波束对应的是同一个波束链路。正因为如此，如果终端因为当前波束的上行链路质量较差而需要从当前上行波束切换到待切换上行波束，那么对于下行链路，也需要从当前下行波束切换到待切换下行波束，终端在进行波束切换后上行链路质量可能会变好，但是可能会导致波束的下行链路质量变得比较差，因此在进行切换时不能仅考虑上行链路质量或下行链路质量，需要兼顾上行链路质量和下行链路质量。
其中，所述网络侧设备根据上行链路性能和下行链路性能确定的天线面板信息可以是在终端支持一个激活天线面板的情况下，根据当前激活的天线面板和未激活的天线面板上的下行链路的第三参数值差值是否满足第三预设条件，以及当前激活的天线面板和未激活的天线面板上的上行链路的第四参数值差值是否满足第四预设条件，所确定的天线面板信息。在终端能力仅支持一个激活天线面板的情况下，如果终端因为当前激活面板的上行波束的上行链路质量较差，而需要从当前激活的天线面板切换至未激活的天线面板，终端将待切换至的未激活的天线面板激活，将原激活的天线面板去激活，使用新激活的天线面板上的上行波束获得较优的上行链路质量，那么下行波束也需要切换至新激活的天线面板上，终端在进行天线面板切换后上行链路质量可能会变好，但是可能会导致下行链路质量变得比较差，因此在进行天线面板切换时不能仅考虑上行链路质量或下行链路质量，需要兼顾上行链路质量和下行链路质量。
其中，上述预设条件可以为网络侧设备配置或协议约定。
一些实施例中，若所述第一指示信息包括所述网络侧设备根据上行链路性能或下行链路性能确定的波束信息和/或天线面板信息，所述波束为当前激活天线面板上的波束或为当前未激活天线面板上的波束。
一些实施例中，若所述信道或参考信号为非周期性的信道或参考信号，所述第一指示信息与所述信道或参考信号之间的时间偏移值大于或等于波束切换或天线面板切换所需的时长。这样可以为终端预留时间进行波束切换或天线面板切换，保证通信的连续性。
本实施例中，第一指示信息具体可以为下行控制信息DCI。
一些实施例中，所述信道包括以下至少一项：上行物理共享信道PUSCH、下行物理共享信道PDSCH；
所述参考信号包括以下至少一项：CSI-RS、SRS。
一些实施例中，所述时间偏移值采用协议约定的或网络侧设备配置的用于波束切换或天线面板切换的至少一个偏移值。可以协议约定或网络侧设备配置多个偏移值，使用多个偏移值中的至少一个偏移值作为所述时间偏移值。
一些实施例中，若需要进行天线面板切换，所述方法还包括获取第二指 示信息，所述第二指示信息包括以下至少一项：
所述网络侧设备配置的候选TCI状态或TCI状态池或候选空间关系或空间关系池；
所述网络侧设备激活的一组TCI状态或QCL信息或空间关系；
所述网络侧设备激活的或指示的所述信道或参考信号的TCI状态或QCL信息或空间关系；
所述网络侧设备指示的待切换的目标天线面板的标识信息。
其中，第二指示信息可以为无线资源控制RRC信令、媒体介入控制MAC控制元素CE命令或下行控制信息DCI信令。

方式一，网络侧设备可以通过高层信令比如RRC信令为终端配置与天线面板对应的信息池，可称为TCI状态池、或候选TCI状态池、或空间关系池、或候选空间关系池，在信息池中包括多个TCI状态或QCL信息或空间关系，若终端支持多个天线面板，则为每个天线面板配置对应的信息池。之后网络侧设备可以从一个信息池中通过MAC CE激活一组TCI状态或QCL信息或空间关系，或者通过RRC信令或MAC CE命令或DCI信令(如所述第一指示信息)从一个信息池中指示TCI状态或QCL信息或空间关系，或者，从所述MAC CE激活的一组TCI状态或QCL信息或空间关系中指示TCI状态或QCL信息或空间关系，那么，根据信息池与天线面板的对应关系，即可确定第一指示信息指示的信道或参考信号是对应终端的哪个天线面板，该天线面板是网络侧设备将要与其进行传输的。
方式二，网络侧设备为终端配置的信息池与终端的天线面板没有对应关系，在所述网络侧设备使用MAC CE命令从所述信息池中激活一组TCI状态或QCL信息或空间关系时，所述激活的一组TCI状态或QCL信息或空间关系与终端的天线面板对应。然后，网络侧设备通过RRC信令或MAC CE命令或DCI信令(如所述第一指示信息)从所述MAC CE激活的一组TCI状态或QCL信息或空间关系中指示TCI状态或QCL信息或空间关系，那么，根据所述激活的一组TCI状态或QCL信息或空间关系与天线面板的对应关系， 即可确定第一指示信息指示的信道或参考信号是对应终端的哪个天线面板，该天线面板是网络侧设备将要与其进行传输的。
方式三，网络侧设备为终端配置的所述信息池和/或网络侧设备使用MAC CE命令激活的一组TCI状态或QCL信息或空间关系与终端天线面板没有对应关系，网络侧设备可以使用RRC信令指示或MAC CE命令激活或DCI信令指示TCI状态或QCL信息或空间关系，所述激活或指示的TCI状态或QCL信息或空间关系与天线面板具有对应关系，或者所述激活或指示的TCI状态或QCL信息或空间关系中的源参考信号与天线面板具有对应关系，据此即可确定第一指示信息指示的信道或参考信号是对应终端的哪个天线面板，该天线面板是网络侧设备将要与其进行传输的。

其中，上述方式一至方式三是隐式指示目标天线面板，方式四是显式指示目标天线面板。
一些实施例中，第二指示信息与第一指示信息不同，并且第二指示信息在第一指示信息之前由网络侧设备发送给终端。终端根据第二指示信息确定天线面板信息，并使用所确定的天线面板与网络侧设备传输由第一指示信息指示的信道或参考信号。
一些实施例中，第二指示信息与第一指示信息不同，并且第二指示信息在第一指示信息之后由网络侧设备发送给终端。

一些实施例中，第二指示信息与第一指示信息相同，即在第一指示信息中携带天线面板信息，例如显式携带天线面板标识，或隐式的通过与天线面板对应的TCI状态或QCL信息或空间关系，来确定天线面板信息。一些实施例中，如果第一指示信息指示的信道或参考信号与天线面板具有对应关系，那么在进行天线面板切换时，根据第一指示信息即可确定待切换的目标天线面板，这时就不需要再通过第二指示信息指示待切换的目标天线面板。

本申请实施例提供了一种指示通信资源的方法，如图3所示，所述方法包括：
步骤201：网络侧设备向终端发送第一指示信息，所述第一指示信息用于指示信道或参考信号的传输，所述第一指示信息包括波束信息和/或天线面板信息。
在本申请实施例中，网络侧设备向终端发送第一指示信息，第一指示信息用于指示信道或参考信号的传输，第一指示信息包括波束信息和/或天线面板信息，这样在终端支持多天线面板时，网络侧设备可以对天线面板的切换和/或波束的切换进行指示，支持对多天线面板的终端的数据传输，指示终端进行天线面板选择和/或天线面板切换，使得终端能够选择最优的天线面板上的波束进行传输，保证通信性能。
一些实施例中，所述第一指示信息包括以下任一项：
根据上行链路性能和下行链路性能确定的波束信息和/或天线面板信息；
根据上行链路性能或下行链路性能确定的波束信息和/或天线面板信息。
一些实施例中，
所述根据上行链路性能和下行链路性能确定的波束信息和/或天线面板信息包括以下至少一项：
根据当前波束和待切换波束之间的下行链路的第一参数值差值是否满足第一预设条件，以及当前波束和待切换波束之间的上行链路的第二参数值差值是否满足第二预设条件，所确定的波束信息；
根据当前激活的天线面板和未激活的天线面板上的下行链路的第三参数值差值是否满足第三预设条件，以及当前激活的天线面板和未激活的天线面板上的上行链路的第四参数值差值是否满足第四预设条件，所确定的天线面板信息；
根据当前波束所在天线面板和其他天线面板上的下行链路的第五参数值差值是否满足第五预设条件，以及当前波束所在天线面板和其他天线面板上的上行链路的第六参数值差值是否满足第六预设条件，所确定的天线面板信息。
其中，所述第一参数值为下行链路质量值；
所述第二参数值包括以下至少一项：上行链路质量值、发射功率、波束的功率管理-最大功率降低值。
上行链路质量值、下行链路质量值可以是采用以下任一质量参数或以下任一质量参数连续多次测量得到的平均值：参考信号接收功率RSRP；参考信号接收质量(Reference Signal Receiving Quality，RSRQ)；信号与干扰加噪声比(Signal to Interference plus Noise Ratio，SINR)；接收的信号强度指示(Received Signal Strength Indication，RSSI)。
其中，网络侧设备根据上行链路性能和下行链路性能确定的波束信息和/或天线面板信息可以是在终端支持一个波束传输的情况下，根据当前波束和待切换波束之间的下行链路的第一参数值差值是否满足第一预设条件，以及当前波束和待切换波束之间的上行链路的第二参数值差值是否满足第二预设条件，所确定的波束信息。在终端能力仅支持一个波束传输的情况下，下行波束和上行波束具有波束一致性，即终端的上行发送波束与下行接收波束的 波束信息除了方向以外都相同，对于网络侧设备的下行发送波束与上行接收波束也是同理。也就是说，下行波束和上行波束对应的是同一个波束链路。正因为如此，如果终端因为当前波束的上行链路质量较差而需要从当前上行波束切换到待切换上行波束，那么对于下行链路，也需要从当前下行波束切换到待切换下行波束，终端在进行波束切换后上行链路质量可能会变好，但是可能会导致波束的下行链路质量变得比较差，因此在进行切换时不能仅考虑上行链路质量或下行链路质量，需要兼顾上行链路质量和下行链路质量。
其中，所述网络侧设备根据上行链路性能和下行链路性能确定的天线面板信息可以是在终端支持一个激活天线面板的情况下，根据当前激活的天线面板和未激活的天线面板上的下行链路的第三参数值差值是否满足第三预设条件，以及当前激活的天线面板和未激活的天线面板上的上行链路的第四参数值差值是否满足第四预设条件，所确定的天线面板信息。在终端能力仅支持一个激活天线面板的情况下，如果终端因为当前激活面板的上行波束的上行链路质量较差，而需要从当前激活的天线面板切换至未激活的天线面板，终端将待切换至的未激活的天线面板激活，将原激活的天线面板去激活，使用新激活的天线面板上的上行波束获得较优的上行链路质量，那么下行波束也需要切换至新激活的天线面板上，终端在进行天线面板切换后上行链路质量可能会变好，但是可能会导致下行链路质量变得比较差，因此在进行天线面板切换时不能仅考虑上行链路质量或下行链路质量，需要兼顾上行链路质量和下行链路质量。
其中，上述预设条件可以为网络侧设备配置或协议约定。
一些实施例中，若所述第一指示信息包括所述网络侧设备根据上行链路性能或下行链路性能确定的波束信息和/或天线面板信息，所述波束为当前激活天线面板上的波束或为当前未激活天线面板上的波束。
一些实施例中，若所述信道或参考信号为非周期性的信道或参考信号，所述第一指示信息与所述信道或参考信号之间的时间偏移值大于或等于波束切换或天线面板切换所需的时长。
一些实施例中，所述信道包括以下至少一项：上行物理共享信道PUSCH、下行物理共享信道PDSCH；
所述参考信号包括以下至少一项：CSI-RS、SRS。
一些实施例中，所述时间偏移值采用协议约定的或网络侧设备配置的用于波束切换或天线面板切换的至少一个偏移值。
一些实施例中，若需要进行天线面板切换，所述方法还包括向所述终端发送第二指示信息，所述第二指示信息包括以下至少一项：

一些实施例中，根据第二指示信息确定天线面板信息的方式可有如下方式：
方式一，网络侧设备可以通过高层信令比如RRC信令为终端配置与天线面板对应的信息池，可称为TCI状态池、或候选TCI状态池、或空间关系池、或候选空间关系池，在信息池中包括多个TCI状态或QCL信息或空间关系，若终端支持多个天线面板，则为每个天线面板配置对应的信息池。之后网络侧设备可以从一个信息池中通过MAC CE激活一组TCI状态或QCL信息或空间关系，或者通过RRC信令或MAC CE命令或DCI信令(如所述第一指示信息)从一个信息池中指示TCI状态或QCL信息或空间关系，或者，从所述MAC CE激活的一组TCI状态或QCL信息或空间关系中指示TCI状态或QCL信息或空间关系，那么，根据信息池与天线面板的对应关系，即可确定第一指示信息指示的信道或参考信号是对应终端的哪个天线面板，该天线面板是网络侧设备将要与其进行传输的。
方式二，网络侧设备为终端配置的信息池与终端的天线面板没有对应关系，在所述网络侧设备使用MAC CE命令从所述信息池中激活一组TCI状态或QCL信息或空间关系时，所述激活的一组TCI状态或QCL信息或空间关 系与终端的天线面板对应。然后，网络侧设备通过RRC信令或MAC CE命令或DCI信令(如所述第一指示信息)从所述MAC CE激活的一组TCI状态或QCL信息或空间关系中指示TCI状态或QCL信息或空间关系，那么，根据所述激活的一组TCI状态或QCL信息或空间关系与天线面板的对应关系，即可确定第一指示信息指示的信道或参考信号是对应终端的哪个天线面板，该天线面板是网络侧设备将要与其进行传输的。
方式三，网络侧设备为终端配置的所述信息池和/或网络侧设备使用MAC CE命令激活的一组TCI状态或QCL信息或空间关系与终端天线面板没有对应关系，网络侧设备可以使用RRC信令指示或MAC CE命令激活或DCI信令指示TCI状态或QCL信息或空间关系，所述激活或指示的TCI状态或QCL信息或空间关系与天线面板具有对应关系，或者所述激活或指示的TCI状态或QCL信息或空间关系中的源参考信号与天线面板具有对应关系，据此即可确定第一指示信息指示的信道或参考信号是对应终端的哪个天线面板，该天线面板是网络侧设备将要与其进行传输的。
方式四，网络侧设备使用RRC信令或MAC CE命令或DCI信令发送目标天线面板的标识信息，终端据此确定所需使用或所需切换至的目标天线面板。

一些实施例中，第二指示信息与第一指示信息相同，即在第一指示信息中携带天线面板信息，例如显式携带天线面板标识，或隐式的通过与天线面板对应的TCI状态或QCL信息或空间关系，来确定天线面板信息。
一些实施例，如果第一指示信息指示的信道或参考信号与天线面板具有对应关系，那么在进行天线面板切换时，根据第一指示信息即可确定待切换的目标天线面板，这时就不需要再通过第二指示信息指示待切换的目标天线面板。
一些实施例中，可以通过DCI携带第二指示信息，在PDCCH和PDSCH之间传输第二指示信息。
