背景技术
相关技术中引入了解调参考信号(Demodulation Reference Signal，DMRS)捆绑(bundling)的功能，即在多个上行传输之间在一定的时间窗内需要保持功率稳定和相位连续，使得网络可以在这个时间窗基于多个上行传输联合进行信道估计，以提升接收性能。
然而，由于UE能力的限制或时分双工(Time Division Duplexing，TDD)帧结构或一些上行不可用时隙的存在，会导致上述时间窗的长度可能超出UE能够保证功率稳定和相位连续的范围，进一步地，时间窗内的多个传输之间也可能存在下行传输，或较多上行传输不可用的时隙，会增加对UE能力的要求，甚至无法满足功率稳定和相位连续的条件。例如，时分双工(Time Division Duplexing，TDD)帧结构中，在上行(uplink，UL)时隙(slots)之间会存在较多的下行(downlink，DL)slots；又例如，可能一些高优先级的传输会终止(cancel)掉当前的上行传输，而无法保证功率稳定和相位连续的条件。

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术语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，且“第一”、“第二”所区别的对象通常为一类，并不限定对象的个数，例如第一对象可以是一个，也可以是多个。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。
值得指出的是，本申请实施例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，还可用于其他无线通信系统，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。本申请实施例中的术语“系统”和“网络”常被可互换地使用，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。以下描述出于示例目的描述了新空口(New Radio，NR)系统，并且在以下大部分描述中使用NR术语，但是这些技术也可应用于NR系统应用以外的应用，如第6代(6th Generation，6G)通信系统。
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)或称为笔记本电脑、个人数字助理(Personal Digital Assistant，PDA)、掌上电脑、上网本、超级移动个人计算机(ultra-mobile personal computer，UMPC)、移动上网装置(Mobile Internet Device，MID)、可穿戴式设备(Wearable Device)或车载设备(VUE)、行人终端(PUE)等终端侧设备，可穿戴式设备包括：智能手表、手环、耳机、眼镜等。需要说明的是，在本申请实施例并不限定终端11的具体类型。网络侧设备12可以是基站或核心网，其中，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、无线局域网(Wireless Local Area Network，WLAN)接入点、无线通信技术(WiFi)节点、发送接收点(Transmitting Receiving Point，TRP)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新空口(New Radio，NR)系统中的基站为例，但是并不限定基站的具体类型，所述核心网设备可以是位置管理设备，例如，所位置管理功能(LMF、E-SLMC)等。
用户设备(User Equipment，UE)可以在一定的时间窗内的多个物理上行共享信道(Physical Uplink Shared Channel，PUSCH)传输的过程中保持功率和相位的连续性，这样网络在接收该多个PUSCH的情况下，可以基于其中一个PUSCH的解调参考信号(Demodulation Reference Signal，DMRS)获得对于其他PUSCH传输的信道信息，则可以使用该多个PUSCH中的DMRS进行联合信道估计，以提升接收性能，该技术称为DMRS bundling。其中的 时间窗称为bundling window或time domain window。
该多个PUSCH可以为相同传输块的重复传输，可以是不同的传输块，可以是同一个传输块在多个时隙(slot)上的传输(TB processing over multiple-slots)。该多个PUSCH可以在相同的slot传输或者在不同的slot传输。
多个传输之间可以为不连续的传输，即可以间隔X个符号或者时隙的情况下，终端在不需要满足掉电要求(off-power requirement)的情况下，可以实现非连续的传输之间保持功率恒定和相位连续。所述off-power requirement为终端在关闭发射机的情况下，辐射功能不能超过预设门限的指标要求。不需要满足该要求，则说明终端可以在不发送信号的时候，不关闭发射机，以保持不连续的传输之间的功率恒定和相位连续。
上述方案也适用于多个物理上行控制信道(Physical Uplink Control Channel，PUCCH)传输进行DMRS bundling的优化。
DMRS bundling技术中，UE在一定的时间窗内的多个上行传输之间，可以基于其中一个传输的DMRS推测出其他传输的信道，则UE需要满足传输功率恒定和相位连续之外，还需要满足一些额外的条件，包括以下至少其中之一：
在多个传输之间的发送功率不变；
在多个传输之间的频域分配的无线承载(Radio Bearer，RB)数不变；
两个上行传输之间的间隔(gap)不超过X个符号(symbol)或者slot；
两个上行传输之间不进行频率切换；
两个上行传输之间不调度下行传输；
多个传输之间使用相同的调制方式。
需要一种根据实际传输过程对时间窗进行动态确定或划分的方法，能够较大程度上保证实际时间窗内更多连续可用的上行传输时机，以保证传输的实际时间窗内能够满足功率稳定和相位连续的条件，从而使得网络通过联合信道估计提升接收性能，进而提高覆盖能力。

步骤101：获取第一指示；
步骤102：根据所述第一指示和第一规则，确定一个或多个上行传输之间满足第一传输特性的第一时间窗。
其中，第一时间窗为实际时间窗(actual window)。

下面结合附图以及具体的实施例对本申请的技术方案进行进一步介绍：
一实施例中，假设对于某一上行重复传输类型A(PUSCH repetition type A)，配置的重复次数为8次，通过预定义的方式，确定名义时间窗大小为该重复次数，即对应8slots。而此时UE能够保持满足第一传输特性的传输所对应的最大时间为4slots，那么，对于FDD系统，根据第一规则确定的实际时间窗如图4所示。若跳频的interval大于等于4slots，则对应的跳频pattern如图5所示。
对于TDD系统，假设半静态帧结构为”DDDSUDDSUU”，则根据第一规则确定的实际时间窗如图6所示，对应的跳频pattern如图7所示，其中，1st hop为第一跳，2nd hop为第二跳，第一跳和第二跳位于不同的频域位置。

考虑使能跳频时，对于两个连续或非连续符号间隔小于X的actual window可以使用相同的跳频位置，则对应的跳频pattern如图10所示。
对于TDD系统，在该重复传输中因SFI/CI导致其中某些slots不可用，根据第一规则确定的实际时间窗如图11所示，若此时配置的跳频interval为1slots，则跳频的pattern如图12所示。
进一步地，考虑使能跳频时，对于两个连续或非连续符号间隔小于X的actual window可以使用相同的跳频位置，则对应的跳频pattern如图13所示，若此时配置的跳频interval为2slots，则跳频的pattern如图14所示。
